Abstract
A memory card includes a metal shielding enclosing an insulative housing in which contacts are received for suppressing noise. A card connector is adapted to receive the memory card therein and includes an ejector mechanism having a push bar and a lever plate for ejecting the memory card. The lever plate is operative to pivot about a protrusion formed on a metal frame which also shields noise into/from the card connector.
Claims19
A card connector comprising housing/guiding means which includes a contact reception housing defining a plurality of passageways for receiving contacts therein and two guiding arms extending from distal ends of the housing each defining an inner channel confronting each other for guiding an external memory card toward the housing, an identification protrusion projecting from one of the inner channels thereby forming an asymmetric structure between the inner channels for ensuring correct orientation of the external memory card during insertion.
A memory card comprising:
- an insulative housing having a top wall, a bottom wall, and two side walls connected therebetween, thereby defining a reception space between the walls;
- a printed circuit board received in the reception space of the insulative housing;
- a contact reception housing positioned in the reception space of the insulative housing and defining a plurality of passageways for receiving corresponding number of contacts therein;
- and
- an identification member extending from at least one of the side walls and having an asymmetric cross-section for ensuring correct orientation of the memory card during insertion into an external card connector.
A memory card/card connector assembly comprising:
- a memory card comprising an insulative housing having a top wall, a bottom wall, and two side walls connected therebetween, thereby defining a reception space between the walls, a printed circuit board received in the reception space of the insulative housing, a contact reception housing positioned in the reception space of the insulative housing and defining a plurality of passageways for receiving a corresponding number of first contacts therein, and an identification member extending from at least one of the side walls and having an asymmetric cross-section;
- and
- a card connector comprising housing/guiding means which includes a contact reception housing defining a plurality of passageways for receiving a corresponding number of second contacts therein and two guiding arms extending from distal ends of the housing each defining an inner channel confronting each other for guiding the memory card toward the housing;
- whereby the identification member of the memory card only fits into the inner channels of the card connector with a predetermined orientation thereby ensuring correct orientation of the memory card during insertion into the card connector.
A card connector comprising housing/guiding means which includes a contact reception housing defining a plurality of passageways for receiving contacts therein and two guiding arms extending from distal ends of the housing each defining an inner channel confronting each other for guiding an external memory card toward the housing, a metal frame attached to the housing, a lever plate having a base movably positioned between the housing and the metal frame, at least one ejection tab extending perpendicularly from the base of the lever plate for ejecting an inserted memory card, and said lever plate being pivotable about a protrusion of the frame by which the housing and the frame is aligned and oriented.
