Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of optical fiber communications, and in particular to a cable reel, a cable package, and a package structure. Background Art

[0002] With the rapid development of information technology, fiber-optic communication technology has gradually become a key means of achieving high-speed, high-capacity data transmission. As a key access method in fiber-optic communications, FTTx (Fiber To The x) covers a variety of application scenarios, including FTTH (Fiber To The Home), FTTM (Fiber To The Machine), FTTD (Fiber To The Desktop), FTTR (Fiber To The Room), and FTTR-B (Fiber To The Room-Building). FTTH primarily targets home users, providing high-speed internet access, IPTV (Internet Protocol Television), and other services. FTTM is used in the industrial sector, providing reliable connectivity for equipment. FTTD extends fiber to office desks, meeting the network performance requirements of modern offices. FTTR and FTTR-B further extend fiber to every room in homes and buildings, achieving high-speed network coverage throughout the home or building.

[0003] In fiber-to-the-room applications like FTTR, devices like information panels (fiber information sockets) and splitter panels play a key role. Information panels are typically installed in rooms, serving as the terminal device for fiber connections and providing network access points for users. Splitter panels distribute optical signals to multiple rooms, ensuring stable optical signals in every room and achieving efficient network coverage.

[0004] However, various cable-related panels in optical networks generally have a preset length of cable built into them. Furthermore, the length or type of cable built into the panel varies depending on the panel's usage scenario (e.g., installation environment) to facilitate later adjustments. However, due to the limited space within the panel, how to rationally utilize this limited space and optimize the layout and connection of cables to achieve the effects of "hiding wires," "storing fibers," "storing cables," and "coiling fibers" has become a pressing issue. This not only affects the compactness and aesthetics of the equipment, but also the transmission performance and ease of maintenance of the cables. Summary of the Invention

[0005] The embodiments of the present invention provide a cable reel, cable packaging, and packaging structure, which at least solves the problem in the related art that it is difficult to reasonably utilize the "wire hiding", "fiber storage", "cable storage", and "fiber coiling" space within the panel, resulting in difficulty in adapting to various panel usage scenarios.

[0006] According to one embodiment of the present invention, a cable drum is provided, comprising: a cable shaft for winding a cable; and a limiting portion provided at an end of the cable shaft, the size of which can be adjusted according to the amount of the wound cable.

[0007] According to another embodiment of the present invention, a cable package is provided, comprising: the cable drum as described in any one of the above items, and a cable wound on a cable spool of the cable drum.

[0008] According to another embodiment of the present invention, there is provided a packaging structure, comprising: the cable packaging as described above, and a terminal box in which the cable packaging is installed.

[0009] According to one embodiment of the present invention, the type or length of cables used with the panel may vary depending on the installation location of the panel. As the type or length of the cable wound on the cable spool (cables of different types or lengths have different total thicknesses after being wound on the cable spool) changes, the installer can adjust the length of the stopper based on the actual installation location so that the length of the stopper meets the total thickness of the cable wound on the cable spool, thereby achieving a cable restraint effect and thereby confining the cable within the limited space between the cable spool and the stopper. Furthermore, the "wire storage," "fiber storage," "cable storage," and "fiber coiling" spaces within different panels vary. The installer can also adjust the length of the stopper based on the size of the "wire storage," "fiber storage," "cable storage," and "fiber coiling" spaces to adjust the total volume of the cable reel formed by the cable spool and the stopper, so that the cable reel with the cable wound can be installed within the "wire storage," "fiber storage," "cable storage," and "fiber coiling" spaces of the panel, providing greater adaptability. Therefore, at least the problem in related technologies that it is difficult to reasonably utilize the "wire hiding", "fiber storage", "cable storage" and "fiber coiling" space within the panel, which makes it difficult to adapt to various panel usage scenarios, is solved, thereby achieving the effect of reserving cables of different lengths within the panel based on changes in the panel's usage scenarios.

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with embodiments.

[0018] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0019] In this embodiment, a cable drum is provided, which includes: a cable shaft for winding the cable; and a limiting portion provided at the end of the cable shaft, the size of which can be adjusted according to the amount of the wound cable.

