Abstract

An optical connector according to the present invention has a ferrule body provided with a fiber positioning hole, a pair of guide holes into which guide pins are inserted, and a connecting end face in which ends of the fiber positioning hole and guide holes open. A chamfer portion equivalent to a part of a surface of a body of revolution is formed at each guide hole on the connecting end face side. Further, the connecting end face is formed at an angle relative to a plane normal to the center axes of the pair of guide holes.

Description

technical field [0001] The invention relates to one of the components of the optical connector, a ferrule for an optical connector for positioning and fixing the end of an optical fiber and a manufacturing method thereof. Background technique [0002] One of methods for connecting optical fiber ends to each other is to make the optical fiber ends into connectors. In optical fiber end connectorization, a part called a ferrule is used to position and fix the ends of optical fibers to facilitate the positioning of mutual ends and maintain the connection state. MT connectors, MPO connectors, and the like are known as connector standards to which ferrules are applied. As such a connector, what is described in JP-A-9-68627 is known. [0003] When splicing optical fibers, the core in the center of the optical fiber needs to be positioned with high precision. In the above-mentioned MT connectors and MPO connectors, etc., guide holes and guide pins are used for mutual positioning. ...
