Abstract
A braided EMI protective sleeve and method of construction thereof is provided. The sleeve has a braided, tubular wall extending lengthwise along a central longitudinal axis between open opposite ends. The wall includes a plurality of filament bundles, with each filament bundle including a plurality of filaments twisted with one another to form a plurality of loops, wherein a plurality of the loops of each filament bundle are interlinked with a plurality of the loops of an adjacent filament bundle. At least some of the filament bundles include a conductive wire filament to provide the sleeve with an EMI protective shielding capacity.
Claims4
A braided EMI protective sleeve, comprising:
- a braided, tubular wall extending lengthwise along a central longitudinal axis between open opposite ends, said wall having a plurality of filament bundles, with each filament bundle including a plurality of filaments twisted with one another to form a plurality of loops;
- a plurality of said loops of each filament bundle being interlinked with a plurality of said loops of an adjacent filament bundle;
- and
- a majority of said filaments being provided as conductive wire filaments to provide the sleeve with an EMI protective capability,
- wherein at least some of said filament bundles are formed entirely of nonconductive filaments twisted with one another and wherein at least some of said filament bundles include a nonconductive filament twisted with a conductive wire filament.
A method of constructing an EMI protective sleeve, comprising:
- braiding a tubular wall extending lengthwise along a central longitudinal axis between open opposite ends at least in part with a plurality of filament bundles, wherein each filament bundle includes a plurality of filaments twisted with one another forming loops along the length of each filament bundle;
- interlinking a plurality of the loops along the length of each filament bundle with circumferentially aligned loops of an adjacent filament bundle;
- providing a majority of the filaments as conductive wire filaments to provide the sleeve with an EMI protective capability;
- further including providing at least some of the filament bundles including a nonconductive filament twisted with a conductive wire filament;
- and
- further including providing at least some of said filament bundles being formed entirely of conductive filaments twisted with one another.
