[0030] To solve the above problems, as Figure 1 , Figure 5 ,Figure 6 and Figure 7 As shown in Figure 7 , the utility model provides a multi-core tail cable storage device, which includes a cable storage box 1, a cable storage turntable 2, and an optical fiber adapter 4. The cable storage turntable 2 is arranged in the cable storage box 1. The cable storage turntable 2 includes a bushing 21, a first disk 22, and a second disk 23. A rotating shaft is provided on the bottom surface of the cable storage box 1. The bushing 21 is rotatably connected to the rotating shaft. The first disk 22 and the second disk 23 are sequentially sleeved on the circumferential side of the bushing 21 from top to bottom. A tail fiber box 61 is provided on the first disk 22. A plurality of the optical fiber adapters 4 are provided at the end of the tail fiber box 61. An inlet is formed on the tail fiber box 61. An inlet hole 111 and an outlet hole 112 are formed on the side wall of the cable storage box 1. A plurality of tail fibers 52 at the end of the tail cable 51 are used to be arranged in the tail fiber box 61. The tail cable 51 passes out of the tail fiber box 61 along the inlet. The plurality of tail fibers 52 are used to be respectively connected to one end of the plurality of optical fiber adapters 4. The tail cable 51 is used to be coiled around the bushing 21 between the first disk 22 and the second disk 23 and passes out of the cable storage box 1 along the outlet hole 112. The other ends of the plurality of optical fiber adapters 4 are used to be connected to the cables passing through the inlet hole 111.

[0031] In this embodiment, the cable storage box 1 is provided as a housing to protect the cable storage turntable 2 disposed inside the cable storage box 1. The cable storage turntable 2 is rotatably connected to the bottom surface of the cable storage box 1. A rotating shaft is provided on the bottom surface of the cable storage box 1, and a bushing 21 is sleeved on the periphery of the rotating shaft, so that the bushing 21 can rotate around the rotating shaft. A first disk 22 and a second disk 23 are sequentially sleeved on the periphery of the bushing 21 in the vertical direction. The first disk 22 is located above the second disk 23. An inlet hole 111 and an outlet hole 112 are further formed on the side wall of the cable storage box 1. A pigtail box 61 is provided on the first disk 22. An adapter mounting port 63 and an inlet are formed on the pigtail box 61. A plurality of optical fiber adapters 4 are connected to the end of the pigtail box 61. When storing the tail cable 51, the end of the tail cable 51 is inserted into the pigtail box 61 from the inlet of the pigtail box 61, so that a plurality of pigtails 52 at the end of the tail cable 51 are placed in the pigtail box 61 and are respectively connected to a plurality of optical fiber adapters 4, and are fixed on the cable storage turntable 2 through the optical fiber adapters 4. The pigtail box 61 protects the pigtails 52 and also provides an installation position for a plurality of optical fiber adapters 4.

The tail cable 51 extending out of the inlet of the pigtail box 61 is wound around the bushing 21 and coiled, and is wound between the first disk 22 and the second disk 23. The first disk 22 and the second disk 23 limit the tail cable 51 in the vertical direction to prevent the tail cable 51 from detaching from the bushing 21. After the tail cable 51 is wound around the bushing 21, it passes through the outlet hole 112 and exits the cable storage box 1. When wiring is required, the tail cable 51 outside the cable storage box 1 is dragged, and the tail cable 51 can be dragged according to the length of the tail cable 51 required. During this process, the cable storage turntable 2 rotates, and the tail cable 51 on the cable storage turntable 2 is pulled out of the cable storage box 1, which is convenient for connecting the end of the tail cable 51 to an external circuit. The utility model coils the tail cable 51 on the cable storage turntable 2, straightens the tail cable 51, and prevents the tail cable 51 from being wound. When wiring, it is convenient to find the joint of the tail cable 51, and a plurality of pigtails 52 branched from the tail cable 51 are respectively inserted into a plurality of optical fiber adapters 4, which is convenient for distinguishing a plurality of pigtails 52 during wiring, improving the connection accuracy and making the wiring operation simpler.

A plurality of the optical fiber adapters 4 are inserted into the adapter mounting port 63. The pigtail cover 62 is covered on the pigtail box 61.

[0033] In this embodiment, by providing a fiber optic cable cover 62 that is used in conjunction with the fiber optic cable box 61, and by opening an adapter installation opening 63 at the end of the fiber optic cable box 61, a plurality of fiber optic adapters 4 are plugged onto the fiber optic cable box 61 through the adapter installation opening 63. When storing the tail cable 51, first open the fiber optic cable cover 62, insert the end of the tail cable 51 into the inlet of the fiber optic cable box 61 so that the plurality of fiber optic cables 52 at the end of the tail cable 51 are placed inside the fiber optic cable box 61 and are respectively connected to the plurality of fiber optic adapters 4. The tail cable 51 extending from the inlet of the fiber optic cable box 61 is wound around the bushing 21. At this time, the fiber optic cable cover 62 can be covered on the fiber optic cable box 61. The fiber optic cable cover 62 and the fiber optic cable box 61 cooperate to protect the fiber optic cable 52 and also provide an installation position for the plurality of fiber optic adapters 4.

[0034] Specifically, the roots of the plurality of fiber optic cables 52 can be tied together using cable ties. The size of the cable tie winding is larger than the size of the inlet, which plays a limiting role to prevent the tail cable 51 from pulling the fiber optic cables 52 out of the fiber optic cable box 61. The fiber optic adapter 4 can be an LC adapter.

[0035] Optionally, as Figures 7 to 8 shown, a plurality of positioning posts 64 are provided at the bottom of the fiber optic cable box 61, and a plurality of positioning holes 221 corresponding to the positioning posts 64 are opened on the first disk 22.

When the slider 162 is aligned with the slot 231, the fiber optic adapter 4 on the fiber optic cable box 61 is aligned with the inlet hole 111.

[0038] In this embodiment, an operation hole is formed in the side wall of the cable storage box 1, and a slideway 161 is arranged on the surface of the cable storage box 1. The slideway 161 communicates with the operation hole. A slider 162 is embedded in the slideway 161. The slider 162 can slide in the slideway 161. It can be manually passed through the operation hole to drive the slider 162 to slide in the slideway 161. A slot 231 is formed at the edge of the second disc 23. The shape of the slot 231 is the same as the shape of one end of the slider 162 facing the inside of the cable storage box 1. When the tail cable 51 is pulled out of the cable storage box 1, the cable storage turntable 2 is driven to rotate. When the cable storage turntable 2 rotates to align the optical fiber adapter 4 thereon with the inlet hole 111, the slideway 161 just aligns with the slot 231 on the second disc 23. At this time, the slider 162 is manually driven to insert into the slot 231, so that one end of the slider 162 is in the slot 231 and the other end is in the slideway 161. The slider 162 prevents the second disc 23 from continuing to rotate, limits the cable storage turntable 2, and facilitates the external cable to pass through the inlet hole 111 and be connected to the optical fiber adapter 4.

Two groove structures 122 for plugging and matching with the flange structure 132 are formed on the hole wall of the shaft hole along its circumferential direction. The flange structure 132 is used to move between the two groove structures 122. The central angle corresponding to the hole wall between the two groove structures 122 is between 95 degrees and 105 degrees.

[0042] In this embodiment, by providing a flange structure 132 on the circumferential side of the rotating shaft 131 and providing two groove structures 122 corresponding to the flange structure 132 on the hole wall of the circumferential section of the shaft hole, the flange structure 132 can be embedded in the groove structure 122.
