[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time.

[0003] There are two types of terminal blocks currently used in the market: the first option is to draw threaded holes on the copper bars of the circuit breaker inlet and outlet; the second option is to open a hexagonal slot on the base of the circuit breaker and put a nut in the hexagonal slot. However, both of these have low strength. In actual use, the threaded holes on the copper bars of the first option are easily damaged when subjected to large torque, which is not conducive to line connection; the base of the second option will break when subjected to large torque, exposing the electronic components inside the circuit breaker to the outside world, making the electronic components easily affected by the external environment and causing rust or short circuit.
