Abstract

The invention discloses a high-definition multimedia interface (HDMI) wire. The high-definition multimedia interface (HDMI) wire is composed of twisted pair core wires, a magnetic powder layer and a plastic layer. Seen from the cross section of the high-definition multimedia interface (HDMI) wire, the magnetic powder layer is coated on the twisted pair core wires, and the plastic layer is coated on the magnetic powder layer. A device for preparing the high-definition multimedia interface (HDMI) wire is composed of an extrusion molding assembly, a magnetic powder pushing and feeding device, a glue injection assembly and a magnetic powder hopper; the extrusion molding assembly consists of a plastic screw extruder assembly and an extrusion molding mould, wherein the extrusion molding mould is connected with the plastic screw extruder assembly, and the plastic screw extruder assembly transfers plastic materials in a flowing state to the extrusion molding mould; the magnetic powder pushing and feeding device is tubular; the inner wall of the magnetic powder pushing and feeding device is provided with spiral pushing blades; the central axis of the magnetic powder pushing and feeding device is provided with holes through which the twisted core wires can pass; magnetic powder arranged inside the magnetic powder hopper can enter the magnetic powder pushing and feeding device through a discharging opening; glue is arranged inside the glue injection assembly and enters the magnetic powder under the driving of pressure. The magnetic powder is wrapped at the exterior of the core wires, and the soft magnetic properties of the magnetic powder can filter waves and decrease noise reduction.

Description

technical field [0001] The invention belongs to the technical field of equipment for transmitting high-frequency broadband digital signals, and in particular relates to an HDMI cable and a preparation device thereof. Background technique [0002] HDMI (High-Definition Multimedia Interface, high-definition multimedia digital signal transmission interface) is widely used in multimedia TV audio-visual equipment, which can transmit high-frequency broadband digital signals at the same time, including video signals, audio signals, and network signals. It has a compact structure and anti-interference , high-frequency broadband characteristics. With the accelerated popularization of digital multimedia television, HDMI cable devices are used more and more as a device for transmitting high-frequency broadband digital signals. In order to achieve the characteristics of electromagnetic compatibility, a magnetic ring is often placed at the interface of the HDMI cable, which is very unfa...
