Description
Technical field
The utility model relates to a kind of improved cable structure, relates in particular to a kind ofly can effectively dwindle the cable volume, reaches simple in structure and reduces the cable of manufacturing cost.
Background technology
" high frequency transmission yarn structure " that No. the 242835th, the structure of general cable such as TW patent, as shown in Figure 3, it includes: one or more transmission channel 60, each transmission channel 60 includes the lead 61 of two execution electrical equipment communication; One or more are coated on the interior body 62 in each transmission channel 60 outside respectively, and body 62 includes alignment layers 621, an insulating barrier 622 and a conductive layer 623 of a contained above-mentioned lead from inside to outside in this; The ground wire 63 that electrically connects with conductive layer around the body 62 at least more than one is disposed at; One is coated in the outer sleeve body 64 that outermost layer is used the protection cable.
Though the high frequency transmission yarn structure of above-mentioned traditional usefulness can reach the effect of transmission signal, but because its interior body 62 of this high frequency transmission yarn structure is made of alignment layers 621, insulating barrier 622 and conductive layer 623, and two sides of each transmission channel 60 are respectively arranged with a ground wire 63, therefore, need four ground wires 63 to constitute altogether, so cause this cable to have complex structure, be difficult for making, volume is more roomy and manufacturing cost is higher shortcoming.
In addition, United States Patent (USP) US 6,444,902B1 number " cable ", as shown in Figure 4, comprising a pair of Communication signal wire group 70, each Communication signal wire group 70 is provided with a pair of layer 71 Communication signal wire that is wrapped up 72 that are insulated respectively, and be wrapped in this to the metallic shield circle 73 outside the insulating barrier 71 of Communication signal wire 72, a first exposed earth lead 74 is folded in this inboard to Communication signal wire group 70, the a pair of second exposed earth lead 75 is arranged at this outside to Communication signal wire group 70, above-mentioned first, second earth lead 74,75 all electrically contact mutually with the outer surface of corresponding metal shielding ring 73.
Though " cable " of this United States Patent (USP) can improve the shortcoming of above-mentioned tradition " high frequency transmission yarn structure ", but first, second earth lead 74,75 is set respectively owing to reach a side between each Communication signal wire group 70 of this United States Patent (USP), therefore, only reduce by a ground wire under being somebody's turn to do " cable " structure and " high frequency transmission yarn structure " comparing, really do not reduce the integral width of " cable ", so, see it with this United States Patent (USP), its cable is limited with the effect that reduces manufacturing cost in reduction in bulk; Moreover because therefore the volume wider width of aforementioned two kinds of traditional wire rods, is easier to be subjected to the position of institute's desire setting and the restriction in space in practice, and can't be applied in a flexible way.
Summary of the invention
Therefore, main purpose of the present utility model is to provide a kind of improved cable structure, and this structure can effectively be dwindled the cable volume, reaches effect simple in structure and the reduction manufacturing cost.
In order to achieve the above object, a kind of improved cable structure of the utility model, it comprises first and second signal transmission unit with two conductors and insulating barrier, and this second signal transmission unit is located at a side of the first signal transmission unit; Coated the insulating barrier outside of first and second signal transmission unit respectively by shielding layer, a surface of this shielding layer is an insulating surfaces, and this insulating surfaces contacts with the insulating barrier of above-mentioned first and second signal transmission unit, and another surface of this shielding layer then is a conducting surface; Be located at the earth connection between first and second signal transmission unit, and two sides of this earth connection contact simultaneously with the conducting surface of this shielding layer; And first and second signal transmission unit and earth connection are coated by a coating layer.
By said structure, the improved cable structure of the utility model can effectively dwindle the cable volume, reaches effect simple in structure and the reduction manufacturing cost.

Embodiment
See also Figure 1 and Figure 2, three-dimensional appearance schematic diagram that is respectively and profile status schematic diagram of the present utility model.As shown in the figure: a kind of improved cable structure of the utility model, it is made of one first signal transmission unit 1, one second signal transmission unit 2, shielding layer 3, an earth connection 4 and a coating layer 5.
The above-mentioned first signal transmission unit of carrying 1 includes two conductors 11,12 and is coated on the insulating barrier 13,14 of conductor 11,12 outsides respectively.
This second signal transmission unit 2 is arranged at a side of the above-mentioned first signal transmission unit 1, and this second signal transmission unit 2 includes two conductors 21,22 and is coated on the insulating barrier 23,24 of conductor 21,22 outsides respectively.
Each shielding layer 3 is coated on insulating barrier 13,14,23,24 outsides of above-mentioned first and second signal transmission unit 1,2 respectively, and a surface of this shielding layer 3 is an insulating surfaces 31, this insulating surfaces 31 contacts with this insulating barrier 13,14,23,24, and another surface of shielding layer 3 then is a conducting surface 32.
