ABSTRACT:
A universal AC/DC electrical connector for selectively coupling either a mating direct electrical current (DC) electrical connector or a mating alternating electrical current (AC) electrical connector to selectively receive both direct electrical current (DC) and alternating electrical current (AC) therein. The AC/DC electrical connector has a pair of direct current contacts, a pair of alternating current contacts, and a ground contact. When DC electrical connector is coupled to the AC/DC electrical connector, the direct current contacts and the ground contact electrically engage corresponding electrical contacts of the DC electrical connector, while the alternating current contacts of the AC/DC electrical connector remains uncoupled, i.e., alternating current connects of the AC/DC electrical connector does not electrically engage the contacts of the DC electrical connector. When AC electrical connector is coupled to the AC/DC electrical connector, the alternating current contacts and the ground contacts of the AC/DC electrical connector engage corresponding electrical contacts of the AC electrical connector. The AC/DC electrical connector can also be provided with a sensor in the form of a pilot contact or reed switches for determining whether direct electrical current or alternating electrical current is being supplied thereto.
