Card edge connector with improved engagement of ground contacts and ground plate

A card edge connector comprising:

• an insulating housing comprising opposite long walls and defining a card slot between the long walls;
• at least one row of contacts retained in the long wall and the row of contacts comprising ground contacts and signal contacts, the ground contacts comprising retaining sections retained in the housing, elastic sections extending upward from the retaining sections with mating portions exposed to the card slot, and leg sections extending downward from the retaining sections;
• at least one ground plate retained in the long wall;
• wherein the elastic section includes an engaging portion slanting outward from the retaining section, and the engaging portions press against the ground plate and provide pivot points of the elastic sections rotating outward when a module is inserted in the card slot.

A card edge connector for use with a memory module, comprising:

• an elongated insulative housing including a pair of side walls extending along a longitudinal direction, and a pair of end walls linked between two opposite ends of said pair of side walls and extending in a transverse direction perpendicular to the longitudinal direction;
• a card receiving slot formed among the pair of side walls and the pair of end walls for receiving the memory module;
• two rows of passageways formed within the pair of side walls and communicating with the card receiving slot in the transverse direction;
• two rows of contacts retained in the corresponding passageways, respectively, said contacts including grounding contacts and differential pair signal contacts alternately arranged with each other in the longitudinal direction and having similar configurations with each other, each contact including an immovable retaining section and a deflectable contacting section extending into the card receiving slot with a curved engaging portion therebetween;
• a pair of grounding members retained in the housing, each of said grounding members forming a planar immoveable configuration in the housing and including a long bar extending continuously along and having a similar length with the corresponding side wall;
• and
• the engaging portion of each grounding contact electrically and mechanically connect to the grounding member while the engaging portion of each signal contact abuts against the housing.
