Description

Technical Field

[0001] The invention relates to the technical field of optical fiber connectors, and in particular to a locking mechanism for an optical fiber active connector. Background Art

[0002] A fiber optic connector is a device that makes a detachable (movable) connection between optical fibers. It precisely connects the two end faces of the optical fiber to maximize the coupling of the light energy output by the transmitting optical fiber to the receiving optical fiber and minimizes the impact on the system due to its involvement in the optical link. This is the basic requirement of a fiber optic connector. To a certain extent, the fiber optic connector affects the reliability and performance of the optical transmission system.

[0003] For example, a Chinese patent (CN220872706U) discloses an optical fiber connector, including a sleeve component, a clamping component, and two fixing components, wherein the sleeve component is adapted to the clamping component, and the opposite ends of the sleeve component and the clamping component are respectively connected to two left-right symmetrical fixing components. The clamping plate in the semicircular tough plate is squeezed by a threaded ring to contact and squeeze the optical fiber on the card slot, thereby clamping and fixing the optical fiber, thereby improving its connection tensile strength.

[0004] Since there is an extrusion limiter between the clamping plate and the optical fiber line, when the external optical fiber line is suddenly pulled greatly during use, the optical fiber line is easily broken, thereby affecting the use of the optical fiber; and the existing optical fiber connectors are mostly plug interface type connections.

[0039] The following will refer to Figures 1 to 15 Various embodiments of the present invention are described in detail.

[0040] A locking mechanism for an optical fiber connector, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Fig.12 , Fig.14 As shown, it includes a left locking end 1 and a right locking end 2, the left locking end 1 and the right locking end 2 are circular ring structures, a plurality of locking openings 3 are evenly opened on the right end circumferential edge side of the left locking end 1, three locking openings 3 are set here, the right side and the top side of the locking opening 3 are mutually penetrating, a plurality of built-in openings 4 are evenly opened on the left end circumferential edge side of the right locking end 2, three built-in openings 4 are set here, the built-in openings 4 can correspond to the locking openings 3 during use, each of the built-in openings 4 is slidably connected with a plug plate 5 inside, the plug plate 5 extends outward, and the plug plate 5 can slide up and down inside the built-in opening 4, each of the left end outer side of the plug plate 5 is respectively fixedly connected with a card block 6, the outer side of the card block 6 is provided with an inclined surface, and the card block 6 is arranged on the left side of the right locking end 2, and a pressing rod hole that penetrates each built-in opening 4 is opened on the right locking end 2, a pressing rod 7 is slidably installed inside the pressing rod hole, and the pressing rod 7 is fixedly connected to the corresponding plug plate 5;

[0041] Each of the pressing rods 7 is respectively sleeved with a pressing spring 8, one end of the pressing spring 8 is fixedly connected to the plug plate 5, and the other end is fixedly connected to the inner top wall of the built-in port 4. Under normal circumstances, the pressing spring 8 is in a contracted state, and the interiors of the left locking end 1 and the right locking end 2 are respectively penetrated by installation cavities on the left and right, and the interior of each installation cavity is respectively fixedly connected with a positioning circular plate 9, and a certain distance is reserved between the right end face of the left locking end 1 and the positioning circular plate 9, and a certain distance is reserved between the left end face of the right locking end 2 and the positioning circular plate 9, and the interior of each installation cavity is respectively fixedly connected with a fixed circular plate 10, which is arranged on the outer side of the positioning circular plate 9 on the same side, and a component cavity is provided between the fixed circular plate 10 and the positioning circular plate 9 on the same side, and an automatic locking device is provided inside each component cavity, and the left side of the left locking end 1 and the right locking end 2 are respectively provided with a fixed circular plate 10. A positioning ring 11 is fixedly connected to the right end of the positioning circular plate 9, and a terminal 14 that penetrates the positioning circular plate 9 is fixedly connected inside the positioning ring 11. The optical fiber 13 is wound and fixed on the left end of the terminal 14 after the insulation layer is removed. A plug shaft 12 is fixedly connected to the left end of the positioning circular plate 9 on the right side, and the plug shaft 12 can be completely and appropriately inserted into the interior of the positioning ring 11. The interior of the plug shaft 12 is provided with an inner cavity that passes through the left and right sides, and the interior of the inner cavity is fixedly connected with the terminal 14. The terminal 14 can be selected from existing suitable components. The optical fiber 13 is wound and fixed on the right end of the terminal 14 after the insulation layer is removed. Pins are fixedly connected to the other ends of the two terminal 14, respectively, and the pins can be replaced with other existing suitable components. The outer ends of the left locking end 1 and the right locking end 2 are respectively provided with protective devices.

