Abstract

The invention discloses an angle potentiometer, which comprises a cover body, a seat body and a rotating shaft, the cover body and the seat body are assembled and buckled, the rotating shaft penetrates through the seat body and can rotate around a vertical shaft, a vertical resistor disc is arranged on the inner circumferential side of the cover body, and a brush body in elastic contact with the resistor disc is arranged on the outer circumferential side of the rotating shaft. According to the angle potentiometer, the resistor discs are vertically arranged to prevent powder accumulation afterthe resistor discs are abraded, the problems that the abraded resistor discs influence the service life and redundant materials are accumulated to influence the performance due to abrasion of the powder are solved, and the angle potentiometer has the characteristics of long service life and good performance.

Description

technical field [0001] The invention relates to the technical field of adjustable resistors, in particular to an angle potentiometer. Background technique [0002] Angle potentiometer (angular displacement conductive plastic potentiometer) is a detection element that converts rotation angle position information or linear position information into electrical signals through contact. Its reliability, resolution, accuracy, environmental adaptability and other characteristics are directly related. Affects the servo performance of the entire servo system. [0003] The current angular displacement conductive plastic potentiometers widely use brushes made of alloys, relying on the deformation of the brush itself to generate a certain pre-tightening force close to the resistor area, and the corresponding electrical signals generated by the brush passing through the resistor area correspond to different Angle. However, this kind of position sensor that relies on the pre-tightening ...
