Description

Technical Field

[0001] This utility model relates to the field of fiber optic switch technology, and more specifically, to a lightning-proof fiber optic switch. Background Technology

[0002] In the field of fiber optic communication, lightning-protected fiber optic switches are key equipment for ensuring stable network operation. Their lightning protection effect, maintenance convenience, and installation stability directly affect the reliability and operation and maintenance efficiency of the communication system. However, fiber optic switches on the market still have many technical defects in practical applications. These problems not only affect the safety performance of the equipment, but may also lead to communication interruption and equipment damage.

[0003] The primary problem is insufficient lightning protection. Existing fiber optic switch protection methods have significant defects: First, many devices only use simple enclosures for protection and lack dedicated lightning protection designs; second, the devices are directly exposed to the external environment and are susceptible to lightning strikes; third, there are no adequate grounding protection measures; in addition, lightning strikes may damage the device's circuitry; finally, this inadequate protection design not only reduces the safety of the equipment but also increases the risk of failure, seriously affecting the stable operation of the communication system.

[0004] More prominently, maintenance is inconvenient. Although most of the equipment adopts a structure in which the switch is mounted on an insulating block, there are serious problems: First, the installation process of fiber optic switches is complicated, requiring the assistance of various professional tools. The disassembly and assembly operations are numerous and time-consuming. The cumbersome maintenance operations increase labor costs. This cumbersome maintenance method not only reduces work efficiency but also prolongs the troubleshooting time, affecting the normal operation of the communication system.

[0005] The most critical issue is the poor installation stability. Although some devices have been improved to enable quick disassembly and assembly for convenient maintenance and cleaning of fiber optic switches, serious problems remain: First, the fixing structure is not strong enough. The operation of the equipment and the external environment will cause a certain degree of vibration, which can lead to the fixing structure loosening and falling off. This results in unstable installation or loss of fixing effect of the fiber optic switch. This structural defect not only affects the operational stability of the equipment, but may also cause equipment damage due to fixing failure, increasing the risk of equipment failure.

[0032] The lightning protection device includes a protective box 21, a box door 22, a down conductor 23, a grounding component 24, an insulating sleeve 25, a lightning protection strip 26, and an insulating block 27. The protective box 21 is located outside the fiber optic switch 1. The box door 22 is movably installed on one side of the protective box 21. The lightning protection strip 26 is detachably installed inside the top of the protective box 21. The bottom end of the down conductor 23 is connected to the grounding component 24, and the top end of the down conductor 23 is connected to the lightning protection strip 26. The insulating block 27 is fixedly installed inside the bottom of the protective box 21. The fiber optic switch 1 is installed above the insulating block 27. Multiple insulating sleeves 25 are detachably installed on both sides of the protective box 21.

[0033] Multiple heat dissipation slots 28 are provided on the door 22, and a protective cover 29 is provided on the outside of the heat dissipation slots 28. The protective cover 29 is fixedly installed on the outside of the door 22.

[0034] In this embodiment, when lightning strikes the outer shell of the protective box 21, the protective box 21, being made of metal, can effectively receive the lightning. The lightning is conducted through the protective box 21 to the lightning-absorbing strip 26 installed at the top inside. The lightning-absorbing strip 26 is specifically designed to receive and conduct lightning. It is connected to the top of the down conductor 23, which conducts the lightning energy downwards. The bottom end of the down conductor 23 is connected to the grounding component 24, which conducts the lightning energy to the ground, achieving safe discharge. During this process, the fiber optic switch 1 is installed above the insulating block 27 at the bottom inside the protective box 21. The insulating block 27 provides electrical isolation from the protective box 21, preventing lightning energy from being conducted to the equipment. Simultaneously, all necessary... All cables passing through the protective box 21 are protected by insulating sleeves 25 to prevent lightning from damaging the equipment through induction or conduction. The movable installation design of the box door 22 facilitates daily maintenance and repair. The entire lightning protection device forms a complete protection system. Through the "receive-conduct-ground" method, combined with electrical isolation measures, it achieves all-round lightning protection for the fiber optic switch 1, ensuring the safe and stable operation of the equipment in thunderstorm weather. The heat dissipation slots 28 ensure the heat dissipation effect of the fiber optic switch 1.

The insulating sleeve 25 is made of rubber.

[0035] Please see Figures 3-5 As a further implementation of the overall equipment: a limiting wheel 30 is provided on one side of the limiting block 13, and the limiting wheel 30 is engaged between the two corresponding positioning blocks 15.

