Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to a cable management ring and a patch panel. Background Technology

[0002] In the current field of optical fiber communication technology, optical fiber distribution frames are essential equipment for realizing optical fiber communication connections. Traditional optical fiber distribution frames typically consist of a distribution frame body, fiber optic boxes, trays, etc. Among them, cable management rings are key components for fiber organization, mainly used to manage and fix optical fibers in an orderly manner to avoid fiber tangling and mess, and to ensure the stability and reliability of optical fiber transmission.

[0003] Cable management rings in related technologies are typically fixed in place, such as by screws or double-sided adhesive, to the patch panel. This method makes adjusting the direction of the cable management rings extremely cumbersome. When the fiber optic cable routing needs to be readjusted, the adhesive backing or screw holes must be repositioned to adjust the installation direction of the cable management ring, thereby adjusting its cable routing direction to meet the needs of different routing directions on site. This process is not only time-consuming and labor-intensive, but also prone to damage to the cable management ring due to improper installation, increasing maintenance costs and time. Utility Model Content

[0004] The main purpose of this invention is to propose a cable management ring and a patch panel, which aims to solve the technical problem of low cable management efficiency of cable management rings in related technologies.

[0005] To achieve the above objectives, the present invention proposes a cable management ring, which includes:

[0006] The base has a cable management channel for the entry and exit of optical fibers;

[0007] A cover plate is provided on the opening of the cable management groove and is rotatably connected to the base; when the cover plate rotates relative to the base, it can cover or expose the opening of the cable management groove.

[0008] In one embodiment, the cover plate is provided with a rotating shaft, the base is provided with a shaft hole, the rotating shaft is rotatably connected in the shaft hole, the axial direction of the rotating shaft is perpendicular to the extension direction of the base, and the axial direction of the rotating shaft is perpendicular to the rotation direction of the cover plate.

[0009] In one embodiment, a positioning pin is provided on one side of the cover plate, and an insertion hole is provided on the side wall of the base;

[0010] When the cover plate is placed over the opening of the cable management groove, the positioning pin is slidably limited within the insertion hole.

[0011] In one embodiment, the base has two guide sections and a straight section on one side wall near the free end of the cover plate. The straight section has the insertion hole, and the two guide sections are inclined in opposite directions.

[0012] In one embodiment, the rotating shaft is polygonal, the wall of the rotating shaft has a rounded transition, and the shape of the rotating shaft is adapted to the shape of the shaft hole.

[0013] In one embodiment, the end of the rotating shaft away from the cover plate is provided with an elastic buckle. The elastic buckle includes two spaced elastic locking arms, each of which passes through the shaft hole and abuts against the periphery of the shaft hole facing away from the base.

[0014] In one embodiment, the side of the base facing away from the cable management groove is recessed in the direction of the opening of the cable management groove to form a groove.

[0015] In one embodiment, a mating groove is formed at one end of the base, the mating groove is spaced apart from the cable management groove, and the mating groove is configured to hinge with the protective cover of the patch panel;

[0016] And / or, the base is further provided with a snap-fit ​​groove, which is spaced apart from the cable management groove, and the snap-fit ​​groove is configured to snap into the protective cover of the patch panel.

[0017] This utility model also proposes a patch panel, the patch panel comprising:

[0018] As described above, the cable management loop;

[0019] The tray is connected to the cable management ring.

[0020] In one embodiment, the tray is provided with a protective cover, one end of which is hinged to the cable management ring, and the other end of which is snapped into the cable management ring.

