Abstract
Description
Die Erfindung betrifft eine schaltbare Verglasung und ein Verfahren zum Herstellen einer schaltbaren Verglasung.The The invention relates to a switchable glazing and a method for producing a switchable glazing.
Schaltbare Verglasungen sollen dazu dienen, die Transparenz insbesondere von Fensterscheiben veränderbar zu machen. Bei einem bekannten Typ von schaltbaren Verglasungen ändert sich die Transparenz einer aktiven Schicht durch Anlegen einer Spannung. Eine solche Schicht wird beispielsweise durch eine Emulsion gebildet, die zwischen zwei mit einer Leitfähigkeitsschicht beschichtete Kunststofffolien eingebracht wird. Um an dieser eine elektrische Spannung anlegen zu können, muss jede Leitfähigkeitsschicht getrennt kontaktiert werden. Dies geschieht derzeit durch Trennen der Folien, Entfernen der Emulsionsschicht, Reinigen der eventuell verkratzten Leitfähigkeitsschichten und Bestreichen der Leitfähigkeitsschichten mit einer Silberpaste. Anschließend wird noch jeweils ein leitfähiges Silber- oder Metallband aufgeklebt, um auf diesem einen Kabelanschluss zu löten. Dieses Verfahren kann dazu führen, dass die elektrischen Eigenschaften der Endprodukte variieren.switchable Glazing should serve the transparency, in particular of To make window panes changeable. In a known Type of switchable glazing changes the transparency an active layer by applying a voltage. Such Layer is formed for example by an emulsion between two plastic films coated with a conductive layer is introduced. To create an electrical voltage at this To be able to, each conductivity layer must be separated be contacted. This is currently done by separating the slides, Removing the emulsion layer, cleaning the possibly scratched Conductive layers and coating of the conductive layers with a silver paste. Subsequently, one more each conductive silver or metal tape glued on to to solder this one cable connection. This method can cause the electrical properties of the final products vary.

diesem Zusammenhang sei außerdem auf die
Aufgabe der vorliegenden Erfindung ist es, eine schaltbare Verglasung und ein Verfahren zum Herstellen einer solchen zu schaffen, welche eine schnelle, prozesssichere Kontaktierung der leitfähigen Schichten ermöglichen.task The present invention is a switchable glazing and to provide a method of making such a fast, Reliable contacting of the conductive layers enable.
Diese Aufgabe wird erfindungsgemäß durch eine Heizvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. Gemäß einem weiteren Aspekt der Erfindung wird diese Aufgabe durch ein Verfahren gemäß dem Patentanspruch 7 gelöst.These The object is achieved by a heater solved with the features of claim 1. advantageous Embodiments with expedient developments The invention are defined in the dependent claims specified. According to another aspect of the invention This object is achieved by a method according to the Claim 7 solved.
Die vorliegende Erfindung verzichtet auf das Trennen der Folien, das Entfernen der Emulsionsschicht und das Reinigen der leitfähigen Beschichtungen, welche einen besonderen Arbeitsaufwand bedeuten und unter Umständen zu einer Beschädigung der leitfähigen Beschichtungen führen können und verwendet stattdessen die kapazitive Kopplung der leitfähigen Beschichtungen mit deren zugehörigen Kontakten. Dadurch wird der nötige Arbeitsaufwand erheblich reduziert. Außerdem wird ein Löten vermieden, das eine mögliche Fehlerquelle darstellt. Vorzugsweise werden die leitfähigen Beschichtungen von hinten durch die Kunststofffolien hindurch kapazitiv kontaktiert. Dadurch wird eine reproduzierbare und konstante elektrische Verbindung geschaffen.The The present invention dispenses with the separation of the films, the Remove the emulsion layer and clean the conductive Coatings, which mean a special workload and possibly damage the can lead to conductive coatings and instead uses the capacitive coupling of the conductive Coatings with their associated contacts. Thereby the necessary amount of work is considerably reduced. Furthermore soldering is avoided, which is a possible source of error represents. Preferably, the conductive coatings become capacitively contacted from behind through the plastic films. This results in a reproducible and constant electrical connection created.
Gemäß einer bevorzugten Ausgestaltung der Erfindung umfasst die schaltbare Verglasung außerdem zwei Glasscheiben, die mittels Klebefolien mit den transparenten Schichten verbunden sind.According to one preferred embodiment of the invention comprises the switchable glazing In addition, two glass panes, which by means of adhesive sheets with connected to the transparent layers.
