ABSTRACT:
A chassis for electronic circuit modules is disclosed in which a support frame is fabricated from two flat side panels spaced apart by four rods. The rods may be of variable length to accomodate various chassis widths. Each electronic circuit module is comprised of the printed circuit board or boards on which the circuit components, including switches, indicator lights and connectors are mounted, a front panel with cutouts for the lights or switches and a back panel with cutouts for the connectors. The front panel and the back panel are mounted perpendicularly on the ends of the printed circuit boards with the lights and connectors protruding through at appropriate locations. Each of the printed circuit boards has four slots which engage the four rods so that, when the modules are placed in the frame and the rods are in place, the modules are rigidly locked together to form a unit. The package is completed by removable top and bottom panels which are held by clips onto the rods. Power and ground and data signals are conveyed between the modules by means of an internal cable which connects the modules in parallel so that only connections with external circuitry need be made through the back panel connectors.
