发明名称 CHARACTERISTIC ADJUSTING MEANS FOR PHYSICAL QUANTITY DETECTING DEVICE AND HEATING RESISTOR TYPE AIR FLOWMETER
摘要 <p>PROBLEM TO BE SOLVED: To provide a physical quantity detecting device which can detect the physical quantity of an object with high accuracy by providing a terminal for adjusting output characteristic of the detecting device or terminal for adjusting controlled variable of a detecting element on the outside of a housing incorporating an electronic circuit. SOLUTION: An electronic circuit 4 is stuck and fixed to a metallic base 6 and surrounded by a housing 5. The housing 5 is plastic parts on which connector terminals 2, adjusting terminals 1, and detecting element terminals 9 are insert-molded and a connector housing 3, a fixing flange 10, etc., are integrally formed with the housing 5. Therefore, the electronic circuit 4 is incorporated in a box-like body having a bottom face composed of the metallic base 6 and side walls composed of the housing 5 and terminals 1 are electrically connected to the terminals 2 when the inside of the housing 5 is connected to the circuit 4 through metallic wires 8. When electric signals are impressed upon the terminals 1 in the connector housing 3 after the construction of a physical quantity detecting device is completed, the characteristics of the device can be adjusted in the final process.</p>
