Description
Technical field
The present invention relates to the contactor field, in particular to A.C. contactor, relate in particular to the contactor with 7 to 15 amperes of rated operational currents.
Background technology
A.C. contactor is widely used in for example break-make of motor of power equipment, it is usually mainly by the contactor housing, comprise coil, the electromagnetic mechanism of static iron core and moving iron core (armature) and contact unit (comprising main contact unit and the optional auxiliary contact unit of establishing) and some other parts known in the art or structure (arc extinguishing structure for example, antagonistic spring and contact pressure spring etc.) consist of, its basic functional principle is to pass through coil electricity, thereby produce electromagnetic attraction between static iron core and armature, the spring force that makes thus armature overcome antagonistic spring is attracted near and finally contacts static iron core, thereby the contact unit of contactor engages, perhaps opposite.
In existing design, the design communication contactor has the width of the multiple of 9mm usually, is typically, and the contactor of existing 38A and following amperage all has 45mm left and right or larger width basically.Can provide good applicability although usually have these contactors of 45mm width, it has obvious shortcoming, for example takes up an area the space excessive, and especially width is excessive, and this is very undesirable to more existing very compact installation occasion.To this, the inventor reverses existing custom and overcomes the multiple technologies difficulty, is desirable to provide a kind of width less than the contactor with 7 to 15 amperes of rated operational currents of 45mm, and such contactor has the advantages such as the installing space of saving, appearance looks elegant.
Summary of the invention
For this reason, the invention provides a kind of contactor with 7 to 15 amperes of rated operational currents, comprising: the contactor housing; Be accommodated in the electromagnetic mechanism in this contactor housing, this electromagnetic mechanism has coil, static iron core and is positioned at top and the vertical isolated moving iron core of this static iron core; Contact unit with moving contact and fixed contact, wherein this moving contact is configured to this moving iron core interlock in order to correspondingly engage or break away from this fixed contact with the motion of this moving iron core, wherein, should moving iron core with the vertical interval between this static iron core namely open distance for≤3.5mm and 〉=2mm, and should move the height of iron core less than the height of this static iron core.
By setting of the present invention, except the effect that the acquisition width significantly reduces, also have many other advantages according to the little amperage rated operational current contactors of 7 to 15 amperes of the present invention.
In the prior art, the impulsive force when people can wish to reduce the adhesive of sound iron core usually also wishes to have higher stability simultaneously in moving iron core attracting process.The impulsive force that produces when reducing adhesive is iron core weight to be compared as far as possible with static iron core weight reduce according to an important means of prior art.And in order to have higher adhesive stability in attracting process, an important way is in the situation that other conditions permit improves the electromagnetic attraction of electromagnetic mechanism as far as possible.now, research and propose, for the many factors of sound iron core, the aspect ratio of sound iron core has the greatest impact for electromagnetic attraction, if sound iron core aspect ratio is less, electromagnetic attraction reduces manyly, and when sound iron core height is 1: 1 substantially, in the situation that other condition is constant, this electromagnetic mechanism has approached maximum for the utilization of magnetic flux, it is maximum that thereby electromagnetic attraction also approaches, and along with sound iron core aspect ratio further increases, electromagnetic attraction can not enlarge markedly (than the increase when following 1 of sound iron core aspect ratio) again, even may reduce.In addition, more existing researchs also show, along with the weight increase of moving iron core, also can cause electromagnetic attraction to increase, but its impact on electromagnetic attraction will be significantly less than aspect ratios.
In addition, it will be apparent to those skilled in the art that in the situation that other factors is constant, along with the increase of opening distance, electromagnetic attraction can corresponding reducing.Therefore, in the prior art for as far as possible impulsive force and stable aspect obtain preferably compromise, especially in the contactor with 7 to 15 amperes of rated operational currents of the present invention, common way is, substantially be 1: 1 o'clock (even the aspect ratio of sound iron core is larger) sound iron core aspect ratio is kept, reduce as far as possible moving iron core weight, such as form otch or cut portion etc. in moving iron core, and usually set its sound iron core open distance usually greater than 5mm, it is more common that to open distance be in the scope of 6mm-7mm.
The inventor unexpectedly finds, if open distance greater than about 3.5mm, for the little electromagnetic mechanism of moving iron core aspect ratio static iron core height, electromagnetic attraction can sharply reduce, aspect ratio is roughly the electromagnetic mechanism of 1: 1, this situation do not occur, perhaps this in confused situation aobvious; And if open distance≤about 3.5mm, the electromagnetic system that above-mentioned aspect ratio is little is roughly 1: 1 than above-mentioned aspect ratio can be little too many with regard to electromagnetic attraction.
To this, the present invention sets and opens distance≤approximately 3.5mm and moving iron core height less than the static iron core height between this moving iron core and this static iron core, for example its aspect ratio is less than approximately 0.9, thus, can be in the situation that routine work environment (for example non-heavily loaded environment) and providing satisfactory rated operational current to produce gratifying adhesive stability, can also significantly alleviate simultaneously moving iron core weight, thereby advantageously reduce the adhesive impulsive force, increase the service life.In addition, owing to opening significantly reducing of distance, the electromagnetic system of contactor of the present invention can have less cross-sectional area, thereby can take narrower width.In addition, because moving iron core weight significantly reduces than prior art, so can make the dimension reduction of the Various Components that comprises the reaction force spring, even under the electromagnetic attraction that reduces (for example below about 6N, prior art is typically about 8-11N), good adhesive stability and the adhesive action of accelerating still can be provided, be conducive to reduce adhesive and impact, and be conducive to heat radiation.
Need to further illustrate at this, moving iron core height is applicable to have the A.C. contactor of the little ampere rated operational current of 7-15 ampere in conjunction with the above-mentioned setting means of opening distance and further feature of the present invention less than the static iron core height.And for more large-scale A.C. contactor, the A.C. contactor of 18-40 ampere for example, such setting is usually not too applicable, and its reason may be, because its amperage is larger, in order to guarantee safe and stable operation, need the minimum of relative set to open apart from also larger, usually must be greater than 4.5mm, even more than 6mm, if open at this and stipulate again under distance that moving iron core height less than the static iron core height, may bring the problem of electromagnetic attraction excessive attenuation as described above.
In addition, as preferred version of the present invention, the ratio that the inventor has set moving iron core height and static iron core height meticulously about 0.4 to about 0.6 scope, more preferably approximately 11/20.By setting like this, can more advantageously realize the contactor that width reduces, and contactor also have good, satisfactory at least performance.Aspect ratio preferably should be not too small, in order to avoid cause the required electromagnetic attraction that provides excessively to reduce, thereby system can not work, perhaps for needed electromagnetic attraction is provided, opens distance and will choose very littlely, may affect the effect that dynamic/static contact is broken electric arc.Above-mentioned aspect ratio is preferably not excessive yet, otherwise for the DeGrain that reduces the impact aspect.
