ABSTRACT:
A method for manufacturing a gas sensor assembly characterized by including the use of a unitized annular sub-assembly having a plurality of separable terminal portions on it. Pursuant to the invention the terminal portions are pre-formed with holding apertures and electrically and mechanically joined, respectively, to the ends of a plurality of wires that are effective to support and heat elements of the sensor. The heater and support wires are then positioned within a ceramic housing to dispose each of the pre-formed terminals within indexing recesses formed in the housing walls. After the terminals are thus positioned they are individually clamped to the housing, then the annular portion of the terminal sub-assembly is separated from the terminals.
