[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] like Figures 1 to 6As shown, the present application provides a cable winding unit, which specifically includes a spool assembly 21 and an adapter mounting member 22, wherein: the spool assembly 21 is used to wind up the optical cable; the adapter mounting member 22 is connected to the spool assembly 21, so that it can rotate synchronously with the spool assembly 21 under the drive of the spool assembly 21, and the adapter mounting member 22 is preferably connected to the upper end of the spool assembly 21, and the bottom of the spool assembly 21 is rotated to match the central axis 3 in subsequent use, and the adapter mounting member 22 can also be connected to the lower end of the spool assembly 21, and the top of the spool assembly 21 is rotated to match the central axis 3 in subsequent use, in order to facilitate winding up the optical cable and fixing the optical cable. A cable splitter and / or storing branch cables, a second storage area 2128 is provided on one side of the spool assembly 21 close to the adapter mounting part 22, and at the same time, the adapter mounting part 22 is provided with at least one adapter mounting interface 221, which is used to extend the branch cable connecting end 231 of each adapter 23 from the adapter mounting interface 221 into the interior of the adapter mounting part 22 to achieve the installation and fixation of the adapter 23, so that the branch cable connecting end of the adapter 23 is placed on the inner side of the adapter mounting part 22, thereby using the adapter mounting part 22 to completely cover the internal wiring of the branch cable, ensuring that no internal wiring can be seen from the outside, which has the advantage of being neat and beautiful.

[0048] Furthermore, the adapter installation interface 221 can be opened on the side wall of the adapter installation part 22, but when the number of adapters 23 is greater than 1, this arrangement will cause the household end connectors 232 of the adapter 23 to face different directions, making it inconvenient to unplug the household cable. Therefore, the adapter installation structure of the adapter installation part 22 preferably adopts a stepped structure or an I-shaped structure, and the adapter installation interface 221 is opened on the side wall of the upper step of the stepped structure, or on the concave side wall of the I-shaped structure, so that the household end connectors 232 of the adapter 23 can face the same direction, which is convenient for subsequent cable unplugging. For example, Figure 4 It is a schematic diagram showing that the adapter mounting structure of the adapter mounting member 22 is a stepped structure.

[0049] Furthermore, at least one first storage area 222 is provided inside the adapter mounting member 22 for storing branch optical cables and fixing the optical cable splitter. The first storage area 222 may be formed by vertical plates spaced from inside to outside, or may be formed by vertical plates spaced from inside to outside. Figure 5 As shown, it is composed of a winding plate 224 and a plurality of first baffles 225. The winding plate 224 forms an annular structure for storing branch cables. The first baffles 225 are circumferentially arranged on the outside of the winding plate 224 to prevent the branch cables from spreading out. At the same time, holes can be opened on the winding plate 224, and cable ties can be passed through the holes to connect the optical cable splitter to the winding plate 224 to fix the optical cable splitter.

[0050] Furthermore, the spool assembly 21 includes a winding post 211 and a first limiting member 212 and a second limiting member 213 respectively connected to the upper end and the lower end of the winding post 211. The winding post 211 is used to wind the optical cable for cable storage; the first limiting member 212 and the second limiting member 213 cooperate to form a accommodating space for the optical cable, which is used to limit the upper and lower positions of the optical cable wound on the outside of the winding post 211 to prevent it from spreading; the first limiting member 212 and the second limiting member 213 can be an integrated annular structure. From the perspective of ease of processing, the first limiting member 212 and the second limiting member 213 can also be respectively composed of at least two blades arranged at intervals, and the blades of the first limiting member 212 and the second limiting member 213 are staggered in the vertical direction; the upper surface or the lower surface of the first limiting member 212 is provided with at least one second storage area 2128 for storing optical cables, and can also be used to fix the optical cable brancher and store the branch cable, wherein Figure 3 is a schematic diagram showing that the second storage area 2128 is located on the upper surface of the first limiting member 212. Fig.14 Schematic diagram of the second storage area 2128 being located on the lower surface of the first stopper 212. In practical applications, the optical cable splitter can be fixed on the first stopper 212 or on the adapter mounting member 22 as required, preferably fixed on the upper surface of the first stopper 212.

[0051] The second storage area 2128 can be formed between the winding post 211 and the vertical plate or between multiple vertical plates by setting one or more vertical plates at intervals on the first limiting member 212. For example, the second storage area 2128 can be formed by setting a second baffle 2124 on the outer side of the winding post 211, or by setting vertical plates at intervals on the first limiting member 212 and forming the second storage area 2128 by utilizing the gaps between the vertical plates. The second storage area 2128 can also be formed by setting a vertical plate at the edge of the first limiting member 212 and setting a second baffle 2124 on the inner side of the vertical plate.

