Abstract
The utility model discloses a flexible ferrite magnetism isolating piece which comprises a square magnetism isolating piece and adhesive plasters covering the two sides of the square magnetism isolating piece. The square magnetism isolating piece is divided into magnetism isolating units which are identical in size. The surface of the each magnetism isolating piece unit is latticed, and the magnetism isolating piece units are fixedly connected through magnetism isolating piece connection portions. The magnetism isolating piece units and the magnetism isolating piece connection portions are integrated. Due to the slender connection of the magnetism isolating piece units through the magnetism isolating piece connection portions, leakage flux can be reduced; due to the slender connection, the magnetism isolating piece units are nearly independent units, so that the overall magnetism isolating piece is high in flexibility; magnetism isolating piece units which are in a regular square shape or other shapes can be formed even if the flexible ferrite magnetism isolating piece is bent and cracked, due to the bonding and fixing effect of the adhesive plasters on the two sides, the electromagnetic performance and the using effect can not be influenced, using is convenient, and cost is relatively lower.
Description
Technical field
The utility model relates to a kind of antifreeze plate, especially a kind of flexible ferrite antifreeze plate.
Background technology
Antifreeze plate is widely used in wireless charging, NFC (close range wireless communication) and RFID (radio-frequency (RF) identification) technical field, can be made into the antifreeze plate in magnetic conduction sheet, NFC and the RFID equipment in wireless charger.Magnetic conduction sheet, in wireless charger, by high magnetic flux, provides loop to the sympathetic magnetic field of charger, raises the efficiency, and by the isolation of electronics eddy current, prevents electronics vortes interference circuit mainboard simultaneously, and charger can normally be worked.Antifreeze plate in NFC and RFID equipment can absorb metal reflection attenuation ripple, can strengthen magnetic field induction distance again, improves communication sensitivity.
Ferrite antifreeze plate in the market exists frangible, and leakage field is large, uses inconvenience, and the defect that cost is high greatly affects antifreeze plate and uses.
Utility model content
Problem to be solved in the utility model is to provide a kind of leakage field that reduces, even and also become regular shape after bending, fracture, do not affect the antifreeze plate of electromagnetic performance and result of use, easy to use, cost is relatively low.
For overcoming the above problems, the utility model by the following technical solutions:
A kind of flexible ferrite antifreeze plate, comprise the adhesive plaster that a square antifreeze plate and square antifreeze plate both sides cover, described square antifreeze plate is divided into the antifreeze plate unit of formed objects, and described antifreeze plate cell surface is latticed, and described antifreeze plate is connected and fixed by antifreeze plate connecting portion between unit.Because the adhesive plaster of square antifreeze plate both sides has viscosity, therefore, antifreeze plate unit can be adhered fixed.
Described antifreeze plate cell surface is latticed, and the size of described antifreeze plate unit is: length 2.5mm, and width 2.5mm, thickness is 0.5mm.
Spacing between antifreeze plate unit is 0.15mm, and the spacing degree of depth is 0.35mm, described antifreeze plate connecting rod width 0.15mm, and thickness is 0.15mm.
Described antifreeze plate unit is identical with antifreeze plate connecting portion material, by the disposable making moulding of mould, is structure as a whole.
The utlity model has following beneficial effect: because pass through this meagre connection of antifreeze plate connecting portion between antifreeze plate unit, can reduce leakage field; Very meagre owing to connecting, antifreeze plate unit is in close proximity to separate unit, and the flexibility of whole like this ferrite antifreeze plate is stronger; Even if described flexible ferrite antifreeze plate yet antifreeze plate unit of square or other shapes of formation rule when bending is ruptured, because the adhesive plaster of both sides is adhered fixed effect, does not affect electromagnetic performance and result of use, easy to use, cost is relatively low.
