ABSTRACT:
An electrical contact, for use in pin and socket type connectors, is fabricated as a unitary, composite body of metal and plastic. The contact (10) comprises a tubular body (12) having a wire receiving end (16) and a mating end (14). The composite tubular body (12) includes a sleeve (18) of wire cloth which is impregnated to form multiple islands (32) of plastic between the wires (34) on the internal surface and a plastic jacket (24) on the external surface. The contact fingers (22) are surrounded by a plastic hood (40) which provides a closed entry (42) for guiding a mating pin contact (44). The socket contact (10) is fabricated by stamping wire cloth to form a sleeve blank (18') and rolling the blank to form the sleeve (18). The sleeve (18) is fitted with core members (60) and (62) and placed in a mold cavity for injection molding of the plastic.
