Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of optical fiber assembly, and particularly relates to a tail fiber protection device for optical fiber assembly based on foam material. BACKGROUND

[0002] In the traditional optical fiber assembly process, the optical fiber assembly and the hydrophone are directly in a suspended state, which is unstable and greatly affects the assembly of the optical fiber array; or the optical fiber assembly is lifted by injection molding clamps, wood, etc., which can avoid the suspension of the optical fiber assembly; or a small turnover box is placed under the optical fiber assembly, the tail fiber is placed in the turnover box, and the height of each optical fiber assembly is maintained at a certain height. However, in this case, the optical fiber assembly is still in a suspended state, so the protection of the tail fiber is not good. In the above three cases, although the assembly of the array section plays a certain role in the requirement of being on the same plane, the protection of the optical fiber assembly, the hydrophone, the optical cable and the tail fiber is extremely small. Slight shaking of the array section may damage the optical fiber assembly, the hydrophone, the optical cable or the tail fiber. The optical fiber assembly, the hydrophone, the optical cable and the tail fiber are not well protected and are directly scattered on the workbench, which is not easy for the operator to find. In addition, the horizontal height is lower than the optical fiber assembly with the opening facing upward, which will be downward and bent due to the action of gravity, so the tail fiber is often broken accidentally during the assembly process. The length of the finished optical fiber needs to be strictly controlled, and the length that is too long or too short cannot be used. The length that is too long can be manually cut off, but once the tail fiber is broken, the length that is too short cannot be used, which will result in the optical fiber assembly being scrapped. SUMMARY

[0017] A fiber placing area 2 is recessed on the other side of the top of the foam plate body 1, and the inside of the fiber placing area 2 is used for placing the scattered fiber, in the embodiment, the fiber placing area 2 is circular, which is more convenient for placing the fiber, and the force rope placing groove 5 and the fiber cable and hydrophone fixing groove 3 are long strip-shaped and respectively penetrate through the upper two sides of the foam plate body 1. In the use process, the fiber assembly with the optical unit connected at both ends can be placed into the fiber assembly positioning area 4, the force rope is placed into the force rope placing groove 5, and the hydrophone is clamped in the fiber cable and hydrophone fixing groove 3. The thickness of the bottom of the fiber cable and hydrophone fixing groove 3 is not less than the height of the fiber assembly positioning area 4 in the air, so that the fiber assembly positioning area 4 is no longer in the suspended state, that is, the height of the bottom of the fiber cable and hydrophone fixing groove 3 is not less than the height of the bottom of the fiber assembly positioning area 4.

[0018] As an embodiment, the fiber placing area 2 is adjacent to the force rope placing groove 5 arranged on the inside of the foam plate body 1, the fiber placing area 2 has a guide part 11, the depth of the guide part 11 is consistent with the depth of the fiber placing area 2, the guide part 11 is communicated with the force rope placing groove 5 on the inside, and a through opening is arranged on the side wall of the force rope placing groove 5 on the side close to the fiber placing area 2, the bottom of the through opening is flush with the bottom of the guide part 11.
