First positioning bolts 15 are provided at the center of both sides of the protective frame 7. A hinge 5 is provided on one side of the front end of the housing 1, and a door 14 is provided on the middle surface of the front end of the housing 1. A sealing baffle 4 is provided on the front surface of the door 14. The other side of the front end of the housing 1... A locking groove 8 is provided on the middle side surface, and a connecting groove 9 is provided on the upper surface of the locking groove 8. A connecting groove 13 is provided on the middle side surface of the sealing baffle 4. A handle 12 is provided inside the connecting groove 13. A connecting shaft 10 is provided at the inner end of the handle 12. A locking block 11 is provided on the outer side surface of the connecting shaft 10. A protective plate 2 is provided on the rear side surface of the housing 1. Second positioning bolts 24 are provided on the inside of the housing 1 and the protective plate 2. Positioning strips 20 are provided on both sides of the terminal block body 19. A first slot 21, a second slot 22 and a third slot 23 are respectively provided on the upper sides of the inside of the housing 1.

[0025] The base 3 is fixedly connected to the bottom of the housing 1. The first misalignment groove 16, the second misalignment groove 17, and the third misalignment groove 18 are respectively fitted and connected to the surface of the base 3. The base 3 provides heat dissipation space for the interior of the dustproof and waterproof terminal box, preventing the temperature inside the terminal box from rising too high during long-term closed or semi-closed operation. The protective frame 7 is fixedly connected to the outer surface of the top cover 6, and the top cover 6 is supported and connected to the top surface of the housing 1. The protective frame 7 forms a sealed contact with the upper edge of the housing 1. The protective frame 7 is fixedly connected to the upper edge of the housing 1 by the first positioning bolt 15 and the thread on the upper part of the housing 1, forming a sealed contact. The protective frame 7 provides dustproof and waterproof protection for the upper part of the housing 1, preventing dust and moisture from entering. The terminal box is accessed from the top of housing 1. Hinges 5 are fixedly connected to one side of the front end of housing 1. One side of the door 14 is fixedly connected to one side of hinge 5. The door 14 is hinged to the front end of housing 1 via hinge 5. The hinge 5 allows the door 14 to be positioned and opened / closed relative to the front end of housing 1. A sealing baffle 4 is fixedly connected to the front surface of door 14. The sealing baffle 4 is locked and sealed to the front surface of housing 1 via door 14 and hinge 5. The sealing baffle 4 provides a sealed contact between the top and bottom of housing 1, preventing dust and water accumulation inside the terminal box due to gaps at the top and bottom of housing 1. A locking groove 8 is recessed and fitted into the middle surface of the other side of the front end of housing 1. The upper surface of the connecting groove 8 is fitted and connected to the connecting groove 13, which is fitted and connected to the middle surface of one side of the sealing baffle 4. The handle 12 is limited and rotated inside the connecting groove 13. The connecting shaft 10 is fixedly contacted with the inner end of the handle 12. The locking block 11 is fixedly contacted with the outer surface of the connecting shaft 10. The connecting shaft 10 is engaged and contacted inside the locking groove 8. The locking block 11 is engaged and slidably connected inside the connecting groove 9. Through the locking block 11 and the locking groove 8, the door 14 and the sealing baffle 4 can be kept fixed to the front of the housing 1. Through the handle 12, it can be rotated to one side and drive the connecting shaft 10 to rotate, so that the locking block 11 and the connecting groove 9 are in a horizontal state. Then, by directly pulling the handle 12, the door 14 can be opened to the outside. In the unfolded state, the connecting shaft 10 disengages from the locking groove 8. The protective plate 2 is fixedly connected to the rear surface of the housing 1. The second positioning bolt 24 is threadedly fixed to the wall through the inner perimeter of the housing 1 and the inner perimeter of the protective plate 2. The protective plate 2 prevents the housing 1 of the terminal box from directly contacting the wall, which could easily lead to damage to the housing 1 over time. It also provides contact space between the protective frame 7 and the wall. The terminal block 19 is fixedly connected to the positioning strips 20 on both sides. The first slot 21, the second slot 22, and the third slot 23 are all fitted and connected to the upper sides of the inner perimeter of the housing 1. The positioning strips 20 are all engaged and fixedly connected to the inner perimeter of the first slot 21, the second slot 22, and the third slot 23.The terminal block body 19 is fixedly supported and connected to the internal space of the housing 1 via positioning clips 20, a first slot 21, a second slot 22, and a third slot 23. These positioning clips allow the terminal block body 19 to be installed at different heights within the terminal box housing 1.

[0026] Working principle: During operation, the dustproof and waterproof terminal box allows the cable to pass through the first misalignment groove 16, the second misalignment groove 17, and the third misalignment groove 18 from bottom to top, passing through the inner side of the base 3 and connecting to the terminal blocks 19 at different positions inside the terminal box. The protective frame 7 and the sealing baffle 4 provide a sealing effect for the cable equipment inside the terminal box, preventing dust and moisture from entering the terminal box. At the same time, the second positioning bolt 24 makes the dustproof and waterproof terminal box vertical to the ground, placing the first misalignment groove 16, the second misalignment groove 17, and the third misalignment groove 18 at the bottom of the terminal box, preventing moisture from contacting the inside of the terminal box through the first misalignment groove 16, the second misalignment groove 17, and the third misalignment groove 18 and forming water accumulation. The vertical terminal box keeps the inside of the terminal box dry.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
