Abstract
The utility model discloses a kind of naked copper wire insulation cable, described naked copper wire insulation cable comprises inner wire and is wrapped in successively teflon insulation layer, outer conductor layer and the sheath of inner wire; Described inner wire forms by bare copper wire is stranded.By inner wire, be set to bare copper wire and can reduce impedance, improve the transmission performance of cable.Stranded mode can further strengthen the flexibility of cable simultaneously, and polytetrafluoroethylmaterial material insulating barrier can improve insulation effect.
Description
Technical field
The utility model relates to a kind of naked copper wire insulation cable.
Background technology
As everyone knows, radio frequency coaxial-cable is indispensable element in range radio communication system and electronic equipment, at aspects such as radio communication and broadcast, TV, radar, navigation, computer and instrument, applies widely.Growing along with the communication technology, requirement to radio frequency cable is more and more higher, should guarantee that it has good transmission performance and mechanical performance, require lower impedance also to require cable to have certain flexibility, the insulation property between internal and external conductor also need to improve simultaneously simultaneously.Prior art is badly in need of good, the flexible better and good cable of insulation effect of a kind of electric conductivity.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of electric conductivity good, the flexible better and good naked copper wire insulation cable of insulation effect.
For achieving the above object, the technical solution of the utility model has been to provide a kind of naked copper wire insulation cable, and described naked copper wire insulation cable comprises inner wire and is wrapped in successively teflon insulation layer, outer conductor layer and the sheath of inner wire; Described inner wire forms by bare copper wire is stranded.By inner wire, be set to bare copper wire and can reduce impedance, improve the transmission performance of cable.Stranded mode can further strengthen the flexibility of cable simultaneously, and polytetrafluoroethylmaterial material insulating barrier can improve insulation effect.
As preferably, institute's inner wire is by 7 stranded forming of bare copper wire, described inner wire overall diameter size 0.24 ~ 0.306mm.Such design is the further optimization to scheme.
As preferably, described outer conductor layer is bare copper wire braid, described outer conductor layer overall diameter size 0.92 ~ 1.13mm.Such design is the further optimization to scheme.
As preferably, described teflon insulation layer overall diameter size is 0.7 ~ 0.905mm.Such design is the further optimization to scheme.
As preferably, described teflon insulation layer is to be provided with air insulating layer in solid layer or teflon insulation layer.Such design is the further abundant and optimization to scheme.
As preferably, described sheath is perfluoroethylene-propylene sheath, and described sheath overall diameter scope is 1.13 ~ 1.37mm; Between described teflon insulation layer and organization level, be provided with copper foil layer.Such design is the further optimization to scheme, improves shield effectiveness.
As preferably, in described teflon insulation layer, be provided with air insulating layer, inside and outside interior teflon insulation layer and the outer teflon insulation layer of being respectively of described air insulating layer, is provided with isolation pad in described air insulating layer.Such design is the further optimization to scheme, improves insulation effect.
As preferably, described isolation pad is screw-type support sheet, described screw-type support sheet along cable axially around interior teflon insulation layer outer wall spiral around, described screw-type support sheet respectively with interior teflon insulation layer and outer teflon insulation layer fixed bonding or be wholely set.Such design is the further abundant and optimization to scheme, improves insulation effect.
Advantage of the present utility model and beneficial effect are: by inner wire, be set to bare copper wire and can reduce impedance, improve the transmission performance of cable.Stranded mode can further strengthen the flexibility of cable simultaneously, and polytetrafluoroethylmaterial material insulating barrier can improve insulation effect.
