The invention has for its object to provide a twisted pair cable and a method for their preparation, wherein the twisted pair cable should be simple and inexpensive to produce. The invention is based on a twisted pair cable comprising a first conductor and a second conductor. The first conductor and the second conductor are electrically isolated from each other. The first conductor and the second conductor are twisted with respect to each other. The twisted-pair line extends in an extension direction, in particular along an extension line, which may be a straight line or curve and around which the first conductor and the second conductor are arranged twisted. The twisted-pair cable is flexible, ie mechanically flexible. It can be elastically or / and plastically destructively deformable.

In other words, a first line section is arranged substantially between two second line sections and / or a second line section is arranged between two first line sections. The first and second line sections can in particular be arranged completely in a common plane. The first and / or second line sections may in particular be elongated, such. B. strip-shaped, be configured and extend transversely or obliquely to the extension line of the twisted pair line, in particular with a first angle of inclination. The first inclination angle is the angle between the longitudinal axis of the conduit section and the extension line. The first line sections may be arranged parallel to one another. The second line sections may be arranged parallel to each other. Preferably, the first and second line sections are arranged parallel to each other. Between the first line sections and the second line sections is a separation, such. As a separation gap or printed on the substrate electrically non-conductive material. This additional material may, for. B. during printing of the first and second line sections are printed with. In general terms, before, after or during the printing of the plurality of line sections an electrically non-conductive layer, in particular (first) separation layer, for example on the substrate and / or preferably between the first and second line sections, in particular with the same layer thickness as the first and second line sections and / or in the same level as the line sections are printed, wherein on this layer, for example, the first non-conductive layer described below can be applied.

The first and second line sections, and preferably also the connection sections described below, are particularly flat, i. they have a small thickness compared to their length and width.

The printing of the first and second line sections by means of a printing process, such. B. by gravure, offset or flexographic printing. Also conceivable is a screen printing process. Particularly preferred for the present invention is an inkjet printing process, which may also be referred to as inkjet printing process. In the inkjet printing process, a liquid medium, such as a color, which may also be referred to as ink, applied to the substrate in particular dropwise, such as. B. with a plurality of nozzles, which are preferably used simultaneously. The liquid color may be in the form of a solution, dispersion or suspension. The color is electrically conductive. Possible colors include, inter alia, colloidal metal solutions, in particular silver ink, or nano-ink, which is used as an electrically conductive agent z. As carbon nanotubes, into consideration. The color can after printing on the substrate z. B. are cured by means of heat and / or UV radiation, such as. B. before the application of another layer. The application of non-conductive material, in particular the non-conductive layer or layers described herein, can also be effected by means of this printing process, in particular inkjet printing, wherein the ink is electrically non-conductive, at least when cured or dried. The thickness of the applied conductor sections may, for. B. by printing a thick layer of paint or multiple application of thin layers of paint can be varied in a simple manner, so that the cross-sectional thicknesses of the first and second line sections can be easily produced in any way. Thus, thick conductor cross sections can be produced printed.

The electrically non-conductive substrate comprises or is preferably a flexible film, in particular made of plastic, such as. As polyester or polyimide. A z. B. Thermoplastic plastic film may be present in particular with a layer thickness of 0.2 to 0.6 mm. Instead of a foil and profiled plastic strands are conceivable.

The substrate may be provided in the printing process arcuate or in the form of endless goods, which is wound on a roll and unwound for printing. Endless goods can advantageously be cut after printing to the desired length by means of a cutting device. It is possible to print several twisted pair lines next to each other on the same substrate and then to cut them into several individual strips by means of a longitudinal cutting device. Each strip may then comprise a single or multiple twisted pair leads.

The first and second line sections are the twisted-pair line or, in the manufacturing process, an electrically non-conductive layer, also referred to herein as the first non-conductive layer, is deposited. This layer can, for. B. laminated, sprayed or preferably printed, in particular with one of the methods described herein, such. B. the inkjet printing process. Thus, the first and second line sections are preferably arranged in a common plane between the substrate and the electrically non-conductive layer. As a material for an electrically non-conductive layer, inter alia electrically non-conductive ink or films having a layer thickness of preferably 0.03 mm to 0.3 mm can be used.

