Technical Field

[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 so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the impact on the system caused by its involvement in the optical link is minimized. This is the basic requirement of a fiber optic connector. A fiber optic connector ensures the maximum transmission of optical signals by precisely aligning and connecting the ends of the optical fibers.

[0003] With the rapid development of fiber optic network communication systems, the use of various types of fiber optic communication equipment has gradually increased. In order to meet the needs of building fiber optic communication networks, it is necessary to extend the fiber optic line through connectors to meet the needs of outdoor installation. However, most of the existing fiber optic connectors are in relatively harsh outdoor environments. The contact ends of the two connectors are easily infiltrated by wind, sand and dust. Traditional fiber optic connectors have low resistance to dust and are easily polluted by the environment, causing failures, which seriously affects the stability and reliability of the operation of the fiber optic communication system. The structural stability of traditional fiber optic connectors is relatively insufficient. When the fiber optic line is pulled by external force, the connector and the fiber optic line are easily detached, affecting the transmission effect of the fiber optic data.

Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] A dust-proof device for an optical fiber active connector with multiple seals, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, it includes a left connector 1 and a right connector 2. The left connector 1 and the right connector 2 are tubular structures and have the same specifications. A left base 3 is coaxially fixedly installed on the right end of the left connector 1, and a right base 4 is coaxially fixedly installed on the left end of the right connector 2. The left base 3 and the right base 4 have the same specifications and their outer diameters are larger than the outer diameters of the left connector 1 and the right connector 2. A left fixing ring 5 is coaxially fixedly installed on the right end of the left base 3. The left fixing ring 5 and the left connector 1 are arranged to be through-connected on the left and right. Two left dividing blocks 6 are evenly fixedly installed on the outer end of the left fixing ring 5. The two left dividing blocks 6 are symmetrically arranged. A front installation cavity is formed between the front sides of the two left dividing blocks 6 and the outer wall of the left fixing ring 5, and a rear installation cavity is formed between the rear sides of the two left dividing blocks 6 and the outer wall of the left fixing ring 5. A semicircular sealing shell 7 is fixedly installed inside the front installation cavity and the rear installation cavity respectively.

[0037] The two sealing shells 7 are respectively provided with left arc-shaped cavities with openings facing right, and a semicircular sealing plate 8 is respectively installed in each left arc-shaped cavity for sliding left and right. A right fixing ring 9 is coaxially fixedly installed on the left end of the right base 4, and the right fixing ring 9 and the right connector 2 are arranged to be through-connected left and right. Two right dividing blocks 10 are evenly fixedly installed on the outer end of the right fixing ring 9, and the two right dividing blocks 10 are symmetrically arranged with each other. A front positioning cavity is formed between the front sides of the two right dividing blocks 10 and the outer wall of the right fixing ring 9, and a rear positioning cavity is formed between the rear sides of the two right dividing blocks 10 and the outer wall of the right fixing ring 9. The positioning cavity, the interior of the front positioning cavity and the rear positioning cavity are respectively fixed with a semicircular structure plug-in shell 11, and the interiors of the two plug-in shells 11 are respectively provided with a semicircular structure sealing port with an opening facing left, and the sealing port is just matched with the sealing plate 8. A locking assembly is arranged between the left connector 1 and the right connector 2, and the locking assembly is used for the locking function between the left connector 1 and the right connector 2. The interiors of the two left dividing blocks 6 are respectively provided with a driving assembly, and the interiors of the left connector 1 and the right connector 2 are respectively provided with an optical fiber line 12. (The position and direction of all components in this embodiment are shown in Figure 1.) Figure 1 , Figure 2 , Figure 3 , Figure 4 for reference);

[0038] During use, personnel install the optical fiber line 12 inside the left connector 1 and the right connector 2 respectively, and the exposed end of the optical fiber line 12 is set inside the left fixing ring 5 and the right fixing ring 9, then gradually bring the left connector 1 and the right connector 2 closer until the left fixing ring 5 and the right fixing ring 9 are in contact, and the fiber cores of the two optical fiber lines 12 are completely in contact, and the driving component pushes the two sealing plates 8 to be fully inserted into the sealing openings of the corresponding plug-in shells 11, and then the locking component is used to lock the left connector 1 and the right connector 2. At this time, the sealing plate 8 can seal the contact end between the left fixing ring 5 and the right fixing ring 9 to prevent dust from entering the connector from the contact end of the left fixing ring 5 and the right fixing ring 9, affecting the use of the optical fiber line 12, and also preventing the optical fiber line 12 from being polluted by the external environment and damaged by external forces, preventing network slowdown or failure, thereby extending the service life of the connector, ensuring the quality of signal transmission, reducing signal attenuation and interference caused by dust, and thus improving the stability and security of the network, thereby reducing maintenance costs and troubleshooting time.

