Abstract
The utility model discloses a data bus cable, which adopts conductors which are formed by stranding 19 silver-plated copper wires respectively. The surfaces of the stranded conductors are subjected to rolling processing, so that the surfaces of the stranded conductors are smooth and rounded, an insulating wire core is formed by coating a layer of polytef insulating layer outside each conductor in a melt extrusion manner, the two insulating wire cores and two filling strips are stranded to form a cable core, the surface of the cable core is provided with a cable shielding layer which is formed by a metal net woven by using silver-plated copper wires, and a layer of meltable polytef sheath layer is coated outside the shielding layer in a melt extrusion manner. By adopting special materials, the data bus cable has the advantages of high temperature resistance, high mechanical strength, small outer diameter, high utilization frequency and the like, and is suitable for data system connecting wires inside various kinds of combat vehicles.
Description
Technical field
The utility model relates to a kind of cable, is specifically applicable to a kind of data bus cable of various battlebus built-in systems.
Background technology
At present, on market, the data/address bus of extensive use is mainly to adopt cross-linking type ethylene-tetrafluoroethylene copolymer to make to insulate and sheath, such cable is due to the lightweight aerospace field that is used to, yet such cable is owing to considering that the weight that reduces cable causes product cost higher (crosslinked ethene-tetrafluoroethylene copolymer material price is 1800 yuan/kilogram) for use in aviation, except aerospace field, the military comprises battlebus at ground installation, same a large amount of these class cables that use of the occasions such as ground command system, and its to cable weight without specific (special) requirements, therefore caused the waste of resource.
Utility model content
The purpose of this utility model is to provide a kind of data bus cable, for shortcoming in the technology of background, has adopted new material, and this cable, on the basis of original cable, has improved the mechanical strength of hookup wire, has reduced the outside diameter of cable, has reduced cable cost simultaneously.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of data bus cable, it comprises restrictive coating, cable shield, it is characterized in that: in described cable shield, be provided with cable core, in described cable core, be provided with 2 insulated wire cores, 2 packings, described insulated wire cores includes insulating barrier, conductor, and described conductor is by 19 stranded forming of silver-gilt copper wire.
Described insulating barrier is polytetrafluoroethylene.
Described cable shield adopts silver-plated copper silk screen.
Described restrictive coating is Meltability polytetrafluorethyletubular.
Its operation principle is as follows: by 19
silver-coated copper wire is twisted into conductor, to conductor lines surface, adopt mould to roll and make silver-coated copper wire rounding more, make cable resistance more stable, reduced cable transmission decay, at conductor, extrude one deck teflon insulation layer outward and form insulated wire cores, it is material that insulating barrier has adopted nonpolar polytetrafluoroethylene, this material is that cable when used under high frequency, impedance, decay, the electrical quantitys such as electric capacity are more stable, in the situation that guaranteeing impedance, reduced the external diameter of cable, cable distribution has been saved to space, adopt that Meltability polytetrafluorethyletubular is solid extrudes round shape bar as packing, by two insulated wire cores, add two stranded cable cores that form of packing left-hand, in the braiding of cable core external application silver-gilt copper wire, form cable shield, outermost layer is coated one deck Meltability polytetrafluorethyletubular as restrictive coating by the mode melt extruding, adopted silver-coated copper wire as screen, and polytetrafluoroethylene is as insulation and sheath material, make cable working temperature bring up to 250 ℃.
In sum, the utility model advantage is as follows: this utility model has been owing to having adopted special material, makes it have that heatproof is high, mechanical strength is large, external diameter is little, the high feature of frequency of utilization, is applicable to various battlebus built-in system connection lines.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, silver-gilt copper wire; 2, conductor; 3, insulating barrier; 4, insulated wire cores; 5, packing; 6, cable core; 7, cable shield; 8, restrictive coating.
