Specifically, in various electrical cabinets, such as power distribution cabinets and air conditioning cabinets, interactive interfaces, various sensors, signal lights, etc. are often arranged on the front and back doors of the cabinet. However, as the functionality of the cabinet becomes richer and richer, the number and types of cables between the cabinet and the cabinet door are also increasing, causing great difficulties in the product wiring process. When designing the product, it is necessary to consider the internal and external structure of the cabinet and the cable routing to prevent damage to the cables after long-term use.

[0003] In actual daily applications, communication lines, signal lines, etc. are exposed between the cabinet doors and the cabinet body. The cabinet doors are frequently opened and closed during daily use of the equipment, and the connecting cables are likely to hinder the opening and closing of the cabinet doors during the process of opening and closing the doors. Without protection, the cables will bend repeatedly and easily get caught in the gap between the cabinet doors and the cabinet body, causing breakage or fatigue fracture of the cables, resulting in equipment failure and even endangering the personal safety of the operators. Related technologies mostly use hollow shafts to solve the problem of exposed wires. However, during the daily opening and closing of the doors, the middle cables will still rotate with the cabinet doors, causing twisting problems, resulting in wear and loss of conductive function, which in turn causes equipment failure.
