Printed circuit board retainer assembly
First Claim
1. An assembly for holding printed circuit boards, comprising:
- a rod;
a plurality of members slidably mounted end-to-end on said rod, at least one of said members having a predetermined width and an internal longitudinal channel with a transverse dimension greater than the corresponding outside dimension of said rod to permit movement of said one member along a transverse path relative said rod, said one member and members adjacent said one member each having end portions engageable one another and shaped to force said one member to move in a first direction along said transverse path relative said adjacent members upon forcing of said adjacent members toward said one member;
means for selectively applying force to move said adjacent members towards said one member;
a base structure having first and second side walls defining a recess for receiving said rod and said plurality of members mounted on said rod and for receiving an edge of a printed circuit board adjacent said members, said base structure having an abutment fixedly disposed at one end of said recess, said abutment having an aperture formed therethrough for receiving said rod; and
means, disposed between said abutment and one of said adjacent members, for urging said members away from said abutment upon release of said selectively applied force.

Abstract
An assembly is provided for holding a printed circuit board between spaced surfaces. The assembly comprises a plurality of wedge-shaped members slidably mounted end-to-end on a rod, with at least one of those members being movable in a transverse direction relative to the rod and to its respective adjacent members upon effective shortening of the rod to thereby bring a clamping surface of the transversely movable member into contact with a printed circuit board and to apply a clamping force thereto. The retainer is disposed in a recess of a base structure which includes an abutment formed at one end of the recess. The retainer is activated by rotating the rod thereby urging the slidably mounted members towards one another. Bevelled washers are disposed on the rod between the abutment and one of the end-most members which, when compressed upon tightening of the retainer, provide a force tending to urge the members away from the abutment. When the retainer assembly is loosened the urging force of the bevelled washers tends to move the members along the rod to overcome any surface tension and friction between the clamping surface of the movable member and the circuit board which may tend to preclude quick release of the clamping surface from the board.
