Abstract

The utility model belongs to electric appliance, which takes advantage of a pulse electromagnetic field to realize clutch through mutual action with hard magnetic blocks. The structure of the idle clutch mechanism is composed of a coil former, a coil, a magnet core, hard magnetic blocks and a connect box or rod to form a series of structure. Besides, the idle clutch mechanism is the heart component of a contactor, an intermediate relay, a breaker, a controller, a starter, a relay or an electromagnetic valve. When electromagnets of all above electric appliances are refreshed by idle clutch mechanism, a contactor without watt consumption, a non power consumption intermediate relay, a non power consumption breaker, etc. can be generated. When using, this idle clutch mechanism doesn't need to hold power consumption, and the utility model has advantages of no heating coil, no noise of the alternate current and excellent anti-interference ability.

Description

Idle clutch mechanism

No power consumption clutch is the heart component of contactor, auxiliary relay, circuit breaker, controller, starter, relay, electromagnetically operated valve, belongs to electrical equipment.

Present above-mentioned electrical equipment all uses electromagnet as clutch.Its shortcoming is need keep power consumption, coil heating, adhesive not have AC noise, poor anti jamming capability in real time.

The purpose of this utility model is to design not have the clutch of keeping power consumption, as the clutch part of above-mentioned contactor, relay etc.

The purpose of this utility model is achieved in that in the magnetic pole corresponding position at the two ends unshakable in one's determination of electromagnet installs the Hard Magnetic piece, and the Hard Magnetic piece is fixed on bar or the frame, and then Hard Magnetic piece and bar or frame become one, and as action component, electromagnet is as fixed part.When electromagnet coil is promoted blood circulation towards electric current, electromagnet produces pulsed magnetic field, with homopolar-repulsion, heteropole inhale mutually produce one push away one draw make a concerted effort, when pulse current stops, pulse electromagnetic field also disappears, and the iron core of soft iron was produced different with it polarity and held i.e. locking by the induction of Hard Magnetic piece this moment; And when electromagnet coil leads to the reverse impulse electric current, in like manner produce counteragent and locking, thereby realize clutch.

This parts only need very little startup power consumption, and need not to keep power consumption, so coil does not generate heat, no AC noise, be not subjected to the interference of voltage fluctuation.The electromagnet of above-mentioned contactor, relay etc. upgrades with no power consumption clutch, just becomes Contactor without watt consumption, no power consumption auxiliary relay, no power consumption circuit breaker, no power consumption controller, power consumption starter, no power consumption relay, non-power consumption magnet valve.It is splendid that these electrical equipment need not kept power consumption, no AC noise, antijamming capability.

Be elaborated below in conjunction with accompanying drawing:

Fig. 1 to Figure 11 is the embodiment of no power consumption clutch.Now, be described in detail based on Fig. 1.This no power consumption clutch is by bobbin (1), its outer around coil (2), iron core (3) in the bobbin is formed electromagnet (A), electromagnet can be one and unite use to a plurality of, (3) two ends unshakable in one's determination respectively have one or more the concentrated magnetic pole (4) of magnetic force, its opposite position is equipped with Hard Magnetic piece (5), these Hard Magnetic pieces are installed in frame (6) or press Figure 10, shown in Figure 11 being installed on the bar (7), this frame or bar can pass iron core or in coil periphery, Hard Magnetic piece and frame or bar are formed one and are constituted action component, and electromagnet (A) is for being fixed on for example contactor of other electrical equipment, the fixture of relay matrix or housings or accurate fixture (adding spring or cushion).When electromagnet coil was promoted blood circulation towards electric current, action component and fixture were done relative motion and are leaned on magnetic attracting at one end each other; The logical reverse impulse electric current of coil then is pull-in on the other end.

The shape of unshakable in one's determination (3) is by Figure 1 shows that H shape, Fig. 2 are that 11 shapes, Figure 10 annulated column shape, Figure 11 be U-shaped for in-line, Fig. 8 for the C shape of crouching, Fig. 9 for the king's shape of crouching, Fig. 7 for W shape, Fig. 6 for arrow-shaped, Fig. 5 for cydariform, Fig. 4 for V-arrangement, Fig. 3.Electromagnet (A) can have one also can a plurality ofly to unite (comprising different iron core shapes associatings) to a plurality of associatings thereby whole no power consumption clutch and be applied on the electrical equipment such as above-mentioned contactor, relay.In principle, electromagnet adopts one or two, and iron core shape employing cydariform or H shape are more desirable.

In addition, Hard Magnetic piece (5) is enclosed within the protective cover (8), can improve the mechanical endurance of Hard Magnetic piece like this, and protective cover then is installed on frame (6) or the bar (7).The section of Hard Magnetic piece (5) is that garden, ellipse garden or polygon all can; And its material should use strong permanent magnet material, falls permanent magnetic material as the neodymium iron boron type.

Realize best way of the present utility model:

It is the no power consumption clutch of cydariform that small-sized no power consumption clutch adopts by iron core shown in Figure 3; Medium-sized employing Fig. 1 structure, its iron core are H shape; Large-scale employing Fig. 6 structure, it is unshakable in one's determination to be the king's shape of crouching.

These three kinds no power consumption clutches by bobbin (1), its outer around coil (2), the iron core (3) in the bobbin form electromagnet (A), it is fixture or accurate fixture; Respectively there is 1 to 3 magnetic pole (4) at (3) two ends unshakable in one's determination, in its opposite position frame (6) Hard Magnetic piece (5) are installed, and constitute action component (B).The logical pulse current forward or backwards of coil (B) can produce positive action and sucks or counteragent and sucking at the two ends of (A), thereby realizes clutch, and locking.
