1. Open the mobile phone jacket, plug the receiving module into the charging port, connect the patch to the charging port of the mobile phone, and then put it on, remember to face up. Due to chargerThe magnetic field transmits energy between the electric device and the electric device, and there is no wire connection between the two, so the charger and the electric device can be non-conductive contact exposed. It is important to note that whether it is a mobile phone or a charging bank, it has a wireless function, that is, a wireless coil.
2, the principle of wireless charging treasure is to use wireless electromagnetic energy transmission technology to charge mobile devices. This technology enables the mobile device to be charged by establishing a radio magnetic field between the wireless charger and the mobile device, which transmits electrical energy from the wireless charger to the mobile device. Wireless power banks usually consist of two parts: wirelessMaster of the press, ferrite, iron powder core, nickel zinc, manganese zinc, yellow...
Ferrite includes two kinds of manganese zinc and nickel zinc, manganese zinc material common shape of the core E type, T (ring) and so on. Has a high saturated magnetic flux density, has a good low loss/frequency relationship and low loss/temperature relationship, and low resistivity (equivalent to conductors).
Iron powder core Iron powder core is a popular term for magnetic core material ferric oxide, the main component is iron oxide, the price is relatively low, the saturation magnetic induction intensity is about 4T: the permeability ranges from 22 to 100, the initial permeability ui value is stable with the change of frequencyGood performance, DC current superposition performance is good, but high consumption at high frequency.
Magnetic powder core, ferrosilicon aluminum core, ferrite core, manganous-zinc ferrite core, nickel-zinc ferrite core. Manganese - zinc ferrite and nickel - zinc ferrite are typical magnetic core materials. Manganese zinc ferrite has the characteristics of high permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has very high impedance and low permeability of less than a few hundred.
The most common materials of magnetic core are ferrite, iron based nanocrystals (good performance, expensive), silicon steel. The core is all magnetic, but it's losing powerThe specific remanence size is determined by the coercivity and softness of the iron core.
Iron core: Iron core is the most commonly used soft magnet core in the I-inductance magnetic core, this magnetic core is generally formed by using pure iron powder, adding insulating agent, binder and then extruded. (2) nickel-zinc magnetic core: The nickel-zinc magnetic core applied in the H-inductance magnetic core belongs to a soft magnetic ferrite core, which has high resistance, low permeability, and the initial permeability range of 5~1500 characteristics.
is mainly to replace the iron powder core, the loss is 80% lower than the iron powder core, can be used at a frequency of more than 8kHz; Saturation magnetic sensing at 0About 5T; The permeability ranges from 26 to 125; The magnetostriction coefficient is close to 0, and there is no noise when working at different frequencies. Higher DC bias capability than MPP; It has the best performance-price ratio. It is mainly used in AC inductors, output inductors, line filters, power factor correction circuits, etc.
Wireless strip principle: The wireless socket uses infrared sensing technology to remotely turn on power through infrared reception. The wireless smart socket integrates one programmable (PLC) automatic control insideThe safety and energy saving converter and electrical intelligent standby power saving socket are integrated, which can automatically detect current changes through intelligent IC chips, so as to realize automatic standby and shutdown operations of electrical appliances.
The main function of the wireless wifi socket is manual switching, receiving the indoor remote control instructions to achieve the remote control switch, timing switch, full on and full off, delay off and other functions, and accepting the remote controller instructions to achieve remote control. The installation and wiring of the smart socket is exactly the same as that of the traditional socket. The wireless socket uses infrared sensing technology to remotely turn on power through infrared reception.
The principle of the wireless socket is actually to change the idea of the conventional transformer, the transformer's power supply coil is really connected to the conventional power supply circuit by the wire, and the transformer's iron core part is also at this end. The output coil of the transformer is done at one end of the electrical appliance, so that, taking the razor as an example, there is no wire connection charging jack, and the electric coil can be completely sealed inside the razor to achieve the purpose of complete waterproof.
Wireless smart socket is a new type of safety socket that integrates a programmable PLC automatic control safety and energy saving converter and an intelligent standby power saving socket for electrical appliances. Its workThe principle is: the use of infrared induction to turn on the power supply, electrical appliances begin to use normally. By embedding the smart IC chip in the socket to automatically detect current changes online to achieve a period of time (30s, 5 minutes, 30 minutes, etc.) after the electrical standby and automatic power off, completely eliminate the problem of standby energy consumption.
What is the principle of the wireless socket The principle of the wireless socket is to use infrared induction technology to remotely open the power supply by infrared reception. The interior of the wireless socket is integrated with the intelligent standby power saving socket and a programmable logic (PLC) automatic control safety and energy saving converter, so thatThrough the intelligent IC chip to automatically detect current changes, so that household appliances can automatically standby and shutdown operations.
Principle Different Wireless socket is made of electromagnetic induction principle, must have a transmission and reception composition. That is, the main device into which the wireless socket is inserted must have a transmission received by the socket itself. A cable outlet is not. Efficiency The conversion efficiency of different cable sockets is strong, and the conversion efficiency of wireless sockets is very general. A socket with a different appearance and no cable, we call it a wireless socket. It's a separate outlet, no power cord attached.
1, soft magnetic ferrite is a ferromagnetic oxide with Fe2O3 as the main component, produced by powder metallurgy. There are Mn-Zn, Cu-Zn, Ni-Zn and other classes, of which Mn-Zn ferrite production and dosage is the largest, Mn-Zn ferrite resistivity is low, 1 ~ 10 ohms/meter, generally in the frequency of 100kHZ below the use.
2, widely used in high Q filter, tuned filter, load coil, resistanceAnti-matching transformer, proximity sensor. Broadband ferrite is often said to be a high permeability ferrite, the permeability of 5000, 10000, 15000. It is characterized by low loss factor, high permeability, and high impedance/frequency characteristics.
3, permanent magnet ferrite: After magnetization, the strength of the residual magnetic field is very high, and the residual magnetic field can be maintained for a long time. Usually used as a permanent magnet material. For example: speaker magnet. Soft magnetic ferrite: When the magnetizing magnetic field disappears, the residual magnetic field is small or almost no. It is usually used as a choke, or the magnetic core of an intermediate frequency transformer.
4. SpinelSoft magnetic ferrite main types of manganese zinc ferrite, nickel zinc ferrite, used in transformers, bound magnetic field to reduce magnetic loss magnetic lead-stone permanent magnet ferrite - strontium ferrite used as a magnet for telecommunications devices such as voice recorders, telephones and various instruments, has now been used in medical, biological and printed displays and other aspects have also been applied.
5, and the moment magnetic material is unique: /Br and BS are equal, coercivity Hc is not large, the hysteresis loop is rectangular, such as manganese magnesium ferrite and lithium manganese ferrite. This property makes them useful in computer binary systems, especially as "memory" components,Store and represent "0" and "1".
6, soft magnetic ferrite core is widely used in all kinds of energy-saving lamps, electronic ballasts, power transformers, power filters and so on. Nowadays, soft magnetic ferrite materials have become a kind of functional materials with wide application and variety. The development of soft magnetic ferrite core is mainly manifested in three aspects: (1) to high frequency development: with the requirements of the development of information technology and new green lighting in recent years, the material has further developed to high frequency, high permeability and low loss.
