Abstract: An electronic connector terminal and its method of formation comprising a terminal base material 2 formed from a thin metal plate including and a high cost metal plating layer 17, which covers the terminal base material 2. The terminal base material 2 is preferably formed by punching from the thin plate and includes an outer peripheral edge or lateral part 4 having at least one contact 6, and planer parts 5 defined by front and back surfaces of the punched-out piece. The high cost metal plating layer 17 on the planer parts 5 has a lesser thickness than the thickness of a high cost metal plating layer 17 on the lateral part 4.

Abstract: The present invention provides an electronic connector terminal. The electronic connector terminal according to the present invention comprises a terminal base material 2 which is formed by punching a thin metal plate and an Au plating layer 17 which covers the terminal base material 2. The terminal base material 2 is defined by a cut surface of the thin plate through punching and comprises a lateral part 4 having at least one contact 6, planer parts 5 defined by front and back faces of a punched-out piece. An Au plate layer 17 on the planer parts 5 has the thickness being thinner than the thickness of an Au plate layer 17 on the lateral part 4 having at least one contact 6.

Abstract: The present invention provides a socket 10 which has a housing 20 having a slot 22 for receiving one edge 13 of a daughter board 11 on which terminal portions 12 are mounted, and contacts provided within the slot and pressed against respective terminals of the daughter board 11. From both sides of the housing, latches 31 extend toward the opening direction of the slot. When the daughter board is pressed down against the urging force of the contacts, the latches engage with both side edges 16 of the daughter board. At the position shifted from the center of the edge of the daughter board toward either side edge, a notch 14 is provided, and at the corresponding position of the slot of the housing, a projection for positioning to be fitted in the notch is formed, and at least one side of the projection for positioning, an elastic member 40 for pressing it against the inner side wall of the notch of the daughter board is provided.
