Description

Technical Field

[0001] This utility model relates to the field of patch panel technology, and in particular to an optical fiber patch panel. Background Technology

[0002] Fiber optic distribution frames (Fiber optic patch panels) are wiring connection devices between optical cables and optical communication equipment, or between optical communication equipment. They are used for termination and distribution of backbone optical cables at the central office in fiber optic communication systems, facilitating the connection, distribution, and scheduling of fiber optic lines. With increasing network integration, hybrid optical-digital distribution frames integrating ODF, DDF, and power distribution units have emerged, suitable for small and medium-sized wiring systems in fiber-to-the-home (FTTH), fiber-to-the-building (FTTH), remote modules, and wireless base stations.

[0003] For example, Chinese utility model patent (CN222599920U) discloses a multi-row fiber optic distribution frame, which states: "This utility model realizes the fiber optic cable bundling through a cable bundling mechanism, so that the cable bundling disc can be adjusted according to the fiber optic length inside the distribution frame. The assembly mechanism realizes the assembly of the coupler group, so that some devices can install and remove the coupler group, which facilitates the connection operation of the fiber optic cable and improves the convenience and adjustability of the device." It also states: "Existing devices mainly pass the optical cable into the distribution frame and connect the fiber optic cable to the coupler in sequence, making it difficult for some devices to adjust according to the fiber optic length inside the distribution frame. This makes it difficult for some devices to limit and bind the fiber optic cable. At the same time, some devices mainly fix the coupler group on the front side of the box, making it difficult for some devices to quickly install and remove the coupler group. This makes it difficult for the fiber optic cable to be quickly connected to the coupler, reducing the working efficiency and practicality of the device."

[0004] In summary, existing technologies utilize cable trays to bundle optical fibers. However, this method presents the following technical problems: After the optical fibers are wrapped around the cable tray, they generally need to be secured with cable ties or tape. Since cable ties and tape are disposable items, they must be removed when disassembling the optical fibers, resulting in material waste. Therefore, this application proposes an optical fiber distribution frame to address the technical problems mentioned in the aforementioned patents and provide a new technical solution. Utility Model Content

[0005] Therefore, it is necessary to provide a fiber optic distribution frame to address the aforementioned technical problems. This frame can constrain the optical fibers wound around the outside of the cable tray using a moving component and a constraint component. This reduces the need for operators to prepare disposable materials such as cable ties or tape to bind the optical fibers, thus reducing material waste. The friction component can rotate the U-shaped rod that is not inserted into the cable tray to a position that does not affect the winding of the optical fibers on the cable tray, and keep the U-shaped rod in that position without requiring continuous manual support from the operator, thereby improving the ease of operation of the device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A fiber optic patch panel, which is used in patch panels.

[0008] The fiber optic distribution frame specifically includes:

[0009] The housing has a top cover fixedly installed on its top, a coupler assembly fixedly installed on its inner wall, two wire harness mechanisms on its inner wall, and two limiting mechanisms on its surface.

[0010] The wire harnessing mechanism includes a wire harnessing disc, a moving component, a constraining component, and a friction component. The wire harnessing disc is fixedly connected to the lower surface of the inner wall of the housing. Two moving components, a constraining component, and a friction component are respectively arranged on the wire harnessing disc.

[0011] In a preferred embodiment of the fiber optic distribution frame provided by this utility model, the movable component includes a T-shaped block, the inner wall of the cable tray is slidably connected to the T-shaped block, the inner wall of the T-shaped block is threadedly connected to a connecting screw, and the end of the connecting screw away from the T-shaped block is fixedly connected to an anti-slip disc.

[0012] In a preferred embodiment of the fiber optic distribution frame provided by this utility model, the constraint component includes a rotating seat, the inner wall of the T-shaped block is rotatably connected to the rotating seat, the outer wall of the rotating seat is fixedly connected to a U-shaped rod, and the U-shaped rod is movably inserted into the cable tray.

[0013] In a preferred embodiment of the fiber optic distribution frame provided by this utility model, the friction assembly includes a friction pad, the inner wall of the T-shaped block and the left and right sides are respectively fixedly connected to the friction pad, and the rotating seat is slidably connected to the outer wall of the friction pad.

[0014] In a preferred embodiment of the fiber optic distribution frame provided by this utility model, the limiting mechanism includes a cable inlet, the outer shell has multiple cable inlets, a support frame is fixedly connected to the lower surface of the inner wall of the outer shell, and multiple compression components are provided on the support frame.

