Optical fiber splice closure assembly
First Claim
1. An enclosure for supporting at least one fiber optic cable, which comprises:
- (a) housing having first and second end portions;
(b) at least one end plate located at each said end portion, each said end plate defining at least one aperture for supporting at least one fiber optic cable extending therethrough;
(c) a strain relief device for gripping said at least one fiber optic cable adjacent at least one of said end plates, said gripping device having a plurality of spaced apart arcuately shaped fingers for substantially encircling the cable and having at least one extension adapted for attachment to said at least one end plate to fix the axial position of the cable gripped thereby; and
(d) a clamp member for encircling said gripping device and for urging said fingers into biting engagement with said at least one cable.

Abstract
An improved closure assembly for retaining fiber optic cables is disclosed wherein the closure assembly includes end plates having apertures for supporting the cables at the location of entry into the closure assembly. A unique gripping device is provided for retaining each cable with respect to the end plates, whereby sufficient force is applied to the cable to provide water-tight sealing at the junction of the cable and the end plate, yet with sufficient distribution of the force to avoid straining or distorting the cable. A unique optical fiber splice tray is disclosed having pivotal connectors at either end to permit attaching the trays in stacked relation, yet providing pivotal movement of each tray relative to the next adjacent tray, from either end. The trays include unique “V”-shaped integral fingers for retaining the individual optical fibers while permitting ready removal and reinsertion of the fibers for servicing of the closure assembly or the fibers.

10. A splice tray for supporting optical fibers, which comprises:
-
a) a tray for supporting the optical fibers in an axial direction; and
b) a tray-to-tray connecting device located at each end of said tray, each said connecting device being comprised of at least one elongated generally cylindrical member positioned adjacent at least one clamp member adapted to engagingly receive in clamped relation, one of such cylindrical members attached to an adjacent similar tray in a manner to permit relative pivotal movement therebetween, such that at least two of such trays may be stacked in connected relation whereby said trays may be pivotally rotated with respect to each other from either end. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A device for supporting a fiber optic cable with respect to an enclosure, the enclosure having at least two end portions, and an end plate at each said end portion defining at least one aperture for reception of the fiber optic cable, which comprises:
-
(a) gripping device structured to substantially encircle the cable at a location adjacent at least one of said end plates, said gripping device having at least two gripping members adapted to move toward and away from an outer surface portion of the cable between positions whereby the cable is gripped and released, respectively;
(b) a split washer-like member extending generally radially from said gripping device at at least one end portion thereof, said member adapted to be fixedly attached to the end plate; and
(c) an encircling member adapted to encircle said gripping device and to selectively apply inward force to said gripping device to cause said gripping device to grip the cable. - View Dependent Claims (19, 20, 21)
