Technical Field
[0001] This application relates to the field of routine maintenance of optical splitters, and in particular to a PLC optical splitter that is easy to maintain. Background Technology
[0002] A PLC optical splitter, short for planar waveguide optical splitter, is an integrated waveguide optical power distribution device based on a quartz substrate. It is primarily used in optical network systems to couple, branch, and distribute optical signals. This type of splitter connects central office and terminal equipment in passive optical networks and performs optical signal splitting.
[0003] In related technologies, PLC optical splitters continuously generate heat during operation, necessitating heat dissipation after prolonged use to ensure stable internal heat levels. Specifically, optical splitters often have ventilation holes to allow heat to escape. While this traditional method provides some cooling, it also allows dust from the outside air to easily enter the splitter. Due to the delicate structure of optical splitters, dust inside can negatively impact performance, such as increasing insertion loss and reducing beam uniformity. Therefore, maintaining stable heat dissipation while keeping the equipment clean is crucial for ensuring long-term stable operation. Summary of the Invention
[0004] This application provides a PLC optical splitter that is easy to maintain. The purpose is to optimize the heat dissipation process of the optical splitter, so that it can effectively ensure the cleanliness of the equipment during the heat dissipation process without affecting the heat dissipation effect. This can effectively prevent dust and other contaminants from entering the optical splitter and help extend the service life of the equipment.
[0005] This application provides a PLC optical splitter that is easy to maintain, and adopts the following technical solution:
[0006] A PLC optical splitter that is easy to maintain includes a splitter body, the end of which is provided with a corresponding plug terminal for optical fiber insertion, and a heat dissipation vent is provided through the side of the splitter body, and a heat dissipation component is added to the heat dissipation vent.
[0007] The heat dissipation assembly includes a driving component and a lifting plate. Both the driving component and the lifting plate are slidably disposed in the vertical direction, and the driving component and the lifting plate slide in opposite directions in the vertical direction. A movable plate is slidably installed on the side of the driving component away from the splitter body in the vertical direction.
[0008] By adopting the above technical solution, when the splitter body does not require heat dissipation, the drive unit is located inside the heat dissipation vent, sealing it, and the lifting plate is located on top of the drive unit. When the splitter body requires heat dissipation, the drive unit rises and drives the lifting plate to fall. The lifting plate descends into the heat dissipation vent and seals it, dividing the vent into two independent chambers. In this state, the heat accumulated inside the splitter body enters the left chamber and is temporarily stored. Simultaneously, because the lifting plate seals the heat dissipation vent, external dust and contaminants are blocked from entering the splitter body, effectively preventing external dust and contaminants from entering and affecting its normal operation.
[0009] Once the heat within the splitter body has been temporarily stored, the drive unit descends, and the lifting plate rises until the drive unit re-seals the heat dissipation vent. In this state, the heat is temporarily stored within the heat dissipation vent. At this point, the movable plate on the drive unit is opened upwards, allowing the temporarily stored heat within the heat dissipation vent to be discharged from the movable plate to the outside of the splitter body.
[0010] This configuration allows for timely heat dissipation from the splitter body to the outside while effectively preventing external dust and contaminants from entering the splitter body and affecting its normal operation through the drive components and lifting plate. This optimizes the heat dissipation process of the optical splitter, ensuring cleanliness of the equipment during the heat dissipation process without affecting the heat dissipation effect. It also effectively prevents dust and other contaminants from entering the optical splitter, thus extending the service life of the equipment.
[0011] Preferably, a driving assembly is provided between the driving component and the lifting plate, and the driving component drives the lifting plate to move up and down in the vertical direction through the driving assembly;
[0012] The drive assembly includes a first wedge, a second wedge, and a third wedge. The first wedge is integrally formed on the top of the drive member in a vertical direction. The second wedge is horizontally positioned, and both the end of the second wedge near the first wedge and the end of the second wedge near the third wedge are wedge-shaped. The third wedge is integrally formed on the top of the lifting plate in a vertical direction. The end of the first wedge away from the drive member and the second wedge are wedge-shaped together. The end of the third wedge away from the lifting plate and the second wedge are wedge-shaped together. A lever is integrally formed on the side of the drive member away from the splitter body in a horizontal direction.
[0013] By adopting the above technical solution, when the splitter body needs to dissipate heat, the drive component is moved upward by the toggle plate. During the upward movement of the drive component, the first wedge block is simultaneously driven to rise. During the upward movement of the first wedge block, the second wedge block pushes the second wedge block to slide away from the first wedge block. During the sliding movement of the second wedge block, the third wedge block drives the third wedge block to move downward, and then the third wedge block drives the lifting plate to descend until the lifting plate seals the heat dissipation port.
