[0027] Example:

[0028] like Figure 1-6 As shown, in this embodiment, the charging pile host includes: a cabinet 1, a mounting frame 2, a circuit breaker 3, an AC contactor 4, and a DC charging pile 5; the mounting frame 2 is fixed inside the cabinet 1, the DC charging pile 5 is installed at one end of the mounting frame 2, the circuit breaker 3 and the AC contactor 4 are fixed at the other end of the mounting frame 2, and the circuit breaker 3 and the AC contactor 4 are respectively arranged on opposite sides inside the cabinet 1; the output end of the AC contactor 4 is connected to the input end of the DC charging pile 5 through a first copper busbar assembly, and the input end of the AC contactor 4 is connected to the output end of the circuit breaker 3 through a second copper busbar assembly, and the first copper busbar assembly and the second copper busbar assembly are respectively fixed to the mounting frame 2 through insulating posts 9.

[0029] Specifically, the charging pile in this embodiment can be a DC charging pile, and its AC main circuit route during operation is: power supply to the distribution cabinet → molded case circuit breaker 3 → AC contactor 4 → DC charging pile 5. The circuit breaker 3 in this embodiment can be a molded case circuit breaker 3. In this embodiment, the circuit breaker 3, AC contactor 4, and DC charging pile 5 are all installed inside the cabinet 1 via the mounting bracket 2. The DC charging pile 5 is located at one end of the mounting bracket 2, for example, it can be installed at the upper or lower end of the cabinet 1. The circuit breaker 3 and AC contactor 4 are located at the other end of the mounting bracket 2. The AC components are placed on the same side, and the components are arranged from opposite sides of the cabinet 1. That is, the circuit breaker 3 and AC contactor 4 are respectively located on opposite sides of the mounting bracket 2 (e.g., the front and the rear). The connection between AC contactor 4 and DC charging pile 5, and between AC contactor 4 and circuit breaker 3 are respectively achieved by designing the first copper busbar assembly and the second copper busbar assembly. This facilitates the smooth connection of the AC input main circuit, shortens the wiring path between components, shortens the distance between AC contactor 4 and DC charging pile 5, facilitates quick wiring, saves assembly space, reduces cable costs, improves work efficiency, and enhances the aesthetics of the wiring.

[0030] In this embodiment, as Figure 3 and 4 As shown, the mounting frame 2 includes a frame body 21 and an assembly shell 22 installed at one end of the frame body 21. The assembly shell 22 has an assembly cavity 221 that matches the shape of the DC charging pile 5, and the DC charging pile is fixed within the assembly cavity 221. Specifically, the assembly shell 22 is provided to fix the DC charging pile 5, providing excellent positioning. The frame body 21 has a fixing frame that matches the assembly shell 22. During assembly, the DC charging pile 5 can be first inserted into the assembly shell 22, and then the assembly shell 22 and the DC charging pile 5 can be inserted into the frame body 21 as a whole. The assembly shell 22 and the frame body 21 can also be reinforced and fixed with screws, resulting in good fixing effect.

[0031] Furthermore, in this embodiment, as Figure 2 , 3 As shown in Figure 5, the first copper busbar assembly includes a plurality of first copper busbars 6 spaced apart. A clearance opening is provided on the assembly housing 22. One end of each first copper busbar 6 is connected to the corresponding interface of the output terminal of the AC contactor 4, and the other end passes through the clearance opening and is connected to the corresponding interface of the input terminal of the DC charging pile 5. Insulators 223 are provided between the wall of the clearance opening and the first copper busbar 6, and between adjacent first copper busbars 6.

[0032] Specifically, in this embodiment, the frame 21 can be a sheet metal support frame. The AC power supply interface of the DC charging pile 5 can be connected to the corresponding first copper busbar 6 via a cable. Each first copper busbar 6 can also be fixed to the frame 21 via an insulating post 9. In this embodiment, the copper busbar connecting the AC contactor 4 and the DC charging pile 5 can be extended into the charging pile compartment (i.e., the assembly shell 22), and the AC input cable of the DC charging pile 5 can be directly connected from the back of the charging pile to a copper busbar, realizing short-distance and fast wiring of the AC input of the charging pile. The area where the first copper busbar 6 passes through the clearance opening is isolated by an insulating component 223 to prevent mutual interference between lines. There can be multiple AC contactors 4, and multiple AC contactors 4 can be arranged side by side on the front side below the DC charging pile 5, which facilitates closing and opening operations and can also shorten the distance between the DC charging pile 5 and the AC contactor 4. It is understood that the number of first copper busbars 6 in this embodiment can be set according to the number of DC charging piles 5, the number of AC contactors 4, and the actual wiring requirements, and is not limited here. In some specific implementations, the insulating component 223 is an epoxy board, which has good insulation effect and can ensure the stability of signal transmission between the AC contactor 4 and the DC charging pile.

