Abstract
The utility model discloses an organic composition solid potentiometer, include: lower base and last lid, vacuole formation between lower base and the last lid, 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, a convex recess has down on the base, the transversal isosceles trapezoid that personally submits of convex recess, including last base, lower base and waist limit, go up the opening part that the base is convex recess, the ARC resistance body adopts resistance powder hot briquetting in convex recess for the cross section of the ARC resistance body also is isosceles trapezoid, be fixed with dry package on the internal wall of upper cover. In this way, the utility model has the advantages of simple and reasonable structure, the structure of resistive element is firm, can not follow the base and drop, squint, and performance is good.
Description
Technical field
The utility model relates to potentiometer technical field, particularly relates to a kind of organic solid potentiometer.
Background technology
Organic solid potentiometer is a kind of by electric conducting material and organic filler, and thermosetting resin is mixed with resistance powder, through hot pressing, and the real core resistive element that pedestal is formed.
In existing organic solid potentiometer, the fixed structure of resistive element on pedestal is unstable, easily occurs coming off, the phenomenon such as skew.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of organic solid potentiometer, simple and reasonable, and the stabilized structure of resistive element can not come off from pedestal, offset, and serviceability is good.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of organic solid potentiometer, comprise: bottom base and upper cover body, form cavity between described bottom base and upper cover body, 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;
Described bottom base has a circular groove, the cross section of described circular groove is isosceles trapezoid, comprise base, bottom and waist limit, described upper base is the opening part of circular groove, described circular arc resistance body adopts resistance powder hot-forming in circular groove, makes the cross section of circular arc resistance body also in isosceles trapezoid;
Described upper cover body inwall is fixed with dry bag.
In the utility model preferred embodiment, the high scope of described isosceles trapezoid is 3 ~ 5 millimeters.
In the utility model preferred embodiment, the length on the upper base of described isosceles trapezoid is 8 ~ 10 millimeters.
In the utility model preferred embodiment, the length of the bottom of described isosceles trapezoid is 13 ~ 15 millimeters.
The beneficial effects of the utility model are: the organic solid potentiometer of the utility model, simple and reasonable, and the stabilized structure of resistive element, can not come off from pedestal, offset, and serviceability is good.
