Patent ID: 7189093

Claim:
A socket connector for electrically connecting an integrated circuit package to a printed circuit board comprising: an insulative housing holding a plurality of conductive terminals thereon and defining a bottom wall round the terminals; a stiffener body surrounding the housing; a load plate pivotably assembled with one end of the stiffener; a load lever pivotably assembled with the other end of the stiffener; wherein the housing defines a plurality of semi-cylindrical protrusions extending from the bottom wall toward the PCB, each of the protrusions defining a bottom surface substantially parallel to the PCB and a side surface substantially perpendicular to the bottom surface, and the stiffener defines a plurality of semi-circled slits corresponding to the protrusions, and the housing is assembled with the stiffener body by virtue of cooperation of the protrusions and the slits so that a distance from the bottom surface to the PCB is shorter than a distance from the bottom wall to the PCB.
