Description:
WIRE TO BOARD CONNECTOR

RELATED APPLICATIONS

[0001] This application claims the benefit of United States provisional application Serial No. 62/589,698 filed on November 22, 2017, the contents of which are incorporated herein in its entirety.

TECHNICAL FIELD

[0002] This disclosure relates to the field of electrical connectors, more specifically to electrical connectors suitable for use in wire to board applications.

DESCRIPTION OF REL ATED ART

[0003] Wire to board connectors are commonly used in applications where an electrical connection is made between a wire or cable assembly to a printed circuit board. Typical connections are made to a conductive contact pad formed on the edge of the circuit board, e.g., edge connectors, and usually engage the edge of the board in a sliding manner. In other instances, a connection is required on an internal portion of the circuit board. In these instances, a connector cannot be slidably engaged like an edge connector but rather are adapted to engage a pad or plated hole disposed at an internal location of the board.

[0004] Previous solutions involved mounting a connector to an internal portion of the board with an electrical connector having tails that w^ere soldered to either the plated through hole or contact pad. This connector provided an attachment point for another connector secured to a wire or cable assembly to be connected to the circuit board. Certain individuals, however, would appreciate further improvements to wire to board connections.

SUMMARY

[0005] In an embodiment of the disclosure, a wire to board connector is shown and includes a plurality of conductive terminals which are mounted in a non-conductive cover, and the cover is hingedly attached to a base which is configured to be secured to a printed circuit board. Each terminal includes a spring contact. The cover can be moved relative to the base around the hinge to move the cover from an open orientation in which the cover is not within the cavity to a closed orientation in which the cover is positioned within a cavity in the base, and can be moved from the closed orientation to the open orientation A latch is provided to lock the cover to the base when the cover is in the closed orientation. Upon movement of the cover from the open orientation to the closed orientation, the spring contacts on the terminals engage contact pads on the printed circuit board. The terminals remain under compression providing intimate electrical contact with transverse wiping.

DETAILED DESCRIPTION

[0035] The detailed description that follows describes exemplary embodiments and the features disclosed are not intended to be limited to the expressly disclosed combination(s). Therefore, unless otherwise noted, features disclosed herein may be combined together to form additional combinations that were not otherwise shown for purposes of brevity.

[0036] In consumer markets power connectors are used to supply printed circuit boards in white goods with current to the appliance control circuit board. Currently, original equipment manufacturers have to use headers and connectors to allow mating to the middle of a printed circuit board. This method adds costs of headers, soldering and process cost, and process scrap cost. A solution to minimize these drawbacks is to provide a low-cost crimped harness connector that can terminate and mate to the middle of a printed circuit board without the use of a header.

[0037] A first embodiment of an electrical connector 20 that connects to a printed circuit board 22 without a header is shown in FIGS. 1-18 and a second embodiment of an electrical connector 20’ that connects to a printed circuit board 22 without a header is shown in FIGS. 6-8 and 19-33. The connector 20, 20 provides an electrical connection between a cable (not shown) and the printed circuit board 22.

[0038] Attention is invited to the first embodiment of the connector shown in FIGS. 1-18. The connector 20 includes a base 24 and a cover 26 which are attached to each other by a hinge 28, and a plurality of electrical terminals 30 mounted in the cover 26.

[0039] The base 24 is formed from an insulative material and has a first wall 32, a second wall 34 extending perpendicularly outwardly from the first wall 32 at a first end thereof, and a third wall 36 extending perpendicularly outwardly from the first wall 32 at a second end thereof such that an opening or cavity 38 is formed by the walls 32, 34, 36 The walls 32, 34, 36 generally form a“U” shape. The walls 32, 34, 36 define a mating end 40 of the base 24 which is configured to engage the printed circuit board 22 and a mounting end 42 which is opposite to the mating end 40.

[0040] As best shown in FIGS. 2 and 3, the first wall 32 has first and second cutouts 44, 46 and first and second recesses 48, 50 which are in communication with the cutouts 44, 46. Each cutout 44, 46 extends between inner and outer surfaces 32a, 32b of the first wall 32.

