A rotating mechanism for driving optical fibers in a hollow fiber fusion splicer

Abstract

This utility model discloses a rotating mechanism for driving optical fibers in a hollow-core optical fiber fusion splicer. The mechanism includes a rotating mechanism body, with an optical fiber rotation positioning mechanism mounted at the front. A rotating seat is mounted on the optical fiber rotation positioning mechanism, and a notch is formed on the surface of the rotating seat. An optical fiber is inserted through the notch. A conductive slip ring is mounted on the rotating mechanism body, and a driving ring is movably mounted inside the conductive slip ring. Connecting seats are fixedly mounted on both sides of the end of the driving ring, and the connecting seats are screwed to the end face of the rotating seat. This rotating mechanism allows the optical fiber to rotate during thermal fusion welding. By rotating the optical fiber, the optimal alignment angle can be found, reducing fusion loss caused by the irregularity of the optical fiber itself. This ensures that the two optical fibers can achieve ideal concentric alignment during fusion splicing, avoiding limitations on the transmission bandwidth and data transmission rate of the optical fiber communication system, which could lead to signal distortion and affect communication quality.

Description

Technical Field

[0001] This utility model relates to the field of optical fiber fusion splicers, specifically a rotating mechanism for driving optical fibers in a hollow optical fiber fusion splicer. Background Technology

[0002] The working principle of a fiber optic fusion splicer is as follows: Press the power switch to turn on the fusion splicer and wait for the device to complete its self-test. Open the fusion splicer's windproof cover and fiber clamps, and place the two cut optical fibers into their respective clamps, ensuring that the end faces of the fibers are aligned with the electrodes of the fusion splicer. Then, gently close the clamps and windproof cover. According to the type and specifications of the optical fibers, set the corresponding splicing parameters on the fusion splicer's operating interface, such as discharge time, discharge intensity, and advance amount. Generally, common single-mode and multimode optical fibers have default parameters, but in actual operation, fine-tuning may be necessary based on the quality of the optical fibers and the splicing effect. After setting the parameters, press the "fusion" button on the fusion splicer, and the fusion splicer will begin discharging and splicing the two optical fibers. During the splicing process, observe the fiber alignment and splicing process displayed on the fusion splicer's screen. If poor fiber alignment or splicing abnormalities are found, stop the splicing immediately and re-check and adjust the optical fibers. After the splicing is complete, the fusion splicer's screen will display parameters such as splicing loss. The splicing quality can also be judged by observing the appearance of the spliced ​​area. Generally, the fusion splice should be smooth, free of bubbles and cracks, and the two optical fibers should be tightly connected. If the fusion loss is too high or the appearance is unsatisfactory, the cause should be analyzed, such as uneven fiber end faces or incomplete fiber cleaning, and the fusion splice should be redone.

[0003] When splicing two optical fibers using a fiber optic fusion splicer, issues such as core eccentricity and substandard ellipticity may exist during the fiber manufacturing process, resulting in a non-perfectly regular fiber geometry. This irregularity leads to splicing losses during the splicing process, preventing concentric alignment and limiting the transmission bandwidth and data rate of the fiber optic communication system. Consequently, signal distortion and communication quality are affected. Utility Model Content

[0019] Please see Figure 1-5 This utility model provides a rotating mechanism for driving optical fiber in a hollow optical fiber fusion splicer, including a rotating mechanism body 1. An optical fiber rotation positioning mechanism 2 is installed at the front of the rotating mechanism body 1. A rotating seat 20 is provided on the optical fiber rotation positioning mechanism 2. A notch 21 is opened on the surface of the rotating seat 20. An optical fiber 3 is inserted into the notch 21. A conductive slip ring 14 is installed on the rotating mechanism body 1. A driving ring 11 is movably installed inside the conductive slip ring 14. A connecting seat 10 is fixedly provided on both sides of the end of the driving ring 11. The connecting seat 10 is screwed and fixed to the end face of the rotating seat 20.

[0020] Working Principle: In actual use, the device is first installed on the fiber optic fusion splicer. The fiber optic cable 3 is then passed sequentially through the insertion hole 132 and the notch 21 inside the rubber seat 131. Simultaneously, the pressure seat 22 is placed over the surface of the rotating seat 20. The pressure seat 22 is hinged to the rotating seat 20, preventing the fiber optic cable 3 from detaching from the notch 21 during rotation. The external switch of the conductive slip ring 14 is activated, causing the drive ring 11 inside the conductive slip ring 14 to rotate. The drive ring 11, through two sets of connecting seats 10, drives the fiber optic rotation positioning mechanism 2 to rotate, allowing the fiber optic cable 3 to rotate during hot-melt welding. By rotating the optical fiber 3, the optimal alignment angle of the optical fiber can be found, reducing the splicing loss caused by the irregularity of the optical fiber itself. This allows the two optical fibers to achieve ideal concentric alignment during splicing, avoiding situations that limit the transmission bandwidth and data transmission rate of the optical fiber communication system, leading to signal distortion and affecting communication quality. The diameter of the insertion hole 132 is smaller than the diameter of the optical fiber 3, so that when the optical fiber 3 passes through the insertion hole 132, the inner wall of the insertion hole 132 can squeeze the optical fiber 3, increasing the friction between the optical fiber 3 and the rubber seat 131. This causes the optical fiber 3 to rotate slowly along with the drive ring 11 as it rotates.

[0021] In a preferred embodiment, the rotating mechanism body 1 includes a connecting seat 10, a drive ring 11, a support seat 12, a positioning cylinder 13, and a conductive slip ring 14, with the support seat 12 screwed to the outer side of the conductive slip ring 14.

[0022] A positioning cylinder 13 is inserted inside the drive ring 11. A rubber seat 131 is fixedly installed inside the positioning cylinder 13. An insertion hole 132 is opened inside the rubber seat 131. The diameter of the insertion hole 132 is smaller than the diameter of the optical fiber 3.

[0023] In a preferred embodiment, the insertion hole 132 and the optical fiber 3 are installed with an interference fit, the insertion hole 132 and the notch 21 are arranged opposite to each other, and the axial cross-section of the insertion hole 132, the positioning cylinder 13, the rubber seat 131, the positioning cylinder 13 and the drive ring 11 is a concentric circle structure.

[0024] Four sets of positioning rails 134 are evenly arranged on the inner circumference of the drive ring 11, and four sets of positioning seats 133 are evenly arranged on the outer circumference of the positioning cylinder 13. The dimensions of the positioning seats 133 and the positioning rails 134 are matched, and the positioning seats 133 are inserted into the interior of the positioning rails 134.

[0025] In a preferred embodiment, the drive ring 11 and the positioning cylinder 13 are positioned and installed by four sets of positioning seats 133 and positioning rails 134, and the positioning seats 133 and positioning rails 134 are arranged in a dovetail shape.

[0026] The fiber optic rotation positioning mechanism 2 includes a rotating seat 20, a notch 21, and a pressure seat 22. The rotating seat 20 is driven to rotate by a conductive slip ring 14, and the surface of the rotating seat 20 is covered by the pressure seat 22.
