Abstract
Abstract A plurality of like modules having an open sided C-frame construction are provided with slot-forming guides for receiving a plurality of circuit boards which are inserted from the open side. The circuit boards, when fully received in the guide slot, are engageable with electrical connectorings on the main body section of the C-frame. A plenum chamber is formed on the bottommost surface of the plurality of C-frame modules, and vent slots are provided through the modules at the upper and lower limbs of the C-frame, thereby permitting air to be ducted through the plenum chamber and convected up through the vent slots, thereby dissipating heat from the circuit boards. Means is provided for connecting the plurality of modules in a predetermined fashion to one another, to form a rigid assembly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A modular circuit board guide assembly, comprising: (a) a plurality of identical molded plastic modules, each having a one-piece generally C-frame construction including respective upper and lower limbs extending from a main body section; (b) guide means for a single circuit board formed by and between said upper and lower limbs of cooperating side-by-side modules, said guide means comprising a slot having two sides, one side formed by one module and the other side formed by the other module; (c) a circuit board connector mounted to said main body section of at least one of said modules; (d) fastener means for securing said plurality of modules together in seriatem; (e) registering means for locating said plurality of modules in a predetermined orientation with respect to one another; (f) a plenum chamber integrally formed on the respective lower limbs of said modules and enclosed with suitable cover plates; and (g) a vent passage formed across each of said upper and lower limbs, transversely through said slot, said lower limb vent passage in vent communication with said plenum chamber.
