Abstract

In a structure of connection of a connector terminal 10 connected to an electric wire whose core wire is covered with a outer cover, the connector terminal has a barrel portion for crimping the end of the electric wire and an electric connection portion electrically connected to a mating terminal. The outer cover of the electric wire is cut and separated in the vicinity of the end portion of the electric wire and displaced to expose the core wire. The separated portion of the outer cover displaced toward the end portion of the electric wire, an exposed portion of the core wire, and a portion of the electric wire covered with the outer cover are crimped to the barrel portion of the connector terminal.

Claims

1. A structure for connection, comprising:

an electric wire whose conductor is covered with an outer cover; and

a connector terminal connected to the electric wire;

wherein the connector terminal has a barrel portion for crimping an end portion of the electric wire and an electric connection portion to be electrically connected to a mating terminal;

wherein the outer cover is cut and separated in a vicinity of the end portion of the electric wire, and a separated portion of the outer cover is displaced toward the end portion so as to expose the conductor; and

the separated portion of the outer cover displaced toward the end portion of the electric wire, an exposed portion of the conductor, and a portion of the electric wire covered with the outer cover are crimped to the barrel portion of the connector terminal in a state that the exposed portion and its neighborhood of the conductor are completely sealed.

2. A method for connecting a connector terminal to an electric wire, in which the connector terminal has a barrel portion for crimping an end portion of the electric wire whose conductor is covered with an outer cover and an electric connection portion electrically connected to a mating terminal, the method comprising:

cutting and separating the outer cover in a vicinity of the end portion of the electric wire;

displacing a separated portion of the outer cover toward the end portion so as to expose the conductor; and

crimping the separated portion of the outer cover displaced toward the end portion of the electric wire, an exposed portion of the conductor, and a portion of the electric wire covered with the outer cover to the barrel portion of the connector terminal in a state that the exposed portion and its neighborhood of the conductor are completely sealed.
