Embodiment Construction

[0103] figure 1 with figure 2 The details of one configuration of the composite sheet according to the invention with electrical contacts are shown in each case. The transparent composite sheet comprises a first sheet 1 and a second sheet 2 which are connected to each other via a thermoplastic interlayer 4 . The composite sheet is a windshield of a passenger car, wherein the first sheet is arranged to face the interior in the installed position. The first sheet 1 and the second sheet 2 consist of soda lime glass. The thickness of the first sheet 1 is 1.6 mm, and the thickness of the second sheet 2 is 2.1 mm. The thermoplastic intermediate layer 4 consists of polyvinyl butyral (PVB) and has a thickness of 0.76 mm. On the inner side surface (I) of the first sheet 1 is applied a conductive coating 3 . The electrically conductive coating 3 is a layer system comprising, for example, three electrically conductive silver layers which are separated from one another by a dielectr...

Abstract

The present invention relates to a composite pane with electrical contact-making means, at least comprising: - a first pane (1) and a second pane (2), which panes are connected to one another over their surface by means of a thermoplastic intermediate layer (4), - at least one electrically conductive coating (3) at least on the inner surface (I) of the first pane (1), - at least one busbar (5) on a region of the electrically conductive coating (3), and - at least one electrically conductive contact strip (6) on at least one region of the busbar (5), wherein the contact strip (6) is connected to at least one electrical feed line (7), and at least one region of the contact strip (6) is in direct contact with the busbar (5).

Description

technical field [0001] The invention relates to a composite sheet with electrical contacts, a method for producing the composite sheet and its use. Background technique [0002] Composite sheets are known which have an electrically conductive coating on the inside surface of one of the individual sheets, which is electrically contacted, ie connected, for example, to an external voltage source or to a receiving device. Such electrically conductive coatings are, for example, metal-based heatable coatings. Other known electrically conductive coatings are, for example, electrically switchable functional elements such as electrochromic functional elements or surface electrodes of thin-film photovoltaic modules. The electrical contacting of the conductive coating is typically made via bus conductors, for example made of embossed and baked silver paste. The bus conductor can be electrically conductively connected to an external lead, for example a flat conductor, directly or also...
