Abstract

The present invention relates to a device for easy, rapid, lasting simultaneous, corrosion-resistant and reliable connection, not requiring special tools, of one or more electrical conductors to solar elements (2) having high contact pressures, bulky contact surfaces and high extraction force and which are fixed on roofing or facade elements. This is done by a rotational eccentric element, e.g. an oval breaker (20), that opens simultaneously during its rotation at least two spring clamps of a connecting element, which is configured as a connector (6, 13) or a socket (24, 27). The shape of the connecting elements greatly excludes any false polarization. The connections can be easily detached and reestablished from the top of the solar element by using a long tool, for instance, a screw driver.

Description

Klemmvorrichtung zur Verbindung elektrischer Anschlüsse von SolarelementenClamping device for connecting electrical connections of solar elements
Die vorliegende Erfindung betrifft eine Vorrichtung zum gleichzeitigen Anschluss von zwei oder mehreren elektrischen Leitern an die Anschlüsse von Solarelementen, die mindestens ein Bedienungselement enthält, mit welchem die Anschlüsse auf einfache Weise erstellt und auch wieder gelöst werden können, nach dem Oberbegriff des Patentan- spruchs 1.The present invention relates to a device for the simultaneous connection of two or more electrical conductors to the connections of solar elements, which contains at least one operating element with which the connections can be easily created and also released again, according to the preamble of patent claim 1 .
Vorrichtungen dieser Art sind als schraubenlose Klemmvorrichtungen für den Anschluss von Leitern aus DE 27 06 482 C2 bekannt. Ebenfalls bekannt, beispielsweise aus DE 42 39 480 AI, sind Federkraftklemmen mit Betätigungsdrücker zum Oeffnen der Klemmstellen. Der Betätigungsdrücker dieser Federkraftklemme bewegt sich dabei in der gleichen Ebene wie die dadurch geöffneten Andruckfedern. Dies erweist sich insbesondere dann als Nachteil, wenn als Bedachungsoder Fassadenelemente ausgebildete Solarelemente, wie sie beispielsweise in der Patentanmeldung CH 2318/96 beschrieben sind, verlegt und elektrisch - in Serie oder parallel - miteinander verbunden werden sollen. In diesem Fall sind es die beiden Leiter mit dem positiven und dem negativen Pol eines Solarelements, welche mit den An- Schlüssen des ihm beispielsweise seitlich unmittelbar benachbarten Solarelelements verbunden werden sollen. Um die Klemmvorrichtung vor der Witterung zu schützen, wird diese sinnvollerweise unterhalb des Bedachungselements respektive des Fassadenelements angebracht. Dies bedingt eine speziell flache Bauweise der Klemmvorrichtung, was bei der oben beschriebenen Klemmvorrichtung nicht gegeben ist. Ein zweiter Nachteil dieser Klemmvorrichtungen besteht darin, dass für jeden einzelnen Leiter ein separater Betätigungsdrücker bedient werden uss. Ein weiterer Nachteil liegt darin, dass die Betätigungsdrücker, beispielsweise mit einem Schraubenzieher, im wesentlichen parallel zur Dachebene bedient werden müssten. Alle diese Nachteile stehen einer zeiteffizienten Verlegung der als Bedachungselemente ausgebildeten Solarelemente durch einen Dachdecker entgegen. Dies gilt entsprechend auch für als Fassadenelemente ausgestaltete Solarelemente.Devices of this type are known as screwless clamping devices for connecting conductors from DE 27 06 482 C2. Also known, for example from DE 42 39 480 AI, are spring-loaded terminals with actuating pushers for opening the terminal points. The actuating lever of this spring-loaded terminal moves in the same plane as the pressure springs opened thereby. This proves to be a disadvantage in particular if solar elements designed as roofing or facade elements, as described, for example, in patent application CH 2318/96, are to be installed and electrically connected to one another in series or in parallel. In this case, it is the two conductors with the positive and the negative pole of a solar element that are to be connected to the connections of the solar element directly adjacent to it, for example, laterally. In order to protect the clamping device from the weather, it is expediently attached below the roofing element or the facade element. This requires a special flat design of the clamping device, which is not the case with the clamping device described above. A second disadvantage of these clamping devices is that a separate actuation push button must be operated for each individual conductor. Another disadvantage is that the actuating pushers, for example with a screwdriver, are essentially parallel to the Roof level would have to be operated. All these disadvantages stand in the way of a time-efficient laying of the solar elements designed as roofing elements by a roofer. This also applies accordingly to solar elements designed as facade elements.
