Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber communication, and more specifically, to a cable reel, cable encapsulation, and encapsulation structure. Background Technology

[0002] With the rapid development of information technology, fiber optic communication technology has gradually become a key means to achieve high-speed, high-capacity data transmission. FTTx (Fiber To The x), as an important access method in fiber optic communication, 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 is mainly for home users, providing high-speed internet access, IPTV (Internet Protocol Television), and other services; FTTM is used in the industrial field, providing reliable connections for machinery and equipment; FTTD extends fiber optic cables to office desktops, meeting the network performance requirements of modern offices; FTTR and FTTR-B further lay fiber optic cables to every room in homes and buildings, achieving high-speed network coverage throughout the entire house or building.

[0003] In fiber-to-the-room (FTTR) applications, equipment such as information panels (fiber optic information outlets) and splitter panels play a crucial role. Information panels are typically installed inside the room, serving as the terminal equipment for fiber optic connections and providing network access points for users. Splitter panels are used to distribute optical signals to multiple rooms, ensuring that each room receives a stable optical signal, thereby achieving efficient network coverage.

[0004] However, in optical networks, various cable-related panels typically contain a pre-set length of cable. 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 future adjustments. However, due to the limited space within the panel, how to rationally utilize this limited space and optimize cable layout and connection methods to achieve the effects of "hidden cable," "fiber storage," "cable storage," and "fiber coiling" has become a pressing issue. This not only relates to the compactness and aesthetics of the equipment but also affects the cable's transmission performance and ease of maintenance. Utility Model Content

[0005] This utility model provides a cable reel, cable encapsulation, and encapsulation structure, which at least solves the problem in related technologies that it is difficult to adapt to various panel usage scenarios due to the difficulty in making reasonable use of the space for "hiding wires", "storing fibers", "storing cables", and "coiling fibers" within the panel.

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

[0007] According to another embodiment of the present invention, a cable package is also provided, comprising: a cable reel as described in any of the preceding claims, and a cable on a cable spool wound around the cable reel.

[0008] According to another embodiment of the present invention, a packaging structure is also provided, including: the cable package as described above, and a terminal box on which the cable package is mounted.

[0009] In one embodiment of this invention, the type or length of the cable used with the panel varies depending on its installation position. As the type or length of the cable wound on the cable reel changes (the total thickness varies depending on the type or length of the cable wound on the reel), the installer can adjust the length of the limiting part based on the actual installation position. This ensures the length of the limiting part meets the total thickness of the cable wound on the reel, achieving a binding effect on the cable and confining it within the limited space between the reel and the limiting part. Furthermore, since different panels have different "hidden cable," "fiber storage," "cable storage," and "fiber coiling" spaces, the installer can also adjust the length of the limiting part based on the size of these spaces. This adjusts the total volume of the cable reel obtained from the cable reel and the limiting part, allowing the cable reel with the wound cable to be installed within the "hidden cable," "fiber storage," "cable storage," and "fiber coiling" spaces of the panel, demonstrating strong adaptability. Therefore, it at least solves the problem in related technologies that it is difficult to adapt to various panel usage scenarios due to the difficulty in making reasonable use of the space for "hiding wires", "storing fibers", "storing cables" and "coiling fibers" within the panel. This enables the panel to reserve cables of different lengths within the panel based on changes in the panel's usage scenario. Attached Figure Description

[0017] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0019] This embodiment provides a cable reel, which includes: a cable spool for winding a cable; and a limiting part disposed at the end of the cable spool, the size of which can be adjusted according to the amount of cable wound.

[0020] In one exemplary embodiment, a limiting groove is provided on one or both end faces of the cable spool, which can be used to insert and cooperate with positioning posts, bolts, etc. in the panel to install the cable spool 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 a length-adjustable structure, a thickness-adjustable structure, or a structure where both length and thickness are adjustable. Therefore, in an exemplary embodiment, when it is necessary to change the number of cables wound on the cable spool or to wind cables of a different size or type, adaptive adjustments can be made by changing the length of the cable spool, changing the thickness of the cable spool, or both the length and thickness of the cable spool.

