[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention sets a fixing component. When the junction box is in use, the heat emitted by the fuse is transferred to the surface of the heat conductive sheet through the heat dissipation frame, wherein the heat conductive sheet is designed to be in a wave shape, so that the contact area between the heat conductive sheet and the air becomes larger. Subsequently, when the heat dissipation component is in operation, the hot air inside the heat dissipation frame can diffuse to the outside of the protective plate through the heat dissipation holes, thereby preventing the fuse from being damaged due to excessive temperature during operation.

[0017] 2. The present invention sets a heat dissipation component, and the driving motor drives the cooling component to operate through the rotating shaft. At this time, the rotating shaft drives the guide fan to rotate through the transmission shaft. When the guide fan rotates, it can blow the air in the ventilation duct to the side close to the dustproof component. At the same time, a side baffle is set to prevent the air in the ventilation duct from being blown out from the ventilation hole. At this time, the air flow rate in the ventilation duct is fast and the pressure is small, so that the hot air outside the ventilation duct can enter the interior of the ventilation duct through the ventilation hole, thereby bringing the hot air in the box out through the ventilation duct.

[0018] 3. The present invention sets a cooling component. When the hot air enters the ventilation duct through the ventilation hole, the hot air first passes through the surface of the condenser. At this time, part of the heat in the hot air is transferred to the surface of the condenser, thereby cooling the blown hot air. At the same time, the rotating shaft drives the fan blades to rotate, and blows the external cold air into the bypass duct through the protective shell, which speeds up the flow rate of the air in the bypass duct, thereby allowing the heat of the condenser to be transferred to the bypass duct, so that the air in the bypass duct can take out the heat when flowing, thereby cooling the condenser.

[0019] 4. The present invention provides a dust-proof component, so that the air in the bypass pipe is blown into the ventilation shell, and at the same time, the hot air in the ventilation pipe enters the filter cartridge. At this time, the filter cartridge can filter the dust mixed in the hot air. The filtered air enters the ventilation shell after passing through the filter cartridge, and is finally discharged to the outside through the side support ring, thereby filtering the blown hot air.

[0020] 5. The present invention provides a dustproof component. When the knob is rotated, the knob gradually separates from the side support ring. At this time, the sealing block moves with the knob, and drives the scraper ring to slide along the inner side of the filter cartridge through the connecting rod. The scraper ring can scrape off the dust attached to the surface of the filter cartridge during the sliding process, thereby cleaning the filter cartridge.

[0021] 6. The present invention arranges a wiring assembly. When wiring, the wire harness passes through the explosion-proof through-hole. At this time, the wire barrel is rotated so that the threaded block pushes the wire barrel upward along the inner wall of the explosion-proof through-hole. At this time, the top block and the top ring squeeze each other, forcing the elastic clamp to be squeezed and deformed. At this time, the tops of the four elastic clamps approach each other and clamp the wire harness, thereby fixing the position of the wire harness to prevent the wire harness from being separated from the fuse when the junction box is in use.

[0022] 7. The present invention arranges a sealing assembly. After the sealing assembly is fixed, if the operator needs to observe the situation inside the box, the sliding shell can be driven by the handle to slide downward along the surface of the annular rod. At this time, as the sliding shells on both sides move away from each other, the staff can observe the situation inside the box through the fan-shaped observation window on the top of the limit block, which provides convenience for the staff's maintenance work.

[0023] 8. The present invention provides a sealing assembly, fixes the annular rod through a fixing block, and drives the sliding shell to reset through a compression spring provided on the outside of the annular rod, so that the sliding shell can block the fan-shaped observation window involved in the cover plate surface when closed, thereby protecting it.

