A lock pin (4,5) includes an arm to be inserted into a mounting aperture of a mounting plate and fixed to a metal portion around the mounting aperture by soldering, and an anchoring projection (3d) formed at an end of said arm. The arm is provided with a melted solder induction protrusion (7,8a,8b) for guiding melted solder to distribute it extensively on the metal portion. An electrical connector includes a connector main body (1), a front shell (2) surrounding the connector main body, and the lock pin to be secured to the connector main body and having an anchoring projection (3d), an arm (3c) electrically connected to the front shell and the melted solder induction protrusion (7,8a,8b). When a melted solder is positioned between the surface of the mounting plate and the induction protrusion, the induction protrusion is "wetted" with the melted solder. Therefore, the melted solder flows with the aid of its surface tension along surfaces of the induction protrusion to arrive at the arm of the lock pin and further flows along the arm of the lock pin to the back surface of the mounting plate with ease, whereby the mounting plate and the lock pin are fixed with great certainty. <IMAGE> |
