Abstract
The utility model relates to a cable, especially to a bare copper wire polytetrafluoroethylene coaxial cable, comprising an inner conductor (1), an insulating layer (3), a shielding layer (4) and a sheath layer (5). The inner conductor (1) employs a bare copper wire, the insulating layer (3) is formed by piling up polytetrafluoroethylene, and an anti-oxidation layer (2) is arranged between the inner conductor (1) and the insulating layer (3) and is formed by extrusion molding fluorinated ethylene propylene. According to the bare copper wire polytetrafluoroethylene coaxial cable of the utility model, the inner conductor employs the bare copper wire, and a layer of ultrathin fluorinated ethylene propylene is arranged on the outside of the bare copper wire in advance, so that the surface of the bare copper wire can be prevented from generating oxidation when a polytetrafluoroethylene insulating layer is formed subsequently, and accordingly, the production cost is reduced substantially.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of bare copper wire teflon coaxial cable.Be mainly used in communication, electronics tracking, warning, electronic countermeasures, navigation, high frequency connecting line, testing equipment and Military Electronic Equipment and the relevant civilian microwave equipment such as draw.Belong to the telecommunication cable technical field.
Background technology
Coaxial cable is the cable general name of the interior signal transmission of radio-frequency band or energy.Main as radio transmission or receiving equipment feeder and the machine intraconnections of various communication, electronic equipment or interconnect line.Conventional teflon coaxial cable is comprised of inner wire heart yearn, insulating barrier, screen and restrictive coating, because teflon coaxial cable need to pass through the sintering furnace sintering when forming the teflon insulation layer, because temperature is higher in the sintering furnace, if copper line surface can produce oxidation when the inner wire heart yearn adopted bare copper wire, this will produce harmful effect to the performance of coaxial cable, therefore the inner wire heart yearn adopts silver-coated copper wire usually at present, but has so just increased the production cost of cable.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of production cost lower bare copper wire teflon coaxial cable.
The purpose of this utility model is achieved in that a kind of bare copper wire teflon coaxial cable, it comprises inner wire, insulating barrier, screen and restrictive coating, described inner wire adopts bare copper wire, described insulating barrier adopts polytetrafluoroethylene to push and forms, be provided with antioxidation coating between described inner wire and the insulating barrier, described antioxidation coating adopts the perfluoroethylene-propylene extrusion molding to form.
Compared with prior art, the utlity model has following beneficial effect:
A kind of bare copper wire teflon coaxial cable of the utility model, its inner wire adopts naked copper single line or bare copper stranded wire, it arranges the ultra-thin perfluoroethylene-propylene of one deck in advance outside bare copper wire, can prevent follow-up bare copper wire surface generation oxidation when forming the teflon insulation layer, therefore greatly reduce production cost.
