[0002] Cable is one of the main tools for power transmission. It is used to transmit and distribute high-power electric energy in the trunk lines of the power system. It is a common and indispensable tool in daily life. In the wiring and use of power cables, there are often many cable branches. In addition to pulling out additional branch cables at the node position, sometimes it is necessary to connect additional branches at a certain position of the cable itself. Therefore, a splitter is needed for branching operations. However, the current splitters are not suitable for cable branching operations extending to all directions in the shaft due to their fixed branching directions. In addition, the existing splitters can only connect branch lines of the same path. When the line needs to be adjusted or changed, the line needs to be dismantled and reconnected, which is more troublesome to operate. Moreover, the existing splitters can only be used for cables of one wire diameter, resulting in poor actual use effect. Therefore, it is very necessary to provide a cable branching device and a method of use with a reasonable structure, multi-directional branching connection, non-same path branching connection, and strong versatility.
