Abstract

The utility model discloses an electronic card connector, which contains an insulation body equipped with a base, a plurality of conductance terminals taken in the base, a grounding sheet which clings to an external surface of the base and a shadowing casing installed on the outside of the insulation body. The shadowing casing is equipped with a supporting sheet which stretches to the grounding sheet direction. The supporting sheet leans against the grounding sheet. By adding an elastic supporting sheet on the shadowing casing to lean against the grounding sheet, the electrostatic charge produced when the electronic card inserts into the accepted space can be removed timely through the grounding sheet so as to guarantee the quality of the signal transmission. And at the same time, the alteration of the design is small, which only needs to make a minor alteration on the base of the original shadowing casing structure and saves the design cost.
