An electrical connector (10) has a body, a center conductor (55), and an insulator (75). The body has a receptacle end (30), a board end (25) having a rear plane (85) and a plurality of fastener holes for a plurality of fasteners (50), a void extending from the receptacle end to the board end, and a grounding feature (70) substantially surrounding the void at the board end, the grounding feature extending beyond the rear plane and being approximately in the shape of a “V” having a base which points away from the rear plane. The center conductor is in the void and extends from the receptacle end to beyond the rear plane of the board end. The insulator is in the void and substantially surrounds the center conductor in the void.
