Description

  The present invention relates to an electronic card connector, and more particularly, to an electronic card connector that can complete the withdrawal operation of the electronic card by propelling the electronic card inserted therein.

  Since the volume of an electronic card is small and the storage capacity is large, it is widely applied to various electronic products, for example, portable electronic products such as a mobile phone, a digital camera, or a personal digital assist device. A circuit board and an electronic card connector are provided in the electronic product. The electronic card connector is fixed to the circuit board, and the electronic card is inserted into the electronic product and electrically contacted with the conductive terminal. And become electrically connected. At the same time, the electronic card connector provides a card withdrawal function and allows the electronic card inserted therein to be taken out smoothly. Since electronic card insertion and withdrawal operations are frequently performed, the electronic card connector must have sufficient durability to maintain smoothness during insertion and withdrawal of the electronic card. Ensure electrical contact with the conductive terminals of the card connector and avoid situations where failure to exit the card occurs.

  As shown in FIG. 1, a conventional electronic card connector has an electronic card (not shown) inserted therein, and includes an insulating body 6, a conductive terminal 7, a card withdrawal mechanism 8, and a cover case 9.
