ABSTRACT:
An electronic card connector includes an insulative header retaining conductive contacts for electrically engaging an electronic card received therein. A card ejection mechanism is mounted to the header for selectively ejecting the electronic card from the connector. The ejection mechanism includes a casing retaining a cam plate therein. A push bar is slidably arranged between the cam plate and the casing with an end thereof extending beyond the connector for facilitating manual actuation. A slot is defined in the push bar for receiving a slider therein. The slot drivingly engages with an end of a coupling bar which is coupled to the card driving member. The slider forms a pin movably and guidingly received in a groove defined in the cam plate and forming a closed loop path. A lock plate has a resilient locking section having a free end biased into a notch defined in one side wall of the slot for engaging therewith and preventing the push bar from moving with respect to the cam plate thereby fixing the push bar. A passage is defined between the lock plate and the push bar for movably receiving the end of the coupling bar whereby when an electronic card is inserted into the connector, the coupling bar is moved and the end thereof engages with the locking section of the lock plate to force the free end thereof out of the notch thereby freeing the push bar.