[0021] This invention provides an orderly channel for fiber optic cables by using a base with cable management grooves and a cover plate that can rotate relative to the base. This not only improves the neatness and aesthetics of the cabling but also enhances the flexibility and practicality of the cable management ring through the rotatable design of the cover plate. The cable management grooves provide a dedicated channel for fiber optic cables, allowing them to enter and exit the cable management rings in an orderly manner, avoiding tangled cable management and thus improving the neatness and aesthetics of the fiber optic cabling. The cover plate and base are connected by a rotating mechanism, allowing the cover plate to rotate freely relative to the base within a certain angle range. When it is necessary to adjust the direction of the fiber optic cable, simply rotate the cover plate to the appropriate position and store the fiber in the cable management groove, eliminating the need to disassemble and reassemble the cable management ring from the patch panel. This greatly simplifies the operation process and improves the flexibility and efficiency of fiber optic cabling. Furthermore, since the cover plate is positioned over the opening of the cable management groove when stationary, and fully exposes the groove when the fiber optic cable direction needs to be adjusted, the fiber can be stored in the groove in one go, improving cable management efficiency. This rotating cover design facilitates the insertion and removal of optical fibers, further enhancing the ease of use of the cable management ring and effectively solving problems such as complex direction adjustment, insufficient flexibility, and inconvenient installation and maintenance of existing cable management rings.

[0041] This utility model proposes a wire management ring 100.

[0042] Please see Figures 1 to 10 In one embodiment of the present invention, the cable management ring 100 includes a base 1 and a cover plate 2. The base 1 has a cable management groove 11 for optical fiber to enter and exit. The cover plate 2 covers the groove opening of the cable management groove 11 and is rotatably connected to the base 1. When the cover plate 2 rotates relative to the base 1, it can cover or expose the groove opening of the cable management groove 11.

[0043] In this embodiment, it should be noted that the cable management ring 100 is used to manage and fix the fiber optic cables of the fiber optic distribution frame 200 in an orderly manner, so as to avoid fiber optic tangling and mess, and ensure the stability and reliability of fiber optic transmission. Combined with Figure 1The base 1 has a cable management groove 11, which provides an orderly channel for optical fibers, allowing them to be neatly placed inside and preventing tangling and interference. The base 1 and the cover plate 2 are connected by a rotatable joint, with the base 1 providing the structural support for the installation and rotation of the cover plate 2. When the cover plate 2 is closed onto the opening of the cable management groove 11 on the base 1, the base 1 and the cover plate 2 together form a closed space, enclosing the optical fibers within the cable management groove 11 and thus protecting them. It is understood that the cover plate 2 can rotate relative to the base 1, not only horizontally but also vertically. In one embodiment, when the cover plate 2 can rotate up and down relative to the base 1, that is, when the cover plate 2 can rotate relative to the base 1, the cover plate 2 and the base 1 are connected by a hinge. When the cover plate 2 is placed over the opening of the cable management groove 11, the connection point between the cover plate 2 and the base 1 is set at 90 degrees; when the cover plate 2 is no longer placed over the opening of the cable management groove 11, the connection point between the cover plate 2 and the base 1 is on the same horizontal line. The implementation method for the cover plate 2 to rotate left and right relative to the base 1 is described in the next embodiment. It is understood that the material of the cable management ring 100 includes, but is not limited to, metal, plastic, etc., and is not limited here.

[0044] The technical solution of this utility model, by setting a base 1 with cable management grooves 11 and a cover 2 that can rotate relative to the base 1, not only provides an orderly channel for optical fiber cables, improving the neatness and aesthetics of the cabling, but also enhances the flexibility and practicality of the cable management ring 100 through the rotatable design of the cover 2. The cable management grooves 11 provide a dedicated channel for optical fiber cables, allowing them to enter and exit the cable management ring 100 in an orderly manner, avoiding tangled optical fiber cables and thus improving the neatness and aesthetics of the optical fiber cabling. The cover 2 and the base 1 are connected by a rotatable method, which allows the cover 2 to rotate freely relative to the base 1 within a certain angle range, thereby adapting to the needs of optical fiber cabling in different directions. When it is necessary to adjust the direction of the optical fiber, simply rotate the cover 2 to the appropriate position and store the optical fiber in the cable management grooves 11, without having to disassemble and reassemble the cable management ring 100 from the patch panel 200, greatly simplifying the operation process and improving the flexibility and efficiency of optical fiber cabling. Meanwhile, since the cover plate 2 is positioned over the opening of the cable management groove 11 when not rotated, and when the fiber routing direction needs to be adjusted, rotating the cover plate 2 fully exposes the opening of the cable management groove 11, allowing the fiber to be stored in the cable management groove 11 in one go, thus improving cable management efficiency. This rotating cover plate 2 design facilitates the insertion and removal of fiber, further enhancing the ease of use of the cable management ring 100, and effectively solving the problems of complex direction adjustment, insufficient flexibility, and inconvenient installation and maintenance of existing cable management rings 100.