[0023] For example, consider a cylindrical cable reel. When the limiting part effectively blocks the cable, 20 turns of cable with an outer diameter of 130µm can be wound on the cable reel. However, if a cable with an outer diameter of 140µm needs to be wound on the reel, the increased outer diameter might prevent the outer layer of cable from being blocked by the limiting part, potentially leading to loosening. To address this, the limiting part can remain unchanged while the diameter of the cable reel is reduced, causing the outer layer of cable to move closer to the reduced diameter reel, thus allowing the extended portion of the limiting part to also block and restrain the outer layer. Alternatively, when the outer diameter of the cable is increased, the length of the cable reel can be increased to increase the number of turns of cable wound along its length, ensuring that the extended portion of the limiting part also blocks and restrains the outer layer. Alternatively, when the outer diameter of the cable increases, the diameter of the cable spool can be reduced so that the outer cable moves toward the cable spool with the reduced diameter, and the length of the cable spool can be increased to increase the number of turns of the cable spool around the cable in the length direction, so that the extended part of the limiting part can also shield and restrain the outer cable.

[0024] Alternatively, when material conservation or compatibility is required, it may be necessary not only to wind a 125µm outer diameter cable onto the cable spool but also to meet the requirement of 20 turns of cable. When 20 turns of cable with a reduced outer diameter are wound onto the cable spool, the maximum distance of the limiting part 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 material waste. Therefore, the limiting part can remain unchanged, while the length of the cable spool can be reduced to decrease the number of turns of cable wound on the cable spool in the length direction, so that the limiting part can just barely block and restrain the 20 turns of 125µm outer diameter cable on the cable spool. Alternatively, when 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 cable spool with the increased diameter, so that the limiting part can just barely block and restrain the 20 turns of 125µm outer diameter cable on the cable spool. Alternatively, when the outer diameter of the cable is reduced, the length of the cable spool can be reduced to decrease the number of turns of the cable wound on the cable spool in the length direction, and the diameter of the cable spool can be increased to move the outer cable away from the cable spool with the increased diameter, so that the limiting part can just block and bind the cable with 20 turns and an outer diameter of 125um wound on the cable spool.

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

[0026] Specifically, taking a cylindrical cable spool as an example, the limiting part is an adjustable structure along the diameter direction of the cable spool. For example, when the limiting part can effectively block the cable, 20 turns of cable with an outer diameter of 130µm can be wound on the cable spool. When a cable with an outer diameter of 140µm needs to be wound on the cable spool, the increased outer diameter of the cable may prevent the outer layer of cable from being blocked by the limiting part, potentially leading to loosening of the outer layer. To address this, the length of the cable spool can remain unchanged, while the limiting part extends in the thickness direction of the winding (the diameter direction of the cable spool), so that the extended portion of the limiting part can also block and restrain the outer layer of cable. In other words, the maximum distance is increased.

[0027] Alternatively, the limiting part can remain unchanged, while the length of the cable spool can be increased, thereby increasing the number of turns of the cable wound along the length of the cable spool, so that the limiting part can shield and restrain the cable with an outer diameter of 140um that is wound 20 times on the cable spool.

[0028] Similarly, for example, when considering material saving or compatibility, it's necessary not only to wind a cable with an outer diameter of 125µm onto the cable spool, but also to meet the requirement of 20 turns of cable. When 20 turns of cable with a reduced outer diameter are wound onto the cable spool, the maximum distance of the limiting part in the thickness direction of the winding (the diameter direction of the cable spool) may be larger than the thickness of the cable in the thickness direction of the winding (the diameter direction of the cable spool), resulting in unnecessary material waste. Therefore, the length of the cable spool can remain unchanged, while the limiting part can be reduced in the thickness direction of the winding (the diameter direction of the cable spool) so that the limiting part can effectively shield and restrain the outer layer of cable. That is, reduce the maximum distance.

[0029] Alternatively, the limiting part can be an adjustable structure along the length of the cable spool, for example, by changing the thickness of the limiting part.

[0030] For example, when the limiting part can effectively block the cable, the number of turns of a cable with an outer diameter of 130µm can be wound on the cable spool 20 times. When a cable with an outer diameter of 125µm needs to be wound on the cable spool, the cable with a reduced outer diameter after 20 turns may have a thickness in the winding thickness direction (the diameter direction of the cable spool) that is less than the maximum distance of the limiting part in the winding thickness direction (the diameter direction of the cable spool) mentioned above, thus increasing the difficulty of removing the cable from the cable spool. Therefore, the length of the cable spool can be kept constant, the thickness of the limiting part can be increased, and the number of turns of the 125µm cable wound in the length direction of the cable spool can be reduced, thereby increasing the number of turns of the cable wound in the thickness direction (the diameter direction of the cable spool), so that the limiting part can just rightly block and restrain the 20 turns of the 125µm cable wound on the cable spool.

