63/166,636, filed on March 26, 2021, claims the benefit of U.S. Patent Application Serial No. 63/197,040, filed on June 4, 2021 and claims the benefit of U.S. Patent Application Serial No. 63/278,941, filed on November 12, 2021, the disclosures of which are incorporated herein by reference in their entireties. Background

In the telecommunications industry, the demand for added capacity is growing rapidly. This demand is being met in part by the increasing use and density of fiber optic transmission equipment. Even though fiber optic equipment permits higher levels of transmission in the same or smaller footprint than traditional copper transmission equipment, the demand requires even higher levels of fiber density. This has led to the development of high-density fiber handling equipment.

In communications panel systems, port members (e.g., optical adapters, electrical jacks, hybrid port members, etc.) defining front ports are mounted to one or more trays that are disposable within a chassis. The front ports are configured to receive plug connectors at the fronts of the trays. The trays can either he stationary within a chassis or can slide forwardly of the chassis to enhance access to the port members, improvements are desired.

Summary

Some aspects of the disclosure are directed to a latching arrangement by which a tray arrangement can be releasably held in one or more positions relative to a chassis, the positions aligned along a forward-rearward axis of the chassis. In certain implementations, the tray arrangement can be releasably held in a retracted position where the tray arrangement is fully disposed within the chassis and in an extended position where the tray arrangement extends through a front of the chassis. In certain implementations, the latching arrangement is actuated by movement of a cable guide extending forwardly of the tray arrangement. In some implementations, the cable guide is pivoted relative to the tray arrangement to actuate the latching arrangement, in other implementations, the cable guide is slid along the forward- rearward axis, in certain examples, movement of the cable guide releases only one of multiple stop members of the latching arrangement.

In some implementations, the latching arrangement includes first and second deflection members that cooperate to releasabiy retain the tray arrangement in one of the one or more positions through engagement of one or more catch surfaces defined by the chassis. The first deflection member defines the cable guide to be moved to actuate the latching arrangement. The stop member actuated by the cable guide can be defined by either the first deflection member or the second deflection member.

In certain implementations, one of tire first and second deflection members defines a biasing member to bias the first and second deflection members to neutral positions. Each of the first and second deflection members is moved to a respective actuated position against the bias of the biasing member. In an example, the biasing member includes a leaf spring.

In certain implementations, the second deflection member defines a stop member that is not actuated by the cable guide. Rather, this stop member is actuated by- pressing against an actuation leg of the second deflection member. The stop member actuated by the actuation leg moves independent of the stop member actuated by the cable guide. In some examples, the actuation leg defines a biasing member. In an example, the biasing member has a convex curvature when not actuated. In another example, the biasing member has a concave curvature when not actuated, in other examples, the actuation leg is rigid.

In other implementations, the latching arrangement includes a deflection arrangement and an actuation member that cooperate to releasably retain the tray arrangement in one of the one or more positions through engagement of one or more catch surfaces defined by the chassis. The actuation member defines the cable guide to be moved to actuate the latching arrangement. The deflection arrangement defines the stop member actuated by the actuation member. The stop member moves along an axis transverse to the movement axis of the actuation member. In certain examples, the actuation member slides along the forward-rearward axis of the chassis. In certain implementations, one of more cable guides (e.g., front cable guides, rear cable guides, etc.) can be magnetically mounted to the tray arrangement. In certain example, each cable guide holds one or more magnets within respective cavities defined within a body of the cable guide. As the term is used herein, a cable guide refers to a guide for cables, fibers, conductors, or oilier elongate media segment carrying data signals or power or conduit (e.g., buffer tube) surrounding the same.

A variety of additional inventive aspects will be set forth in the description that follows. Tire inventive aspects can relate to individual features and to combinations of features, it is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the broad inventive concepts upon which the embodiments disclosed herein are based.

Reference will now be made in detail to exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

The present disclosure is directed to a communications panel 100 configured to mount to a rack. The communications panel 100 includes a chassis 102 holding one or more tray arrangements 120. The chassis 102 extends along a forward- rearward axis FR between a front 104 and a rear 106. Tire chassis 102 also extends along a lateral axis LA between opposite first and second sides 108, 110. The chassis 102 also has a height H extending between a bottom and a top. A cover may be mounted over the top of the chassis 102. In certain examples, the cover is removable. Example chassis 102 suitable for use with the tray arrangements 120 disclosed herein are described in co- pending U.S. provisional application No. 63/166,576, filed March 26, 2021, titled "‘Communications Panel Systems,” and having attorney docket number 02316.8248USP1, and U.S. provisional application No. 63/197,018, filed June 04, 2021, and titled “Communications Panel Systems,” the disclosures of which are hereby incorporated by reference in their entirety.

In certain implementations, mounting brackets 112 are disposed at the first and second sides 108, 110 and configured to mount the chassis 102 to the rack. In certain implementations, a cable management section is disposed at the rear 106 of the chassis 102 to manage cables extending to the chassis 102 from the rear. A removable cover 114 is mounted over tire cable management section. In certain examples, the removable cover 114 is flush with the top of the chassis 102. in certain examples, sides of the cable management section remain uncovered to facilitate cable routing to the cable management section.

Referring to FIG. 2, each tray arrangement 120 spans a width W along the lateral axis LA of the chassis 102. In certain implementations, multiple tray arrangements 120 are received in a common chassis 102. For example, the tray arrangements 120 can be disposed one-above-the-other within an interior of the chassis 102. Each tray arrangement 120 includes a tray 121 configured to support one or more cassettes carrying optical equipment such as splices, splitters, and/or ports (e.g., optical ports, electrical ports, hybrid ports, etc.) configured to receive plug connectors. Examples cassettes and example interfaces between such cassettes and the tray are provided in co-pending U.S. Provisional Application No. 63/150,828, filed February 18, 2021, and titled “Communications Panel System” and co-pending U.S. provisional application No. 63/214,106, filed June 2.3, 2021, titled “Communications Panel System,” the disclosures of which are hereby incorporated herein by reference in their entirety.

In some implementations, the tray arrangements 120 are stationary within the chassis 102. in other implementations, the tray arrangements 120 are slidable along the forward-rearward axis FR of the chassis 102 between two or more positions. For example, the tray arrangements 120 may be slidable between a retracted position (e.g., see FIG. 2) and an extended position (e.g., see FIG. 3). When disposed in the retracted position, the tray arrangement 120 is fully disposed within the chassis 102 (e.g., a front 122 of the tray arrangement 120 is disposed no further forward than the front 104 of the chassis 102 and a rear 124 of the tray arrangement 120 is disposed no further rearward than the rear 106 of the chassis 102). When disposed in the extended position, a portion of the tray arrangement 120 (e.g., the front 122) is disposed external of the chassis 102 (e.g., forward of the front 104 of the chassis 102). in certain implementations, the tray arrangement 120 includes one or more cable guides 126 extending forwardly of the front 122 of the tray arrangement 120. Each cable guide 12.6 defines a through-passage T along which one or more cables can be guided. In certain examples, the through-passage T extends parallel with the lateral axis LA of the tray arrangement 120. In certain implementations, the tray arrangement 120 can be transitioned between the retracted position and the extended position by using one or more of the cable guides 126 as a handle to pull or push the tray 120 relative to the chassis 102

FIG. 4 illustrates an interior 130 of the chassis 102. The chassis 102 includes guides 132. disposed at interior sidewalls 134 at the sides 108, 110 of the chassis 102. The guides 132 extend along the forward-rearward axis FRofthe chassis 102. As shown in FIG. 5, the tray arrangement 120 includes rails 128 disposed at opposite first and second sides of the tray 12.0. The rails 128 extend laterally outwardly from the tray arrangement 120 in opposite directions. Each of the rails 128 is sized to fit within one of the guides 132 of the chassis 102.

