Description

FIELD OF THE INVENTION

The present invention relates to a guide element for electrical wires in a cable.

TECHNICAL BACKGROUND

The EP 2697804 B1 shows a star quad cable.

The US 5483020 A shows a cable with wires, which are arranged as a parallel pair ("parallel pair" cable).

SUMMARY OF THE INVENTION

Against this background, the present invention has for its object to provide a combination of star quad and "parallel pair" cables.

According to the invention, this object is achieved by an assembly having the features of claim 1 and / or by a method having the features of claim 10.

• ein Führungselement für elektrische Adern in einem Kabel mit wenigstens vier Führungsbahnen für jeweils eine elektrische Ader des Kabels, wobei die Führungsbahnen derart verlaufen, dass sich an einem ersten Ende des Führungselements ein Platzwechsel wenigstens zweier Adern gegenüber einem dem ersten Ende gegenüberliegenden zweiten Ende des Führungselements ergibt; sowie
• ein Kabel mit wenigstens vier Adern, welche in einem ersten Abschnitt in einer Sternvierer-Anordnung und in einem zweiten Abschnitt als parallele Paare geführt sind, wobei das Kabel zwischen dem ersten Abschnitt und dem zweiten Abschnitt ein Führungselement aufweist, mittels welchem die Adern von der Sternvierer-Anordnung zu einer Anordnung als parallele Paare überführt werden.

Accordingly, it is provided:

• a guide element for electrical wires in a cable with at least four guide tracks for each electrical wire of the cable, the guide tracks running such that at a first end of the guide element there is a change of location of at least two wires relative to a second end of the guide element opposite the first end ; such as
• a cable with at least four wires, which are guided in a first section in a star quad arrangement and in a second section as parallel pairs, the cable between the first section and the second section having a guide element, by means of which the wires from the star quad - Arrangement can be converted to an arrangement as parallel pairs.

The idea on which the present invention is based is to create a guide element which guides the wires of a cable in such a way that at least two wires change a place in the cable.

In this application, the term connector arrangement is understood to mean a cable connected to a connector.

The idea on which the present invention is based is furthermore to switch in a cable from a star quad arrangement of the wires to an arrangement of the wires as parallel pairs. This change of arrangement is achieved by changing two wires of the cable. The change of place is guided by the guide element.

A wire location means a position of the wire in relation to other wires of the cable. For example, a four-core cable has four places, for example, top right, bottom right, top left, bottom left or outside right, center right, center left, left outside.

A star quad cable, i.e. a cable with cores in a star quad arrangement, is one of the symmetrical cables. With this cable, four wires are twisted together in a cross shape. Accordingly, the four wires are in cross section the star quad at the corners of a square, the veins of a pair being arranged at diagonally opposite corners. As a result of the pairs of conductors which are perpendicular to one another, a desired high crosstalk attenuation results from one pair to the other pair. In addition to the mechanical stabilization of the arrangement of the conductors relative to one another, a further advantage of star quad stranding is a higher packing density than with pair stranding.

Cores in a parallel pair arrangement are not arranged diagonally in pairs, but arranged side by side in pairs. A wire pair of a "parallel pair" cable is often shielded by a wire pair shield.

Advantageous refinements and developments result from the further subclaims and from the description with reference to the figures of the drawing.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own without departing from the scope of the present invention.

According to a preferred development of the invention, the guide element converts a star-four arrangement of the wires / plug contacts into an arrangement of parallel pairs. Star quad cables / connectors or "parallel pair" cables / connectors and "parallel pair" cables / connectors can thus be combined. This means that the advantages of both systems can be used or combined with one another.

According to a preferred development of the invention, the guideways are at a first end of the guide element upper right, lower right upper left and lower left. It goes without saying that the guideways can be arranged differently in an intersection area of the guiding element in order to implement the change of location of the wires. This arrangement is particularly compact.

According to a preferred development of the invention, the guideways are designed such that the change of location takes place from a right-hand wire to a left-hand wire and a left-hand wire to a right-hand wire or from an upper wire to a lower wire and a lower wire to an upper wire , With symmetrical guide elements, it goes without saying that the information on the right / left or top / bottom can be identical except for rotation.

According to a preferred development of the invention, the guide element has means for compensating for a length offset. A length offset occurs due to a length difference between several wires. Accordingly, it is possible that the length of the space-changing wires differs from that of the other wires. Accordingly, it can be provided that the guideways of the non-space-changing cores are artificially extended compared to the guideways of the space-changing cores, for example in that the guideways of the non-space-changing cores are curved such that the guideways are extended to the same length as a guideway of a space-changing core.

According to a preferred development of the invention, the guide element has a screen element at the first end and / or at the second end. The shielding of the cores in the region of the guide element can thus be improved.

It is expedient if the shield element is cross-shaped and can be arranged centrally between the wires. The shielding of the wires from one another in the region of the guide element can thus also be improved.