[0031] Similarly, when a cable with an outer diameter of 140µm needs to be wound on a cable spool, the increased outer diameter cable, wound 20 times on the spool, may result in the cable thickness in the winding thickness direction (the diameter direction of the cable spool) exceeding the maximum distance of the limiting part in the winding thickness direction (the diameter direction of the cable spool). This could lead to the outer layer of cable not being properly blocked by the limiting part, potentially causing it to become loose. To address this, the length of the cable spool can remain constant, while the thickness of the limiting part can be reduced. This increases the number of turns of the 140µm cable wound along the length of the cable spool, thereby reducing the number of turns in the thickness direction (the diameter direction of the cable spool). This ensures that the limiting part can effectively block and restrain the 20 turns of the 140µm cable wound on the spool.

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

[0033] In one exemplary embodiment, a limiting portion is provided at the end of the cable spool, and the extending direction of the limiting portion is different from the extending direction of the cable spool. For example, the extending direction of the cable spool is the length direction of the cable spool. The extending direction of the limiting portion is perpendicular to the extending direction of the cable spool, or the extending direction of the limiting portion is the direction corresponding to any angle between the limiting portion and the cable spool being perpendicular and parallel to each other.

[0034] Figure 1 This is a schematic diagram of the cable reel structure according to an embodiment of the present utility model, as shown below. Figure 1As shown, in one exemplary embodiment, the limiting part 2 can bind the cable to the cable spool 1. Different types of cables differ in diameter, flexibility, etc., and the total radial thickness of the cable spool 1 occupied by the cable coiled on it will inevitably vary. Therefore, by adjusting the length of the limiting part 2, the total radial thickness of the cable spool 1 occupied by different cables coiled on it can be accommodated, thereby achieving a good binding effect on different 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 position of the panel. As the type or length of the cable wound on the cable reel changes (the total thickness of different types or lengths of cable wound on the cable reel varies), installers can adjust the length of the limiting part based on the actual installation position. This ensures that the length of the limiting part meets the total thickness of the cable wound on the cable reel, achieving a binding effect on the cable and confining it within the limited space between the cable reel and the limiting part. Furthermore, different panels have different "hidden cable," "fiber storage," "cable storage," and "fiber coiling" spaces. Installers can also adjust the length of the limiting part based on the size of these spaces to adjust the total volume of the cable reel obtained from the cable reel and the limiting part. This allows the cable reel with the wound cable to be installed within the "hidden cable," "fiber storage," "cable storage," and "fiber coiling" spaces of the panel, demonstrating strong adaptability. Therefore, it at least solves the problem in related technologies that it is difficult to adapt to various panel usage scenarios due to the difficulty in making reasonable use of the space for "hiding wires", "storing fibers", "storing cables" and "coiling fibers" within the panel. This enables the panel to reserve cables of different lengths within the panel based on changes in the panel's usage scenario.

[0036] It should be noted that the cable in this embodiment of the present invention can be optical fiber, optical cable, electrical cable, copper cable, etc. The following explanation uses optical fiber as an example; the same applies to optical cables, electrical cables, copper cables, etc. Of course, the cable reel in this embodiment of the present invention can also be called a cable storage reel, cable delivery reel, cable reel, cable winding device, wire reel, etc.

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

[0038] In one exemplary embodiment, the structures of the paired limiting portions may be the same or different.

[0039] In one embodiment, there is only one limiting part, which is located at one end of the cable reel.

[0040] In one exemplary embodiment, the limiting portion located at one end of the cable reel can bind the optical fiber at that end of the cable reel. The other end of the cable reel can be connected to the inner wall of the panel, so that the inner wall of the panel can be used to bind the optical fiber at the other end of the cable reel. Thus, the optical fiber can be bound between the limiting portion and the inner wall of the panel.

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

[0042] In one embodiment, the adjacent layers of the limiting portion are connected by a dotted connection and / or a virtual connection.

