Description:
PLATE FOR CABLE CONNECTOR ATTACHMENTS

BACKGROUND OF THE INVENTION

1. Field of the Invention

[001] The present invention relates to a mount system for facilitating ordered mating of plural connectors. More particularly, the present invention relates to a mounting system used to connect jumper cables to trunk cables in an antenna tower environment. 2. Description of the Related Art

[002] A box unit for connecting jumper cables to trunk cables is known in the prior art of antenna tower wiring systems.

SUMMARY OF THE INVENTION

[003] The Applicant has appreciated a need for a connection structure and mounting system, which is simpler in design and less costly to manufacture. The Applicant has also appreciated a need for a design with an inexpensive keying system to simplify the assembly procedures in the field, making the connection process rather foolproof, such that jumper and trunk cables may only be connected in the proper manner.

[004] One type of connector, which may benefit from the present invention, is the type of mated connectors which exist between the jumper cables (extending up the antenna structure to the remote radio units) and the trunk cables extending down the tower to ground level equipment of the service provider. These connectors may be hybrid connectors (having both fiber and electrical elements). Alternatively, each connector may present only fiber connections or only electrical connections. Specific functions, like an alarm function, may be dedicated to its own keyed or non-keyed connector. Connector structures to achieve these and other objects are taught in the present disclosure.

[005] In accordance with the present invention, a mounting system for facilitating ordered mating of plural connectors includes a bracket having at least one feature for securing to a pole or wall. A plate is connected to the bracket and includes plural mounting positions.

[006] Optional grounding and/or surge arrestors may be included.

[007] In a keying embodiment, each mounting position has an inner perimeter shape different than the inner perimeter shapes of the other mounting positions. Each connector of plural first connectors includes a threaded portion holding a first nut with an outer perimeter having a shape being unique, as compared to the first nuts of other first connectors. The outer perimeter of the first nut seats into one, and only one, of the plural mounting positions of the plate.

[008] Optionally, a second plate may be mounted to, and spaced from, the first plate. The second plate includes plural keyholes which are aligned to the plural mounting positions. Each keyhole has an inner perimeter shape matching the inner perimeter shape of the mounting position to which the keyhole is aligned. The keyholes only permit a second connector, with a matching key nut, to pass therethrough and mate into the first connector in the aligned mounting position.

[009] Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications will become apparent to those skilled in the art from this detailed description.

[030] Figures 1 and 2 show a first embodiment of a mounting system 11 for facilitating ordered mating of plural connectors. The mounting system 11 includes a bracket first portion 13 having at least one feature for securing the bracket first portion 13 to a pole or wall and a bracket second portion 15 having at least one feature for securing the bracket second portion 15 to a pole or wall.

[031] A plate 17 is located between the bracket first portion 13 and said bracket second portion 15, e.g., directly connected to, or formed integrally with, the bracket first portion 13 and the bracket second portion 15. The plate 17 has plural mounting positions 19-1, 19-2, 19-3 and 19-4 for securing plural first connectors 21-1, 21-2, 21-3 and 21-4 (See Figure 2) thereto. Although four mounting positions 19 are shown in Figures 1 and 2, more or fewer mounting positions 19 may be included in the plate 17 to accommodate more or fewer first connectors 21.

[032] In one embodiment, the at least one feature for securing the bracket first portion 13 to a pole or wall includes two through holes or channels 23 A and 23B formed in the bracket first portion 13. Likewise, the at least one feature for securing the bracket second portion 15 to the pole or wall includes two through holes or channels 25 A and 25B formed in the bracket second portion 15. In Figures 1 and 2, a first hose clamp 27A is passed through the through holes or channels 23A/B of the bracket first portion 13, and a second hose clamp 27B is passed through the through holes or channels 25A/B of the bracket second portion 15. However, would be possible to use other fixing structures, such as a plate and threaded rods, or a C-clamp with two treaded ends passing through said through holes or channels 23A/B and 25A/B, and nuts attached to said threaded ends (as will be further explained in conjunction with the embodiment depicted in Figures 5 and 6).

[033] The plate 17 includes a plurality of tabs 29-1, 29-2, 29-3 and 29-4 cut therein. Each tab 29 is connected to remaining portions of the plate 17 by only one side 31 of the tab 29. The other remaining sides of the tab 29 are disconnected from the plate 17. Each tab 29 is bent at the one side 31 attached the plate 17, so as to extend at an angle relative to the remaining portions of the plate 17. The angle of extension is between ten to eighty degrees, such as approximately twenty five to fifty five degrees, and more preferably at an angle of approximately forty five degrees, as depicted in Figures 1-2. The angle of the tab 29 assists in routing water away from connectors in the mounting positions 19.

