ABSTRACT:
An electrically insulated cable having a sheath made of a material which is heat-fusible to a polyamide or polyester resin so that a highly waterproof joint portion can be formed between the cable and a housing simultaneously when the housing is injection-molded from a polyamide or polyester resin. The sheath is made from a crosslinked resin composition comprising a thermoplastic polyurethane elastomer and a thermoplastic polyester elastomer mixed together in a weight ratio of 80:20 to 20:80. A housing is provided around one end of the sheath of this cable by injection-molding polyamide or polyester engineering plastics to fuse the sheath to the housing, thereby hermetically sealing the interface between the cable and the housing. The sheath may be made from a crosslinked resin composition comprising a thermoplastic polyurethane elastomer and a thermoplastic polyamide elastomer mixed together in a weight of 80:20 to 10:90. It is possible to seal the cable to a housing made of polyamide engineering plastics.
