Abstract
The relay of the utility model design device against shake, comprise relay base, movable contact spring, static contact, iron core, coil, moving contact, fixed contact, it is characterized in that: fixed touching plate is between upper and lower two static contacts, the back side, top of static contact is above provided with fixed contact, be provided with fixed contact permanent magnet above, the placed on top of static contact is below provided with fixed contact, the back side is provided with fixed contact permanent magnet, the back side on the rear portion of fixed touching plate is provided with former and later two dynamic tactile permanent magnets, iron core is U-shaped iron core, two end points of U-shaped iron core are corresponding with two that the back side on the rear portion of fixed touching plate is arranged dynamic tactile permanent magnets.A stroke backstay relative with movable contact spring is had in the lower rear of movable contact spring.The utility model has the advantages that shake less, efficiency is high, cost is low, volume is little, the life-span is long, low in energy consumption.When overcoming traditional electromagnetic relay contact contact adhesive and release, shake produces electric arc more satisfactoryly, with and make the shortcoming of contact erosion clinkering and then serious curtailment relay life.
Description
Technical field
The utility model relates to a kind of relay of device against shake.
Background technology
Electromagnetic relay is primarily of relay base, iron core, coil, fixed touching plate, the fixed contact be fixed on fixed touching plate, movable contact spring, the moving contact composition be fixed on movable contact spring.Can shake be produced when traditional electromagnetic relay contact contact adhesive and release, the occasion requiring that shake is little can not be used in.Can produce electric arc during contact chatter, electric arc can make contact erosion, clinkering.If do not take certain precautionary measures, shake can have a strong impact on the life-span of relay.Reduce contact chatter, eliminating electric arc is the decisive factor increasing relay life and reliability.At present, the major measure reducing shake during contact adhesive and the release of relay is the method adopting the material changing mechanical parameter and contact spring system, be such as the contact spring system of rigidity for back contact spring, increase contact by pressure, or the front contact spring material that the selection of material density is little, modulus of elasticity large and vibration attenuation coefficient is large, or the length and the raising such as width, the increase thickness freedom from vibration that reduce front contact spring sheet.Although also have some to reduce the design of the electromagnetic relay of shake, the shake of all failing when reducing electromagnetic relay work well.Therefore urgently the jitter problem of existing relay is improved.
Summary of the invention
The purpose of this utility model can produce the problems referred to above existing for shake when being the contact adhesive of electromagnetic relay contact and the release solving prior art repeat circuit, provide a kind of relay of device against shake.The relay of the utility model design device against shake, comprise relay base, movable contact spring, static contact, iron core, coil, moving contact, fixed contact, it is characterized in that: fixed touching plate is between upper and lower two static contacts, the back side, top of static contact is above provided with fixed contact, be provided with fixed contact permanent magnet above, the placed on top of static contact is below provided with fixed contact, the back side is provided with fixed contact permanent magnet, the back side on the rear portion of fixed touching plate is provided with former and later two dynamic tactile permanent magnets, iron core is U-shaped iron core, two end points of U-shaped iron core are corresponding with two that the back side on the rear portion of fixed touching plate is arranged dynamic tactile permanent magnets.A stroke backstay relative with movable contact spring is had in the lower rear of movable contact spring.The utility model has the advantages that shake less, efficiency is high, cost is low, volume is little, the life-span is long, low in energy consumption.When overcoming traditional electromagnetic relay contact contact adhesive and release, shake produces electric arc more satisfactoryly, with and make the shortcoming of contact erosion clinkering and then serious curtailment relay life.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
The relay of device against shake in figure, comprise relay base 1, movable contact spring 2, static contact 3, iron core 4, coil 5, moving contact 6, fixed contact 7, it is characterized in that: fixed touching plate is between upper and lower two static contacts, the back side, top of static contact is above provided with fixed contact, be provided with fixed contact permanent magnet 8 above, the placed on top of static contact is below provided with fixed contact, the back side is provided with fixed contact permanent magnet 8, the back side on the rear portion of fixed touching plate is provided with former and later two dynamic tactile permanent magnets 9, iron core is U-shaped iron core, two end points of U-shaped iron core are corresponding with two that the back side on the rear portion of fixed touching plate is arranged dynamic tactile permanent magnets.A stroke backstay 10 relative with movable contact spring is had in the lower rear of movable contact spring.
The purpose of this utility model is achieved in that the dynamic tactile permanent magnet rigidly connected with movable contact spring at the moving contact back side, iron core is U-shaped iron core, movable contact spring rigid connecting is connected to front permanent magnet and rear permanent magnet, close in opposite directions with two end points of the U-shaped iron core of iron core respectively.The approaching face polarity of dynamic tactile permanent magnet is contrary, dynamic permanent magnet and the surely tactile permanent magnet-be directly in the state of attracting each other of touching, external force can be increased again after contact, contact can keep the suction of sufficient intensity, contact resistance can do very little, very favourable by the ability of big current to relay; The distance that contact separates can be done distant, and the insulating capacity at relay contact two ends is stronger; Contact pressure is independent of each other mutually with contact distance of separation, highly beneficial to the design of relay, relay when adhesive, the damping action that permanent magnet is attracting and make shake obtain larger suppression.Due to the effect that magnet is attracting, distance is nearer, then suction is larger, and distance is far away, then suction is more weak, and therefore, when relay contact once release, then complete whole dispose procedure fast, there will be no contact phenomena, shake when namely exiting also can not produce.
Shake when the utility model overcomes traditional electromagnetic relay contact contact adhesive and release more satisfactoryly and produce electric arc, thus make the shortcoming of contact erosion clinkering and then serious curtailment relay life.After taking above measure, cost is low, volume is little, shake less, efficiency is high, the life-span is long.
Claims (2)
