August 16, 2013. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesFiber optic connector with split ferrule assembly Optical fibre termination Optical waveguide connector Connectors for optical fibres Adhesiveless optical fiber connector Connector for fiber optic cables Fiber optic connector System for use in temporary repair of multiple fiber cable Housing for a fiber optic component Connector device comprising a receptacle part surrounding the light waveguide InventorsAssigneeApplicationNo. 139046 filed on 08/16/1993US Classes:385/81, Compressively fixed (chuck, collet, crimp, set screw, etc.)385/62, Compressively fixed (e.g., chuck, collet, crimp, set screws, etc.)385/65, Groove-type holding structure385/66, Tube-type holding structure385/78, Fiber end held in ferrule385/83, Groove-type holding structure385/84, Tube-type holding structure385/136, External retainer/clamp385/137, Fiber holder (i.e., for single fiber or holding multiple single fibers together)385/139Plug/termination deviceExaminersPrimary: Healy, BrianAttorney, Agent or FirmInternational ClassesG02B 006/36G02B 006/38 Foreign Application Priority Data1991-08-16 JPAbstractAn inner, optical fiber core clamping ferrule has an optical fiber clamping portion for receipt in an outer ferrule and defining an axially extending through-passageway, an axial slit extending through the clamping portion divides the passageway into two opposed groove portions receiving a prepared end of an optical fiber extending along the through-passageway. The inner ferrule is force-fitted in the outer ferrule to extend co-axially therewith, with wall portions thereof maintaining the opposed walls of the spaced apart slit in open condition so that opposed walls of the groove portions are pressed into gripping engagement with the optical fiber. The opposed walls of the slit diverge as they extend radially outwardly away from the groove portions. The inner ferrule may be split for the entire length of the through passageway forming two halve hinged together at one end or have open slits formed in an otherwise imperforate tubular wall.Field of SearchFiber end held in ferruleCompressively fixed (e.g., chuck, collet, crimp, set screws, etc.) Groove-type holding structure Tube-type holding structure With additional structure at or immediately surrounding each optical fiber end face Fiber end held in ferrule Optical fiber/optical fiber cable termination structure Fiber end held in ferrule Compressively fixed (chuck, collet, crimp, set screw, etc.) Groove-type holding structure Tube-type holding structure Having at least one layer compressively fixed (e.g., crimp, tightening screws, etc.) Optical fiber to a nonfiber optical device connector Plural fiber/device connections Plug/termination device External retainer/clamp Fiber holder (i.e., for single fiber or holding multiple single fibers together) | |
