Description

Technical Field

[0001] This invention relates to the field of optical fiber connection technology, and more particularly to a flip-type physical connector. Background Technology

[0002] Currently, conventional field fiber optic connectors require manual alignment of the fiber optic cable before it can be inserted into the fiber optic splice assembly. Because the V-groove inlet hole is very small, it becomes very difficult to insert the fiber optic cable into the V-groove when the ambient light is dim or the operator's vision is poor. It is difficult to insert the fiber optic cable into the splice assembly intact, and the fiber optic cable may come into contact with the components, which can easily damage the fiber optic end face, causing field assembly failure or connection failure.

[0003] A flip-type fusible physical connector with prior art disclosure number CN213715533U includes a main body, a V-groove assembly, and a flip cover. The front of the main body forms the end of the positioning V-groove assembly, and the rear is provided with a cable clamping push block that matches it. The V-groove assembly includes an external control switch for optical fiber and a pre-embedded optical fiber. When the cable clamping push block is pushed inward to the limit position, the optical fiber placed on the cable clamping push block is connected to the pre-embedded optical fiber. Rotating shafts are provided on both sides of the main body, and the rotating shafts are connected to the flip cover. A sealing flip cover for sealing cables is provided on the upper rear end of the cable clamping push block. One side of the sealing flip cover is connected to the main body of the cable clamping push block by a plastic sheet.

[0004] While existing technologies can achieve fusion-free physical splicing of optical fibers, allowing the fiber ends to abut against each other, their constraint and positioning effects on the fiber splicing position are limited in practical use. This makes it difficult to guarantee coaxial accuracy when the two fibers abut, and problems such as eccentricity and offset can easily occur, thus affecting the stability and transmission performance of the fiber splicing. To address these shortcomings of poor coaxiality and insufficient splicing accuracy, this application proposes a flip-type physical connector with a more optimized structure and more reliable positioning. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems by proposing a flip-type physical connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flip-type physical connector includes a male connector and a female connector. The male connector has a connection groove and a top cover is hinged to the upper end of the male connector. A first connecting optical fiber is provided inside the connection groove, and a second connecting optical fiber is provided on the female connector. The connector also includes a connection mechanism for coaxial connection of the first connecting optical fiber and the second connecting optical fiber. The connecting mechanism includes a connecting block that mates with a connecting groove. A rotating cylinder is mounted on the connecting block, and an air supply unit is located at the end of the rotating cylinder. Two piston cylinders connected to the air supply unit are located inside the rotating cylinder. A movable piston is slidably connected inside the piston cylinder. A spring is fixed to the movable piston and the piston cylinder, and a drive rod is fixed to the movable piston. An arc-shaped block is fixed to the drive rod, abutting against the first and second connecting optical fibers. When the male and female connectors are connected, the rotating cylinder rotates, and the air supply unit supplies air into the piston cylinder, driving the movable piston, drive rod, and arc-shaped block to move. The arc-shaped block abuts against and rotates against the first and second connecting optical fibers.

[0007] Preferably, when the male connector and the female connector are connected, the male connector and the female connector are connected by two locking mechanisms. The locking mechanism includes a wedge-shaped locking block fixed on the male connector and an L-shaped locking hook on the female connector. The L-shaped locking hook is engaged with the wedge-shaped locking block.

[0008] Preferably, the connecting block is provided with an annular groove, the annular groove is provided with a spiral groove, a rotating ring is slidably connected in the annular groove, a ball is installed on the rotating ring, the ball is slidably connected in the spiral groove, and the rotating cylinder is fixed on the rotating ring.

[0009] Preferably, the inner wall of the connecting groove is connected to a rotating ring via a bearing. The rotating ring is coaxially arranged with the first connecting optical fiber and is arranged opposite to the air supply unit.

[0010] Preferably, the air supply unit includes an annular mounting cover corresponding to the rotating ring, the annular mounting cover is provided with an annular mounting groove, an annular airbag is fixed in the annular mounting groove, a compression ring is slidably connected in the annular mounting groove, the compression ring is fixedly connected to the rotating cylinder, and the annular airbag is connected to the piston cylinder through a delivery pipe.

[0011] Preferably, a limiting mechanism is provided between the extrusion ring and the annular mounting cover. The limiting mechanism includes multiple limiting blocks fixed on the outer wall of the extrusion ring, and a limiting groove is provided on the inner wall of the annular mounting groove. The limiting groove is arranged along the axial direction of the annular mounting cover, and the limiting blocks are slidably connected in the limiting groove.

