A terminal is fixedly installed on the bottom of the junction box body, and electronic components are fixedly installed inside the junction box body.

[0003] The existing junction box has some obvious shortcomings in actual use. Among them, the filter on the junction box cannot be removed separately, which makes it extremely inconvenient to clean or replace the filter when it absorbs dust and other impurities. Since the filter cannot be removed separately, the entire junction box may need to be disassembled in a complicated manner, which not only consumes time and energy, but may also cause unnecessary damage to other components during the disassembly process. This situation greatly reduces the practicality of the device, causing users to face many troubles during use and unable to conveniently perform filter maintenance work, which in turn affects the overall use effect and life of the junction box. Utility Model Content

[0004] The purpose of the present utility model is to provide a dust-proof and heat-dissipating photovoltaic junction box for photovoltaic power generation. By providing a disassembly mechanism, the problem of the filter on the junction box not being able to be disassembled separately is solved, which makes it extremely inconvenient to operate when the filter absorbs dust and other impurities and needs to be cleaned or replaced. Since the filter cannot be disassembled separately, it may be necessary to perform complicated disassembly operations on the entire junction box, which not only consumes time and energy, but may also cause unnecessary damage to other components during the disassembly process. This situation greatly reduces the practicality of the device, causing users to face many troubles during use and being unable to conveniently perform filter maintenance work, which in turn affects the overall use effect and life of the junction box.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a dustproof and heat-dissipating photovoltaic junction box for photovoltaic power generation, comprising a junction box, on which two disassembly mechanisms and a configuration mechanism are provided.

[0007] The heat dissipation frame is fixedly provided with a plurality of sliding blocks, and the right ends of the sliding blocks are fixedly connected to the inner wall of the heat dissipation frame, and the right ends of the sliding blocks are fixedly connected to the plurality of sliding blocks. The plurality of sliding blocks are connected to the plurality of limit rods, and the plurality of limit rods extend outside the cross sliding frame and are slidably connected to the cross sliding frame.

[0008] Furthermore, a turntable is slidably connected to the outer wall of the screw, and a nut is threadedly sleeved on the outer wall of the screw.

[0009] Furthermore, the configuration mechanism includes a wiring base fixedly connected to the inner wall of the bottom of the junction box, and two sliding rods 2 are fixedly connected to the inner wall of the bottom of the junction box, and the two sliding rods 2 both penetrate the wiring base, and the outer wall sliding sleeves of the two sliding rods 2 are provided with a wiring top seat, and the wiring top seat is adapted to the wiring base, and the inner walls of the wiring base and the wiring top seat are provided with a number of wiring grooves, and the inner walls of several of the wiring grooves are provided with wires, and the front and rear ends of several of the wires extend outside the junction box and are slidably connected to the junction box.

[0010] Furthermore, the top ends of the two sliding rods are fixedly connected to a U-shaped plate, a pull rod is slidably connected to the U-shaped plate, and the bottom ends of the pull rods are fixedly connected to the wiring top seat.

[0011] Furthermore, the outer walls of the two sliding rods 2 are both wound with springs, one end of the two springs is fixedly connected to the wiring top seat, and the other end of the two springs is fixedly connected to the U-shaped plate.

[0012] Furthermore, a slide groove is provided on the top of the junction box, a protective plate is slidably connected to the inner wall of the slide groove, a latch is slidably connected to the front of the junction box, and a rear end of the latch extends into the protective plate.

[0013] The utility model has the following beneficial effects:

[0014] (1) The utility model is provided with a disassembly mechanism. When the filter needs to be disassembled, the turntable on the screw can be rotated. When the turntable rotates, the screw will rotate accordingly, thereby driving the arc groove disc on it to rotate. During the rotation process, the arc groove disc will adapt to the toggle rod sliding on the slider in the cross slide frame. When the two are adapted in place, the slider will drive the limit rod on it to move under its action, so that the limit rod releases the limit on the circular groove on the heat dissipation frame. In this way, the disassembly operation of the filter can be completed. Through this setting, the problem of being unable to clean due to the inability to disassemble the filter can be effectively reduced, ensuring that the filter always maintains a good filtering effect, extending the service life of the equipment, and improving the working efficiency of the equipment.

[0015] (2) The present invention sets up a configuration mechanism. If it is necessary to connect the wires, the pin on the protective plate can be pulled outward first. After the pin is pulled out, the protective plate can slide outward in the slide groove to open the junction box, which provides convenience for the wiring operation. Then, the pull rod can be pulled upward. When the pull rod is pulled, the two slide bars 2 will be used to make the junction top seat move upward and separate from the junction base, thereby creating enough space for placing the wires. At the same time, during the upward movement of the junction top seat, the junction top seat will also compress the springs on the outer walls of the two slide bars 2. At this time, the springs will accumulate energy to provide power for the subsequent reset operation. Then, the two ends of the wiring heads that need to be connected together can be placed in the wiring groove. After placement, the pull rod can be released. At this time, the springs will release the accumulated energy and cooperate with the two slide bars 2 to push the junction top seat toward the junction base. In this way, the wires at both ends can be connected together. Through this setting, the convenience and efficiency of wire connection can be greatly improved, the operation time and labor cost can be reduced, and at the same time, the firmness and stability of the wire connection can be ensured, providing reliable power guarantee for the normal operation of the equipment.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
