DEFINITION

Classification: 338/274

(under subclass 273) Subject matter wherein distinct structure such as a disc, seal, or cap is provided between the casing and the terminal or lead conductor to seal any space existing therebetween.

(1) Note. For classification in this subclass distinct sealing structure is necessary, as opposed to a mere tight fit or adhesion between the casing and the terminal or lead, which subject matter is classified in the generic subclass 273.

SEE OR SEARCH THIS CLASS, SUBCLASS:

233, for a resistor whose casing or housing is elongated in shape and has a plug disc or cap at the end for ready opening of the casing and/or separation from the resistance element.

237, for resistors whose elements are hermetically sealed in spaced relation from their casings or housings.

269, and 275, for resistors with molded or fused casings and housings which may be directly sealed to the terminals. SEE OR SEARCH CLASS
