US 5,862,290 A · Optical fiber cable splice closure

Abstract

An optical fiber cable splice closure assembly includes a base member and a mating cover which, when assembled, form a hollow splice closure with openings at each end. One or more cable gripping members are located within the closure adjacent the open ends for gripping cables passing through the open ends, and a cable strength member is located adjacent to, and aligned with, the cable gripping member. One or more elongated pedestals extend from the floor of the base member, each having latching means on the distal end thereof. A splice tray adapter plate is latched to the distal end of the pedestal or pedestals, thereby creating a slack fiber storage space below the plate. The adapter plate can pivotally hold two or more standard splice trays on one side thereof, or a discrete or mass splice tray on the reverse side thereof. A race track grommet member having insert receiving members on each end thereof form a sealing means for the closure when the base member and the cover member are clamped together.

Dependent claims

An optical fiber cable splice closure for containing optical fiber splices comprising:

a housing having a cover portion and a base portion having a floor portion and defining an enclosure having a longitudinal axis and having first and second open ends for cable ingress and egress;
gripping means adjacent to at least said first end for gripping a cable passing through a first open end;
a first elongated upstanding pedestal member mounted on said floor portion and extending upwardly therefrom to a distal end;
means for mounting one or more splice holders on said distal end of said first pedestal member and for defining a slack fiber storage space below said means and between said means and said floor;
and
means for sealing said base portion and said cover portion and said first and second open ends against intrusion of moisture into the interior of said closure.
