Abstract
Abstract A connector has an insulating substrate (3) having a plurality of holes (6) and a desired first circuit pattern on it. Female contactors (2) are fixed around the edge of each hole (6) and have an opening whose edge is inwardly of the periphery of the hole, said female contactors being electrically connected to said first pattern. A male contactor component comprises an insulating substrate having a desired second circuit pattern thereon and a plurality of male contactor pins (1) fixed to the substrate and electrically connected to said second pattern, said pins being located in positions corresponding to the openings of the respective female contactors (2). The female contactors are made of a thin film of a shape memory alloy and the edge of each of the female contactors is given, before insertion of each of the male contactor pin, a shape memory such that the contactor (2) tends to return to a position to close or block the opening when said contactor is subjected to a temperature above the martensitic transition temperature. The pin (3) can thus be inserted at low temperature with little or no force, and yet is firmly gripped in service.
