Description

Bifurcation magneto-electric AC relay

Technical field

The utility model relates to a kind of relay, especially relates to a kind of bifurcation magneto-electric AC relay.

Background technology

As everyone knows, the electronic circuit in electrical equipment, instrument, instrument and the control panel can adopt relay to control.Be the power consumption of minimizing complete machine, and keep the stability of required operating state, to control the switching work of electronic circuit exactly, so conventional relay does not all have auto-lock function.And at present openly relay mostly adopt the mechanical type self-locking structure, exist trigger that power consumption is big, defectives such as mechanical wear and poor stability.Comparatively advanced at present for this reason relay is to adopt the action component of magnetic padlock formula electromagnet as relay, solve above-mentioned defective, as CN2669348Y disclosed " bistable state three-phase alternating current relay ", behind coil electricity, the magnet steel assembly is around its rotating shaft rotation, by tilting movement arm catch bar is moved forward and backward, drive the double break crawl contact blade and the fixed contact closed and disconnected that are connected on the catch bar.But its magnetic circuit of the relay of this structure is open magnetic circuit, and magnetic force is little, so it is not high wink to move property.In addition, catch bar is connected with the magnet steel assembly by tilting movement arm, and movement arm and catch bar are certain included angle, therefore also exists the problem of thrust loss, and increases the triggering power consumption of relay.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, can reduce and trigger power consumption, the bifurcation magneto-electric AC relay of self-locking reliable operation.

The utility model is that the technical scheme that achieves the above object is: a kind of bifurcation magneto-electric AC relay, comprise housing, coil, yoke, armature, magnet steel and be arranged on fixed contact in the housing, insulation push rod and double break point movable contact spring, it is characterized in that: described yoke is closed, and yoke is provided with the magnet steel of symmetry, armature places between coil and two magnet steel, armature shaft is to extending coil and yoke and axially being connected with an end of insulation push rod, double break point movable contact spring is horizontal on the insulation push rod, and the back of double break point movable contact spring joins with the spring that is arranged on the insulation push rod.

The utility model adopts the advantage of technique scheme to be: 1, yoke of the present utility model is a closed, therefore can form enclosed magnetic loop, and under the prerequisite of identical number of turn coil, magnetic force is bigger.After pulse electrical signal is given coil, armature axial displacement rapidly, and behind the coil blackout, under the effect of magnetic confining field, make the invariant position after armature remains on the energising displacement, and no longer need pulse electrical signal just can keep, very power saving.The utility model can make armature do axial motion behind coil electricity, and can remain on two different positions, and export identical moment and make the insulation push rod drive double break point movable contact spring to move, make double-contact movable contact spring and the fixed contact rapid closing and the disconnection of relay, reach the current circuit of main control system load or the on-off action of signal circuit.2, insulation push rod of the present utility model directly with armature shaft to being connected, simple in structure, owing to there is not the loss of thrust, it is little therefore to trigger power consumption, double-contact movable contact spring and fixed contact closed and disconnected be swift in motion, light, it is good that wink is moved property.3, the utility model adopts magnetic confining field that armature is carried out self-locking, and self-lock force is big, and locking is reliable, not only is suitable for the break-make of control single phase poaer supply, but also can be used for three-phase alternating current.4, the utility model is provided with pressing plate between double-contact movable contact spring and spring, therefore when the insulation push rod moves and drives the action of double-contact movable contact spring, the double-contact movable contact spring is then under pressing plate function, keep synchronously when making two moving contacts and fixed contact closed, it is constant that the pressure when making each phase closing of contact keeps.
