Description

Technical Field

[0001] This utility model relates to the field of optical fiber cabling structure technology, specifically to an optical fiber cabling positioning structure. Background Technology

[0002] With the rapid development of communication technology, optical fiber, as a high-speed transmission medium, is widely used in scenarios such as computer room cabling, building communication, and outdoor pipeline networks. The physical characteristics of optical fiber place extremely high demands on cabling. Excessive bending, compression, or displacement can lead to signal attenuation and affect transmission quality.

[0003] Currently, common fiber optic cabling positioning methods often use nylon cable ties or simple plastic clips. These methods have several significant drawbacks: First, the installation process is cumbersome, making rapid cabling and subsequent adjustments difficult. Second, they lack effective elastic support and cushioning, and the cable tie tightening force is difficult to control, easily compressing the cables. Third, it is difficult to achieve neat, orderly arrangement and precise positioning of cables, especially in high-density cabling environments, easily leading to cable crossings and tangles, affecting not only aesthetics but also posing significant challenges to later maintenance, identification, and replacement.

The physical characteristics of optical fiber place extremely high demands on cabling; excessive bending, compression, or displacement can lead to signal attenuation and affect transmission quality.

[0004] Currently, common fiber optic cabling positioning methods often use nylon cable ties or simple plastic clips. These methods have the following obvious drawbacks: First, the installation process is cumbersome, making it difficult to quickly lay cables and adjust them later. Second, they lack effective elastic support and cushioning, and the tightening force of the cable ties is difficult to control, easily compressing the cables. Third, it is difficult to achieve neat, orderly arrangement and precise positioning of cables, especially in high-density cabling environments, which can easily lead to cable crossing and tangling, affecting not only aesthetics but also causing great difficulties for later maintenance, identification, and replacement. Summary of the Invention

[0005] Based on this, the purpose of this utility model is to provide a fiber optic cabling positioning structure to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic cabling positioning structure, including a base, the base having a plurality of mounting hole groups inside, a plurality of fixing frames connected to the back of the base, and the fixing frames corresponding to the mounting hole groups in position, an adsorption plate installed on the inner wall of the fixing frame, and two sets of first clamping frames and second clamping frames respectively connected inside the fixing frame, the first clamping frame having a first magnet installed inside, the second clamping frame having a second magnet installed inside, and elastic sheets connected to the back of both sets of first clamping frames and second clamping frames.

[0007] Furthermore, several of the mounting hole groups are distributed in a rectangular array, and anti-slip washers are installed inside the mounting hole groups.

[0008] By adopting the above technical solution, the rectangular array of mounting holes can achieve orderly arrangement of optical fiber cables and accurately correspond to the interface position; the anti-slip washer embedded in each mounting hole has an inner hole that serves as a passageway for the optical fiber cable. The anti-slip washer is made of flexible elastic material. When the cable passes through, it can effectively fill the gap between the cable and the metal mounting hole, avoiding scratches or wear caused by direct contact between the sharp edge of the hole and the cable.

[0009] Furthermore, the elastic sheet has a concave arc surface structure and is made of flexible silicone material.

[0010] By adopting the above technical solution, the concave arc structure can better fit the outer surface of the round optical fiber cable, increasing the contact area. The use of flexible silicone material provides a soft and uniform clamping force, avoiding flattening or damaging the fragile optical fiber cable. On the other hand, its excellent elasticity can absorb some external impacts or vibrations, providing good buffer protection for the cable.

[0011] Furthermore, both sides of the two elastic sheets are connected to a sealing strip, and the two sealing strips are fixed together by a snap fastener.

[0012] By adopting the above technical solution, when the first clamping frame and the second clamping frame are closed, the sealing strips on both sides are firmly fastened by the concave and convex buckles, so that the two independent elastic pieces are connected to form a complete elastic protective sleeve that surrounds the cable. This design not only enhances the wrapping of the cable and prevents it from slipping off from the side, but more importantly, it forms an overall support structure that can effectively resist the lateral bending force of the cable and avoid the situation where the minimum bending radius of the optical fiber is insufficient near the interface.

