Description

Technical Field

[0001] This utility model relates to the field of electrostatic testing technology, and in particular to a vibration capacitive electrostatic sensor structure. Background Technology

[0002] A vibrating capacitive electrostatic sensor is a device used to measure static electricity, typically consisting of a vibrating electrode and a fixed electrode.

[0003] Vibration capacitive electrostatic sensors mainly consist of a vibration device, capacitor plates, signal processing circuits, a housing, and a support device. These components work together to generate an electric field between the electrodes when the object being measured carries static electricity. This changes the capacitance between the electrodes. By detecting the change in capacitance, the amount of static electricity in the object can be determined, thus achieving accurate measurement of static electricity.

[0004] In the existing technology, the vibration capacitive electrostatic sensor has a simple structure, ingenious design, and is relatively convenient to use, and can well meet the measurement needs of electrostatics in various environments. However, it has the drawback that the connection points of each component of the vibration capacitive electrostatic sensor adopt a single connection method and protection method. After long-term use, dust and debris will inevitably enter the internal gaps. Dust and debris pose a great threat to the internal components and may even directly affect the normal operation of the sensor, greatly reducing the safety and stability of the sensor operation. To address this issue, a vibration capacitive electrostatic sensor structure is proposed. Utility Model Content
