[0022] First, the optical fiber is passed through the optical fiber connection seat 3 and inserted into the interior of the box body 1. The longer optical fiber is wound on the arc winding plate 10 through the winding assembly 7. Since the arc winding plate 10 has the largest diameter, the longer optical fiber can be wound. Then, according to the thickness of the next group of optical fibers, the plug 11 at the lower end of the arc positioning plate 13 is inserted into the appropriate socket 9, so that the distance between the arc positioning plate 13 and the arc winding plate 10 is larger than the diameter of the next group of optical fibers, so that the next group of optical fibers can be wound on the outside of the four arc positioning plates 13. The rubber ring 12 increases the friction between the plug 11 and the socket 9. The last group of optical fibers is wound on the outside of the arc positioning plate 2 14.

[0023] In this embodiment, fixing plates 4 are fixedly installed at the four corners of the box body 1 , and mounting bolts 5 penetrate through the upper ends of the fixing plates 4 . A sealing cover 6 is movably installed at the upper end of the box body 1 .

[0024] The mounting bolts 5 facilitate fixing the box body 1 .

[0025] In this embodiment, a connector 21 is fixedly installed near the middle position of the box body 1 , and a clamping assembly 8 is provided on an inner wall of one side of the box body 1 to match the pigtail connector 2 .

[0026] In this embodiment, a clamping assembly 8 includes a clamping block 15 , and a through hole 16 is formed on one side of the clamping block 15 . The through hole 16 and the connecting hole of the pigtail connector 2 are kept in a horizontal position.

[0027] In this embodiment, a large-notch rubber seat 17 is fixedly installed on the inner wall of the through hole 16 , and the length of the large-notch rubber seat 17 is consistent with the length of the clamping block 15 . A small-notch rubber seat 18 is arranged inside the through hole 16 at a symmetrical position to the large-notch rubber seat 17 .

[0028] In this embodiment, two plastic screws 19 are passed through the external threads of the clamping block 15 , and one end of the plastic screw 19 is movably engaged in the interior of the sleeve 20 , and the sleeve 20 is fixed to the exterior of the small-notch rubber seat 18 .

[0029] Through the provided clamping assembly 8, after the pigtail is passed through the through hole 16 of the clamping block 15, the two plastic screws 19 are rotated at the same time to move the small-notch rubber seat 18 toward the large-notch rubber seat 17, so that the pigtail contacts the inner surfaces of the small-notch rubber seat 18 and the large-notch rubber seat 17, thereby clamping and positioning the pigtail to prevent one end of the pigtail from loosening after the connector 21, which would lead to poor contact.

[0030] The implementation principle of the fiber optic coiling box of the embodiment of the present application is as follows: first, the optical fiber is passed through the optical fiber connection seat 3 and inserted into the interior of the box body 1, and the longer optical fiber is wound on the arc winding plate 10 through the provided winding assembly 7. Since the diameter of the arc winding plate 10 is the largest, the longer optical fiber can be wound, and then according to the thickness of the next group of optical fibers, the plug 11 at the lower end of the arc positioning plate 13 is inserted into the appropriate plug hole 9, so that the distance between the arc positioning plate 13 and the arc winding plate 10 is larger than the diameter of the next group of optical fibers, so that the next group of optical fibers can be wound on the four arc positioning plates. On the outside of plate 13, the rubber ring 12 increases the friction between the plug 11 and the socket 9. The last group of optical fibers is wound around the outside of the arc-shaped positioning plate 2 14. Through the clamping assembly 8, the pigtail is passed through the through hole 16 of the clamping block 15, and then the two plastic screws 19 are rotated at the same time to move the small-notch rubber seat 18 toward the large-notch rubber seat 17, so that the pigtail contacts the inner surface of the small-notch rubber seat 18 and the large-notch rubber seat 17, thereby clamping and positioning the pigtail to prevent one end of the pigtail from loosening after the connector 21, which may lead to poor contact.