The inner surface 32a forms a surface of the cavity 38. The first cutout 44 extends a predetermined distance from the mating end 40 and extends a predetermined distance inwardly from the second wall 34. The second cutout 46 extends a predetermined distance from the mating end 40 and extends a predetermined distance inwardly from the third wall 36 As a result, the first wall 32 has a first wall portion 52 which is narrower than a second wall portion 54 and generally forms a“T” shape. Each recess 48, 50 extends a predetermined distance inwardly from the outer surface 32b of the first wall 32. As shown, the first recess 48 extends a predetermined distance from the mating end 40 and extends a predetermined distance from the first cutout 44 toward the second cutout 46, and the second recess 50 extends a predetermined distance from the mating end 40 and extends a predetermined distance from the second cutout 46 toward the first cutout 44. As a result, a first shoulder 56 is formed by the first cutout and recess 44, 48 and a second shoulder 58 is formed by the second cutout and recess 46, 50.

[0041] Each of the second and third walls 34, 36 have a planar inner surface 34a, 36a which face each other and forms a surface of the cavity 38, and an opposite outer surface 34b, 34b. As best shown in FIG. 5, each of the second and third wails 34, 36 has first and second cutouts 60, 62 that extend between the inner and outer surfaces 34a, 34b, 36a, 36b of the walls 34, 36 (the cutouts 60, 62 are only shown in wall 34). The first cutout 60 extends a predetermined distance from the mating end 40 and extends from the first wall 32, The first cutout 60 in the second wall 34 is in communication with the first cutout 44 in the first wall 32. The second cutout 62 extends a predetermined distance from the mating end 40 and extends a predetermined distance from an outer end 32c, 34c of each wall 34, 36. The first cutout 60 in the third wall 36 is in communication with the second cutout 46 in the first wall 32. As a result, each wall 34, 36 has a first wall portion 64 which is narrower than a second wall portion 66 and generally forms a“T” shape.

[0042] A plurality of spaced apart ribs 68 extend from the inner surface 32a of the first wall 32 and into the cavity 38. Each rib 68 has an elongated wall 70 wiiich extends along the first wall portion 52 and along a section of the second wall portion 54 and into the cavity 38, and a tab 72 which extends from an end of the wall 70 and into the cavity 38. The tab 72 extends further into the cavity 38 than the wall 70 such that each rib 68 generally forms an L- shape. In an embodiment, each wall 70 has an end at the mating end 40 and extends toward the mounting end 42. The second end of each rib 68 is spaced from the mounting end 42. In each rib 68, the wall 70 and the tab 72 may have the same width wiiich is defined between side surfaces of the wall 70 and tab 72.

[0043] In an embodiment, a series of deflectable board mounting lugs 74 extend from each second wall porti on 66 at the mati ng end 40 of the base 24 and through the cutouts 60, 62, The board mounting lugs 74 are configured to be inserted into apertures 76 formed in the printed circuit board 22 to secure the base 24 to the printed circuit board 22. In this embodiment, each board mounting lug 74 has a locking shoulder 78 which engages a surface of the printed circuit board 22 once the board mounting lugs 74 are passed through the apertures 76 A separate locating tab 80 may extend from the first wall portion 52 at the mating end 40 of the base 24 and is configured to be inserted into an aperture 82 formed in the printed circuit board 22. In another embodiment, the mating end 40 of the base 24 is surface mounted (not shown) to the printed circuit board 22.

[0044] The cover 26 is formed from an insulative material and includes a wall 84 having a mating end 86 which is configured to engage the printed circuit board 22 and a mounting end 88 which is opposite to the mating end 86, and side surfaces 84a, 84b, 84c, 84d which extend between the mating end 86 and the mounting end 88. A plurality of spaced apart cavities 90 are provided through the wall 84 and extend from the mating end 86 toward the mounting end 88. Each cavity 90 has a pair of recesses 92 extending outwardly therefrom in opposite directions toward the side surfaces 84b, 84d, respectively. The recesses 92 extend from the mating end 86 toward the mounting end 88 and along a portion of the cavity 90. Passageways 94 are in communication with the cavities 90 and each passageway 94 extends from the side surface 84c to the respective cavity 90. Each passageway 94 further extends from the mating end 86 toward the mounting end 88. The passageway 94 is offset from the respective cavity 90. Each passageway 94 has a width which is slightly greater than the width of the ribs 68.