[034] Figure 2 is a perspective view of the mounting system 11 of Figure 1 with first connectors 21 fixed in the mounting positions 19 and a plurality of second connectors 33-1, 33-2, 33-3 and 33-4 mated to the plurality of first connectors 21-1, 21-2, 21-3 and 21-4, respectively. In a typical arrangement, the plurality of first connectors 21- 1, 21-2, 21-3 and 21-4 are attached to first cords 35-1, 35-2, 35-3 and 35-4, respectively, which each extend to equipment mounted proximate a top of a tower structure, such as remote radio units (RRUs). The plurality of second connectors 33-1, 33-2, 33-3 and 33-4 are attached to second cords 37-1, 37-2, 37-3 and 37-4, respectively, which extend to a transition 39. Within the transition 39, the optical fiber and/or electrical conductors within the second cords 33-1, 33-2, 33-3 and 33-4 are transitioned into ajacket of a larger trunk cable 40. The trunk cable 40 is routed to service provider equipment located proximate a bottom of the tower structure.

[035] Figure 3 is a perspective view of a modified mounting system 41 in accordance with the first embodiment. The modified mounting system 41 is the same as the mounting system of Figures 1 and 2, except for the inclusion of a grounding region 43 located on a modified plate 17'. The modified plate 17' differs from the plate 17 of Figures 1 and 2 by including additional surface area proximate the bracket second portion 15. The identically formed structures have been labeled with the same reference numerals and will not be described in detail again.

[036] The grounding region 43 includes plural through holes 45 for accepting ground wires 47. If additional grounding locations are needed, the grounding region 43 may optionally include a bus bar 49 mounted thereto by standoffs 50, wherein the bus bar 49 also includes plural through holes 45 for accepting ground wires 47.

[037] Figures 4 and 5 show a second embodiment of a mounting system 51 for facilitating ordered mating of plural connectors. The mounting system 51 includes a bracket first portion 53 having at least one feature for securing the bracket first portion 53 to a pole or wall.

[038] A plate 57 is attached to the bracket first portion 53, e.g., directly connected to, or formed integrally with, the bracket first portion 53. The plate 57 has plural mounting positions 59-1, 59-2, 59-3 and 59-4 for securing plural first connectors 81-1, 81-2, 81-3 and 81-4. The first connectors 82 will be described in greater detail with reference to Figure 7 hereinafter. Although four mounting positions 59 are shown in Figures 4 and 5, more or fewer mounting positions 59 may be included in the plate 57 to accommodate more or fewer first connectors 81.

[039] In one embodiment, the at least one feature for securing the bracket first portion 53 to a pole or wall includes two through holes or channels 63A and 63B formed in an upper area of the bracket first portion 53 and at least two through holes or channels 65A and 65B formed in a lower area of the bracket first portion 53. In Figures 4 and 5, first and second C-clamps 67 and 69 have treaded ends 71. The threaded ends 71 are passed through the through holes or channels 63A/B and 65A/B, and nuts 73 are attached to the threaded ends 71. In one embodiment (illustrated in Figure 5), two nuts 73 are threaded onto each threaded end 71, and the bracket first portion 53 is sandwiched between inner and outer nuts 73 on each threaded end 71.

[040] As best seen in Figure 5, the plate 57 extends at an angle to the bracket first portion 53, wherein the angle is not zero, ninety or one hundred eighty degrees. The angle may reside between ten to eighty degrees, such as approximately twenty five to fifty five degrees, and more preferably at an angle of approximately forty five degrees, as depicted in Figure 5. [041] The bracket first portion 53 also optionally includes one or more grounding regions, characterized by through holes 75 for accepting ground wires, like ground wires 47 in Figure 3. If additional grounding locations are needed, the grounding region(s) may optionally include a bus bar, like bus bar 49 of Figure 3, mounted thereto by standoffs, to provide additional through holes 75 for accepting ground wires 47.

[042] Figure 6 is a perspective view of a modified mounting system 80 in accordance with the second embodiment. The modified mounting system 80 is the same as the mounting system 51 of Figures 4 and 5 except for three modifications.

[043] First, Figure 6 demonstrates the inclusion of an optional surge arrestor 77 attached to a backside of the plate 57'. The surge arrestor 77 communicates with one or more connectors located within the plural mounting positions 59-1, 59-2, 59-3 and 59-4 of the plate 57'. The embodiment of Figures 1-3, as well as the other embodiments herein, may also include a surge arrestor 77, and one or more grounding regions 43. See the surge arrestor 77 in Figure 3, and the surge arrestor 77 and grounding region 43 in Figure 11.

