Connecting box for connecting to a solar panel
View Patent ↗A connecting box with a printed circuit board is described which has electrical components electrically connected to conductor rails of the connecting box. The printed circuit board is preferably held in the connecting box by an adhesive layer. Simple assembly and disassembly of the components is possible as a result of the use of the printed circuit board. In addition, the heat generated in the components can be better dissipated via the printed circuit board.
1. A connecting box for connecting to a solar panel comprising:
a housing in which an opening is provided for feeding electric lines of the solar panel;
conductor rails having contact elements located on opposite sides thereof, the contact elements located inside the housing for connecting to the electric lines;
electrical components electrically connected to the contact elements through contact regions of the conductor rails, the components being arranged on a printed circuit board and the printed circuit board being held in the housing; and
each of the conductor rails having a cover with at least one opening through which access is provided to the contact regions of the conductor rails, the cover having a bearing surface receiving the printed circuit board such that terminal pins of the printed circuit board are guided through the opening to the contact regions.
2. The connecting box according to claim 1 , wherein the contact element comprises a holding recess, the printed circuit board comprises a holding element, and the holding element is inserted in the holding recess to secure the printed circuit board.
3. The connecting box according to claim 1 , wherein the printed circuit board is held in the connecting box by an adhesive layer.
4. The connecting box according to claim 1 , wherein the components are arranged on the lower side of the printed circuit board, and the components are arranged between the contact elements.
5. The connecting box according to claim 3 , wherein the adhesive layer is heat conducting.
6. The connecting box according to claim 3 , wherein an adhesive foil is arranged as the adhesive layer.
7. The connecting box according to claim 3 , wherein the adhesive layer is arranged between the printed circuit board and the housing.
8. The connecting box according to claim 3 , wherein the adhesive layer is arranged between the printed circuit board and the covers.
