Abstract

An electric wire with terminal includes: an electric wire including a core wire having a plurality of element wires, and a covering that covers the core wire in a state in which an end portion of the core wire is exposed; and a crimp terminal including a core wire crimping portion crimped to a part of the end portion of the core wire on the covering side, and a swaging portion swaged to a part of the end portion of the core wire closer to a distal end than the core wire crimping portion. The core wire has a cutting surface formed by cutting a part of the element wires. The cutting surface is adjacent to the swaging portion, and is opposed to a side surface of the swaging portion in an axial direction of the electric wire. Adjacent element wires are bonded at the cutting surface.

First claim

What is claimed is:

1 . An electric wire with terminal, comprising:
an electric wire including a core wire having a plurality of element wires, and a covering that covers the core wire in a state in which an end portion of the core wire is exposed; and a crimp terminal including a core wire crimping portion crimped to a part of the end portion of the core wire on the covering side, and a swaging portion swaged to a part of the end portion of the core wire closer to a distal end of the core wire than the core wire crimping portion, wherein the core wire has a cutting surface formed by cutting a part of the element wires, the cutting surface is adjacent to the swaging portion, and is opposed to a side surface of the swaging portion in an axial direction of the electric wire, and adjacent ones of the element wires are bonded at the cutting surface.

2 . The electric wire with terminal according to claim 1 , wherein
a distal end of the element wire is sheared and deformed in a direction toward a bottom portion of the swaging portion along the cutting surface.

3 . The electric wire with terminal according to claim 1 , wherein
the cutting surface is a surface formed by cutting the element wire by the swaging portion.

4 . The electric wire with terminal according to claim 2 , wherein
the cutting surface is a surface formed by cutting the element wire by the swaging portion.

5 . An electric wire with terminal, comprising:
an electric wire including a core wire having a plurality of element wires, and a covering that covers the core wire in a state in which an end portion of the core wire is exposed; and a crimp terminal including a core wire crimping portion crimped to a part of the end portion of the core wire on the covering side, and a swaging portion swaged to a part of the end portion of the core wire closer to a distal end of the core wire than the core wire crimping portion, wherein a swaging piece of the core wire crimping portion and a swaging piece of the swaging portion are integrally formed, the core wire has a cutting surface formed by cutting a part of the element wires, the cutting surface is covered by the swaging portion, and adjacent ones of the element wires are bonded together at the cutting surface.

6 . The electric wire with terminal according to claim 2 , wherein
a distal end of the element wire is sheared and deformed in a direction toward a bottom portion of the swaging portion along the cutting surface.

7 . The electric wire with terminal according to claim 3 , wherein
the cutting surface is a surface formed by cutting the element wire by the swaging portion.

8 . The electric wire with terminal according to claim 6 , wherein
the cutting surface is a surface formed by cutting the element wire by the swaging portion.

9 . A method of manufacturing an electric wire with terminal, the electric wire including a core wire having a plurality of element wires, and a covering that covers the core wire in a state in which an end portion of the core wire is exposed, the method comprising steps of:
crimping a core wire crimping portion of a crimp terminal to a part of the end portion of the core wire on the covering side; and cutting a part of the element wires by a swaging portion by swaging the swaging portion of the crimp terminal to a part of the end portion of the core wire closer to a distal end than the core wire crimping portion.
