Abstract:
1. A card edge connector for connecting an electrical card to a printed circuit board comprising: an elongated housing having an upper wall and a lower wall defining a mating groove therebetween and extending along a longitudinal direction for an insertion of said electrical card, a plurality of terminal grooves respectively defined in the upper wall and lower wall and in communication with the mating groove; a plurality of contacts, respectively received in said terminal grooves; and a pair of locking devices disposed at opposite longitudinal ends of the mating groove and extending along a rear-to-front direction perpendicular to the longitudinal direction; wherein the mating groove is defined with an upper horizontal surface on the top wall, a lower horizontal surface on a front end of the lower wall, and a lower inclined surface on the lower wall and in the back of the lower horizontal surface under a condition that the card are guided into the mating groove along the lower inclined surface and supported by the upper horizontal surface and lower horizontal surface when the card is rotated downwards to electrically connect with the contacts; wherein the mating groove further is defined with an inner horizontal bottom surface in the back of the lower inclined surface, the inner horizontal bottom surface is construed with two first bottom surfaces and a second bottom surface between the two first bottom surface along the longitudinal direction, the first bottom surfaces are higher than the second bottom surface.
