Fiber optic enclosures employing clamping assemblies for strain relief of cables, and related assemblies and methods

摘要

Fiber optic enclosures employing clamping assemblies for strain relief cables and related assemblies and methods are disclosed. The fiber optic enclosures may be part of a fiber optic terminal in a fiber optic network. The fiber optic enclosures may include openings in the walls of the fiber optic enclosure. A cable fitting assembly may be attached to a portion of the wall around an opening to form a passageway for fiber optic cables to enter the fiber optic enclosure. An elongated member may be used to guide the fiber optic cables through the passageway. The elongated member may have a first end and second end. The elongated member may include a clamping assembly at the first end to provide strain relief to the fiber optic cables by clamping strength members of the fiber optic cables.

主权项

1. An elongated member for sealing off an opening disposed through an enclosure wall having a plurality of fiber optic cables disposed therethrough, comprising:
a first end and a second end disposed opposite the first end along a longitudinal axis, the second end configured to guide a plurality of fiber optic cables into an opening of an enclosure; a strain relief portion disposed at the first end, the strain relief portion includes a plurality of recesses forming a plurality of openings configured to each receive one of the plurality of fiber optic cables, each of the plurality of recesses separated by one of a plurality of external surfaces and disposed parallel to the longitudinal axis; and a clamping assembly disposed at the first end, the clamping assembly configured to clamp strength members of the plurality of fiber optic cables, wherein the clamping assembly comprises:
a threaded bushing attached to the first end;a fastener in communication with the threaded bushing;a strength member gap configured to receive a portion of the strength members; anda bushing protrusion, the bushing protrusion includes a protrusion surface configured for the portion of the strength members to be wrapped around.
