CUTTING DEVICE OF OPTICAL FIBER AND CUTTING METHOD OF OPTICAL FIBER, AND BLADE MEMBER FOR CUTTING OPTICAL FIBER |
摘要 |
<p>An optical fiber cutting device and method, and optical fiber cutting blade member in which excellent workability is obtained by a simple configuration, and a cost reduction can be attained are provided. An optical fiber cutting device 10 includes: clamps 20U, 20L which clamp an optical fiber 11 at both axial sides of a to-be-cut portion to fix the optical fiber 11; a blade member 30 which presses a blade edge 31 against the to-be-cut portion of the optical fiber 11 clamped by the clamps 20U, 20L, to provide an initial flaw 11a; an updating mechanism 40 which updates the position of the blade member 30 so that, during a cutting operation, an unused portion of the blade edge 31 is contacted with the optical fiber 11; a pillow member 50 which presses the optical fiber 11 from the side opposite to the initial flaw 11a provided by the blade member 30, to apply a tensile bending force, thereby breaking the optical fiber 11; and a blade pressure setting spring 32 which urges the blade member 30 toward the optical fiber 11 by a predetermined elastic urging force.</p> |