[0013] Furthermore, both the first magnet and the second magnet are neodymium iron boron magnets, and the first magnet and the second magnet have different magnetic properties.

[0014] By adopting the above technical solution, using powerful neodymium iron boron magnets with opposite poles, a strong adsorption force can be generated. This allows the first and second clamping frames to automatically align and firmly engage when they are close together, achieving rapid locking and greatly simplifying the installation operation. At the same time, the magnetic fixing method does not require complex mechanical locking components, making it easy to open and close, and facilitating the insertion, adjustment, or removal of cables.

[0015] Furthermore, the fixing frame has an internal mounting groove, and the first clamping frame and the second clamping frame are detachably connected to the fixing frame through the mounting groove.

[0016] By adopting the above technical solution, the detachable connection method facilitates the later maintenance and replacement of the clamping frame; the mounting slot provides installation guidance for the clamping frame, ensuring accurate installation position. The mounting slot acts as a precise guide rail, ensuring that the first and second clamping frames can be smoothly pushed in or pulled out along the predetermined path, realizing rapid assembly and separation from the fixed frame. This modular design makes the replacement or maintenance of a single clamping frame very simple, without the need to disassemble the entire base.

[0017] Furthermore, the longitudinal section of the adsorption plate is inverted "T" shape, and the adsorption plate is made of cast iron.

[0018] By adopting the above technical solution, the inverted "T" shaped cross-section design makes the adsorption plate more firmly embedded in the fixing frame and less prone to loosening. The cast iron material has good magnetic conductivity and can form an efficient magnetic circuit with the neodymium iron boron magnet, which greatly enhances the magnetic attraction and fixing effect and ensures that the clamping frame remains stable in the fixing frame.

[0019] Furthermore, the first and second clamping frames are provided with limiting grooves on their exteriors, and the inner wall of the fixing frame is provided with reinforcing ribs.

[0020] By adopting the above technical solution, the cooperation between the reinforcing rib and the limiting groove constitutes a precise guiding and limiting system. When installing the clamping frame, this structure can effectively prevent it from deflecting or moving back and forth, ensuring that all clamping frames can be installed accurately and without error. This ensures the consistency, neatness and reliability of clamping multiple cables. At the same time, the reinforcing rib can also enhance the structural strength of the fixing frame, making the fixing frame less prone to damage.

[0021] Furthermore, both the first clamping frame and the second clamping frame are made of elastic plastic, and both the first clamping frame and the second clamping frame are coated with a nano anti-slip coating.

[0022] By adopting the above technical solution, the high-strength elastic plastic gives the clamp the necessary structural strength and service life, while having a certain deformation capacity to adapt to cables of different diameters. The nano anti-slip coating on the inner surface can significantly increase the static friction with the outer sheath of the cable, preventing the cable from sliding or shifting due to its own weight or external pulling after fixing, thus improving the reliability of fixing.

[0023] Furthermore, the anti-slip washer is made of nitrile rubber, and the inner wall of the anti-slip washer is provided with a smooth arc-shaped guide surface.

[0024] By adopting the above technical solution, the nitrile rubber material has both flexibility, wear resistance and a certain degree of oil resistance, which can provide the cable with durable and reliable flexible contact protection. The arc-shaped guide surface of the inner wall makes it easy and smooth for the cable to pass through, avoiding the obstruction caused by friction during the threading process. In the non-locked state, the anti-slip texture of the inner wall can provide appropriate static friction to prevent the cable from accidentally falling out of the hole due to its own weight or slight external force, thus ensuring the stability of the pre-installation stage.

