It further says, the armature has mounting groove, and the magnet steel is fixedly installed in the mounting groove.
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 actuation end of the iron core has pole shoe.
It further says, the mounting groove is located at the upper surface of the armature.
It further says, the mounting groove is located at the side of the armature.
The utility model has the beneficial effects that
The utility model magnetic maintenance mechanism, armature are equipped with magnet steel, and magnet steel is corresponding with the position of iron core, the line of relay
Circle is powered, and 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, magnetic
The magnetic circuit of steel (permanent magnet) is closed always, to realize that the actuation of the armature keeps (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.

Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Embodiment: a kind of magnetic holding structure of electromagnetic relay, includes yoke 1, armature 2 and iron core 3, institute as shown in Figure 1:
Armature and the yoke are stated by 4 elastic connection of reed, the iron core winding has coil (not shown go out), it is characterised in that: institute
It states armature and magnet steel 5 is installed, the magnet steel is corresponding with the position of the iron core, and the magnet steel is corresponding with the position of the iron core,
The coil is powered, and iron core generates electromagnetic force and is attracted armature, at this time the magnetic circuit closure of the magnet steel, magnet steel after coil blackout
Magnetic circuit remains closed, to realize that the actuation of the armature is kept.
