Abstract
The invention discloses an organic solid core potentiometer. The potentiometer comprises a lower base and an upper lid; formed a cavity between the base and the cover of the lower body, the shaft is disposed inside the cavity, the conductive rotary piece, first fixed pin sheet, the second fixed pin sheet, moving pin sheet and arc-shaped resistive element; having an arc-shaped grooves on the lower base, in cross-section of the arc-shaped groove isosceles trapezoid, including the bottom, bottom and back side at the bottom edge of the arc-shaped groove of the opening on the arc-shaped resistor element is a resistance powder compression molding in an arc-shaped recess slot, making the cross-sectional arc-shaped resistor also isosceles trapezoid; the cover is fixed to the body wall dry pack.
Description
Technical field
The present invention relates to potentiometer technical field, particularly relate 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.
Summary of the invention
The technical problem that the present invention 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 present invention 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 a preferred embodiment of the present invention, the high scope of described isosceles trapezoid is 3 ~ 5 millimeters.
In a preferred embodiment of the present invention, the length on the upper base of described isosceles trapezoid is 8 ~ 10 millimeters.
In a preferred embodiment of the present invention, the length of the bottom of described isosceles trapezoid is 13 ~ 15 millimeters.
The invention has the beneficial effects as follows: the organic solid potentiometer of the present invention, simple and reasonable, the stabilized structure of resistive element, can not come off from pedestal, offset, and serviceability is good.
