A strain relief housing for use in a communication plug terminating a cable carrying a plurality of conductors. The housing includes a plurality of prongs for segregating the conductors from a cable that is received through a passage in the housing. Means for anchoring the cable in the passage serve to effectively eliminate stress on the electrical connections with the conductors inside the plug. In a preferred embodiment, the strain relief housing segregates the conductors in a substantially circular array, largely conforming to the arrangement of the conductors in a round cable.

Strain relief apparatus for use in a communication plug

A push nut fastener has first and second gripping openings. The first gripping opening is substantially circular and the second gripping opening is substantially rectangular. The substantially circular gripping opening has a plurality of blades or finger-like engagement portions extending from the outer circumference of the substantially circular gripping opening towards the center of the substantially circular gripping opening. The substantially rectangular gripping opening has a plurality of blades or finger-like engagement portions extending from the outer perimeter of the substantially rectangular gripping opening towards the center of the substantially rectangular gripping opening. The substantially rectangular gripping opening includes at least two blades or finger-like engagement portions, a respective blade extending from each of two opposing sides of the substantially rectangular gripping opening. The push nut may have flanges formed at two opposing ends of the member. The flanges may be formed integrally from the same piece of material as the push nut fastener. The flanges may have unequal lengths, to differentiate one end of the push nut fastener from the other end. The push nut fastener may be included in electrical components, for example in a DSX jack. An exemplary digital signal cross-connect jack has a respective pair of posts extending from each side, with a respective push nut fastened to each respective pair of posts.

A jack assembly is provided in which the central body of the assembly includes integrally cast posts for aligning and securing follower springs, wiper springs and spacers. To assemble the jack, the follower springs, wiper springs and spacers are stacked onto the posts and then secured with a pushnut that engages the posts with a friction fit, avoiding separation from the central body.

Jacks formed by die casting

A machine (46) for attaching an Insulation Displacement Connector (IDC) (10) to a cable (20) includes a fixture (76, 240) for engaging and arranging individual wires (18-18) in the cable in parallel, spaced-apart relationship. The machine also includes a press mechanism (51, 54, 101, 102)) for engaging a mandrel (12) of the IDC (10) and for pressing it against the wires (18-18) engaged by the fixture (76, 240) to seat each wire in a corresponding mandrel channel (14). The press mechanism (51, 54, 101 and 102) further functions to press the mandrel (12), with the wires (18-18) seated in the mandrel channels (14-14), against a IDC contact block (22) to engage each wire with an end (30) of a corresponding IDC contact (24) to accomplish attachment. As the wires (18-18) are pressed into the mandrel channels (14-14), a blade (106) severs the excess portion of each wire to facilitate attachment of the wires to the contacts.
