Connector for a solar module
In order to deliver the current generated by means of photovoltaic solar elements, the invention proposes a connector for a solar module that is accommodated in a connector housing and can be connected to the solar elements. The solar elements are interconnected by means of flat connecting lines and embedding in a translucent sandwich panel. The current is delivered through an opening in one of the sheets of the sandwich panel by means of springable contact elements that are in electric contact with the connecting lines of the solar elements.
1. A solar module connector for connecting electric connecting lines of photovoltaic solar elements embedded in a translucent plastic layer sandwiched between inner and outer sheets comprising, in combination,
a contact plate with reinforcing elements for contacting the connecting lines,
a contact housing with a cover plate having power carrying contact elements, wherein the contact elements comprise outwardly fixed contact pins centrally arranged on an arc section of a spring element, and have a plurality of pyramid-shaped-points for contacting and pressing into the connecting lines,
a connector housing containing said contact housing, and
a connector plug for connection to a service cable.
2. The solar module connector according to claim 1 , wherein the reinforcing elements are u-shaped and partially encompass the connecting lines, and wherein the reinforcing elements are provided with hooks that engage on an undercut within a rectangular recess in the contact plate.
3. The solar module connector according to claim 1 , wherein the contact plate is fixed within a depression formed in the translucent plastic layer.
4. The solar module connector according to claim 1 , wherein the spring elements each comprise two terminal ends that are respectively guided into a longitudinal slot of the cover plate for electrically connecting a printed circuit board.
5. The solar module connector according to claim 4 , wherein the cover plate is interlocked with the contact housing, and the contact pins of the contact elements are guided in guide bores formed in the contact housing.
6. The solar module connector according to claim 1 , wherein the contact housing, contact elements, cover plate and a printed circuit board are assembled as a unit and inserted into a rectangular opening in the connector housing.
7. The solar module connector according to claim 6 , wherein the assembled unit is fixed on the inner sheet by a double-sided adhesive foil which covers the contact plate recess.
8. The solar module connector according to claim 1 , wherein the connector plug is separably connected to the connector housing.
9. The solar module connector according to claim 1 , wherein the connector housing comprises a lower housing part and a hinged housing cover.