[0025] In summary, the present invention has the following main advantages: 1. This utility model achieves rapid assembly and disassembly of the clamping unit through the modular design of the fixing frame, mounting groove and magnetic clamping frame. Workers can pre-install half of the clamping frame, and after the cable is connected, push the other half of the clamping frame in and fix it instantly by magnetic force, which greatly improves the wiring efficiency and is especially suitable for high-density, multi-cable batch installation scenarios. 2. This utility model provides a gentle and uniform clamping force by using a flexible silicone elastic sheet and a concave arc surface design, which effectively avoids the "stress point" pressure that traditional cable ties or hard buckles may cause to optical fiber cables. Combined with the enclosed strip and the concave and convex buckle to form a surrounding support structure, it can effectively limit the bending radius of the cable at critical interfaces, and fundamentally prevent optical signal attenuation or link failure caused by excessive bending. 3. This utility model utilizes the strong magnetic force generated by high-performance neodymium iron boron magnets, combined with cast iron adsorption plates and a precision limiting groove-reinforcing rib guide system, to ensure sufficient and stable locking force after the clamping frame is closed. It can resist certain external pulling and vibration, ensuring the reliability of long-term cable fixation. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A fiber optic cabling positioning structure, such as Figures 1-5 As shown, the device includes a base 1, with several mounting hole groups 2 inside the base 1. Several fixing frames 4 are connected to the back of the base 1, and the fixing frames 4 correspond to the mounting hole groups 2. An adsorption plate 6 is installed on the inner wall of the fixing frame 4. Two sets of first clamping frames 7 and second clamping frames 9 are connected inside the fixing frame 4 respectively. A first magnet 8 is installed inside the first clamping frame 7, and a second magnet 10 is installed inside the second clamping frame 9. An elastic sheet 11 is connected to the back of both sets of first clamping frames 7 and second clamping frames 9. The mounting hole groups 2 are distributed in a rectangular array, and anti-slip washers 3 are installed inside the mounting hole groups 2. The rectangular array of mounting hole groups 2 can realize the orderly arrangement of optical fiber cables and accurately correspond to the interface position. The anti-slip washers 3 embedded in each mounting hole have an inner hole that is a passage for optical fiber cables. The anti-slip washers 3 are made of flexible elastic material. When the cable passes through, they can effectively fill the gap between the cable and the metal mounting hole, avoiding scratches or wear caused by direct contact between the sharp edge of the hole and the cable.

[0031] See Figures 1-5 In the above embodiments, the elastic sheet 11 has a concave arc surface structure and is made of flexible silicone. The concave arc surface structure can better fit the outer surface of the round optical fiber cable and increase the contact area. The use of flexible silicone provides a soft and uniform clamping force on the one hand, avoiding flattening or damaging the fragile optical fiber cable; on the other hand, its excellent elasticity can absorb some external impacts or vibrations, providing good buffer protection for the cable.

[0032] See Figures 1-5In the above embodiment, both sides of the two elastic pieces 11 are connected to a sealing strip 12, and the two sealing strips 12 are fixed together by a snap fastener 13. When the first clamping frame 7 and the second clamping frame 9 are closed, the sealing strips 12 on both sides are firmly fastened by the snap fastener 13, so that the two independent elastic pieces 11 are connected to form a complete elastic protective sleeve that surrounds the cable. This design not only enhances the wrapping of the cable and prevents it from slipping off from the side, but more importantly, it forms an overall support structure that can effectively resist the lateral bending force of the cable and avoid the situation where the minimum bending radius of the optical fiber is insufficient near the interface.

[0033] See Figure 4 and Figure 5 In the above embodiments, both the first magnet 8 and the second magnet 10 are neodymium iron boron magnets, and the first magnet 8 and the second magnet 10 have opposite magnetic properties. The use of strong neodymium iron boron magnets and their opposite poles facing each other can generate a strong attraction force. This allows the first clamping frame 7 and the second clamping frame 9 to automatically align and firmly engage when they are close together, achieving rapid locking and greatly simplifying the installation operation. At the same time, the magnetic fixing method does not require complex mechanical locking components, making it easy to open and close, and facilitating the insertion, adjustment, or removal of cables.

[0034] See Figures 1-4 In the above embodiment, the fixing frame 4 is provided with an installation groove 5 inside, and the first clamping frame 7 and the second clamping frame 9 are detachably connected to the fixing frame 4 through the installation groove 5. The detachable connection method facilitates the later maintenance and replacement of the clamping frame. The installation groove 5 provides installation guidance for the clamping frame to ensure accurate installation position. The installation groove 5 serves as a precise guide rail, ensuring that the first clamping frame 7 and the second clamping frame 9 can be smoothly pushed in or pulled out along a predetermined path, realizing rapid assembly and separation from the fixing frame 4. This modular design makes the replacement or maintenance of a single clamping frame very simple, without the need to disassemble the entire base 1.

