Abstract

A solar grounding connector for capturing a wire. The connector includes a base and a stuffer. The base is made from a conductive metal and includes a base plate. The base plate includes means for assembling the base to a solar panel. A pair of opposed sidewalls extend at an angle from the base plate, each sidewall including a slot of preselected size. The stuffer is pivotably mounted to the base. The stuffer includes a top surface, and a pair of opposed sidewalls extending from the stuffer top surface toward the base plate. Each stuffer sidewall has a slot corresponding to the slot in the base sidewall, each opposed stuffer sidewall being adjacent to a base sidewall when engaged. The slot in the stuffer sidewalls urge a wire against the corresponding slots in the base sidewalls, exerting a force on the wire sufficient to establish electrical contact between the wire and the base. The grounding connector also includes means for fastening the stuffer with respect to the base. The solar grounding connector is attached to a solar panel frame, while the wire has one end connected to ground.

Claims

1. A connector for capturing a wire, comprising:

a base, the base further comprising a conductive metal and having,

a base plate, the base plate including means for assembling the base to a panel,

a pair of opposed sidewalls extending at an angle from the base plate, each sidewall including a plurality of slots arranged as opposed pairs of preselected size, each opposed pair being of a different size so that each base can accommodate a plurality of wires of preselected sizes in the slots;

a stuffer, the stuffer mounted to the base, the stuffer further comprising,

a top surface,

a pair of opposed sidewalls extending from the stuffer top surface toward the base plate, each stuffer sidewall having slots corresponding to the slots in the base sidewalls, each opposed stuffer sidewall being adjacent to a base sidewall; and

means for fastening the stuffer with respect to the base,

wherein the slot in each of the stuffer sidewalls urges the wire against the corresponding slot in the base sidewalls, exerting a force on the wire sufficient to establish electrical contact between the wire and the base.

2. The connector of claim 1 wherein the opposed sidewalls of the base plate extend at an angle of about 90°

toward the stuffer.

3. The connector of claim 1 wherein the pair of base plate sidewall slots include a first, lower U-shaped opening and a second opening having a width greater than the first, lower U-shaped opening.

4. The connector of claim 1 wherein the plurality of opposed pairs of slots can accommodate at least two wire sizes selected from the group of wire sizes consisting of 4 gauge, 6 gauge, 8, gauge, 10 gauge, 12 gauge, 14, gauge, 16 gauge 18 gauge and 20 gauge.

5. The connector of claim 1 wherein the means for fastening the base plate to the panel includes an aperture in the base plate and a self-tapping aluminum screw.

6. The connector of claim 1 wherein the means of fastening the stuffer to the base includes a detent assembly wherein the detent assembly includes a detent node in one of the base and the stuffer and a mating detent slot in the other of the base and the stuffer.

7. The connector of claim 1 wherein the stuffer further includes a lever extending from the stuffer top surface.

8. The connector of claim 1 wherein the opposed sidewalls of the stuffer top surface extend at an angle of about 90°

toward the base.

9. The connector of claim 1 wherein the opposed sidewalls of the stuffer top surface are separated by a distance different than the opposed sidewalls of the base plate so that the opposed sidewalls of the stuffer do not interfere with the opposed sidewalls of the base plate when the stuffer is in the engaged position.

10. The connector of claim 1 wherein the opposed sidewalls of the stuffer are separated by a distance less than the distance separating the opposed sidewalls of the base plate.

11. The connector of claim 1 wherein the stuffer is pivotally mounted to the base.

12. The connector of claim 1 wherein the base is comprised of metal.

13. The connector of claim 12 wherein the base is comprised of stamped metal.

14. The connector of claim 12 wherein the base is comprised of a tin-plated copper alloy.

15. The connector of claim 1 wherein the stuffer is comprised of an insulative material.

16. The connector of claim 15 wherein the insulative material comprising the stuffer includes a resilient plastic.

17. A grounding system for a solar module comprising:

a solar module having a frame;

a wire of preselected size having an end connected to ground;

a grounding clip, the grounding clip attached to the frame of the solar module, the grounding clip further comprising

a base, the base further comprising a conductive metal and having,

a base plate, the base plate including means for assembling the base to a panel,

a pair of opposed sidewalls extending at an angle from the base plate, each sidewall including a plurality of slots arranged as opposed pairs of preselected size, each opposed pair being of a different size so that each base can accommodate a plurality of wires of preselected sizes in the slots,

a stuffer, the stuffer mounted to the base, the stuffer further comprising,

a top surface,

a pair of opposed sidewalls extending from the stuffer top surface toward the base plate, each stuffer sidewall having slots corresponding to the slots in the base sidewalls, each opposed stuffer sidewall being adjacent to a base sidewall,

means for fastening the stuffer with respect to the base;

means for fastening the grounding clip to the solar module; and

wherein the wire of preselected size extends through the slots in each of the base sidewalls, the wire contacted by the stuffer, urging the wire into the slots to establish electrical contact between the wire and the base.

18. The grounding system for a solar module of claim 17 wherein the means for fastening the grounding clip to the solar module includes an aperture in the base plate and a self-tapping aluminum screw that extends into the solar module frame.

19. The grounding system for a solar module of claim 17 wherein the self-tapping aluminum screw extends into and through the solar module frame.
