Abstract:
A card connector comprising:a dielectric housing including a header body, rows of terminal receiving passageways defined through the header body, and a pair of guiding arms extending from opposite ends of the header body for receiving and guiding a card to the dielectric housing, a locking member being integrally formed on an upper surface of the header body;a plurality of conductive terminals being received within the terminal receiving passageways; andan ejection mechanism including a push rod slidably mounted to one of the guiding arms and an extraction plate pivotably connected with the locking member and engaged with the push rod, the extraction plate forming a recessed portion which defines a locking hole in a central portion, the extraction plate being orientable in a non-operating position for permitting the locking member to enter the locking hole and in a normal operating position for being prevented from disengaging the locking member;wherein an annular flange extends from a top of the locking member, the annular flange defining a pair of diametrically opposite notches for a controlled engagement of the locking member with the extraction plate;wherein a periphery of the locking hole includes a pair of diametrically disposed tags respectively corresponding to the notches of the flange of the locking member;wherein the extraction plate has an extraction piece extending from one end thereof and a bent locking hook formed at another end thereof;wherein a locking slot is defined in a distal end of the push rod for engaging with the locking hook of the extraction plate;wherein a pair of receiving protrusions is integrally formed on an outer side of the guiding arm and each receiving protrusion defines a slot for receiving the lever of the push rod;wherein a recess is formed on the upper surface of the dielectric housing thereby adapted to accommodate the recessed portion which is formed in a central portion of the extraction plate.
