DEFINITION

Classification: 336/216

(under the class definition) Inductor device comprising the particular core structure at the point of juncture of magnetic elements or parts of the core. The elements or parts are usually the leg and yoke members of the core.

SEE OR SEARCH THIS CLASS, SUBCLASS:

132+, for inductors having plural joined core parts with means to permit relative movement therebetween for adjusting the inductance of the device.

165, and 178, for inductor cores having a high reluctance gap

in the magnetic circuit, which gap may be bridged by nonmagnetic material to effect a joint between the two opposed parts of the core.

173, for inductors having a core with a joint comprising hinged parts to permit clamping of the core about a conductor or coil means.

210, for inductor core joint structure with means, in addition to the core elements themselves, to clamp, wedge or otherwise hold the core elements together. 212, for inductor cores comprising an assemblage of preformed core parts (such as leg sections and yoke sections) which include significant joint structure between the parts.

213, for inductor cores having joints between core elements of coiled or wound magnetic material.

214+, for inductor cores with core elements providing multiple magnetic paths and having significant joint structure between the elements.

29, Metal Working,

602.1+, for processes of manufacture assembly of inductor devices, especially indented subclass 606 for assembly of coil and core, and subclasses 607+ for core assembly. Apparatus for assembling an electrical inductor device may be found in subclasses 729+, and a device for securing parts together by a hollow rivet, when not elsewhere classifiable, may be found in subclass 243.52.

228, Metal Fusion Bonding,

101+, for a process of metallurgically bonding an electrical connection and especially subclasses 179+ for a process of a metallurgically bonding plural joints of electrical devices. See the search notes in Class 228 for other classes and subclasses providing for making electrical joint structure.

310, Electrical Generator or Motor Structure,

10+, for dynamoelectric machine structure, indented subclasses 40+ for rotary machines particularly subclasses 179+ for winding and core structure of rotary machines, subclasses 216+ indented under subclass 179, providing for core features including joint structure, subclasses 254+ providing for stator structure in general, while subclasses 261+ provides for rotor structure in general, which structures may include joint structure.

403, Joint and Connections, appropriate subclasses for joints of general utility.
