1. An electrical connector, comprising:
- an electric wire having a conductor made of one of aluminum and an aluminum alloy, and an insulating coating covering the conductor; and
a terminal having a connecting portion that is compression heated and to which an exposed conductor of the electric wire is connected, the exposed conductor being exposed at a terminal end of the electric wire, whereinthe connecting portion is formed by compressing while heating a tubular part of the terminal in a condition in which the exposed conductor is inserted into the tubular part and at a temperature between 300°
C. and 500°
C., andwhereina cross-sectional area of the connecting portion is 30% to 70% of a cross-sectional area of a portion corresponding to the connecting portion before the connecting portion is compression heated.

Abstract
An electric wire with a terminal includes an electric wire that has a conductor made of aluminum or aluminum alloy and an insulating coating covering the conductor, and a terminal that has a connecting portion to which an exposed conductor that is exposed at a terminal end of the electric wire is connected. The connecting portion is formed by compressing while heating a tubular part in a state in which the exposed conductor is inserted into the tubular part, the tubular part being provided on the terminal and being capable of allowing the exposed conductor to be inserted thereinto.

5. A method of manufacturing an electrical connector, the method comprising:
-
providing an electric wire having a conductor and an insulating coating covering the conductor, the conductor being made of one of aluminum and an aluminum alloy, providing a terminal having a connecting portion to which an exposed conductor of the electric wire is connected, the exposed conductor being exposed at a terminal end of the electric wire, inserting the exposed conductor into a tubular part of the terminal; and
, thereafter,forming the connecting portion by compressing while heating the tubular part at a temperature between 300°
C. and 500°
C., andwherein the connecting portion is formed by compressing the connecting portion to have a cross-sectional area of 30% to 70% of a cross-sectional area of a portion corresponding to the connecting portion before compression. - View Dependent Claims (6, 7, 8, 9)