[0014] Preferably, a support plate for supporting the second wedge is fixed on the side wall of the splitter body. The bottom of the support plate has a groove along its length. A corresponding slider is integrally formed on the top of the second wedge. The slider is slidably installed in the groove. A return spring is installed vertically between the top of the drive member and the top of the lifting plate and the side wall of the splitter body.
[0015] By adopting the above technical solution, the second wedge is stably supported by a support plate, and the stability of the second wedge during sliding is further enhanced by a sliding groove and a slider. A return spring is used to assist the drive component and the lifting plate in resetting the wedge.
[0016] Preferably, the side wall of the driving component is provided with a first movable groove in the vertical direction, the movable plate is slidably installed in the first movable groove, and the side wall of the movable plate is integrally formed with a handle.
[0017] By adopting the above technical solution, the first movable groove provides space for the sliding of the movable plate. At the same time, the handle facilitates the sliding of the movable plate.
[0018] Preferably, the side wall of the splitter body is provided with a water storage cavity for storing cooling water. The top of the splitter body is provided with a cooling channel that is in communication with the water storage cavity. A pressure plate is provided in the water storage cavity in the horizontal direction. The pressure plate is slidably arranged in the vertical direction. A first connecting rod is integrally formed at one end of the pressure plate in the vertical direction. A second connecting rod is integrally formed between the bottom of the first connecting rod and the driving component. The second connecting rod is horizontally arranged.
[0019] By adopting the above technical solution, when the splitter body needs to dissipate heat, the drive component drives the first link to rise during the rising process through the second link. At the same time as the first link rises, it drives the pressure plate to rise, so that the pressure plate can force the cooling water in the water storage chamber into the cooling channel. While the cooling water flows in the cooling channel, it further carries away the heat in the splitter body, which helps to improve the heat dissipation effect of the splitter body.
[0020] Preferably, a sealing plate for blocking the cooling channel is added vertically to the top of the pressure plate, and a third connecting rod is integrally formed between the sealing plate and the pressure plate. A second movable groove is opened on the inner wall of the top of the water storage cavity for the sealing plate to slide accordingly, and the sealing plate slides vertically in the second movable groove.
[0021] By adopting the above technical solution, when the splitter body does not need to dissipate heat, the sealing plate blocks the cooling channel, preventing the cooling water in the water storage chamber from entering the cooling channel. When the splitter body needs to dissipate heat, the pressure plate moves upward, pushing the sealing plate upward in the second movable groove via the third connecting rod. At this time, the water inlet of the cooling channel gradually opens, and the pressure plate gradually forces the cooling water into the cooling channel as it moves upward.
[0022] Preferably, a guide plate is installed along the length of the cooling channel at the top of the splitter body. The guide plate is inclined, with the side closer to the water storage chamber at a high position and the side farther from the water storage chamber at a low position.
[0023] Two drive gears are vertically spaced within the cooling channel on the side wall of the splitter body. Two impellers are installed on the side of the splitter body away from the heat dissipation port. The two impellers are connected to the two drive gears via corresponding shafts.
[0024] By adopting the above technical solution and setting the guide plate at an angle, the cooling water can flow more quickly and efficiently in the cooling channel after entering it, thus achieving higher heat dissipation efficiency.
[0025] After entering the cooling channel on the side wall of the splitter, the cooling water flows downwards, driving the drive gear to rotate. This drive gear, in turn, rotates the corresponding impeller within the splitter body. During rotation, the impeller effectively blows heat from within the splitter body to the heat dissipation vents for temporary storage, further improving the splitter's heat dissipation. The cooling channel is open on the side away from the water storage chamber, allowing cooling water to drain to the outside of the splitter body. When heat dissipation is not required, the side of the cooling channel away from the water storage chamber can be sealed with a corresponding plate.
[0026] Preferably, a guide groove is formed in the cooling channel on the side wall of the splitter body along the vertical direction, and the guide groove is located directly above one side of the drive gear.
[0027] By adopting the above technical solution, the cooling water can be precisely and continuously applied to the same side of the drive gear through the guide channel, thereby effectively ensuring the stability of the drive gear during rotation.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. When the splitter body does not require cooling, the drive unit is located inside the heat dissipation vent, sealing it, and the lifting plate is positioned on top of the drive unit. When the splitter body requires cooling, the drive unit rises, driving the lifting plate to descend. The lifting plate descends into the heat dissipation vent and seals it, dividing the vent into two independent chambers. In this state, the heat accumulated inside the splitter body enters the left chamber and is temporarily stored. Simultaneously, because the lifting plate seals the heat dissipation vent, external dust and contaminants are blocked from entering the splitter body, effectively preventing them from affecting its normal operation.
