[0055] In addition, the technical features involved in each embodiment of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0056] Embodiment 1:

[0057] Embodiment 1 of the present utility model provides an optical cable connection adapter applied to an optical cable reel, as Figure 1 shown, including: a housing box body 61, a first pair of interfaces 611, a second pair of interfaces 612, and a tensile member 65, where: the first pair of interfaces 611 is disposed on one side of the housing box body 61, and the first pair of interfaces 611 communicates the outside of the housing box body 61 with the inside of the housing box body 61; the first pair of interfaces 611 is used to connect to a first optical cable, and the optical fiber core and the strengthening rib 7 in the first optical cable are introduced into the housing box body 61 through the first pair of interfaces 611.

[0058] The second pair of interfaces 612 is disposed on the other side of the housing box body 61, and the second pair of interfaces 612 communicates the outside of the housing box body 61 with the inside of the housing box body 61; the second pair of interfaces 612 is used to connect to a second optical cable, and the optical fiber core and the strengthening rib 7 in the second optical cable are introduced into the housing box body 61 through the second pair of interfaces 612.

[0059] The inside of the housing box body 61 is used for coiling and docking the optical fiber cores of the first optical cable and the second optical cable; the tensile member 65 is respectively connected to the strengthening rib 7 of the first optical cable and the strengthening rib 7 of the second optical cable; wherein, the first optical cable and the second optical cable are any two different optical cables.

[0060] In this embodiment, the first optical cable and the second optical cable may refer to any two adjacent and sequentially connected optical cables accommodated on the fiber coiling part 3. It should be noted that each optical cable includes multiple fiber cores. The butt joint between different optical cables refers to the corresponding interconnection of the fiber cores in different optical cables. The butt joint between a single fiber core in one optical cable and a single fiber core in another optical cable enables the optical path connection between different optical cables.

[0061] In the existing optical cable design, in order to ensure that the optical cable has a certain toughness during actual use and storage, and will not cause damage to the internal fiber cores due to bending, one or more reinforcing ribs 7 with a certain toughness are provided in the optical cable. The reinforcing ribs 7 can be made of metal to ensure that the optical cable itself has a certain toughness. In this embodiment, in order to ensure the stability of the butt joint of two optical cables through the butt joint device 6, the reinforcing ribs 7 in the two optical cables are led out in the butt joint device 6 and are respectively connected to the two reinforcing ribs 7 through the tensile members 65. In this way, in addition to being butt-jointed through the butt joint device 6, the two optical cables are also connected through the respective reinforcing ribs 7 of the two optical cables and the tensile members 65, greatly enhancing the strength and stability of the butt joint between the optical cables. In this embodiment, the butt joint device 6 is the optical cable connection butt joint device applied to the optical cable reel.

[0062] In addition, it is worth mentioning that, as Figure 2 shown, if there are at least two reinforcing ribs 7 provided in a single optical cable, the butt joint device 6 includes at least two tensile members 65; one tensile member 65 is used to be respectively connected to one of the reinforcing ribs 7 of the first optical cable and one of the reinforcing ribs 7 of the second optical cable, and the other tensile member 65 is used to be respectively connected to the other reinforcing rib 7 of the first optical cable and the other reinforcing rib 7 of the second optical cable. Through the connection of the two tensile members 65, the butt joint strength is further enhanced.

[0063] In this embodiment, as Figure 3 shown, the following design is involved for the tensile member 65: The tensile member 65 specifically includes a base 651, a first screw 6522, a second screw 6532, a first nut 654, and a second nut 655, where: The first screw 6522 and the second screw 6532 are arranged on the base 651.

[0064] The first screw 6522 is used for the reinforcing rib 7 of the first optical cable to wind around. The first nut 654 is sleeved on the first screw 6522, and the first nut 654 is located above the reinforcing rib 7 wound on the first screw 6522. The first nut 654 is used to limit the reinforcing rib 7 wound on the first screw 6522.

[0065] The second screw rod 6532 is used for winding the strengthening ribs 7 of the second optical cable. The second nut 655 is sleeved on the second screw rod 6532. The second nut 655 is located above the strengthening ribs 7 wound on the second screw rod 6532. The second nut 655 is used to limit the strengthening ribs 7 wound on the second screw rod 6532.

