HEATER COIL FOR GAS SENSOR, DETECTION ELEMENT FOR GAS SENSOR, CONTACT COMBUSTION TYPE GAS SENSOR, AND METHOD FOR MANUFACTURING CONTACT COMBUSTION TYPE GAS SENSOR

摘要

1 of the present invention is wound around the lead portion 25 of the heater coil (2) , a coil-shaped constituted by a winding coil , and the bead portion 24, the first coil of the second winding is configured by winding a coil winding into the coil shape of the back . Embedding the bead portion 24, the heat conductive layer 21, and by attaching a catalyst layer 23 on the surface of the heat conductive layer 21 , by a detector element (2) , the sensitivity and the response speed of the gas contact combustion type gas sensor the improved . In addition , by improving the impact strength is decreased to zero point fluctuations . A platinum wire , etc. When fixed to each end of the heater coil to the electrode pin as the first state wound on the core wire , and both ends of the heater coil to the electrode pin , welded by resistance welding method or the like , subjected to a wet etch process , such as a platinum wire left , holding a primary core melt line extinguishes .
