CRIMP TERMINAL AND MANUFACTURING METHOD OF THE SAME, WIRE ASSEMBLY, AND WIRE HARNESS

摘要

In a manufacturing method of an aluminum wire crimp terminal formed by a base material made of a copper-based metal, at the step of forming an intermediate worked material having an unfolded shape of the crimp terminal, fine recessed parts for promoting the adhesive performance of the crimp terminal against a conductor of the wire are formed on a plate-body surface forming an inner face of a conductor crimping part of the intermediate worked material. Subsequently, a thin-film surface layer made of an aluminum-based metal is formed on at least the plate-body surface. Finally, the intermediate worked material is bent to a prescribed terminal shape.

主权项

1. A crimp terminal, comprising:
a conductor crimping part whose base material is made of a first metal and which is to be crimped to a conductor of an electric wire, the conductor being made of a second metal; a plurality of fine recessed parts for promoting the adhesive performance of the conductor crimping part against the conductor, the fine recessed parts being formed, after an intermediate worked material having an unfolded shape of the crimp terminal has been formed by pressing either the base material made of the first metal and shaped like a flat plate or a material where a primary layer is formed on the surface of the base material, on a plate-body surface as an inner face of the conductor crimping part of the intermediate worked material; a thin-film surface layer made of the second metal, which is formed on at least the plate-body surface of the intermediate worked material after forming the fine recessed parts, the thin-film surface layer to be brought into contact with the conductor.
