Specific embodiments

[0017] For a better understanding of the objects, technical solutions, and advantages of the present application, a further detailed description of the present application follows in conjunction with the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein serve only to illustrate the application and are not intended to limit the application.

[0018] As in the Fig. 1 to 6, the present application provides a coil cable unit, specifically comprising a coil assembly 21 and an adapter mounting bracket 22. The coil assembly 21 is used for coil storage of the fiber optic cables. The adapter mounting bracket 22 is connected to the coil assembly 21 so that it can be rotated synchronously with the coil assembly 21 under the drive of the coil assembly 21. The adapter mounting bracket 22 is preferably connected to the upper end of the coil assembly 21. In later use, the bottom of the coil assembly 21 is rotatably adapted to the central shaft 3. At the same time, the adapter mounting bracket 22 may also be connected to the lower end of the coil assembly 21. In later use, the top of the coil assembly 21 is rotatably adapted to the central shaft 3.For spool storage of fiber optic cables, fixing the branching of the fiber optic cables, and spool storage of fiber optic drop cables, a second spool storage area 2128 is arranged on the side near the adapter mounting bracket 22 on the spool assembly 21. At the same time, the adapter mounting bracket 22 has at least one adapter mounting bracket interface 221 for extending a drop cable connection end 231 of each adapter 23 from the adapter mounting bracket interface 221 into an interior of the adapter mounting bracket 22 for mounting and securing the adapter 23, so that the drop cable connection end of the adapter 23 is placed on the inside of the adapter mounting bracket 22, thereby completely covering the internal wiring of the drop cable with the adapter mounting bracket 22, ensuring that no internal wiring is visible from the outside, which has the advantage of being clean and beautiful.

[0019] Furthermore, the adapter mounting interface 221 can be provided on the side wall of the adapter mounting bracket 22. However, if the number of adapters 23 is greater than 1, this arrangement may cause the connector at the house entrance 232 of the adapter 23 to point in different directions, making it inconvenient for the input cable to spread out. Therefore, the adapter mounting structure of the adapter mounting bracket 22 preferably adopts a stepped structure or an I-shaped structure, and the adapter mounting interface 221 is provided on the upper step side wall of the stepped structure or on the inner concave side wall of the I-shaped structure so that the connector at the house entrance 232 of the adapter 23 can be oriented in the same direction to facilitate subsequent cable withdrawal. For example, Fig. 4 is a schematic representation of the adapter mounting structure of the adapter mounting bracket 22 as a stepped structure.

[0020] Furthermore, the inside of the adapter mounting bracket 22 is provided with at least one first coil storage area 222 for coil storage of the fiber optic branch cable and can also be used to fix the branch of the fiber optic cable. The first coil storage area 222 may consist of a vertical plate arranged at intervals from the inside to the outside, or it may consist of a winding plate 224 and a plurality of first blocking pieces 225, as shown in Fig. 5.

The first stopper 212 cooperates with the second stopper 213 to form a receiving cavity for the fiber optic cable and an upper and lower limit for preventing the fiber optic cable from spreading outside the winding post 211, respectively. The first stopper 212 and the second stopper 213 may be a one-piece annular structure.From the viewpoint of facilitating processing, the first stopper 212 and the second stopper 213 may also be composed of at least two interval blades, and the blades of the first stopper 212 and the second stopper 213 are offset in the vertical direction; the upper or lower surface of the first stopper 212 is provided with at least one second spool storage portion 2128 for spool storage of the optical fiber cable, fixing of the branch of the optical fiber cable, and spool storage of optical fiber branch cables, wherein. Fig. 3 is a schematic view of the second coil storage area 2128 on the upper surface of the first stop piece 212 and Fig. 14 is a schematic view of the second coil storage area 2128 on the lower surface of the first stop piece 212. In practical applications, the branch of the fiber optic cable may be attached to the first stop piece 212 or to the adapter mounting bracket 22, as desired, preferably to the upper surface of the first stop piece 212.

