Pin receptacle intended for mounting in a circuit board comprises a hollow metallic cylindrical member having first and second ends. A contact lance is struck or sheared from the cylindrical member and has a fixed end that is adjacent to the second end of the cylindrical member. The contact lance extends inwardly from its fixed end to the interior of the receptacle and has a pin contacting portion intermediate its ends. An end portion of the lance is reversely curved and extends through the opening formed by the shearing operation to the exterior of the cylindrical member. A circuit board conductor contacting portion is on the end of the lance. Stop lances are also struck from the cylindrical member adjacent to the second end and extend obliquely from its surface. Anti-overstress lances are also struck from the cylindrical member and extend obliquely towards the second end of the cylindrical member. When the receptacle is mounted in a hole in a circuit board, the surfaces of the board are contacted by the stop lances and the anti-overstress lances. The contact lance is positioned above the one surface of the circuit board with the contact portion or zone in engagement with end against the circuit board conductor. |
