Abstract
The utility model discloses a capacitive sensor, and a capacitor serves as a carrier. The capacitive sensor comprises a pedestal, a rubber gasket, a copper sheet 1, a copper sheet 2, a copper sheet 3, and a locking screw. The copper sheet 3 of a pressure-sensing part is provided with an elastic deformation part and a fixed part in the axial direction. When a force is applied to the copper sheet 3, the copper sheet 3 can deform correspondingly, thereby pushing the copper sheet 2 to move, changing the distance between the copper sheet 2 and the copper sheet 1, and changing the capacitance value of the capacitor. Through the above design, the sensor employs fewer parts, is simpler in assembly process, is high in efficiency of production, is low in cost of manufacture, and is more accurate.
