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.

Abstract: Surface mount connectors having staked alignment pins. The bodies of the connectors are formed without alignment pins, and alignment pins are thereafter staked into the bottom surface of the connector body in order to positively locate the connector when mounting to a printed circuit board. Because the alignment pins are not integrally formed with the connector bodies, the connectors may be inventoried in only long strips of, for example, 50 positions. After a customer order is received, the long strips may be cut to the desired number of positions. The alignment pins are thereafter staked into the connector body in order to form a completed connector. The present invention therefore obviates the need to inventory connectors with alignment pins in each of the potentially desired sizes.
