First, about the insulated electric conductor of the first embodiment of the present utility model, illustrate with reference to Fig. 1.

As it is shown in figure 1, the insulated electric conductor 1100 of an embodiment of the present utility model includes conductor 1101 Low-k magnetic masking layer 1102 with the surrounding being formed at conductor 1101.

Conductor 1101 is made up of the silver-coated copper wire etc. that electric conductivity is high.Thereby, it is possible to make the surface of conductor 1101 AC impedance reduce, it is possible to press down transmitting, with high-frequency signal, the harmful effect of Kelvin effect accompanied System is in Min..

Low-k magnetic masking layer 1102 is that (the low dielectric in inner side is normal with the low-k resin bed of two-layer Number resin beds 1104 and outside low-k resin bed 1105) sandwich the magnetic bisque 1103 of a layer Formed, play magnetic masking layer as the impact alleviating the external magnetic field becoming extraneous noise producing cause Effect and the effect as insulating coating.

This insulated electric conductor 1100 manufactures through following operation: cladding (example around conductor 1101 Such as substantial extrusion cladding (Japanese: fill extrusion be coated to)) low-k resin and formed uncured low First operation of dielectric constant resin bed (inner side uncured low-k resin bed)；Make magnetic powder It is attached to the surrounding of the uncured low-k resin bed in inner side and forms the second of magnetic bisque 1103 Operation；Cladding (such as enriching extrusion cladding) low-k resin around magnetic bisque 1103 Form further the of uncured low-k resin bed (outside uncured low-k resin bed) Three operations；And, make the uncured low-k resin bed in inner side be solidified to form inner side low-k Resin bed 1104, simultaneously make outside uncured low-k resin bed be solidified to form outside low dielectric normal 4th operation of number resin bed 1105.

That is: manufacturing insulated electric conductor 1100 when, with the rate of delivery of regulation, conductor 1101 is connected Continue and send, around conductor 1101, sequentially form inner side uncured low-k resin bed, magnetic Gonosome bisque 1103 and outside uncured low-k resin bed, hereafter, makes inner side uncured low simultaneously It is normal that dielectric constant resin bed and outside uncured low-k resin bed is solidified to form the low dielectric in inner side Number resin bed 1104 and outside low-k resin bed 1105, it is possible to be readily formed low dielectric normal Number magnetic masking layer 1102.

The thickness of magnetic bisque 1103 is about 5 μm～10 μm, preferably uses nanocrystal soft magnetic material (Nanocrystalline soft magnetic material, the Off ァ イ of such as Hitachi Metal Co., Ltd.

4th embodiment

About magnetic (property) shielded cable of the 4th embodiment of the present utility model, say with reference to Fig. 6 Bright.

As shown in Figure 6, the electromagnetic shielding cable 3100 of the 4th embodiment includes: center conductor 3101；Bag Overlay on the insulating barrier 3102 of the surrounding of center conductor 3101；It is coated on the magnetic shield of the surrounding of insulating barrier 3102 Layer 3103；And it is coated on the outside clad 3104 of the surrounding of magnetic masking layer 3103.

Wherein, magnetic masking layer 3103 is with film layer (inner side film layer 3106 and the outside film layer of two-layer 3107) sandwiching the magnetic bisque 3105 of a layer and formed, playing to alleviate to self becomes extraneous noise The impact of the external magnetic field of reason, play to alleviate to other parts becomes the inside of extraneous noise reason simultaneously The effect of the leakage in magnetic field.

This electromagnetic shielding cable 3100 manufactures through following operation: by applying coating by center conductor 3101 and the surrounding of cable 3108 that constitutes of insulating barrier 3102 and form uncured film layer (inner side be uncured Film layer) the first operation；Magnetic powder is made to be attached to the surrounding of the uncured film layer in inner side and form magnetic Second operation of gonosome bisque 3105；By applying coating further shape around magnetic bisque 3105 Become the 3rd operation of uncured film layer (the uncured film layer in outside)；And make the uncured film in inner side Layer is solidified to form inner side film layer 3106, makes the uncured film layer in outside be solidified to form outside painting simultaneously 4th operation of film layer 3107.

Center conductor 3101 is preferably formed by the high copper of electric conductivity, copper alloy etc., insulating barrier 3102 preferably by Insulating properties height, the polyvinyl resin that dielectric constant is low, fluororesin etc. are formed.Thereby, it is possible to alleviate use Electromagnetic shielding cable 3100 transmits the transmission loss during signal of telecommunication, is using electromagnetic shielding cable 3100 to transmit simultaneously High Speed Transfer can be carried out with high frequency when of the signal of telecommunication.

Outside clad 3104 is to be formed by the fluororesin etc. that scratch resistance is contour, plays as preventing magnetic cup Cover the effect of the sheath of the damage etc. of cable 3100.

The thickness of magnetic bisque 3105 is about 50 μm, preferably by nanocrystal soft magnetic material equimagnetic The material (Off ァ イ Application メ ッ ト (registered trade mark) of such as Hitachi Metal Co., Ltd.) that shielding is high Deng formation.Thus, both sought the thin footpath of electromagnetic shielding cable 3100, again can be to electromagnetic shielding cable 3100 Give electromagnetic shielding performance.

The thickness of inner side film layer 3106 and this two-layer of outside film layer 3107 is about 20 μm～50 μm, excellent Select by extensibility, flexible high ultraviolet curing during high to the tack of magnetic powder time uncured, solidification Type cold coating is (such as polyurethane acrylate resin coating, Epocryl coating, organic Silicon resin coating, organic silicon acrylic ester cold coating or polyester acrylate resin coating), thermosetting Property cold coating (such as polyurethane resin coating) etc. formed.Thus, electromagnetic shielding cable 3100 can be maintained Flexibility, resistance to bend(ing), electromagnetic shielding performance can be given to electromagnetic shielding cable 3100 again.

Here, inner side film layer 3106 must be by coating shape high to the tack of magnetic powder time uncured Becoming, outside film layer 3107 is the most necessarily by coating shape high to the tack of magnetic powder time uncured Become.This is because, at inner side film layer 3106 not by painting high to the tack of magnetic powder time uncured In the case of material is formed, the amount of the magnetic powder being attached to the uncured film layer in inner side can tail off, it is possible to right Electromagnetic shielding cable 3100 give electromagnetic shielding performance be likely to decrease, even in outside film layer 3107 not by In the case of the coating that the tack of magnetic powder is high being formed time uncured, it is attached to the uncured painting in inner side The amount of the magnetic powder of film layer also will not become, thus it is possible to the magnetic shield that electromagnetic shielding cable 3100 is given Property can not reduce.
