Background technique

Circuit breakers, also known as air switches, are commonly used power distribution safety protection devices for buildings and even houses. Through multiple circuit breakers connected in parallel, the lines entering the building or houses are distributed into multiple independent safety protection circuits. When a circuit breaker corresponds to When the line is short-circuited or overloaded, the circuit breaker of the line is disconnected to ensure the safety of electricity consumption.

Usually, the access terminals of multiple circuit breakers are electrically connected sequentially through short wires to realize conduction with the access lines. As shown in FIG. 1 , the circuit breaker 20 includes a control switch 201, a first access terminal 202 and a second The access end 203 , the first access end 202 and the second access end 203 are respectively provided with bolts 2021 , 2031 for locking the wires directly or through pressing pieces or the like. The three circuit breakers 20 are connected in parallel, and the power supply line 30 is usually a live wire, electrically connected to the first access terminal 202 of the circuit breaker 20 at the left end, and connected to the first access terminals 202 of the other two circuit breakers 20 through short wires 40 in turn. electrical connection. At the same time, there should also be another power supply line electrically connected to the second access end 203 of the circuit breaker 20 at the left end, the power supply line is usually a neutral line; 203 is electrically connected. This connection method is relatively complicated, and it needs to use too many or even crossed lines to connect the live wire and the neutral wire, which not only takes a lot of installation time, but also has certain safety hazards. The current at the access end of the circuit breaker connected to the power supply line (that is, the first circuit breaker) is the same as the current on the power supply line. Due to the large current, it is easy to cause damage to the power supply line and the access end, and even the current is too large. The insulating material at the access end is heated and melted, which is likely to cause electrical accidents.
