Abstract

A terminal integrally includes a connecting portion connected to a mating terminal, a cover fixing portion that is positioned rearward of the connecting portion and fixes a cover of an electric wire including a conductor core wire and the cover covering the conductor core wire, and a conductor fixing portion that is positioned between the connecting portion and the cover fixing portion and fixes the conductor core wire exposed from the electric wire.

Claims

1. A terminal integrally comprising:

a connecting portion connected to a mating terminal;

a cover fixing portion that is positioned rearward of the connecting portion and fixes a cover of an electric wire including a conductor core wire and the cover covering the conductor core wire; and

a conductor fixing portion that is positioned between the connecting portion and the cover fixing portion and fixes the conductor core wire exposed from the cover of the electric wire,

wherein the terminal is connected to a front end of the electric wire,

wherein the terminal is made of a plate member and extends in a front-rear direction,

wherein the conductor fixing portion includes an inclined portion extending obliquely to one side from the front-rear direction and having a through hole passing through in a thickness direction, and

wherein the conductor fixing portion is configured to fix the conductor core wire by pressing a predetermined portion of the conductor fixing portion to the other side opposite to the one side in a state that the conductor core wire is inserted into the through hole so that an end edge of the through hole bites the conductor core wire.

2. The terminal according to claim 1,

wherein the conductor fixing portion integrally includes a first inclined portion, a second inclined portion, and a coupling portion,

wherein the first inclined portion is connected to a rear end portion of the connecting portion, extends obliquely to the one side and a rear side from the rear end portion of the connecting portion, and includes a first through hole passing through in the thickness direction,

wherein the second inclined portion is connected to a front end portion of the cover fixing portion, extends obliquely to the one side and a front side from a front end portion of the cover fixing portion, and includes a second through hole passing through in the thickness direction,

wherein the coupling portion connects extended end portions of the first inclined portion and the second inclined portion to each other, and

wherein the conductor fixing portion is configured to fix the conductor core wire by pressing the coupling portion to the other side in a state that the conductor core wire of the electric wire is inserted into the first and second through holes so that the end edges of the first and second through holes bite the conductor core wire.

3. A method of connecting the electric wire to the terminal according to claim 1, the method comprising:

accommodating the terminal in a terminal accommodating portion of a housing;

inserting the conductor core wire exposed from the cover of the electric wire into the through hole of the terminal accommodated in the terminal accommodating portion; and

pressing the predetermined portion of the conductor fixing portion to the other side in a state that the conductor core wire is inserted into the through hole and making the end edge of the through hole to bite the conductor core wire so as to fix the conductor core wire to the conductor fixing portion.
