Description

Technical Field

[0001] This application relates to the field of optical fiber manufacturing and processing, and in particular to LC optical fiber error-proof clamps. Background Technology

[0002] LC fiber optic miniaturized connectors feature a 1.25mm diameter ceramic ferrule design, half the size of traditional SC / FC connectors, making them a fundamental transmission component in optical communication systems. They employ a push-pull modular latching structure, supporting quick one-handed insertion and removal. Combined with precise alignment of the high-precision ceramic ferrule and sleeve, they achieve low insertion loss (typically ≤0.3dB) and high return loss (UPC endface ≥50dB, APC endface ≥65dB). This product is available in single-mode (9μm core, supporting 10-40km long-distance transmission) and multimode (50 / 62.5μm core, suitable for high-speed transmission within 500m), compatible with various fiber specifications such as OM3 / OM4 and G.652 / G.657. Leveraging its high-density cabling advantages and stable transmission performance, LC fiber optics are widely used in data centers, 5G base stations, telecommunications backbone networks, industrial automation, and medical equipment, meeting multi-rate transmission requirements from 10Gbps to 1.6Tbps.

[0003] During the production of LC optical fibers, the fiber optic connectors need to be manually assembled. When assembling them manually, personnel need to use clamps to fix the outer shell of the fiber optic connector, and then insert the ferrule into the outer shell for assembly. However, traditional clamps only have a limiting structure to restrict the outer shell of the fiber optic connector and no other structures. Since fiber optic connectors are usually small in size, this makes it difficult for personnel to remove the outer shell of the fiber optic connector after assembly. If personnel pull the ferrule directly, it is easy to damage the ferrule and affect the service life of the optical fiber. Utility Model Content

[0004] The purpose of this invention is to provide an LC fiber optic fault-proof clamp to solve the problems mentioned in the background art.

[0005] This utility model provides an LC fiber optic anti-foolproof clamp, comprising:

[0006] The base has a clamp body installed on its top by screws. The top of the clamp body has a foolproof clamping groove, a sliding groove and a spring-loaded groove. The sliding groove is located between the foolproof clamping groove and the spring-loaded groove, and the sliding groove is connected to the foolproof clamping groove and the spring-loaded groove.

[0007] A slider is slidably installed in a groove, a locking block is fixedly installed on one side of the anti-foolproof clamping groove, and a first magnetic block is fixedly installed at the bottom of the anti-foolproof clamping groove.

[0008] The top frame is located below the anti-foolproof clamping groove. A linkage plate is fixedly installed on one side of the top frame and below the slider. A second magnetic block that is magnetically connected to the first magnetic block is fixedly installed on the top side of the linkage plate.

[0009] A reset assembly is located within a spring groove and is used to drive a slider to reciprocate within the groove.

[0010] By adopting the above technical solution, the operator moves the slider towards the insertion post, thereby driving the insertion post into the slot and compressing the reset spring. At this time, the slider will move the locking block away from the fiber optic head shell, while the limiting magnetic block will repel the auxiliary magnetic plate and push upward. In addition, the first magnetic block will move with the slider to the top of the docking slot and attract the second magnetic block upward under the action of magnetic force. This ensures that the slider and the second magnetic block will drive the linkage plate to move upward in the docking slot when they move. The linkage plate will drive the top frame to extend upward from the top slot when it moves, thereby pushing the assembled fiber optic head shell in the anti-foolproof clamping slot upward.

[0011] Preferably, the reset component includes:

[0012] A slot, wherein the slot is formed on the inner sidewall of the spring groove;

[0013] The insert and the return spring are both fixedly installed on one side of the slider and located in the spring groove. The return spring is sleeved on the outer circumferential wall of the insert. One side of the insert passes through the spring groove and extends into the slot.

[0014] By adopting the above technical solution, the reset component allows the slider to slide back into the groove after the operator moves it towards the return groove. The reset spring releases the compression force, thus eliminating the need for manual operation.

