DEFINITION

Classification: 313/331

(under subclass 326) Electrodes and shields which have combined therewith a lead-wire or an electrical connector.

(1) Note. An electrical connector is defined for the purpose of classification in these subclasses as any device or means which is provided for the purpose of attaching a lead wire or conductor to the electrode or shield. The connector may be a part of the electrode or shield structure

or may be merely attached mechanically to the electrode or shield.

(2) Note. Joints and connections between an electrode or shield and a lead wire or connector are not included in this or the indented subclasses unless the structure claimed includes some significant structure of the electrode or shield beyond that which is provided for making the joint or connection. Where the structure of the electrode or shield is not involved excepting such structure as is necessary for the joint, even though the joint is claimed as being for electrically connecting the parts, see the classes referred to in the class definition.

SEE OR SEARCH THIS CLASS, SUBCLASS:

238+, for devices under the class definition which have supporting and/or spacing structure for the electrode or shield. In some of the devices in subclasses 238+ the electrode support is made of electrically conductive material and is used as a lead-in conductor to conduct electricity to the electrode.

SEE OR SEARCH CLASS 174, Electricity: Conductors and Insulators,

144, for arcing rings and electrodes which include as a part thereof electrical connector structure, per se, which are specifically designed for use with the insulators of Class 174.

252, Compositions,

500+, for electrically conductive compositions even if they are coating or plastic compositions such as electrically conductive cements specialized for use in joining an electrode to its lead wire or connector.

420, Alloys or Metallic Compositions,

591, for alloys designed for use in soldering, brazing or welding an electrode to its lead wire or connector.
