[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 An electromagnetic shielding insulating box includes a box body 1 and a cover 6 installed on one side of the upper end of the box body 1. The box body 1 and the cover 6 are equipped with locking structures for mutual use. A bracket is fixed to the lower end of the box body 1, and a heat-conducting plate 9 is fixed to the lower end face of the box body 1. Heat dissipation fins 12 are fixed at equal intervals on the lower end face of the heat-conducting plate 9. A grounding component is fixed to one end of the heat-conducting plate 9. Two support blocks 7 are symmetrically fixed to the inner walls of the box body 1 on opposite sides. Rubber pads 8 are fixed to the upper ends of the four support blocks 7. Electronic components can be placed on the support blocks 7 and connected to the support blocks 7 with screws to fix the electronic components. A wire hole 2 is opened on the box body 1, and a rubber sleeve is provided at the wire hole 2. After the power wire of the component is passed through the wire hole 2 and laid out, the gap in the wire hole 2 can be filled with sealant to ensure the airtightness of the box body 1. The inner walls of the box body 1 and the cover 6 are coated with an electromagnetic shielding coating. The electromagnetic shielding coating can shield electromagnetic waves, thereby ensuring the safe operation of the electronic components.

[0023] The bracket includes four support legs 3 fixed at the four corners of the lower end face of the box 1. The lower ends of the four support legs 3 are connected to a fixing plate 4. Fixing holes are opened at the four corners of the fixing plate 4. The fixing plate 4 can be fixed to the installation position by bolts through the fixing holes.

[0024] A U-shaped plate 10 is fixed to the upper end of the fixed plate 4, and two fans 11 are symmetrically fixed to the upper end of the horizontal section of the U-shaped plate 10.

[0025] The grounding assembly includes a metal sheet 14 connected to the heat-conducting plate 9, and a grounding wire 13 is soldered onto the metal sheet 14. By connecting the grounding wire 13 to the ground, static electricity on the box 1 can be eliminated, thus preventing static electricity from affecting the components in the box 1.

[0026] The locking structure includes a first connecting block 5 fixed to the middle of one side of the lid 6, a locking bolt 15 screwed onto the first connecting block 5, and a second connecting block 16 fixed to one side of the outer wall of the box body 1. The second connecting block 16 has a screw hole that forms a screw connection with the locking bolt 15. After the lid 6 is closed, the locking bolt 15 is screwed onto the second connecting block 16 to achieve screw connection, thereby fixing the lid 6.

[0027] A temperature sensor 19 is fixed to the bottom of one side of the inner wall of the box 1, and a controller 20 is installed on one side of the outer wall of the box 1. The temperature sensor 19 and the two fans 11 are electrically connected to the controller 20.

[0028] Heat can be dissipated from the housing 1 through the heat conduction plate 9 and the heat dissipation fins 12. The temperature inside the housing 1 is detected by the temperature sensor 19 and the temperature information is transmitted to the controller 20. When the temperature is too high, the controller 20 controls the two fans 11 to accelerate the heat dissipation of the heat conduction plate 9 and the heat dissipation fins 12, thereby improving the cooling of the housing 1 and ensuring the stable operation of electronic components inside the housing 1.

[0029] Example 2 is an optimization based on Example 1, specifically:

[0030] A sealing groove 17 is provided at the top opening of the box body 1, and a rubber sealing ring 18 is provided on the edge of the box cover 6 corresponding to the sealing groove 17.

[0031] When the lid 6 is placed on the box body 1, the rubber sealing ring 18 is engaged in the sealing groove 17, achieving a good sealing effect.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
