[0002] The development of MT multi-core expander and optical transducer technologies has helped companies address market challenges such as high manufacturing costs and complex installation. With the continued growth in demand for fiber optic connections from data centers and high-speed networks, the market demand for MT multi-core expanders and optical transducers is expected to continue to expand. This provides companies with ample room for development and future growth potential.

[0003] In the prior art, a high-density MT beam-expanding optical cable assembly with authorization announcement number CN215895026U includes a beam splitter. Single-core optical fibers and multi-core optical fibers are respectively inserted and assembled at the left and right ends of the beam splitter. An MT movable plug is assembled at the right end of the multi-core optical fiber. A non-contact structure is inserted and assembled at the left end of each single-core optical fiber, and a beam-expanding fiber contact is inserted and assembled at the left end of each non-contact structure. This invention, through the structure of the MT movable plug, multi-core optical fiber, beam splitter, single-core optical fiber, and beam-expanding fiber contact, can effectively expand multiple optical signals and transmit them to multiple single-core optical fibers. Utilizing the MT movable plug, it can be used in special environments such as confined spaces, achieving a high-density integration effect.

[0026] Example 1

[0027] Please see Figures 1-8This utility model provides a technical solution: an anti-wear protection structure for an optical cable assembly, comprising: a first aluminum alloy shell 1 and a second aluminum alloy shell 2, wherein the first aluminum alloy shell 1 is provided with a sliding groove 3, a slider 4 is provided in the sliding groove 3, a rotating mechanism 6 is provided on the slider 4, the other end of the rotating mechanism 6 is connected to a connecting plate 13, the connecting plate 13 is connected to a pressure plate 9, the pressure plate 9 is provided with a friction pad 10 and a limiting post 11, the limiting post 11 is connected to a limiting plate 12, the limiting plate 12 is connected to a first support ring 7, the first support ring 7 is provided with a first rubber pad 8, and a first spring 15 is provided on the side of the first support ring 7; the second aluminum alloy shell 2, the second aluminum alloy shell 2 is provided with a second support ring 17, the second support ring 17 is provided with a second rubber pad 18, and a second spring 20 is provided on the side of the second support ring 17;

[0028] In practical use, the threaded end of the rotating mechanism 6 rotates along the threaded hole on the connecting plate 13, causing the pressure plate 9 and the limiting post 11 to slide. This causes the friction pad 10 on the pressure plate 9 to contact the side of the optical cable and squeeze the optical cable, thus fixing the optical cable between the first support ring 7 and the second support ring 17. When the optical cable is dragged, the second support ring 17 and the first support ring 7 slide, while the optical cable, fixed between the second support ring 17 and the first support ring 7, will not slide, thus protecting the optical cable.

[0029] Example 2

[0030] Based on Embodiment 1, a first rubber pad 8 is provided to improve the device's performance. The first rubber pad 8 is fixedly connected to the first support ring 7. A first spring 15 is fixedly installed on the side of the first support ring 7, and the other end of the first spring 15 is fixedly installed on the first aluminum alloy housing 1. The optical cable is placed at the second support ring 17, and another piece of the first aluminum alloy housing 1 is installed on the second aluminum alloy housing 2. The second aluminum alloy housing 2 and the first aluminum alloy housing 1 are connected by bolt threads, as in the example. Figure 3 As shown, at this time, both the first rubber pad 8 and the second rubber pad 18 are in contact with the side of the optical cable;

[0031] The threaded end of the rotating mechanism 6 is threadedly connected to the threaded hole on the connecting plate 13. The connecting plate 13 has an "L" shaped plate structure and is fixedly connected to the pressure plate 9. The pressure plate 9 is fixedly connected to a friction pad 10 and a limiting post 11. The limiting post 11 is slidably connected to the limiting plate 12. The limiting plate 12 is fixedly connected to the first support ring 7. Personnel can rotate the rotating mechanism 6 to make the threaded end of the rotating mechanism 6 rotate along the threaded hole on the connecting plate 13, so that the pressure plate 9 and the limiting post 11 slide. The limiting post 11 and the limiting plate 12 are slidably connected. The limiting plate 12 limits the limiting post 11 and the pressure plate 9, so that the friction pad 10 on the pressure plate 9 contacts the side of the optical cable and squeezes the optical cable, so that the optical cable is fixed between the first support ring 7 and the second support ring 17.

[0032] The inner side of the second aluminum alloy housing 2 is provided with a second limiting hole 19. The second limiting hole 19 has a circular hole structure. A second limiting rod 21 is provided in the second limiting hole 19. The second limiting rod 21 can slide along the second limiting hole 19. The other end of the second limiting rod 21 is fixedly connected to the second support ring 17. When the optical cable is dragged, the second limiting rod 21 fixedly connected to the second support ring 17 slides along the second limiting hole 19, causing the second spring 20 to extend and retract.

[0033] The inner side of the first aluminum alloy housing 1 is provided with a first limiting hole 14, which is a circular hole structure. A first limiting rod 16 is provided in the first limiting hole 14. The first limiting rod 16 can slide along the first limiting hole 14. The other end of the first limiting rod 16 is fixedly connected to the first support ring 7. The first limiting rod 16 fixedly connected to the first support ring 7 slides along the first limiting hole 14, causing the first spring 15 to extend and retract. The second support ring 17 and the first support ring 7 slide. The first spring 15 and the second spring 20 serve as a reset component. After the optical cable is no longer dragged, the first support ring 7 can be pulled back to its initial position.

[0034] A second rubber pad 18 is fixedly connected to the second support ring 17, and a second spring 20 is fixedly installed on the side of the second support ring 17. The other end of the second spring 20 is fixedly installed on the inner side of the second aluminum alloy housing 2. Through the above cooperation, the optical cable is protected by setting the second support ring 17 and the first support ring 7, which effectively reduces the phenomenon of optical cable damage caused by friction between the optical cable and the clamping hole after being dragged, and effectively improves the reliability of the device during operation.

[0035] Example 3

[0036] To improve the reliability of the device based on Embodiment 2, a first aluminum alloy housing 1 is provided. A sliding groove 3 is provided on the first aluminum alloy housing 1. The sliding groove 3 has a square groove structure. A slider 4 is provided in the sliding groove 3. The slider 4 has a square plate structure and can slide along the sliding groove 3. A protective plate 5 is fixedly connected to the side of the slider 4. The protective plate 5 has a square plate structure and contacts the first aluminum alloy housing 1. By setting the protective plate 5 at the sliding groove 3, dust and other impurities are prevented from entering the assembled device and thus affecting the operation of the optical cable.

[0037] In actual use, the threaded end of the rotating mechanism 6 rotates along the threaded hole on the connecting plate 13, causing the pressure plate 9 and the limiting post 11 to slide. This causes the friction pad 10 on the pressure plate 9 to contact the side of the optical cable and squeeze the optical cable, thus fixing the optical cable between the first support ring 7 and the second support ring 17. When the optical cable is dragged, the second support ring 17 and the first support ring 7 slide, but the optical cable, fixed between the second support ring 17 and the first support ring 7, will not slip. By setting the second support ring 17 and the first support ring 7 to protect the optical cable, the damage to the optical cable caused by friction between the optical cable and the clamping hole after being dragged is effectively reduced, thus effectively improving the reliability of the device during operation.
