Abstract
The utility model discloses a dampproofing type potentiometre, include: lower casing and last casing, vacuole formation between lower casing and the last casing, cavity internal layout has pivot, electrically conductive revolving fragment, first fixed pin piece, the fixed pin piece of second, moves the pin piece and the ARC resistance body, the both ends at the ARC resistance body are connected respectively to the fixed pin piece of first fixed pin piece and second, the distribution has the dampproofing structure of a plurality of moisture absorptions on going up the casing, the dampproofing structure of moisture absorption is including setting up the recess on last shells inner wall, recess inside has powdered drier, groove opening covers through the gauze. In this way, the utility model has the advantages of simple and reasonable structure, have fine humidity resistance, increased the life of potentiometre.
Description
Technical field
The utility model relates to potentiometer technical field, particularly relates 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.
Utility model content
The technical problem that the utility model 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 utility model 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 the utility model preferred embodiment, described groove is downward-sloping groove.
In the utility model preferred embodiment, described gauze is pasted onto in the upper enclosure inner wall at slot opening place by viscose.
In the utility model preferred embodiment, the inwall of described lower house has multiple moisture absorption moisture-proof construction.
The beneficial effects of the utility model are: the utility model damp-proof potentiometer, simple and reasonable, have 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 utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, 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 the utility model damp-proof potentiometer one 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.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment 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 beneficial effects of the utility model are: the utility model damp-proof potentiometer, simple and reasonable, have good humidity resistance, add the useful life of potentiometer.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description 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 utility model.
Claims (4)
