Description

Technical Field

[0001] This utility model belongs to the field of optical fiber communication technology, specifically relating to an anti-misoperation electric lock for an optical fiber FC-FC coupler. Background Technology

[0002] Fiber optic communication, as a crucial component of modern communication technology, is widely used in data centers, communication networks, and industrial control. Fiber optic FC-FC couplers are key components in fiber optic communication systems, used to connect fiber optic devices. However, existing fiber optic FC-FC couplers lack effective mechanisms to prevent accidental disconnection; operators may accidentally disconnect the coupler due to negligence or misoperation, affecting communication stability. Furthermore, due to the limited internal space of fiber optic junction boxes, traditional physical locks cannot meet the demands for high security and intelligent management. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a fiber optic FC-FC coupler anti-misoperation electric control lock that is simple in structure, easy to operate, and highly reliable.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an anti-misoperation electric lock for an optical fiber FC-FC coupler, wherein the optical fiber FC-FC coupler is installed on the side plate of the optical fiber hub box, half of the optical fiber FC-FC coupler is located inside the optical fiber hub box, and the other half of the optical fiber FC-FC coupler is located outside the optical fiber hub box. The feature is that it includes a one-way anti-rotation ratchet tooth, a limiting lock tongue, and a lock tongue control device; the lock tongue control device is located inside the optical fiber hub box, the one-way anti-rotation ratchet tooth is coaxially arranged on the outer circle of the internal thread sleeve of the optical fiber FC-FC coupler outside the optical fiber hub box, one end of the limiting lock tongue is located inside the optical fiber hub box and connected to the mechanical power output end of the lock tongue control device, and the other end of the limiting lock tongue extends out of the side plate of the optical fiber hub box and engages with the one-way anti-rotation ratchet tooth.

[0005] The locking tongue control device includes a mounting base and a motor base. The mounting base is fixedly installed at the bottom of the fiber optic junction box. The motor base has a micro motor with its main shaft parallel to the center line of the fiber optic FC-FC coupler. The motor base is fixedly connected to the mounting base by a first bolt. The mounting base has a vertical guide hole with a lifting column inside. A first tension spring is provided between the lower end of the lifting column and the bottom of the guide hole. A drive groove is opened on the side of the lifting column facing the micro motor. An eccentric shaft extending into the drive groove is fixedly installed on the outer end face of the main shaft of the micro motor. A connecting plate is rotatably connected to the mounting base by a pin perpendicular to the center line of the fiber optic FC-FC coupler. The upper end of the lifting column contacts the bottom surface of the connecting plate. A second tension spring is vertically installed inside the mounting base. The upper end of the second tension spring is connected to the bottom surface of the connecting plate, and the lower end of the second tension spring is connected to the bottom of the mounting base. The limiting locking tongue is located directly above the fiber optic FC-FC coupler. The length direction of the limiting locking tongue is parallel to the center line of the fiber optic FC-FC coupler, and the inner end of the limiting locking tongue is fixedly connected to the connecting plate.

[0006] The one-way anti-rotation ratchet tooth and the internal threaded sleeve are manufactured as a single piece. One one-way anti-rotation ratchet tooth is set on the outer circle of the internal threaded sleeve. The outer diameter of three-quarters of the outer circle of the one-way anti-rotation ratchet tooth is equal, while the outer diameter of the other quarter of the outer circle of the one-way anti-rotation ratchet tooth gradually increases.

[0007] The mounting base has a groove in the middle for accommodating and placing a micro motor.

[0008] The connecting plate extends downwards on both sides of the mounting base and is rotatably connected to the two ends of the pin. The connecting plate and the limit lock tongue are manufactured as a single piece.