[0045] In one embodiment of this utility model, the cover plate 2 is provided with a rotating shaft 21, the base 1 is provided with a shaft hole 12, the rotating shaft 21 is rotatably connected in the shaft hole 12, the axial direction of the rotating shaft 21 is perpendicular to the extension direction of the base 1, and the axial direction of the rotating shaft 21 is perpendicular to the rotation direction of the cover plate 2.

[0046] In this embodiment, combined with Figure 1 , Figure 5 , Figure 7 It should be noted that the axial direction of the rotating shaft 21 is perpendicular to the extension direction of the base 1 and the rotation direction of the cover plate 2. This design makes the rotation plane of the cover plate 2 parallel to the surface of the base 1. When the cover plate 2 rotates around the rotating shaft 21, its trajectory is a circular motion perpendicular to the surface of the base 1. That is, the cover plate 2 rotates left and right relative to the base 1. The cover plate 2 is provided with a rotating shaft 21, and the base 1 is provided with a shaft hole 12. The rotating shaft 21 is rotatably disposed in the shaft hole 12, that is, the rotating shaft 21 is inserted into the shaft hole 12 to achieve a rotatable connection. It can be understood that the shape of the rotating shaft 21 is adapted to the shape of the shaft hole 12. The rotating shaft 21 is polygonal in this case, and the cross section of the corresponding shaft hole 12 is polygonal, thereby increasing the rotational damping. The cantilever length of the rotating shaft 21 is not limited and can be set according to specific circumstances. Preferably, combined with Figure 1 In order to save materials, the base 1 is also provided with a through groove, which runs through the base 1 along the width direction and connects to the shaft hole 12.

[0047] In one embodiment of the present invention, a positioning pin 22 is provided on one side of the cover plate 2, and an insertion hole 13 is provided on the side wall of the base 1; when the cover plate 2 is placed on the groove of the cable management groove 11, the positioning pin 22 is slidably limited within the insertion hole 13.

[0048] In this embodiment, to achieve precise positioning, the engagement of the positioning pin 22 and the insertion hole 13 ensures that the cover plate 2 is precisely positioned when it is placed over the opening of the cable management groove 11, preventing offset or misalignment of the cover plate 2 and improving the fitting accuracy between the cover plate 2 and the base 1. Combined with... Figure 2 , Figure 5 as well as Figure 7 The positioning pin 22 slides within the insertion hole 13, providing a stable fixing effect and preventing the cover plate 2 from loosening or falling off due to external forces during use, thus enhancing the reliability of the entire device. Simultaneously, the cooperation between the positioning pin 22 and the insertion hole 13 ensures that the cover plate 2 is accurately positioned when it is placed over the opening of the cable management groove 11, preventing offset or misalignment of the cover plate 2 and improving the fitting accuracy between the cover plate 2 and the base 1.

[0049] In one embodiment of the present invention, the side wall of the base 1 near the free end of the cover plate 2 has two guide sections 14 and a straight section 15. The straight section 15 is provided with a plug hole 13, and the two guide sections 14 are inclined in opposite directions.

[0050] In this embodiment, combined with Figure 8 The two guide segments 14 are inclined in opposite directions, forming a gradual guide path. When the locating pin 22 of the cover plate 2 approaches the insertion hole 13, the guide segment 14 can guide the locating pin 22 to gradually enter the insertion hole 13 along the inclined direction, reducing alignment difficulty. The insertion hole 13 of the straight segment 15 provides a stable fixed position, ensuring that the locating pin 22 remains stable after insertion, preventing the cover plate 2 from moving. The above arrangement reduces the alignment difficulty during installation and improves installation efficiency.