[0030] Once the heat within the splitter body has been temporarily stored, the drive unit descends, and the lifting plate rises until the drive unit re-seals the heat dissipation vent. In this state, the heat is temporarily stored within the heat dissipation vent. At this point, the movable plate on the drive unit is opened upwards, allowing the temporarily stored heat within the heat dissipation vent to be discharged from the movable plate to the outside of the splitter body.
[0031] This configuration can effectively prevent external dust and contaminants from entering the splitter body and affecting its normal operation by timely dissipating heat from the splitter body to the outside through the drive components and lifting plate. This optimizes the heat dissipation process of the optical splitter, ensuring that the equipment remains clean during the heat dissipation process without affecting the heat dissipation effect. This effectively prevents dust and other contaminants from entering the optical splitter, which helps to extend the service life of the equipment.
[0032] 2. When the splitter body needs to dissipate heat, the drive unit drives the first link to rise through the second link during the rising process. The first link drives the pressure plate to rise at the same time, so that the pressure plate can force the cooling water in the water storage chamber into the cooling channel. While the cooling water flows in the cooling channel, it further carries away the heat in the splitter body, which helps to improve the heat dissipation effect of the splitter body.
[0033] 3. By tilting the guide plate, the cooling water can flow more quickly and efficiently in the cooling channel after entering it, thus achieving higher heat dissipation efficiency.
[0034] After entering the cooling channel on the side wall of the splitter, the cooling water flows downwards, driving the drive gear to rotate. This drive gear, in turn, rotates the corresponding impeller within the splitter body. During rotation, the impeller effectively blows heat from within the splitter body to the heat dissipation vents for temporary storage, further improving the splitter's heat dissipation. The cooling channel is open on the side away from the water storage chamber, allowing cooling water to drain to the outside of the splitter body. When heat dissipation is not required, the side of the cooling channel away from the water storage chamber can be sealed with a corresponding plate. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below.
[0046] Example:
[0047] This application discloses a PLC optical splitter that is easy to maintain, referring to... Figure 1 and Figure 2 The system includes a splitter body 1, with corresponding plug terminals 2 at its ends for fiber optic cable insertion. A heat dissipation vent 3 is provided through the side of the splitter body 1, and a heat dissipation assembly 4 is installed at the vent 3. When the splitter body 1 does not require heat dissipation, the heat dissipation assembly 4 seals the vent 3 to effectively ensure the stability of the fiber optic cable within the splitter body 1. When the splitter body 1 requires heat dissipation, the heat dissipation assembly 4 opens the vent 3 for heat dissipation.
[0048] Reference Figure 2 and Figure 3 The heat dissipation component 4 includes a driving component 41 and a lifting plate 42. Both the driving component 41 and the lifting plate 42 are slidably arranged in the vertical direction. The driving component 41 has an overall "U" shaped structure, and the lifting plate 42 is a cuboid plate. The lifting plate 42 is located on the top of the driving component 41, and the driving component 41 and the lifting plate 42 slide in opposite directions in the vertical direction: when the driving component 41 rises, it drives the lifting plate 42 to fall, and when the driving component 41 falls, it drives the lifting plate 42 to rise.
[0049] Reference Figure 2 , Figure 3 as well as Figure 4 A movable plate 5 is slidably mounted on the side of the drive component 41 away from the splitter body 1 in the vertical direction. The movable plate 5 is in the shape of a cuboid.
[0050] When the splitter body 1 does not require heat dissipation, the drive unit 41 is located inside the heat dissipation port 3, sealing the port 3, and the lifting plate 42 is located on top of the drive unit 41. When the splitter body 1 requires heat dissipation, the drive unit 41 rises and drives the lifting plate 42 to fall. The lifting plate 42 descends into the heat dissipation port 3 and seals it, dividing the heat dissipation port 3 into two independent chambers, left and right. In this state, the heat accumulated inside the splitter body 1 enters the left chamber and is temporarily stored. At the same time, because the lifting plate 42 is sealing the heat dissipation port 3, external dust and contaminants are blocked from entering the splitter body 1, effectively preventing external dust and contaminants from entering the splitter body 1 and affecting its normal operation.
[0051] After the heat in the splitter body 1 is temporarily stored, the drive unit 41 descends, and the lifting plate 42 begins to rise until the drive unit 41 re-seals the heat dissipation port 3. In this state, the heat is temporarily stored in the heat dissipation port 3. At this time, the movable plate 5 on the drive unit 41 is opened upwards, and the temporarily stored heat in the heat dissipation port 3 is discharged from the movable plate 5 to the outside of the splitter body 1.
