Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] One aspect of the embodiments of this application refers to... Figure 1 , Figure 2 A switching module is provided, including a protective cover disposed on one side of a vertical busbar 11 along a first direction F1. A contact assembly 12 and a conductive busbar 14 are disposed inside the protective cover. The conductive busbar 14 extends out of the protective cover. The contact assembly 12 is plugged into and plugged into the protective cover along the first direction F1. The contact assembly 12 forms an electrical connection with the conductive busbar 14 and the vertical busbar 11.

[0040] like Figure 2 As shown, perpendicular to Figure 2 The paper orientation is the first direction F1. A mounting plate 16 is provided in front of the vertical busbar 11 along the first direction F1. The mounting plate 16 is provided with a mounting port. The protective cover includes a first protective cover 15, which is disposed in and fixed in the mounting port. The contact assembly 12 is disposed inside the first protective cover 15. The contact assembly 12 is inserted and removed along the first direction F1 toward the vertical busbar 11. The protective cover can isolate the contact assembly 12 and the vertical busbar 11. When the contact assembly 12 needs to be replaced, it is removed from the protective cover. Since the vertical busbar 11 is isolated by the protective cover, it can meet the IP20 protection requirement. There is no need to disconnect the power, which can meet the normal operation requirements of the equipment.

[0041] One end of the conductive busbar 14 is inserted into the protective cover for electrical connection with the contact assembly 12, and the other end extends out of the protective cover for external connection of the outgoing cable. For example, the conductive busbar 14 is generally a copper busbar, but it can also be a copper-aluminum composite busbar, etc., as long as it is made of a conductive material.

[0042] Among them, reference Figures 3-5 As shown, the contact assembly 12 includes a front housing 122 and a rear housing 123 disposed opposite to each other. A bridge-type contact 121 is disposed between the front housing 122 and the rear housing 123. One end of the bridge-type contact 121 extends out of the rear housing 123. The end of the bridge-type contact 121 extending out of the rear housing 123 has an electrical connection portion 121a. The bridge-type contact 121 is electrically connected to the vertical busbar 11 and the conductive busbar 14 through the electrical connection portion 121a.

[0043] like Figures 6-10As shown, the front housing 122 forms a structure with an inner cavity. One end of the bridge-type contact 121 is placed in the inner cavity of the front housing 122 and is installed by fitting the inner cavity of the front housing 122 through the assembly part 121b of the bridge-type contact 121. Then, the rear housing 123 is installed to fix the bridge-type contact 121. The rear housing 123 is an open frame structure, so that the other end of the bridge-type contact 121 extends out of the rear housing 123 along the first direction F1. The end of the bridge-type contact 121 extending out of the rear housing 123 forms an electrical connection part 121a. The bridge-type contact 121 forms an electrical connection with the vertical busbar 11 and the conductive busbar 14 through its electrical connection part 121a.

[0044] When the front cover 122 and the rear cover 123 are installed, they are connected by a snap-fit ​​mechanism to facilitate disassembly and assembly. For example, the front cover 122 is provided with a first slot 122a, and the rear cover 123 is provided with a first buckle 123a. The front cover 122 and the rear cover 123 are snap-fitted together by the cooperation of the first buckle 123a and the first slot 122a.

[0045] like Figure 11 , Figure 12 As shown, the protective cover includes a first protective cover 15, in which a plurality of protective holes 154 are formed. The electrical connection portion 121a of the bridge-type contact 121 of the contact assembly 12 extends through the protective holes 154 toward the vertical busbar 11.

[0046] The first protective cover 15 has an internally recessed structure to form a cavity within the first protective cover 15. A cover wall 151 is formed at the cavity opening for connection with the mounting plate 16. A plurality of protective holes 154 are formed within the cavity, each protective hole 154 penetrating the cavity wall of the first protective cover 15. Two protective holes 154 arranged side by side along the second direction F2 are used to allow the two electrical connection portions 121a of a bridge-type contact 121 to pass through.

