Description

Technical Field

[0001] This utility model relates to the field of coupling device technology, and in particular to a fiber optic rapid alignment coupling device. Background Technology

[0002] Fiber optic coupling refers to the process of connecting and transmitting light sources (such as lasers) or optical signals to optical fibers. The purpose of fiber optic coupling is to efficiently transfer optical energy into the fiber so that optical signals can be transmitted and processed within it. Alignment devices are required during fiber optic coupling.

[0003] During fiber optic coupling, clamps are typically used to hold the fiber optic cable, and then an adjustment device is used to align the fiber optic cable with the axis of the laser. Since the diameter of the fiber optic cable varies, adjustment is required when changing to a different fiber optic cable, making the operation quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this invention is to provide a fiber optic rapid alignment and coupling device to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a fiber optic rapid alignment and coupling device, including a carrier plate. Two symmetrically arranged bases are fixedly mounted on the bottom of the carrier plate via bolts. A first support plate is fixedly connected to the top surface of the carrier plate. A laser is fixedly connected to one side of the first support plate. Two symmetrically arranged T-shaped sliding plates are slidably connected to the top surface of the carrier plate. A second support plate is fixedly connected to the top of the two T-shaped sliding plates. Both the first and second support plates are perpendicular to the carrier plate. A threaded sleeve is fixedly connected to the side of the second support plate closest to the first support plate. The inner wall of the threaded sleeve is threaded... The first support plate has a groove on its side away from the first support plate. A bidirectional lead screw is rotatably connected to the inside of the groove via a bearing. Two symmetrically arranged clamping plates are threaded onto the outer surface of the bidirectional lead screw. The fiber optic sleeve is located between the two clamping plates. A limiting plate is slidably connected to the inner side of each base. A storage box is fixedly connected between the two limiting plates. The top surface of the storage box is in contact with the bottom surface of the support plate.

[0007] Preferably, in any of the above solutions, a limiting groove is provided on the inner side of each base, and the limiting plate is slidably connected to the base through the limiting groove.

[0008] Preferably, in any of the above embodiments, a baffle plate is fixedly connected to the bottom surface of the support plate, and two symmetrically arranged magnetic disks are embedded in the side of the baffle plate near the storage box. The front of the magnetic disks is in contact with the back of the storage box, and the storage box is made of magnetic metal.

[0009] Preferably, in any of the above solutions, the inner wall of the groove is fixedly connected to two symmetrically arranged guide rods, and both clamping plates are slidably connected to the guide rods.

[0010] Preferably, in any of the above solutions, a clearance hole is provided through one side of the second support plate, the optical fiber sleeve is located inside the clearance hole, and the axis of the optical fiber core coincides with the center of the clearance hole.

[0011] Preferably, in any of the above schemes, a locking bolt is rotatably connected to the side of the second support plate away from the first support plate, and the bottom end of the locking bolt is in contact with the top surface of the bearing plate.

[0012] Preferably, in any of the above embodiments, a scale is embedded in the top surface of the support plate, and the scale is perpendicular to the second support plate.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] When laser coupling is required, the storage box can be pulled to move along the limiting groove. Then, a fiber optic core sleeve with a suitable inner diameter can be taken out from the storage box and screwed into the threaded sleeve. This makes it easy to change the appropriate fiber optic core sleeve according to different diameter fiber optic cores. The storage box can also store multiple fiber optic core sleeves. Then, the fiber optic core is inserted into the fiber optic core sleeve until it is between the two clamping plates. Then, the bidirectional screw is turned. Through the threaded drive, the two clamping plates can be moved closer to the fiber optic sleeve at the same time until the fiber optic sleeve is clamped. At this time, the fiber optic core is aligned with the axis of the laser, which can quickly complete the alignment operation when the fiber is installed. Attached Figure Description

[0024] As an optional technical solution of this utility model, a baffle plate 17 is fixedly connected to the bottom surface of the support plate 1. Two symmetrically arranged magnetic disks 18 are embedded in the side of the baffle plate 17 near the storage box 15. The front of the magnetic disks 18 is in contact with the back of the storage box 15. The storage box 15 is made of magnetic metal. The fact that the front of the magnetic disks 18 is in contact with the back of the storage box 15 ensures that the storage box 15 is firmly fixed.

[0025] As an optional technical solution of this utility model, the inner wall of the groove 11 is fixedly connected with two symmetrically arranged guide rods 19, and both clamping plates 13 are slidably connected to the guide rods 19.

[0029] A fiber optic rapid alignment and coupling device, the working principle of which is as follows:

[0030] 1): When laser coupling is required, the storage box 15 can be pulled to move along the limiting groove 16, and then the fiber core sleeve 8 with a suitable inner diameter can be taken out from the storage box 15 and screwed into the threaded sleeve 7.

[0031] 2): The storage box 15 facilitates the storage of multiple fiber optic core sleeves 8, and then the fiber optic core 9 is inserted into the fiber optic core sleeve 8.

[0032] 3): After the fiber optic sleeve 10 is positioned between the two clamping plates 13, twist the bidirectional screw 12. Through the threaded transmission, the two clamping plates 13 can be driven to approach the fiber optic sleeve 10 at the same time until the fiber optic sleeve 10 is clamped.

[0033] In summary, this fiber optic rapid alignment and coupling device allows for the following steps when laser coupling is required: The storage box 15 can be pulled along the limiting groove 16, allowing a fiber optic core sleeve 8 of suitable inner diameter to be removed from the storage box 15 and screwed into the threaded sleeve 7. This facilitates the replacement of the appropriate fiber optic core sleeve 8 with fiber optic cores 9 of different diameters. The storage box 15 also allows for the storage of multiple fiber optic core sleeves 8. The fiber optic core 9 is then inserted into the fiber optic core sleeve 8 until it is positioned between the two clamping plates 13 at the fiber optic sleeve 10 position. The bidirectional screw 12 is then turned, and the threaded drive causes the two clamping plates 13 to simultaneously approach the fiber optic sleeve 10 until it is clamped. At this point, the fiber optic core 9 coincides with the axis of the laser 4, enabling rapid alignment during fiber installation.