Die Aufgabe, die mit der vorliegenden Erfindung gelöst wird, besteht darin, eine Vorrichtung zu schaffen, mit welcher mit einem schnell und einfach auszuführenden Hand- griff ohne spezielle Werkzeuge gleichzeitig zwei oder mehrere elektrische Leiter mit hohen Kontaktdrücken, grossen Auflageflächen und hohen Auszugskräften .dauerhaft, korrosionsbeständig und zuverlässig mit den Anschlüssen von als Bedachungs- oder Fassadenelementen ausgebildeten Solarele- menten verbunden werden können, wobei falsche Verdrahtungen weitgehend ausgeschlossen sind, die Verbindungen in einfache! Weise wieder gelöst und neu erstellt werden können, und der Handgriff von der Oberseite des Solarelements her ausgeführt werden kann.The object that is achieved with the present invention is to provide a device with which two or more electrical conductors with high contact pressures, large contact surfaces and high pull-out forces can be carried out with a quick and easy handle without special tools , corrosion-resistant and reliable with the connections of solar elements designed as roofing or facade elements, whereby incorrect wiring is largely excluded, the connections in simple! Way can be solved again and recreated, and the handle can be carried out from the top of the solar element.

In Fig. 1 ist ein erstes Ausfuhrungsbeispiel der erfin- dungsgemassen Klemmvorrichtung dargestellt. Mit der Ziffer 1 wird ein handelsübliches Bedachungselement, beispielsweise aus Faserzement, bezeichnet. Anstelle von Bedachungselementen sind entsprechende Fassadenelemente immer auch mitgemeint. Ein Solarelement 2 ist mit dem unteren Teil des Bedachungselements 1 fest verbunden, bei- spielsweise auf dieses aufgeklebt. Am Solarelement 2 ist ein flaches, beispielsweise quaderformiges Gehäuse 3 aus Kunststoff angebracht und mit diesem mit bekannten, nicht gezeichneten Mitteln fest verbunden. In einer nicht gezeichneten Variante liegt das Gehäuse 3 fliegend auf dem oberen Teil des Bedachungselements 1 auf. Das Gehäuse 3 enthalt auf zwei beispielsweise entgegengesetzten Seiten e zwe Locher 4, 5. Aus einem Stecker 6 stehen zwei blanke, im wesentlichen parallele Leiter 7, 8 vor, die mit diesem m bekannter Weise fest verbunden sind. Die Leiter 7, 8 sind ihrerseits im Innern des Steckers 6 mit isolierten Anschlussdrahten 9, 10 elektrisch leitend verbunden. In einer nicht gezeichneten Variante sind die Anschlussdrahte 9, 10 direkt durch den Stecker 6 hmdurchge- fuhrt, stehen auf der anderen Seite ohne Isolation etwas vor und bilden so die zwei blanken Leiter 7, 8. Das Gehäuse 3 enthalt aussen an den beschriebenen Seitenflachen vorspringende Ecken 11. Der Stecker 6 weist eine entgegengesetzt passende Ausnehmung 12 auf. Ein weiterer Stekker 13 ist im wesentlichen gleich aufgebaut wie der Stek- ker 6. Das Innere des Gehäuses 3 enthalt vier metallische Stromschienen 14, an welchen m bekannter Weise j e eine Feder 15 angebracht ist. Jede der Federn 15 enthält eine Oeffnung 16 und bildet zusammen mit der entsprechenden Stromschiene 14 je eine Federkraftklemme. Die Stromschienen 14 sind durch Befestigungen 17, 18, 19 fest mit dem Gehäuse 3 verbunden. Zwischen jedem der sich gegenüberstehenden Federpaare 15 befindet sich je ein Exzenterelement, beispielsweise ein ovaler Oeffner 20 aus Kunststoff, der um eine senkrecht zur Zeichenebene stehende Achse um seine Mitte drehbar gelagert ist. Jeder der Oeffner 20 enthält an seiner Oberseite Mittel, mit welchen auf ihn ein durch ein längliches Werkzeug