Description

Technical Field

[0001] The invention relates to the technical field of optical fiber active connectors, in particular to a quick-plug optical fiber active connector. Background Art

[0002] Fiber optic connectors are key passive components used to connect two optical fibers or between an optical fiber and an optical device to achieve detachable and repeatable connections of optical signals. They are widely used in optical fiber communications, data centers, local area networks, industrial control, and other fields, with the characteristics of low loss, high reliability, and easy installation and maintenance.

[0003] After searching, the Chinese patent with the announcement number CN221572870U discloses a waterproof optical fiber connector, including an optical fiber connector female head and an optical fiber connector male head, a No. 1 waterproof structure is installed on the optical fiber connector male head, a No. 2 waterproof structure is installed in the No. 1 waterproof structure, the No. 2 waterproof structure is composed of a sealing rubber airbag and a sealing support spring, and there are several sealing support springs that are symmetrically installed in the sealing rubber airbag. By arranging the No. 1 waterproof structure on the optical fiber connector male head and arranging the No. 2 waterproof structure in the No. 1 waterproof structure, and making the No. 1 waterproof structure and the No. 2 waterproof structure cooperate at the same time, the plug-in place of the optical fiber connector female head and the optical fiber connector male head can be sealed, so as to improve the waterproof effect of the plug-in place of the optical fiber connector female head and the optical fiber connector male head, and then make the plug-in place of the optical fiber connector female head and the optical fiber connector male head not easy to enter water, but this scheme still has the following shortcomings when actually used: In the scheme, a protective cover is usually set on the outside of the male end connecting tube to protect the internal delicate connection structure from the influence of the external environment such as dust, moisture, etc. However, in actual operation, when the female connector and the male connector are docked, these protective covers are often removed and discarded after completing their initial installation task. Once the female connector and the male connector need to be separated for necessary inspection, cleaning or maintenance, the connecting tube without the protection of the protective cover will be directly exposed to the external environment and easily contaminated with dust, impurities or other contaminants. This may not only cause damage to the optical fiber connection surface and reduce the quality and stability of signal transmission, but also may cause poor contact due to the presence of dust and other impurities during reconnection, increase signal loss, and affect the stability and reliability of the entire optical fiber communication system.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-8 , a quick-plug optical fiber active connector, including a main unit and an installation unit; Among them, the main unit includes a connector body 11, a core 12 is arranged on the inner side of the connector body 11, a protective cap 13 corresponding to the core 12 is sleeved on the outer wall of the connector body 11, a pressure cover 14 is rotatably installed on the side of the connector body 11, a tail port 15 is arranged on the end of the connector body 11 and the side of the pressure cover 14, a connecting pipe is arranged at one end of the connector body 11 away from the tail port 15, a connecting flange 16 corresponding to the connecting pipe is arranged at the end of the connector body 11, a tail cylinder 17 is arranged on the outer wall of the two tail ports 15, and a threaded sleeve screwed to the tail port 15 is rotatably installed on the end of the tail cylinder 17.

[0030] When in use, the staff can first process the connecting end of the optical fiber, perform operations such as stripping and gluing on the connecting end of the optical fiber, and after the processing is completed, the staff can open the pressure cover 14 to expose the core 12, and then put the tail cylinder 17 on the optical fiber, and place the connecting end of the optical fiber in the tail port 15 and insert the processed part into the core 12, and the staff can cover the pressure cover 14 so that the two tail ports 15 are aligned. At this time, the tail cylinder 17 is slid and put on the outer walls of the two tail ports 15, and the tail cylinder 17 is screwed to the tail port 15. Therefore, the tail cylinder 17 can be rotated when the two are connected to achieve screw connection, ensuring that the tail cylinder 17 can be stably put on the outer wall of the tail port 15, and the two tail ports 15 and the pressure cover 14 are firmly fixed.

[0031] The mounting unit includes four brackets 21 fixedly mounted on the side of the connector body 11 and located outside the connecting tube and distributed in a circular array. A shaft rod 22 is rotatably mounted on the inner wall of the bracket 21. A connecting block 23 is fixedly mounted on the outer wall of the shaft rod 22. A dust cover 24 is fixedly mounted on the end of the connecting block 23. The dust cover 24 is set in a quarter-cylinder shape. A torsion spring 25 is mounted on the end of the shaft rod 22. The two ends of the torsion spring 25 are respectively fixedly connected to the bracket 21 and the shaft rod 22. The inner wall of the connecting flange 16 is provided with four receiving grooves 26 distributed in a circular array and corresponding to the dust cover 24.