[0036] A movable spring 31 is provided on the inner side of the connecting frame 3, and the other end of the movable spring 31 is connected to the outer wall of the connecting sleeve 2.

[0037] A support spring 32 is connected to one side of the limiting sleeve 12, and a thrust bearing 33 is detachably provided on one side of the rotating plate 10. The other end of the support spring 32 is connected to the thrust bearing 33.

[0038] A sliding block 34 is fixedly provided on the inner side of the limiting sleeve 12, and a sliding groove 35 is provided on the outer side of the connecting sleeve 2, and the sliding block 34 slides in the sliding groove 35.

[0039] Multiple limiting rails 36 are fixed on one side of the release sleeve 5, and a limiting groove 37 is opened on one side of the limiting block 13. The limiting groove 37 is adapted to the limiting rails 36.

[0040] More specifically, when maintenance and cleaning of the fiber optic switch 1 is required, first open the cabinet door 22, then rotate the rotating plate 10 in the forward direction. The rotating plate 10 drives the thrust bearing 33 and the rotating groove 11 installed on one side to rotate in the forward direction. The rotating plate 10 will also drive the rotating block 17 set on one side to rotate in the forward direction. Then the rotating block 17 will drive the arc-shaped rod 18 connected on one side to move along the arc-shaped hole 9 opened on the inner side of the fixed block 8. The rotating block 17 will cooperate with the fixed block 8 to squeeze the arc-shaped spring 19. When the arc-shaped spring 19 is squeezed to the limit, the rotating groove 11 will just rotate to the position corresponding to the positioning plate 14. Then push the limiting sleeve 12, so that the limiting sleeve 12 drives the limiting plate 16 and the three positioning plates 14 to gradually enter the rotating groove 11. The limiting sleeve 12 drives the sliding block 34 along the sliding groove 3. 5. Sliding, simultaneously the limiting sleeve 12 and the thrust bearing 33 cooperate to compress the support spring 32. When the support spring 32 is compressed to its limit, the positioning plate 14 closest to the limiting sleeve 12 just completely passes through the rotating groove 11 and moves to the other side of the rotating plate 10. Then the rotating plate 10 is released, and the arc spring 19 pushes the rotating block 17 to drive the arc rod 18 to rotate and reset along the arc hole 9. The rotating block 17 drives the rotating groove 11 to rotate and reset to a position that does not correspond to the positioning plate 14 through the rotating plate 10. At the same time, the rotating block 17 will drive the thrust bearing 33 installed on one side to rotate in the opposite direction through the rotating plate 10. Then the limiting plate 16 and the positioning plate 14 cooperate to limit the limiting sleeve 12 to one side of the rotating plate 10. Then the limiting sleeve 12 no longer limits the limiting wheel 30. Then the sleeve 5 is released by rotating in the forward direction. Release sleeve 5, via limit rail 36 and limit groove 37, drives limit block 13 and limit wheel 30 to rotate forward. Then, limit wheel 30 rolls out between two positioning blocks 15. Limit wheel 30 then drives limit block 13 to slide outward along limit rail 36 and limit groove 37, and limit block 13 drives tension spring 20 to stretch. At the same time, release sleeve 5 drives the variable diameter release groove 4 to rotate forward. Then, movable spring 31 pushes connecting frame 3 to move outward, so that the outer side of connecting frame 3 is always in close contact with the inner wall of release groove 4, and the other end of connecting frame 3 gradually slides out of connecting groove 6. Then, connecting sleeve 2 is pulled upward to remove it. Then, follow the above steps to remove other connecting sleeves 2, thus achieving convenient access to fiber optic switch 1. After maintenance and cleaning of fiber optic switch 1, place it back on insulating block 27, ensuring connecting rod 7 passes through the pre-drilled mounting hole on fiber optic switch 1. Then, re-attach connecting sleeve 2 to the outside of connecting rod 7. Next, rotate release sleeve 5 in the reverse direction, causing release sleeve 5 to rotate in the opposite direction via limiting rail 36 and limiting groove 37, driving limiting block 13 and limiting wheel 30. Simultaneously, release sleeve 5 will cause the inner release groove 4 to rotate in the opposite direction, pressing the connecting frame 3 inward. This causes the connecting frame 3 to compress the movable spring 31, while the other end of the connecting frame 3 gradually inserts into the connecting groove 6. When the connecting frame 3 is fully inserted into the connecting groove 6, limiting block 13 and limiting wheel 30 are positioned between the two original positioning blocks 15.Then, the tension spring 20 pulls the limiting block 13 and the limiting wheel 30 to slide inward along the limiting rail 36 and the limiting groove 37. Then, the rotating plate 10 rotates forward again, causing the rotating plate 10 to drive the rotating groove 11 and the thrust bearing 33 to rotate forward again. The rotating plate 10 will also drive the rotating block 17 to rotate forward again. Then, the rotating block 17 will drive the arc rod 18 to move along the arc groove and cooperate with the fixed block 8 to press the arc spring 19. When the rotating groove 11 rotates to the position corresponding to the positioning plate 14 again, the support spring 32 pushes the limiting sleeve 12 to drive the sliding block 34 to slide and reset along the sliding groove 35. Then, the limiting sleeve 12 will drive the three positioning plates 14 to slide and reset through the limiting plate 16. When the support spring 32 is fully reset, the other two positioning plates 14 are exactly on both sides of the rotating plate 10. Then, the rotating plate 10 is released. The arc spring 19 pushes the rotating block 17 to rotate and reset, and the rotating block 17 drives the arc rod 18 to rotate and reset along the arc hole 9. Then, the rotating block 17 will again drive the rotating groove 11 to rotate and reset to a position that does not correspond to the positioning plate 14 and the limiting plate 16 through the rotating plate 10. Then, the limiting plate 16 and the two positioning plates 14 cooperate to support and limit the limiting sleeve 12. With the limiting of the sliding block 34 and the sliding groove 35, the limiting sleeve 12 will not slide. Then, the inner wall of the limiting sleeve 12 limits the outer side of the limiting wheel 30, so that the limiting wheel 30 and the limiting block 13 will not slide outward, thereby realizing the limiting of the release sleeve 5, ensuring the stability of the installation structure, and ensuring the stable use of the fiber optic switch 1. Then, the box door 22 is closed, and the box door 22 is locked to one side of the protective box 21 by the external lock.

