DEFINITION

Classification: 174/102

(under subclass 68.1) Structures in which one or more conductors are enclosed in, but insulated from, an electrically conductive armor or sheath.

(1) Note. An armor or sheath as used herein includes any surrounding conduit, tube, wrapping, winding, layer, coating, or other enclosing structure. Such structures may be inherently conductive, as when made of metal, or may be rendered conductive by incorporation of conductive ingredients or particles.

(2) Note. While the conductivity of the armor or sheath is essential to cause classification in this subclass and indented subclasses, it is not necessary that the armor or sheath be intended to carry an electric current. Thus, this subclass and indented subclasses include, for example, armors or sheaths (a) provided solely for mechanical protection when claimed as made of conductive material, and (b) having an electrical function such as corona prevention, grounding, shielding, etc., or constituting the outer conductor of a coaxial or concentric type cable.

(3) Note. For structures employing anti-inductive means in addition to the conductor armor or sheath, see this class, subclass 32 and indented subclasses, especially subclass 36.

(4) Note. For conductively armored or sheathed conductors or cables employing a fluid or vacuum, see this class, subclass 8 and indented subclasses, especially subclass 24 and indented subclasses. See particularly subclasses 28 and 29 for coaxial or concentric type cables.

(5) Note. For conductors or cables armored or sheathed solely by insulation, see this class, subclass 110 and indented subclasses.

(6) Note. For mere hollow conductors not forming an enclosure for another conductor, see this class, subclass 126.1 and indented subclasses, especially subclasses 130 and 131. SEE OR SEARCH CLASS
