(under subclass 50.5) Subject matter in which the envelope has combined therewith an electrical connector for connecting a lead-in conductor of the envelope to an external conductor, or where the envelope has a portion thereof formed so as to be at least a part of an electrical connector.
(1) Note. This and the indented subclass includes hermetically sealed envelopes such as are used for electric lamps, electric space discharge devices, and similar devices which are provided with a screw type or plug type base as well as envelopes where the lead-in conductors are either shaped so as to form electrical connectors or are of sufficient rigidity to form contacts (usually plug type contacts) subject to the limitations of (2) Note. The
indented subclass includes devices where a portion of the enclosing wall of the envelope is shaped so as to form an electrical connector.
(2) Note. This subclass provides for the structure of the envelope with connector structure where significant structure of envelope is recited in addition to that necessary to support or mount the electrical connector. See section 17.5 of the class definition of this class (174). See Class 439, Electrical Connectors, for electrical connector structure, and see especially subclasses 611+ for the combination of a vitreous envelope and an electrical connector in which no significant structure of the envelope is recited other than that necessary to support or mount the electrical connector.
