Abstract
The utility model discloses a coaxial cable structure capable of strengthening shielding effects. A composite cable comprises an aluminum core and a filling rope, the sectional area of the filling rope is 0.50-1.0mm<2>, a copper layer is wrapped outside the aluminum core and wraps an insulating foaming layer with a plurality of holes, and the volume of the plurality of holes occupies 50% of that of the insulating foaming layer. A polyester belt layer wraps the surface of the insulating foaming layer and the filling rope, an aluminum foil layer wraps the polyester belt layer, an inflaming-retarding layer is wrapped on the surface of the aluminum foil layer, and a shielding layer weaved by a plurality of aluminum-magnesium alloy wires is arranged between the inflaming-retarding layer and the aluminum foil layer. The coaxial cable structure can reduce influence on the cable from high-frequency electromagnetic radiation and condenser coupling and can reduce dielectric constant of insulating media.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of coaxial cable structure that strengthens shield effectiveness.
Background technology
Along with the development and progress of information technology, for accelerating transmission rate and providing information transmission quality that increasingly high demand has been arranged.In the case, not only will satisfy the requirement of transmission rate to the requirement of coaxial cable, the q&r of its transmission more and more comes into one's own.Existing coaxial cable constitutes elementary cell (coaxial to) by the cylindrical metal conductor of two concentrics, mutually insulated earlier, again by single or a plurality of coaxial cables to forming.
Coaxial cable divides from purposes can be divided into base band coaxial cable and BBC(broadband coaxial cable) (being network coaxial cable and video coaxial cable).Coaxial cable divides two types of 50 Ω base band cables and 75 Ω broadband cables.The base band cable divides thin coaxial cable and thick coaxial cable again.The base band cable only is used for Digital Transmission, and data transfer rate can reach 10Mbps.
Broadband cable is the standard of using in the CATV system, and it both can use the analog signal of frequency division multiplex to send, but also transmission of digital signals.The price of coaxial cable is more expensive than twisted-pair feeder, but its interference free performance is stronger than twisted-pair feeder.When connecting more equipment and message capacity, needs can select coaxial cable when quite big.But the anti-high frequency electromagnetic radiation of above-mentioned coaxial cable and capacity coupled poor-performing, and the dielectric constant of coaxial cable is bigger.
Summary of the invention
The utility model provides a kind of coaxial cable structure that strengthens shield effectiveness, and this coaxial cable structure can reduce the influence to cable of high frequency electromagnetic radiation and capacitive coupling, and can reduce the dielectric constant of dielectric.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of coaxial cable structure that strengthens shield effectiveness, said recombination line cable wrap is drawn together aluminium core and gasket for packing;
The sectional area of said gasket for packing is 0.50～1.0 mm
2
Said aluminium core coats a bronze medal layer, and this copper layer is coated with to have as if an insulation foaming layer in cavity, and this is if an empty volume accounts for 50% of said insulation foaming layer volume;
One polyester belt coats said insulation foaming layer and gasket for packing surface;
One aluminium foil layer coats said polyester belt;
One flame-retardant layer is coated on said aluminium foil layer outer surface;
Be provided with the screen that forms by several aluminum-magnesium alloy wire braidings between said flame-retardant layer and the aluminium foil layer.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said aluminium core diameter is 1.0 ± 0.005 mm.
2. in the such scheme, said aluminium foil layer is two-sided aluminium foil layer.
3. in the such scheme, said gasket for packing area of section is 0.50～1.0mm
2
Because the technique scheme utilization, the utility model compared with prior art has advantage:
The utility model strengthens the coaxial cable structure of shield effectiveness; This coaxial cable structure can reduce the influence to cable of high frequency electromagnetic radiation and capacitive coupling; And reduce the dielectric constant of insulating barrier; And then reach the purpose that reduces electric capacity, reduces single line line footpath, saves material, reduces cost, thereby the dielectric constant of reduction dielectric improves the transmission performance of material, has confirmed best foam degrees parameter in the production process.
