Definitions

  • the invention relates to an electrical line connection with a cross-sectional transition region as well as a substrate with a functional element and a composite pane with at least one such line connection.
  • Composite panes which comprise at least two rigid panes and an intermediate layer that connects them flatly, can also have electrical components.
  • the components installed in a composite pane can be heating components, antenna elements and flat-installed functional elements that can be electrically contacted via so-called busbars.
  • Composite windows equipped in this way are used in automobiles as windshields, rear windows and side windows or in the construction sector.
  • the component, for example a functional element is embedded in the composite pane.
  • the functional element is cut out of a multilayer film in the desired size and shape and inserted between the films of the intermediate layer.
  • Typical intermediate layers are polyvinyl butyral films, which, in addition to their adhesive properties, have high toughness and high acoustic attenuation.
  • Such composite disks contain a functional element, which typically comprises an active layer between two surface electrodes.
  • the optical properties of the active layer can be changed by a voltage applied to the surface electrodes.
  • An example of this are electrochromic functional elements.
  • Another example are SPD (Suspended Particle Device) functional elements or PDLC (Polymer Dispersed Liquid Crystal) functional elements.
  • the surface electrodes can be electrically connected to a control module (ECU) via ribbon conductors outside the composite pane.
  • the control module is intended to apply the electrical voltage between the surface electrodes.
  • Such an electrical line connection includes, for example, a cross-sectional transition region as a transition from a ribbon cable to a cable, for example a round cable.
  • the ribbon cables are led out of the interior of the composite pane to serve as an external connection.
  • a ribbon cable consists of at least a thin carrier substrate and a metallic conductor track (conductor strip).
  • a further cover layer is provided so that the ribbon cable forms a three-layer laminate overall.
  • the ribbon cables are included Connection surfaces are soldered close to the edge of the composite pane and only led beyond this edge to the outside, where they are connected with a round cable at a short distance from the edge.
  • the connection point between the two lines is embedded in an encapsulation made of insulating material. Since it is unavoidable that moisture penetrates the encapsulation, faults at the connection point can occur as a result of sealing errors.
  • GB 2 539 834 A describes an electrical connection that electrically connects a flat cable and a cable, the electrical connection comprising a first seal, an optional second seal and a sheath.
  • the casing encloses at least the first seal and the electrical contact. Even with this configuration, it cannot be avoided that disruptions occur at the connection point.
  • the object of the present invention is to provide an improved electrical line connection which ensures a secure and permanently watertight seal at the cross-sectional transition.
  • the invention includes an electrical line connection with a cross-sectional transition area from a ribbon cable to a cable, in particular a round cable.
