DESCRIPTION OF EXEMPLARY EMBODIMENTS

(12) FIG. 1 shows a sleeve 18 for mounting on a cable 10 according to one embodiment in accordance with the present disclosure. The sleeve 18 comprises a first region 20 with an oblong cross-section. The oblong cross-section is formed roughly as an oblong hole by two oppositely situated U-shaped brackets 30, 31. Between the brackets 30, 31, the sleeve 18 is interrupted by gaps 34, 35, i.e., opposite ends of the brackets 30, 31 do not touch each other in a non-crimped state. The first region may comprise flaps 38. Flaps 38 may constitute the shanks of the U-shaped brackets 30, 31. As such, the sleeve 18 may comprise at least four flaps 38. The sleeve 18 moreover comprises a second region 22 with a substantially round cross-section. Substantially means that the cross-section of the second region 22 is only approximately round and has an indentation 32 at its top side. The indentation 32 is located at a point which is situated between two conductors/cores 12 in the mounted state.

(13) Accordingly, in FIG. 1 the first region 20 with the oblong cross-section is formed at a first end 24 of the sleeve 18 with the connector. The second region 22 of the sleeve 18 is formed at the opposite end 26 of the sleeve with the cable.

(14) The first region 20 of the sleeve 18 is connected to the second region 22 of the sleeve by two cross-pieces 36, 37. In this case, cross-piece 36 connects the U-shaped bracket 31 to the second region 22 of the sleeve, e.g. at a central portion of the U-shaped bracket 31. Cross-piece 37 connects the bracket 30 to the second region 22 of the sleeve.

(15) FIG. 2 shows a sleeve 18 of FIG. 1 in a side view.

(16) FIG. 3 shows a sleeve 18 of FIG. 1 and FIG. 2 in a further side view, the sleeve 18 in the side view of FIG. 3 being rotated with respect to the side view of FIG. 2 by 90.

(17) FIG. 4 shows a cable 10 on which a sleeve 18 has been mounted. The cable comprises two cores 12, which are respectively enclosed by an insulator 16 or 17. The insulated cores 12 are enclosed by a common shield 14. The shield 14 forms an outer conductor of the cable, which shields the cores 12 against external electromagnetic influences.

(18) The shield 14 of the cable 10 originally extended between two oppositely situated ends of the cable 10. However, in the course of further processing of the cable 10, the shield 14 has been turned back over the sleeve 18, such that the shield 14 extends from one end of the cable 10 to the end 24 of the sleeve with the connector and is turned back over the sleeve 18 at the end 24 of the sleeve with the connector. Here, the turned-over shield extends to behind the sleeve 18.

(19) FIG. 5 shows a cable 10 of FIG. 4 in a side view, the side view of FIG. 5 being rotated with respect to the side view of FIG. 4 by 90.

(20) From a joint viewing of FIGS. 4 and 5 it will be noticed that the shield 14 lies against the cross-section, formed by the two cores 12, between the sleeve 18 and the cores 12. Accordingly, the shield 14 also encloses an oblong cross-section.

(21) FIG. 6 shows a connector arrangement 50 having a cable 10 as per FIG. 4 and FIG. 5 in a side view. It can be seen from FIG. 4 and FIG. 6 that the shield 14 or the outer conductor 52 do not lie optimally against the cable in the first region 20 of the sleeve. However, possible negative electrical effects resulting from this can be mitigated or compensated for in that the sleeve 18 lies against the cores 12 in this region.

(22) FIG. 7 shows a connector arrangement 50 of FIG. 6 in a side view, the side view of FIG. 7 being rotated with respect to the side view of FIG. 6 by 90.

(23) From a joint viewing of FIGS. 4-7 it will be further noticed that the outer conductor 52 or the shield 14 lie against the sleeve 18 in the second region 22.

(24) Although the present invention has been fully described above with the aid of preferred exemplary embodiments, it is not limited to them, but rather can be modified in various ways.
