Technical Field

The invention relates to a guide element for a cell line in a cable.

Background

EP 2697804B 1 discloses a star-quad twisted cable.

US 5483020 a discloses a cable comprising cores arranged as Parallel pairs ("parallell Pair" cable).

Disclosure of Invention

On this background, it is an object of the present invention to provide a combination of star quad cables and "parallel pair" cables.

The solution of the invention to achieve the object is an assembly having the features of claim 1 and/or a method having the features of claim 10.

Accordingly, the following steps are proposed:

a guide element for an electrical core in the cable, having four guide rails for each electrical core of the cable, wherein the guide rails extend such that at a first end of the guide element at least two cores are transposed compared to a second end of the guide element opposite the first end; and

a cable with at least four cores, which in a first section adopt a star-quad twisted arrangement and in a second section are parallel pairs, wherein the cable between the first section and the second section has a guiding element by means of which the cores are transferred from the star-quad twisted arrangement to the arrangement as parallel pairs.

The basic idea of the invention is to provide a guiding element which guides the core wires of the cable in such a way that at least two core wires exchange positions in the cable.

In the present application, the term "plug connector configuration" refers to a cable connected with a plug connector.

The basic idea of the invention is also: switching from a star four wire lay out of cores in the cable to a lay out of cores as parallel pairs. The specific way to realize the layout switching is as follows: the two cores of the cable exchange positions. The guide element guides the transposition.

The position of the core is the position of the core relative to the other cores of the cable. For example, a quad cable has four positions, such as upper right, lower right, upper left, lower left, or right side out, right side center, left side out.

A star-quad twisted cable, i.e. a cable comprising cores in a star-quad twisted arrangement, belongs to symmetric cables. In this cable, four core wires are twisted with each other in a cross shape. Accordingly, in the cross section of the star quad twist, four cores are arranged at the corners of a square, with the cores of one pair being arranged at diagonally opposite corners. By means of the pairs of cores being mutually perpendicular thereby, a desired high crosstalk attenuation from one pair of cores to the other is produced. In addition to the mechanical stabilization of the arrangement of the conductors relative to one another, a further advantage of the star quad twisting is that the compression density is higher than the pair twisting.

In the parallel pair arrangement, the core wires are not arranged in pairs in a diagonally opposite manner, but are arranged in pairs side by side. The core pairs of a "parallel pair" cable are typically shielded by core pair shielding.

Advantageous embodiments and further aspects are described with reference to the other dependent claims and with reference to the drawings.

It is understood that the features mentioned above and those yet to be explained below can be combined in the manner given in the present application, but also in other combinations or applied separately within the scope of the invention.

According to a preferred further development of the invention, the guide element introduces a four-wire twisted arrangement of the core/plug contacts into a parallel-pair arrangement. This enables the combination of a star quad twisted cable/jack connector or "parallel pair" cable/jack connector with a "parallel pair" cable/jack connector. Whereby the advantages of both systems can be utilized or combined with each other.

According to a preferred further development of the invention, the guide rail is constructed at the first end of the guide element right above, right below, left above and left below. It will be appreciated that the guide rails may adopt different arrangements in the region of the crossing of the guide elements in order to achieve a transposition of the core wires. This arrangement is particularly compact.

According to a preferred further development of the invention, the guide rail is designed such that a change from the right core to the left core and from the left core to the right core or a change from the upper core to the lower core and from the lower core to the upper core is made. It will be understood that with symmetrical guide elements, the expression "right/left" or "up/down" may be the same except for twisting.

According to a preferred further development of the invention, the guide element has means for compensating for length deviations. The length deviation is generated by the difference in length between the individual cores. Accordingly, the length of the core wire in which the transposition occurs may be different from the remaining core wires. Correspondingly, the guide rail of the core wire which is not transposed can be extended manually compared to the guide rail of the core wire which is transposed, for example: the guide rail of the core wire without transposition has certain curvature, so that the guide rail is extended to the length same as that of the guide rail of the core wire with transposition.

According to a preferred further development of the invention, the guide element has a shielding element on the first end and/or on the second end. This improves the shielding of the core in the region of the guide element.

Wherein the shielding elements are preferably cross-shaped and may be arranged centrally between the core wires. This also improves the mutual shielding of the wires in the region of the guide elements.

According to a preferred further development of the invention, the guide elements can be mounted in different orientations, in particular in eight orientations. Accordingly, the guide rails can be constructed rotationally symmetrically to one another. This simplifies the installation of the guide element, since this prevents the guide element from being installed in reverse. This is particularly helpful for robot-assisted mounting.

According to a preferred further development, the guide element has a recess on one side, in particular a recess on each of two opposite sides. This achieves a particularly simple and efficient fixing or snap-in member of the guide element.

