Vehicle control unit structure
First Claim
1. A vehicle control unit structure comprising:
- (a) first and second circuit boards in each of which a conductive layer is adhered on an insulating over a metal substrate, and at least one circuit element is fixed to each said conductive layer;
(b) a connecting substrate electrically connecting said conductive layers on said first and second circuit boards;
(c) a support member supporting said first and second circuit boards and separating the first and second circuit boards from each other with said conductive layers opposing each other, said support member including supporting side plates (i) having stepped portions mating with said first and second circuit boards and (ii) forming segments of a closed case with said first and second circuit boards, the side plates forming three sides of the case, the first and second circuit boards forming the top and bottom of the case, and wherein an opening is formed as a fourth side of the case for receiving a connector member therein; and
(d) a third circuit board, located in said case between said first and second circuit boards, and on which a circuit element is mounted.

Abstract
In a vehicle control unit structure, a pair of first and second circuit boards in each of which conductive layers are adhered on a metal substrate through an insulating layer, and a circuit element is fixed to each of the conductive layers are arranged so that the conductive layers are connected to each other through a connecting substrate and are arranged to oppose each other. A third circuit board is located between the first and second circuit boards. The foregoing vehicle control unit structure is arranged into a closed case-like shape, thus preventing dust contamination and direct access by an operator and achieving a low cost, compact unit. A circuit element is mounted on the third circuit board.
