(under the class definition) Subject matter including a detachable electrical connector, and a resistor or element thereof being disposed within the connector and in circuit with the terminal or terminals of the connector.
(1) Note. Usually the resistor or element thereof is disposed within an insulating housing or casing of the connector. The resistor or element for classification here must be disposed within some connector structure. Where the resistor is merely mounted externally on the connector or electrically connected thereto, classification is not here. Subclasses 315+ provides for resistors with mounting or supporting means. As between Class 439, Electrical Connectors, and this subclass (220) the claimed recitation of a resistor enclosed in a detachable electrical connector is sufficient for classification in this subclass (220). However, for classification here the complete resistor (element and terminals) must either be claimed, or it must be evident from the context that such a complete resistor be intended in the claim, in addition to the detachable electrical connector. In short this subclass provides for the combination of a distinct detachable electrical connector and a distinct resistance therein. A mere resistance element and its terminals is classified in subclasses 322+ below. The combination of a resistance element nominally recited and a single detachable connector as a terminal of this element is classified in Class 439, Electrical Connectors; or Class 174,
Electricity: Conductors and Insulators, if the element be a conduit or cable and no detachable connector is present, but rather a more permanent connection such as a joint. See also (1) Note under subclass 226 and (2) Note under subclass 238.
(2) Note. The term electrical connector as here used denotes a device which makes an electrical connection between two electrical circuits external thereto, as opposed to a mere plug-in resistor unit as classified in subclass 221 below which merely makes an electrical connection with the resistance element which is a part of the unit.
