The shadow data soft arranging wire
Technical field
The utility model relates to a kind of improvement of flat data soft rowed line structure.
Background technology
Flat data soft arranging wire is a kind of connection cable that is widely used in signal transmission in the electronic circuit: in the various electronics such as computer, TV, photocopier, printer, household electrical appliance and instrument and meter, it has, and volume is small and exquisite, line is efficient and convenient, the many advantages that the transmission information amount is large.
Develop rapidly along with the IT industry, the speed of data is more and more faster, capacity is increasing, frequency is more and more higher, therefore also more and more harsher to the requirement of transport vehicle, the data soft arranging wire should satisfy the large capacity of data as the transport vehicle of transmission multi-group data, the transmission requirement of two-forty also should have anti-cross-talk, jamproof characteristics.But present soft arranging wire mainly comprises insulating barrier and is coated on metal data heart yearn in the insulating barrier, and metal data heart yearn comprises some wide, uniform thickness and the metallic conductor that is arranged in parallel.The external disturbance problem appears in this soft arranging wire inevitably in transmitting high-frequency signal, the shield effectiveness of its transfer of data is relatively poor.
The utility model content
For the existing above-mentioned deficiency of prior art, technical problem to be solved in the utility model provides the shadow data soft arranging wire that a kind of shield effectiveness is remarkable, antijamming capability is strong.
In order to solve the problems of the technologies described above, shadow data soft arranging wire of the present utility model, it comprises some data heart yearns and insulating barrier, this data heart yearn adjacent spaces is coated on described insulating barrier inside with arranging, is coated with screen at the lateral surface of described insulating barrier.
After adopting said structure, owing to being coated with screen at the lateral surface of data soft arranging wire insulating barrier, various interference electromagnetic waves have strengthened the whole antijamming capability of data to the interference of data soft arranging wire in the electronic equipment thereby effectively blocked.When the signal transmission was arranged, the high-frequency signal electromagnetic field of transmission was limited between signal transmission body and the screen, and its decay diminishes, and the cross-talk between the signal transmission heart yearn of signal transmission body and vicinity is also little, is conducive to the transmission of high-frequency data signal.Adopt simultaneously shielding layer structure also to strengthen the structural stability of data heart yearn in the insulating barrier, improved the performance such as tension, shock resistance of soft arranging wire, not only have good electric property, and have preferably physical property.
A kind of preferred implementation of the present utility model, screen are metal copper wire woven shield.Screen adopts metal copper wire braiding structure to have preferably integrally bending performance, has both had shield effectiveness, does not affect again the flexibility of winding displacement.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model shadow data soft arranging wire is described in further detail.
Fig. 1 is the main TV structure schematic diagram of a kind of embodiment of the utility model shadow data soft arranging wire;
Fig. 2 is the left view of structure shown in Figure 1;
Among the figure, 1-screen, 2-insulating barrier, 3-data heart yearn, 4-stiffener.
Embodiment
In Fig. 1, shadow data soft arranging wire shown in Figure 2, six roots of sensation data heart yearn 3, the adjacent rods arranged in horizontal line that is with interval, and each data heart yearn 3 is parallel to each other, and each data heart yearn 3 is the copper lines that the cross section is flattened rectangular.There is insulating barrier 1 both sides at data heart yearn 3 by the PUR pressing, and this insulating barrier 1 is made by the flame retardance poly ester material, have preferably intensity and pliability, and it is carrier and the insulation retaining layer of data heart yearn metallic conductor.In two sides of insulating barrier 2 all by the bonding screen 1 that is coated with of PUR, the metallic shield woven mesh belt that screen 1 is woven into for the metal copper wire.Homonymy at the data wire two ends posts stiffener 4 by melt viscosity, and this stiffener 4 is made by the flame retardance poly ester material, to increase the intensity of data wire, makes it to be easy to insert in the plug connector.
Above-mentionedly enumerated a kind of preferred implementation of the present utility model, but the utility model can also be made some improvement and conversion, can also be to make with aluminium foil or Copper Foil such as screen, or adopt aluminium-plastic tape etc.These conversion all fall in the hold in range of the present utility model.
