Abstract
Armored cable sheath is coded for easy visual identification by applying patterns, e.g., colored patterns, along the length of the cable. The sheath may be formed of a helically interlocked continuous strip of metal, or of smooth or corrugated continuous metal tubing. The patterns are applied on the outer surface of the sheath and are repeated along the length of the sheath.
Claims51
An armored cable sheath comprising
- a conductive tubular structure having an internal passage, an outer surface, a first end, and a second end, the internal passage being sized and configured to enclose one or more conductors, said tubular structure being made of a material having a first visual appearance, and
- a pattern of visible indicia, of different visual appearance from said first visual appearance, applied on said outer surface, said pattern being repeated along the length of said sheath.
Apparatus comprising:
- a tubular conductive sheath having first and second ends and inner and outer surfaces, the inner surface of the sheath defining an internal passage sized and configured to enclose one or more conductors;
- visible indicia displayed on the outer surface of the sheath, the visible indicia spanning between the first and second ends of the sheath and providing the outer surface of the sheath with a visual appearance different from a visual appearance of the outer surface of the sheath without the visible indicia.
Apparatus comprising:
- a tubular conductive sheath having first and second ends and inner and outer surfaces, the inner surface of the sheath defining an internal passage sized and configured to enclose one or more conductors;
- a substantially conductive coating disposed on the outer surface of the sheath, the coating having a visual appearance different from a visual appearance of the outer surface of the sheath.
Apparatus comprising:
- a tubular conductive sheath having first and second ends and inner and outer surfaces, the inner surface of the sheath defining an internal passage sized and configured to enclose one or more conductors;
- and
- visible indicia that permit electrical conductivity, are displayed along at least a portion of the sheath between the first and second ends of the sheath, and impart to the outer surface of the sheath a visual appearance different from a visual appearance of the outer surface of the sheath without the visible indicia.
A method comprising:
- providing a tubular conductive sheath having first and second ends and inner and outer surfaces, the inner surface of the sheath defining an internal passage sized and configured to enclose one or more conductors, the sheath bearing visible indicia that permit electrical conductivity, are displayed along at least a portion of the outer surface of the sheath between the first and second ends of the sheath, and impart to the outer surface of the sheath a visual appearance different from a visual appearance of the outer surface of the sheath without the visible indicia, and
- attaching a connector to the sheath in such a manner that the connector makes electrical contact with the outer surface of the sheath.
