[0019] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it is not construed as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] As Figures 1-3 It is a schematic structural diagram of a ring main unit in a preferred embodiment of the present utility model. In this embodiment, a ring main unit includes a cabinet body 1. An installation cavity 2 is provided inside the cabinet body 1. Connecting frames 3 are fixedly installed on both sides of the inner wall of the installation cavity 2. An installation frame 4 is bolted between the two connecting frames 3, so that the installation frame 4 can adjust the distance between it and the inner wall of the installation cavity 2, improving the convenience of later maintenance. A fixing frame 17 is fixedly installed at the rear corner of the installation cavity 2 inside the installation frame 4. A first wiring box 5 is installed on the surface of the fixing frame 17. The first wiring box 5 is used to sort out and summarize the incoming and outgoing wires inside the ring main unit. In addition, a second wiring box 6 is fixedly installed on the rear end face of the installation frame 4, which can sort out and summarize the connecting wires of the electrical components installed on the installation frame 4, thereby distinguishing the connecting wires between them and facilitating subsequent maintenance work.

[0022] In this embodiment, the first wiring box 5 and the second wiring box 6 have the same structural design.

[0023] In this embodiment, the first wiring box 5 includes a fixing seat 10 and a wiring cover 9. The wiring cover 9 is snap-connected to the surface of the fixing seat 10 for connection and fixation. A wiring cavity 16 is formed between the top surface of the fixing seat 10 and the bottom surface of the wiring cover 9. The wiring cavity 16 is used to sort out and summarize the connecting wires.

[0024] In this embodiment, two first connection blocks 12 are fixedly connected to both sides of the top of the fixing seat 10. A connection groove 13 is formed on the surface of the first connection block 12. Second connection blocks 11 are fixedly connected to the bottom of the wiring cover 9 at positions opposite to the first connection blocks 12. The second connection blocks 11 are made of elastic plastic. A connection block 14 is fixedly connected to the surface of the second connection block 11, so that the connection block 14 is snap-connected into the connection groove 13. Specifically, when the fixing seat 10 and the wiring cover 9 are snap-connected to each other, the operator needs to squeeze the second connection blocks 11 inward, making the distance between the two second connection blocks 11 smaller. Then, the connection block 14 is aligned with the connection groove 13. The operator releases the second connection blocks 11, and the second connection blocks 11 reset, thus completing the snap connection between the connection block 14 and the connection groove 13.

[0025] In this embodiment, a plurality of through holes 15 are provided at positions on the outer wall of the second connection block 11 corresponding to the wiring cavity 16, facilitating the connection of connection lines.

[0026] In this embodiment, a door body 7 is fixedly connected to the front surface of the cabinet body 1 at a position corresponding to the installation cavity 2 through a hinge, and a storage box 8 is fixedly installed on the inner wall of the door body 7. The storage box 8 is designed to facilitate the storage of maintenance records and maintenance tools.
