Technical Field

[0001] This utility model relates to the field of optical fiber fusion splicer technology, specifically to an automatically adjustable electrode structure for an optical fiber fusion splicer. Background Technology

[0002] A fiber optic fusion splicer is a device that uses the high temperature generated by an electric arc from a pair of electrodes to melt the end faces of two cleaved optical fibers. Simultaneously, it employs the collimation principle to smoothly advance the two ends together, achieving coupling of the fiber mode fields. It is widely used in communication engineering construction, maintenance, and communication equipment manufacturing. During operation, the distance between the electrode needles significantly affects the splicer's discharge capability. However, in existing technologies, the electrode structure used in fiber optic fusion splicers is typically a fixed design, and the distance between the electrode needle tips cannot be adjusted, which to some extent limits the splicing capability of fiber optic fusion splicers for fibers with different cladding diameters. Therefore, this application proposes an automatically adjustable electrode structure for fiber optic fusion splicers. Utility Model Content

[0027] In summary: When using the automatic electrode adjustment structure of this fiber optic fusion splicer, the fiber optic fusion splicer electrode needles 4 are fixed to the electrode base 3 using conventional techniques. When the position between the two electrode needles needs to be changed, the linear motor 9 operates, driving the drive rod 13 to move. The drive rod 13, through the connecting rod 12 and the push seat 14, drives the guide seat 15 to move. The guide seat 15, through the electrode base 3, drives the fiber optic fusion splicer electrode needles 4 to move, thereby adjusting the distance between two adjacent fiber optic fusion splicer electrode needles 4. During the position adjustment process of the fiber optic fusion splicer electrode needles 4, the guide component guides the guide seat 15, the limiting plate 10 guides the drive rod 13, and the limiting device 7 monitors the movement distance of the fiber optic fusion splicer electrode needles 4 in real time. When the fiber optic fusion splicer electrode needles 4 have moved into position, the controller of the automatic electrode adjustment structure controls the linear motor 9 to stop working, and the position of the fiber optic fusion splicer electrode needles 4 is fixed, facilitating the operation of the fiber optic fusion splicer. When the fiber optic fusion splicer electrode needle 4 needs to be reset, the controller controls the linear motor 9 to run in reverse. The linear motor 9 drives the drive rod 13 to move in reverse. The drive rod 13 drives the guide seat 15 to move in reverse through the connecting rod 12 and the push seat 14. The guide seat 15 drives the fiber optic fusion splicer electrode needle 4 to move in reverse through the electrode seat 3. The fiber optic fusion splicer electrode needle 4 can be reset. In this process, the rebound force of the tension spring 5 can increase the reset speed of the fiber optic fusion splicer electrode needle 4.
