Description
Technical field
The utility model is related to a kind of relay, more particularly to a kind of relay iron structure.
Background technology
Electromagnetic relay is a kind of to be gone to control larger electric current, higher voltage with less electric current, relatively low voltage
Automatic switch.It realizes that this switching function is by the coil for being arranged inside, by being passed through smaller current to coil so that
Coil produces magnetic field, and adhesive or armature is unclamped using the generation or disappearance in magnetic field, so drive between electroconductive elastic sheet adhesive or
Disconnect, realize the conducting to big current loop.However, because the volume of existing electromagnetic relay is very small, therefore, coil
Volume is also very small, and armature is located at one end of the outside of coil, and the magnetic flux of coil is less, and this allows for the magnetic produced by coil
Suction is very small, causes the adhesive effect of relay poor, influences the stability of electromagnetic relay.
Utility model content
The purpose of this utility model is that providing one kind makes flux concentrating in centre, to strengthen coil magnetic field, improves adhesive
The relay iron structure of power.
To achieve these goals, the relay iron structure that the utility model is provided includes coil, secured core and can
Dynamic iron core, the middle part of the coil has iron core hole, and the secured core is fixed on the one end in the iron core hole, the movable iron
Core is slidingly arranged at the other end in the iron core hole, the inner and secured core of the movable core it is inner corresponding,
Described in the coil adhesive during movable core, the movable core is moved to the secured core, and the movable core
Inner end face is matchingly fitted with the inner end face of the secured core.
Because the utility model is by the way that the secured core and movable core are arranged in the iron core hole, so that in institute
When stating movable core described in coil adhesive, the end face of the movable core is set matchingly to be pasted with the end face of the secured core
Close, the structure is conducive to flux concentrating in centre, to strengthen the magnetic field of coil, improves the suction-combining force, improves the stabilization of relay
Property.
It is preferred that the inner end face of the movable core is convex portion, the inner end face of the secured core is in and institute
State the recess of convex portion cooperation.
It is preferred that the inner end face of the movable core is plane, V-arrangement face, step surface or arcwall face.
It is preferred that being provided with coil brace between the coil and the secured core and the movable core.

Embodiment
To describe technology contents of the present utility model, construction feature, the effect realized in detail, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
As shown in Figure 1, Figure 2 and Figure 3, the embodiment one of the utility model relay iron structure 100 is illustrated in figure
Structure, it includes coil 1, secured core 2 and movable core 3, and the middle part of the coil 1 has iron core hole 11, the fixed iron
Core 2 is fixed on the one end in the iron core hole 11, and the movable core 3 is slidingly arranged at the other end in the iron core hole 11, institute
State the inner inner corresponding with the secured core 2 of movable core 3, the coil 1 and the secured core 2 and described movable
Coil brace 4 is provided between iron core 3；Described in the adhesive of coil 1 during movable core 3, the movable core 3 is to the fixed iron
Core 2 is moved, and inner end face 31 and the secured core 2 of the movable core 3 inner end face 21 matchingly
Laminating.Specifically, the inner end face 32 of the movable core 3 be convex portion and V-shaped face, the secured core 2 it is inner
End face 21 is in the recess and V-shaped face coordinated with the convex portion.
As shown in figure 4, illustrated in figure the embodiment two of the utility model relay iron structure secured core 2 and can
The structure of dynamic iron core 3, the structure with above-described embodiment one is essentially identical, and difference is, the inner end of the movable core 3
Face 32 is plane, and the inner end face 22 of the secured core 2 is in putting down that the inner end face 32 with the movable core 3 coordinates
Face.
As shown in figure 5, illustrated in figure the embodiment three of the utility model relay iron structure secured core 2 and can
The structure of dynamic iron core 3, its structure with above-described embodiment one is essentially identical, and difference is, the movable core 3 it is inner
End face 33 is convex portion and is prominent step surface, and the inner end face 23 of the secured core 2 is in recessed with convex portion cooperation
Portion and the step surface to sink.In addition, the inner end face of the movable core 3 can also be arcwall face, the secured core
Inner end face then be corresponding arcwall face.
Because the utility model is by the way that the secured core 2 and movable core 3 are arranged in the iron core hole 11, so that
In movable core 3 described in the adhesive of coil 1, make the end face of the movable core 3 and the end face phase of the secured core
With ground laminating, the structure is conducive to flux concentrating in centre, to strengthen the magnetic field of coil 1, improves the suction-combining force, improves relay
Stability.
Above disclosed is only preferred embodiments of the present utility model, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to present utility model application the scope of the claims still fall within the utility model and are covered
Scope.
