Abstract:

A first aspect of the invention is an electrical connector that includes a housing formed to include first and second opposing ends and an elongated slot between the ends. The slot receives a connective edge of a printed circuit card. Closely spaced contacts located in the slot engage conductive pads on the printed circuit card. A first alignment member is formed integrally at the first end of the housing, to engage a non-polarized keyway during insertion of the printed circuit card into the elongated slot, aligning the printed circuit card relative to the contacts. A second aspect of the invention is the keying of the printed circuit card along a connective edge. The connective edge includes two connective regions which define a polarized keyway between the two connective regions. A third, non-connective, region located at one end of the connective regions defines a non-polarized keyway between the connective regions and the non-connective region. The polarized keyway is the dimensional datum point for fabrication of the printed circuit card and the non-polarized keyway is located precisely with reference to the polarized keyway.
