Abstract

A housing for an electrical connection of a solar panel is disclosed. The housing comprises a first body having a first recess positioned along a side wall, a second body having a second recess positioned along a side wall, the second body attached to the first body to define a confined space, a bushing positioned between the first body and the second body and received in each of the first recess and the second recess, and a cable extending from an exterior of the first and second bodies through the bushing and into the confined space such that the bushing seals the confined space from the exterior.

First claim

What is claimed is:

1. A housing for an electrical connection of a solar panel, comprising:
a first body having a first recess positioned along a side wall;
a second body having a second recess positioned along a side wall, the second body attached to the first body to define a confined space;
a first cable guide positioned on an outside of the second body and having an aperture aligned with the second recess, a first gap disposed between a portion of the first cable guide having the aperture and both the side wall of the second body and the side wall of the first body along a longitudinal axis extending through the aperture and into the confined space;
a bushing positioned between the first body and the second body and received in each of the first recess and the second recess; and
a cable extending from an exterior of the first and second bodies through the aperture of the first cable guide and the bushing along the longitudinal axis and into the confined space such that the bushing seals the confined space from the exterior.

2. The housing of claim 1 , wherein a groove is formed between the first body and the second body when the first body and second body are attached.

3. The housing of claim 2 , wherein the groove extends around the confined space.

4. The housing of claim 3 , wherein a gasket is positioned in the groove.

5. The housing of claim 4 , wherein the gasket is one of a polymeric foam and a silicone seal.

6. The housing of claim 4 , wherein a portion of the bushing received in each of the first recess and second recesses has a lip extending circumferentially around the bushing.

7. The housing of claim 6 , wherein a plurality of parallel lips extends circumferentially around the portion of the bushing received in each of the first and second recesses.

8. The housing of claim 7 , wherein the plurality of parallel lips abut the second recess.

9. The housing of claim 8 , wherein the plurality of parallel lips abut the first recess.

10. The housing of claim 9 , wherein the plurality of parallel lips abut the gasket.

11. The housing of claim 1 , wherein the bushing is formed of silicone.

12. The housing of claim 1 , wherein the bushing has first and second end sections and a middle section disposed between the first and second end sections.

13. The housing of claim 12 , wherein a diameter of the middle section is less than a diameter of both the first and second end sections.

14. The housing of claim 13 , wherein a length of the middle section is equal to a length of both the first and second recesses.

15. The housing of claim 1 , wherein a second cable guide is positioned on an outside of the second body.

16. The housing of claim 15 , wherein the cable extends through the first cable guide and the second cable guide.

17. The housing of claim 16 , wherein an outer surface of the housing is mounted on a solar panel.

18. The housing of claim 17 , wherein the longitudinal axis of the cable at the first cable guide is further away from the solar panel than a longitudinal axis of the cable at the second cable guide.

19. The housing of claim 1 , wherein a portion of the bushing is disposed in the first gap such that a second gap smaller than the first gap is disposed between the first cable guide and the bushing.

20. The housing of claim 1 , wherein the first cable guide is attached to the second body only at an end of the first cable guide opposite the aperture.
