Abstract

Abstract An insulation displacement connector is described for making contact to the wires of a flat multiconductor insulation cable wherein the wires are spaced by 0.050 inch or less, and may be as low as 0.025 inch. An insulation housing contains two rows of identical contacts which are easily loaded into the openings of the housing. The contacts have cable insulating shearing tines extending beyond one surface of the housing and nose ends for receiving header pins or other mating members at the outer surface of the housing. The tines of the contacts in one row of openings are staggered from those of the adjacent row by the distance between wires in the connecting cable. A metal latch secures a cover to the insulator base and a special metal strain relief strap is fixed to the cover to hold the cable in position against strain forces which would tend to pull the cable away from its connection with the tines. The overall design is such that the socket and header can be disconnected from one another without destroying the assembly.
