Description
Technical field
The present invention relates to coaxial cable technology field, be specifically related to super soft aluminum outer conductor radio frequency coaxial cable.
Background technology
China is manufacturing nation and the demand state of radio frequency coaxial-cable maximum in the world. In recent years, developing rapidly of China Mobile's industry, it is greatly promoted the market demand to radio frequency coaxial-cable. Meanwhile, along with the requirement of signal transmission quality is improved constantly by downstream industry, China is also more and more higher for radio frequency coaxial-cable requirement in softness and low-loss.
Radio frequency coaxial-cable generally comprises inner wire, insulating barrier, outer conductor and sheath, and its softness is by the material of each several part and structures shape thereof. And low-loss depends primarily on foam degrees, owing in insulating barrier, air proportion is more high, its foam degrees is more good, and in cable, the loss of signal is more little. Meanwhile, during cable bend, insulating barrier is difficult to provide enough support, surface wrinkling when causing cable bend, bending section cross section flatten, the alignment of inner wire and outer conductor is destroyed, and will also result in the loss of signal.
Therefore, the development of cable internal structure often gets down to the balance found between bending property and low-loss quality, finds the equilibrium point of the best so that the low-loss quality of the super soft flexible performance of cable pitch and signal.
The Chinese utility model patent that Authorization Notice No. is CN201466188U discloses a kind of super soft radio frequency coaxial-cable, it is characterised in that outer conductor and inner wire have employed spiral corrugated structure. Though this structure can increase the softness of cable, but could not reach low-loss effect.