[0043] Figure 2 This is a schematic diagram of the overall structure of a cable reel with a three-layer limiting part according to an embodiment of the present utility model. Figure 3 This is a schematic diagram of the first, second, and third structural members of the limiting portion according to an embodiment of the present utility model, as shown below. Figure 2 and Figure 3 As shown, in an exemplary embodiment, the limiting part 2 is explained using a three-layer structure as an example. The limiting part 2 includes: a first structural member 21, a second structural member 22, and a third structural member 23. The first structural member 21 is located in the innermost layer, and one end of the cable spool 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 spool 1). The connection between the end of the cable spool 1 and the first structural member 21 can be achieved by welding, threaded connection, snap-fit, or other methods. 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 radially along the cable spool 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 this configuration, radially along the cable shaft 1, the end face of the first structural member 21 facing away from the cable shaft 1 is its outer end face; the end face of the second structural member 22 near the cable shaft 1 is its inner end face; the end face of the second structural member 22 facing away from the cable shaft 1 is its outer end face; and the end face of the third structural member 23 near the cable shaft 1 is its inner end face. The outer end face of the first structural member 21 and the inner end face of the second structural member 22 are connected by a point or a loose 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 by a point or a loose connection.

[0045] For example, both the second structural member 22 and the third structural member 23 are ring-shaped structures. The second structural member 22 is nested outside the first structural member 21, and the third structural member 23 is nested outside the second structural member 22. Multiple spaced connecting 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 multiple spaced connecting blocks are also 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 a single integrated structure. Multiple spaced grooves are formed between the outer end face of the first structural member 21 and the inner end face of the second structural member 22, with the aforementioned connecting blocks between adjacent grooves. Multiple spaced grooves are also formed between the outer end face of the second structural member 22 and the inner end face of the third structural member 23, with the aforementioned connecting blocks 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 cutting, severing, 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 bonding the connecting block (e.g., increasing the maximum distance as described above). Therefore, by adopting the above technical solution, the length of the limiting part 2 can be adjusted according to the actual installation environment to accommodate changes in the optical fiber on the cable reel 1.

[0046] For example, in order to facilitate the separation of the first structural component 21, the second structural component 22, and the third structural component 23, a thinner and softer connecting block can be selected, or the structural strength of the connecting block can be reduced by slotting or drilling, so that the installer can disconnect the connecting block with less effort.

[0047] Alternatively, a non-penetrating groove (e.g., a non-penetrating notch) may be formed between the first structural member 21 and the second structural member 22, and a non-penetrating groove may be formed between the second structural member 22 and the third structural member 23. Alternatively, a combination of non-penetrating grooves and through grooves (e.g., through grooves) may be formed between the first structural member 21 and the second structural member 22 (e.g., non-penetrating grooves and through grooves are alternately arranged in an annular position between the first structural member 21 and the second structural member 22), and a combination of non-penetrating grooves and through grooves may be formed between the second structural member 22 and the third structural member 23, so that the installer can easily disconnect the first structural member 21 and the second structural member 22, and the second structural member 22 and the third structural member 23.

[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, or block structures, etc., so that the length of the limiting part in the winding thickness direction can be changed by bending the second structural member 22, bending the third structural member 23, or bending both the second and third structural members 22.

[0049] Among them, Figure 2 The diagram shows the aforementioned maximum distance, namely, the distance between the outer circular surface of the limiting part and the outer circumferential surface of the cable spool. It should be noted that this maximum distance can be adjusted based on the winding requirements on the cable spool. Figure 2 The example shown is merely one instance, and the distance illustrated does not constitute a limitation on this solution.

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

[0051] In one exemplary embodiment, for example, the movable arm may slide relative to the cable spool in the thickness direction of the winding, or the movable arm may deform such as stretching or contracting relative to the cable spool in the thickness direction of the winding to change the distance between the end of the movable arm away from the cable spool and the cable spool.

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

[0053] In one embodiment, the limiting part further includes an end plate disposed at the end of the cable reel, 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 reel are an integral structure.

[0055] In one exemplary embodiment, for example, the end plate and the cable reel can be obtained by means of mold casting, so that the end plate and the cable reel are an integral structure, thereby meeting the requirements for structural strength and stability.

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

[0057] In one exemplary embodiment, for example, the end plate and the cable reel can be connected by detachable means such as bolts, screws, or tenons, thereby facilitating the adjustment and replacement of the end plate and the cable reel.