[0020] In an exemplary embodiment, one or both end faces of the cable shaft are provided with a limiting groove, which can be plugged into and matched with positioning columns, bolts, etc. in the panel to install the cable shaft in the panel.

[0021] In one embodiment, the size of the limiting portion is adjustable along the axial and / or radial direction of the cable shaft.

[0022] In one embodiment, the cable spool is of an adjustable length or adjustable thickness structure, or a structure that is adjustable in both length and thickness. Therefore, in an exemplary embodiment, if it is necessary to change the amount of cable wound on the cable spool or to wind cables of different sizes or types, adaptive adjustment can be achieved by changing the length of the cable spool, changing the thickness of the cable spool, or changing both the length and thickness of the cable spool.

[0023] For example, consider a cable shaft with a cylindrical shaft structure. If the limiting portion can effectively block the cable, a cable with an outer diameter of 130 μm can be wound around the cable shaft 20 times. If a cable with an outer diameter of 140 μm needs to be wound around the cable shaft, the outer layer of the cable may not be blocked by the limiting portion after winding 20 turns of the increased outer diameter cable around the cable shaft, potentially causing the outer layer of cable to become loose. In this case, the limiting portion can be left unchanged, and the diameter of the cable shaft can be reduced, so that the outer layer of cable moves toward the reduced diameter cable shaft, allowing the extended portion of the limiting portion to also block and restrain the outer layer of cable. Alternatively, if the outer diameter of the cable increases, the length of the cable shaft can be increased to increase the number of turns of the cable wound around the cable shaft in the longitudinal direction, allowing the extended portion of the limiting portion to also block and restrain the outer layer of cable. Alternatively, when the outer diameter of the cable increases, the diameter of the cable shaft can be reduced so that the outer layer of cable moves toward the cable shaft with a reduced diameter, and the length of the cable shaft can be increased to increase the number of turns of the cable wound around the cable shaft in the length direction, so that the extended part of the limit portion can also shield and restrain the outer layer of cable.

[0024] Alternatively, if material conservation or compatibility is a concern, not only is it necessary to coil a cable with an outer diameter of 125 μm around the cable spool, but it is also necessary to meet the requirement of winding 20 turns of cable. When 20 turns of a cable with a reduced outer diameter are wound around the cable spool, the maximum distance of the stopper in the thickness direction of the winding (the diameter direction of the cable spool) may be greater than the thickness of the cable in the thickness direction of the winding (the diameter direction of the cable spool), resulting in unnecessary waste of material. Therefore, the stopper can be left unchanged and the length of the cable spool can be reduced to reduce the number of turns of cable wound along the length of the cable spool, so that the stopper can precisely block and restrain the 20 turns of the 125 μm outer diameter cable around the cable spool. Alternatively, if the outer diameter of the cable is reduced, the diameter of the cable spool can be increased to move the outer layer of cable away from the increased diameter cable spool, so that the stopper can precisely block and restrain the 20 turns of the 125 μm outer diameter cable around the cable spool. Alternatively, when the outer diameter of the cable is reduced, the length of the cable shaft can be reduced to reduce the number of turns of the cable wound on the cable shaft in the length direction, and the diameter of the cable shaft can be increased to move the outer layer of cable away from the cable shaft with increased diameter, so that the limiting part can just block and restrain the cable with an outer diameter of 125um that is wound 20 times on the cable shaft.

[0025] In an exemplary embodiment, the limiting portion is a structure that is adjustable along the radial direction of the cable shaft (in the thickness direction of the winding), so that the limiting portion can be adjusted in the thickness direction of the winding. For example, when the limiting portion is a disc-shaped structure and the cable shaft is a cylindrical shaft structure, the limiting portion is provided at the end of the cable shaft, and the center of the limiting portion coincides with the rotation center axis of the cable shaft. Therefore, the distance between the outer circular surface of the limiting portion and the outer peripheral surface of the cable shaft is the maximum distance between the limiting portion and the cable shaft. Within the range of this maximum distance, the limiting portion can shield and restrain the cable wound on the cable shaft. Therefore, the maximum distance can be adjusted based on the winding requirements on the cable shaft. For example, the maximum distance can be increased or reduced.

