ABSTRACT:
A sealed electrical connector 10 has first and second insulated body members 12, 38 and a plurality of terminal members. At least one body member 12 includes a first thermoplastic portion 14 and a second thermoset portion 24 formed in a common mold. The material for the thermoplastic portion 14 has a melting temperature T.sub.1 and the material for the thermoset portion 24 has a curing temperature T.sub.2 wherein T.sub.2 <T.sub.1. The thermoplastic material is injected into a first mold cavity and is cooled to a temperature lower than T.sub.1 and higher than T.sub.2 to form a solid first body portion. An internal mold portion within the closed mold is moved to form an additional mold cavity adjacent the first mold cavity. The configuration of the second mold cavity is at least partially defined by part of a surface of the first body portion. The thermoset material is injected into the additional cavity at a temperature lower than T.sub.2. The thermoset material body member is cured by heat transmitted across the common interfacial surface 25 by the cooling of the thermoplastic material and the mold 72 in which the connector is formed. The thermoplastic material preferably is relatively rigid and forms an outer body section 14 and the thermoset material is relatively resilient and forms an inner body section 24 of the connector member.
