Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and more specifically, it relates to an optical fiber distribution frame. Background Technology

[0002] With the rapid development of fiber optic communication technology, fiber optic distribution frames play an increasingly important role in communication systems. Fiber optic distribution frames are mainly used to manage and connect different fiber optic lines to ensure the transmission quality and stability of fiber optic signals. However, existing fiber optic distribution frames often have certain shortcomings in fixing optical fibers, especially when dealing with a large number of optical fibers. Traditional distribution frames lack effective fixing structures for organizing and binding optical fibers, which makes the optical fibers prone to loosening, disorder, or even damage, thereby affecting the reliability of the system and the stability of signal transmission.

[0003] Traditional patch panels typically have a simple structure, making them unsuitable for different specifications or quantities of optical fibers. They lack flexibility and scalability, and are not easy to install and maintain quickly. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: A fiber optic distribution frame, comprising a distribution frame body, on which a cable bundling mechanism is provided. The cable bundling mechanism includes a mounting plate, a mounting base, a cable bundling sleeve, sliding rods, sliders, compression springs, clamping plates, and a pressing mechanism. The mounting plate is installed at the bottom end of the distribution frame body, the mounting base is fixed on the mounting plate, the cable bundling sleeve is installed on the mounting base, multiple sets of sliding rods are distributed inside the cable bundling sleeve, the sliders slide on multiple sets of sliding rods, multiple sets of compression springs are respectively connected to the inner sides of multiple sets of sliders, multiple sets of clamping plates are respectively installed at the bottom ends of multiple sets of compression springs, and the pressing mechanism includes a transmission sleeve, a push ring, a rotating sleeve, a toothed ring, a screw, a gear, and a positioning mechanism. The transmission sleeve slides on the outer wall of the cable bundling sleeve, the push ring is installed on the inner side of the transmission sleeve, the rotating sleeve is rotatably installed on the outer wall of the cable bundling sleeve, the toothed ring is installed on the inner wall of the rotating sleeve, multiple sets of screws are rotatably installed on the outer side of the cable bundling sleeve and threadedly connected to the transmission sleeve, and the gears are installed on the top of multiple sets of screws and mesh with the toothed rings.

[0008] The present invention is further configured such that the positioning mechanism includes a connecting sleeve, positioning holes, a support plate, a positioning block, an outer block, and a tension spring. The connecting sleeve is installed on the top surface of the rotating sleeve. Multiple sets of positioning holes are provided on the outer wall of the connecting sleeve. Multiple sets of support plates are provided on the outer wall of the cable harness sleeve. The positioning blocks slide within the multiple sets of support plates. The outer blocks are installed on the top of the multiple sets of positioning blocks. The tension spring is connected to the inner side of the multiple sets of outer blocks and is connected to the support plate.

[0009] This invention is further configured such that each of the multiple sets of sliding rods has a limiting strip on its outer wall, and the multiple sets of sliders are slidably connected to the multiple sets of limiting strips. Through the cooperation of the limiting strips and the sliders, the movement range of the sliders can be effectively limited, preventing excessive sliding or irregular movement, thereby ensuring the accuracy and stability of the wire harness mechanism during operation.

[0010] The present invention is further configured such that a compression spring is installed inside the cable bundle sleeve, and a push pad is installed at the bottom end of the compression spring. The elasticity of the compression spring can provide continuous pressure after the optical fiber is fixed, ensuring that the optical fiber always remains in a tight state. At the same time, the push pad, in cooperation with the compression spring, effectively and evenly distributes the pressure, avoiding excessive local pressure on the optical fiber.

[0011] The present invention is further configured such that rubber strips are provided on the inner sides of multiple sets of clamping plates, and multiple sets of rubber strips are provided and distributed on the inner sides of multiple sets of clamping plates. The rubber strips can effectively enhance the friction between the clamping plates and the optical fiber, prevent the clamping plates from damaging the optical fiber, and at the same time, through their elastic properties, make the clamping force more uniform, thereby improving the protection effect on the optical fiber.

[0012] The present invention is further configured such that a guide rod is provided inside the cable harness sleeve, and multiple sets of guide rods are provided, all of which are slidably connected to the push ring. The guide rod guides the sliding of the push ring, ensuring the stable movement of the push ring within the cable harness sleeve, avoiding jamming or imbalance of the cable harness mechanism due to irregular movement, thereby improving the smoothness and stability of the overall cable harness device.

[0013] The present invention is further configured such that the tops of the multiple sets of positioning blocks and the outer walls of the positioning holes are all arc-shaped. The arc-shaped design allows the positioning blocks to slide more smoothly within the positioning holes, reducing friction and jamming. At the same time, the arc-shaped design improves the accuracy of the positioning blocks, ensuring a more stable and reliable positioning process.

