Abstract
The invention declares a relay electric device which comprises a base bracket, and is characterized in that the upper end of the base bracket is in rotational connection with one end of a moving iron component, and the lower end thereof is connected with an electromagnetic coil with an iron core; a permanent steel magnet is cast in the moving iron component at the position corresponding to the iron core position; the electromagnetic coil and an external direct current supply form a closed control circuit; the other end of the moving iron component is fixedly connected with a contact switch which is used for controlling conducting of a normally open/ normally closed contact circuit. The electric device is simple in structure, and has low probability of failure; when the direct current supply of the device is not in connection with the electromagnetic coil, the permanent steel magnet and the iron core are directly in contact and absorption, the relay is stable and reliable in working; when the direct current supply of the device is in connection with the electromagnetic coil, the iron core generates galvanomagnetic effect, and the polarity of the magnetic field is the same with that of the permanent steel magnet, thereby generating a repulsion; and the relay works reliably and steadily at very smaller direct current, so that the energy saving effect is obvious.
Description
Technical field
The present invention relates to a kind of relay electric device.
Background technology
Traditional relay electric device generally is made up of iron core, coil, armature, contact reed etc.As long as add certain voltage at the coil two ends, will flow through certain electric current in the coil, 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 drives moving contact and fixed contact (normally opened contact) adhesive of armature.Behind coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return 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 to have on the contact of relay certain pressure could guarantee the relay reliably working after must overcoming the pulling force of return spring again, and the pull-back forces of spring is again maximum at this moment.The electric current that coil is logical is bigger like this, and energy resource consumption is more.
Summary of the invention
The object of the invention is at the deficiencies in the prior art, provides a kind of simple in structure, reliable operation, the relay electric device of saving cost.
The present invention adopts following technical scheme for achieving the above object:
A kind of relay electric device comprises base support, it is characterized in that: described base support upper end is rotationally connected with moving iron parts one end, and described base support lower end is connected with the solenoid that has iron core; The casting permanent-magnet steel corresponding with described iron core position in the described moving iron parts; Described solenoid and external dc power form 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.
It is further characterized in that, described permanent-magnet steel is Ru-Fe-B.
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 invention 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 that the same sex is repelled each other, the relay reliable and stable work, and the direct current that needs is less, and energy-saving effect is obvious.

S1 is in open circuit in dc source 5 systems, driving power E1 is not added on d-c solenoid 4, and iron-core coil 3 is equal to an iron block, Ru-Fe-B permanent-magnet steel 2 will with these iron core 3 phase adhesives, drive moving iron parts 1 motion, by 7 contacts of normally-closed contact switch, make E3, R2 circuit working.
S1 is in closed circuit in dc source 5 systems, driving power E1 will be added on d-c solenoid 4, iron-core coil 3 produces galvanomagnetic-effect, the polarity of the polarity in its magnetic field and Ru-Fe-B permanent-magnet steel 2 forms the repulsion of two like magnetic poles repel each other, drive moving iron parts 1 motion, by 6 contacts of normally opened contact switch, make E2, R1 circuit working.
Moving iron parts and the bearing underframe of this relay electric device can be suppressed with reinforced plastics, thereby save cost.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
