Description

Technical Field

[0001] This utility model relates to the technical field of fiber distribution and adjustment devices, and more specifically, to a fiber distribution and adjustment mechanism for a wavelength division multiplexer. Background Technology

[0002] A wavelength division multiplexer (WDM) is a passive optical device used in optical fiber communication. It can transmit a set of optical wavelengths through a single optical fiber, thereby increasing the bandwidth of existing optical fibers.

[0003] Currently, commonly used wavelength division multiplexer (WDM) fiber optic adjustment devices require adjusting the center and spacing of the two fibers after clamping the dual-fiber pigtail and the lens, which is cumbersome and time-consuming, causing great inconvenience to users. For example, the WDM fiber optic adjustment device disclosed in publication number CN222145274U includes: a light source, a coupling frame, a clamping component, a first optical power meter, and a second optical power meter. The clamping component is fixed on the coupling frame to clamp the dual-fiber pigtail and the lens. The dual-fiber pigtail includes a first optical fiber and a second optical fiber. The first optical fiber is used to connect to the light source. The first optical power meter is located at the output end of the lens, and the second optical power meter is used to connect to the second optical fiber.

[0004] As can be seen from the above-disclosed scheme, the first gripper is connected to the optical coupler frame, the second gripper is connected to the bracket, and the bracket and the optical coupler frame are not connected. As a result, the center position of the clamped dual-fiber pigtail and the lens needs to be adjusted by a three-dimensional adjustment frame. After the center position is adjusted, the distance between the two also needs to be adjusted. This adjustment process is cumbersome and time-consuming, causing great inconvenience to the user and reducing the convenience of debugging. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a wavelength division multiplexer fiber matching and adjustment mechanism. This mechanism, through the setting of a first clamping component and a second clamping component, ensures that the center of the clamped dual-fiber tail and the lens are on the same axis, eliminating the need to adjust the center of both, greatly improving ease of use. Furthermore, through the setting of a lifting screw and a translation screw, not only can the height position of the adjustment table be precisely adjusted, but also the horizontal position of the moving block can be precisely adjusted, thereby accurately adjusting the distance between the clamped dual-fiber tail and the lens, further improving the convenience of adjustment.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A wavelength division multiplexer (WDM) fiber optic adjustment mechanism includes an adjustment mechanism body, a base fixedly connected to the bottom of the adjustment mechanism body, a height adjustment component slidably connected to one end of the adjustment mechanism body, an adjustment platform fixedly connected to one end of the height adjustment component, a sliding groove on the side of the adjustment platform, a moving block slidably connected to the inner wall of the sliding groove, a horizontal adjustment component threadedly connected to the side of the moving block, a first clamping component fixedly connected to the surface of the adjustment platform, and a second clamping component fixedly connected to the surface of the moving block. This WDM fiber optic adjustment mechanism, through the first and second clamping components, ensures that the centers of the clamped dual-fiber pigtail and the lens are on the same axis, eliminating the need for center adjustment and greatly improving ease of use. Furthermore, the lifting and translation screws allow for precise adjustment of both the height of the adjustment platform and the horizontal position of the moving block, thereby precisely adjusting the spacing between the clamped dual-fiber pigtail and the lens, further enhancing adjustment convenience.

[0008] Furthermore, the first clamping assembly includes a positioning seat, with symmetrical clamping blocks slidably connected to the inner side of the positioning seat, and clamping grooves surrounding the symmetrical clamping blocks. Guide grooves are slidably connected to the surface of the clamping blocks, and a spring is fixedly sleeved on one end of each clamping block. The spring is in a compressed state, so that the two clamping blocks have an automatic clamping function.

[0009] Furthermore, the height adjustment component includes a lifting column, one end of which is slidably connected to a storage slot. A lifting motor is fixedly connected to the bottom of the storage slot, and a lifting screw is fixedly connected to the output end of the lifting motor. The lifting screw can control the lifting height of the lifting column through a thread, thereby adjusting the height of the test bench.

[0010] Furthermore, the horizontal adjustment assembly includes a translation screw, which is rotatably connected to the side of the test bench via a bearing. An adjustment wheel is fixedly connected to one end of the translation screw, and an elastic block is fixedly sleeved on the surface of the translation screw. The surface of the elastic block contacts and presses against the side of the test bench, which can fix the rotational position of the translation screw through elastic force and prevent it from rotating arbitrarily.

[0011] Furthermore, one end of the movable block has an axially penetrating second threaded hole, the inner wall of which is threadedly connected to the surface of the translation screw. A limit strip is fixedly connected to the side of the movable block. The limit strip can ensure the horizontal position of the movable block and prevent it from rotating, so that the movable block can be quickly and accurately adjusted to its horizontal position by the translation screw.

[0012] Furthermore, the bottom of the lifting column has a first screw hole, the inner wall of the first screw hole is threaded to the surface of the lifting screw, and one end of the first screw hole is fixedly connected to a clearance groove, which has a clearance function and can store the lifting screw.

