Abstract
The utility model discloses a kind of high insulated shield cable, teflon insulation layer, screen and sheath that described high insulated shield cable comprises wire and is wrapped in successively from inside to outside wire; Described screen is composite shielding layer or metal tube screen.By screen, be set to the shield effectiveness that composite shielding layer or metal tube screen can improve screen greatly, polytetrafluoroethylmaterial material insulating barrier can improve insulation effect.
Description
Technical field
The utility model relates to a kind of high insulated shield cable.
Background technology
As everyone knows, 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, more and more higher to the requirement of cable, should guarantee that it has good transmission performance and mechanical performance, require again simple in structure, with low cost.But the signal shielding effect of existing coaxial cable is poor, insulation property also have much room for improvement simultaneously, and prior art is badly in need of a kind of signal shielding and the good high insulated shield cable of insulation effect.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of signal shielding and insulation effect good high insulated shield cable.
For achieving the above object, the technical solution of the utility model has been to provide a kind of high insulated shield cable, teflon insulation layer, screen and sheath that described high insulated shield cable comprises wire and is wrapped in successively from inside to outside wire; Described screen is composite shielding layer or metal tube screen.By screen, be set to the shield effectiveness that composite shielding layer or metal tube screen can improve screen greatly, polytetrafluoroethylmaterial material insulating barrier can improve insulation effect.
As preferably, described composite shielding layer comprises two-layer above tinned wird braid, and it is outside that described two-layer above tinned wird braid is closely wrapped in teflon insulation layer successively.Multi-layer braided layer like this arranges and can improve shield effectiveness.
As preferably, between described two-layer above tinned wird braid and teflon insulation layer, be provided with curtain.Such design can further improve shield effectiveness.
As preferably, between described two-layer above tinned wird braid, be also provided with curtain.Such design can further improve shield effectiveness.
As preferably, described curtain is pure copper foil, pure aluminum foil or aluminum-plastic composite membrane.Such design can further improve shield effectiveness.
As preferably, described metal tube screen is seamless helical corrugation copper pipe or seamless helical corrugation aluminum pipe.Such design is the further optimization to scheme.
As preferably, described conductor is by 7 stranded forming of silver-coated copper wire.Such design is the further optimization to scheme.
As preferably, described teflon insulation layer is perfluoroethylene-propylene teflon insulation layer, and described sheath is perfluoroethylene-propylene sheath.Such design is the further optimization to scheme.
As preferably, described wire overall diameter is: 0.24 ~ 0.306mm; Described teflon insulation layer overall diameter is: 0.7 ~ 0.905mm; Described screen overall diameter is: 1.13 ~ 1.46mm; Described sheath overall diameter is: 1.3 ~ 1.78mm.
Advantage of the present utility model and beneficial effect are: by screen, be set to the shield effectiveness that composite shielding layer or metal tube screen can improve screen greatly, polytetrafluoroethylmaterial material insulating barrier can improve insulation effect.
