Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection, in particular to an optical fiber connection mechanism. Background Art

[0002] Fiber optic connection devices, commonly known as fiber optic connectors, are an indispensable component of fiber optic communication systems. They are mainly used to connect two fiber optic cables together to achieve data transmission between them. There are many types of fiber optic connectors, each with its specific application scenarios and characteristics. There are two electrodes in the fusion splicer, located on both sides of the optical fiber. When a high voltage is applied, an arc is generated between the electrodes to heat the end face of the optical fiber. When the optical fibers on both ends are heated to the melting point, they melt and fuse together.

[0003] During the fusion splicing process, ensuring the flatness of the optical fiber end face and the precise alignment of the end faces are important guarantees for ensuring the signal quality transmission after fusion splicing. Therefore, it is necessary to cut the fiber in advance before docking, and during the docking process, it is necessary to manually ensure that the optical fiber end face is aligned and placed between the electrodes to perform accurate fusion splicing operations. The overall operation is relatively troublesome, and manual alignment will cause position deviations because the optical fiber is too small. Utility Model Content

[0019] The fixing assembly includes a wire groove 31 and a pressure cover 33. The wire groove 31 is opened at the center position of the upper end of the bearing block 3. The pressure cover 33 is installed above the bearing block 3. A pair of telescopic grooves 32 are opened on the bearing block 3 and the pressure cover 33. A pair of telescopic rods 34 are fixed to one side of the bottom of the pressure cover 33. The bottom of the telescopic rods 34 is slidably connected in the telescopic groove 32. A fixing spring 35 is fixed between the side wall of the telescopic groove 32 and the bottom of the pressure cover 33. The through hole 61 is located in the positioning plate 6 and is a funnel-shaped structure. The opening diameter of the side away from the positioning plate 6 is larger than the opening diameter of the side close to the positioning plate 6. There is an opening structure above the through hole 61.

[0020] A driving groove 8 is opened at the bottom of the limiting groove 21, and a driving block 81 is fixed at the bottom of the supporting block 3. The driving block 81 is slidably connected in the driving groove 8. A bidirectional screw rod 83 is rotatably connected in the driving groove 8. The bidirectional screw rod 83 passes through the driving block 81 and is threadedly connected to the driving block 81. A driving box 84 is fixed on the outside of the welding base 2, and a servo motor that drives the bidirectional screw rod 83 to rotate is fixed in the driving box 84.

[0021] Working principle: First, connect the entire device to an external power source, then fix the optical fiber on the supporting block 3, and the end portion extends out of the supporting block 3. At this time, the supporting block 3 slides to the specified position so that the end portion extends out between the mounting grooves 4. The cutting blade 41 and the pad 42 are driven by the telescopic cylinder 45 to slide toward the adjacent side, so that the end portion of the optical fiber can be cut to ensure that the end portion is neat, and the synchronous reverse sliding of the supporting block 3 can ensure that the length of the optical fiber end portion extending out of the supporting block 3 is the same. During the continuous sliding process of the supporting block 3, until it abuts against the positioning plate 6, the optical fiber can pass through the perforation 61 and be located between the electrode plates 5. At this time, it is only necessary to ensure that the length of the optical fiber extending out of the supporting block 3 is the same as the length from the positioning plate 6 to the center of the electrode plate, so as to ensure that the end portion of the optical fiber is accurately aligned, and the funnel-shaped perforation 61 can be used to avoid sagging of the optical fiber end portion. The positioning deviation is corrected, and then the welding operation is performed. Finally, the dissolved optical fiber is pulled out from the limit groove 21. The whole process is simple to operate and reduces the risk of errors caused by manual docking. When fixing the optical fiber, the end of the optical fiber can be inserted into the wire groove 31, and the fixing spring 35 is pulled down to make the pressure cover 33 squeeze the optical fiber downward to complete the fixing operation. When the supporting block 3 is sliding, the servo motor in the drive box 84 can be used to drive the bidirectional screw rod 83 to rotate, and then drive the drive block 81 to slide in the opposite direction synchronously, and finally drive the drive block 81 to slide in the opposite direction synchronously. Therefore, while ensuring that the end of the optical fiber extends out of the supporting block 3 by the same length, it can be ensured that its end is connected at the position of the electrode sheet 5. During the cutting process, the collection box 44 at the bottom of the pad 42 will move to the bottom of the cutting blade 41 to collect and process the cut optical fiber.
