[0002] A cable is a device for transmitting electric energy or signals. It is usually a cable similar to a rope composed of several or several groups of wires twisted together. Each group of wires is insulated from each other and is often twisted around a center. The whole is covered with a highly insulating covering layer. The cable has the characteristics of being energized inside and insulated outside. During the use of the cable, the connector is prone to damage and breakage due to friction or dragging. Therefore, a protection device is needed to provide protection for it.

[0003] Most of the existing protection devices are integrated. When installing, the staff needs to manually disassemble and reassemble them, and needs to turn screws for fixation, which is time-consuming and laborious, reducing the practicability. Most of the existing protection devices only have a simple anti-break function, and the dust-proof and insulation functions are not good, which is easy to cause safety hazards and reduce the safety. Therefore, we propose an anti-break protection device for a cable connector. Content of the Utility Model