At least two or exactly two areas are formed per first line section and per second line section, which remain free or uncovered by the first non-conductive layer. For each first line section and each second line section, a first area and a second area remain free of the electrically non-conductive layer. The first area and the second area of each first and second line sections are separated from each other by the first non-conductive layer. The first and second regions are preferably windows surrounded by the electrically non-conductive layer.

As the material from which the first and second line sections are formed, applied, in particular printed or be such. B. with the inkjet printing process. The material is preferably in the same plane as the first non-conductive layer. This additional electrically conductive material forms the connection between the underside and the top of the first non-conductive layer. This additional material arranged in the first and second sections, in particular the layer, can be referred to as the climber. It is advantageous to print the climbers, for example, instead of producing by subsequent through-contacting. It is generally preferred that additional electrically conductive material be printed in the first and / or second regions, in particular by means of inkjet printing, which is located in the same plane as the first electrically non-conductive layer and / or has approximately the same layer thickness as the first electrically non-conductive layer. In particular, it is preferred that the additionally printed electrically conductive material, after the first and / or second line section has been printed, is printed on the first and / or second line section, wherein subsequently the first connection section and the second connection section are printed.

For example, the additionally printed electrically conductive material can be printed during the printing of the first line sections and / or the second line sections. Subsequently, the first non-conductive layer can be applied to the first and second line sections.

The additionally printed electrically conductive material may be printed on the first and / or second line section after the first and / or the second line section have been printed. The electrically conductive material may thus be a layer in addition to the line section on which it is arranged. In this optional embodiment, the electrically conductive material may be applied before, during or after the application of the electrically conductive layer in the first or second regions. The additionally printed electrically conductive material may alternatively be printed during the printing of a first connection portion and / or a second connection portion. Preferably, a plurality of first connecting sections and preferably a plurality of second connecting sections are or are printed onto the first non-conductive layer, in particular by means of one of the printing methods mentioned herein, preferably the inkjet printing method. The first connection portion or each of the first connection portions is or is printed so that it connects the first region of one of the first line sections with the second region of a particular nearest other of the first line sections electrically conductive. The same applies mutatis mutandis to the second connection portions, that is, that the second connection portion or each of the second connection portions electrically conductively connects the first region of one of the second line sections with the second region of a particular nearest other of the second line sections. The first connection sections preferably each cross over a second line section, and the second connection sections preferably each cross over a first line section.

The first and second connecting portions may be elongated, in particular strip-shaped, configured and in particular transversely or obliquely to the extension line along which the twisted pair line extends, be arranged, in particular with a second inclination angle. The second inclination angle is the angle between the longitudinal axis of the connecting portion and the extension line. The first inclination angle and the second inclination angle may be the same or different in magnitude, wherein it is preferable that the second inclination angle is opposite to the first inclination angle. Preferably, the first connecting portions are parallel to each other and the second connecting portions are parallel to each other. In particular, the first connecting portions and the second connecting portions are also parallel to each other. The first and second connection portions are printed on the first non-conductive layer such that a first connection portion and a second connection portion are alternately arranged, in particular in the extension direction of the twisted pair line or along the extension line. In other words, a first connection section is arranged between two second connection sections, and / or a second connection section is arranged between two first line sections. The first connection portions are electrically connected to the second connection portions separated and / or may in particular be arranged completely in a common plane.

In preferred embodiments, before, after or during the printing of the connecting portions, an electrically non-conductive layer, in particular (second) separation layer, on the first non-conductive layer and / or between the first and second connecting portions, in particular with the same layer thickness and / or in the same Level as the first and second connection sections are printed.

Another electrically non-conductive layer, also referred to herein as the second non-conductive layer, may be or may be applied to the first and second interconnecting portions. Thus, the first and second connection portions may be disposed between the first non-conductive layer and the second non-conductive layer. The second nonconductive layer can in particular be printed by means of one of the methods described herein, in particular by the inkjet printing method. Alternatively, the second non-conductive layer z. B. laminated or sprayed. On the second non-conductive layer and / or the underside of the substrate may, for.

