<p>The boardlock for holding a socket to a circuit board comprises an integral body including a main beam, a socket retention section adapted to self-retain to the socket, and a circuit board retention section engageable in a hole in the circuit board. The circuit board retention section is substantially flat and, together with at least the main beam, defines a plane. The circuit board retention section includes a pair of spaced apart legs extending in the plane from the main beam to a common remote end defined by a tie bar. The legs are dimensioned to extend beyond an exit of the hole at a far side of the circuit board. Portions of the legs are divergently angled as they extend to a widest dimension of the circuit board retention section. The widest dimension is chosen to be wider than a widest dimension of the hole exit in the circuit board, and to be spaced from the main beam by a distance greater than a thickness of the circuit board at a periphery of the hole exit. Further portions of the legs are convergently angled as they extend from the widest dimension to the remote end. The structural arrangement of the circuit board retention section makes it compliant substantially exclusively in the direction of the plane, and the divergently angled leg portions are spring biased against the periphery of the hole exit through a range of board thickness and hole diameter variations.</p> |
