DETAILED DESCRIPTION

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings:

[0027] This utility model provides a cabinet with a compartmentalized layout, divided into a front compartment and a rear compartment. Both the front and rear compartments are further divided into upper and lower areas. The lower area of ​​the front compartment is equipped with several front compartment DC contactors 10, front compartment post-stage conductor assemblies 9 connected to the front compartment DC contactors 10, and front compartment pre-stage conductor assemblies 11. The lower area of ​​the rear compartment is equipped with several rear compartment DC contactors 19, rear compartment post-stage conductor assemblies 18 connected to the rear compartment DC contactors 19, and rear compartment pre-stage conductor assemblies 20.

[0028] In one specific embodiment, the front compartment DC contactor 10 is connected to the positive output of the main unit cabinet A via the front compartment pre-stage conductor assembly 11, and to the positive output of the adjacent main unit cabinet B via the front compartment rear-stage conductor assembly 9. The rear compartment DC contactor 19 is connected to the negative output of the main unit cabinet A via the rear compartment pre-stage conductor assembly 20, and to the negative output of the adjacent main unit cabinet B via the rear compartment rear-stage conductor assembly 18. Multiple main unit cabinets can be connected in series into a system via the DC contactors and their connected conductor assemblies in the front and rear compartments. When higher power output is required, it is not necessary to design a separate cabinet with higher power and larger volume; instead, the demand can be met by increasing the number of cabinets connected in series, thereby increasing the overall system output power. Since each cabinet can be connected to other cabinets, resources can be flexibly allocated according to actual needs. This avoids the problem of insufficient resource utilization in traditional single-cabinet designs, improving resource utilization. This design makes the system highly scalable. When increased output power is required, new cabinets can be added and connected to the existing system. Furthermore, the compartmentalized layout within each cabinet simplifies maintenance and upgrades. Connecting multiple cabinets to meet power requirements avoids the need for a single, larger rack, thus reducing manufacturing costs and space requirements. This is particularly important for applications with limited space or tight budgets.

[0029] See Figure 1 , 2 and Figure 3 As shown, this utility model provides a rack cabinet with a front and rear compartment layout. Circuit boards and components are distributed in different areas, and multiple DC contactors are arranged in both the front and rear compartments. Input and output are achieved through front and rear conductive components, effectively reducing heat exchange during rack operation and extending component lifespan. Furthermore, the rear door panel features upper and lower louvers with dustproof cotton components inside. Natural heat dissipation is used, reducing overall cost. In addition, this rack structure layout satisfies both ease of use and improved assembly efficiency, effectively reducing the cost of the rack cabinet and minimizing heat generated during component operation.

[0030] The aforementioned rack cabinet, on the one hand, reduces the number of components and optimizes the structural design to lower the cost of the rack without affecting its performance. On the other hand, the compartmentalized layout distributes the circuit board components and electrical components in different areas, and multiple DC contactors are arranged in both the front and rear compartments for input and output through the front and rear conductive components. This assembly method not only facilitates wiring for customers, but also results in an aesthetically pleasing component layout and facilitates heat dissipation. This rack cabinet component layout satisfies user convenience, improves assembly efficiency, and enhances the user experience.

[0031] The aforementioned cabinet features a compartmentalized layout for components, divided into front and rear compartments. The system allows for assembly, debugging, and maintenance by opening the front and rear doors. Each compartment is equipped with five DC contactors, providing input and output via front and rear conductor components, facilitating client wiring. The overall layout is neat and aesthetically pleasing. Furthermore, it effectively reduces heat exchange during cabinet operation, extending the lifespan of the components.

[0032] The cabinet uses AC220V power supply. The AC input devices include miniature circuit breakers 5 and auxiliary power supplies 6. The cabinet and the host equipment exchange data via CAN communication. Both use terminal blocks for cable entry and are located at the bottom of the left side wall of the cabinet. The power supply and CAN lines are routed separately via cable tie bridges. This layout reduces interference between cables, facilitates on-site wiring for customers, and optimizes the overall cost.

