[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] As attached Figure 1 To be continued Figure 4 As shown:
[0023] Example 1: This utility model provides a multi-channel branching device for drop optical cables, including a left fixing ring 2, a protective ring 4, and a guide ring 6; a branching ring 3 is provided inside the protective ring 4, and limiting rings 401 are fixedly connected to both sides of the protective ring 4. The left fixing ring 2 is movably installed on one side of the limiting ring 401, and a connecting ring 201 is provided on one side of the left fixing ring 2. The right fixing ring 5 is movably installed on the other side of the limiting ring 401. Insertion rings 7 are provided around the left fixing ring 2 and the right fixing ring 5, and branching rings 1 are movably installed inside the left fixing ring 2 and the right fixing ring 5.
[0024] Workers thread multiple branches of the drop cable into the branching rings 1 inside the left fixing ring 2 and the right fixing ring 5, and into the branching rings 3 inside the protective ring 4. The branching ring 1 engages with the limiting grooves 8 inside the left fixing ring 2 and the right fixing ring 5 via the outer limiting block 101, ensuring stable installation. The branching ring 3 further separates and guides the branching lines within the protective ring 4, preventing tangling. The protective ring 4 is made of flame-retardant, insulating, low-smoke, halogen-free polyolefin material, effectively buffering external impacts and isolating moisture and dust, protecting the cable branches from damage. When adapting to cables with different branch sizes, workers can separate the insertion rings 7 on the periphery of the left fixing ring 2 and the right fixing ring 5 from the insertion holes 402 of the limiting ring 401, disassemble the protective ring 4 from the left fixing ring 2 and the right fixing ring 5, and replace the branching rings 1 and 3 with the corresponding sizes to adapt to diverse usage scenarios.
[0025] In one embodiment of the present invention, a limiting groove 8 is provided on the inner side of the left fixing ring 2 and the right fixing ring 5, and a limiting block 101 is provided on the outer side of the dividing ring 1, and the limiting block 101 is fitted into the limiting groove 8.
[0026] The limiting block 101 can be embedded inside the limiting groove 8, which increases the friction between the split ring 1 and the left fixed ring 2 and the right fixed ring 5, and improves the stability of the split ring 1 installed inside the left fixed ring 2 and the right fixed ring 5.
[0027] In one embodiment of the present invention, the limiting ring 401 is provided with an insertion hole 402, and the insertion ring 7 is fitted into the insertion hole 402.
[0028] The insertion ring 7 can be inserted into the interior of the insertion hole 402, increasing the friction between the limiting ring 401 and the insertion ring 7, thus achieving a stable connection between the left fixing ring 2 and the right fixing ring 5 and the protective ring 4.
[0029] In one embodiment of this utility model, the guide ring 6 has a threaded groove inside, and the guide ring 6 is threadedly connected to the right fixed ring 5.
[0030] Working principle: Multiple branches of the drop fiber optic cable are inserted into the branching rings 1 inside the left fixing ring 2 and the right fixing ring 5, and the branching rings 3 inside the protective ring 4. The branching ring 1 is fixed by the outer limiting block 101 engaging with the inner limiting grooves 8 of the left fixing ring 2 and the right fixing ring 5. The branching ring 3 is separated and guided within the protective ring 4 to prevent tangling of the branching lines. The protective ring 4 is made of flame-retardant, insulating, low-smoke, halogen-free polyolefin material, which buffers external forces and isolates moisture and dust. By separating the outer insertion ring 7 of the left fixing ring 2 and the right fixing ring 5 from the insertion hole 402 of the limiting ring 401, the protective ring 4 can be disassembled from the left fixing ring 2 and the right fixing ring 5, allowing for the replacement of branching rings 1 and branching rings 3 of different sizes to meet diverse branch size requirements.
[0031] Example 2: This example is basically the same as the previous example, except that a guide ring 6 is movably installed on one side of the right fixed ring 5, a guide tube 602 is movably installed on one side of the guide ring 6, and a movable shaft 601 is provided between the guide tube 602 and the right fixed ring 5.
[0032] In one embodiment of this utility model, at least five guide tubes 602 and movable shafts 601 are provided.
[0033] The five guide tubes 602 can accommodate at least five branches of wires and cables.
[0034] In scenarios requiring multiple branches, the staff uses the threaded groove inside the guide ring 6 to thread it to the right fixed ring 5. After the optical cable branch line passes through the right fixed ring 5, it is further inserted into the guide tube 602 on one side of the guide ring 6. At least five guide tubes 602 can guide multiple branch lines in multiple directions to avoid mutual interference. The guide tube 602 is connected to the right fixed ring 5 through the movable shaft 601. The movable shaft 601 can rotate flexibly to achieve fine adjustment of the direction of the guide tube 602 to adapt to different wiring angle requirements. Based on the branch ring 1 and the branch ring 3, this structure further enhances the guiding stability and protection effect of the optical cable branch, meeting the precise wiring requirements of multi-branch scenarios.
[0035] Working principle: In multi-branch scenarios, the guide ring 6 is threadedly connected to the right fixed ring 5 via an internal threaded groove. After passing through the right fixed ring 5, the optical cable branch lines connect to the guide tube 602 on one side of the guide ring 6. At least five guide tubes 602 guide multiple branch lines in different directions to avoid interference. The guide tube 602 is connected to the right fixed ring 5 via a movable shaft 601. The movable shaft 601 rotates flexibly to fine-tune the direction of the guide tube 602, adapting to different wiring angles. This structure, based on the branch ring 1 and branch ring 3, further enhances the stability and protection of branch guidance, meeting the needs of precise multi-branch wiring.
[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
