Description

Yoke and iron core integrated electromagnetic relay
The present invention relates to a kind of electromagnetic relay, especially a kind of yoke and the electromagnetic relay that adopts integrated structure design unshakable in one's determination.
Relay extensively applies in various household electrical appliance, the Industry Control electric equipment as a kind of electromechanical compo.In conventional small-sized DC electromagnetic relay, generally comprise coil, coil exit, iron core, yoke, armature, pushing block, movable contact spring, often open static contact spring piece, normally closed static contact spring piece, contact, base, shell.Wherein the magnetic circuit part generally is made up of coil, iron core, yoke, armature, iron core adopts riveting to be connected with yoke, and the pole-face unshakable in one's determination and the armature that pass bobbin form working gas gap, the magnetic circuit part is three, other adds two of part base, the bobbins of support section, number of spare parts is bigger, and cost is higher, causes product can't satisfy low price user's instructions for use.
In the electromagnetic relay of prior art, armature movement direction in the magnetic circuit part is generally along the length direction of iron core, unshakable in one's determination and yoke adopts riveted structure, armature moves on pole-face unshakable in one's determination, armature is in the side plate direction of coil, cause under same power, power consumption situation, the relay construction size is bigger.The CN1255232A patent application discloses a kind of relay with contact spring, and relay has electromagnet system and contact arrangement that has at least one quiet contact spring and at least one moving contact spring of a matrix, belt coil, iron core and an armature.The plate that this contact spring makes the plane respectively with do not have permanent bend to approach at identical plane internal fixation in this matrix.This contact spring is realized the closing of contact by the overlap joint of L shaped end section; In addition, quiet contact spring produces pre-stretching by a corresponding backstop on the matrix.
The object of the present invention is to provide that a kind of magnetic structure is simple, number of spare parts is few, assembling, good manufacturability, can carry out the production of batch flowing water, performance/volume ratio and P/C are than the electromagnetic relay that all is better than existing like product, its input, output reach higher dielectric withstanding voltage, insulation distance can reach VDE0110 fully, part reaches the VDE0700 authentication, can satisfy low price, high performance customer requirements, can be widely used in the white environmental protection household appliances.
For achieving the above object, the invention provides the electromagnetic relay of a kind of low price, simple magnetic line structure, it mainly is made up of contact system, magnetic circuit system, base, contact system comprises often opens static contact spring piece part, normally closed static contact spring piece part, movable contact spring part and pushing block, and inserts in the base by corresponding hole on the base.Magnetic circuit system is made up of coiler part, yoke, armature etc., its base, bobbin integrator, and promptly bobbin side plate has reduced by a base plastic part with the function of base.Yoke and the integrated structure design that adopts unshakable in one's determination, for

The shape structural design makes its cross arm free end and free end unshakable in one's determination form magnetic circuit and is connected, the perpendicular arm of armature and transverse arm formation working gas gap unshakable in one's determination, and especially the yoke position of the integrated iron core of magnetic circuit part also can extend into
Figure C0210269600043
Shape, armature also can extend into Shape is to increase and the corresponding polar area of armature working gas gap.Thereby increased the action suction of relay, the sensitivity that has improved relay.
In addition, because a side plate of bobbin is designed to extend after the broadening structure function with base, design has the narrow groove of the contact system of fixed relay above, contact portion can be installed reliably, therefore reduced by a base part, the part of contact system is fixed on the base by plug-in mounting, easily is automated operation.