[0026] Specifically, taking the cable shaft as a cylindrical shaft structure as an example, the limiting portion is a structure that is adjustable along the diameter direction of the cable shaft. For example, when the limiting portion can effectively block the cable, the number of turns of a cable with an outer diameter of 130um that can be wound on the cable shaft is 20 turns. When it is necessary to wind a cable with an outer diameter of 140um on the cable shaft, the cable with an increased outer diameter that is wound 20 turns on the cable shaft may cause the outer layer of the cable to be unable to be blocked by the limiting portion, which may cause the outer layer of the cable to become loose. In this case, the length of the cable shaft can be kept unchanged, and the limiting portion can be extended in the thickness direction of the winding (the diameter direction of the cable shaft), so that the extended portion of the limiting portion can also block and restrain the outer layer of the cable. That is, the maximum distance is increased.

[0027] Alternatively, the limiting portion may remain unchanged, the length of the cable shaft may be increased, and the number of turns of the cable in the length direction of the cable shaft may be increased, so that the limiting portion can block and restrain the cable with an outer diameter of 140 μm and 20 turns wound on the cable shaft.

[0028] Similarly, for example, when material conservation or adaptability are considered, it is necessary not only to coil a cable with an outer diameter of 125um on the cable spool, but also to meet the requirement of coiling 20 turns of cable. When 20 turns of cable with a reduced outer diameter are coiled on the cable spool, the above-mentioned maximum distance of the limiter in the thickness direction of the winding (the diameter direction of the cable spool) may be greater than the thickness of the cable in the thickness direction of the winding (the diameter direction of the cable spool), resulting in unnecessary waste of material. Therefore, the length of the cable spool can be kept unchanged, and the limiter can be reduced in the thickness direction of the winding (the diameter direction of the cable spool) so that the limiter can just block and restrain the outer layer of cable. In other words, the maximum distance is reduced.

[0029] Alternatively, the limiting portion is a structure that is adjustable in the length direction of the cable shaft, for example, by changing the thickness of the limiting portion.

[0030] For example, if the stopper can effectively block the cable, a cable with an outer diameter of 130 μm can be wound around the cable spool 20 times. If a cable with an outer diameter of 125 μm needs to be wound around the cable spool, the cable with a reduced outer diameter wound 20 times around the cable spool may have a thickness in the thickness direction of the winding (the diameter of the cable spool) that is less than the aforementioned maximum distance of the stopper in the thickness direction of the winding (the diameter of the cable spool), increasing the difficulty of removing the cable from the cable spool. Therefore, the length of the cable spool can be kept unchanged, the thickness of the stopper can be increased, and the number of turns of the cable with an outer diameter of 125 μm can be reduced in the length direction of the cable spool, thereby increasing the number of turns of the cable with an outer diameter in the thickness direction of the cable spool (the diameter of the cable spool). This allows the stopper to precisely block and restrain the 20 turns of the cable with an outer diameter of 125 μm wound around the cable spool.

[0031] Similarly, when a cable with an outer diameter of 140 μm needs to be wound around a cable spool, the cable with an increased outer diameter that is wound 20 times around the cable spool may have a thickness in the thickness direction of the winding (the diameter direction of the cable spool) that is greater than the aforementioned maximum distance of the limiting portion in the thickness direction of the winding (the diameter direction of the cable spool). The outer layer of cable may not be blocked by the limiting portion, which may cause the outer layer of cable to become loose. To address this situation, the length of the cable spool can be kept unchanged, the thickness of the limiting portion can be reduced, and the number of turns of the cable with an outer diameter of 140 μm that are wound in the length direction of the cable spool can be increased to reduce the number of turns of the cable in the thickness direction of the cable spool (the diameter direction of the cable spool). This allows the limiting portion to just block and restrain the cable with an outer diameter of 140 μm that has been wound 20 times around the cable spool.

[0032] Of course, it should be noted that the cable shaft and the limiting portion can also be adjusted together. The adjustment principle is the same as above and will not be elaborated here.

