Description

Technical Field

[0001] This utility model relates to the technical field of patch panels, and in particular to a fiber optic patch panel. Background Technology

[0002] Fiber optic distribution frames 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 optical fiber communication systems, facilitating the connection, distribution, and scheduling of optical fiber lines. Currently, internal wiring is often bundled together using cable ties or similar methods. While this method is convenient, it requires tracing the bundled wiring during maintenance, which is inconvenient.

[0003] Chinese Patent Announcement No. CN210605116U, authorized on May 22, 2020, discloses an optical fiber distribution frame, including a distribution frame body. The frame body is characterized by: a plurality of connection boxes within the distribution box; an optical fiber entry unit box above the connection boxes; a cable routing box below the connection boxes; inlet coils and hanging posts on both sides of each connection box; an optical fiber entry slot at the top of the distribution frame body; optical fiber exit holes on both sides of the optical fiber entry slot; lifting lugs on both sides of the top of the distribution frame body; cable passage holes at the bottom of the distribution frame body; heat dissipation slots on both sides of the distribution frame body; and a door with an observation window. A drawback of this invention is that the optical fiber cables are bundled together, requiring disassembly for maintenance and making troubleshooting difficult. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies in which it is difficult to conduct targeted inspections of lines during maintenance, and provides a fiber optic distribution frame that can fix lines in batches or individually.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fiber optic patch panel includes a cabinet, placement racks, and a lifting assembly. The cabinet is mounted on the lifting assembly. Several evenly distributed placement racks are installed inside the cabinet. Cable management boards are installed on both sides of each placement rack. Fixing assemblies are installed on both sides of each placement rack, and the fixing assemblies correspond to the cable management boards.

[0006] The cabinet's interior contains several vertically evenly distributed racks for holding fiber optic boxes. After the fiber optic boxes are installed and secured, the fiber optic cables emerge from both sides and are organized by cable management boards. Each layer of cables is fixed to its respective cable management board, separating cables from different layers. Each layer's cables are also separated and organized on the cable management board. After separation, each layer's cables are secured by fixing components installed on its own rack to prevent cable movement. For maintenance, simply identify the corresponding fiber optic cable, open the corresponding fixing component, and the cable will pop out from the cable management board, enabling rapid cable organization. Furthermore, the cabinet is mounted on a lifting assembly, allowing it to be raised for protection, thus achieving the goal of securing cables in batches and individually.

[0007] Preferably, the placement rack has a U-shaped cross-section, and the cable management plate includes a horizontal plate, a curved plate, and a vertical plate. One end of the horizontal plate is connected to one side of the placement rack, and the curved plate has an arc-shaped cross-section. One end of the curved plate is connected to the other end of the horizontal plate, and the other end of the curved plate is connected to the vertical plate. The side of the placement rack is provided with several evenly distributed insertion holes, and the cable management plate is provided with several evenly distributed cable management grooves, with each cable management groove corresponding to one of the insertion holes. The placement rack has a U-shaped cross-section to prevent fiber optic boxes from getting stuck. Cable management plates are installed on both sides of the placement rack. The cable management plates are composed of a horizontal plate, a curved plate, and a vertical plate connected together. The horizontal plate is used to receive the fiber optic cables that pass through the sockets on the placement rack. After the cables enter the cable management groove on the horizontal plate, they enter the cable management groove on the curved plate. The curved plate bends into a quarter-circle arc shape, which can change the direction of the fiber optic plate, changing the fiber from the horizontal plate to the vertical plate. The fiber optic cables enter the cable management groove on the vertical plate. Since the sockets and cable management grooves correspond one-to-one, several fiber optic cables are fixed in different cable management grooves, separating and fixing the cables. This design can better separate the cables.

