[0002] On circuit modules or sensors, in order to facilitate the fixing and installation of cables, cable connectors are often equipped on circuit modules or sensors. Most of the current cable connectors are extrusion fixing structures, which have poor waterproof performance. And after the cable is installed, during long-term use, due to the swaying of the cable, the cable is extremely prone to breakage at the installation location.

[0003] In the utility model patent with the Chinese patent publication number CN220022295U, a spring-type cable waterproof connector is proposed. This spring-type cable waterproof connector fixes its cable and at the same time increases the overall connection tightness. Therefore, compared with the current cable connectors, the utility model has good sealing and waterproof performance. At the same time, through the use of an anti-bending tube and the elastic force of the spring tube, the problem of damage to the cable caused by excessive bending at the installation location is prevented.

[0004] After studying the above patent technology, it is found that the fixing effect on the wire in the above device is effectively improved. Therefore, the utility model hereby proposes a wire protection sleeve for preventing bending, waterproofing and dustproofing. Content of the Utility Model
