  • Patent number: 8454380
    Abstract: A card edge connector includes an elongated housing having an upper wall and a lower wall defining a mating cavity therebetween and extending along a longitudinal direction. A plurality of terminal grooves are respectively defined in the upper wall and lower wall and in communication with the mating cavity. A plurality of contacts are respectively received in said terminal grooves. A pair of locking devices are disposed at opposite ends of the mating cavity and extend along a rear-to-front direction perpendicular to the longitudinal direction. A recess facing the upper wall is defined in the lower wall and extends along the longitudinal direction under condition that two longitudinal ends of the recess are closer to the upper wall than a middle portion of the recess.
