Active cover plates
In one example, an active cover plate includes a faceplate, a load and a spring clip adjustable in at least one of a horizontal direction and a vertical direction with respect to the faceplate to electrically interface with a receptacle body and extract electrical power from the receptacle body to energize the load. A method for installing an active cover plate on an electrical receptacle is also provided.
1. An active cover plate comprising:
a faceplate comprising at least one detent; and
a spring clip comprising a base with at least one notch;
wherein the spring clip is adjustable with respect to the faceplate by moving the base to engage at least one detent with at least one notch.
2. The active cover plate of claim 1 , wherein the spring clip comprises a conductive portion connected to the faceplate and non-conductive portion joined to the conductive portion.

4. The active cover plate of claim 3 , wherein the non-conductive portion comprises:
a main ramp portion extending from the flexible conductive portion, wherein the main ramp portion is to guide the active cover plate over the receptacle body as the active cover plate is pushed toward the receptacle body; and
ramps extending laterally away from the main ramp portion and the flexible conductive portion, wherein the ramps are angled to guide the spring clips over screw terminals on the receptacle body when the active cover plate is moved vertically relative to the receptacle body.
5. The active cover plate of claim 3 , wherein the flexible conductive portion comprises the base and at least one reverse curve between a midpoint of the flexible conductive portion and the base.
6. The active cover plate of claim 1 , wherein the spring clip is configured to be mounted in at least two different vertical positions on the faceplate.
7. The active cover plate of claim 6 , wherein the at least one notch comprises at least one aperture in the base of the spring clip;
wherein the at least one detent comprises a number of protrusions such that by selecting a protrusion on the faceplate and placing the protrusion into the at least one aperture, the spring clip can be located in a desired vertical position on the faceplate.
8. The active cover plate of claim 7 , in which the number of protrusions comprise a plurality of posts extending from the faceplate, in which the spring clip comprises at least two apertures configured to receive at least two of the posts such that by selecting at least two posts in the linear array of posts the spring clip can be located in one of at least two predetermined vertical positions on the faceplate.
9. The active cover plate of claim 1 , in which the spring clip is adjustable after complete assembly of the active cover plate.
10. The active cover plate of claim 1 , wherein the spring clip is configured to adjust vertically with respect to the faceplate into a plurality of predetermined positions.
11. The active cover plate of claim 10 , wherein the spring clip is secured in one of the plurality of predetermined positions by the at least one detent engaging with at least one notch at each of the predetermined positions.
12. The active cover plate of claim 10 , in which:
the detent is a protrusion; and
the notch is a slot;
wherein the spring clip is secured in one of the plurality of predetermined positions by the protrusion engaging in the slot in the spring clip at each of the predetermined positions.
13. The active cover plate of claim 1 , in which the spring clip further comprises:
a head; and
a pivot interposed between the base and the head and configured to swing the head to contact a screw terminal above or below the base.
14. The active cover plate of claim 1 , wherein the spring clip is adjustable in a horizontal direction to reach screw terminals at varying depths.
15. The active cover plate of claim 14 , wherein the spring clip comprises multiple contacts at different horizontal locations along the spring clip.
16. The active cover plate of claim 15 , wherein the spring clip comprises a sliding insulator moving to cover one of the multiple contacts that is not in use.
17. The active cover plate of claim 1 , wherein the spring clip conducts electrical energy to an electrical load only at predetermined positions of the spring clip with respect to the face plate.
18. The active cover plate of claim 1 , wherein the active cover plate further comprises an intermediate device interfacing with both the receptacle body and the faceplate, wherein the intermediate device extracts power out of the receptacle body and conducts the power to the faceplate.
19. The active cover plate of claim 1 , wherein the active cover plate comprises at least three spring clips with at least one spring clip not extracting power from the receptacle body.
20. The active cover plate of claim 1 , wherein the spring clip further comprises a mechanism to rotate the spring clip into a position that is parallel to the faceplate.
21. The active cover plate of claim 1 , wherein the spring clip is adjustable vertically with respect to the face plate.
22. An active cover plate comprising:
a faceplate comprising a plurality of posts;
an electrical load; and
a spring clip adjustable in a vertical direction with respect to the faceplate to electrically interface with a receptacle body and extract electrical power from the receptacle body to energize the load, wherein the spring clip comprises:
a flexible conductive portion connected to the faceplate by a base portion with apertures;
a non-conductive portion connected to an opposite end of the flexible conductive portion,
wherein the spring clip is configured to be mounted in at least two different vertical positions along the face plate by placing the base with apertures over posts in the plurality of posts.
23. An active cover plate comprising:
a faceplate;
a spring clip;
at least one slot; and
a plurality of protrusions;
wherein the spring clip is adjustable vertical direction with respect to the faceplate by moving the spring clip to engage the at least one slot with one of the protrusions.
24. The active cover plate of claim 23 , in which the faceplate comprises the at least one slot, wherein the at least one slot comprises a groove and the spring clip comprises the at least one protrusion, wherein the at least one protrusion comprises a spring tab configured to engage with the at least one groove.
25. The active cover plate of claim 23 , wherein the spring clip is configured to be adjusted vertically with respect to the faceplate into a plurality of predetermined positions, in which the spring clip is secured in one of plurality of predetermined positions by the spring tab engaging with a groove in each of the predetermined positions.