[0009] Using the above technical solution, during normal operation of the fiber optic junction box, the limiting lock tongue prevents the one-way anti-rotation ratchet teeth from rotating in the loosening direction, allowing only tightening, thus preventing the internal threaded sleeve from loosening and causing accidental interruption of optical communication. When maintenance requires opening the fiber optic FC-FC coupler, use the NFC function of your mobile phone and bring the phone close to the NFC antenna located on the outside of the fiber optic junction box (distance ≤ 5cm). The NFC antenna transmits the signal to the NFC control module located inside the fiber optic junction box. The NFC control module automatically recognizes and authorizes the micro motor to start. The main shaft of the micro motor drives the eccentric shaft to rotate at a certain angle. During the rotation, the eccentric shaft drives the lifting column to move upward in the guide hole. The lifting column lifts the connecting plate upward, and the limiting lock tongue, which is integrated with the connecting plate, rotates upward around the pin axis. The limiting lock tongue rises upward, and the bottom surface of the limiting lock tongue is higher than the maximum diameter of the one-way anti-rotation ratchet teeth. The limiting lock tongue no longer obstructs the one-way anti-rotation ratchet. Loosen the internal threaded sleeve (rotate counterclockwise) to disassemble the fiber optic FC-FC coupler. After a period of time, the main shaft of the micro motor rotates in the reverse direction to reset, the eccentric shaft drives the lifting column to move downward, the second spring pulls the connecting plate downward to reset, and the limit lock tongue follows the connecting plate downward to reset. When the maintenance is completed, when the internal threaded sleeve and the one-way anti-rotation ratchet are tightened clockwise, the limit lock tongue will not block the rotation of the one-way anti-rotation ratchet because the outer circle of the one-way anti-rotation ratchet is in sliding contact with the limit lock tongue, until the internal threaded sleeve is tightened. When the internal threaded sleeve and the one-way anti-rotation ratchet rotate counterclockwise, the one-way anti-rotation ratchet is blocked by the limit lock tongue and cannot rotate, thus preventing accidental disconnection of the fiber optic FC-FC coupler.

[0010] A groove is provided in the middle of the mounting base to accommodate the micro motor, making the entire structure more compact.

[0011] The connecting plate and the limit lock tongue are machined as a single unit, which gives the limit lock tongue good elasticity and toughness, thus ensuring the reliability of the entire limit one-way anti-rotation ratchet.

[0012] In summary, this invention is based on sound principles and aims to solve the problem of accidental disconnection of fiber optic FC-FC couplers during operation. It employs a micro-motor that drives the connecting plate to rise via an eccentric shaft. Simultaneously, the connecting plate drives the limit locking tongue to rise, achieving the unlocking function. After locking, the limit locking tongue prevents the one-way anti-rotation ratchet from loosening, effectively preventing accidental disconnection of the fiber optic FC-FC coupler. This invention has a simple and compact structure, high reliability, fills a market gap, and has significant practical application value. It can be widely used in communications, data centers, and other fields, effectively improving the security and management efficiency of fiber optic equipment, and has important practical significance.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0019] like Figures 1-5 As shown, the fiber optic FC-FC coupler anti-misoperation electric lock of this utility model has a fiber optic FC-FC coupler 9 installed on the side plate of the fiber optic junction box 5. Half of the fiber optic FC-FC coupler 9 is located inside the fiber optic junction box 5, and the other half is located outside the fiber optic junction box 5. It includes a one-way anti-rotation ratchet tooth 3, a limiting lock tongue 4, and a lock tongue control device 21. The lock tongue control device 21 is located inside the fiber optic junction box 5. The one-way anti-rotation ratchet tooth 3 is coaxially arranged on the outer circle of the internal thread sleeve 6 of the fiber optic FC-FC coupler 9 outside the fiber optic junction box 5. One end of the limiting lock tongue 4 is located inside the fiber optic junction box 5 and is connected to the mechanical power output end of the lock tongue control device 21. The other end of the limiting lock tongue 4 extends out of the side plate of the fiber optic junction box 5 and is engaged with the one-way anti-rotation ratchet tooth 3.

[0020] The latch control device 21 includes a mounting base 7 and a motor base 8. The mounting base 7 is fixedly installed at the bottom of the fiber optic junction box 5. The motor base 8 is equipped with a micro motor 10 whose main shaft is parallel to the center line of the fiber optic FC-FC coupler 9. The motor base 8 is fixedly connected to the mounting base 7 by a first bolt 11. The mounting base 7 has a vertical guide hole, and a lifting column 12 is installed in the guide hole. A first tension spring 13 is provided between the lower end of the lifting column 12 and the bottom of the guide hole. A drive groove 14 is opened on the side of the lifting column 12 facing the micro motor 10. The outer end face of the main shaft of the micro motor 10 is fixedly provided with a part that extends into the drive groove 14. An eccentric shaft 15 is mounted on the mounting base 7. A connecting plate 17 is rotatably connected to the mounting base 7 via a pin 16 perpendicular to the center line of the fiber FC-FC coupler 9. The upper end of the lifting column 12 contacts the bottom surface of the connecting plate 17. A second tension spring 18 is vertically installed inside the mounting base 7. The upper end of the second tension spring 18 is connected to the bottom surface of the connecting plate 17, and the lower end of the second tension spring 18 is connected to the bottom of the mounting base 7. The limiting lock tongue 4 is located directly above the fiber FC-FC coupler 9. The length direction of the limiting lock tongue 4 is parallel to the center line of the fiber FC-FC coupler 9, and the inner end of the limiting lock tongue 4 is fixedly connected to the connecting plate 17.

