An electrical connecting arrangement is provided between an electrical edge connector and a printed circuit board in which contact pads provided near the edge of the printed circuit board have a convex profile at least in the direction of insertion of the board into an opening in the edge connector. At full board insertion, each spring contact (3, FIG. 1A) of the connector engages a board contact pad (5) at a location (64) on the pad that lies beyond the center (66) of the pad.
