Cable gripping device and optical fiber connector

Abstract

A cable gripping structure for securing an optical fiber cable in an optical fiber connector possesses a base part and a pair of support walls disposed opposite one another on the base part, and blade parts for gripping the optical fiber cable are disposed on the pair of support walls, at the tip ends thereof and separated from the bases of the support walls.

1 . A cable gripping structure for securing an optical fiber cable in an optical fiber connector, comprising:
 a base part; and   a pair of support walls disposed opposite one another on the base part; and   blade parts for gripping the optical fiber cable being disposed on the pair of support walls at tip ends thereof and separated from bases of the support walls.   
     
     
         2 . The cable gripping structure of  claim 1 , wherein:
 the blade parts can grip a first cable, as well as a second cable in which a dimension of a long side or a short side in cross-section thereof is smaller than that of the first cable; and   a length dimension of the blade parts is equal to or greater than the dimension of the long side in cross-section of the second cable, and is less than the dimension of the long side in cross-section of the first cable.   
     
     
         3 . The cable gripping structure of  claim 1 , wherein the pair of support walls comprise a thin part in which a wall thickness formed toward the tip end of the support wall is small, and a thick part in which a wall thickness formed toward the base end of the support wall is greater than that of the thin part. 
     
     
         4 . The cable gripping structure of  claim 3 , wherein a boundary part between the thin part and the thick part is formed between the base of the support wall and the blade part. 
     
     
         5 . An optical fiber connector into which an end of an optical fiber cable is installed, the optical fiber connector comprising:
 a connector body in which a mounting part is formed for mounting the optical fiber cable; and   a cover part that couples with the mounting part;   the mounting part being formed by at least one surface of a back end portion of the connector body being notched out; and   the cover part comprising the cable gripping structure of  claim 1 , and being disposed to be rotatable relative to the mounting part so as to cover the mounting part.   
     
     
         6 . The optical fiber connector of  claim 5 , wherein:
 a floor surface is provided in the mounting part opposite the tips of the support walls in the state with the cover part covering the mounting part; and   a pressing part, capable of pressing the optical fiber cable, is provided in the floor surface protruding from the floor surface and located in between the pair of support walls in the state with the cover part covering the mounting part.   
     
     
         7 . The optical fiber connector of  claim 5 , wherein a protrusion is provided in the cover part between the pair of support walls, protruding from the base ends toward the tip ends thereof. 
     
     
         8 . The optical fiber connector of  claim 6 , wherein a protrusion is provided in the cover part between the pair of support walls, protruding from the base ends toward the tip ends thereof. 
     
     
         9 . The cable gripping structure of  claim 2 , wherein the pair of support walls comprise a thin part in which a wall thickness formed toward the tip end of the support wall is small, and a thick part in which a wall thickness formed toward the base end of the support wall is greater than that of the thin part. 
     
     
         10 . The cable gripping structure of  claim 9 , wherein a boundary part between the thin part and the thick part is formed between the base of the support wall and the blade part.