[0042] When it is necessary to install the two optical fiber lines 13, the personnel first peel off the insulation skins on the outer sides of the two optical fiber lines 13, and wind the two optical fibers around the two terminal ends 14 respectively, so that the left locking end 1 approaches and contacts the right locking end 2, and the inclined surface of the card block 6 contacts the inner top wall of the corresponding locking port 3, thereby driving the three card blocks 6 to approach the plug shaft 12, compressing the pressing spring 8, inserting the three plug plates 5 into the corresponding locking ports 3, and inserting the plug shaft 12 into the positioning ring 11, and inserting the left pin into the inner cavity of the plug shaft 12. When the left locking end 1 and the right locking end 2 are in close contact, the two pins are in contact at this time, realizing the transmission of optical fiber signals. Due to the reaction force of the pressing spring 8, the card blocks 6 are respectively stuck in the outer ports of the corresponding locking ports 3, thereby realizing the locking effect of the left locking end 1 and the right locking end 2;

[0043] When the left locking end 1 and the right locking end 2 are pulled, the block 6 is stuck in the locking opening 3, so the left locking end 1 and the right locking end 2 will not separate and fall off, thereby improving the transmission effect of the optical fiber and ensuring the stability and reliability of the signal. The setting of the plug shaft 12 and the positioning ring 11 can accurately connect the two pins to realize the transmission of optical signals. If the optical fiber connection fails, the connector can be quickly replaced to solve the problem, making the installation and maintenance process more convenient and further reducing the cost.

[0044] When the left locking end 1 and the right locking end 2 need to be separated, the person holds the pressing rod 7 at the same time, and the plug plate 5 slides along the built-in opening 4, pressing the spring 8 to stretch, so that the block 6 can be taken out of the locking opening 3.

[0045] like Fig. 9 , Fig.10 , Fig.11 As shown, the automatic locking device includes a built-in cylinder 15, and the built-in cylinder 15 is fixedly connected between the positioning circular plate 9 and the fixed circular plate 10 on the same side. A plurality of limiting boxes 16 are evenly fixedly connected on the outer end surface of the built-in cylinder 15. Three limiting boxes 16 are provided here, and a sliding block 17 is slidably connected to the interior of each of the limiting boxes 16. An extrusion rod 19 is fixedly connected to the inner end of each of the sliding blocks 17, and an extrusion bar 20 is fixedly connected to the other end of each of the extrusion rods 19. A tension spring 18 is fixedly connected to the top end of each of the sliding blocks 17, and the other end of each of the tension springs 18 is fixedly connected to the top end of the corresponding limiting box 16. The three extrusion bars 20 are provided in the corresponding built-in cylinders 15, and a driving device is provided on the outer side of each of the limiting boxes 16.

[0046] like Fig.10 , Fig.11 As shown, the driving device includes a sliding box 21, and three positioning grooves 22 are respectively opened on the inner walls of the left locking end 1 and the right locking end 2. The positioning grooves 22 are arranged between the fixed circular plate 10 and the positioning circular plate 9. Each positioning groove 22 on the left side is respectively arranged between every two locking ports 3, and each positioning groove 22 on the right side is respectively arranged between every two built-in ports 4. The interior of each positioning groove 22 is respectively connected to the sliding box 21 for sliding left and right movement. Each sliding box 21 is respectively opened with an oblique slot hole 23 (the structure of the oblique slot hole 23 is as shown in FIG. Fig.10As shown in the figure), the top of the oblique slot hole 23 on the left side is inclined to the left, and the bottom end is inclined to the right; the top of the oblique slot hole 23 on the right side is inclined to the right, and the bottom end is inclined to the left; a lifting rod 24 is fixed to the top of each sliding block 17, and the top end of the lifting rod 24 is slidably connected to the corresponding sliding box 21 up and down; a sliding shaft 25 is fixedly connected to each lifting rod 24, and the sliding shaft 25 is slidably connected to the corresponding oblique slot hole 23; three built-in holes 26 are respectively opened on the right end surface of the left locking end 1 and the left end surface of the right locking end 2, and the built-in holes 26 are connected to the corresponding positioning groove 22; a driving block 27 is respectively slidably connected to the inside of each built-in hole 26, and a push rod 28 is fixedly connected to each driving block 27, and the other end of each push rod 28 is respectively fixedly connected to the corresponding sliding box 21;

