Abstract
The utility model relates to a twin-core flat mini transmission line which comprises two core wires in parallel arrangement, a woven layer, a copper foil tape and an insulating coating, wherein the two core wires are wrapped by the woven layer, the woven layer is wrapped by the copper foil tape, the copper foil tape is wrapped by the insulating coating, and each core wire consists of a plurality of conductors stranded together and an insulating coating. The design that the two core wires are in parallel arrangement and wrapped by the woven layer achieves the effects of excellent shield effect, good surge impedance and stable signal performance. The twin-core flat mini transmission line has the advantages of simple structure and high practicability.
Description
Technical field
The utility model relates to the electric wire field, refers in particular to a kind of twin-core and weaves miniature transmission line.
Background technology
Twin-core transmission line kind is more at present, and it is particularly crucial how to design shielding construction, and it directly can have influence on the stability of signal transmission; At present, still there are defectives such as characteristic impedance is poor, signal transmission instability in known twin-core transmission line.
The utility model content
The utility model is at the existing disappearance of above-mentioned prior art, and main purpose is to provide the twin-core that a kind of characteristic impedance is good, signal performance is stable flat miniature transmission line.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
The flat miniature transmission line of a kind of twin-core comprises two heart yearns of arranging side by side, a braid, a Copper Foil band and the outer quilt of an insulation, and these two heart yearns are wrapped up by this braid, and this braid is wrapped up by the Copper Foil band, and this Copper Foil band is insulated outer being wrapped; The conductor that described each heart yearn twists together by complex root and the insulating barrier of outer wrapping constitute.
The utility model advantage is to be provided with and by the design of braid parcel, can to make shield effectiveness good by two heart yearns are parallel, and it is good to reach characteristic impedance, the effect that signal performance is stablized.The utility model is simple in structure, practical.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model transmission line.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the flat miniature transmission line of a kind of twin-core comprises that two heart yearns of arranging side by side 1, a braid 2, a Copper Foil band 3 and an insulation are outer by 4, wherein:
These two heart yearns 1 are by these braid 2 parcels, and this braid 2 is by Copper Foil band 3 parcels, and this Copper Foil band 3 is wrapped up by 4 outside being insulated.
So the utility model design focal point is to be provided with and by the design of braid 2 parcels, it is good to reach characteristic impedance, the effect that signal performance is stablized by two heart yearns 1 are parallel.Through through facts have proved, the characteristic impedance of this kind transmission line (Differential Impedance) is 50 ± 2 Ω, and signal transmission performance is stable under the frequency of 18G.
The above, it only is the preferred embodiment of the utility model structure, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
