Passage is wire, heat dissipation channel then annular with the air line distance of charge tunnel as diameter.
Further, described distribution disk interior shape is the face of cylinder, and external shape is curved surface or cylinder, and interval number is
Even number.Distribution disk is mainly used in splitting different interval, and as when selecting switch, common interval number is even number, when knob conduct
During on and off switch, interval number determines according to the actual requirements.
Described magnetic fluid miniature control handle structure is relatively independent and simple, it is possible to Rapid Combination, and combined method is as follows:
S1 sets distribution disk according to the circuit number of required control, and point interval, position number is opened according to selection switch or power supply
Closing and set, the current/voltage according to using arranges and installs the electrode on distribution disk；
S2 prepares magnetic fluid mixed liquor, and a certain amount of copper nano particles is mixed into temperature-sensitive insulated magnetic fluid, and by protecting
Hold agent and keep its uniform admixture, mixed liquor is loaded in brown glass reagent bottle standby；
S3 sets containing tank according to actual needs, and including charge tunnel, charge tunnel selects straight line, broken line or curve
, charge tunnel is arranged in electromagnetic induction coil；
Knob is coordinated installation by S4 with distribution disk, and then magnetic fluid mixed liquor is full of containing tank, installs distribution disk electrode also
Seal；
S5 arranges external cabling terminal according to distribution disk interval, completes assembling.
Further, in described step S3, containing tank also includes heat dissipation channel, and heat dissipation channel is the straight line with charge tunnel
The annular that distance is diameter.
Further, in described step S4, need after completing to install to be come by the magnetic field intensity of regulation electromagnetic induction coil
Test knob performance.
This utility model realizes the assembling of copper nano particles by controlling magnetic field and dissociates, thus realizes closing of circuit
With the control disconnected.This utility model has the advantage that (1) compact conformation, can be miniaturized, may be used for precision instrument
Circuit controls；(2) design is simple, and each several part is relatively independent, maintains easily and overhauls；(3) there is good interchangeability, can realize
Modularity, seriation and quickly design；(4) switch of the present utility model to working environment without particular/special requirement, it is possible to adapt to various
Special environment.
Compared with prior art, this utility model uses the mixed liquor of copper nano particles and temperature-sensitive insulated magnetic fluid to come in fact
The selection now switched and knob fine setting, magnetic fluid has again good lubrication, sealing and heat sinking function simultaneously, improves knob and opens
