Abstract

A terminal is to be connected to an electric wire including a conductor core wire and a sheath covering the conductor core wire. The terminal includes a connection portion and a conductor fixing portion which is located rearward of the connecting portion and configured to fix the conductor core wire exposed from the electric wire. The connection portion and the conductor fixing portion are integrally formed to each other and are extended in a front-rear direction. The conductor fixing portion has through holes penetrating in a thickness direction of the conductor fixing portion. An end edge portion of each of the plurality of through holes on an outer peripheral surface side of the conductor fixing portion is provided with a tapered portion that increases in diameter of the tapered portion toward an outer peripheral surface of the conductor fixing portion.

First claim

What is claimed is:

1. A terminal that is configured to be connected to a tip end of an electric wire including a conductor core wire and a sheath covering the conductor core wire, the terminal comprising:
a connection portion configured to be connected to a mating terminal; and
a conductor fixing portion located rearward of the connecting portion and configured to fix the conductor core wire exposed from the electric wire,
wherein the connection portion and the conductor fixing portion are integrally formed to each other and are extended in a front-rear direction;
wherein the conductor fixing portion has a plurality of through holes penetrating in a thickness direction which is substantially perpendicular to both of the front-rear direction and a width direction of the conductor fixing portion; and
wherein an end edge portion of each of the plurality of through holes on an outer peripheral surface side of the conductor fixing portion is provided with a tapered portion that increases in diameter of the tapered portion toward an outer peripheral surface of the conductor fixing portion.

2. The terminal according to claim 1 ,
wherein one of the plurality of through holes is located at a center in the front-rear direction and at a center in the width direction of the conductor fixing portion.

3. The terminal according to claim 1 ,
wherein the electric wire is mounted on an inner peripheral surface of the conductor fixing portion which is opposite to the outer peripheral surface.

4. An electric wire with a terminal, comprising:
the terminal according to claim 1 ; and
the electric wire whose conductor core wire is fixed by the conductor fixing portion via pressure contact,
wherein the conductor core wire enters into the tapered portions of the through holes and is in close contact with the tapered portions.