[0047] After the personnel install the optical fiber line 13 inside the two built-in tubes 15, the left locking end 1 gradually approaches the right locking end 2, and the driving block 27 on the left and the driving block 27 on the right will squeeze each other. Each driving block 27 slides along the corresponding built-in hole 26 respectively, and the push rod 28 pushes the corresponding sliding box 21 to slide, and the sliding shaft 25 slides downward along the corresponding inclined slot hole 23. Each lifting rod 24 pushes the sliding block 17 to approach the optical fiber line 13, and the tension spring 18 gradually stretches. When the left locking end 1 and the right locking end 2 are completely locked, each squeezing rod 19 at this time pushes the corresponding squeezing strip 20 to squeeze the insulation layer of the optical fiber line 13, thereby achieving the clamping effect on the optical fiber line 13. When the external optical fiber line 13 is pulled, the three squeezing strips 20 on the same side clamp the optical fiber line 13, and the optical fiber will not be separated from the terminal 14, which will not affect the use of the optical fiber. At the same time, it can also prevent the optical fiber from being damaged, providing a certain protection effect.

[0048] like Figure 1 , Figure 7 , Fig.13 As shown, the protection device includes a protection tube 29, a driving ring 30 is fixedly connected to the left end of the left locking end 1 and the right end of the right locking end 2, and the other end of each driving ring 30 is fixedly connected to the protection tube 29, and a positioning semicircle 31 is fixedly connected to the inside of each protection tube 29. The positioning semicircle 31 is a semicircular block structure, and the front ends of the two positioning semicircles 31 are respectively provided with a U-shaped cavity, and three telescopic rods 32 are evenly fixedly connected to the inside of the U-shaped cavity of each positioning semicircle 31 (the installation position of the telescopic rod 32 is as shown in FIG. Fig.13As shown in the figure, the other end of each telescopic rod 32 is fixedly connected with a notch block 33, each notch block 33 is slidably connected to the inner surface of the positioning semicircle 31, and each telescopic rod 32 is sleeved with a compression spring 34, one end of the compression spring 34 is fixedly connected to the notch block 33, and the other end is fixedly connected to the inner wall of the U-shaped cavity. Due to the rebound force of the compression spring 34, the top surface of the notch block 33 contacts the inner wall of the U-shaped cavity;

[0049] The personnel hold the optical fiber line 13 and install it inside the openings of the three notch blocks 33 on the same side. The optical fiber line 13 is set up with ups and downs, and finally the optical fiber is fixed on the corresponding terminal 14. When the external optical fiber line 13 is pulled, the optical fiber line 13 will gradually slide out to the outside, and the optical fiber line 13 will drive the notch block 33 to approach the center of the positioning semicircle 31. At this time, the telescopic rod 32 will drive the compression spring 34 to contract, so that the optical fiber line 13 can be extended outward for a part, which plays a buffering and protective role of the optical fiber line 13, and prevents the optical fiber line 13 from breaking when it is suddenly pulled by external force. When the external force disappears, the rebound force of the compression spring 34 drives the telescopic rod 32 and the optical fiber line 13 to return to the initial state.

[0050] like Figure 5 , Figure 6 , Fig.10 As shown, three locking plates 35 are evenly connected to the outer side of the right end of the left locking end 1, and two plug holes are respectively provided on each locking plate 35. A plug rod 36 is slidably connected to each of the built-in holes 26 on the right side, and the plug rod 36 is arranged on the left side of the corresponding driving block 27. The bottom of the plug rod 36 is a round surface, and the plug rod 36 is sleeved with a return spring, one end of the return spring is fixedly connected to the top surface of the built-in hole 26, and the other end is fixedly connected to the middle part of the plug rod 36. An inclined surface 37 is respectively provided on the left end of each driving block 27 on the left side;

