Abstract
The utility model discloses a permanent magnetism double-coil stable state powerless relay contactor which comprises a fixing bole, a lower yoke magnetic pole plate, upper and lower coils, a magnetic flux pole plate, a magnet, a magnetic flux bridge piece, a coil framework, a coil copper wire, an armature iron, and an armored type magnetic flux frame. The magnet is connected with the magnetic flux bridge piece at the middle of the upper and the lower coils, the magnetic flux pole plate is connected with the magnet, and the armored type magnetic flux frame is connected with the magnetic flux pole plate. The utility model can effectively overcome the disadvantages existing in the current relays that the elevation of temperature is quick, the power consumption is large, the noise is large, and the volume is large.
Description
The utility model relates to a kind ofly does magnetic energy conversion by the permanent magnet twin coil, utilizes pulse-triggered, and what middle armature was stable is locked in up and down or left and right sides two-stage, realizes driving the contact, and contact does not have the power consumption relay contactor as a kind of permanent magnetism twin coil bistable state of switch.It can directly apply in the production field of micro electromagnetic relay and serial alternating current contactor.
At present, to be widely used in electronic equipment and the power equipment be that automatic control switch uses for traditional electromagnetic relay and A.C. contactor.Especially the CJ A.C. contactor is used for single-phasely, during the threephase motor control loop, is a kind of safe in utilization, control control far away easily and autocontrol switch.But the CJ A.C. contactor is in routine is used, because operating current is big during operation, 91.5% energy loss of total power consumption is on magnetic hysteresis, eddy current and short-circuited conducting sleeve, the meritorious power consumption major part of coil becomes heat and loses, especially the CJ ac contactor coil of 5A-40A because the number of turn is many, line through carefully, weak heat-dissipating, easy firing.In addition, sticking and startup instability, vibration greatly, easily make contact produce electric arc.Time has been grown ablated, causes three phase electric machine to be burnt because of phase shortage thereupon.And general miniature electro-magnetic relay is also little because of volume, and flexibility is strong, in household electrical appliance and numerous electronic product, does the relay conversion and has made immeasurable contribution.But miniature electro-magnetic relay, also little because of volume, poor radiation are decided because of its power, do not realize that small-power drives the feasibility of big contact, also especially forced use under the environment of radiating condition difference in various fields.
The purpose of this utility model is not have the power consumption relay contactor by designing a kind of permanent magnetism twin coil bistable state, drawbacks such as it can overcome effectively that the temperature rise that exists in the present relay is fast, power consumption is big, noise is big, the big contact of the large and small power band of volume and the adhesion of electric shock contact reach energy-saving convenient to adapt to the big needs of producing of modernization.
The purpose of this utility model be achieved in that design a kind of by fixing screw, down yoke magnetic pole version, up and down or the permanent magnetism twin coil bistable state formed such as left and right sides coil, magnetic flux pole plate, magnet, magnetic flux gap bridge, coil rack, coil copper cash, armature, armoured type flux frame do not have the power consumption relay contactor.
Magnet is passed a bridge with magnetic flux and is connected, be positioned at up and down or the middle part of left and right sides coil, the magnetic flux pole plate is connected on the magnet, the coil copper cash is wrapped on the coil rack and contacts with the armature that is moving, being equipped with in two hub of a spool skeletons can be up and down or the permeability magnetic material armature of move left and right, following yoke magnetic pole plate is installed in the bottom, rely on fixing screw to locate, armoured type magnetic flux pole plate is connected with flux frame, the cooperation position of the coil of putting and magnet, vertical magnet is skeleton intersection in the middle of two coils up and down, and moves up and down in the chute of armature between last lower coil and the cooperation of middle magnet.The horizontal cooperation with it with middle magnet by left and right sides coil formed magnetic loop, establishes magnet between left coil and the right coil and produces the N.S two-stage, utilizes the pure iron conduction, and the armature that makes it can attract respectively to move drives the contact.
The utility model comes from the bistable state locking principle, adopts a magnetic two-pass design, produces strong magnetic energy by two parts coil up and down.Produce magnetization by armoring packaging type magnetic circuit, constituted two relatively independent Ji Cinengyuan.When one of them coil was received pulse voltage, this coil produced high-energy magnetic field, made center armature magnetization, made the part of this coil constitute the magnetic saturation loop fully.Meanwhile armature can only move to the end that electricity is arranged, and produces holding course.But after the pulse voltage, armature is very strong permeability magnetic material, makes this section generation magnetic loop and attracts each other by self conduction, so can only be locked in this end.In like manner, another coil of next cycle gets electric, and armature is magnetized sticking to the other end.The motion that goes round and begins again forms stable bistable state, drives the process that contact point realizes dynamo-electric conversion.The solenoid power-on time only needs 0.3 second, and moment just can produce huge energy.Armature is inhaled, is scolded speed fast, and explosive force is strong.Do not need electric energy to keep during the normal sticking of armature, this point is the basic place of economize on electricity.
In the generation of utility model circuit pulse, can there be two kinds of forms to generate.A kind of for electronic circuit produces, first cycle is kept supplying portion's coil for direct impulse voltage and uses, and second period is that negative pulse voltage uses for lower coil, makes it armature and produces suction or hold the overall process of scolding.Another kind of form is the self-locking commutation process, and the moment armature sticking of switching on exactly drives linked switch simultaneously and makes it commutation, the connection direction of transfer stitch, and connect another wire loop simultaneously, wait for and scold out armature to electricity next time.
Owing to adopt such scheme, it can effectively overcome and has drawbacks such as temperature rise is fast, power consumption is big, noise is big, volume is big in the present relay, and test shows that power saving rate reaches more than 99.98%.
