Claims

[Scope of Claim for Utility Model Registration] (1) An optical connector sleeve in which an inner sleeve with a smaller inner diameter is fitted into an outer split sleeve with a larger inner diameter to align and hold ferrules with different outer diameters, A sleeve for an optical connector, characterized in that the outer diameter of the inner sleeve is formed to be approximately the same as the inner diameter of the outer split sleeve, and a stop collar is provided protruding from one end of the inner sleeve. (2) The sleeve for an optical connector according to claim 1, wherein the inner sleeve is a split sleeve. (3) The outer split sleeve and inner split sleeve are
3. The sleeve for an optical connector according to claim 2, wherein the inner diameter shape is not a perfect circle before the ferrule is inserted, but the inner diameter shape becomes a perfect circle when the ferrule is inserted. (4) The inner sleeve is formed with an outer diameter equal to the inner diameter of the outer split sleeve, and a ring-shaped member having approximately the same outer diameter as the outer split sleeve is press-fitted or glued onto one end of the inner sleeve to form a stop collar. 3. The sleeve for an optical connector according to claim 1, wherein the sleeve is formed with a protruding portion.
