Patent ID: 8419454

Claim:
A card connector adapted for receiving a micro-SIM (micro-Subscriber Identification Module) card therein, comprising: an insulating housing having a base board, two opposite sides of the base board extending upward to form two side walls, a rear end of the base board extending upward to form a rear wall connecting between the two side walls, a receiving space being formed among the base board, the two side walls and the rear wall, the base board defining two rows of openings vertically penetrating therethrough, each row of the openings being arranged at regular intervals along a transverse direction; a plurality of terminals disposed in the insulating housing with contact portions thereof projecting upward into the receiving space through the corresponding openings; an ejection mechanism including a sliding block, an elastic element and a guide pin of an inverted-U shape, the sliding block having a base body and a pushing body extending sideward from a rear of one side of the base body, the elastic element being telescopically restrained between a rear of the base body and an inner face of the rear wall to make the sliding block slidably assembled in one side of the insulating housing with the pushing body projecting into the receiving space, one end of the guide pin being fastened in a front end of the base body and the other end of the guide pin being slidably located in the one side of the insulating housing; a tray slidably positioned in the receiving space of the insulating housing and against a front of the pushing body of the sliding block, the tray being of a rectangular frame shape with an accommodating space being formed therein, two bottoms of two facing sidewalls of the accommodating space protruding towards each other to form two supporting boards for propping up the micro-SIM card in the accommodating space, the contact portions of the terminals passing through an interval between the supporting boards to electrically contact with the micro-SIM card, a top of the tray defining at least one buckling groove; and a shielding shell covered on the insulating housing, a top of the shielding shell defining at least one gap, a limiting tab being defined in the gap and having a flexible arm extending forward from a rear sidewall of the gap, and a buckling portion arched downward from a free end of the flexible arm; wherein the tray pushes the pushing body rearward to drive the sliding block rearward or forward under a cooperation of the guide pin and the elastic element to make the buckling portion buckled in the buckling groove or apart from the buckling groove so as to lock the tray together with the micro-SIM card in the receiving space of the card connector or eject the tray together with the micro-SIM card out of the card connector.
