Heating device for optical-fiber reinforcement, and optical-fiber fusion splicing device

摘要

An optical fiber reinforcing heating device has a base part, to which a first lid part for covering a sleeve accommodation groove for containing a fiber reinforcement sleeve covering a fusion-splicing part of optical fibers is attached so as to be openable and closable. A pair of fiber holders for holding and securing the optical fibers are disposed on both end sides of the first lid part. Each fiber holder has a second lid part which is attached to a fiber container so as to be openable and closable and presses the optical fiber against the fiber container. A switch lever which is movable longitudinally of the sleeve accommodation groove is disposed on the upper face of the second lid part built in with a pin adapted to move in conjunction with the switch lever. A joint hole adapted to engage the pin is formed within the first lid part.

主权项

1. An optical fiber reinforcing heating device for heating and shrinking an optical fiber reinforcement sleeve covering a fusion-splicing part of an optical fiber, the optical fiber reinforcing heating device comprising:
a base part having a sleeve accommodation groove for containing the fiber reinforcement sleeve; an openable and closable first lid part for covering the sleeve accommodation groove; a pair of fiber holders for holding and securing the optical fiber, the pair of fiber holders having openable and closable second lid parts, arranged on both end sides of the sleeve accommodation groove, for pressing the optical fiber; and switch means for switching between a state of opening or closing the first lid part and one of the second lid parts together and a state of opening or closing the first lid part and the one of the second lid parts separately.