ausgeübtes Drehmoment übertragen werden kann, beispielsweise einen Schlitz 21, in welchen ein gewöhnlicher Schraubenzieher eingreifen kann. Selbstverständlich sind aber auch beliebige andere entsprechende Mittel möglich, beispielsweise Vierkantaus- nehmungen für die Aufnahme eines Vierkantschlüssels oder senkrecht stehende Doppelschlitze für die Aufnahme eines Kreuzschraubenziehers. Die Vorrichtung funktioniert in der folgenden Weise: Der Oeffner 20 wird mittels des länglichen Werkzeugs soweit um seine Achse gedreht, bis dieser in seiner einen Hauptstellung die beiden nebeneinanderliegenden Federn 15 dieser Federkraftklemmen weit öffnet und zur Aufnahme der Leiter 7, 8 vorbereitet, wie dies in der linken Hälfte von Fig. 1 dargestellt ist. Jetzt werden die beiden Leiter 7, 8 des Steckers 6 in die entsprechenden Löcher 4, 5 des Gehäuses 3 eingeschoben. Dabei sind Mittel vorgesehen, die einen falschen Anschluss, insbesondere eine Verwechslung der Pole, verunmöglichen. Diese Mittel bestehen beispielsweise aus einer speziellen Formgebung des Steckers 6 und des Gehäuses 3. In dieser ersten Ausführungsform greift die Ecke 11 des Gehäuses 3 in die Ausnehmung 12 des Steckers 6 ein und verunmöglicht durch diese Formgebung eine falsche Polung der Anschlüsse. Es ist dabei nicht wesentlich, welches von den beiden zusammensteckbaren Teilen die vorstehende Ecke 11 enthält und welches die entgegengesetzt passende Aus- nehmung 12. Wird der Stecker 6 bis zu seinem Anschlag in das Gehäuse 3 eingesteckt, greifen die Leiter 7, 8 in die Oeffnungen 16 der Federn 15 ein. Der Oeffner 20 wird nun erneut um etwa einen rechten Winkel in seine andere Hauptstellung verdreht. Dadurch werden die Federn 15 wieder entspannt und klemmen nun die Leiter 7, 8 mit einer vom Querschnitt dieser Leiter 7, 8 abhangigen Kraft fest, wodurch eine zuverlässige Verbindung zwischen den Leitern 7, 8 und den jeweiligen Stromschienen 14 hergestellt ist, wie dies in der rechten Hälfte von Fig. 1 für den Stecker 13 dargestellt ist. Die Anschlussdrahte 9, 10 enden mit passender Lange in weiteren, nicht gezeichneten Steckern 6, 13, mit welchen die benachbarte Steckverbindung mit den Anschlüssen des nächsten Solarelements 2 realisiert ist. Die Stromschienen 14 sind im Innern des Gehäuses 3 untereinander und mit den Anschlüssen des Solarelements 2 mit nicht eingezeichneten Verbindungen in geeigneter Weise elektrisch verschaltet. Das Gehäuse 3 bietet Platz für weitere übliche Schaltelemente, beispielsweise für ebenfalls nicht eingezeichnete Dioden. Das Gehäuse 3 wird durch einen hier nicht eingezeichneten Deckel 22 aus Kunststoff wasserdicht abgeschlossen.1 shows a first exemplary embodiment of the clamping device according to the invention. The number 1 denotes a commercially available roofing element, for example made of fiber cement. Instead of roofing elements, corresponding facade elements are always also meant. A solar element 2 is firmly connected to the lower part of the roofing element 1, for example glued to it. A flat, for example cuboid-shaped housing 3 made of plastic is attached to the solar element 2 and is firmly connected to it by known means, not shown. In a variant not shown, the housing 3 is floating on the upper part of the roofing element 1. The housing 3 contains two holes 4, 5 on two opposite sides e, for example. From a plug 6 two bare, substantially parallel conductors 7, 8 project, which are firmly connected to this m in a known manner. The conductors 7, 8 