ABSORBING STRUCTURE FOR GAS SENSOR OF VEHICLE

摘要

The present invention relates to a buffer structure of a gas sensor for a vehicle. The buffer structure of the gas sensor for the vehicle includes: an internal detection part to detect oxygen density in a exhaust gas moving through an exhaust pipe by being inserted into the exhaust pipe; a combining part which is fixed in the exhaust pipe by being installed on an upper part of the internal detection part, and is combined to the exhaust pipe; a tube shape sleeve which is formed on an upper part of the combining part, and comprises an external detection part detecting oxygen density in the atmosphere, and comprises a sensor device inside; a grommet combined with an aperture of an upper part of the sleeve; and a lead wire which transmits oxygen density in the exhaust gas and oxygen density in the atmosphere to an electronic control unit (ECU) of the vehicle by being connected to the sensor device by passing through the grommet. An insulation bush is comprised in the sleeve and is penetrated by the sensor device and has a lower part supported by an upper part of the combining part. A contact bush is comprised in the sleeve, and has a lower part inserted with an upper part of the insulation bush, and comprises a terminal connected to the sensor device inside. And a buffer member is comprised in the sleeve, and buffers impact due to vibration of the vehicle which is delivered to the contact bush.
