The invention discloses a rotary shaft potentiometer with good sealing performance. The rotary shaft potentiometer comprises a lower housing and an upper housing, wherein a cavity is formed between the lower housing and the upper housing; a rotary shaft, a conductive rotary sheet, a first fixed connecting pin sheet, a second fixed connecting pin sheet, a movable connecting pin sheet and an arc-shaped resistor are arranged in the cavity; the first fixed connecting pin sheet and the second fixed connecting pin sheet are connected to two ends of the arc-shaped resistor respectively; a shaft sleeve is arranged on the upper housing; the rotary shaft is matched with the shaft sleeve; a round groove is formed in the bottom of the lower housing; a first seal ring groove, a second seal ring groove and a third seal ring groove are formed in the inner wall of the shaft sleeve; a first seal ring is arranged in the first seal ring groove; a second seal ring is arranged in the second seal ring groove; a third seal ring is arranged in the third seal ring groove; and the upper housing is connected with the lower housing through a bolt, and a rubber seal gasket is arranged at the joint. Therefore, the rotary shaft potentiometer is simple and reasonable in structure and has relatively excellent seal performance; and the use performance of the potentiometer is ensured.
Description
technical field [0001] The invention relates to the technical field of potentiometers, in particular to a rotary shaft potentiometer with good sealing performance. Background technique [0002] The potentiometer is a resistive element with three terminals and the resistance value can be adjusted according to a certain change rule. A potentiometer usually consists of a resistor body and a movable brush. [0003] Potentiometers are installed on various devices for adjustment. The sealing performance of the potentiometer is closely related to the service life of the potentiometer. If the sealing performance is not good, dust and water vapor will enter the interior of the potentiometer, reducing the service life of the potentiometer. Contents of the invention [0004] The technical problem mainly solved by the invention is to provide a shaft potentiometer with good sealing performance, which has a simple and reasonable structure, has better sealing performance, and ensures t...