[0032] An opening and closing assembly corresponding to the dust cover 24 is provided on the inner side of the connecting flange 16, and the opening and closing assembly includes guide grooves 31 respectively opened on the four inner walls of the connecting flange 16, and guide blocks 32 are slidably installed on the inner walls of the four guide grooves 31, and vertical rods 33 adapted to the connecting blocks 23 are fixedly installed on the sides of the four guide blocks 32. Four clearance grooves 34 corresponding to the vertical rods 33 are opened at the end of the connector body 11, and two convex bumps 35 are symmetrically fixedly installed at one end of the vertical rod 33 away from the guide block 32, and two card slots 36 corresponding to the convex bumps 35 are symmetrically opened on the inner wall of the clearance groove 34.

[0033] After the optical fiber is connected to the connector body 11, the staff can insert the connector body 11 into the connecting flange 16. Before the insertion, the outer wall of the connecting tube at the end of the connector body 11 is protected by four dust cover plates 24. The four dust cover plates 24 are located on the outside of the connecting tube to prevent it from being affected by dust, etc. As the connecting tube is inserted into the connecting flange 16, first, the vertical rod 33 in the connecting flange 16 can contact the connecting block 23. Since the friction between the guide block 32 and the guide groove 31 is greater than the torsion of the torsion spring 25, as the connector body 11 is pushed, the vertical rod 33 can push the connecting block 23 and drive the dust cover plates 24 and the shaft rod 22 to rotate, so that the four dust cover plates 24 can be opened to expose the connecting tube. At this time, the vertical rod 33 can enter the make way groove 34, and under the engagement of the convex bump 35 and the card slot 36, the vertical rod 33 can be stably located in the make way groove 34. As the connector body 11 continues to be pushed, it can drive The vertical rod 33 and the guide block 32 slide along the guide groove 31, and after the connection between the connector body 11 and the connecting flange 16 is completed, the dust cover 24 can enter the receiving groove 26 to be placed, and the connector body 11 and the connecting flange 16 can be connected by a card plate and a bayonet. The connection method and working principle of the card plate and the bayonet are existing mature technologies and are not described in detail here; and in the process of pulling out the connecting flange 16 from the connector body 11, the card plate is first toggled to separate from the bayonet to release the limit on the connector body 11. Under the engagement of the convex bump 35 and the card groove 36, the connector body 11 can drive the vertical rod 33 and the guide block 32 to slide in the opposite direction along the guide groove 31 when it moves, and when the guide block 32 moves to the end of the guide groove 31, the vertical rod 33 can move out of the clearance groove 34, and when the connecting block 23 is separated from the vertical rod 33, the shaft rod 22 and the dust cover 24 can be reversed under the action of the torsion spring 25 to attach the connecting pipe package to the inside to avoid being affected by dust and the like.

[0034] A sealing assembly is provided on the connecting flange 16, and the sealing assembly includes four guide openings 41 respectively opened on the side of the connecting flange 16, and the guide openings 41 are connected to the guide grooves 31, a sliding frame 42 is slidably installed on the outer wall of the connecting flange 16, and the inner wall of the sliding frame 42 is fixedly connected to the guide block 32 through the guide openings 41, a U-shaped groove 1 43 is opened on the side of the connecting flange 16, and an elastic airbag ring 44 is arranged on the inner wall of the U-shaped groove 1 43, an extrusion frame 45 adapted to the elastic airbag ring 44 is fixedly installed on the side of the sliding frame 42, a U-shaped groove 2 46 is opened on the inner wall of the connecting flange 16, and a sealing airbag ring 47 is arranged on the inner wall of the U-shaped groove 2 46, the elastic airbag ring 44 and the sealing airbag ring 47 are both arranged in a U-shaped shape, and the elastic airbag ring 44 and the sealing airbag ring 47 are connected through a conduit 48.

