Summary of the invention
The polarized relay that the purpose of this invention is to provide a kind of double-acting air gap of armature-setting reliable and replacement convenient.
Electromagnetic relay of the present invention is made up of base portion, magnetic circuit part, shell at least, and base portion comprises base, moving spring part, quiet spring part at least.The magnetic circuit part comprises armature part, coiler part at least.Coiler part comprises iron core, coil, antifreeze plate.Armature partly comprises magnet steel, two armature, promotes part, and magnet steel is between two armature.Armature, magnet steel, formation bridge-type magnetic circuit unshakable in one's determination.Two non-working-gaps of bridge-type magnetic circuit are equipped with antifreeze plate, form the double-acting air gap magnetic circuit, and armature partly is the action component of magnetic circuit, and the rotating shaft of armature part is in the non-working-gap side.All there is bending the both sides that reach up and down of antifreeze plate, guarantee the reliable location of armature part, can utilize the one or both sides antifreeze plate to position.The promotion of armature part cooperates the location up and down of the front portion that guarantees the armature part partly with positioning boss with moving spring.
The area of the crushed element of the antifreeze plate of electromagnetic relay of the present invention reduces, and can increase its flexibility, when guaranteeing that armature is partly packed into, antifreeze plate is in regime of elastic deformation, armature partly pack into put in place after, the top bending of antifreeze plate can recover the position, guarantees that armature partly locatees.After armature was repeatedly got dress, antifreeze plate can keep original shape substantially, made things convenient for armature to change.
Dogleg section has chamfering on the antifreeze plate, makes things convenient for armature partly to pack into.
The last dogleg section of the antifreeze plate of electromagnetic relay of the present invention has chamfering, makes things convenient for armature partly to pack into.
