Compared with the existing electromagnetic switches, the utility model can save power energy by more than 98% and has the advantages of simple structure, reliable use and no working noise.

Description

The novel moving core of electromagnetic switch

The utility model relates to the novel moving core of a kind of electromagnetic switch, belongs to essential electronic element relay class.

As the electromagnetic switch of electromechanical integrated product, be widely used in the connection of control circuit and disjunction and electromechanical equipment Fraquent start, stop the forward and reverse running with motor.Existing electromagnetic switch, although series, model is various, but its electromagnetic system structure is consistent basically, be that the alternating electromagnetic switch adopts the fabulous selenium steel disc of magnetic property to be overlapped into dynamic and static iron core, the direct solenoid switch is the dynamic and static iron core of moulding cylinder iron, combines formation with coil on placing static iron core.The problem of its existence is:

1, Gong Zuo overall process is all wanted electricity consumption; Especially be in operation, electromagnetic switch has only energising ability maintenance work, and power is big more, and power consumption is many more.

2, the work of alternating electromagnetic switch the time is that the source takes place a noise since the iron core adhesive is tight or since in the electrical network change in voltage can produce various ear-piercing low-frequency noises, serious environment pollution.

3, electromagnetic switch easily caused cause thermal damage because long-play work causes heating.

4, because the line voltage height is unstable, cause its adhesive pressure inequality, frequent electric and magnetic oscillation often makes each position screw loosening, causes the part ablation and causes the motor accident.

The purpose of this utility model is at above-mentioned problems of the prior art, and provides a kind of simple in structure, and it is low to consume electric energy, the novel moving core of the muting electromagnetic switch of operating state.

The technical scheme that realizes above-mentioned purpose is: the novel moving core of a kind of electromagnetic switch, have E type or the U type main body made by the non-magnetic material that cooperate do adhesive with static iron core, its adhesive contact-making surface is provided with square groove, its groove has been embedded in square permanent magnet blocks, is provided with packaging adhesive film on permanent magnet blocks.

The utility model is owing to constitute the moving core of electromagnetic switch with non-magnetic body of material skeleton setting-in permanent magnet blocks, replaces existingly in the superimposed moving iron core that constitutes of selenium steel disc, has following advantage:

1, because just in starting with stop moment and consume small amount of electrical energy, and the coil not electricity consumption fully that is in operation can be saved electricity consumption more than 98%.

2, because there is not the heating burning problems in work coil no current in service.

3, owing to do not keep the adhesive of switch, make the suction-combining force uniform and stable, reduced chance because of pressure inequality, the unstable electric contact scaling loss that causes by the electric power electric energy.

4, because the electromagnetic switch electric and magnetic oscillation that do not exist in service had both been avoided connecting the loosening various switch failures that cause because of vibration causes parts, fundamentally solved noise problem again.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the front view of the moving core of E type agent structure;

Fig. 2 is the profile of Fig. 1;

Fig. 3 is the front view of the moving core of U-shaped agent structure;

Fig. 4 is the profile of Fig. 3.

The utility model is described in further detail below in conjunction with drawings and Examples.

Provide as accompanying drawing, the novel moving core of this electromagnetic switch has according to the static iron core form and definite E type or U type main body 1 can adopt ABS engineering plastics, nylon or other insulating material casting.Each the adhesive contact-making surface that cooperates with static iron core is provided with square groove, groove is embedded in the Nd-Fe-B permanent magnet piece 2 with high magnetic, its permanent magnet blocks is lower than contact end face 1-1.5 millimeter after embedding body recess, use the Instant cement envelope to irritate, end face is polished and forms the packaging adhesive film 3 that places above the permanent magnet blocks.

Claims (1)

1, the novel moving core of a kind of electromagnetic switch, have the E shape or the U-shaped main body (1) that cooperate do adhesive with static iron core, it is characterized in that: the E shape of being made by the non-magnetic material or the adhesive contact-making surface of U-shaped main body (1) are provided with square groove, its groove has been embedded in square permanent magnet blocks (2), is provided with packaging adhesive film (3) on permanent magnet blocks.
