Magnetic fluid micro-control knob and combination method thereof

Abstract

The invention relates to a high-accuracy microcontrol knob, in particular to a magnetofluid microcontrol knob and a combining method thereof. The magnetofluid microcontrol knob comprises a knob body, a magnetofluid mixed liquid, a distributing plate and an external wiring terminal; the knob body comprises a handle, an accommodating groove and an electromagnetic induction coil, the accommodating groove comprises an electricity passing channel arranged in the electromagnetic induction coil, the magnetofluid mixed liquid is accommodated in the groove, and the handle is connected with two ends of the accommodating groove; the magnetofluid mixed liquid is obtained by mixing conductive metal nanoparticles in a temperature-sensing insulated magnetic fluid and keeping the mixture in a uniformly mixed state; the distributing plate is divided into multiple intervals, and the knob body rotates relative to the distributing plate; each wiring end of the external wiring terminal is correspondingly connected with each interval of the distributing plate. The knob can be rapidly assembled according to the principle and the basic structure. By comparison with the prior art, switch selection and fine adjustment of the knob can be realized by means of the magnetofluid mixed liquid, a magnetofluid has lubricating, sealing and heat dissipation functions, and the accuracy, the stability and the reliability of a knob switch can be improved.

Description

technical field [0001] The invention relates to a high-precision micro control knob, in particular to a magnetic fluid micro control knob and a combination method thereof. Background technique [0002] As a common electronic component that controls circuit closure, switching and disconnection, the knob can be seen everywhere in our daily life. At present, with the increasing demand for global power transmission and distribution equipment and its components, it also drives the rapid development of my country's power transmission and distribution equipment. However, at present, our country has overcapacity in low-end products, but there is no breakthrough innovation in high-end product technology. At present, the knobs on the market are prone to failure forms such as corrosion, wire slipping, blockage, and thread breakage. Therefore, a knob switch with higher precision and better reliability is urgently needed. Contents of the invention [0003] The purpose of the present ...
