Junction box for connecting a solar cell, electrical diode, guiding element and fixing means
View Patent ↗A junction box for connecting a solar cell, having a housing; a diode; and a conductive foil strip electrical contact. The housing includes a base plate with a receiving passageway that extends along a slide direction. The receiving passageway opens along an upper side of the base plate through a receiving slot.
1. A junction box for connecting a solar cell, comprising:
a housing;
a diode; and
a conductive foil strip electrical contact,
wherein the housing further includes a base plate with a receiving passageway that extends along a slide direction, the receiving passageway opens along an upper side of the base plate through a receiving slot.
2. The junction box according to claim 1 , wherein the foil strip is secured to the housing.
3. The junction box according to claim 2 , wherein the foil strip is fixed to the housing by a pin or clip.
4. The junction box according to claim 3 , wherein the pin or clip protrudes from the foil strip.
5. The junction box according to claim 1 , further comprising a guide being connected to the housing and having a guiding surface.
6. The junction box according to claim 5 , wherein the foil strip extends over the guiding surface.
7. The junction box according to claim 6 , wherein the foil strip is secured to the guide.
8. The junction box according to claim 5 , wherein the guide is removably connected to the housing.
9. The junction box according to claim 8 , wherein the guide is slidable.
10. The junction box according to claim 5 , wherein the guide has a partially spherical guiding surface, the guiding surface supports the foil strip.
11. The junction box according to claim 1 , wherein the receiving slot extends along the slide direction, the receiving slot has a smaller width than the receiving passageway along a cross section of the base plate that is perpendicular to the slide direction.
12. The junction box according to claim 11 , wherein the guide further includes a foot plate that is positioned in the receiving passageway, the foot plate is broader than the receiving slot and directs the guide in the receiving passageway in a slidable manner along the slide direction.
13. The junction box according to claim 1 , further comprising a conductor of the solar cell wherein the conductor connects to the foil strip.
14. The junction box according to claim 13 , wherein the conductor is secured to the guide by a clamp.
15. The junction box according to claim 14 , wherein the clamp secures to the guide and electrically connects to the foil strip.
16. The junction box according to claim 15 , wherein the clamp has a conductor element that connects to an electrical contact point.
17. The junction box according to claim 16 , wherein the conductor element is positioned along and secured to the guide wherein the conductor element contacts the foil strip along the guide and extends to a contact point.
18. The junction box according to claim 1 , further comprising a fixing mechanism for securing the electrically conductive foil strip to a guide.
19. The junction box according to claim 18 , wherein the fixing mechanism is a clamp.
20. The junction box according to claim 19 , wherein the clamp secures the foil strip on a guiding surface of the guide.
21. The junction box according to claim 20 , wherein the clamp has an Ω (omega)-shape.