[0012] Preferably, a limiting ring is fixed on the annular mounting cover, and the inner diameter of the limiting ring is smaller than the outer diameter of the extrusion ring.

[0013] Preferably, the inner wall of the rotating cylinder is fixed with a mounting base, and the piston cylinder is fixed to the mounting base by bolts.

[0014] Preferably, a friction pad is fixed on the side of the annular mounting cover opposite to the limiting block. The friction pad is made of rubber and is coaxially arranged with the rotating ring.

[0015] Preferably, a sealing ring is fixed on the female connector, and the sealing ring is in a compressed state when the male connector abuts against the female connector.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. This connector eliminates the need for manual alignment of the optical fiber. When the male and female connectors are mated, the connecting block is inserted into the connecting slot to achieve initial positioning. The arc-shaped block automatically clamps the optical fiber, solving the problem of difficulty in inserting the optical fiber in traditional connectors due to the small V-groove inlet hole, low light, or poor vision. It avoids end-face damage caused by the optical fiber touching the components, significantly reducing the failure rate of on-site assembly and the probability of connection failure, and improving the ease of operation for on-site optical fiber splicing.

[0017] 2. By using air pressure to drive symmetrically arranged arc-shaped blocks to radially clamp the optical fiber, combined with rotational centering action, it can automatically eliminate eccentricity and offset errors during optical fiber docking, enabling the two connecting optical fibers to achieve high-precision and fully coaxial docking. Compared with existing technologies, this significantly improves the coaxial accuracy of optical fiber docking, effectively avoids transmission problems caused by insufficient docking position constraints, and ensures the transmission stability and low loss of optical fiber communication.

[0018] 3. The components of the connection mechanism work together to complete the fiber optic connection through a series of actions including docking guidance, snap-locking, pneumatic drive, radial clamping, and rotational alignment. The overall structure is compact and optimized, and the symmetrical arrangement of components such as the piston cylinder and arc block ensures uniform clamping force.

[0019] In summary, this invention eliminates the need for manual alignment of optical fibers, effectively avoiding damage to the fiber end face and reducing the assembly failure rate. By using pneumatically driven arc-shaped blocks for clamping and rotational alignment, it automatically eliminates eccentricity and offset, achieving high-precision coaxial connection of optical fibers and ensuring stable and low-loss transmission.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Reference Figures 1-8 A flip-type physical connector includes a male connector 1 and a female connector 2. The two parts are quickly locked and positioned via a snap-fit ​​mechanism, and a high-precision coaxial connection between the first connecting optical fiber 7 and the second connecting optical fiber 10 is achieved through an internal connection mechanism. The overall structure adopts a symmetrical design. Both the male connector 1 and the female connector 2 are injection molded from engineering plastics, possessing good insulation, structural strength, and environmental resistance, making them suitable for rapid field splicing and fixed connection scenarios in the field of fiber optic communication.

[0024] The male connector 1 is rectangular in shape, with a connecting groove 29 at the front end for mating with the female connector 2. The connecting groove 29 is a rectangular recessed groove, and its depth matches the length of the connecting block 8 inserted at the front end of the female connector 2. The first connecting optical fiber 7 is fixedly installed inside the male connector 1 along its axis. The end of the first connecting optical fiber 7 extends to the center of the connecting groove 29, and its end face is precision ground to ensure optical transmission performance during mating.

[0025] The upper end of the male connector 1 is hinged to a top cover 5, which is positioned opposite to the connecting groove 29. A sealing gasket is provided between the top cover 5 and the male connector 1 to ensure a tight seal when the top cover 5 is on. During installation, the top cover 5 is in the open position to check the end face of the first connecting optical fiber 7 and its installation inside the male connector 1. After the top cover 5 is on, the connecting block 8 can be further limited to ensure the stability of the connecting block 8 sliding within the connecting groove 29, thereby ensuring the accuracy of the connection between the first connecting optical fiber 7 and the second connecting optical fiber 10.

[0026] The locking mechanism is used to quickly lock and axially fix the male connector 1 and the female connector 2. It includes two sets of symmetrically arranged wedge-shaped locking blocks 3 and L-shaped locking hooks 4. The wedge-shaped locking blocks 3 are integrally formed on the outer wall of the male connector 1. The cross-section is a right trapezoid. The guide slope facilitates the smooth sliding of the L-shaped locking hooks 4. The vertical locking surface cooperates with the hook part of the L-shaped locking hooks 4 to form axial locking.

