Potentiometer with tightness adjusting function

Abstract

The invention relates to the technical field of electronic components, aims to solve the technical problem of inconvenience in adjustment of an output resistance value in an existing potentiometer, and provides a potentiometer with a tightness adjusting function. The potentiometer comprises an insulating bottom plate, a revolving shaft arranged in the center of the insulating bottom plate, half-arc-shaped resistors arranged on the insulating bottom plate around the revolving shaft, an electric brush, and a turning handle connected with the revolving shaft, wherein one end of the turning handle is fixedly connected with the revolving shaft; the revolving shaft is fixedly connected with one end of the electric brush; the moving region of the turning handle on the insulating bottom plate is provided with scale marks; the other end of the electric brush comprises an electric brush base, a connection part and a contact part; the contact part is connected with the electric brush base through the connection part; the half-arc-shaped resistors are embedded into grooves formed by the electric brush base, the connection part and the contact part; the connection part is provided with a fastener; the fastener is used for adjusting the distance between the contact part and the electric brush base; the half-arc-shaped resistors include at least two resistors; and the at least two resistors are connected with each other through a changeover switch. Thus, the potentiometer can be adjusted conveniently.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a potentiometer with tightening adjustment. Background technique [0002] In the prior art, when the potentiometer is controlled by adjusting the brush to control the output amount corresponding to the resistance value, when the brush is adjusted and controlled by the rotating handle, the rotating handle is often in frictional contact with the resistor body, which causes the contact to fail after damage. During the adjustment process of the handle, since the adjustment range cannot be known, it needs to be adjusted back and forth for a long time, and there is a technical problem of inconvenient adjustment. SUMMARY OF THE INVENTION [0003] The embodiment of the present invention solves the technical problem of inconvenient adjustment of the potentiometer in the prior art when adjusting the output resistance value by providing a potentiometer with tightening adjust...
