Abstract
An expandable clamp of the type that is used within a channel to compress a planar member within that channel against a wall of that channel. The clamp has an expandable bladder of an elongated cylindrical shape and a valve for introducing a gas or a liquid into the bladder for expanding it. Alternatively, the clamp may be manufactured with a closed bladder that is partially filled with a fluid. This closed bladder may be expanded by increasing the pressure on the fluid such as by compressing the fluid with a piston. The clamp is particularly suited for use in Standard Electronic Modules for providing more uniform contact between the frame of the electronic module and the card chassis of the instrumentation.
