Abstract
Description
Die Erfindung betrifft einen elektrischen Steckverbinder, insbesondere einen Fotovoltaik- Steckverbinder.The invention relates to an electrical connector, in particular a photovoltaic connector.
Die Erfindung betrifft daher einen Steckverbinder gemÀà dem Oberbegriff von Anspruch 1.The invention therefore relates to a connector according to the preamble of claim 1.
GattungsgemĂ€Ăe Steckverbinder, insbesondere Fotovoltaik-Steckverbinder werden im Bereich fotovoltaischer Anlagen seit geraumer Zeit als bewĂ€hrte Anschlusstechnik eingesetzt.Generic connectors, especially photovoltaic connectors are used in the field of photovoltaic systems for some time as a proven connection technology.
Es handelt sich in der Regel um einpolige Steckverbinder, mit welchen die ElektrizitĂ€t von Solarmodulen abgefĂŒhrt und weitergeleitet werden kann, beziehungsweise mit deren Hilfe Solarmodule miteinander verbunden werden können.These are generally single-pole connectors, with which the electricity of solar modules can be dissipated and forwarded, or with the help of solar modules can be connected together.
Aus SicherheitsgrĂŒnden verfĂŒgen gattungsgemĂ€Ăe Stecker und Buchsen solcher Steckverbinder ĂŒber Rastmittel, die paarweise angeordnete Rastzungen ausbilden, welche mit Gegenrastmitteln des Gegensteckers verbunden werden können.For safety reasons, generic plugs and sockets of such plug connectors have latching means which form latching tongues arranged in pairs and which can be connected to counter-latching means of the mating plug.
Beispielsweise ist aus der
Diese Stecker beziehungsweise Stecker und Buchsen weisen daher Positionierungsmittel auf, um bei der Montage zu gewĂ€hrleisten, dass beim Steckvorgang der Stecker ausschlieĂlich mit in Richtung der Rasttunnel orientierte Rastzungen in die Buche einsetzbar ist.These plugs or plugs and sockets therefore have positioning means to ensure during assembly that during insertion of the plug exclusively with oriented in the direction of the locking tunnel locking tongues can be inserted into the beech.
In zunehmendem MaĂe besteht allerdings das BedĂŒrfnis danach, nicht nur Fotovoltaik-Module sicher miteinander zu verbinden, sondern auch Fotovoltaik-Dachziegel steckbar auszugestalten.Increasingly, however, there is a need not only to securely connect photovoltaic modules with each other, but also to design photovoltaic roof tiles pluggable.
Hierzu wird ein elektrischer Steckverbinder derart benötigt, dass eine Platz sparende Gestaltung die Montage der Ziegel nicht behindert. Insofern ist ein flach bauender elektrischer Steckverbinder notwendig, welcher jedoch ĂŒber ausreichend Isolierstoffdichte verfĂŒgen muss.For this purpose, an electrical connector is needed so that a space-saving design does not hinder the installation of bricks. In this respect, a flat electrical connector is necessary, but which must have sufficient Isolierstoffdichte.
Weitere technische Schwierigkeiten bei einpoligen Steckverbindersystemen besteht in der Regel dadurch, dass die Steckverbinder als typische Rundsteckverbinder relativ groĂe Abmessungen aufweisen.Further technical difficulties in single-pin connector systems is usually the fact that the connectors have a typical circular connector relatively large dimensions.
Es gilt daher, einen Steckverbinder bereitzustellen, der insgesamt flach bauend montierbar ist, jedoch gleichzeitig ĂŒber ausreichende Dichtungseigenschaften verfĂŒgt, so dass der Steckverbinder gegenĂŒber Witterungs- und UmwelteinflĂŒssen abgedichtet ist.It is therefore necessary to provide a connector that is generally flat mounting mountable, but at the same time has sufficient sealing properties, so that the connector is sealed against weather and environmental influences.
Die Abdichtung gegenĂŒber Witterungs- und UmwelteinflĂŒssen muss einerseits im Bereich der Steckgeometrie erfolgen, andererseits aber auch gegenĂŒber dem anschlieĂbaren Fotovoltaik-Kabel.The sealing against weather and environmental influences must be done on the one hand in the field of plug geometry, on the other hand, but also with respect to the connectable photovoltaic cable.
