Description
Technical field
The present invention relates to holding wire technical field, particularly relate to a kind of Mini-LVDS (miniature low voltage difference
Signal) connecting line and preparation method thereof.
Background technology
LVDS (Low Voltage Differential Signaling) is a kind of little amplitude difference signal technique, makes
With low-down range signal (about 350mV) by a pair difference PCB trace or balanced cable transmission number
According to.It is less that Mini-LVDS is that one takes up room, and has a kind of interfacing of LVDS function,
Notebook computer plays an important role in high-resolution advances with liquid crystal display.The application of Mini-LVDS can
So that the line number signal in liquid crystal display control module to reduce sixty percent, then manufacturer shows at development whole plane
The when of showing device, the layout of circuit board not only can be allowed simpler, also can increase product task performance,
The cost of minimizing system, reduce the intensity of electromagnetic interference and save more electric power.
Being promoted by the ever-increasing resolution requirements of electronic equipment for consumption, the amount of data transmission is constantly
Increasing, electronic equipment for consumption is to lightening development simultaneously, less to internals corresponding requirements, thinner,
But transmission speed requires faster.Mini-LVDS is as the letter of the electronic equipment such as notebook computer, panel computer
Number transmission standard interface, data transmission capabilities must constantly promote, to meet above demand.
The heart yearn of traditional Mini-LVDS connecting line uses Teflon line, and the two ends of Teflon line are respectively welded
One divided connector；Divided connector by tens of metal terminals, an insulating body, one fix iron-clad
And shielding upper iron shell forms.The manufacturing process of this traditional Mini-LVDS connecting line is: cut out the de-outer quilt of line
→ Teflon line rubberizing location → stannum → welding → solder joint checks → UV glue → drying → adapter upper iron shell patch
Iron-clad → bag acetic acid cloth → electrical measurement → entirely examine is drawn → covered to wheat.
Above-mentioned traditional Mini-LVDS connecting line has the disadvantage that whole heart yearn all uses Teflon line, because of it
The advantages such as excellent thermally-stabilised and the wear-resisting electrical insulation capability of machinery are had, so having higher than other higher temperature lines
The market price so that the production cost of connecting line is higher.
Summary of the invention
It is an object of the invention to provide a kind of Mini-LVDS connecting line and preparation method thereof, reduce Teflon
The consuming of line, reduces production cost on the premise of ensureing stable electrical property.
It is an object of the invention to be achieved through the following technical solutions:
The present invention proposes a kind of Mini-LVDS connecting line, including: a LVDS adapter, first flat
Flat FFC, Teflon line, the second flat FFC, the 2nd LVDS adapter；
Described first flat FFC and the second flat FFC all includes the upper strata insulating coating fitted, arranges side by side
The multiply flat copper wire put, lower floor's insulating coating, outside the two ends of described multiply flat copper wire are exposed to, wherein
An exposed end and Teflon wire bonding, another exposed end assembles with first/second LVDS adapter；
The mid portion of the heart yearn of described Teflon line is rolled into cylindrical shape, and outside two ends are exposed to, wherein one is naked
The welding of multiply flat copper wire, another exposed end and the multiply of the second flat FFC of dew end and the first flat FFC
Flat copper wire is welded；
A described LVDS adapter is assembled in one end of the first flat FFC, the 2nd LVDS adapter group
It is loaded on one end of the second flat FFC.
Preferably, a described LVDS adapter/the 2nd LVDS adapter includes by a foil punching
The space that the confession flat copper wire formed is passed through, and the metal being bent to form in through hole by described foil
Upper casing and metal lower shell；The free end of described metal upper shell and metal lower shell be respectively equipped with suitable window and
Hanging platform；
When being assembled in one end of the first flat flat FFC of FFC/ second, this first flat FFC/ second is flat
After the multiply flat copper wire of flat FFC is passed through described space and stretched out, metal upper shell and metal lower shell pass through window
It is interlocked with hanging platform.
Preferably, described Teflon line is full-length, is specially the spindle portion of its computer passed
Length.
Preferably, one end of the first flat FFC and the second flat FFC is also fitted with stiffening plate.
Preferably, described first flat FFC and the upper strata insulating coating of the second flat FFC and/or lower floor are exhausted
Also post characteristic impedance outside edge epithelium and control material.
Preferably, a described LVDS adapter, the first flat FFC, Teflon line, the second flat FFC
And the connecting portion that the 2nd between LVDS adapter is enclosed with acetic acid cloth.
Compared with prior art, the embodiment of the present invention has the advantages that
1, lower than Teflon line due to the flat FFC line cost of equal length, and Teflon line is the longest
Quality is the most unstable, fraction defective is high, so present invention employs flat FFC welding standard length Teflon line
The structure of soldering flat FFC, Teflon line have employed shortest length, can standardized production, the most significantly drop
Low production cost, and stay in grade；
2, the divided connector complex manufacturing technology used in prior art, needs multiple stage high-precision equipment same
Shi Jiagong, manufacturing cost is high, and quality yield is low；And, divided connector is at the two ends with Teflon line
During welding, terminal can be made little with iron-clad spacing because volume is little, ultimately result in cost of labor height, welding not
Yield is high.And invent the LVDS adapter using integral type, with traditional split type LVDS adapter phase
Ratio, decrease material uses and assembles man-hour, improve product quality yield.
3, monolayer or double-layer characteristics impedance control material are posted in flat FFC surface, are effectively reduced signal
Interfering in transmission, it is ensured that the stability of signal transmission.
4, traditional structure Mini-LVDS connecting line is when assembling divided connector, need " some UV glue →
Drying → adapter upper iron shell Mylar attaching → cover iron-clad " technique, and the present invention uses integral connectors,
Have only to during assembling fasten integral connectors with flat FFC, enormously simplify whole connecting line
Fabrication processing, decreases manual work, and production efficiency is greatly improved.
