Electronic card connector having improved grounding plate
First Claim
1. An IC card connector for mounting on a printed circuit board, comprising:
- an insulative housing including a space for accommodating an IC card and a cross bar, the cross bar having a mating surface against which the IC card abuts and a front surface opposite the mating surface;
a plurality of conductive terminals secured in the cross bar, each of terminals including an engaging end protruding into the space from the mating surface for mating with the IC card, and a mounting end extending from the front surface for being soldered on the printed circuit board; and
a conductive grounding plate secured on the cross bar and having at least one soldering finger for being soldered on the printed circuit board;
wherein each soldering finger is soldered at a position wherein the distance between each soldering finger and the mating surface is less than the distance between the mounting ends of the terminals and the mating surface;
wherein the at least one soldering finger and the mounting ends of the terminals are soldered at respective different sides of the cross bar;
wherein the grounding plate has at least one bridge abutting against the mating surface of the cross bar, and the at least one soldering finger extends from the bridge toward the space;
wherein the grounding plate further includes a base extending over, the space and a plurality of tongues protruding from the base into the space for engaging with the IC card.

Abstract
An IC card connector comprises a dielectric housing (10), a number of terminals (20), a conductive grounding plate (40), and a metal shield (30) with an actuating rod (50). The housing has a cross bar (13) with a mating surface (11) against which an inserted IC card abuts. The terminals have mounting ends (22) protruding forwardly from the cross bar. The grounding plate includes a base (45), a flange (42) for securing the grounding plate on the housing, a pair of bridges (41) abutting against the mating surface, and a number of soldering fingers (44) projecting rearwardly from the mating surface. The soldering fingers and the mounting ends are soldered to a printed circuit board at rear and front sides of the cross bar, respectively, thereby facilitating inspection and re-soldering of the mounting ends.
