Abstract

The utility model discloses a high-efficient energy-saving controller. The energy-saving controller is formed by means that an iron core (4) and a coil bobbin (3) wound with coils (2) is fixed on an outer casing (1), and then a permanent magnet (7) is fixed on an insulating frame (6) supported by a spring. The utility model has the advantages of simple structure, raw materials saving, no noise in running, small energy consumption and reliable use. The utility model can be used in controller industry.

Description

High-efficient energy-saving controller

The utility model provides a kind of energy-saving controller, belongs to the electrical apparatus industry technical field, especially suitable the manufacturing 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, be built-in with coil (line bag) at housing, cored in the skeleton of coil, an 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 with the pulling of the iron core in the coil rack, thus the feasible insulating frame displacement together that is fixed with sheet metal, the conductor that sheet metal is mated use contacts, and connects the circuit of control; If want open circuit, cut off the power supply of coil, coil loses 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 utility model is the above-mentioned defective that exists at existing controller and a kind of novel energy-conserving controller that provides, noiselessness, energy savings and save material when producing during the sort controller operation.

Taked following technical scheme in order to realize the purpose of this utility model:

The coil rack and the iron core in the coil rack that controller are contained coil are fixed in the shell body; And will be fixed with the fixing permanent magnet of going up of another side of the insulating frame of sheet metal, and support by spring between insulating frame and shell, make energy-saving controller.

Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:

Fig. 1, the utility model are preferentially selected the broken section structural representation of an embodiment for use.

Fig. 2, spring place the structural representation between coil rack and the insulating frame.

The schematic diagram of Fig. 3, twin coil, dual permanent-magnet structure controller.

Fig. 4, iron core bottom are equipped with the structural representation of permanent magnet.

In the structural representation of Fig. 1, Fig. 2, Fig. 3, Fig. 4,1 among the figure is the shell of controller, and shell 1 internal fixation has the coil rack 3 that contains coil 2, and coil 2 is on coil rack 3; In coil rack 3, be equipped with iron core 4.Iron core 4 and contain the coil rack 3 of coil 2 all is fixed in the controller housing 1.In shell 1, also put spring 5.Spring 5 is two springs, places the both sides of shell 1 interior loop 2 symmetrically.The other end of spring 5 props up insulating frame 6.In the one side of insulating frame 6 towards coil 5, be fixed with permanent magnet 7, the position of permanent magnet 7 is corresponding with iron core 4.The other one side of insulating frame 6 is connected with sheet metal (not drawing), is used to connect the Be Controlled circuit.

Operation principle of the present utility model is, the working power of closing coil 2, make in the coil 2 electric current is arranged, in iron core 4, produce an electromagnetic field this moment, the polarity of this electromagnetic field and permanent magnet 7 is different, therefore produces suction, makes permanent magnet 7 and iron core 4 inhale together, the sheet metal that is fixed in insulating frame 6 another sides is connected the Be Controlled circuit, the beginning normal power supply; Disconnect the working power of coil 2 this moment, do not have the electric current mistake in the coil 2, and iron core 4 does not have electromagnetic field yet, but because of the effect of permanent magnet 7 is arranged, permanent magnet 7 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 signals of telecommunication of coil, this reverse impulse to make iron core 4 produce an electromagnetic field with permanent magnet 7 same polarities, thereby make electromagnetic field and permanent magnet 7 generation repulsion, this repulsion is pushed permanent magnet 7 open, disconnects controlled circuit.If need connect the Be Controlled circuit again, repeat the aforesaid operations process and get final product.

The utility model is to be fixed in that the reciprocating iron cores 4 of insulating frame 6 disconnect with insulating frame 6 and with iron core 4 be placed in iron core 4 outer coil racks 3 and be fixed in the shell 1 with former, only on insulating frame 6, fix a permanent magnet 7 again, therefore make the utility model energy-saving controller and be very easy to realize.

Because iron core 4 is fixed in the shell 1, permanent magnet 7 weight fixing on the insulating frame 6 are lighter, therefore the elastic force of spring 5 that is used for supports insulative frame 6 is also less, add that coil 2 energising moment iron cores 4 produce the graviational interaction of the magnetic pole generation opposite with permanent magnet 7, do not need very big electromagnetic force to hold permanent magnet 7, can save material when therefore producing iron core 4 and coil 2; The utility model is in operation and keeps operating state by permanent magnet, both energy savings, and noiselessness, thus and do not give birth to fluctuation and cause misoperation to realize the purpose of this utility model because of the electricity of electrical network.

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

1, simple in structure, easy to manufacture, save material, cost is low.

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

The spring 5 that the utility model is used also can place between as shown in Figure 2 the coil rack 3 and insulating frame 6; The utility model can also be made the controller of twin coil dual permanent-magnet as shown in Figure 3, its structure is as the controller of two unicoil list magnet structures and be fitted together, the utility model can be at iron core 4 bottom fixing permanent magnets 8, to improve rate of release.
