Pressure and temperature sensor assembly for internal combustion engines

A pressure and temperature sensor assembly for internal combustion engines, comprising

• a pressure sensor member having a pressure inlet pipe on a bottom center thereof,
• a circuit board electrically connected to said sensor member,
• a housing receiving both the sensor member and the circuit board therein and being formed by integrating a top case and a bottom case into a single structure, said top case being integrated with a connector including a plurality of connection terminals, and said bottom case being provided with a pressure inlet port being concentric with the pressure inlet pipe of the sensor member, wherein
• said bottom case is partially protruded downward at a portion around said pressure inlet port, thus including a temperature sensing rod extending downwardly from a lower edge of said pressure inlet port to a predetermined length, with a temperature sensor chip being interiorly installed in said temperature sensing rod and being electrically connected to said connection terminals of the connector;
• wherein said temperature sensor chip is electrically connected to said connection terminals of the connector by electric connection means, said electric connection means comprising:
• a temperature sensing pin terminal mounted to a lower surface of said top case and electrically connected to said connection terminals of the connector;
• and
• a side connection terminal extending from a top side of said bottom case to a predetermined length, said side connection terminal being connected to the temperature sensor chip and being brought into contact with said temperature sensing pin terminal, thus electrically connecting the temperature sensor chip to the connection terminals of the connector through the temperature sensing pin terminal.
