Terminal structure of wiring harness

摘要

A terminal structure of a wiring harness for automobile use having a profound anticorrosive effect. A terminal member is fixed to a terminal portion of a coated electric wire such that a crimping portion that the member includes at its one end is crimped around a coating portion of the wire in a terminal region of the wire. A resin member completely covers at least entire outer surfaces of an exposed region at an end portion of the crimping portion and its vicinal region, and is made from a material mainly containing a thermoplastic polyamide resin, and having a tensile lap-shear strength of lapped aluminums of 6 N/mm2 or more in accordance with the JIS K6850, an elongation of 100% or more in accordance with the ASTM D-1708, and a water absorption of 1.0% or less in accordance with the JIS K7209.

主权项

1. A terminal structure of a wiring harness for automobile use, the terminal structure comprising:
a coated electric wire comprising: a plurality of bare conductors; a coating portion with which the bare conductors are coated; and an exposed portion at an end of the electric wire, where the conductors are exposed; a terminal member that is fixed to the coated electric wire, and comprises a crimping portion at its one end that is fixed to the coated electric wire by being crimped around an outer surface of the coating portion of the electric wire in the vicinity of the exposed portion; and a resin member that covers at least an entire outer surface of an exposed region at an end portion of the crimping portion, and an entire outer surface of a region in the vicinity of the exposed region, wherein the resin member is made from a material that mainly contains a thermoplastic polyamide resin, and has a tensile lap-shear strength of lapped aluminums of 6 N/mm2 or more, which is measured in accordance with the JIS K6850; an elongation of 100% or more, which is measured in accordance with the ASTM D-1708; and a water absorption of 1.0% or less, which is measured in accordance with the JIS K7209.
