[0002] A circuit breaker is an electrical device used to disconnect the current in a circuit, usually for preventing circuit overload or short circuit. It is an important safety device in the power system, which can protect electrical equipment from damage and prevent dangers such as fires. The development of circuit breakers can be traced back to the end of the 19th century. Initially, it was designed to protect the safety of electrical equipment and personnel. With the development of electrical technology, circuit breakers have been continuously evolved and improved. Now they have become an indispensable part of modern power systems. However, the following problems exist in the existing circuit breakers:
[0003] When the existing circuit breaker is in use, the wiring slots on the circuit breaker often shake with the circuit breaker, resulting in the loosening of the wiring slots. When the wiring slots are loose, the operator needs to disassemble the circuit breaker and then re-arrange the wires. When the operator re-arranges the wires, the workload will increase due to the disorder of the wires inside the circuit breaker.
[0004] To solve the above problems, a circuit breaker for preventing a connector from loosening is proposed in this application. Content of the Utility Model
[0005] The utility model aims to provide a circuit breaker for preventing a connector from loosening, mainly for solving the problem that when the existing circuit breaker is in use, the wiring slots on the circuit breaker often shake with the circuit breaker, resulting in the loosening of the wiring slots. When the wiring slots are loose, the operator needs to disassemble the circuit breaker and then re-arrange the wires. When the operator re-arranges the wires, the workload will increase due to the disorder of the wires inside the circuit breaker.

[0013] Preferably, the thickness of the sliding groove is equal to that of the sliding rod, and the slider can be moved up or down by raising or lowering the sliding rod.
[0014] Preferably, the length of the slider is less than or equal to the length of the sliding window. If the slider is too long, it cannot be installed in the sliding window.
[0015] Preferably, the outer shell is made of plastic material, and the outer shell can play a role in dust prevention.
[0016] Preferably, the top of the buckle is provided with a downward bevel, and the buckle can be removed more conveniently with the bevel. Description of the drawings
