Technical Field

[0001] The present invention belongs to the technical field of optical fibers, and particularly relates to a portable optical fiber connector. Background Art

[0002] An optical fiber is the abbreviation of an optical waveguide fiber, which is a fiber made of glass or plastic and can be used as a tool for optical conduction. When connecting between optical fibers, an optical fiber connecting component is required. It precisely connects the two end faces of the optical fibers so that the optical energy output by the transmitting optical fiber can be coupled into the receiving optical fiber to the greatest extent, and the impact on the system caused by its insertion into the optical link is minimized.

[0003] The existing optical fiber connecting components may cause the loosening or even disintegration of the connecting components under long-term use and external factors, unable to ensure the stability of the connection between optical fibers, affecting the transmission of optical fiber signals, and causing the optical fibers to malfunction. Summary of the Invention

[0004] The present invention provides a portable optical fiber connector, aiming to solve the problem that the existing optical fiber connecting components may cause the loosening or even disintegration of the connecting components under long-term use and external factors, unable to ensure the stability of the connection between optical fibers, affecting the transmission of optical fiber signals, and causing the optical fibers to malfunction.

[0005] An embodiment of the present invention provides a portable optical fiber connector, including optical fiber A and optical fiber B. Optical fiber A and optical fiber B are connected to each other via a connecting component. A protective member is movably installed on optical fiber A and optical fiber B, and the connecting component is located inside the protective member;

[0006] The connecting component includes connecting part A and connecting part B. Connecting part B includes joint B fixedly connected to optical fiber A, protective sleeve B and connecting part tube installed inside joint B. Connecting part A includes joint A threadedly connected to joint B, protective sleeve A screwed inside joint A, and optical fiber core installed inside protective sleeve A;

[0007] A leak-proof part and ring B are fixedly connected inside the connection of joint B, and a variable column for expanding the leak-proof part is movably installed at the connection of joint B;

[0008] Inside the connection of joint A, ring A is movably installed along its vertical center line via spring A. On joint A, a disassembly part is movably installed along its vertical center line via spring B. A traction part is movably installed horizontally in joint A. A suction platform for sucking the traction part is reserved on joint A at the outer circle of the disassembly part. An inclined installation port is reserved in joint A, and a self-movable sphere is installed in the installation port. A guiding platform cooperating with the sphere is installed on ring A;

[0009] When the joint A and the joint B are assembled firmly, the joint A can press the movable column to expand the leak-proof part and make the inner surface of the leak-proof part closely adhere to the outer surface of the protective sleeve A. The pressing ring A and the ring B can be engaged with each other to perform a fastening connection on the joint A and the joint B;

[0010] When the suction table is at the top of the joint A and pulls the disassembly part outward and returns the disassembly part, the disassembly part can press the traction part to drive the ring A and the ring B to separate via the guiding table by the sphere.

[0011] Furthermore, a channel A for the disassembly part to move and a channel B for the traction part to move are reserved in the joint A, and the placement port is connected to the channel A and the channel B.

[0012] Furthermore, the suction table is at the top of the channel B.

[0013] Furthermore, the side of the placement port farther from the channel B is at the side of the suction table farther from the joint B, and the placement port is arranged obliquely towards the outside of the joint A.

[0014] Furthermore, a number of teeth B are reserved on the outer peripheral surface of the ring B, a guiding wall B is reserved on the teeth B, a number of teeth A are reserved on the inner peripheral surface of the ring A, and a guiding wall A that cooperates with the guiding wall B is reserved on the teeth A.

[0015] Furthermore, a contact wall that cooperates with the sphere is reserved on one side of the traction part, a pressing surface is reserved on the other side of the traction part, a cooperation surface that cooperates with the pressing surface on the traction part is reserved on the side of the disassembly part close to the joint B, a sleeve is arranged on the side of the disassembly part farther from the joint B, and both the contact wall and the pressing surface are arched.

[0016] Furthermore, an obliquely arranged guiding wall C and a partition wall are reserved on the guiding table. When the sphere presses the guiding wall C towards one side, the ring A can move towards the side away from the ring B.

[0017] Furthermore, when the joint A and the joint B are fastened, the traction part presses the disassembly part under the cooperation of the suction table, and the sphere is in the placement port under the restraint of the traction part;

[0018] When the joint A and the joint B are disassembled, the sphere is at the bottom of the traction part.

[0019] Furthermore, the movable column is connected to the joint B through the tower spring C.

[0020] Furthermore, the protective part includes a pair of protective tubes that can be movably arranged on the optical fiber A and the optical fiber B. The opposite sides of the protective tubes are fixedly connected with magnetic attraction rings, and the magnetic attraction rings attract each other.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention enables the assembly of joint A and joint B to be more stable through the cooperation of ring A and ring B; when disassembling connecting part A and connecting part B, it can be completed by pulling the disassembly part. Moreover, when joint A and joint B are in the connected state and in the disassembled state, the sleeve is always in close contact with the wall surface of joint A, preventing the unintentional touch of the sleeve from causing the disassembly of joint A and joint B, ensuring the stability of the connection part between joint A and joint B, and making it very convenient to use.

