Abstract
The present invention relates to carbon-film potentiometer, including pedestal and the carbon film plate being laid on one surface of pedestal, drier coating is provided between the pedestal and carbon film plate, the drier coating can adsorb the moisture in carbon film plate in real time, avoid carbon film plate from the phenomenon of carbon film moisture regain occur due to long-time exposure, improve the service life of carbon-film potentiometer.
Description
Technical field
The present invention relates to potentiometer technical field, more particularly, to a kind of carbon-film potentiometer.
Background technology
Carbon-film potentiometer is applied on horseshoe-shaped paper offset plate made of last layer carbon film, its change in resistance and Interposer contact
The relation of position has linear, logarithmic and three kinds exponential, and carbon-film potentiometer has large-scale, small-sized, miniature several, some and opens
Close the potentiometer for forming belt switch together, the characteristics of carbon-film potentiometer is that high resolution, wearability are good, and long lifespan, but logical
Normal carbon-film potentiometer possesses following shortcoming：Carbon film plate on carbon film device easily adsorbs the vapor in air so as to carbon film occur
The phenomenon of piece humidity, influences performance, reduces the service life.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of humidity resistance is good, and the carbon film current potential of service life length
Device.
The technical solution adopted in the present invention is carbon-film potentiometer, including pedestal and is laid on one surface of pedestal
Carbon film plate, drier coating is provided between the pedestal and carbon film plate.
The beneficial effects of the invention are as follows：Drier coating is set between pedestal and carbon film plate, which can be with
Moisture in absorption carbon film plate in real time, avoids carbon film plate from the phenomenon of carbon film moisture regain occur due to long-time exposure, improves carbon
The service life of membrane potentiometer.
As priority, the area coverage of the drier coating, can be with using the structure at least equal to the surface area of carbon film plate
Maximumlly using drier coating come to carbon film plate carry out it is moisture-proof, avoid carbon film plate become damp influence use.
As priority, the carbon film plate of carbon-film potentiometer includes a cylindrical segmental arc and is covered in cylindrical segmental arc Shangdi drying
Agent bar, using the structure, can with further improving carbon-film potentiometer humidity resistance, use the longevity with improving carbon-film potentiometer
Life.
As priority, carbon-film potentiometer, which further includes, is separately positioned on the fixed touching plate at pedestal both ends, is arranged on base central
The slide and the movable contact spring that is connected with revolving dial of one end of revolving dial, one end and revolving dial connection, slide it is another
One end is touched with carbon film plate patch, and using the structure, movable contact spring drives slide to rotate by moving, so as to change carbon-film potentiometer
Resistance value come achieve the purpose that change circuit Current Voltage.
As priority, fixed touching plate and movable contact spring use metal material, and the outer surface of fixed touching plate and movable contact spring covers
There is antioxidation coating, using the structure, can prevent that carbon-film potentiometer usage time is long and the phenomenon for the aging that occurs getting rusty, improve
The service life of carbon-film potentiometer.
