[0023] Figure 1-4 This invention illustrates a wiring distribution assembly for a power distribution cabinet according to an embodiment of the present invention. The assembly includes a fixed plate 1. A U-shaped frame 2 and a carrier plate 3 are fixedly mounted on the surface of the fixed plate 1. A main control circuit breaker 4 is disposed above the fixed plate 1. A U-shaped block 5 is integrally formed on the surface of the U-shaped frame 2. A threaded rod 6 is rotatably connected to the inner wall of the U-shaped block 5. A threaded sleeve block 7 is threadedly connected to the surface of the threaded rod 6. A vertical rod 8 is welded to the surface of the threaded sleeve block 7. A limiting groove 9 adapted to the vertical rod 8 is formed on the surface of the U-shaped frame 2. A rotating shaft 11 is rotatably connected to the inner wall of the U-shaped frame 2. A connecting block 12 is fixedly connected to the surface of the rotating shaft 11.

At the same time, the busbar block is isolated by the insulating isolation block 18, realizing the clamping of the busbar block by the epoxy resin block, so that the busbar block is mutually insulated and isolated at the wiring distribution point below the main control circuit breaker and the connection between it and the cabinet is stable.

[0025] In summary: This distribution cabinet wiring distribution assembly, through the swing of the connecting block 12, drives the pressure plate 15 to swing, and then the pressure plate 15, through the insulating pressure block 17, applies force to press the busbar block onto the surface of the carrier plate 3. Subsequently, the pressure plate 15 and the carrier plate 3 are locked together by the bolt rod 16, and the busbar block is isolated by the insulating isolation block 18. This achieves the purpose of clamping the busbar block with epoxy resin blocks, so that the busbar blocks are mutually insulated and isolated at the wiring distribution point below the main control circuit breaker, and the connection between the busbar block and the cabinet is stable.
