Description
Technical field
The utility model belongs to the connector with induction coupling, and existing movable core, coil or winding are made the technical field that noncontact connects, and are specifically related to a kind of electromagnetic core that embeds magnet.
Background technology
Present AC and DC electromagnetic contactor of using and electromagnetically operated valve etc., what used electromagnet great majority adopted is E type clapper-type structure.Its attracting state relies on to the solenoid continued power, utilizes electromagnetic attraction to make the position that iron core remains on to be needed.On coil the electric current of confession lose, spring force makes it be discharged into reset mode.Especially alternating electromagnet, for avoiding the suction forfeiture of electromagnet when the alternating voltage zero-crossing, existing solution to this problem is to inlay one group " short-circuited conducting sleeve " on adhesive face, but still can not abate the noise fully.Someone once used elements such as electric capacity, inductance, diode to abate the noise, and all tackled the problem at its root because of failing, and there is no remarkable energy saving effect and can not popularize.Produce the eddy current iron loss in order to reduce alternating electromagnet, its iron core preferably adopts silicon steel sheet to laminate shaping, and production cost is far higher than the mild steel that DC electromagnet adopts.In addition,,,, unavoidably produce Joule heat, also can burn coil when serious owing to must give the coil continued power in its operating state no matter be alternating electromagnet or DC electromagnet.Under the normal condition, with regard to the consumption of product, electromagnet is inestimable to the consumption of electric energy.As an electromagnetic contactor through the rated current 50A of International Power tissue authentication, its coil loss is 17VA in working order, and thermal losses is 5.5W.
For addressing the above problem, many people design, but still have not all roses part, as the patent No. is the Chinese patent of ZL00204601.6, the design of magnetic circuit failed to solve simultaneously avoid magnet to bear impact force, utilize magnet magnetic energy and production technology simple question efficiently, and be unfavorable for industrialization.
Summary of the invention
Technical problem underlying to be solved in the utility model and solve the technical scheme that its technical problem adopts and be: on mounting panel, establish by left pole shoe, middle pole shoe, the fixed core that right pole shoe constitutes, in fixed core, be provided with coil, on fixed core, be provided with moving iron core, in moving iron core, be provided with back-moving spring, between left pole shoe and middle pole shoe, be provided with left magnet, between middle pole shoe and right pole shoe, be provided with right magnet, the extreme face of S and the left pole shoe of left side magnet link, extreme face of N and middle pole shoe link, and extreme face of the S of right magnet and right pole shoe link, extreme face of N and middle pole shoe link.
Left magnet of the present utility model and right magnet also can be arranged on moving iron core.
Left magnet of the present utility model and the also available polylith magnet of right magnet serial or parallel connection combine.
Left magnet of the present utility model and right magnet are made with rareearth magnetic material.
Rareearth magnetic material of the present utility model is a NdFeB material.
The utility model embeds two blocks of magnet respectively in the bottom at two matrix positions of iron core, and same polarity is relative, and the both wings of iron core are the same sex, and the center is the opposite sex.After electromagnetic force makes it closure, the square shape magnetic loop that forms two closures can make, the tight adhesive of fixed core, on the coil the electric current of confession can disconnect, can utilize magnetic energy long-term effectively, obtain the magnetic force sticking, only need energy-conservation, the muting effect of electromagnetic force effect in moment.It has reasonable in design, advantages such as production cost is low, energy-conservation, noiseless, manufacture method are simple, working stability, little power consumption, can be used for Electromagnetic Control elements such as electromagnetic contactor, electromagnetic brake, electromagnetically operated valve.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited to these embodiment.
In Fig. 1, present embodiment is made of moving iron core 1, coil 2, right pole shoe 3, right magnet 4, middle pole shoe 5, left magnet 6, left pole shoe 7, mounting panel 8, back-moving spring 9 connections.
On mounting panel 8, be installed with left pole shoe 7, middle pole shoe 5, right pole shoe 3, left side pole shoe 7 and right pole shoe 3 are S utmost point pole shoe, middle pole shoe 5 is a N utmost point pole shoe, mounting panel 8 is a non-magnet material, left side pole shoe 7, middle pole shoe 5, right pole shoe 3 usefulness soft magnetic materials are made, also can make with low-carbon steel material, left magnet 6 is installed between left pole shoe 7 and middle pole shoe 5, the extreme face of S of left side magnet 6 and left pole shoe 7 stick with glue and connect, extreme face of N and middle pole shoe 5 stick with glue and connect, right magnet 4 is installed between middle pole shoe 5 and right pole shoe 3, the extreme face of S of right magnet 4 and right pole shoe 3 stick with glue and connect, extreme face of N and middle pole shoe 5 stick with glue and connect, and left magnet 6 and right magnet 4 usefulness NdFeB materials are made.The left magnet 6 of present embodiment and the also available polylith magnet of right magnet 4 serial or parallel connection combine.Left side pole shoe 7, middle pole shoe 5, right pole shoe 3 are connected into E shape fixed core, in E type fixed core coil 2 are installed.Moving iron core 1 is placed on the E type fixed core, and moving iron core 1 also is an E shape, and moving iron core 1 can vertically move up and down, and on moving iron core 1 back-moving spring 9 is installed.The left magnet 6 of present embodiment and right magnet 4 also can be installed in moving iron core 1.When DC Forward Current being provided for coil 2, be that the sense of current should make the pole orientation of coil generation identical with the direction of embedded magnet magnetic pole, moving iron core 1 can vertically move down, E type fixed core and moving iron core 1 moment by adhesive, after this, can cut off the power supply, at this moment be combined to form the flux loop of the closure of two " square shapes " by fixed core and moving iron core 1, both are promptly by firm adhesive.When reverse dc being provided for coil 2, promptly the sense of current should make the pole orientation of coil generation opposite with the direction of embedded magnet magnetic pole, and electromagnetic force makes the suction of magnet weakened, under the effect of back-moving spring 9 elastic force, and moving iron core 1 return.
