Abstract

A terminal and connection structural body that can restrain galvanic corrosion occurring between a core wire of a covered electrical wire and a terminal formed of different types of metal, and that can ensure conductive function. The terminal includes a box part as a connection part connected to another terminal and a wire barrel part as a crimping part crimp-connected to a covered electrical wire. All of a non-contact part, including an end surface as a cut surface upon blanking a metal member, is covered with a resin covered part, where the non-contact part is other than a contact part with another terminal, a non-covered part, and a contact part with an end part as an exposed part of a core wire of a covered electrical wire, a non-covered part.

First claim

1 . A terminal including a connection part connected to another terminal and a crimping part crimp-connected to a covered electrical wire, wherein substantially all of a non-contact part, including a cut end surface upon blanking a metal member, is covered with a resin covered part, where the non-contact part is other than a contact part with the other terminal and a contact part with an exposed part of a conductor of the covered electrical wire.

2 . The terminal according to claim 1 , wherein the crimping part is comprised of a wire barrel part and an insulation barrel part.

3 . The terminal according to claim 1 , wherein the resin covered part is formed by using a pulse spray method.

4 . The terminal according to claim 1 , wherein the resin covered part is formed to cover equal to or more than 95% of a terminal surface.

5 . A connection structural body, comprising: the covered electrical wire connected to the crimping part of the terminal according to claim 1 .

6 . A method of manufacturing a terminal including a connection part connected to another terminal and a crimping part crimp-connected to a covered electrical wire, wherein substantially all of a non-contact part, including a cut end surface upon blanking a metal member, is covered with resin, where the non-contact part is other than a contact part with the other terminal and a contact part with an exposed part of a conductor of the covered electrical wire.

7 . The method of manufacturing a terminal according to claim 6 , wherein the step of being covered with resin is coating resin fluid by spraying at a constant interval.

8 . The method of manufacturing a terminal according to claim 6 , wherein the step of being covered with resin is performed while the contact part is being masked prior to being covered with resin.
