[0018] As attached Figure 1 -Attached Figure 4 As shown, a cable branch box comprises a box body 1, which is divided into an upper cavity and a lower cavity. A trapezoidal opening is provided at the front end of the upper cavity and a trapezoidal door 2 is hinged at the trapezoidal opening. A mounting plate 3 is provided in the upper cavity, and three mounting holes are provided on the mounting plate 3. Bidirectional bushings 4 are inserted into the three mounting holes. A live indicator 5 and a grounding terminal 6 are provided on one side of the upper cavity. Lead wires 7 of the three bidirectional bushings 4 are bound as a whole through a winding tube 8 and connected to a connecting wire 9 of the live indicator 5, and a grounding wire 10 of the live indicator 5 is connected to the grounding terminal 6. A wire outlet hole 11 corresponding to the position of the bidirectional bushing 4 is provided at the bottom of the lower cavity of the box body 1.

[0019] In one embodiment, both sides of the upper cavity of the box body 1 are hinged with gas rods 12, and the output ends of the gas rods 12 on both sides are respectively hinged with the two sides of the trapezoidal door 2. In this embodiment, both sides of the upper cavity of the box body 1 are hinged with gas rods 12, and the output ends of the gas rods 12 are respectively hinged with the two sides of the trapezoidal door 2. This design makes the opening and closing of the trapezoidal door 2 more convenient. The operator only needs to gently push the door, and the gas rod 12 can automatically complete the opening and closing of the door body. This not only reduces the labor intensity of the operator, but also improves work efficiency. At the same time, the buffering effect of the gas rod 12 can also effectively prevent the noise and damage caused by the violent closing of the door.

[0020] In one embodiment, a gusset plate 13 is provided at the bottom end of the trapezoidal door 2, a locking groove 14 corresponding to the position of the gusset plate 13 is provided at the lower front side of the box body 1, a locking tongue 15 is provided on the locking groove 14, a locking hole corresponding to the locking tongue 15 is provided on the gusset plate 13, and the locking tongue 15 and the locking hole are locked by a lock 16. In this embodiment, a gusset plate 13 is provided at the bottom end of the trapezoidal door 2, a locking groove 14 corresponding to the position of the gusset plate 13 is provided at the lower front side of the box body 1. A locking tongue 15 is provided on the locking groove 14, and a locking hole corresponding to the locking tongue 15 is provided on the gusset plate 13. The locking tongue 15 is locked with the locking hole by the lock 16, so that the box door is firmly closed. This locking mechanism has a simple structure and is easy to operate, and can effectively prevent unauthorized personnel from opening the box door, thereby ensuring the safety of the cable branch box.

[0021] In one embodiment, reinforcing ribs 17 are provided on both sides of the upper cavity of the box body 1, and a plurality of fixing holes 18 are provided on the reinforcing ribs 17 on one side, and the winding tube 8 is fixed to the reinforcing ribs 17 by passing through the fixing holes 18 with a cable tie. In this embodiment, reinforcing ribs 17 are provided on both sides of the upper cavity of the box body 1 to enhance the structural strength of the box body. A plurality of fixing holes 18 are provided on the reinforcing ribs 17 on one side, and the winding tube 8 is fixed to the reinforcing ribs 17 by passing through the fixing holes 18 with a cable tie. This design not only allows the winding tube 8 to be firmly fixed to prevent the cable from loosening and falling off, but also optimizes the wiring structure, making the interior of the cable branch box more tidy and beautiful.

[0022] In one embodiment, the lower cavity of the box body 1 is provided with a reinforcing crossbeam 19, and a clamp 20 corresponding to the outlet hole 11 is fixed to the reinforcing crossbeam 19 by screws. This design enhances the fixing and supporting performance of the outlet hole, preventing the cable from loosening or falling off at the outlet hole. At the same time, the use of the clamp 20 also facilitates the fixing and replacement of the cable.

[0023] In one embodiment, heat dissipation holes are arranged around the bottom of the box 1, and a rain cover 21 is arranged on the heat dissipation hole, and a dust net 22 is arranged at the lower end of the rain cover 21. This design not only ensures good heat dissipation performance of the box, but also effectively prevents rainwater and dust from entering the box, ensuring the normal operation of the cable branch box. At the same time, the provision of the dust net 22 also extends the service life of the box.

[0024] In one embodiment, a support frame 23 is provided at the bottom of the box body 1. The design of the support frame 23 enables the cable branch box to be stably placed on the ground, thereby improving its stability in use.

[0025] Working principle: When using the cable branch box of the present application, first open the trapezoidal box door 2, and connect the cable that needs to be branched and connected into the upper cavity through the bidirectional bushing 4. The design of the bidirectional bushing 4 makes the access and lead-out of the cable more flexible and convenient. Subsequently, the lead-out line 7 of the bidirectional bushing 4 is bound as a whole through the winding tube 8, and connected to the connecting line 9 of the live display 5. In this way, the live display 5 can monitor the live state of the cable in real time and feed back the information to the operator. At the same time, the grounding wire 10 of the live display 5 is connected to the grounding terminal 6 to ensure the grounding protection of the cable. At the bottom of the lower cavity of the cable branch box, there is a wire outlet hole 11 corresponding to the position of the bidirectional bushing 4, and the cable is led out through the wire outlet hole 11 to realize the branch connection of the cable. In addition, the cable branch box of the present application also has a variety of safety and convenience designs. For example, the automatic opening and closing of the trapezoidal box door 2 is realized by the gas rod 12, which improves the convenience of operation. The design of the buckle plate 13 and the locking groove 14 enhances the sealing and safety of the box. The provision of the reinforcing rib plate 17 and the fixing hole 18 enables the winding tube 8 to be firmly fixed, preventing the cable from loosening and falling off. The design of the reinforced crossbeam 19 and the clamp 20 of the lower cavity enhances the fixation and support of the cable. The heat dissipation holes, rain cover 21 and dust net 22 at the bottom of the box ensure good heat dissipation and protection performance of the box. The provision of the support frame 23 enables the cable branch box to be firmly placed on the ground, improving its stability in use.
