Abstract: An elastic member according to an embodiment is an elastic member that biases a ferrule retaining a plurality of optical fibers in a connecting direction. The elastic member is stored in an inner housing that accommodates the ferrule, the elastic member has a space in its inside into which a 16-fiber tape fiber is inserted, and the elastic member is in a noncircular shape in a cross section intersecting with the connecting direction. The elastic member includes a pair of first portions having an outer surface opposite to a pair of inner surfaces in an arc shape of the housing, the inner surfaces being opposite to each other along a first direction intersecting with the connecting direction and a pair of second portions opposite to the tape fiber along a second direction intersecting with both of the connecting direction and the first direction.

Abstract: An optical connector comprises: an inner housing including an engagement recess for engaging an optical adaptor on its surface; a boot connected to a rear side of the inner housing; a first outer housing covering the engagement recess; and a second outer housing covering a part of the first outer housing and provided freely movably in a front-rear direction relative to the first outer housing. When the second outer housing moves frontward, the engagement recess is exposed by the second outer housing and the inner housing moving relative to the first outer housing, and when the second outer housing moves rearward, the engagement recess is exposed by the second outer housing and the first outer housing moving relative to the inner housing.

Abstract: An optical connector 1 is an optical connector connected to an external optical adapter. The optical connector 1 is provided with: an inner housing 3, in a surface of which engaging holes for engaging the optical adapter is provided; a boot 6 connected to the inner housing 3 on a side opposite the optical adapter in a forward/backward direction; and a first outer housing 4 and a second outer housing 5 covering the engaging holes and mounted on the inner housing 3 to be freely movable in the forward/backward direction. As the second outer housing 5 moves backward, the engaging holes of the inner housing 3 are exposed. The second outer housing 5 has cutout parts 5c which are cut out from a back end surface 5f in the forward direction and which a front end part of the boot 6 enters.

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.

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.

Abstract: An optical connector is an optical connector that is connected to another connector in a predetermined connection direction. The optical connector includes a ferrule that includes insertion holes into which guide pins to be connected to another connector are to be inserted; and a pin keeper 20 that is provided on a side of the ferrule opposite to the another connector and includes retaining holes 21 retaining the guide pins inserted into the insertion holes. The pin keeper 20 includes a pair of side portions 22 in which the retaining holes 21 are formed, and a bottom portion 23 that connects end portions of the pair of side portions 22. The retaining holes 21 are formed in a shape in which inside surfaces of the side portions 22 facing each other are notched.

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.
