Abstract:
A PC card connector comprising:a frame in which a PC card is received for electrical connection with an electrical connector, an ejection member pivotally mounted to the frame, a reciprocally-operated eject bar connected to one end of the ejection member for pivotally operating the ejection member to eject a PC card from the card connector, a pressing surface provided at an end of the eject bar which extends beyond the frame; a guide plate assembly operatively connected to the eject bar to reciprocally operate the eject bar including a pressing bar and a guide plate along which the pressing bar moves, a swinging bar connected between the pressing bar and the guide plate, said switching bar having one end pivotally connected to said pressing bar and another end disposed in a single, non-symmetrical cam groove forming a closed curve in the guide plate so that when the pressing bar is moved from an initial position to a card-ejection position in one continuous movement, the swinging bar engages the eject bar thereby moving the eject bar to a card-ejection position; at least one biasing spring provided between the frame and the pressing bar, the at least one biasing spring being offset from the longitudinal axis of the pressing bar, the positioning of the at least one biasing spring allows the continuous movement of the pressing bar from the initial position to the card-eject position to have a long stroke to minimize the force required for the movement.