[0051] When the left locking end 1 gradually approaches the right locking end 2, the driving block 27 on the left and the driving block 27 on the right will squeeze each other, and each driving block 27 will slide into the corresponding built-in hole 26 respectively, and the inclined surface 37 will slide on the circular surface of the insertion rod 36, thereby driving each insertion rod 36 to slide outward. When the driving block 27 and the driving block 27 on the right contact each other to an appropriate degree, the insertion rod 36 also slides to an appropriate degree at this time, and then the personnel push the three locking plates 35 to buckle on the outer end surface of the right locking end 2, so that the insertion rod 36 is inserted into the corresponding socket, so that the left locking end 1 and the right locking end 2 are locked for the second time, which further improves the stability of the connector.

[0052] like Figure 7 , Figure 8As shown, a tripod 38 is provided inside the outer side of each of the protective tubes 29, and an extension rod 39 is fixedly connected to the inside of the tip of the tripod 38. The three extension rods 39 are arranged close to the center of the protective tube 29, and an extrusion spring is fixedly connected to the bottom end of each extension rod 39. A stabilizing frame is fixedly connected to the other end of each extrusion spring, and a friction wheel 40 is rotatably connected to each stabilizing frame. The three friction wheels 40 on the same side are arranged close to each other, and a clamping mechanism is provided on the inner side of each of the tripods 38.

[0053] like Figure 7 , Figure 8 As shown, the clamping mechanism includes a fixing rod 41, and the inner end of each of the extension rods 39 is respectively fixedly connected with a fixing rod 41, and the other end of each of the fixing rods 41 is respectively fixedly connected with an inclined fixing box 42, and the inner angle between the fixing rod 41 and the fixing box 42 is between 120-150 degrees, preferably 135 degrees, and a limiting cavity 43 is respectively opened inside each of the fixing boxes 42, and the limiting cavity 43 passes through the fixing box 42 up and down, and the inside of each of the limiting cavities 43 is respectively slidably connected with a pressure push shaft 44, and the pressure push shaft 44 can reciprocate along the limiting cavity 43, and a rectangular hole 45 is respectively opened on the side end of each of the fixing boxes 42, and the rectangular hole 45 is arranged to pass through the limiting cavity 43, and each of the pressure push shafts 44 is respectively fixedly connected with a block 46, and the block 46 is slidably connected to the corresponding Inside the rectangular hole 45, a clamping plate 47 is fixedly connected to the bottom end of each pressure push shaft 44, and the clamping plate 47 is arranged in parallel with the corresponding fixing rod 41. A stabilizing plate 48 is fixedly connected to the outer end of each fixing box 42. A through hole 49 is opened on the top of each pressure push shaft 44. A concave cavity is opened in the middle of each friction wheel 40. A pull rope 50 is fixedly connected to the inside of each concave cavity. The other end of the pull rope 50 passes through the through hole 49 on the same side and is finally fixedly connected to the corresponding stabilizing plate 48. A buffer spring 51 is fixedly connected to each block 46. The other end of each buffer spring 51 is fixedly connected to the bottom end of the fixing box 42, and the buffer spring 51 is installed inside the rectangular hole 45. Under normal conditions, the pull rope 50 is in a taut state due to the force of the buffer spring 51.

[0054] When connecting the optical fiber, the personnel drives the three stabilizing frames and the friction wheels 40 on the same side to move away from each other, and the squeezing spring is compressed. Then the optical fiber line 13 is placed between the three friction wheels 40 on the same side, and then the optical fiber line 13 is installed inside the openings of the three notch blocks 33 on the same side. The optical fiber line 13 is set up in an up-and-down manner, and finally the optical fiber is fixed on the corresponding terminal 14. The squeezing spring is released, and the three friction wheels 40 on the same side will squeeze the outer side of the optical fiber line 13.