[0033] In an exemplary embodiment, the stopper is disposed at an end of the cable shaft, and the direction in which the stopper extends is different from the direction in which the cable shaft extends. For example, the direction in which the cable shaft extends is the longitudinal direction of the cable shaft. The direction in which the stopper extends is perpendicular to the direction in which the cable shaft extends, or the direction in which the stopper extends is any angle between perpendicular and parallel to the cable shaft.

[0034] Figure 1 Schematic diagram of the structure of the cable drum according to an embodiment of the present invention. Figure 1As shown, in an exemplary embodiment, the stopper 2 can restrain the cable on the cable spool 1. Different types of cables have varying diameters, flexibility, and other characteristics, and the total radial thickness of the cable spool 1 occupied by the cable wound around it inevitably varies. Therefore, the length of the stopper 2 can be adjusted to accommodate variations in the total radial thickness of the cable spool 1 occupied by the cables wound around it, achieving a robust restraint effect for all types of cables.

[0035] By adopting the above technical solution, the type or length of the cable used with the panel will vary depending on the installation location of the panel. As the type or length of the cable coiled on the cable spool changes (cables of different types or lengths have different total thicknesses after being coiled on the cable spool), the installer can adjust the length of the stopper based on the actual installation location so that the length of the stopper meets the total thickness of the cable coiled on the cable spool, thereby achieving a cable restraint effect and thereby restraining the cable within the limited space between the cable spool and the stopper. Moreover, the "wire hiding," "fiber storage," "cable storage," and "fiber coiling" space within different panels varies. The installer can also adjust the length of the stopper based on the size of the "wire hiding," "fiber storage," "cable storage," and "fiber coiling" space to adjust the total volume of the cable reel formed by the cable spool and the stopper, so that the cable reel with the cable coiled can be installed within the "wire hiding," "fiber storage," "cable storage," and "fiber coiling" space of the panel, thereby achieving strong adaptability. Therefore, at least the problem in related technologies that it is difficult to reasonably utilize the "wire hiding", "fiber storage", "cable storage" and "fiber coiling" space within the panel, which makes it difficult to adapt to various panel usage scenarios, is solved, thereby achieving the effect of reserving cables of different lengths within the panel based on changes in the panel's usage scenarios.

[0036] It should be noted that the cables in the embodiments of the present invention may be optical fibers, optical cables, electrical cables, copper cables, etc. The embodiments of the present invention are explained below using optical fibers as an example, but the same applies to optical cables, electrical cables, copper cables, etc. Of course, the cable reels in the embodiments of the present invention may also be referred to as cable storage reels, cable delivery reels, cable reels, cable winding devices, or cable reels.

[0037] In one embodiment, the limiting portions are provided in pairs to clamp the cable spool between the two limiting portions.

[0038] In an exemplary embodiment, the structures of the limiting portions arranged in pairs may be the same or different.

[0039] In one embodiment, there is only one limiting portion, which is disposed at one end of the cable shaft.

[0040] In an exemplary embodiment, a stopper located at one end of the cable shaft can constrain the optical fiber at one end of the cable shaft. The other end of the cable shaft can be connected to the inner wall of the panel, thereby utilizing the inner wall of the panel to constrain the optical fiber at the other end of the cable shaft. The optical fiber can then be constrained between the stopper and the inner wall of the panel.

[0041] In one embodiment, the limiting portion is a multi-layer structure in the thickness direction of the winding, wherein adjacent layers are detachable or bendable. For example, taking the cable shaft as a cylindrical shaft structure, the thickness direction of the winding is the diameter direction of the cable shaft.

[0042] In one embodiment, adjacent layers of the limiting portion are connected in a point-like manner and / or in a virtual manner.

