Problems solved by technology

The sliding member on the traditional potentiometer is usually fixed on the rotating shaft by using adhesive or fusion riveting. In actual use, when the sliding node member has wrinkles, it will be distorted when the rotating shaft rotates forward and reverse. Creates hysteresis, which prevents accurate angle measurement

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] This solution is aimed at the traditional potentiometer on which the sliding member is usually fixed on the rotating shaft by using adhesive or fusion riveting. In actual use, when the sliding node member has folds, the positive rotation There will be hysteresis when reversing and reversing, and there is a problem that accurate angle measurement cannot be realized. Then, a robust potentiometer is proposed, which can be adjusted accurately and synchronously with the rotation of the shaft, and the entire structure Solid and reliable.

[0018] refer to Figures 1 to 2 As shown, a stability potentiometer 100 in this embodiment includes a housing 1, a resistor body 5 disposed in the inner cavity of the housing 1, a brush assembly 2, and a motor for driving the brush assembly 2. The rotating shaft 6, the brush assembly 2 includes a...

Abstract

The invention provides a stable potentiometer. The stable potentiometer comprises a shell, a resistor body arranged in the inner cavity of the shell, an electric brush piece assembly and a rotating shaft used for driving the electric brush piece assembly to rotate. The brush piece assembly comprises a first rotator, a second rotator and a brush piece component, wherein the brush piece component comprises a flat annular base end part with an insertion opening in the center, a pair of inner side brush pieces and a pair of outer side brush pieces, and the inner side brush pieces and the outer side brush pieces extend from the base end part and are branched into two strands. According to the scheme, the electric brush on the stability potentiometer is installed in the inner cavity of the shellthrough the arranged rotator, when the stability potentiometer works, the rotator is driven by the rotating shaft to synchronously drive the electric brush, the electric brush is installed in the rotator, and therefore the electric brush is driven to synchronously rotate while the rotating shaft rotates, and then accurate precision adjustment is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a robust potentiometer. Background technique [0002] The potentiometer is a kind of variable resistor, which is usually composed of a resistor body and a rotating or sliding system, that is, a movable contact moves on the resistor body to obtain part of the voltage output. The function of the potentiometer is to adjust the voltage and current. size. [0003] When the traditional potentiometer works, when the rotating shaft rotates to a predetermined angle, the sliding contact member composed of brushes and the like arranged on the rotor moves on the resistor, so the resistance value of the resistor changes, and the external voltage value Make changes accordingly. The sliding member on the traditional potentiometer is usually fixed on the rotating shaft by using adhesive or fusion riveting. In actual use, when the sliding node member has wrinkles, it will be distor...