[0039] like Figure 4 , Fig.13As shown, a left inserting block 13 is fixedly installed inside the right end of the left fixing ring 5, and the right end of the left inserting block 13 protrudes out of the left fixing ring 5. A left fixing frame 14 is fixedly installed inside the left end of the left inserting block 13, and left wire holes that pass through the left and right are respectively opened on the left inserting block 13 and the left fixing frame 14. A right inserting block 15 is fixedly installed inside the left end of the right fixing ring 9, and the left end of the right inserting block 15 is set lower than the right fixing ring 9. This facilitates the insertion of the left inserting block 13 into the right fixing ring 9 and improves the stability of the connector. A right fixing frame 53 is fixedly installed inside the right end of the right inserting block 15, and right wire holes that pass through the left and right are respectively opened on the right inserting block 15 and the right fixing frame 53. The left wire hole and the right wire hole are concentrically arranged. The right end of the left optical fiber line 12 is installed in the left wire hole, and the left end of the right optical fiber line 12 is installed in the right wire hole, which can play a good guiding and fixing role for the optical fiber line 12.

[0040] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.11 , Fig.12 As shown, the locking assembly includes an insert plate 16, and the insert plates 16 are fixedly installed on the right ends of the two left split blocks 6, and the positioning shells 17 are fixedly installed on the outer ends of the two insert plates 16 away from each other. Reset card plates 18 are slidably installed inside the two positioning shells 17, and the reset card plates 18 can move away from or approach the center of the left connector 1 along the positioning shells 17. Pull blocks 19 are fixedly installed on the right ends of the two reset card plates 18, and reset springs 20 are fixedly installed on the two pull blocks 19. The other end of each reset spring 20 The ends are fixedly connected to the corresponding positioning shells 17, and the inner ends of the two reset card plates 18 are respectively fixedly installed with positioning rods 21, and the inner ends of the positioning rods 21 are round. The two right split blocks 10 are respectively provided with sliding openings 22, and the insides of the two sliding openings 22 are respectively provided with locking blocks 23 that can slide left and right. The inner walls of the sliding openings 22 are provided with sliding grooves, and the locking blocks 23 are fixedly installed with sliders, which are slidably installed in the corresponding sliding grooves. The outer ends of the two locking blocks 23 are respectively provided with positioning holes 24, and the left end of the locking block 23 is an arc surface;

[0041] When in use, the personnel gradually bring the right connector 2 closer to the left connector 1, and the two plug plates 16 are respectively inserted into the corresponding sliding openings 22 until the right fixing ring 9 is completely in contact with the left fixing ring 5. The inner surfaces of the two plug plates 16 are in contact with the outer surfaces of the corresponding locking blocks 23, and then the two locking blocks 23 are driven to move to the left, and the arc surface on the locking block 23 is in contact with the circular surface, and slides outward against the positioning rod 21. At this time, the two positioning rods 21 move away from the corresponding reset card plate 18 and the pull block 19 outward, and the reset spring 20 is in the state of being pressed. In the stretched state, when the two locking blocks 23 slide to the positioning holes 24 along the corresponding positioning rods 21, due to the contraction force of the return spring 20, the two positioning rods 21 are quickly inserted into the corresponding positioning holes 24, thereby realizing the locking state between the left connector 1 and the right connector 2, ensuring that the optical fiber connector can maintain a firm connection under the external environment, reducing loosening or falling off due to factors such as vibration and pulling, thereby improving the stability and reliability of the connector, ensuring stable signal transmission, and reducing network interruption problems caused by connection problems;

[0042] When the right connector 2 and the left connector 1 need to be separated, the two pull blocks 19 are pulled away from each other at the same time, the reset spring 20 is stretched, and the two reset card plates 18 are completely disengaged from the corresponding positioning holes 24 with the positioning rods 21, and the right connector 2 and the left connector 1 are driven to separate, thereby realizing the connector installation and separation work and improving work efficiency.

[0043] like Figure 8 , Fig. 9 , Fig.11 , Fig.12 , Fig.13 As shown, the driving assembly includes a driving gear ring 25, an annular cavity 26 is opened on the outer end of the right base 4, and the opening of the annular cavity 26 is set outward. The driving gear ring 25 is rotatably installed inside the annular cavity 26, and two driving gears 27 meshing with the driving gear ring 25 are rotatably installed inside the annular cavity 26. The two driving gears 27 are respectively threaded with driving screws 28. The right ends of the driving screws 28 slide left and right and penetrate the right base 4 respectively. The left ends of the driving screws 28 are fixedly installed on the corresponding locking blocks 23. The left ends of the two locking blocks 23 are respectively fixedly installed with push rods 29, and the insides of the two left split blocks 6 are respectively provided with pushing assemblies.

