Abstract:
1. An optical connector for splicing a rear end of a pre-assembled optical fiber that has been previously mounted within an optical ferrule in a connector body with a tip of a second optical fiber that is to be inserted into the connector body, the optical connector comprising: the connector body; and an anchor mechanism for anchoring the second optical fiber to the connector body, wherein: the connector body includes the optical ferrule and a connecting mechanism provided at a rear end side, opposite to a connecting end surface of the optical ferrule; the connecting mechanism includes an optical fiber alignment hole in which the pre-assembled optical fiber extending from the rear end side of the optical ferrule is inserted, the rear end of the pre-assembled optical fiber and a front end of the second optical fiber being aligned and spliced with each other in the optical fiber alignment hole; the anchor mechanism includes a holder for holding the second optical fiber, and a connecting portion which anchors the holder to the connector body; at a position where the holder is anchored to the connector body and the rear end of the pre-assembled optical fiber and the second optical fiber are aligned and spliced with each other, the length of the second optical fiber from the holder to the tip is longer than the distance from the holder to the rear end of the pre-assembled optical fiber; and the rear end of the pre-assembled optical fiber has a curved convex end surface or an end with a diameter-reducing portion, and is PC-connectable to the tip of the second optical fiber.
