Abstract

The invention discloses a high-precision helical potential device. The high-precision helical potential device comprises a resistor body, a resistor ligand and a resistor pointer, wherein the resistor body and the resistor ligand are provided with a first thread and a second thread, respectively, and the resistor ligand drives the resistor pointer to move along the first thread on the surface of the resistor body, so that an output resistance value of the high-precision helical potential device can be changed. Compared with the prior art that a resistor pointer moves along the linear direction of a resistor body, the high-precision helical potential device provided by the embodiment of the invention has the advantages that the precision of the output resistance value of the high-precision helical potential device can be improved, and the requirement on the precision of a variable resistor in the fields of precision control and precision measurement can be met.

Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to a high-precision spiral potentiometer. Background technique [0002] In the prior art, variable resistors have been widely used, such as changing the characteristics of signal generators, dimming lights, starting motors or controlling its speed, etc., which usually include resistors, movable contacts and three leads. foot. Two of the fixed pins are connected to both ends of the resistor body, and the other pin (center tap) is connected to the movable contact piece, and the movable contact piece moves linearly along the resistor body to change the resistance at both ends of the resistor body. In the fields of precision control and precision measurement, it is difficult for the existing variable resistors to meet the precision requirements. [0003] Based on this, it is necessary to provide a high-precision spiral potentiometer to meet the precision requirements of...