Ein weiterer Anspruch der insbesondere durch Vorgaben der Steckverbindemormung an die Hersteller von Steckverbindersystemen gestellt wird, ist die sichere Verrastung beziehungsweise das sichere Festlegen der Steckverbindung. Es muss also sichergestellt werden, dass der Steckverbinder in seiner gesteckten Position nicht unbeabsichtigt aus dieser gelöst werden kann.Another claim which is made in particular by specifications of the plug-in standardization to the manufacturer of connector systems, the secure locking or secure setting of the connector. It must therefore be ensured that the plug connector in its inserted position can not be inadvertently released from this.
Die fĂŒr Dichtzwecke ideale Materialkombinationen stellen an die Materialauswahl gewisse Anforderungen aber auch Grenzen. So sind fĂŒr die Dichtung vorzugsweise elastische Kunststoffe In einer bevorzugten AusfĂŒhrungsform Gummlwerkstoffe zu verwenden, die zusĂ€tzlich der UV-Belastung und weiteren Umweltbelastungen standhĂ€ltThe material combinations that are ideal for sealing purposes place certain requirements but also limits on the material selection. Thus, for the seal preferably elastic plastics are used in a preferred embodiment rubber materials, which additionally withstands UV exposure and other environmental stresses
Nachteilig bei Gummiwerkstoffen ist jedoch die mangelnde mechanische Festigkeit, um Steckverbinder sicher miteinander zu verrasten.A disadvantage of rubber materials, however, is the lack of mechanical strength to securely lock connectors together.
Aufgabe der vorliegenden Erfindung ist es daher, einen elektrischen Steckverbinder fĂŒr Fotovoltaik-Anwendungen, insbesondere fĂŒr Fotovoltaik-Dachziegel bereitzustellen.The object of the present invention is therefore to provide an electrical connector for photovoltaic applications, in particular for photovoltaic roof tiles.
Weitere Aufgabe der vorliegenden Erfindung ist es dabei, ein Steckverbindersystem derart bereitzustellen, dass ein Teil des Steckverbinders, vorzugsweise die Anschlussdose bereits am Generator, sprich am Fotovoltaik-Dachziegel elektrisch verbindbar ist und die Fotovoltaik-Ziegeln untereinander in elektrischen Kontakt zu bringen sind.Another object of the present invention is to provide a connector system such that a part of the connector, preferably the junction box is already electrically connectable to the generator, that is to say the photovoltaic roof tile and the photovoltaic bricks are to bring into electrical contact with each other.
Das Steckverbindersystem bedarf daher einer technischen Lösung, die es ermöglicht, Dachziegel miteinander zu verschalten. Da jeweils eine Dachziegel mit ihren benachbarten Dachziegeln in elektrischen Kontakt kommen muss, ist es daher je nach Einbau- und Verschaltung notwendig, jeweils drei Ziegeln miteinander elektrisch in steckbarer Verbindung zu bringen.The connector system therefore requires a technical solution that makes it possible to interconnect roof tiles together. Since in each case a roof tile must come into electrical contact with their adjacent roof tiles, it is therefore necessary, depending on the installation and interconnection, to bring each three bricks together electrically pluggable connection.
Aufgabe der vorliegenden Erfindung besteht also auch darin, ein elektrisches Steckverbindersystem derart zu gestalten, dass nicht nur eine Dachziegel mit der nÀchsten verbindbar ist, sondern eine Dachziegel mittels des gleichen elektrischen Steckverbinders mit zwei weiteren Dachziegel in elektrischen Kontakt gebracht werden kann.Object of the present invention is therefore to make an electrical connector system such that not only one tile with the next is connectable, but a tile can be brought by means of the same electrical connector with two other tiles in electrical contact.
Eine weitere Anforderung an ein elektrisches Steckverbindersystem zuvor genannter Art besteht darin, dass die Anschlussdose am Fotovoltaik-Ziegel der Gestalt sein muss, dass diese mit den Kontakten der Generatoreinheit des Ziegels elektrisch kontaktierbar sein muss, möglichst in einfacher und gĂŒnstiger, sprich in einer solchen Weise, dass diese durch MaschinenschweiĂverfahren möglich ist.Another requirement for an electrical connector system of the aforementioned type is that the junction box on the photovoltaic brick must be the shape that it must be electrically contacted with the contacts of the generator unit of the brick, if possible in a simpler and cheaper, ie in such a way in that this is possible by machine welding.