With the described manufacturing method, a particularly band-shaped or / and flexibly deformable twisted-pair line is advantageously obtained, which is simple and inexpensive to produce. Changes in the geometry of the first and second conductors require no costly retooling, but can be carried out flexibly and easily with the inkjet printing method advantageous in this context. Of course, the individual layers, in particular the first and / or second electrically non-conductive layers and / or electromagnetic shielding layer can be produced by means of spraying or dipping. If the twisted-pair cable is band-shaped, it can be or printed over its entire width with first and second line sections. Alternatively, an edge may be formed in each case between the first and second line sections and the left and / or right outer edge. In preferred embodiments, the first conductor and the second conductor may be exposed at one end of the twisted pair line or at both ends of the twisted pair line from the electrically non-conductive layer (s) surrounding the first and second conductors , Thus, the first and the second conductor can be exposed at one end, ie be accessible from the outside, so that they can be contacted in a following step in a simple manner with other components, such as can be plugged together. For example, a first connection section and a second connection section or a first line section and a second line section are exposed at one end of the twisted pair line. At the opposite end of the twisted pair line, the first and second conductors may also be exposed as described herein.

Preferably, the twisted pair cable described herein is used in a bus system or information system, in particular a vehicle, preferably a motor vehicle.

In preferred embodiments, in addition to the pair of conductors comprising the first and second conductors, a further pair of conductors may be arranged, or may have been, manufactured according to the method described herein.

In preferred embodiments, the method for producing the twisted-pair line can be summarized by first printing oblique strips, namely the first and second conductor sections, by means of an electrically conductive ink onto a non-conductive substrate wherein an insulation is applied to the remaining surface of the strips. Subsequently, the according to the strip associated climbers, in particular by means of connecting portions, connected so that a first conductor and a second conductor, which are arranged with respect to each other twisted, are formed. The manufacturing process is not limited to the production of a twisted pair cable. For example, with the printing method according to the invention, in particular inkjet printing method further components can be applied to the substrate, such as at least one example, integrated circuit or electrically or electronically and / or mechanically active or passive components.

It goes without saying that the additionally applied components can be electrically connected to the twisted-pair line according to the invention, in particular can be supplied with electrical signals.

The invention has been described with reference to several preferred embodiments. In the following, advantageous embodiments will be described with reference to figures. The features disclosed herein form the subject matter of the independent claims individually and in any combination of features, even with the preceding description advantageous further. Show it:

FIG. 1 shows a substrate with first and second line sections arranged thereon, FIG. 2 shows the component from FIG. 1 with one on the first and second line sections

FIG. 3 shows the component from FIG. 2 with first and second connecting sections of the first and second conductors applied to the electrically insulating layer,

FIG. 4 shows the component from FIG. 3 with a second electrically insulating layer applied to the connecting sections in a first embodiment,

FIG. 5 shows a modified embodiment of FIG. 4, FIG. 6 shows the component from FIG. 4 or FIG. 5 with an electromagnetic shield applied to the second electrically insulating layer and FIG

FIG. 7 shows the component from FIG. 6 with a third electrically insulating layer applied to the shield.

Figure 1 shows an electrically non-conductive, strip-shaped, elongated substrate 30, on which, in particular on its upper side, a plurality of line sections 11 of a first conductor 10 and a plurality of second line sections 21 of a second conductor 20 are arranged in an alternating order. The line sections 11, 21 are elongated and strip-shaped and extend obliquely to the longitudinal direction, which corresponds to the extension direction, in which the twisted-pair line 1 or the pair of conductors 10, 20 extends are arranged. The first and second line sections 11, 21 are arranged parallel to each other. The first line sections 11 are electrically separated from the second line sections 21 via a partition 80. The width of the separation 80 is less than the width of the conduit sections 11, 21, resulting in a tightly packed configuration. The separation 80 disposed between the first conduit sections 11 and the adjacent second conduit section 21 (s) may be e.g. have an electrically non-conductive layer which is in the same plane and has the same layer thickness as the line sections 11, 21. The electrically non-conductive substrate 30 is a thin plastic film made of polyester in the example shown. The first and second lead portions 11, 21 are printed on the substrate 30 by an ink jet printing method, and are formed by an electroconductive ink which is dried or cured after printing. The likewise strip-shaped separation 80 is formed by an electrically non-conductive ink, which is printed on the substrate 30 during printing of the first and second line sections 11, 21 and also printed after printing, e.g. dried or cured.

