Through the adapter in the distribution box, optical signals are led out with optical jumpers to realize the optical wiring function. It is suitable for the protective connection between optical cables and wiring pigtails, and is also suitable for the use of optical fiber terminal points in optical fiber access networks.

When the optical fiber passes through the wire holes, the anti-slip cover on the surface of the optical fiber may be scratched, which will cause the transmission effect of the optical fiber to deteriorate, thus affecting the use and causing consequences.

[0006] The effects achieved by the above components are: under the action of the protective device, the optical fiber will not be scratched when it is threaded, and under the action of the protective tube and the nut, the optical fiber will not be scratched when it is threaded. When using the distribution box, the optical fiber is passed through the threading hole, and then the optical fiber is inserted into the interior of the distribution box, and the optical fiber is wound on the surface of the winding frame through the limit device. Since the bending radius of the optical cable should not be less than times the outer diameter of the optical cable, it should not be less than times during the construction process, so that the radius of the winding frame is greater than times the outer diameter of the optical fiber, thereby connecting the other end of the optical fiber to the terminal board.
[0007] Preferably, a threading ring is fixedly connected to the interior of the protective tube, and a plurality of threading rings are arranged inside the protective tube.
[0008] The effect achieved by the above components is that, under the action of the threading ring, the optical fiber will not be entangled inside the protective tube.

[0015] Preferably, a clamping ring is fixedly connected to the surface of the telescopic adjustment frame, and the clamping ring is a rubber block.
[0016] The effect achieved by the above components is that under the action of the clamping ring, the optical fiber can be confined between the clamping rings, thereby achieving the limiting effect.
[0017] Preferably, a side surface of the telescopic adjustment frame is slidably connected to a slide rod, and the other end of the slide rod is fixedly connected to a push plate.

[0019] Preferably, a clamping rod is inserted into the surface of the telescopic adjustment frame, and the clamping rod is inserted into the interior of the sliding rod.
[0020] The effect achieved by the above components is: under the action of the clamping rod, the slide rod can be fixed after sliding to the appropriate position, thereby achieving the fixing effect. When the optical fiber needs to be limited, the screw rod is rotated, so that the rectangular plate pushes the telescopic adjustment frame to adjust the position. After the adjustment is completed, the optical fiber is wound on the surface of the telescopic adjustment frame. Under the action of the clamping ring, the optical fiber can be restricted between the clamping rings, thereby achieving the limiting effect. When the winding is completed, the push plate is moved to the inner wall of the distribution box through the slide rod. When it moves to the appropriate position, the clamping rod is inserted into the interior of the slide rod, thereby achieving the limiting effect.
[0021] Compared with the prior art, the advantages and positive effects of the utility model are:
[0022] In the utility model, by setting a protective device, when it is necessary to use the wiring box, the protective tube is inserted into the inside of the threading hole, and under the action of the film, the protective tube can be fixed inside the threading hole, and the nut is threaded together, and under the action of the clamping block, the nut will not slip, and under the action of the threading ring, the optical fiber will not be entangled inside the protective tube, thereby achieving the protective effect, thereby solving the problem that the surface of the optical fiber is easily scratched by the burrs and other sharp protrusions on the inner wall of the threading hole when the optical fiber passes through the threading hole.