Diese Aufgabe wird mit einem Steckverbinder gemÀà Anspruch 1 gelöst.This object is achieved with a connector according to claim 1.
Weitere bevorzugte AusfĂŒhrungsformen der Erfindung finden sich in den UnteransprĂŒchen.Further preferred embodiments of the invention can be found in the subclaims.
Die Aufgabe der vorliegenden Erfindung wird gelöst mittels eines Fotovoltaik-Steckverbinders, umfassend einer Anschlussdose fĂŒr zwei Buchsensteckverbinder, welche flach bauend so ausgebildet ist, dass die Kontaktelemente der Anschlussdose mittels integrierten Verbindungselementen mit der Generatoreinheit eines Fotovoltaik-Ziegels in einer Direktverbindungstechnik (ohne eine Kabelverbindung) verbindbar sind.The object of the present invention is achieved by means of a photovoltaic connector, comprising a junction box for two female connectors, which is designed to be flat so that the contact elements of the junction box by means of integrated connecting elements with the generator unit of a photovoltaic brick in a direct connection technology (without a cable connection) are connectable.
Diese Aufgabe wird gelöst durch einen Steckverbinder umfassend eine Anschlussdose umfassend einen im wesentlichen flachen Kontaktkörper, wobei der Kontaktkörper Ober zwei Einstecköffnungen mit je einem in den Einstecköffnungen montierten Kontaktelement verfĂŒgt, zum steckbaren Eingriff mit je einem Buchsensteckverbinder.This object is achieved by a connector comprising a junction box comprising a substantially flat contact body, wherein the contact body has two insertion openings, each with a mounted in the insertion contact element for pluggable engagement with a respective female connector.
In einer bevorzugten Ausgestaltung der Erfindung werden die Buchsensteckverbinder zweiteilig ausgefĂŒhrt aus einem buchsenseitigem Kontaktkörper und einem codierten Steckadapter, welcher drehbar am Kontaktkörper festlegbar ist und so codiert ist, dass er nur in eine der beiden Einstecköffnungen der Anschlussdose einschiebbar ist.In a preferred embodiment of the invention, the female connectors are made in two parts of a socket-side contact body and a coded plug-in adapter, which is rotatably fixed to the contact body and is coded so that it can only be inserted into one of the two insertion openings of the junction box.
In einer vorteilhaften Ausgestaltung kann der drehbare Steckadapter zusÀtzlich mit Codierelementen ausgestattet sein, um sicherzustellen, dass der korrekte Kontaktkörper mit dem korrekten Steckadapter verbunden wird, um insgesamt eine korrekte und sichere Steckverbindung mit der Anschlussdose zu gewÀhrleisten.In an advantageous embodiment, the rotatable plug-in adapter can be additionally equipped with coding elements to ensure that the correct contact body is connected to the correct plug-in adapter to ensure a total of a correct and secure plug connection with the junction box.

Stirnseitig am Kontaktkörper 33 der Anschlussdose 2 befinden sich diametral gegenĂŒberliegend jeweils Einstecköffnungen 28a, 28b fĂŒr jeweils einen Buchsensteckverbinder 6. Die Einstecköffnungen 28a, 28b liegen dabei im Bereich der steckseitigen Ausnehmungen 29, welche Teile der Kontur des Buchsensteckverbinders 6 aufnehmen können.The
Die steckseitigen Ausnehmungen 29 bilden insgesamt DurchbrĂŒche im Kontaktkörper 33 der Anschlussdose 2. In einer vorteilhaften Ausgestaltung der Erfindung weist der Kontaktkörper 33 im Bereich der Ausnehmung 29 Codierungen 78, wahlweise in der Anschlussdosenoberseite 20 und/oder in der Anschlussdosenunterseite 27, sowie seitliche FĂŒhrungsmittel 30, vorzugsweise anschlussdosenoberseitige und anschlussdosenunterseitige FĂŒhrungsmittel 30 auf, zum EinfĂŒhren der Buchsensteckverbinder 6 in die Anschlussdose 2.The plug-
