Manufacturing method of electrode rod, electrode rod and optical fiber fusion splicer including the electrode rod

Abstract

The invention discloses an electrode bar production method. The electrode bar production method mainly includes: producing an electrode bar blank, wherein the electrode bar blank at least comprises a discharge end blank with the perimeter of the outer side face larger than the discharge end of a finished electrode bar; then, subjecting the electrode bar blank to heat treatment so as to obtain an insulation oxide layer by in-situ synthesis; finally, processing the discharge end blank of the electrode bar blank so as to obtain the finished electrode bar. Meanwhile, the invention discloses the electrode bar. One insulation oxide layer obtained by in-situ synthesis is arranged on the outer surface of at least the tip of the electrode bar, and the insulation oxide layer is not arranged on the discharge end which is in an allowed conducting state. The electrode bar production method is low in operation difficulty; the insulation oxide layer of the electrode bar is arranged on the tip of the electrode bar by in-situ synthesis, so that the insulation oxide layer and a basal body are higher in binding force, proneness to coating shedding, instable discharge and the like is avoided, and the problem that the electrode bar needs to be replaced frequently due to the fact that the rear of the electrode bar close to the discharge end is contaminated by fiberglass easily is solved.

Description

technical field [0001] The invention relates to the technical field of optical fiber fusion, in particular to a method for manufacturing an electrode rod used in an optical fiber fusion splicer, the electrode rod, and an optical fiber fusion splicer including the electrode rod. Background technique [0002] Optical fiber fusion splicers are mainly used for the construction and maintenance of optical cables in optical communications. The general working principle is to use a high-voltage arc to melt the sections of the two optical fibers, and at the same time use a high-precision motion mechanism to gently advance the two optical fibers into one, so as to realize the coupling of the optical fiber mode field. Among them, optical fiber fusion is to perform high-voltage and high-frequency discharge on a pair of electrode rods to generate a high-temperature welding arc, thereby melting the end face of the optical fiber. [0003] When optical fiber is welded, the temperature of t...
