Problems solved by technology

[0002] The potentiometer is a commonly used electronic component, which is widely used in the adjustment switches of various electrical equipment. At present, the traditional potentiometer adjusts the potential through the rotation of the adjustment rod. There is a certain amount of friction between the side walls of the shell, and it is often easy to loosen and leak dust over time, resulting in unstable performance of the potentiometer

Abstract

The invention discloses a sleeve rod potentiometer. The sleeve rod potentiometer comprises a protective shell, a potential adjusting ring, an insulating base, an adjusting rod and an electric brush, wherein the potential adjusting ring is arranged on the insulating base through a rotary shaft arranged at the center of the insulating base; the potential adjusting ring comprises a resistor body and an adjusting ring; one end of the electric brush is pressed on the resistor body and the other end of the electric brush is fixedly arranged on the insulating base; the adjusting rod penetrates into the protective shell from the side face of the protective shell; the adjusting rod is composed of a sleeve rod and an inner rod; the sleeve rod is sleeved with the outer side of the inner rod and the outer side of the sleeve rod is fixedly connected with the side wall of the protective shell; an adjusting screw cap is arranged at the top of one end of the inner rod outside the protective shell; an adjusting wheel is arranged at the top of one end inside the protective shell and is pressed on the adjusting ring. According to the sleeve rod potentiometer, ash is prevented from entering a leaking gap of the protective shell effectively and the adjustment is stable.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a rod potentiometer. Background technique [0002] The potentiometer is a commonly used electronic component, which is widely used in the adjustment switches of various electrical equipment. At present, the traditional potentiometer adjusts the potential through the rotation of the adjustment rod. However, the rotation of the adjustment rod will always be related to the protection There is a certain amount of friction between the side walls of the shell, and it is often easy to loosen and leak dust over time, resulting in unstable performance of the potentiometer. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a rod potentiometer, which can effectively prevent the friction between the adjusting rod and the side wall of the protective shell when the adjusting rod is rotated. [0004] The techni...
