[0017] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a modular power distribution cabinet that facilitates wiring and maintenance. The cabinet includes a cabinet body 1, a front door 2 at the front end, a rear door 3 at the rear end, and ventilation holes 14 on both sides for heat dissipation. Several bases 4 are fixedly connected to the inner wall of the cabinet body 1. Several limiting frames 5 are fixedly connected to the upper and lower ends of each base 4. Functional modules 6 are slidably connected to the inner wall of each limiting frame 5. Female connectors 7 are fixedly connected to the rear end of each functional module 6. Several male connectors 8 are provided in the middle of each base 4. The female connectors 7 are slidably connected to the inner wall of the male connectors 8. Fixing blocks 9 are fixedly connected to both ends of each functional module 6. Hand-tightening bolts 10 are rotatably connected to the middle of each fixing block 9. Nuts 11 are threadedly connected to the rear end of each hand-tightening bolt 10 and are fixedly connected to the front side of the base 4.

[0019] Specifically, this distribution cabinet adopts a modular design concept, integrating key electrical components such as circuit breakers, contactors, and frequency converters into their respective independent functional modules 6. Each functional module 6 has a uniform external dimension, facilitating unified management and installation. Each functional module 6 precisely mates with the limiting frame 5 within the cabinet 1 via a sliding mechanism, ensuring that the female connector 7 at the rear of the functional module 6 accurately connects to the male connector 8 on the base 4. After insertion, the hand-tightened bolts 10 are tightened to create a threaded connection between the rear end of the module and the nut 11 at the front of the base 4, thus firmly securing the functional module 6. To prevent incorrect insertion, each functional module 6 is uniquely numbered corresponding to its position on the base 4, ensuring accurate matching. The base 4 is equipped with a power-off interlock switch, automatically cutting off power before the functional module 6 is removed. This modular structure eliminates the need for frequent disassembly and rewiring during maintenance or equipment replacement, shortening maintenance time and improving work efficiency.

[0020] Reference Figure 4 and Figure 5 The base 4 has several wiring grooves 12 fixedly connected to its rear side. The female connector 7 has a terminal block 13 fixedly connected to its rear end. The terminal block 13 passes through the wiring groove 12 and is used to connect cables. The lower end of the cabinet 1 has a cable inlet / outlet 15. The upper rear end of the cable inlet / outlet 15 has a fixed plate 16 fixedly connected to it. The lower end of the side wall of the cabinet 1 has a sliding groove 17. The inner wall of the sliding groove 17 has a movable plate 18 slidably connected to it. The front side of the fixed plate 16 and the rear side of the movable plate 18 are both fixedly connected to a sponge clip to wrap the cables. The upper end of the movable plate 18 has a spring pin 20. The bottom end of the cabinet 1 has a socket 19. The lower end of the spring pin 20 is slidably connected to the inner wall of the socket 19.

[0021] Specifically, the male connector 8 has a terminal block 13 connected to its rear end. The terminal block 13 passes through the wiring groove 12 on the rear side of the base 4 and connects to the corresponding cable. During wiring, simply open the rear door 3 of the distribution cabinet, connect one end of the cable to the terminal block 13, and lay the remaining part along the wiring groove 12 and fix it with a wiring clip, thereby avoiding cable clutter and improving overall neatness and safety. All cables enter or exit from the inlet / outlet port 15 at the bottom of the distribution cabinet. To secure the cables and seal the inlet / outlet port 15, the distribution cabinet is equipped with a movable plate 18 structure. The sponge clips on the rear side of the movable plate 18 and the front side of the fixed plate 16 close together to wrap the cable. At this time, the spring pin 20 automatically inserts into the corresponding socket 19, locking the movable plate 18, thus securing the cable and sealing the inlet / outlet port 15, effectively preventing dust, insects, and other foreign objects from entering the cabinet 1 and ensuring safe equipment operation.

[0022] Working Principle: This distribution cabinet designs circuit breakers, contactors, frequency converters, etc., as independent functional modules 6 with uniform external dimensions. Functional modules 6 are slidably connected to limit frames 5 to ensure accurate mating between female connectors 7 and male connectors 8 on the base 4. After mating, the rear end of the hand-tightening bolt 10 is threaded to the nut 11 at the front end of the base 4 by tightening the hand-tightening bolt 10, thus fixing the functional module 6. To prevent mis-insertion of connectors, each functional module 6 is numbered corresponding to its position on the base 4. The rear end of the male connector 8 is connected to a terminal block 13, which passes through the wiring groove 12 on the rear side of the base 4 and connects to the cable. During wiring, simply open the rear door 3 of the distribution cabinet, connect one end of the cable to the terminal block 13, and route the remaining cables within the wiring groove 12, securing them with wiring clips to prevent cable tangling. Both the incoming and outgoing cables pass through the vehicle inlet cable at the bottom of the distribution cabinet. Move the movable plate 18 so that the sponge clip on the back of the movable plate 18 closes with the sponge clip on the front of the fixed plate 16. At this time, the spring pin 20 is inserted into the socket 19 to fix the movable plate 18, while the sponge clip wraps the cable and seals the inlet and outlet ports 15.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
