Description
Technical field
The present invention relates to HDMI, particularly relate to a kind of HDMI for HDMI
Interface.
Background technology
HDMI(High Definition Multimedia Interface) it is meant that HDMI.
HDMI can provide the data transfer bandwidth of up to 5Gbps, can transmit the audio signal without compression
And high definition video signal.Simultaneously without transmitting advance row D/A or analog/digital conversion, Ke Yibao at signal
The video-audio signal transmission of card first water.HDMI is a kind of digitized video/COBBAIF technology, extensively should
For HD video/audio transmission.HDMI wire and HDMI connector collectively form HDMI.Therefore,
Say on conversational implication, it is only necessary to a HDMI wire, just can transmit video-audio signal simultaneously, and unlike now
A plurality of wire rod is needed to connect；Carry out D/A or analog/digital conversion simultaneously as wireless, can obtain higher
Voice & Video transmission quality.For consumer, HDMI technology can not only provide image quality clearly, and
And owing to audio/video uses same cable, enormously simplify the installation of household audio and video system.
Existing HDMI, including two parts, one is HDMI connector, and two is HDMI wire,
The structure of HDMI connector, the HDMI connector as described by patent application 201010251398.8, should
Connector, includes insulating body, first row terminal, second row terminal and shielding shell；This insulating body
Front end face extended anteriorly out a hyoplastron, be correspondingly arranged in the upper and lower surface of this hyoplastron upper end pilot trench,
Lower end pilot trench；This first row terminal is arranged on insulating body, and the Plug Division of first row terminal is embedded in lower terminal
In groove, the weld part of first row terminal is divided into two groups of left and right sides extending laterally insulating body respectively through bending
Outside face；This second row terminal is arranged on insulating body, and the Plug Division of second row terminal is embedded in the pilot trench of upper end,
The weld part of second row terminal stretches out the rear end face of insulating body backward；This shielding shell is coated on insulating body
Outside with hyoplastron.Thereby, it can be seen that existing HDMI connector be all double-row terminal structure arrange, with
Enable HDMI wire to arrange equably to weld.The most not only connector is more thick and heavy, and volume is relatively big,
And need two row Pin of upper and lower HDMI wire are filled tin creams, and heart yearn is divided into two rows welds
Connecing, there is uncontrollable factor, fraction defective is higher, the phenomenon such as missing solder, short circuit easily occurs, thus increases manufacture
Cost, affects production efficiency.
Existing HDMI wire structure, is all to be made up of multiply circle twisted wire, such as patent application
A kind of HDMI wire material described by 201020684119.2, this wire rod include at least heart yearn, at least one
The outer twisted component wires of root quilt outer with heart yearn, described heart yearn be internally provided with internal layer aluminium foil wheat draw, interior twisted component wires,
Internal cascading water ground wire and electromagnetism interference ground wire, outer wrap has outer foil wheat to draw, electromagnetism interference braiding
The outer quilt of layer heart yearn and heart yearn, interior twisted component wires, outer twisted component wires be round layer structure, including conductor layer and
Its outside insulating barrier arranged, the manufacture material of conductor layer be specification be the tinned wird of 36AWG, core
Line external diameter is 3.6 ± 0.15 millimeters.But this structure often brings a lot of difficulty to processing, be minimum
Processing multiple twisted wires in line footpath, well imagine it is highly difficult, processing cost is the highest simultaneously.And this
A little HDMI wire use twisted wire structure, add man-hour requirement and it is carried out sequence of operations, including de-outer quilt, de-
Aluminium foil, sleeve-penetrating, hot blast blowpipe, separated time, trimming core, it could be subjected to after depoling line,
Operation is a lot of, and separated time step needs two rows Pin is filled tin cream, and heart yearn is divided into upper and lower two
Discharging into row welding, manual identified pin position to be relied on defines, and carries out separated time for pin position twisted pair wire.This
Sample can bring the inconvenience in processing, adds operation and cost.
