Description
Die Erfindung betrifft eine schaltbare Verglasung und ein Verfahren zum Herstellen einer schaltbaren Verglasung.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 to make the transparency of windows in particular changeable. In a known type of switchable glazing, the transparency of an active layer changes by applying a voltage. Such a layer is formed for example by an emulsion, which is introduced between two coated with a conductive layer of plastic films. In order to create an electrical voltage at this, each conductivity layer must be contacted separately. This is currently done by separating the films, removing the emulsion layer, cleaning the possibly scratched conductive layers and brushing the conductive layers with a silver paste. Subsequently, in each case a conductive silver or metal tape is glued to solder on this one cable connection. This procedure may cause the electrical properties of the final products to vary.

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.The object of the present invention is to provide a switchable glazing and a method for producing such, which enable a fast, reliable connection of the conductive layers.
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.This object is achieved by a heating device with the features of claim 1. Advantageous embodiments with expedient developments of the invention are specified in the dependent claims. According to a further aspect of the invention, this object is achieved by a method according to the patent claim 7.
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 present invention eliminates the separation of the films, the removal of the emulsion layer, and the cleaning of the conductive coatings, which may involve a particular amount of work and potentially lead to damage to the conductive coatings, and instead use the capacitive coupling of the conductive coatings to their associated contacts , As a result, the necessary workload is significantly reduced. In addition, soldering is avoided, which is a possible source of error. Preferably, the conductive coatings are contacted capacitively from behind through the plastic films. This creates a reproducible and constant electrical connection.
Gemäß einer bevorzugten Ausgestaltung der Erfindung umfasst die schaltbare Verglasung außerdem zwei Glasscheiben, die mittels Klebefolien mit den transparenten Schichten verbunden sind.According to a preferred embodiment of the invention, the switchable glazing also comprises two glass panes, which are connected by means of adhesive sheets with the transparent layers.