In certain implementations, the chassis 102 may include a plurality of pairs of opposing guides 132. Each of the pairs of opposing guides 132. is configured to receive the rails 128 of a respective tray arrangement 120 to enable the tray arrangement 120 to glide along the guides 132 between the retracted and extended positions. In certain implementations, the tray arrangement 120 can be inserted into and/or removed from the chassis 102. by sliding the tray arrangement along the guides 132,

In certain implementations, the tray arrangement 120 is releasably lockable relative to the chassis 102 to retain the tray arrangement 120 in at least one position. In certain examples, the tray arrangement 120 is releasably lockable relati ve to the chassis 102 in multiple positions (c.g . the retracted position and the extended position). In certain implementations, the tray arrangement 120 carries a latching arrangement 140 including a stop member 142, 144 configured to releasably engage a catch surface 137, 139 of the chassis 102. In certain implementations, the latching arrangement 140 is configured to be actuated by movement of the cable guide 126 relative to the chassis 102.

In certain implementations, the chassis 102 defines a catch surface corresponding to each lockable position of the tray arrangement 120. In certain examples, the chassis 102 defines a front catch surface 137 and a rear catch surface 139. In certain examples, the front catch surface 137 faces rearward and the rear catch surface 139 faces forward. In certain implementations, each catch surface 137, 139 is offset from a respective guide 132 along the height H of the chassis 102. In certain examples, each catch surface 137, 139 is continuous with the guide 132. In the example shown, each catch surface 137, 139 extends upwardly and downwardly from the respective guide 132 to form a respective pocket 136, 138 along the guide 132.

In certain implementations, the latching arrangement 140 includes a first stop member 142 and a second stop member 144. Each stop member 142, 144 is moveable between a latch position and a release position. In certain examples, each stop member 142, 144 is biased to the latch position. In certain implementations, the first and second stop members 142, 144 align with corresponding apertures 146, 148 defined through the tray of the tray arrangement 120. The stop members 142, 144 extend through the corresponding apertures 146, 148 when biased to the latch positions (e.g., see FIG. 5). Accordingly, each stop member 142, 144 automatically engages the front catch surface 137 through the respective aperture 146, 148 when aligned with the pocket 136.

In certain implementations, the latching arrangement 140 includes a first deflection member 150 and a second deflection member 160. Both the first deflection member 150 and the second deflection member 160 are carried by the respective tray arrangement 120 relative to the chassis 102. The first deflection member 150 defines the cable guide 126. The second deflection member 160 defines a stop member (e.g., the second stop member 144). in some implementations, the second deflection member 160 also defines the first stop member 142. In other implementations, the first deflection member 150 defines the first stop member 142.

The first deflection member 150 is configured to be manually moved by a user against a biasing force to move the first stop member 142 from tire latch position to the release position. The second deflection member 160 is configured to be manually moved by a user against a biasing force to move the second stop member 144 from the latch position to the release position, in certain examples, a common biasing member 145 provides the biasing force to both the first deflection member 150 and the second deflection member 160. In certain examples, the biasing member 145 includes a leaf spring. In some examples, the first deflection member 150 defines the biasing member 145. In other examples, the second deflection member 160 defines the biasing member 145.

In use, the first stop member 142 of the latching arrangement 140 inhibits forward movement of the tray arrangement 120 relative to the chassis 102 when the tray arrangement 120 is disposed in the retracted position within the chassis 102. In particular, the first stop member 142 engages a respective rearward-facing first catch surface 137 defined at the first pocket 136. in certain examples, the first stop member 142 also may- engage a forward-facing third catch surface 133 disposed in the same pocket 136 as the first catch-surface 137. Engagement between the first stop member 142 and the third catch surface 133 inhibits rearward movement of the tray arrangement 120 relative to the chassis 102. In certain examples, the second stop member 144 engages a respective forward-facing second catch surface 139 at the second pocket 138 when the tray arrangement 120 is disposed in the retracted position to inhibit rearward movement of the tray arrangement 120 relative to the chassis 102.

To move the tray arrangement 12.0 to the extended position, the first deflection member 150 of the latching arrangement 140 is actuated to move the first stop member 142 to the release position so that the first stop member 142 no longer engages the first catch surface 137. Accordingly, the tray arrangement 120 can be moved forwardly relative to the chassis 102. In certain implementations, the sidewalls 134 of the chassis 102. define ramps 135 along which the second stop member 144 cams to move the second stop member 144 to the release position as the tray arrangement 120 is moved forwardly towards the extended position. When the tray arrangement 120 is disposed in the extended position, the second stop member 144 aligns with the pocket 136 and snaps into engagement with the first catch surface 137 to inhibit further forward movement. The second stop member 144 also may engage the third catch surface 133 to inhibit rearward movement of the tray arrangement 120 back to the retracted position. In certain examples, the front stop member 142 does not engage the chassis 102 when the tray arrangement 120 is disposed in the extended position ,

To move the tray arrangement 120 from the extended position to the retracted position (or to remove the tray arrangement 120 from the chassis 102 through the front of the chassis 102), the second deflection member 160 of the latching arrangement 140 is actuated to move the second stop member 144 to the release position so that the second stop member 144 no longer engages the first and third catch surfaces 137, 133. With the second stop member 144 released, the tray 120 is freely slidable along the guides 132 either rearwardly back to the retracted position or forwardly out of the chassis 102.

In some implementations, a latching arrangement 140 is only disposed at one side of the tray arrangement 120 (i.e., near only one of the rails 128). in other implementations, each tray arrangement 120 carries a first latching arrangement 140 at the first side of the tray arrangement 120 and a second latching arrangement at the second side of the tray arrangement 120 (e.g., see FIG. 5). in some examples, the second latching arrangement is identical to the first latching arrangement, in such examples, the actuation of the first and second stop members 142, 144 discussed above is performed on both latching arrangements simultaneously to move the tray arrangement 120. In other examples, the second latching arrangement includes the second stop member 144, but not the first stop member 142. In such examples, only the first latching arrangement 140 is actuated to move the tray arrangement 120 from the retracted position to the extended position, but both latching arrangements are actuated to move the tray arrangement 120 from the extended position.

