Abstract
Abstract The present invention relates to a device and method for environmentally sealing a wire splice for use in nuclear power stations and the like. More particularly the device includes three components, an end cap, a sleeve and a separator. The end cap is cross-linked and heat shrinkable. The sleeve and separator fuses under the temperature required for shrinking the end cap. Upon fusing, the sleeve and separator mixes into an impermeable unitary mass in which are embedded the wires.

Claim 1
Independent Claim
162 words
A method of environmentally sealing a wire splice, comprising the steps of: a. removing insulation from the ends of the two wires to be spliced together; b. sliding a heat-shrinkable sleeve onto one of said two wires; c. splicing the two wires together; d. sliding the heat-shrinkable sleeve to and shrinking it down over the splice area; e. bending the joined wires into a U-shape and sliding a sleeve of fusible material over the bent wires and past the shrunk sleeve; f. sliding a heat-shrinkable end cap onto the bent wires with the fusible sleeve positioned in the open end of the end cap; g. inserting a block of fusible material into the sleeve between the wires; and h. heating the end cap adjacent its open end so that it shrinks down and so that at least a portion of the sleeve and block fuse into a unitary mass with the wires embedded therein and with the end cap being bonded thereto.
