PLUG CONNECTION CONTACT WITH HIGH SECURITY AGAINST BURNING OFF

An electric connector for high circuit loads having an inner contact portion and an outer contact portion for the purposes of minimizing the arc encountered in switching high circuit loads. In an assembled position, a mating contact is electrically engaged by both the inner and the outer contact portions of the connector. When being removed from the connector, the mating contact disengages from the inner contact portion of the connector first, while maintaining electrical contact with the outer portion of the connector. As the mating contact element is further withdrawn, it disengages from the outer contact portion of the connector, and any arcing, occurring as a result of the discontinuity of low resistance contact, will occur between the mating contact element and the outer portion of the connector plug. The outer portion of the connector plug is composed of a material offering a high resistance to burning-off and is provided with an inwardly inclined surface at the entry portion of the connector to cause arcing to take place on such incline. The inner portion makes low resistance connection with the mating connector, and, by the action of the outer connector portion, is protected against the effects of arcing.
