Multiple layers of connecting rings are fixedly connected inside the connecting sleeve, and a joint cavity is formed between two of the connecting rings. An anti-slip layer is attached to the outer and inner surfaces of the connecting rings.
[0006] Preferably, the cabinet surface has threaded holes around the connecting hole surface, and the mounting base surface has connecting holes at positions opposite to the threaded holes.
[0007] Preferably, the threaded hole and the connecting hole are connected by a fastener.
[0008] Preferably, the connecting cylinder is composed of a first connecting cylinder and a second connecting cylinder, and the first connecting cylinder and the second connecting cylinder are threadedly connected.
[0009] Preferably, an opening is provided in the middle of the inner wall of the connecting cylinder.

[0022] like Figure 1-3This is a schematic diagram of a preferred embodiment of the present invention for a through-wall sleeve for a switch cabinet. In this embodiment, the through-wall sleeve for a switch cabinet includes a cabinet body 1. Multiple fixing holes 11 are provided on one side of the outer wall of the cabinet body 1. A through-wall sleeve 2 is installed through the fixing holes 11. The through-wall sleeve 2 includes a mounting base 21 and a connecting sleeve 22. Mounting holes 213 are provided on the surface of the mounting base 21, and the connecting sleeve 22 is installed within the mounting holes 213. Multiple layers of connecting rings 223 are fixedly connected within the connecting sleeve 22, enabling connection with the switch cabinet. The connector has a plug-in connection function, and a plug-in cavity 224 is formed between the two connecting rings 223. The plug-in cavity 224 is used to realize the plug-in and connector connection. The outer and inner walls of the connecting rings 223 are attached with anti-slip layers 225 to prevent the connecting rings 223 from falling off during the connection process with the connector. Combined with the structural design of this utility model, its design structure is simple. By setting multiple layers of connecting rings 223 in the connecting cylinder 22, it can adapt to the connection of connectors with various apertures, thereby improving its adaptability, reducing replacement time, and making it more practical.
