  • Patent number: 10983289
    Abstract: The present invention provides an optical connector capable of fixing the tensile strength fibers of the optical cable to the optical connector while keeping the tensile strength sufficiently without sacrificing the easiness of assembling the optical connector. The optical connector The optical connector is configured to be attached to an optical cable having an optical fiber and tensile strength fibers extending along a longitudinal direction of the optical fiber, having: a connector body having a male screw; and a fixing member used for fixing the tensile strength fibers to the connector body, the fixing member having a female screw, wherein the tensile strength fibers are configured to be interposed between the male screw and the female screw and fixed to the connector body when the male screw formed on the connector body and the female screw formed on the fixing member are screwed with each other, and the male screw has a notch extending in a direction crossing a screw thread of the male screw.