[0021] The one-way anti-rotation ratchet tooth 3 and the internal threaded sleeve 6 are manufactured as a single piece. One one-way anti-rotation ratchet tooth 3 is set on the outer circle of the internal threaded sleeve 6. The outer diameter of three-quarters of the outer circle of the one-way anti-rotation ratchet tooth 3 is equal, and the outer diameter of the other quarter of the outer circle of the one-way anti-rotation ratchet tooth 3 gradually increases.

[0022] The outer side of the fiber optic hub box 5 is provided with a placement slot 19 for placing the NFC antenna 1, and a decorative cover that can be snapped open is provided at the second tension spring 18.

[0023] The mounting base 7 has a groove 20 in the middle for accommodating and placing the micro motor 10.

[0024] The connecting plate 17 extends downward on the left and right sides of the mounting base 7 and is rotatably connected to the two ends of the pin 16. The connecting plate 17 and the limiting lock tongue 4 are integrally manufactured.

[0025] During normal operation of the fiber optic junction box 5, the limit locking tongue 4 blocks the rotation of the one-way anti-rotation ratchet tooth 3 in the loosening direction, and can only tighten it, thereby preventing the internal threaded sleeve 6 from loosening and causing the optical communication to be interrupted. When the fiber optic FC-FC coupler 9 needs to be opened for maintenance, use the NFC function of your mobile phone and bring the phone close to the NFC antenna 1 located on the outside of the fiber optic hub box 5 (distance ≤ 5cm). The NFC antenna 1 transmits the signal to the NFC control module 2 located inside the fiber optic hub box 5. The NFC control module 2 automatically recognizes and authorizes the micro motor 10 to start. The main shaft of the micro motor 10 drives the eccentric shaft 15 to rotate at a certain angle. During the rotation, the eccentric shaft 15 drives the lifting column 12 to move upward in the guide hole. The lifting column 12 pushes the connecting plate 17 upward. The limiting lock tongue 4, which is integrated with the connecting plate 17, rotates upward around the pin shaft 16 as the center line. The limiting lock tongue 4 is raised upward, and the bottom surface of the limiting lock tongue 4 is higher than the maximum diameter of the one-way anti-rotation ratchet tooth 3. The limiting lock tongue 4 no longer blocks the one-way anti-rotation ratchet. Loosen the internal thread sleeve 6 (rotate counterclockwise) to disassemble the fiber optic FC-FC coupler 9. After a period of time, the main shaft of the micro motor 10 rotates in the reverse direction to reset, the eccentric shaft 15 drives the lifting column 12 to move downward, the second spring pulls the connecting plate 17 downward to reset, and the limit lock tongue 4 follows the connecting plate 17 downward to reset. When the maintenance is completed, when the internal threaded sleeve 6 and the one-way anti-rotation ratchet are tightened clockwise, the limit lock tongue 4 will not block the rotation of the one-way anti-rotation ratchet because the outer circle of the one-way anti-rotation ratchet is in sliding contact with the limit lock tongue 4, until the internal threaded sleeve 6 is tightened. When the internal threaded sleeve 6 and the one-way anti-rotation ratchet rotate counterclockwise, the one-way anti-rotation ratchet is blocked by the limit lock tongue 4 and cannot rotate, thus preventing accidental disconnection of the fiber optic FC-FC coupler 9.

[0026] The second tension spring 18 is provided to house the NFC antenna 1 and is equipped with a decorative cover to protect the NFC antenna 1 from damage.

[0027] The mounting base 7 has a groove 20 in the middle for placing the micro motor 10, making the whole structure more compact.

[0028] The connecting plate 17 and the limiting lock tongue 4 are integrally machined, which gives the limiting lock tongue 4 good elasticity and toughness, thereby ensuring the reliability of the entire limiting one-way anti-rotation ratchet.

[0029] It should be emphasized that the NFC antenna 1, NFC control module 2 and micro motor 10 in this utility model are all existing technologies and can be purchased on the market. The automatic control and signal transmission do not involve new computer programs.
