[0002] Cable distribution box is a device used to implement branching, branching, connection and circuit conversion of cable lines. The role of cable distribution is that there are multiple small cables on a relatively long line, which often leads to waste of cable use. Therefore, when the line is connected to the power load, a large trunk cable is often used for the line. Then, when approaching the load, a cable branch box is used to divide the trunk cable into several small cables, and the small cables are connected to the load. This wiring method is widely used in power supply for street lights and small users in urban power grids. The role of cable transfer is that on a relatively long line, the length of the cable cannot meet the requirements of the line, then a cable connector or cable transfer box must be used, which is usually used for short distances. Cable intermediate joints, but when the line is relatively long, according to experience, on cable lines above 1000m, if there are multiple intermediate joints in the cable, in order to ensure safety, cable branch boxes will be considered for transfer, and now cables of different cross-sections can be conveniently connected, the complicated process of cable intermediate joints is abandoned, the cable connection environment is improved, which is conducive to ensuring the connection quality and facilitating routine inspection and maintenance of subsequent operations.