[0027] The female connector 2 is also rectangular in shape, with an insertion section at the front end that fits into the connecting groove 29. This insertion section is the connecting block 8. Inside, a second connecting optical fiber 10 is fixedly installed along the axis. The end of the second connecting optical fiber 10 extends to the end face of the insertion section and is positioned opposite to the first connecting optical fiber 7. The end face is also precision ground. Two sets of L-shaped locking hooks 4 are symmetrically arranged on the outer wall of the female connector 2 at the position corresponding to the wedge-shaped locking block 3. The L-shaped locking hooks 4 are made of elastic plastic. One end is integrally connected to the shell of the female connector 2, and the other end is a hook-shaped structure that can be elastically deformed. The hook part fits into the vertical locking surface of the wedge-shaped locking block 3 to achieve axial locking after the male connector 1 and the female connector 2 are connected, preventing accidental loosening during use.

[0028] A sealing ring is provided between the mating end faces of male connector 1 and female connector 2. The sealing ring is made of rubber and is fixed in the annular sealing groove on the front end face of female connector 2. When male connector 1 and female connector 2 are fully engaged, the sealing ring is squeezed and undergoes elastic deformation to form a reliable radial and axial seal, preventing external dust and moisture from entering the mating area and improving the long-term stability of the connector in complex environments such as outdoor and computer rooms.

[0029] The connection mechanism is the core component for achieving high-precision coaxial docking between the first connecting optical fiber 7 and the second connecting optical fiber 10. It includes a connecting block 8, a rotating cylinder 11, an air supply unit, a piston cylinder 13, a moving piston 27, a drive rod 25, and an arc-shaped block 12. All components work together to complete the centering, clamping, and rotational alignment of the optical fiber.

[0030] The connecting block 8 is fixedly installed at the center of the female connector 2, coaxially with the second connecting optical fiber 10. The outer wall of the connecting block 8 is clearance-fitted with the inner wall of the connecting groove 29. When the male connector 1 and the female connector 2 are mated, the connecting block 8 is inserted into the connecting groove 29 for initial positioning. An annular groove 14 is formed on the outer wall of the connecting block 8, extending circumferentially. The inner wall of the annular groove 14 is machined with a spiral groove 15, which is a continuous spiral guide groove. The spiral helix angle is set according to the rotational alignment requirements to ensure that the rotating cylinder 11 can rotate smoothly during the mating of the male and female connectors. A rotating ring 16 is slidably installed in the annular groove 14. The outer wall of the rotating ring 16 is provided with ball bearings 17, which are slidably connected in the spiral groove 15. The ball bearings 17 and the spiral groove 15 are clearance-fitted to ensure smooth sliding without jamming. When the connecting block 8 is inserted into the connecting groove 29 along with the female connector 2, the ball bearings 17 slide along the spiral groove 15, driving the rotating ring 16 to rotate around the axis, thereby driving the rotating cylinder 11 to rotate synchronously.

[0031] Among them, a rotatable and coaxial connecting ring can be fixed on the rotating ring 16, and a return spring is fixed on the connecting ring. The other end of the return spring is fixed to the inner side wall of the annular groove 14. The return spring is used to reset the rotating ring 16 and the rotating cylinder 11.

[0032] The rotating cylinder 11 is fixedly installed on the side of the rotating ring 16 facing the male connector 1, and is coaxially arranged with the rotating ring 16. The rotating cylinder 11 is a cylindrical body with a hollow interior for installing the piston cylinder 13 and related transmission components. Two sets of mounting seats 24 are symmetrically fixed to the inner wall of the rotating cylinder 11. The mounting seats 24 fix the piston cylinder 13 to the piston cylinder 13 by bolts. The piston cylinder 13 is arranged radially along the rotating cylinder 11, and the two sets of piston cylinders 13 are symmetrically distributed at 180° to ensure uniform radial clamping force. A movable piston 27 is slidably connected inside the piston cylinder 13. The outer wall of the movable piston 27 is tightly fitted with the inner wall of the piston cylinder 13 and sealed with a sealing ring to prevent gas leakage. A spring 28 is fixed between the movable piston 27 and the closed end of the piston cylinder 13. In the natural state, pulling the movable piston 27 towards the closed end of the piston cylinder 13 causes the arc-shaped block 12 to be in a relaxed state, which facilitates the insertion of optical fiber.

