when the rear side edge of the front cover 5 reaches the second positioning mark 314, the third folded edge 57 is positioned outside the front panel 8 and connected to the front panel 8, and the front cover 5 is completely installed.

When the front side edge of the rear cover plate 7 is located at the first positioning mark 313, the head 101 of each rear first jaw 71 passes through the corresponding rear first clamping groove 312, and each leg 102 is located in the corresponding first end 301; the head 101 of each third jaw 72 passes through the corresponding third slot 611, and each leg 102 is located within the corresponding first end 301.

Pushing the rear cover plate 7 forward to the front side edge thereof to reach the second positioning mark, the mounting of the rear cover plate 7 is completed, and the leg portion 102 of each rear first claw 71 is located in the corresponding second end portion 302; the head 101 of each third jaw 72 is located within the corresponding second end 302. The positioning and mounting efficiency of the rear cover plate 7 is improved.

Preferably, an inward tenth folded edge 76 is provided at the rear side edge of the rear cover plate 7; the opening of the box body also comprises an upper opening and a rear opening; the box body comprises a cross beam 10; the beam 10 is located between the upper opening and the rear opening, and is respectively connected with the first side plate 3 and the electrical box 6. The tenth flange 76 is located on the outer side of the cross member 10 and is fixedly connected to the cross member 10.

In the second embodiment, referring to fig. 2, 3, 4, 5, 6 and 7, the opening of the box body further includes an upper opening and a rear opening; the box body comprises a cross beam 10; the beam 10 is located between the upper opening and the rear opening, and is respectively connected with the first side plate 3 and the electrical box 6.

The cover plate comprises a front cover plate 5 and a rear cover plate 7; the electrical box 6 comprises a rear side plate 62 which constitutes a rear side wall of the electrical box 6; the rear cover 7 is connected to the rear opening and forms a rear side wall of the box body together with the rear side plate 62. The rear first engaging groove 312 is a long through hole along the vertical direction of the first folding edge 31; the rear side plate 62 of the electrical box 6 is provided with a third card slot 611 which has the same structure and the same direction as the rear first card slot 312, and the first end 301 of the third card slot is positioned above the second end 302. The structure of the rear cover plate 7 refers to the first embodiment.

During installation, first, the head 101 of each rear first jaw passes through the first end 301 of the corresponding third slot 611, so that the leg 102 of each rear first jaw 71 is located in the first end 301 of the corresponding third slot 611; the head 101 of each third jaw 72 is inserted through the first end 301 of the corresponding rear first card slot 312 such that the leg 102 of each third jaw 72 is located within the first end 301 of the corresponding rear first card slot 312.

Then, the rear cover plate 7 is pushed downward, so that the leg portion 102 of each rear first claw 71 moves into the second end portion 302 of the corresponding third catching groove 611, and the leg portion 102 of each third claw 72 moves into the second end portion 302 of the corresponding rear first catching groove 312, so that the tenth flange 76 is positioned on the upper side of the cross member 10 and connected to the cross member 10.

Referring to fig. 1, 2, 3, 4, 5, 6 and 7, the rear cover 7 of the present embodiment has the same structure as the rear cover 7 of the first embodiment, and can be shared, except that the rear cover 7 of the first embodiment is inverted, the tenth fold 76 is changed from being located at the rear side of the cross beam 10 to being located at the upper side of the cross beam 10, and each third latch 72 is located at the left end of the rear case and connected to the corresponding rear first latch 312; each rear first jaw 71 is located at the right end of the rear case and connected to the corresponding third groove 611. The related features of the present embodiment other than the structure of the rear cover 7 and its connection refer to the first embodiment.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
