Description
Technical field
The utility model relates to a kind of power cord cable, more specifically to a kind of small bore data integration shielded type cable.
Background technology
Along with the development of modern information technologies Highgrade integration, the communication cable has entered the every field of wire communication at present, but communication cable place device interior exists various interference to perplex people's actual use always.Shielded type cable is low because of the loss that it has, transmission frequency bandwidth, little, lightweight, the anti-electromagnetic interference of capacity large volume, be difficult for the advantages such as cross-talk, enjoys the insider to favor, and develops very fast.The more electric assembly system of integrated form of various combination screen unit class kinds is used more and more widely, and supporting with it electric wire has also been proposed new shielding requirements.Similar shielded type cable one is that polymeric barrier layer materials is more single in the market, and count is lower; The 2nd, the mounting means of shielded type cable mainly adds the wiring of screen with single conductor, the waste wiring space, and the use amount of increase cable also can cause the phase mutual interference between cable; The 3rd, conventional shielded type cable easily produces the imperfect earth phenomenon, and shielding itself may become a radiation source during improper use, generates the current earthing loop, or receives ambient radiation, and the data cable of Xiang Xiangling sends harmful interference.The 4th, tensile strength a little less than, can't normally use in the occasion that environment is abominable; The 5th, conventional serviceability temperature is that-15 ℃～+ 70 ℃, fire protecting performance are relatively poor, and under the different regional climate conditions, the scope of application is limited.
The utility model content
In order to overcome the defective of above-mentioned prior art, it is a kind of by the textural association mode that changes cable, the shield effectiveness that improves cable that the utility model provides, phase mutual interference when remedying the concentrated use of classical signal cable, a kind of small bore data integration shielded type cable that loss is large, capability of resistance to radiation is low.
The utility model is realized by following scheme, a kind of small bore data integration shielded type cable, mainly comprise conductor layer 1, insulating barrier 2, sub-shield 3, aluminium platinum screen 4, internal shield 5, restrictive coating 6, outer shielding layer 7, wherein: described conductor layer 1 be by the identical soft round silver-gilt copper wire of some diameters by concentric type and in succession each level form so that different directions is stranded;
Described insulating barrier 2 insulating barriers adopt the polytetrafluoro film divide three layers wrapped around conductor layer 1;
Described sub-shield 3 is to be that the 0.08mm silver-gilt copper wire is woven in insulating barrier 2 skins by filament diameter;
Described internal shield 5 closely is woven in aluminium platinum screen 4 peripheries for tinned copper wire, adds respectively that at the positive and negative conducting surface of aluminium platinum a diameter is the zinc-plated drainage thread of 0.41mm;
Described restrictive coating 6 is the TPU elastomers all around that closely are coated on tinned copper wire internal shield 5;
Described outer shielding layer 7 is that the employing filament diameter is that the 0.15mm tin plated steel wire is woven in TPU elastic body jacket layer 6 skin.
The utlity model has in sum following beneficial effect: the conductor layer core can be single core, can be two cores, four-core also, and geometry is fixed, and stability is high, but very little on the curvature impact of cable; Adopted respectively silver-plated silk woven shield; aluminium platinum screen; tin plated wire woven shield and tin plated steel wire braiding protective layer; has the multiple shield protection; aluminium platinum composite band composite sheath; not only played the effect of electromagnetic shielding but also played radially moistureproof effect; screen had both played the externally effect of emission of electromagnetic wave that suppresses; can be used as again the passage of short circuit current; can play the protective effect of neutral core; especially many in the signal transmission kind; a little less than the signal; require in the low comprehensive wiring of loss; shield effectiveness is with the obvious advantage, therefore is widely used in Aero-Space; radar; battlebus; instrument and meter; the more electric assembly system of integrated form of the combination screen unit class kind such as communication equipment.
