Abstract

The utility model discloses an improved data transmission wire structure which comprises a sheath, a shielding layer, signal wires and power cords, wherein the shielding layer, as well as the signal wires and the power cords in the shielding layer, are wrapped in the sheath, the power cords are enameled copper wires, the signal wires are insulated core wires, the two power cords and the two signal wires are arranged in the data wire, and a metal compound thin film layer is arranged between the shielding layer and the signal wires and the power cords contained in the shielding layer. Accordingly, by using the data transmission wire structure, the reduction of the outer diameter of the data transmission is not difficult any more under the situation of meeting the requirements of pressure drop by changing the material or the position of the wire so as to reduce the outer diameter of the data transmission wire, thereby reducing the difficulty in design and manufacturing of a manufacturer and being more suitable for the specification requirements of the industry.

Description

The transfer of data line structure of improvement

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 wire, prior art 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, power line and holding wire are the insulation heart yearn, 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 kind 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, therefore difficulty to manufacturer has brought design and produced, 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 of improvement, 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 of improvement includes sheath, screen, holding wire and power line, comprises the holding wire and the power line of screen and screen inside in this sheath; This power line is an enamel covered wire; This holding wire is the insulation heart yearn.

As a kind of preferred version: two power lines and two holding wires are arranged in the described data wire.

As a kind of preferred version: be provided with layer of metal THIN COMPOSITE rete between holding wire that described screen and its inside are comprised 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, change power line material in the data wire into enamel covered wire by the insulation heart yearn, this structure can be when satisfying data wire pressure drop requirement, it is fairly simple to reduce its external diameter, 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.

Description of drawings

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

Fig. 2 is the 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 such as Fig. 1 include holding wire 10, power line 20, metal composite thin film layer 30, screen 40 and sheath 50 to shown in Figure 2.

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.

These power line 20 materials are enamel covered wire, and this enamel covered wire is the copper cash that a kind of top layer is coated with insulating varnish, and it can reduce the data wire external diameter as power line when satisfying data wire pressure drop requirement.

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.

Design focal point of the present utility model is, be changed to enamel covered wire by the two eradication edge heart yearns that power line 20 will be served as in the data line, thereby reduce the data line external diameter, by this, this structure is when satisfying data line pressure drop requirement, it is fairly simple to reduce its external diameter, the difficulty that has reduced design and made to manufacturer, thus adapt to the industry specification requirement more.

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.
