The internal structure of the junction box is more conducive to application

The splicing box is also called the optical cable splicing box, which is mainly used for the connection of optical cables, and is suitable for the straight-through and branch connections of various structural optical cables such as overhead, pipeline, and direct burial. The box body is made of reinforced plastic with high strength, mature corrosion-resistant structure, reliable sealing and convenient construction.
The internal structure of the optical cable junction box mainly has the following several. The supporting frame is the main body of the internal components; the optical cable fixing device is used for fixing the optical cable and the base and the fixing of the optical cable strengthening element. The incoming and outgoing cables are sealed and fixed with a heat-shrinkable sheath; the optical fiber placement device can store optical fiber connectors and remaining optical fibers in an orderly manner. The length of the remaining optical fibers should not be less than 1 meter, and the winding diameter of the remaining optical fiber coils should not be less than 35mm. Among them, the storage tray can have up to four layers, the capacity is large, and the storage tray can be adjusted according to the number of cores connected by the optical cable; the optical fiber joint protection can also be used by placing the heat-shrinkable protective sleeve on the fiber core fixing clip in the storage tray. Silicone fixing method; the optical cable and the joint box are sealed. Use abrasive cloth to polish the joint between the joint box and the optical cable at the entrance of the optical cable and the base, wipe the polished area with a detergent, paste aluminum foil, and then put the heat shrinkable tube on the joint. At the cable entrance of the box, use a blowtorch to heat slowly in the middle first and then to both ends, so that the entire heat-shrinkable tube can be completely shrunk.
The junction box is indispensable in the current network installation. It is made of high-strength engineering plastics and added with anti-aging agents. It has high strength and good air and water tightness, and can adapt to harsh environments. The material selection and structural design of the junction box are very in line with the requirements of use.
