ABSTRACT:
A system or method of providing a plurality of power take-offs or power interfaces for low amperage electrical portable work and entertainment devices, including 6 or 12 volt direct current devices directed in particular to the power take-off in automotive vehicles, including but not limited to automobiles, trucks, boats and airplanes, providing power to portable work and entertainment devices such as portable televisions, cellular telephones, computers and other such devices. The improved system or method provides a plurality of receptacles, an electrical connector of a size which is more convenient than the connector accommodated by the vehicle cigarette lighter receptacle, and which is of such structural integrity as to resist deterioration or breaking of wiring. The improvement is particularly directed to the elimination, replacement or substitution of the presently existing standard cigarette lighter receptacle and thus the elimination of the size-linked encumbrance of existing cigarette lighter electrical connections. The facility by which the desired increase in the number and location versatility of receptacles per vehicle can be provided is by allowing the size of the plug and receptacle interface to be reduced though the employment of phono-type plug and jack (RCA plug and jack) electrical connectors in replacement of the present cigarette lighter or pseudo cigarette lighter receptacles and connectors.