Referring to FIGS. 7-10, the first deflection member 150 includes a base

152 at which the first deflection member 150 is pivotally mounted to the tray 121 of the tray arrangement 120 about a pivot axis P (e.g., see FIG. 9). In certain implementations, the base 152 is disposed at an opposite end of the first deflection member 150 from the cable guide 12.6. For example, a beam 154 may extend between the base 152 and the cable guide 126. in certain examples, the beam 154 is rigid so that the cable guide 126 is movable about the pivot axis P between a neutral position (e.g., see FIG. 5) and an actuated position (e.g., see FIG. 8). The cable guide 126 moves along an angle θ in a deflection direction D1 between the neutral and actuated positions to actuate the first deflection member 150. in certain examples, the cable guide 126 moves inwardly along the deflection direction D1 towards the opposite side of the tray 121 when moved from the neutral position to the actuated position (e.g., see FIG. 8).

The second deflection member 160 includes a base 162 at which the second deflection member 160 is pivotally mounted to the tray 12.1 of the tray arrangement 120 about the pivot axis P. The base 162 of the second deflection member 160 aligns with the base 152 of the first deflection member 150 along the pivot axis P. The second deflection member 160 includes a beam 164 extending outwardly from the base 162 to a free end 165 carrying the second stop member 144. in certain examples, the beam 164 is rigid so that the second stop member 144 is carried between the latch position (e.g., see FIG. 9) and the release position (e.g., see FIG. 10) when the second deflection member 160 pivots about the pivot axis P. The second deflection member 160 also includes an actuation leg 166 extending outwardly from the base 162 to an end 168 opposite the free end 165. The second deflection member 160 is configured to pivot about the pivot axis P when the actuation leg 166 is manipulated by a user.

In some examples, the second deflection member 160 defines the first stop member 142 and the biasing member 145 (e.g., see FIGS. 7-10). In other examples, the first deflection member 150 defines the first stop member 142 and the second deflection member 160 defines the biasing member 145 (e.g., see FIGS. 11-14). In other examples, the first deflection member 150 defines the first stop member 142 and the biasing member 145 (e.g., see FIGS. 17-21). Four example implementations of the first deflection member 150a, 150b, 150c, 150d and the second deflection member 160a, 160b, 160c, 160d are shown herein in FIGS. 7-2.1.

Referring to FIGS. 7-10, a first implementation 160a of the second deflection member 160 defines the first stop member 142 tow ards the end 168 of the actuation leg 166. The actuation leg 166 is configured so that the first stop member 142 does not pivot with the second stop member 144. Rather, the actuation leg 166 is configured to that the first stop member 142 is entrained by the first deflection member 150a. For example, the end 168 of the actuation leg 166 may fit into a notch 156 defined in a first implementation 150a of the first deflection member 150. in the example shown, the notch 156 is defined at one end of the cable guide 126 so that the first end 168 of the actuation leg 166 moves in unison with the cable guide 126 as the cable guide 126 is pivoted between the neutral and actuated positions. Accordingly, actuating the first deflection member 150a moves the first stop member 142 to the release position.

In certain implementations, the actuation leg 166 defines the biasing member 145. Accordingly, the actuation leg 166 biases the first stop member 142. to the latch position. Because the actuation leg 166 is entrained with the cable guide 126, the actuation leg 166 also biases the cable guide 126 to the neutral position. Accordingly, when the cable guide 126 is released by the user, the actuation leg 166 biases the first stop member 142 back to the latch position. In the example shown, the biasing member 145 also biases the second stop member 144 to the latch position (e.g., see FIG. 9).

The second stop member 144 does not move when the cable guide 126 of the first deflection member 150a is actuated. Rather, the second stop member 144 moves when the actuation leg 166 of the second deflection member 160a is actuated. For example, deforming or deflecting the actuation leg 166 in a second deflection direction D2 moves the second stop member 144 from the latch position to the release position. In the example shown in FIG. 10, the second deflection direction D2. extends opposite the first deflection direction D1 (FIG. 8). Accordingly, a user presses the actuation leg 166 outwardly towards the closest rail 128 of the tray arrangement 120 to actuate the second deflection member 160a, thereby moving the second stop member 144 to the release position. Because the actuation leg 166 defines the biasing member 145, releasing the actuation leg 166 causes the second stop member 144 to transition back to the latch position.

Referring to FIGS, 11-14, a second implementation 150b of the first deflection member 150 carries the first stop member 142, In certain implementations, the first stop member 142 moves in unison with the first deflection member 150a as the first deflection member 150a pivots between the neutral and actuated positions. In certain examples, the first stop member 144 is disposed along the beam 154 between the cable guide 126 and the base 152. In the example shown, the first stop member 144 is disposed closer to the cable guide 126 than to the base 152.

The actuation leg 166 of a second implementation 160b of the second deflection member 160 defines the biasing member 145. However, the end 168 of the actuation leg 166 is not entrained with the first deflection member 150b. Rather, the end 168 of the actuation leg 166 abuts the beam 154 of the first deflection member 150b to bias the first deflection member 150b to the neutral position, in certain examples, the first deflection member 150b includes a tensioner 155 about which the end 168 of the actuation leg 166 curls. The tensioner 155 pre-tensions the biasing member 145.

The first deflection member 150b is actuated as discussed above by deflecting the cable guide 126. The second deflection member 160b is actuated as discussed above by pressing the actuation leg 166 in the second deflection direction D2 towards the closest rail 128 of the tray arrangement 120 (e.g., compare FIGS. 13 and 14). In certain examples, the actuation leg 166 defines an indicator 147 (e.g., textured surface such as bumps or ridges, textual indicia, printed symbol, color-coded region, etc.) that identifies a region of the actuation leg 166 to press to actuate the second deflection member 160b. in the example shown, the actuation leg 166 defines a leaf spring biasing member 145 having a concave curvature so that an intermediate portion of the actuation leg 166 curves towards the closest rail 128.

FIGS. 15-16 show example implementations 150c, 160c of the first and second deflection members 150, 160 where the actuation leg 166 of the second deflection member 160 has a convex shape before actuation (e.g., see FIG, 15). Pressing on the actuation leg 166 deflects the biasing member 145 into having a concave shape (e.g., see FIG. 16). The concave shape may increase the deflection distance for the actuation leg 166, which may provide a greater lateral distance between the latch and release positions of the second stop member 144.

FIGS. 15 and 16 also illustrate the latching arrangement 140 disposed at an opposite side of file tray arrangement 120 than what is shown in FIGS. 7-14. Accordingly, the second deflection direction D2 shown in FIG. 16 faces in the opposite direction than what is shown in FIG. 14. However, in both FIGS. 14 and 16, the second deflection direction D2 extends towards the nearest rail 128 of the tray arrangement 120 (i.e., towards an exterior of the tray arrangement instead of towards an interior of the tray arrangement). Accordingly, if both latching arrangements 140 of the tray arrangement 120 include the first stop member 142, then the cable guide 126 shown in FIG. 15 would deflect inwardly in the first deflection direction Dl. Alternatively, if the latching arrangement shown in FIGS. 15 and 16 does not include a first stop member, then the cable guide 126 may be stationary relative to the tray arrangement 120. FIGS. 17-21 illustrate fourth example implementations I5Qd, 160d of first and second deflection members 150, 160. The first deflection member 150d carries the first stop member 142. and defines the biasing member 145. For example, the first stop member 142 is disposed along the beam 154 between the base 152 and the cable guide 126. The biasing member 145 extends outwardly from the base 152 opposite the beam 154. in certain examples, the biasing member 145 includes a leaf spring. The first deflection member I50d is actuated by deflecting the cable guide 126 inwardly as discussed above.