[0022] It may be formed by arranging one or more spaced vertical plates on the first stop piece 212 to form a second coil storage area 2128 between the winding post 211 and the vertical plate or between the plurality of vertical plates. For example, the second coil storage area 2128 may be formed by arranging the second blocking piece 2124 on the outside of the winding post 211, or may be formed by arranging a plurality of spaced vertical plates on the first stop piece 212 or to form the second coil storage area 2128 with gaps between the vertical plates, or may be possible by arranging vertical plates on the edge of the first stop piece 212 and on the inside of vertical plates by arranging the second blocking piece 2124 to form the second coil storage area 2128.

[0023] In a preferred embodiment of the present application, as in Fig. 3, the first stop piece 212 consists of three spaced fan-shaped blades such that the vertical plates have an arcuate structure and are respectively arranged on the top of each fan-shaped blade, and each fan-shaped blade is sequentially spaced from the inside to the outside with a first vertical plate 2125, a second vertical plate 2126, and a third vertical plate 2127, wherein in the space between the winding post 211 and the first vertical plate 2125, a second spool storage area 2128 is formed, which can be used for spool storage of the fiber optic cable, and the inside of the first vertical plate 2125 is provided with a plurality of second blocking pieces 2124, wherein the outside of the winding post 211 is provided with a plurality of second blocking pieces 2124 to prevent stored fiber optic cables from scattering;The gap between the first vertical plate 2125 and the second vertical plate 2126 also forms a second coil storage area 2128, which can be used for coil storage of fiber optic cables, fixing of the branch of the fiber optic cables, and coil storage of fiber optic branch cables. The inside and outside of the second vertical plate 2126 are each provided with a plurality of second blocking pieces 2124; the third vertical plate 2127 is arranged at the edge of the first stop piece 212, and the space between the second vertical plate 2126 and the third vertical plate 2127 also forms a second reel storage area 2128, which can be used for reel storage of fiber optic cables or fiber optic drop cables, and its inside is provided with a plurality of second blocking pieces 2124, which can prevent the stored fiber optic cables or drop cables from spreading.;

[0024] Furthermore, the first stop piece 212 is connected to the adapter mounting bracket 22 by a hinge structure, a bolt structure, or a buckle structure so that the adapter mounting bracket 22 can rotate synchronously with the spool assembly 21. Preferably, the first stop piece 212 is hinged to one end of the adapter mounting bracket 22 so that the adapter mounting bracket 22 can be folded up and down relative to the first stop piece 212. In practical applications, any hinge structure can be used to connect the first stop piece 212 to the adapter mounting bracket 22. For example, as shown in Fig. 1, the first stop piece 212 is symmetrically provided with two upwardly extending first hinges 2129, the top of the first hinge 2129 has a lateral through-hole, the interior of the adapter mounting bracket 22 is provided with a first hinge shaft 227, and the first hinge shaft 227 is squeezed into the through-hole of the first hinge 2129 during assembly, so that the adapter mounting bracket 22 with the first hinge shaft 227 can rotate relative to the first stop piece 212.

[0026] The first stopper 212 is provided with at least one upwardly extending buckle or at least one fixing hole, and the adapter mounting bracket 22 is provided with at least one fixing hole or at least one downwardly extending buckle at a corresponding position. The fixed connection between the adapter mounting bracket 22 and the spool assembly 21 is realized by attaching the buckle to the fixing hole. For example, the upper end of the first stopper 212 is provided with at least one upwardly extending first buckle 2123, while the adapter mounting bracket 22 is provided with a first fixing hole 226 at a position corresponding to the first buckle 2123 to pass through the first buckle 2123 and mate with the first buckle 2123 to securely connect the adapter mounting bracket 22 to the spool assembly 21.

[0027] To achieve a firm connection between the coil assembly 21 and the adapter mounting bracket 22, either one or both of the above two connection methods may be used.

[0028] Furthermore, the inside of the adapter mounting bracket 22 is provided with more than two support columns 228, wherein the support columns 228 are arranged directly above the winding posts 211 and play a supporting role by abutting against the winding posts 211 to prevent excessive depression of the adapter mounting bracket 22 when the adapter mounting bracket 22 is depressed.

[0029] According to another aspect of the present application, as described in the Fig. 7 and Fig. 8, a fiber storage device is provided, which specifically comprises a central shaft 3, a base 5, and the above-mentioned spool cable unit 2.