are in turn connected in an electrically conductive manner inside the plug 6 with insulated connecting wires 9, 10. In a variant not shown, the connecting wires 9, 10 are passed directly through the plug 6, protrude somewhat on the other side without insulation and thus form the two bare conductors 7, 8. The housing 3 contains projecting on the outside on the side surfaces described Corners 11. The plug 6 has an oppositely fitting recess 12. A further connector 13 is constructed essentially the same as the connector 6. The interior of the housing 3 contains four metallic busbars 14, each of which is known in the m manner Spring 15 is attached. Each of the springs 15 contains an opening 16 and, together with the corresponding busbar 14, forms a spring-loaded terminal. The busbars 14 are firmly connected to the housing 3 by fastenings 17, 18, 19. Between each of the opposing pairs of springs 15 there is an eccentric element, for example an oval opener 20 made of plastic, which is rotatably supported about its center about an axis perpendicular to the plane of the drawing. Each of the openers 20 contains means on its upper side with which a torque exerted by an elongated tool can be transmitted, for example a slot 21, in which an ordinary screwdriver can engage. Of course, however, any other appropriate means are also possible, for example square recesses for receiving a square key or vertical double slots for receiving a Phillips screwdriver. The device works in the following manner: The opener 20 is rotated about its axis by means of the elongated tool until it opens the two adjacent springs 15 of these spring-loaded terminals wide in its one main position and prepares it for receiving the conductors 7, 8, as shown in FIG the left half of Fig. 1 is shown. Now the two conductors 7, 8 of the plug 6 are inserted into the corresponding holes 4, 5 of the housing 3. Means are provided which make incorrect connection, in particular confusing the poles, impossible. These means consist, for example, of a special shape of the plug 6 and the housing 3. In this first embodiment, the corner 11 of the housing 3 engages in the recess 12 of the plug 6 and makes this connection incorrectly polarizing the connections. It is not essential which of the two parts that can be plugged together contains the protruding corner 11 and which the opposite fitting Assumption 12. If the plug 6 is inserted into the housing 3 until it stops, the conductors 7, 8 engage in the openings 16 of the springs 15. The opener 20 is now rotated again about a right angle to its other main position. As a result, the springs 15 are relaxed again and now clamp the conductors 7, 8 with a force dependent on the cross section of these conductors 7, 8, as a result of which a reliable connection is established between the conductors 7, 8 and the respective busbars 14, as shown in FIG right half of Fig. 1 for the connector 13 is shown. The connecting wires 9, 10 end with a suitable length in further plugs 6, 13, not shown, with which the adjacent plug connection with the connections of the next solar element 2 is realized. The busbars 14 are suitably electrically connected to one another in the interior of the housing 3 and to the connections of the solar element 2 with connections not shown. The housing 3 offers space for further conventional switching elements, for example for diodes (also not shown). The housing 3 is sealed watertight by a cover 22 made of plastic, not shown here.

