[0019] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model relates to a self-healing device for arc faults in a distribution box, comprising a mounting plate 1, with mounting holes 2 extending through each of the four corners of the mounting plate 1. Three arc fault protector bodies 3 are uniformly fixedly mounted on the front side of the mounting plate 1. Wiring grooves 4 are formed inside the top and bottom of the three arc fault protector bodies 3. Arc-shaped grooves 5 are formed at the top and bottom of the side of the arc fault protector body 3 away from the mounting plate 1, and the arc-shaped grooves 5 are connected to the wiring grooves 4. An adjustment and positioning component 6 is also installed on the front side of the mounting plate 1. In use, through the interaction of the mounting plate 1, mounting holes 2, three arc fault protector bodies 3, wiring grooves 4, arc-shaped grooves 5, and adjustment and positioning component 6, the self-healing device for arc faults in the distribution box can quickly perform wiring operations on multiple arc fault protectors during use, improving work efficiency and thus achieving better practicality.

[0020] The adjusting positioning assembly 6 includes a first strip plate 7 and a second strip plate 8, which are symmetrically fixedly installed on the front side of the mounting plate 1. Three fault arc protection device bodies 3 are located between the first strip plate 7 and the second strip plate 8. Drive shafts 9 are rotatably installed between the top and bottom ends of the first strip plate 7 and the second strip plate 8. Adjusting positioning blocks 10, which have a B-shaped structure, are evenly fixedly installed on the outer sides of the two drive shafts 9. A strip-shaped housing 11 is fixedly installed on the side of the first strip plate 7 away from the second strip plate 8, with one end of the drive shaft 9 extending into the interior of the strip-shaped housing 11 and the other end extending into the side of the second strip plate 8 away from the first strip plate 7. An adjusting shaft 12 is rotatably installed inside the strip-shaped housing 11. The top and bottom of the strip-shaped housing 11 extend to the outer side of the top and bottom of the strip-shaped housing 11, respectively. An adjusting block 13 is fixedly installed on the top of the adjusting shaft 12. A drive bevel gear 14 is symmetrically fixedly installed inside the strip-shaped housing 11 and outside the adjusting shaft 12. A transmission bevel gear 15 is meshed with the outer side of each of the two drive bevel gears 14. The transmission bevel gear 15 is fixedly installed at one end of the transmission shaft 9 inside the strip-shaped housing 11. An arc-shaped groove 18 is symmetrically opened through the inside of the second strip-shaped plate 8. A sliding column 19 is slidably installed through the inside of the arc-shaped groove 18. One end of the sliding column 19 extends to the side of the second strip-shaped plate 8 away from the first strip-shaped plate 7. A movable block 20 is fixedly installed at the end of the transmission shaft 9 away from the transmission bevel gear 15. One end of the sliding column 19 is fixedly connected to the movable block 20.

[0021] The bottom outer side of the adjusting shaft 12 is provided with a locking thread 16, and an anti-loosening nut 17 is installed on the outer thread of the locking thread 16. The top of the anti-loosening nut 17 contacts the bottom of the strip housing 11. During use, the locking thread 16 and the anti-loosening nut 17 interact to position the adjusting shaft 12, thereby ensuring that the adjusting positioning component 6 can easily achieve a more stable positioning effect when connecting the wires.

[0022] Working Principle: During operation, the mounting plate 1 is first fixed inside the distribution cabinet using mounting bolts that match the diameter of the mounting hole 2, thus achieving a fixed installation of the entire device. Then, during wiring, the cables to be connected are inserted into the wiring slots 4 respectively. The anti-loosening nut 17 is then loosened to release the positioning of the adjusting shaft 12. The adjusting block 13 is then rotated, causing the adjusting shaft 12 to rotate. The adjusting shaft 12 drives the drive bevel gear 14 to rotate, which in turn drives the transmission bevel gear 15 to rotate. The transmission bevel gear 15 then drives the transmission shaft 9 to rotate. The movable block 20 moves, causing the sliding column 19 to slide inside the arc-shaped groove 18. At the same time, the transmission shaft 9 drives the adjusting positioning block 10 to move. One end of the adjusting positioning block 10 moves through the arc-shaped groove 5 to the inside of the wiring groove 4, positioning the cable inside the wiring groove 4. Then, the rotation of the adjusting block 13 stops, and the anti-loosening nut 17 is tightened to reposition the adjusting shaft 12. This allows the arc fault self-healing device of the distribution box to quickly perform wiring operations on multiple fault arc protectors during use, improving work efficiency and thus facilitating better practicality.
