Technical Field
[0001] This utility model relates to the field of distribution box technology, and specifically to a sealing structure for a low-voltage distribution box. Background Technology
[0002] A distribution cabinet is the final stage equipment in a power distribution system. A distribution cabinet is a general term for motor control centers. It is a device used to distribute power. It distributes power from the main power source to different electrical equipment or circuits. It usually contains circuit breakers, terminals, protection devices and other control components.
[0003] Low-voltage distribution boxes are a type of distribution cabinet. Low-voltage distribution cabinets are rated for AC 50Hz, 380V power distribution systems used for power conversion and control in power, lighting, and distribution applications. Existing low-voltage distribution box sealing structures typically require pre-installation. After cables or wires have passed through the distribution box, it's impossible to seal the connection between the box and the cables. Using sealing putty or similar materials for sealing is prone to detachment. Therefore, a new sealing structure for low-voltage distribution boxes is proposed. The first and second sealing components are fitted over the outside of the cable and closed. The third and fourth sealing components are fitted over the outside of the cable inside the distribution box and closed. The closed first and second sealing components are connected to the second and third sealing components to the fourth sealing component via internal thread grooves and external thread teeth, thus sealing the connection between the distribution box and the cable.