[0035] During the process of inserting the connector body 11 into the connecting flange 16, the guide block 32 can move and drive the sliding frame 42 to slide through the guide port 41. When the connector body 11 is in place, the extrusion frame 45 can squeeze the elastic airbag ring 44 in the mouth-shaped groove 1 43. When the elastic airbag ring 44 is squeezed, the gas inside the elastic airbag ring 44 can enter the sealing airbag ring 47 through the conduit 48. After the sealing airbag ring 47 is inflated, it can expand the outlet-shaped groove 2 46 and block the gap between the connecting flange 16 and the connector body 11. At the same time, the connector body 11 can be fixed by using the card plate and the bayonet, and the elastic airbag ring 44 can be in an extruded state, thereby ensuring the sealing of the connector body 11 and the connecting flange 16 when connected.

[0036] A limiting assembly is provided at the end of the tail cylinder 17, and the limiting assembly includes an annular groove 51 opened on the inner wall of the end of the tail cylinder 17, and four elastic sheets 52 distributed in a circular array are fixedly installed on the inner wall of the annular groove 51, and the elastic sheets 52 are arranged in an arc shape, and the opposite sides of the four elastic sheets 52 are fixedly installed with clamping blocks 53, and the end of the clamping block 53 away from the elastic sheet 52 is provided with anti-slip grooves, and a sliding sleeve 54 is slidably installed on the inner wall of the end of the tail cylinder 17, and the end of the elastic sheet 52 away from the connection with the annular groove 51 is fixedly connected to the side of the sliding sleeve 54, and an opening 55 connected to the annular groove 51 is opened on the inner wall of the tail cylinder 17, and a top rod 56 adapted to the opening 55 is fixedly installed on the side of the tail port 15.

[0037] In the process of connecting the tail cylinder 17 with the tail port 15, the tail cylinder 17 needs to be aligned first so that the push rod 56 on the side of the tail port 15 can be inserted into the opening 55. As the tail cylinder 17 rotates, the tail cylinder 17 can move along the tail port 15 under the action of the thread, and the push rod 56 can approach the sliding sleeve 54. As the tail cylinder 17 is twisted, the push rod 56 can contact the sliding sleeve 54 and push the sliding sleeve 54 so that the sliding sleeve 54 and the tail cylinder 17 move in opposite directions. When the sliding sleeve 54 moves, the two ends of the elastic sheet 52 are fixedly connected to the annular groove 51 and the sliding sleeve 54 respectively. Therefore, when the sliding sleeve 54 moves, the elastic sheet 52 can push the elastic sheet 52 to move the sliding sleeve 54. The sheet 52 is stretched so that the elastic sheet 52 is gradually straightened. When the tail cylinder 17 is in place, the four elastic sheets 52 can be gradually deformed until the side blocks 53 fit the outer wall of the optical fiber with a certain extrusion force. At this time, under the action of the anti-slip grooves at the ends of the blocks 53, the friction between the blocks 53 and the outer wall of the optical fiber can be increased, so that the optical fiber can be firmly connected to the connector body 11; and in the process of use, if the optical fiber located on the outside of the tail cylinder 17 is pulled, the block 53 can be driven to move when the optical fiber moves under the action of the friction force, and when the block 53 moves, the elastic sheet 52 has a certain elasticity and can therefore prevent the optical fiber from being pulled outward, thereby ensuring the stability of the optical fiber when in use.

[0038] The specific working principle of the present invention is as follows: When in use, the staff can first process the connecting end of the optical fiber, perform operations such as stripping and gluing on the connecting end of the optical fiber, and after the processing is completed, the staff can open the pressure cover 14 to expose the core 12, and then put the tail cylinder 17 on the optical fiber, and place the connecting end of the optical fiber in the tail port 15 and insert the processed part into the core 12, and the staff can cover the pressure cover 14 so that the two tail ports 15 are aligned. At this time, the tail cylinder 17 is slid and put on the outer walls of the two tail ports 15, and the tail cylinder 17 is screwed to the tail port 15. Therefore, the tail cylinder 17 can be rotated when the two are connected to achieve screw connection, ensuring that the tail cylinder 17 can be stably put on the outer wall of the tail port 15, and the two tail ports 15 and the pressure cover 14 are firmly fixed.

