TECHNICAL FIELD
[0001] The present application relates to the technical field of coaxial lines for new energy vehicle navigation, in particular to a coaxial line based on new energy vehicle navigation. BACKGROUND
[0002] Coaxial line is a common signal transmission line, the copper core in the center is used for transmitting high level, which is covered by insulating material, and the outside of the insulating material is a cylindrical metal layer coaxial with the copper core, which transmits low level and simultaneously plays a shielding role. The structure of the coaxial line is, from the outside to the inside, in turn, a sheath, an outer conductor as a shielding layer, an insulating medium and an inner conductor part.
