Definitions

  • the present invention relates to an electrical connector for glass applications especially relevant in electrical assemblies on the surface of glass. More specifically the present invention relates to an electrical connector used for carrying electrical current to a pane comprising an electrically conductive element comprising a metallic layer or wire. Electrical connector and conductive layer are joined together by a solder material or a conductive adhesive or a glue. Even more the present invention relates specifically to an electrical connector for a pane of a vehicle. Furthermore specifically, the subject-matter of the invention relates to an electrical connector that is useful to transfer electrical energy to an electrical device of a vehicle, such as but not limited to defogger, defroster, heating grid, antenna, camera, sensors and etc.

It is a major problem that connectors with small surfaces like disks or plates fall off after aging test or cannot withhold the required strength. Apart from the soldering material or the adhesive used for the fixing of the connector to the conductive element, shape and size of the connector also has importance on the integrity of the joint. Thus to achieve a strong connection, connectors with relatively high contact areas needs to be used which occupy a significant space for a connection. However, with rapid growth in the demand for vehicle electronics, more and more connections needed for connections to vehicle glazing and the said requirements from the regulations limit manufacturers.
  • connector materials used in the electrical assemblies can be changed to improve the strength of the joint by minimizing thermal and mechanical stresses.
  • Conventional connector material such as copper exhibits superior electrical conductivity, thermal conductivity and low specific heat values, but possess high CTE (16.7 x 10’ 6 /°C) compared to glass which make the joint highly susceptible to stress. Materials with CTE values close to glass have been researched by the manufacturers over the past years.