The second deflection member 160d includes a rigid actuation leg 166 extending outwardly from the base 162 opposite the beam 164 carrying the second stop member 144. Pressing on the end 168 of the actuation leg 166 causes die second deflection member 160d to rotate about the base 162, which moves the second stop member 144 from the latch position (e.g., see FIG. 20} to the release position (e.g., see FIG. 2.1). In certain examples, an indicator 147 (e.g., a raised arrow, a textures surface, a colored section, textual indicia, etc.) is disposed at the end 168 of the actuation leg 166 to indicate to a user where to press to actuate the second deflection member 160d. In certain examples, the beam 154 of the first deflection member 150d defines a notch 157 aligned with the indicator 147 to facilitate finger access to the second end 168 of the second deflection member 160d.

In certain implementations, the beam 164 of the second deflection member 160d has a surface 161 against which the biasing member 145 presses to hold the second stop member 144 in the latch position. In certain examples, the biasing member 145 also holds the first deflection member 150d in the neutral position through engagement which the surface 161. in certain implementations, the second deflection member 160d defines an abutment wall 167 that extends downwardly from the actoation leg 166, Engagement between the abutment wall 167 and the beam 154 of the first deflection member 150d inhibits continued rotation of the second deflection member 160d after the second stop member 144 reaches the release position.

FIGS. 22-26 illustrate another example latching arrangement 170 including a stop member 172 that is movable between a latch position and a release position. The latching arrangement 170 is actuated (e.g., the stop member 172 is moved between the latch and release positions) by movement of a cable guide 126 relative to the tray arrangement 120. In certain examples, the cable guide 126 is movable along the forward- rearward axis FR relative to the tray arrangement 120. Accordingly, the tray arrangement 120 can be moved from the retracted position to the extended position by pulling forwardly on the cable guide 126 until the stop member 172 transitions to the release position and continuing to pull on the cable guide 126 until the tray arrangement 120 slides along the chassis 102 to the extended position. Similarly, the tray arrangement 120 can be moved from the extended position back to the retracted position by pushing rearward on the cable guide 126 until the stop member 172 transitions to the release position and continuing to push on the cable guide 126 until the tray arrangement 120 slides along the chassis 102 to the retracted position.

In certain implementations, the chassis 102 includes sidewalls 134’ that define protruding guides 132' instead of the channel guides 132 of FIG. 4. in such implementations, the latching arrangement 170 includes a body 174 defining a channel 176 that receives one of the guides 132’. In certain examples, the channel 176 and guides 132’ may he shaped to fit together (e.g., with a dovetail). The body 174 is secured to the tray arrangement 120 to move in unison with the tray arrangement 120. Accordingly, the tray arrangement 120 slides along the chassis 102 by gliding over one of the guides 132’. In certain examples, the chassis 102 defines multiple pairs of guides 132’ and each pair of guides 132’ is configured to support a respective tray arrangement 120.

In certain implementations, the guides 132’ define one or more pockets 136, 138 sized to receive the stop member 172. In certain examples, each guide 132’ defines a forward pocket 136 and a rearward pocket 138. In the example shown, the rearward pocket 138 is longer than the forward pocket 136. In other examples, the forward and rearward pockets 136, 138 are a common size, in other examples, the each guide 132’ defines only the rearward pocket 138. When the tray arrangement 120 is disposed in the retracted position, the stop member 172 is disposed in the rearward pocket 138.

In some implementations, the stop member 172 is disposed in the forward pocket 136 when the tray arrangement 120 is disposed in the extended position. In other implementations, the stop member 172 abuts against an edge 131 of the guide 132’ when the tray arrangement 120 is disposed in the extended position. In certain implementations, the tray arrangement 120 is configured to latch to the chassis 102 in either of two extended positions. In the example shown, the stop member 172. engages the forward pocket 136 when the tray arrangement 120 is disposed in the first extended position and the stop member 172 abuts the edge 131 of the guide 132’ when the tray arrangement 120 is disposed in the second extended position. in certain implementations, travel between the latching arrangement body 174 and the guide 132’ is limited. For example, the body 174 may include a limiter 173 extending outwardly from the body 174. in certain examples, the limiter 173 protrudes through the channel 176 defined by the body 174 (e.g., see FIG. 23). The limiter 173 rides along the elongate rearward pocket 138 as the tray arrangement 120 is slid relative to the chassis 102. When the tray arrangement 120 is disposed in the retracted position, the limiter 173 is disposed at a rearward edge of the elongate pocket 138. When the tray arrangement 120 is disposed in an extended position, the limiter 173 is disposed at a forward edge of the elongate pocket 138. in certain examples, the limiter 173 is configured to be manually retracted from the rearward pocket 138 to remove the tray- arrangement 120 from the chassis 102 (e.g., through the front 104).

In accordance with certain aspects of the disclosure, the latching arrangement 170 includes a deflection arrangement 180 and an actuation member 190.

The deflection arrangement 180 includes the stop member 172. The actuation member 190 includes the cable guide 126. The actuation member 190 is movable (e.g., slidable) relative to the deflection arrangement 180. In certain implementations, the cable guide 126 is movable along the forward-rearward axis while the stop member 172 is movable along an axis S that is trans verse to the forward-rearward axis FR.

In certain implementations, the deflection arrangement 180 is a bistable mechanism including a shuttle 185 that is movable relative to a first base 181 and a second base 189 along the axis 8. The shuttle 185 carries the stop member 172 between the latch position (e.g., see FIG. 23) and the release position (e.g., see FIG. 24). The shuttle 185 is coupled to the first and second bases 181. 189 by arms 182. The first and second bases 181, 189 are fixed relative to each other. One end of each arm 182 couples to the shutle

185 at a first flexural pivot 184 and the other end of each arm 182 couples to the respective base 181, 189 at a second flexural pivot 186,

The bases 181, 189 are positioned sufficiently close together to cause the arms 182 to bow outward. Accordingly, absent external forces, the flexural pivots 184,

186 cooperate to hold the shuttle 185 in one of two stable positions — a first flexed position

(e.g., see FIG. 24A) and a second flexed position (not shown) in which the arms 182. bow in an opposite direction. When the shuttle 185 is disposed in either flexed position, the shuttle 185 will not move absent external forces, if an external force is applied to shift the shuttle 185 along the axis S (e.g., see FIG. 24B), then the amis 182 will bias the shutle 185 towards the nearest of the two stable positions. Accordingly, the arms 182 bias the shuttle 185 in a first direction along the axis S until the shuttle 185 passes over a centerline upon which the amis 182 bias the shuttle 185 in an opposite second direction along the axis S.

The stop member 172 is disposed in the latch position when the shuttle 185 is disposed in the first flexed position. In certain implementations, the release position of the stop member 172 is not one of the stable positions of the deflection arrangement 180. Rather, the stop member 172 is held in the release position by the actuation member 190 as will be described herein. In certain examples, the release position is located between the first flexed position and the centerline.

