Description
Technical field
The present invention relates to relay technical field, more particularly to a kind of suction is big and the electromagnetism relay of strong shock resistance
Device.
Background technique
Relay is a kind of electronic control device, it have control system (also known as input circuit) and by control system (again
Claim output loop), it is usually applied in automatic control circuit, it is actually to go the one of control larger current with lesser electric current
Kind " automatic switch ".Therefore the effects of playing automatic adjustment, safeguard protection, conversion circuit in circuit.
A kind of electromagnetic relay of the prior art is cooperated in bobbin using U-shaped yoke, and one of U-shaped yoke
Point play the role of iron core, one end of U-shaped yoke cooperates the rotation root of armature as the edge of a knife, U-shaped yoke it is another
End then is used to cooperate the free end of armature, the electromagnetic relay of this structure, since pole-shoe face is limited by yoke as pole-shoe face
The thickness of iron, so that inhaling, boot upper is smaller, and the suction for causing relay is smaller；If necessary to increase pole-shoe face, it is necessary in yoke
Processing increases pole-shoe face on the other end of iron, causes that structure is complicated, and technique is difficult, drawback at high cost.
The electromagnetic relay of the prior art is usually to be mounted in push card between dynamic spring and armature, and push card is actually outstanding
Between armature assembly and movable contact spring, in the case where product (in transport or use process) is impacted or is vibrated, push card
It is easy to be detached from from dynamic spring engaged therewith and armature, relay function is caused to fail.
Summary of the invention
It is an object of the invention to overcome the deficiency of the prior art, provides that a kind of suction is big and the electromagnetism of strong shock resistance
Relay on the one hand can be with by the improvement for the structure that is connected to magnetic circuit part and push card with magnetic circuit part, dynamic spring part
Increase pole-shoe face to increase suction, the impact resistance of product on the other hand can be enhanced.
The technical solution adopted by the present invention to solve the technical problems is: a kind of suction is big and the electromagnetism of strong shock resistance
