Abstract
The invention discloses an anti-static potentiometer. The anti-static potentiometer comprises a shell. The shell comprises a lower shell and an upper shell. An anti-static coating is arranged on the outer surface of the shell. A shaft sleeve is arranged at the top of the upper shell. A cavity is formed between the lower shell and the upper shell. A rotation shaft, a conductive rotation slice, a first fixing pin slice, a second fixing pin slice, a moving pin slice and a circular-arc resistor body are arranged in the cavity. The rotation shaft matches with the shaft sleeve. The rotation shaft comprises a metal inner core and a graphite outer layer. The first fixing pin slice and the second fixing pin slice are connected at two ends of the circular-arc resistor body. Through adoption of the mode, according to the potentiometer provided by the invention, accumulation and generation of static electricity can be effectively prevented on the surface; and the damage of the static effect to the potentiometer can be eliminated.
Description
Technical field
The present invention relates to potentiometer field, particularly relate to a kind of antistatic potentiometer.
Background technology
Potentiometer be there are three exits, resistive element that resistance can be regulated by certain Changing Pattern, potentiometer is generally made up of resistive element and moveable brush.Potentiometer is installed in enterprising enforcement of various equipment and uses; play regulation effect; existing rotational potentiometer lubricity is poor; fretting wear is big; potentiometer surface easily produces and accumulates electrostatic; accumulation of static electricity reaches to a certain degree; will discharge; serious may cause inflammable and explosive substances on fire or blast, and, under the weather environment being more dried; human body usually can be with electrostatic; when people with gather too many static fine time go contact time, there is certain dangerous factor, electrostatic interaction also can bring certain harm to human body.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of antistatic potentiometer, it is possible to is prevented effectively from surface accumulation and produces electrostatic, eliminates the infringement that potentiometer is produced by electrostatic interaction.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of antistatic potentiometer, it is characterized in that, including: housing, described housing includes lower house, upper shell, it is provided with anti-static coating in described housing outer surface, described upper shell top is provided with axle sleeve, a cavity is formed between described lower house and upper shell, described cavity inside is provided with rotating shaft, conduction revolving fragment, first fixed pin sheet, second fixed pin sheet, dynamic pin sheet and circular arc resistance body, described rotating shaft matches with described axle sleeve, described rotating shaft includes metal inside and non-graphite outer layers, the first described fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body.
In a preferred embodiment of the present invention, described anti-static coating is conductive polyaniline composite nano-coating.
In a preferred embodiment of the present invention, described non-graphite outer layers is expanded graphite.
In a preferred embodiment of the present invention, it is connected by epoxide-resin glue is gluing between described metal inside and non-graphite outer layers.
The invention has the beneficial effects as follows: potentiometer provided by the present invention can be prevented effectively from surface accumulation and produce electrostatic, eliminates the infringement that potentiometer is produced by electrostatic interaction.
