Splice closure and grip block

摘要

An optical fiber cable closure assembly includes a base member and a mating cover which, when assembled form a hollow splice closure with openings at each end. Mounted to the base member at at least one end thereof is a grip block assembly which grips the optical cable entering the adjacent open end, and which automatically adjusts to differing sizes of cables. The grip block assembly has an upper member and a lower member and includes first and second pivotally mounted arms on the lower member which are actuated by actuating pins on the upper member and which, as the upper member is tightened down on the lower member, pivot until they bear against and grip the cable. Included within the closure assembly are one or more optical fiber splitters which are used to separate and segregate individual fibers or groups of fibers to be spliced. One or more fiber splice trays are mounted on the base member and function to hold a plurality of splices of any of a large number of types in position after the fibers are spliced, and to store excess fiber without allowing the fibers to be bent to their critical bending radius.
