Abstract: A guide rib is protrusively formed on a bottom face of a connector housing to position the connector housing to a printed circuit board by piercing the printed circuit board. A groove portion is hollowly formed around a base portion of the guide rib to disperse the screw tightening stress and prevent the guide rib from cracking as the connector is fixed to the printed circuit board. It disperses stress caused by tightening a screw for connecting the connector housing with the printed circuit board, and therefore prevents cracking on the base portion of the guide rib resulting from concentration of the stress. Since the groove portion is hollowed, the connector housing adheres securely to the printed circuit board, therefore resulting in a stable mounting.
