PROBLEM TO BE SOLVED: To provide a connecting device for a power module for connecting the power module with a circuit board so as to supply power to the circuit board, in which an electrical circuit is formed from the power module. SOLUTION: In a connecting device for a power module in which the power module 01 is joined with a circuit board 06 by interposing a bush 7, a disk- shaped fixing ring 16 is provided, which is provided with an inner diameter slightly smaller than an outer diameter of a small diameter cylinder 011 of the bush 7. The ring 16 is fitted to the upper end of the small diameter cylinder 011 protruded upwards penetrating an engaging hole 09 disposed on the circuit board 06, and which is provided for joining the circuit board 06 and the power module 01 with each other through the bush 7. Thereby, there is no need for a soldering treatment applied on all outer peripheral surfaces of the bush 7 for joining the bush 7 with the circuit board 06. |
