Abstract
A sleeve for installation on an electrical conductor for shielding the conductor with respect to the environment in which the conductor resides against electromagnetic interference (EMI). The sleeve is formed of a tubular member made of heat recoverable material and having, in the non-recovered condition, a large central opening through which the wire to be shielded can be passed. The interior of the tubular member is lined with a plurality of conductive leaves or pellicles. One circumferential margin of the pellicles is adhered to the internal surface of the tubular member and the remainder of each pellicle is unattached and remains in overlapping relationship to an adjacent pellicle. When the sleeve is positioned over a conductor to be shielded and energy is applied to the tubular member to effect its recovery, the unattached portions of the pellicles move with respect to one another as the tubular member shrinks to uniformly circumscribe the conductor with an electrically conductive shield. A fusible coating on each of the pellicles that fuses during the shrinking process and then solidifies so as to enhance the structural and electrical continuity of the shield formed by the de…