[0041] In summary, during the use or operation of the overall equipment: when lightning strikes the outer shell of the protective box 21, because the protective box 21 is made of metal, it can effectively receive lightning. The lightning is conducted through the protective box 21 to the lightning-absorbing strip 26 installed at the top inside. The lightning-absorbing strip 26 is specifically designed to receive and conduct lightning. It is connected to the top of the down conductor 23, which conducts the lightning energy downwards. The bottom end of the down conductor 23 is connected to the grounding component 24, which conducts the lightning energy to the ground, achieving safe discharge. During this process, the fiber optic switch 1 is installed above the insulating block 27 at the bottom inside the protective box 21. The insulating block 27 provides electrical isolation from the protective box 21, preventing lightning energy from being conducted to the equipment. At the same time, all cables that need to pass through the protective box 21 are protected by the insulating sleeve 25 to prevent lightning from damaging the equipment through induction or conduction. The movable installation design of the box door 22 facilitates daily maintenance and repair. The entire lightning protection device forms a complete protection system. Through the "receive-conduct-ground" method, combined with electrical isolation measures, it achieves all-round lightning protection for the fiber optic switch 1, ensuring the safe and stable operation of the equipment in thunderstorm weather. The setting of the heat dissipation slot 28 ensures the heat dissipation effect of the fiber optic switch 1. The setting of the protective cover 29 can prevent external rainwater from entering the interior of the protective box 21 from the heat dissipation slot 28, thus ensuring the protection effect. In addition, the insulating sleeve 25 is made of rubber.