[0015] Preferably, the bottom wall of the anti-foolproof clamping groove is provided with a top groove that is adapted to slide with the top frame. The top of the top frame passes through the top groove and extends into the anti-foolproof clamping groove. A connecting groove is provided on one side of the top groove and below the slider. A docking groove communicating with the spring groove is provided on the top side of the connecting groove. The second magnetic block is slidably adapted to the docking groove.

[0016] By adopting the above technical solution, the top of the top frame can be hidden in the top groove and flush with the inner bottom wall of the anti-foolproof clamping groove, so that the assembly of the fiber optic head housing will not be affected when the fiber optic head housing is inserted into the anti-foolproof clamping groove for assembly.

[0017] Preferably, both sides of the slide groove are provided with inner grooves that communicate with the connecting groove, and the inner grooves are connected to one side of the inner wall of the slide groove. The top of the linkage plate is fixedly installed with a sliding column that is slidably connected to the inner groove. An auxiliary magnetic plate is fixedly installed on the top of the sliding column and above the slide groove, and the auxiliary magnetic plate is slidably adapted to the inner groove.

[0018] By adopting the above technical solution, the inner groove can restrict the sliding column and auxiliary magnetic plate to move only up and down, preventing the sliding column and auxiliary magnetic plate from sliding and deviating, thus affecting the movement of the linkage plate.

[0019] Preferably, the linkage plate is slidably adapted to the connecting groove, the inner groove has an inverted L-shaped structure, and the combination of the sliding column and the auxiliary magnetic plate has an inverted L-shaped structure.

[0020] By adopting the above technical solution, and by moving the auxiliary magnetic plate within the inner groove, when the limiting magnetic block moves to below the auxiliary magnetic plate, the auxiliary magnetic plate will stably move from the inner bottom wall to the inner top wall of the inner groove under the action of magnetic repulsion.

[0021] Preferably, both sides of the slide groove are provided with limiting grooves that communicate with the inner groove, and both sides of the slider are fixedly installed with limiting magnetic blocks that are adapted to slide in the limiting grooves.

[0022] By adopting the above technical solution, the slider can be driven to move within the groove by the movement of the limiting magnetic block along the limiting groove, preventing the slider from detaching from the groove and allowing the slider to move only back and forth.

[0023] Preferably, the limiting magnetic block is located below the auxiliary magnetic plate, and the limiting magnetic block and the auxiliary magnetic plate are magnetically repelled.

[0024] By adopting the above technical solution, through the mutual repulsion of magnetic force between the limiting magnetic block and the auxiliary magnetic plate, the limiting magnetic block can stably move the auxiliary magnetic plate upward when it moves to the bottom of the auxiliary magnetic plate, thereby assisting the linkage plate to move upward in the connecting groove.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When the personnel move the slider and drive the locking block to unlock the fiber optic head shell in the foolproof clamping slot, the slider will magnetically attract the second magnetic block upward in the connecting slot to the docking slot through the first magnetic block. Then, through the linkage plate, the top frame will move upward in the top slot, thereby directly pushing out the fiber optic head shell located in the foolproof clamping slot. This allows the fiber optic head shell to be automatically pushed out of the foolproof clamping slot while it is being unlocked, increasing the contact area between the personnel's fingers and the fiber optic head shell, making it easier for personnel to remove the assembled fiber optic head shell from the foolproof clamping slot.

[0027] 2. The limiting magnetic block slides synchronously along the slide groove as the slider is moved. When the limiting magnetic block slides to the bottom of the auxiliary magnetic plate, the limiting magnetic block will repel the auxiliary magnetic plate under the action of magnetic force, thereby pushing the auxiliary magnetic plate upward. This will drive the sliding column to lift the linkage plate upward, thereby improving the smoothness of the top frame sliding upward in the top groove. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0035] This application discloses an LC fiber optic fault-proof clamp.

[0036] Reference Figure 1 and Figure 3 The LC fiber optic anti-mistake clamp includes: a base 10, and a clamp body 11 is installed on the top of the base 10 by screws. Personnel can unscrew the screws and then remove the clamp body 11 from the base 10. The top of the clamp body 11 is provided with an anti-mistake clamping groove 12, a sliding groove 13 and a spring-loaded groove 14. The sliding groove 13 is located between the anti-mistake clamping groove 12 and the spring-loaded groove 14, and the sliding groove 13 communicates with the anti-mistake clamping groove 12 and the spring-loaded groove 14. The structure inside the sliding groove 13 can easily enter the anti-mistake clamping groove 12 and the spring-loaded groove 14.

