Abstract

In a connector terminal connected to an electric wire in which a conductor is covered with an outer cover, the terminal includes a barrel portion that is exposed from the outer cover and is to be crimped to the conductor coated with a covering, and an electrical connection portion electrically connected to a mating terminal, wherein a trench or a projection that is provided along a direction perpendicular to an axis of the electric wire are formed in an inner surface of the barrel portion, and a depth of the trench or a projecting dimension of the projection is made smaller than a covering thickness of the covering.

Claims

1. A connector terminal connected to an electric wire in which a conductor is covered with an outer cover, the terminal comprising:

a barrel portion that is exposed from the outer cover and is to be crimped to the conductor coated with a covering; and

an electrical connection portion electrically connected to a mating terminal,

wherein a trench or a projection that is provided along a direction perpendicular to an axis of the electric wire are formed in an inner surface of the barrel portion; and

a depth of the trench or a projecting dimension of the projection is made smaller than a covering thickness of the covering.

2. The connector terminal according to claim 1, wherein the barrel portion includes a sealing piece that seals a forefront of the conductor when the conductor is crimped.

3. The connector terminal according to claim 1, wherein the barrel portion is divided into a core wire crimping portion crimping the conductor and an outer cover crimping portion crimping the outer cover.

4. The connector terminal according to claim 2, wherein the barrel portion is divided into a core wire crimping portion crimping the conductor and an outer cover crimping portion crimping the outer cover.
