claims of fusion splicer

Abstract

The optical fiber fusion splicer device comprises a pair of electric discharge electrodes provided opposed to each other along a predetermined axis, a conductor electrode disposed on one side with respect to a plane with the predetermined axis contained therein, and section for generating electrostatic attraction in the direction tending from the above-described plane toward the one side, between the conductor electrode and the electric discharge path produced between the electric discharge electrodes. The means for generating electrostatic attraction is connected to the conductor electrode. This fusion splicer fusion-splices together the end portions of optical fibers disposed on the other side with respect to the above plane by electric discharge produced between the electric discharge electrodes.
