The cable provides an effective earthing function, reduces the whole volume, has lower manufacture cost, and can be widely suitable for the wiring requirement of a computer host in a narrower space.
Description
Technical field
The utility model relates to a kind of signal transmission cable, especially a kind of cable that is used for transmission current signal between the disc driver.
Background technology
Because the progress of electronic technology, small and exquisite consumption electronic products more and more receive consumer's concern.The cable that is used for transmission signals correspondingly requires its volume more and more littler as the annex of consumption electronic products.Along with development of computer, a kind of cable as the hard disk transmission signals arises at the historic moment, and it is commonly called the serial ATA connector.This serial ATA connector can make bandwidth or the data capacity between the disc driver increase doubly, and it transmits signal between disk by the single line cable usually.With reference to figure 1, the existing cable that is used for transmission current signal between disk, comprise a pair of signal conductor group, wherein, each lead group comprises a pair of signal conductor 31,32 that is insulated layer coating respectively and is located at this a pair of exposed earth lead 41,42 to signal conductor 31,32 outsides.And all signal conductors 31,32, earth lead 41,42 all are arranged side by side and its axis is in the same plane, make the flat that is shaped as of cable integral body.One metal screen layer 2 is coated on the signal conductor 31,32 of each lead group and the outer surface of earth lead 41,42, and this metal screen layer 2 electrically contacts with each earth lead 41,42.This metallic shield circle has shielded the electromagnetic interference between the adjacent signals lead group again when having stoped the outside launching electromagnetic wave of cable institute electric current transmitted signal.In addition, an insulating protective layer 1 is coated on the outer surface of above-mentioned metal screen layer 2.The planar structure of this cable has certain advantage on circuit laying and some other application-specific.Yet; also insert and put the part insulating protective layer between the above-mentioned signal conductor group; the number of earth lead is more simultaneously; thereby increased the integral width of this cable and made its manufacturing process complicated; and then cause production cost higher; and increase in the inner occupation space of main frame, can not satisfy the more and more demand of miniaturization development of hosting space.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of client cables that is used for transmission current signal between computer disk, this cable effective grounding function is provided and make the cable overall volume diminish with and manufacturing cost lower.
For solving the problems of the technologies described above; the utility model adopts following technical scheme: client cables; comprise exposed earth lead; at least one pair of signal conductor group and be coated on described earth lead and the insulating protective layer of signal conductor group periphery; described signal conductor group comprises the complex root holding wire; this every group of signal line group skin all is coated with metal screen layer; described signal conductor and earth lead all be provided with in mode side by side and their central axis in the same plane; described earth lead is one; place the outside of signal conductor group metal screen layer and electrically contact with its outer surface, and the every group of outer field metal screen layer outer surface of signal line group electrically contact mutually.
When described metal screen layer was tin copper composite bed, the effect of shielded signal was preferable.
The insulation protection laminar surface of described cable has scale marker.
The 50 centimetres of settings in the every interval of the scale marker of described cable insulating protective layer outer surface.
Described cable insulating protective layer is that high density polyethylene (HDPE) is made.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the beneficial effects of the utility model are: the utility model client cables only is provided with an exposed earth lead, and be placed on the outside of signal conductor group metal screen layer and electrically contact with the outer surface of screen, the every group of outer field metal screen layer outer surface of signal line group electrically contact mutually simultaneously, therefore the current signal that metal screen layer shielded can reach effective grounding function by this electrical connection, and significantly reduced the number of earth lead, thereby make this cable have relatively little integral width and lower manufacturing cost.
Description of drawings
Fig. 1 is the existing cable cross sectional representation that is used for transmission current signal between disc driver;
Fig. 2 is the cross sectional representation of the utility model client cables.
Embodiment
Further specify embodiment of the present utility model with reference to the accompanying drawings.
With reference to figure 2, the utility model client cables comprises an exposed earth lead 6 and at least one pair of signal conductor group; The periphery of earth lead 6 and signal conductor group is coated with insulating protective layer 5; This signal conductor group comprises the holding wire 7 more than two or two, and holding wire is made of metal-cored and its outer field insulated hull.In order to stop the outside launching electromagnetic wave of cable institute electric current transmitted signal, the electric current transmitted signal of cable own is not subjected to the electromagnetic interference between the adjacent signals lead group again simultaneously, skin every group of signal line group all is coated with metal screen layer 81,82, all signal conductors 7 and earth lead 6 all are provided with in mode side by side, and their central axis is in the same plane, and the integral body of cable is flat.Earth lead 6 places signal conductor group metal screen layer 81, perhaps place the outside of metal screen layer 82, exposed earth lead 6 is realized electrically contacting with the outer surface of screen 81, simultaneously, make every group of outer field metal screen layer 81 of signal line group, 82 outer surfaces are realized electrical contact mutually, therefore, metal screen layer 81,82 current signals that shielded can reach effective grounding function by this mutual electrical connection, reduce the number that has lacked earth lead 6 simultaneously, make the cable integral width less, reduce the manufacturing cost of cable, realized comparatively considerable economic.
When described metal screen layer 81,82 was tin copper composite bed, the effect of shielded signal was preferable.For convenient in use as required length carry out cutting and budget is reasonably connected up, be provided with scale marker at the outer surface of cable insulating protective layer 5; This scale marker the best is the 50 centimetres of settings in every interval.
In order to make cable have stronger pliability and higher mechanical strength, this cable insulating protective layer 5 is made for high density polyethylene (HDPE).
Above-mentioned only is embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
