Claims

[Scope of utility model registration request]

In an optical fiber connector connected to an optical fiber cable in which the fiber core wire is sequentially covered with an internal insulator, a reinforcing member, and an outer jacket, a sleeve having a thin hole through which the fiber core wire is inserted;
A metal inner cylinder having a hole into which the sleeve is tightly fitted at one end and into which the internal insulator is inserted at the other end; a hole into which one end of the inner cylinder is press-fitted; a ferrule having a thin hole into which the fiber core wire protruding from the tip of the sleeve is inserted; the sleeve and the ferrule protruding from the other end of the inner cylinder and having an outer circumference where the sleeve is located are caulked; The fiber core wire inserted into the sleeve is crimped and fixed, and the inner insulator inserted into the inner cylinder is crimped and fixed by caulking the outer periphery of the other end of the inner cylinder, and further the outer periphery of the inner cylinder is crimped and fixed. An optical fiber connector, characterized in that the reinforcing member placed over the inner cylinder is crimped and fixed to the outer circumferential part of the inner cylinder using a crimping ring.