[0047] In the embodiments of this application, the front shell 122 can accommodate multiple bridge-type contacts 121 arranged side by side along the third direction F3. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other, which allows a first protective cover 15 to install multiple bridge-type contacts 121, and a mounting plate 16 to set multiple contact assemblies 12. By increasing or decreasing the number of contact assemblies 12 and bridge-type contacts 121, flexible switching between large current and small current can be achieved, making the unit height of large current and small current consistent, which is convenient for modification.

[0048] When the contact assembly 12 and the first protective cover 15 are installed together, a second buckle 122b is provided on the front shell 122 of the contact assembly 12, and a second slot 153 is provided on the first protective cover 15. The contact assembly 12 is snapped into the first protective cover 15 by the cooperation of the second buckle 122b and the second slot 153.

[0049] In addition, a reinforcing rib 152 is formed on the outer wall of the first protective cover 15. The reinforcing rib 152 can play a limiting role. The reinforcing rib 152 cooperates with the cover wall 151 to lock the first protective cover 15 onto the mounting plate 16, and also to improve the structural strength of the first protective cover 15.

[0050] The protective shield also includes a second protective shield 13, such as Figure 8 , Figure 9 As shown, the second protective cover 13 is disposed opposite to the first protective cover 15 along the first direction F1, and the second protective cover 13 is close to the vertical busbar 11, and the conductive busbar 14 is disposed inside the second protective cover 13.

[0051] The first protective cover 15 and the second protective cover 13 are disposed opposite each other on both sides of the mounting plate 16 along the first direction F1.

[0052] Specifically, a third slot 132 is formed on the second protective cover 13, one end of the conductive busbar 14 is inserted into the third slot 132 for fixation, and the other end extends outward from the second protective cover 13.

[0053] The groove wall of the third slot 132 forms a mounting hole 131, correspondingly, such as Figure 10 As shown, a through hole 141 is formed on the conductive bus 14. The two are fixed with bolts and nuts so that one end of the conductive bus 14 is fixed in the slot of the second protective cover 13, and the other end extends outward through the second protective cover 13. The end of the conductive bus 14 located outside the second protective cover 13 is used to connect with the outgoing cable.

[0054] An isolator 133 is formed inside the second protective cover 13, dividing the inner cavity of the second protective cover 13 into multiple protective cavities. The electrical connection portion 121a of the bridge-type contact 121 of the contact assembly 12 extends toward the inner cavity of the second protective cover 13 and corresponds to the protective cavity. At the same time, the isolator 133 also serves as a support to enhance the structural strength of the second protective cover 13.

[0055] The bridge-type contact 121 of the contact assembly 12 has two electrical connection portions 121a. The electrical connection portions 121a extend along the first direction F1 through the protective hole 154 of the first protective cover 15 toward the second protective cover 13. The electrical connection portions 121a correspond one-to-one with the protective hole 154 and the protective cavity.

[0056] On the other hand, this application also discloses a switch cabinet, including a cabinet body, a vertical busbar 11 disposed in the cabinet body, and a transfer module as described above.

[0057] A circuit breaker may also be installed inside the switch cabinet. The mounting plate 16 is located on the side of the vertical busbar 11 near the circuit breaker. The mounting plate 16 is fixed inside the switch cabinet with screws. The end of the conductive busbar 14 extending out of the second protective cover 13 is also fixed inside the switch cabinet.

[0058] The electrical connection of the circuit breaker, vertical busbar 11, conductor busbar 14, and outgoing cables in the switch cabinet is achieved through the adapter module.

[0059] Due to the structural design of the transfer module, the switch cabinet of this application can be used in small-sized scenarios, resulting in a smaller cabinet width. Compared with the conventional cabinet width of 600mm, the cabinet width of this application can be reduced to 400mm, occupying less space.

[0060] This circuit breaker incorporates the same structure and beneficial effects as the transfer module in the foregoing embodiments. The structure and beneficial effects of the transfer module have been described in detail in the foregoing embodiments and will not be repeated here.

[0061] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
