Description

Aufgrund der zunehmenden Rohstoffknappheit und Umweltbelastung durch Verwendung fossiler Energieträger wir zunehmend Sonnenenergie zur Gewinnung von elektrischem Strom verwendet. Die Technologie ist nach dem heutigen Stand der Technik jedoch relativ teuer. Aus diesem Grund, ist es von hohem Interesse kostensenkende Maßnahmen und Technologien zu entwickeln.by virtue of the increasing scarcity of raw materials and the environmental impact of use fossil energy source We increasingly use solar energy to generate electricity used. However, the technology is state-of-the-art relative expensive. For this reason, it is of high interest cost cutting activities and develop technologies.

Üblicherweise werden Photovoltaikmodule durch Modulklemme mittels sogenannter Nutmuttern oder Hammerkopfmuttern auf Montageprofilen befestigt, welche eine Nut aufweisen.Usually Are photovoltaic modules by module clamp by means of so-called Locknuts or hammerhead nuts attached to mounting profiles, which have a groove.

Bei großflächigen Photovoltaikanlagen, welche ohne weiteres aus mehreren zehntausend Photovoltaikmodulen bestehen, ist die Montagefreundlichkeit von hoher Bedeutung um Montagezeiten und -kosten einzusparen. Die oben beschriebene Methode, Nutmuttern zur Befestigung von Modulklemmen zu verwenden weist den Nachteil auf, dass nicht eindeutig gewährleistet ist, dass sich die Mutter entsprechend Ihrer Geometrie derart im Verhältnis zum Montageprofil dreht, dass Sie sich aus der Nut löst. Weiterhin ist von Nachteil, dass es bei der Montage der Module von der Montageseite her nicht möglich ist, den richtigen Sitz der Mutter zu kontrollieren.at large-area photovoltaic systems, Which easily from several tens of thousands of photovoltaic modules The ease of installation is very important for assembly times and save costs. The method described above, locknuts to use for mounting of module terminals has the disadvantage on that not clearly guaranteed is that the mother according to your geometry so in the relationship to the mounting profile turns that it releases from the groove. Farther It is disadvantageous that it is when mounting the modules from the mounting side not possible is to control the correct fit of the mother.

Die folgende Erfindung mit den im Schutzansprüchen 1–4 aufgeführten Merkmalen stellt eine Modulklemme aus einem Oberteil und einem Unterteil dar, welche durch speziell angeordnete Schlitze ein Eindrehen des Modulklemmenunterteil in einem nutförmig geschlitztem Montageprofil ermöglicht und nach dem Eindrehen eine formschlüssige, jedoch verschiebbare Verbindung ermöglicht, welche während und nach der Photovoltaikmodulmontage nicht wieder zurückgedreht werden kann, da die Seiten des Modulklemmenunterteils und Modulklemmenoberteils derart am Rahmen der Photovoltaikmodule anliegen, dass ein Ausdrehen verhindert wird. Dies ist auch beim Anziehen der Schraube, welche mittels der Modulklemme und dem Modulklemmenhalter das Photovoltaikmodul am Montageprofil befestigt, der Fall. Denkbar ist auch, anstatt des Gewindes im Modulklemmenhalter eine extra Mutter zu verwenden. Das Modulklemmenoberteil kann auch derart geformt sein, dass sich die Klemme als Modulabschlussklemme eignet.The The following invention with the features listed in claims 1-4 provides protection Module clamp of an upper part and a lower part, which by specially arranged slots screwing the module clamp base in a groove shape Slotted mounting profile allows and after screwing a positive, but movable Allows connection which during and not turned back after photovoltaic module assembly can be as the sides of the module clamp base and module clamp top lie so on the frame of the photovoltaic modules that a turning out is prevented. This is also when tightening the screw, which by means of the module clamp and the module clamp holder the photovoltaic module attached to the mounting profile, the case. It is also possible, instead of the thread in the module clamp holder to use an extra nut. The Module terminal shell can also be shaped so that the Terminal is suitable as module termination terminal.

Ein Ausführungsbeispiel der Erfindung wird anhand der 1–11 erläutert. Es zeigen:An embodiment of the invention will be described with reference to 1 - 11 explained. Show it:

In den 1–7 sind die Modulklemmenunterteil 11 mit den Schlitzen, lang 12 und Schlitzen, kurz 13 dargestellt, welche in der Montageprofil 20 derart eingeführt und an schließlich gedreht werden, dass sich die Schenkel 22 des Montageprofils 20 formschlüssig in die Schlitze derart eindrehen, dass das Modulklemmenunterteil 11 mittels Modulklemmenoberteil 10 und Schraube 15 den Rahmen 31 und damit das Photovoltaikmodul 30 kraftschlüssig am Montageprofil 20 festklemmen. Die längeren Schlitze 12 ermöglichen ein Eindrehen des Modulklemmenunterteils, wobei die maximal benötigte Tiefe bei 45° Drehung nach dem Einführen des Modulklemmenunterteils erreicht wird, wie in 4 dargestellt. Die kurzen Schlitze 12 verhindern ein Verrutschen des Modulklemmenunterteils, wie in 5 zu sehen.In the 1 - 7 are the module clamp base 11 with the slits, long 12 and slits, in short 13 shown which in the mounting profile 20 so introduced and finally turned, that the thighs 22 of the mounting profile 20 screw in the slots in a form-fitting manner such that the module clamp base 11 by means of module terminal shell 10 and screw 15 the frame 31 and thus the photovoltaic module 30 non-positively on the mounting profile 20 Clamp. The longer slots 12 allow the module clamp base to be screwed in to reach the maximum required depth at 45 ° rotation after insertion of the module clamp base, as in 4 shown. The short slots 12 prevent slippage of the module clamp base, as in 5 to see.
