Description
Technical field
The invention belongs to the equipment technical field of transmission high-frequency wideband digital signal, be specifically related to a kind of HDMI electric wire and preparation facilities thereof.
Background technology
HDMI (High-DefinitionMultimediaInterface, high-definition multimedia digital data transmission interface) it is widely used in multimedia television audio-visual devices, high-frequency wideband digital signal can be transmitted simultaneously, including signal of video signal, acoustical signal, network signal, just there is compact conformation, anti-interference, the feature of high-frequency wideband. Along with the acceleration of digital multimedia TV is popularized, HDMI cable device, as a kind of equipment transmitting high-frequency wideband digital signal, is more and more used. In order to reach the characteristic of electromagnetic compatibility, often placing magnet ring at the interface position of HDMI cable, this is highly detrimental to HDMI cable through narrow and small space, affects the use of user.
As can be seen here, above-mentioned existing HDMI cable device still suffers from defect, and is urgently improved.
Because the defect that above-mentioned existing HDMI cable device exists, the design people is based on being engaged in this type of product design manufacture for many years, long-pending have abundant practical experience and Professional knowledge, actively in addition research and innovation, to founding a kind of HDMI electric wire, the molding structure of general existing HDMI electric wire on the market can be improved so that it is have more competitiveness. Through constantly research, design, and after repeatedly studying sample and improving, finally create the present invention having practical value.
Summary of the invention
The shortcoming existed in using for existing HDMI cable, the present invention provides a kind of HDMI electric wire, is applied to high-definition multimedia digital data transmission, solves the problem needing additional magnet ring.
The present invention is realized in, a kind of HDMI electric wire, HDMI electric wire is made up of twisted component wires, magnetic blow out coating and plastic layer, from cross section, magnetic blow out coating parcel twisted component wires, plastic layer parcel magnetic blow out coating, twisted component wires is formed by two wire pair twists, the material of magnetic blow out coating is iron powder or the powder of other paramagnetic material, and the material of plastic layer is the one in PVC, crosslinked polyethylene and PE.
A kind of device preparing above-mentioned HDMI electric wire, this device is by extrusion molding assembly, magnetic powder pusher, glue injecting assembly and magnetic powder hopper composition, extrusion molding assembly is made up of plastic cement Screw Extrusion thermomechanical components and extruded mould, extruded mould connects plastic cement Screw Extrusion thermomechanical components, plastic cement Screw Extrusion thermomechanical components is in the plastic material of flow regime to extruded mould conveying, magnetic powder pusher is in a tubular form, the inwall of magnetic powder pusher has helical form to advance blade, the axis of magnetic powder pusher has can by the hole of twisted component wires, the magnetic powder placed in magnetic powder hopper can pass through lower drain port and enter magnetic powder pusher, glue is had inside glue injecting assembly, glue enters magnetic powder under the promotion of pressure.
Present invention have an advantage that parcel magnetic powder outside heart yearn, the soft magnet performance of magnetic powder can play the effect of filtering, noise reduction, for magnetic powder for iron powder, and iron powder under pressure mutually against, there is certain electric conductivity, therefore can playing the effect of electric shield, the reasonable soft magnet performance of iron powder can also play the effect of filtering, noise reduction simultaneously; This preparation facilities is little for the change of traditional extrusion apparatus, there is good application foundation, magnetic powder is close to heart yearn under the extruding and conveying of magnetic powder pusher, the plastic layer flowed in extruded mould position wraps up, magnetic powder forms stable magnetic blow out coating under the adhesive effect of glue, and this magnetic blow out coating twists at follow-up HDMI electric wire and keeps sizing in process processed.
