DUPLEX OPTICAL FIBER CONNECTOR

摘要

DUPLEX OPTICAL FIBER CONNECTOR A duplex optical fiber connector includes a housing having a cable entrance end and a plug end. At the cable entrance end, an optical fiber cable which includes two individually buffered optical fibers, strength member yarn and a plastic jacket is routed into a flanged end of a bushing having a tapered passageway therethrough. The bushing is supported in a base of the housing. The jacket is removed from the portion of the cable which extends from the cable entrance end to the plug end and the yarn is positioned between two conformable, truncated conically shaped, substantially smooth surfaces which define the passageway of the bushing and a truncated conically shaped wedge which is received in the passageway. The wedge includes a bore through which the optical fibers extend. This locking arrangement in which the yarn makes no retroflexed turns is self-enhancing when tensile forces are applied to the cable. At the plug end are secured two plugs each terminating one of the optical fibers. Each plug is spring-loaded and further, end portions of the plugs which protrude beyond the connector housing are protected by a bumper which also is spring-loaded and which is moved inwardly when the connector is assembled to another. A cover is assembled to the base to complete the housing and to secure the force-transfer facilities and plugs therein.
