Optical connector
In an optical connector, end faces of a pair of ferrules that hold multiple optical fibers are positioned with two guide pins and butted against each other to connect the optical fibers in the pair of ferrules. The optical connector is provided with an urging member for pushing the end faces against each other. The end faces are ground at an angle. The gap between the guide pins and guide holes, which open at the end faces and into which the guide pins are fitted, is larger than 0.004 mm and smaller than or equal to 0.008 mm. Powder caused by the friction generated when the guide pins are inserted and fitted into the guide holes is greatly reduced. Connection loss does not increase even when frequent connection and disconnection are performed, and cleaning the connector becomes unnecessary.
1. An optical connector in which end faces of a pair of ferrules each holding a plurality of optical fibers are positioned with two guide pins and butted against each other to connect the optical fibers held by the pair of ferrules, the optical connector comprising an urging member for pushing the end faces against each other,
the end faces being ground at an angle, and
the gap between the guide pins and guide holes, which open at the end faces and into which the guide pins are fitted, being larger than 0.004 mm and smaller than or equal to 0.008 mm.
2. The optical connector according to claim 1 , wherein the diameter of the guide pins is set to 0.694±0.001 mm.
3. The optical connector according to claim 1 , wherein the diameter of the guide holes is set to 0.704±0.001 mm.