[0043] Figure 2 This is a schematic diagram of the overall structure of a cable drum having a three-layer structure as a limiting portion according to an embodiment of the present invention. Figure 3 Schematic diagram of the first structural member, the second structural member, and the third structural member of the position limiting portion according to an embodiment of the present invention. Figure 2 and Figure 3 As shown, in an exemplary embodiment, the limiting portion 2 is explained as a three-layer structure, and the limiting portion 2 includes: a first structural member 21, a second structural member 22, and a third structural member 23. Among them, the first structural member 21 is located in the innermost layer, and one end of the cable shaft 1 is connected to the inner wall of the first structural member 21 (the inner wall is the side wall of the first structural member 21 facing the cable shaft 1). Among them, welding, threaded connection, clamping and other connection methods can be used between one end of the cable shaft 1 and the first structural member 21. The second structural member 22 is located in the middle, and the third structural member 23 is located in the outermost layer. The first structural member 21, the second structural member 22, and the third structural member 23 extend along the radial direction of the cable shaft 1. The first structural member 21, the second structural member 22, and the third structural member 23 are detachably connected to each other.

[0044] In the radial direction of the cable spool 1, the end face of the first structural member 21 facing away from the cable spool 1 is the outer end face of the first structural member 21, the end face of the second structural member 22 close to the cable spool 1 is the inner end face of the second structural member 22, the end face of the second structural member 22 facing away from the cable spool 1 is the outer end face of the second structural member 22, and the end face of the third structural member 23 close to the cable spool 1 is the inner end face of the third structural member 23. The outer end face of the first structural member 21 and the inner end face of the second structural member 22 are connected in a point-like manner or in a virtual connection, and the outer end face of the second structural member 22 and the inner end face of the third structural member 23 are connected in a point-like manner or in a virtual connection.

[0045] For example, the second structural member 22 and the third structural member 23 are both annular structures, the second structural member 22 is nested on the outside of the first structural member 21, and the third structural member 23 is nested on the outside of the second structural member 22. Therein, a plurality of spaced connection blocks are provided between the outer end face of the first structural member 21 and the inner end face of the second structural member 22, and a plurality of spaced connection blocks are provided between the outer end face of the second structural member 22 and the inner end face of the third structural member 23. Alternatively, the first structural member 21, the second structural member 22, and the third structural member 23 are an integral structure, a plurality of spaced grooves are provided between the outer end face of the first structural member 21 and the inner end face of the second structural member 22, and the aforementioned connection blocks are provided between adjacent grooves. A plurality of spaced grooves are provided between the outer end face of the second structural member 22 and the inner end face of the third structural member 23, and the aforementioned connection blocks are provided between adjacent grooves. Therefore, the third structural member 23 can be separated from the second structural member 22, or the second structural member 22 can be separated from the first structural member 21, by shearing, cutting, or breaking the connecting block (e.g., reducing the maximum distance as described above). Alternatively, the third structural member 23 can be connected to the second structural member 22, or the second structural member 22 can be connected to the first structural member 21, by gluing the connecting block (e.g., increasing the maximum distance as described above). Therefore, by adopting the above technical solution, the length of the limiter 2 can be adjusted based on the actual installation environment to accommodate changes in the optical fiber on the cable spool 1.

[0046] For example, in order to facilitate the separation of the first structural member 21, the second structural member 22, and the third structural member 23, a connecting block with a thinner thickness and a softer material can be selected, or grooves or holes can be made on the connecting block to reduce the structural strength of the connecting block, so that the installer can disconnect the connecting block with less effort.

[0047] Alternatively, a non-through groove (e.g., a non-through notch) is provided between the first structural member 21 and the second structural member 22, and a non-through groove is provided between the second structural member 22 and the third structural member 23. Alternatively, a combination of a non-through groove and a through groove (e.g., a through notch) is provided between the first structural member 21 and the second structural member 22 (e.g., non-through notches and through notches are alternately arranged in an annular position between the first structural member 21 and the second structural member 22), and a combination of a non-through groove and a through groove is provided between the second structural member 22 and the third structural member 23, so that the installer can effortlessly disconnect the first structural member 21 and the second structural member 22 and the third structural member 23. All of these structures are conceivable.

[0048] Alternatively, the first structural member 21 and the second structural member 22 can be bent relative to each other, and the second structural member 22 and the third structural member 23 can be bent relative to each other. The second structural member 22 and the third structural member 23 can be open-loop structures, strip structures, block structures, or the like, so that the length of the limiting portion in the winding thickness direction can be changed by bending the second structural member 22, the third structural member 23, or both.

