Abstract
A waterproof housing which is intended to be buried in the ground, and which serves to protect the splices of buried electrical cables such as are used, for example, in irrigation control systems. The housing is formed of two identical half-sections configured to snap together around the crimped splice of two or more cables. Each half-section is pre-filled with a plastic insulating gel which becomes adhesively attached to the crimping sleeve of the splice and which forms a perimeter seal around the splice. Troughs are provided at one end of each section as a means of entry for wires to be spliced. Thin frangible dams are molded onto the outer ends of the troughs to maintain the gel in the half-sections during filling, and which are crushed by the cables when the two half-sections are pressed together.
