High definition multimedia interface (HDMI) linear material

Abstract

The invention discloses a high definition multimedia interface (HDMI) linear material, comprising a core wire, at least one external paired core wire and a core wire jacket, wherein, the inner part of the core wire is provided with inlayer aluminum mylar foil, an internal paired core wire, inner cascading water earth wires and anti-electromagnetic interference earth wires, and the outer part of the core wire is coated with outer-layer aluminum mylar foil, anti-electromagnetic interference braided-layer core wires and the core wire jacket; the inner paired core wire and the external paired core wire are in a round layered structure which comprises a conductor layer and an insulating layer arranged outside the conductor layer; the specification of the manufacturing material of the conductor layer is 36AWG (American wire gauge) of tinned cooper wires; the core wire jacket is made of Teflon; and the external diameter of the core wire jacket is 3.6+ / -0.15 millimeters. The linear material provided by the invention not only has smaller wire material outer diameter, but also has better welding performance.

Description

technical field [0001] The invention relates to a wire, in particular to an HDMI wire, which is particularly suitable for use on small electronic products. Background technique [0002] With the advent of the high-definition digital era, HDMI (High Definition Multmedia Interface, high-resolution multimedia digital transmission interface) cable is a high-frequency cable for high-definition digital video signal transmission, mainly used in TVs, DVDs, computers and other products. At present, the outer diameter of standard HDMI cables on the market is more than 4 mm. In view of the current trend of miniaturization of electronic products, especially the mobile phone industry needs to use ultra-small cables to directly transmit images to TV / projection equipment, and the outer diameters of existing products are all More than 4 mm, so the existing products cannot meet the existing market demand. At the same time, with the reduction of the outer diameter of the wire rod, problems s...
