  • Patent number: 10401577
    Abstract: A multi-core optical fiber connection device comprises a first multi-core optical fiber connector and a second multi-core optical fiber connector. The first multi-core optical fiber connector comprises a first joint unit. The second multi-core optical fiber connector comprises a second joint unit. The second contact receptacle unit comprises a movable jacket and a movable ring. As long as the movable ring is pulled, the first joint unit is pushed by the movable jacket so that the first multi-core optical fiber connector and the second multi-core optical fiber connector are separated from each other, which achieves the effect that the first multi-core optical fiber connector and the second multi-core optical fiber connector are quickly connected with each other and separated from each other by one-hand operation.

  • Patent number: 10345536
    Abstract: The present invention discloses an optical fiber connector, comprising: a housing, a ferrule installed within said housing; an end sleeve, connecting to the rear end of said housing; and an optical cable clamp, installed by insertion within said end sleeve, being provided for the purpose of clamping an optical cable. Said optical cable is secured within said optical cable clamp, and after said optical cable clamp is inserted and secured within said end sleeve, the optical fiber of said optical cable is inserted within said housing and butt-joined with the embedded optical fiber within said ferrule. As a result of this, before the butt-joined optical fibers are locked in, the optical cable has already been secured within the optical cable clamp and fixed to the connector housing. Therefore, the butt-joined optical fibers cannot be separated due to the effects of unexpected pulling force, thus ensuring the optical fiber of the optical cable reliably abuts the embedded optical fiber.

  • Patent number: 9632257
    Abstract: A plug part for a plug-in connection, in particular of optical conductors, includes a plug housing, in which a plug insert having at least one plug pin for receiving a conductor is arranged. The plug part can be inserted into a correspondingly designed socket part in an insertion direction (A), and includes a locking means for releasably locking the plug part in the socket part. The plug part further has an unlocking means, by means of which the locking of the locking means to the socket part can be released. The plug part includes a protective apparatus for protecting the end face of the plug pin and for moving from a closed position with a covered end face to an open position with an exposed end face by inserting the plug part into the socket part by interacting with the socket part.

  • Patent number: 9557496
    Abstract: A duplex clip assembly for LC fiber optic plug connectors has a duplex housing, a crimp sleeve, and a housing cover. The duplex housing retains a portion of each fiber optic plug connector such as to allow each fiber optic plug connector to rotate relative to the duplex housing. The housing also has a bottom snap located on an underside. The housing cover encloses and retains the duplex housing with a clearance between the housing cover and the rest of the assembly. The housing cover also has a slot located on an underside configured to engage the bottom snap of the duplex housing such that the clearance fit allows an application of pressure on the sides of the housing cover to result in the slot being disengaged from the bottom snap. The clip assembly can also have a boot securely attached to the housing partially enclosing the fiber optic cable.

  • Patent number: 9535231
    Abstract: An optical fiber assembly of the present invention is configured such that an optical fiber fixing section (i) is fixed to an SUS tube and (ii) sandwiches an optical fiber between a first member and a second member at an end part of the SUS tube, so that the optical fiber is fixed while being spaced from the SUS tube. This makes it possible to provide an optical fiber assembly having a structure that prevents an optical fiber from coming into contact with an edge part of a metal tube on the premise that the optical fiber is covered with the metal tube.
