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.It 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 anticorrosion type potentiometer schematic cross-section of the present invention.A kind of anticorrosion type potentiometer, including
Housing 1 and the potentiometer main body 2 being arranged in housing 1；Described housing 1 uses cylindrical enclosed construction, and its inner surface is with outward
Surface is provided with rust-preventing film layer 1-2, and top is provided with axle sleeve 1-1；Described potentiometer main body 2 includes the carrier being loaded with resistance 2-2
Plate 2-1, described carrier board 2-1 is patty, and it is arranged on bottom above-mentioned housing 1；Described resistance 2-2 is fold-line-shaped annulus knot
Structure, it is arranged on described carrier board 2-1 upper surface；Being additionally provided with sliding contact 2-3 on described carrier board 2-1, described slip is touched
Point 2-3 one end is fixed on described carrier board 2-1 center by contact support 2-4, and the other end slides even with described resistance 2-2
Connect；The fixing end of described sliding contact 2-3 is also connected with rotation bar 2-5, and described rotation bar 2-5 passes through described upper shell 1-1 and pushes up
Portion axle sleeve 1-3 is simultaneously arranged on described housing 1 central axis.
The rust-preventing film layer 1-2 of the present invention uses the red alcohol acid antirust paint of Polyferric Sulfate, and Seiko baking brushing forms rust-preventing film layer, has
The property of rust resistance and corrosion resistance, it is to avoid potentiometer occurs aging because getting rusty.
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
Divide and be slidably connected with sliding contact 2-3, the different essences of potentiometer can be set by arranging the bending quantity of resistance 2-2 and degree
