Abstract:
1. A card connector for insertion of an electrical card comprising: an insulative housing defining a receiving space for insertion of the electrical card along a front-to-back direction; a plurality of contacts retained in the insulative housing and protruding into the receiving space for electrical connection to the electrical card; a metal spring member having an arcuate locking arm protruding toward the receiving space for retaining the electrical card in the receiving space; and a metal guiding member having a guiding portion extending primarily along the front-to-back direction for guiding a lateral side of the electrical card and a resisting portion extending from a back end of the guiding portion for resisting a front free end portion of the locking arm outwardly; wherein the insulative housing comprises a bottom wall located under the receiving space, a rear wall extending upwardly from a rear end of the bottom wall, and a first side wall extending upwardly from a lateral side of the bottom wall and connecting with the rear wall, the first side wall has a cavity passing therethrough along a transverse direction and communicating with the receiving space for accommodating the locking arm to be movable along the transverse direction, the first side wall is separated by the cavity into a front first portion and a back second portion; wherein the spring member has an L-shaped retaining portion retained into an L-shaped retaining slot formed on the insulative housing, the locking arm extends from a front end of the L-shaped retaining portion; wherein the insulative housing comprises a top wall opposed to the bottom wall and space apart from the top wall with the receiving space, the L-shaped retaining portion comprises a first portion extending along the transverse direction and retained in a first slot formed between the top wall and the rear wall, and a second portion extending along the front-to-back direction and retained in a second slot formed between the top wall and the second portion of the first side wall, the first slot and the second slot form as the L-shaped retaining slot; wherein the top wall has a first opening communicating with the second slot for accommodating the locking arm to be assembled into the insulative housing; wherein the insulative housing further comprises a second side wall opposite to the first side wall and extending upwardly from the other lateral side of the bottom wall, the card connector further comprises a metal shell shielding the insulative housing, the shell has a top plate covering the top wall and a spring tab bending downwardly from the top plate, the spring tab has a retaining tab retained in a slit formed between the top wall and the second side wall, and a clamping arm extending from the retaining tab for resisting the other lateral side of the electrical card; wherein the top wall has a second opening communicating with the slit for accommodating the clamping arm to be assembled into the insulative housing, the second side wall has a cutout passing therethrough along the transverse direction and communicating with the receiving space for movably accommodating the clamping arm, and a stopping portion located at front of the cutout for resisting a distal end of the spring tab outwardly so as to prevent the clamping arm from inwardly over deformation.
