OPTICAL CONNECTOR, MANUFACTURING METHOD OF OPTICAL CONNECTOR, AND OPTICAL CONNECTION STRUCTURE

PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical connector which attains compaction of a double-end plug type optical connector and suppression of residual air bubbles in an adhesive for fixing an optical fiber insides.SOLUTION: A manufacturing method of an optical connector comprising plugs in both ends includes: a step for preparing a cylindrical member 10 including a through-hole penetrating an axial direction and an adhesive injection passage 12 extending in a radial direction and having an opening on an outer peripheral surface; an insertion step for coaxially inserting two ferrules 20 to openings in both ends of the through-hole; an injection step for injecting an adhesive from the opening of the adhesive injection passage 12 and filling the inside of the through-hole and the inside of optical fiber insertion holes of the two ferrules 20 with the adhesive; and an insertion step for inserting one optical fiber 30 through the optical fiber insertion holes of the two ferrules 20.SELECTED DRAWING: Figure 2 【課題】両端プラグ型の光接続器のコンパクト化、ならびに、内部に光ファイバを固定するための接着剤への気泡の残存の抑制を図った光接続器の製造方法を提供する。【解決手段】両端にプラグを備える光接続器の製造方法は、軸方向に貫通する貫通孔と、径方向に延び外周面に開口を有する接着剤注入通路１２を備える円筒状部材１０を準備する工程と、貫通孔の両端の開口に対して２本のフェルール２０をそれぞれ同軸状に嵌挿する嵌挿工程と、接着剤注入通路１２の開口から接着剤を注入し、貫通孔の内部および２本のフェルール２０の光ファイバ挿通孔の内部を接着剤で充満する注入工程と、２本のフェルール２０の光ファイバ挿通孔に対して１本の光ファイバ３０を挿通させる挿通工程と、を有する。【選択図】図２
