According to the magnetic tilting sensor, the magnetic tilting sensor is reliable and stable with the adoption of a magnetic conduction manner, can resist outside shaking interference and really reflects the object state.
Description
Technical field
The present invention relates to sensor field, specifically a kind of magnetic force falling sensor.
Background technology
In current technology, in order to the consideration of secure context, a lot of electrical equipment or apparatus have all installed dumping switch or falling sensor additional, on high-power, band heating, the electrical equipment of rotary device or apparatus, especially install that to topple over protection more general additional.When electrical equipment or apparatus are translated into, dumping switch can inform master chip to cut off the electricity supply, to reach the object of safeguard protection.Existing falling sensor mainly contains electromechanical and photo-electric two kinds.Electromechanical is mainly by steel ball, and the inner housing with conic guide, and switch contact composition, carry out detecting sensor attitude by the contact of steel ball and contact with disconnection.Photo-electric falling sensor is mainly made up of light-emitting tube, light receiving tube and ball, whether blocks light judge sensor attitude by ball.
The weak point of electromechanical falling sensor, one is can cause loose contact by the impact of humidity, temperature for a long time, two is that electrical equipment or apparatus operationally all can have vibrations, and the steel ball in sensor can be beated in the case of a shock, and such error signal will produce.Photo-electric falling sensor requires high to photoelectric tube installation site, thus assembling inconvenience, high expensive.
summary of the inventionthe object of this invention is to provide a kind of magnetic force falling sensor, loose contact can be caused and be easily subject to the deficiency that interference is rocked in the external world by the impact of humidity, temperature to solve current electromechanical falling sensor for a long time.
In order to achieve the above object, the technical solution adopted in the present invention is:
Magnetic force falling sensor, it is characterized in that: include solid housing, solid case top is provided with back taper guide groove in solid housing, bottom back taper guide groove, namely vertex of a cone place is provided with cylindrical groove, be provided with the magnetic bead of size and cylindrical groove form fit in cylindrical groove, solid case top is covered with top cover, and top cover is fixed with circuit board, four tongue tubes circuit board are equipped with, four tongue tube formation peripheral closure parallel with one another loops.
Described magnetic force falling sensor, is characterized in that: described solid shell material is non-iron-cobalt-nickel magnetic material.
Described magnetic force falling sensor, it is characterized in that: described solid housing is rectangle, solid case top corner location is respectively equipped with column type threaded hole, and top cover covers in solid case top, and top cover is arranged on solid housing by the nylon screw being screwed into column type threaded hole respectively.
The present invention devises a kind of magnetic force falling sensor, and this magnetic force falling sensor adopts the mode of magnetic force conducting reliable and stable, and can resist and extraneous rock interference, reflects the state of object really.

Fig. 2 is the solid shell structure sectional view of the present invention.
Fig. 3 is tongue tube johning knot composition in the present invention.
Embodiment
As shown in Figure 1-Figure 3, magnetic force falling sensor, include solid housing 11, solid housing 11 top is provided with back taper guide groove 9 in solid housing, bottom back taper guide groove 9, namely vertex of a cone place is provided with cylindrical groove 10, the magnetic bead of size and cylindrical groove 10 form fit is provided with in cylindrical groove 10, solid housing 11 top is covered with top cover, top cover is fixed with circuit board, four tongue tubes 1,2,3,4 circuit board are equipped with, four tongue tube 1,2,3,4 formation peripheral closure loops parallel with one another.
Solid housing 11 material is non-iron-cobalt-nickel magnetic material.
Solid housing 11 is rectangle, solid housing 11 top corner location is respectively equipped with column type threaded hole 5,6,7,8, top cover covers at solid housing 11 top, and top cover is arranged on solid housing by the nylon screw being screwed into column type threaded hole 5,6,7,8 respectively.
Tongue tube 1,2,3,4 parallel connection forms a peripheral closure loop, and peripheral closure loop is close on lid.It is to ensure arbitrary reed switch conduction that tongue tube arranges like this, a and b all can conducting.
The material of solid housing is the magnetic materials such as non-iron-cobalt-nickel, as nylon, and plastics.
Plastic casing inside is provided with back taper guide groove 9, is provided with cylindrical groove 10 bottom guide groove, have in guide groove one can be freely movable magnetic bead, plastic casing lid secures the circuit board that one piece of surrounding is equipped with tongue tube.When sensor levels is placed, magnetic bead is in the cylindrical groove 10 of bottom, and extraneous rocking can not allow magnetic bead leave cylindrical groove 10, the tongue tube not conducting on lid.When sensor perturbations falls certain angle (if more than 45 degree time, can set when this angle is produced), magnetic bead can leave cylindrical groove 10, is rolled on lid limit along back taper guide groove 9, and the tongue tube now on lid is by magnetic action and conducting.
Circuit board, lid and housing surrounding are provided with column type through hole 5,6,7,8, first magnetic bead are put into housing, cover lid during installation, circuit board is placed on lid, notice during placement that cylindrical hole will be corresponding to, after putting well, is installed to nylon screw in four cylindrical holes.
Whether the present invention can not only inspected object topple over, and the extraneous weak vibrations produced can be resisted, rely on the cylindrical groove that bottom is provided with, make magnetic bead when sensor levels is placed, be stabilized in groove, extraneous slight rocking can not cause magnetic bead to be shifted, and the design of circuit board at top can ensure the trigger switch when object falling, improve the instability that bottom is triggered, thus ensure reliability and the accuracy of falling sensor function.