[0044] like Figure 6 , Figure 7 , Fig.10 , Fig.12 , Fig.13As shown, the pushing assembly includes a pushing plate 30, an insertion hole 31 is respectively opened on the right end of the two left dividing blocks 6, and the pushing plates 30 are respectively installed in the inside of the two insertion holes 31 for sliding left and right, and the left ends of the two pushing plates 30 are respectively fixedly installed with pushing racks 32, and the two ends of the pushing racks 32 are respectively provided with teeth, and the left ends of the two pushing racks 32 are respectively fixedly installed with pressure springs 33, and the other end of the pressure spring 33 is fixedly installed on the left base 3, and the two ends of each left dividing block 6 are respectively rotatably installed with a self-rotating gear 34 meshing with the corresponding pushing rack 32, and the two ends of the sealing shell 7 are respectively opened with through openings, and the two ends of the sealing plate 8 are respectively fixedly provided with moving racks, and the self-rotating gear 34 passes through the through opening and is meshed and connected with the corresponding self-rotating gear 34;

[0045] When the right fixing ring 9 is completely in contact with the left fixing ring 5, the rotating driving gear ring 25 meshes with the two driving gears 27 to rotate. Since one end of the driving screw rod 28 is fixedly mounted on the locking block 23, the locking block 23 can only slide left and right. The two driving gears 27 rotate with the corresponding driving screw rods 28, and the driving screw rods 28 push the corresponding locking block 23 and the push rod 29 to move synchronously to the left. The arc surface on the locking block 23 contacts the circular surface and pushes the positioning plug rod 21 to slide outward. At this time, the two positioning plug rods 21 move away from the corresponding reset card plate 18 and the pull block 19 outward until the positioning plug rod 21 is fully inserted into the corresponding positioning hole 24.

[0046] At the same time, the push rod 29 pushes the corresponding push plate 30 to move to the left, and the pressure spring 33 is continuously compressed, pushing the rack 32 to engage with the corresponding two self-rotating gears 34 to rotate, and the self-rotating gear 34 engages with the corresponding moving rack to move to the right, driving the two sealing plates 8 to be quickly inserted into the sealing port of the corresponding plug-in shell 11, thereby realizing the sealing function between the left fixing ring 5 and the right fixing ring 9, which can prevent external dust from entering the contact position of the two optical fiber lines 12, improve the stability and safety of the network, and reduce the occurrence of failure rates.

[0047] like Figure 4 , Figure 6As shown, a left sliding plate 35 located on the left side of the left insertion block 13 is installed inside the left connector 1 for sliding left and right. Three first connecting rods 36 are evenly installed on the right end of the left sliding plate 35 for rotating evenly. Three second connecting rods 37 are evenly installed on the left end of the left insertion block 13 for rotating evenly. The three first connecting rods 36 and the three second connecting rods 37 are symmetrically arranged. The right end of each first connecting rod 36 is rotationally connected to the left end of the corresponding second connecting rod 37. The hinged end of the first connecting rod 36 and the second connecting rod 37 is rotationally installed with a left extrusion block 38 made of rubber material. The inner end of the left extrusion block 38 is a circular block with friction grooves. A left guide rod 39 is fixedly installed on each of the left extrusion blocks 38. Three vertical left sliding holes are opened at the right end of the left sliding disk 35. The other end of each left guide rod 39 is slidably installed in the corresponding left sliding hole. The left guide rod 39 can slide left and right inside the left sliding hole and slide up and down in the left sliding hole. A left extrusion ring 40 is coaxially fixedly installed on the left end of the left sliding disk 35. Under normal conditions, the outer ends of the first connecting rod 36 and the second connecting rod 37 are bent at an included angle.

[0048] like Figure 4 , Figure 8 , Fig. 9 As shown, the right connector 2 is internally slidably installed with a right sliding plate 41 located on the right side of the right insertion block 15, and three third connecting rods 42 are evenly rotatably installed on the left end of the right sliding plate 41, and three fourth connecting rods 43 are evenly rotatably installed on the right end of the right insertion block 15. The three third connecting rods 42 and the three fourth connecting rods 43 are symmetrically arranged, and the left end of each third connecting rod 42 is rotatably connected to the right end of the corresponding fourth connecting rod 43. The hinged end of the third connecting rod 42 and the fourth connecting rod 43 is rotatably installed with a right extrusion block 44 made of rubber material, and the right extrusion block 4 4 is a circular block with friction lines. Three right sliding holes are provided on the left end of the right sliding disk 41. A right guide rod 45 located in the right sliding hole is fixedly installed on each of the right extrusion blocks 44. The right guide rod 45 can slide left and right and up and down inside the right sliding hole. A right extrusion ring 46 is coaxially fixedly installed on the right end of the right sliding disk 41. A left sealing ring 47 is provided with threaded holes that penetrate left and right. A left sealing block 48 is threadedly installed in the thread. Under normal conditions, the outer ends of the third connecting rod 42 and the fourth connecting rod 43 are bent at an included angle.

