Method and apparatus for simultaneously connecting data/signal communication lines and power lines to a data/RF receiver/transmitter
First Claim
1. A combination power cord and antenna/signal line coupler for data/signal receiver/transmitter apparatus, comprising:
- a power cord having a single conduit including first and second power conductors and a coaxial cable extending therethrough, and a three-prong plug including a pair of power prongs electrically connected to the power conductors, and a coaxial ground prong having a conductive outer sleeve connected to the outer conductor of the coaxial cable, and a coaxial inner conductor connected to the inner conductor of the coaxial cable; and
a wall receptacle unit including a pair of openings for receiving said power prongs and a ground prong-receiving bore having signal coupling means formed at the internal extremity thereof, said signal coupling means including an electrically conductive outer sleeve for engaging the outer conductor of said ground prong and an electrically insulative inner sleeve having an axially extending passageway for receiving the internal conductor of said ground prong, the terminating end of said outer sleeve forming a connector to which a signal-carrying cable can be connected to communicate electrical signals passed through the internal conductor.

Abstract
Television power, antenna and data coupling apparatus including the substitution of a coaxial cable or metal clad fiberoptics cable for the standard grounded wire of a typical power cord, with the ground prong being configured to form the male component of a coaxial jack connector. Similarly, at least one of the ground plug receptacles of a dual or other multiple socket wall connector is modified to form a female coaxial connector for receiving the male component of the jack connector. The outer conductor of the coaxial jack connector and the outer conductor of the female receptacle connector are used to provide the standard ground connection for the plug and receptacle. The inner metal and/or glass fiber conductors form the principal signal paths. Since the female component of the receptacle is of the same internal diameter as the standard ground pin receptacle, the plugging of a standard three-prong plug into the modified receptacle provides power to the plug in the identical manner of the non-video/data receptacle.

5. Apparatus for simultaneously connecting data/signal communication lines and power lines to a data/RF, receiver/transmitter device comprising:
-
plug means including a pair of power prongs and a ground prong, said power prongs being adapted for connection to the power ports of a receiver/transmitter device, said ground prong having first inner and outer coaxial electrical conductors, said outer electrical conductor being adapted for connection to the ground port of the receiver/transmitter device, said inner electrical conductor being adapted for connection to the data/signal port of the receiver/transmitter device; and receptacle means including first and second openings for receiving said pair of power prongs and a third opening for receiving said ground prong, said receptacle means further including first and second electrical contacts associated with said first and second openings and adapted for connection to the first and second conductors of a power line, a third electrical contact associated with said third opening and adapted for connection to a ground conductor of the power line, and a coaxial connector having an internal conductor and an external conductor for connection to a data/signal line, the external conductor of the coaxial connector being connected to said third electrical contact, whereby upon the mating of said plug means with said receptacle means, power is supplied to the receiver/transmitter device and data/RF signals may be communicated between the data/signal line and the receiver/transmitter device via said coaxial connector. - View Dependent Claims (6, 7, 8, 9, 10)
