Movable contact spring 6 is fixed on pedestal 2, and armature 8 drives movable contact spring 6 mobile via push jack 5, and movable contact 41 contradicts movable contact spring 6 by push jack 5
It is engaged with the formation of stationary contact 42.The magnetic force that 3 electromagnetic induction of iron core generates attracts armature 8 mobile, and driving pushes away when armature 8 is mobile
Piece 5 is mobile, and driving movable contact spring 6 is mobile when push jack 5 is mobile, and the movement of movable contact spring 6 makes movable contact 41 contact stationary contact 42, to reach
The conducting of circuit.
Movable contact spring 6 is in long strip, and stationary contact 42 is located at the one end of movable contact spring 6 far from pedestal 2, and movable contact spring can be improved in this way
6 suppleness is easier to deform when push jack 5 being made to contact movable contact spring 6, and stationary contact 42 is located at the one end of movable contact spring 6 far from pedestal 2,
The stroke of movable contact 41 is increased, so that movable contact 41 is contacted stationary contact 42 sensitiveer.
Preferably, push jack 5 is equipped with positioning column 53 close to one end of movable contact spring 6, and movable contact spring 6 is equipped with location hole 61, positioning
Column 53 and location hole 61 are mating, can be defined to the relative position of push jack 5 and movable contact spring 6, avoid push jack 5 and dynamic spring
Piece 6 occurs to deviate relatively, influences the normal work of relay.
Preferably, push jack 5 is equipped with reseting leaf 52, and reseting leaf 52 is installed at the hinge joint of push jack 5, for driving
Push jack 5 resets, when reseting leaf 52 in the raw when, buffer stopper 51 is mutually de- close to the end face of movable contact spring 6 and movable contact spring 6
From after coil 31 powers off, push jack 5 can be under the action of reseting leaf 52 far from movable contact spring 6, and then push jack 5 pushes armature 8 de-
From iron core 3.
6 high vibration of movable contact spring is caused in order to avoid push jack 5 contradicts movable contact spring 6, causes contact contact unstable or touching
Point damage, push jack 5 are equipped with the buffer stopper 51 for reducing the vibration of movable contact spring 6 close to one end of movable contact spring 6, when the conflict of push jack 5 is dynamic
When reed 6 is so that movable contact 41 contacts stationary contact 42, buffer stopper 51 is abutted close to the end face of movable contact spring 6 with movable contact spring 6.Buffer stopper
51 close to the end face of movable contact spring 6 be inclined-plane, inclined-plane from push jack 5 towards far from 6 direction of movable contact spring and towards close to armature 8 direction extend
It forms, when movable contact spring 6 is contacted with buffer stopper 51, inclined-plane is more preferably good for the buffering effect of movable contact spring 6, can further subtract
The vibration of small movable contact spring 6.
Pedestal 2 is equipped with the fixed plate 7 for fixing stationary contact 42, offers strip-shaped hole 71, strip-shaped hole 71 in fixed plate 7
Setting can increase the toughness of fixed plate 7, when movable contact 41 contacts stationary contact 42, elastic deformation can occur for fixed plate 7,
There is a buffering to movable contact spring 6, avoids contacting firmly between movable contact 41 and stationary contact 42, cause movable contact 41 or quiet
Contact 42 is damaged, so that movable contact 41 and the contact of stationary contact 42 are more stable.
Preferably, fixed plate 7 is equipped with the bending part for improving 7 ability of anti-deformation of fixed plate far from one end of stationary contact 42

When electric, for push jack 5 not when contradicting movable contact spring 6, fixed plate 7 can apply an elastic force to movable contact spring 6, and it is multiple to facilitate movable contact 41
Position.
Embodiment two:
A kind of relay, as shown in figure 4, the present embodiment and embodiment one the difference is that: buffer stopper 51 is close to dynamic
The end face of reed 6 is in towards the arc surface close to the protrusion of movable contact spring 6, and when movable contact spring 6 and buffer stopper 51 contact, arc surface is to moving
The buffering effect of reed 6 is more preferably good, can further decrease the vibration of movable contact spring 6.
The rest part of the present embodiment is the same as example 1, in the present embodiment unaccounted feature, is all made of implementation
The explanation of example one, is not discussed here.
All technical characteristics in the present embodiment can be freely combined according to actual needs.
In summary: the relay uses to be equipped in push jack 5 close to one end of movable contact spring 6 to be vibrated for reducing movable contact spring 6
Buffer stopper 51, when push jack 5 contradict movable contact spring 6 so that movable contact 41 contact stationary contact 42 when, buffer stopper 51 is close to movable contact spring 6
End face is abutted with movable contact spring 6, is prevented from causing movable contact 41 to be separated from each other with stationary contact 42 because relay is by external shock, be kept away
It is unstable to exempt from contact contact, it is ensured that the stability of contact contact；Movable contact 41 is consolidated by the fixed plate 7 with toughness simultaneously
Fixed, when movable contact 41 contacts stationary contact 42, elastic deformation can occur for fixed plate 7, there is the work of a buffering to movable contact spring 6
With avoiding contacting firmly between movable contact 41 and stationary contact 42, cause movable contact 41 or stationary contact 42 to damage, so that movable contact 41
It is contacted with stationary contact 42 more stable.
Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can be with other sides
Formula realizes that any obvious replacement is in the protection model of the utility model under the premise of not departing from the technical program design
Within enclosing.
