Technical Field

The present invention relates to a cable or a connector device having a cable.

Background

In the field of power transmission, there is a need to provide a cable having better electrical characteristics.

Disclosure of Invention

On this background, the problem to be solved by the present invention is to provide a cable with better electrical characteristics.

According to the invention, this problem is solved by an assembly having the features of claim 1.

Thus, there is provided:

a cable connectable at one end to a connector, the cable having at least two cores, a jacket, an insulator formed between the cores and the jacket, and having a sleeve formed at the end of the cable, wherein the sleeve comprises a first region having an elliptical cross-section and a second region having a substantially circular cross-section.

Due to the at least two cores being arranged side by side to each other, the sheath surrounding the cores defines an oval cross-section. In order to increase the retention of the sleeve on the sheath, the invention proposes to adapt the sleeve to the contour or cross section of the sheath braid in the region where the sleeve is to be connected to the sheath.

Since the cable with the bushing is usually connected to the outer conductor with a circular cross-section in a further processing step, the invention also proposes to provide a substantially circular cross-section in the second region of the bushing.

In this application "elliptical" means that the extension in a first direction is larger than the extension in a second direction, wherein the second direction is perpendicular to the first direction.

By substantially circular cross-section is meant a circular cross-section that may have a gap in the axial direction.

The oval cross-section may be substantially in the shape of an oval hole, for example, with the short sides being formed by semi-circles and the long sides connecting the short sides. The term oval shaped hole does not exclude a notch in the long side.

With reference to the drawings, preferred embodiments and modifications will emerge from the other dependent claims and the description.

The features mentioned above and those yet to be explained below can of course be used not only in the combination specified, but also in other combinations or alone without departing from the scope of the invention.

According to a preferred development of the invention, the first region is formed at a first end of the sleeve on the connector side, and the second region is formed at a second end of the sleeve opposite the first end. Thus, the present invention can be applied to a cable having cores arranged adjacent to each other and forming an oval cross section. But of course the invention can also be applied to cables having cores arranged in a circular cross-section. It can thus alternatively be provided that the sleeve has a circular cross-section at the end on the connector side and an oval configuration at the opposite end.

According to a preferred development of the invention, the sleeve jacket is formed and the connector-side end of the jacket is folded over the sleeve, wherein the folded-over jacket extends in particular behind the sleeve. In this case, it is also ensured that the turned-over sheath adheres better to the sleeve.

Due to the sleeve shape, the sheath folded over the support sleeve is guided such that the air pocket between the outer conductor and the cable core is reduced, thereby reducing electrical defects. The first region of the sleeve is shaped such that the jacket of the conductor is brought into a defined position, in particular a contour-following position, with respect to a single core of the cable and the outer conductor of the connector.

According to a preferred development of the invention, at least two cores are twisted together. In this case, it will also be referred to as a so-called "twisted pair" cable. The present invention has a particularly advantageous effect on "twisted pair" cables because, for conventional oval ferrules, slight manufacturing tolerances are created when assembling the ferrule onto the jacket. Problems often arise if the sleeve is twisted slightly relative to the cable during assembly. This problem can be alleviated by the second region having a circular, i.e. rotationally symmetrical, cross-section.

According to a preferred development of the invention, the first region comprises two U-shaped brackets arranged opposite each other. Thus, the sleeve may be interrupted in the first region. This has a particularly advantageous effect with respect to the manufacturability and production cost of the bushing. Alternatively, the first and second regions are different cross-sectional sleeves with an offset between the first and second regions.

In this case it can be provided that the U-shaped brackets are deformed in the processing step, for example due to crimping, so that they touch or overlap one another.

According to a preferred development of the invention, the sleeve has a recess along the contour facing the sheath. Thus, a gap is formed between the two cores at the top or bottom side. In this way, the electrical properties of the cable are improved in the region of the sleeve.

Of course, as described above, the present invention is also applicable to a connector apparatus having a connector and having a cable. In this case, the end of the cable on the connector side is connected to the connector by crimping the outer conductor of the connector apparatus with the cable.

But of course the invention is applicable to all connection options for cables. Thus, one cable may also be connected to another cable, or for example to a radio module.