In Fig. 3 ist ein zweites Ausfuhrungsbeispiel der erfin- dungsgemassen Klemmvorrichtung dargestellt. Es entspricht auf seiner linken Seite dem ersten Ausfuhrungsbeispiel. Im Gegensatz zur ersten Ausfuhrungsform enthalt das Gehäuse 3 hier aber nur einen Oeffner 20. Zwei isolierte Anschluss- drahte 25, 26 sind fest mit dem Gehäuse 3 und in seinem Innern fest und elektrisch leitend mit den entsprechenden Stromschienen 14 verbunden. Die Anschlussdrahte 25, 26 enden mit passender Lange m einem weiteren, bereits oben beschriebenen, nicht gezeichneten Stecker 6 respektive 13.3 shows a second exemplary embodiment of the clamping device according to the invention. On its left side, it corresponds to the first exemplary embodiment. In contrast to the first embodiment, the housing 3 contains only one opener 20 here. Two insulated connecting wires 25, 26 are firmly connected to the housing 3 and, in its interior, are firmly and electrically conductively connected to the corresponding busbars 14. The connecting wires 25, 26 end with a suitable length in a further connector 6 or 13, which has already been described above and is not shown.
In Fig. 4 ist ein drittes Ausfuhrungsbeispiel der erfin- dungsgemassen Klemmvorrichtung dargestellt. Das Gehäuse 3 ist auch hier mit dem Solarelement 2 fest verbunden oder liegt, in einer nicht gezeichneten Variante, fliegend auf dem oberen Teil des Bedachungselements 1 auf. Es enthalt mindestens vier Leiter 7, 8, welche mit dem Gehäuse 3 fest verbunden sind. Sie sind untereinander und mit den Anschlüssen des Solarelements 2 im Innern des Gehäuses 3 in geeigneter Weise elektrisch leitend verbunden. Je zwei der Leiter 7, 8 sind auf verschiedenen Seltenwanden des Gehäuses 3 durch dieses hindurchgefuhrt und stehen dort im wesentlichen e senkrecht zu den jeweiligen Seltenwanden vor. Im Gegensatz zu den vorhergehenden Ausführungsformen ist hier die eigentliche Klemmvorrichtung mit Federkraft- klemmen und Exzenterelement nicht im Gehäuse 3, sondern m einer Steckdose 24 aus Kunststoff untergebracht. Die Steckdose 24 enthalt Locher 4, 5 zur Aufnahme der vorstehenden Leiter 7, 8. Die so ausgestaltete Klemmvorrichtung funktioniert im übrigen gleich wie m den bereits früher beschriebenen Ausführungsformen. Die Steckdose 24 ist hier mit einem geöffnetem Oeffner 20 kurz vor dem Zusam- menstecken gezeichnet worden. Eine entsprechende Steckdose 27 ist auf der rechten Seite der Figur 4 in zusammengestecktem Zustand mit geschlossenem Oeffner 20 dargestellt. Ecken 11 und Ausnehmungen 12 dienen auch hier da- zu, einen falschen Anschluss zu verhindern.4 shows a third exemplary embodiment of the clamping device according to the invention. The housing 3 is also firmly connected to the solar element 2 or, in a variant not shown, is floating on the upper part of the roofing element 1. It contains at least four conductors 7, 8, which are firmly connected to the housing 3. They are connected to one another and to the connections of the solar element 2 in the interior of the housing 3 in a suitable, electrically conductive manner. Two of the conductors 7, 8 are passed through the housing 3 on different rare walls and project there essentially e perpendicular to the respective rare walls. In contrast to the previous embodiments, the actual clamping device with spring clips and eccentric element is not housed in the housing 3 but in a socket 24 made of plastic. The socket 24 contains holes 4, 5 for receiving the projecting conductors 7, 8. The clamping device designed in this way otherwise functions the same as in the previously described embodiments. The socket 24 is here with an opened opener 20 shortly before the menu items have been drawn. A corresponding socket 27 is shown on the right side of FIG. 4 in the plugged-together state with the opener 20 closed. Corners 11 and recesses 12 also serve here to prevent incorrect connection.
