Description

Technical Field

[0001] This utility model relates to the field of pressure protection technology for fiber optic connectors, specifically a pressure protection structure for fiber optic connectors. Background Technology

[0002] Fiber optic connectors are devices that provide detachable (movable) connections between optical fibers. They precisely align the two end faces of the fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber, and to minimize the impact on the system caused by their intervention in the optical link. These are the fundamental requirements of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] Existing fiber optic connector pressure protection structures are partially buried underground. These underground structures may be subjected to pressure from multiple factors. When the pressure on the fiber optic connector pressure protection structure exceeds the threshold and damages the fiber optic connector, it is difficult to locate the specific location of the fiber optic connector in a timely and accurate manner. Furthermore, once the fiber optic connector is located, it is difficult to completely open the pressure protection structure for repair and replacement. Therefore, we need to propose a pressure protection structure for fiber optic connectors. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a pressure-resistant protective structure for fiber optic connectors, including a protective cover body and a fiber optic connector 2. The fiber optic connector 2 is installed inside the protective cover body. Two identical buffer assemblies for pressure-resistant buffering of the fiber optic connector 2 are installed between the fiber optic connector 2 and the upper and lower surfaces inside the protective cover body. The buffer assembly of the lower cover 17 includes a base plate 18. The fiber optic connector 2 is attached to one side of the base plate 18. Grooves are formed at both ends of the other side of the base plate 18. Supporting pads 14 are connected to both sides of the two sets of grooves. A first spring 15 is connected to one side of the supporting pad 14 and inside the groove. A buffer pad 16 is connected to the other side of the first spring 15. A roller 13 is installed between the two sets of buffer pads 16.

[0027] Roller 13 is tactilely connected to connecting block 12. A leaf spring 11 is connected to the other end of connecting block 12. A support column 10 is connected to the side of leaf spring 11 furthest from connecting block 12 and located in the center area. A rubber pad 9 is connected to the other end of support column 10. The other side of rubber pad 9 is fixedly connected to the center area of ​​the lower surface inside the lower cover 17. External pressure is applied to the protective cover body, and this pressure is transmitted from rubber pad 9 to leaf spring 11 via support column 10. Leaf spring 11 deforms to provide cushioning. The deformation of leaf spring 11 causes connecting block 12 to roll roller 13, providing cushioning. Roller 13 presses against buffer pad 16 in the groove of base plate 18, causing first spring 15 to deform and provide cushioning. Support pad 14 supports first spring 15, allowing roller 13 to return to its original position after moving back and forth in the groove.

[0028] Furthermore, four sets of sleeves 24 are fixedly connected to the four corners of the base plate 18 away from the fiber optic connector 2. A third spring 26 is installed at one end of the sleeve 24, and a damping particle 25 is fixedly installed at the other end of the sleeve 24. A cylinder 23 is slidably connected inside the sleeve 24. One end of the cylinder 23 is in contact with the third spring 26, and the other end of the cylinder 23 is fixedly connected to the lower surface of the lower cover 17. Four sets of support plates 21 are fixedly installed at the four corners of the lower cover 17. All four sets of support plates 21 are located above the base plate 18 and in contact with the support plate 21 of the upper cover 1. A second spring 19 is fixedly connected between the support plate 21 and the base plate 18. The external pressure on the protective cover body is buffered by the cylinder 23 pressing the third spring 26 inside the sleeve 24. After the third spring 26 deforms and rebounds, the damping particles 25 can buffer the rebound of the third spring 26. The second spring 19 can buffer the compression of the sleeve 24 and the steel leaf spring 11 on the base plate 18. The support plate 21 can support the deformation of the second spring 19.

