Abstract

The utility model discloses a data transmission line structure, which comprises a sheath, a shielding layer, a signal wire and a power wire, wherein the shielding layer is clung to the inner surface of the sheath; the signal wire is the insulated core wire covered in the sheath; the power wire is divided into two parts, one part of the power wire is covered in the sheath, and the other part of the power wire is the enamelled copper wire arranged in the shielding layer; according to the actual requirement, the power wire covered in the sheath can be the insulated core wire or the enamelled copper wire; and a metal composite membrane layer is arranged between the shielding layer and the signal wire inside the shielding layer and between the shielding layer and the power wire. Therefore, the wire material or position can be changed to reduce the external diameter of a data transmission line, the external diameter of the data transmission line is not difficult to reduce any more when the voltage drop requirements on the data transmission line are met, the design and manufacturing difficulties of the manufacturers are reduced, and the data transmission line structure is more adapted to the industry specifications.

Description

The transfer of data line structure

Technical field

The utility model relates to the data line art, especially a kind of transfer of data line structure that adopts enamel covered wire as power line.

Background technology

At present, along with the competition of household electrical appliances market is growing more intense, the various countries dealer has released mini electrical home appliances one after another, to cause numerous consumers, for example mini television set, mini computer, mini display, mini PC and multiple portable mini electronic equipment, these electronic products are subjected to youthfully at present to like that the huge market is arranged very much.

These electronic products generally need carry out transfer of data with data line, this class data line is as shown in Figure 1: generally by two holding wires, two power lines and parcel holding wire, the screen of power line and sheath are formed, its weak point is: as reducing the data line external diameter, must reduce its internal power cord and holding wire diameter, yet, power line and holding wire material are the insulation heart yearn in this type of data line, this type of insulation heart yearn comprises insulated hull and plain conductor, reducing the insulating core linear diameter need reduce plain conductor diameter and insulated hull thickness or reduce one of them, but, this method that reduces the data line external diameter is difficult in to satisfy under the prerequisite that pressure drop requires and realizes, therefore, reduce the data wire external diameter and become the right problem of manufacturer's demand side, the difficulty of having brought design and having produced to manufacturer, therefore, should improve.

The utility model content

In view of this, the utility model is at the disappearance of prior art existence, and its main purpose provides a kind of transfer of data line structure, and it can effectively solve the available data transmission line and reduce the relatively problem of difficulty of its external diameter when satisfying the pressure drop requirement.

For achieving the above object, the utility model adopts following technical scheme:

A kind of transfer of data line structure, include sheath, screen, holding wire and power line, screen is close to the inner surface of sheath, this holding wire is the insulation heart yearn that is coated in the sheath, this sub power source line is two parts, a part is coated in the sheath, and another part is the enamel covered wire that is arranged in the screen.

As a kind of preferred version: this power line that is coated in the sheath is the insulation heart yearn.

As a kind of preferred version: this power line that is coated in the sheath is an enamel covered wire.

As a kind of preferred version: be provided with layer of metal THIN COMPOSITE rete between this screen and its inner holding wire and the power line.

The notebook data transmission line structure compared with prior art has tangible advantage and beneficial effect, particularly, as shown from the above technical solution, by enamel covered wire being arranged in the screen as one of power line, another power line is enamel covered wire or insulation heart yearn, thereby, reduce the data line external diameter, this structure has replaced the structure that power line in the available data transmission line all is the insulation heart yearn, and by contrast, this structure is when satisfying data line pressure drop requirement, it is fairly simple to reduce its external diameter, by this, the difficulty on this transfer of data line structure can design and make to manufacturer's minimizing, thus adapt to the industry specification requirement more.

Be architectural feature and the effect of more clearly setting forth the notebook data transmission line structure, come it is elaborated below in conjunction with accompanying drawing and specific embodiment.

Fig. 1 is the available data transmission line structure schematic diagram of the utility model preferred embodiment;

Fig. 2 is first kind of embodiment schematic diagram of the utility model preferred embodiment;

Fig. 3 is second kind of embodiment schematic diagram of the utility model preferred embodiment.

The accompanying drawing identifier declaration:

10, holding wire 20, power line

30, metal composite thin film layer 40, screen

50, sheath.

Embodiment

The utility model includes holding wire 10, power line 20, metal composite thin film layer 30, screen 40 and sheath 50 as shown in Figure 2 to Figure 3.

This sheath 50 is made by insulating material, and it mainly acts on is that data line and external environment condition are isolated, and the protected data transmission line is avoided the influence of external environment condition.It places the outermost layer of data line, and is provided with screen 40 in sheath 50, is provided with metal composite thin film layer 30 in the screen 40, and metal composite thin film layer 30 is coated on holding wire 10 and power line 20 outsides.

These holding wire 10 materials are the insulation heart yearn, and it includes insulating barrier and plain conductor, and insulating barrier is coated on the plain conductor, with isolating metal lead and other line.

This power line 20 is divided into two parts, a part is an enamel covered wire, and this enamel covered wire is the copper cash that a kind of top layer is coated with insulating varnish, and is arranged in the screen 40, to reduce the external diameter of data line, another part is the insulation heart yearn that is coated in the metal composite thin film layer 30.

This metal composite thin film layer 30 adopts aluminum plastic composite belt longitudinal bag overlap joint, forms the double layer screen mode with screen 40, and the opposing electromagnetic interference guarantees stable signal transmission.

This screen 40 is the tin-coated copper mesh grid, and coverage rate reaches more than 90%, with big limit opposing electromagnetic interference.

As second kind of embodiment, when in screen 40 enamel covered wire being set, another power line 20 also can be selected enamel covered wire for use in this data line, thereby, can make data line external diameter excursion bigger, to satisfy the different size requirement of data line.

Design focal point of the present utility model is, place screen 40 by two one of thoroughly doing away with in the edge heart yearn that power line 20 will be served as in the data line, and the heart yearn that should insulate is changed to enamel covered wire, another thoroughly does away with edge heart yearn and also can change or keep original material according to the specification needs, this structure has replaced the interior power line 20 full structures for the insulation heart yearn of data line in the prior art, by contrast, this structure reduces the data line external diameter under the situation that satisfies the pressure drop requirement method is simple, operability is stronger, can adapt to the different requirements of data line external diameter, reduce the difficulty of manufacturer when design creation data transmission line.

The above, it only is preferred embodiment of the present utility model, 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 made.
