Abstract
The utility model relates to a flexible RF (Radio Frequency) cable with low attenuation and high shielding property. The flexible RF cable adopts the structure that a half-raw polytetrafluoroethylene insulating layer, a tinned copper wire woven and integrally tinned shielding layer and a sheath are sequentially arranged outside a silver-plated copper wire inner conductor. The flexible RF cable has the characteristics that the half-raw polytetrafluoroethylene insulating layer ensures lower attenuation of the cable, the tinned copper wire woven and integrally tinned shielding layer ensures that the cable has a better shielding property and better flexibility; and meanwhile, owing to the design, the weight and the cost of the cable are both lowered.
Description
Technical field
The utility model relates to the high shielding properties soft radio-frequency cable of a kind of low decay, is widely used in the systems such as mobile communication, microwave measurement, space flight and aviation, navigation.
Background technology
Insulating barrier use polytetrafluoroethylene has plenty of at the radio frequency coaxial-cable that generally uses in China at present, and screen uses silver-coated copper wire, and such radio frequency cable serviceability temperature is higher, but decay and shielding properties are relatively poor; Have plenty of shielding and use the tinned wird integral tin, this advantages of good shielding performance but fade performance is relatively poor; Have plenty of insulation and use the low-density polytetrafluoroethylene, shielding uses silver-plated copper strips to add the silver-coated copper wire braiding, and such radio frequency cable cost is higher, better performances.
Summary of the invention
In view of the deficiency that existing radio frequency cable exists, the utility model provides a kind of low decay high shielding properties soft radio-frequency cable.
The utility model for achieving the above object.The technical scheme of taking is: the high shielding properties soft radio-frequency cable of a kind of low decay is characterized in that: be included in the silver-coated copper wire inside conductor and be provided with successively the half-mature teflon insulation layer of one deck, tinned wird braiding and integral tin screen, sheath formation outward.
Characteristics of the present utility model are: half-mature teflon insulation layer has guaranteed that this cable has lower decay; Tinned wird braiding and integral tin screen have guaranteed that this cable has had preferably shielding properties, and have preferably flexibility; Simultaneously this design has reduced weight and the cost of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, the high shielding properties soft radio-frequency cable of a kind of low decay, being included in the outer half-mature teflon insulation layer 2 of one deck, tinned wird braiding and integral tin outer conductor 3, the sheath 4(sheath material of being provided with successively of silver-coated copper wire inner wire 1 can be according to materials such as the different choice polyvinyl chloride of environment for use and cost, fast light hot polymerization ethene, perfluoroethylene-propylene, fire retardant polyolefin, flame retardant polyurethanes) coaxial cable that consists of.