10045 f A first retaining arm 96 extends from the side surface 84c proximate to the side surface 84b and extends a predetermined distance from the mating end 86 toward the mounting end 88. A second retaining arm 98 extends from the side surface 84b proximate to the side surface 84d and extends a predetermined distance from the mating end 86 toward the mounting end 88. A board lug retaining projection 100 extends outwardly from an outer side surface 94a, 96a of each retaining arm 96, 98.

[0046] A latch arm 102 extends from the side surface 84c and is proximate to, but spaced from the first retaining arm 96. A latch arm 104 extends from the side surface 84c and is proximate to, but spaced from the second retaining arm 98. Each latch arm 102, 104 has a barb 106 at its free end and the barbs 106 face each other.

[0047] The hinge 28 connects the base 24 to the cover 26 and allows the cover 26 to rotate relative to the base 24 around an axis defined by the hinge 28. In an embodiment, the hinge 28 is formed from a flexible insulative material and is integrally molded between the base 24 and the cover 26. The hinge 28 extends between the mounting ends 42, 88 of the base 24 and the cover 26.

[0048] The terminals 30 are formed from an electrically conductive material, such as copper or copper-based alloy. As best shown in FIGS. 6-8, each terminal 30 has a contacting section 108 which is configured to provide an electrical connection to the printed circuit board 22, a cable mounting section 110 which is configured to be coupled to the cable, and a retaining section 112 which connects the contacting section 108 to the cable mounting section 1 10

10049 f The contacting section 108 includes a resilient spring contact 114 formed in a loop back geometry and a contact dimple 118. As best shown in FIG. 8 in which the contacting section 108 is unflexed, the spring contact 114 includes a curved section 116a which extends from the retaining section 112, a straight section 116b which extends from an end of the curved section 116a and is perpendicular to a centerline of the terminal 30, a curved section 116c which extends from an end of the straight section 116b, a straight section 116d which extends from an end of the curved section 116c and is angled relative to the centerline of the terminal 30, a curved section 116e wiiich extends from an end of the straight section 116d and curves back toward the section 1 16b, a straight section 116f which extends from an end of the curved section 116e and is angled relative to the centerline of the terminal 30, and a curved section 116g which extends from an end of the straight section 1 16f and contacts the straight section 116b. An opening 120 is formed within the spring contact 114. The loop back geometry essentially creates a double cantilever type contact. The contact dimple 118 is formed on the curved section 116e which forms an outermost portion of the spring contact 114.

[0050] The cable mounting section 110 is configured to receive the cable. In an embodiment, the cable mounting section 110 is generally U-shaped and includes a curved base wall 122 and side walls 124, 126 extending from the base wall 122 along tangent lines of the base wall 122 such that a cavity 128 is formed therein. Each side wall 124, 126 has an end through which the cable is initially inserted and an opposite rear end which is proximate to the retaining section 112. A notch 130, 132 is provided in each side wall 124, 126 at the end of each side wall 124, 126. The notches 130, 132 align with each other.

[0051] The retaining section 112 extends between the contacting section 108 and the cable mounting section 1 10. The retaining section 112 has a base wall 134 having side walls 136, 138 extending perpendicularly from the base wall 134 such that a cavity 140 is formed therein. Each side wall 136, 138 has a cover engaging spring arm 140 extending outwardly from the cavity 140. The spring arms 140 may align with each other

[0052] The connector 20 is assembled together and secured to the printed circuit board 22 as shown in sequence with respect to FIGS. 9-16. [0053J FIG. 9 shows the insertion of the terminals 30 into the cavities 90 of the cover 26. Initially, the cover 26 is in an open orientation in which the cover 26 is not within the cavity 38 of the base 24 The terminals 30 are inserted through the mounting end 88.