In a further step, as shown in Figure 2, an electrically insulating, ie non-conductive first layer 40 applied to the first and second line sections 11, in particular printed electrically non-conductive ink with the inkjet printing process. The first line sections 11 and the second line sections 21 are not completely printed with the first layer 40. Rather, each first line section 1 1 a first region 12 and a second region 13 are released from the first layer 40. The same applies to the second line sections 21, ie that each second line section 21, a first region 22 and a second region 23 remain free of the first layer 40. The first region 12, 22 is located at one end of the conduit section 11, 21 and the second region 13, 23 is located at the other end of the conduit section 11, 21. Instead of the first layer 40, the first and second regions 12, 22 ; 13, 23 another layer of electrically conductive ink is printed on the first line sections 11 and the second line sections 21, in particular during the printing of the first non-conductive layer 40. The thus formed additional electrically conductive layer in the areas 12, 22, 13, 23 is located in the plane as the first non-conductive layer 40. In the areas 12, 22, 13, 23 thus so-called climbers are formed.

An end 2 of the not yet finished twisted-pair line remains free of the layer 40, so that at this end the first line section 11 and the second line section 21 are exposed.

At the opposite end 3, on the other hand, the first and second line sections 11, 21 are printed with the layer 40 so that they are not exposed except for the areas 13, 22. It should be noted that the end 3 may be formed like the end 2 or the end 2 as the end 3.

Referring to Fig. 3, there is shown the device of Fig. 2, in which one of the first conductive portions 11 and the second region 13 of another of the first conductive portions 11 with the electrically conductive ink and the inkjet process is applied to the first non-conductive layer 40 and the first region 12 a first connection portion 14 is printed so that the region 12 is electrically connected to the region 13. As a result, the first line sections 11 can be electrically connected to the respectively next first line section 11. The same applies mutatis mutandis to the second connecting portions 24. On the first non-conductive layer 40 and the first region 22 of one of the second line sections 21 and the second region 23 of another of the second line sections 21 with the electrically conductive ink and the inkjet printing method, a second connecting portion 24 is printed, so that the area 22 is electrically connected to the area 23. Thereby, the second line sections 21 can be electrically connected to the next-following second line section 21, respectively.

Thus, first connection portions 14 in the extension direction of the conductor pair 10, 20 are arranged alternately with second connection portions 24.

Between the first connecting portions 14 and the adjacent second connecting portion 24, a partition 90, which is e.g. has an electrically non-conductive layer that is in the same plane and the same layer thickness as the connecting portions 14, 24th

In the embodiment of FIG. 4, a second electrically insulating layer has been applied to the component shown in FIG. H. to the first and second connecting portions 14, 24. The electrically insulating layer 50 has been laminated in the example shown in FIG. Alternatively, the electrically conductive layer 50 may be printed as shown in Figure 5, in particular with an electrically non-conductive ink and the inkjet printing process.

As is apparent from FIGS. 4 and 5, the substrate 30 or the first and second conductors 10, 20, in particular a first connection section 14 and a second connection section 24 or a first line section 11 and a second line section 21, are freed from the second non-conductive layer 50 , This allows contacting, such. B. a plug connection with another component which is connected to the twisted pair line 1.

FIG. 6 shows a shielding 60, which is optionally applied to the second non-conductive layer 50 shown in FIGS. 4 and 5, which serves for the electromagnetic shielding, which is advantageously also applied to the underside of the substrate 30. In this case, the shielding 60 applied to the second nonconductive layer 50 and to the underside of the substrate 30 can be connected to one another in an electrically conductive manner, for example. Although such a shield 60 could basically be laminated or applied by dipping or spraying, it is preferably printed, namely with electrically conductive ink and the inkjet printing process described herein. Finally, as shown in Figure 7, the shield 60 is provided with a third electrically non-conductive layer 70, which is printed on the shield 60, in particular by applying an electrically non-conductive ink, preferably with the ink printing method described herein.

The thus obtained twisted-pair cable 1 is flexibly deformable and is therefore particularly suitable for use in a motor vehicle or another of the applications described herein.
