The fixing mechanism is provided with a limiting assembly, and there are two limiting assemblies, which are respectively relatively installed at two ends below the inside of the fixing groove. The limiting assembly includes a plurality of support tubes fixedly connected to the lower surface of the inside of the fixing groove, a support rod is slidably connected to the inside of the support tube, and an elastic member is arranged on the outside of the support rod.

[0003] The above technical solution is to pass the entire optical cable through the first heat shrink tube and insert it into the supporting groove, the optical cable is placed on top of the supporting ring, and then when the lid is closed, the pressure ring will press the optical cable downward until the support rod slides downward inside the supporting tube, and the elastic member deforms to generate elastic potential energy, which has a force to push the supporting ring upward, thereby combining with the downward pressure of the pressure ring to clamp the optical cable between the pressure ring and the support ring, thereby limiting and fixing the optical cable to prevent it from moving in the supporting groove; however, in actual use, the pressure ring and the support ring can only limit the optical cable under the elastic force of the elastic member, but when the optical cable is pulled, the optical cable will also slide laterally, causing damage between the optical cable and the branch line, affecting the life of the optical cable and signal transmission, and the structure has poor sealing performance.

[0004] To this end, the utility model provides an optical cable branching protection structure. Utility Model Content
