  • Publication number: 20210173154
    Abstract: An optical connector includes: a ferrule including a guide pin hole, a plurality of fiber holes lined up in a width direction of the optical fiber, and an inclined end face; a housing in which the ferrule is retractably housed; and an application part that applies an upward force to the ferrule in an upward/downward direction when the optical connector connects with a counterpart connector in a connecting/disconnecting direction. The upward/downward direction is a height direction of the optical connector and is orthogonal to both the connecting/disconnecting direction and the width direction. The inclined end face projects upward toward the counterpart connector.

  • Publication number: 20210080656
    Abstract: An optical connector includes: a housing that retractably accommodates a ferrule; a spring that is accommodated in the housing to press the ferrule to a front side; and an engaging member connected to one end of the spring, fixed to the housing by engaging with the housing, and including a pair of arm parts arranged to sandwich the spring. When a direction perpendicular to a direction in which the spring presses the ferrule and to a direction in which the pair of arm parts is lined up is an up-down direction, window parts are arranged on both sides in the up-down direction of the housing. The engaging member includes: claw parts that are provided on an upper and a lower side of the pair of arm parts to engage with the window parts; and deformation parts that allow the claw parts to be displaced in the up-down direction.

  • Patent number: 9891392
    Abstract: An optical connector of the disclosure includes: an optical connector body including a housing that houses a ferrule, and a coupling that is movable relative to the housing, the optical connector body being employed to release a latched state by moving the coupling rearward relative to the housing; and a pull member including a pull operation part that is located rearward of the coupling. The pull member includes a pair of side plate parts to be respectively arranged along the side surfaces of the coupling. Each side plate part includes an inner projection that projects inward from an inner surface. The coupling includes a recessed engagement part. The inner projection of the pull member engages with the engagement part of the coupling. When the pull operation part of the pull member is pulled rearward, the coupling is moved rearward relative to the housing by the inner projection of the pull member.

  • Patent number: 9535222
    Abstract: A plug-side optical connector, including: a plug-side coupling mechanism and a ferrule. The plug-side coupling mechanism is to be coupled to a coupling mechanism of another optical connector, the other optical connector being on receptacle side and being for being coupled with the plug-side optical connector. The plug-side coupling mechanism includes: a reference section to which the coupling mechanism of the other receptacle-side optical connector is to be hooked; and an inserted section that is to be inserted into a cylindrical main body of the coupling mechanism on the receptacle side. The ferrule is accommodated inside the inserted section. When a direction in which the optical connector is attached or detached is defined as a front-rear direction and a side of the receptacle-side optical connector is defined as front, a distance in the front-rear direction from the reference section to a front edge of the inserted section is 7.0 mm or more.
