Abstract
The utility model discloses a polyethylene coaxial radio frequency cable comprising an internal conductor, an internal sheath, a first external conductor, a second external conductor and an external sheath. The internal conductor is matchedly arranged in the internal sheath, the first external conductor is coated on the internal sheath, the second external conductor is coated on the first external conductor, and the external sheath is coated on the second external conductor. According to a manner mentioned above, the polyethylene coaxial radio frequency cable has improved anti-interference capability, uniform impedance, stable transmission performance and stable mechanical property.
Description
Technical field
The utility model relates to the cable field, particularly relates to a kind of polythene coaxial RF cable.
Background technology
Radio frequency cable is the cable of electromagnetic energy in the transmission radio-frequency region, radio frequency cable is indispensable element in range radio communication system and electronic equipment, uses widely at aspects such as radio communication and broadcasting, TV, radar, navigation, computer and instrument.Wherein most widely used is coaxial cable, mainly as the machine intraconnections of the feeder of radio transmission or receiving equipment and various communication, electronic equipment or interconnect line.Existing coaxial radio frequency cable, its basic structure from inside to outside is made of coaxial inner wire, insulating barrier, braid, outer conductor and restrictive coating successively.Although the progress of modern cables manufacturing technology has improved the antijamming capability of cable greatly, adapted to the transmission demand of high-speed data communication and LAN (Local Area Network).But modern coaxial radio frequency cable, foam degrees is increasing, and foamed insulation adopts blown with carbon dioxide, and the foamed insulation solid material reduces, strength decreased, insulator is easily impaired, thus transmission quality and efficient lower, loss is large, shielding and anti-interference are poor, especially the telecommunication cable electrical property is subject to the shortcomings such as natural environment and climate condition influence, makes its scope of application enjoy restriction, can not use at high-frequency range.Along with the development of national defence weapon equipment and microwave communication, and the demand of civilian intelligent microwave instrument, telecommunication transmission is more and more higher to the requirement of radio frequency cable attenuation and voltage standing wave ratio.
The utility model content
The technical problem that the utility model mainly solves is to provide a kind of polythene coaxial RF cable, can improve antijamming capability, and impedance is even, transmission performance and stable mechanical performance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of polythene coaxial RF cable is provided, comprise: inner wire, inner sheath, the first outer conductor, the second outer conductor and oversheath, described inner wire is equipped with in inner sheath, described the first outer conductor is coated on inner sheath, described the second outer conductor is coated on the first outer conductor, and described oversheath is coated on the second outer conductor.
In preferred embodiment of the utility model, described the first outer conductor is aluminium foil.Described the second outer conductor comprises the east line braiding of multiply metal and reticulates braid.
In preferred embodiment of the utility model, described inner sheath is solid polyethylene insulation sheath, and the external diameter of described inner sheath is 4.6mm.
In preferred embodiment of the utility model, described inner wire is naked copper, and the diameter of described inner wire is 0.75mm.
In preferred embodiment of the utility model, described oversheath is the polyethylene insulation sheath, and the external diameter of described oversheath is 7.0mm.
The beneficial effects of the utility model are: the utility model polythene coaxial RF cable, can improve antijamming capability, and impedance is even, transmission performance and stable mechanical performance.
