  • Cleaning tool for optical connector
    Patent number: 6810552
    Abstract: A cleaning tool for an optical connector includes a cylindrical cleaner and a holding member for holding a proximal portion of the cleaner. The cleaner has a main body with a ferrule insertion hole extending from a ferrule insertion port at its distal end face toward the proximal end of the cleaner. The ferrule insertion hole has an inner diameter substantially the same as an outer diameter of a ferrule. The ferrule insertion hole is surrounded by a rough surface so as to clean an outer surface of the ferrule which is to be inserted.
    Type: Grant
    Filed: March 28, 2002
    Date of Patent: November 2, 2004
    Assignee: NTT Advanced Technology Corporation

  • Cleaning tool for optical fiber connectors
    Patent number: 6466723
    Abstract: A cleaning tool for cleaning optical fiber connectors exposes a cleaning sheet in a window of the case. A winding pulley is operable to wind the cleaning sheet upon rotation at a constant pitch. A rotation mechanism, that is operated by a lever, rotates the winding pulley. The case is constructed of a first front plate and a second front plate which are closed off by a perimeter wall along their outer circumference. The case has an open portion in a part of the perimeter wall, and the lever is disposed in the open portion in an inclined orientation.

    Abstract: The cleaning tool for optical fiber connectors exposes the cleaning sheet in the window for cleaning of the case. The winding pulley winds the cleaning sheet with rotating in a constant pitch. A rotation mechanism operated by lever rotates the winding pulley. In the case, a first front plate and a second front plate is closed off by a perimeter walls along their outline. The case has the opened portion opening a part of the perimeter wall, and the lever is disposed in the opened portion to be able to incline.