[0042] When maintenance and cleaning of the fiber optic switch 1 are required, first open the cabinet door 22, then rotate the rotating plate 10 clockwise. The rotating plate 10 drives the thrust bearing 33 and the rotating groove 11 installed on one side to rotate clockwise, and the rotating plate 10 will drive the rotating block 17 set on one side to rotate clockwise. Then the rotating block 17 will drive the arc-shaped rod 18 connected on one side to move along the arc-shaped hole 9 opened on the inner side of the fixed block 8, and the rotating block 17 will cooperate with the fixed block 8 to compress the arc-shaped spring 19. When the arc-shaped spring 19 is compressed to its limit, the rotating groove 11 will just rotate to the position corresponding to the positioning plate 14, and then push the limiting sleeve 12, so that the limiting sleeve 12 drives the limiting plate 16 and the three positioning plates 14 to gradually pass into the rotating groove 11, and the limiting sleeve 12 drives the sliding block 34 to slide along the sliding groove 35. Simultaneously, the limiting sleeve 12 and the thrust bearing 33 cooperate to compress the support spring 32. When the support spring 32 is compressed to its limit, the positioning plate 14 closest to the limiting sleeve 12 just passes through the rotating groove 11 and moves to the other side of the rotating plate 10. Then the rotating plate 10 is released, and the arc spring 19 pushes the rotating block 17 to drive the arc rod 18 to rotate and reset along the arc hole 9. The rotating block 17 drives the rotating groove 11 to rotate and reset to a position that does not correspond to the positioning plate 14 through the rotating plate 10. At the same time, the rotating block 17 will drive the thrust bearing 33 installed on one side to rotate in the opposite direction through the rotating plate 10. Then the limiting plate 16 and the positioning plate 14 cooperate to limit the limiting sleeve 12 to one side of the rotating plate 10. Then the limiting sleeve 12 no longer limits the limiting wheel 30. Then the sleeve 5 is rotated in the forward direction to release the sleeve 5. The limiting rail 36 and limiting groove 37 drive the limiting block 13 and limiting wheel 30 to rotate forward. Then, the limiting wheel 30 rolls out between the two positioning blocks 15. The limiting wheel 30 then drives the limiting block 13 to slide outward along the limiting rail 36 and limiting groove 37. The limiting block 13 drives the tension spring 20 to stretch. At the same time, the release sleeve 5 drives the variable diameter release groove 4 to rotate forward. Then, the movable spring 31 pushes the connecting frame 3 to move outward, so that the outer side of the connecting frame 3 is always in close contact with the inner wall of the release groove 4. The other end of the connecting frame 3 will gradually slide out of the connecting groove 6. Then, the connecting sleeve 2 is pulled upward to remove it. Then, the other connecting sleeves 2 are removed by following the above steps. This allows for the convenient removal of the fiber optic switch 1. After the maintenance and cleaning of fiber optic switch 1 is completed, fiber optic switch 1 is placed back on insulating block 27, and connecting rod 7 is passed through the pre-drilled mounting hole on fiber optic switch 1. Then, connecting sleeve 2 is re-attached to the outside of connecting rod 7. Then, release sleeve 5 is rotated in the reverse direction, causing release sleeve 5 to drive limit block 13 and limit wheel 30 to rotate in the reverse direction through limit rail 36 and limit groove 37. At the same time, release sleeve 5 will drive the release groove 4 opened on the inner side to rotate in the reverse direction. Then, the inner wall of release groove 4 presses connecting frame 3 inward, so that connecting frame 3 compresses movable spring 31. At the same time, the other end of connecting frame 3 is gradually inserted into connecting groove 6. When connecting frame 3 is fully inserted into connecting groove 6, limit block 13 and limit wheel 30 are just moved between the two original positioning blocks 15.Then, the tension spring 20 pulls the limiting block 13 and the limiting wheel 30 to slide inward along the limiting rail 36 and the limiting groove 37. Then, the rotating plate 10 rotates forward again, causing the rotating plate 10 to drive the rotating groove 11 and the thrust bearing 33 to rotate forward again. The rotating plate 10 will also drive the rotating block 17 to rotate forward again. Then, the rotating block 17 will drive the arc rod 18 to move along the arc groove and cooperate with the fixed block 8 to press the arc spring 19. When the rotating groove 11 rotates to the position corresponding to the positioning plate 14 again, the support spring 32 pushes the limiting sleeve 12 to drive the sliding block 34 to slide and reset along the sliding groove 35. Then, the limiting sleeve 12 will drive the three positioning plates 14 to slide and reset through the limiting plate 16. When the support spring 32 is fully reset, the other two positioning plates 14 are exactly on both sides of the rotating plate 10. Then, the rotating plate 10 is released. The arc spring 19 pushes the rotating block 17 to rotate and reset, and the rotating block 17 drives the arc rod 18 to rotate and reset along the arc hole 9. Then, the rotating block 17 will again drive the rotating groove 11 to rotate and reset to a position that does not correspond to the positioning plate 14 and the limiting plate 16 through the rotating plate 10. Then, the limiting plate 16 and the two positioning plates 14 cooperate to support and limit the limiting sleeve 12. With the limiting of the sliding block 34 and the sliding groove 35, the limiting sleeve 12 will not slide.
