Abstract
The utility model discloses a star-quad-stranding shielding data-transmission cable, and the cable comprises four conductive cable cores. The outer side of each conductive cable core is wrapped by an FEP insulating layer in a pressing manner. A tubular filling core is disposed among the four conductive cable cores wrapped by the FEP insulating layers. The four conductive cable cores wrapped by the FEP insulating layers and the tubular filling core forms a cable core in a stranded cable structure. The cable core is wrapped by a composite shielding layer which is sequentially wrapped by a polyester film and an elastomer sheath. On the basis of guaranteeing high impedance (120 Ohm), a small comprehensive dielectric constant, a small attenuation constant, a small size, a light weight and a moderate price, the cable improves the mechanical and physical performances of a product. The localization of the product completely solves the problem of project stranding caused by foreign blockade on techniques and embargo, so the cable meets the demands of the aerospace aviation field and other related fields.
Description
Technical field
The utility model relates to a kind of data cable.The star quad stranding shadow data transmission cable that particularly relates to a kind of perfluoroethylene-propylene insulating elastomer sheath.
Background technology
The star quad stranding of applying in Aero-Space and computer realm at present covers logarithmic data transmission cable product, mostly dependence on import.The application of star quad stranding shadow data transmission cable product, can, by the difference of transmitting (reception) frequency, realize many signals of line high-speed transfer.
The star quad stranding shadow data transmission cable using at present, because adopting wire and blank pipe, it fills star quad stranding combining structure, therefore under the condition of specific high characteristic impedance (120 Ω), exist that complex dielectric constant is large, attenuation constant is large, volume is large, the quality problem such as heavily.And imported product exists that price is high, delivery cycle is long, easily by problems such as blockade on new techniques and embargoes.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of high impedance, complex dielectric constant is little, attenuation constant is little star quad stranding shadow data transmission cable are provided.
The technical scheme that the utility model adopts is: a kind of star quad stranding shadow data transmission cable, include conductor wire core, described conductor wire core is provided with four, the outside of each root conductor wire core extrudes one deck perfluoroethylene-propylene insulating barrier, between described four conductor wire cores that are enclosed with perfluoroethylene-propylene insulating barrier, be provided with a tubulose filled core, described four conductor wire cores that are enclosed with perfluoroethylene-propylene insulating barrier and tubulose filled core form the cable core of stranded cable structure jointly, the wrapped one deck composite shielding layer in outside of the cable core of described stranded cable structure, the outside of described composite shielding layer is enclosed with polyester film and elastic body jacket successively.
Described conductor wire core is to consist of silver-plated copper stranded wire core.
Described tubulose filled core is the empty cylinder structure consisting of thermostable fluorine material.
Described composite shielding layer is to consist of the polyester/aluminium laminated film setting gradually from the inside to the outside and tinned wird woven shield.
A kind of star quad stranding shadow data transmission cable of the present utility model, guaranteeing on high impedance (120 Ω), complex dielectric constant is little, attenuation constant is little, volume is little, quality is light, moderate basis, improved the mechanical and physical performance of product, and thoroughly solve because foreign technology blocks and embargo causes the problems such as project is stranded with the production domesticization of this product, meet the needs of the association areas such as space flight and aviation.
