  • Patent number: 8822855
    Abstract: A card connector includes an insulating housing having two side walls of which an inside defines an inserting fillister, electrical terminals including a switch terminal which has a first contact arm and a first contact tail protruding from a free end of the first contact arm, and an upper shielding shell covered on the insulating housing and having two side plates of which one is die-cut to form a connecting slice inserted in the inserting fillister. A bottom of the connecting slice is bent inward to form a ground slice. The card connector utilizes the cooperation of a controlling switch of an electronic card and the first contact arm to control connection and disconnection between the first contact tail and the ground slice so as to further control a write procedure of the electronic card, wherein the controlling switch is movable between a closed position and an open position.

  • Patent number: 8708742
    Abstract: A card connector includes an insulating housing having a pair of side walls of which one protrudes outward to form two stop blocks spaced along a front-to-rear direction, a plurality of electrical terminals disposed in the insulating housing, an upper shielding shell covered downward on the insulating housing, and a lower shielding shell covered upward under the insulating housing. The upper shielding shell has a top plate and a pair of side plates of which one is die-cut to form a positioning slice restricted between the stop blocks of the corresponding side wall. A front of each side plate is punched outward to form a vertical arched restricting portion. The lower shielding shell has a bottom plate and a pair of lateral plates of which a front of each top edge is concaved downward to form a restricting gap buckling the corresponding restricting portion therein.

  • Publication number: 20130237079
    Abstract: A card connector includes an insulating housing defining a receiving chamber and an inserting chamber connected with the receiving chamber, electrical terminals assembled in the insulating housing, and a shielding shell enclosing the insulating housing. Two receiving fillisters are opened in two inner sides of two side walls forming at two opposite sides of the receiving chamber. Two restraining members each has a base strip disposed in the receiving fillister, and an elastic arm inclined inward into the receiving chamber. The elastic arms are pressed into the receiving fillisters when a SIM card is inserted in the receiving chamber. In the process of inserting a micro SIM card into the card connector, the elastic arms resist against two opposite side edges of the micro SIM card to guide a rear of the micro SIM card to be smoothly inserted into the inserting chamber.

  • Patent number: 8500471
    Abstract: A card connector includes an insulating housing defining a receiving chamber, and electrical terminals disposed in the insulating housing. A fool-proofing board has top edges of a front end thereof designed with slopes. Two lifting terminals are disposed in two sides of the receiving chamber with elastic portions thereof projecting upward in the receiving chamber to prop the fool-proofing board over the receiving chamber. Wherein the fool-proofing board can be pressed downward into the receiving chamber by a common SIM card under the guiding of the slopes, or move rearward under the drive of a micro SIM card of which a rear is inserted in the front end of the fool-proofing board. An ejection device is assembled in the insulating housing for ejecting the cards out of the card connector. A shielding shell is covered on the insulating housing.
