The utility model discloses a metal nanoparticles layer that the deposit formed replaces aluminium foil layer and weaving layer among the present coaxial cable, not only saves a large amount of metal raw and other materials, simplifies in the process in addition, has improved coaxial cable's production efficiency, and present coaxial cable has great promotion in the electromagnetic shield effect.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is the coaxial cable providing a kind of capability of electromagnetic shielding excellent.
For realizing aforementioned object, the utility model 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 further improvement of the utility model, described nano metal layer is that depositing nano metal forms after jacket inner wall or insulating barrier outer wall are corroded.
As further improvement of the utility model, described nano metal layer thickness is within the scope of 1-2 μm.
As further improvement of the utility model, described nano metal layer adopts at least one in gold, silver, copper, tin, iron to be prepared from.
As further improvement of the utility model, described heart yearn comprises multiple conducting wires, and described multiple conducting wires comprises an earth lead.
The utility model 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 the utility model coaxial cable.
Fig. 2 is the profile view of the utility model coaxial cable.
Embodiment
Refer to shown in Fig. 1,2, the utility model coaxial cable 100 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; be understandable that; by other forms of corrosions corrosion sheath 3 inwall or insulating barrier 2 outer wall, also all in protection range of the present utility model.
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 utility model is suitable for multiple flat cable or circular cable, and its capacitive reactance is 110pF/M, and characteristic impedance is 95 Ω/M.
The utility model coaxial cable 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 utility model 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 preferred implementation of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