[0044] Working principle:

[0045] When in use, the box 1 is fixed on the wall through the side ear 4 shell, and then the wire harness passes through the wiring assembly 3 and is connected to the fuse 6 mounted on the surface of the fixing assembly 5. After the wire harness is connected, the box 1 is sealed through the sealing assembly 2, wherein the heat dissipation assembly 7 can dissipate heat when the junction box is in use;

[0046] When the junction box is in use, the heat emitted by the fuse 6 is transferred to the surface of the heat conductive sheet 54 through the heat dissipation frame 52, wherein the heat conductive sheet 54 is designed to be in a wave shape, so that the contact area between the heat conductive sheet 54 and the air becomes larger. Then, when the heat dissipation assembly 7 is in operation, the hot air inside the heat dissipation frame 52 can diffuse to the outside of the protective plate 51 through the heat dissipation holes 53, thereby preventing the fuse 6 from being damaged due to excessive temperature during operation;

[0047] When the heat dissipation assembly 7 is in use, the driving motor 72 located inside the protective shell 71 drives the fan blades 74 to rotate through the rotating shaft 73, and drives the cooling component 75 to operate at the same time. At this time, the rotating shaft 73 drives the guide fan 755 to rotate through the transmission shaft 754. When the guide fan 755 rotates, it can blow the air in the ventilation pipe 751 to the side close to the dustproof component 76. At the same time, a side baffle 757 is provided to prevent the air in the ventilation pipe 751 from being blown out from the ventilation hole 756. At this time, the air flow rate in the ventilation pipe 751 is fast and the pressure is low, so that the hot air outside the ventilation pipe 751 can enter the ventilation pipe 751 through the ventilation hole 756, thereby taking the hot air in the box body 1 out through the ventilation pipe 751;

[0048] When the hot air enters the ventilation pipe 751 through the ventilation holes 756, the hot air first passes through the surface of the condensing sheet 752. At this time, part of the heat in the hot air is transferred to the surface of the condensing sheet 752, thereby cooling the blown hot air. At the same time, the rotating shaft 73 drives the fan blades 74 to rotate, and the external cold air is blown into the bypass pipe 753 through the protective shell 71, thereby accelerating the flow rate of the air in the bypass pipe 753, thereby allowing the heat of the condensing sheet 752 to be transferred to the bypass pipe 753, so that the air in the bypass pipe 753 can take out the heat when flowing, thereby cooling the condensing sheet 752;

[0049] When the dust-proof component 76 is in use, the air in the bypass pipe 753 is blown into the ventilation shell 761, and the hot air in the ventilation pipe 751 enters the filter cartridge 762. At this time, the filter cartridge 762 can filter the dust mixed in the hot air. The filtered air enters the ventilation shell 761 after passing through the filter cartridge 762, and is finally discharged to the outside through the side support ring 763, thereby filtering the blown hot air;

[0050] When the knob 764 is rotated, the knob 764 gradually separates from the side support ring 763. At this time, the sealing block 765 moves together with the knob 764, and drives the scraper ring 767 to slide along the inner side of the filter cartridge 762 through the connecting rod 766. The scraper ring 767 can scrape off the dust attached to the surface of the filter cartridge 762 during the sliding process, thereby cleaning the filter cartridge 762.

[0051] When wiring, the wire harness passes through the explosion-proof through-head 31. At this time, the wire harness barrel 33 is rotated so that the threaded block 32 pushes the wire harness barrel 33 upward along the inner wall of the explosion-proof through-head 31. At this time, the top block 36 and the top ring 34 are pressed against each other, forcing the elastic clamping plate 35 to be squeezed and deformed. At this time, the tops of the four elastic clamping plates 35 are close to each other and clamp the wire harness, thereby fixing the position of the wire harness to prevent the wire harness from being separated from the fuse 6 when the junction box is in use;

[0052] After the sealing assembly 2 is fixed, if the operator needs to observe the situation inside the box body 1, the operator can use the handle 25 to drive the sliding shell 24 to slide downward along the surface of the annular rod 23. At this time, as the sliding shells 24 on both sides move away from each other, the operator can observe the situation inside the box body 1 through the fan-shaped observation window on the top of the limit block 27, which provides convenience for the operator's maintenance work;

[0053] Among them, the annular rod 23 is fixed by setting a fixing block 22, and the sliding shell 24 is driven to reset by a compression spring 26 set on the outside of the annular rod 23, so that the sliding shell 24 can block the fan-shaped observation window involved in the surface of the cover plate 21 when closed, thereby protecting it.
