DEFINITION

Classification: 264/272.11

Electrical component encapsulating:

(under subclass 271.1) Processes in which the surrounded or embedded body, or at least a part thereof, is intended for use as component of an electrical circuit.

(1) Note. To be included here the component must be one which controls the electricity, for example, a coil, condenser, or rectifier, and not merely a conductor insulator or outlet, etc. Processing of covering conductors, etc., are classified according to the manipulative step employed.

SEE OR SEARCH THIS CLASS, SUBCLASS:

104, for processes of producing electrical article by shaping conductive materials.

171.1+, for extrusion of plastic material around strandlike or filamentlike preforms which may be electrical conductors.

614+, for other processes of producing electrical articles which include a step of firing shaped articles or preforms.
