Abstract
The utility model discloses a shell of a gas inlet pressure and temperature sensor. The shell comprises a shell body, inserts formed at the front and rear sides of the shell body, a plug-in hole formed in the upper part of the left side of the shell body, a contact pin arranged in the plug-in hole, a platform formed inside the shell body, limiting ribs, cofferdam installation slots, upper cover installation slots, trenches formed in the outer wall of the lower part of the shell body, a pressure detection hole formed in the lower part of the shell body, and a thermistor protection structure used for isolating a thermistor from gas in a gas inlet pipe. By adopting the structure, interference fit can be formed between the shell and a PCB assembly by controlling the size of the four limiting ribs so that the PCB assembly can be effectively fixed on the platform and the work of automatic welding equipment can be facilitated. The thermistor protection structure effectively isolates a thermistor from gas in the gas inlet pipe and avoids corrosion of mixed gas to the thermistor. Therefore, the replacement of a more cost-effective thermistor is made possible.