In Fig. 5 ist ein viertes Ausführungsbeispiel der erfin- dungsgemässen Klemmvorrichtung dargestellt. Es entspricht auf seiner einen Hälfte dem dritten Ausführungsbeispiel. Im Gegensatz zur dritten Ausführungsform enthält das Gehäuse 3 hier aber auf seiner anderen Seite statt der beiden vorstehenden Leiter 7, 8 zwei isoliert weitergehende Anschlussdrähte 25, 26, die hier fest mit dem Gehäuse 3 verbunden und in seinem Innern fest und elektrisch leitend mit den Anschlüssen des Solarelements 2 und den andern beiden Leitern 7, 8 in geeigneter Weise verbunden sind. Die Anschlussdrähte 25, 26 enden mit passender Länge als Anschlussdrähte 9, 10 in einer weiteren bereits oben beschriebenen Steckdose 24 zur Verbindung mit einem benach- barten Solarelement 2.5 shows a fourth exemplary embodiment of the clamping device according to the invention. It corresponds to the third embodiment on one half. In contrast to the third embodiment, the housing 3 here contains on its other side, instead of the two preceding conductors 7, 8, two insulated connecting wires 25, 26, which here are firmly connected to the housing 3 and in their interior are firmly and electrically conductive to the connections of the solar element 2 and the other two conductors 7, 8 are connected in a suitable manner. The connecting wires 25, 26 end with a suitable length as connecting wires 9, 10 in a further socket 24 already described above for connection to an adjacent solar element 2.
In einem weiteren, nicht gezeichneten Ausfuhrungsbeispiel ist das Gehäuse 3 auf einer Seite zur Aufnahme eines Stekkers 5 ausgebildet und enthält genau einen Oeffner 20, wie dies im linken Teil der Fig. 1 dargestellt ist, während es auf der anderen Seite vorstehende Leiter 7, 8 aufweist, die von einer Steckdose 27 aufgenommen werden können, wie dies im rechten Teil von Fig. 4 dargestellt ist. Stromschienen 14 und Leiter 7, 8 sind dabei im Innern des Ge- häuses 3 in geeigneter Weise elektrisch verbunden.In a further exemplary embodiment, not shown, the housing 3 is designed on one side for receiving a plug 5 and contains exactly one opener 20, as shown in the left part of FIG. 1, while it has projecting conductors 7, 8 on the other side has, which can be received by a socket 27, as shown in the right part of FIG. 4. Busbars 14 and conductors 7, 8 are electrically connected in a suitable manner in the interior of the housing 3.
In Fig. 1 und in den Fig. 3 - 5 wurden der Klarheit wegen nur Klemmverbindungen mit jeweils genau zwei gleichzeitig anschliessbaren Anschlussdrähten dargestellt. Ebenfalls erfindungsgemäss ist es, mehrere der hier vorgestellten Vorrichtungen senkrecht zur Zeichenebene übereinander an- zuordnen und im gleichen Gehäuse 3 beziehungsweise in den Steckern 6, 13 oder den Steckdosen 24, 27 zu integrieren, und alle Klemmvorrichtungen durch das gleiche Exzenterelement, beispielsweise durch den gleichen Oeffner 20, betätigen zu lassen, wodurch in einfacher Weise mehr als zwei Anschlussdrähte gleichzeitig angeschlossen werden können. Wie das Gehäuse 3 weisen auch die Steckdosen 24, 27 je einen mit ihnen fest verbundenen, beispielsweise mit ihnen verschweissten, Deckel 22 auf. In Fig. 1 and in Figs. 3-5, for the sake of clarity, only clamp connections with exactly two connecting wires which can be connected at the same time were shown. It is also according to the invention to connect several of the devices presented here one above the other perpendicular to the drawing plane. assign and integrate in the same housing 3 or in the plugs 6, 13 or the sockets 24, 27, and to have all the clamping devices actuated by the same eccentric element, for example by the same opener 20, which means that more than two connecting wires can be operated simultaneously can be connected. Like the housing 3, the sockets 24, 27 each have a cover 22 which is firmly connected to them, for example welded to them.
