(under the class definition) Inductor devices provided with a casing or housing to enclose the inductor device.
(1) Note. The casing or housing surrounding the inductor device in the patents of this and indented subclasses is disclosed primarily as a mechanical protection for, or to contain an insulating medium around, the inductor.
(2) Note. If the casing or housing is claimed as an electric or magnetic shield the patent is excluded and classified in subclasses 84+.
(3) Note. For classification in this or indented subclasses some detail of the inductor device such as a winding must be claimed. If the recitation in the claim of an inductor device is by name only, the patent is not classified herein but rather in the appropriate subclasses in Class 174.
SEE OR SEARCH THIS CLASS, SUBCLASS:
55+, for inductor devices having casings combined with means to modify the temperature of the inductor. See especially subclass 59 for vented casings. 65+, for inductor devices having casings with external mounting means.
82, for inductor devices wherein a unitary preformed coil or winding forms the casing.
83, for inductor devices wherein the core forms a casing for the windings.
