[0002] The junction box for electric power supply device is an important electrical component used to protect and connect wires. It is widely used in power systems, railways, petrochemical and other industries. Since most of the junction boxes currently have poor heat dissipation performance during use and cannot dissipate heat in time, and the space inside the junction box is large, it is very easy for humid gas to enter. Once the terminal is in a humid environment for a long time, water vapor will be generated due to poor heat dissipation, and then water will accumulate on the terminal, which greatly improves the safety of the junction box and greatly increases the incidence of safety accidents. Therefore, a junction box for electric power supply device that avoids water accumulation on the terminal is proposed. Summary of the invention

At the same time, the heater works together to keep the outer surface of the terminal dry. When the box door is closed, the sealing ring expands under the action of pressure, which has a certain sealing effect. When the fan blades rotate, they drive the scraper to remove dust, which greatly improves the heat dissipation effect of the fan blades. Through mutual cooperation, the humidity inside the box is greatly reduced.

When the two clamping plates are closer to each other, the cables will be clamped and fixed to prevent the cables from being pulled out of the junction box by external forces.

[0008] Furthermore, the adjustment component includes a worm, and the left and right sides of the outer surface of the worm are rotatably connected to the left and right sides of the inside of the box.

When the two clamping plates move closer to each other, they clamp and fix the cable to prevent the cable from being pulled out of the junction box by external force, thereby greatly improving the stability and reliability of the equipment and providing a certain guarantee for the stable transmission of the equipment.

[0012] (3) The present invention sets an adjustment component, specifically, by rotating the knob 2 clockwise to drive the worm to rotate, and the rotation of the worm will drive the worm wheel to rotate at the same time. Then, the threaded rod 2 will drive the adjustment plate to move together through the rotation of the worm wheel. When the adjustment plate moves, it will drive a number of sliding bars to slide inside the inclined slide groove 2. Due to the inclined setting of the inclined slide groove 2, when the inclined slide groove 2 moves upward, it will drive them to move closer to each other. Conversely, when the inclined slide groove 2 moves downward, the sliding bars will move away from each other. When the sliding bar moves, it will drive the cable management ring to move together. During the movement of the cable management ring, it will drive the cables to move, so as to adjust the distance between the cables, reduce the short circuit accidents caused by the small distance between the cables, and greatly improve the practicality of the equipment.

[0019] The two groups of anti-slip components 3 are symmetrically arranged with the box body 111 as the center. The two groups of anti-slip components 3 include the same parts. The anti-slip component 3 located on the left side includes a support plate three 312, the inner wall of the support plate three 312 is fixedly connected to the outer surface of the wiring tube 115, the front of the support plate three 312 is fixedly connected to the support plate two 311, the top of the support plate two 311 is fixedly connected to the support frame 318, the support plate two 311 is internally rotatably connected to a threaded rod one 319, the threaded rod one 319 penetrates the support plate two 311 and extends to the top of the support frame 318, the inside of the support frame 318 is rotatably connected to the top of the outer surface of the threaded rod one 319, the top of the threaded rod one 319 is fixedly connected to a knob one 313, and the bottom of the support plate two 311 A movable bracket 314 is provided, and the interior of the movable bracket 314 is connected to the bottom thread of the outer surface of the threaded rod 319. The knob 313 is turned clockwise to drive the threaded rod 319 to rotate. When the threaded rod 319 rotates, the movable bracket 314 is driven to move upward. At this time, the oblique slide groove 315 moves the tops of the two support rods 316 away from each other through the movable bracket 314. When the tops of the two support rods 316 move away from each other, the two clamping plates 317 are driven to approach each other. When the two clamping plates 317 approach each other, the cables are clamped and fixed to prevent the cables from being pulled out of the junction box 119 by external force, thereby greatly improving the stability and reliability of the equipment and providing a certain guarantee for the stable transmission of the equipment.

[0020] The front and back sides of the movable bracket 314 are provided with an oblique slide groove 315, and the front and back sides of the left side of the support plate 312 are rotatably connected to support rods 316 through pins. The right sides of the two support rods 316 are slidably connected to the inside of the oblique slide groove 315 through pins, and the corresponding sides of the two support rods 316 are fixedly connected with a clamping plate 317.

