The circuit design of the multi-pole circuit breaker is simple, the wiring operation can be simplified, and the working reliability of the multi-pole circuit breaker is improved.

[0034] In this embodiment, the multi-pole circuit breaker includes a plurality of circuit breaker units 100, wherein the plurality of circuit breaker units 100 are arranged side by side along a first direction a. Figure 1 and Figure 3 To improve the integration of the multi-pole circuit breaker, the multiple circuit breaker units 100 can be connected to each other. For example, the housings 10 of two adjacent circuit breaker units 100 can be connected to each other through a mortise and tenon structure or a connector.

[0035] Each circuit breaker unit 100 includes a housing 10 and an operating mechanism 20, wherein the operating mechanism 20 is disposed in the housing 10. Any operating mechanism 20 can be driven to drive the corresponding circuit breaker unit 100 to open or close, and can simultaneously drive the operating mechanisms 20 of the remaining circuit breaker units 100 to operate through the linkage of the linkage member 200, thereby enabling all circuit breaker units 100 to be opened or closed at the same time.

[0036] It should be noted that the multiple circuit breaker units 100 are mutually linked through the linkage member 200. Specifically, the operating mechanisms 20 of the multiple circuit breaker units 100 are linked through the linkage member 200. In this way, the operating mechanism 20 of one circuit breaker unit 100 is driven to drive the circuit breaker unit 100 to open or close, and the operating mechanisms 20 of the remaining circuit breaker units 100 can act synchronously, so that the operating mechanisms 20 of the multiple circuit breaker units 100 are opened or closed at the same time, thereby enabling the multi-pole circuit breaker to be opened or closed.

In this way, when the circuit board 32 and the electric operating mechanism 31 are electrically connected, it is not necessary to open a hole for connecting the circuit board 32 and the electric operating mechanism 31 on the housing 10 of the circuit breaker unit 100. In this way, complicated perforation preparation and threading operation during wiring can be omitted, the wiring method is simple, and the preparation and assembly of the multi-pole circuit breaker are convenient.

The present application sets an electric assembly 30 in the housing 10 of at least two circuit breaker units 100 of the multi-pole circuit breaker, so that the electric assembly 30 having a circuit board 32 and an electric operating mechanism 31 is integrally set in the housing 10 of the corresponding circuit breaker unit 100. In this way, when the circuit board 32 and the electric operating mechanism 31 of each circuit breaker unit 100 are connected, it is only necessary to directly connect the wires in the housing 10 of the corresponding circuit breaker unit 100, without setting a perforation on the housing 10, and without performing a threading operation when connecting the wires. In this way, compared with the prior art in which one circuit board 32 corresponds to multiple electric operating mechanisms 31 (it is necessary to set corresponding perforations on the housing 10 of each circuit breaker unit 100, and then perform a threading operation when the circuit board 32 is connected to the multiple electric operating mechanisms 31), the circuit design of the present application is simple, which can simplify the wiring operation and improve the working reliability of the multi-pole circuit breaker.
