Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to a jumper cable management technology, and specifically to an optical fiber jumper cable management frame. Background Art

[0002] Fiber optic patch cords are used as jumpers from devices to fiber optic cabling links. They usually contain two fiber optic cables with fiber optic connectors installed. These two connectors can achieve fast and pluggable connections between optical fibers. Fiber optic patch cords are used to connect optical transceivers, switches, routers, optical distribution frames (ODFs) and other devices to achieve optical signal transmission, providing a flexible and reliable fiber optic connection solution for signal transmission in fiber optic networks. They are mainly used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission and local area networks.

[0003] In the computer room, tools such as optical cable reels, cable management racks / troughs, and cable troughs are usually configured for intensive organization and management, which is conducive to the neat and beautiful layout of optical fiber jumpers in the computer room, convenient for subsequent maintenance and management, reducing the loss of optical fiber jumpers, clarifying the connection relationship and direction, and avoiding external force damage such as optical fiber squeezing caused by excessive length, too shortness, and irregular bending radius of optical fiber jumpers, ensuring efficient and stable transmission of optical signals. For example, in the design of the optical fiber jumper cable management rack, a certain diameter winding rack is used for optical fiber winding. When the optical fiber jumper is connected to the device, the excess length of optical fiber is wound on the winding rack. The diameter size of the existing winding rack is usually fixed. When the optical fiber is wound for the last circle, the optical fiber often cannot be wound around a full circle. If it is wound one circle less, the remaining length of optical fiber is longer. At the cable management rack, the optical fiber layout is still chaotic, which hinders maintenance personnel from quickly locating problems and repairing and maintaining. Utility Model Content

[0004] In view of the technical problems existing in the prior art of managing optical fiber jumpers, the first aspect of the utility model provides an optical fiber jumper management rack, comprising:

[0005] A tray, wherein the tray is configured as a rectangular shell with an opening at the top;

[0006] A top cover, detachably connected to the open end of the tray, for closing the open end of the tray;

[0007] A plurality of fixed winding frames for winding optical fiber jumpers are arranged inside the tray, and a first cover plate for limiting the position of the optical fiber is arranged on the top of the fixed winding frame;

[0008] Wherein, the first cover plate is provided with two symmetrically arranged arc-shaped winding frames with the same diameter, and the arc-shaped winding frames are configured to be able to slide along the length direction of the fixed winding frame so that the distance between the two arc-shaped winding frames can be adjusted;

[0009] A plurality of threading openings are arranged around the first cover plate so that the optical fiber jumper wound on the fixed winding frame can be introduced into the arc-shaped winding frame.

[0010] As an optional implementation, sliders are provided at both ends of the arc-shaped winding frame, and sliding grooves corresponding to the sliders are opened on both sides of the first cover plate, and the sliders are slidably connected to the sliding grooves.

[0011] As an optional implementation, the slide groove is configured to have a damping force when the slider slides in the slide groove.

[0012] As an optional implementation, the height of the fixed winding rack is 3.0-5.0 cm.

[0016] As an optional implementation, the socket and the top of the connecting column are both configured as rectangular structures.

[0017] As an optional embodiment, a rubber strip is provided around the inner wall of the socket. When the connecting column is inserted into the socket, the rubber strip is squeezed, which can increase the friction between the connecting column and the inner wall of the socket.

[0026] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0027] Combination Figure 1-Figure 3 As shown, the optical fiber jumper cable management frame of the embodiment of the utility model includes a tray 1, a top cover 2, a fixed winding frame 3 and a first cover plate 31.

[0028] The tray 1 is configured as a rectangular shell with an opening at the top, and the top cover 2 is detachably connected to the open end of the tray 1 for closing the open end of the tray 1. A plurality of fixed winding frames 3 for winding optical fiber jumpers are provided inside the tray 1. By opening the top cover 2, the optical fiber jumpers are introduced into the tray 1 and wound on the fixed winding frames 3.

[0029] Furthermore, cable arrangement openings 101 are provided on both sides of the tray 1 , so that the optical fibers can be introduced into and led out from the sides of the tray 1 .

[0030] Furthermore, a first cover plate 31 is provided on the top of the fixed winding frame 3 , which can limit the vertical position of the optical fiber wound on the fixed winding frame 3 to prevent the optical fiber from moving upward and detaching from the fixed winding frame 3 .

[0031] In a specific embodiment, bolt holes are provided on the top cover 2, and corresponding threaded holes are provided on the tray 1. The top cover 2 is fixed to the tray 1 by bolts, and is easy to assemble and disassemble.