[0015] In a preferred embodiment of the fiber optic distribution frame provided by this utility model, the extrusion assembly includes an adjusting screw, the inner wall of the support frame is threadedly connected to the adjusting screw, the bottom end of the adjusting screw is rotatably connected to an extrusion claw, the lower surface of the inner wall of the outer shell is fixedly connected to a limiting seat, and the extrusion claw is slidably connected to the outer wall of the limiting seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The fiber optic distribution frame provided by this utility model can constrain the optical fibers wound around the outside of the cable tray through the moving component and the constraining component. This reduces the need for operators to prepare disposable materials such as cable ties or tape to bind the optical fibers, thus reducing material waste. Through the friction component, the U-shaped rod that is not inserted into the cable tray can be rotated to a position that does not affect the winding of the optical fibers on the cable tray, and the U-shaped rod is kept in that position without the need for the operator to hold it continuously, which improves the convenience of the device operation.

[0018] The fiber optic distribution frame provided by this utility model uses a limiting mechanism to compress and restrict the fiber optic group, thereby fixing and restricting the fiber optic group. This reduces the disorder or loosening of the fiber optic wiring inside the housing caused by the movement of the corresponding fiber due to external pulling of the optical cable, thus improving the stability of the device. Furthermore, since the limiting mechanism can restrict various fiber optic groups with different overall thicknesses, it improves the practicality of the device. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background art, in the use of the above-mentioned device, after the light is wrapped around the outside of the cable tray, it is generally necessary to restrict and fix the optical fiber with cable ties or tape. However, cable ties or tape are disposable items, and they need to be removed when the optical fiber is disassembled, which results in material waste.

[0030] To solve this technical problem, this utility model provides a fiber optic patch panel, which is applied to patch panels.

[0031] For details, please refer to Figures 1-3 Fiber optic distribution frames specifically include:

[0032] The outer casing 1 has a top cover 2 fixedly installed on its top, a coupler assembly 3 fixedly installed on its inner wall, two wire harness mechanisms 4 on its inner wall, and two limiting mechanisms 5 on its surface.

[0033] The wire harnessing mechanism 4 includes a wire harnessing disc 6, a moving component, a constraining component, and a friction component. The wire harnessing disc 6 is fixedly connected to the lower inner wall of the housing 1. Two moving components, a constraining component, and a friction component are respectively provided on the wire harnessing disc 6.

[0034] The fiber optic distribution frame provided by this utility model can constrain the optical fibers wound around the outside of the cable tray 6 through the moving component and the constraining component. This reduces the need for operators to prepare disposable materials such as cable ties or tape to bind the optical fibers, thus reducing material waste. Through the friction component, the U-shaped rod 11 that is not inserted into the cable tray 6 can be rotated to a position that does not affect the winding of the optical fibers on the cable tray 6, and the U-shaped rod 11 can be kept in that position without the need for the operator to hold it continuously, thus improving the convenience of device operation.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figures 1-5 A fiber optic distribution frame, comprising:

[0038] The outer casing 1 has a top cover 2 fixedly installed on its top, a coupler assembly 3 fixedly installed on its inner wall, two wire harness mechanisms 4 on its inner wall, and two limiting mechanisms 5 on its surface.

[0039] The cable bundling mechanism 4 includes a cable bundling disk 6, a moving component, a constraining component, and a friction component. The cable bundling disk 6 is fixedly connected to the lower surface of the inner wall of the housing 1. Two moving components, a constraining component, and a friction component are respectively provided on the cable bundling disk 6. The cable bundling mechanism 4 can restrict the wound optical fiber.

[0040] The moving component includes a T-shaped block 7, which is slidably connected to the inner wall of the cable tray 6. A connecting screw 8 is threadedly connected to the inner wall of the T-shaped block 7. An anti-slip plate 9 is fixedly connected to the end of the connecting screw 8 away from the T-shaped block 7. The moving component can adjust the position of the U-shaped rod 11 according to the actual thickness of the optical fiber wound on the outside of the cable tray 6, so that the U-shaped rod 11 and the cable tray 6 can form a space that adapts to the current thickness of the optical fiber.

[0041] The constraint assembly includes a rotating seat 10, which is rotatably connected to the inner wall of the T-shaped block 7. A U-shaped rod 11 is fixedly connected to the outer wall of the rotating seat 10. The U-shaped rod 11 is movably inserted into the cable tray 6. The U-shaped rod 11 can be reused to constrain the optical fiber and reduce the waste of disposable materials.

