    摘要： A lead wire for a sensor has a conductor unit including at least stainless steel wires and copper wires. By setting the cross-sectional percentage of the stainless steel wires in the conductor unit within the range of 30 to 70%, it is possible to obtain a lead wire having low electrical resistance, and high flexibility, tensile strength and elasticity. There are preferred values in hardness and heat treatment of the stainless steel wires. The copper wires are preferably coated with an antioxidant film. The lead wire may include hybrid wires stranded together and obtained by integrally molding or forming stainless steel and copper. It is preferable that the lead wire is coated with an insulating coating material such as a Teflon type resin.

    摘要： An air-fuel ratio sensor comprises an oxygen concentration sensing element, a housing for holding this oxygen concentration sensing element, and protecting covers with gas holes. The protecting covers comprises an inside cover disposed closely to the oxygen concentration sensing element, and an outside cover surrounding the outside cover. Flange-like peripheral portions, formed on the protecting covers, are fixed to the abutting face of the housing by a caulking operation. These flange-like peripheral portions are disposed alternately along a same closed curve around the oxygen concentration sensing element, so that they are not overlapped with each other.

    摘要： A gas sensor includes a sensor element having one end portion exposed to gas to be measured. A plurality of electrodes are provided on the other end portion of the sensor element. A plurality of terminal contacts are resiliently held in electrical contact with the electrodes, respectively, in such a manner that the terminal contacts hold the other end portion of the sensor element therebetween. The electrodes are so provided on the sensor element that the terminal contacts abut against the electrodes to prevent the sensor element from being moved axially and laterally.

    摘要： A small-sized highly accurate gas sensor, which is excellent in its reliability of electric connections between contacts and fixtures while being freed from any damage, includes a base member; a detecting unit mounted on the base member for detecting a gas concentration; electrodes mounted on the detecting unit; cylindrical contacts buried integrally in an end portion of the base member; and electric leads interposed between the cylindrical contacts and the electrodes. Contacting fixtures for external lead wires are fitted in and contact the cylindrical contacts so that they are connected to the cylindrical contacts. The cylindrical contacts are formed in their openings with engaging entrances having a smaller diameter than the internal diameter, and the contacting fixtures include elastic contacting portions adapted to be diametrically reduced, when inserted into the cylindrical contacts, than the engaging entrances and expanded, after inserted, to become larger than the engaging entrances and to contact the inner walls of the cylindrical contacts.
