The following describes an embodiment of the present invention based on its overall structure.

[0030] Example

[0031] like Figures 1 to 3 As shown, a pressure-resistant optical cable box includes a mounting base 100 and a cap barrel 200 covered and buckled on the mounting base 100, the cap barrel 200 and the mounting base 100 are tightly connected. Specifically, a sealing ring 120 is formed on the mounting base 100, and the sealing ring 120 and the mounting base 100 are an integrated structure. A silicone layer is provided on the sealing ring 120, and the cap barrel 200 is covered and buckled on the sealing ring 120 so that the silicone layer is located between the cap barrel 200 and the sealing ring 120. The cap barrel 200 and the sealing ring 120 are squeezed to form a tight connection between the two to form a sealed cavity to prevent the entry of water vapor and insects.

[0032] The mounting base 100 is provided with an optical fiber mounting bracket 110, and the optical fiber mounting bracket 110 is installed on the mounting base 100 by bolt connection. Specifically, a fiber splicing box 130 is installed on the optical fiber mounting bracket 110, and a clamping plate 131 is installed inside the fiber splicing box 130. The clamping plate 131 is provided with a plurality of slots. The slots adopt a multi-arrangement split design, which can be used for multi-fiber coiling of 24 cores, 48 ​​cores, etc., to facilitate the clamping and fixing of the remaining optical fibers for coiling, and finally the cable is retracted and pressed to prevent the optical fibers from being exposed from the box body.

[0033] Furthermore, the mounting base 100 is provided with a plurality of threading holes 140, each of which is provided with a fastening nut 150. The threading hole 140 can also be configured as an aviation plug-like structure, so that a sealed cavity is formed inside, which acts as a seal. At the same time, it protects the outer layer of the optical cable during the fixing operation, preventing the entry of ants and other small insects, thereby protecting the optical fiber. When the multi-core optical cable passes through the inlet and outlet holes of the cast aluminum base, the fastening nut 150 is used to reinforce and lock the optical cable at the threading point of the cast aluminum base to prevent the optical cable from loosening and falling out of the cable box after installation.

[0034] The fiber fusion box 130 and the mounting base 100 are both made of aluminum alloy. It is worth mentioning that the entire optical cable box is made of alloy material to increase its compressive strength, and the alloy material of the outer shell is electrochemically treated to improve its waterproof, moisture-proof, corrosion-resistant, and sealing characteristics. At the same time, it can also enhance its mechanical properties, so that the optical cable box can be reused, repeatedly opened, expanded, repaired, and reconnected. The mounting base 100 is installed on the pole steel belt assembly 500 on the electric pole 400 through the S-type tower mounting frame assembly 300; wherein, the cap barrel 200 is electrochemically treated. The top surface of the hat barrel 200 is curved. The hat barrel 200 consists of two parts, one is the hat head at the top, and the other is the hat barrel body. The hat head is semi-spherical, and the hat barrel body is a cylindrical tube. The cylindrical tube and the semi-spherical shape are directly welded together to form a whole, and then electrochemically improved to improve its corrosion resistance. At the same time, the curved structure of the hat head can also prevent rainwater from accumulating on the top during rain. The curved structure can divert rainwater, further preventing humid weather from corroding and penetrating the outer shell and causing internal moisture.

[0035] Preferably, the pole steel belt assembly 500 includes a pole steel belt 510 and a steel belt installer 520 . The pole steel belt 510 is looped around the pole of the utility pole 400 and is locked by the steel belt installer 520 .

[0036] Preferably, the S-shaped tower mounting frame assembly 300 includes a support frame 310, an S-shaped tower hook 320, and a connecting bolt 330. The support frame 310 is mounted on the bottom of the mounting base 100. The support frame 310 and the S-shaped tower hook 320 are connected and locked by the connecting bolt 330. The S-shaped tower hook 320 is hooked on the pole steel belt 510. It is worth mentioning that the support frame 310 uses an aluminum bracket, which makes it lighter in use and avoids the accident of plastic bracket breaking.

[0037] Next, the operating procedures in this embodiment are described in detail to enable those skilled in the art to better understand the present invention:

[0038] Insert the optical fiber and transition hose sequentially through the threading hole 140 on the mounting base 100. The threading hole 140 is equipped with a rubber plug and a fastening nut 150. Adjust the diameter of the optical cable using the diameter adjustment washer (using the diameter adjustment washer to hold the optical cable in the threading hole 140), and then tighten the fastening nut 150 to seal the stainless steel unit (i.e., seal the optical cable and the threading hole 140 diameter to prevent the ingress of small insects, ants, and moisture). Insert the optical fiber threading and protection tube from the bottom of the mounting base 100 into the sealed cavity formed between the cap barrel 200 and the mounting base 100 (herein referred to as the fiber storage box) and secure it with a cable tie.

[0039] After working from bottom to top, confirm the installation quality and record the fiber connection color spectrum, connection points, attenuation, etc. on the fiber identification card. Before finally closing the cable box, clean the sealing area of ​​the splice box body, then pad it with a silicone ring, cover the cable box with the cap barrel 200, and tighten the seal with 6 M6 hexagon socket bolts.

[0040] The ADSS cable splicing process involves straightening the reserved ADSS cables and trimming any damaged or excess ADSS cables. The pair of cables to be spliced ​​are stripped and cleaned. The cables are then threaded through the diameter adjustment washers. All the hold-down bolts 150 on the mounting base 100 are tightened to secure the diameter adjustment washers tightly around the cables. The optical fibers are fed into the fiber storage cassette from the bottom and secured with cable ties. The fibers are then fusion-spliced ​​using conventional methods. The heat-shrink tubing for the fiber connectors is secured to the fiber storage tray (the retaining plate 131 on the splice cassette 130).

[0041] In summary, the present invention provides an optical cable box with pressure resistance. The optical cable box has high mechanical strength and good sealing performance. The alloy shell adopts electrochemical treatment, is corrosion-resistant, and has excellent performance. It adopts sealing rings and silicone seals, and can be repeatedly opened, expanded, repaired, and reconnected. The capacity of a single fiber storage tray reaches 48 cores. When the optical cable box provided by the present invention is connected to the optical cable, the optical cable is fixed with an adjustable diameter adjustment gasket to clamp (hold) to prevent the optical cable from being pinched. The optical cable box provided by the present invention can be installed in different parts of the tower and is firmly installed. (The pole installation adopts stainless steel belt for fixing, which is easy to operate and can be applied to installations with different pole diameters and different positions). After the optical fiber is fused, the optical fiber provided by the present invention is fixed to the optical fiber slots of the fusion box respectively. The excess optical fiber is coiled in the fusion box according to the optical fiber laying principle. The optical fiber is collected into the fusion box by using a U-shaped ring and covered with a sealing cover and a card. The fusion box with this structure is suitable for fusion operations of various high-altitude optical fibers, which brings great convenience to users.
