US Classification:

Abstract:

This invention relates to a specific type of multi-conductor cable comprising a plurality of insulated wire conductor pairs, each of said insulated conductor pairs having alternating twist and straight portions and having alignment means for precisely aligning both the twisted portions and straight portions of said insulated conductor pairs in a predetermined, laterally spaced, relationship with respect to each other. The alignment means of the multi-conductor calbe of this invention comprises a laminated plastic sheet, initially formed from first and second plastic sheets or films, the laminated film having (a) a plurality of precisely spaced encapsulating ducts formed therein, each encapsulating duct containing either an individual, insulated, straight portion of a conductor or an insulated conductor twisted pair and (b) nip areas extending laterally between, and joining, each of said precisely spaced encapsulating ducts. The precisely spaced intermittent straight portions provide easy, mass termination sites and do not appreciably affect the electrical characteristics of the multi-conductor cable.
