Abstract

An active cover plate is disclosed. The active cover plate may include a face plate, a back plate; an electrical load, at least one clip may extend rearward from the face plate and a wall may extend rearward from the back plate, where the wall may cover at least a part of a rear of the clip, and an electrical connection may connect the electrical load to the clip.

Claims

1. An active cover plate comprising:

a face plate;

a back plate;

an electrical load;

at least one clip extending rearward from the face plate, the clip comprising;

a base; and

a contact;

a free standing insulating wall extending rearward from the back plate, wherein the free standing insulating wall shields at least part of a rear of the clip and wherein the free standing insulating wall is configured to stand with a space between it and the clip when the clip is not deformed and to contact the clip when the clip is deformed through contacting a screw terminal; and

an electrical connection connecting the electrical load to the contact of the clip; and

wherein the clip is configured to contact the screw terminal of an electrical receptacle when the active cover plate is placed over the electrical receptacle;

wherein the clip extending from the base, the clip comprises an inwardly angled portion connected to the base and wherein the inwardly angled portion extends toward a center of the face plate, the contact comprising a bent portion of the clip above the inwardly angled portion, and an outwardly angled portion above and connected to the bent portion;

wherein the outwardly angled portion extends toward an edge of the face plate; and

wherein the bent portion is a most inwardly extending portion of the clip which is nearest to the center of the face plate and wherein the bent portion is configured to contact the screw terminal.

2. The active cover plate of claim 1, wherein the base of the clip is between the back plate and the face plate.

3. The active cover plate of claim 1, wherein the face plate comprises posts extending rearward and wherein the back plate comprises apertures to accept the posts.

4. The active cover plate of claim 3, wherein the base of the clip comprises apertures to accept the posts.

5. The active cover plate of claim 4, wherein the posts secure the base of the clip between the face plate and the back plate.

6. The active cover plate of claim 1, wherein the free standing insulating wall is interposed between the clip and an edge of the face plate.

7. The active cover plate of claim 1, wherein the free standing insulating wall is an injection molded feature of the back plate.

8. The active cover plate of claim 1, wherein the free standing insulating wall is a flexible integrally molded component of the back plate, in which the back plate connects to the face plate.

9. The active cover plate of claim 1, wherein the free standing insulating wall is located between the clip and an exterior edge of the face plate.

10. The active cover plate of claim 1, wherein the free standing insulating wall is an integral part of the back plate and is shorter than the clip.

11. The active cover plate of claim 1, wherein the clip comprises a bent metal strip.

12. The active cover plate of claim 1, wherein the electrical connection comprises an extension of the base of the clip.

13. The active cover plate of claim 12, wherein the base further comprises apertures to accept posts extending rearward from the face plate, wherein the posts position the base of the at least one clip on the face plate.

14. The active cover plate of claim 1, wherein the back plate comprises apertures to accept the posts, wherein the base is retained between the back plate and the face plate.

15. The active cover plate of claim 1, wherein the contact, base and electrical connection comprise a formed piece of sheet metal.

16. The active cover plate of claim 1, wherein the electrical connection, base and contact are formed from a single piece of sheet metal, the electrical connection comprising an aperture to accept a post extending from the face plate and wherein the electrical connection is between the face plate and back plate.

17. An active cover plate comprising:

a faceplate comprising posts extending rearward from the faceplate;

a pair of clips extending rearward from the faceplate to interface with opposing screw terminals of an outlet receptacle body, wherein each of the pair of clips comprise a contact configured to electrically contact one of the opposing screw terminals; and

a back plate, wherein each of the pair of clips fits over a subset of the posts extending rearward from the faceplate and the back plate fits over the posts to retain the pair of clips between the faceplate and the back plate;

wherein at least one of the pair of clips contact a wall when the pair of clips are bent outward by the opposing screw terminals wherein the wall comprises an interior wall of an electrical receptacle box; and

wherein each of the pair of clips is configured to contact the screw terminal when the active cover plate is placed over the electrical receptacle;

wherein the each of the pair of clips extends from the base;

each of the pair of clips comprises an inwardly angled portion connected to the base and wherein the inwardly angled portion extends toward a center of the face plate, the contact comprising a bent portion of each of the pair of clips above the inwardly angled portion, and an outwardly angled portion above and connected to the bent portion;

wherein the outwardly angled portion extends toward an edge of the face plate; and

wherein the bent portion and wherein the bent portion is a most inwardly extending portion of each of the pair of clips which is nearest to the center of the face plate and wherein the bent portion is configured to contact the screw terminal.

18. The active cover plate of claim 17, further comprising a second wall extending from the active cover plate.

19. The active cover plate of claim 18, wherein the second wall is shorter than the pair of clips.

20. The active cover plate of claim 19, wherein the pair of clips are configured to extend over the second wall.

21. An active cover plate for connection to an electrical receptacle, the active cover plate comprising:

a face plate;

a spring clip configured to extract power from a terminal on a side of the electrical receptacle body; and

a free standing insulating wall located between the spring clip and an exterior edge of the face plate wherein the free standing insulating wall shields at least part of a rear of the spring clip and wherein the free standing insulating wall is configured to stand with a space between it and the spring clip when the spring clip is not deformed and to contact the spring clip when the spring clip is deformed through contacting a screw terminal; and

wherein the spring clip is configured to contact the screw terminal when the active cover plate is placed over the electrical receptacle;

wherein the spring clip extending from the base, the spring clip comprises an inwardly angled portion connected to the base and wherein the inwardly angled portion extends toward a center of the face plate, the contact comprising a bent portion of the spring clip above the inwardly angled portion, and an outwardly angled portion above and connected to the bent portion;

wherein the outwardly angled portion extends toward an edge of the face plate; and

wherein the bent portion is a most inwardly extending portion of the spring clip which is nearest to the center of the face plate and wherein the bent portion is configured to contact the screw terminal.

22. The active cover plate of claim 21, further comprising an electrical conductor, at least one circuit, and a back plate, wherein the electrical conductor connects the spring clip to the circuit and the electrical conductor is sandwiched between the face plate and the back plate.

23. The active cover plate of claim 22, wherein the free standing insulating wall is an integral part of the back plate.

24. The active cover plate of claim 21, wherein the free standing insulating wall does not extend as far from the back plate as the spring clip.