[0035] See Figure 4 In the above embodiment, the longitudinal section of the adsorption plate 6 is inverted "T" shape, and the adsorption plate 6 is made of cast iron. The inverted "T" shaped cross-section design makes the adsorption plate 6 more firmly embedded in the fixing frame 4 and less prone to loosening. The cast iron material has good magnetic conductivity and can form an efficient magnetic circuit with the neodymium iron boron magnet, which greatly enhances the magnetic attraction and fixation effect and ensures that the clamping frame remains stable in the fixing frame 4.

[0036] See Figure 4 and Figure 5In the above embodiments, the first clamping frame 7 and the second clamping frame 9 are provided with limiting grooves 15 on their exteriors, and the inner wall of the fixing frame 4 is provided with reinforcing ribs 14. The cooperation between the reinforcing ribs 14 and the limiting grooves 15 constitutes a precise guiding and limiting system. When the clamping frame is installed, this structure can effectively prevent it from deflecting or moving back and forth, ensuring that all clamping frames can be installed accurately and without error, thereby ensuring the consistency, neatness and reliability of clamping multiple cables. At the same time, the reinforcing ribs 14 can also enhance the structural strength of the fixing frame 4, making the fixing frame 4 less prone to damage.

[0037] See Figures 1-5 In the above embodiments, both the first clamping frame 7 and the second clamping frame 9 are made of elastic plastic, and both the first clamping frame 7 and the second clamping frame 9 are coated with a nano anti-slip coating. The high-strength elastic plastic gives the clamping frame the necessary structural strength and service life, while also having a certain deformation capacity to adapt to cables of different diameters. The nano anti-slip coating on the inner surface can significantly increase the static friction with the outer sheath of the cable, preventing the cable from sliding or shifting due to its own weight or external pulling after fixing, thus improving the reliability of fixing.

[0038] Example 2: To facilitate the smooth passage of the cable through the anti-slip washer 3, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 1 The anti-slip washer 3 is made of nitrile rubber, and the inner wall of the anti-slip washer 3 has a smooth arc-shaped guide surface. The nitrile rubber material has flexibility, wear resistance and a certain degree of oil resistance, which can provide the cable with durable and reliable flexible contact protection. The arc-shaped guide surface of the inner wall makes it easy and smooth for the cable to pass through, avoiding the obstruction caused by friction during the cable threading process. In the non-locked state, the anti-slip texture of the inner wall can provide appropriate static friction to prevent the cable from accidentally falling out of the hole due to its own weight or slight external force, thus ensuring the stability of the pre-installation stage.

[0039] The implementation principle of this utility model is as follows: First, the worker installs the base 1 on the frame corresponding to the interface position using bolts, ensuring precise alignment of the mounting hole group 2 with the interface. When installing the clamping frame, first push a second clamping frame 9 into the fixing frame 4 from the upper mounting groove 5, and then push a first clamping frame 7 into the lower mounting groove 5. Utilizing the magnetic attraction of the first magnet 8, the second magnet 10, and the adsorption plate 6, along with the guiding and limiting functions of the reinforcing rib 14 and the limiting groove 15, the first clamping frame 7 and the second clamping frame 9 are fixed in designated positions inside the fixing frame 4. The installation of the clamping frames for the remaining fixing frames 4 is completed sequentially. During cabling, one end of the optical fiber is passed through the mounting hole group 2. The anti-slip washer 3 initially fixes the cable through friction. Then, the crystal head is connected and inserted into the interface. Next, the first clamping frame 7 is pushed into the fixing frame 4 from the top and the second clamping frame 9 is pushed into the bottom. The optical fiber cable is firmly clamped by the opposite magnetic attraction of the first magnet 8 and the second magnet 10. Finally, the concave and convex buckles 13 are inserted into the two sealing strips 12, so that the elastic pieces 11 on the first clamping frame 7 and the second clamping frame 9 are connected into a whole, providing continuous and uniform support for the cable and avoiding damage to the optical fiber caused by excessive bending of the cable.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
