Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, not
For limiting the present invention.
As it is shown in figure 1, be the antistatic potentiometer schematic cross-section of the present invention.A kind of antistatic potentiometer, including housing 1
And the potentiometer main body 2 being arranged in housing 1；Described housing 1 uses cylindrical enclosed construction, and outer surface is provided with antistatic
Coating 1-4, it includes that upper shell 1-1 and lower house 1-2, described upper shell 1-1 top are provided with axle sleeve 1-3；Described potentiometer master
Body 2 includes that the carrier board 2-1 being loaded with resistance 2-2, described carrier board 2-1 are patty, and it is arranged on bottom above-mentioned housing 1；Institute
Stating resistance 2-2 is fold-line-shaped circular ring structure, and it is arranged on described carrier board 2-1 upper surface；It is additionally provided with on described carrier board 2-1
Sliding contact 2-3, described sliding contact 2-3 one end is fixed on described carrier board 2-1 center by contact support 2-4, another
End is slidably connected with described resistance 2-2；The fixing end of described sliding contact 2-3 is also connected with rotation bar 2-5, described rotation bar 2-
5 through described upper shell 1-1 top axle sleeve 1-3 and are arranged on described housing 1 central axis；Described rotation bar 2-5 includes gold
Belong to inner core and non-graphite outer layers.
The metal inside of the rotation bar 2-5 of the present invention and non-graphite outer layers are by gluing connection, and non-graphite outer layers is soft graphite,
There is the chemical stability of native graphite, anti-erosion, outside the characteristics such as lubricity is good, also there is special flexibility and elasticity, have one
Fixed sealing property.The anti-static coating 1-4 of the present invention is conductive polyaniline composite nano-coating, and conductive polyaniline is combined
Nano material, direct spraying or brush on housing, not only act as anti-static electrification, and adhesive force is high, low cost.
As in figure 2 it is shown, be potentiometer main body 2 top view of the present invention.The resistance 2-2 of the potentiometer main body 2 of the present invention is
Fold-line-shaped circular ring structure, its lines are uniformly or non-uniformly bar shaped, at the side near the carrier board 2-1 center of circle, its kink
