Abstract

PURPOSE:To reduce the size of an optical connector plug while maintaining its strength by forming the inside of a tip part of an insertion guide for the optical connector plug by a reinforcing pipe and forming its outside by a composite material of resin molding arts. CONSTITUTION:The inside and outside of the tip part of the insertion guide 4 for the optical connector plug A are respectively constituted of the reinforcing pipe and the composite structure of the resin molding parts. Thereby, the thickness of the reinforcing pipe 5 can be easily set up <=0.2mm which can not be easily obtained by resin molding or die-cast metal molding and the resin molding is utilized for a complex shape part such as a groove part 6 to effectively form the insertion guide 4. Since the reinforcing pipe 5 is constituted of a high strength material such as metal or ceramics, the crush strength or deformation resisting force of the insertion guide 4 is improved and the coupling strength of the plug with a claw part 11 of an optical connector adapter can be also improved.