In the example shown in FIGS. 24A and 24B, the shuttle 185 is coupled to each base 181, 189 by two amis 182. In other examples, however, the shuttle 185 may be coupled to each base 181, 189 by a greater or lesser number (e.g., three, one, etc.) number of arms 182. In certain examples, one or more of the arms 182 may carry a earn follower 188 at an intermediate location between the first and second flexural pivots 184, 186. in the example shown, a first ami 182 extending between the shuttle 185 and the first base 181 carries a first earn follower 188 and a second ann 182 extending between the shuttle 185 and the second base 189 carries a second cam follower 188.

As shown in FIGS. 25 and 26, the actuation member 190 is slidable along the forward-rearward axis FR between a neutral position NP (e.g., FIG. 25) and an actuated position AP (e.g., FIG. 26). In certain examples, the actuation member 190 slides a distance M between the two positions NP, AP. The actuation member 190 includes a body 192 that defines a camming surface 194 for each cam follower 188 of the deflection arrangement 180. When the body 192 of the actuation member 190 slides along the forward-rearward axis FR, each cam follower 188 rides along the respective camming surface 194 to shift the cam follower 188 along the axis S against the bias of the deflection arrangement 180. Shifting the cam followers 188 deflects die respective amis 182, which translates the shuttle 185 along the axis S.

In certain examples, the camming surfaces 194 are V-shaped. The cam followers 188 are disposed at a center of the V -shape when disposed in the neutral position. The cam followers 188 move over a first half of the V-shape of the respective camming surface 194 when the actuation body 192 is pulled in a first direction (e.g., forward) along the forward-rearward axis FR and move over a second-half of the V-shape of the respective camming surface 194 when the actuation body 192 is pushed in an opposite second direction (e.g., rearward) along the forward-rearward axis FR. Accordingly, the stop member 172 can be transitioned away from the latch position by either pushing or pulling on the actuation member 190 (e.g., on the cable guide 126).

In certain implementations, the deflection arrangement 180 and actuation member 190 are configured to inhibit the shuttle 185 from reaching the second stable position when the shuttle 185 is moved along the axis S away from the first stable position. For example, the actuation member 190 includes a limiter wall 193 against which the shuttle 185 abuts when entrained by the camming members 188 away from the first flexed position. Engagement between the shuttle 185 and the limiter wall 193 inhibits the shuttle 185 from crossing the centerline. Accordingly, the arms 182 will bias the shuttle 185 (and hence the stop member 172) back towards the first flexed (latched) position.

When the tray arrangement 120 reaches one of the discrete positions (e.g., the retracted position, the extended position, etc.), the user releases the actuation member 190. Without the force applied by the user to counteract the bias of the deflection arrangement 180, the shuttle 185 (and hence stop member 172) translates back towards the stable position (the latch position). Therefore, the stop member 172 will snap into the pocket 136, 138 or over the edge 131 upon reaching one of the discrete positions of the tray arrangement 120. Further, the translation movement of the camming members 188 back along the axis S pushes (via camming surfaces 194) the actuation member 190 back towards the neutral position.

Referring now to FIGS. 27-32, the tray arrangement 120 can be equipped with various types of cable management to route cables towards and away from the tray arrangement 120. For example, one or more cable guides 126 can be disposed at a front of the tray arrangement 120 while one or more rear cable guides 12.7 are disposed at a rear of the tray arrangement 120. In the example shown, the cable guides 126 are oriented to define through-passages T transverse to the forward-rearward axis FR and the rear cable guides 127 are oriented to define passages R extending along the forward-rearward axis FR. In certain implementations, the cable guides 126 are disposed along the front of the tray arrangement 120 in alignment with cassette guides G (see FIG. 5). In certain implementations, the cable guides 126 are disposed between finger access openings 123 defined through the tray arrangement 120 at the front. In the example shown in FIG. 27, the tray arrangement 120 defines two cable guides 126 disposed between three finger access openings 123 so that each cable guide 126 is disposed between an adjacent pair of the finger access openings 123 , In certain examples, the latching arrangemeiit(s) 140 mounted to the tray arrangement 120 add cable guides 126 to the opposite sides of the tray arrangement 120 (e.g., see FIG. 5) in addition to the cable guides 126 shown in FIG. 27.

In some implementations, a rear cable guide 127 is provided for each rear finger access opening 125 is defined at the rear of the tray arrangement 120. In other implementations, a greater or lesser number of rear cable guides 127 are provided on the tray arrangement 120. For example, FIG. 32 shows a single rear cable guide 127 mounted to the tray arrangement 120. In the example shown in FIG. 32, the rear cable guide 127 is mounted to a central portion of the rear of the tray arrangement 120.

In certain implementations, the various types of cable guides 126, 127 not forming past of the latching arrangement 140, 170 can be magnetically mounted to the tray arrangement 120. For example, FIGS. 28 and 29 show an example implementation 200 of a cable guide 126 suitable for mounting at the front of the tray arrangement 120. lire cable guide 200 includes a guide body 2.02 and a magnet 2.04 coupled to the guide body 202. The magnet 204 is configured to be magnetically attracted to the tray arrangement 120 (e.g., to the tray 121).

The magnet 204 is mounted within a base 206 of the guide body 202. For example, the magnet 204 can be disposed within a cavity 210 defined in the base 2.06 and accessible from a bottom of the guide body 202. In some examples, the magnet 204 is adhesively coupled within the cavity 210. In other examples, the magnet 204 may be friction fit, latched, enclosed, or otherwise secured within the cavity 2.10.

A passage-defining member 208 extends outwardly from the base 206 to define the through-passage T. The base 206 defines a bend radius limiting surface 205 forming part of the through-passage T. The passage-defining member 208 includes a bottom wall 212 and an end wall 2.14 coupled to the bottom wall 212 opposite the base

206. The bottom wall 212 is longer than the end wall 214 is tall so that the through - passage T is elongate along the forward-rearward axis FR. The passage-defining member 208 also may include a top wall 216. in certain examples, the top wall 216 is slit to enable one or more fibers or cables to enter the passage T through the slit instead of being threaded through the passage T.

In certain implementations, the guide body 202 is configured to mate with the tray arrangement 120 to assist in holding the guide body 202 to the tray arrangement 120. In certain examples, the guide body 2.02 defines a bottom recess 220 extending along the forward-rearward axis FR between a forward-facing wall 222 and a rearward-facing wall 224. The guide body 202 can be mounted so that the forward-facing wall 222 extends into one of the finger access openings 123 and the rearward-facing wall 224 extends over a front edge of the tray arrangement 120. In certain examples, the guide body 202 defines a further notch or groove 226 within the bottom recess 220 to accommodate a raised front flange 228 (FIG. 27) at the front edge of the tray arrangement 120.

FIGS. 30 and 31 show an example implementation 230 of a rear cable guide 127 suitable for mounting at the rear of the tray arrangement 120. The rear cable guide 230 includes a guide body 232. and one or more magnets coupled to the guide body 232. The one or more magnets are configured to be magnetically attracted to the tray arrangement 120 (e.g., to the tray 121). In the example shown, the guide body 232 defines a through-passage R extending between opposite first and second bases 2.36. Each base 236 defines a cavity 240 in which one of the magnets can be mounted (e.g., adhesively, frictioiia.il y, etc.). Tire bases 236 define opposing bend radius limiting surfaces 235 that form part of the through-passage R .

