Abstract
The utility model relates to a high temperature resistance data transmission composite cable which is suitable for transmitting data signals and providing electric energy in a long distance among devices of an aeronautic and astronautic system, a ground vehicle system and a spaceship system, and has a function of towing a device at the meantime. The composite cable comprises insulation wires formed by extruding layers of insulating layers outside conductors, filling cores, branch shielding layers, reinforcing cores, a main shielding layer I, a main shielding layer II and a sheath. Two insulation wires and two filling cores are intertwisted together, and a layer of the branch shielding layer is winded and coated over them to form a data transmission wire; two data transmission wires and two reinforcing cores are intertwisted to form a cable, and the outside of the cable is sequentially winded and coated with a layer of the main shielding layer I, knitted with a layer of the main shielding layer II and extruded with a layer of the sheath. The composite cable has the advantages of high temperature resistance, low temperature resistance, stable impedance, small attenuation, chemical attack resistance and large tensile strength.
Description
Technical field
The utility model relates to field of cables, particularly a kind of high temperature resistant transfer of data composite cable.This cable is suitable between the equipment of aerospace system, surface car system and Ship System the transmission of long-range data signal and electric energy is provided, and possesses the function of haulage gear simultaneously.
Background technology
Existing common signal shielding cable generally only possesses the data-signal transfer function, and the electric energy of providing and drag function are not provided, and anti-outside electromagnetic interference ability, thereby is unfavorable for long range signals transmission and power delivery.In general composite cable, power line adopts the stranded insulation form that extrudes again in addition, the whole cable external diameter is increased and rounding not.
Summary of the invention
Deficiency in view of the prior art existence, the invention provides a kind of high temperature resistant transfer of data composite cable that adopts new construction, new material, this cable has impedance stabilization, it is little, high temperature resistant, low temperature resistant to decay, tensile strength is large, anti-outside electromagnetic interference ability reaches by force the characteristics such as resistance to chemical attack, be suitable between the equipment of aerospace system, surface car system and Ship System the transmission of long-range data signal and electric energy is provided, possessing the function of haulage gear simultaneously.
The utility model for achieving the above object, the technical scheme adopted is: a kind of high temperature resistant transfer of data composite cable, it is characterized in that: be included in conductor and extrude the insulated wire that a layer insulating forms outward, filled core, sub-shield, strengthening core, total screen I, total screen II, sheath, after two described insulated wires and two filled cores are stranded at wrapped one deck sub-shield composition data transmission line, two described data lines and two strengthening core twisted synthesizing cables, total screen I of wrapped one deck successively outside it, the total screen II of braiding one deck, extrude one deck sheath.
The beneficial effects of the utility model are:
(1) high temperature resistant, low temperature resistant: insulating barrier, filled core and sheath adopt the perfluoroethylene-propylene material, and shielding adopts the materials such as silver-coated copper wire, guarantee that the composite cable heatproof reaches-65 ℃～200 ℃.
Impedance stabilization, decay little: the silver-coated copper wire conductor extrudes insulated wire that one deck perfluoroethylene-propylene insulating barrier forms and perfluoroethylene-propylene filled core, polyester aluminium laminated film sub-shield outward, and structure and perfluoroethylene-propylene material that this kind dosed filled core guarantee that composite cable has impedance stabilization, little characteristics decay.
(3) resistance to chemical attack: insulating barrier and sheath adopt the perfluoroethylene-propylene material, guarantee that composite cable has the characteristics of resistance to chemical attack.
(4) anti-outside electromagnetic interference ability is strong: composite cable adopts polyester aluminium laminated film sub-shield, the total screen I of polyester aluminium laminated film and the total screen II of silver-coated copper wire, and three shieldings have strengthened the anti-outside electromagnetic interference ability of composite cable.
(5) tensile strength is large: used the aramid fiber strengthening core in composite cable, the pulling force of aramid fiber material is very big, has increased the tensile strength of composite cable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
