Abstract: A three contact barrel power connector assembly is provided. The power connector assembly includes both a connector plug and a connector jack. The connector plug includes an inner body and an outer body transmitting electrical current. The connector plug further includes a center body that transmits a data signal or a low power current. The connector jack includes a housing ground, a housing body, outer contacts that couple with the outer body, inner contacts that couple with the inner body, and a center contact that couples with the center body. The power connector assembly further includes insulators operable to prevent unwanted electrical contact between the connector plug and the connector jack. The connector plug is operable to couple with the connector jack independent of the orientation of the connector plug with respect to the connector jack, provide high levels of power, and effectively transmit data signals in addition to power.
