  • Publication number: 20190196117
    Abstract: An optical connector ferrule comprising a first end, a second end, and an outer surface extending between the first and second ends is disclosed. The optical connector ferrule comprises an opening; an introducing hole which extends from the opening to the first end; optical fiber holes which pass through from a tip portion of the introducing hole to the first end; and a window which opens to the outer surface and is connected to the introducing hole, and into which an adhesive is injected. A first opening of the window closer to the outer surface is larger than a second opening of the window closer to the introducing hole. An inner wall of the window includes a first surface provided in the peripheral direction of the inner wall, and the first surface is positioned closer to the introducing hole with respect to the outer surface, and faces the outer surface.

  • Publication number: 20190179087
    Abstract: An optical connector ferrule has a pair of end faces, a plurality of fiber holding holes, and a fiber introduction space having an opening at one end face, communicating with the plurality of fiber holding holes, and receiving the plurality of optical fibers collectively. An inner surface defining the fiber introduction space includes a fiber supporting surface having a plurality of guide grooves formed in such a way as to extend individually from ends of the plurality of fiber holding holes towards the one end face and a pair of first inner lateral surfaces extending individually from both ends of the fiber supporting surface in the second direction. A space between the pair of inner lateral surfaces expands gradually as further away from the fiber supporting surface.

  • Patent number: 9958620
    Abstract: An optical fiber with a connector includes a first connector and a plurality of optical fibers attached to the first connector. The first connector includes: at least one fiber-shaped member; and a ferrule including a first end surface and a second end surface arranged in a first direction, and a holding portion holding the optical fibers and the fiber-shaped member. In the holding portion, a plurality of fiber insertion holes extending from the first end surface in the first direction is formed such that the optical fibers and the fiber-shaped member are insertable thereinto. One end of the optical fiber and one end of the fiber-shaped member are held by the holding portion in a state of being inserted into the fiber insertion hole. The optical fiber extends to the outside of the ferrule. The other end of the fiber-shaped member is located inside the ferrule.
