ABSTRACT:
A connector adapted to be attached to a mother printed circuit board and to removably receive a daughter printed circuit board of the edge card type and adapted to mechanically and electrically couple the mother and daughter printed circuit boards, the connector comprising an electrically insulating housing; and a plurality of electrically conductive contacts extending through the housing in rows of spaced pairs for removably receiving an edge of a daughter printed circuit board in a central plane between the rows, each contact including a lower section formed as a solder tail positionable to depend from the housing for coupling with the mother printed circuit board; an intermediate section extending upwardly from the solder tail and inwardly toward the central plane for supporting a received daughter printed circuit board; and an upper section extending upwardly and outwardly to define, at the bight of the upper and intermediate sections, a contact area of compound radii configuration on the radially exterior face of the bight bowed outwardly with respect to the radially interior face of the bight, with the contact area of each pair of contacts facing toward each other for contacting the traces on the edge of a received daughter printed circuit board. Also disclosed is the method of fabricating such connectors by coining and bending.
