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

摘要

An optical fiber reinforcing heating device 6A is equipped with a base part 12, while the base part 12 is 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 holders 19 that holds and clamps fusion-spliced optical fibers 3 are disposed on both end sides of the sleeve accommodation groove. A lid part 23 that covers the fiber accommodation groove 13 is attached openably and closably to the base part 12 through a rotary axis. A protector 24 for windbreak and heat insulation is joined to the lid part 23 through a rotary axis 25. The protector 24 is a member for preventing winds from entering the sleeve accommodation groove from a gap between a side wall of the base part 12 and the lid part 23.

主权项

1. An optical fiber reinforcing heating device for heating and shrinking a fiber reinforcement sleeve covering a fusion-splicing part of optical fibers, the optical fiber reinforcing heating device comprising:
a base part having a sleeve accommodation groove that contains the fiber reinforcement sleeve; a heater that heats the fiber reinforcement sleeve contained in the sleeve accommodation groove; a pair of fiber clamping parts that clamp the optical fibers, which are arranged on both end sides of the sleeve accommodation groove; a lid part attached openably and closably to the base part, the lid part covering the sleeve accommodation groove; and a protector, joined to the lid part, which prevents winds from entering the sleeve accommodation groove in a state where the lid part is closed wherein the protector is joined to the lid part such as to descend along a side face of the base part when the lid part is opened.
