Abstract: A preformed electrical insulation displacement connector enabling electrical continuity between telecommunications equipment whose multiple electrical leads are commonly on a 0.085 inch pitch (center line distance between conductors) and other types of electronic equipment whose multiple electrical leads are commonly on a 0.050 inch pitch. A pair of 25 conductor arrays are preformed for rapid and facile assembly assuming upper and lower rows in an insulative housing. Contacts are mounted at the forward end of the housing so they assume the 0.085 inch pitch and can be engaged by a conventional multiple contact plug and bifurcated tails are mounted at the aft end of the housing to engagingly receive successive leads of a conventional ribbon cable which has a 0.050 inch pitch. If desired, the housing can accommodate a plural contact capacitor filter array adapted to be electrically engaged by the conductor arrays.

Abstract: A connector for terminating a coaxial cable is provided which includes a first insulation displacement contact for contacting the shield and a second insulation displacement contact for contacting the central conductor. The contacts are arranged on a support base in an axial sense corresponding to the axis of the cable defined by the central conductor. The process of terminating the coaxial cable comprises stripping the outer insulating jacket and shield from a small end portion of the cable and then inserting that portion into one of the contacts while an unstripped portion is inserted into the other of the contacts. The insulation displacement contacts pierce the insulation to make direct electrical contact to the respective shield or central conductor.