[0014] The present invention is further provided that both ends of the cable tie sleeve are provided with rounded corners. The rounded corner design reduces the scratches or damage that the cable tie sleeve may cause to the optical fiber during use, while making the installation and removal of the cable tie sleeve more convenient, thereby improving the durability and ease of use of the equipment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a fiber optic distribution frame, which has the following advantages:

[0017] 1. The fiber optic cable bundling mechanism effectively solves the problem of insecure fiber optic cable fixation through the coordinated operation of a series of precision components. The cable bundling sleeve, through the cooperation of the sliding rod and the slider, can precisely adjust the tightness of the fiber optic cable. The slider slides on the sliding rod, allowing the clamp to evenly clamp the fiber optic cable, preventing it from becoming loose or misaligned, and ensuring the stability and neatness of the fiber optic cable in the patch panel. In addition, the rubber strip inside the clamp can effectively prevent damage to the fiber optic cable and improve the uniformity of the clamping force, thereby enhancing the protection performance of the fiber optic cable. At the same time, the application of the compression spring can ensure that the clamp is always in a stable state through the elastic reset function, avoiding damage caused by excessive pressure on the fiber optic cable.

[0018] 2. The clamping mechanism provides efficient and adjustable fixing force through a set of gears, screws, and push rings. The rotating sleeve drives the gear ring to mesh with the gears, thereby driving the screw to rotate and achieving precise control of the transmission sleeve and push ring. The push ring can push the slider, which in turn drives the clamping plate to clamp the outer wall of the optical fiber, ensuring that the optical fiber can be firmly fixed under different conditions. During the optical fiber fixing process, the design of the push pad further enhances the stability of the optical fiber. The compression spring provides the necessary elastic support, ensuring that the optical fiber is not easily loosened by external forces after fixing.

[0019] 3. The positioning mechanism, through the precise design of the connecting sleeve, positioning hole, and support plate, can accurately position the rotating sleeve, preventing unnecessary displacement during operation. The positioning block, in cooperation with the positioning hole, not only ensures the accuracy of positioning but also provides additional support during fiber optic fixing. The elasticity of the tension spring helps provide stable tension between the positioning block and the outer block, ensuring a smooth transition during the positioning process. Through this structure, the positioning mechanism can accurately control the position of the fiber optic bundle under different operating conditions, avoiding fiber loosening or poor transmission caused by inaccurate fixing, thereby improving the overall stability and reliability of the patch panel.

[0029] Please see Figures 1-5 A fiber optic patch panel includes a patch panel body 1, on which a cable bundling mechanism is provided. The cable bundling mechanism includes a mounting plate 2, a mounting base 3, a cable bundling sleeve 4, sliding rods 5, sliders 6, compression springs 7, clamping plates 8, and a clamping mechanism. The mounting plate 2 is installed at the bottom of the patch panel body 1, the mounting base 3 is fixed on the mounting plate 2, the cable bundling sleeve 4 is installed on the mounting base 3, multiple sets of sliding rods 5 are distributed inside the cable bundling sleeve 4, the sliders 6 slide on multiple sets of sliding rods 5, multiple sets of compression springs 7 are respectively connected to the inner side of multiple sets of sliders 6, and the clamping plate 8 is provided with... Multiple sets of compression springs 7 are respectively installed at the bottom of multiple sets of compression springs 7. The clamping mechanism includes a transmission sleeve 9, a push ring 10, a rotating sleeve 11, a toothed ring 12, a screw 13, a gear 14 and a positioning mechanism. The transmission sleeve 9 slides on the outer wall of the cable harness sleeve 4. The push ring 10 is installed on the inner side of the transmission sleeve 9. The rotating sleeve 11 is rotatably installed on the outer wall of the cable harness sleeve 4. The toothed ring 12 is installed on the inner wall of the rotating sleeve 11. The screw 13 is provided with multiple sets of screws 13 that are rotatably installed on the outer side of the cable harness sleeve 4 and threadedly connected to the transmission sleeve 9. The gear 14 is installed on the top of the multiple sets of screws 13 and meshes with the toothed ring 12.

[0030] The positioning mechanism includes a connecting sleeve 15, positioning holes 16, support plates 17, positioning blocks 18, outer blocks 19, and tension springs 20. The connecting sleeve 15 is installed on the top surface of the rotating sleeve 11. Multiple sets of positioning holes 16 are provided on the outer wall of the connecting sleeve 15. Multiple sets of support plates 17 are provided on the outer wall of the cable harness sleeve 4. The positioning blocks 18 slide within the multiple sets of support plates 17. The outer blocks 19 are installed on the top of the multiple sets of positioning blocks 18. The tension springs 20 are connected to the inner side of the multiple sets of outer blocks 19 and are connected to the support plates 17.

[0031] Each set of sliding rods 5 has a limiting strip 21 on its outer wall. Each set of sliders 6 is slidably connected to the limiting strip 21. Through the cooperation between the limiting strip 21 and the slider 6, the sliding range of the slider 6 is limited, ensuring that the slider 6 can move smoothly within the predetermined track, avoiding excessive sliding or deviation of the slider 6, thereby improving the accuracy and stability of the wire harness device.

