Abstract

The utility model relates to a high-temperature and irradiation resistant data bus cable used for transmitting multiple compound signals. The data bus cable comprises insulated conductors, filling cores, shielding layers and sheaths, wherein each insulated conductor is formed by extruding an insulating layer outside an inner conductor, the two insulated conductors and the two filling cores are arranged symmetrically and stranded to be bundles respectively, and the three-layer structured shielding layers and the sheaths are arranged outside the insulated conductors and the filling cores in sequence. The data bus cable has the benefits of high-temperature resistance, low temperature resistance, light weight, excellent flame retardance and electromagnetic compatibility, so that the temperature of a product can reach 200 DEG C, a long-term operating temperature can reach minus 100 DEG C, the weight can be reduced by about 20 percent compared with the FEP material, the oxygen index can reach 40, and the double-layer knitted structure with anti-electromagnetic composite films arranged therein greatly improves the anti-electromagnetic interference capability of the product and ensures the reliable transmission of the signals.

Description

Data bus cable
Technical field
The utility model relates to a kind of cable, particularly a kind of high temperature resistant, radiotolerant data bus cable that is used for field multichannel composite signal transmission usefulness such as Aero-Space, electronics.
Background technology
Along with the develop rapidly of Aeronautics and Astronautics and electronics industry and defence engineering, the cable of signal transmission usefulness is proposed higher requirement, cable develops to directions such as miniaturization, in light weight, high temperature resistant, anti-electromagnetic interference.General data cable is third rare with polyethylene foamed, polyethylene, perfluoroethylene, polytetrafluoroethylene is as insulating material, with the normal temperature material as packing material, these materials are all poor aspect fire-retardant, intensity, signal attenuation index and high and low temperature resistance, can not satisfy the job requirement of complete machine.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of high temperature resistant, low temperature resistant, in light weight, data bus cable that antijamming capability is strong.
The utility model for achieving the above object, the technical scheme that is adopted is: a kind of data bus cable, the conductor that included extrudes insulated electric conductor, filled core, screen and the sheath that a layer insulating constitutes outward, it is characterized in that: two described insulated electric conductors, two described filled cores are symmetrical arranged stranded bunchy respectively, are provided with the screen and the sheath of three-decker outside it successively.
The beneficial effects of the utility model are: insulating barrier, filled core, sheath all adopt insulation cross-linking radiation X-ETFE material, and the high temperature resistant heatproof of product that can make reaches 200 ℃; The low temperature resistant temperature that works long hours can reach-100 ℃.In light weight: the density of this kind material is littler than the density of common fluoroplastics, is 1.7g/cm 3The weight of the product that reduces greatly can be than adopting the FEP material to reduce about 20% on the weight.Good flame resistance: have very high fire resistance, oxygen index can reach 40.Electro Magnetic Compatibility: adopted add in the double braid anti-electromagnetism composite membrane structure, the design of three layers of shielding construction can improve the anti-electromagnetic interference capability of product greatly, the shielding attenuation of product can reach 100dB.Stability: between insulation, added round filled core, made product electrical property (electric capacity and impedance decay etc.) stable, guaranteed the reliable transmission of signal.Anti-irradiation: the X-ETFE material of employing has very high anti-irradiation ability, and radiation-resistant property can reach 1 * 10 8Mrad.
