The purpose of this utility model 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 utility model 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 are shape structure, and transverse arm unshakable in one's determination has the effect of yoke.Armature also is shape structural design, and its cross arm free end forms magnetic circuit with free end unshakable in one's determination and is connected, the perpendicular arm of armature and transverse arm formation working gas gap unshakable in one's determination.Base is provided with and is used for fixing movable contact spring, often opens the narrow groove of static contact spring piece, normally closed static contact spring piece, and also design has a plurality of ditches, groove simultaneously, is used for the wall thickness of even base each several part, improves base high temperature deformation resistance ability.When design, take into full account the insulation distance of contact portion and magnetic circuit part, increase electrical distance, creepage distance as far as possible, penetrate insulation distance, improve the isolation of input, output, thereby reach the purpose that improves dielectric withstanding voltage.
Because yoke and the integrated shape structural design of employing unshakable in one's determination, its transverse arm has the effect of yoke, makes the magnetic structure of electromagnetic relay simple, and number of spare parts is few, and assembling is good, has improved performance/volume ratio and P/C ratio.Because armature also adopts shape structural design, make its cross arm free end and free end unshakable in one's determination form magnetic circuit and be connected, the perpendicular arm of armature and transverse arm formation working gas gap unshakable in one's determination, especially the yoke position of the integrated iron core of magnetic circuit part also can extend into
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.
