Circuit structure that connects an electronic part to a conducting path

Abstract

There is provided a circuit structure in which a control circuit is formed on the upper surface of an insulating plate 14 by control busbars 15, and a power circuit is formed on the lower surface of the insulating plate 14 by power busbars 18. By this configuration, the circuit structure can be made small in size as compared with the case where the control circuit and the power circuit are formed on separate circuit boards. Also, the insulating plate 14 is formed with an opening 23, and a power busbar 18 is positioned over the opening 23. In the opening 23, a terminal 25B of a relay 16 is positioned, and is connected to the power busbar 18. Thereby, the connecting work process can be simplified as compared with the case where the power circuit and the terminal 25B of the relay 16 are connected to each other, for example, by a jumper wire.
