Abstract: An enclosure for encapsulating and sealing a splice between two or more underground cables is disclosed. A tubular chamber is provided to receive the splice, and the chamber has a radial access hole for pouring plastic compound into the chamber. The cables to be spliced pass through caps which enclose the ends of the chamber. A rotatable sleeve fits over the center of the chamber. The sleeve has an aperture corresponding to the access hole in the tubular chamber, and an outwardly projecting funnel extending from the aperture. The aperture in the sleeve can be aligned with the access hole and liquid plastic compound poured through the funnel into the tubular chamber to surround the splice. When the chamber has been filled with plastic compound, the sleeve can simply be rotated with respect to the chamber and locked to disalign the aperture and the access hole and thereby seal the chamber.

Abstract: A versatile protective closure for a cable splice comprising complementary mating body portions having a generally cylindrical shape terminating in serrated tapered ends, each portion including a pair of longitudinally extending flange portions each having an inner and an outer raised rim portion. The rim portions have alternate tongues and grooves arranged to define separate central and outer enclosed chambers when the two body portions are mated to form a casing about a cable. The top body portion has inner and outer filling apertures at each end in communication with the central and outer enclosed chambers, and a pair of optional annular partitioning members can be received internally in a region between adjacent inner and outer filling apertures to provide fluid isolation between the central and outer chambers. A plurality of axially spaced, circumferentially extending stiffener ribs are grooved to receive optional closure bands.
