Abstract

The present invention provides a connector for terminating and connecting a portion of a cable. The connector is used with a cable having a core comprising synthetic filaments, a polymeric sheath covering the core, an inner sheath comprising braided metallic filaments covering the polymeric sheath, and a polymeric outer jacket covering the inner sheath. Portions of the jacket and the inner sheath are stripped proximate the portion of a cable to be terminated to provide an exposed polymeric sheath and core portion of a first predetermined length and an exposed inner sheath portion of a second predetermined length. A generally tubular outer sleeve, having an axial length at least slightly greater than the length of exposed braided metallic filaments, is positioned so that either sleeve end extends beyond the exposed portion of the braided metallic sheath. An expansion member is disposed between the core and the exposed portion of the braided metallic sheath for expanding at least a portion of the braided metallic sheath radially outwardly to engage the outer sleeve. A sealant is preferably disposed within the sleeve for sealing the portion of the cable so terminated.

Dependent claims

A method for terminating at least a conductive portion of a cable, said cable having a core comprising synthetic filaments, a polymeric sheath covering said core, an inner sheath comprising braided metallic filaments covering said polymeric sheath, and a polymeric outer jacket covering said inner sheath, comprising:

threading said cable into and through a tubular sleeve such that a portion of said cable proximate the portion of said cable to be terminated is exposed,
stripping a segment of said outer jacket from said portion of said cable to be terminated to expose part of said inner sheath,
stripping a segment of said exposed part of the inner sheath to expose a segment of said polymeric sheath and core having a first predetermined length, and to leave an exposed segment of said inner sheath having a second predetermined length,
radially expanding a portion of said exposed segment of the inner sheath by inserting expansion means between said core and said portion of the exposed inner sheath, and
covering said exposed inner sheath segment and said terminal core segment with said sleeve, said sleeve having an axial length which is greater than the second predetermined length and being positioned such that a portion of said sleeve extends beyond said exposed inner sheath and around a portion of said jacket.
