Abstract:
A mechanism for ejecting an electronic card inserted into a card connector, comprising:a memory alloy wire having a fixedly anchored first end, and a movable second end;a card ejecting plate reciprocally mounted on the connector for ejecting a card inserted into the connector;a lever pivotably mounted to the connector, having a first end drivably connected with the card ejecting plate and a second end;a guide fixed to the connector;a force transmitting member drivably connected with the second end of the lever;a slider reciprocally mounted on the guide and fixedly connected with the second end of the wire wherein when an electrical current is applied to the wire causing the wire to retract, the slider moves from a first position to a second position;a push rod pivotably mounted to the slider; anda first resilient member exerting a biasing force on the push rod toward the force transmitting member;wherein when the slider is at the first position, the push rod engages with the force transmitting member, during movement of the slider from the first to the second position, the push rod pushes the force transmitting member causing the lever to pivot, thereby causing the card ejecting plate to move to eject an inserted card, and when the slider reaches the second position, the push rod is disengaged from the force transmitting member.
