[0002] A circuit breaker refers to a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect 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 scope of use. The boundary between high and low voltage is relatively vague, and those above 3kV are generally called high-voltage electrical appliances.

[0003] Most of the existing circuit breakers fix the wires on the wiring terminals by bolts, but such connection requires tools, such as screwdrivers, etc. The wires are inserted into the wiring holes of the wiring terminals and the bolts are turned by screwdrivers, so that the wires can be fixed on the wiring terminals of the circuit breaker. However, this method requires carrying corresponding tools every time wiring is done, which is very inconvenient. In addition, the use of screwdrivers to tighten the bolts slows down the installation and connection speed of the circuit breaker and the wires. Therefore, we propose a circuit breaker quick-connect structure to solve the above problems. Utility Model Content
