Abstract

In various representative aspects, the present invention relates generally to providing an apparatus for securing a solar panel module to a solar panel rail guide structure. More specifically, the invention relates to providing an end clamp that mounts a bottom flange of a solar panel module to a solar panel rail guide structure. The end clamp does not require any tools for insertion. It mechanically fastens and electrically bonds the solar panel module to a solar panel rail guide structure.

First claim

What is claimed is:

1. A clamping device for joining and electrically bonding a solar panel to a solar panel rail guide comprising:
A. a handle comprising:
i. a front end, and
ii. at least one rear end,
iii. the front end comprising a channel extending between a top surface and a bottom surface of the front end;

B. at least one raised portion positioned at the bottom surface of the front end to provide electrical bonding between the clamping device and the solar panel; and
C. a post structure, comprising:
i. an upper end,
ii. a lower end,
iii. a shaft, and
iv. a radial extension at the lower end,
v. the post structure being coupled to the front end and passes through the channel, wherein the radial extension of the post structure comprises at least one serration that faces towards the bottom surface of the front end to provide electrical bonding between the solar panel rail guide and the clamping device.

2. The clamping device of claim 1 , wherein the radial extension at the lower end of the post structure is removable or permanently affixed bottom washer.

3. The clamping device of claim 1 , wherein the upper end of the post structure further comprises a top washer, wherein the post structure is configured to couple with the top washer.

4. The clamping device of claim 1 , wherein the channel comprises a base.

5. The clamping device of claim 3 , wherein the post structure comprises of a spring coupled between the top washer and the base.

6. The clamping device of claim 3 , wherein the top washer is configured to compress the spring when the rear end of the handle is moved to a locked position.

7. The clamping device of claim 5 , wherein the spring comprises at least one bearing configured to create a clamping force when compressed.

8. The clamping device of claim 7 , wherein the bearing comprises a disc spring or a washer.

9. The clamping device of claim 1 , wherein the rear end of the handle is configured to provide tactile feedback on moving to a locked position.

10. The clamping device of claim 1 , wherein the raised portion comprises a plurality of detachable bonding pins.

11. A clamping arrangement comprising:
A. a solar panel comprising a bottom flange;
B. a solar panel rail guide comprising side flanges forming a top channel; and
C. a clamping device comprising:
i. a handle comprising:
a. a front end, and
b. at least one rear end;

ii. at least one raised portion provided at the front end; and
iii. a post structure coupled to the handle at the front end,
iv. the post structure comprising:
a. a lower end,
b. a radial extension at the lower end, and
c. at least one serration on the radial extension extending towards the handle;

D. wherein the solar panel is positioned along a top axis of the side flanges of the solar panel rail guide and the post structure is positioned into the top channel of the solar panel rail guide; and
E. wherein the serration on the radial extension engages with the top channel to electrically bond the clamping device with the solar panel rail guide and the raised portion engages with the bottom flange of the solar panel to electrically bond the clamping device with the solar panel.

12. The clamping arrangement of claim 11 , wherein the radial extension at the lower end of post structure is removable or permanently affixed bottom washer.

13. The clamping arrangement of claim 11 , wherein the raised portion comprises a plurality of detachable bonding pins.

14. The clamping arrangement of claim 11 , wherein the solar panel rail guide comprises an electrically conducting material and further comprises a surface oxidation layer on the side flanges.

15. The clamping arrangement of claim 11 , wherein the solar panel rail guide further comprises a surface oxidation layer such that the serration penetrates the surface oxidation layer on moving the rear end of the handle into a locked position.

16. The clamping arrangement of claim 11 , wherein the bottom flange of the solar panel is covered partially by the front end of the handle when positioned above the bottom flange of the solar panel.

17. The clamping arrangement of claim 11 , wherein the bottom flange of the solar panel is an electrically conducting material further comprising a surface oxidation layer.

18. The clamping arrangement of claim 11 , wherein the raised portion penetrate the surface oxidation layer of the bottom flange of the solar panel rail guide on moving the rear end of the handle into the locked position.
