1. Field of the Invention
This specification relates to a terminal and a wire with terminal.
2. Description of the Related Art
Japanese Utility Model Application No. H07-36364 discloses a terminal connected to a wire. The terminal includes a barrel to be crimped to the wire, and the barrel is formed with through holes. The terminal is crimped to the wire by fastening the barrel so that a folded part of a conductor is pressed into contact with a bottom part of the terminal by an insulation coating.
In the above configuration, if a cross-sectional area of the conductor becomes smaller, a force for holding the conductor is reduced and a force exerted to the insulation coating gradually increases when the wire is pulled. Then, edge parts of the through holes of the barrel easily bite into the insulation coating to tear the insulation coating. Although the barrel is crimped to the insulation coating in this way, the crimping of the insulation coating does not contribute to an improvement in the impact resistance of the wire at all and the insulation coating could not compensate for a reduction of the conductor holding force.
