Abstract

In various representative aspects, an assembly for connecting and electrically bonding two solar panel rail guides is provided. More specifically, the assembly provides a novel and improved inner rail used as a splice that slides within the two solar panel rail guides and includes a serrated screw that is pre-installed within the splice. When installed, the two rail guides are brought together along the splice and meet at the point where the screw is located, the screw can then be tightened so that the serrations penetrate surface treatment layers on each of the rail guides so that the solar panel rail guides are secured and electrically coupled to each other. An alternate embodiment utilizes the inner splice to join two solar panel rail guides by sliding the splice within the inner contour of two solar panel rail guides, and utilizing a pair of bonding pins to electrically bond the splice and the two solar panel rail guides. A stop pin inserted into the splice provides a tactile connection point where the two solar panel guides can be joined together.

First claim

What is claimed is:

1. An assembly for joining and electrically bonding a pair of solar panel rail guides comprising:
a. a splice comprising:
i. a stop pin comprising a protrusion that extends outward from the splice; and
ii. first and second bonding pins such that each pin is positioned on opposite sides of the stop pin, wherein each of the first and second bonding pins comprises a raised portion that extends outward from each bonding pin that is capable of penetrating an oxidation layer on the surface of the solar panel rail guide when the splice is inserted into either of the solar panel rail guides.

2. The assembly of claim 1 wherein the protrusion of the stop pin precludes the splice from being inserted into either of the solar panel rail guides beyond the location of the protrusion.

3. The assembly of claim 1 wherein the protrusion of the stop pin is a flange aligned perpendicular to the direction of the movement of the splice when it is inserted into either of the solar panel rail guides.

4. The assembly of claim 1 wherein the raised portion of the bonding pins is a flange aligned parallel to the direction of the movement of the splice when it is inserted into either of the solar panel rail guides.

5. The assembly of claim 1 wherein the bonding pins provide sufficient friction to the solar panel rail guide when they have penetrated the oxidation layer on the solar panel rail guide so that the solar panel rail guide remains stationary when the splice is inserted to the location of the stop pin.

6. The assembly of claim 1 wherein the bonding pins are inserted on one end of the bonding pins into the splice.

7. The assembly of claim 1 wherein the stop pin is inserted on one end of a tactile feedback element into the splice.

8. An assembly for joining and electrically bonding a pair of objects comprising:
a. a pair of solar panel rail guides;
b. a splice comprising:
i. a stop pin comprising a protrusion that extends outward from the splice; and
ii. first and second bonding pins such that each pin is positioned on opposite sides of the stop pin, wherein each of the first and second bonding pins comprises a raised portion that extends outward from each bonding pin that is capable of penetrating an oxidation layer on the surface of the solar panel rail guide when the splice is inserted into either of the solar panel rail guides.

9. The assembly of claim 8 wherein the protrusion of the stop pin precludes the splice from being inserted into either of the solar panel rail guides beyond the location of the protrusion.

10. The assembly of claim 8 wherein the protrusion of the stop pin is a flange aligned perpendicular to the direction of the movement of the splice when it is inserted into either of the solar panel rail guides.

11. The assembly of claim 8 wherein the raised portion of the bonding pins is a flange aligned parallel to the direction of the movement of the splice when it is inserted into either of the solar panel rail guides.

12. The assembly of claim 8 wherein the bonding pins provide sufficient friction to the solar panel rail guide when they have penetrated the oxidation layer on the solar panel rail guide so that the solar panel rail guide remains stationary when the splice is inserted to the location of the stop pin.

13. The assembly of claim 8 where in the bonding pins are inserted on one end of the bonding pins into the splice.

14. The assembly of claim 8 wherein the stop pin is inserted on one end of the tactile feedback element into the splice.

15. The assembly of claim 8 wherein the shape of the splice substantially conforms to the shape of an opening within the solar panel rail guides.
