Abstract

A wall plate for premise wiring. The wall plate is preterminated with a quick-connect coupling to enable fast connection and disconnection with a complementary quick-connect coupling on a wire configured to carry an electrical signal, such as digital or analog audio, visual or related signal. The wall plate may include numerous signal interfaces for audio, visual or combination audio/visual application. By including all of the components into a modular package, installation and removal of the wall plate for premise wiring upgrades is enhanced.

Claims

1. A modular wall plate assembly mountable within a wall structure, said assembly comprising:

a mounting bracket defining a face thereon;

at least one signal interface extending outward from said face; and

a cable lead extending generally rearwardly from said mounting bracket, said cable lead comprising a plurality of conductive lines therein such that a proximal end of said plurality of conductive lines are in electrical communication with said at least one signal interface, and a distal end of said cable lead terminates in a modular quick-connect coupling to achieve tool-free electrical connection to a runner cable that is part of a premise wiring system such that upon modular electrical connection of said assembly to said runner cable, said at least one signal interface can carry an electronic signal to and from said runner cable, wherein the length of said cable lead is such that said quick-connect coupling defines a substantially farthest rearward projection of said assembly that is rearwardly cantilevered such that said quick-connect coupling comprises a termination with which to facilitate flexibly moveable connection to said runner cable once signal coupling is established therebetween.

2. The assembly of claim 1, further comprising a circuit board coupled to said mounting bracket to establish a permanent connection between said cable lead and said circuit board.

3. The assembly of claim 1, wherein said cable lead comprises a male distal end.

4. The assembly of claim 2, further comprising a housing coupled to said at least one of said circuit board and said mounting bracket.

5. The assembly of claim 4, wherein said housing comprises an electromagnetic shield configured to substantially enclose said circuit board.

6. The assembly of claim 1, wherein said at least one signal interface comprises a plurality of signal interfaces.

7. The assembly of claim 6, wherein said plurality of signal interfaces is selected from the group consisting of D-subminiature, BNC, RCA, 3.5 millimeter, S-video and combinations thereof.

8. The assembly of claim 1, further comprising a strain relief member disposed between said proximal end of said cable lead and said circuit board.

9. The assembly of claim 1, wherein said cable lead extends rearward such that said quick-connect coupling faces substantially away from said at least one signal interface.

10. The assembly of claim 1, wherein said circuit board is connected to said mounting bracket.

11. The assembly of claim 1, wherein the length of said cable lead is up to about eighteen inches.

12. The assembly of claim 11, wherein the length of said cable lead is up to about six inches.

13. A premise wiring system comprising:

a wall plate assembly comprising;

a modular wall plate mountable within a wall structure, said wall plate comprising;

a mounting bracket;

at least one signal interface extending outward from said mounting bracket; and

a cable lead extending generally rearwardly from said mounting bracket, said cable lead comprising a plurality of conductive lines therein such that a proximal end of said plurality of conductive lines are in electrical communication with said at least one signal interface, and a distal end of said cable lead terminates in a modular quick-connect coupling, wherein the length of said cable lead is such that said quick-connect coupling defines a substantially farthest rearward projection of said assembly; and

at least one runner cable comprising a plurality of conductive lines therein, said runner cable defining said signal source and comprising a quick-connect coupling on at least one end thereof such that upon engagement of said quick-connect coupling of said runner cable to said quick-connect coupling of said cable lead, a signal transmitted through said runner cable and said cable lead is also conveyed through said at least one signal interface, wherein said distal end of said cable lead is rearwardly cantilevered such that said quick-connect coupling comprises a flexible termination with which to facilitate moveable connection to said runner cable once signal coupling is established therebetween.

14. The premise wiring system of claim 13, further comprising a circuit board coupled to said mounting bracket, and a housing coupled to said at least one of said circuit board and said mounting bracket, said circuit board connected to said cable lead and said at least one signal interface to provide electrical communication therebetween.

15. The premise wiring system of claim 14, further comprising a gang box configured to substantially contain said wall plate assembly therein.

16. The premise wiring system of claim 13, wherein said at least one signal interface comprises a plurality of signal interfaces.

17. The premise wiring system of claim 16, wherein said plurality of signal interfaces is selected from the group consisting of D-subminiature, BNC, RCA, 3.5 millimeter, S-video and combinations thereof.

18. A method of connecting premise wiring to a wall plate assembly, said method comprising:

arranging at least one runner cable in said premise wiring to include a quick-connect coupling at a terminus thereof; and

connecting said quick-connect coupling to a complementary quick-connect coupling situated on said assembly, said assembly comprising;

a mounting bracket defining a face thereon;

at least one signal interface extending outward from said face; and

a cable lead extending generally rearwardly from said mounting bracket, said cable lead comprising a plurality of conductive lines therein such that a proximal end of said plurality of conductive lines are electrically connected with said at least one signal interface, and a distal end of said cable lead terminates in a modular quick-connect coupling such that said runner cable and said assembly can be placed in electrical communication with one another without the need for a connecting tool, said distal end of said cable lead defining a cantilevered end such that said connecting defines a substantially non-rigid joining, thereby permitting a range of flexible movement between said quick-connect coupling and said complementary quick-connect coupling.

19. The method of claim 18, further comprising permanently connecting said proximal end of said cable lead to at least one of a circuit board and said signal interface.

20. The method of claim 19, further comprising reducing tension between said wall plate assembly and said at least one cable in said premise wiring.

21. The method of claim 20, wherein said reducing tension comprises placing a strain relief device between said at least one cable in said premise wiring and said signal interface.
