Abstract

When a crimped structure of an electrical wire to a terminal is formed with an electrical wire crimped to a crimp terminal fitting, first, a coating on a leading end of the electrical wire is peeled off to expose core wires, and the leading ends of the core wires are processed into a conical shape so as to be tapered over the entire circumference to form a tapered part. Next, the electrical wire is arranged in an electrical wire barrel such that the core wires of the electrical wire with the coating peeled off are accommodated in a core wire barrel. At this time, a bottom of the conical shape on the leading ends of the core wires is adapted to be accommodated in the core wire barrel. The core wires are swaged by a crimping piece of a core wire crimping part.

First claim

1 . A method for crimping an electrical wire to a terminal, comprising:
forming a tapered part by processing leading ends of peeled-off core wires of the electrical wire so as to be tapered over the entire circumference; and crimping the electrical wire to the terminal.

2 . The method for crimping the electrical wire to the terminal according to claim 1 , wherein
the electrical wire is crimped to the terminal with the electrical wire arranged in a barrel such that a bottom of the tapered part is accommodated in the barrel of the terminal.

3 . The method for crimping the electrical wire to the terminal according to claim 1 , wherein
the leading ends of the peeled-off core wires of the electrical wire are processed into a stepped shape over the entire circumference to form the tapered part.

4 . The method for crimping the electrical wire to the terminal according to claim 1 , wherein
the leading ends of the peeled-off core wires of the electrical wire are processed into a conical shape over the entire circumference to form the tapered part.

5 . The method for crimping the electrical wire to the terminal according to claim 2 , wherein
the leading ends of the peeled-off core wires of the electrical wire are processed into a stepped shape over the entire circumference to form the tapered part.

6 . The method for crimping the electrical wire to the terminal according to claim 2 , wherein
the leading ends of the peeled-off core wires of the electrical wire are processed into a conical shape over the entire circumference to form the tapered part.
