Abstract
The invention relates to a coaxial cable, which comprises a core wire, an insulating layer coating the core wire, and a sheath coating the insulating layer. The coaxial cable is further provided with a nano metal layer arranged between the sheath and the insulating layer. The coaxial cable adopts the nano metal layer formed by deposition to replace an aluminum foil layer and a braided layer in the existing coaxial cable, saves a great amount of metal raw materials, simplifies working processes, improves the production efficiency of the coaxial cable, and has greatly improved electromagnetic shielding effect than the existing coaxial cable.
Description
Technical field
The present invention relates to a kind of coaxial cable with screen.
Background technology
The existing coaxial cable for signal connection is generally by heart yearn, insulating barrier, aluminium foil layer, braid and sheath carry out Overmolded layer by layer forming, aluminium foil layer and braid serve as screen, when there is electromagnetic interference in the external world, Electromagnetic Field is after screen, vortex flow can be produced in screen inside, due to the existence of vortex flow, so screen to generate electromagnetic waves and then act on equally on heart yearn and produce vortex flow on heart yearn, heart yearn is caused to make the electric current exported increase when transmitting and controlling electric current, that is the electromagnetic interference in the external world only weakens by existing coaxial cable, the impact on the heart yearn in Signal transmissions can not be eliminated, and the preparation of aluminium foil layer and braid shaping be to expend time in the most in the production process of coaxial cable and artificial operation.
So, be necessary that a kind of new coaxial cable of design is to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide the coaxial cable that a kind of capability of electromagnetic shielding is excellent.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of coaxial cable, and it comprises heart yearn, the insulating barrier of cladding core wire and the sheath of coated insulation layer, and described coaxial cable is also provided with the nano metal layer between sheath and insulating barrier.
As a further improvement on the present invention, described nano metal layer is that depositing nano metal forms after jacket inner wall or insulating barrier outer wall are corroded.
As a further improvement on the present invention, described nano metal layer thickness is within the scope of 1-2 μm.
As a further improvement on the present invention, described nano metal layer adopts at least one in gold, silver, copper, tin, iron to be prepared from.
As a further improvement on the present invention, described heart yearn comprises multiple conducting wires, and described multiple conducting wires comprises an earth lead.
The present invention adopts the nano metal layer of deposition to replace aluminium foil layer in existing coaxial cable and braid, not only save a large amount of raw material metals, and simplify in operation, improve the production efficiency of coaxial cable, on effectiveness, more existing coaxial cable has larger lifting.
Accompanying drawing explanation
Fig. 1 is the sectional stereogram of coaxial cable of the present invention.
Fig. 2 is the profile view of coaxial cable of the present invention.
Embodiment
Refer to shown in Fig. 1,2, coaxial cable 100 of the present invention comprises heart yearn 1, the insulating barrier 2 of cladding core wire 1 and the sheath 3 of coated insulation layer 2, comprises a nano metal layer 4 between sheath 3 and insulating barrier 2.
Heart yearn 1 comprises multiple conducting wires 5, and multiple conducting wires 5 comprises an earth lead 6.
Nano metal layer 4 is formed by the rear depositing nano metal of chemical reagent corrosion at sheath 3 inwall or insulating barrier 2 outer wall, is understandable that, by other forms of corrosions corrosion sheath 3 inwall or insulating barrier 2 outer wall, also all in protection scope of the present invention.
Nano metal layer 4 thickness, 1-2 μm of scope, can save a large amount of raw material metals.
Nano metal layer 4 adopts at least one in gold, silver, copper, tin, iron to be prepared from.
This invention is suitable for multiple flat cable or circular cable, and its capacitive reactance is 110pF/M, and characteristic impedance is 95 Ω/M.
Coaxial cable of the present invention has the following advantages.
1. solve the copper wire short circuit that existing coaxial cable often occurs in the preparation, the difficult problem flown in the processing such as silk.
2. achieve the technique that mould molding cannot complete.
3., in high frequency data transfer, characteristic impedance obtains the control of 100%.
4. processing is simple, does not need to drop into a large amount of manpower for pretreatment procedure.
5. can meet the designing requirement of cable industry 4.0.
The present invention adopts the nano metal layer 4 of deposition to replace aluminium foil layer in existing coaxial cable and braid, not only save a large amount of raw material metals, and simplify in operation, improve the production efficiency of coaxial cable, on effectiveness, more existing coaxial cable has larger lifting.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
