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.

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

An optical fiber reinforcing heating deviceA is equipped with a base part, while the base partis provided with a sleeve accommodation groove that contains a fiber reinforcement sleeve and a heater having a U-shaped cross section, which heats the fiber reinforcement sleeve. A pair of fiber holdersthat holds and clamps fusion-spliced optical fibersare disposed on both end sides of the sleeve accommodation groove. A lid partthat covers the fiber accommodation grooveis attached openably and closably to the base partthrough a rotary axis. A protectorfor windbreak and heat insulation is joined to the lid partthrough a rotary axis. The protectoris a member for preventing winds from entering the sleeve accommodation groove from a gap between a side wall of the base partand the lid part
