A card connector includes an insulating housing, a plurality of terminals, an ejection mechanism, a locking element and a shielding shell. The terminals are received in the insulating housing. The ejection mechanism is assembled in the insulating housing, and includes a sliding block, an elastic element and a guide pin. The sliding block includes a base block. A rear of the one side of the base block defines an inserting slot. The locking element has 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 insulating housing, and a locking portion arced upward from a free end of the elastic portion to project beyond the top of the insulating housing. The shielding shell is covered on the insulating housing.

1. 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; anda 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. 2. The card connector as claimed in claim 1, wherein the sliding block further has a locating block extending horizontally from a front of the other side of the base block and projected into the passage, a second pillar is protruded rearward from a rear surface of the locating block and located in the passage, a first pillar is protruded forward from the rear inner end surface of the passage, the elastic element is received in the passage with one end thereof being worn around the first pillar and against the rear inner end surface of the passage, and the other end thereof being worn around the second pillar and against the rear surface of the locating block. 3. The card connector as claimed in claim 1, wherein a rear end of the shielding shell extends downward to form a rear plate blocking a rear of the insertion space. 4. The card connector as claimed in claim 1, further comprising a first switch terminal and a second switch terminal transversely disposed in a rear end of the base body, the first switch terminal having a lying U-shaped first fixing portion of which a lower free end is inclined downward and then extends horizontally to form a first soldering foot projecting under the base body, and an upper free end is designed with a touching portion of a hollow hemispherical shape projecting beyond the top of the base body with the mouth thereof facing the soldering foot, a free end of the touching portion further extending horizontally to form a first connecting portion, the second switch terminal having a second fixing portion of which one end is inclined downward and then extends horizontally to form a second soldering foot projecting under the base body, the other end of the second fixing portion being curved upward and then extending horizontally to form a second connecting portion of which a free end is located apart under the first connecting portion, the free end of the second connecting portion electrically connects with the first connecting portion when the touching portion is pressed downward by the electronic card. 5. The card connector as claimed in claim 1, wherein the rear of the one side of the base block of the sliding block extends horizontally to form a supporting board located under the inserting slot and projected into the locking groove to prop up the one end of the inserting piece and a rear of the elastic portion of the locking element. 6. The card connector as claimed in claim 5, wherein the base block of the sliding block defines a fastening hole vertically penetrating therethrough and communicating with the inserting slot, the inserting piece of the locking element defines an inserting hole aligned with the fastening hole, the locking element is fastened to the base block by means of using a fastening element to pass through the inserting hole and the fastening hole.