[0032] Since the diameter of the existing winding frame is fixed, the optical fiber often cannot be wound fully during the last circle. If it is wound one circle less, the remaining length of the optical fiber is longer, and the optical fiber will still be in a mess at the cable management frame.

[0033] Combination Figure 2 and Figure 3 As shown, two symmetrically arranged arc-shaped winding frames 33 with the same diameter are provided on the first cover plate 31, and the arc-shaped winding frames 33 are configured to be able to slide along the length direction of the fixed winding frame 3 so that the distance between the two arc-shaped winding frames 33 can be adjusted. When the distance between the two arc-shaped winding frames 33 is smaller, the length of the optical fiber wound around the two arc-shaped winding frames 33 is smaller.

[0034] When the optical fiber is wound on the fixed winding frame 3 to the last circle, if the optical fiber cannot be wound in a full circle, if it is wound one circle less, the remaining length of the optical fiber is long, the optical fiber is introduced upward to the arc winding frame 33, and at the same time, the distance between the two arc winding frames 33 is reduced so that the two arc winding frames 33 can reel in the remaining optical fiber jumpers without causing the optical fiber jumper to be insufficient in length or excessive in length, thereby improving the flexibility of reeling and arranging the cables and making the cable arrangement of the optical fiber jumpers neater.

[0035] Furthermore, a plurality of threading openings 311 are provided around the first cover plate 31, so that the optical fiber jumper wound on the fixed winding frame 3 can pass through the threading openings 311 and be introduced into the arc winding frame 33, thereby reducing the obstruction of the optical fiber jumper by the first cover plate 31 and improving the neatness of the optical fiber jumper wiring.

[0036] In a specific embodiment, sliders 331 are provided at both ends of the arc-shaped winding frame 33, and sliding grooves 312 corresponding to the sliders 331 are opened on both sides of the first cover plate 31. The sliders 331 are slidably connected to the sliding grooves 312. Through the cooperation of the sliders 331 and the sliding grooves 312, the sliding of the arc-shaped winding frame 33 is limited, so that the two arc-shaped winding frames 33 can only slide in symmetrical directions, thereby preventing the arc-shaped winding frames 33 from deviating.

[0037] Furthermore, the slide groove 312 is configured to have a damping force when the slider 331 slides in the slide groove 312, so that when the arc winding frame 33 slides to any position, there is sufficient damping force between the slider 331 and the slide groove 312, so that the arc winding frame 33 stops at the current position and maintains the spacing, so that the arc winding frame 33 will not move when the optical fiber is wound.

[0038] In a specific embodiment, a rubber strip is disposed on the inner wall of the slide groove 312 , and when the slider 331 is in the slide groove 312 , the rubber strip is squeezed to increase the friction force, thereby applying a damping force to the slider 331 .

[0039] Since the optical fiber jumper is mainly wound on the fixed winding frame 3, in an optional embodiment, the height of the fixed winding frame 3 is 3.0-5.0 cm, preferably the height of the fixed winding frame 3 is 5.0, the height of the arc winding frame 33 is 1.0-3.0 cm, preferably the height of the arc winding frame 33 is 1.0 cm, the higher height of the fixed winding frame 3 can wind up more optical fiber, and the lower height of the arc winding frame 33 can reduce the overall height of the device and reduce the space occupied by the device.

[0040] Combination Figure 2 As shown, a second cover plate 34 is provided above the arc-shaped winding frame 33 to limit the vertical position of the optical fiber wound on the arc-shaped winding frame 33 to prevent the optical fiber from falling off.

[0041] In a specific embodiment, a connecting column 32 is fixed at the center position of the top surface of the first cover plate 31, and a socket 341 is opened at the center position of the second cover plate 34. The second cover plate 34 is connected to the top of the connecting column 32 through the socket 341. The connecting column 32 serves to connect and support the first cover plate 31, and the connecting column 32 located at the center position of the first cover plate 31 will not affect the movement of the arc winding frame 33 and the winding of the optical fiber.

[0042] Furthermore, a rubber strip is provided around the inner wall of the socket 341. When the connecting column 32 is inserted into the socket 341, the rubber strip is squeezed, which can increase the friction between the connecting column 32 and the inner wall of the socket 341, thereby preventing the second cover plate 34 from being detached by the optical fiber jumper.

[0043] In an optional embodiment, the tops of the socket 341 and the connecting column 32 are both configured as rectangular structures, and when the socket 341 and the connecting column 32 are connected, they can self-limit to prevent the second cover plate 34 from rotating.

[0044] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