Die Anschlussdose 2 verfĂŒgt weiterhin ĂŒber kontakttrĂ€gerseitige Rastmittel 31, vorzugsweise ĂŒber mehrere solcher Rastmittel zum Festlegen und Verrasten mit Gegenrastmittel des Buchsensteckverbinders 6, vorzugsweise mit Rasthaken 73 der Buchsensteckverbinder 6.The
Die kontakttrĂ€gerseitigen Rastmittel 31 werden bevorzugt in DurchbrĂŒchen 32 des KontakttrĂ€gers 2 so im Bereich der steckseitigen Ausnehmungen 29 angeordnet, dass diese in Wirkverbindung mit dem Buchsensteckverbinder beziehungsweise dessen Rastmittel 72 beim Einstecken treten können.The contact carrier-side locking means 31 are preferably arranged in
Wie in
Die Kontakthalteelemente 4 können mit einem elektrischen Verbindungselement 5 zueinander in elektrischen Kontakt gebracht werden, Das Verbindungselement 5 kann dabei ein Stromrichterelement sein, wie beispielsweise eine Diode. Hierdurch kann sichergestellt werden, dass beim Kontaktieren und Verbinden einer Fotovoltaik-Ziegel mit zwei benachbarten Fotovoltaik-Ziegel der Strom und damit der Energietransport nur in eine Richtung erfolgt. Die Kontaktelemente 4 sind metallische Kontaktelemente zum Verbinden mit den Kontakten, vorzugsweise den Stiftkontakten 3 der Steckverbindung.The
Aufgabe der Kontakthalteelemente 4 besteht darin, einerseits eine elektrische Verbindung mit den Kontakten an der Fotovoltaik- Ziegel, sprich den Kontaktpads der Ziegel, herzustellen und andererseits die beiden Stiftkontakte 3 sicher im Kontaktkörper 33 festzulegen. Daher verfĂŒgt das Kontaktelement 4 ĂŒber Halteabschnitte 40 und Befestigungsabschnitten 41. Der Halteabschnift 40 dient der Halterung der Kontaktelemente 3, wĂ€hrend der Befestigungsabschnitt 41 der Befestigung des Kontakthalteelementes 4 am KontakttrĂ€ger 33 dient.The task of the
An den Befestigungsabschnitten 41 befinden sich weiterhin Anschlussenden 42 zur elektrischen Verbindung der Kontakthalteelemente 4 und damit der Kontaktelemente 3 mit der Generatoreinheit des Fotovoltaik-Ziegels beziehungsweise mit den Kontaktfeldem der Fotovoltaik-Ziegel. Diese werden vorzugsweise durch den Kontakt hindurch, somit durch die Nuten 22 hindurch, welche als Ăffnungen im KontakttrĂ€ger 33 ausgebildet sind, mittels Laser an die Kontaktpads der Fotovoltaik-Ziegel elektrisch angeschweiĂt.On the mounting portions 41 are also connection ends 42 for electrically connecting the
Die Halteabschnitte 40 verfĂŒgen weiterhin ĂŒber Rastfedem 43, welche sich an den Rastmitteln 24 beziehungsweise der AnschlagflĂ€che 25 der Rastmittel 24 am Kontaktkörper 33 kraftschlĂŒssig abstĂŒtzen, sobald die Kontakthalteelemente 4 in den KontakttrĂ€ger 33 korrekt eingesetzt sind.The holding
Es ist insofern möglich, ein Kontaktelement 4 entlang der Nut 22 in die Ausnehmung 21 einzusetzen und in Steckrichtung derart zu verschieben, dass die Rastfedern 43 an den Rampen 26 der Rastmittel 24 ausgelenkt werden und nach Erreichen der Montageposition in ihre Ausgangslage zurĂŒckfedern und sich dadurch, wie in
Die Kontaktelemente 3 ragen bei der erfindungsgemĂ€Ăen AusfĂŒhrungsform nicht aus den Einstecköffnungen 28a, 28b heraus, sondern befinden sich vollstĂ€ndig innerhalb dieser, so dass ein BerĂŒhrschutz gegen unbeabsichtiges BerĂŒhren spannungsfĂŒhrender Teile gewĂ€hrleistet ist.In the embodiment according to the invention, the
In den
Der Kontaktkörper 60 ist vorzugsweise aus einem elastischen Kunststoff hergestellt.
In einer bevorzugten AusfĂŒhrungsform wird der Kontaktkörper 60 aus UV bestĂ€ndigem Gummi hergestellt.The contact body 60 is preferably made of an elastic plastic.
