Abstract
The utility model relates to a cable comprising first conductors and second conductors which are arranged adjacently but not mutually twined. The first conductors and the second conductors are arranged in one row in order to substantially improve high-frequency performance of the signal transmission. In the meantime, anti-EMI materials such as conductive cloth are prevented and cost is further reduced while dependency to human is reduced. The product has wide application scope.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of LVDS or coaxial cable.
Background technology
Generally include in each single coaxial cable: (1) is by the number of metal material, like the central core of copper alloy conductor composition; (2) be coated on insulated hull in the peripheral one deck of heart yearn, generally process by teflon (polytetrafluoroethylene) material; (3) be coated on the peripheral layer of metal braid of interior insulated hull; (4) be arranged on the outer quilt of outermost insulation, said insulation is outer is normally adopted plastic cement material, for example PVC.
Along with the quickening of the signaling rate on the electronic equipment, the shielding of electromagnetic interference has also been proposed increasingly high requirement, in order to reduce the electromagnetic interference between the adjacent signals line, can in per two adjacent circular holding wires, a circular earth lead be set usually.Yet the cable of this spline structure still can't reach desirable high frequency performance, influences the quality of signal transmission; And very consuming time when carrying out weld job with corresponding conducting terminal, the lost labor is unfavorable for volume production.
Therefore, very be necessary to design a kind of novel cable, to solve the problems of the technologies described above.
The utility model content
The purpose of the utility model provides a kind of cable that improves anti-electromagnetic interference (EMI).
For reaching aforementioned purpose, the utility model adopts following technical scheme: a kind of cable, comprise the mutual of adjacent setting less than first conductor and second conductor that twine, and said first conductor becomes a row with second conductor arrangement.
As the further improvement of the utility model, said first conductor transmits differential signal, and second conductor transmits ground signalling.
As the further improvement of the utility model, at least one second conductor of the left and right sides of adjacent two aforementioned first conductors collocation.
As the further improvement of the utility model, said first conductor is a flat.
As the further improvement of the utility model, said second conductor is the circle shape.
As the further improvement of the utility model, said second conductor is non-round shape.
As the further improvement of the utility model, said first conductor is non-round shape.
As the further improvement of the utility model, said cable is coaxial cable or LVDS cable.
Compared to prior art, first conductor and second conductor that do not twine each other of adjacent setting on the cable in the utility model, said first conductor becomes a row with second conductor arrangement; Conductor shape is carried out the differentiation setting; The screen that at least one side shielding of conductor has special material to process plays control group, improves the high frequency performance of signal transmission; Can save simultaneously EMI suppression materials such as conductive fabric, further reduce cost.Cable in the utility model reduces according to patience manual work, and the scope of application of product is wider.
Description of drawings
Fig. 1 is the solid combination sketch map of the utility model cable.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, the utility model is described in detail below in conjunction with accompanying drawing and specific embodiment.
See also shown in Figure 1ly, the cable 100 in the present embodiment can be LVDS cable or coaxial cable, and said cable 100 comprises first conductor 1 and second conductor 2 that do not twine each other of adjacent setting, and said first conductor 1 is non-round shape, for example flat; Said second conductor 2 is circle shape or non-round shape.Said cable 100 has structure example such as interior insulated hull, the outer quilt of insulation in the existing cable equally.
Said first conductor 1 transmits differential signal, and circle shape second conductor 2 transmits ground signalling.At least one second conductor 2 of left and right sides collocation of adjacent two aforementioned first conductors 1.
Said first conductor, 1 one sides or bilateral have shielded special material through certain pressing mode.Said second conductor, 2 one sides or bilateral have special material through certain pressing mode one side shielding.
Said first conductor 1 and second conductor 2 are arranged in a row.
Cable in the utility model is through carrying out the differentiation setting to conductor shape; The screen that at least one side shielding of conductor has special material to process plays control group, improves the high frequency performance of signal transmission; Can save simultaneously EMI suppression materials such as conductive fabric, further reduce cost.Cable in the utility model reduces according to patience manual work, and the scope of application of product is wider.
In sum; More than be merely the preferred embodiment of the utility model; Should not limit the scope of the utility model with this; Be that every simple equivalent of being done according to the utility model claims and utility model description changes and modifies, all should still belong in the scope that the utility model patent contains.
