Abstract
The utility model relates to a solid polytetrafluoroethylene insulation radio frequency coaxial cable, comprising a four-layer structure, including an electric-conduction core, an inner insulating layer, a weaving layer and an outer insulating layer from inwards to outwards sequentially; the solid polytetrafluoroethylene insulation radio frequency coaxial cable is characterized in that: the weaving layer is weaved by nickel-plating silver-copper wires, the inner insulating layer is coated on the electric-conduction core, the weaving layer is wrapped outside the inner insulating layer, and the outer insulating layer is coated on the weaving layer; the material of the inner insulating layer is polytetrafluoroethylene, the material of the outer insulating layer is fluorinated ethylene propylene copolymers; in the utility model, the silver-plating copper wires of the weaving layer are changed into nickel-plating silver-copper wires, expensive silver is saved and the production cost is greatly reduced; the increased nickel ions can well coat and bind the copper ions, and the silver ions are more stable on the weaving layer, the transmission property of the cable is improved, the product has competitiveness and has wide market prospect in the 3G communication field.
Description
Technical field
The utility model relates to a kind of electric wire, specifically relates 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, belongs 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 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.
The utility model content
Be to solve the deficiencies in the prior art, the purpose of this utility model is the solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable that provides a kind of price comparatively cheap to improve transmission performance.
For achieving the above object, the utility model is to realize by following technical scheme:
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, on the inner insulating layer coated with conductive 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 inner insulating layer is a polytetrafluoroethylene.
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.
The beneficial effects of the utility model are: the utility model changes braid the braiding of 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, makes silver ion more stable on braid simultaneously, has improved the transmission characteristic of cable, makes product more competitive, has vast market prospect in the 3G communications field.
Description of drawings
Fig. 1 is the structural representation of solid-core polyfluortetraethyleinsulating insulating radio frequency coaxial cable of the present utility model.
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 utility model.
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 utility model 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 utility model 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, 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, cut off the interference of outer signals, guarantee transmission quality lead core 1.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 utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection range of the present utility model.