[0033] The DC contactor inlet adopts bottom-in and top-out or top-in and bottom-out, which reduces the length of the conductor and saves layout space. Five DC contactors are arranged in the front and rear compartments, which are connected to the two main cabinets respectively, so that the cable distribution is even and neat, the space utilization of the whole machine is higher, the structure is more compact, and the assembly, debugging and maintenance are more convenient.

[0034] The cabinet has ventilation louvers arranged above and below the rear door component 12 to dissipate heat from the components inside the cabinet through natural heat dissipation. Dustproof cotton components are installed inside the louvers. The dustproof cotton is directly installed inside the U-shaped sheet metal of the cabinet door, which makes the installation of dustproof cotton simple, improves the protection level of the whole machine, and the dustproof cotton is inexpensive, reducing the cost of the whole machine.

[0035] In one embodiment, the upper region of the front compartment and the upper region of the rear compartment are symmetrical, the lower region of the front compartment and the lower region of the rear compartment are symmetrical, and the plurality of DC contactors and front and rear conductor assemblies arranged in the lower region of the front compartment are symmetrical with the plurality of DC contactors and front and rear conductor assemblies arranged in the lower region of the rear compartment.

[0036] In one embodiment, an AC input device is located in the upper area of ​​the front compartment, and an insulation monitoring board assembly 15 and an I / O board assembly 16 are arranged vertically in the upper area of ​​the rear compartment. A terminal block and a cabinet grounding copper busbar assembly 23 are located at the bottom of the left side wall of the cabinet. The key components, such as the AC input device, insulation monitoring board assembly 15, and I / O board assembly 16, are respectively arranged in the upper areas of the front and rear compartments, making the functional zoning within the cabinet more clearly defined. Simultaneously, the heat generated by the auxiliary power source 6 in the front compartment and the insulation monitoring board assembly 15 and I / O board assembly 16 in the rear compartment can be dissipated through the heat dissipation structure at the rear of the cabinet, thereby optimizing the overall heat dissipation effect.

[0037] In one embodiment, the AC input device includes a miniature circuit breaker 5 and an auxiliary power source 6. The miniature circuit breaker 5 is disposed on the upper side of the upper region of the front compartment, and the auxiliary power source 6 is disposed in the middle of the upper region of the front compartment.

[0038] In one embodiment, the terminal block includes a terminal power supply terminal block 21 and a terminal CAN communication terminal block 22, which are adjacent to each other on one side of the left side wall. The power supply line connected to the terminal power supply terminal block 21 and the CAN line connected to the terminal CAN communication terminal block 22 are routed separately by a cable tie and arranged at the bottom of the left side wall of the cabinet. Separating the power supply and CAN lines by the cable tie reduces interference between cables and facilitates on-site wiring for customers.

[0039] In one embodiment, a front door assembly 1 is provided at the front opening of the front compartment, and a fault indicator light 2, a running indicator light 3 and a power indicator light 4 are arranged sequentially on the upper part of the front door assembly 1.

[0040] In one embodiment, a rear door assembly 12 is provided at the rear opening of the rear compartment. The upper and lower parts of the rear door assembly 12 are respectively provided with upper and lower ventilation louvers. At corresponding positions on the inner side of the rear door assembly 12, an upper rear door dustproof cotton assembly 13 and a lower rear door dustproof cotton assembly 14 are respectively provided. The ventilation louvers arranged at the top and bottom of the rear door assembly 12 utilize natural heat dissipation to cool the components inside the cabinet, eliminating the need for additional cooling equipment and reducing the overall cost. Simultaneously, the dustproof cotton assemblies installed inside the louvers provide both dust protection and ventilation, improving the overall protection level of the machine. The upper rear door dustproof cotton assembly 13 and the lower rear door dustproof cotton assembly 14 are installed inside the U-shaped sheet metal of the rear door assembly 12.