[0055] When the external optical fiber line 13 is suddenly pulled, the optical fiber line 13 will cause the three friction wheels 40 on the same side to rotate quickly and slide outward, and the pull rope 50 will be wound around the corresponding friction wheel 40, and the pull rope 50 will slide inside the perforation 49, thereby driving the pressure push shaft 44 to push the clamping plate 47 to approach the lower optical fiber line 13, and the state of the pull rope 50 gradually changes from the initial bending state to the straight state, and the buffer spring 51 is compressed, and the three clamping plates 47 on the same side will quickly clamp the optical fiber line 13, further improving the protection of the optical fiber line 13. Since the fixing rod 41 and the pressure push shaft 44 are inclined, the pressure push shaft 44 at this time pushes the clamping plate 47 to give the optical fiber line 13 a reverse thrust, so that the friction force of the clamping plate 47 on the optical fiber line 13 will also be greater, thereby preventing the optical fiber line 13 from being broken, and improving the stability of the connector;

[0056] When the external force disappears, due to the rebound force of the buffer spring 51, the block 46 is driven to slide gradually in the opposite direction with the pressure push shaft 44. At this time, the pull rope 50 will rotate with the corresponding friction wheel 40, and the three friction wheels 40 will gradually move the optical fiber line 13 into the protective tube 29 until all components are restored to their initial state.

[0057] like Figure 1 , Figure 7 As shown, a guide frame 52 is fixedly connected to the inner part of the outer end of each of the protective tubes 29, a wire hole is provided in the middle of the guide frame 52, an auxiliary spring 53 is fixedly connected to the inner end of each of the guide frames 52, and the other end of each of the auxiliary springs 53 is fixedly connected to the tripod 38, so that a certain distance is set between the tripod 38 and the guide frame 52, and the tripod 38 is slidably connected to the inner wall of the protective tube 29 left and right, and a placement opening 54 is respectively provided on each of the protective tubes 29, and a slide groove located in the placement opening 54 is provided on each of the protective tubes 29, and a slide rail is fixedly provided on each of the draw plates 55, and the slide rail is slidably installed in the slide groove, so that the draw plates 55 block the placement opening 54, and the outer end of each of the protective tubes 29 is detachably provided with a protective sleeve 56, and a threading opening is provided on the protective sleeve 56, and the extrusion strip 20 is a rubber block, which can increase the friction with the insulating layer of the optical fiber line 13;

[0058] The personnel remove the draw plate 55 from the inside of the placement opening 54, take the optical fiber line 13 and install it inside the threading opening and the wire hole, place the optical fiber line 13 between the three friction wheels 40 on the same side, and then install the optical fiber line 13 inside the openings of the three notch blocks 33 on the same side. The optical fiber line 13 is set up in a high and low manner, and finally the optical fiber is fixed on the corresponding terminal 14. The squeezing spring is released, and the three friction wheels 40 on the same side will squeeze the outer side of the optical fiber line 13, and then the slide rail is installed inside the slide groove, and the draw plate 55 blocks the placement opening 54;

[0059] When the external optical fiber 13 is pulled, the optical fiber 13 will slide along the threading port and the wire hole, and the optical fiber 13 will rotate rapidly with the three friction wheels 40 on the same side and slide out to the outside, and the pull rope 50 will be wound around the corresponding friction wheel 40, and the pull rope 50 will slide inside the perforation 49, thereby driving the pressure push shaft 44 to push the clamping plate 47 to approach the lower optical fiber 13, and the state of the pull rope 50 will gradually change from the initial bending state to the straight state, and the buffer spring 51 will be compressed, and the three clamping plates 47 on the same side will quickly clamp the optical fiber 13, so as to protect the optical fiber 13;

[0060] When the external optical fiber line 13 continues to be pulled, the optical fiber line 13 will move outward synchronously with the clamping plate 47, and the fixing box 42, the fixing rod 41, and the tripod 38 will slide outward synchronously. At this time, the tripod 38 applies pressure to the auxiliary spring 53, and the optical fiber line 13 will drive the notch block 33 to approach the center of the positioning semicircle 31. At this time, the telescopic rod 32 will drive the compression spring 34 to contract, so that the optical fiber line 13 can continue to extend outward for a part, thereby playing a buffering and protective role for the optical fiber line 13; due to the clamping effect of the clamping plate 47 on the optical fiber line 13, the clamping force point will move with the optical fiber line 13 to prevent the optical fiber line 13 from breaking when it is suddenly pulled by external force, which has the function of protecting the optical fiber line 13, and can also prevent the optical fiber from being damaged by external force, thereby ensuring the stability and reliability of optical signal transmission. When the external force disappears, each component returns to its initial state.
