Abstract
Provided is a signal transmission cable. The signal transmission cable includes: at least one pair of signal wires for transmitting a group of differential electronic signals, a first metal shielding film coated on a part of a surface of the at least one pair of signal wires; a second metal shielding film opposite to the first metal shielding film and coated on a part of a surface of the at least one pair of signal wires; and a first insulation film by which the first metal shielding film and the second metal shielding film are secured to the surface of the pair of signal wires. The first metal shielding film and the second metal shielding film are collectively coated on the entire surface of the at least one pair of signal wires, and the second metal shielding film partially overlaps the first metal shielding film.
Claims16
A signal transmission cable, comprising:
- a pair of signal wires, which is used for transmitting a group of differential electronic signals;
- a first metal shielding film, which is coated on a first part of a surface of the pair of signal wires;
- a second metal shielding film, which is opposite to the first metal shielding film and is coated on a second part of the surface of the pair of signal wires;
- and
- a first insulation film, which is used for securing the first metal shielding film and the second metal shielding film to the surface of the pair of signal wires,
- wherein the first metal shielding film and the second metal shielding film collectively are coated on the entire surface of the pair of signal wires, and the second metal shielding film partially overlaps the first metal shielding film on a periphery of the pair of signal wires,
- wherein two ends of the first metal shielding film each have a first edge, two ends of the second metal shielding film each have a second edge, a horizontal axis line connects axes of the pair of signal wires, two perpendicular axis lines pass through the respective axes of the pair of signal wires and are perpendicular to the horizontal axis line, an angle between each of the horizontal axis line and the perpendicular axis lines and a line connecting a terminal of the first edge to the axis of one of the pair of signal wires adjacent to the first edge is approximately 45 degrees, and an angle between each of the horizontal axis line and the perpendicular axis line and a line connecting a terminal of the second edge to the axis of one of the pair of signal wires adjacent to the second edge is approximately 45 degrees.
