Abstract

A terminal-equipped electric wire, a connector including the terminal-equipped electric wire and a manufacturing method of the connector are provided. The terminal-equipped electric wire includes an electric wire including a conductor core wire formed of a conductor material and a terminal formed of a composite metal material in which a plurality of types of metal materials are clad-bonded with each other. The terminal includes a first connection portion and a second connection portion, each of which is formed of a metal material of respective one of the plurality of types of metal materials. The conductor core wire is electrically connected to one of the first and second connection portions, the one corresponding to the conductor material forming the conductor core wire.

First claim

What is claimed is:

1. A terminal-equipped electric wire comprising:
an electric wire including: a conductor core wire formed of a conductor material; and a terminal formed of a composite metal material in which a plurality of types of metal materials are clad-bonded with each other,
wherein the terminal includes a first connection portion and a second connection portion, each of which is formed of a metal material of a respective one of the plurality of types of metal materials,
wherein the conductor core wire is electrically connected to and mounted onto the first connection portion when the conductor material of the conductor core wire corresponds to the metal material of the first connection portion, and the conductor core wire is electrically connected to and mounted onto the second connection portion when the conductor material of the conductor core wire corresponds to the metal material of the second connection portion.

2. The terminal-equipped electric wire according to claim 1 ,
wherein the first connection portion and the second connection portion are arranged at positions offset from each other.

3. The terminal-equipped electric wire according to claim 1 ,
wherein the plurality of types of metal materials include copper, a copper alloy, aluminum and an aluminum alloy;
wherein the terminal further includes a contact portion configured to be electrically connected to a mating terminal;
wherein the first connection portion is connected to the contact portion;
wherein the second connection portion is clad-bonded to the first connection portion; and
wherein the contact portion and the first connection portion are formed of copper or a copper alloy and the second connection portion is formed of aluminum or an aluminum alloy.

4. A connector including:
the terminal-equipped electric wire according to claim 1 ; and
a housing configured to accommodate the terminal-equipped electric wire.

5. The connector according to claim 4 ,
wherein the housing includes: a terminal holding portion configured to hold the terminal; and a displacement restraining portion configured to restrain displacement of the electric wire relative to the terminal.

6. A manufacturing method for manufacturing the connector including the terminal-equipped electric wire according to claim 1 and a housing configured to accommodate the terminal-equipped electric wire, the manufacturing method including:
holding the terminal in the housing such that at least a part of each of the first and second connection portions is exposed;
selecting one connection portion out of the first and second connection portions which corresponds to the conductor material forming the conductor core wire of the electric wire to be used; and
electrically connecting the conductor core wire of the electric wire to be used to the one connection portion.

7. The manufacturing method according to claim 6 ,
wherein the housing includes: a first component including a terminal holding portion configured to hold the terminal; and a second component including a displacement restraining portion configured to restrain displacement of the electric wire connected to the terminal relative to the terminal; and
wherein the manufacturing method further includes: attaching the first component and the second component to each other.
