Card edge connector with a metallic reinforcement piece

A card edge connector comprising:

• an elongated insulative housing having a pair of arm portions at opposite ends thereof, each arm portion having a pair of side walls defining a retaining slot for receiving a module therein, and a resilient arm located between the side walls, the resilient arm comprising a retaining embossment for locking the module, the side wall including a projection;
• a plurality of terminals assembled to said insulative housing;
• and
• a pair of metal latches attached to the arm portions and each having a base and a pair of positioning portions at opposite sides thereof for fixing to the corresponding arm portion and the latch including a stopping plate engaging with said projection for limiting inward movement of the resilient arm when said resilient arm is opened;
• wherein
• each latch has a gripping portion at a top end thereof for urging the corresponding resilient arm.

An electrical connector for use with a memory module, comprising:

• an insulative housing extending along a longitudinal direction, in a front view thereof, with a central slot formed therein for receiving the memory module;
• a pair of resilient arms unitarily extends from two opposite longitudinal ends of the housing in a direction away from the central slot, the arms being respectively equipped with locking heads located around free ends of the corresponding resilient arms and laterally extending toward each other;
• a pair of metallic reinforcement pieces respectively assembled to the opposite longitudinal ends and respectively grasping the corresponding resilient arms;
• the housing including a pair of side walls which define a retaining passage therebetween around each of the longitudinal ends, the retaining passage communicating with the central slot, each of the side walls having a projection portion protruding into the retaining passage so as to not only confine the memory module therein without lateral movements after the memory module is assembled to the housing but also guide insertion of the memory module into the central slot in only a vertical;
• wherein
• the reinforcement piece is outwardly deflected along with the corresponding resilient arm, and vice versa.
