The purpose of this utility model is to provide a kind of structure more compact, and volume is littler, makes full use of the inner space, improves magnetic efficiency with lifting sensitivity, and makes assembling simple, the sensitive electromagnetic relay of the low clearance of reliable operation.
The utility model is made up of magnetic circuit system, contact system, base and shell, and magnetic circuit system, contact system are arranged in the shell, and magnetic circuit system, contact system are fixed on the base.Magnetic circuit system is provided with armature, coil rack and yoke etc., is provided with push card, quiet spring, moving spring and stage clip etc. by the system of touching.Said magnetic circuit system and contact system are separately fixed in two die cavities up and down of base.A pair of yoke is respectively
Shape and " Contraband " shape structure respectively have an end to insert in the hole of bobbin.
Armature can be movably connected in by stage clip
On one end of shape yoke, the relative working gas gap that forms of an end face of the other end of armature and " Contraband " shape yoke.
Can be provided with through hole on the said stage clip, through hole is installed on the projection of bobbin, and armature is movably connected on the end face of yoke, and the other end of stage clip is connected on the armature.
An end that is connected with push card at armature is bending and is provided with hangnail, and hangnail snaps in the groove of push card.The top of push card and armature active connection place is an arcuate structure.
Be provided with projection on the base side, projection cooperates with the groove of push card, with the scope of activities of restriction armature.Base is provided with the divider wall of dividing plate and separate slot formation.
End at moving spring is established gap slot.
Because magnetic circuit system of the present utility model and contact system are separately fixed in two die cavities up and down of base, the action of armature flexibly connects the switching that realizes electrical contact by the push card that is positioned at the side, base is provided with the divider wall that is formed by dividing plate and separate slot, increased insulation distance, by laterally installing to inserting the contact system that yoke and armature forms, make the relay inner space be fully used, to reduce the relay height dimension, dwindled volume, and can make the magnetic energy of coil excitation more effectively use on the working gas gap, thereby improve pull characteristics, improved action sensitivity.In addition, the magnetic circuit part adopts to clamp with base portion and is connected, and makes assembling simpler, more convenient operation.
