Abstract: In an electrical connector provided with side openings mounted on protruding edge contacts of a printed circuit board, providing an opening through the main body of the board on each side of the protruding edge contacts. A flat-bottomed upper portion of an anchor rests on top of the board, if placed horizontally, and a pin extends downwardly from one end of the anchor through an opening in the board. A block extends downwardly from the opposite end of the anchor approximately perpendicular to the pin and distanced therefrom so that the inner face of the block is flush with the edge of the board. The outer end face of the block conforms with the outer end of the upper portion of the anchor. A cylindrical horizontal opening extends between the outer and inner faces of the block. When the connector is pushed onto the edge contacts, the connector openings align with the anchor openings, and a screw may be inserted through each aligned pair of openings to secure the connector in place.
