[0024] Please see Figures 1-4This utility model provides a technical solution: an optical fiber break point detection device, including a detection device base 1 and an optical fiber flexible positioning assembly. The optical fiber flexible positioning assembly includes a servo motor 3, a bidirectional screw 4, a moving plate 5, a clamping plate 6, a thin film pressure sensor 7, and a placement plate 8. The servo motor 3 is fixedly connected inside the detection device base 1, and the bidirectional screw 4 is rotatably connected inside the detection device base 1. The bidirectional screw 4 is fixedly connected to the output end of the servo motor 3. There are two moving plates 5, both of which are slidably connected inside the detection device base 1. Both moving plates 5 are threaded onto the outer surface of the bidirectional screw 4. There are multiple clamping plates 6, all of which are fixedly connected to the top of the moving plates 5. The clamping plates 6 are symmetrically distributed on the surfaces of the two moving plates 5. The number of thin film pressure sensors 7 is the same as the number of clamping plates 6, and they are all fixedly connected to the surface of the clamping plates 6. The placement plate 8 is fixedly connected to the top of the detection device base 1. There are multiple placement plates 8, all of which are symmetrically distributed on the surface of the detection device base 1. Both moving plates 5 are located at the bottom of the placement plate 8.
[0025] Furthermore, a detection device housing 2 is rotatably connected to the surface of the detection device base 1. A limit plate 20 is fixedly connected to the surface of the detection device base 1. A reinforcing rod 21 is fixedly connected to the surface of the limit plate 20. A support plate 22 is fixedly connected to the top of the limit plate 20. The support plate 22 is engaged with the detection device housing 2. A sliding groove 10 is formed on the surface of the detection device housing 2. A moving component 11 is slidably connected inside the sliding groove 10. A knob 12 is rotatably connected to the top of the moving component 11. A threaded rod 13 is rotatably connected inside the moving component 11. A slider 14 is fixedly connected to the surface of the moving component 11. A moving block 15 is slidably connected inside the moving component 11. The moving block 15 is threaded onto the outer surface of the threaded rod 13. A slot 16 is opened on the surface of the moving block 15. A locking block 17 is locked onto the surface of the moving block 15. A connecting rod 18 is fixedly connected to the surface of the locking block 17. A detection head 19 is fixedly connected to the surface of the connecting rod 18.

[0026] Furthermore, when using the device, rotate the outer shell 2 of the detection device by 90 degrees until it is in the position shown in the figure. At this time, the support plate 22 engages with the outer shell 2 of the detection device and limits its position, providing stable support for the outer shell 2 of the detection device. Then, place the optical fiber on top of the placement plate 8, start the servo motor 3 to drive the bidirectional screw 4 to rotate, thereby driving the two moving plates 5 to move closer to each other, and clamping and fixing the optical fiber through multiple clamping plates 6. The clamping force can be monitored in real time by the thin film pressure sensor 7 set on the clamping plate 6. If the clamping force is too large, control the servo motor 3 to reduce the clamping force. After fixing, remove the detection head 19 from the inside of the limiting plate 20. The locking block 17 is installed on the locking slot 16. After the locking block 17 and the moving block 15 are fixed, the slider 14 can be pushed to drive the moving component 11 to slide on the outer shell 2 of the detection device. Rotating the knob 12 drives the threaded rod 13 to rotate, thereby driving the moving block 15 and the detection head 19 to rise and fall, thereby adjusting the position of the detection head 19, which is convenient for breaking point detection on the surface of the optical fiber.
[0027] Furthermore, the flexible positioning component for optical fibers allows for dynamic adjustment of the clamping force, preventing scratches on the fiber surface or breakage of the internal fiber core due to excessive pressure. This reduces the risk of physical damage to the fiber during testing. The detachable mechanism enhances the overall portability and ease of use of the testing device. It also solves the problem that manually adjusting the clamping plate during clamping can not easily control the clamping force, which can cause excessive clamping force, resulting in fiber compression damage and reduced service life.