[0066] In this embodiment, to further ensure the stability of the winding and fixation of the two strengthening ribs 7 on the screw rod, this embodiment also involves the following design: As Figure 4 and Figure 5 shown, the tensile member 65 further includes: a limiting plate 656, wherein: a third through hole 6561 and a fourth through hole 6562 are provided on the limiting plate 656; the third through hole 6561 is sleeved on the first screw rod 6522, and the fourth through hole 6562 is sleeved on the second screw rod 6532; the limiting plate 656 is located between the first nut 654 and the strengthening ribs 7 wound on the first screw rod 6522, and the limiting plate 656 is also located between the second nut 655 and the strengthening ribs 7 wound on the second screw rod 6532; the limiting plate 656 is used to limit the strengthening ribs 7 wound on the first screw rod 6522 and the strengthening ribs 7 wound on the second screw rod 6532.

[0067] In this embodiment, the installation method of the tensile member 65 is as follows: Wind and fix the strengthening ribs 7 of the two optical cables around the first screw rod 6522 and the second screw rod 6532 respectively. Insert the limiting plate 656 downward from the upper position of the base 651, and sleeve the third through hole 6561 and the fourth through hole 6562 around the first screw rod 6522 and the second screw rod 6532 respectively. At this time, the limiting plate 656 is above the strengthening ribs 7 wound around the first screw rod 6522 and the second screw rod 6532. Then sleeve the first nut 654 and the second nut 655 around the first screw rod 6522 and the second screw rod 6532 respectively, and through the cooperation of the first nut 654 and the second nut 655 with the first screw rod 6522 and the second screw rod 6532 respectively, press the first nut 654 and the second nut 655 above the limiting plate 656 respectively, so that the strengthening ribs 7 wound around the first screw rod 6522 and the second screw rod 6532 are stably pressed and fixed by the limiting plate 656; the stability of the tensile member 65 is improved.

[0068] On the other hand, since when actually docking two optical cables, a part of the fiber cores in the two optical cables need to be led out and docked, a corresponding storage box needs to be provided in the docking device 6 to store the fiber cores led out from the two docked optical cables, so as to avoid the chaotic placement of the fiber cores in the docking device 6. Therefore, this embodiment also involves the following settings: As Figure 6As shown, the adapter 6 further includes a fiber coiling box 64, and the fiber coiling box 64 is disposed in the outer shell 61; one end of the fiber coiling box 64 facing the first docking port 611 is provided with a first input port 641, and the first input port 641 is used to introduce the fiber core of the first optical cable introduced from the first docking port 611 into the interior of the fiber coiling box 64; one end of the fiber coiling box 64 facing the second docking port 612 is provided with a second input port 642, and the second input port 642 is used to introduce the fiber core of the second optical cable introduced from the second docking port 612 into the interior of the fiber coiling box 64; the interior of the fiber coiling box 64 is used for coiling and docking the fiber cores of the first optical cable and the second optical cable.

[0069] In this embodiment, the fiber cores of the first optical cable and the second optical cable are arranged in multiple turns of coiling in the fiber coiling box 64 and are docked at designated positions in the multiple turns of coiling. In this embodiment, corresponding limiting platforms may also be provided in the fiber coiling box 64 for limiting the fiber cores in the fiber coiling box 64 to enable the fiber cores to be coiled and stored according to a predetermined trajectory.

[0070] On the other hand, considering that after docking each section of the optical cable and in actual application scenarios, it is necessary to monitor the positions of each section of the docked optical cable for real-time state detection of the optical cable and the environment of the application scenario. Most of them are connected to the corresponding sensors and the fiber cores in the optical cable, and the transmission state of the optical signals in the fiber cores is detected for monitoring, so as to obtain the index parameters of the optical cable or the actual application scenario. Therefore, this embodiment also involves the following design: As Figure 6 shown, a sensor docking port 613 is further provided on the outer shell 61, and the sensor docking port 613 is used to dock with an external sensor, and the external sensor is used to connect with the fiber core of the first optical cable or the second optical cable in the outer shell 61. A first output port 643 is further provided on the fiber coiling box 64, and the first output port 643 is used to lead out the fiber core of the first optical cable or the second optical cable in the fiber coiling box 64 and connect it to the external sensor through the sensor docking port 613.

