Heat-shrinkable jacket for EMI shielding
First Claim
1. A heat-shrinkable electromagnetic interference (EMI) shielding jacket sheathable over a generally elongate object of a given outer diameter extent, said jacket comprising:
- a tubular outer member of an indefinite length and an expanded inner diameter which is greater than the outer diameter of the object, said outer member being heat-shrinkable to a recovered inner diameter smaller than said expanded inner diameter substantially conforming said jacket to the outer diametric extent of the object;
an electrically-conductive, tubular inner member received coaxially within said outer member and extending coextensive therewith; and
a generally continuous, thermoplastic interlayer interposed between said outer and inner members and extending coextensive therewith, said interlayer bonding said inner member to said outer member along substantially the entire length thereof for consolidating said jacket into an integral structure,wherein said tubular outer member is partially constricted about said inner member to a diameter intermediate said expanded and recovered diameters for exerting a generally radially compressive force on said inner member further consolidating said jacket into said integral structure.

Abstract
A heat-shrinkable electromagnetic interference (EMI) shielding jacket sheathable over a generally elongate object of a given outer diameter extent. The jacket is formed of a tubular outer member of an indefinite length and an expanded inner diameter which is greater than the outer diameter of the object, an electrically-conductive inner member received coaxially within the outer member and extending coextensive therewith, and a generally continuous, thermoplastic interlayer interposed between the outer and inner members and extending coextensive therewith. The interlayer bonds the inner member to the outer member along substantially the entire length thereof for consolidating the jacket into an integral structure. The outer member, in turn, is heat-shrinkable to a recovered, i.e., contracted inner diameter smaller than the expanded inner diameter for substantially conforming the jacket to the outer diametric extent of the object.
