Abstract
The utility model provides a magnetic latching relay comprising a substrate, a magnetic circuit system and a contact system, wherein the magnetic circuit system comprises a coil, a yoke, a movable iron core, a static iron and magnetic steels; the contact system comprises a movable contact combination and a static contact combination; the contact system and the magnetic circuit system are arranged side by side in the substrate, and are connected through a push sheet; three magnetic steels are arranged in the contact system; two of the three magnetic steels are arranged between the coil and the yoke, and the other magnetic steel is arranged in the substrate and one side of the top of the movable iron core; the magnetic steels are made from permanent magnet materials; and the structure has three magnetic return paths during the whole on-off state and the conversion process. As the requirements for parts and resetting are lower during the production process, the magnetic circuit system is easy to realize free setting effect; and as the magnetic retention and the contact pressure are higher, the anti-interference capacity for the external magnetic field force and the anti-instantaneous overcurrent capacity are relatively higher.
Description
Technical field
The utility model relates to a kind of relay, the magnetic latching relay that especially a kind of magnetic confining force is big, operate time is short.
Background technology
Existing magnetic latching relay majority is designed to rotate magnetic structure, and the advantage of this structure is the magnetic circuit balance, and is suitable for the relay ratio of smaller size smaller and smaller power; But its shortcoming is that four working gas gaps are arranged; The yoke of each working gas gap develops with armature and cooperates difficulty bigger, and is the line contact basically when fitting, to having relatively high expectations of part; Be easy to generate leakage field, the magnetic confining force is difficult to do greatly.
The utility model content
The purpose of the utility model is that the magnetic latching relay that a kind of magnetic confining force is big, operate time is short is provided for the deficiency that solves above-mentioned technology.
In order to achieve the above object; A kind of magnetic latching relay that the utility model designed; It mainly comprises pedestal, magnetic circuit system and contact system, and described magnetic circuit system mainly comprises coil, yoke, moving iron core, static iron core and magnet steel, and contact system includes moving contact combination and fixed contact combination; Contact system and magnetic circuit system are installed in the pedestal side by side, connect through pushing piece to be provided with.
In order to have guaranteed that the state of magnetic circuit when coil is not switched on is able to reliable maintenance, be provided with three magnet steel in the described contact system, wherein two magnet steel are sandwiched between coil and the yoke in the yoke both sides, and another places pedestal to be positioned at moving iron core top one side.
The permanent use of magnet steel for ease, described magnet steel is made up of permanent magnetic material.
The resulting magnetic latching relay of the utility model has three magnetic loops in its whole closure state, off-state and transfer process.In two inactive states, use two groups of magnet steel respectively, two groups of magnet steel play independently maintenance effect respectively, and confining force is strong, and state is very stable; Because magnetic structure is a solenoid structure, working gas gap is to be made up of the gap between two planes of dynamic and static iron core, and leakage field is little, and when coil electricity, action is fast, and is clear-cut strong, the state that pauses in the middle of can not occurring.All relatively low to the requirement of part and the requirement of debuging in the production process, magnetic circuit system is realized the effect exempting to transfer easily, and in addition, because the magnetic confining force is big, contact force is big, receives external magnetic field power interference capability, and the ability of anti-momentary excess current is also stronger relatively.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the magnetic circuit system of the utility model.
Embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Embodiment 1:
Like Fig. 1, shown in Figure 2; The magnetic latching relay that present embodiment is described, it mainly comprises pedestal 1, magnetic circuit system and contact system, described magnetic circuit system mainly comprises coil 2, yoke 3, moving iron core 4, static iron core 5 and magnet steel 6; Contact system includes moving contact combination 8 and fixed contact combination 9; Contact system and magnetic circuit system are installed in the pedestal 1 side by side, connect through pushing piece 7 to be provided with, and wherein are provided with three magnet steel 6 in the contact system; Wherein two magnet steel 6 are sandwiched between coil 2 and the yoke 3 in yoke 3 both sides, and another places pedestal 1 to be positioned at moving iron core 4 tops one side.
Method for using: when relay coil 2 applied a voltage signal, the magnetic field force of its generation can be inhaled to static iron core 5 moving iron core 4, and after applying blackout, the magnetic force that is produced by two magnet steel between yoke 3 and the coil 26 keeps its state; When applying opposite voltage signal on the coil 2; The magnetic field force of its generation overcomes the magnetic force of magnet steel 6; To move iron core 4 and push away static iron core 5, moving iron core 4 is inhaled to a magnet steel 6 that is installed on the pedestal 1, behind coil 2 blackouts; Keep its state by this magnet steel 6 again, realize the function of bi-stable, energy efficient.When moving iron core 4 moves, to moving contact combination 8, realize that the closed or disconnection of contact is changed by pushing piece 7 transmitting and converting.
Claims (3)
