Abstract
Description
Technical Field
[0001] This utility model relates to the field of SMT surface mount technology, specifically to a BOX-packaged optical device coupling clamping structure. Background Technology
[0002] Box-packaged optical devices are a type of packaging used to encapsulate optical modules or components in optical communication systems. They primarily protect optical devices from external environmental factors (such as dust, humidity, and mechanical shock) while providing stable optical and electrical interfaces to ensure the performance and reliability of the optical devices. Box-packaged optical devices are widely used in fiber optic communication, data centers, 5G communication, and other fields.
[0003] In the coupling process of existing BOX-packaged optical devices, the position of the optical transmitter (TO) is typically adjusted by placing a square tube on an arbitrary plane and then clamping the BOX-packaged optical device with a horizontal clamping device. However, this method makes it difficult to guarantee the precise positioning of the BOX-packaged optical device during clamping. Furthermore, after coupling, the optical transmitter (TO) needs to be soldered onto the BOX-packaged optical device. If the position is inaccurate, misalignment may occur during the coupling and soldering processes, affecting the subsequent installation efficiency of the optical transmitter (TO) and optical fiber, as well as the final accuracy of laser beam propagation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figs. 1-2 This application proposes a BOX-packaged optical device coupling and clamping structure according to this embodiment, including a positioning base 2, a base 3 fixedly provided on the top of the positioning base 2, the base 3 being used to place the optical device body 1; positioning plates 4 are respectively provided on the front and rear sides of the upper side of the base 3, and the positioning plates 4 are provided with an adjustment structure 5 for adjusting the longitudinal position of the optical device body 1, which is used to perform preliminary and precise adjustment of the longitudinal position of the optical device body 1; the upper side of the base 3 is also provided with a clamping structure 6 for fixing the optical device body 1 in a set position.
[0020] Furthermore, the adjustment structure 5 is a key component for realizing the longitudinal position adjustment of the optical device. The adjustment structure 5 includes adjustment plates 51 respectively located inside the two positioning plates 4. The two adjustment plates 51 are respectively provided with connecting rods 52 on one side of the corresponding positioning plate 4. The connecting rods 52 are inserted into the corresponding positioning plate 4 and slidably connected to it. One of the connecting rods 52 passes through the corresponding positioning plate 4 and extends to the outside, with a limiting block 53 at its end. A spring 54 is also provided between the connecting rod 52 and the positioning plate 4. The spring 54 is sleeved on the connecting rod 52. This design gives the adjustment plate 51 a certain elastic buffering effect when it moves, avoiding damage to the optical device due to excessive adjustment.
[0021] Another connecting rod 52 has a threaded rotating rod 55 on the outer side of the positioning plate 4. The threaded rotating rod 55 passes through the positioning plate 4 and is threadedly connected to the corresponding connecting rod 52. The threaded rotating rod 55 is rotatably connected to the corresponding positioning plate 4. By rotating the threaded rotating rod 55, the connecting rod 52 can be driven to slide within the positioning plate 4, thereby driving the adjusting plate 51 to move longitudinally. This design can achieve precise adjustment of the longitudinal position of the optical device body 1, ensuring the positional accuracy of the optical device during the packaging process. At the same time, under the action of the spring 54, the two adjusting plates 51 clamp the optical device body 1 during the adjustment process. By cooperating with the threaded rotating rod 55 to adjust the position of one of the adjusting plates 51, the clamped optical device body 1 can be driven to adjust its longitudinal position. Moreover, the threaded connection provides high adjustment accuracy.
[0022] To further improve the stability and accuracy of the adjustment, guide rods 56 are provided at the corresponding positioning plates 4 for the two adjustment plates 51. The guide rods 56 pass through the corresponding positioning plates 4 and are slidably connected to them. The function of the guide rods 56 is to limit the movement direction of the adjustment plates 51, so that they move smoothly along the predetermined trajectory, avoid deviation or shaking during the adjustment process, and further improve the reliability of the optical device positioning.
[0023] Furthermore, the clamping structure 6 is used to fix the optical device body 1 on the base 3. The clamping structure 6 includes a transversely arranged bidirectional screw 61. A movable groove 62 is transversely opened on the upper side of the base 3 corresponding to the bidirectional screw 61. The two ends of the bidirectional screw 61 are rotatably connected to both sides of the movable groove 62. The left and right ends of the upper side of the movable groove 62 are symmetrically provided with clamping plates 63. The lower end of the clamping plate 63 is provided with a limiting slider 64 that can penetrate into the movable groove 62 and slide therewith. The bidirectional screw 61 passes through the corresponding limiting slider 64 and is threadedly connected to it. By rotating the bidirectional screw 61, the two clamping plates 63 can be driven to move closer or further away from each other, thereby realizing the clamping and release of the optical device body 1. It also makes it easy to position the optical device body 1 in the longitudinal middle position of the base 3, which is convenient for the subsequent adjustment structure 5 to make precise adjustment of its longitudinal position.
[0024] For ease of operation, the base 3 is equipped with a knob 65 at one end of the bidirectional screw 61, which can drive the screw to rotate. Through the knob 65, the operator can easily control the rotation of the bidirectional screw 61 to clamp and position the optical device body 1. The threaded connection has a self-locking function, which can ensure the stability of clamping and ensure that the optical device maintains a fixed position during coupling.
[0025] As described above, the BOX-packaged optical device coupling clamping structure of this utility model can effectively achieve precise positioning and reliable clamping of the optical device body 1. When positioning the optical device body 1, the optical device is first placed on the upper side of the base 3. The bidirectional screw 61 is rotated by the knob 65 to initially clamp the optical device in the longitudinal middle position. According to actual needs, the threaded rotating rod 55 is rotated, causing the adjusting plate 51 on the upper side of the base 3 corresponding to the threaded rotating rod 55 to move longitudinally. This, combined with another adjusting plate 51, allows for precise longitudinal position adjustment of the initially positioned optical device body 1. Finally, the positioned optical device body 1 is fixedly clamped by the knob 65. To ensure clamping stability, anti-slip pads can be added to one side of the two clamping plates 63. This clamping structure is reasonably designed and easy to operate, greatly improving the reliability of optical device positioning and the efficiency and success rate of optical device coupling. It is particularly suitable for the production and manufacturing of BOX-packaged optical devices.
