Abstract
The utility model discloses a kind of relay iron structure, be suitable for the armature of attracting electric relay, it comprises the U-shaped iron core with two iron props, described U-shaped iron core is in being horizontally disposed with, be positioned at the described iron prop winding around of downside, the end of described iron prop being positioned at upside upwards bends and extends adhesive portion, described adhesive portion and described armature just right.It is effective that the utility model relay iron structure has adhesive, the advantage of long service life.
Description
Technical field
The utility model relates to a kind of relay, particularly relates to a kind of adhesive effective, the relay iron structure of long service life.
Background technology
Electromagnetic relay is the electric current that a kind of use is less, lower voltage removes the automatic switch controlling larger electric current, higher voltage.It realizes this switching function is by being arranged at inner electromagnet, by passing into small electric stream to magnet spool, electromagnet is made to produce magnetic field, utilize the generation in magnetic field or disappearance and adhesive or unclamp armature, and then order about adhesive or disconnection between electroconductive elastic sheet, realize the conducting to big current loop.Electromagnet is the important composition parts of electromagnetic relay.But, because the volume of existing electromagnetic relay is very little, therefore, the volume of electromagnet is also very little, and this magnetic attraction just making electromagnet produce is very little, and in order to energy open circuit smoothly, the resilience force of the shell fragment of relay is larger again, when magnetic attraction and resilience force are more or less the same, will cause the adhesive weak effect of relay, affect the performance of electromagnetic relay, the useful life of electromagnetic relay is shortened.
Utility model content
It is effective that the purpose of this utility model is to provide a kind of adhesive, the relay iron structure of long service life.
To achieve these goals, the relay iron structure that the utility model provides is suitable for the armature of attracting electric relay, it comprises the U-shaped iron core with two iron props, described U-shaped iron core is in being horizontally disposed with, be positioned at the described iron prop winding around of downside, the end of described iron prop being positioned at upside upwards bends and extends adhesive portion, described adhesive portion and described armature just right.
Compared with prior art, because the utility model is by arranging U-shaped iron core, make the wherein iron prop winding around described in of described U-shaped iron core, iron prop described in another upwards bends and extends an adhesive portion, and make described adhesive portion and described armature just right, therefore, described coil electricity is utilized to produce magnetic field, thus utilize magnetic field adhesive armature, and described adhesive portion can increase the adhesive area of U-shaped iron core on the one hand, when the shock with armature, dynamics of can bearing is larger, number of times more clashes into, the magnetic field of whole U-shaped iron core can be made stronger on the other hand, magnetic attraction is larger, thus easier adhesive armature, adhesive better effects if, effectively increase the service life.
Preferably, described adhesive portion extends to the level height on the top of described armature.By extending the height in described adhesive portion, the adhesive area of described adhesive portion and described armature being increased, thus can magnetic field be increased, improve adhesive effect.
Preferably, the surface being positioned at the described iron prop of upside is provided with convex, and described convex engages with the location hole of the holder of described relay.Coordinating with location hole by arranging described convex, described U-shaped iron core can be made to install more firm, prevent from occurring because of the frequent shock of described armature to loosen or displacement, affect the performance of relay.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model relay iron structure.
Fig. 2 is the schematic diagram of the utility model relay iron structure installment on relay.
Embodiment
For describing technology contents of the present utility model, structural feature, the effect that realizes in detail, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
As shown in Figure 1 and Figure 2, the utility model relay iron structure 100 is suitable for the armature 201 of attracting electric relay 200, it comprises the U-shaped iron core 1 with two iron props 11,12, described U-shaped iron core 1 is in being horizontally disposed with, the cross section of described iron prop 11,12 is square, be positioned at described iron prop 11 winding around of downside, the width being positioned at the described iron prop 12 of upside is increase step by step along bearing of trend, and the end of described iron prop 12 being positioned at upside upwards bends and extends adhesive portion 13, described adhesive portion 13 is just right with described armature 201.Described adhesive portion 13 extends to the level height on the top of described armature 201.By extending the height in described adhesive portion 13, described adhesive portion 13 being increased with the area in the adhesive face of described armature 201, thus can magnetic field be increased, improving adhesive effect.
As shown in Figure 1 and Figure 2, the surface being positioned at the described iron prop 12 of upside is provided with convex 14, and described convex 14 engages with the location hole 203 of the holder 202 of described relay 200.Coordinating with location hole 203 by arranging described convex 14, described U-shaped iron core 1 can be made to install more firm, prevent from occurring because of the frequent shock of described armature 201 to loosen or displacement, affect the performance of relay 200.
Compared with prior art, because the utility model is by arranging U-shaped iron core 1, make wherein iron prop 11 winding around described in of described U-shaped iron core 1, iron prop 12 described in another upwards bends and extends an adhesive portion 13, and make described adhesive portion 13 just right with described armature 201, therefore, described coil electricity is utilized to produce magnetic field, thus utilize magnetic field adhesive armature, and aspect, described adhesive portion 13 1 can increase the adhesive area of described U-shaped iron core 1, when the shock with armature 201, dynamics of can bearing is larger, number of times more clashes into, the magnetic field of whole U-shaped iron core 1 can be made stronger on the other hand, magnetic attraction is larger, thus easier adhesive armature 201, adhesive better effects if, effectively increase the service life.
Above disclosedly be only preferred embodiments of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
