219CORE INSULATION (E.G., BETWEEN CORE PARTS)


DEFINITION

Classification: 336/219

(under the class definition) Inductor devices comprising a core built up of elements of magnetic material separated from each other by elements of electrically insulating material. Laminated cores with electrical insulation between the magnetic laminations of the core are in this subclass.

(1) Note. For other classes providing for processes of forming laminations, laminating, or to the resulting products, see classes listed under "SEARCH CLASS", of subclass 234 of this class.

SEE OR SEARCH THIS CLASS, SUBCLASS:

60, for core structure having insulating spacers between core parts to provide ventilating passages for the core.

61, for core structure having heat exchanging surfaces

between core parts and insulated therefrom.

100, for inductors wherein the core parts may be separated by resilient insulating material to damp out electro-mechanical vibrations produced by the inductor. 134+, for inductors with an adjustable air gap between relatively movable core parts.

165, for inductors of the high leakage reactance type wherein the core has a shunt path with an air gap.

177, for inductors with a coil formed of an electrically insulated conductor of magnetic material.

178, for inductors with a closed type core having an air gap.

198, for inductors with preformed electrical insulation between coil and core.

211, for inductors with a core comprising concentric or nested magnetic elements with electrical insulation between elements.

212, for inductors with plural part cores (e.g., an assemblage of preformed leg and yoke portions) with electrical insulation between core parts.

213, for inductors with a core formed of a continuous, wound strip of magnetic material with electrical insulation between turns.

216+, for inductors having core joint structure wherein electrical insulation may be disposed between the core parts of the joint.

234, for the structure of laminated cores in general.
