IDC Connector For Cable To Card Termination

This article describes an IDC (Insulation Displacement Contact) connector which permits multi-wire cables to be mass terminated at printed circuit cards.

Fig. 1 shows a segment 10 of a printed circuit card with conductive lands or pads 12. An IDC connector 14 includes a plurality of individual contacts 16, 18, 20, 22. The connector 14 can be slid onto the printed circuit card 10, with each of the individual contacts being aligned with one of the conductive lands 12. Each of the contacts includes a forked arm 24. The arms 24 in the connector 14 are preferably staggered into two or more ranks. For example, in Fig. 1, the arms on contacts 16 and 20 are in one rank, while the arms of contacts 18 and 22 are in a second rank.

The arms receive the unstripped ends of individual wires in a multiwire round or flat cable. Each fork cuts the insulation on a wire to make electrical connection with the metal core. The connections between the individual wires and the individual contacts can be enhanced by localized heating of the contact/wire interfaces.

Fig. 2 is a stamped metal blank for the connector 14 prior to the time it is bent into the configuration shown in Fig. 1. The fold lines are represented by small, horizontal dashes. Individual connectors are joined by bridges 26 which are ruptured when the vertical arms are formed. The connectors are also joined at a selvage strip 28 which remains in place until the connector assembly...