[0049] Among them, Figure 2 The maximum distance mentioned above is shown in FIG, i.e., the distance between the outer circumference of the limit portion and the outer circumference of the cable shaft. It should be noted that the maximum distance can be adjusted based on the winding requirements on the cable shaft. Figure 2 The example is just an example, and the distance shown in the figure does not limit this solution.

[0050] In one embodiment, the limiting portion includes: a movable arm that is adjustable in the thickness direction of the winding.

[0051] In an exemplary embodiment, for example, the movable arm can slide relative to the cable shaft in the thickness direction of the winding, or the movable arm can expand and contract relative to the cable shaft in the thickness direction of the winding to change the distance between the end of the movable arm away from the cable shaft and the cable shaft.

[0052] In one embodiment, the movable arm slides relative to the end of the cable shaft along the thickness direction of the winding wire.

[0053] In one embodiment, the limiting portion further includes: an end plate, which is arranged at the end of the cable shaft, and the movable arm slides relative to the end plate along the thickness direction of the winding.

[0054] In one embodiment, the end plate and the cable spool are an integral structure.

[0055] In an exemplary embodiment, for example, the end plate and the cable shaft can be obtained by mold casting or the like, so that the end plate and the cable shaft are an integrated structure, thereby meeting the requirements for structural strength and stability.

[0056] In one embodiment, the end plate and the cable reel are detachable structures.

[0057] In an exemplary embodiment, for example, the end plate and the cable reel may be connected in a detachable manner such as bolts, screws, mortise and tenon joints, thereby facilitating adjustment and replacement of the end plate and the cable reel.

[0058] In one embodiment, a first sliding groove is provided on the surface of the end plate, and one end of the movable arm slides in the first sliding groove along the extension direction of the end plate.

[0059] In one embodiment, a damping groove is provided in the first sliding groove, and a damping block is provided at one end of the movable arm.

[0060] In one embodiment, a damping block is provided in the first sliding groove, and a damping groove is provided at one end of the movable arm.

[0061] Figure 4 is a schematic diagram of the overall structure of a cable drum according to an embodiment of the present invention, wherein the limiting portion includes an end plate and a movable arm. Figure 4 As shown, in an exemplary embodiment, for example, the end plate 24 is disc-shaped, and one end of the cable shaft 1 is connected to the center position of the end plate 24. The first slide groove can be one or more. In order to facilitate symmetry and achieve a better binding effect, the embodiment of the present invention preferably has six first slide grooves, and the six first slide grooves extend along the radial direction of the cable shaft 1 and are arranged at intervals along the axial direction of the cable shaft 1. The movable arm 25 is arranged in cooperation with the first slide groove so that one end of the movable arm 25 slides radially in the first slide groove to change the distance between the other end of the movable arm 25 and the cable shaft 1, thereby changing the length of the limit portion, thereby adapting to the change in the total thickness of the cable shaft 1 in the radial direction occupied by different optical fibers wound on the cable shaft 1, so as to achieve a good binding effect on different types of optical fibers.

[0062] The damping groove and the damping block are arranged in cooperation so that there is a certain damping between the movable arm 25 and the end plate 24, that is, the movable arm 25 can remain relatively fixed with the end plate 24 after moving a certain distance, so as to achieve the effect of binding the optical fiber.

[0063] In one embodiment, a second sliding groove is provided on the surface of the movable arm, and a slider is provided on the surface of the end plate. The slider is slidably connected to the second sliding groove, and the second sliding groove extends along the length direction of the movable arm.

[0064] In one embodiment, a damping groove is provided in the second sliding groove, and the sliding block is a damping block.

[0065] In one embodiment, the sliding block is provided with a damping groove, and a damping block is provided in the second sliding groove.

[0066] In an exemplary embodiment, of course, a second slide groove can be provided on the surface of the movable arm, and a slider can be provided on the surface of the end plate. Based on the sliding action of the second slide groove and the slider, the distance between the other end of the movable arm and the cable shaft can be changed to change the length of the limiting portion, thereby adapting to the change in the total radial thickness of the cable shaft occupied by different optical fibers wound on the cable shaft, so as to achieve a good binding effect on different types of optical fibers.

