Description

Technical Field

[0001] This application relates to the field of optical fiber and cable packaging equipment technology, and in particular to a pre-terminated optical cable packaging reel. Background Technology

[0002] The core advantages of pre-terminated optical cables lie in their rapid deployment, high reliability, and environmental adaptability, and they are widely used in data centers, 5G communications, and device interconnection.

[0003] Traditional pre-terminated optical cables are typically packaged in simple bundles or on traditional optical cable reels. Of these packaging methods, simple packaging is generally suitable for optical cables with a diameter less than 5mm, such as pre-terminated MPO optical cables and pre-terminated butterfly optical cables. Using optical cable reels is typically suitable for situations where the inner end of the optical cable is not terminated or is terminated but without any protruding sub-cables.

[0004] As the application fields of pre-terminated optical cables continue to expand, some application scenarios of pre-terminated optical cables require multi-core bundled optical cables or branch optical cables with a wire diameter greater than 5mm, and the two ends of the optical cable have a certain length of branch cables. For example, pre-terminated flexible straight optical cables and pre-terminated ultra-high voltage optical cables cannot be wound in diameter at the innermost end of the optical cable reel because the pressure resistance of the branch cables is insufficient.

[0005] It is evident that traditional simple packaging methods and optical cable reel packaging methods are not suitable for the pre-terminated optical cables with the above-mentioned structure. The pre-terminated optical cable manufacturing industry urgently needs a new type of packaging for pre-terminated optical cables to solve the above problems. Summary of the Invention

[0006] This application provides a pre-terminated optical cable packaging reel to solve the problem that the pre-terminated optical cable packaging method in the related art is not suitable for pre-terminated optical cables with a wire diameter greater than 5mm, a multi-core bundle or branch optical cable structure, and a certain length of sub-cables extending from the end-terminated portions.

[0007] This application provides a pre-terminated optical cable packaging reel, which includes:

[0008] A cylindrical body, wherein one end of the cylindrical body is provided with a sealing plate and the other end is an open end;

[0009] The inner cable winding section has one end installed in the middle of the sealing plate and located inside the cylinder;

[0010] An outer cable winding section, one end of which is installed on the sealing plate, is sleeved on the outside of the inner cable winding section and located inside the cylinder, so as to divide the space between the cylinder and the inner cable winding section into an inner cable storage area and an outer cable storage area.

[0011] In addition, the outer cable winding section is provided with a communication port connecting the inner cable storage area and the outer cable storage area.

[0012] In some embodiments, two connection ports are provided.

[0013] In some embodiments, the outer cable winding portion includes two arc-shaped plates arranged at intervals to form a communication port between the ends of the arc-shaped plates.

[0014] In some embodiments, the two connecting ports are symmetrically arranged on the outer cable winding portion.

[0015] In some embodiments, the open end is detachably provided with an end cap.

[0016] In some embodiments, a handle is provided on the outer wall of the cylinder.

[0017] In some embodiments, the pre-assembled optical cable packaging reel further includes a rotating table, and the bottom of the sealing plate is disposed on the rotating table.

[0018] In some embodiments, the rotary table is fixedly connected to the sealing plate, or is detachably connected.

[0019] In some embodiments, the inner cable winding section is a cylindrical tube.

[0020] In some embodiments, the outer diameter of the cylinder is 200mm to 2000mm, and the height is 50mm to 1000mm.

[0021] The beneficial effects of the technical solution provided in this application include:

[0022] The pre-terminated optical cable packaging reel provided in this application provides an outer layer cable winding section, which divides the space between the cylinder and the inner layer cable winding section into an inner layer cable storage area and an outer layer cable storage area. This forms an inner layer cable storage area with the inner layer cable winding section as the winding post and an outer layer cable storage area with the outer layer cable winding section as the winding post. By providing a connecting port to connect the inner layer cable storage area and the outer layer cable storage area, the boundary point between the inner and outer layer lengths of the optical cable can be transitioned. Then, the cable is wound on the inner layer cable storage area and the outer layer cable storage area respectively, so that the end portions of the optical cable at both ends can be wound to the top layer of the packaging reel. This makes it suitable for packaging pre-terminated optical cables with a wire diameter greater than 5mm, a multi-core bundle or branch optical cable structure, and a certain length of branch cable extending from the end portions at both ends.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] See Figure 1 , Figure 2 and Figure 3 As shown in the figure, this application provides a pre-assembled optical cable packaging reel, which includes a cylindrical body 100, an inner cable winding section 200, and an outer cable winding section 300. One end of the cylindrical body 100 is provided with a sealing plate 101, and the other end is an open end. One end of the inner cable winding section 200 is installed in the middle of the sealing plate 101 and is located inside the cylindrical body 100. One end of the outer cable winding section 300 is installed on the sealing plate 101. The outer cable winding section 300 is sleeved on the outside of the inner cable winding section 200 and is located inside the cylindrical body 100, so as to divide the space between the cylindrical body 100 and the inner cable winding section 200 into an inner cable storage area 102 and an outer cable storage area 103. The outer cable winding section 300 is provided with a communication port 301 connecting the inner cable storage area 102 and the outer cable storage area 103.