The bases 236 are coupled together by a bottom wall 242. in certain examples, a top wall 2.46 extends from the first base 2.36 towards the second base 2.36. In some examples, a single top wall 246 connects the bases 236. In other examples, a, respective top wall 246 extends from each base 236 so that ends of the top walls 246 oppose each other to define a lateral slit through which the through-passage R is accessible.

In certain examples, the rear cable guide 230 includes flanges 254 extending outwardly from the bases 2.36. The flanges 254 may facilitate mounting the rear cable guides 230 (e.g., a user may press on the flanges 254 to mount the guide 230 to the tray arrangement 120). Tire flanges 254 also may aid in routing cables around the rear cable guides 230. The flanges 254 also may aid in handing the rear cable guides 230 during installation.

In some implementations, the cable guides 126, 12.7 are mountable at any position along the tray arrangement 120. in other implementations, the cable guides 126, 127 are mountable at pre-determined positions along the tray arrangement 120. For example, the cable guides 126, 127 and the tray arrangement 120 may cooperate to form an alignment arrangement to position the cable guides 12.6, 127 at the predetermined positions. For example, the rear cable guide 230 shown in FIGS. 30 and 31 includes alignment pegs 250 that fit within alignment holes 252 (e.g., see FIG. 32) defined by the tray ⁷ arrangement 120,

FIG. 33 shows another implementation 260 of the cable management guide 126 configured to be mounted to the tray arrangement 120 (e.g., at a front edge of the tray arrangement 12.0). The guide 260 is substantially similar to the cable guide 126 shown in FIGS, 28 and 29, except the guide 260 includes alignment pegs 262 that fit into alignment holes 234 to help position the guide 260.

FIGS. 34-43 illustrate four alternative implementations 270, 290, 300, 304 of the cable management guide 126 configured to be mounted to the tray arrangement 120 without a magnet. Each of the cable guides 270, 290, 300, 304 is configured to mount to a front strip 268 defining a front edge of the tray arrangement 120. A first alternative guide 270 is shown in FIGS. 35 and 36. A second alternative guide 290 is shown in FIGS. 37 and 38, A third alternative guide 300 is shown in FIG. 39, A fourth alternative guide 304 is shown in FIGS. 40-43.

Each of the cable guides 270 includes a guide body 272 having a passage- defining section 278 extending outwardly from a mounting section 276 to define the through-passage T. The mounting section 276 defines a slot 274 extending parallel to the through-passage T. The slot 274 is sized to receive the front strip 268 of the tray arrangement 120. The slot 274 is partially defined by opposing retaining tabs 273, 275. The passage-defining section 278 of each cable guide 270, 290, 300, 304 is about the same, but the mounting sections 276 differ from each other.

FIGS. 35-36 illustrate a first non-magnetic cable guide 270 where the mounting section 276 includes a release member 280 attached to the passage -defining section 278 by a web 282. Accordingly, the release member 280 is configured to flex or pivot relative to the passage-defining section 278 to change the shape of the slot 274. For example, atop 284 of the release member 280 can be deflected towards the passage- defining section 278 to move a bottom 285 of the release member 280, which includes the retaining tab 275, away from the passage-defining section 278 to enlarge the slot 274. In an example, the passage-defining section 278 may define a grip member 286 to enable a user to pinch the top 284 of the release member 280 towards the grip member 286 to enlarge the slot 274. In certain examples, the release member 280 defines a slot 288 in which a tool (e.g,, a screw driver, part of a tweezer, etc.) can be inserted to aid in deflecting the release member 280. in certain examples, the front strip 268 defines a notch 269 (e.g., a forwardly-facing notch) at which the first non-magnetic cable guide 270 can mount. If the cable guide 270 is sized to mount at the notch 269, then the cable guide 270 w'ould not be able to slide along the front strip 268. Rather, the sides of the notch 269 w'ould retain the cable guide 270 in position.

FIGS. 37 and 38 illustrate a second non-magnetic cable guide 290, which includes a release member 292 defining the second retaining tab 275. The release member 292 is configured to flex along an axis A (e.g., transverse to the through-passage T) to enlarge the slot 174. In certain examples, tire release member 292 has an accordion shape to enable movement of the second retaining tab 275 away from the first retaining tab 273 of the passage -defining section 278 along the axis A. In certain implementations, the second non-magnetic cable guide 290 can be mounted at a notch 269 in the front strip 268 to inhibit lateral movement of the cable guide 290 along the front strip 268.

FIG. 39 illustrates a third non-magnetic cable guide 300, which includes a release member 302 defining the second retaining tab 275. The release member 302 includes a flexible arm cantilevered from the passage -defining section 278. The release member 302 curves so that deflection of the release arm 302 moves the second retaining tab 275 axially relative to the first retaining tab 273, thereby allowing a user to enlarge the slot 274 to assist in mounting the cable guide 300. In certain implementations, the third non-magnetic cable guide 300 can be mounted at a notch 269 in the front strip 268 to inhibit lateral movement of the cable guide 300 along the front strip 268.

FIGS. 40-43 illustrate a fourth non-magnetic cable guide 304, which has a mounting section 276 that does not include a movable component. Rather, the mounting section 2.76 includes a mounting member arrangement 305 that is configured to be secured to the front strip 268 of the tray arrangement 120 through a twisting action. By not including moving or flexible components, the cable guide 304 may be more stable and less likely to break.

In certain implementations, the mounting section 276 defines a flat bottom surface 306 extending between a ramped wall 316 and a wedge member 314. in certain examples, the wedge member 314 does not extend fully across a width of the mounting section 276 to facilitate the twisting motion for mounting the cable guide 304. in certain implementations, the mounting member arrangement 305 includes a first foot 308, a second foot 310, and an alignment peg 312. In certain examples, the first foot 308, the second foot 310, and the alignment peg 312 are aligned across the width of the mounting section 276. In certain examples, the alignment peg 312 is disposed between the first and second foot 308, 310. In certain examples, the first foot 308 faces in an opposite direction to the second foot 310.

As shown in FIG. 41, the front strip 268 of the tray arrangement 120 defines a first aperture 309 configured to receive the first foot 308, a second aperture 311 configured to receive the second foot 310, and a third aperture 313 configured to receive the alignment peg 312. in certain examples, the first aperture 309 is offset from the second aperture 311 along the forward-rearward axis FR. As shown in FIG. 42, the cable guide 304 is mounted to the strip 268 by first inserting the first foot 308 into the first aperture 309 and the alignment peg 312 into the third aperture 313. Because the first and second apertures 309, 311 are offset and the first and second feet 308, 310 are not, the cable guide 304 is tilted along a longitudinal axis of the cable guide 304 (which extends parallel to the forward-rearward axis FR of the tray arrangement 120) to enable insertion of the first foot 308 into the first aperture 309. Hie shapes of the ramped wall 316 and wedge member 314 accommodate this tilting.