[0037] The slider 21 is slidably installed in the slide groove 13. A locking block 24 is fixedly installed on one side of the anti-foolproof clamping groove 12. A first magnetic block 23 is fixedly installed at the bottom of the anti-foolproof clamping groove 12. By sliding the slider 21 in the slide groove 13, the locking block 24 can be driven to fix the fiber optic head shell in the anti-foolproof clamping groove 12. At the same time, the limiting magnetic block 22 and the first magnetic block 23 can be driven to move stably.

[0038] The top frame 27 is located below the foolproof clamping groove 12. A linkage plate 28 is fixedly installed on one side of the top frame 27 and below the slider 21. A second magnetic block 29, which is magnetically connected to the first magnetic block 23, is fixedly installed on the top side of the linkage plate 28. The top frame 27 can lift the fiber optic head shell in the foolproof clamping groove 12 upward, making it easier for personnel to remove the fiber optic head shell from the foolproof clamping groove 12.

[0039] The reset component is located in the spring groove 14 and is used to drive the slider 21 to reciprocate within the slide groove 13.

[0040] In this process, the operator moves the slider 21 toward the insertion post 25, thereby driving the insertion post 25 into the slot 20 and compressing the reset spring 26. At this time, the slider 21 will move the locking block 24 away from the fiber optic head shell, while the limiting magnetic block 22 will repel the auxiliary magnetic plate 31 and push upward. In addition, the first magnetic block 23 will move with the slider 21 to the top of the docking slot 19 and attract the second magnetic block 29 upward under the action of magnetic force. This ensures that the slider 30 and the second magnetic block 29 will drive the linkage plate 28 to move upward in the connecting slot 17 when they move. The linkage plate 28 will drive the top frame 27 to extend upward from the top slot 18 when it moves, thereby pushing the assembled fiber optic head shell in the anti-foolproof clamping slot 12 upward.

[0041] When the operator moves the slider 21 and drives the locking block 24 to unlock the fiber optic head housing in the foolproof clamping slot 12, the slider 21 will magnetically attract the second magnetic block 29 upward in the connecting slot 17 to the docking slot 19 through the first magnetic block 23. Then, through the linkage plate 28, the top frame 27 will move upward in the top slot 18, thereby directly pushing out the fiber optic head housing located in the foolproof clamping slot 12. Thus, the fiber optic head housing can be automatically pushed out of the foolproof clamping slot 12 at the same time as it is unlocked, increasing the contact area between the operator's fingers and the fiber optic head housing.

[0042] refer to Figure 2 and Figure 5 The reset component includes:

[0043] Slot 20 is formed on the inner side wall of spring groove 14;

[0044] The insert 25 and the return spring 26 are both fixedly installed on one side of the slider 21 and located in the spring groove 14. The return spring 26 is sleeved on the outer circumferential wall of the insert 25. One side of the insert 25 passes through the spring groove 14 and extends into the slot 20. With the reset assembly, after the personnel move the slider 21 towards the spring groove 14, the return spring 26 releases the compression force to drive the slider 21 to slide back into the slide groove 13, so that the personnel do not need to manually move the slider 21 to reset.

[0045] refer to Figure 1 and Figure 2 The bottom wall of the anti-foolproof clamping groove 12 is provided with a top groove 18 that is slidably adapted to the top frame 27. The top of the top frame 27 passes through the top groove 18 and extends into the anti-foolproof clamping groove 12. A connecting groove 17 is provided on one side of the top groove 18 and below the slider 21. A docking groove 19 that communicates with the spring groove 14 is provided on the top side of the connecting groove 17. The second magnetic block 29 is slidably adapted to the docking groove 19. The top of the top frame 27 can be hidden in the top groove 18 and flush with the bottom wall of the anti-foolproof clamping groove 12. Therefore, when the fiber optic head shell is inserted into the anti-foolproof clamping groove 12 for assembly, it will not affect the assembly of the fiber optic head shell.

