Abstract
The invention discloses a moisture-proof potentiometer, which comprises a lower shell and an upper shell, wherein a hollow cavity is formed between the lower shell and the upper shell; a rotating shaft, a conductive rotating plate, a first fixed pin sheet, a second fixed pin sheet, a movable pin sheet and a circular-arc resistor body are arranged in the hollow cavity; the first fixed pin sheet and the second fixed pin sheet are respectively connected to two ends of the circular-arc resistor body; a plurality of hygroscopic moisture-proof structures are distributed on the upper shell; each hygroscopic moisture-proof structure comprises a groove which is formed in the inner wall of the upper shell; a powdery drying agent is accommodated in each groove; and an opening of each groove is covered through a gauze. In the manner, the moisture-proof potentiometer is simple and reasonable in structure and has good moisture-proof performance; and the service lifetime of the potentiometer is prolonged.
Description
Technical field
The present invention relates to potentiometer technical field, particularly relate to a kind of damp-proof potentiometer.
Background technology
Potentiometer be there are three exits, resistive element that resistance can regulate by certain Changing Pattern.Potentiometer is made up of resistive element and moveable brush usually.
Potentiometer is installed in the enterprising enforcement use of various equipment, plays regulating action.When potentiometer environment for use is moister, its inside easily enters a small amount of moisture, easily causes the oxidation of getting rusty of the more inner metal partss of potentiometer, greatly reduces the normal service life of potentiometer, thus increase use cost after long-time.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of damp-proof potentiometer, simple and reasonable, has good humidity resistance, adds the useful life of potentiometer.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of damp-proof potentiometer, comprise: lower house and upper shell, cavity is formed between described lower house and upper shell, described cavity inside is furnished with rotating shaft, conduction revolving fragment, first fixed pin sheet, second fixed pin sheet, dynamic pin sheet and circular arc resistance body, described first fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body, described upper shell is distributed with multiple moisture absorption moisture-proof construction, described moisture absorption moisture-proof construction comprises the groove be arranged in upper enclosure inner wall, described inside grooves has Powdered drier, described slot opening place is covered by gauze.
In a preferred embodiment of the present invention, described groove is downward-sloping groove.
In a preferred embodiment of the present invention, described gauze is pasted onto in the upper enclosure inner wall at slot opening place by viscose.
In a preferred embodiment of the present invention, the inwall of described lower house has multiple moisture absorption moisture-proof construction.
The invention has the beneficial effects as follows: damp-proof potentiometer of the present invention, simple and reasonable, there is good humidity resistance, add the useful life of potentiometer.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of damp-proof potentiometer one of the present invention preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, lower house, and 2, upper shell, 3, groove, 4, Powdered drier, 5, gauze.

Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of damp-proof potentiometer, comprise: lower house 1 and upper shell 2, cavity is formed between described lower house 1 and upper shell 2, described cavity inside is furnished with rotating shaft, conduction revolving fragment, the first fixed pin sheet, the second fixed pin sheet, dynamic pin sheet and circular arc resistance body, and described first fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body.
Described upper shell 1 is distributed with multiple moisture absorption moisture-proof construction, described moisture absorption moisture-proof construction comprises the groove 3 be arranged on upper shell 1 inwall, described groove 3 inside has Powdered drier 4, described groove 3 opening part is covered by gauze 5, when potentiometer uses in wet condition, wetlyly unavoidably enter into potentiometer inside, a small amount of moisture now entering potentiometer inside is sponged by Powdered drier 4, effectively extends the useful life of potentiometer.
Preferably, described groove 3 is downward-sloping groove, avoids Powdered drier 4 to spill.
Preferably, described gauze 5 is pasted onto in the upper enclosure inner wall of groove 3 opening part by viscose, is used for blocking Powdered drier 4, can not moisture-barrier be absorbed by Powdered drier 4 simultaneously.
Preferably, the inwall of described lower house has multiple moisture absorption moisture-proof construction.
The invention has the beneficial effects as follows: damp-proof potentiometer of the present invention, simple and reasonable, there is good humidity resistance, add the useful life of potentiometer.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
