  • Patent number: 9091825
    Abstract: An optical fiber connector includes a ferrule, an inserted optical fiber, an external optical fiber, and a pair of reinforcing members that pinches and reinforces a fusion-spliced portion of the other end portion of the inserted optical fiber and the front end portion of the external optical fiber. The reinforcing members include adhesion layer on the inner surface thereof which comes in contact with the other end portion of the inserted optical fiber and the front end portion of the external optical fiber. The adhesion layer is depressed at the position where the inserted optical fiber and the external optical fiber come in contact with each other so as to closely adhere to the outer circumferential surfaces of the optical fibers in the fusion-spliced portion.

  • Publication number: 20150198773
    Abstract: An optical connector comprises a housing, a regulating portion which is protrudes toward an inner surface of the housing, a ferrule which is secured to an optical fiber and which is accommodated inside the housing so as to be movable. The ferrule includes a base portion and a thinned portion that has a thickness smaller than that of the base portion. If the ferrule moves forward in the butt-connection direction, the regulating portion and the base portion approach each other, so that the regulating portion regulates the movement of the ferrule in the thickness direction. If the ferrule moves backward in the butt-connection direction, the ferrule reaches a position where the thinned portion faces the regulating portion, so that the movement of the ferrule in the thickness direction is not regulated by the regulating portion.
