Card connector

A card connector adapted for receiving an electronic card therein, comprising:

• an insulating housing having a base body, two opposite sides of the base body extending upward to form two side walls, the base body defining a plurality of terminal grooves of which each penetrates through a top of the base body, one side of the top of the base body being concaved downward to form a receiving trough adjacent to one side wall, a locking groove being opened downward in the top of the base body and connected with an inner side of the receiving trough opposite to the one side wall, a top of the one side wall defining a passage of which a front end passes sideward through the one side wall to communicate with a front end of the receiving trough;
• a plurality of terminals received in the terminal grooves of the insulating housing with top portions thereof being exposed to the top of the base body to electrically contact with the electronic card;
• an ejection mechanism including a sliding block slidably disposed in the receiving trough of the insulating housing, an elastic element received in the passage and clipped between the sliding block and a rear inner end surface of the passage, and a guide pin of which one end is fastened in a front of the insulating housing and the other end is slidably located in the sliding block, the sliding block having a base block, a pushing block extending horizontally from a top of one side of the base block to stretch above the top of the base body for ejecting the electronic card out, a rear of the one side of the base block defining an inserting slot;
• a locking element having an inserting piece inserted into the inserting slot to make the locking element slide along with the sliding block, an elastic portion extending forward from one end of the inserting piece to be slidably disposed in the locking groove, and a locking portion arced upward from a free end of the elastic portion to project beyond the top of the base body so as to elastically resist against a bottom of the electronic card;
• and
• a shielding shell covered on the insulating housing to define an insertion space between the top of the base body and a bottom of the shielding shell for receiving the electronic card therein.