[0033] A drive rod 25 is fixed to one end of the movable piston 27 away from the spring 28. The drive rod 25 extends to the outside of the piston cylinder 13, and an arc-shaped block 12 is fixed to its end. The inner wall of the arc-shaped block 12 is an arc surface that matches the outer diameter of the optical fiber, and the surface is polished to avoid scratching the cladding of the optical fiber during clamping. Two sets of arc-shaped blocks 12 are arranged opposite each other. When closed, they form a circular clamping hole, which wraps and centers the mating section of the first connecting optical fiber 7 and the second connecting optical fiber 10 to ensure their coaxiality. When the two arc-shaped blocks 12 abut against each other, the arc-shaped blocks 12 are completely in contact with the first connecting optical fiber 7 and the second connecting optical fiber 10, thus further ensuring the coaxiality of the first connecting optical fiber 7 and the second connecting optical fiber 10.

[0034] To prevent the first connecting optical fiber 7 and the second connecting optical fiber 10 from shifting to one side due to the different pressure of the arc block 12, a retaining ring can be fixed inside the piston cylinder 13. When the arc block 12 is fully attached to the first connecting optical fiber 7 and the second connecting optical fiber 10, the moving piston 27 abuts against the retaining ring. This avoids the possibility of a slight difference in resistance between the two pistons due to manufacturing process or long-term use, which could cause the two arc blocks to move asynchronously, resulting in a difference in the thrust on the optical fiber and exacerbating the eccentricity problem.

[0035] The gas supply unit provides pneumatic driving force to the piston cylinder 13 and includes an annular mounting cover 9, an annular air bladder 23, a compression ring 21, and a delivery pipe 26. The annular mounting cover 9 is fixed to the end of the rotating cylinder 11 facing the male connector 1 and is coaxially arranged with the rotating cylinder 11. A through hole for the optical fiber to pass through is opened in the center of the annular mounting cover 9. An annular mounting groove 18 is opened on the side of the annular mounting cover 9 facing the male connector 1. The annular air bladder 23 is fixedly installed inside the annular mounting groove 18. The annular air bladder 23 is made of elastic rubber and filled with inert gas, maintaining an inflated state under normal conditions. The compression ring 21 is slidably connected inside the annular mounting groove 18. The compression ring 21 is fixedly connected to the rotating cylinder 11 and rotates synchronously with the rotating cylinder 11. The end face of the compression ring 21 is in contact with the annular air bladder 23. When the rotating cylinder 11 moves axially, it drives the compression ring 21 to compress the annular air bladder 23, causing the volume of the annular air bladder 23 to contract and the internal gas pressure to increase.

[0036] The annular airbag 23 is connected to the inside of the piston cylinder 13 via a delivery pipe 26. The delivery pipe 26 is a flexible air pipe, arranged along the inner wall of the rotating cylinder 11, with its two ends sealed to the air outlet of the annular airbag 23 and the air inlet of the piston cylinder 13, respectively, to ensure stable air pressure transmission. A limiting mechanism is provided between the extrusion ring 21 and the annular mounting cover 9. The limiting mechanism includes multiple limiting blocks 22 and limiting grooves 19. The limiting blocks 22 are uniformly fixed to the outer wall of the extrusion ring 21, and the limiting grooves 19 are axially opened along the inner wall of the annular mounting groove 18 of the annular mounting cover 9. The limiting blocks 22 are slidably connected in the limiting grooves 19 to restrict the circumferential rotation of the extrusion ring 21, while ensuring that the extrusion ring 21 can only move axially, avoiding displacement during the extrusion process and ensuring uniform force on the annular airbag 23. A limiting ring 20 is fixed to the end of the annular mounting cover 9. The inner diameter of the limiting ring 20 is smaller than the outer diameter of the extrusion ring 21 to prevent the extrusion ring 21 from falling out of the annular mounting groove 18 and to ensure structural stability.

[0037] The inner wall of the connecting groove 29 of the male connector 1 is rotatably connected to the rotating ring 6 via a bearing. The rotating ring 6 is coaxially arranged with the first connecting optical fiber 7, and its end face is opposite to the friction pad on the annular mounting cover 9. The friction pad is fixed on the side of the annular mounting cover 9 away from the rotating cylinder 11. It is made of rubber with a rough surface. When the male connector 1 and the female connector 2 are mated, the friction pad is in close contact with the end face of the rotating ring 6. The friction helps the rotating cylinder 11 to rotate stably, and at the same time, it plays a buffering role to avoid rigid collision damage to the optical fiber.

