Problems solved by technology
The electronic equipment in the power distribution box generates a lot of heat. In order to meet the heat dissipation requirements of the power distribution box under high power, most power distribution boxes use cooling holes to dissipate heat. The heat dissipation holes make it easy for dust to enter the inside of the power distribution box, affecting the internal electronic equipment. stability

Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0017] Reference Figure 1 to Figure 4 , A dustproof power distribution box box of the present invention includes a box shell 1, a dust cover 2 and a heat dissipation cover 3; the upper end of the box shell 1 is an opening; the dust cover 2 is connected to the upper end of the box shell 1 and Covering the opening, the contour of the dust cover 2 matches the box shell 1, and can be combined without end difference. In this example, the dust cover 2 and the box body 1 are in a rectangular parallelepiped shape as a whole. The bottom surface of the dust cover 2 is in the shape of an upwardly arched cone, specifically a quadrangular pyramid, which extends upwards from the four sides of the bottom surface, the top of the cone is provided with a through hole 21, the upper end of the dust cover 2 is an opening; the heat dissipation cover The plate 3 covers the opening at th...

The invention discloses a dustproof power distribution box, and the power distribution box comprises a box case, a dustproof cover, and a heat dissipation cover plate. The upper end of the box case isopened, and the dustproof cover is connected to the upper end of the box case, and covers the opening. The bottom surface of the dustproof cover is shaped like a cone which arches upwards. The top ofthe cone is provided with a through-flow hole, and the upper end of the dustproof cover is opened. The heat dissipation cover plate covers the opening at the upper end of the dustproof cover, and isprovided with a plurality of heat dissipation holes. According to the invention, the cone which arches upwards enables the dust to be stacked at the bottom of the cone, thereby preventing the dust from being stacked on electronic equipment in the box case. Moreover, the design of the dustproof cover enables the overall heat dissipation space to be increased. Through the communication of the through-flow hole and the heat dissipation holes, hot air can be automatically released upwards, and the heat dissipation effect is improved.
Description
Technical field [0001] The invention relates to a power distribution box, in particular to a dustproof power distribution box. Background technique [0002] At present, the distribution box assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or screen according to electrical wiring requirements to form a low-voltage power distribution device. With the development of urban construction, The demand for distribution boxes is also increasing. The electronic equipment in the distribution box generates a lot of heat. For the heat dissipation requirements of the distribution box under high power, most of the distribution boxes use heat dissipation holes to dissipate heat. The heat dissipation holes cause dust to enter the distribution box easily and affect the internal electronic equipment The stability. Summary of the invention [0003] The present invention aims to solve the above technical problems at ...