[0052] This configuration allows for timely heat dissipation from the splitter body 1 to the outside while effectively preventing external dust and contaminants from entering the splitter body 1 and affecting its normal operation through the drive unit 41 and lifting plate 42. This optimizes the heat dissipation process of the optical splitter, ensuring that the equipment remains clean during the heat dissipation process without affecting the heat dissipation effect. This effectively prevents dust and other contaminants from entering the optical splitter, thus extending the service life of the equipment.
[0053] The outside of the splitter body 1 is fitted with a corresponding plate for sealing the drive unit 41 and the lifting plate 42, so as to effectively ensure the integrity of the splitter body 1.
[0054] Specifically, the lifting plate 42 is positioned at the top of the drive member 41 at the end of the drive member 41 that is away from the splitter body 1. This results in the lifting plate 42 descending into the heat dissipation port 3, with a larger chamber on the side closer to the splitter body 1 and a smaller chamber on the side farther from the splitter body 1, which is beneficial for storing more heat.
[0055] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 A drive assembly 6 is provided between the drive component 41 and the lifting plate 42. The drive component 41 drives the lifting plate 42 to move up and down in the vertical direction through the drive assembly 6.
[0056] Reference Figure 2 , Figure 3 as well as Figure 4 The drive assembly 6 includes a first wedge 61, a second wedge 62, and a third wedge 63. The first wedge 61 is integrally formed vertically on the top of the drive member 41. The second wedge 62 is horizontally positioned, and both the end of the second wedge 62 near the first wedge 61 and the end of the second wedge 62 near the third wedge 63 are wedge-shaped. The third wedge 63 is integrally formed vertically on the top of the lifting plate 42. The end of the first wedge 61 away from the drive member 41 engages with the second wedge 62 in a wedge shape, and the end of the third wedge 63 away from the lifting plate 42 also engages with the second wedge 62 in a wedge shape.
[0057] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 The drive component 41 has a lever 7 integrally formed on the side away from the splitter body 1 in the horizontal direction. When the splitter body 1 needs to dissipate heat, the drive component 41 is moved upward by the lever 7. During the upward movement, the drive component 41 drives the first wedge 61 to rise. During the upward movement, the first wedge 61 pushes the second wedge 62 to slide away from the first wedge 61. During the sliding movement, the second wedge 62 drives the third wedge 63 to move downward, and then drives the lifting plate 42 to descend through the third wedge 63 until the lifting plate 42 seals the heat dissipation port 3.
[0058] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 A support plate 8 is welded to the side wall of the splitter body 1 to support the second wedge 62. The bottom of the support plate 8 has a groove along its length, and a corresponding slider is integrally formed on the top of the second wedge 62, slidingly mounted within the groove. The support plate 8 provides stable support for the second wedge 62, and the groove and slider further enhance the stability of the second wedge 62 during sliding. Simultaneously, a return spring 9 is vertically installed between the top of the drive component 41 and the top of the lifting plate 42 and the side wall of the splitter body 1, assisting the drive component 41 and the lifting plate 42 in resetting.
[0059] Specifically, refer to Figure 4 and Figure 5 The drive component 41 has a first movable groove 10 formed vertically on its side wall. The movable plate 5 is slidably installed in the first movable groove 10, which provides space for the sliding of the movable plate 5. At the same time, the side wall of the movable plate 5 is integrally formed with a handle 11, which facilitates the sliding of the movable plate 5 up and down.
[0060] Furthermore, referring to Figure 2 and Figure 6The splitter body 1 has a water storage cavity 12 on its side wall for storing cooling water. A cooling channel 13 is also provided on the top of the splitter body 1, and the cooling channel 13 communicates with the water storage cavity 12. A pressure plate 14 is horizontally positioned within the water storage cavity 12, and the pressure plate 14 slides vertically. A first connecting rod 15 is integrally formed at one end of the pressure plate 14 vertically, and a second connecting rod 16 is integrally formed between the bottom of the first connecting rod 15 and the drive component 41, and the second connecting rod 16 is horizontally positioned.
[0061] When the splitter body 1 needs to dissipate heat, the drive component 41 drives the first link 15 to rise through the second link 16 during the upward process. The first link 15 drives the pressure plate 14 to rise at the same time, so that the pressure plate 14 can force the cooling water in the water storage chamber 12 into the cooling channel 13. While the cooling water flows in the cooling channel 13, it further carries away the heat in the splitter body 1, which helps to improve the heat dissipation effect of the splitter body 1.