[0032] A compression spring 22 is installed inside the cable bundle sleeve 4, and a push pad 23 is installed at the bottom of the compression spring 22. The compression spring 22 provides continuous elastic pressure to ensure that the optical fiber is always in a tight state. The push pad 23 distributes pressure evenly to prevent excessive local compression of the optical fiber and improves the uniformity and stability of the optical fiber fixation.

[0033] Rubber strips 24 are provided on the inner side of multiple sets of clamping plates 8. There are multiple sets of rubber strips 24, which are distributed on the inner side of multiple sets of clamping plates 8. The rubber strips 24 increase the friction between the clamping plates 8 and the optical fiber, preventing the optical fiber from being damaged. At the same time, due to the elasticity of the rubber, the clamping plates can clamp the optical fiber more evenly, thereby improving the protection effect and fixing force of the optical fiber.

[0034] The cable bundle sleeve 4 is provided with guide rods 25. Multiple sets of guide rods 25 are provided and all are slidably connected to the push ring 10. The guide rods 25 can ensure that the push ring 10 slides smoothly in the cable bundle sleeve 4, reducing jamming or imbalance caused by irregular movement, thereby improving the smoothness and stability of the cable bundle device.

[0035] The tops of multiple positioning blocks 18 and the outer walls of positioning holes 16 are all set to be arc-shaped. The arc-shaped design allows the positioning blocks 18 to cooperate more smoothly with the positioning holes 16, reducing friction and preventing jamming, thereby ensuring higher positioning accuracy and improving the smoothness and stability of the positioning process.

[0036] Both ends of the cable tie 4 are rounded. The rounded corner design prevents the cable tie 4 from scratching or damaging the optical fiber or other components during use. At the same time, it makes the installation and removal of the cable tie 4 more convenient, improving the safety and comfort during use.

[0037] In this embodiment, when it is necessary to fix the cable, the cable is passed through the cable harness 4. The rotating sleeve 11 drives the gear ring 12 to rotate and mesh with multiple sets of gears 14, which in turn drives the multiple sets of gears 14 and screws 13 to rotate. The multiple sets of screws 13 are threadedly engaged with the transmission sleeve 9, which drives the transmission sleeve 9 and push ring 10 to slide. The push ring 10 pushes multiple sets of sliders 6 to slide along the slide rod 5. The sliding of the multiple sets of sliders 6 drives multiple sets of clamping plates 8 to clamp the outer wall of the cable and simultaneously pushes the push pad 23 and compresses the compression spring 22. When the cable is fixed, the push ring 10 disengages from the multiple sets of sliders 6. The elastic return of the compression spring 22 drives the push pad 23 to push the multiple sets of sliders 6 to return to their original position.

[0038] More specifically, as the rotating sleeve 11 rotates, it drives multiple sets of support plates 17 to rotate. The multiple sets of support plates 17 drive multiple sets of positioning blocks 18 to move within multiple sets of positioning holes 16. The multiple sets of positioning blocks 18 are guided to slide through the arc-shaped surface outside the positioning holes 16 and stretch the tension springs 20 respectively. When the multiple sets of positioning blocks 18 move to the next set of positioning holes 16, the multiple sets of pulling blocks 19 are pulled, and the outer blocks 19 push the positioning blocks 18 to engage in the positioning groove, thereby positioning the rotating sleeve 11 with a certain force.

[0039] In summary, when the overall equipment is in use or operation: when it is necessary to fix the cable, the cable is passed through the cable harness sleeve 4, the rotating sleeve 11 drives the gear ring 12 to rotate and mesh with multiple sets of gears 14, which in turn drives the multiple sets of gears 14 and screws 13 to rotate. The multiple sets of screws 13 are threadedly engaged with the transmission sleeve 9, which drives the transmission sleeve 9 to slide with the push ring 10. The push ring 10 pushes multiple sets of sliders 6 to slide along the slide rod 5. The sliding of the multiple sets of sliders 6 drives multiple sets of clamping plates 8 to clamp the outer wall of the cable and simultaneously pushes the push pad 23 and compresses the compression spring 22. When the cable is fixed, the push ring 10 disengages from the multiple sets of sliders 6, and the elastic return of the compression spring 22 drives the push pad 23 to push the multiple sets of sliders 6 to return to their original position.

[0040] As the rotating sleeve 11 rotates, it drives multiple sets of support plates 17 to rotate. The multiple sets of support plates 17 drive multiple sets of positioning blocks 18 to move within multiple sets of positioning holes 16. The multiple sets of positioning blocks 18 are guided to slide through the arc-shaped surface outside the positioning holes 16 and stretch the tension springs 20 respectively. When the multiple sets of positioning blocks 18 move to the next set of positioning holes 16, the multiple sets of pulling blocks 19 are pulled, and the outer blocks 19 push the positioning blocks 18 to engage in the positioning groove, thereby positioning the rotating sleeve 11 with a certain force.

For all the fixed connections mentioned above, welding is preferred.
