  • Publication number: 20220187554
    Abstract: A plug connector is attachable with an optical fiber cable and is connectable with a receptacle connector. The receptacle connector comprises a receptacle shell. The plug connector comprises a front holder, a cable holding portion, a rear holder and a coupling member. The front holder is made of metal. The front holder is mated with the receptacle shell when the plug connector is connected with the receptacle connector. The cable holding portion is made of metal. The cable holding portion is configured to hold the optical fiber cable. The rear holder guards the cable holding portion. The rear holder comprises, at least in part, a thermal insulating portion made of non-metal material. The coupling member couples the front holder and the rear holder with each other. Each of the coupling member and the front holder is in contact with the rear holder only on the thermal insulating portion.

  • Patent number: 11336056
    Abstract: A connector device comprises a connector and a mating connector. Under a mated state where the connector and the mating connector are mated with each other, the mating connector is positioned forward of the connector in a front-rear direction. The connector comprises at least one supporting portion, at least one lock portion and a receiving portion. The mating connector has at least one mating lock portion and an abutment portion. At least one of the lock portion and the mating lock portion has an intersecting surface which intersects with both the front-rear direction and a perpendicular direction. Under the mated state, the abutment portion is positioned forward beyond the receiving portion in the front-rear direction and is brought into abutment against the receiving portion by a rearward force so that a rearward movement of the abutment portion beyond the receiving portion is regulated by the receiving portion.

  • Patent number: 11249258
    Abstract: A connector includes a cable holding portion, a first holding member having a first male screw portion and a first guide portion, an optical connector, an optical module, a second holding member having a second male screw portion and a second guide portion, and a coupling nut having a female screw portion. In cooperation with each other, the first and second guide portions allow a relative movement of the first holding member with respect to the second holding member in the front-rear direction while regulating a relative movement of the first holding member with respect to the second holding member in a circumferential direction about an axis parallel to the front-rear direction. Relative positions of the first holding member and the second holding member in the front-rear direction are maintained by the female screw portion being meshed with both of the first and the second male screw portions.

  • Publication number: 20210405300
    Abstract: This connector (100) is provided with a locking member (200), a receiving part (192), an additional elastic part (420) and a pressing member (440). The locking member (200) comprises a supporting part (220) and a locking part (250). A mating-side connector (600) is provided with a mating-side locking part (660) and an abutting part (632). In the fitted state, the locking part (250) applies backwards force on the mating-side locking part (660) with the elasticity of the supporting part (220). The abutting part (632) is positioned in front of the receiving part (192), is pressed against the receiving part (192), and is restricted from moving backwards by the receiving part (192). When the pressing member (440) is in a first position, the additional elastic part (420) is interposed between the supporting part (220) and the pressing member (440), presses down the supporting part (220), and maintains pressing of the locking part (250) against the mating-side locking part (660).

  • Patent number: 10754090
    Abstract: A plurality of optical fiber groups are housed in an optical fiber cable and which of the optical fiber groups optical fibers, which constitute the optical fiber groups, belong to can be identified depending on a covering of the optical fibers. Each of optical connectors (plug, receptacle) which are respectively attached to both ends of the optical fiber cable has regions, in which insertion holes in which the optical fibers are inserted and fixed one by one are formed to be arranged in a predetermined interval, in the same number as the number of the optical fiber groups, and even though the optical fibers in one optical fiber group are inserted and fixed in the insertion holes in an identical region, an arrangement order of the optical fibers in the region of the optical connector provided on one end is not maintained as an arrangement order of the optical fibers in the region of the optical connector provided on the other end.

  • Publication number: 20200200980
    Abstract: An optical connector includes a connector housing that holds a ferrule such that the ferrule is allowed to move backward along a connecting direction, and the optical fiber in the connector housing has at least one loop element each having a tangential line along the connecting direction and a pair of tangential line portions connected to the at least one loop element and is held in such a manner as not to prevent a radius of curvature of the at least one loop element from becoming larger as the ferrule moves backward along the connecting direction.

  • Patent number: 10320121
    Abstract: A connector-incorporating plug which has a built-in connector in a tube-shaped barrel and in which a coupling is mounted at an outer circumference of the barrel at a front end thereof so as to be movable along a center axis of the barrel includes a C ring mounted, in a detachable manner, in a groove formed on the outer circumference of the barrel and restricting movement of the coupling toward a rear end of the barrel. The C ring is made of a resin material. An outer circumferential side portion of an intermediate portion of a C shape of the C ring protrudes back and forth in the thickness direction thereof to be thick.

  • Patent number: 10295764
    Abstract: A plug connector is provided with a photoelectric conversion portion, a first electric connector and a first lock portion. The first electric connector inputs and outputs electric signals into and from the photoelectric conversion portion. The first lock portion and the first electric connector are apart from each other by a first distance. A receptacle connector is provided with a second lock portion and a second electric connector. When the plug connector and the receptacle connector are mated with each other, the second lock portion engages with the first lock portion, and the second electric connector is connected to the first electric connector. The second lock portion and the second electric connector are apart from each other by a second distance. A difference between the first distance and the second distance is equal to or less than an effective contact length between the first electric connector and the second electric connector.
