Abstract
A double file printed wiring board module arranged to mount printed wiring boards on both sides of a centrally positioned interconnect or side plane while providing for the convection cooling of the printed wiring boards and the interconnection of same with conductors of minimal length. The printed wiring boards are supported by a connector at one side edge and a board guide at an opposite side edge. The interconnect or side plane includes an external termination connector mounted at its rear edge to permit the efficient connection of the circuit module to external terminations.
Claims14
A double file printed wiring board module comprising:
- first and second columns of printed wiring boards, each column including at least one printed wiring board, each board including a component mounting surface, first and second edges, and a plurality of connector tabs adjacent to said first edge to provide access to said board, said board in said first column arranged parallel to said board in said second column without overlap in a direction normal to said component mounting surfaces, said connector tab edge of said board in said first column adjacent to said connector tab edge of said board in said second column;
- a pair of support plates, each support plate positioned adjacent to a different one of said board second edges;
- a plurality of positioners positioning said support plates relative to each other;
- at least one pair of printed wiring board guides, each guide attached to a different one of said support plates and including at least one groove engaged with a corresponding one of said board second edges;
- at least first and second interconnected connectors, each connector engaging said plurality of connector tabs of a different one of said printed wiring boards;
- a side plane positioned relative to said support plates, positioned intermediate to said printed wiring boards, mounting said first connector on a first side thereof and said second connector on a second side thereof not opposite said first connector, said side plane via said connectors cooperating with said support plates via said board guides to support said printed wiring boards;
- an inner plane formed in said side plane intermediate said first and said second side surfaces;
- and
- a plurality of printed wiring conductors formed on said first side surface, on said second surface and on said inner plane, said printed wiring conductors connected in a predetermined manner to said connectors to provide signal paths between said first and second interconnected connectors.