[0038] During connection, cover the top cover 5, then insert the female connector 2 into the connecting groove 29 of the male connector 1. The front end of the L-shaped locking hook 4 contacts the guide slope of the wedge-shaped locking block 3 and elastically opens outward under the action of thrust. When the male connector 1 and the female connector 2 are fully engaged, the L-shaped locking hook 4 retracts under its own elasticity, and the hook part engages with the locking surface of the wedge-shaped locking block 3, completing the automatic engagement without the need for additional tools. During disassembly, manually pry the L-shaped locking hook 4 outward to disengage the hook part from the wedge-shaped locking block 3, thus separating the male and female connectors. The operation is convenient and suitable for quick on-site assembly and disassembly scenarios.

[0039] This connector achieves high-precision coaxial splicing of optical fibers through five steps: docking guidance, snap-locking, pneumatic drive, radial clamping, and rotational alignment. The specific process is as follows: In use, the front end of the female connector 2 is inserted into the connecting groove 29 of the male connector 1, and the connecting block 8 is simultaneously inserted into the connecting groove 29 to achieve the initial radial positioning of the male and female connectors. The ends of the first connecting optical fiber 7 and the second connecting optical fiber 10 enter the interior of the rotating cylinder 11 and are located between the two sets of arc-shaped blocks 12.

[0040] As the male and female connectors are continuously pushed closer together, the L-shaped locking hook 4 contacts the guide slope of the wedge-shaped locking block 3 and elastically opens outward. When the end faces of the male and female connectors are fully fitted, the L-shaped locking hook 4 rebounds and the hook part is inserted into the locking surface of the wedge-shaped locking block 3 to complete axial locking. At this time, the sealing ring is squeezed to achieve sealing protection.

[0041] During the mating process of the male and female connectors, the friction pad on the annular mounting cover 9 contacts the rotating ring 6 inside the male connector 1. As the connecting block 8 continues to be inserted axially, the ball bearings 17 on the rotating ring 16 slide along the spiral groove 15 on the connecting block 8, converting the axial feed motion into rotational motion, driving the rotating ring 16 and the rotating cylinder 11 to rotate synchronously around the axis. At the same time, the rotating cylinder 11, with the axial feed of the connecting block 8, drives the compression ring 21 to move axially relative to the annular mounting cover 9, compressing the annular air bladder 23. The annular air bladder 23 is compressed and the high-pressure gas inside is transported to the inside of the two sets of piston cylinders 13 through the delivery pipe 26.

[0042] After the gas in the annular airbag 23 enters the piston cylinder 13, it pushes the moving piston 27 to move radially against the elastic force of the spring 28. The moving piston 27 drives the arc block 12 to move towards the optical fiber through the drive rod 25. The two sets of symmetrical arc blocks 12 close synchronously, tightly clamping the docking section of the first connecting optical fiber 7 and the second connecting optical fiber 10. The symmetrical clamping force achieves initial centering, ensuring that the optical fiber is in the center position of the rotating cylinder 11.

[0043] After the arc-shaped block 12 abuts against the optical fiber, it continues to rotate at a low speed with the rotating cylinder 11, driving the two piston cylinders 13 to rotate synchronously, which in turn drives the moving piston 27 and the drive rod 25 to rotate, thereby driving the arc-shaped block 12 to rotate. During the rotation, relying on the abutment between the arc-shaped block 12 and the first connecting optical fiber 7 and the second connecting optical fiber 10, as well as the rotation correction effect, the eccentricity and offset errors during optical fiber docking are automatically eliminated, so that the first connecting optical fiber 7 and the second connecting optical fiber 10 reach a completely coaxial state with their end faces tightly abutting, ensuring the stability and low loss of optical transmission.

[0044] After docking, the air pressure inside the piston cylinder 13 remains stable, the arc-shaped block 12 continues to clamp the optical fiber, and the spring 28 is in a stretched state, providing auxiliary rebound force to prevent insufficient clamping force due to air pressure fluctuations. During disassembly, the L-shaped locking hook 4 is pried open to release the lock, the male and female connectors are separated, the compression ring 21 loses axial pressure, the annular airbag 23 resumes expansion, the air pressure inside the piston cylinder 13 decreases, and the moving piston 27 retracts under the elastic force of the spring 28, causing the arc-shaped block 12 to release the optical fiber, thus completing the disassembly.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