[0054] FIG. 10 shows the terminals 30 positioned and secured within the cavities 90 of the cover 26. For each terminal 30, the contacting section 108 extends partially outwardly from the mating end 86 of the cover 26, the cable mounting section 1 10 is proximate to the mounting end 88 of the cover 26, and the cover engaging protrusions 142 seat within the recesses 92. Each terminal 30 is held securely in its cavity 90 by the cover engaging protrusions 142. The cables (not shown) may be attached to the terminals 30 prior to insertion of the terminals 30 into the cavities 90, or after insertion of the terminals 30 into the cavities 90. As shown in FIG. 2, the notch 132 in each terminal 30 is accessible through the respective passageway 94 when viewing the connector 20 from the side 84c

[0055] As shown in FIG. 11, the cover 26 is partially rotated from this open orientation around the axis of the hinge 28, and the cover 26 enters into the ca vity 38 of the base 24. The cables (not shown) are essentially vertically aligned for ease of positioning on the printed circuit board 22 When the cover 26 is rotated around the hinge 28, the board lug retaining projections 100 on the retaining arms 96, 98 slide along the planar inner surfaces 34a, 36a of the walls 34, 36.

[0056] The connector 20 is then mounted to the printed circuit board 22 such that the mating ends 40, 86 of the base 24 and the cover 26 are in proximity to the printed circuit board 22. FIG. 12 shows the insertion of the connector 20 into the apertures 76, 82 on the printed circuit board 22 (in the non-surface mounted embodiment). The connector 20 is further pressed to the printed circuit board 22 in FIG. 13 and the board mounting lugs 74 deflect as the board mounting lugs 74 enter into the apertures 76. After the locking shoulders 78 pass through the apertures 76 in the printed circuit board 22 and engage the back edge of the printed circuit board 22, the board mounting lugs 74 resume their undeflected condition to lock the connector 20 to the printed circuit board 22.

[0057] After the connector 20 is mounted to the printed circuit board 22, the cover 26 is further rotated around the hinge 28 as shown in FIGS. 13 and 14. As the cover 26 is further rotated, the cover 26 moves further into the cavity 38 of the base 24 and the board lug retaining projections 74 on the retaining arms 96, 98 continue to slide along the planar inner surfaces 34a, 36a of the walls 34, 36 The ribs 68 enter into the passageways 94 and slide within the passageways 94. In an embodiment, the ribs 68 fill the passageways 94. As the cover 26 is further rotated, the contact dimple 118 on each contacting section 108 engages and slides along a respective conductive contact pad 144 on the printed circuit board 22. The retaining arms 96, 98 and the latch arms 102, 104 enter into the cutouts 44, 46, and the barbs 106 seat within the recesses 48, 50 and engage the shoulders 56, 58 to hold the cover 26 securely into this final position thereby providing a first lock, and the tabs 72 seat within the notches 132 in the terminals 30 to provide a secondary lock (it is to be noted that notch 130 can be eliminated).

[0058] FIGS. 15 and 16 show the cover 26 fully rotated around the axis of the hinge 28 to a final mounted position in which the cover 26 is in a closed orientation. In this final mounted position, the mating ends 40, 86 of the base 24 and the cover 26 are proximate to, and engage against, the printed circuit board 22, and the mounting ends 42, 88 are aligned. In the final position, the contact dimple 118 on each contacting section 108 engages the respective conductive contact pad 144. As illustrated in FIGS. 14 and 16, the contacting section 108 of the terminal 30 is shown wiping the contact pad 144 and simultaneously being compressed such that the spring contacts 114 can be deflected to be substantially within the cavities 90 of the cover 26 when the cover 26 is in the closed orientation. This therefore builds up the normal contacting forces between the spring contacts 142 and the contact pads 144 to ensure electrical connection.

[0059] The geometry of the cutouts 44, 46, the recesses 48, 50 and the latch arms 102, 104, provide for a removal access provision on the hinge side of the connector 20 in which the latch arms 102, 104 can be deflected away from the shoulders 56, 58. A user’s fingers can engage and press the latch arms 102, 104 toward the respective retaining arms 96, 98 to remove the barbs 106 from the recesses 48, 50 and from engagement with the shoulders 56, 58 The cover 26 can thereafter be rotated in a reverse fashion around the hinge 28 from the closed orientation back to the open orientation.

