[0002] The military aircraft cable is an important component of the aircraft electrical system, and undertakes the key task of power transmission and signal transmission. Its working environment is extremely harsh, and it is in complex working conditions of long-term high vibration, strong friction, high temperature, low temperature and high-low temperature mutation. Such a harsh environment causes the cable insulation layer to be easily damaged due to mechanical wear, thermal aging and chemical corrosion, and further causes short circuit, signal interruption and even fire accidents, which directly threatens flight safety.

[0003] At present, the aircraft cable protection mainly relies on manual winding of insulating tape or protection materials without adhesive. This method has the following disadvantages:

The constraint ring is flexibly connected to the main frame through a bracket, adapting to the limiting needs of curved or branched wire harnesses, solving the operational limitations of traditional methods on complex wiring.

[0025] 4. Lightweight structure and portability optimization: The main frame and handle are designed as an integrated unit, conforming to human engineering, and the hanging hole is set for tool storage; the rotating ring adopts a ball anti-friction structure (first / second ring groove with ball), reducing the rotation resistance and making single-handed operation more flexible, suitable for high-altitude or narrow-cabin operations.

[0026] 5. Modular design enhances expandability: The double-driven gear layout of the drive rod (distance > second opening width) ensures stable transmission, while the reserved interface facilitates the upgrade of intelligent control systems (such as tension sensors and speed regulation modules), laying the foundation for future functional expansion.
