Abstract
It is a kind of permanent magnet induction switch device that is especially suited for magnetic-electric information transition. An shield hood has magnetic conduction holes surround the case, two couple of electrode are fixed on upper and lower side in the case, a restoration unit and two short-circuit chips are fited between the electrodes, a permanent magnet is set between the short-circuit chips, its magnet poles straight correspond to the magnetic conduction holes, each electrode is led out of the case by wire. The switch condition of the device reflects outer magnet polarity by the action of outer magnetic force in different polarity. With higher anti-electromagnetic interference capability, it can be used for the fields of digit circuit and auto-control extensively.
Description
The present invention is a kind of Permanent-magnetic induction switch device.
Existing magnetic induction device, they can only reflect tested magnet magnetic flux size to comprise " 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, Chinese patent CN89781Y is because its design is perfect not to the utmost, anti-other magnetic disturbance ability is relatively poor, so when outer magnetic pole information dense arrangement, its service efficiency is subjected to bigger restriction.
The purpose of this invention is to provide the switching device that a kind of anti-other magnetic disturbance can reflect tested permanent magnet polarity.
The object of the present invention is achieved like this: in the middle of two groups of double-contact electrodes, drive two short-circuit pieces interlocks with a permanent magnet in the magnetic shielding cover of magnetic conductive hole is arranged.The outer magnetic line of force acts on permanent magnet by magnetic conductive hole, under the effect of magnetic opposed polarity magnetic force, makes short-circuit piece connect one group double-contact electrode respectively outside, and the folding condition of each contact electrode directly reflects the polarization state of outer magnetic.
There is a resetting means can make permanent magnet can recover original state automatically when magnetic disappears outside.Permanent magnet pole is perpendicular to magnetic conductive hole.Magnetic shielding cover is with stopping that the material of magnetic penetration power makes.
The present invention is output as two kinds of on off states with two kinds of polarity of the outer magnet tested, is easy to realize that the magnetoelectricity mode changes.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 present invention can be widely used among digital circuit and the automation field.Owing to adopted magnetic shielding cover, avoided the interference effect of other magnetic, so improved magnetic information arranging density and service efficiency.
Accompanying drawing is a fragmentary cross-sectional view of the present invention.
The concrete structure of invention is provided by following embodiment and accompanying drawing: magnetic shielding cover (1) surrounds insulation shell (2); Interior top of housing (2) and bottom divide two groups to be fixed with four contact electrode (3), (4), (9) (10); Spring reverse motion (8) and two short-circuit pieces (5), (7) are housed between two groups of fixed electrodes, permanent magnet (6) is housed between short-circuit piece (5), (7), its magnetic pole is over against answering magnetic conductive hole (11).Two groups of four electrodes are open-circuit condition .d1 among the figure when no outer magnetic pole signal, and d2, d3, d4 are the lead-out wire of each contact electrode (4) (9), (10), (3).
The outer magnetic line of force enters and acts on permanent magnet (6) along the magnetic conductive hole (11) of arrow indication, permanent magnet (6) and short-circuit piece (5), (7) interlock; For example, when the outer magnetic line of force and permanent magnet (6) when polarity is identical (all being the South Pole), under the effect of magnetic repulsive interaction, short-circuit piece (7) and electrode (9), (10) short circuit conducting; When the outer magnetic line of force and permanent magnet (6) when polarity is different, short-circuit piece (5) and electrode (3), (4) short circuit conducting under the mutual suction of magnetic; After outer magnetic force disappears, under the effect of spring reverse motion (8), drive permanent magnet (6) and recover each electrode open-circuit condition with short-circuit piece (5), (7); When detecting the outer magnet polarity chron, the outer magnetic line of force acts on permanent magnet (6) by magnetic conductive hole (11), if d1 and d4 conducting, then outer magnetic pole is the arctic, otherwise d2 and d3 conducting then outer magnetic pole be the South Pole.The magnetic line of force that does not act on magnetic conductive hole is then stopped by magnetic shielding cover (1), can not have an effect to permanent magnet (6), and this has just produced the effect of anti-other magnetic disturbance.
Claims (2)
1. magnetic induction switch device, this device comprises housing (2), and interior top of housing (2) and bottom are fixed with electrode (3), (4), (9), (10) elasticity reset device (8) and short-circuit piece (5), (7) are housed between fixed electrode (3), (4) and (9), (10); Housing is drawn by lead d1, d2, d3, d4 respectively in each electrode (4), (9), (10), (3); It is characterized in that: a slice permanent magnet (6) is arranged between short-circuit piece (5), (7), have a magnetic shielding cover (1) to surround housing (2).