[0008] Preferably, the length of the horizontal plates decreases sequentially from top to bottom, and several evenly distributed cable trays are provided on both sides of the bottom surface of the cabinet, with each cable tray corresponding to a cable management tray. To facilitate maintenance by separating the cables on each layer, the length of the horizontal plates decreases sequentially from top to bottom. As the cables are pulled down from the vertical plates, they intersect. The cables exit the cabinet through the cable trays on the bottom surface and connect to external devices. Due to the decreasing length of the horizontal plates, corresponding fiber optic cables at the same vertical position exit the cabinet through the same cable tray, thus separating the cables horizontally and vertically for targeted maintenance. This design separates the cables on different layers.

[0009] Preferably, mounting plates are installed on both sides of the placement rack. The fixing assembly includes a screw and a fixing plate. The lower end of the screw passes through the mounting plate and is positioned at the lower end of the mounting plate. The screw is threadedly connected to the mounting plate. A handwheel is installed on the upper end of the screw, and the lower end of the screw is rotatably connected to the fixing plate. The fixing plate corresponds to the horizontal plate of the cable management plate. To prevent the fiber optic cable from moving within the cable management groove, a fixing assembly is installed on the placement rack to secure the fiber optic cable. Fixing assemblies are installed on both sides of the placement rack. The screw of the fixing assembly is threadedly connected to the mounting plate installed on the side of the placement rack. The extension length of the lower end of the screw is controlled by the rotation of the screw, thereby causing the fixing plate at the lower end to press against the cable management plate, thus securing the fiber optic cable within the cable management groove. To prevent the fixing plate from rotating with the screw, the fixing plate is rotatably connected to the screw, ensuring that the fixing plate does not rotate with the screw. This design effectively secures the fiber optic cable.

[0010] Preferably, guide rods are installed on both sides of the horizontal plate. One end of each guide rod is connected to the horizontal plate, and the other end passes through the fixed plate and is positioned above it. The fixed plate is rotatably connected to the screw. However, without external force, the fixed rods will inevitably deflect at a certain angle. The deflected fixed plate cannot correspond well with the horizontal plate. Therefore, to ensure that the fixed plate only moves up and down, guide rods are installed on both sides of the horizontal plate. The upper end of the guide rod passes through the fixed plate, and the fixed plate can only move up and down along the guide rods. This design can restrict the rotation of the fixed plate.

[0011] Preferably, the lifting assembly includes a support base, a pneumatic cylinder, a sleeve, and a connecting rod. The support base is equipped with several evenly distributed sleeves. Several connecting rods are provided, each corresponding to one of the sleeves. One end of each connecting rod is placed inside a sleeve and slidably connected to it. The other end of each connecting rod is connected to the bottom surface of the cabinet. Several evenly distributed connecting holes are provided on each connecting rod. A fixing hole is provided on each sleeve, and the fixing hole matches the connecting hole. An insertion rod is provided on each sleeve, and one end of the insertion rod passes through the fixing hole and the connecting hole and is placed on the other side of the sleeve. To protect the cabinet, reduce the possibility of moisture getting to the bottom, and facilitate the fiber optic cable exiting from the bottom, the pneumatic cylinder lifts the cabinet by raising its pneumatic end. During this lifting process, a connecting rod installed on the bottom of the cabinet rises within a sleeve installed on the support base. Two connecting rods are installed on each side of the cabinet to ensure its stability. After the pneumatic cylinder lifts the cabinet to a certain height, a connecting hole on the connecting rod aligns with a fixing hole on the sleeve. Then, an insert rod is passed through the fixing hole and the connecting hole to fix the sleeve and the connecting rod together, thus fixing the cabinet's lifting height. This design allows for increased cabinet height.

[0012] The beneficial effects of this utility model are: it can fix the lines in batches and individually, it can better separate the lines, it can separate lines of different layers, it can fix optical fiber lines, it can restrict the rotation of the fixing plate, and it can increase the height of the cabinet.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 In one embodiment, a fiber optic distribution frame includes a cabinet 1, a placement rack 2, and a lifting assembly 3. The cabinet 1 is mounted on the lifting assembly 3. Several evenly distributed placement racks 2 are installed inside the cabinet 1. Cable management plates 4 are installed on both sides of the placement racks 2. Fixing assemblies 5 are installed on both sides of the placement racks 2, and the fixing assemblies 5 correspond to the cable management plates 4.

