Abstract
A mechanical insertion/ejection lever device is provided for use in mounting a printed circuit board (PCB) into an electrical receptacle secured to a housing. Two lever members are pivotally mounted at or near the rear edge of a PCB, adjacent the corners. As the PCB is manually inserted into the housing unit, the lever members engage part of the housing. Rotation of the lever members causes a proportional linear motion of the PCB into engagement of the receptacle, overcoming frictional resistance of the electrical connectors. The lever members are rotatable through an arc of motion which corresponds to moving the PCB a linear distance sufficient to compensate for all accumulated manufacturing tolerances while fully seating the PCB within the receptacle. The lever members adjustably lock to retain the PCB in a fully seated position. The lever members also eject the PCB from the receptacle upon rotation in an opposite direction.