According to a preferred development of the invention, it is expedient if the sleeve, the sheath and the outer conductor are pressed together in the first region.

Alternatively or additionally, it is advisable that the sleeve, the outer conductor and in particular the jacket are pressed together in the second region.

Of course, it is particularly advantageous to crimp the sleeve, the jacket and the outer conductor together in both the first and second regions. The crimp in the first region can thus be advantageously designed for the holding force of the sheath on the sleeve, and the crimp in the second region can be particularly advantageously designed for the outer conductor and the sleeve.

The above configurations and modifications may be combined with each other in any meaningful way. Other possible configurations, modifications and embodiments of the invention also include combinations of features of the invention described above which are not explicitly mentioned, or combinations of features described below with respect to the exemplary embodiments. In particular, the person skilled in the art is also able to add various solutions as modifications or additions to the specific basic form of the invention.

Detailed Description

Fig. 1 shows a sleeve 18 for mounting on a cable 10 according to one embodiment of the invention. The sleeve 18 includes a first region 20 having an elliptical cross-section. The oval cross-section is formed substantially as an oval hole by two oppositely arranged U-shaped brackets 30, 31. Between the brackets 30, 31, the sleeve 18 is interrupted by gaps 34, 35, that is, in the non-crimped state, the opposite ends of the brackets 30, 31 do not contact each other. The sleeve 18 also includes a second region 22 having a substantially circular cross-section. Essentially means that the second region 22 is only approximately circular in cross-section and has a notch 32 at its top side. In the installed state, the gap 32 is located at a point between the two cores 12.

Thus, in fig. 1, a first region 20 having an oval cross-section is formed at a connector-side first end 24 of the ferrule 18. The second region 22 of the sleeve 18 is formed at the opposite end 26 of the cable side of the sleeve.

The first region 20 of the sleeve 18 is connected to the second region 22 of the sleeve by two webs 36, 37. In this case, the web 36 connects the U-shaped bracket 31 to the second region 22 of the sleeve. The web 37 connects the bracket 30 to the second region 22 of the sleeve.

Fig. 2 shows the sleeve 18 of fig. 1 in a side view.

Fig. 3 shows the sleeve 18 of fig. 1 and 2 in a further side view, the sleeve 18 in the side view of fig. 3 being rotated by 90 degrees relative to the side view of fig. 2.

Fig. 4 shows cable 10 with sleeve 18 mounted thereon. The cable comprises two cores 12 surrounded by an insulator 16 or 17, respectively. The insulating cores 12 are surrounded by a common sheath 14. The jacket 14 forms the outer conductor of the cable, which protects the core 12 from external electromagnetic influences.

The jacket 14 of the cable 10 originally extends between two oppositely disposed ends of the cable 10. However, during further processing of the cable 10, the jacket 14 is folded outwardly over the sleeve 18 such that the jacket 14 extends from one end of the cable 10 to the connector-side end 24 of the sleeve, where the jacket 14 is folded outwardly over the sleeve 18. Here, the folded-over sheath extends behind the sleeve 18, in particular towards the other side of said sleeve 18 opposite the connector side.

Fig. 5 shows the cable 10 of fig. 4 in a side view, the side view of fig. 5 being rotated 90 degrees relative to the side view of fig. 4.

As can be seen in connection with fig. 4 and 5, the jacket 14 bears between the sleeve 18 and the core 12 on the cross-section formed by the two cores 12. Thus, the sheath 14 also encloses an elliptical cross-section.

Fig. 6 shows in a side view a connector device 50 with the cable 10 shown in fig. 4 and 5. As can be seen from fig. 4 and 6, in the first region 20 of the bushing, the jacket 14 or the outer conductor 52 does not rest optimally on the cable. However, since the sleeve 18 bears against the core 12 in this region, possible negative electrical effects resulting therefrom can be reduced or compensated for.

Fig. 7 shows the connector device 50 of fig. 6 in a side view, the side view of fig. 7 being rotated 90 degrees with respect to the side view of fig. 6.

As can be further seen in conjunction with fig. 4 to 7, the outer conductor 52 or the jacket 14 rests against the sleeve 18 in the second region 22.

Although the present invention has been fully described above by way of preferred exemplary embodiments, the present invention is not limited thereto but may be modified in various ways.
