转轴式电位器

Rotating shaft type potentiometer

Abstract

The utility model discloses a rotating shaft type potentiometer, which comprises a rotating shaft and a front shell, wherein the rotating shaft is installed on the front shell; a magnet that can interlock with the rotating shaft is arranged at the rear end of the rotating shaft; a chip board that corresponds to the magnet and converts magnetic flux to voltage signals is arranged on the rear side of the rotating shaft; a disc component is arranged at the rear part of the rotating shaft; the disc component can limit the forward movement of the rotating shaft on the front shell; in addition, an obstructing component is arranged between the magnet and the chip board; and magnetic lines of the magnet can penetrate through the obstructing component. Through the adoption of a non-contact structure, the service life is prolonged greatly; and the disc component is adopted to limit the rotating shaft to move forward, and the obstructing component is adopted to limit the rotating shaft to move backward, so that the reliability of the rotating shaft is improved, and the stability of measured data is improved.
本实用新型公开了一种转轴式电位器,包括转轴和前壳,所述转轴安装在所述前壳上,在所述转轴后端装有能够随该转轴连动的磁铁,所述转轴后侧设有与所述磁铁对应的将磁通量转换为电压信号的芯片板,所述转轴后部设有盘件,该盘件能够限制所述转轴在所述前壳上向前移动,在所述磁铁和芯片板之间设有阻挡件,所述磁铁的磁力线能够穿过所述阻挡件。采用非接触式结构,使用寿命大大增加,采用盘件限制转轴向前移动,采用阻挡件限制转轴向后移动,增加了转轴的可靠性,提高了测量数据的稳定性。
