ABSTRACT:
An arc quenching electrical connector has a male pin terminal which inserts longitudinally into a receptacle or terminal having a gassing wall engaged concentrically about the receptacle. During “hot unplugging” of the electrical connector, an arc is carried between a tip of the male pin and a contact surface of a leading end of the receptacle. The gassing wall extends over and is directly engaged to a portion of the contact surface. Because the gassing wall is also preferably an electrical insulator, the arc communicates electrically with the exposed contact surface and is biased directly against the gassing wall. The gassing wall, when heated by the adjacent arc, quenches or reduces the energy of the arc by releasing gas which eliminates arc erosion of the terminals.
