Claim:
A card edge connector adapted for rotatablely receiving a larger daughter board to a mother board from a first position in which the daughter board is oblique to the mother board to a second position in which the daughter board is parallel to the mother board, and comprising: an insulating housing defining an elongated slot therein; a plurality of contacts received in the housing; a pair of stopping arms setting to the ends of the housing respectively, and each defining a first bottom face thereof; a pair of supporting walls each integrating with the stopping arm and being long enough to reach to the stopping arm, and each supporting wall extending downwards from the stopping arm and providing a second bottom face disposed lower than the first bottom face of the stopping arm; and wherein the stopping arms and the supporting walls are immovable relative to the housing during the rotation of the daughter board between the first position and second position; wherein the stopping arm forms a slanting surface thereof to protect the stopping arm from being scraped by the daughter board; wherein a front portion of the supporting wall is cut-out partially to define a receiving room; and wherein an outer surface of the stopping arm projects outward beyond an outer face of the supporting wall to define a receiving room below the stopping arm.