[0067] The damping groove and the damping block are arranged in cooperation so that there is a certain damping between the movable arm and the end plate, that is, the movable arm can remain relatively fixed with the end plate after moving a certain distance, so as to achieve the effect of binding the optical fiber.

[0068] In one embodiment, the first sliding groove may also be provided at the end of the cable shaft, and one end of the movable arm slides in the first sliding groove along the thickness direction of the winding.

[0069] In one embodiment, the slider may also be provided at the end of the cable shaft, and the slider is slidably engaged with a second sliding groove provided on the movable arm.

[0070] In one embodiment, the limiting portion includes: a folding arm, which is a segmented folding structure, one end of which is connected to the cable shaft, and the distance between the other end and the cable shaft can be adjusted.

[0071] Figure 5 FIG. 1 is a schematic structural diagram of a folding arm in an expanded state and a folded state according to an embodiment of the present invention. Figure 5 As shown, in an exemplary embodiment, there may be multiple folding arms 26, and when the multiple folding arms 26 are in the unfolded state (such as Figure 5 (See the left side of the figure), one end of each of the folding arms 26 is connected to the cable shaft 1, and the other ends of each of the folding arms 26 extend radially along the cable shaft 1. Each folding arm 26 is a segmented folding structure, that is, it includes multiple folding joints, and the multiple folding joints are connected in sequence. Therefore, the folding arm 26 can be transformed into a folded state (such as by rotating each folding joint in the direction close to the cable shaft 1) by rotating each folding joint in the direction close to the cable shaft 1. Figure 5 (See the accompanying figure on the right side of the figure.) Therefore, by adopting the above solution, the distance between the end of the folded arm 26 away from the cable shaft 1 and the cable shaft 1 can be changed to accommodate the variation in the total radial thickness of the cable shaft 1 occupied by different optical fibers wound around the cable shaft 1, thereby achieving a good binding effect on different types of optical fibers.

[0072] Figure 6 FIG. 1 is a schematic structural diagram of another folding arm in the expanded state and the folded state according to an embodiment of the present invention. Figure 6 As shown, in an exemplary embodiment, there may be multiple folding arms 26, and when the multiple folding arms 26 are in the unfolded state (such as Figure 6 (see the left side of the figure), one end of each of the folding arms 26 is connected to the cable shaft 1, and the other ends of each of the folding arms 26 extend radially along the cable shaft 1. Each folding arm 26 can be a polygonal telescopic structure, such as a parallelogram telescopic structure. By pushing one end of the folding arm 26 away from the cable shaft 1 in the direction close to the cable shaft 1, the distance between the end of the folding arm 26 away from the cable shaft 1 and the cable shaft 1 can be shortened, so that the folding arm 26 is transformed into a folded state (such as Figure 6(See the accompanying figure on the right side of the figure.) Pulling the end of the foldable arm 26 away from the cable spool 1 further away from the cable spool 1 increases the distance between the end of the foldable arm 26 away from the cable spool 1 and the cable spool 1, thereby transforming the foldable arm 26 into the unfolded state. Therefore, by adopting the above solution, the distance between the end of the foldable arm 26 away from the cable spool 1 and the cable spool 1 can be varied to accommodate variations in the total radial thickness of the cable spool 1 occupied by different optical fibers wound around the cable spool 1, thereby achieving a good binding effect on different types of optical fibers.

[0073] In this embodiment, a cable package is further provided, comprising: a cable drum as described in any one of the above items, and a cable wound on a cable reel of the cable drum.

[0074] This embodiment also provides a packaging structure comprising: the cable package described above, and a terminal box in which the cable package is installed. In one exemplary embodiment, the cable package is installed in the terminal box. For example, in the case of optical fiber, the cable package includes a cable drum wound with the optical fiber, one end of which is provided with an optical fiber connector. Different optical fiber connectors are connected via an adapter. The cable drum is removably installed in the terminal box.

[0075] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the principles of the present invention are intended to be within the scope of protection of the present invention.
