A card edge connector (10) includes an elongated insulative housing (12) having a central slot (16) for receiving a memory card (100) therein, a pair of card ejectors (60) at respective opposite ends of the housing and two rows of contacts (14) received in the housing (12). The housing has a pair of towers (30) at the respective opposite ends thereof, each having a cavity (36) for movably receiving a corresponding ejector therein. Means for preventing over-rotation of the ejectors upon release of the received memory card include an inclined surface (74) in a slit (72) of each ejector and a stopping surface (48) of a pillar (44) in a corresponding cavity, and a pair of blocks (20) adjacent to a corresponding tower (30). The inclined surfaces of the ejectors abut against the corresponding stopping surfaces of the pillars and the ejectors abut against the blocks, thereby preventing overrotation of the respective ejectors.

1. An electrical connector for safely release an electronic card engaged therein comprising:an elongated insulative housing defining a central slot in a mating surface thereof, the slot being adapted to receive the electronic card therein; a plurality of contacts received in the housing, for electrical and mechanical engagement with the electronic card in the housing; at least one tower formed at one end of the housing, each tower having a cavity and a pillar in the cavity, the pillar having a stopping surface at a top end thereof; and at least one card ejector movably received in the cavity of the at least one tower, the at least one card ejector having an operation lever and a card eject portion at a bottom end of the operation lever, the at least one card ejector defining a slit at the bottom end thereof movably receiving the pillar of the at least one tower therein, the slit having a top periphery adapted to abut against the stopping surface of the pillar to limit rotation of the at least one card ejector upon the at least one card ejector completely releasing the electronic card from the connector; wherein the top periphery of the slit has an inclined surface relative to a bottom surface of the ejector for abutting against the stopping surface of the pillar to prevent the at least one card ejector from outward over-rotation; wherein the top periphery of the slit further has a horizontal surface for allowance of the inward rotation of the at least one card ejector; wherein the at least one tower has a bottom wall and the pillar upwardly extends from the bottom wall into the corresponding cavity; wherein the stopping surface of the pillar is generally parallel to the mating surface of the housing; wherein the housing further includes a plurality of engaging blocks, each adjacent to an inward edge of each of two side walls of each tower, each engaging block having a horizontal engaging surface for abutting against the eject portion of the at least one card ejector; wherein each engaging block further has a vertical surface perpendicular to the horizontal engaging surface, the vertical surface being adapted to allow rotation of the at least one card ejector.
