Abstract
An optical fiber connector (19) has a connector main body including a first pipe (20) for receiving a fiber (24) inside, and three second pipes (21a) through (21c) for receiving the first pipe (20) inside. With this arrangement, the fiber (24) can be securely held with ease at the center of the connector main body. On this account, it is possible to provide the optical fiber connector (19) in which the fiber (24) is securely held with ease at the center of the connector main body.
Claims18
An optical fiber connector in which a lens is formed at a resin injection portion located at a front end of an optical fiber inserted in a connector main body,
- wherein the connector main body includes a first pipe for receiving the optical fiber inside, and a second pipe for receiving the first pipe inside,
- wherein the lens surface is formed by a dead weight and a surface tension of resin, and
- wherein the lens is shaped taking into account a positioning error of the optical fiber with respect to an outer diameter of the connector.
A method for manufacturing an optical fiber connector in which a lens is formed at a resin injection portion located at a front end of an optical fiber inserted in a connector main body,
- said method comprising:
- a connector forming step of forming the connector main body by inserting a first pipe in a second pipe, wherein the first pipe receives the optical fiber inside, and the second pipe receives the first pipe inside;
- a fiber inserting step of inserting the optical fiber in the first pipe of the connector main body formed in the connector forming step;
- and
- a lens forming step of forming a lens by injecting a light-hardened resin or a thermosetting resin in the resin injection portion.