[0039] In the process of connecting the tail cylinder 17 with the tail port 15, the tail cylinder 17 needs to be aligned first so that the push rod 56 on the side of the tail port 15 can be inserted into the opening 55. As the tail cylinder 17 rotates, the tail cylinder 17 can move along the tail port 15 under the action of the thread, and the push rod 56 can approach the sliding sleeve 54. As the tail cylinder 17 is twisted, the push rod 56 can contact the sliding sleeve 54 and push the sliding sleeve 54 so that the sliding sleeve 54 and the tail cylinder 17 move in opposite directions. When the sliding sleeve 54 moves, the two ends of the elastic sheet 52 are fixedly connected to the annular groove 51 and the sliding sleeve 54 respectively. Therefore, when the sliding sleeve 54 moves, the elastic sheet 52 can push the elastic sheet 52 to move the sliding sleeve 54. The sheet 52 is stretched so that the elastic sheet 52 is gradually straightened. When the tail cylinder 17 is in place, the four elastic sheets 52 can be gradually deformed until the side blocks 53 fit the outer wall of the optical fiber with a certain extrusion force. At this time, under the action of the anti-slip grooves at the ends of the blocks 53, the friction between the blocks 53 and the outer wall of the optical fiber can be increased, so that the optical fiber can be firmly connected to the connector body 11; and in the process of use, if the optical fiber located on the outside of the tail cylinder 17 is pulled, the block 53 can be driven to move when the optical fiber moves under the action of the friction force, and when the block 53 moves, the elastic sheet 52 has a certain elasticity and can therefore prevent the optical fiber from being pulled outward, thereby ensuring the stability of the optical fiber when in use.

[0040] After the optical fiber is connected to the connector body 11, the staff can insert the connector body 11 into the connecting flange 16. Before the insertion, the outer wall of the connecting tube at the end of the connector body 11 is protected by four dust cover plates 24. The four dust cover plates 24 are located on the outside of the connecting tube to prevent it from being affected by dust, etc. As the connecting tube is inserted into the connecting flange 16, the vertical rod 33 in the connecting flange 16 can first contact the connecting block 23. Since the friction between the guide block 32 and the guide groove 31 is greater than the torsion of the torsion spring 25, as the connector body 11 is pushed, the vertical rod 33 can push the connecting block 23 and drive the dust cover plate 24 and the shaft 22 to move. Rotate so that the four dust cover plates 24 can be opened to expose the connecting pipe. At this time, the vertical rod 33 can enter the make way groove 34, and under the engagement of the convex bump 35 and the card slot 36, the vertical rod 33 can be stably located in the make way groove 34. As the connector body 11 continues to be pushed, the vertical rod 33 and the guide block 32 can be driven to slide along the guide groove 31. After the connection between the connector body 11 and the connecting flange 16 is completed, the dust cover plate 24 can enter the receiving groove 26 for placement, and at this time, the connector body 11 and the connecting flange 16 can be connected by a card plate and a bayonet. The connection method and working principle of the card plate and the bayonet are existing mature technologies and will not be elaborated here.

[0041] In the process of pulling out the connecting flange 16 from the connector body 11, the card plate is first pushed and separated from the card slot to release the limit on the connector body 11. Under the engagement of the convex bump 35 and the card slot 36, the connector body 11 can drive the vertical rod 33 and the guide block 32 to slide in the opposite direction along the guide groove 31 when it moves, and when the guide block 32 moves to the end of the guide groove 31, the vertical rod 33 can move out of the clearance groove 34. When the connecting block 23 is separated from the vertical rod 33, the shaft rod 22 and the dust cover plate 24 can be reversed under the action of the torsion spring 25 to attach the connecting pipe package to the inside to avoid being affected by dust and the like.

[0042] During the process of inserting the connector body 11 into the connecting flange 16, the guide block 32 can move and drive the sliding frame 42 to slide through the guide port 41. When the connector body 11 is in place, the extrusion frame 45 can squeeze the elastic airbag ring 44 in the mouth-shaped groove 1 43. When the elastic airbag ring 44 is squeezed, the gas inside the elastic airbag ring 44 can enter the sealing airbag ring 47 through the conduit 48. After the sealing airbag ring 47 is inflated, it can expand the outlet-shaped groove 2 46 and block the gap between the connecting flange 16 and the connector body 11. At the same time, the connector body 11 can be fixed by using the card plate and the bayonet, and the elastic airbag ring 44 can be in an extruded state, thereby ensuring the sealing of the connector body 11 and the connecting flange 16 when connected.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