[0031] The materials of each component in the pre-assembled optical cable packaging reel are not limited, including but not limited to metal, wood, paper, plastic, etc.

[0032] Given the requirements for pre-terminated optical cable preparation and construction, and considering that the branch cables of some pre-terminated optical cables have a certain length and cannot be compressed, the termination sections at both ends of the optical cable need to be wound to the top layer of the packaging reel. Under this premise, when using the pre-terminated optical cable packaging reel provided in this application embodiment, the optical cable is first cut to the specified length according to actual needs, and the length of the optical cable to be wound to the inner cable storage area 102 and the outer cable storage area 103 of the packaging reel is determined according to the application requirements of the optical cable. Then, the dividing point between the inner and outer lengths of the optical cable is transitioned to the bottom of the opening of the packaging reel. The optical cable to be wound to the inner cable storage area 102 and the outer cable storage area 103 of the packaging reel is then wound onto the inner cable winding part 200 and the outer cable winding part 300, respectively. The subsequent sealing operation completes the pre-terminated optical cable packaging process.

[0033] As can be seen, the pre-terminated optical cable packaging reel provided in this application provides an outer layer cable winding section 300, which divides the space between the cylinder 100 and the inner layer cable winding section 200 into an inner layer cable storage area 102 and an outer layer cable storage area 103. This forms an inner layer cable storage area 102 with the inner layer cable winding section 200 as the winding post and an outer layer cable storage area 103 with the outer layer cable winding section 300 as the winding post. By providing a connecting port 301 to connect the inner layer cable storage area 102 and the outer layer cable storage area 103, the boundary point between the inner and outer layers of the optical cable can be transitioned. Then, the cable is wound on the inner layer cable storage area 102 and the outer layer cable storage area 103 respectively, so that the end portions of the optical cable at both ends can be wound to the top layer of the packaging reel. This makes it suitable for packaging pre-terminated optical cables with a wire diameter greater than 5mm, a multi-core bundle or branch optical cable structure, and a certain length of branch cable extending from the end portions at both ends.

[0034] See Figure 1 As shown, there are two connection ports 301. The advantages of having two connection ports 301 are twofold. First, it allows users to choose the appropriate orientation of the connection port 301 according to actual packaging requirements when packaging pre-assembled optical cables, providing users with multiple options. Second, with an additional connection port 301, the overall weight of the pre-assembled optical cable packaging reel can be further reduced, achieving a lightweight design while ensuring normal use.

[0035] See Figure 1 As shown, the outer cable winding section 300 includes two arc-shaped plates 302, which are arranged at intervals to form a communication port 301 between their ends. The two communication ports 301 are symmetrically arranged on the outer cable winding section 300.

[0036] It is understood that the outer cable winding portion 300 of this application may include a plurality of posts, which are distributed in a circular pattern on the outside of the inner cable winding portion 200, and the communication port 301 may be formed between two adjacent posts.

[0037] Compared to setting up multiple columns in a circular distribution, this embodiment uses an arc-shaped plate 302 design. The advantage of this design is that, compared to the multiple assembly operations required for each column, the two arc-shaped plates 302 only require two operations to complete the assembly, making it more convenient.

[0038] To protect the packaged pre-terminated optical cables from damage during transport, see [link to relevant documentation]. Figure 1 As shown in the embodiment of this application, an end cap 400 is also provided, wherein the open end is detachably provided with an end cap 400.

[0039] For example, the end cap 400 is fastened to the open end; for example, the outer wall of the open end is provided with external threads, and the inner wall of the end cap 400 is provided with internal threads. By utilizing the matching relationship between the external and internal threads, the end cap 400 is threadedly connected to the open end; for example, the inner wall of the open end is provided with internal threads, and the outer wall of the end cap 400 is provided with external threads. By utilizing the matching relationship between the external and internal threads, the end cap 400 is threadedly connected to the open end.

[0040] For ease of handling and relocation, please refer to [reference needed]. Figure 1 As shown, a handle 500 is provided on the outer wall of the cylinder 100. Two handles 500 may be provided and symmetrically arranged on the outer wall of the cylinder 100.

[0041] To ensure that the optical cable is laid without over-twisting, please refer to... Figure 3 As shown, the pre-assembled optical cable packaging reel also includes a rotary table 600, and the bottom of the sealing plate 101 is disposed on the rotary table 600.

[0042] During the optical cable construction phase, in order to ensure that the optical cable is laid without over-twisting, the construction and laying process needs to be coordinated with the operation of a rotating table. That is, at the starting position of construction, the packaging reel containing the optical cable is placed on the rotating table, and one end of the pre-formed optical cable is manually pulled to lay the cable to the designated position. During this process, the packaging reel rotates on the rotating table by itself, thus completing the torsion-free laying process.

[0043] The rotary table 600 and the sealing plate 101 can be fixedly connected to form an integrated structure, or they can be detachably connected to form a split structure. Both the integrated structure installation and the split structure installation can adopt existing conventional solutions, which will not be elaborated here.

