6. The jack assembly in accordance with claim 1 wherein the IDC is positioned within an IDC channel formed by the adjacent arms, the IDC channel and the conductor channel intersecting each other at a non-orthogonal angle.
7. The jack assembly in accordance with claim 1 wherein each IDC has an operative width and each gap has a gap width, wherein the gap width is at least twice the operative width of the IDC.
8. The jack assembly in accordance with claim 2 further comprising a plurality of contacts extending from the front end to the rear end of the jack housing, the jack housing comprising the non-conductive material having conductive particles dispersed therein, wherein the cavity is configured to avoid formation of a conductive path between the jack housing and the contacts.
9. An electrical connector cap configured to push a plurality of conductors into corresponding insulation displacement contacts (IDCs) when the connector cap is mounted to a jack housing, each IDC extending across a conductor channel such that when a conductor is inserted into the IDC the conductor rests within the conductor channel, the connector cap comprising:
a body being formed from a non-conductive material having conductive particles dispersed therein, the body having an inner surface; and
a plurality of crosswalls projecting outwardly from the inner surface, each crosswall having first and second wall portions separated by a gap, each crosswall positioned to be inserted into a corresponding conductor channel such that the IDC fits within the gap when the first and second wall portions push the corresponding conductor into the conductor channel.
10. The connector cap in accordance with claim 9 wherein each IDC has an operative width and each gap has a gap width, wherein the gap width is at least twice the operative width of the IDC.
11. The connector cap in accordance with claim 9 further comprising only one pair of opposing sidewalls projecting outward from the inner surface and perpendicular to the inner surface.
12. The connector cap in accordance with claim 9 further comprising a paint for color-coding the connector cap.
13. The connector cap in accordance with claim 9 wherein the inner surface includes a nozzle opening for receiving a cable having a plurality conductors.
14. The connector cap in accordance with claim 9 wherein the non-conductive material comprises a thermoplastic polymer and the conductive particles comprise stainless steel fibers.
15. The connector cap in accordance with claim 9 wherein the connector cap does not include a conductive coating and/or conductive shield for reducing EMI.
16. A jack assembly for interconnecting cables, the jack assembly comprising:
a jack housing having a cavity configured to engage a plug from a first cable;
a conductor channel formed at an end of the jack housing, the conductor channel configured to receive a conductor from a second cable;
an insulation displacement contact (IDC) held within the conductor channel, the IDC extending across the conductor channel such that the conductor rests within the conductor channel when the conductor is inserted into the IDC; and
a connector cap configured to be mounted to the end of the jack housing to cover the conductor channel, the cap being formed from a non-conductive material having conductive particles dispersed therein, the cap comprising a crosswall that is sized and shaped to be inserted into the conductor channel when the cap is mounted to the jack housing, the crosswall having first and second wall portions separated by a gap, the IDC fitting within the gap when the crosswall is inserted into the conductor channel.