[0017] like Figure 2 As shown, the cross-sectional shape of the placement rack 2 is U-shaped. The cable management plate 4 includes a horizontal plate 41, a curved plate 42, and a vertical plate 43. One end of the horizontal plate 41 is connected to one side of the placement rack 2. The cross-sectional shape of the curved plate 42 is arc-shaped. One end of the curved plate 42 is connected to the other end of the horizontal plate 41, and the other end of the curved plate 42 is connected to the vertical plate 43. The side of the placement rack 2 is provided with several evenly distributed insertion holes 21. The cable management plate 4 is provided with several evenly distributed cable management grooves 44, and the cable management grooves 44 correspond one-to-one with the insertion holes 21.

[0018] The length of the horizontal plate 41 decreases from top to bottom. Several evenly distributed cable trays 11 are provided on both sides of the bottom surface of the cabinet 1. The cable trays 11 correspond one-to-one with the cable management trays 44.

[0019] Mounting plates 22 are installed on both sides of the mounting rack 2. The fixing component 5 includes a screw 51 and a fixing plate 52. The lower end of the screw 51 passes through the mounting plate 22 and is placed at the lower end of the mounting plate 22. The screw 51 is threadedly connected to the mounting plate 22. A handwheel is installed on the upper end of the screw 51. The lower end of the screw 51 is rotatably connected to the fixing plate 52. The fixing plate 52 corresponds to the horizontal plate 41 of the cable management plate 4.

[0020] Guide rods 45 are installed on both sides of the horizontal plate 41. One end of the guide rod 45 is connected to the horizontal plate 41, and the other end of the guide rod 45 is placed above the fixed plate 52 after penetrating the fixed plate 52.

[0021] like Figure 3 , Figure 4 As shown, the lifting assembly 3 includes a support base 31, a pneumatic cylinder 32, a sleeve 33, and a connecting rod 34. The support base 31 is equipped with several evenly distributed sleeves 33. Several connecting rods 34 are provided, each corresponding to one of the sleeves 33. One end of the connecting rod 34 is placed inside the sleeve 33 and is slidably connected to the sleeve 33. The other end of the connecting rod 34 is connected to the bottom surface of the cabinet 1. Several evenly distributed connecting holes 35 are provided on the connecting rod 34. The sleeve 33 is provided with a fixing hole 36, which matches the connecting hole 35. The sleeve 33 is provided with an insertion rod 37, one end of which passes through the fixing hole 36 and the connecting hole 35 and is placed on the other side of the sleeve 33.

[0022] In use, the fiber optic boxes are placed sequentially on the placement rack 2. After placement on the rack 2, the fiber optic cables are passed through the socket 21 and positioned above the cable management plate 4. The fiber optic cables are then pressed into the corresponding cable management slots 44, with each slot 44 on the cable management plate 4 containing a fiber optic cable. After the fiber optic cables in each layer are separated, they are pulled downwards from the vertical plate 43 after the bending plate 42 changes direction, and then pulled out of the cabinet 1 from the cable outlet 11 on the bottom of the cabinet to connect with external equipment. After the fiber optic cables are connected, the handwheel 53 is turned, causing the screw 51 to rotate on the mounting plate 22. This causes the fixing plate 52 to move downwards along the guide rod 45, fixing the fixing plate 52 within the cable management slots 44 and ensuring the position of the fiber optic cables.

[0023] When the corresponding fiber optic cable needs to be repaired, simply release the fixing plate 52 from the fiber optic cable and then pull it out from the corresponding cable tray 44. When installing the cabinet 1, after lifting the cabinet 1 with a pneumatic cylinder, insert the insertion rod 37 into the fixing hole 52 on the sleeve 33 and then insert it into the connecting hole 35 to fix the position of the connecting rod 34 and the sleeve 33, thus fixing the height of the cabinet 1.