According to a preferred further development of the invention, the guide element has a wall which is vertically formed between the guide rails for aligning the core wire. It will be appreciated that the wall may be interrupted in the region of the intersection of the transposed cores. This further improves the mutual shielding of the wires in the region of the guide elements.

According to a preferred further development of the invention, the at least two cores, in which the transposition takes place, cross in a crossing region.

In this case, it is particularly preferred that the guide element also has at least one, in particular two, shielded regions in which the wires are shielded from one another by the guide element, and in particular that the at least two transposed wires are not shielded from one another by the guide element in the crossing region.

The shielding results in an improved electrical characteristic of the guiding element. Accordingly, a guiding element comprising a shielded area may be applied in a transmission line having a higher transmission rate.

In this case, it is particularly preferred that the guide element is designed to have as long a shielded region as possible. This minimizes impedance interference due to unshielded sections.

In the case of shielding the two transposed conductors from each other in the crossing region by a separate outer conductor, in particular by an outer conductor film, the electrical properties can be further improved. In the intersection region, both construction and production costs are high in order to achieve shielding of the intersection region. However, the manufacture of the guide element is simplified in the case of cores which are not shielded in the crossing region. The shielding of the core may also be achieved in this case by other means, such as an outer conductor film. In this way, the electrical properties can be improved similarly compared to a solution of the guide element comprising a shielded intersection region.

According to a preferred development of the invention, the guide rail extends such that at the first end of the guide element, the two wires are not transposed with respect to the second end, wherein the guide rail has a particular shape such that the two wires which are not transposed are shielded over the entire length of the guide element.

In this way, the conductor, which is not transposed, can be shielded without high construction and production expenditure.

Within reasonable limits, the above technical solutions and further solutions can be combined with each other at will. Other possible solutions, further solutions and embodiments of the invention also include combinations of features of the invention not explicitly mentioned in the foregoing or in the following description with reference to the examples. In particular, those skilled in the art will also propose modifications or additions to the basic form of the invention, in particular also in an independent aspect.

The drawings are described more fully below in general terms.

Detailed Description

Fig. 1 to 3 are each a perspective view of a guide element 10 for four electrical conductors. Accordingly, the guide element 10 has four guide rails 12.1, 12.2, 12.3, 12.4 for each electrical conductor.

The guide rails 12.1 and 12.2 extend such that between the first end 14 and the second end 16 the layout of the cores 102.1 and 102.2 of the guide rails 12.1 and 12.2 is interchanged with the layout of the cores 102.3 and 102.4 of the guide rails 12.3 and 12.4.

The guide rails 12.4 and 12.3 have a curvature to compensate for length deviations due to the transposition of the core wires 102.1 and 102.2. The bend is a member 18 for compensating for length deviations.

The guide element 10 has a shielding element 20 at each of the first end 14 and the second end 16. The shielding elements are designed as star-shaped extensions and insulate the wires 12.1, 12.2, 12.3, 12.4 from one another in the region of the first end 14 or the second end 16. Based on the star-shaped extension, an optimized transition from the cable arrangement to the guiding element is achieved. Thereby controlling the mechanical extension of the core and ensuring shielding in the transition region. Furthermore, the guide element enables impedance control and shielding in the region of the guide element.

While the invention has been fully described in connection with the preferred embodiments, it is not limited thereto but may be modified in various ways.

The guide element 10 has two opposite lateral grooves 22. The groove serves to fix the guide element in the plug connector configuration. For example, a solution with an insulating element snapped into the recess may be used.

Fig. 4 shows a plug connector arrangement comprising a cable 100 and a plug connector 200. Cable 100 is constructed as a "parallel pair" of cables. Accordingly, the cores 102.1 and 102.3 or 102.2 and 102.4 form a pair in the cable, respectively. Both pairs are shielded by a core pair shield 108. The core-pair shield 108 is constructed as a thin film. The cable-side region of the cable 100 opposite the guide element 10 forms a section 104.

Fig. 4 is a perspective view of the plug connector arrangement from above. It will be understood that the orientations "up" and "down" may be interchanged.

Fig. 5 is a perspective view from below of the plug connector arrangement.

A guide element 10 is provided in the region of the stripped insulation of the cable 100. It can be seen that the wires 102.1 and 102.2 cross in the guide element 10. Accordingly, at the plug-connector-side end of the guide element 10, the cores 102.1 and 102.3 or 102.2 and 102.4 respectively form pairs, the members of which are diagonally opposite. The plug-connector-side region of the cable 100 opposite the guide element 10 or the plug connector 200 forms a section 106 of the plug connector arrangement.
