Problems solved by technology

At present, in the flat cable industry, an aluminum foil layer or a copper foil layer is usually used to achieve the EMI effect (anti-electromagnetic interference effect). However, when there is DC or low-frequency magnetic field interference in the system, the EMI effect is not obvious, which affects the flat cable. High frequency performance of the cable

Embodiment Construction

[0011] see figure 1 As shown, the flat cable 10 according to the first embodiment of the present invention includes a pair of insulating films 11, a plurality of flat conductors 12 sandwiched between the pair of insulating films 11 and arranged at intervals from left to right, and sequentially covered on the outside of one of the insulating films 11. An adhesive layer 13 , a dielectric layer 14 , two bonding layers 15 , and an outer coating layer 16 .

[0012] Adhesive layer 13 and bonding layer 15 are double-sided adhesive or hot-melt adhesive, dielectric layer 13 is made of PET, PE, PP or CPP material, in order to adjust the dielectric coefficient of flat cable 10, the higher the dielectric coefficient The smaller the value, the faster the signal transmission rate.

[0013] The surfaces of the two adhesive layers 15 are bonded with magnetically permeable materials, such as ferrite or rare earth permanent magnet powder, so that the adhesive layer 15 has low reluctance, and a...

Abstract

The invention relates to a flat cable which comprises a pair of insulating films, a plurality of conductors, a dielectric layer, at least one bonding layer and a coating layer, wherein the conductors are clamped between the insulating films and arranged left and right at intervals, and the dielectric layer, the bonding layer and the coating layer sequentially cover the outer side of one insulating film; the dielectric layer is made of PET, PE, PP or CPP; the surface of the bonding layer is bonded with a permeability magnetic material, and the bonding layer can provide a good EMI effect. The high-frequency performance of the flat cable is improved.

Description

technical field [0001] The invention relates to a flat cable, in particular to a flat cable with high frequency performance. Background technique [0002] Flexible Flat Cable (FFC for short) is a new type of data cable made of PET insulating material and extremely thin flat copper wire through the production line of high-tech automatic equipment. , small size, simple connection, easy disassembly, easy to solve electromagnetic shielding (EMI) and other advantages. At present, in the flat cable industry, an aluminum foil layer or a copper foil layer is usually used to achieve the EMI effect (anti-electromagnetic interference effect). However, when there is DC or low-frequency magnetic field interference in the system, the EMI effect is not obvious, which affects the flat cable. high-frequency performance of the cable. [0003] Therefore, it is necessary to design a new flat cable to solve the above technical problems. Contents of the invention [0004] The object of the p...
