[0002] A circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions and can close, carry, and break the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their application scope. The boundary between high and low voltages is relatively blurred. Generally, those above 3 kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power supply lines and motors, etc. When they have serious overload, short circuit, and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of a fuse switch and an over- and under-thermal relay, etc. Moreover, generally no parts need to be changed after breaking the fault current. It has been widely used. In the generation, transmission, and use of electricity, power distribution is an extremely important link.

[0003] When wiring a circuit breaker, most of the time, a screwdriver is used manually to tighten the screws, and then the wires of the circuit are fixed on the wiring board of the circuit breaker. Moreover, there are many connectors on the surface of the circuit breaker, and each of them needs to be fixed separately by a screwdriver, which is time-consuming and laborious. In the process of screw connection, not only the operation is cumbersome and complex, but also it further leads to time-consuming and laborious.

A slide groove 7 is formed in the inner side of the roller 3 on the side. A card slot 6 is formed in the inner side of one end of the roller 3. One end of the wiring is inserted into the inner side of the card slot 6. The end of the wiring is limited and fixed through the card slot 6. Then the roller 3 is rotated. The roller 3 drives the wiring to rotate together. And under the mutual cooperation of the clamping block 4 and the roller 3, the clamping block 4 realizes the clamping and fixing of the wiring. And through the connecting shaft 10, multiple rollers 3 can be rotated simultaneously, so that the clamping and fixing of multiple wirings can be realized at one time, facilitating the work of the staff and improving the overall work efficiency.

[0024] As a further improvement of the present utility model, as Figure 1 、 Figure 2 and Figure 3 shown, one end of the circuit breaker body 1 is screwed with a screw 8. One end of the screw 8 is fixedly connected with a slide block 11. The slide block 11 is slidably connected with the corresponding roller 3 through the slide groove 7. The slide block 11 is polygonally arranged to ensure that the slide block 11 can drive the roller 3 to rotate. By rotating the screw 8, the slide block 11 can be rotated. Then the slide block 11 drives the roller 3 to rotate relative to the conductive ring 2.

Under the action of the connecting shaft 10, multiple rollers 3 can rotate together.

[0028] Working process: When wiring the circuit breaker main body 1, one end of the wiring is inserted into the inner side of the card slot 6, and the end of the wiring is limited and fixed through the card slot 6. Then, the turntable 9 drives the screw rod 8 to rotate spirally inside one end of the circuit breaker main body 1. At the same time, the screw rod 8 also drives the slider 11 to rotate together. Then, the slider 11 drives the roller 3 to rotate, and the roller 3 drives the wiring to rotate. And under the mutual cooperation of the clamping block 4 and the roller 3, the clamping block 4 realizes the clamping and fixing of the wiring. And through the connecting shaft 10, multiple rollers 3 can rotate simultaneously, so that the clamping and fixing of multiple wirings can be realized at one time, facilitating the work of the staff, improving the overall work efficiency. At the same time, the screw rod 8 also drives the slider 11 to slide relative to the roller 3 through the chute 7.
