Moisture-proof distribution box

Abstract

The invention discloses a moisture-proof distribution box comprising a bottom plate, a top plate and four side plates, four angle steels vertically distributed at four corners are detachably fixed on the bottom plate, the side plates are detachably connected among the angle steels to form four box walls of the distribution box, and the top plate detachably covers the tops of the angle steels. Each side plate is formed by detachably combining an outer plate body, a heat preservation plate and an inner plate body, the heat preservation plate is located between the outer plate body and the inner plate body, a grid-shaped window is formed in the outer plate body, and a movable blocking cover is arranged on the outer side of the window. The side plates of the distribution box are formed by combining the outer plate bodies, the inner plate bodies and the middle heat insulation plates, and heat exchange between the outside and the interior of the distribution box is blocked by the heat insulation plates at night in winter, so that the condition that hot air in the distribution box is cooled and liquefied is well improved, and fog water generated on the inner wall of the distribution box is reduced or avoided. Therefore, the problems of corrosion and circuit faults in the distribution box are solved, and the service life of the distribution box is prolonged.

Description

technical field [0001] The invention relates to the field of distribution boxes, in particular to a moisture-proof distribution box. Background technique [0002] Most of the existing distribution boxes are simple metal box structures, and their moisture-proof performance is poor, especially at night in winter, when the outside temperature is very low, and the heat generated by the electrical components in the distribution box makes the internal temperature of the distribution box high. Due to the external temperature of the distribution box, mist is likely to be formed on the inner wall of the distribution box, which will cause corrosion inside the distribution box, affect the service life, and may even cause the failure of the power supply circuit in severe cases. Contents of the invention [0003] The purpose of the present invention is to provide a moisture-proof distribution box to solve the problems raised in the above-mentioned background technology.
