Description
Technical field
The invention belongs to relay technical fields, more particularly to a kind of magnetic latching relay.
Background technique
Relay is a kind of electronic control device, plays the work such as automatic adjustment, safeguard protection, conversion circuit in circuit
With its working principle is to add certain voltage at coil both ends, will pass through certain electric current in coil, thus in magnetic circuit
Upper generation galvanomagnetic-effect, armature will overcome the pulling force of return spring to be drawn to iron core under the action of electromagnetic attracting force, thus band
The stationary contact on movable contact and quiet spring on dynamic spring is attracted, and reaches conducting effect in circuit；
And with energy-saving and environment-friendly needs, magnetic latching relay will be used wider and wider, it is more and more it is general after
Electric appliance needs expand out magnetic and keep specification, and typical clapper type relay will realize that magnetic is kept, generally by iron core (or yoke)
It is divided into two parts, seals in a permanent magnet in centre, form tandem type magnetic circuit, after coil stimulating, magnetic circuit closure, permanent magnet
The magnetic force of generation can be such that armature is kept closed；The magnetic holdingization technology of existing clapper-type magnetic circuit system is to install magnet steel
(there are yoke integration and yoke to divide riveting two ways) on yoke, such as notification number are as follows: the Chinese patent of CN103426690B
File discloses a kind of magnetic latching relay of parallel connection type magnetic circuit, the disadvantage is that leaving coil for due to the influence of yoke and magnet steel
Space become smaller, cause coil power needs become larger；In addition, since yoke needs and ability after coil and the whole riveting of iron core progress
It can be packed into relay base, the presence of magnet steel and auxiliary yoke iron increases the difficulty of production technology, is unfavorable for the implementation of automation.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of magnetic latching relay, the actuation end of iron core has pole
The upper surface of boots, the pole shoe has protrusion or groove, passes through the protrusion or the upper surface structure of the groove and the pole shoe
At difference in height adjust the magnetic circuit gap between the iron core and armature, to realize magnetic circuit in the attraction and reset of armature
The balance of power；Armature is equipped with magnet steel, the coil of relay is powered, and iron core generates electromagnetic force and is attracted armature, at this time magnet steel
Magnetic circuit is also closed, and electromagnetic force disappears after coil blackout, and the magnetic circuit of magnet steel (permanent magnet) is closed always, to realize the armature
It is attracted and keeps.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of magnetic latching relay, including yoke
Iron, armature and iron core, the armature are connect with the yoke by elasticity of spring leaf, and the iron core winding has coil, the iron core
Actuation end there is pole shoe, the upper surface of the pole shoe has protrusion or groove, by the protrusion or the groove with it is described
Difference in height that the upper surface of pole shoe is constituted adjusts the magnetic circuit gap between the iron core and armature, to realize magnetic circuit in armature
Attraction and reset force balance；
The armature is equipped with magnet steel, and the magnet steel is corresponding with the position of the iron core, the magnet steel and the iron core
Position is corresponding, and the coil is powered, and iron core generates electromagnetic force and is attracted armature, and the magnetic circuit closure of the magnet steel, coil are disconnected at this time
The magnetic circuit of magnet steel remains closed after electricity, to realize that the actuation of the armature is kept.
It further says, the armature has mounting groove, and the magnet steel is fixedly installed in the mounting groove.
It further says, the mounting groove is located at the side of the armature.
It further says, the mounting groove is located at the upper surface of the armature.
It further says, including magnetic guiding frame, one end of the magnetic guiding frame is fixedly connected on the armature, and the other end and institute
Stating has gap between armature, the magnet steel is fixedly installed in the gap.
It further says, the side of the pole shoe has notch, adjusts the iron core to the armature by the notch
Attraction.
It further says, the notch is located at the same side with the raised or described groove and the two is adjacent.
It further says, the yoke is L shape, and the L-shaped yoke includes horizontal yoke and vertical yoke, the iron core
It is riveted with the horizontal yoke, one end of the reed is fixedly connected with the vertical yoke, the other end of the reed and institute
Armature is stated to be fixedly connected.
Beneficial effects of the present invention:
The iron core of relay of the invention has pole shoe, and the upper surface of the pole shoe has protrusion or groove, by described
The difference in height that the upper surface of the raised or described groove and the pole shoe is constituted adjusts between the magnetic circuit between the iron core and armature
Gap, to realize magnetic circuit in the attraction of armature and the balance (really adjusting set voltage and resetting voltage) of reset force；Pole
There is notch, by this notch (size) come the attraction of auxiliary adjustment relay on boots；Because according to magnetic circuit principle, iron core
The area of pole shoe is smaller, then it is bigger in attraction of the armature set position to armature, then the resetting voltage needed for resetting it
Also bigger, so as to balance resetting voltage numerically as far as possible with set voltage.
Invention relay, armature are equipped with magnet steel, and magnet steel is corresponding with the position of iron core, and the coil of relay is powered,
Iron core generates electromagnetic force and is attracted armature, and the magnetic circuit of magnet steel is also closed at this time, and electromagnetic force disappears after coil blackout, magnet steel (permanent magnetism
Body) magnetic circuit be closed always, thus realize the armature actuation keep (magnetic holding)；
Magnet steel and armature are subjected to integrated combination, its advantage is that existing electromagnetic relay coil yoke part is without doing more
Change, coil space is constant can to reduce coil power dissipation, while realizing specification electromagnetic relay coil combination of the same race and keeping with magnetic
Relay coil combination shares；In addition, since armature is the part of individualism, it only need to be after coil be partially loaded pedestal
Armature is loaded onto, without being riveted, the implementation that more conducively automates.