[0060] As also shown in FIGS. 17 and 18, each board lug retaining projection 100 on the retaining arms 96, 98 act as a board mounting lug reinforcement feature. Upon complete rotation of the cover 26 to its closed orientation, the board lug retaining projections 100 are disposed adjacent the board mounting lugs 74. The board lug retaining projections 100 inhibit the reverse deflection of the board mounting lugs 74 so that the board mounting lugs 74 cannot be withdrawn from the apertures 76, essentially clamping the connector 20 to the printed circuit board 22.

[0061] While the cutouts 44, 46 and the recesses 48, 50 are shown and described as being on the base 24 and the latch arms 102, 104 are shown and described as being on the cover 26, the cutouts 44, 46 and the recesses 48, 50 may he provided on the cover 26 with the latch arms 102, 104 provided on the base 24.

[0062] Attention is invited to the second embodiment of the connector 20’ shown in FIGS. 6-8 and 19-33. The connector 20’ of the second embodiment is identically formed to that of the connector 20 of the fi rst embodiment, except for the differences noted herein which are denoted by reference numerals with a prime thereafter. The same reference numerals are used to denote identical elements and the specifics are not repeated herein.

[0063] The base 24’ of the connector 20’ is identically formed to the base 24, expect that the second and third walls 34’, 36’ are generally rectangular and do not have the first and second wall portions 64, 66 such that the first and second cutouts 60, 62 are not provided. Instead, the second and third wails 34 , 36’ extend from the mating end 40 of the base 24 to the mounting end 42 of the base. The board mounting lugs 74 extend from second and third walls 34, 36 at the mating end 40 of the base 24. The first cutout 44’ in the first wall 32 extends between inner and outer surfaces 32a, 32b of the first wall 32, extends a

predetermined distance from the mating end 40 and extends a predetermined distance inwardly fro the second wall 34. The first cutout 44’ in the first wall 32 extends between inner and outer surfaces 32a, 32b of the first wall 32, extends a predetermined distance from the mating end 40 and extends a predetermined distance inwardly from the third wall 36.

[0064] The cover 26’ of the connector 20’ is identically formed to the cover 26, expect that the retaining arms 96, 98 and the board lug retaining projections 100 have been replaced by latch arms 146, 148 which extend from the side surface 84c Latch arm 146 is proximate to, but spaced from the latch arm 102; latch arm 148 is proximate to, but spaced from the latch arm 104. Each latch arm 146, 148 has a barb 150 at its free end. The barb 150 on latch arm 146 faces away from the barb 106 on the latch arm 102; the barb 150 on latch arm 148 faces away from the barb 106 on latch arm 104

[0065] The connector 20’ is assembled together and secured to the printed circuit board 22 as showm in sequence with respect to FIGS 24-33.

[0066] FIG. 24 shows the insertion of the terminals 30 into the cavities 90 of the cover 26’. Initially, the cover 26’ is in an open orientation in which the cover 26’ is not within the cavity 38 of the base 24’ The terminals 30 are inserted through the mounting end 88.

[0067] FIG. 25 shows the terminals 30 positioned and secured within the cavities 90 of the cover 26’. For each terminal 30, the contacting section 108 extends partially outwardly from the mating end 86 of the cover 26’, the cable mounting section 110 is proximate to the mounting end 88 of the cover 26’, and the cover engaging protrusions 142 seat within the recesses 92 Each terminal 30 is held securely in its cavity 90 by the cover engaging protrusions 142. The cables (not shown) may be attached to the terminals 30 prior to insertion of the terminals 30 into the cavities 90, or after insertion of the terminals 30 into the cavities 90. The notch 132 in each terminal 30 is accessible through the respective passageway 94 when viewing the connector 20’ from the side 84c.

[0068] As shown in FIG. 26, the cover 26’ is partially rotated from this open orientation around the axis of the hinge 28, and the cover 26’ enters into the cavity 38 of the base 24’.

