The invention discloses a wide-band
oxygen sensor structure. The wide-band
oxygen sensor structure comprises a
chip, a shell, a short protective cover and a
signal conductor, wherein the
chip comprises a mainboard, an induction sheet and a
contact electrode; a locating seat used for fixing the
chip to prevent the chip from shaking in the shell during operation is arranged between the shell and thechip, and all parts, except the induction sheet, of the chip are arranged in the locating seat; and the
signal conductor and the chip are connected through an elastic sheet connector, and the elasticsheet connector is inserted into the
tail of the locating seat to make contact with the
contact electrode and make a
signal conducted. The wide-band
oxygen sensor has the advantages that talcum
powder production rings are arranged between the shell and the chip, the rings are crushed and filled into surrounding space, and then a sealing function can be achieved; and since the signal conductor andthe chip are connected through the elastic sheet connector, the assembling and debugging efficiency of the
oxygen sensor in an assembling technological process is improved by changing an existing
welding mode into an elastic
sheet structure inserting / pulling connection mode.
