A flat plate connector including a glass substrate, a conductive silver printing, an adhesion material for electrical connection, an insulated film, a conductive metal strip, and an additional adhesion tape. The flat connector having a dedicated cut-out, where the flat connector before mechanical and electrical bounding with the adhesion material can be fixed with a tape which, depending on its type, can also enhance pull-off resistance and ageing tests. The area is then defined as the surface where the connector adheres to the glass, including the different adhesion materials. The dedicated cut is made in the flat connector to generate a symmetric tensile stress on this adhesion area when the connector is submitted to a pull-off tensile force, the symmetry axis being defined by this pull force axis.