[0046] refer to Figure 3 Both sides of the slide groove 13 are provided with inner grooves 16 that communicate with the connecting groove 17, and the inner grooves 16 are connected to one side of the inner wall of the slide groove 13. The top of the linkage plate 28 is fixedly installed with a sliding column 30 that is slidably connected to the inner groove 16. The top of the sliding column 30 and above the slide groove 13 is fixedly installed with an auxiliary magnetic plate 31, and the auxiliary magnetic plate 31 is slidably adapted to the inner groove 16. The inner groove 16 can restrict the sliding column 30 and the auxiliary magnetic plate 31 to move only up and down, preventing the sliding column 30 and the auxiliary magnetic plate 31 from sliding and deviating and affecting the movement of the linkage plate 28.

[0047] refer to Figure 3 and Figure 4 The linkage plate 28 and the connecting groove 17 are slidably adapted. The inner groove 16 has an inverted L-shaped structure. The sliding column 30 and the auxiliary magnetic plate 31 are combined to form an inverted L-shaped structure. As the auxiliary magnetic plate 31 moves in the inner groove 16, when the limiting magnetic block 22 moves to the bottom of the auxiliary magnetic plate 31, the auxiliary magnetic plate 31 will move stably from the bottom wall to the top wall of the inner groove 16 under the action of magnetic repulsion.

[0048] refer to Figure 4 Both sides of the slide groove 13 are provided with limiting grooves 15 that communicate with the inner groove 16. Both sides of the slider 21 are fixedly installed with limiting magnetic blocks 22 that are adapted to slide in the limiting grooves 15. By moving the limiting magnetic blocks 22 along the limiting grooves 15, the slider 21 can be driven to move in the slide groove 13, preventing the slider 21 from disengaging from the slide groove 13, so that the slider 21 can only move back and forth.

[0049] refer to Figure 3 The limiting magnetic block 22 is located below the auxiliary magnetic plate 31, and the limiting magnetic block 22 and the auxiliary magnetic plate 31 repel each other magnetically. By means of mutual repulsion between the limiting magnetic block 22 and the auxiliary magnetic plate 31, the limiting magnetic block 22 can stably move the auxiliary magnetic plate 31 upward when it moves to the bottom of the auxiliary magnetic plate 31, thereby assisting the linkage plate 28 to move upward in the connecting groove 17.

[0050] The implementation principle of the LC fiber optic anti-mistake clamp in this application embodiment is as follows: First, the operator places the fiber optic head housing into the anti-mistake clamping groove 12. As the operator gradually inserts the fiber optic head into the anti-mistake clamping groove 12, the fiber optic head housing will contact the top of the locking block 24 and gradually push the locking block 24 towards the slider 21. At the same time, the slider 21 will also drive the ferrule 25 into the slot 20 and compress the locking block 24. After the fiber optic head housing is completely inserted into the anti-mistake clamping groove 12, one side of the locking block 24 will extend through the return spring 26 and directly insert into the pre-reserved opening in the fiber optic head housing, ensuring that the fiber optic head housing will not detach from the anti-mistake clamping groove 12. At this time, the operator can directly insert the ferrule into the fiber optic head housing for assembly. After assembly, the operator... The operator moves the slider 21 toward the insertion post 25, thereby driving the insertion post 25 into the slot 20 and compressing the reset spring 26. At this time, the slider 21 will move the locking block 24 away from the fiber optic head shell, while the limiting magnetic block 22 will repel the auxiliary magnetic plate 31 and push upward. In addition, the first magnetic block 23 will move with the slider 21 to the top of the docking slot 19 and attract the second magnetic block 29 upward under the action of magnetic force. This ensures that the slider 30 and the second magnetic block 29 will drive the linkage plate 28 to move upward in the connecting slot 17 when they move. The linkage plate 28 will drive the top frame 27 to extend upward from the top slot 18 when it moves, thereby pushing the assembled fiber optic head shell in the anti-foolproof clamping slot 12 upward, ensuring that the operator can accurately pick up the fiber optic head shell.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
