Arc, but the general arc-shaped housing will encounter the following problems when assembling PCBA boards:

1) When pipe nails are used, since the pipe nails and the lower bottom are riveted, in the arc shape, the position of the pipe nails is just on the arc surface, so they cannot be riveted: and the riveted holes can be seen directly on the back, which is not beautiful ;

2) When the bridge position is used, the bridge position cannot be punched out on the arc surface, and the holes left during punching can be seen intuitively on the same back side, and the aesthetics is very poor;

3) When the direct 90-degree hemming structure is adopted, it will cause interference between the PCBA and the fan structure of the upper cover, so the height of the PCBA board must be limited, and it is impossible to use a general-purpose PCBA board, but it is necessary to develop a PCBA board with a suitable size, which is costly and unsuitable Promote.

Detailed ways

In order to make the above purpose, features and advantages of the utility model more obvious and understandable, the utility model will be further described in detail below in conjunction with specific embodiments.

As shown in Figure 1, the switching power supply housing for a desktop computer with a circular arc shape of the present invention includes a housing body; the housing body is composed of an upper cover and a lower cover,

As shown in Figure 2, the upper cover is formed by vertically connecting the front side 101, the upper side 102 and the rear side 103 successively. The upper side 102 is provided with a plurality of assembly holes 2 fixedly connected with the lower cover. 102 is provided with a number of cooling holes 3; the front side 101 and the upper side 102, the upper side 102 and the rear side 103 are connected by arcs; It is formed by connecting vertically with the right side 703 in turn, and the upper ends of the left side 701 and the right side 703 are provided with protruding sides 4, and the protruding sides 4 are provided with corresponding mounting holes 2. The second assembly hole 5 of the second assembly hole 5, screws and other fixing elements pass the assembly hole 2 and the second assembly hole 5 to integrate and fix the upper cover and the lower cover into a shell body with six sides, which protects the power supply of the computer; the left side 701 and the bottom surface 702, and the bottom surface 702 and the right side 703 are connected by circular arcs; in this embodiment, four assembly holes 2 combined with the left and right protective shells are provided on the upper cover for screw mounting, and a circular heat dissipation is designed on the top Holes 3 are used for air intake.
