Abstract
The utility model relates to a novel electrical transmission wire which comprises a core wire and an insulating layer. An EVA wrapping layer which is arranged on the surface of the core wire wraps thecore wire therein, and the PVC insulating layer which is arranged on the outer surface of the EVA layer wraps the EVA layer together with the core wire in the EVA layer therein, so as to form the electrical transmission wire. By combining the PVC insulating property and the good EVA electrical-physical property, the novel electrical transmission wire has the characteristics of good toughness, good tension resisting property, difficult pull-apart, good interference resisting property and enhanced sensitivity. Meanwhile, adhesion cannot be incurred between an insulating skin at the outer layerand an inner core, so as to prolong the service life of the transmission wire. Therefore, the novel electrical transmission wire is a new generation product used for the electronic industry.
Description
Technical field
The utility model relates to a kind of used in electronic industry electric transmission line, and particularly a kind of electrical signal transmission line is the innovation to traditional electrical signal transmission line, belongs to the electronic industrial products technical field.
Background technology
Along with the fast development of electronics industry, the electrical signal transmission line that uses on the electric equipment products is also more and more, its kind is also different because of different instructions for uses with structure, the shielding action of existing requirement band, there is requirement that anti-bending is arranged again, numerous.The electric transmission line of used in electronic industry in the past generally is to constitute electric transmission line coating with lacquer PVC plastic insulating layer on the core outer wrapping, or clads plastic layer on the enamel-cover core, superscribes the PVC insulating barrier at outer surface again.The mentioned kind transmission line is owing to the manufacturing process maturation, and the improvement of material property generally can both meet the requirement of electrical signal transmission line or light current transmission.But this class transmission line stretching resistance is poor, easily pull apart, and sensitivity shortcoming, shielding action are also bad, and particularly its insulation sheath and inner core can produce conglutination reaction in the use, influence the useful life of electric transmission line.
Summary of the invention
Shortcoming at above-mentioned electric transmission line, the utility model provides a kind of novel electric transmission line, it is provided with the good EVA material integument of electrical property on the transmission line heart yearn, outsourcing PVC insulating barrier again, thereby reach the electric transmission line good toughness, strong, anti-interference strong, the increase sensitivity of pull resistance, the purpose that prolongs transmission line.
Technical solution adopted in the utility model:
A kind of novel electric transmission line comprises heart yearn, insulating barrier, and insulating barrier wraps heart yearn, it is characterized in that on the surface of heart yearn EVA material integument being set, and the EVA integument with the heart yearn parcel within it; Outer surface at the EVA integument is provided with the PVC insulating barrier, and the heart yearn that the PVC insulating barrier will be enclosed with the EVA integument is wrapped in and wherein constitutes this electric transmission line.
Described heart yearn is enamelled wire or copper cash or aluminum steel, and enamelled wire can be sub-thread or multiply enamelled wire.
Described EVA material integument can replace with the integument of PE material or EVA material and PE compound.
EVA (ethene-vinyl acetate copolymer) film dissolves at a certain temperature, and after temperature reduced, eva film solidified, electric physical property excellence.
The utility model electric transmission line is achieved in that parcel EVA material integument on the heart yearn of enamelled wire earlier, forms the transmission line body of EVA integument, at the external PVC plastic insulating layer that superscribes again of EVA parcel layer line, promptly constitutes this electric transmission line then.
Advantage of the present utility model:
Compare with traditional electrical signal transmission line, the utility model electric transmission line superscribes the EVA layer at the heart yearn skin, physics that EVA is good and excellent electrical characteristics make this transmission line good toughness, and stretching resistance is strong, be difficult for pulling apart, antijamming capability is strong, and shielding action is good, increases sensitivity, the insulating barrier crust and the inner core of transmission line can not produce pinning phenomenon simultaneously, prolong the useful life of transmission line.
Description of drawings
Fig. 1 is the utility model transmission line structure schematic diagram;
Fig. 2 is the utility model transmission line sectional view.
Embodiment
The contrast accompanying drawing specifies its structure.
In Fig. 1 and Fig. 2, be provided with EVA integument 2 on the surface of heart yearn 1, the EVA integument is wrapped in heart yearn wherein, establishes PVC insulating barrier 3 again at the outer surface of EVA parcel then, and the PVC insulating barrier together is wrapped in PVC insulating barrier in together with the EVA integument of heart yearn heart yearn and constitutes this electric transmission line.The nexine heart yearn of this transmission line, intermediate layer are the EVA layer, and skin is a PVC igelite insulating barrier.The electric physical features that the EVA layer is good in conjunction with PVC insulating barrier crust, is further enhanced this electric transmission line electromechanical performance.
