Description
Technical field
The utility model relates to the technical fields of magnetic core, more specifically, it relates to a kind of ferrite antifreeze plate.
Background technique
Antifreeze plate is widely used in wireless charging, NFC (close range wireless communication) and RFID (radio frequency identification) skill
Art field can be made into the magnetic conduction sheet in wireless charger, the antifreeze plate in NFC and RFID equipment.Magnetic conduction sheet is in wireless charging
In device, by high magnetic flux, circuit is provided to the sympathetic magnetic field of charger, improves efficiency, while electronics being vortexed and is isolated, prevents electricity
Sub- vortes interference route mainboard, enables charger to work normally.Antifreeze plate in NFC and RFID equipment can absorb metal
Reflection attenuation wave, and magnetic field induction distance can be enhanced, improve communication sensitivity.
Ferrite antifreeze plate used at present is all to have the thin magnetic conductance of thickness by magnetic flakes made of high temperature sintering
The features such as rate is high.But since the technology of existing wireless telecommunications is more mature, realize that remote wireless charging has changed into
May, but existing ferrite antifreeze plate can no longer meet requirement.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of structurally reasonable simple, it is practical
Strong, the strong antijamming capability of property, is remarkably improved the ferrite antifreeze plate of magnetic field strength.
To achieve the above object, the utility model provides following technical solution:
A kind of ferrite antifreeze plate, including magnetic sheet its ontology, ontology is rounded, ontology include upper magnetosphere, middle magnetosphere and under
Magnetosphere is equipped with several grooves on the upper and lower end face of middle magnetosphere, and the groove of upper and lower end face is in dislocation arrangement, upper magnetosphere, lower magnetic
Several double wedges being adapted to groove, structure between the outer wall of double wedge and the cell wall of groove are constituted on the fitting end face of layer and middle magnetosphere
At there is receiving channel, receiving channel is provided with magnetic pole, chamber interconnected there are three tools in the magnetic pole, fills out in three chambers
Filled with nano-magnetic powder.
By using above-mentioned technical proposal, the magnetic that reburns after being combined using three magnetic sheets constitutes single magnetic sheet ontology.Due in
The groove of two end faces is dislocation arrangement above and below magnetosphere, so the double wedge that upper magnetosphere and lower magnetosphere are adapted to groove is also in that dislocation is set
It sets, and then substantially increases the bonding strength and connective stability between magnetosphere, middle magnetosphere and lower magnetosphere.The placement of magnetic pole rises
To enhancing high magnetic flux, and the size by filling nano-magnetic powder amount in magnetic pole realizes the nearly remote control to wireless charging
System.The nano-magnetic powder be ferroferric oxide magnetic powder, under external magnetic field can displacement, and outside plus alternating electromagnetic field effect
Under can generate heat.
The utility model is further arranged to: three chambers of the magnetic pole are respectively first chamber, second chamber and
Three chambers, the diameter of second chamber are less than the diameter of first chamber and third chamber.
It can be oriented under external magnetic field by using above-mentioned technical proposal since nano-magnetic powder is ferroferric oxide magnetic powder
It is mobile, so three chambers are set by magnetic pole, and the diameter of intermediate second chamber will be arranged less than other two chambers,
It ensure that the stability of nano-magnetic powder movement and the structural stability of magnetic pole.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model magnetic pole.
Specific embodiment
The embodiments of the present invention are described further referring to figs. 1 to Fig. 2.
The present embodiment specific structure: including its ontology of magnetic sheet, ontology is rounded, ontology include upper magnetosphere 1, middle magnetosphere 2 and
Lower magnetosphere 3, is equipped with several grooves on the upper and lower end face of middle magnetosphere 2, the groove of upper and lower end face in dislocation arrangement, upper magnetosphere 1,
Several double wedges 4 being adapted to groove, the outer wall of double wedge 4 and the slot of groove are constituted on the fitting end face of lower magnetosphere 3 and middle magnetosphere 2
Constituting between wall has receiving channel, and receiving channel is provided with magnetic pole 5, chamber interconnected there are three tools in the magnetic pole 5, and three
Nano-magnetic powder is filled in chamber.
The magnetic that reburns after being combined using three magnetic sheets constitutes single magnetic sheet ontology.It is recessed due to about 2 two end faces of middle magnetosphere
Slot is dislocation arrangement, so the double wedge 4 that upper magnetosphere 1 and lower magnetosphere 3 are adapted to groove is also in shift to install, and then substantially increase
Bonding strength and connective stability between upper magnetosphere 1, middle magnetosphere 2 and lower magnetosphere 3.The high magnetic flux of enhancing is played in the placement of magnetic pole 5
Amount, and the size by filling nano-magnetic powder amount in magnetic pole 5 realizes the nearly far distance control to wireless charging.The nano magnetic
Powder is ferroferric oxide magnetic powder, under external magnetic field can displacement, and outside plus alternating electromagnetic field effect under can generate heat
Amount.
Three chambers of magnetic pole 5 are respectively first chamber 51, second chamber 52 and third chamber 53, second chamber 52 it is straight
Diameter is less than the diameter of first chamber 51 and third chamber 53.
Since nano-magnetic powder is ferroferric oxide magnetic powder, under external magnetic field can displacement, so set magnetic pole 5 to
Three chambers, and the diameter of intermediate second chamber will be arranged less than other two chambers, ensure that nano-magnetic powder movement
The structural stability of stability and magnetic pole 5.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