[0023] 2. After the assembly of optical fiber A and optical fiber B is completed in the present invention, a pair of protective tubes are pushed to approach each other, and then they are attracted to each other through a pair of magnetic attraction rings, so that the pair of protective tubes are sleeved outside the connecting component to protect the connecting component. When disassembling optical fiber A and optical fiber B, directly pull the pair of protective tubes in both directions, and the pair of magnetic attraction rings are separated from each other, and then the disassembly of optical fiber A and optical fiber B can be carried out, which is very convenient to use.

[0040] Refer to Figure 1 and Figure 2 According to this, an embodiment of the present invention provides a portable optical fiber connector, including an optical fiber A1 and an optical fiber B2. The optical fiber A1 and the optical fiber B2 are connected to each other through a connecting component. A protective part 5 is movably installed on the optical fiber A1 and the optical fiber B2, and the connecting component is located inside the protective part 5.

[0041] Refer to Figure 3 andFigure 4 The connecting component includes a connecting part A and a connecting part B. The connecting part B includes a connector B4 fixedly connected to the optical fiber A1, a protective sleeve B41 installed inside the connector B4, and a connecting part tube 42. The connecting part tube 42 is installed inside the protective sleeve B41 and is electrically connected to the optical fiber A1. The connecting part A includes a connector A3 threadedly connected to the connector B4, a protective sleeve A31 screwed inside the connector A3, and an optical fiber core 32 installed inside the protective sleeve A31. The other side of the connector A3 is fixedly connected to the optical fiber B2, and the optical fiber B2 is electrically connected to the optical fiber core 32. The optical fiber core 32 can be inserted into the connecting part tube 42 and be electrically connected to each other.

[0042] Refer to Figure 4 、 Figure 7 、 Figure 8 and Figure 11 Inside the connection part of the connector B4, a leak-proof part 43 and a ring B44 are fixedly connected. The leak-proof part 43 is a ring-shaped and hollow rubber ring. The leak-proof part 43 is located between the protective sleeve B41 and the ring B44. A variable column 45 for expanding the leak-proof part 43 is movably installed at the connection part of the connector B4. One end of the variable column 45 is fixedly connected to a rubber platform. The variable column 45 is connected to the connection part of the connector B4 through a tower spring C451. Initially, the connector A3 does not press the variable column 45, and the leak-proof part 43 is filled with air.

[0043] Refer to Figures 4 - 9 、 Figure 11 and Figure 12 Inside the connection part of the connector A3, a ring-shaped variable piece 330 is movably installed along its vertical center line. One side of the variable piece 330 facing the connector B4 is fixedly connected to a ring A33 that cooperates with the ring B44. The side of the variable piece 330 farther from the connector B4 is connected to the connection part of the connector A3 through a tower spring A331. A number of teeth B441 are reserved on the outer peripheral surface of the ring B44, and a guiding wall B4411 is reserved on the teeth B441. A number of teeth A332 are reserved on the inner peripheral surface of the ring A33, and a guiding wall A3321 that cooperates with the guiding wall B4411 is reserved on the teeth A332. A ring-shaped disassembling part 34 is movably installed on the connector A3 along its vertical center line through a tower spring B341. A sleeve 342 is installed on the side of the disassembling part 34 farther from the connector B4. A channel A301 for the movement of the disassembling part 34 is reserved in the connector A3. Initially, under the cooperation of the tower spring B 341, the sleeve 342 is in close contact with the connector A3.

[0044] Refer to Figures 4 - 7 、 Figure 9 and Figure 10, a traction part 35 is movably installed along the horizontal direction in the connector A3. A channel B302 for the movement of the traction part 35 is reserved in the connector A3. A suction table 36 for sucking the traction part 35 is reserved at the outer circle of the disassembly part 34 on the connector A3. The suction table 36 is a permanent magnet. The suction table 36 is located at the top of the channel B302. An inclined installation port 303 is reserved in the connector A3. A movable sphere 37 is installed in the installation port 303. A guiding table 38 cooperating with the sphere 37 is fixed on the outer peripheral surface of the movable piece 330; the installation port 303 is communicated with the channel A301 and the channel B302. The side of the installation port 303 farther from the channel B302 is located at the side of the suction table 36 farther from the connector B4, and the installation port 303 is inclined towards the outside of the connector A3; a contact wall 351 cooperating with the sphere 37 is reserved on one side of the traction part 35, and a pressing surface 352 is reserved on the other side of the traction part 35. A cooperating surface 343 cooperating with the pressing surface 352 on the traction part 35 is reserved on the side of the disassembly part 34 close to the connector B4. Both the contact wall 351 and the pressing surface 352 are arched. An inclined guiding wall C381 and a partition wall 382 are reserved on the guiding table 38. When the sphere 37 presses the guiding wall C381 towards one side, the ring A33 can move towards the side away from the ring B44, facilitating the disassembly between the ring A33 and the ring B44.

