Provided is a micro-jitter electromagnetic relay which mainly comprises a static contact whisker spring, a moving contact, a magnetic core, a coil, a moving contact sheet support, a spring, a bracket, a moving contact whisker spring and a static contact. The micro-jitter electromagnetic relay is characterized in that the moving contact is provided with a moving contact point, the static contact is provided with a static contact point, the moving contact point is connected onto the moving contact whisker spring, the static contact point is connected onto the static contact whisker spring, and the contacting part of the moving contact point and the static contact point is an inclined surface. Jitter of the contact points can be effectively reduced when the micro-jitter electromagnetic relay is in use.

Compared with straight surface contact, the micro-jitter electromagnetic relay is large in contact area so that contact resistance is low and passing of relatively high current is facilitated.
Description
Technical field:
The invention belongs to electromechanical engineering technical field, particularly relate to a kind of Design and manufacture of electromagnetic relay of micro-shake.
Background technology:
Electromagnetic relay is the conventional element of electromechanical engineering.Electromagnetic relay mainly by relay base, iron core, coil, yoke, fixed touching plate, spring, be fixed on fixed contact, the movable contact spring on fixed touching plate, the moving contact being fixed on movable contact spring forms.When current electromagnetic relay contact contact adhesive and release, shake can be produced, the occasion that requires shake little can not be used in.During contact chatter, can produce electric arc, 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.Facts have proved, reduce contact chatter, eliminating electric arc is the deciding factor that increases relay life and reliability.At present, when reducing the contact adhesive of relay and discharging, the major measure of shake is the method that adopts the material that changes mechanical parameter and tactile spring system, the tactile spring system that is for example rigidity for back contact spring, increase contact by pressure, or the selection of material density is little, modulus of elasticity large and the large front contact spring material of vibration attenuation coefficient, or length and width, the increase thickness etc. of minimizing movable contact reed improve freedom from vibration.Although the design that also has some to reduce the electromagnetic relay of shake, the shake while all failing to reduce well electromagnetic relay work.
Application number 02141545.5, name is called the innovation and creation of " electromagnetic relay ", has designed a kind of electromagnetic relay of difficult generation runout.This electromagnetic relay comprises: iron core, and plane is roughly J-shaped shape, using an end as supporting receiving portion, using the other end as magnetic pole piece; Movable iron, plane is roughly L font, by being arranged on can supporting by moving contacting plate of bight, and an end to be rotatably supported in the supporting receiving portion of iron core, to make the other end be that adsorption section is relative with the magnetic pole piece of described iron core, and can be adsorbed on this magnetic pole piece.In fact this electromagnetic relay has certain effect on horizontal anti-jitter, but the effect of in the vertical direction anti-jitter not obvious.
Application number 03120338.8, name is called the innovation and creation of " with the electromagnetic relay of the moving spring of flexible bifurcated ", has designed a kind of electromagnetic relay of difficult generation runout.Magnetic circuit part, push card, contact portion and shell, consist of, contact portion is at least provided with normally closed quiet spring part, moving spring part, and contact portion is connected by push card with magnetic circuit part, and moving spring is provided with flexible bifurcated.Owing to establishing flexible bifurcated on moving spring, can be used for reducing the movable stroke of freedom of even eliminating the push card of relay when release condition, therefore improved significantly anti-vibration, the shock resistance of the electromagnetic relay with normally-closed contact.When relay is during in attracting state, push card promotes moving spring towards moving spring direction, can be to be separated from each other between flexible bifurcated and push card, can be to be also in contact with one another, but contact should be significantly less than the pressure of work contact-making surface, less to the performance impacts such as action sensitivity of product.Relay is when attracting state, and it is best mode of the present invention that flexible bifurcated and push card are separated.This electromagnetic relay is complicated structure not only, and the effect of anti-jitter not obvious.
Application number 200710008565.4, name is called the innovation and creation of " electromagnetic relay of resistant to electric repulsive force ", has designed a kind of electromagnetic relay of difficult generation runout.Scheme is when relay contact closure is worked, relay loading, coil adds asserts signal, the second lead-out tablet and movable contact spring current opposite in direction the generation magnetic field that interacts, this magnetic field makes movable contact spring produce electromagnetic force, and the electromagnetic force producing is identical with the motive force direction that push card produces, contact force increases and is enough to the destruction of resistant to electric repulsive force.Designer thinks, its scheme has solved the technical problem of the easy rebound in contact causing because of electrodynamic repulsion force in background technology completely, it also has advantages of as follows: making a concerted effort of electromagnetic force and motive force is large, contact contact is large, contact resistance is little, contact electrically contacts reliably, stablizes, and can resist short circuit current completely, prevents the damage of function relay; Contact change-over power is large, heavy load work for a long time, but switching frequency is unsuitable too fast; Compact conformation, vibration resistance, impact capacity are strong; Carrying load ability is strong, low price, and good manufacturability, can carry out streamline production in enormous quantities.But in fact, can see significantly not only complex structure of this electromagnetic relay, and also unsatisfactory through the effect of experiment anti-jitter.
The jitter phenomenon that the present invention occurs in order to eliminate electromagnetic relay adhesive and to discharge just and the electromagnetic relay Technological improvement plan of making.

Embodiments of the invention are work like this:
(1) adhesive.
At coil 9, be electrified pressure, promote moving contact drive point 8, moving contact 1 is moved to contacting direction with fixed contact 2, while contacting in sound contact, the existence because of moving back contact spring, makes contact chatter obtain great damping.In contact when contact,, to be sound contact cause because of spring noncontact in minimum distance in shake.Because being inclined-plane contact, and sound contact and material all have certain elasticity, allows certain displacement, from whole contact-making surface, some does not contact, and another part contact, and for two ends, sound contact, as long as there is a contact point, whole state is for contact, in on-state.Like this, just effectively reduced shake, each parameter is worked good, and also can reach the effect of non-jitter.
(2) discharge.
In coil 9 power-off, spring 11 promotes moving contact drive points 8, makes moving contact to moving with the fixed contact direction that is separated, because of contact separation speed very fast, once separated, there will be no contact,, when discharging, do not have shake yet and produce.