[0051] In one embodiment of the present invention, the rotating shaft 21 is polygonal in shape, the wall of the rotating shaft 21 is rounded, and the shape of the rotating shaft 21 is adapted to the shape of the shaft hole 12.

[0052] In this embodiment, combined with Figure 8 Understandably, to increase rotational damping, the shaft 21 is polygonal, and the shape of the corresponding shaft hole 12 matches the shape of the shaft 21. In one embodiment, the shaft 21 is hexagonal, with each side transitioning through an arc. The shaft hole 12 is also hexagonal. The hexagonal design provides six contact surfaces, increasing the contact area and improving rotational stability and accuracy. The arc transition reduces friction and wear. In another embodiment, the shaft 21 is octagonal, with each side transitioning through an arc. The shaft hole 12 can also be octagonal, matching the shape of the shaft 21. The octagonal design provides more contact surfaces, further improving rotational stability and accuracy. The arc transition reduces friction and wear. The polygonal design of the shaft 21 provides multiple contact surfaces with the inner wall of the shaft hole 12, increasing the contact area and thus improving rotational stability and accuracy. Each side of the polygon can serve as a support point, distributing force and reducing localized wear. The above configuration ensures good contact and precise fit between the rotating shaft 21 and the shaft hole 12, reducing shaking and instability during rotation.

[0053] In one embodiment of the present invention, the end of the rotating shaft 21 away from the cover plate 2 is provided with an elastic buckle. The elastic buckle includes two elastic buckle arms 21a spaced apart. Each elastic buckle arm 21a passes through the shaft hole 12 and abuts against the periphery of the shaft hole 12 facing away from the base 1.

[0054] In this embodiment, combined with Figure 3It should be noted that, for ease of installation, the end of the rotating shaft 21 furthest from the cover plate 2 is provided with an elastic buckle. The elastic buckle includes two spaced elastic arms 21a. The spaced elastic arms 21a have a gap between them, thus ensuring that the elastic arms 21a have a certain elasticity. When the rotating shaft 21 is inserted into the shaft hole 12, the elastic arms 21a will deform and pass through the shaft hole 12, abutting against the periphery of the shaft hole 12 facing away from the base 1, thereby achieving fixation.

[0055] In one embodiment of the present invention, the side of the base 1 facing away from the cable management groove 11 is recessed in the direction of the opening of the cable management groove 11 to form a groove.

[0056] In this embodiment, in order to further enhance the structural strength of the base 1 and improve the stability of the entire cable management ring 100, the side of the base 1 facing away from the cable management groove 11 is recessed in the direction of the opening of the cable management groove 11 to form a groove. The design of the groove can increase the cross-sectional area of ​​the base 1, thereby improving its bending and compressive strength.

[0057] In one embodiment of the present invention, a mating groove 16 is formed at one end of the base 1. The mating groove 16 is spaced apart from the cable management groove 11. The mating groove 16 is configured to be hinged to the protective cover 211 of the patch panel 200.

[0058] And / or, the base 1 is also provided with a snap-fit ​​groove 17, which is spaced apart from the cable management groove 11, and the snap-fit ​​groove 17 is configured to snap into the protective cover 211 of the patch panel 200.

[0059] In this embodiment, combined with Figure 1 , Figure 4 as well as Figure 6 It is understandable that the mating groove 16 is used to hinge with the protective cover 211 on the patch panel 200, allowing the protective cover 211 to rotate flexibly relative to the cable management ring 100 while maintaining connection stability. It should be noted that when the cable management ring 100 and the protective cover 211 are mated, the mating groove 16 is located at the end of the cable management ring 100 furthest from the fiber optic patch box, thus providing a hinge point for the protective cover 211.

