Abstract: A coaxial connector 10 includes a conector body (21) and a plurality of grounding pin contacts (25, 25) extending from the connector body (21) to be extended into and through a plurality of apertures (32, 32) in a printed circuit board (12) to electrically and mechanically connect the connector (10) to the board (12). The grounding pin contacts (25, 25) have a length greater than the thickness of the board (12) and include first compliant pin contact portions adapted to be positioned within the apertures (32, 32) to frictionally engage the sidewalls of the apertures (32, 32) to frictionally retain the connector (10) to the board (12) and to electrically connect the connector (10) to the board (12), and second compliant pin contact portions (51, 51) which extend out of the apertures (32, 32) beyond the opposite side of the board (12) and which, upon, passing through the apertures (32, 32) expand to a diameter greater than that of the apertures (32, 32) to mechanically lock the connector to the board.