[044] Second, Figure 6 demonstrates that the plural mounting positions 59-1, 59- 2, 59-3 and 59-4 may be sized differently to accept larger or smaller connectors. Examples of differently sized connectors include a small, dedicated, fiber optic connector, e.g. a single SC adapter for an alarm wire, a small, dedicated, electrical connector, e.g., a single pin socket for an alarm wire, a midsized, fiber optic connector, e.g., a duplex LC adapter for communication signaling, a midsized electrical connector, e.g., an RJ-type jack for communication signally, a larger hybrid connector, e.g., a connector having two LC duplex adapters for communications and three electrical pin sockets for power.

[045] Third, Figure 6 demonstrates that both the bracket first portion 53 and the plate 57' may include through holes 75 for accepting ground wires 47. Of course, the plate 57' may include through holes 75 on the opposite side of the surge arrestor 77, and a grounding bar 49 mounted on standoffs 50, if desired.

[046] Returning now to Figures 4-5, a keying aspect of the present invention will be described. Each of the plural mounting positions 59-1, 59-2, 59-3 and 59-4 has an inner perimeter shape formed in the plate 57, which is different than the inner perimeter shapes of the other mounting positions 59 in the plate 57. The inner perimeter shapes act as keying features to allow only one of a plurality of first connectors 81 to be attached into a particular mounting position 59 in the plate 57.

[047] Figure 7 is a perspective view of a first connector 81-2 of the plurality of first connectors 81 , in accordance with the present invention. The first connector 81-2 includes a first threaded portion 83 A holding a first nut 85-2 with an outer perimeter having a shape being unique, as compared to the first nuts 85 of other first connectors 81.

In the case of the first nut 85-2 shown in Figure 7, the outer perimeter shape is hexagonal.

Of course, many other shapes are possible, such as shapes including a pentagon (like mounting position 59-4), a square (like mounting position 59-3), a circle, a triangle, a circle with at least one flat edge portion, and a circle with evenly or unevenly spaced star tips (like the five star tips illustrated in mounting position 59-1).

[048] The first connector 81-2 includes a stop flange 89. The first threaded portion 83A is adjacent to the stop flange 89, and the first nut 85-2 is threaded onto the first threaded portion 83A until it abuts the stop flange 89. Then, the first nut 85-2 may be adhered to the stop flange 89 and/or the first threaded portion 83A by an adhesive, e.g., an epoxy.

[049] A second threaded portion 83B may be adjacent and optionally continuous to the first threaded portion 83 A. The first connector 81-2 is mounted to the plate 57 by first locating or seating the first nut 85-2 within the corresponding mounting position 59- 2 (having the matching hexagonal inner perimeter shape in the case of mounting position 59-2). Next, a portion of the plate 57 surrounding the matching inner perimeter shape of the mounting position 59-2 is sandwiched between the stop flange 89 and a second nut 82 threaded onto the second threaded portion 83B. See Figures 12-13 for an illustration of the second nut 82. An optional washer may be interposed between the second nut 82 and the plate 57, if desired.

[050] The embodiment of Figures 4-6 shows a keying arrangement, wherein first connectors 81 are allowed to mount only at designated mounting positions 59 in the plate 57. In other words, the first nut 85 must have a matching shape to the inner perimeter of the mounting position 59 before the first connector 81 will seat into the mounting position 59. By this arrangement, the first connectors 81 may be organized on the plate 57 by a pre-ordered scheme, and the plate 57 may be permanently labeled, e.g., by impressions formed into the plate 57, to indicate the communication channels, power channels or alarm functions to be located at the various mounting positions 59. For example, the first mounting position 59-1 may indicate a first RRU servicing a north facing antenna, the second mounting position 59-2 may indicate a second RRU servicing an east facing antenna, etc. The mounting positions 29-1, 29-2, 29-3 and 29-4 in the first embodiment depicted in Figures 1-3 could also include the above-described keying arrangements.

[051] In use, second connectors 33 from breakout cordage 37 of the trunk cable 40 are mated into the first connectors 81 in accordance with the function or service indicated by the placement of the first connectors 81 on the plate 57. Following the above example, if a second connector 33-2 is terminated on breakout cordage 37-2 from the truck cable 40, which communicates signals for the second RRU, a technician will mate that second connector 33-2 to the first connector 81-2 seated in the second mounting position 59-2 in the plate 57.

[052] In the embodiment of Figures 4-6, keying is only taking place with regard to the first connectors 81. The skill of the technician is being relied upon to determine which second connector 33 should be mated to which first connector 81. Hence, misconnections may occur. In the third embodiment of the present invention, both the first connector 81 and a second connector 91 have keying aspects to address this potential misconnection issue.

