Abstract:
An optical fiber fixing structure for fixing a coated optical fiber to an optical fiber fixture, the optical fiber fixing structure characterized in that the optical fiber fixture is formed with an optical fiber insertion hole penetrating from a tip end side thereof to a back end side and an opening communicating from a side of the optical fiber fixture to said optical fiber insertion hole, wherein the coated optical fiber is inserted into said optical fiber insertion hole, an optical fiber fixing component having optical fiber clamping parts facing each other is inserted and fit to said opening as clamping tip end sides of said optical fiber clamping parts are faced to a side of said coated optical fiber, the coated optical fiber is clamped from both sides by the optical fiber fixing component as an outer periphery of said coated optical fiber is clamped between inner wall surfaces of the optical fiber clamping parts facing each other of said optical fiber fixing component, outer surfaces of the optical fiber clamping parts of said optical fiber fixing component are pressure welded with inner surfaces of the opening of said optical fiber fixture, and said coated optical fiber is fixed and prevented from falling off from said optical fiber fixture.
