Female terminal for connector

A female terminal for a connector comprising:

• an electric contact portion that is disposed at a front side of the female terminal for electrically connecting a male terminal on a mating connector;
• and
• an electric wire connection portion that is disposed at a rear side of the female terminal for electrically connecting an electric wire,
• wherein the electric contact portion includes:
• a cylindrical box portion into which the male terminal is inserted through a front end inlet;
• and
• an elastic contact spring which is provided in the box portion and is elastically deformed in a direction perpendicular to the insertion direction of the male terminal by being pushed by the male terminal when the male terminal is inserted into the box portion so as to hold the male terminal between the elastic contact spring and a peripheral wall of the box portion by an elastic reaction force caused by the elastic deformation;
• wherein the box portion is made in a cylindrical shape formed in such a manner that a roughly rectangular shaped metal plate is rolled and end edges of the metal plate are abutted with each other;
• wherein the elastic contact spring is formed by press processing a metal plate which is integrated with the metal plate from which the box portion is formed;
• wherein in the peripheral wall of the box portion, an abutment portion in which the end edges of the metal plate are abutted with each other is disposed at a wall portion which holds the male terminal together with the elastic contact spring;
• wherein a projection portion protruding toward the inside of the box portion is formed on the wall portion where the abutment portion is disposed, by press deforming the wall portion from the outside of the box portion in a concave shape;
• and
• wherein an apex of the projection portion serves as a contact portion with respect to the male terminal.
