Problems solved by technology

[0003] However, for example, some applications of high-power fiber lasers require the fiber diameter to be over 1mm, and ordinary fusion splicing equipment will not be able to thermally fuse 200um optical fibers. The existing technologies for thermally melting large fiber diameters are mainly resistance wire or laser heating. diameter of the optical fiber, the dielectric properties of the optical fiber material can make the arc discharge region 3 bend around the optical fiber instead of wrapping the entire circumference of the optical fiber 2, such as figure 2 shown; but the above method may cause uneven heating of the fiber and lead to fusion splicing failure

Abstract

The invention provides a four-electrode welding device for a fiber splicer; the four-electrode welding device comprises four electrode rods arranged in a rectangular form, center lines of the four electrode rods are coplanar, extension lines of the center lines of the four electrode rods intersect at a point, and the tips of all the electrode rods point to the point; after the four electrode rods are electrified, an arc discharge zone is formed among the tips of the four electrode rods. The arc discharge zone generated by the four-electrode welding device can splice a thick fiber or multiple fibers, and can withhold slight fluctuations from outside; the four-electrode welding device is disposed in partial or complete vacuum; compared with the prior art, the four-electrode welding device, with convection eliminated (or diminished) and an enhanced plasma field isothermal range provided, has the advantages that slight upward fluctuations are generated at the premise of rising of heat from plasm (under atmospheric pressure) and may destroy ionic paths among the electrodes, and the destroying may sway or extinguish plasma in air.

Description

technical field [0001] The invention relates to an electrode welding device, in particular to a four-electrode welding device for an optical fiber fusion splicer. Background technique [0002] The optical fiber fusion splicer uses two electrode rods 1 to generate a high-voltage arc to melt the sections of the two optical fibers. At the same time, it uses a high-precision motion mechanism to gently advance the two optical fibers into one. Most optical fibers have a diameter of 80um to 125um (not including the coating layer). Arc discharge region 3 melts the above-mentioned optical fiber 2 cross-section treatment situation as follows figure 1 shown. [0003] However, for example, some applications of high-power fiber lasers require the fiber diameter to be over 1mm, and ordinary fusion splicing equipment will not be able to thermally fuse 200um optical fibers. The existing technologies for thermally melting large fiber diameters are mainly resistance wire or laser heating. d...
