Patent ID: 7357665

Claim:
A battery connector, located on an electric board, comprising: a dielectric housing, having a front surface, a rear surface, an upper surface, and a lower surface, terminal grooves defined from the front surface to the rear surface and through the upper surface, the bottoms of the terminal grooves extending toward two sides thereof to form a fixing groove respectively, the tops of two sidewalls of each terminal groove extending inwardly respectively to form a pair of withstanding beams, the front end of the withstanding beam being cut off to form a gap, the front of the lower surface defines at least one receiving groove located between the two adjacent terminal grooves and penetrating through the front surface; electric terminals, accepted in the terminal grooves of the dielectric housing, having a base accepted in the fixed groove of the dielectric housing, the rear end of the base bending upwardly to form a spring portion, a contact portion extending from one end of the spring portion and partly upward projecting out of the terminal grooves, the middle of the front end of the base bending upwardly to form a welded tail portion, the welded tail portion leaning inwardly, two project edges extending outwardly from two sides of the top of the welded tail portion; and at least one ground spring received in the receiving groove, the ground spring having a body with a U shape, the body including a bottom arm, a front arm and a rear arm extending upwardly from the front and the rear of the bottom arm respectively, a fixed pillar extending forwardly from the front arm of the body and being vertical with respect to the front arm, the fixed pillar being inserted in the electric board, a cam being formed at the rear arm of the body to interfere with the receiving groove for fixing the ground spring in the receiving groove; wherein the welded tail portion is located in the front end of the terminal groove with a part exposed outside the front surface, and the project edges of the electric terminal are located in the gaps and against the front walls of the withstanding beams.
