題があつた。(Problem to be solved by the invention) However, such means lacks waterproofness because the screws are passed through from the outside of the casing, and if there is a slope in the casing recess where the module is housed, the module will tilt and the casing will be damaged. There was a problem in that the positions of the through holes in the body and the guide holes in the flange did not match, making stable installation difficult.

り詳細に説明する。(Means for Solving the Problem) In order to solve these drawbacks, the present invention has been developed by sandwiching the flange of the power module between the fixed block and the casing, and tightening it with a tightening screw, so that the flange of the power module can be tightened with the slope of the casing. It is fixed by the force acting between the slopes of the fixing block, and examples thereof will be explained in detail below with reference to the drawings.

付側の壁面である。(Example) Figure 1 is a perspective view of the component configuration before parts are installed, where 1 is the power module, 2 is the flange of the power module, 3 is the guide hole of the power module flange, and 4 is the fixing block. , 5 is a slope of the fixed block 4, 6 is a guide pin of the fixed block 4, 7 is a housing, 10 is a tightening screw, 11 is a tightening screw hole, 41 is a U-shaped band-shaped flat plate, and 42 is a prism. The fixed block 4 is composed of a U-shaped belt-like flat plate 41 and a square column 42. Figure 2 is a cross-sectional view after parts are installed, taken along line A-A in Figure 1.
Reference numeral 8 indicates a slope of the recessed portion of the housing, and reference numeral 9 represents a wall surface of the recessed portion of the housing on the flange attachment side.

けてある。 A square column 42 is integrally provided at each tip of the U-shaped band-like flat plate 41 of the fixed block 4, and a tightening screw hole 11 is provided in the axial direction of the square column 42, and a flange guide is provided on the surface on the power module side. A guide pin 6 fits into the hole 3, and a slope 5 similar to the slope 8 of the recess of the housing 7 is formed on the opposite surface. Further, as shown in FIG. 2, two tapped holes into which the tips of the tightening screws 10 are screwed are provided at the bottom of the housing recess.

ねじ込むことにより行われる。 The power module 1 is fixed as shown in FIGS. 1 and 2 by aligning the guide hole 3 of the flange 2 with the guide pin 6 of the fixing block 4, housing it in the housing 7, and fixing it with the tightening screw 10. Fix block 4. At this time, by tightening the tightening screw 10, a force is generated in the direction of pressing the flange 2 by the case slope 8 and the slope 5 of the fixing block 4, and the flange 2 is fixed in close contact with the wall surface 9 of the case. This tightening is performed by screwing the tightening screw 10 into a tap hole provided at the bottom of the housing recess.

である。 The reason why the guide hole 3 of the flange 2 and the guide pin 6 of the fixed block 4 are aligned is mainly to prevent the power module 1 from escaping in the vertical direction.

又、筐体のフランジ対向面の傾斜が大きいとき

傾斜とすることにより補正される。 Further, when the inclination of the surface of the housing facing the flange is large, it can be corrected by making the surface of the prism 42 on the guide pin side an inclination commensurate with the inclination.