[0029] Furthermore, the protective cover body includes an upper cover 1 and a lower cover 17. Two identical opening and closing components for opening and closing the protective cover body are installed between the upper cover 1 and the lower cover 17. Two sets of grooves are provided between the upper cover 1 and the lower cover 17. The two sets of opening and closing components are located inside the two sets of grooves. The opening and closing components include a first guide rail 5 and a second guide rail 6. The length of the first guide rail 5 is half that of the second guide rail 6. The first guide rail 5 is installed in the groove of the lower cover 17, and the second guide rail 6 is installed in the groove of the upper cover 1. A slider 3 is slidably connected between the first guide rail 5 and the second guide rail 6. The slider 3 has the same length as the first guide rail 5. Four sets of limiting blocks 20 are installed on the upper end of the lower cover 17 and on both sides of the opening and closing components. A limiting groove 22 is provided at the lower end of the upper cover 1, which is directly opposite to the limiting blocks 20.

[0030] By setting grooves, the internal opening and closing components can be protected. The first guide rail 5 and the second guide rail 6 allow the slider 3 to slide horizontally within the grooves. By adjusting the lengths of the first guide rail 5, the second guide rail 6, and the slider 3, the slider 3 can be changed from sliding simultaneously with both guide rails 5 and 6 to sliding only with the second guide rail 6. By connecting the first guide rail 5 and the second guide rail 6 to the grooves in the lower cover 17 and the upper cover 1 respectively, the slider 3 can complete the opening and closing of the opening and closing components during sliding. The lower cover 17 has a limiting block 20, and the upper cover 1 has a corresponding limiting groove 22, which facilitates the merging of the protective cover body and increases overall rigidity.

[0031] In addition, the buffer assembly includes a base plate 18. A pressure sensor 7 is installed above the base plate 18 inside the upper cover 1. A positioner 8 is installed on one side of the fiber optic connector 2. Both the pressure sensor 7 and the positioner 8 are located inside the protective cover body. A wire 28 is connected to the upper part of the upper cover 1. One end of the wire 28 is connected to a controller 29. The pressure sensor 7 and the positioner 8 are electrically connected to the controller 29 through the wire 28. One end of the pressure sensor 7 is installed above the base plate 18 inside the upper cover 1. The other end of the pressure sensor 7 is connected to a fourth spring 27. The other end of the fourth spring 27 is connected to a steel leaf spring 11. The positioner 8 is installed on one side inside the lower cover 17. There is a gap between the positioner 8 and the buffer assembly. Fiber optic cables 30 are connected to both ends of the fiber optic connector 2. Rubber sleeves 4 are fitted on both ends of the fiber optic cables 30 outside the protective cover body. The rubber sleeves 4 include an upper half and a lower half, which are fixedly connected to the upper cover 1 and the lower cover 17, respectively.

[0032] Pressure is transmitted to the fourth spring 27 through the steel leaf spring 11. The pressure sensor 7 can detect the pressure on the protective structure by the pressure generated by the force of the fourth spring 27. The data detected by the pressure sensor 7 is transmitted to the controller 29 through the wire 28. The controller 29 transmits the data to the worker in real time. By setting the positioner 8, the position signal transmitted by the positioner 8 is transmitted to the controller 29 through the wire 28. When the pressure sensor 7 detects that the pressure on the protective cover body exceeds the threshold, the fiber optic connector 2 can be accurately located.

[0033] The rubber sleeve 4 protects the small section of optical fiber of the fiber optic connector 2 located outside the protective cover, providing support and protection for this section. The rubber sleeve 4 divides the fiber into two parts, communicating with the upper cover 1 and the lower cover 17 respectively. Both sides of the upper cover 1 and the lower cover 17 have holes adapted to the optical fiber line 30, allowing the optical fiber line 30 to pass through the rubber sleeve 4 and enter the interior of the upper cover 1 and the lower cover 17 to connect with the fiber optic connector 2. Sealant is applied between the optical fiber line 30 and the holes to prevent water ingress when the protective cover is buried underground. The conductor 28 is covered with corrosion-resistant and waterproof insulating material. If the fiber optic connector 2 is buried underground in actual use, the end of the conductor 28 furthest from the connector can extend to the ground and connect to the controller 29. The controller 29 receives signals from the underground pressure sensor 7 and the locator 8, facilitating accurate fault location. In this embodiment, structures made of metal materials such as the first spring 15, the second spring 19, the third spring 26, the fourth spring 27, and the leaf spring 11 all need to undergo anti-corrosion and anti-rust treatment before actual installation and use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
