Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in figure 13, the embodiment of the present invention one comprises copper conductor 51, as the electromagnetic shielding film 52 of screen, and electromagnetic shielding film 52 is coated on outside copper conductor 51, so that the use of electromagnetic shielding to be provided.This embodiment mono-does not have outer by structure, should be as the built-in wire rod of electronic equipment, independent utility.
Shown in Figure 14, the embodiment of the present invention two comprises many copper conductors 51, electromagnetic shielding film 521, electromagnetic shielding film 522, parallel between many copper conductors 51, interval arranges, electromagnetic shielding film 521 is coated on many copper conductors 51 1 sides, electromagnetic shielding film 522 is coated on many copper conductors 51 opposite sides, 510 places, space between two adjacent copper conductors 51, electromagnetic shielding film 521, electromagnetic shielding film 522 connect as one, with two copper conductors 51 of space between adjacent.This embodiment bis-can be used as the use of the winding displacement of electronic equipment.
As shown in Figure 15-Figure 17, the embodiment of the present invention three is RG series wire rod, and its production process comprises substantially: the operation one shown in Figure 15 covers PE material layer 32, to guarantee copper conductor 31 insulation on the copper conductor 31 for signal transmission.Operation two shown in Figure 16, the coated electromagnetic shielding film 33 in PE material layer 32 outsides.Operation three shown in Figure 17, outside electromagnetic shielding film 33 outsides are coated, by 34, so far, RG wire product completes.Visible, compared with prior art, its production process, material all have obvious minimizing.
As shown in Figure 18-Figure 22, the embodiment of the present invention four is Lan cable series wire rod, and its production process comprises substantially: the operation one shown in Figure 18 covers PE material layer 42, to guarantee copper conductor 41 insulation on the copper conductor 41 for signal transmission.Two, two strands of heart yearn pair twists of operation shown in Figure 19, to guarantee electrical characteristic.Operation three shown in Figure 20, the heart yearn after multiply pair twist always twists.Operation four shown in Figure 21, at multiply heart yearn, ground wire and crossing skeleton line outer cladding electromagnetic shielding film 43.Operation five shown in Figure 22, outside electromagnetic shielding film 43 outsides are coated, by 44, so far, Lan cable wire product completes.Visible, compared with prior art, its production process, material also all have obvious minimizing.
As shown in figure 23, the first electromagnetic shielding film provided by the invention comprises insulating barrier 62, conductive layer 63.Before being coated on wire rod, two outer surfaces of insulating barrier 62, conductive layer 63 are also coated with protective film 61, protective film 62.
As shown in figure 24, the second electromagnetic shielding film provided by the invention comprises insulating barrier 72, metal level 73, conductive layer 74.Before being coated on wire rod, two outer surfaces of insulating barrier 72, conductive layer 74 are also coated with protective film 71, protective film 75.
In above-mentioned two kinds of electromagnetic shielding films, protective film 61, protective film 62, protective film 71, protective film 75 can, for PET, wheat are drawn, paper-like materials, as the use of protecting before using electromagnetic shielding film, be abandoned in manufacturing process.Insulating barrier 62, insulating barrier 72 can be resinae, silicone class mixture, produce insulation function.Insulating barrier 62, insulating barrier 72 also can adopt double-decker, are divided into layer insulating and lower layer insulating, to produce better insulation effect.Metal level 73 can be used the metals such as copper, silver, as conducting, uses.Conductive layer 63, conductive layer 74 can be used copper, silver-colored class etc. side's property or anisotropic conductive, major function is conducting effect.
As from the foregoing, the present invention can use for RF, RG, FFC series wire rod or communication coaxial cord, cable.When utilizing the present invention to manufacture all kinds of wire rods, cable, " holding wire insulation " carried out according to current electric wire production standard technique with " braiding winding working procedure " step.As the electromagnetic shielding film of " single shielding material ", through after coated, hot extrusion, can complete coated operation, simple.Outermost " outward by " operation is carried out according to electric wire production standard technique at present." outward by " operation for not needing to carry out does not have the built-in line of appearance requirement simultaneously, and the electromagnetic shielding film of can directly usining is used as " outward by ", saves outer by operation and cost.
To sum up, the present invention can obtain following beneficial effect:
A large amount of uses of saving material, for environmental protection is made one's effort.
A large amount of production technologies of simplifying, for the producer saves a large amount of cost payouts.
Simplify production procedure, reduce the fraction defective in technique.
Shield effectiveness, through detecting, can be obtained than current technique and improve shield effectiveness more than minimum 5db.
Can to electromagnetic shielding film, to carry out the adjustment of shielding properties according to user to shield effectiveness requirement just, need to not increase again operation in order to improve shielding properties, to solve the cost that the producer pays in order shielding.In the time of need to carrying out better shield effectiveness to wire rod for future, the shield effectiveness that directly can adjust electromagnetic shielding film directly promotes the shielding character of wire rod.
At present traditional wire rod shielding operation, on shielding problem, has approached the limit, be not easy to promote shield effectiveness, and electromagnetic shielding film also possesses the hoisting power that approaches more than 1 times (50db 97db) on shield effectiveness again.
Improve conventional machining process, the specific (special) requirements of the following new product of cooperation that more can be suitable.
The characteristic that coordinates EMI product, more can effectively solve performance loss and the decline that existing signal wire rod causes in packing, transportation, external environment and using method, has prevented that the variable factor after finished product from occurring.
Because substitution material EMI characteristic is better than existing shielding material (aluminium/tinfoil paper), can improve in production process because the quality problems such as shutdown that the fracture of aluminium/tinfoil paper causes, replacing, joint more can reduce the technological requirement because of the disposable uninterrupted production of need, significantly reduce damage expense processed.As grid line (shielding conductor class), take 305M as manner of packing, in 305M, above-mentioned item can not occur, otherwise the production rice number producing is defective products entirely.
As known by the technical knowledge, the present invention can realize by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.Change within the scope of the present invention all or within being equal to scope of the present invention is all included in the invention.
