Abstract
The utility model discloses a coaxial precise multi-turn potentiometer, comprising a plurality of casings and a plurality of lead welding sheets, which are arranged at the casings. The casings are connected together by fasteners. A rotating shaft is arranged at the axes in the casings. The lower end of the rotating shaft is arranged in the shaft hole on the outer casing of the lower cover, which is connected with the lower part of the casings. The upper end of the rotating shaft stands out through the shaft hole which is positioned at the center of the upper cover. Each casing is provided with a winding pad inside. And an annular winding is arranged on each winding pad. The annular windings are connected with reeds by slip lap joint. The other ends of the reeds are fixedly connected with the reed brackets. The reed brackets are connected with the insulated shaft sleeves. The insulated shaft sleeves are fixedly arranged on the rotating shaft. The reed brackets are connected with the rotating shaft via collecting reeds. The lead welding sheets are connected the taps of the windings. The coaxial precise multi-turn potentiometer has the advantages of reasonable structural design, advanced technology, high adjustment precision, capacity for outputting multiple synchronous output signals; therefore, the function transform between output signals can be realized.