As the cable guide 304 is untilted, the cable guide 304 is twisted about an axis extending parallel to the height H of the chassis 102. Twisting the cable guide 304 aligns the second foot 310 with the second aperture 311 to allow the second foot 310 to be inserted into the second aperture 311 as the cable guide 304 is untilted. The first and second apertures 309, 311 are sized to accommodate movement of the feet 308, 310 within the apertures 309, 311 during the twisting motion. In certain examples, the alignment peg

312 and third aperture 313 are rounded to accommodate the twisting motion. As shown in

FIG. 43, when the second foot 310 is fully inserted into the aperture 311, the cable guide

304 cau be twisted back until the feet 308, 310 abut oppositely-facing sides of the respective apertures 309, 311. The feet 308, 310 hold the cable guide 304 to the tray arrangement 120.

FIGS. 44-52 illustrate another example tray latching arrangement 320 including first and second stop members 322, 324 that are each movable between a latch position and a release position. The latching arrangement 320 is actuated (e.g., one of the stop members 322, 324 is moved from the latch position to the release position) by movement of a cable guide 326 relative to the tray arrangement 120. In certain examples, the cable guide 326 is movable along the forward-rearward axis FR relative to the tray arrangement 120. in some implementations, first and second tray latching arrangements 320 are disposed at opposite sides of the tray arrangement 120. In other implementations, only one side of the tray arrangement 120 has a tray latching arrangement 320.

Each tray arrangement 120 is moved from the retracted position to the extended position by pulling forwardly on the cable guide 326 until the first stop member 32.2 transitions to the release position and continuing to pull on the cable guide 326 until the tray arrangement 120 slides along the chassis 102 to the extended position. Similarly, the tray arrangement 120 can be moved from the extended position back to the retracted position by pushing rearward on the cable guide 326 until the second stop member 324 transitions to the release position and continuing to push on the cable guide 32.6 until the tray arrangement 120 slides along the chassis 102 to the retracted position.

In certain examples, each stop member 322, 324 is biased to the latch position. In certain implementations, the first and second stop members 32.2, 324 align with corresponding apertures 146, 148 defined through the tray of the tray arrangement 120. The stop members 322, 324 extend through the corresponding apertures 146, 148 when biased to the latch positions (e.g., see FIG. 49). Accordingly, each stop member 322, 324 automatically engages a chassis catch surface 137, 366 through the respective aperture 146, 148 when in the retracted position.

As shown in FIG. 45, each latching arrangement 320 includes a biasing member 330 having a mounting section 334 fixedly coupled to the tray arrangement 120 and an actuation member 332 slidably mounted to the tray arrangement 120. The actuation member 332 is configured to slide relative to the biasing member 330. in certain implementations, the actuation member 332 slides along a length LB of tire biasing member 330 between a neutral position, a first actuated position, and a second actuated position. In certain examples, the neutral position is disposed between the first and second actuated positions along the length LB of the biasing member 330.

As shown in FIG. 46, the biasing member 330 includes a first arm 336 extending outwardly from the mounting section 334 in a first direction and a second arm 338 extending outwardly from the mounting section 334 in a generally opposite second direction. The first and second arms 336, 338 are deflectable relative to the mounting section 334. The first stop member 322 is defined or carried at the free end of the first ami 336 to deflect relative to the mounting section 334 and die second stop member 324 is defined or carried at the free end of the second arm 338 to deflect relative to the mounting section 334. Each of the arms 336, 338 defines a ramped portion 340, 342, respectively.

FIGS. 47-48 illustrate an example implementation of the actuation member 332. Hie actuation member 332 includes a body 344 that is elongate between opposite first and second ends 346, 348. The first end 346 of the actuation member body 344 defines the cable guide 326. in certain implementations, the actuation member body 344 defines an interior 350 in which the biasing member 330 may be disposed (see FIGS. 44 and 49). Hie actuation member body 344 defines a mounting section 352 that aligns with the mounting section 334 of the biasing member 330. The mounting section 352 defines an opening 354 that aligns with an opening 335 defined at the mounting section 334 of the biasing member 330. Accordingly, a screw or other fastener 356 may be inserted through both openings 354, 335 to attach both the actuation member 332 and the biasing member 330 to the tray arrangement 120.

FIG. 50 illustrates an interior sidewall 134 of the chassis 102 defining front and rear pockets 136, 374 disposed along guides 132. The front pocket 136 defines the rearwardly -facing catch surface 137. The rear pocket 374 defines a rearwardly-facing catch surface 366. The rear pocket 374 is about the same size as the front pocket 136. In certain implementations, the catch surface 137 of the front pocket 136 angles forwardly as die catch surface 137 extends outwardly away from the tray arrangement 120 (e.g., see FIG. 51). The angle of the catch surface 137 causes the first stop member 322 to extend further into the pocket 136 as the biasing member 330 is translated forwardly relative to the chassis 102, which further secures the latch. Accordingly, the angle of the catch surface 137 guards against accidental opening of the tray arrangement 120.

The actuation member 332 translates relative to the biasing member 330 along a translation axis T that extends parallel to the forward-rearward axis FR of the tray arrangement 120. The actuation member 332 translates from a neutral position to either a first actuation position that is forward of the neutral position or a second actuation position that is rearward of the neutral position. When the actuation member 332. is disposed in the neutral position, the first and second stop members 322, 324 align with and extend into the apertures 146, 148 and engage catch surface 137, 366 of the chassis 102 (e.g., see FIG.

50). Engagement between the first stop member 322 and the catch surface 137 inhibits forward movement of the tray arrangement 12.0 relative to the chassis 102.

The actuation member 332 carries a first actuator member 362 and a second actuator member 364 at opposite ends of the mounting section 352. The first and second actuator members 362, 364 align with the ramped portions 340, 342. of each asm 336, 338 of the biasing member 330 so that, when the actuator member 332 is disposed in the neutral position, the actuator members 362, 364 allow the arms 336, 338 to bias the stop members 322, 324 into engagement with the catch surfaces 137, 366 (e.g., see FIG. 50).

When a user wishes to pull out the tray arrangement 120 to the forward position (e.g., see FIG. 52), the user pulls on the cable guide 326 to translate the actuation member 332 along the translation axis T. During translation of the actuation member 332, the elongate opening 354 moves relative to the biasing member 330 until the fastener 356 abuts an edge of the elongate opening 354. The first actuator member 362 engages the ramped portion 340 of the first arm 336 to deflect the first aim 336 inwardly towards the tray arrangement 120 to move the first stop member 322 out of engagement with the first catch surface 137 (e.g., see FIG. 52). Continuing to pull on the cable guide 326 pulls the tray arrangement 120 forwardly relative to the chassis 102. The second stop member 324 cams over a catch surface 366 defined in the rear pocket 374. Accordingly, the second stop member 324 does not interfere with forward movement of the tray arrangement 120 from the retracted position to the extended position.

In certain implementations, the catch surface 366 extends rearwardly as the catch surface 366 extends outwardly away from the tray arrangement 120 (e.g., see FIG.