In a preferred embodiment, the contact body 60 is made of UV resistant rubber.
Der Steckadapter 61 ist aus einem, gegenĂŒber dem elastischen Kunststoff, festeren, nahezu massiven Kunststoff erzeugt. Dies dient dazu, dass die StabilitĂ€t des Steckverbinders und damit die Haltefunktion durch den weniger elastischen Steckadapter 61 erzeugt wird, wĂ€hrend die Dichtfunktion, also die dichtenden Eigenschaften gegen Umwelt- und FeuchtigkeitseinflĂŒsse durch den elastischen Gummikontaktkörper 60 erzeugt werden.The plug-in
Der Kontaktkörper 60 verfĂŒgt dabei ĂŒber einen zylinderförmigen Buchsenkontakthalter 62, in welchem ein zylinderförmiger Buchsenkontakt 75 eingebracht ist. Der Buchsenkontakt 75 ist verbindbar mit einer Leitung 76. Der Durchmesser der Leitung 76 ist dabei abzustimmen auf die Ăffnung der KabeltĂŒlle 68, welche sich am Kontaktkörper 60 befindet. Die KabeltĂŒlle 68 umschlieĂt dabei dichtend das Kabel 76. Auf der gegenĂŒberliegenden (steckseitigen) Seite des Kontaktkörpers 60 befindet sich zwischen dem zylinderförmigen Buchsenkontakthalter 62 und dem eigentlichen Kontaktkörper 60 ein Adapterverbindeabschnitt 65, geeignet zum Verbinden mit dem Steckadapter 61.The contact body 60 has a cylindrical
Der Adapterverbindeabschnitt 65 umfasst dabei Codierelemente 66 in vorteilhafter Weise als seitlich angebrachte stegartige Rastelemente zum Eingriff in die Anschlussdose 2. Mittels der Codierelemente 79, welche vorteilhaft als Stufe am Steckadapter 61 ausgebildet ist, sichergestellt, dass nur der jeweilig korrekte Steckadapter 61 mit der jeweilig korrekten Einstecköffnung 28a, 28b verbunden ist.The
In einer vorteilhaften AusfĂŒhrungsform der Erfindung kann darĂŒber hinaus eine Farbcodierung eines der beiden GegenstĂŒcke, sprich der Steckadapter 61 oder der Kontaktkörper 60 angebracht sein. Zur Montage des Kontaktkörpers 60 fĂŒhrt man diesen mit dem zylinderförmigen Buchsenkontakthalter 62 durch die buchsenkontakthalterseitige DurchfĂŒhrung 74 bis der Adapterverbindeabschnitt 65 am Steckeradapter 61 anliegt und Eingriffsmittel 70 des Steckadapters 61 durch Drehen am Steckadapter 61 mit einer Eingriffsnut 69 des Kontaktkörpers 60 im Bereich des Adapterverbindeabschnitts 65 festgelegt werden kann. Dabei lĂ€sst sich, wie bereits zuvor erlĂ€utert, der Steckadapter 61 nur in die gewĂŒnschte Dreh/-Rastposition einbringen, wenn die Gegencodiermittel 67 mit den Codiermitteln 66 des Kontaktkörpers 60 zueinander passen.In an advantageous embodiment of the invention, a color coding of one of the two counterparts, that is to say the plug-in
Der Steckadapter 61 kann dabei in vorteilhafter Weise ĂŒber einen zylindrischen Anpressabschnitt 80 verfĂŒgen, der in seiner Abmessung so ausgebildet ist, dass der zylinderförmige Buchsenkontakthalter 62 im montierten Zustand eine Pressung durch diesen erfĂ€hrt,The plug-in
Wie weiterhin in den
Sobald der Buchsensteckverbinder 6 in die Anschlussdose 2 vollstĂ€ndig eingefĂŒhrt ist, lĂ€sst sich dieser bestimmungsgemÀà nur mittels eines Lösewerkzeugs 77 aus seiner Steckposition lösen, um ihn von der Steckverbindung zu trennen. Das Lösewerkzeug 77 kann dabei in die DurchbrĂŒche 32 des Kontaktkörpers 33 derart eingreifen, dass die kontakttrĂ€gerseitigen Rastmittel 31 ausgefedert werden und dabei die Rastmittel 72 des Steckadapters 61 freigeben.Once the
