Abstract

The invention discloses a direct sliding type potentiometer. The direct sliding type potentiometer comprises a shell, a sliding shaft moving in the shell and an outgoing bus installed on the shell, wherein the shell is internally provided with a resistor body assembly; the resistor body assembly comprises an insulation plate provided with a conductor rail and three mounting lines mounted on the insulation plate, and the three mounting lines are converged at the outgoing bus position; one end of the sliding shaft stretches into the interior of the shell, and one end, stretching into the interior of the shell, of the sliding shaft is provided with an electric brush assembly; the electric brush assembly comprises a sliding block fixed on the sliding shaft; a reed is fixed on the sliding block; the reed is connected with the electric brush; and the electric brush is contacted with the conductor rail on the insulation plate. According to the invention, the effective conversion of linear displacement and an electronic signal can be achieved through the direct sliding type potentiometer; and the direct sliding type potentiometer has the advantages of high linearity, long rotating service life, good smoothness and high reliability, and is convenient for use and popularization.

Description

technical field [0001] The invention relates to a potentiometer, in particular to a straight slide potentiometer. Background technique [0002] Potentiometer is a new type of electronic component, which has the characteristics of high rotation life, high linearity index and high reliability index. It is an advanced electronic component that is urgently needed in terms of high reliability, high performance, and long life. It is also a high-precision potentiometer suitable for servo applications that require precise electronic and mechanical output performance. Its output has a linear relationship with the position of the rotating shaft, which can realize the conversion from mechanical motion to electronic signal. The advantages are good smoothness, excellent resolution, good wear resistance, long rotation life, low dynamic noise, high reliability, and chemical corrosion resistance. [0003] With the development of science and technology, the potentiometer has made considera...
