  • One-piece harness and upper shield design and the method of making the same
    Patent number: 6613208
    Abstract: 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.
    Type: Grant

    Date of Patent: September 2, 2003
    Assignee: Delphi Technologies, Inc.

  • Method and apparatus for punch and place inserts for manufacture of oxygen sensor
    Patent number: 6306677
    Abstract: 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.