[0060] Combination Figure 1 , Figure 4 as well as Figure 6It is understandable that the snap-fit ​​slot 17 is used to snap into the protective cover 211 of the patch panel 200, thereby ensuring a tight connection between the cable management ring 100 and the protective cover 211. It should be noted that when the cable management ring 100 and the protective cover 211 are engaged, the snap-fit ​​slot 17 is located at the end of the cable management ring 100 near the fiber optic patch box, thus providing a fixing point for the protective cover 211. The snap-fit ​​slot 17 and the mating slot 16 are spaced apart on both sides of the cable management slot 11, and the mating slot 16, the cable management slot 11, and the snap-fit ​​slot 17 extend along the length of the base 1.

[0061] This utility model also proposes a patch panel 200, which includes a tray 210 and a cable management ring 100 as described above. The specific structure of the cable management ring 100 is as described in the above embodiments. Since this patch panel 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The tray 210 is connected to the cable management ring 100.

[0062] In this embodiment, combined with Figures 9 to 12 It should be noted that tray 210 supports the entire patch panel 200, while cable management ring 100 is used for cable organization and guidance. Understandably, this is combined with... Figure 11 and combination Figure 12 The patch panel 200 also includes a frame 230 and a fiber optic patch panel 220 (or fiber optic connector, not shown in the figure). The cable management ring 100 and the fiber optic patch panel 220 are mounted on a tray 210, which is located inside the frame 230. The cable management ring 100 is positioned on one side of the fiber optic patch panel 220 (or fiber optic connector) to store the fiber optic cables of the patch panel 220 (or fiber optic connector). The tray 210 is made of sheet metal. The connection method between the tray 210 and the cable management ring 100 includes, but is not limited to, snap-fit, bolt connection, and plug-in connection, etc., which are not specified here. In one embodiment, the cable management ring 100 is fixed to the tray 210 by fasteners such as screws; in another embodiment, one end of the cable management ring 100 is provided with a buckle, and the tray 210 is provided with a buckle groove that matches the buckle, and the buckle is engaged and limited within the buckle groove; or one end of the cable management ring 100 is provided with a buckle groove, and the tray 210 is provided with a buckle that matches the buckle groove, and the buckle is engaged and limited within the buckle groove.

[0063] In one embodiment of the present invention, the tray 210 is provided with a protective cover 211, one end of the protective cover 211 is hinged to the cable management ring 100, and the other end of the protective cover 211 is snapped into the cable management ring 100.

[0064] In this embodiment, combined with Figure 10It is understood that the patch panel 200 has two cable management rings 100 located on opposite sides of the tray 210, and the two cable management rings 100 have the same structure. Furthermore, to prevent the optical fiber from rubbing or pulling against the top cover or other structures of the patch panel 200 frame 230, causing the optical fiber or optical fiber connector inside the fiber optic patch box 220 to become loose or damaged, a protective cover 211 is provided on the tray 210 to isolate the optical fiber cable from the top cover or other structures of the patch panel 200 frame 230. Taking one of the cable management rings 100 as an example, it should be noted that one end of the protective cover 211 forms a hook-shaped structure, which is hinged to the mating groove 16 of the cable management ring 100. The hook-shaped structure extends into the mating groove 16 and is hinged to one side wall of the mating groove 16, allowing the protective cover 211 to rotate around the connection point (i.e., the hinge point) between the hook-shaped structure and the mating groove 16, thus facilitating opening and closing. The other end of the protective cover 211 extends outward to form a snap-fit ​​section. When the protective cover 211 engages with the cable management ring 100, the snap-fit ​​section is positioned within the snap-fit ​​groove 17, which is sized and fitted to the snap-fit ​​section. The other end of the protective cover 211 is secured to the cable management ring 100 via a snap-fit ​​mechanism, ensuring that the protective cover 211 covers part of the fiber optic cable when closed, preventing the fiber optic cable from becoming loose. This design allows the protective cover 211 to be easily opened and closed, facilitating cable installation, inspection, and maintenance.