[0021] The adjusting assembly 4 includes a worm 412, the left and right sides of the outer surface of the worm 412 are rotatably connected to the left and right sides of the inside of the box 111, a knob 2 411 is provided on the left side of the box 111, the inside of the knob 2 411 is fixedly connected to the left side of the outer surface of the worm 412, a worm wheel 418 is provided inside the box 111, the outer surface of the worm wheel 418 is meshed with the outer surface of the worm 412, the knob 2 411 is rotated clockwise to drive the worm 412 to rotate, and the worm 412 will also drive the worm wheel 418 to rotate, then the threaded rod 2 417 will drive the adjusting plate 414 to rotate together through the worm wheel 418. When the adjusting plate 414 moves, it will drive several slide bars 420 to slide inside the oblique slide groove 415. Due to the oblique setting of the oblique slide groove 415, when the oblique slide groove 415 moves upward, it will drive 410 to move closer to each other. On the contrary, when the oblique slide groove 415 moves downward, the slide bars 420 move away from each other. When the slide bar 420 moves, it will drive the wire management ring 419 to move together. During the movement of the wire management ring 419, it will drive the cables to move, so as to adjust the distance between the cables and reduce the short circuit accidents caused by the small distance between the cables, thereby greatly improving the practicality of the equipment.

[0023] When in use, the starting motor 211 drives the rotating shaft 212 to rotate. The rotating shaft 212 drives the fan blades 213 to rotate at the same time. The fan blades 213 generate a certain amount of air while rotating and dehumidify the inside of the box body 111. At the same time, the heater 118 on the surface of the terminal post 117 works to keep the outer surface of the terminal post 117 dry and reduce the retention of water vapor on the outer surface of the terminal post 117. At the same time, when the fan blades 213 rotate, the scrapers 217 are affected by the centrifugal force to move away from each other and slide on the outer surface of the support rod 215. When the scrapers 217 slide, they squeeze the spring 216, and the spring 216 is limited by the fixing plate 214 to shrink and accumulate force. When the fan blades 213 stop rotating, the scrapers 217 are removed from the fan body 211. The plate 217 will be reset by the rebound force of the spring 216. When the scraper 217 is reset, the outer surface of the fan blade 213 will be scraped to achieve a certain dust removal effect. At the same time, after the cable is connected to the junction box 119, the cable passes from the inside of the cable management plate 413 to the inside of the wiring tube 115. At this time, the knob 1 313 can be turned clockwise to drive the threaded rod 1 319 to rotate.

At this time, the oblique slide groove 1 315 will move together with the movement of the movable bracket 314 When the inclined slide groove 1 315 moves, the tops of the two support rods 316 will be driven away from each other. Since the middle part of the support rod 316 is rotatably connected to the support plate 2 311 through the pin shaft, when the tops of the two support rods 316 move away from each other, the two clamping plates 317 will be driven to move closer to each other. When the two clamping plates 317 move closer to each other, the cables will be clamped and fixed to prevent the cables from being pulled out of the junction box 119 by external force. At the same time, the distance between the cables can be adjusted by turning the knob 2 411. Specifically, the knob 2 411 is turned clockwise to drive the worm 412 to rotate. When the worm 412 rotates, the worm wheel 418 is driven to rotate. Then, the threaded rod 2 417 rotates through the worm wheel 418 to drive the connecting block 416 to move upward, and the connecting block 416 moves upward. When the adjusting plate 414 moves, the adjusting plate 414 will be driven to move together. When the adjusting plate 414 moves, the inclined slide groove 415 will be driven to move. At this time, a plurality of slide bars 420 will slide inside the inclined slide groove 415. Due to the inclined setting of the inclined slide groove 415, when the inclined slide groove 415 moves upward, the 410 will be driven to move closer to each other. On the contrary, when the inclined slide groove 415 moves downward, the slide bars 420 will move away from each other. When 410 moves, the cable management ring 419 will be driven to move together. During the movement of the cable management ring 419, the cables will be driven to move. While adjusting the cable spacing, the interior of the box 111 can be observed through the visual window 113. A plurality of heat dissipation holes 114 are provided on the left and right sides of the box 111.It is convenient to ventilate and dissipate heat inside the box 111, and a drainage hole 120 is opened at the bottom of the box 111 to facilitate the drainage of accumulated water and prevent the residual accumulated water from inducing water vapor. When the box door 112 is closed, the sealing ring 121 will contact the front of the box 111, and the sealing ring 121 will expand under the action of pressure, which has a certain sealing effect.
