Abstract

The invention relates to a cable which comprises at least one pair of differential signal conductors, an insulator which wraps each pair of differential signal conductors and an outer layer which wraps the insulator. A metal plating layer is formed at the surface of the insulator. Aluminum foil and copper foil can be replaced by the metal plating layer which is provided with a signal shielding function. The shape of the metal shielding layer is completely consistent with that of the insulator such that the distances from the differential signal conductors to the metal plating layer are consistent in each direction, the characteristic impedance consistency of the differential signal conductors is effectively ensured, the signal attenuation and loss of high frequency transmission are reduced, and the quality of high frequency signal transmission is improved.

Description

technical field [0001] The invention relates to a cable, in particular to a cable for transmitting high-frequency signals. Background technique [0002] With the development and popularization of electronic technology products, cables, as a tool for transmitting signals, are widely used in the connection of consumer electronics, home appliances, instruments and other electronic equipment. In the prior art, in order to meet the needs of high-frequency signal transmission, cables are generally provided with several pairs of differential signal lines. Each differential signal line usually includes a conductor, an insulator that wraps the conductor from the inside to the outside, a signal shielding layer, and a braided layer. , Outer cover, shielding layer is aluminum foil or copper foil. The distance between the conductor and the shielding layer in each pair of differential signal lines is difficult to maintain a high degree of consistency in all directions, and it is difficul...
