Bending-resistant and anti-faking cable

Abstract

The invention discloses a bending-resistant and anti-faking cable. The bending-resistant and anti-faking cable comprises a conductor which is spirally twisted by bare copper single wires, and an insulating layer, a braiding layer braided by the bare copper wires and a sheath which are arranged on the conductor in a coating manner from inside to outside in sequence, wherein the conductor is spirally twisted by seven bare copper single wires; the cable is provided with a bending section; and a bending-resistant thickened layer is arranged on the sheath on the exterior of the bending section. By adoption of the scheme of the invention, the flexibility of the copper material can be brought into full play while the various electrical performances are kept unchanged, so that the bending fatigue resistance is improved by multiple times; and by setting the bending-resistant thickened layer at the bending position (bending section) of the cable, the bending radius when the cable is bent can be improved, and damage to the wire caused by an overlarge bending angle can be lowered.

Description

technical field [0001] The invention relates to a bending-resistant anti-counterfeit cable. Background technique [0002] As we all know, radio frequency coaxial cables are indispensable components in various radio communication systems and electronic equipment, and are widely used in wireless communication and broadcasting, television, radar, navigation, computers and instruments. With the development of communication technology, the requirements for radio frequency cables are getting higher and higher. It is necessary to ensure that they have good transmission performance and excellent mechanical properties. At present, customers only need the bending fatigue resistance of coaxial cables The requirements are getting higher and higher. For example, the connection line between the display screen and the host computer used in a notebook computer needs strong resistance to bending fatigue. When the user repeatedly turns on the computer display screen, the connecting cable will...

With the development of communication technology, the requirements for radio frequency cables are getting higher and higher. It is necessary to ensure that they have good transmission performance and excellent mechanical properties. At present, customers only need the bending fatigue resistance of coaxial cables The requirements are getting higher and higher. For example, the connection line between the display screen and the host computer used in a notebook computer needs strong resistance to bending fatigue. When the user repeatedly turns on the computer display screen, the connecting cable will also be bent repeatedly. If Insufficient bending fatigue resistance of the cable can lead to display failure
