Electrical component and bus element assembly
First Claim
1. A circuit module comprisinga framework including first and second end bus elements having flanges on both sides for connecting printed circuit boards thereto, a central bus element having flanges on both sides thereof for connecting printed circuit boards thereto, a pair of connecting elements connecting one end bus element in spaced relation to each side of said central bus element, and means for electrically isolating the end bus elements from the central bus element;
- at least one circuit board extending on each side between the end bus elements; and
means structurally and electrically connecting each circuit board to the flanges of each end bus element and the central bus element,whereby electrical potential levels on each end bus element and the central bus element are applied to the circuit board through the connecting means.

Abstract
A circuit module is disclosed wherein a supporting framework for the module also serves as a voltage and ground bus structure for providing appropriate connections for voltage distribution to circuit boards which are assembled on the framework to form the walls of the module. This facilitates the use of circuit board input-outupt connections on all edges. The completed structure forms a hollow configuration which acts as a plenum chamber to facilitate the cooling of components mounted on the circuit boards. Two different types of supporting frameworks are disclosed. Also disclosed are arrangements for disposing assemblies of circuit modules within cabinets in such a manner as to facilitate ready access thereto.
