Abstract

The present invention is directed to a covering for a clamping assembly used to connect and ground solar panel modules to a mounting rail. The covering comprises a sleeve including an outer cover for connecting to the solar panel module and a connector shaped to be contained within the outer cover and connected to the outer cover through two or more flanges. The connector has an opening there through to receive a female member of the clamping assembly.

First claim

What is claimed is:

1. A clamping assembly, the assembly comprising:
a. an electrically conductive solar panel frame comprising a surface treatment layer;
b. a rail guide comprising a channel further comprising a surface treatment layer;
c. an electrically conductive clamp comprising:
i. a nut having an enlarged top flange portion comprising a bottom surface, the bottom surface defining a first raised portion configured to engage the surface treatment layer of the solar panel frame,
ii. a fastener having an enlarged bottom head portion comprising a top surface defining a second raised portion configured to penetrate the surface treatment layer of the channel of the rail guide, and
iii. a connecting portion between the top flange portion and the bottom head portion comprising a first part comprising a threaded shaft of the fastener rotatably engaging a second part comprising a threaded cylindrical portion of the nut, whereby the rotation of the first part in threaded relation to the second part adjusts a distance between the top flange portion and the bottom head portion; and
d. an electrically conductive sleeve, the sleeve having an outer cover having a longitudinally-extending sidewall opening, and a connector concentrically disposed within and coupled to the outer cover, the connector having a longitudinally-extending sidewall opening aligned with the sidewall opening of the outer cover and forming an inner surface comprised of attached resilient support members configured to removably attach the sleeve to the clamping assembly connecting portion via the sidewall openings by coupling in a direction perpendicular to the connecting portion, an upper end of the sleeve engaging the bottom surface of the top flange portion, a lower end of the sleeve configured to engage the rail guide, and wherein the first raised portion penetrates the upper end of the sleeve.

2. The clamping assembly of claim 1 wherein a clockwise rotation of the first part of the connecting portion in relation to the second part of the connecting portion provides a clamping force upon the solar panel frame and the sleeve.

3. The clamping assembly of claim 2 wherein the sleeve resists the clamping force.

4. The clamping assembly of claim 1 wherein the solar panel frame occupies a first side of the clamping assembly.

5. The clamping assembly of claim 1 wherein the sleeve occupies a second side of the clamping assembly opposite the solar panel frame.

6. The clamping assembly of claim 1 wherein an electrical bond is created between the solar panel frame and the rail guide.

7. The clamping assembly of claim 6 wherein the channel comprises an upper opening portion and a lower opening portion the lower opening portion being larger than the upper opening portion.

8. The clamping assembly of claim 7 wherein the bottom head portion comprises a length that is larger than its width.

9. The clamping assembly of claim 8 wherein the bottom head portion width is smaller than the upper opening portion.

10. The clamping assembly of claim 1 wherein the first part of the connecting portion is integral with the bottom head portion.

11. The clamping assembly of claim 1 wherein the second part of the connecting portion is integral with the top flange portion.

12. The clamping assembly of claim 1 wherein a length of the sleeve and a height of the solar panel frame are equal.
