The third installation area is also provided with a protective plate 73. The protective plate 73 is fixed to the mounting plate 7, and a heater 86 is provided on the surface of the protective plate 73 facing away from the mounting plate 7 to prevent the humidity in the cabinet 1 from being too high.

[0040] It should be noted that the types of electrical components of the distribution box in actual application are not limited to the description in this embodiment, and should be subject to actual application.

[0041] Specifically, in this embodiment, the base 10 is further provided with second columns 21 located inside the cabinet 1 and supporting and fixing the two side plates 12. For example, two second columns 21 corresponding left and right are provided at the front position of the upper surface of the base 10, and the two second columns 21 correspond to the two first columns 20 one by one in the front and back. The two second columns 21 are both close to the cabinet door 4 and are located between the first column 20 and the cabinet door 4. The bottoms of the two second columns 21 can also be welded to the upper surface of the base 10. The shape of the second column 21 is L-shaped. The base 10 and the first column 20 and the second column 21 thereon form a metal skeleton for stably installing the back panel 11 and the side plates 12. The inner side surface of the side plate 12 at the front position is also provided with a positioning stud 1210. The inner side surface of the side plate 12 at the front position is parallel to the side of the second column 21. After the rear end of the side plate 12 is installed in place, the two can be fastened together by the second fastener 6.

[0042] Furthermore, an instrument door 9 is installed on the front side of one of the second columns 21. For example, a second rotating connector 32 is installed on the front side of the second column 21 connected to the left side plate 12, and then the left side of the instrument door 9 is connected through the second rotating connector 32 to rotatably install the instrument door 9 inside the cabinet 1. The second rotating connector 32 is a door hinge. The instrument door 9 is located between the mounting plate 7 and the cabinet door 4. The right side of the instrument door 9 is fixed to the front side of the other second column 21 by the first fastener 5 or the second fastener 6 and can be disassembled. Instrument components are provided on the surface of the instrument door 9 facing the cabinet door 4 (i.e., the front surface of the instrument door 9), and an observation window 42 is also provided on the cabinet door 4 at the position corresponding to the instrument components. The observation window 42 is a visible window, such as a glass window.

[0043] In this embodiment, the first fastener 5 is a blind rivet screw, which is suitable for connecting and fixing between two thin plates and has good connection stability. The second fastener 6 is a connecting screw, which is suitable for threaded assembly with threaded holes and has simple disassembly and assembly operations.

[0044] It should be noted that the method of connecting the door with a door hinge or a door shaft is relatively common in the prior art. During specific implementation, reference can be made to the prior art, and it will not be elaborated in this embodiment.

[0045] Specifically, in this embodiment, a box cover 13 is provided at the top of the back panel 11 and the two side panels 12 (i.e., the box body 1). The outer edge of the box cover 13 extends relatively outwards from the edges of the back panel 11 and the two side panels 12. The upper surface of the box cover 13 protrudes and forms a first inclined surface and a second inclined surface. The first inclined surface faces forward, and the second inclined surface faces backward, serving the functions of rain prevention, water accumulation prevention, and shielding. Axial flow fans 14 are correspondingly provided on the two side panels 12 near the box cover 13, serving the function of ventilation. Waterproof covers 15 are provided on the outer surfaces of the two side panels 12 at positions corresponding to the axial flow fans 14 on the same side. The openings of the waterproof covers 15 face downward and communicate with the air outlet ends of the axial flow fans 14, which can not only prevent rainwater from entering the box body 1 through the channels where the axial flow fans 14 are located but also ensure effective ventilation.

[0046] In this embodiment, the back panel 11, the side panels 12, the box cover 13, and the box door 4 are all made of SMC insulating composite material, that is, the back panel 11, the side panels 12, the box cover 13, and the box door 4 are all made of SMC insulating composite material, which has the characteristics of dust prevention, water prevention, explosion prevention, acid resistance, alkali resistance, heat insulation, condensation prevention, stable quality, and complete insulation and non-conductivity, and is widely used. The SMC insulating composite material uses unsaturated polyester resin as an adhesive, adds glass fiber, filler, pigment, and other additives, impregnates glass fiber yarn, covers both sides with a film to form a "sandwich structure", and is obtained by using the SMC material compression molding technology after curing treatment until it does not stick to the hand.

[0047] Therefore, the outdoor distribution box using SMC composite material as the shell material overcomes the disadvantages of the outdoor distribution box using metal material as the shell material, such as easy rust and poor heat insulation and heat preservation performance, and has the performance of high temperature resistance and effective prevention of water vapor condensation.

[0048] It should be noted that since the outdoor distribution box is usually in a harsh environment of sunlight and rain, during actual application, electrical appliances suitable for cooling and dehumidification can also be configured according to the temperature and humidity conditions inside the outdoor distribution box to ensure the normal working state of each electrical component inside the outdoor distribution box.

[0049] It should be understood that for ordinary technical workers in the field, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