[0033] like Figure 4 As shown, in this embodiment, multiple DC charging piles 5 can be set according to different power requirements, for example, 20 DC charging piles 5 can be set; correspondingly, the assembly cavity 221 has multiple assembly positions corresponding to the number of DC charging piles 5, and guide plates 222 are set between adjacent assembly positions. Specifically, the assembly cavity 221 can be a cavity with one end open. The setting of the guide plate 222 can not only position two adjacent DC charging piles 5, but also play a guiding role in the assembly process. That is, during assembly, the DC charging pile 5 can be directly inserted into the assembly position. During the insertion process, the guide plate 222 can automatically prevent the DC charging pile 5 from shifting, and the assembly operation is simple.

[0034] Furthermore, in this embodiment, a fixing part 51 is also connected to the front side of the DC charging pile 5. The fixing part 51 extends circumferentially and is fixedly connected to the assembly shell 22 at the outlet of the assembly cavity 221 by screws. Specifically, the extension part, also known as the lug, can have multiple spaced-apart assembly holes. The outlet of the assembly cavity 221 of the assembly shell 22 is also provided with a corresponding extension part, and screw holes corresponding to each assembly hole can be provided on the extension part. Thus, the fixing part 51 and the extension part can be reinforced and fixed by screws to ensure the assembly stability between the assembly shell 22 and the DC charging pile 5.

[0035] In this embodiment, the mounting bracket 2 further includes a first mounting plate 23 and a second mounting plate 24 located on the bottom side of the assembly housing and respectively fixed to the bracket body 21. The AC contactor 4 is fixed to the side of the first mounting plate 23 away from the second mounting plate 24, and the circuit breaker 3 is fixed to the side of the second mounting plate 24 away from the first mounting plate 23. Specifically, one or more first mounting plates 23 and second mounting plates 24 can be provided according to actual needs, and there is no limitation here. Multiple screw holes can be opened on both the first mounting plate 23 and the second mounting plate 24. The AC contactor 4 can be installed on the first mounting plate 23 by screws, and the circuit breaker 3 can be installed on the second mounting plate 24 by screws, resulting in good assembly stability.

[0036] In this embodiment, as Figure 1 , 2 As shown in Figure 5, multiple AC contactors 4 are arranged side-by-side and fixed on one side of the first mounting plate 23; multiple circuit breakers 3 are arranged side-by-side and fixed on one side of the second mounting plate 24. The design is aesthetically pleasing, and the copper busbar connection is simple to operate. For example, four circuit breakers 3 can be arranged to form four independent inputs, fully supporting 800kW, and can be flexibly configured into modules with various power ratings. It is understood that in this embodiment, the number of AC contactors 4 and circuit breakers 3 can be set according to actual needs and are not limited here.

[0037] In this embodiment, the second copper busbar assembly includes a plurality of spaced second copper busbars 7; the second copper busbar 7 includes a first connecting section 71, a second connecting section 73, and an intermediate section 72 bent and connected between the first connecting section 71 and the second connecting section 73; the first connecting section 71 and the second connecting section 73 are respectively fixed to the frame 21 by insulating posts 9, the end of the first connecting section 71 away from the intermediate section 72 extends downward from the top of the circuit breaker 3 and is connected to the output terminal interface of the circuit breaker 3, and the end of the second connecting section 73 away from the intermediate section 72 extends upward from the bottom of the AC contactor 4 and is connected to the input terminal interface of the AC contactor 4. Specifically, through the design of the frame 21, the first mounting plate 23, and the second mounting plate 24, the devices are arranged on the front and rear sides, which can realize a reasonable arrangement between the circuit breaker 3 and the AC contactor 4, and improve the space utilization of the charging pile host. In this embodiment, the second copper busbar 7 is composed of a multi-segment bent connection structure, which is adapted to the frame 21 structure and the relative positions of the circuit breaker 3 and the AC contactor 4. That is, the AC contactor 4 is set at the bottom of the back of the cabinet 1, and the molded case circuit breaker 3 and the AC contactor 4 are connected through the second copper busbar 7, which facilitates the smooth connection of the AC input main circuit devices and achieves the effect of optimizing the connection path.

[0038] It is understood that in this embodiment, the DC charging pile 5 is disposed at the upper end of the frame 21, and the circuit breaker 3 and the AC contactor 4 are disposed at the lower end of the frame 21. In some other embodiments, the DC charging pile 5 may also be disposed at the lower end of the frame 21, and the circuit breaker 3 and the AC contactor 4 may be disposed at the upper end of the frame 21; no limitation is imposed here.

[0039] like Figure 1 and 6 As shown, in this embodiment, the charging pile host also includes an AC incoming copper busbar 8 connected to the circuit breaker 3.
