Abstract
Flexible electrical shielding conduit and method for making same wherein the conduit comprises multiple layers including a flexible conduit tubing outer layer, an electrical shielding layer disposed within the tubing and in contact with the conduit layer, and a woven retaining layer inside the shielding layer, said woven retaining layer expanding radially outwardly when compressed axially continuously forcing the shielding layer into contact with the conduit tubing to provide an unobstructed passageway therethrough. An alternative embodiment and the method for making same wherein the electrical shielding layer and the retaining layer are combined to form an integral inner layer having the properties as described above.
Claims16
Flexible electrical shielding conduit comprising:
- flexible conduit tubing having an internal cross-section;
- a generally tubular flexible electrical shielding means having a predetermined thickness disposed within the conduit tubing;
- and
- axially compressible radially expansible retaining means for forcing the shielding means into contact with the tubing disposed inside the shielding means and in contact therewith, the external cross-section of retaining means being preset in axial compression at least as great as the internal cross-section of the conduit tubing less twice the thickness of the electrical shielding means.
Flexible electrical shielding conduit comprising:
- flexible conduit tubing having an internal cross-section,
- a generally tubular flexible electrical shielding means having a predetermined thickness disposed within the tubing;
- and
- axially compressible radially expansible retaining means for forcing the shielding means into contact with the tubing disposed within the shielding means and in contact therewith, the retaining means being operatively interconnected with the conduit tubing and maintaining the retaining means in axial compression at least as great as the internal cross-section of the conduit tubing less twice the thickness of the electrical shielding means.
