Abstract
Abstract An electrical connector includes an elongated dielectric housing having an elongated slot disposed generally along a longitudinal axis of the housing for receiving, edgewise, a printed circuit board. A plurality of terminals are inserted through a bottom terminating face of the housing into a plurality of passages along at least one side of the slot. Each terminal includes a retention portion press-fit in a retention section of a respective passage. The retention section includes inner side walls and an outer side wall which guides, locates and supports the retention portion and, thereby, the terminal within its respective passage. The retention area of the outer side wall is substantially greater than the retention area of the inner side walls.
