Abstract

A hydrostatic sealing sleeve hydrostatically seals a spliced wire connect in high pressure underwater conditions. The sealing sleeve is fashioned from an elastomeric compound, such as neoprene, and is fitted over one end of an insulated wire that is to be spliced onto a butt wire splice. The other insulated wire is spliced together with the first wire and the sealing sleeve is then slid over the butt wire splice where it rests in a centrally located cavity inside the sleeve. The outer ends of the sealing sleeve include sealing baffles which compress onto the outer peripheral surfaces of the insulated wires, creating a high pressure water tight seal.

Claims

1. A method of installing a sealing sleeve over a butt wire spliced connection between first and second insulated wires, said hydrostatic sealing sleeve comprising a length of heat-stable elastomeric tubing having first and second ends, an internal cavity centrally located between said first and second ends, and at least one internal hydrostatic sealing baffle positioned adjacent each of said first and second ends, said method comprising the steps of:

lubricating said first and second ends of said sealing sleeve with a silicone gel compound;

sliding said first end of said sealing sleeve over the end of said first insulated wire;

stripping the insulation from the ends of said first and second insulated wires;

inserting said stripped ends of said first and second wires into a butt wire splice and crimping said butt wire splice to form a spliced connection between said first and second wires; and

sliding said sealing sleeve over said crimped butt wire spliced connection so that said spliced connection is positioned in said internal cavity, said hydrostatic sealing baffles compressing against an outer periphery of said first and second wires to form a high-pressure water-tight seal therewith.