[0049] like Figure 1 , Figure 2As shown, a left closed ring 47 is threadedly installed in the left end hole of the left connector 1, a left sealing block 48 is threadedly installed in the left end hole of the left closed ring 47, a right closed ring 49 is threadedly installed in the right end hole of the right connector 2, a threaded hole extending from left to right is provided at the right end of the right closed ring 49, a right sealing block 50 is threadedly installed in the thread, placement holes extending from left to right are respectively provided on the left sealing block 48 and the right sealing block 50, a sealing layer is fixedly provided on the inner wall of the placement hole, the sealing layer is such as sealing cotton or other suitable objects.

[0050] like Figure 6 , Fig. 9 As shown, a left top pressure spring 51 is fixedly installed on the right end of the left sliding plate 35, and the other end of the left top pressure spring 51 is fixedly connected to the left insertion block 13, and a right top pressure spring 52 is fixedly installed on the left end of the right sliding plate 41, and the other end of the right top pressure spring 52 is fixedly connected to the right insertion block 15;

[0051] When in use, the left sealing block 48 is threadedly installed on the left closed ring 47, and the right sealing block 50 is threadedly installed on the right closed ring 49. Then, the optical fiber line 12 is passed through the respective placement holes, and the sealing layer contacts the outer wall of the optical fiber line 12 to block dust. The right end of the left optical fiber line 12 is passed through the left line hole on the left insertion block 13 and the left fixing frame 14, and the left end of the right optical fiber line 12 is passed through the right line hole on the right insertion block 15 and the right fixing frame 53, until the two optical fiber lines 12 are completely installed.

[0052] The personnel threadably install the left closed ring 47 inside the left end of the left connector 1, and at the same time, the right end face of the left closed ring 47 is in sliding contact with the left end face of the left extrusion ring 40. As the left closed ring 47 continuously moves to the right, the left sliding plate 35 pushes the three first connecting rods 36 and the second connecting rods 37 to gradually approach the optical fiber line 12, and the angle between the outer ends of the first connecting rod 36 and the second connecting rod 37 gradually decreases. The left guide rod 39 slides freely along the left sliding hole. At this time, the left extrusion block 38 can only move straight back and forth, and the left top pressure spring 51 is gradually compressed until the three left extrusion blocks 38 clamp the outer insulation layer of the optical fiber line 12. Since the left extrusion block 38 is made of rubber, it will not cause damage to the optical fiber line 12. When the exposed optical fiber line 12 is pulled, the three left extrusion blocks 38 clamp the optical fiber line 12, which will not cause the optical fiber line 12 to detach from the connector, thereby improving the stability of transmission.

[0053] Then the personnel threadedly install the right closed ring 49 inside the right end of the right connector 2, and the left end face of the right closed ring 49 slides in contact with the right end face of the right extrusion ring 46. As the right closed ring 49 continues to move to the left, the three right sliding plates 41 push the third connecting rods 42 and the three fourth connecting rods 43 gradually approach the optical fiber line 12, and the outer end angle of the third connecting rod 42 and the fourth connecting rod 43 gradually decreases. The right guide rod 45 slides freely along the right sliding hole. At this time, the right extrusion block 44 moves straight back and forth, and the right top pressure spring 52 is gradually compressed. Until the three right squeezing blocks 44 clamp the outer insulation layer of the optical fiber 12. Since the right squeezing block 44 is made of rubber, it will not damage the optical fiber 12. When the exposed optical fiber 12 is pulled, the three right squeezing blocks 44 clamp the optical fiber 12, so that the optical fiber 12 will not be separated, thereby improving the stability and safety of transmission, and effectively preventing the optical fiber 12 from being broken or damaged when being pulled by external force, thereby protecting the integrity of the optical fiber and reducing maintenance costs and time;

[0054] Since the left end of the left connector 1 is provided with a left closing ring 47 and a left sealing block 48, and the right end of the right connector 2 is provided with a right closing ring 49 and a right sealing block 50, multiple sealing effects of the connector are achieved, preventing external dust from entering the interior of the connector and improving the stability of the connector.