[0052] In a preferred embodiment of the present application, Figure 3As shown, the first stopper 212 is composed of three spaced fan-shaped blades, so the vertical plates are arc-shaped and are respectively arranged on the upper surface 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 the space between the first vertical plate 2125 and the winding post 211 forms a second storage area 2128, which can be used to store optical cables, and a plurality of second baffles 2124 are arranged on the inner side of the first vertical plate 2125, and a plurality of second baffles 2124 are arranged on the outer side of the winding post 211 to prevent the stored optical cables from being scattered. Open; the gap between the first vertical plate 2125 and the second vertical plate 2126 also forms a second storage area 2128, which can be used for storing optical cables, fixing splitters or storing branch cables, and a plurality of second baffles 2124 are respectively provided on the inner and outer sides of the second vertical plate 2126; the third vertical plate 2127 is arranged at the edge of the first limiting member 212, and the space between the second vertical plate 2126 and the third vertical plate 2127 also forms a second storage area 2128, which can be used for storing optical cables or storing branch cables, and a plurality of second baffles 2124 are provided on the inner side thereof, which can prevent the stored optical cables or branch cables from spreading.

[0053] Further, the first stopper 212 is connected to the adapter mounting member 22 by a hinge structure, a bolt structure or a snap-fit ​​structure, so that the adapter mounting member 22 can rotate synchronously with the spool assembly 21. Preferably, the first stopper 212 is hinged to one end of the adapter mounting member 22, so that the adapter mounting member 22 can be flipped up and down relative to the first stopper 212. In practical applications, any hinge structure can be used to connect the first stopper 212 to the adapter mounting member 22, for example, Figure 1 As shown, two first hinged members 2129 extending upward are symmetrically arranged on the first limiting member 212, and a through hole with an opening on one side is opened on the top of the first hinged member 2129. At the same time, a first hinge shaft 227 is arranged inside the adapter mounting member 22. During assembly, the first hinge shaft 227 is squeezed into the through hole of the first hinged member 2129, so that the adapter mounting member 22 can rotate relative to the first limiting member 212 with the first hinge shaft 227 as the axis.

[0054] Furthermore, the side wall of the first limiting member 212 is provided with at least one limiting boss or at least one limiting groove along the circumferential direction, and the inner wall of the adapter mounting member 22 is provided with at least one limiting groove or at least one limiting boss along the circumferential direction, and the fixing connection between the spool assembly 21 and the adapter mounting member 22 is achieved by matching the limiting boss with the limiting groove. For example, Figure 3As shown, at least one first limiting boss 2121 is circumferentially spaced apart on the side wall of the first limiting member 212, and at least one first limiting groove 223 is circumferentially spaced apart on the inner wall of the adapter mounting member 22. The first limiting boss 2121 is embedded and matched with the first limiting groove 223 to realize a fixed connection between the spool assembly 21 and the adapter mounting member 22.

[0055] The first stopper 212 is provided with at least one buckle extending upward or at least one mounting hole, and the adapter mounting member 22 is provided with at least one mounting hole or at least one buckle extending downward at a corresponding position, and the adapter mounting member 22 is fixedly connected to the spool assembly 21 by the buckle and the mounting hole. Exemplarily, at least one first buckle 2123 extending upward is provided at the top of the first stopper 212, and the adapter mounting member 22 is provided with a first mounting hole 226 at a position corresponding to the first buckle 2123, which is used to pass through the first buckle 2123 and cooperate with the first buckle 2123 to realize the fixed connection between the adapter mounting member 22 and the spool assembly 21.

[0056] In order to achieve a fixed connection between the spool assembly 21 and the adapter mounting member 22, any one of the above two connection methods may be adopted, or both may be adopted.

[0057] Furthermore, more than two support columns 228 are provided on the inner side of the adapter mounting part 22. The support columns 228 are located directly above the winding post 211 and play a supporting role by abutting against the winding post 211 to prevent the adapter mounting part 22 from being excessively recessed when the adapter mounting part 22 is pressed downward.

[0058] According to another aspect of the present application, Figure 7 , 8 As shown, a fiber storage device is provided, which specifically includes a central axis 3, a base 5 and the above-mentioned cable winding unit 2. The central axis 3 is arranged on the base 5. The central axis 3 can be a separate component or can be integrally formed with the base 5. The spool assembly 21 is rotatably matched with the central axis 3. Preferably, the middle opening of the spool assembly 21 is rotatably matched with the central axis 3. It is preferably sleeved on the outside of the central axis 3 so that the spool assembly 21 can rotate around the central axis 3 to realize the pulling function of the optical cable. During use, the optical cable can be wound on the fiber storage assembly 21, and the optical cable can be pulled as needed during construction. The spool assembly 21 rotates around the central axis 3 to release an optical cable of a suitable length.

