Electric wire with terminal and method for producing the same

摘要

An electric wire with a terminal may include an insulated electric wire that may include an insulating coating of polyolefin based resin, an adhesive layer that may be formed over an entire circumference of a surface of the insulating coating, and a waterproofing resin portion that may be formed by insert molding. The waterproofing resin portion may cover a region between the adhesive layer of the insulated electric wire and a portion where the metal terminal is connected to a core wire. The adhesive layer may include a composition of a copolymer of ethylene and glycidyl methacrylate and a phenol based curing agent. The waterproofing resin portion may include aromatic nylon.

1. An electric wire with a terminal comprising:
an insulated electric wire comprising:
a conductive core wire; andan insulating coating of polyolefin based resin that covers a circumference of the core wire; a metal terminal electrically connected to the core wire at an end portion of the insulated electric wire; an adhesive layer that comprises a composition of a copolymer of ethylene, glycidyl methacrylate, and a phenol based curing agent, and is formed over an entire circumference of a surface of the insulating coating at an end portion of the insulated electric wire; and a waterproofing resin portion that comprises aromatic nylon and is formed by insert molding using, as an insert portion, a protected region, wherein the protected region comprises a region that is at least disposed between a portion of the insulated electric wire where the adhesive layer is formed and a portion where the metal terminal is connected to the core wire, the waterproofing resin portion covers protected region, and the adhesive layer bonds an outside surface of the insulating coating to an inside surface of the waterproofing resin portion.
