Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, protect power lines and motors, etc., and automatically cut off the circuit when they have serious overloads or short circuits and undervoltage faults. Its function is equivalent to the combination of fuse switches and over- and under-heat circuit breakers. Moreover, it is generally not necessary to change parts after breaking the fault current. At present, it has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity.

In addition, it is highly tool-dependent, and corresponding tools must be carried during installation and maintenance, otherwise it cannot be installed. Therefore, we propose a circuit breaker wiring structure component. Summary of the invention

[0031] like Figure 1-5 As shown, the utility model proposes a circuit breaker wiring structure assembly, including a circuit breaker body 1, a plurality of wire inlet holes 2 are opened on the body 1, a cavity connected to the wire inlet holes 2 is arranged in the body 1, a wiring terminal is installed in the wire inlet hole 2, and a plurality of wiring posts 5 are arranged on the body 1.

[0032] In this embodiment, a conductive seat 6 electrically connected to the terminal is fixedly installed in the cavity, a conductive column 17 is rotatably installed on the conductive seat 6, and a through hole 7 is opened on the conductive column 17. The through holes 7 are respectively connected to the wire entry holes 2. When the conductive column 17 rotates, the wire in the through hole 7 is wound around the surface of the conductive column 17 as the conductive column 17 rotates, thereby achieving a fixed connection between the wire and the circuit breaker. The structure is simple, not easy to fall off, and no tools are required, which is easy to install.

[0033] like Figure 1-4 As shown, a knob 3 is fixedly mounted on one end of the rotating rod 8 exposed outside the main body 1, and an anti-skid portion 13 is provided on the knob 3 for preventing slipping. By rotating the knob 3, the rotating rod 8 is rotated, thereby rotating the conductive column 17 fixedly connected to the rotating rod 8. A circular hole for the rotating rod 8 to pass through is provided at the bottom of the main body 1, and a limit assembly for limiting the rotation of the conductive column 17 is also fixedly mounted at the bottom of the main body 1.
