Abstract
The utility model discloses a kind of A.C. contactor with symmetrical iron core group, the fixed support comprising base and assemble with base, coil groups is equipped with at base built with yoke, at fixed support built with movable support and armature, yoke, be equipped with between yoke and armature and return spring, the symmetrical shape of yoke and armature, has one end to rivet respectively and has short-circuited conducting sleeve, fixed support is equipped with fixed contact, movable support is equipped with moving contact, movable support is equipped with touch spring.Iron core group of the present utility model adopts the design that yoke is identical with armature, yoke and armature distinguishes riveting short-circuited conducting sleeve, is composed of iron core group, can saves the input of mould under the prerequisite meeting product function, improve the production efficiency of product, reduce the cost.
Description
Technical field
The utility model relates to A.C. contactor, particularly relates to a kind of A.C. contactor with symmetrical iron core group.
Background technology
The circuit that A.C. contactor controls is alternating current, the effect of short-circuited conducting sleeve is that the iron core pole-face in A.C. contactor is divided into two parts, iron core is made to produce two kinds of nonsynchronous magnetic fields, produce magnetic hysteresis, still have magnetic field when alternating current zero passage, maintain between sound iron core and there is certain suction, to remove the vibration between dynamic and static iron core, so just can keep the adhesive of iron core always, would not shake along with the change of electric current.If there is no short-circuited conducting sleeve, A.C. contactor can along with electric current change and ceaselessly shake, produce noise simultaneously.
In conventional AC contactor two short-circuited conducting sleeves of iron core be all riveting on yoke, form iron core group with armature, then form the electromagnetic system of A.C. contactor with coil groups.Owing to yoke needing riveting short-circuited conducting sleeve, without the need to riveting short-circuited conducting sleeve on armature, therefore yoke is different with the structure of armature, needs to amass into mould for yoke and armature make two secondary different high speeds in production, and mould has high input, and production cost is high, and production efficiency is low.
Utility model content
The utility model aims to provide a kind of A.C. contactor with symmetrical iron core group, realizes the input of saving mould under the prerequisite meeting product function, improves the production efficiency of product, reduces the cost.
The technical solution of the utility model is as follows:
A kind of A.C. contactor with symmetrical iron core group, the fixed support comprising base and assemble with base, coil groups is equipped with at base built with yoke, at fixed support built with movable support and armature, yoke, be equipped with between yoke and armature and return spring, the symmetrical shape of yoke and armature, has one end to rivet respectively and has short-circuited conducting sleeve, fixed support is equipped with fixed contact, movable support is equipped with moving contact, movable support is equipped with touch spring.
Advantageous Effects of the present utility model is:
Iron core group of the present utility model adopts the design that yoke is identical with armature, is all amassed into by the lamination of equal number.Yoke and armature distinguish riveting short-circuited conducting sleeve, and yoke and armature are composed of iron core group.When coil groups is energized, armature is inhaled.The suction of electromagnetic system overcomes the reaction force returning spring and touch spring, and moving contact and fixed contact are connected, and main circuit is connected.Again owing to there being the effect of short-circuited conducting sleeve, when current over-zero, have induced current in short-circuited conducting sleeve, can stop this part changes of magnetic field, thus magnetic force is stablized, A.C. contactor can normally work.Because yoke and armature are designed to the same, the input of mould can be saved under the prerequisite meeting product function, improve the production efficiency of product, reduce the cost.
Accompanying drawing explanation
Fig. 1 is front sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, the utility model fixed support 6 of comprising base 1 and assembling with base 1.At base 1 built with yoke 2, at fixed support 6 built with movable support 11 and armature 10.Yoke 2 is equipped with coil groups 3, is equipped with between yoke 2 and armature 10 and returns spring 5.The shape of yoke 2 and armature 10 is rotational symmetric, is all E type, and on one end of E type, riveted joint has short-circuited conducting sleeve 4 respectively.In FIG, the short-circuited conducting sleeve 4 in left side is riveted on armature 10, and the short-circuited conducting sleeve 4 on right side is riveted on yoke 2.Fixed support 6 is equipped with fixed contact 9, movable support 11 is equipped with moving contact 8, movable support 11 is equipped with touch spring 7.
After coil groups 3 is energized, armature 10 is dynamic by suction, and the suction of electromagnetic system overcomes the reaction force returning spring 5 and touch spring 7, and moving contact 8 and fixed contact 9 are connected, and main circuit is connected.When coil groups 3 power-off, armature 10 and moving contact 8 move under the reaction force acts returning spring 5 and touch spring 7, and contact disconnects and produces electric arc, and electric arc is under the driving of contact loop electric power and aerodynamic force, in arc control device, be subject to strong cooling go free and extinguish, main circuit final cutting.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection range of the present utility model.
