Definitions

  • the invention relates to a connection arrangement with a flat conductor connection element and an electrical line connection.
  • Such line connections usually include a transition from a flat conductor connection element to a round cable.
  • the electrical components installed in a composite pane can be heating components, antenna elements and flatly installed functional elements that can be electrically contacted via so-called bus conductors.
  • Composite panes equipped in this way are used as glazing units in automobiles as windshields, rear windows and side windows or in the construction sector.
  • the functional element is embedded in the composite pane.
  • the functional element is cut to the desired size and shape and inserted between 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.
  • the intermediate layer prevents the composite pane from disintegrating if damaged.
  • the composite pane only gets cracks, but remains dimensionally stable.
  • Such composite panes as glazing elements contain the 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.
  • electrochromic functional elements which are known, for example, from US 20120026573 A1.
  • SPD functional elements Small Particle Device
  • PDLC functional elements Polymer Dispersed Liquid Crystal
  • flat cables which consist of at least one thin carrier substrate and at least one metallic conductor track (conductor strip).
  • a cover layer can be provided so that the Flat conductor forms a three-layer laminate overall.
  • the flat conductors are soldered to connection surfaces close to the edge of the composite disk and are only led out over this edge, where they are connected to a round cable at a distance from the edge.
  • the electrical conductor tracks are very thin with thicknesses, for example, in the range of 0.03 mm to 0.1 mm and are made, for example, of copper, which has proven itself because it has good electrical conductivity and good processability. At the same time, the material costs are relatively low.
  • Such flat conductor connection elements have a first connection area for contacting an electrical component, for example a functional element, within the composite pane. At the other end, the flat conductor connection element is led out of the composite disk. Since it is unavoidable that moisture penetrates into the composite pane along the flat cable, problems can occur at the contact point as a result of sealing errors.
  • a second connection area is located at the end of the flat conductor connection element that leads out of the composite disk. The second connection area is intended for contacting with a connection cable (round cable).
  • the connection cable typically has pre-assembled connectors such as plugs or sockets on one side, with which the round cable can be connected to external electrical devices.
  • the transition area from the flat conductor connection element to the round cable is sensitive to dust, dirt and moisture and is therefore embedded in a plastic jacket, housing or encapsulation. Since it is unavoidable that moisture penetrates into the encapsulation, faults at the connection point can also occur here as a result of sealing errors.
  • JP 2003257597 A discloses a flat heating element arranged via a conductive tape on an end part of a wire connected to a power supply.
  • 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.
