Abstract

A molded electric wire is composed of a conductor wire, an insulating member coating a circumference of the conductor wire, including a thermoplastic polyurethane, and having an arithmetic average surface roughness of not smaller than 5 μm and not greater than 100 μm, and a molded resin part directly coating a terminal of the insulating member.

First claim

What is claimed is:

1 . A molded electric wire, comprising:
a conductor wire; an insulating member coating a circumference of the conductor wire, the insulating member comprising a thermoplastic polyurethane, and having an arithmetic average surface roughness of not smaller than 5 μm and not greater than 100 μm; and a molded resin part directly coating a terminal of the insulating member.

2 . The molded electric wire according to claim 1 , wherein the molded resin part comprises a polyamide or a polybutylene terephthalate.

3 . The molded electric wire according to claim 1 , wherein the insulating member further comprises a matting agent.

4 . The molded electric wire according to claim 3 , wherein the matting agent comprises an inorganic compound powder or crosslinked polymer particles.

5 . The molded electric wire according to claim 1 , wherein the insulating member comprises an insulator, which directly coats the circumference of the conductor wire.

6 . The molded electric wire according to claim 1 , wherein the insulating member comprises a sheath, which indirectly coats the circumference of the conductor wire.

7 . The molded electric wire according to claim 5 , comprising a multiplicity of electrically insulated wires each comprising the conductor wire and the insulator,
wherein terminals of the multiplicity of electrically insulated wires are being coated by the molded resin part together.

8 . The molded electric wire according to claim 7 , including a sheath coating the circumferences of the multiple of electrically insulated wires together,
wherein the molded resin part is not in contact with the sheath.

9 . The molded electric wire according to claim 1 , wherein the airtightness inside the molded resin part is maintained, even after 1000 cycles of heat shock testing where one cycle of the heat shock testing refers to being left unattended at a temperature of −40 degrees Celsius for 30 minutes and left unattended at a temperature of 125 degrees Celsius for 30 minutes.
