Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of squeeze polarization controllers, in particular to a mini squeeze polarization controller. Background Art
[0002] The squeeze polarization controller can convert an optical signal of any input polarization state into any desired polarization state by squeezing and twisting the optical fiber. It can be directly applied to the optical fiber system to control the polarization state of light. It has a wide range of applications in the field of device testing, optical fiber sensing and development and research. When using the existing squeeze polarization controller, first open the baffle and loosen the squeeze block, pass the optical fiber through the wire slot and the squeeze block in turn, and then tighten the squeeze block to close the baffle to form a limiting effect on the optical fiber, and then manually deflect the deflection block to form a polarization effect on the optical fiber by squeezing. The polarization degree of the optical fiber can be changed by changing the deflection angle, and then the locking nut is turned to fix it. The traditional squeeze polarization controller has a loose structure and is not compact enough. It cannot accurately limit the optical fiber according to the diameter of the optical fiber. The deflection block needs to be manually deflected to change the polarization effect. It does not have a self-locking function and has a large error. For this reason, we propose a mini squeeze polarization controller. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are: the mini squeeze polarization controller has the following advantages:
[0014] 1. Reverse knob 1 to drive screw 1 to rotate. The extrusion block will move to the left as screw 1 rotates, and the stabilizing spring is compressed. At this time, the gap between the deflection block and the extrusion block becomes larger. The stabilizing slide column and the stabilizing spring can make the extrusion block move up more smoothly. The optical fiber passes through the clamping block, the wire slot and the extrusion block in turn. Then, turn knob 1 forward to drive screw 1 to rotate, and the extrusion block moves to the right. The stabilizing spring slowly rebounds. The stabilizing slide column and the stabilizing spring can make the four corners of the extrusion block more evenly stressed to prevent the accuracy of optical fiber polarization from being affected by uneven force. Then, turn knob 2 forward to drive screw 2 to rotate. As screw 2 rotates, the limit frame also moves downward. As the limit frame moves downward, the two clamping blocks on the same side move inward synchronously until the lower end of the limit frame and the inner wall of the clamping block both contact the surface of the optical fiber. At this time, the optical fiber forms a limit. For optical fibers of different diameters, only the height of the limit frame needs to be changed to quickly and accurately limit the position. Accurate limit can be formed for optical fibers of different diameters according to actual conditions.
[0015] 2. The single-chip microcomputer controls the operation of the drive motor. The output shaft of the drive motor drives the worm to reverse, and the worm wheel also reverses, driving the shaft and gear to rotate. The deflection block then rotates to the right, squeezing the optical fiber to form a polarization effect on the optical fiber. The greater the degree of deflection of the deflection block to the right, the stronger the polarization effect. The transmission is carried out through the worm and worm wheel, and has a self-locking effect. The polarization degree of the optical fiber is changed by the drive motor, which improves the accuracy of the optical fiber polarization. The polarization degree of the optical fiber is automatically changed by the motor, and it also has mechanical self-locking, which improves the accuracy of the optical fiber polarization.

[0024] The working principle of the mini squeeze polarization controller provided by the utility model is as follows: when the mini squeeze polarization controller is working, the single chip computer 3 controls the driving motor 471 to operate, and the output shaft of the driving motor 471 drives the worm 472 to rotate forward. Because the worm 472 is meshed and connected with the worm wheel 473, the worm wheel 473 also rotates forward, driving the rotating shaft 461 to rotate, and the gear 462 also rotates accordingly. Because the gear 462 and the tooth groove 463 are integrally meshed and connected, the deflection block 41 will deflect to the left. At this time, the clamping area formed between the deflection block 41 and the squeezing block 42 is aligned with the wire groove 484, and the reverse knob is turned to drive the screw rod. 45 rotates, because the lower end of the outer surface of the screw rod 45 is connected to the inner middle thread of the extrusion block 42, the extrusion block 42 will move to the left with the rotation of the screw rod 45, and the stabilizing spring 44 is compressed. At this time, the gap between the deflection block 41 and the extrusion block 42 becomes larger, and the stabilizing slide column 43 and the stabilizing spring 44 can make the extrusion block 42 move up more smoothly. The optical fiber is passed through the clamping block 481, the wire groove 484 and between the deflection block 41 and the extrusion block 42 in sequence, and then the knob 1 is turned forward to drive the screw rod 45 to rotate, the extrusion block 42 moves to the right, and the stabilizing spring 44 slowly rebounds. The stabilizing slide column 43 and the stabilizing spring 44 can The force on the four corners of the extrusion block 42 is made more uniform to prevent the accuracy of the optical fiber polarization from being affected by uneven force. Then, the second knob is turned forward to drive the second screw rod 486 to rotate. Because the second screw rod 486 is threadedly connected to the middle of the interior of the mounting block 485, the lower end of the outer surface of the second screw rod 486 is rotatably connected to the middle of the interior of the limit frame 483. Therefore, as the second screw rod 486 rotates, the limit frame 483 also moves downward. As the limit frame 483 moves downward, the two clamping blocks 481 on the same side move inward synchronously until the lower end of the limit frame 483 and the inner side wall of the clamping block 481 both contact the surface of the optical fiber. At this time, the optical fiber forms a limit. For optical fibers of different diameters, it is only necessary to change the height of the limit frame 483 to quickly and accurately limit the position. At this time, the single-chip computer 3 controls the driving motor 471 to operate, and the output shaft of the driving motor 471 drives the worm 472 to reverse, and the worm wheel 473 also reverses accordingly, driving the rotating shaft 461 and the gear 462 to rotate, and the deflection block 41 rotates to the right accordingly, squeezing the optical fiber to form a polarization effect on the optical fiber. The greater the degree of right deflection of the deflection block 41, the stronger the polarization effect. The transmission is carried out through the worm 472 and the worm wheel 473, and has a self-locking effect. The polarization degree of the optical fiber is changed by the driving motor 471, thereby improving the accuracy of the optical fiber polarization.
