There is a sealing strip 11 around the box door 3, and a lock catch 12 is provided on the box door 3. A fiber optic inlet 5 and a fiber optic outlet 6 are provided at the bottom of the box body 1. A cable fixing plate 7 is fixedly installed on the back plate of the box body 1. Above the cable fixing plate 7 is an insertion box 8. The insertion box 8 can rotate. A guide rail 9 is installed inside the insertion box 8. An integrated fiber splicing tray module tray 101 is inserted into the guide rail 9. Two upper and lower magnets 10 are fixedly installed on the back plate of the box body 1 on one side of the insertion box 8. Two hanging plates 4 are fixedly installed outside the box body 1, and fixing holes 14 are provided on the hanging plates 4.

[0025] Furthermore, the box body 1 is a hollow cuboid structure, with a length of 42 cm, a width of 16.5 cm, and a height of 45 cm. It has a small volume and can be installed on the wall through the fixing holes 14 on the hanging plates 4 with expansion bolts or on the electric pole with stainless steel buckles, saving space and production costs. Moreover, the box body 1 can accommodate up to 72 cores at most, which has far met the needs of users, rationally utilized resources, and avoided the phenomenon of wasting resources in the existing optical mating cable boxes.

[0026] Furthermore, a fiber optic cable inlet 5 and a fiber optic cable outlet 6 are provided at the bottom of the box body 1. The optical cable enters through the fiber optic cable inlet 5 and is fixed to the back plate of the box body 1 through the optical cable fixing plate 7. The fiber optic cable inlet 5 and the fiber optic cable outlet 6 are circular and larger than the diameter of the optical cable, so that the optical cable can be well fixed and protected. After the drop cable is connected to the fiber optic adapter 103 on the adapter integrated board 102, it is led out from the fiber optic cable outlet 6. After the optical cable is introduced and led out, the peripheries of the fiber optic cable inlet 5 and the fiber optic cable outlet 6 are sealed with putty, and then glue (a mixture of paraffin and rosin in a ratio of 1:1) is poured in for sealing to prevent water, dust and rodents from entering the box body 1.

[0027] Furthermore, the plug-in box 8 and the rotating shaft 13 are fixedly connected through a fixing structure. The plug-in box 8 is movably connected to the box body 1 through the rotating shaft 13. The plug-in box 8 can rotate. When maintenance is required, the plug-in box 8 is pulled out from the back plate of the box body 1 and rotated to a suitable angle for repair. When no repair is needed, the plug-in box 8 is rotated back to the back plate of the box body 1 and is fixedly adsorbed by two magnets 10 fixedly installed on the back plate of the box body 1. The positions of the magnets 10 on the back plate of the box body 1 are adapted to the positions where the plug-in box 8 is fixed on the back plate of the box body 1, so that the plug-in box 8 can be fixedly adsorbed on the back plate of the box body 1.

[0028] Furthermore, a guide rail 9 is installed inside the plug-in box 8, and the integrated fiber splicing tray module tray 101 is inserted into the guide rail 9. When maintenance is required, the integrated fiber splicing tray module tray 101 can be pulled out from the guide rail 9. After the maintenance work is completed, it is pushed back to the original position.

[0029] Furthermore, there is a sealing strip 11 around the box door 3. When the optical distribution box is not in use, the sealing strip 11 reduces the gap between the box door 3 and the box body 1, and the box door 3 and the box body 1 can be perfectly fitted and closed, playing a role in dust and moisture prevention. A lock catch 12 is provided on the box door 3, and the lock catch 12 can be perfectly fitted with the lock hole on the box body, playing a role in anti-theft. The box body 1 is made of cold-rolled steel plate and has electrostatic spraying on the surface, having good effects of dust and moisture prevention, lightning protection, anti-theft, anti-corrosion and rust prevention.

[0030] When using the miniaturized optical distribution box of the present utility model, first check whether the device is normal. The optical cable enters through the fiber optic cable inlet 5 and is fixed to the back plate of the box body 1 through the optical cable fixing plate 7. The optical cable is introduced into the integrated fiber splicing tray module tray 101, and then coiled around the inventory structure 104. The optical cable is stripped, and the stripped optical fiber is fused with the distribution pigtail. After fusion, a fiber optic heat shrinkable tube is sleeved. The distribution pigtail is inserted into the fiber optic adapter 103 on the adapter integrated board 102, and the corresponding fiber optic adapter 103 is connected with a drop cable. Finally, the drop cable is led out from the fiber optic cable outlet 6. Such a design not only has a small volume, simple operation, low production cost and maintenance cost, but also has a good dust and moisture prevention effect.

[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those skilled in the art, without departing from the concept of the present utility model, several modifications and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent.