[053] Figures 9 and 10 show a rear and front perspective view, respectively, of a second connector 91-4 of a plurality of second connectors 91 , in accordance with the present invention. Each second connector 91 includes a third threaded portion 93 which extends up to a stop flange 94. The third threaded portion 93 holds a third nut 95. The third nut 95 may be adhered to the third threaded portions 93 and/or the stop flange 94 by an epoxy.

[054] The third nut 95 has an outer perimeter having a shape which is unique, as compared to the third nuts 95 of other second connectors 91. In the case of third nut 95-4 in Figures 8-10, the outer perimeter shape forms a pentagon, as best seen in Figure 8. Of course, many other shapes are possible, such as shapes including a hexagon (like mounting position 59-2), a square (like mounting position 59-3), a circle, a triangle, a circle with at least one flat edge portion, and a circle with evenly or unevenly spaced star tips (like the five star tips illustrated in mounting position 59-1).

[055] Each second connector 91 is structured to mate with a first connector 81 of said plurality of first connectors 81. In the case of the hybrid connectors shown in Figures 7 and 9-10, the connector faces include two LC duplex connectors/adapters and two conductive pins/sockets.

[056] Figures 11-13 show a third embodiment of a mounting system 101 for facilitating ordered mating of plural connectors. The mounting system 101 includes a bracket first portion 13 having at least one feature 23 A and 23B for securing the bracket first portion 13 to a pole or wall, and a bracket second portion 15 having at least one feature 25 A and 25B for securing the bracket second portion 15 to a pole or wall.

[057] A first plate 107 is located between the bracket first portion 13 and the bracket second portion 15, e.g., directly connected to, or formed integrally with, the bracket first portion 13 and the bracket second portion 15. The first plate 107 has plural mounting positions 109-1, 109-2, 109-3 and 109-4 for securing plural first connectors 81- 1, 81-2, 81-3 and 81-4. The first connectors 81 are the same as described above in connection with Figure 7. Although four mounting positions 109 are shown in Figure 11, more or fewer mounting positions 109 may be included in the first plate 107 to accommodate more or fewer first connectors 81.

[058] A second plate 111 is attached to and spaced from the first plate 107. The one embodiment, the second plate 111 is integrally formed with the first plate 107 and a bent section 113 formed at ninety degrees relative to the first plate 107, and at ninety degrees relative to the second plate 111 , creates the spacing. The second plate 111 has plural keyholes 115-1, 115-2, 115-3 and 115-4, which are aligned to the plural mounting positions 109-1, 109-2, 109-3 and 109-4, formed in the first plate 107. Each of the plurality of keyholes 115 has an inner perimeter shape formed in the second plate 111, which is different than the inner perimeter shapes of the other keyholes 115 formed in the second plate 111.

[059] In a preferred embodiment, the inner perimeter shape of each keyhole 115 matches the inner perimeter shape of the mounting position 109 in the first plate 107 to which the keyhole 115 is aligned, but is slightly larger in size than the inner perimeter shape of the aligned mounting position 109. The third nut 95 is slightly larger than the first nut 85, so that the third nut 95 extends outwardly of the stop flange 94, as best seen in Figure 10. Hence, by making the keyhole 115 slightly larger (as compared to the mounting hole 109), the third nut 95 passes through the keyhole 115 and the stop flange 94 does not contact any portion of the second plate 111, such that the entire second connector 91 passes through the keyhole 115, as best seen in Figure 13. Once, the second connector 91 passes through the keyhole 115, it may be mated to the first connector 81 in the aligned mounting position 109.

[060] In the third embodiment of Figures 11-13, keying is taking place with regard to the first connectors 81 and the second connectors 91. The skill of the technician is not being relied upon to determine which second connector 91 should be mated to which first connector 81. Hence, the likelihood of misconnections is greatly reduced.

[061] Only second connectors 91 with a third nut 95 with a shape matching a first nut 85 will be able to pass through the keyhole 115 to mate with a first connector 81 in the aligned mounting position 109. A second connector 91 with a third nut 95 not matching the shape of the first nut 85 on the first connector 81 in the aligned mounting position 109, will be blocked by the perimeter of the keyhole 115, so that a misconnection cannot occur. By this arrangement, the outer perimeter shape of the third nut 95 only permits the second connector 91 to be able to pass through one and only one of the plural keyholes 115.

[062] Figure 14 is a perspective view of modified mounting system 121 in accordance with the third embodiment. The modified mounting system 121 is the same as the mounting system of Figures 11-13 except that the second plate 111 is mounted to the pole or wall using the bracket first and second portions 13 and 15. Further, the second plate 111 is attached to the first plate 107 by threaded fasteners 123 and nuts 125, such that the spacing between the second plate 111 and the first plate 107 may be adjusted by sliding the threaded fasteners 123 within slot 127 and then tightening the nuts 125.