[0071] In this embodiment, since the sensor needs to be connected to at least one optical fiber core to detect the corresponding parameters of the optical signal in the optical cable, when every two optical cables are butted, at least one optical fiber core needs to be separated from the first optical cable and the second optical cable for leading out from the first output port 643 and being butted with an external sensor through the sensor docking interface 613. Therefore, in this embodiment, when every two optical cables are butted, at least one optical fiber core needs to be led out for docking with the sensor. As the optical cables are successively butted, at least one optical fiber core is fixedly led out and docked with the sensor each time of docking. The number of optical fiber cores for docking between subsequent optical cables decreases successively. Therefore, it is necessary to set the number of optical fiber cores in the optical cable according to the total number of required optical cables to ensure that while sensors are arranged at each docking position, there are enough optical fiber cores at all docking positions for butting between optical cables.

[0072] To illustrate the above design more clearly, the following example is given: In an actual application scenario, 5 optical cables need to be successively butted for operation. One optical fiber core is required for docking with the sensor at each docking position, and each optical fiber core is provided with 6 optical fiber cores. When the first optical cable and the second optical cable are butted, 5 optical fiber cores in the first optical cable and the second optical cable are correspondingly connected, and one optical fiber core is connected to the sensor. When the second optical cable and the third optical cable are butted, 4 optical fiber cores in the second optical cable and the third optical cable are correspondingly connected, and one optical fiber core is connected to the sensor. When the third optical cable and the fourth optical cable are butted, 3 optical fiber cores in the third optical cable and the fourth optical cable are correspondingly connected, and one optical fiber core is connected to the sensor. When the fourth optical cable and the fifth optical cable are butted, 2 optical fiber cores in the fourth optical cable and the fifth optical cable are correspondingly connected, and one optical fiber core is connected to the sensor.

[0073] It is worth mentioning that in order to prevent individual optical fiber cores in the optical cable from failing, a certain number of optical fiber cores can be reserved in the optical cable and are not connected between optical cables temporarily, nor are they used for docking with the sensor temporarily. They are only used as spare optical fiber cores when some working optical fiber cores fail.

[0074] Embodiment 2:

In order to show the internal fiber coiling part 3, part of the protective shell is hidden; the fiber coiling part 3 is used for coiling the optical cable on the side wall of the fiber coiling part 3; the first fiber guiding opening 11 is used for guiding the optical cable from the fiber coiling part 3 to the outside of the first disk surface 1 and docking with other optical cables; the second fiber guiding opening 21 is used for guiding the optical cable from the fiber coiling part 3 to the outside of the second disk surface 2 and docking with other optical cables.

[0080] In this embodiment, since there may be a relatively large number of optical cables to be coiled on the cable coiling part 3, if only one fiber guiding port is provided on the first disk surface 1 and the second disk surface 2, then all the optical cables can only be led out from this fiber guiding port and butt-jointed at a position near this fiber guiding port, which will cause the optical cables on the disk surface to be concentrated near this fiber guiding port, resulting in very messy optical cables on the disk surface. Therefore, in this embodiment, a plurality of fiber guiding ports are provided on both the first disk surface 1 and the second disk surface 2. The first preset number can be 2 to 4. The number of the first fiber guiding ports 11 on the first disk surface 1 is the same as the number of the second fiber guiding ports 21 on the second disk surface 2, and the distribution of the first fiber guiding ports 11 on the first disk surface 1 is the same as the distribution of the second fiber guiding ports 21 on the second disk surface 2. If too many fiber guiding ports are provided on the first disk surface 1 and the second disk surface 2, it may lead to too low structural strength of the first disk surface 1 and the second disk surface 2. Therefore, the number of fiber guiding ports that can be provided on the first disk surface 1 or the second disk surface 2 does not exceed 4.

[0081] In this embodiment, on the one hand, the optical cable coiling device is used for coiling multiple optical cables, and on the other hand, it is also necessary to ensure that all the optical cables coiled on the optical cable coiling device are in a butt-jointed state with each other. When the optical cables of the optical cable coiling device need to be used, the optical cables can be unloaded from the optical cable coiling device and directly used without butt-jointing each section of the optical cable at the application site, which can greatly improve the efficiency of the actual application of the optical cable. Therefore, in this embodiment, the head or tail end of each section of the optical cable on the cable coiling part 3 is led out through the first fiber guiding port 11 and the second fiber guiding port 21, and the heads and tails of different optical fibers are butt-jointed outside the first disk surface 1 or the second disk surface 2, so as to butt-joint all the optical cables on the cable coiling part 3 in sequence from beginning to end and connect them into an optical cable with a specified length.

