Abstract
The utility model discloses a magnetic induction switch which belongs to a permanent magnetic induction switch and particularly suitable for magnetic-electric information transition. The utility model comprises a casing; two fixed electrode pieces are arranged on the upper and lower part in the casing; a piece of circular film with wave pattern whose edge is fixed on the casing is arranged between the two fixed electrode pieces; two movable electrode pieces and a piece of permanent magnet are relatively fixed on the center of the film; each of the electrodes is provided with a conducting wire which is led out of the casing. Under the actions of external magnetic force with different polarities, the external magnetic polarity can be reflected by the state of the switch. The utility model can be used in the fields of digital circuit and auto-control as a magnetoelectric conversion device.
Description
The utility model is a kind of invention of Permanent-magnetic induction switch device.
Existing magnetic induction device, comprise that they can only reflect tested magnet magnetic flux size to " magnetoresister; magnetodiode; magnetic sensitive transistor " (selecting from " State Standard of the People's Republic of China's electric diagram graphic symbol " GB4728.5-85), magnetic field intensity, and can not reflect its polarization state.
The purpose of this utility model provides a kind of switching device that can reflect tested permanent magnet polarity.
The purpose of this utility model is achieved in that in one group of two-way contact switch, with a permanent magnet and moving contact interlock.Under the effect of magnetic opposed polarity magnetic force outside of this magnet, make moving contact connect one of two-way contact respectively, the on off state of two-way contact directly reflects the polarization state of outer magnetic.
There is a resetting means can make permanent magnet can recover the original state permanent magnet pole automatically perpendicular to moving, fixed electrode contact-making surface when magnetic disappears outside.What the electrode in the two-way contact switch was used is not to be subjected to magneto motive conductor material.Each electrode is not subjected to magneto motive lead to draw housing.
The utility model is output as two kinds of on off states with two kinds of polarity of the outer magnet tested, is easy to realize the magnetoelectricity formal transformation.Both convenient expression outer magnetic pole is also introduced the binary number notion easily, and these two kinds of on off states are represented " 1 " and " 0 " respectively.The utility model can be widely used among digital circuit and the automation field.
The concrete structure of utility model is provided by following drawings and Examples.
Accompanying drawing is according to profile of the present utility model.Describe concrete structure and working condition below in detail: this device comprises a housing (1); Two circular fixed electrodes (2), (7) are arranged in the housing; Two circular moving electrodes (3), (6) are arranged; The fixing circular ripple glaze film (4) of a slice is arranged; A circular permanent magnet (5) is arranged, and its South Pole upwards.Two moving electrode parallel connections are as output among the figure.Moving electrode and two-way fixed electrode are off-state when static.D1, d2, d3, d4 are the lead-out wire of each electrode.
Outer magnetic force (8) enters and acts on permanent magnet (5) from the sensing hole of arrow indication, permanent magnet (5) and moving electrode (3), (6) interlock; When outer magnetic force (8) and magnet (5) when polarity is identical (all being the South Pole), moving point (6) contacts conducting with fix a point (7); When outer magnetic force (8) and magnet (5) when polarity is different, moving point (3) contacts conducting with fix a point (2); After outer magnetic force (8) disappeared, permanent magnet (5) drove moving contact (3), the state when (6) recover static simultaneously under the elastic force effect of circular ripple glaze film (4).
For example: when detecting the outer magnet polarity chron, the outer magnetic line of force acts on permanent magnet (5) by sensing hole; If d1 and d3 conducting, then outer magnetic pole is the arctic; Otherwise d2 and d4 conducting, then outer magnetic pole is the South Pole.
