Problems solved by technology

However, with the development of computer technology, the data transmission speed of computer hard disks and motherboards and other electronic products is getting faster and faster, and the transmission frequency is getting higher and higher. Impedance is very important to the integrity of high-speed digital signals. It is generally required to be controlled between 80Ω and 100Ω. Traditional wire settings can no longer meet the requirements.

Abstract

Disclosed is a data transmission cable, comprising a first conducting wire (11) and a second conducting wire (12) which are arranged adjacent to each other. The first conducting wire (11) and the second conducting wire (12) respectively have a conductor (13) located at a central position and a coating layer (14, 15) coating the periphery of the conductor. An outer diameter of the conductor (13) is within the range of the American wire gauge from 28 to 31. When the outer diameter of the conductor (13) uses 28 AWG, centre-to-centre spacing between the first conducting wire (11) and the second conducting wire (12) is set as being from 0.51 mm to 0.75 mm. When the outer diameter of the conductor (13) uses 29 AWG, the centre-to-centre spacing between the first conducting wire (11) and the second conducting wire (12) is set as being from 0.38 mm to 0.75 mm. When the outer diameter of the conductor (13) uses 30 AWG to 31 AWG, the centre-to-centre spacing between the first conducting wire (11) and the second conducting wire (12) is set as being from 0.38 mm to 0.62 mm.

Description

technical field [0001] The invention relates to a data transmission cable, in particular to a data transmission cable that meets requirements and has better high-frequency performance. Background technique [0002] In the 3C industry, transmission cables can be used as a medium for electrical connection between two electronic devices and can stably perform expected signal transmission operations. Therefore, transmission cables are widely used in various electronic devices. Among them, transmission cables connected to interfaces such as USB, HDMI, DVI, and Displayport have high transmission rates, long distances, and high quality, and are popular with the public, and the number of uses is increasing day by day. These transmission cables have a plurality of metal wires inside, and the metal wires are covered with an insulating layer to isolate the short circuit between the metal signal wires. However, with the development of computer technology, the data transmission speed of...