[0082] For the convenience of understanding, the following example is used for demonstration: The a optical cable, the b optical cable, and the c optical cable are all coiled on the cable coiling part 3, and the three optical cables need to be connected in sequence according to the order of the a optical cable, the b optical cable, and the c optical cable. The a optical cable, the b optical cable, and the c optical cable are all coiled on the cable coiling part 3. The head end of the a optical cable is led out from the first fiber guiding port 11, and the tail end of the a optical cable is led out from the second fiber guiding port 21. The head end of the b optical cable is led out from the second fiber guiding port 21. The tail end of the a optical cable and the head end of the b optical cable are butt-jointed outside the second disk surface 2. The tail end of the b optical cable is led out from the first fiber guiding port 11. The head end of the c optical cable is led out from the first fiber guiding port 11. The tail end of the b optical cable and the head end of the c optical cable are butt-jointed outside the first disk surface 1. The tail end of the c optical cable is led out from the second fiber guiding port 21, and the connection of the a optical cable, the b optical cable, and the c optical cable is completed.

[0083] In this embodiment, to ensure that the butt-joint positions of all optical cables can be evenly distributed on the first disk surface 1 or the second disk surface 2, thus avoiding the messy arrangement of optical cables on the first disk surface 1 or the second disk surface 2, it is necessary to ensure that the lead-out positions of all optical cables on the first disk surface 1 or the second disk surface 2 are evenly distributed. Therefore, this embodiment involves the following design:

[0084] As Figure 7 and Figure 8 shown, the included angles between the connecting lines of the centers of every two adjacent first fiber leading ports 11 and the center of the first disk surface 1 are all equal; the included angles between the connecting lines of the centers of every two adjacent second fiber leading ports 21 and the center of the second disk surface 2 are all equal.

[0085] In this embodiment, all the first fiber leading ports 11 on the first disk surface 1 are evenly distributed around the center of the first disk surface 1, and the included angles between the connecting lines of every two adjacent first fiber leading ports 11 and the center of the first disk surface 1 are all the same. All the second fiber leading ports 21 on the second disk surface 2 are evenly distributed around the center of the second disk surface 2, and the included angles between the connecting lines of every two adjacent second fiber leading ports 21 and the center of the second disk surface 2 are all the same.

[0086] In this embodiment, when the optical cable is led out from the first fiber leading port 11 to the side surface of the first disk surface 1, or led out from the second fiber leading port 21 to the side surface of the second disk surface 2, the optical cable needs to be bent correspondingly at the first fiber leading port 11 or the second fiber leading port 21, and the bending path needs to pass through the notch edge of the first fiber leading port 11 or the second fiber leading port 21. To avoid damage to the optical cable caused by the sharp corners at the notch edges of the first fiber leading port 11 or the second fiber leading port 21, this embodiment involves the following design: As Figure 9 and Figure 10 shown, a first transition inclined surface 12 is provided on the side of the first fiber leading port 11 leading to the outside of the first disk surface 1, the first transition inclined surface 12 is arranged around the circumferential side of the first fiber leading port 11, the upper end of the first transition inclined surface 12 extends to the outer side surface of the first disk surface 1, and the lower end of the first transition inclined surface 12 extends to the first fiber leading port 11; a second transition inclined surface 22 is provided on the side of the second fiber leading port 21 leading to the outside of the second disk surface 2, the second transition inclined surface 22 is arranged around the circumferential side of the second fiber leading port 21, the upper end of the second transition inclined surface 22 extends to the outer side surface of the second disk surface 2, and the lower end of the second transition inclined surface 22 extends to the second fiber leading port 21.

[0087] In this embodiment, in the actual application scenario, when it is necessary to remove the optical cable from the optical cable reel, the common method is mostly to fix the axis of the optical cable reel and let the optical cable reel rotate around the axis position, and remove the optical cable in the fiber coiling direction while rotating. Therefore, in this embodiment, in order to facilitate the removal of the optical cable from the optical cable reel, the following design is also involved: AsFigure 10 As shown, the optical cable reel further includes a rotating hole 4, and the rotating hole 4 sequentially penetrates through the first disk surface 1, the fiber coiling part 3, and the second disk surface 2.

