Abstract
Abstract A unitary-data-terminal-service outlet is mounted in a wall for providing a data terminal with both electrical power and a link with a central processing computer. An electrical receptacle is housed in a standard outlet box which is mountable to a wall stud. A face plate mounts to the receptacle and extends flush against the wall beyond the box. A hole is provided in the extended portion of the coverplate and a corresponding hole is provided in the adjacent wall board to mount a coaxial-feedthrough-coupler. A coax cable carrying signals to and from the computer is connected from the inner wall to the coupler and a coax cable to the data terminal connects to the outside end of the coupler. In an office building in which it is anticipated to utilize many data terminals, one such data-terminal-service outlet is provided in the wall at each site at which a data terminal is expected to be employed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
122 words
A data-terminal-service outlet for providing a unitary service at which a digital-data-terminal may be connected to a computer and a source of electrical power, comprising: an electrical-power outlet box with an open face; an electrical-power-plug receptacle mounted in said outlet box; a cover plate being mounted over said open face of said outlet box and having an aperture exposing said receptacle, said cover plate lying substantially all in one plane and having an extended portion projecting beyond and away from said box; and a digital data coupling means in said extended portion of said cover plate for coupling digital signals via two cables, respectively, from one side to the other side of said plate, respectively, between said data terminal and said computer.
Claim 2
Dependent Claim
122 words
A data-terminal-service outlet for providing a unitary service at which a digital-data-terminal may be connected to a computer and a source of electrical power, comprising: an electrical-power outlet box with an open face; an electrical-power-plug receptacle mounted in said outlet box; a cover plate being mounted over said open face of said outlet box and having an aperture exposing said receptacle, said cover plate lying substantially all in one plane and having an extended portion projecting beyond and away from said box; and a digital data coupling means in said extended portion of said cover plate for coupling digital signals via two cables, respectively, from one side to the other side of said plate, respectively, between said data terminal and said computer.
Claim 3
Dependent Claim
29 words
The data-terminal outlet of claim 1 wherein said coupling means is comprised of a coaxial-cable feedthrough coupler mounted in a hole provided therefore in said extended cover plate portion.
Claim 4
Dependent Claim
21 words
The digital-data-terminal outlet of claim 2 additionally comprising an insulating means for electrically insulating said feedthrough coupler from said outlet box.
Claim 5
Dependent Claim
25 words
The digital-data-terminal outlet of claim 3 wherein said cover plate is of an insulative plastic and said insulating means consists of said insulative cover plate.
Claim 6
Dependent Claim
54 words
The digital-data-terminal outlet of claim 2 wherein the inside of said cover plate is directed toward said outlet box, and additionally comprising a coax-cable and two coaxial-connectors mounted, respectively, to the two ends of said cable, one of said connectors being mated with said feedthrough coax coupler at said inside of said cover plate.
Claim 7
Dependent Claim
62 words
The digital-data-terminal outlet of claim 4 wherein said coax cable has a length of about 5 to 10 feet that corresponds to the distance between the point in a wall in which said outlet box is intended to be mounted and the space at the top of the wall that may carry a connecting length of coax-cable and a digital-data distribution box.
Claim 8
Dependent Claim
25 words
The digital-data-terminal outlet of claim 4 additionally comprising an electric power cable having one end entering said power-outlet box for connection to said power receptacle.
