Abstract
A socket assembly is provided at the end of a heavy electrical cable which includes sockets designed to be pushed into connection with pins on an aircraft, to pass current between them, which provides low resistance to avoid heating while also providing a high withdrawal force to prevent the weight of the cable end from pulling it out of connection with the aircraft pins. The sockets include pin-receiving holes, with grooves in the hole walls for holding multi-beam contactors. Each contactor includes a pair of spaced circular bands and a plurality of beams extending between the bands and bowed radially inwardly to resiliently contact the pin. A socket includes two of such contactors, whose beams engage the plug at two locations spaced along the hole to more uniformly guide the pin along the hole and provide low contact resistance and a high resistance to withdrawal. The contactors are initially plastically deformed when the pin is first inserted, to assure that a high withdrawal force is achieved.
