DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the several views of the drawings, the radial termination system for a communication connector of the present invention is shown and is generally indicated as 10.
Referring initially to FIGS. 1-3, a first embodiment of the radial termination system 10 generally includes a stuffer cap component 12 and a communication connector 14. While the communication connector 14 illustrated throughout the drawings is a jack connector component, the radial termination system 10 of the present invention is equally applicable to a plug connector component.
Referring particularly to FIG. 4, the stuffer cap component 12 includes a front end and a rear end having an opening sized and configured for selective passage therethrough of a plurality of conductor pairs, including individual wires 16, of the cabling. A plurality of slots 18 are concentrically arranged on the front end of the stuffer cap component 12 are sized for selective pressed receipt of each wire 16 of each of the plurality of conductor pairs. More specifically, a user may prepare the cable for termination by stripping the cable jacket at a certain length to expose the twisted pairs of wires 16 and subsequently press the individual wires 16 down into the slot 18. The wires 16 are then trimmed flush with the edge of each corresponding slot 18.
Referring particularly to FIG. 5, the communication connector 14 includes a receptacle component 20 having a back end configured for mating with the front end of the stuffer cap component 12. A plurality of insulation displacement contacts (IDCs) 22 on the inner facing surface of the receptacle component 20 are positioned adjacent and concentrically perpendicular to the back end of the receptacle component 20. Each of the plurality of IDCs 22 are aligned for engaged abutment with a corresponding one of the wires 16 of the plurality of conductor pairs when the stuffer cap component 12 and communication connector 14 are in the locked position (see FIGS. 9 and 10).
The stuffer cap component 12 includes at least one keying member 24 having a unique keying member geometry. In one embodiment, stuffer cap components 12 include a plurality of unique keying geometries. For example, the stuffer cap component 12 illustrated in FIGS. 1-10 includes two keying members 24, each having different keying geometries. The receptacle component 20 includes at least one keying element 26 which is geometrically sized and configured for aligned passage therethrough of a corresponding one of the at least one keying members 24.
Referring to FIGS. 6-10, the radial termination process is illustrated. Referring specifically to FIGS. 6 and 7, the stuffer cap component 12 is shown with an orientation slightly to the left in the counter-clockwise direction (approximately 22.5 degrees), allowing the two keying members 24 to be in alignment with the two corresponding keying elements 26. The associated cabling of the wires 16 is not shown throughout the illustrations for the purposes of clarity. Referring specifically to FIG. 6, wherein only a portion of the wires 16 are shown (the stuffer cap component is otherwise not illustrated for the purposes of clarity), each wire 16 is shown adjacent to the corresponding IDC 22. The PCB 28, in connection with IDCs 22, can be viewed in part through the openings formed by the keying elements 26. Referring specifically to FIG. 7, the two keying members 24 are shown in alignment with the two corresponding keying elements 26.
Referring to FIGS. 8-10, after the two keying members 24 have passed through the two corresponding keying elements 26, the stuffer cap component 12 is axially rotated by a user in the clockwise direction relative to the receptacle component 20 until the wires 16 are terminated into the respective IDCs 22 (see FIGS. 9 and 10). The keying features further serve as a locking mechanism for maintaining the stuffer cap component 12 and communication connector 14 in the locked position. As shown throughout the drawings, the body of each of the IDCs 22 may be concentrically curved such that the concave surface of each IDC 22 is inwardly facing to facilitate radial termination.
Referring to FIGS. 11-14, another embodiment of the stuffer cap 12 is shown, wherein the wires 16 in slots 18 are terminated in a generally perpendicular orientation to the PCB 28. As shown in FIGS. 12A and 12B, the distal ends of the IDCs 22 are angled inwards toward the center of the communication connector 14 at approximately a 45-degree angle. Moreover, the IDCs 22 include a curvature of the split within the contact to enable the wires 16 to travel radially as termination occurs.
Specifically referring to FIGS. 13 and 14, a stuffer key protrusion 30 is sized for fitted passage through an IDC surround slot 32 formed on the IDC surround housing 34 of the communication connector 14. As shown, the IDC surround slot 32 is L-shaped, such that two movements are required as part of the keying mechanism for this particular embodiment-(1) the stuffer cap component 12 is pressed toward the IDC surround housing 34 along the path of the first portion 32A of the IDC surround slot 32 and (2) the stuffer cap component 12 is rotated along the path of the second portion 32B of the IDC surround slot 32 to terminate the wires 16 and lock the stuffer cap component 12 with the communication connector 14.
While the orientation of the stuffer caps 12, IDCs 22, and keying features thus far presented have been shown and described as necessitating clockwise rotation for termination, it should be understood that counterclockwise rotation is equally practical from a structural standpoint.
Generally, two styles of communication connectors 14 may be provided-(1) an unshielded connector using standard polycarbonate type materials and lacking an internal shield connection and (2) a shielded connector utilizing conductive plastics or metallic die cast parts. The latter instance of the connector would include a shield connection to complete the continuity between a shielded plug and the shield of the cable. If the cable is shielded, the drain wire may be pushed through the far end of the stuffer cap component 12 to also be laced into a wire slot designed specifically for that purpose. If the shielded cable has an overall braid, the braid is pushed back over the cable jacket before the wires 16 are inserted into the stuffer cap component 12. The braid is later prepared by twisting and terminated to the clips provided for this purpose.
A combination of conductive plastic and cast metallic parts with an internal conductive bridge provide for both shielded and unshielded embodiments by substitution of standard plastic materials and population or no population of the conductive bridge between the front and back of the connector.
While the present invention has been shown and described in accordance with several preferred and practical embodiments, it is recognized that departures from the instant disclosure are contemplated within the spirit and scope of the present invention.
