Abstract

A junction box mountable on a roof surface, comprising a housing unit and an enclosing unit, the housing unit and enclosing unit combining to form a waterproof assembly. The housing unit is mountable to a roof surface via a flashing having a continuous, raised waterproofing track that mates with a waterproofing recess in a bottom surface of the housing unit to create a waterproofing zone inside the housing unit. At least one bottom pass through is located within the waterproofing zone and provides a channel from the internal housing area through the roof surface.

Claims (30)

1. A junction box, comprising:

a housing unit comprising an internal housing area further having a bottom surface, the housing unit mountable to a roof surface via a flashing having a continuous, raised waterproofing track that mates with a waterproofing recess in the bottom surface to create a waterproofing zone inside the housing unit;

wherein at least one bottom pass through is located within the waterproofing zone and provides a channel from the internal housing area through the roof surface.

2. The junction box of claim 1 , wherein the waterproofing zone within the junction box protects hot, neutral, and/or grounding wires in the closed configuration.

3. The junction box of claim 1 , wherein the housing unit is adapted to connect with wiring of a solar panel.

4. The junction box of claim 1 , wherein a rubber seal is positioned between said waterproofing track and said waterproofing recess.

5. The junction box of claim 1 , wherein an enclosing unit is attached to the housing unit via a hinge unit, the hinge unit comprising a swiveling pivot.

6. The junction box of claim 5 , wherein the hinge unit includes a plurality of hinge unit joinder segments, the hinge joinder segments enabling removable attachment and detachment of the hinge unit.

7. The junction box of claim 1 , wherein a housing unit lock and an enclosing unit lock combine to secure the mountable junction box in a closed configuration.

8. The junction box of claim 7 , wherein the housing unit lock and the enclosing unit lock enable the enclosing unit to lock in a water-sealed engagement with the housing unit, thereby further preventing the entry of water into the housing unit.

9. The junction box of claim 1 , wherein the housing comprises an underside and a rubber seal thereon.

10. The junction box of claim 9 wherein the rubber seal combines with fasteners to enable a waterproof attachment of the mountable junction box.

11. A junction box, comprising:

a housing unit further comprising an internal housing area having a bottom surface;

a bracket, the bracket comprising a double flanged retainer with a depression area for securing at least one lip fastener and at least one bracket clip; and

wherein the bracket is removably connected to the housing unit and is configured to connect the housing unit to a solar panel support rail.

12. The junction box of claim 11 wherein the bracket comprises at least one lip fastener and at least one bracket clip.

13. The junction box of claim 11 , wherein a housing unit lock and an enclosing unit lock combine to secure the mountable junction box in a closed configuration, and wherein the housing unit lock and the enclosing unit lock enable the enclosing unit to lock in a water-sealed engagement with the housing unit.

14. The junction box of claim 13 , wherein the enclosing unit is attached to the housing unit via a hinge unit, the hinge unit comprising a swiveling pivot.

15. A junction box, comprising:

a housing unit attached to a rail and adapted to connect with a photovoltaic panel system, the housing unit further comprising an internal housing area and at least one bottom pass through;

a hinge unit;

a bracket and a rail, the bracket comprising at least one lip fastener and at least one bracket clip;

wherein the housing unit is mountable to a roof surface via a flashing having a continuous, raised waterproofing track that mates with a waterproofing recess in a bottom surface of the housing unit to create a waterproofing zone inside the housing unit; and

wherein the at least one bottom pass through is located within the waterproofing zone and provides a channel from the internal housing area through the roof surface.

16. The junction box of claim 15 , wherein an underside of the housing unit includes a depression waterproofing indentation and rubber seal, the waterproofing indentation preventing water infiltration through the roof while also providing structural stability to the mountable junction box.

17. The junction box of claim 16 , wherein the depression waterproofing indentation and rubber seal forms a continuous shape with no right angles.

18. The junction box of claim 15 , wherein the housing unit is adapted to connect with wiring of a solar panel.

19. The junction box of claim 15 , wherein an underside of the housing unit comprises a rubber seal.

20. The junction box of claim 19 wherein the rubber seal combines with fasteners to enable a waterproof attachment of the mountable junction box.
