Abstract:
A card connector for electrically connecting a card including a mating connector having a plurality of mating contacts to a printed circuit board, which comprises:a connector portion comprising a base insulator having a front surface, an upper surface, a bottom surface and a rear surface, and a plurality of contacts fixed to said base insulator, each of said plurality of contacts comprising a contact portion protruding from said front surface to be brought into contact with said corresponding one of said mating contacts and a terminal portion protruding from one of said bottom surface and said rear surface for making an electrical connection with said printed circuit board:a frame portion mounted onto said connector portion and having an upper wall, a lower wall, and opposite side walls to form a rectangular tube for receiving said card therein, said upper wall having a rear extension portion extending rearward to overlie said upper surface of said base insulator when said frame portion is assembled onto said connector portion; andan ejector mechanism assembled on said frame portion for ejecting said card from an electrical connection between said connector portion and said mating connector, said ejector mechanism comprising an ejector rod slidably mounted and guided onto one of said side walls of said frame portion and a lever pivotally mounted by a pivot onto said rear extension portion of said upper wall, said lever having an end as a card engaging end for engaging with said card received in said frame portion and an opposite end connected to said ejector rod, said lever being pivotally moved in response to movement of said ejector rod to push said card frontward, said card having a side surface in which a key groove is formed,wherein one of said opposite side walls of said frame portion has an inner key corresponding to said key groove so as to prevent said card from being inserted into said frame portion in an erroneous orientation.
