ABSTRACT:
The present invention is directed to a method of making a shielded cable harness having a plurality of discrete wires whose opposite ends are terminated to a pair of electrical connector housings, and a drain wire terminated to at least one of said housings. In a preferred embodiment, the method includes the steps of manufacturing a harness composed of a plurality of discrete wires of predetermined length arranged generally in parallel fashion between a pair of housings, with one having a drain wire. Such harness, in this preliminary state, may consist of plural discrete wires with individual leads at the respective wire ends for insertion into appropriate cavities of a connector housing, or the discrete wires may be directly inserted into a housing such as by an insulation displacement termination. In either case, the discrete wires, typically arrayed in parallel fashion, are twisted in a first direction to spirally arrange such wires, followed by twisting the drain wire in an opposite direction around said spirally arranged discrete wires. The method is completed by placing a jacket of insulative material about said twisted wires, where said jacket has been provided with an inner metallic layer for contact with said drain wire, and applying an insulative sleeve where said discrete wires project from said jacket. In its most preferred embodiment, said jacket comprises an elongaed "C" shaped member having a laminated metallic layer on the inside thereof.
