Description

Technical Field

[0001] The present application relates to the technical field of circuit breakers, and in particular to a wiring structure of a plug-in circuit breaker. Background Art

[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. Therefore, it is widely used in power distribution systems. With the rapid development of my country's power and communication technology, higher and higher requirements are put forward for the practicality, safety and reliability of circuit breaker terminal electrical equipment. The disassembly and installation workload of traditional circuit breakers is large. At present, there are many wiring structures of plug-in circuit breakers, such as the utility model patent with application number 202123152904.0. The wire is inserted into the slide groove of the base along the wiring hole, and the screw is tightened by inserting a screwdriver along the installation hole. The end of the screw drives the swing part to swing when moving forward, and then the swing part can drive the first conductive contact piece to slide along the slide groove toward the second conductive contact piece. The first conductive contact piece and the second conductive contact piece can cooperate with the clamping and fixing of the wire to form a conductive connection between the wire and the terminal block. This method can improve the positioning of the wire and the conductive effect; but the design is cumbersome, the wiring efficiency is low, and it is inconvenient to repair when a fault occurs.
