In the DC stabilized power supply case formed of a bent plate which is bent to the bottom plate side by approximately 90 degrees, an engagement portion for engaging the bottom plate with the bent plate is formed.

[0007]

In order to achieve the above object, the present invention provides a bottom plate attached to a mounting base, a side plate integrally formed in a vertical direction from the bottom plate, to which a power source is attached, and an integral part of the side plate. In a direct-current stabilized power supply case formed of a bent plate bent at approximately 90 degrees to the bottom plate side, an engaging portion for engaging the bottom plate and the bent plate is formed ,
The engaging portion is integrated with the bottom plate and the bending plate, respectively.
It is composed of a pair of formed protruding pieces, and these protruding pieces are
It is made to overlap and adhere.

Further, since it is not necessary to use reinforcing parts such as screws and metal fittings, the cost does not increase.

Reference numeral 15 denotes a bent plate which is also formed of aluminum and is integrally formed with the side plate 13. The bent plate 15 is bent at approximately 90 degrees toward the bottom plate 11. The bottom plate 11, the side plate 13, and the bending plate 15 constitute a DC stabilized power supply case 12 as a whole. Reference numeral 16 denotes a projecting piece formed integrally with the bottom plate 11, and the projecting piece 16 is slightly bent upward.

Reference numeral 17 denotes a projecting piece integrally formed with the bending plate 15, and the projecting piece 17 projects in the horizontal direction. These protruding pieces 16 and 17 are stacked with one protruding piece 16 as an upper part and the other protruding piece 17 as a lower part, and are in close contact with each other. Therefore, these protruding pieces 16 and 17 constitute an engaging portion 18 for engaging the bent plate 15 and the bottom plate 11.
Even if vibration or impact in the direction indicated by the arrow A is applied to the side plate 13, the bent plate 15 and the bottom plate 11 are not separated from each other and are engaged by the projecting pieces 16 and 17 as in the related art. Can be alleviated.

Therefore, it is possible to prevent the bent portion 14 from breaking or cracking. In addition, since it is not necessary to use reinforcing parts such as screws and metal fittings, the cost does not increase. Next, FIG. 3 is a view showing a second embodiment of the present invention. In FIG. 3, reference numeral 21 denotes a bent portion formed integrally with an end of the bottom plate 11, and the bent portion 21 is slightly bent upward.

Reference numeral 22 denotes a bent portion formed integrally with the bending plate 15, and the bent portion 22 is bent in the horizontal direction. The bent portions 21 and 22 are stacked with one bent portion 21 as an upper portion and the other bent portion 22 as a lower portion, and are in close contact with each other. Therefore, these bent portions 21 and 22 constitute an engaging portion 23 that engages the bent plate 15 and the bottom plate 11.

Also in this embodiment, the bent plate 15 and the bottom plate 11
Are engaged, and even if vibration or impact is applied,
4 can be alleviated. As a result, also in this embodiment, the same effect as in the above embodiment can be obtained. Next, FIG. 4 is a view showing a third embodiment of the present invention.

In FIG. 4, reference numeral 31 denotes a projecting piece integrally formed at the end of the bottom plate 11, and the projecting piece 31 is slightly bent upward. Reference numeral 32 denotes an insertion hole formed in the bending plate 15, into which the protruding piece 31 is inserted. These projecting pieces 31 and insertion holes 32 are
An engaging portion 33 that engages the bottom plate 11 with the base plate 5 is formed. The bottom plate 11 and the bending plate 15 are engaged by inserting the protruding piece 31 into the insertion hole 32, and can reduce the stress applied to the bending portion 14 even when vibration or impact is applied.

As a result, in this embodiment, the same effect as in the above embodiment can be obtained. Next, FIG. 5 is a view showing a fourth embodiment of the present invention. In FIG. 5, the bottom plate 1
At one end, concave portions 41 and convex portions 42 are formed alternately.

At the end of the bent portion 15, convex portions 43 and concave portions 44 are formed alternately. Convex portion 42 of bottom plate 11
Is fitted in the concave portion 44 of the bent plate 15, and the convex portion 43 of the bent plate 15 is fitted in the concave portion 41 of the bottom plate 11. These concave portions 41 and 44 and convex portions 42 and 43 are formed by bending plate 15 and bottom plate 1.
1 constitutes an engaging portion 45 that engages the engaging portion 1.

The bottom plate 11 and the bent plate 15 are provided with concave portions 41, 4
4. Engagement at the projections 42 and 43 can reduce the stress applied to the bending portion 14 even when vibration or impact is applied.
As a result, also in this embodiment, the same effect as in the above embodiment can be obtained.

[0020]

As described above, according to the present invention, the bottom and the bent plate are engaged by the engaging portion.
Even when vibration or impact is applied, the stress applied to the bent portion of the bottom plate and the side plate can be reduced, and the occurrence of breakage or cracking of the bent portion can be prevented. Further, since it is not necessary to use reinforcing parts such as screws and metal fittings, the cost does not increase.
