Abstract
The utility model discloses a relay electric actuator which comprises a base support and is characterized in that the upper end of the base support is rotatably jointed with one end of a moving iron part; the lower end of the base support is connected with a solenoid with an iron core; permanent magnetic steel corresponding to the position of the iron core is casted inside the moving iron part; the solenoid and an external DC power source form a closed control circuit; and the other end of the moving iron part is fixedly connected with a contact switch for controlling breakover of a normally open or normally-closed contact circuit. The relay electric actuator provided by the utility model has a simple structure and is not easy to break down. When the solenoid is not connected to the DC power source of the device, the permanent magnetic steel and the iron core are directly contacted and attract each other, and a relay operates reliably and stably. When the solenoid is connected to the DC power source of the device, the iron core generates an electromagnetic effect, polarity of the magnetic field and polarity of the permanent magnetic steel form expulsive force as like poles repel, and the relay operates reliably and stably. Required direct current is low such that the energy-saving effect is obvious.
Description
Technical field
The utility model relates to a kind of relay electric device.
Background technology
Traditional relay electric device generally is comprised of iron core, coil, armature, contact reed etc.As long as add certain voltage at the coil two ends, in coil, will flow through certain electric current, thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring under the effect of electromagnetic attracting force inhales to iron core, thereby with moving contact and fixed contact (normally opened contact) adhesive of moving armature.After coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return to original position at the reaction force of spring, makes moving contact and original fixed contact (normally-closed contact) release.Adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.
But traditional relay is when adhesive, the electromagnetic force that armature produces will have certain the suction-combining force to guarantee on the contact of relay that certain pressure guarantee relay reliably working is arranged after must overcoming the pulling force of return spring again, and now the pull-back forces of spring is again maximum.The electric current that coil is logical like this is larger, and energy resource consumption is more.
The utility model content
The utility model purpose is for the deficiencies in the prior art, provides a kind of simple in structure, reliable operation, cost-saving relay electric device.
The utility model for achieving the above object, adopts following technical scheme:
A kind of relay electric device, comprise base support, it is characterized in that: described base support upper end and moving iron parts one end are rotationally connected, and described base support lower end is connected with the solenoid with cored; The casting permanent-magnet steel corresponding with described iron core position in described moving iron parts; Described solenoid and external dc power form the Closed control circuit; The other end of described moving iron parts is fixedly connected with that control is often opened or the contact switch of normally-closed contact circuit turn-on.
Further characterized in that, the permanent magnet is Ru Tiepeng .
It is further characterized in that, the thickness of described permanent-magnet steel is 5-6mm, and its sectional area is greater than the sectional area of described iron core.
It is further characterized in that, the described permanent-magnet steel spatial separation corresponding with described iron core is 2-3mm.
It is further characterized in that, described base support and moving iron parts are made by reinforced plastics.
Compared with prior art, relay electric device of the present utility model is simple in structure, and is difficult for breaking down; When this device DC power supply and solenoid were disconnected, permanent-magnet steel directly contacted the phase adhesive with iron core, the relay reliable and stable work; When this device DC power supply and solenoid connection, iron core produces galvanomagnetic effect, and the polarity in its magnetic field and the polarity of permanent-magnet steel form the repulsion of two like magnetic poles repel each other, the relay reliable and stable work, and the direct current needed is less, and energy-saving effect is obvious.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1, moving iron parts; 2, permanent-magnet steel; 3, iron core; 4, solenoid; 5, DC power supply; 6, normally opened contact switch; 7, normally-closed contact switch; 8, base support; 9, link pins.
Embodiment
A kind of relay electric device as shown in Figure 1, comprise base support 8, and described base support 8 upper ends and moving iron parts 1 one ends are rotationally connected by link pins, and described base support 8 lower ends are connected with the solenoid 4 with cored 3; The permanent-magnet steel 2 that the interior casting of described moving iron parts 1 is corresponding with described iron core 3 positions; Described solenoid 4 forms the Closed control circuit with external dc power 5; The other end of described moving iron parts 1 is fixedly connected with that control is often opened or the contact switch of normally-closed contact 6,7 circuit turn-ons.
A permanent electric relay apparatus 2 Ru-Fe-B magnet having a thickness of 5 ~ 6mm, the permanent magnet 2 is slightly larger than the cross-sectional area of the core cross-sectional area of the coil 3; E1 applied DC power solenoid 4, Ru Fe-B permanent magnet 2, the coil core 3 and the corresponding spatial distance in the 2-3, between mm.
When the DC power supply 5 system S1 is open, the driver is not added to the DC power supply E1 4 solenoid coil is equivalent to an iron core 3, Ru-Fe-B permanent magnet 2 will be combined with the attraction of the core 3, iron parts a movement led by the normally closed contact switch 7 contacts to make E3, R2 circuit.
When the DC power supply 5 system S1 is closed, the drive will be added to the DC power supply E1 electromagnetic coil 4, the coil core 3 generates electromagnetic effects, its magnetic polarity and Ru-Fe-B permanent magnet polarity formation of sex repulsion 2 repulsion, led a movement moving iron parts, normally open contact switch 6 through contact with so E2, R1 circuit.
Moving iron parts and the bearing underframe of this relay electric device can be suppressed with reinforced plastics, thereby cost-saving.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
