Abstract

A 110-style patch cord includes: a plug having opposed front and rear ends and a generally horizontal support surface; a plurality of electrical contacts mounted in the plug, each contact including a generally vertically oriented blade, the blades having exposed front edges positioned above the support surface and defining a first vertical plane; and a cable with a plurality of conductors, wherein each contact is electrically connected to a respective one of the conductors, the cable extending from the front end of the plug. At least one anti-snagging gusset is mounted on the support surface in front of the first plane.

Claims

1. A 110-style patch cord, comprising:

a plug having opposed front and rear ends and a generally horizontal support surface;

a plurality of electrical contacts mounted in the plug, each contact including a generally vertically oriented blade, the blades having at least partially exposed front edges positioned above the support surface and defining a generally vertical first plane; and

a cable with a plurality of conductors, wherein each contact is electrically connected to a respective one of the conductors, the cable extending from the front end of the plug;

wherein at least one anti-snagging gusset is mounted on the support surface in front of the first plane.

2. The patch cord defined in claim 1, wherein at least some of the blades are arranged in a generally horizontal row, and wherein the at least one gusset slopes upwardly to meet a lower edge of one of the blades in the generally horizontal row.

3. The patch cord defined in claim 1, wherein the at least one gusset is a plurality of gussets.

4. The patch cord defined in claim 3, wherein each of the plurality of gussets is substantially coplanar with a corresponding blade.

5. The patch cord defined in claim 3, wherein the plug has a ceiling, and wherein the ceiling does not extend forwardly beyond the first plane.

6. The patch cord defined in claim 5, further comprising discontinuous partitions that extend from the ceiling to the support surface, the blades being located in contact slots in the partitions.

7. The patch cord defined in claim 6, wherein each of the gussets merges with a respective partition.

8. The patch cord defined in claim 1, wherein the plug comprises a base and a separate cover.

9. The patch cord defined in claim 8, wherein the contacts and the at least one gusset are located on the base.

10. The patch cord defined in claim 8, wherein the cover includes generally horizontal grooves that receive contacts and generally vertical grooves intersecting with the horizontal grooves that receive individual conductors.

11. The patch cord defined in claim 8, wherein the cover includes a ceiling with a downwardly depending latch, the latch configured to be received by a patch panel, and wherein the ceiling is attached to the cover via a living hinge.

12. The patch cord defined in claim 8, wherein the cover includes a pair of generally forwardly-extending cord grip arms that grip the cord.

13. The patch cord defined in claim 10, wherein the cover includes a shelf with a plurality of apertures, each of the apertures positioned to receive and feed a pair of conductors to respective ones of the generally vertical slots.

14. The patch cord defined in claim 1, wherein each of the electrical contacts has an insulation displacement contact (IDC) on an end opposite the blade.

15. The patch cord defined in claim 1, wherein the front end of the plug is rounded.

16. A method of terminating a patch cord having a plurality of electrical conductors, the conductors being arranged in differential pairs, the method comprising the steps of:

providing a base in which are mounted electrical contacts, each of the electrical contacts including a blade at one end and an insulation displacement contact (IDC) at the other end, the blades being generally vertically oriented, arranged in one or more generally horizontal rows, and extending in a forward direction;

providing a cover comprising a plurality of generally vertically oriented grooves, each of the grooves sized to receive a conductor;

inserting a cable comprising the plurality of conductors into an aperture located on a forward end of the base;

inserting each of the conductors of the cable into a respective one of the grooves in the cover; and

interconnecting the base and the cover such that the IDCs in the base form electrical contact with the conductors inserted in the grooves in the cover.

17. The method defined in claim 16, wherein the cover includes generally horizontal slots that intersect with respective generally vertical slots, the generally horizontal slots receiving the IDCs during the interconnecting step.

18. The method defined in claim 17, further comprising the step of threading pairs of conductors through apertures in a shelf on the cover prior to inserting the conductors into a respective groove.

19. The method defined in claim 16, wherein the interconnecting step includes latching the cover to the base via a latch located on the base.

20. The method defined in claim 16, wherein the cover includes a ceiling attached thereto via a living hinge.

21. The method defined in claim 16, wherein the cover includes forwardly-extending grip arms, and wherein the interconnecting step includes flexing the gripping arms with the base to clamp the arms onto the cable.
