Along with the fast development of electronics and information industry, signal-transmitting cable is proposed higher requirement, transmission cable develops to directions such as broadband, low-loss, low standing wave, high-frequencies.And, therefore in the communication technology, obtain increasingly extensive application because coaxial cable can be supported the high-bandwidth signals transmission of long distance.Coaxial cable generally adopts polytetrafluoroethylene as insulating layer material, but the dielectric constant of polytetrafluoroethylmaterial material is bigger, and usually about 2.2, so signal can produce decay significantly in transmission course, reduced the efficiency of transmission of coaxial cable.Particularly serious during the problems referred to above high-frequency transmission, because the dielectric constant of insulating barrier can increase when high-frequency transmission, and signal attenuation also increases thereupon.
Can know that to sum up existing coaxial cable obviously exists inconvenience and defective on reality is used, so be necessary to improve.
The utility model content
To above-mentioned defective, the purpose of the utility model is to provide a kind of coaxial cable, and it can reduce the dielectric constant of insulating barrier, and then has reduced the signal transmission attenuation, and can improve the through-put power of cable, has reduced manufacturing cost simultaneously.
To achieve these goals, the utility model provides a kind of coaxial cable, and said coaxial cable includes inner wire, insulating barrier, outer conductor and sheath from inside to outside, and said insulating barrier is provided with some spaces.
According to the described coaxial cable of the utility model, said insulating barrier is processed by polytetrafluoroethylene, and said insulating barrier is coated on the said inner wire with one heart.
According to the described coaxial cable of the utility model, said some spaces are vertically even and continuous distribution on said insulating barrier.
According to the described coaxial cable of the utility model, the dielectric constant of said insulating barrier is 1.3～1.6.
According to the described coaxial cable of the utility model, said inner wire is processed by silver-gilt copper wire.
According to the described coaxial cable of the utility model, said outer conductor is processed by tinned wird, and said outer conductor is coated on the said insulating barrier with one heart.
According to the described coaxial cable of the utility model, said sheath is processed by perfluoroethylene-propylene or low smoke halogen-free flame-retardant polyolefin, and said sheath is coated on the said outer conductor with one heart.
According to the described coaxial cable of the utility model, said coaxial cable is high frequency half a gentle radio frequency coaxial-cable.
The utility model is through being provided with some spaces on insulating barrier; Said some spaces are vertically even and continuous distribution on insulating barrier preferably; To form the insulating barrier of dielectric and air unification; This insulation layer structure can reduce the dielectric constant of insulating barrier, and then has reduced the signal transmission attenuation, and improves the through-put power of cable; And,, therefore can reduce the material usage of about 40% insulating barrier, thereby reduce manufacturing cost because insulating barrier is provided with the space.The utility model is particularly useful for being the transmission of the signal between high-frequency apparatus such as mobile communication, tracking, warning, radar, electronic countermeasures, satellite navigation, employed high frequency half flexible coaxial radio frequency cable.
