A plurality of optical cables 300 can be inserted from the side wall of the box body 100. The inserted optical cables 300 are fixed inside the box body 100.

In order to facilitate the connection of the optical cable distribution assembly 400, both the ends of the optical input end 410 and the optical output end 430 are provided with an optical fiber plug 440. As shown in Figures 3 and 6. Since the optical output end 430 requires a certain length in actual use, in order to prevent the optical output end 430 from bending and folding at will in the box body 100, the optical output end 430 is wound on the fiber winding device 600, and the optical input end 410 is generally connected to the optical cable output end 320, so it generally does not need to be too long, and can be directly fixed to the bottom of the box body 100 with the splitter 420.

[0056] Of course, the number of adapters 700 needs to be adjusted according to actual needs, and this document does not make any specific restrictions.

[0057] Preferably, the fiber winding device 600 includes a plurality of stacked fiber winding drums 610, each of which is a cylindrical structure having a through hole 611 in the middle and a radial annular groove 612 on its circumferential edge. The through hole 611 is used to be sleeved on the fixed shaft 500, and the annular groove 612 is used to store the optical cable output end 320 and the optical output end 430.

[0058] Specifically, as shown in Figures 3, 7 and 10, the fiber winding device 600 is composed of a plurality of stacked fiber winding discs 610, and the fiber winding discs 610 are thin cylindrical structures. A through hole 611 is provided at the axis of the fiber winding device 600, that is, at the center of each fiber winding disc 610, and the through hole 611 can be just sleeved on the outer circumferential surface of the fixed shaft 500; in addition, an annular groove 612 is provided in the middle of the circumferential edge of each fiber winding disc 610, that is, a radial annular groove 612 is provided on the circumferential surface of the fiber winding disc 610, and the annular groove 612 on each fiber winding disc 610 can be used to wind an optical cable 300, so that multiple optical cable output ends 320 or optical output ends 430 can be wound and arranged at the same time.

[0059] Preferably, the outer diameters of the plurality of fiber winding discs 610 are gradually reduced in cross section along the extending direction of the fixed shaft 500 .

[0060] In order to facilitate winding of the optical cable 300 , the diameters of the plurality of fiber reels 610 gradually decrease from the bottom of the box body 100 upward along the fixed axis 500 , so that the pagoda-shaped structure facilitates winding of the optical cable 300 onto the fiber reels 610 .

[0061] Preferably, the fixed shaft 500 is a columnar structure, and its outer circumference is provided with a toothed structure, and the inner circumference of the through hole 611 is fixed with a spring piece 620 for engaging with the toothed structure on the fixed shaft 500 , and the spring piece 620 is used to limit the one-way rotation of the fiber winding disc 610 .

It should be noted that in this embodiment, the fiber winding disc 610 can only rotate clockwise.

[0065] Preferably, the spring piece 620 is made of elastic metal material.

[0066] It is understandable that when the fiber reel 610 rotates in a direction away from the protrusion, the protrusion will be compressed, so the material of the spring clip 620 needs to be elastic. At the same time, because the spring clip 620 is easily worn, in order to extend its service life, the material of the spring clip 620 is preferably an elastic metal material.

[0067] Preferably, the optical cable 300 is fixed to the bottom of the box body 100 by a saddle-shaped clamp 120 .
