[0031] In one aspect of the embodiment of the present application, please refer to Figure 1 , Figure 2 As shown, a multi-pole wiring module 100 is provided, including a shell 10, in which a plurality of chambers arranged side by side are formed, each chamber is used to set a busbar 100A to be connected to a pole circuit breaker 201, and to set a terminal 103 to be connected to a busbar, and the busbar 100A of the same pole is connected to the terminal 103.

[0032] The housing 10 is divided into a plurality of chambers, and the plurality of chambers are arranged side by side. Figure 2 As shown, each chamber is provided with a busbar 100A and a terminal 103, the busbar 100A is connected to the circuit breaker 201, and the terminal 103 is connected to the busbar; multiple chambers are provided with multiple busbars 100A and multiple terminal 103, and a multi-pole circuit breaker 201 and a busbar can be connected.

[0033] Therefore, the multi-pole wiring module 100 provided in the embodiment of the present application has a plurality of chambers arranged side by side in its housing 10, each of which is provided with a busbar 100A for connecting to a single-pole circuit breaker 201 and a wiring terminal 103 for connecting to a busbar, and the connection with the multi-pole circuit breaker 201 and the busbar can be completed through the multi-pole wiring module 100. Through the modular setting of the multi-pole wiring module 100, the multi-pole wiring module 100 and the multi-pole circuit breaker 201 can be freely disassembled and assembled, the scalability is enhanced, the functional structure is comprehensive, and flexible matching is convenient.

[0034] For example, Figure 1 The middle shell 10 includes a side cover 14 and a multi-pole shell group connected to the side cover 14 . The multi-pole shell group includes a bottom cover 11 , an upper cover 13 and a plurality of middle covers 12 located between the bottom cover 11 and the upper cover 13 . Two chambers are formed on both sides of the middle cover 12 .

[0035] The multi-pole wiring module 100 of the present application is formed into an L-shaped structure as a whole. A side cover 14 is arranged above the multi-pole wiring module 100 . The side cover 14 is used to arrange common components of the multi-pole wiring module 100 , such as a leakage sensor 106 .

[0036] The side cover 14 is located above the multi-pole shell assembly and can be riveted to the multi-pole shell assembly; for example Figure 1 In the embodiment, the side cover 14 and the multi-electrode shell group are riveted together by rivets 14a.

[0037] In other embodiments, the side cover 14 and the multi-pole housing group may also be connected by screws / nuts; or, the side cover 14 and the multi-pole housing group below are snap-fitted; for example, a buckle is provided on the side cover 14, and a slot is provided on the multi-pole housing group, and the side cover 14 and the multi-pole housing group are snap-fitted by the cooperation of the buckle and the slot.

[0038] The multi-pole housing group as a whole includes a bottom cover 11 and an upper cover 13. A plurality of middle covers 12 are arranged between the bottom cover 11 and the upper cover 13. Two chambers are formed on both sides of the middle cover 12. A busbar 100A and a terminal 103 are arranged in each chamber.

[0039] For example, when a middle cover 12 is provided, a chamber is formed between the two sides of the middle cover 12 and the bottom cover 11 and the upper cover 13 respectively. At this time, the multi-pole wiring module 100 is a two-pole wiring module with two busbars 100A and two wiring terminals 103, which can connect the two-pole circuit breaker 201 and the busbar.

[0040] For another example, when two middle covers 12 are provided, a chamber is formed between one middle cover 12 and the bottom cover 11, a chamber is formed between the other middle cover 12 and the upper cover 13, and a chamber is formed between the two middle covers 12, so a three-pole wiring module is formed, which can connect the three-pole circuit breaker 201 and the busbar. One busbar is provided, and all the above modules are installed on the same busbar.

[0041] The bottom cover 11, the middle covers 12 and the upper cover 13 are stacked in sequence, and the side cover 14 is connected to the multi-pole shell group in a direction perpendicular to the stacking direction.

[0042] When the bottom cover 11, the middle covers 12, and the upper cover 13 are stacked in sequence, the stacking direction is the width direction D of the multi-pole wiring module 100; the bottom cover 11, the middle cover 12, and the upper cover 13 can also be connected to each other by means of snaps or slots, or connected in other ways, such as riveting or screw / nut connection, etc., to facilitate assembly.

[0043] The side cover 14 is located above the multi-pole shell group and can be riveted, screwed / nut connected or clamped with the multi-pole shell group along the height direction H of the multi-pole wiring module 100.

[0053] The leakage current collected by the leakage sensor 106, the main circuit current collected by the main circuit detector 108, and the voltage collected by the circuit board can all be fed back to the signal sampling module 105, and then fed back to the main control module for processing.

[0059] For the same-pole busbar 100A, it includes at least an L-pole busbar 101, or at least an N-pole busbar 102, for example Figure 2 There is only one busbar 100A in the circuit, and the busbar 100A can be an L-pole busbar 101 or an N-pole busbar 102; when both the L-pole busbar 101 and the N-pole busbar 102 are present, the L-pole busbar 101 and the N-pole busbar 102 are arranged side by side, such as Figure 3 to Figure 5 shown.
