Abstract
A gas sensor includes a sensor element, a housing, a hollow porcelain insulator, electrical contacts, a holder, and an air cover. The sensor element is retained inside the housing through the porcelain insulator. The electrical contacts are retained firmly within the porcelain insulator in electrical connection with the sensor element. The air cover is joined to the housing to cover the porcelain insulator. The holder is fit on the porcelain insulator and has stopper springs which are in elastic abutment with an inner shoulder surface of the air cover, thereby stopping the porcelain insulator from moving vertically when the contacts are pulled undesirably through lead wires in order to ensure the stability of electrical connection with the sensor element.
