Description
Technical field
The utility model relates to a kind of magnetic latching relay, and particularly relating to the high-power of a kind of brand new can automatically reset magnetic latching relay.
Background technology
The magnetic latching relay that various models are arranged in the market, from small-power, power to high-power, have hand-reset also to automatically reset, but not only do not satisfy high-power but also satisfy automatically reset magnetic latching relay.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, dependable performance, not only satisfies high-power but also satisfy automatically reset magnetic latching relay.
The purpose of this utility model is to adopt following technical scheme to realize:
A kind of high-power magnetic latching relay that automatically resets, it comprises magnetic circuit part, contact portion and bobbin, coil, described contact portion includes one group of normally closed static contact spring piece assembly, one group and often opens static contact spring piece assembly, one group of movable contact spring assembly, described magnetic circuit partly comprises armature, iron core, yoke, yoke and magnet steel, wherein normally closed static contact spring piece assembly, often open the static contact spring piece assembly and be arranged on the bobbin, the movable contact spring assembly is arranged on the yoke; Iron core, yoke, yoke and magnet steel are separately positioned on the bobbin, and the end that armature has protruding bud is fixed on the movable contact spring of movable contact spring assembly, and the afterbody of armature contacts with the edge of a knife face of yoke, form a fulcrum.
Described normally closed static contact spring piece assembly and Chang Kai static contact spring piece assembly insert and are fixed on the bobbin.
Described movable contact spring assembly staking is installed on the yoke of relay.
Described iron core and yoke difference riveted and fixed are on bobbin.
Described yoke inserts and is fixed on the bobbin.
Described magnet steel is fixed on the bobbin with epoxy glue.
Described armature by two protruding luxuriant riveted and fixed on it on the movable contact spring of movable contact spring assembly.
The difference of the utility model magnetic latching relay and existing conventional products is the original structural L type yoke as shown in Figure 1, add a magnet steel after cutting away one from root, constitute a new yoke structure, be the described yoke 7 of technique scheme, yoke 6,8 three parts of magnet steel, as shown in Figure 2, also formed a novel magnetic circuit thus.Magnetic structure of the present utility model is different from the L type yoke of original conventional products because the effect of middle magnet steel makes this assembly itself just have magnetic.This magnetic latching relay has effectively reduced the energy consumption of relay coil because coil does not need long-term power supply.
Each part of the utility model magnetic latching relay adopts the riveted joint or the mounting structure of plug-in mounting can form stable, contact and magnetic circuit system reliably respectively.Because armature has only an end to fix, thus just can rotate within the specific limits, thus drive the movable contact spring group that is riveted together with it, reach the purpose of switch current, voltage.
The utility model has been filled up in the magnetic latching relay industry and has not only been satisfied high-power but also satisfy this blank of automatically reset magnetic latching relay, the drive part of particularly powerful relay own will the bigger electric energy of consumption rate, magnetic latching relay of the present utility model is not because coil needs long-term power supply, can effectively reduce the energy consumption of relay coil, the main trend that meets current energy-conserving and environment-protective, also be the energy consumption that a main direction of relay Future Development can effectively reduce relay coil, meet the development trend of current environmental protection and energy saving.

Embodiment
Below in conjunction with drawings and Examples embodiment of the present utility model is further described:
See also Fig. 3, Fig. 4, this magnetic latching relay comprises that one group of normally closed static contact spring piece assembly 1, one group often open the contact portion that static contact spring piece assembly 2, one group of magnetic circuit part that movable contact spring assembly 3 is formed and armature 31, iron core 5, yoke 7, yoke 6 and magnet steel 8 are formed.Coil 10 is installed on the bobbin 9, normally closed static contact spring piece assembly 1 and Chang Kai static contact spring piece assembly 2 adopt the mode of plug-in mounting to be inserted on the bobbin 9 respectively, 3 of movable contact spring assemblies adopt riveted way to be installed on the yoke 7 of relay, and these assemblies adopt the method for plug-in mounting and riveted joint can form stable, reliable contact system.Iron core 5 and yoke 6 adopt riveted way to be fixed on the bobbin 9, yoke 7 adopts the mode of plug-in mounting to be fixed on above the bobbin 9, magnet steel 8 adopts epoxy glue to be fixed on the bobbin 9, on the armature 31 two protruding luxuriant 33 are fixed on the movable contact spring 32 by riveted way, the afterbody 34 of armature 31 contacts with the edge of a knife face 71 of yoke 7 simultaneously, form a fulcrum, as above just formed the magnetic circuit part of this relay after the assembling.Because of having only an end, fixes in armature 31, thus just can be the rotating of certain limit, thus drive the movable contact spring assembly 3 that is riveted together with it, reach the purpose of switch current, voltage.
Fig. 5 to Fig. 7 is respectively the magnetic line of force direction of relay energized relay circuit when no power, logical forward electricity, logical oppositely electricity.As shown in Figure 5, relay is under the reset mode, coil 10 is not being applied under the situation of pulse voltage, because magnet steel 8 effects own have produced a field circuit to the energized relay circuit system, but owing to do not form closed magnetic field, add the effect of movable contact spring 32 counter-forces own, be adsorbed onto 5 iron core end faces 51 and get on so fail an armature 31.
As shown in Figure 6, after giving the direct impulse voltage of 10 1 certain widths of relay coil, relay coil 10 produces a magnetic field, the direction in magnetic field is consistent with the direction of magnet steel 8, the magnetic fields that itself produced by magnet steel 8 on this time iron core end face 51 add magnetic field that coil 10 the produces counter-force greater than movable contact spring 32, armature 31 is adsorbed on the iron core end face 51, and movable contact spring assembly 3 is driven by armature 31 and switches to normally opened contact by normally-closed contact simultaneously.Formed the closed-loop path of a magnetic circuit because armature 31 is closed with iron core end face 51 this time, do not bleed off so armature 31 can remain on normal battle.
As shown in Figure 7, after giving the reverse impulse voltage of 10 1 certain widths of relay coil, relay coil 10 produces a magnetic field, the direction in magnetic field is opposite with the direction of magnet steel 8, the magnetic field that is produced by the magnetic field and the coil 10 of magnet steel 8 itself on this time iron core end face 51 is just in time offset or is subdued, the magnetic field that this time, movable contact spring 32 counter-force produced greater than magnet steel 8 deducts the magnetic field that coil 10 produces, get back to initial position so movable contact spring 32 resets, movable contact spring assembly 3 is also simultaneously by returning to normally closed point normal battle.