[0042] The friction assembly includes a friction pad 12, and friction pads 12 are fixedly connected to the inner wall of the T-shaped block 7 on the left and right sides respectively. The rotating seat 10 is slidably connected to the outer wall of the friction pad 12. The friction between the rotating seat 10 and the friction pad 12 is sufficient to allow the operator to rotate the rotating seat 10 to any angle and then release the rotating seat 10 to keep the rotating seat 10 at the current angle.

[0043] With the above structural design, before the optical fiber is wound around the two cable trays 6, rotating the anti-slip disc 9 causes the connecting screw 8 to rotate inside the corresponding T-shaped block 7, causing the anti-slip disc 9 to leave the corresponding cable tray 6. Then, the anti-slip disc 9 can be moved to slide the T-shaped block 7 inside the cable tray 6, allowing the U-shaped rod 11 to leave the cable tray 6. Subsequently, the U-shaped rod 11 can be pulled, causing the rotating seat 10 to rotate on the inner wall of the T-shaped block 7. After pulling the U-shaped rod 11 to a position that does not affect the winding of the optical fiber onto the cable tray 6, the rotating seat 10 is released. The friction between the rotating seat 10 and the friction pad 12 keeps the U-shaped rod 11 in place. Holding the optical fiber in the current position, the light can then be wound around the outside of the two cable trays 6. The U-shaped rod 11 can then be pulled to rotate the rotating seat 10 to a horizontal position, aligning the U-shaped rod 11 with the slot on the cable tray 6. The T-shaped block 7 can then be slid to insert the U-shaped rod 11 into the cable tray 6. The insertion position of the U-shaped rod 11 into the cable tray 6 can be adjusted according to the overall thickness of the wound optical fiber. The anti-slip plate 9 can then be rotated in the opposite direction to rotate the connecting screw 8 into the T-shaped block 7, so that the anti-slip plate 9 is pressed tightly against the outside of the cable tray 6. The friction between the anti-slip plate 9 and the cable tray 6 restricts the sliding of the T-shaped block 7 within the cable tray 6.

[0044] Example 2:

[0045] The fiber optic distribution frame provided in Example 1 is further optimized, specifically, as follows: Figure 3 and Figure 6 As shown, the limiting mechanism 5 includes an inlet 13. Multiple inlets 13 are provided on the outer shell 1. A support frame 14 is fixedly connected to the lower surface of the inner wall of the outer shell 1. Multiple extrusion components are provided on the support frame 14. There is an extrusion component corresponding to the position of the inlet 13. It is also worth mentioning that the specific size of the limiting mechanism 5 is set according to the actual range of the total thickness of the optical fiber that can be accommodated, so that the minimum thickness of the optical fiber that can be accommodated can be extruded and fixed by the minimum space enclosed by the extrusion claw 17 and the limiting seat 15, and the maximum thickness of the optical fiber can be extruded and fixed by the maximum space enclosed by the extrusion claw 17 and the limiting seat 15.

[0046] The extrusion assembly includes an adjusting screw 16, which is threaded onto the inner wall of the support frame 14. An extrusion claw 17 is rotatably connected to the bottom end of the adjusting screw 16. A limiting seat 15 is fixedly connected to the lower surface of the inner wall of the outer shell 1. The extrusion claw 17 is slidably connected to the outer wall of the limiting seat 15. The extrusion assembly can extrude and limit the optical fiber group in the corresponding optical cable. After the optical fiber group is unfolded, it can adapt to the space enclosed by the limiting seat 15 and the extrusion claw 17. By extruding the optical fiber with the extrusion claw 17 and the limiting seat 15, the movement of the optical fiber relative to the support frame 14 can be limited. Due to the limitation of the support frame 14, the extrusion claw 17 always slides on the limiting seat 15 during the process of adjusting the size of the space enclosed by the extrusion claw 17 and the limiting seat 15.

[0047] With the above structural design, after the optical cable passes through the inlet 13, the corresponding optical fiber group passes through the space enclosed by the corresponding limiting seat 15 and the squeezing claw 17. At this time, the space between the limiting seat 15 and the squeezing claw 17 should be adjusted to the maximum. Then, when it is necessary to restrict the optical fiber group, rotate the corresponding adjusting screw 16, and under the restriction of the limiting seat 15, the squeezing claw 17 can slide downward, thereby squeezing and restricting the optical fiber group.