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

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

[0061] Figure 4 This is a schematic diagram of the overall structure of a cable reel according to an embodiment of the present invention, including 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 of the end plate 24. There can be one or more first grooves; for symmetry and to achieve a better binding effect, this embodiment preferably uses six. The six first grooves extend radially along the cable shaft 1 and are spaced apart axially along the cable shaft 1. The movable arm 25 is configured to cooperate with the first groove, so that one end of the movable arm 25 slides radially within the first groove, changing the distance between the other end of the movable arm 25 and the cable shaft 1, thereby changing the length of the limiting portion. This adapts to variations in the total radial thickness of the cable shaft 1 occupied by different optical fibers coiled on it, achieving a good binding effect for different types of optical fibers.

[0062] The damping groove and damping block are designed to provide a certain amount of damping between the movable arm 25 and the end plate 24. This means that the movable arm 25 can remain relatively fixed with the end plate 24 after moving a certain distance, thereby achieving the effect of binding the optical fiber.

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

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

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

[0066] In one exemplary embodiment, a second 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 groove and the slider, the distance between the other end of the movable arm and the cable spool can be changed to change the length of the limiting part, thereby adapting to the changes in the total radial thickness of the cable spool occupied by different optical fibers coiled on it, so as to achieve a good binding effect for different types of optical fibers.

[0067] The damping groove and damping block are designed to provide a certain amount of damping between the movable arm and the end plate. This means that the movable arm can remain relatively fixed with the end plate after moving a certain distance, thereby achieving the effect of binding the optical fiber.

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

[0069] In one embodiment, the slider may also be disposed at the end of the cable spool, and the slider slides in cooperation with a second groove disposed on the movable arm.

[0070] In one embodiment, the limiting part includes a folding arm, which is a segmented folding structure, with one end connected to the cable spool and the distance between the other end and the cable spool adjustable.

[0071] Figure 5 This is a schematic diagram of the unfolded and folded states of a folding arm according to an embodiment of the present invention, as shown below. Figure 5 As shown, in one exemplary embodiment, there can be multiple folding arms 26, and when multiple folding arms 26 are in an unfolded state (e.g. Figure 5 (See the attached diagram on the left). One end of each of the multiple folding arms 26 is connected to the cable shaft 1, and the other end of each folding arm 26 extends radially along the cable shaft 1. Each folding arm 26 is a segmented folding structure, that is, it includes multiple folding joints connected sequentially. Therefore, the folding arm 26 can be folded by rotating each folding joint towards the cable shaft 1. Figure 5 (See attached diagram on the right). Therefore, by adopting the above scheme, the distance between the end of the folding arm 26 away from the cable shaft 1 and the cable shaft 1 can be changed to accommodate the changes in the total radial thickness of the cable shaft 1 occupied by different optical fibers coiled on it, so as to achieve a good binding effect for different types of optical fibers.

[0072] Figure 6 This is a schematic diagram of the unfolded and folded states of another folding arm according to an embodiment of the present invention, as shown below. Figure 6 As shown, in one exemplary embodiment, there can be multiple folding arms 26, and when multiple folding arms 26 are in an unfolded state (e.g. Figure 6 (See the attached diagram on the left). One end of each of the multiple folding arms 26 is connected to the cable shaft 1, and the other end of each folding arm 26 extends radially along the cable shaft 1. Each folding arm 26 can be a polygonal telescopic structure, such as a parallelogram telescopic structure. By pushing the end of the folding arm 26 away from the cable shaft 1 towards the direction closer 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, thereby changing the folding arm 26 into a folded state (e.g., ...). Figure 6(See the attached diagram on the right). Pulling the end of the folding arm 26 away from the cable spool 1 further away increases the distance between this end and the cable spool 1, thus changing the folding arm 26 into an unfolded state. Therefore, by adopting the above method, the distance between the end of the folding arm 26 away from the cable spool 1 and the cable spool 1 can be changed to accommodate variations in the total radial thickness of the cable spool 1 occupied by different optical fibers coiled on it, achieving a good binding effect for different types of optical fibers.

[0073] This embodiment also provides a cable package, including: a cable reel as described in any of the preceding claims, and a cable on a cable spool wound around the cable reel.

[0074] This embodiment also provides an encapsulation structure, including: the cable encapsulation as described above, and an optical fiber terminal box or optical fiber information panel box on which the cable encapsulation is installed. In an exemplary embodiment, the cable encapsulation is installed inside the optical fiber terminal box. Taking optical fiber as an example, the optical fiber is coiled inside the cable reel of the cable encapsulation, and one end of the optical fiber is provided with an optical fiber connector. Different optical fiber connectors are connected through adapters. The cable reel is detachably installed inside the optical fiber terminal box.
