An exhaust gas sensor is provided and formed by attaching the sensor's upper shield and shell. The attachment is attained by bending a protruding segment or lip over a terminal end portion of the lower shield. This produces a single sealing surface and eliminates the requirement of a conventional crimp which places high compressive forces on the sensing element.

One-piece harness and upper shield design and the method of making the same

Disclosed herein is an apparatus and process for punching and placing inserts of electrolyte and other material into a substrate layer for a gas sensor. The insert can be the solid electrolyte, porous electrolyte or protective layer of a gas sensor. The substrate material is typically alumina. The apparatus punches a hole in the alumina substrate, and then, in one step, punches an insert of a second material, such as a solid electrolyte, into the previously formed hole, thereby forming a composite layer/insert.
