DEFINITION

Classification: 439/181

INCLUDING ARC SUPPRESSING OR EXTINGUISHING MEANS:

(under the class definition) Electrical connector combined with or having means to inhibit electrical discharge or the effects of electrical discharge in the vicinity of the electrical joint forming means resulting from the making or breaking of the electrical connection.

(1) Note. Provision to cause arcing at one location, e.g.., at a spark gap, thereby inhibiting arcing at another location is included herein.

(2) Note. Provision to prevent arcing from a contact to an adjacent contact on a connector, e.g.., from one to another of the prongs of an electron tube, is considered to be an insulator rather than an arc suppressing or extinguishing means.

SEE OR SEARCH THIS CLASS, SUBCLASS:

38+, for a connector using magnetic means to suppress or extinguish an arc.

88, for an electrical connector including an elastomeric or nonmetallic conductive portion having inductive shielding or arc suppressing means.

135+, for a connector having cover means automatically moving upon separation of the connector from a mating part.

180, for a connector having means to move its contact away from the contact of a cooperating connector by a snap or quick-break action, which might incidentally thereby suppress the arc. SEE OR SEARCH CLASS

218, High-Voltage Switches With Arc Preventing and Extinguishing Devices,

1+, for an arc suppressing or extinguishing means for a circuit maker or breaker.
