Abstract
The invention discloses a damp-proof potentiometer which comprises a shell .The shell comprises a lower shell body and an upper shell body .The shell is composed of an inner metal layer and an outer damp-proof layer .A shaft sleeve is arranged on the top of the upper shell body .A cavity is formed between the upper shell body and the lower shell body .A rotating shaft, an electric conduction rotating piece, a first fixed pin connection piece, a second fixed pin connection piece, a movable pin connection piece and an arc resistor are arranged inside the cavity .The rotating shaft is matched with the shaft sleeve .The rotating shaft comprises an inner metal core and an outer graphite layer .The first fixed pin connection piece and the second fixed pin connection piece are connected to the two ends of the arc resistor respectively .In this way, the damp-proof potentiometer has the good dampness resistance and good lubrication level, and effectively prevents external dampness from invading the potentiometer.
Description
Technical field
The present invention relates to potentiometer field, particularly relate to a kind of damp-proof potentiometer.
Background technology
Potentiometer be there are three exits, resistive element that resistance can be regulated by certain Changing Pattern, potentiometer is generally made up of resistive element and moveable brush.Potentiometer is installed in enterprising enforcement of various equipment and uses, play regulation effect, existing rotational potentiometer lubricity is poor, fretting wear is big, when potentiometer uses environment moister, inside it, be easily accessible a small amount of dampness, long-time after easily cause the oxidation of getting rusty of the more internal metal parts of potentiometer, it is substantially reduced the normal service life of potentiometer, thus increases use cost.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of damp-proof potentiometer, it is possible to having preferable humidity resistance, lubricity is good, is prevented effectively from outside moisture and invades inside potentiometer.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of damp-proof potentiometer, it is characterized in that, including: housing, described housing includes lower house, upper shell, described housing is made up of inner metallic layer and moistureproof outer layer, described upper shell top is provided with axle sleeve, a cavity is formed between described lower house and upper shell, described cavity inside is provided with rotating shaft, conduction revolving fragment, first fixed pin sheet, second fixed pin sheet, dynamic pin sheet and circular arc resistance body, described rotating shaft matches with described axle sleeve, described rotating shaft includes metal inside and non-graphite outer layers, the first described fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body.
In a preferred embodiment of the present invention, described moistureproof outer layer is moist-proof board.
In a preferred embodiment of the present invention, described inner metallic layer is connected by gluing with moistureproof outer layer.
In a preferred embodiment of the present invention, described non-graphite outer layers uses soft graphite.
In a preferred embodiment of the present invention, described metal inside is connected by epoxide-resin glue is gluing with non-graphite outer layers.
The invention has the beneficial effects as follows: damp-proof potentiometer provided by the present invention has preferable humidity resistance, and lubricity is good, is prevented effectively from outside moisture and invades inside potentiometer.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:

Described moistureproof outer layer 4 is moist-proof board, can completely cut off the dampness in air and invade.
Described inner metallic layer 3 is connected by gluing with moistureproof outer layer 4.
Described non-graphite outer layers 8 uses soft graphite, this graphite in addition to having the characteristics such as the chemical stability of native graphite, anti-erosion, also to have special flexibility and elasticity, good airproof performance, and lubricity is high.
Described metal inside 7 is connected by epoxide-resin glue is gluing with non-graphite outer layers 8.
Damp-proof potentiometer provided by the present invention has preferable humidity resistance, and lubricity is good, is prevented effectively from outside moisture and invades inside potentiometer.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
