Description

The permanent magnetism controller

The utility model relates to a kind of efficient permanent magnet controller, is applicable to make as electric equipment products such as A.C. contactor, relays.

Controller is indispensable electric equipment products in the industrial production, is mainly used in the break-make of control circuit.Conventional controller has a housing, solenoid (line bag) is installed in housing, cored in the skeleton of coil, one end of iron core is connected with insulating frame, is fixed with sheet metal on insulating frame, behind coil electricity, generate an electromagnetic field in coil, this electromagnetic field is to be fixed with the insulating frame displacement together that metal belongs to sheet with the pulling of the iron core in the coil rack thereby make, and sheet metal is mated the conductor contact of use and connects the circuit of control; If will disconnect controlled circuit, need to cut off the power supply of coil, make coil lose electric current, magnetic field diminishes, the iron core that is connected with insulator loses magnetic attraction, sets back under the effect of spring, disconnects the circuit of control.There is following defective in this existing controller:

One, waste raw material: because coil and iron core all are mobilizable, just must leave activity space, just needing that iron core is done like this is big, add movable core certain weight is arranged, the strength that coil is produced overcomes the weight of iron core and the strength of spring moves iron core, coil is increased, and the also corresponding increase of shell causes the waste of raw materials of iron core and coil and shell like this.

Two, waste energy; Keep Be Controlled circuit normal power-up, just must make coil that operating current is arranged always, cause energy waste like this.

Three, noise is big: controller produces when operation and exchanges noise, contaminated environment.

The purpose of this utility model provides a kind of novel permanent magnetism controller, and it is big to solve the operating noise of controller effectively, wastes energy and the waste problem of raw material

The purpose of this utility model is achieved like this, the skeleton and the intraskeletal iron core that are wound with coil is fixing in the enclosure, and the insulating frame that will be fixed with sheet metal is connected guide rod one end, the guide rod other end is fixed with permanent magnet, permanent magnet is packed between two iron cores, and sliding guide is packed in the core center hole.

The utility model is simple in structure, easily produces, and noiselessness, energy savings and raw material are easily applied, and good economic and social benefit is arranged.

Below in conjunction with accompanying drawing the utility model structure and working condition are elaborated.

Fig. 1 is the utility model structural front view (partly cut-away).

Fig. 2 is a two coil configuration controller front view (partly cut-away).

Provide by Fig. 1, the utility model is by shell, coil and skeleton constitute, be wound with coil 2 on the skeleton 3 in the shell 1, iron core 4 and iron core 5 are housed in the skeleton 3 that is wound with coil 2, gapped between iron core 4 and the iron core 5, there is a clear opening at the center of iron core 5, sliding guide 7 is housed in clear opening, sliding guide 7 one ends are fixed with permanent magnet 6, permanent magnet 6 places in the gap between iron core 4 and the iron core 5 (movable), the magnetic pole strength of permanent magnet 6 is corresponding with iron core, and the other end of sliding guide 7 is connected with insulating frame 8, sheet metal (not drawing) is housed above the insulating frame 8 is used to connect controlled circuit.Coil 2 is divided into two groups of line bags in a skeleton 3, it is different and more or less that every group of number of turns looked the big ting model of controller specification, and it is identical that two groups of lines hold the line direction.The utility model can be by forming more than two, and what Fig. 2 provided is exactly by two examples that constitute.

Working condition of the present utility model is, the working power of closing coil 2, make in the coil 2 electric current is arranged, produce an electromagnetic field this moment in iron core 4 and iron core 5 gaps, this electromagnetic field acts on mutually with the polarity of permanent magnet 6, therefore produces repulsion and suction, make permanent magnet 6 and iron core 4 inhale together, and making sliding guide 7 drive insulating frame 8 displacements, the sheet metal that is fixed in above the insulating frame 8 is connected the Be Controlled circuit, the beginning normal power supply; Disconnect the working power of coil 2 this moment, do not have electric current to flow through in the coil 2, and iron core 4 does not have electromagnetic field yet, but because of the effect of permanent magnet 6 is arranged, permanent magnet 6 and iron core 4 are still tightly inhaled together, and the utility model is in little energy consumption operating state; If will disconnect the power supply of Be Controlled circuit, only need to give 2 one reverse impulse electric currents of coil, this reverse current makes iron core 4 produce an electromagnetic field with permanent magnet 6 same polarities, thereby make electromagnetic field and permanent magnet 6 produce repulsion, this repulsion is pushed permanent magnet 6 open, it is adsorbed on the iron core 5, and sheet metal disconnects controlled circuit on sliding guide 7 interlock insulating frames 8.If need connect the Be Controlled circuit again, repeat the aforesaid operations process and get final product.

Because iron core 4 is fixed in the shell 1, permanent magnet 6 weight fixing on the moving guide rod of the bone that insulating frame 8 connects are lighter, coil 2 energising moment iron cores 5 produce the repulsion of the magnetic field generation identical with permanent magnet 5, iron core 4 produces the graviational interaction of the magnetic pole generation opposite with permanent magnet 6, does not need very big electromagnetic force that permanent magnet 6 is adsorbed on the iron core 4.Can save material when therefore producing iron core and coil 2; The utility model is in operation and keeps operating state by permanent magnet, both energy savings, and noiselessness, and do not cause misoperation because of the voltage fluctuation of electrical network, thus realized the purpose of this utility model.

The utility model is compared with existing procucts and is had the following advantages:

1, simple in structure, easy to manufacture, save material.

2, operation noiselessness, free from environmental pollution, micro energy consumption.

3, connection and disjunction circuit speed are fast, reliable operation.
