20090159749CONNECTOR ELEMENT FOR CONNECTING TWO COMPONENT PARTS - A connector element for connecting two component parts which can be for example a fuselage skin which is connected to a ring frame segment. Alternatively the connector element can also serve as a frame coupling for connecting two ring frame segments. The component parts can be formed with the same materials or with different materials. According to the disclosed embodiments the connector element in the ideal case completely compensates a temperature-conditioned change in length of at least one of the component parts by varying a connector element length of the connector elements. Thus two component parts can be connected together with different materials such as for example a fuselage skin 06-25-2009
