(under subclass 70) Structures claiming the joint between the ends of conduits, cables or conductors.
(1) Note. Compare this class, subclass 75, for cable, conduit, or conductor end structures with joints.
(2) Note. See this class, subclasses 21 and 22, for joints utilizing fluids.
(3) Note. See this class subclasses 71 and 72, for joints for associating conduits, cables or conductors in branching relation.
(4) Note. See Class 439, Electrical Connectors, for electrical connectors, generally, and see especially Lines With Other Classes and With This Class in that class (Class 439) definition for the line between this Class 174) and that class with regard to electrical joints.
(5) Note. See Class 285, Pipe Joints or Couplings, subclasses 47+ for joints or couplings heat and/or electrically insulated, having no added features limiting the same to electrical use.
(6) Note. See Class 403, Joints and Connections, appropriate subclasses, for conductor joints where no features restricting the same to the electrical arts, such as the use of insulation to insulate the conductively coupled wires or the structure of the conductor to improve the same for conducting electricity, are claimed. Features which are designed to make better metal to metal contact at the joint and thus improve the strength of the joint and also the electrical conductive properties have been placed Class 403. (7) Note. See Class 156, Adhesive Bonding and Miscellaneous Chemical Manufacture, subclass 49 for methods of splicing indefinite length electric conductors.