51). Engagement between the catch surface 366 and the second stop member 324 inhibits forward translation of the biasing member 330 relative to the chassis 102. Accordingly, when the actuation member 332 is initially translated forwardly to release the tray arrangement 120, the engagement between the second stop member 324 and the catch surface 366 resists translation of the biasing member 330 and thereby allows the first stop member 322 to be deflected out of the forward pocket instead of being pushed against the catch surface 137 and hence further into the forward pocket 136. The catch surface 366 is tingled so that continued pulling on actuation member 332 after the first stop member 322 is deflected out of engagement with the catch surface 137 causes the second stop member 324 to cam over the catch surface 366, thereby allowing the tray arrangement 120 to be pulled out of the chassis 102.

FIG. 53 shows the tray arrangement 120 disposed in the forwardly extended position relative to the chassis 102. When the user releases the cable guide 326, the biasing member 330 has sufficient biasing force to push the actuation member 332 back to the neutral position through camming action of the ramped portion 340 of the first arm 336 and the first actuator member 362. The second stop member 32.4 is biased into engagement with the first catch surface 137 by the second arm 338 of the biasing member 330. Engagement between the second stop member 324 and the first catch surface 137 inhibits rearward movement of the tray arrangement 120 back into the chassis 102.

To move the tray arrangement 120 back to the retracted position, a user pushes against the cable guide 326 to move the actuation member 332 along the translation axis T from the neutral position to the second actuation position (e.g., see FIG. 54). In the second actuation position, the second actuator member 364 pushes against tire ramped postion 342 of the second arm 338 to deflect the second arm 338 inwardly towards the tray arrangement 120 to move the second stop member 324 out of engagement with the first catch surface 137. Continuing to push on tire cable guide 326 pushes the tray arrangement 120 rearwardly relative to the chassis 102 until the first stop member 322 snaps into the chassis pocket defining the first catch surface 137. in certain implementations, the translation of the actuation member 332 is limited by interaction between the actuation member and the fastener 356 holding the actuation member 332 and biasing member 330 to the chassis. For example, in certain examples, the opening 354 is oblong and elongate compared to the opening 335. Accordingly, the actuation member 332 can translate relative to the biasing member 330 as the fastener 356 slides along the elongate opening 354. In certain examples, the opening 354 is defined at a recessed pocket 358 in the actuation member body 344 so that a head of the fastener 356 does not extend past a top of the actuation member 332. Rather, the head of the fastener 356 is accommodated in the pocket 358.

In certain implementations, the actuation member 332 also defines an elongate cavity 368 that receives a pem 370 extending upwardly from the tray arrangement 120. The pem 370 translates within the elongate cavity as the actuation member 332 slides relative to the tray 121. Accordingly, translation of the actuation member 332 is limited by the size of the cavity 368. In certain examples, a second pem 372 extends upwardly from the tray 121 to receive the fastener 356 to secure the fastener 356 to the tray arrangement 120.

In certain examples, the actuation member body 344 includes glide surfaces 360 that protrude downwardly from a bottom of the actuation member body 344 to provide a limited surface area on which the actuation member body 344 slides over the tray arrangement 120. Providing the glide surfaces 360 limits the friction acting against the actuation member body 344 during translation.

FIGS. 55-62 illustrate another example tray latching arrangement 420 including first and second stop members 422, 424 that are each movable between a latch position and a release position. The latching arrangement 420 is substantially the same as the tray latching arrangement 320 described above except where otherwise indicated. The tray latching arrangement 420 includes a biasing member 430 having a mounting section 434 fixedly coupled to the tray arrangement 120 and an actuation member 432 slidably mounted to the tray arrangement 120 along the forward -rearward axis FR. The tray latching arrangement 420 is actuated by movement of a cable guide 426 defined by the actuation member 432 relative to the tray arrangement 120.

The actuation member 432 includes a body that is elongate between opposite first and second ends. The first end of the actuation member body defines the cable guide 426. In certain implementations, the actuation member body defines an interior in which the biasing member 430 may be disposed. The actuation member body defines a mounting section 452 that aligns with the mounting section 434 of the biasing member 430. The mounting section 452 defines a slot that aligns with an opening defined at the mounting section 434 of the biasing member 430. Accordingly, a screw or other fastener may be inserted through both openings to attach both the actuation member 432 and the biasing member 430 to the tray arrangement 120, The slot is sufficiently large to accommodate movement of the actuation member 432 relative to the fastener. In certain examples, the fastener does not extend fully through the actuation member 432 so that an upper surface of the actuation member 432 is unbroken above tire mounting section 434 of the biasing member 430. In certain implementations, the actuation member 432 defines a slot 458 through which a fastener 456 extends to mount the actuation member 432 to the tray 120. in certain examples, the slot 458 and fastener 456 are offset (e.g., forwardly offset) from the biasing member 430. in certain examples, the offset slot 458 extends full a through a top surface of the actuation member 432.

In certain implementations, the cable guide 426 includes a contoured guide surface 428 that extends outwardly from the cable guide 426 to guide fibers passing through the cable guide 426 over part 118 of the door attachment structure. In certain examples, the guide surfaces 42.8 of the cable guides 426 at opposite sides of the tray 120 extend m opposite directions. The guide surfaces 428 inhibit fiber pinching between die tray 120 and the door attachment structure. In certain examples, the guide surface 428 curves downwardly towards a bottom of the chassis 102. In certain examples, a retention wall 429 extends upw ardly from a rear of the cable guide surface 428 to inhibit fiber from being pinched between the tray 120 and the chassis 102.

Referring to FIGS. 59-62, each stop member 422, 424 is configured to automatically engage a chassis catch surface 137, 366 (FIG. 50) through the respective tray aperture 146, 148 when in the latch positions. In certain implementations, each stop member 422, 424 includes an enlarged tip 423, 425, respectively, in certain examples, the enlarged tips 423, 425 are enlarged along a height of the chassis 102 compared to a remainder of the stop members 42.2, 424. In certain examples, the tips 42.3, 425 extend upwardly along the height relative to the stop members 422, 424 (e.g., see stop member 422 in FIG. 55). in certain examples, the tips 423, 425 extend both upwardly and downwardly along the height relative to the stop members 422, 424 (e.g., see stop member 424 in FIG. 55). Enlarging the tips 423, 425 inhibits the stop members 422, 424 from catching on the guides 132 before reaching a pocket 136, 138 of the chassis 102.

In some examples, the stop members 422, 424 extend outwardly from the biasing member 430 at a common angle. In other examples, the first stop members 422 and second stop members 424 extend outwardly from the biasing member 430 at different angles 427, 429, respectively. In certain examples, the angle 427 of the first stop member

422 is larger than the angle 429 of the second stop member 422. In certain examples, the first stop member 422 extends outwardly at an obtuse angle while the second stop member

422 extends outwardly at an acute angle. In certain examples, the angle 427 of the first stop member is between 80 degrees and 100 degrees while the angle 429 of the second angle is between 60 degrees and 85 degrees. In certain examples, the angle 427 of the first stop member is between 85 degrees and 95 degrees while the angle 429 of the second angle is between 65 degrees and 80 degrees. The more acute angle 429 of the second stop member 424 aids in retaining the second stop member 424 at the catch surface 366 until the latching arrangement 420 is actuated. Aspects of the Disclosure