The cables (not shown) are essentially vertically aligned for ease of positioning on the printed circuit board 22. When the cover 26’ is rotated around the hinge 28, the barbs 150 on the latch arms 146, 148 slide along the planar inner surfaces 34a, 36a of the walls 34’, 36’.

[0069] The connector 20’ is then mounted to the printed circuit board 22 such that the mating ends 40, 86 of the base 24’ and the cover 26’ are in proximity to the printed circuit board 22. FIG. 27 shows the insertion of the connector 20’ into the apertures 76, 82 on the printed circuit board 22 (in the non-surface mounted embodiment). The connector 20’ is further pressed to the printed circuit board 22 in FIG. 28 and the board mounting lugs 74 deflect as the board mounting lugs 74 enter into the apertures 76. After the locking shoulders 78 pass through the apertures 76 in the printed circuit board 22 and engage the back edge of the printed circuit board 22, the board mounting lugs 74 resume their undeflected condition to lock the connector 20’ to the printed circuit board 22.

[0070] After the connector 20’ is mounted to the printed circuit board 22, the cover 26’ is further rotated around the hinge 28 as shown in FIGS. 28 and 29. As the cover 26’ is further rotated, the cover 26’ moves further into the cavity 38 of the base 24’ and the barbs 150 on the latch arms 146, 148 continue to slide along the planar inner surfaces 34a, 36a of the walls 34’, 36’. The ribs 68 enter into the passageways 94 and slide within the passageways 94. In an embodiment, the ribs 68 fill the passageways 94. As the cover 26’ is further rotated, the contact dimple 118 on each contacting section 108 engages and slides along the respective conductive contact pad 144 on the printed circuit board 22. The latch arms 102, 104, 146,

148 enter into the cutouts 44’, 46’, and the barbs 106 seat within the recesses 48, 50 and engage the shoulders 56, 58 and the barbs 150 engage the respective second and third walls 34, 36 to hold the cover 26’ securely into this final position thereby providing a first lock, and the tabs 72 seat within the notches 132 in the terminals 30 to provide a secondary lock (it is to be noted that notch 130 can be eliminated).

[0071] FIGS. 30 and 31 show the cover 26’ fully rotated around the axis of the hinge 28 to a final mounted position in which the cover 26’ is in a closed orientation. In this final mounted position, the mating ends 40, 86 of the base 24’ and the cover 26’ are proximate to, and engage against, the printed circuit board 22, and the mounting ends 42, 88 are aligned. In the final position, the contact dimple 1 18 on each contacting section 108 engages the respective conductive contact pad 144. As illustrated in FIGS. 29 and 31, the contacting secti on 108 of the terminal 30 is shown wiping the contact pad 144 and simultaneously being compressed such that the spring contacts 114 can be deflected to be substantially within the cavities 90 of the cover 26’ when the cover 26’ is in the closed orientati on. This therefore builds up the normal contacting forces between the spring contacts 142 and the contact pads 144 to ensure electrical connection.

[0072] The geometry' of the cutouts 44’, 46’, the recesses 48, 50 and the latch arms 102, 104, 146, 148 provide for a removal access provision on the hinge side of the connector 20’ in which the latch arms 102, 104 can be deflected away from the shoulders 56, 58 and the latch arms 146, 148 can be deflected away from the second and third walls 34, 36. A user’s fingers may be able to engage and press the latch arms 102, 104 toward the respective latch arms 146, 148 to remove the barbs 106 from the recesses 48, 50 and from engagement with the shoulders 56, 58, and a user’s fingers may be able to engage and press the latch arms 146, 148 toward the respective latch arms 102, 104 to remove the barbs 150 from engagement with the second and third walls 34, 36. Alternatively, an appropriate tool (not shown) may be utilized to perform these functions. The cover 26’ can thereafter be rotated in a reverse fashion around the hinge 28 from the dosed orientation back to the open orientation.

[0073] While the cutouts 44’, 46’ and the recesses 48, 50 are shown and described as being on the base 24’ and the latch arms 102, 104, 146, 148 are shown and described as being on the cover 26’, the cutouts 44’, 46’ and the recesses 48, 50 may be provided on the cover 26’ with the latch anus 102, 104, 146, 148 provided on the base 24’.