[0088] In this embodiment, the rotating hole 4 is located at the central positions of the first disk surface 1, the second disk surface 2, and the fiber coiling part 3. When it is necessary to remove the optical cable later, a rotating shaft is inserted into the rotating hole 4 to make the optical cable reel rotate around the rotating shaft, and at the same time, the optical cable is removed.

[0089] In this embodiment, in order to separate the optical cable inside the optical cable reel from the outside, the following design is also involved in this embodiment: As Figure 11 shown, the optical cable reel further includes a protective housing 5, wherein: the protective housing 5 is arranged around the circumferences of the first disk surface 1 and the second disk surface 2, one end of the protective housing 5 is connected to the circumferential side of the first disk surface 1, and the other end of the protective housing 5 is connected to the circumferential side of the second disk surface 2.

[0090] In this embodiment, since the optical cables stored in the optical cable reel need to be connected in sequence, and the connection positions of the optical cables are located outside the first disk surface 1 or the second disk surface 2, the following design is involved in the coupler 6 for the optical cables in this embodiment: As Figure 11 and Figure 12 shown, a second preset number of couplers 6 are detachably arranged on the first disk surface 1, and a third preset number of couplers 6 are detachably arranged on the second disk surface 2; the couplers 6 arranged on the first disk surface 1 are used to connect two optical cables led out from different first fiber guiding ports 11; the couplers 6 arranged on the second disk surface 2 are used to connect two optical cables led out from different second fiber guiding ports 21.

[0091] In this embodiment, both the second preset quantity and the third preset quantity are set by those skilled in the art according to the number of optical cables. That is, the number of optical cable butt joints on the first disk surface 1 is the second preset quantity, and the number of optical cable butt joints on the second disk surface 2 is the third preset quantity. In this embodiment, since the butt joint device 6 itself has a certain weight, the butt joint device 6 will pull on the optical cable due to its own gravity, which may cause damage to the optical cable and affect the stability of the butt joint part of the optical cable. Therefore, it is necessary to fix the butt joint device 6 on the first disk surface 1 or the second disk surface 2 to prevent the butt joint device 6 from pulling on the optical cable and damaging the optical cable. However, when the optical cable to be stored needs to be removed, the butt joint device 6 needs to be removed from the first disk surface 1 or the second disk surface 2 synchronously. Therefore, in this embodiment, the butt joint device 6 is detachably installed on the first disk surface 1 or the second disk surface 2, which is convenient for fixing the butt joint device 6 on the first disk surface 1 or the second disk surface 2 when transporting the optical cable reel, and at the same time is convenient for detaching the butt joint device 6 from the first disk surface 1 or the second disk surface 2 when the optical cable needs to be removed, that is, the detachable setting; in this embodiment, the detachable setting can be realized by the cooperation of screws and corresponding screw holes.

[0092] In this embodiment, in order to ensure the detachable setting of the butt joint device 6 relative to the first disk surface 1 and the second disk surface 2, a preferred setting is provided as follows: As Figure 13 and Figure 14 shown, a plurality of screw hole platforms 63 are further provided on the outer side of the outer shell box body 61, and a first screw hole 631 is provided on each screw hole platform 63. Second screw holes 8 are provided at corresponding positions on the first disk surface 1 and the second disk surface 2. The second screw holes 8 are used to correspond to the positions of the first screw holes 631, and the butt joint device 6 is fixed on the first disk surface 1 or the second disk surface 2 by screws.

[0093] In this embodiment, the butt joint device 6 needs to be arranged on the periphery of the through hole 4 of the first disk surface 1 and the second disk surface 2. Therefore, the second screw holes 8 corresponding to the first screw holes 631 are located on the periphery of the through hole 4 of the first disk surface 1 and the second disk surface 2; in this embodiment, the outer shell box body 61 is in the shape of a cuboid, and four screw hole platforms 63 are provided on the four side surfaces of the outer shell box body 61. Corresponding to this, every four second screw holes 8 on the first disk surface 1 and the second disk surface 2 are in a group, which are used to cooperate with the first screw holes 631 on the screw hole platforms 63 of the corresponding outer shell box body 61 through screws. Each group of second screw holes 8 is arranged on the periphery of the through hole 4 and is located between two adjacent first fiber guiding ports 11 or two adjacent second fiber guiding ports 21.

[0094] A cover plate is further provided on the outer shell box body 61 for separating the inside of the outer shell box body 61 from the outside world.

[0095] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
