Patent ID: 6992249

Claim:
A method for clamping a plurality of circuit cards within a receptacle, the method comprising: attaching at least one cam rotatably to the receptacle; rotating selectively the at least one cam to engage a frame within the receptacle, the frame partitioned into first and second sub-frames by a first partition, each of the first and second sub-frames partitioned into an array of slots by a plurality of second partitions, each slot containing one of the circuit cards; exerting a force on the first sub-frame using the at least one cam; sliding the first sub-frame using the force exerted on the first sub-frame so that circuit cards of the first sub-frame contact the first partition; exerting a force on the first partition using the circuit cards of the first sub-frame; sliding the first partition into contact with the circuit cards of the second sub-frame using the force exerted on the first partition by the circuit cards of the first sub-frame; and securing the circuit cards contained in the slots of the first sub-frame between the first sub-frame and the first partition and the circuit cards contained in the slots of the second sub-frame between the first partition and the second sub-frame by maintaining the force on the first sub-frame using the at least one cam.