[0044] The design of the rotating table is not limited, but its function is to enable the packaging tray to rotate clockwise and counterclockwise in the horizontal direction to ensure that the optical cable is laid without over-twisting.

[0045] See Figure 2 As shown, the inner cable winding section 200 adopts a cylindrical tube. Compared with a solid column, the advantage of using a cylindrical tube is that it can achieve a lightweight design while ensuring normal use.

[0046] The outer diameter and height of the cylinder 100, the outer diameter of the outer cable winding section 300, and the outer diameter of the inner cable winding section 200 are set according to the length and diameter of the optical cable to be stored. The typical outer diameter L1 of the cylinder 100 is 200mm to 2000mm, and the typical height H is 50mm to 1000mm.

[0047] Example 1

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment provides a pre-terminated optical cable packaging reel. The diameter L1 of the cylindrical body 100 is 700mm, the height H is 300mm, the diameter L2 of the inner cable winding part 200 is 400mm, the inner cable winding part 200 is provided with two symmetrical 100mm wide connecting ports 301, and the diameter L3 of the outer cable winding part 300 is 200mm.

[0049] The cylinder 100 is made of kraft paper, the end cap 400 is a metal cover, and the rotary table 600 is designed as a separate structure from the cylinder 100. The rotary table 600 adopts a square steel frame with a symmetrical design at the top and bottom, and is connected in the middle by a high-speed bearing, supporting bidirectional rotation.

[0050] Taking a pre-terminated optical cable with a diameter of 13.5mm as an example, the outer cable storage area 103 of the above-mentioned packaging reel can hold 250m of optical cable, and the inner cable storage area 102 can hold 70m of optical cable.

[0051] During the fiber optic cable loading stage, the 320m fiber optic cable is first laid down to the 70m mark, where it transitions to the bottom of the packaging reel's connecting port 301. Then, the 70m and 250m fiber optic cables are wound from bottom to top into the inner cable storage area 102 and outer cable storage area 103 of the packaging reel, respectively. After these operations, one end of the 320m pre-terminated fiber optic cable is positioned on the top layer of the inner cable storage area 102, and the other end is positioned on the top layer of the outer cable storage area 103. Subsequent operations such as filling with cushioning material and sealing with end caps 400 complete the packaging of the pre-terminated fiber optic cable on this reel.

[0052] During the cabling construction phase, the starting position for laying out the cable is first determined. At this position, the packaging reel is placed on the rotary table 600. The end of the optical cable in the outer storage area 103 is manually pulled towards the designated position. During this process, the packaging reel rotates on the rotary table 600 under the influence of the cable tension. Reaching the designated position completes the horizontal cabling of the outer storage area 103. For the optical cable in the inner storage area 102, the end can be directly pulled for vertical laying according to application requirements. Alternatively, the inner storage area 102 can be removed for horizontal laying or other operations, thus completing the cabling construction.

[0053] Example 2

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides another pre-assembled optical cable packaging reel. The diameter L1 of the cylinder 100 is 700mm, the height H is 350mm, the diameter L2 of the inner cable winding part 200 is 400mm, the inner cable winding part 200 is provided with two symmetrical 100mm wide connecting ports 301, and the diameter L3 of the outer cable winding part 300 is 200mm.

[0055] The cylinder 100 is made of kraft paper, the end cap 400 is a metal cover, and the rotating platform 600 is designed as an integral structure with the cylinder 100. The base of the rotating platform adopts a circular frame, which is connected and fixed to the bottom of the packaging tray through high-speed bearings and tray assemblies.

[0056] Taking a pre-terminated optical cable with a diameter of 13.5mm as an example, the outer cable storage area 103 of the above-mentioned packaging reel can hold 250m of optical cable, and the inner cable storage area 102 can hold 70m of optical cable.

[0057] During the fiber optic cable loading stage, the 320m fiber optic cable is first laid down to the 70m mark, where it transitions to the bottom of the packaging reel's connecting port 301. Then, the 70m and 250m fiber optic cables are wound from bottom to top into the inner cable storage area 102 and outer cable storage area 103 of the packaging reel, respectively. After these operations, one end of the 320m pre-terminated fiber optic cable is positioned on the top layer of the inner cable storage area 102, and the other end is positioned on the top layer of the outer cable storage area 103. Subsequent operations such as filling with cushioning material and sealing with end caps 400 complete the packaging of the pre-terminated fiber optic cable on this reel.

[0058] During the cabling construction phase, the starting position for laying out the cable is first determined. At this position, the packaging reel is placed on the rotary table 600. The end of the optical cable in the outer storage area 103 is manually pulled towards the designated position. During this process, the packaging reel rotates on the rotary table 600 under the influence of the cable tension. Reaching the designated position completes the horizontal cabling of the outer storage area 103. For the optical cable in the inner storage area 102, the end can be directly pulled for vertical laying according to application requirements. Alternatively, the inner storage area 102 can be removed for horizontal laying or other operations, thus completing the cabling construction.
