Abstract

An electronic card connector is provided with a plugging surface and a slot extending to the inside from the plugging surface and comprises: an insulated body, a conductive terminal arranged on the insulated body, a card withdrawing mechanism and a fastening part convexly extending into the slot and used for the collision against an electronic card. The card withdrawing mechanism comprises a sliding block moving along the socket direction of the electronic card, an elastic part driving the sliding block to move and a stopping part which can sequentially fix the sliding block at a first position as well as a second position closer to the plugging surface than the first position. The sliding block has a contacting part that convexly extends to the slot and is contacted with the front end of the electronic card. The electronic card connector is provided with a limit part at the first position. The limit part is used for enhancing the pressure from the fastening part against the electronic card. By virtue of such design, the electronic card can be prevented from springing out of the electronic card connector due to over strong elasticity of the elastic part in the process of withdrawing cards.