[0062] Specifically, refer to Figure 2 , Figure 6 as well as Figure 7 A sealing plate 17 for sealing the cooling channel 13 is added vertically to the top of the pressure plate 14. A third connecting rod 18 is integrally formed between the sealing plate 17 and the pressure plate 14. A second movable groove 19 is opened on the inner wall of the top of the water storage cavity 12 for the sealing plate 17 to slide. The sealing plate 17 slides vertically in the second movable groove 19.
[0063] When the splitter body 1 does not require heat dissipation, the sealing plate 17 blocks the cooling channel 13, preventing the cooling water in the water storage chamber 12 from entering the cooling channel 13. When the splitter body 1 requires heat dissipation, the pressure plate 14 moves upward, pushing the sealing plate 17 upward in the second movable groove 19 via the third connecting rod 18. At this time, the water inlet of the cooling channel 13 gradually opens, and the pressure plate 14 gradually forces the cooling water into the cooling channel 13 during its upward movement.
[0064] Furthermore, referring to Figure 2 and Figure 8 A guide plate 20 is installed along the length of the cooling channel 13 at the top of the splitter body 1. The guide plate 20 is inclined, with the side closer to the water storage chamber 12 at a higher position and the side farther from the water storage chamber 12 at a lower position. By tilting the guide plate 20, the cooling water can flow more quickly and efficiently in the cooling channel 13 after entering it, thus achieving higher heat dissipation efficiency.
[0065] Meanwhile, two drive gears 21 are installed vertically at intervals in the cooling channel 13 located on the side wall of the splitter body 1, and two impellers 22 are installed on the side of the splitter body 1 away from the heat dissipation port 3. The two impellers 22 are connected to the two drive gears 21 respectively through corresponding rotating shafts.
[0066] After entering the cooling channel 13 on the side wall of the splitter, the cooling water drives the drive gear 21 to rotate as it flows downwards. The drive gear 21 then drives the corresponding impeller 22 to rotate within the splitter body 1. During rotation, the impeller 22 effectively blows heat from the splitter body 1 to the heat dissipation port 3 for temporary storage, further improving the heat dissipation effect of the splitter body 1. The side of the cooling channel 13 away from the water storage chamber 12 is open, and the cooling water is discharged to the outside of the splitter body 1 through this side. When heat dissipation is not required, the side of the cooling channel 13 away from the water storage chamber 12 can be sealed by a corresponding plate.
[0067] Specifically, refer to Figure 8 and Figure 9 A guide groove 23 is provided vertically in the cooling channel 13 on the side wall of the splitter body 1. The top of the guide groove 23 is located directly above one side of the drive gear 21. The guide groove 23 allows the cooling water to act precisely and continuously on the same side of the drive gear 21, thereby effectively ensuring the stability of the drive gear 21 during rotation.
[0068] The implementation principle of a PLC optical splitter that is easy to maintain according to an embodiment of this application is as follows:
[0069] When the splitter body 1 does not require heat dissipation, the drive unit 41 is located inside the heat dissipation port 3, sealing the port 3, and the lifting plate 42 is located on top of the drive unit 41. When the splitter body 1 requires heat dissipation, the drive unit 41 rises and drives the lifting plate 42 to fall. The lifting plate 42 descends into the heat dissipation port 3 and seals it, dividing the heat dissipation port 3 into two independent chambers, left and right. In this state, the heat accumulated inside the splitter body 1 enters the left chamber and is temporarily stored. At the same time, because the lifting plate 42 is sealing the heat dissipation port 3, external dust and contaminants are blocked from entering the splitter body 1, effectively preventing external dust and contaminants from entering the splitter body 1 and affecting its normal operation.
[0070] After the heat in the splitter body 1 is temporarily stored, the drive unit 41 descends, and the lifting plate 42 begins to rise until the drive unit 41 re-seals the heat dissipation port 3. In this state, the heat is temporarily stored in the heat dissipation port 3. At this time, the movable plate 5 on the drive unit 41 is opened upwards, and the temporarily stored heat in the heat dissipation port 3 is discharged from the movable plate 5 to the outside of the splitter body 1.
[0071] This configuration allows for timely heat dissipation from the splitter body 1 to the outside while effectively preventing external dust and contaminants from entering the splitter body 1 and affecting its normal operation through the drive unit 41 and lifting plate 42. This optimizes the heat dissipation process of the optical splitter, ensuring that the equipment remains clean during the heat dissipation process without affecting the heat dissipation effect. This effectively prevents dust and other contaminants from entering the optical splitter, thus extending the service life of the equipment.
[0072] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
