ABSTRACT:
The invention is directed to a socket (2) having an improved contact area (24) which allows a pin (4) to be inserted therein at an improper orientation relative to the axis of the socket (2). Coined edges (28) of beams (16, 18) prevent the corners (32) of the pin (4) from contacting the beam (16, 18), thereby ensuring that electrical engagement is provided between the embossments (24) provided on the beam (16, 18) and the flat, highly finished surfaces (26) of the pin (4). The embossments (24) are configured to be easily reproducible and durable to last over many cycles. A lead in surface (44) provided on the embossments (24) prevents excessive wear on the embossments (24), as well as providing for easy insertion of the pin (4) into the socket (2).
