Abstract
A printed circuit board retainer for use in a rack or the like is provided comprising a housing member having an elongated slot adapted to receive a printed circuit board. A series of cam ramps are provided within the interior of the housing member. Mounted within the housing member is an elongated cam member adapted to move relative to the cam ramp of the housing member. The cam member has a plurality of follower ramps that are designed to bear against the cam ramps of the housing member. A lever member is pivotally mounted at one end of the housing member for actuating the cam member. The cam member as a result of the coaction of the follower and cam ramps is capable of exerting a retaining force in a direction traverse to the face of the printed circuit board.
