Abstract
A pressure sensor device includes a pressure sensor, a sensor case, first and second terminals protruding from the pressure sensor in a first direction, a third terminal protruding from the pressure sensor in a second direction, a fourth terminal protruding from the pressure sensor in the second direction, a first capacitor on one side of the pressure sensor, a second capacitor on the other side of the pressure sensor, a first lead line extending out of the sensor case from the first terminal, a second lead line extending out of the sensor case from the second terminal, and a third lead line extending out of the sensor case from a side edge between the first terminal and the second terminal.
Claims12
A pressure sensor device for an electric pump, the pressure sensor device comprising:
- a pressure sensor to measure a pressure of fluid inside the electric pump;
- a sensor case housing the pressure sensor;
- a first terminal and a second terminal protruding from the pressure sensor in a first direction extending toward a first side in a horizontal direction;
- a third terminal protruding from the pressure sensor in a second direction extending toward a second side in the horizontal direction;
- a fourth terminal protruding from the pressure sensor in the second direction and electrically connected with the second terminal;
- a first capacitor disposed on the first side of the pressure sensor in the horizontal direction and connecting the first terminal and the second terminal;
- a second capacitor disposed on the second side of the pressure sensor in the horizontal direction and connecting the third terminal and the fourth terminal;
- a first lead line electrically connected with the first terminal and extending out of the sensor case from the first terminal toward the first side in the horizontal direction;
- a second lead line electrically connected with the second terminal and extending out of the sensor case from the second terminal toward the first side in the horizontal direction;
- a third lead line electrically connected with the third terminal and extending out of the sensor case from a side edge between the first terminal and the second terminal toward the first side in the horizontal direction;
- and
- a guide that guides the third lead line from the second side of the pressure sensor in the horizontal direction to the first side of the pressure sensor in the horizontal direction;
- wherein
- the guide is disposed inside the sensor case;
- and
- the third lead line is guided to the first side of the pressure sensor in the horizontal direction through an inside of the sensor case by the guide.
