Abstract
The invention relates to the technical field of cables and particularly relates to a gigabit three-network convergent coaxial cable. The coaxial cable comprises a copper core, wherein the outside surface of the copper core is wrapped with a conductor protective layer, an inert gas physical foaming layer, a foaming protective layer, a shielding layer and an outer sheath layer in sequence from inside to outside; the foaming protective layer can enable the inert gas physical foaming layer to be foamed more evenly, so that the inert gas physical foaming layer can have stable transmission performance and fast transmission speed without interfering a transmission signal of a cable core and can realize gigabit transmission speed and long-distance transmission with stable signal; and besides, the conductor protective layer can prevent the air from entering in the cable and oxidizing the cable core, thus the transmission performance and service life of the cable core can be ensured.
Description
Technical field:
The present invention relates to the cable technology field, relating in particular to a kind of current collection sight line, telephone wire, grid line function is the gigabit level integration of three networks coaxial cable of one.
Background technology:
Cable is the material that is used for electric power, communication and associated transport purposes, comprises that mainly bare wire, electromagnetic wire and electrical equipment and electrical are with insulated electric conductor, power cable, telecommunication cable, optical cable etc.Along with the arrival of information age, the conveying capacity of information becomes explosive growth, and as the effective means of big capacity, long Distance Transmission, cable and optical cable obtain number of applications.Present coaxial cable mainly is made up of copper core, inert gas physical blowing layer, screen and exodermis, and this cable transmission performance is unstable, and copper core signal receives external disturbance easily; Transmission speed is low; Jitter, transmission range is short, is difficult to reach the transmission speed of gigabit level.
Summary of the invention:
The object of the invention is exactly the deficiency that exists to prior art and provide that a kind of transmission performance is stable, the fast gigabit level integration of three networks coaxial cable of transmission speed.
To achieve these goals, the technical scheme of the present invention's employing is:
Gigabit level integration of three networks coaxial cable includes the copper core, and the copper core outer surface is coated with conductor overcoat, inert gas physical blowing layer, foaming overcoat, screen and exodermis from the inside to the outside successively.
Said conductor overcoat is a low density polyethylene layer.
Said inert gas physical blowing layer is a nitrogen physical blowing layer.
Said foaming overcoat is a high-density polyethylene layer.
Said screen is aluminum pipe or is coated on foaming overcoat outer surface by aluminium strip and forms.
Said exodermis is a low density polyethylene layer.
Beneficial effect of the present invention is: the present invention includes the copper core, the copper core outer surface is coated with conductor overcoat, inert gas physical blowing layer, foaming overcoat, screen and exodermis from the inside to the outside successively, and the foaming overcoat can make inert gas physical blowing layer physical blowing more even; Transmission performance is stable; Can not disturb copper core transmission signals, transmission speed is fast, can realize the transmission speed of gigabit level; Signal stabilization, transmission range is long; And the conductor overcoat can prevent that the air entering from causing the oxidation of copper core, guarantees the transmission performance and the useful life of copper core.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described; See shown in Figure 1; Gigabit level integration of three networks coaxial cable, it includes copper core 1, and copper core 1 outer surface is coated with conductor overcoat 2, inert gas physical blowing layer 3, foaming overcoat 4, screen 5 and exodermis 6 from the inside to the outside successively.
Inert gas physical blowing layer 3 is high nitrogen physical blowing layer, uniform in foaming.
Foaming overcoat 4 is a high-density polyethylene layer, can make inert gas physical blowing layer 3 physical blowing more even, and transmission performance is stable; Can not disturb copper core 1 transmission signals, transmission speed is fast, can realize the transmission speed of gigabit level; Signal stabilization, transmission range is long.
Exodermis 6 is a low density polyethylene layer, has performances such as wear-resistant preferably, anti-oxidant, insulation.
Certainly, the above only is preferred embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, characteristic and principle change or modify, includes in patent claim of the present invention.
