高精度螺旋电位装置
摘要：
本发明公开了一种高精度螺旋电位装置，包括电阻本体、电阻配合体和电阻指针，通过分别在电阻本体和电阻配合体上设置第一螺纹和第二螺纹，使电阻配合体带动电阻指针在电阻本体表面沿所述第一螺纹移动，从而改变高精度螺旋电位装置的输出电阻值。对比现有技术中的电阻指针沿电阻本体直线方向移动，本发明实施例提供的高精度螺旋电位装置提高了高精度螺旋电位装置的输出电阻值的精度，能够满足在精密控制和精密测量领域对可变电阻器精度的要求。
摘要（英）：

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.
