[0023] The technical solutions in the embodiments of the patent will be described clearly and completely below with reference to the drawings in the embodiments of the patent. Obviously, the described embodiments are only part of the embodiments of the patent, not all. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the patent.
[0024] When a certain construction site or small project needs temporary power, there is no safety protection through simple pull line power supply, which has serious safety hazards. The patent application proposes a low-voltage cable branch box, which is small in size, stable in operation, safe and reliable, easy to install, and has leakage protection function.
[0025] As Figures 1-5 , the metering low-voltage cable branch box includes a box body, which is rectangular in shape and is provided with front and rear cabinet doors 6 at the front and rear. The front cabinet door is divided into a front upper door 1 and a front lower door 2. The front upper door is provided with an organic glass observation window 4. Dustproof and waterproof sealing strips 5 are installed around the glass.
[0026] A lead seal lock 3 is also installed on the cabinet door. The bottom of the cabinet is closed by two insulating plates 7, and the top is a herringbone slope 8, which can enhance drainage and improve the protection strength of the box body. Louvers 9 are provided on the left and right sides of the box body for ventilation and heat dissipation.
[0027] As Figure 4 , the bottom of the box body is closed by two insulating plates 7 to prevent foreign matter from entering. The bottom plate is provided with a wire inlet hole, and a tower-shaped rubber ring 12 is installed on the wire inlet hole for better sealing effect and easy wire entry.
[0028] As Figure 5 , Figure 6 , the back door 6 of the box body is also provided with a waterproof door lock 11 and a lead seal lock 10. Opening the back door is an independent wire inlet terminal room 31, which is convenient for independent opening and operation. Figure 6 , Figure 11 , the back of the box body has an independent wire inlet room, which is convenient for wire inlet cable installation and is provided with a wire inlet copper bar 22, a metering transformer 23, a wire outlet busbar 24, and a wire outlet lap copper bar 25.
