Problems solved by technology

[0003] Existing wire-wound potentiometers manually move the clamp when adjusting the resistance, but manual direct movement of the clamp is likely to cause uncontrollable force, which makes the adjusted resistance change in a large range. For some compact instruments, if the resistance of the potentiometer is not adjusted Stable, easy to cause instrument damage

Abstract

The invention discloses an adjustable potentiometer, which includes a support base, and there are two support bases. The adjacent sides of the support bases are fixedly connected with support blocks. A connecting core is fixedly installed between them, the wall of the connecting core is wound with a resistance wire, and a screw rod is installed between the adjacent sides of the support seat, and the screw rod is threadedly connected with a moving block, and the moving block of the moving block An identification plate is fixedly installed on the top, clips are connected by bolts on both sides of the moving block, and a first contact bolt is fixedly installed on the other side of one of the support bases, and one end of the first contact bolt is connected with a first contact bolt. A locking cap, the other side of the support base is fixedly installed with a second contact bolt, one end of the second contact bolt is connected with a second locking cap, and the axis position of the second contact bolt is provided with a through hole. This design has reasonable structure, simple operation, and more accurate and stable adjustment of resistance.

Description

technical field [0001] The invention relates to the technical field of potentiometers, in particular to an adjustable potentiometer. Background technique [0002] A potentiometer is a type of variable resistor. It 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. This article is about a wire wound potentiometer. Wire-wound potentiometers have the advantages of high precision, good stability, small temperature coefficient, reliable contact, high temperature resistance, and strong power load capacity. This type of potentiometer is widely used in electronic instruments and meters. The resistor body of the wire wound potentiometer is composed of resistance wire wound on the insulator. There are many types of resistance wire. The material of the resistance wire is selected according to the structure of the potentiometer, the space for containing the resistance wire...
