Abstract: An electrical connection is made by connecting a metal element to a second element to which the electrical connection is desired to be made by means of a conductive material disposed onto one or both of the metal element and the second element so as to contact and disperse about or through the metal element thereby providing both an electrical and a mechanical connection. The metal element may be a strip or pad with openings or knurls formed such as by stamping, a wire that is flattened and knurled, or a mesh material such as a wire mesh. In a preferred embodiment, the conductive material is a metal capable of withstanding harsh, high temperature environments, such as a noble metal. In another preferred embodiment, the second element is a ceramic element, preferably with a noble metal conductive pad thereon, to which the metal element is attached.

Abstract: The gas sensor comprises a sensor element; a shell disposed around at least a portion of the sensor element, the shell having a projecting edge from a first end, wherein a portion of the projecting edge is bent toward the sensing element; an upper shield disposed around at least a portion of the sensor element, the upper shield having a terminal end; a gasket disposed between the projecting edge and the terminal end, wherein the gasket is a U-type gasket; and a lower shield affixed to a second end of the shell.
