  • Patent number: 7008245
    Abstract: A card connector has an insulative frame, a plurality of conductive terminals received in the insulative frame, an eject device assembled on the insulative frame and a shell covering the insulative frame. The eject device includes a driving rod, a driven shaft, a driven sleeve, a slider and a resilient element. The driving rod axially defines a 90 degree first continuous chute, and the driven shaft axially defines a 90 degree second continuous chute for meshing with the first continuous chute. The driven sleeve is fixed on the insulative frame and telescopically meshes with the driven shaft. The slider is cantileveredly mounted on the driving rod. During insertion of the card, the driving rod drives the driven shaft to rotate. A stop block of the driven sleeve disengages from an abutting portion of the slider, and thereafter engages with a wedging hole of the card. Thus, the card in final position is protected against exterior reverse shock.
