Connecting box of a solar panel with a cooling structure
The invention relates to a receptacle ( 1 ) particularly suitable for wiring one or more solar cells ( 81 ). The receptacle ( 1 ) comprises a housing ( 10 ) and a connecting shaft ( 60 ) that can be separately closed by a cover ( 63 ). The receptacle ( 1 ) is raised from the back side of the solar panel ( 80 ).
1. A connecting box ( 1 ) having a housing ( 10 ), for connection of at least one electronic component ( 51 ), which is arranged on a printed circuit board ( 50 ) in the interior of the housing ( 10 ) to electrical connections of a solar panel ( 80 ), the connecting box comprising:
a connecting slot ( 60 ) defined by a circumferential frame ( 62 ) having an essentially O-shaped cross section which opens at a lower end into a circumferential mounting surface ( 69 );
a projecting mounting cap ( 30 ) positioned with respect to the housing ( 10 ) for attachment of the connecting box ( 1 ) to a surface of the solar panel ( 80 ); and
a rear wall ( 19 ) of the housing ( 10 ), when in a fitted state, positioned at a distance (A) from the solar panel ( 80 ) resulting in convectional cooling of the housing ( 10 ).
2. The connecting box ( 1 ) of claim 1 , wherein the connecting slot ( 60 ) is fitted peripherally to the housing ( 10 ).
3. The connecting box ( 1 ) of claim 1 , wherein the mounting cap ( 30 ) is formed from a plurality of parts.
4. The connecting box ( 1 ) of claim 1 , wherein the mounting cap ( 30 ) surrounds the connecting slot.
5. The connecting box ( 1 ) of claim 1 , wherein the mounting cap ( 30 ) includes at least one adhesive surface ( 32 , 33 ) for holding an adhesive and/or a double-sided adhesive tape ( 34 ).
6. The connecting box ( 1 ) of claim 1 , further comprising:
air guide plates ( 23 ) which are arranged on the rear wall ( 19 ) of the housing.
7. The connecting box ( 1 ) of claim 6 , wherein the air guide plates ( 23 ) are designed such that, in the fitted state, they are used to support the housing ( 10 ) with respect to the solar panel ( 80 ).
8. The connecting box ( 1 ) of claim 1 , wherein, at least in places, the housing ( 10 ) rests closely on the printed circuit board ( 50 ) such that heat which is created is transported outwards through the housing ( 10 ).
9. The connecting box ( 1 ) of claim 8 , wherein the printed circuit board ( 50 ) is a stamped grid.
10. The connecting box ( 1 ) of claim 1 , wherein the housing ( 10 ) further comprises:
a housing lower part ( 20 ) and a housing upper part ( 40 ) which closely surround the printed circuit board ( 50 ) and the at least one electronic component ( 51 ).
11. The connecting box ( 1 ) of claim 1 , wherein the housing ( 10 ) is formed integrally by insert molding of the printed circuit board ( 50 ) and the at least one electronic component ( 51 ).
12. The connecting box ( 1 ) of claim 1 , wherein the connecting slot ( 60 ) is suitable for holding an encapsulation medium.