According to a preferred development of the invention, the guide element can be mounted in different orientations, in particular in eight orientations. Accordingly, it can be provided that the guideways are rotationally symmetrical to one another. This facilitates the assembly of the guide element, since the guide element is thus not mounted the wrong way round. This is particularly advantageous in the case of robot-assisted assembly.

According to a preferred development of the invention, the guide element has a groove on one side surface, in particular a groove on each of two opposite side surfaces. A particularly simple and effective fastening means or latching means of the guide element is thus created.

According to a preferred development of the invention, the guide element has changes which are formed perpendicularly between the guide tracks for tuning the veins. It goes without saying that the walls can be interrupted in the crossing area of the space-changing wires. In this way, the shielding of the wires from one another in the region of the guide element is further improved.

According to a preferred development of the invention, the at least two wires, with respect to which the change of location results, intersect in an intersection area.

It is particularly expedient if the guide element also has at least one, in particular two, shielded areas, in which the cores are shielded from one another by the guide element, and in particular the at least two cores, with respect to which the change of location results, are not shielded from one another by the guide element in the crossing region.

The electrical properties of the guide element are improved due to the shielding. Accordingly, a guide element with a shielded area can be used in transmission links with higher transmission rates.

It is further advantageous if the guide element is designed in such a way that the shielded area is formed as long as possible. A fault point in the impedance due to an unshielded section can thus be minimized.

The electrical properties can be further improved by shielding the two wires, with respect to which the change of location occurs, from one another in the area of intersection by a separate outer conductor, in particular by an outer conductor foil. In the intersection area, shielding of the intersection area can be realized with great constructional and large manufacturing effort. However, the manufacture of a guide element is simplified if the wires in the crossing area are not shielded. In this case, the wires can be shielded by other means, such as an outer conductor foil. This ensures a similar improvement in the electrical properties compared to the variant of a guide element with a shielded crossing area.

According to a preferred development of the invention, the guideways run in such a way that at the first end of the guide element does not result in a change of location of two wires relative to the second end, the guide tracks being shaped in such a way that the two wires, with respect to which there is no change of location, are shielded over an entire length of the guide element.

Shielding of the non-space-changing cores can thus be provided without great design effort or production effort.

The above refinements and developments can, if appropriate, be combined with one another as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention described above or below with reference to the exemplary embodiments, which are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

Other embodiments and many of the advantages mentioned result from the drawings. The elements of the drawings are not necessarily shown to scale with respect to one another.

In the figures of the drawing, elements, features and components that are the same, have the same function and have the same effect — unless otherwise stated — are each provided with the same reference symbols.

The figures are described below in a coherent and comprehensive manner.

DESCRIPTION OF EMBODIMENTS

The Figures 1-3 each show a perspective view of a guide element 10 for four electrical wires. Accordingly, the guide element 10 has four guide tracks 12.1, 12.2, 12.3, 12.4, each for one electrical wire.

The guideways 12.1 and 12.2 run in such a way that the arrangement of the wires 102.1 and 102.2 of the guideways 12.1 and 12.2 with respect to the wires 102.3 and 102.4 of the guideways 12.3 and 12.4 is exchanged between the first end 14 and the second end 16.

The guideways 12.4 and 12.3 have a bend in order to compensate for the length offset due to the change in location of the wires 102.1 and 102.2. The bend is a means 18 for compensating the length offset.

The guide element 10 has a screen element 20 at the first end 14 and at the second end 16. The shielding element is designed as a star-shaped extension and shields the cores 12.1, 12.2, 12.3, 12.4 in the region of the first end 14 and the second end 16, respectively. The star-shaped extension ensures an optimized transition from the cable arrangement to the guide element. This controls the mechanical course of the wires and ensures shielding in the transition area. Furthermore, the guide element ensures impedance control and shielding in the area of the guide element.

Although the present invention has been completely described above on the basis of preferred exemplary embodiments, it is not limited to these but can be modified in a variety of ways.

The guide element 10 has two laterally opposite grooves 22. The grooves serve to fix the guide element in a connector arrangement. For example, it can be provided that an insulating part engages in the grooves.

The Figure 4 shows a connector arrangement with a cable 100 and a connector 200. The cable 100 is designed as a "parallel pair" cable. Form accordingly the wires 102.1 and 102.3 or 102.2 and 102.4 in the cable each a pair. Both pairs are shielded by a wire pair shield 108. The core pair screen 108 is designed as a film. The area of the cable 100 opposite the guide element 10 forms the section 104.

Figure 4 shows a perspective view from above of a connector assembly. It goes without saying that the orientation "top" or "bottom" can be interchanged.

Figure 5 shows a perspective view from below of a connector assembly.

The guide element 10 is located in a stripped area of the cable 100. It can be seen that the wires 102.1 and 102.2 intersect in the guide element 10. Accordingly, the wires 102.1 and 102.3 or 102.2 and 102.4 each form pairs at the connector-side end of the guide element 10, the partners of which are opposite each other diagonally. The area of the cable 100 or the connector 200 opposite the guide element 10 on the connector side forms the section 106 of the connector arrangement.
