Abstract
Abstract An insert molded multiple contact electrical connector comprising a molded insert of thermoplastic insulating material having a barrel shaped body which has a plurality of circumferentially spaced grooves and a plurality of cable grips. The cable grips are formed by semicircular grooves in parallel segments of a polygonal flange at one end of the barrel shaped body. A plurality of electrical contacts which are attached to a plurality of electric cables by core and insulation crimp wings are disposed in the grooves and the cable grips respectively to form a subassembly. An outer housing of thermoplastic insulating material is molded over the subassembly in a die which has a plurality of cable grip parts which cooperate with the respective cable grips of the molded insert to retain and seal around the electric cables individually and to space the electric cables from each other when the outer housing of thermoplastic insulating material is molded over the subassembly. The electrical contacts also have tangs which are disposed against the opposite end of the barrel shaped body between axially projecting lugs.