[0013] Furthermore, an anti-detachment sleeve is fixedly fitted onto the surface of the clamping block. The surface of the anti-detachment sleeve is slidably connected to the inner wall of the guide groove. The anti-detachment sleeve is made of wear-resistant elastic rubber to prevent the clamping block from moving arbitrarily and to provide a damping effect.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution, through the setting of the first clamping component and the second clamping component, makes the center of the clamped double fiber tail and the lens on the same axis, without the need to adjust the center of the two, which greatly improves the convenience of use.

[0016] (2) This solution, through the setting of lifting screw and translation screw, can not only accurately adjust the height position of the debugging platform, but also facilitate the accurate adjustment of the horizontal position of the moving block, thereby accurately adjusting the distance between the clamped double fiber tail and the lens, improving the debugging convenience.

The height adjustment component includes a lifting column 15. A storage slot 12 is slidably connected to one end of the lifting column 15. A lifting motor 13 is fixedly connected to the bottom of the storage slot 12. The lifting motor 13 is a forward and reverse reversible motor. A lifting screw 14 is fixedly connected to the output end of the lifting motor 13. The lifting screw 14 can control the lifting height of the lifting column 15 via a thread, thereby adjusting the height of the debugging platform 2. One end of the height adjustment component is fixedly connected to the debugging platform 2. The surface of the debugging platform 2 is on the same plane as the surface of the moving block 25. A sliding groove 21 is opened on the side of the debugging platform 2. A limiting groove is opened on the inner wall of the sliding groove 21. The inner wall of the limiting groove is connected to a limiting... The surface of strip 27 is slidably connected to ensure the stability of the moving position of the moving block 25. The inner wall of the slide groove 21 is slidably connected to the moving block 25. The side of the moving block 25 is threadedly connected to a horizontal adjustment component, which includes a translation screw 22. The translation screw 22 is rotatably connected to the side of the test bench 2 through a bearing. One end of the translation screw 22 is fixedly connected to an adjustment wheel 23. An elastic block 24 is fixedly sleeved on the surface of the translation screw 22. The surface of the elastic block 24 contacts and presses against the side of the test bench 2, which can fix the rotation position of the translation screw 22 by elastic force and prevent it from rotating randomly. The surface of the test bench 2 is fixedly connected to a first clamping component 3, and the surface of the moving block 25 is fixedly connected to a second clamping component 4. The second clamping component 4 and the first clamping component 3 have the same composition and size, and are used to clamp the dual-fiber tail and the lens, respectively.

[0027] The first clamping assembly 3 includes a positioning seat 31. Symmetrical clamping blocks 33 are slidably connected to the inner side of the positioning seat 31, and clamping grooves 36 are formed between the symmetrical clamping blocks 33. Guide grooves 32 are slidably connected to the surface of the clamping blocks 33. A spring 35 is fixedly sleeved at one end of the clamping block 33. The spring 35 is in a compressed state, so that the two clamping blocks 33 have an automatic clamping function. A second threaded hole 26 is opened at one end of the moving block 25. The inner wall of the second threaded hole 26 is threadedly connected to the surface of the translation screw 22. A limit strip 27 is fixedly connected to the side of the moving block 25. The limit strip 27 can ensure the horizontal position of the moving block 25 and prevent it from rotating, so that the moving block 25 can quickly and accurately adjust its horizontal movement position through the translation screw 22.

[0028] The bottom of the lifting column 15 has a first screw hole 17. The inner wall of the first screw hole 17 is threadedly connected to the surface of the lifting screw 14. One end of the first screw hole 17 is fixedly connected to a clearance groove 16. The clearance groove 16 has a clearance function and can store the lifting screw 14. The surface of the clamping block 33 is fixedly fitted with an anti-disengagement sleeve 34. The surface of the anti-disengagement sleeve 34 is slidably connected to the inner wall of the guide groove 32. The anti-disengagement sleeve 34 is made of wear-resistant elastic rubber to prevent the clamping block 33 from moving at will and has a damping function.

[0029] When using the wavelength division multiplexer fiber distribution adjustment mechanism, the two clamping blocks 33 of the first clamping component 3 can be manually separated first. Then, the dual-fiber pigtail is clamped and positioned in the clamping groove 36. Next, the lens is clamped onto the second clamping component 4 as described above. At this point, the center of the lens and the dual-fiber pigtail are on the same axis, eliminating the need for center adjustment. The horizontal movement position of the moving block 25 is then adjusted by rotating the translation screw 22, thereby adjusting the distance between the first clamping component 3 and the second clamping component 4, and thus the distance between the clamped dual-fiber pigtail and the lens. For users of different heights, the height of the adjustment table 2 can be adjusted according to actual needs. When the lifting motor 13 drives the lifting screw... When the lifting column 14 rotates clockwise, the lifting column 15 moves upward, increasing the height of the debugging platform 2. When the lifting motor 13 drives the lifting screw 14 to rotate counterclockwise, the lifting column 15 moves downward, reducing the height of the debugging platform 2. Through the first clamping component 3 and the second clamping component 4, the center of the clamped dual-fiber tail and the lens is on the same axis, eliminating the need to adjust their centers, greatly improving ease of use. Furthermore, through the lifting screw 14 and the translation screw 22, not only can the height of the debugging platform 2 be precisely adjusted, but the horizontal position of the moving block 25 can also be precisely adjusted, thereby precisely adjusting the distance between the clamped dual-fiber tail and the lens, improving debugging convenience.
