Optical fiber cutting blade, optical fiber cutting device and method of cutting off the optical fiber, as well as component for peeling the coating and breaking the optical fiber and method of peeling the coating and breaking the optical fiber

Abstract

A component for peeling the coating and breaking the optical fiber, which comprises the first member made of resin material including a groove portion enabling to receive a coated optical fiber, an optical fiber cutting blade and a coat removing blade integrally formed within the groove portion, and a breaking portion in an intermediate portion, and the second member made of resin material including a groove portion corresponding to the groove portion in the first member enabling to receive a coated optical fiber, a coat removing blade corresponding to the coat removing blade in the first member, and a breaking portion in an intermediate portion corresponding to the breaking portion in the first member.

What is claimed is: 
     
         1 . An optical fiber cutting blade comprising a base made of resin material, and a blade made of resin material integrally formed with said base, wherein
 the resin material of the blade comprises a glass filler and is deformable by pressing the blade onto an optical fiber.   
     
     
         2 . The optical fiber cutting blade according to  claim 1 , wherein said resin material comprises epoxy or pps (polyphenylene sulfide) based synthetic-resin and at least 60% of glass filler. 
     
     
         3 . The optical fiber cutting blade according to  claim 1 , wherein an angle of a tip portion of said blade is within a range of from 10 to 45 degrees. 
     
     
         4 . An optical fiber cutting device including: a rectangular base made of resin material having a groove portion formed in a longitudinal direction thereof which receives an optical fiber, and a blade made of resin material integrally formed with the base in perpendicular to the groove portion, wherein
 the resin material of the blade comprises a glass filler and is deformable by pressing the blade onto an optical fiber.   
     
     
         5 . The optical fiber cutting device according to  claim 4 , wherein the groove portion comprises a flat bottom face, and both slanted side faces which become wide from the bottom face toward a surface of the base, and the blade is positioned within the groove portion and a tip end of the blade is formed to be approximately same height as the surface of the base. 
     
     
         6 . The optical fiber cutting device according to  claim 5 , wherein an angle of a tip portion of the blade is within a range of from 10 to 45 degrees. 
     
     
         7 . A method of cutting off an optical fiber comprising the steps of:
 pressing a blade of resin material integrally formed with a base of the resin material onto the optical fiber until the blade itself is deformed to scratch the optical fiber, the resin material of the blade comprising a glass filler;   adding a tensile force to a prescribed portion of a scratched optical fiber; and   bending in an opposite direction to a scratch to cut off the optical fiber.   
     
     
         8 . The method according to  claim 7 , wherein the optical fiber comprises a coated optical fiber. 
     
     
         9 . The method according to  claim 7 , wherein the optical fiber comprises an optical fiber with a coating removed.
