[0002] Voltage sensor refers to a sensor that can sense the measured voltage and convert it into a usable output signal. In various automatic detection and control systems, it is often necessary to track and collect high-speed changing AC and DC voltage signals, and perform spectrum analysis on more complex voltage waveforms. Voltage sensors are often used to detect voltage fluctuations in computer rooms or between residential floors. Since dust is easily accumulated in computer rooms, it is inconvenient to observe the data of the voltage sensor when dust accumulates on the surface of the voltage sensor. In addition, the wires connected to the voltage sensor are fixed to the surface of the voltage sensor by a fixing component. When the wires are pulled, the wires are easily damaged, resulting in poor contact. Summary of the invention

When the movable plate moves, the extension ring drives the fixing ring to move, and the bent end of the wire is straightened.

[0011] Preferably, the arc rod is elastic, and when the arc rod moves along with the wire, the arc rod is straightened, and the distance between the outer shell and the rubber ball is smaller than the distance between the extension ring and the outer shell.
