Description
Technical field
The present invention relates to a kind of electromagnetic relay, particularly relate to the electromagnetic relay of a kind of high magnetic efficiency, less foreign substance pollution.
Background technology
Current, along with the raising of living standards of the people, the application of household electrical appliance such as colour TV, air-conditioning, refrigerator, washing machine, water heater, soy bean milk making machine is more prevalent, and the trend of progressively promoting to zones such as samll cities and towns and rural areas is arranged; At developed countries such as North America, West Europe, except above-mentioned general household electrical appliance, high-grade household electrical appliance such as automatic dish-washing machine, electric heat mat, electronic masseur have also stepped into common family basically.
Electromagnetic relay is as the basic controlling assembly of household electrical appliance; Its application market field also constantly enlarges along with the continual renovation of various household electrical appliance; The new demand that client proposes also constantly increases along with the expansion of application, relatively more typically requires to have: miniaturization, low-power consumption, low cost, highly reliable, high capacity or the like.Particularly how to reduce foreign substance pollution, guarantee the cleanliness factor on relay contact surface, some problems such as raising reliability of products are relay manufacturing merchant's difficult points always.
A kind of electromagnetic relay of prior art (is seen the patent No.: 200410048462.7); One end of its armature is directly spacing near the iron core pole-face by base; The other end forms free end and cooperates with push card, and the other end of its push card is established two convexities and cooperated with free-ended two circular holes of corresponding moving spring.Drawbacks such as this design on the one hand, owing to adopt the spacing mobilizable armature of stiff base, makes armature and iron core pole-face not to fit fully, causes the positioning accuracy of armature poor, and magnetic efficiency is low; On the other hand, because mobilizable armature is directly contacted with the base that is injection molded into plastic material, make in the armature activity easily and to consider to be worth doing, caused the drawback of pollution contact, thereby reduced reliability of products with the base plastics that rub out.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; The electromagnetic relay of a kind of high magnetic efficiency, less foreign substance pollution is provided; Through to can be with near the improvement of the structure of the limiting position of armature iron core pole-face; On the one hand, make armature and iron core pole-face to fit fully, to reach the positioning accuracy that improves armature and the purpose of magnetic efficiency; On the other hand, can reduce foreign substance pollution, guarantee the cleanliness factor on relay contact surface, to reach the purpose that improves product reliability.
The technical solution adopted for the present invention to solve the technical problems is: the electromagnetic relay of a kind of high magnetic efficiency, less foreign substance pollution comprises base, magnetic circuit part, contact portion and push card; This magnetic circuit partly comprises drum stand, enamelled wire, U sections core, armature and stage clip; The mid portion of U sections core is embedded in the drum stand, and enamelled wire is wrapped in outside the drum stand that contains U sections core; One end of this armature is provided with Ka Tai; The centre of this stage clip is provided with the flexible tongue that compresses, and the both sides of stage clip are provided with fin; This stage clip is installed on the base through the fin of both sides, and the Ka Tai that tongue elasticity is pressed on armature of compressing of this stage clip sentences an end of armature can be close on the edge of a knife of iron core pole-face.
Have at least one to be provided with the chucking convexity in two fins of described stage clip, on base, be provided with the stage clip slot that is used to install stage clip, stage clip is fixed on the base through protruding the opening in the stage clip slot that withstands on base of the chucking of fin.
The described tongue that compresses is that the middle part of stage clip constitutes to end formed silver after set out two groovings, this silver near a skew back of armature to folding so that it has elasticity.
Have at least the afterbody of a fin to form kink in two fins of described stage clip to armature one lateral buckling, this kink at a distance from the armature that is provided with Ka Tai one end end along between face and the base.
The afterbody of the fin of described stage clip forms kink to the bending of 90 ° of armature one sides, this kink at a distance from the armature that is provided with Ka Tai one end end along between face and the base.
Described drum stand is made up of the extension of base.
The electromagnetic relay of a kind of high magnetic efficiency of the present invention, less foreign substance pollution is to be fixedly movable spring assembly, quiet spring assembly and stage clip of carrier with the base, and this base is provided with the extension that is used for twining enamelled wire and promptly is equivalent to drum stand; And the extension that movable spring assembly, quiet spring assembly and stage clip are mounted to base is on the position of almost parallel; Iron core adopts U type structure, and this U sections core is embedded in the extension of base, and the pole-face at iron core two ends is all towards the direction that movable spring assembly, quiet spring assembly are installed; Enamelled wire is directly to be wrapped on the extension of the base that iron core is housed; Armature is overlayed on the edge of a knife of iron core one end pole-face through the stage clip that is fixed in base; Establish in the centre of stage clip and to compress tongue; End at armature is established Ka Tai; The Ka Tai of tongue through armature that compress of stage clip is pressed in an end of armature on the edge of a knife of iron core pole-face, the other end that makes armature be free end when rotating around armature one end of establishing Ka Tai, the elasticity of establishing armature one end pressurized spring pressing tongue in rotation process of Ka Tai compresses and can not break away from the edge of a knife of iron core pole-face all the time; Promptly can rotate and can not break away from, magnetic efficiency is high; The both sides of stage clip form two fins, have at least one to be provided with the chucking convexity in two fins, and like this, when packing stage clip into base, the chucking in the fin is protruding to match with the stage clip slot of base, makes stage clip tighten and to be fixed on the base; The afterbody of the fin of stage clip both sides is bended; Promptly form kink to armature one lateral buckling; This kink just be in be provided with Ka Tai armature one end end along between face and the base, play buffer action, be equivalent to be provided with isolating bar; Isolated the metal armature afterbody and contacted with the direct of plastic feet, the plastics bits that effectively prevent to rub out etc. pollute foreign matter.The other end of armature is that free end then cooperates with an end of push card; The push card other end then matches with movable spring assembly; Like this; Can the activity of armature be passed to movable spring assembly through push card, the contact between the contact of realizing movable spring assembly and the contact of quiet spring assembly or separate promptly realizes the connection of relay contact and the switching function of branch deenergizing.
