ABSTRACT:
A land grid array connector for electrically connecting a CPU package (60) to a printed circuit board includes a housing (10) received a number of contacts (12) therein, a stiffener (20) enclosingly attached to the housing, a load plate (40) and a lever (30) pivotally mounted to opposite sides of the housing respectively. The housing has a number of sidewalls. Two wings (45) extend downwardly from opposite side edges of the load plate and toward the housing. A stopping member is formed on the wings of the load plate and two opposite sidewalls of the housing corresponding the wings, for resisting horizontal moving of the load plate and the CPU chip. The stopping member comprises a plurality of protrusions and holding sections engaging the protrusions. The protrusions each engagingly retained in a corresponding holding section during the connector being in closed position. This can resist horizontal moving of the load plate and the CPU chip. Further, this thereby protects the housing from being collided and scraped by motion of the CPU chip. As a result, reliable electrical connection between the CPU chip and the contacts of the connector is obtained.
