ABSTRACT:
A locking receptacle for electrical connectors includes a premold which holds the wire contacts in position and prevents insulation from overflowing into the contacts during molding. The premold is a cylindrical form of rigid high melting point thermoplastic insulating material having differently shaped passages and slots for a plurality of female contacts and connecting leads and includes an end closure member. The elements are assembled together, mounted in a mold and overmolded with a lower melting point resilient insulation covering in a simplified molding process to form an integral water-tight unit.
