EFFICIENT HEATING GROOVE FOR OPTICAL-FIBER FUSION SPLICER AND OPTICAL-FIBER FUSION SPLICER

摘要

The present invention discloses a highly efficient heating groove and an optical fiber fusion splicer for an optical fiber fusion splicer. Wherein the heating substrate of the heating groove is a metal thin plate material having a good heat conduction performance and the manufacturing of the heating groove is performed by a thick film silk screen printing process on the outer surface of the thin metal plate heating base material, An advantageous conductor, and a glass protective glaze. Wherein an exothermic resistance is printed on each of the two heating surfaces of the heating groove, the resistance value of each exothermic resistance is 4.7 ± 0.5 Ω, the output density is 10 to 20 W / cm ² , and the exothermic resistance has a temperature coefficient of 1500 Select a resistance material of ± 150 ppm / ° C. The heating groove of the present invention optimizes the material parameters and the resistance distribution method of the exothermic resistance, significantly improves the temperature rise and heat shrinkage effect, and greatly reduces the heat shrinkage time.