[0059] Furthermore, at least one second buckle 31 and at least one third buckle 32 are provided at the top of the central shaft 3, and the second buckle 31 and the third buckle 32 are spaced apart in the circumferential direction. A first protrusion 311 is protrudingly provided on the outer wall surface of the second buckle 31, and a second protrusion 321 is protrudingly provided on the outer wall surface of the third buckle 32. The distance between the first protrusion 311 and the base 5 is smaller than the distance between the second protrusion 321 and the base 5. A first connecting position is formed between the top surface of the first protrusion 311 and the bottom surface of the second protrusion 321, and a second connecting position is formed on one side of the bottom surface of the first protrusion 311. At the same time, a ring plate 2111 of a certain thickness is provided on the inner wall of the hole of the winding column 211 along the circumferential direction. The ring plate 2111 can be self-embedded in the first connecting position or the second connecting position. When the ring plate 2111 is self-embedded in the second connecting position, the spool assembly 21 is in axial locking, and when the ring plate 2111 is self-embedded in the first connecting position, the spool assembly 21 is in axial locking and circumferential locking.

[0060] Furthermore, the fiber storage device also includes an annular baffle 4, which is arranged on the base 5 and located on the outside of the spool assembly 21 to form a accommodating cavity for the optical cable on the base 5 to prevent the optical cable from spreading outward. At the same time, at least one cable outlet groove 41 is opened on the annular baffle 4 for leading out the optical cable to facilitate pulling the optical cable.

[0061] To facilitate pulling, the diameter of the first limiting member 212 needs to be slightly smaller than the diameter of the annular baffle 4. Accordingly, in order to limit the optical cable in the vertical direction and prevent it from loosening from the gap between the first limiting member 212 and the annular baffle 4, a plurality of second limiting bosses 2122 are arranged on the side wall of the first limiting member 212 at intervals along the circumferential direction. The second limiting bosses 2122 cooperate with the gap of the annular baffle 4 to limit the optical cable.

[0062] Furthermore, the side wall of the adapter mounting member 22 is circumferentially provided with at least one limiting boss or at least one limiting groove, and the top end of the annular baffle 4 is circumferentially provided with at least one limiting groove or at least one limiting boss, and the circumferential locking of the adapter mounting member 22 and the annular baffle 4 is achieved by the embedded matching of the limiting boss and the limiting groove.

[0063] For example, Figure 8 As shown, the side wall of the adapter mounting member 22 is provided with a plurality of third limiting bosses 229 at intervals along the circumferential direction, and the top end of the annular baffle plate 4 is provided with a plurality of second limiting grooves 42 at intervals along the circumferential direction, and the third limiting bosses 229 are embedded and matched with the second limiting grooves 42 to realize the circumferential locking of the adapter mounting member 22 and the annular baffle plate 4.

Preferably, the bottom of the spool assembly 21 has a hole and is rotatably matched with the central axis 3, and is preferably sleeved on the outside of the central axis 3, so that the spool assembly 21 can rotate around the central axis 3, thereby realizing the pulling function of the optical cable. The axial locking of the spool assembly 21 and the central shaft 3 and the axial locking method can refer to the above-mentioned fiber storage device.

[0065] Furthermore, the terminal box further comprises an annular baffle 4, which is arranged on the second housing 12 and located outside the spool assembly 21, and at least one outlet groove 41 is provided on the annular baffle 4. The structural optimization of the annular baffle 4 and the circumferential locking method with the adapter mounting member 22 can refer to the above-mentioned fiber storage device. Preferably, in order to ensure smooth pulling of the first optical cable, the outlet groove 41 and the first cable outlet 121 are arranged in the same line along the outlet direction of the first optical cable.

[0066] According to another aspect of the present application, a terminal box is provided, specifically comprising a housing 1 and the above-mentioned fiber storage device, wherein: the housing 1 comprises a first shell 11 and a second shell 12, the first shell 11 and the second shell 12 constitute a receiving cavity, the second shell 12 is provided with at least one first cable outlet 121 and at least one second cable outlet 122, the first cable outlet 121 is used to pass through the first optical cable, and the second cable outlet 122 is used to pass through the second optical cable; the fiber storage device is located in the receiving cavity, and the base 5 of the fiber storage device is connected to the second shell 12. Preferably, in order to ensure smooth pulling of the first optical cable, the cable outlet groove 41 and the first cable outlet 121 are arranged in the same line along the outlet direction of the first optical cable.

[0067] This application further optimizes the two terminal boxes to adapt to various application environments. For example:

[0068] One end side wall of the first shell 11 is connected to one end side wall of the second shell 12 through a built-in hinge structure, and the other end side wall of the first shell 11 is detachably fixedly connected to the other end side wall of the second shell 12, thereby ensuring that there is no fixed structure on the upper surface of the first shell 11, and the overall appearance is neat and beautiful. For example, Fig.13As shown, a second hinge 112 extending downward is provided on the inner side of the side wall at one end of the first shell 11. The second hinge 112 is provided with a through hole with an opening on one side. At the same time, a second hinge shaft 127 extending outward is provided on the side wall at one end of the second shell 12. During assembly, the second hinge shaft 127 is squeezed into the through hole of the second hinge 112. At the same time, a connecting piece 111 is embedded in the side wall at the other end of the first shell 11. Correspondingly, a connecting hole 123 is opened on the side wall at the other end of the second shell 12.
