Abstract:
To provide accurate insertion of a circuit board into a high density socket in an equipment frame, a lever arrangement is mounted to the circuit board near its upper front edge on a pivot. Rotational force applied to a first lever arm causes a second arm to engage the frame, translating the rotational force to insertion force acting at the pivot. The combination of the acting insertion force and the insertion resisting force of the socket set up a moment couple. The moment couple tends to rotate the circuit board, forcing a reference surface on the board against a mating reference surface on the socket during insertion.
The lever arrangement also provides mechanical advantage for extraction and, by using the resilience of the board, latching. The lever also doubles as a faceplate to protect and beautify the equipment.
