Description
Technical field
The present invention relates to electric wire, relate in particular to a kind of electric wire for HDMI (High Definition Multimedia Interface).
Background technology
HDMI(High Definition Multimedia Interface) implication is HDMI (High Definition Multimedia Interface).The HDMI interface can provide the data transfer bandwidth up to 5Gbps, can transmit audio signal and high definition video signal without compression.Need not simultaneously to transmit at signal advance capable D/A or mould/number conversion, can guarantee that the video-audio signal of first water transmits.HDMI is a kind of digitized video/audio interface technology, is widely used in HD video/audio transmission.HDMI line and HDMI connector form the HDMI interface jointly.Therefore, say on conversational implication, only need a HDMI line, just can transmit simultaneously video-audio signal, and unlike needing now many wire rods to connect; Simultaneously, due to wireless, carry out D/A or mould/number conversion, can obtain higher Voice ﹠ Video transmission quality.For the consumer, the HDMI technology can not only provide image quality clearly, and, because audio/video adopts same cable, has greatly simplified the installation of household audio and video system.At present, HDMI mainly contains the HDMI line of 4 kinds of forms, is respectively A Type, B Type, and C Type and D Type, wherein B Type is 29pin, and A, C, D are 19pin, and A Type is the HDMI line of standard; Type B interface size is slightly large, but 29 pins are arranged, and double T MDS transmission channel can be provided, and supports that therefore higher data transmission rate is connected with Dual-Link DVI; And C Type is mainly used in mancarried device, such as: DV, digital camera etc.; D Type belongs to mini-port, is mainly used in mobile phone, MP4, MP5 etc.
existing HDMI line structure, all to be formed by multiply sugarcane shape twisted wire, the described a kind of HDMI wire rod of patent application 201020684119.2 for example, this wire rod comprises at least one heart yearn, the outer quilt of at least one outer twisted component wires and heart yearn, the inside of described heart yearn is provided with internal layer aluminium foil wheat and draws, interior twisted component wires, inner cascading water ground wire and anti-electromagnetic interference ground wire, outer wrap has the outer foil wheat to draw, the outer quilt of anti-electromagnetic interference braid heart yearn and heart yearn, interior twisted component wires, outer twisted component wires is the Ru layer structure, the insulating barrier that comprises conductor layer and outer setting thereof, the manufactured materials of conductor layer is that specification is the tinned wird of 36AWG, the heart yearn external diameter is 3.6 ± 0.15 millimeters.But this structure tends to bring a lot of difficulties to processing, process a plurality of twisted wires in minimum wire diameter, well imagines it is very difficult, and processing cost is also higher simultaneously.
And these HDMI lines use twisted wire structures, add and need to carry out sequence of operations to it man-hour, comprise and take off outer quilt, the dealuminzation paper tinsel, sleeve-penetrating, hot blast blowpipe, separated time, could carry out welding operation to it after trimming core, depoling line, operation is a lot of, and the separated time step need to be filled tin cream with two rows Pin, and heart yearn is divided into two rows welds, rely on the definition of manual identified pin position, and for pin position twisted pair wire, carry out separated time.The inconvenience in processing be can bring like this, operation and cost increased.
Summary of the invention
Based on this, primary and foremost purpose of the present invention is to provide a kind of line of HDMI for HD video/audio-frequence player device, this HDMI line adopts the parallel placement of multiply metallic cable and the parallel construction of the insulation unit of fitting up and down, do not need the definition of manual identified pin position, the maximization simplification technological process, reduce manual work, significantly improved production efficiency.
A further object of the present invention is to provide a kind of line of HDMI for HD video/audio-frequence player device, this HDMI line has the structure of flat wire, takes up room little, makes HDMI line of the present invention more frivolous, greatly reduce the weight of HDMI line, reduce cost of manufacture.
Be to provide a kind of line of HDMI for HD video/audio-frequence player device, this HDMI line can have good shield effectiveness another order of the present invention, and the characteristic impedance control range is accurate, stable, guarantees the stability of signal transmission.
, for achieving the above object, the objective of the invention is to be achieved through the following technical solutions.
