Abstract
The invention relates to a solid-core polyfluortetraethylene insulating radio frequency coaxial cable, which comprises a structure of four layers from inside to outside: conductor wire core, inside insulating layer, braid layer and outside insulating layer. The invention is characterized in that the braid layer is braided by nickel silver-plated copper wires, the inside insulating layer is frothed polyfluortetraethylene coated on the conductor wire core, the braid layer is coated outside the inside insulating layer, and the outside insulating layer is coated on the braid layer. In the invention, silver-plated copper wires are replaced by nickel silver-plated copper wires, thus saving expensive silver and greatly lowering production cost; the added nickel ions can coat and bundle the copper ions well and stabilize the silver ions, thus improving transmission property of the cable; the polyfluortetraethylene of the inside insulating layer is frothed, thus reducing use of raw material, saving polyfluortetraethylene, improving transmission property of the polyfluortetraethylene, having higher product competence and wide market prospect in 3G communication market.
Description
Technical field
The present invention relates to a kind of electric wire, specifically relate to a kind of solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable that is used for radio communication, broadcasting and relevant electronic equipment transmitting radio frequency signal, belong to the cable processing technique field.
Background technology
Gaining the name and its structurally associated of coaxial cable (COARIAL CABLE).Coaxial cable also is one of modal transmission medium in the local area network (LAN), it is used for the pair of conductors of the information of transmitting is that outer conductor (or braid) according to one deck drum type brake is enclosed within inner wire (a thin core) outside, the structure of isolating mutually with insulating material between two conductors is made, the center of circle of outer contact and central shaft heart yearn is on same axle center, so be called coaxial cable, why coaxial cable is designed to like this, also is in order to prevent the transmission of external electromagnetic wave interference abnormal signal.Coaxial cable generally is used for transmitting radio frequency signal, for example is used for transmitting television signals, vision signal, broadcast singal, mobile telephone signal etc., on the line of equipment such as measuring and controlling equipment, removable instrument, uses coaxial cable also morely.
Along with developing rapidly of 3G communication, very fast to the demand growth of coaxial cable, the performance requirement to coaxial cable is also more and more higher simultaneously.The outer conductor of present coaxial cable generally all is the copper wire braid, outside at copper wire is silver-plated, because the price valency height of silver, therefore cause the price of outer conductor and whole coaxial cable higher, and developing rapidly along with communication industry, the fast development of especially present 3G communication, the user demand of coaxial cable also significantly increases, the high cost that uses enterprise that also increased of cable price.In addition, silver ion is also bad to the constraint and the covered effect of copper ion, causes the silver ion instability, has influenced transmission performance.Simultaneously, the inner insulating layer of existing coaxial cable generally all is to adopt solid polytetrafluoroethylmaterial material, and solid polytetrafluoroethylene is waste material not only, and is also influential to the transmission characteristic of signal.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide the comparatively cheap solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable of a kind of price, improve transmission performance.
The solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable that another object of the present invention is to provide a kind of economical with materials, improves transmission characteristic.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable, comprise 4 layers of structure, be followed successively by from inside to outside: conductor wire core, inner insulating layer, braid and external insulation layer, it is characterized in that described braid is formed by the braiding of nickel plating silver-bearing copper silk, inner insulating layer is the polytetrafluoroethylene of foaming, be coated on the conductor wire core, braid is wrapped in the outside of inner insulating layer, and external insulation layer is coated on the braid.
Aforesaid solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable, the material that it is characterized in that described external insulation layer is the perfluoroethylene-propylene copolymer.
Aforesaid solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable is characterized in that described conductor wire core is a nickel plating silver-bearing copper silk.
The invention has the beneficial effects as follows: the present invention changes braid and conductor wire core into nickel plating silver-bearing copper silk by silver-gilt copper wire, has saved expensive silver, greatly reduces production cost; And the nickel ion that increases can coat copper ion, fetter better, make silver ion more stable on braid and conductor wire core simultaneously, improved the transmission characteristic of cable, made product more competitive, had boundless market prospects in the present 3G communications field.With the foaming of the polytetrafluoroethylene of inner insulating layer, reduced raw-material use simultaneously, saved a large amount of polytetrafluoroethylene, and the polytetrafluoroethylene of foaming also improved transmission characteristic, made the performance of product better.
Description of drawings
Fig. 1 is the structural representation of solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable of the present invention.
The implication of main mark is among the figure:
1, conductor wire core, 2, inner insulating layer, 3, braid, 4, external insulation layer.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
Fig. 1 is the structural representation of solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable of the present invention.
Present 3G Communication Development is rapid, and is also more and more higher to the demand and the performance requirement of coaxial cable, and the present invention is promptly at this situation and development and Design.
As shown in the figure, solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable of the present invention comprises conductor wire core 1, inner insulating layer 2, braid 3 and external insulation layer 4, conductor wire core 1 is positioned at the inside, outside at conductor wire core 1 coats inner insulating layer 2, and inner insulating layer 2 adopts the polytetrafluoroethylene (PTFE) of foaming.To the PTFE foaming, can save a large amount of raw materials, reduce the cost of product greatly, simultaneously, adopt the PTFE of foaming can also use the air transfer that wherein comprises, to transmission characteristic, improve a lot.Braid 3 is formed by the braiding of nickel plating silver-bearing copper silk, is coated on the outside of inner insulating layer 2, as the electro-magnetic screen layer of cable, cuts off the interference of outer signals to lead core 1, guarantees transmission quality.In the coated outside of braid 3 one deck external insulation layer 4, external insulation layer 4 is insulated layer outward for slim, protects whole cable, prevents the wearing and tearing of braid 3.
Inner insulating layer 2 adopts polytetrafluoroethylene (PTFE) to make, and plays the effect that supports and insulate, and the material that external insulation layer 4 adopts is perfluoroethylene-propylene copolymer (FEP), improves the protection effect.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
