The invention provides a circuit breaker, and relates to the technical field of electrical switching devices. Comprising a shell and a contact system installed in the shell. The plug-in and plug-out system is arranged in the shell and is connected with the contact system; the plug-in and plug-out system is connected with the plug-in and plug-out system; two conductive ends of an external conductive structure are both inserted into the plugging system, and one conductive end, the plugging system, the contact system and the other conductive end form a conductive loop. According to the invention, the plugging system is additionally arranged in the circuit breaker, external conductive structures such as copper bars and the like are plugged and matched with the plugging system, and the external conductive structures are directly plugged into the circuit breaker during assembly, so that the assembly steps are simplified, the assembly efficiency is improved, and subsequent disassembly and maintenance are facilitated.
Description
technical field [0001] The invention relates to the technical field of electrical switchgear, in particular to a circuit breaker. Background technique [0002] A circuit breaker is a switching device used to close, carry and break current under normal or abnormal circuit conditions. The circuit breaker needs to be connected with an external copper bar and other conductive structures to form a complete circuit. The existing circuit breaker and The connections between the copper bars are all connected by screws, which require cumbersome screwing in multiple places. This connection method is not conducive to the assembly of conductive structures such as copper bars, and it is also not conducive to disassembling the copper bars when the circuit breaker needs to be disassembled for maintenance. connection to other conductive structures. Contents of the invention [0003] The object of the present invention is to provide a circuit breaker to solve the problem of inconvenient as...