[0045] Refer to Figure 1 And Figure 2 , the protective part 5 includes a pair of protective tubes 51 movably installed on the optical fiber A1 and the optical fiber B2. Magnetically attracting rings 52 are fixed on the opposite sides of the protective tubes 51, and the pair of magnetically attracting rings 52 attract each other.

[0046] After the optical fiber A1 and the optical fiber B2 are assembled, push the pair of protective tubes 51 to make them approach each other, and then attract each other through the pair of magnetically attracting rings 52, so that the pair of protective tubes 51 are sleeved outside the connecting part, thereby protecting the connecting part. When disassembling the optical fiber A1 and the optical fiber B2, directly pull the pair of protective tubes 51 towards both sides, and the pair of magnetically attracting rings 52 are separated from each other, and then the optical fiber A1 and the optical fiber B2 can be disassembled, which is very convenient to use.

[0047] The specific implementation method is as follows: Taking the case where the suction table 36 is at the top as an example, at the beginning, when the connector A3 and the connector B4 are not connected together, under the cooperation of the tower spring B 341, the sleeve 342 on the disassembly part 34 is in close contact with the wall surface of the connector A3, and the disassembly part 34 blocks one side outside the channel B302. Under the cooperation of the suction table 36, the pressing surface 352 on the traction part 35 faces outwards and is in close contact with the inner surface of the disassembly part 34. The sphere 37 is located in the installation port 303 under the restraint of the traction part 35;

[0048] Then, insert the connection between joint A3 and joint B4. Next, keep joint B4 on one side stationary and rotate joint A3 towards one side to assemble joint A3 and joint B4. During this period, ring A33 slowly approaches ring B44, and joint A3 slowly presses the variable column 45, and the optical fiber core 32 can be inserted into the connection part tube 42. When ring A33 and ring B44 are in close contact, as joint A3 continues to rotate, the tower spring A331 shortens under pressure. When the tooth A332 is aligned with the position between a pair of teeth B441, the tower spring A331 can press ring A33 and ring B44 to perform the embedding. At this moment, joint A3 cannot rotate in the reverse direction. Due to the cooperation of the guiding wall B4411 and the guiding wall A3321, joint A3 can continue to rotate to make the connection between joint A3 and joint B4 more stable. Joint A3 presses the variable column 45 to expand the leak-proof part 43 and make the inner surface of the leak-proof part 43 closely adhere to the outer surface of the protective sleeve A31, thereby achieving the isolation of the area of the connection between the optical fiber core 32 and the connection part tube 42 from the outside. When joint A3 rotates to the farthest point towards one side, cancel the rotation of joint A3. At this moment, the connection between joint A3 and joint B is very stable, and ring A33 and ring B44 are embedded with each other to prevent joint A3 and joint B4 from separating from each other;

[0049] When disassembling the connection part A and the connection part B, rotate the connection part A and the connection part B together to make the suction table 36 located at the top of joint A3. Then, pull the sleeve 342 towards the side away from joint B4 to remove the disassembly part 34 and cancel the blockage of the outer side of the channel B302. At this moment, the suction table 36 can suck the traction part 35 to make the traction part 35 and the suction table 36 in close contact. At this moment, the traction part 35 is removed, and the restraint on the sphere 37 in the placement port 303 is cancelled. The sphere 37 slides into the channel B302 and is located at the bottom of the traction part 35. At this moment, the sphere 37 is in contact with the guiding wall C381;

[0050] Then, pull the sleeve 342 towards the side close to joint B4 to make the sleeve 342 and the outer wall surface of joint A3 in close contact again. During this period, the disassembly part 34 can press the pressing surface 352 through the cooperation surface 343 to make the traction part 35 change inward. Then, the traction part 35 can press the sphere 37 through the contact wall 351 to make the sphere 37 smoothly pressed inside, and then press the guiding wall C381 to make the ring A33 move towards the side away from the ring B44 and disassemble from the ring B44. Then, the joint A3 can be rotated in the reverse direction to achieve the disassembly of the connection part A and the connection part B;

[0051] After the disassembly of the connection part A and the connection part B is completed, under the cooperation of the tower spring C451, the variable column 45 and the leak-proof part 43 return to their original shapes;

[0052] Next, rotate the connecting part A to place the suction table 36 at the top of the joint A3, and then pull the sleeve 342 outwards to separate the sleeve 342 from the wall surface of the joint A3, which allows the disassembling part 34 to be removed and cancels the blockage of the outer side of the channel B302. At this time, the suction table 36 can attract the traction part 35 to make the traction part 35 in close contact with the suction table 36. Then, adjust the connection of the joint A3 to be vertically upwards. At this moment, the sphere 37 slides back into the placement opening 303 under its own weight. Then, pull the sleeve 342 to make the sleeve 342 in close contact with the wall surface of the joint A3 again. At this time, with the cooperation of the suction table 36, the pressing surface 352 on the traction part 35 contacts the inner surface of the disassembling part 34 outwards, and the sphere 37 is constrained by the traction part 35 in the placement opening 303 and returns to the starting position.
