Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] An exemplary embodiment of the invention is illustrated in the drawings and will be explained in detail below.

[0017] FIG. 1 shows an illustration from the side of an insulating body;

[0018] FIG. 2 shows an illustration of an insulating body in a view of the interior side;

[0019] FIG. 3 shows an illustration of a high-power plug connector system with three inserted insulating bodies;

[0020] FIG. 4 shows an illustration of a cable connection housing of a high-power plug connector system.

DETAILED DESCRIPTION

[0021] The drawings contain partly simplified schematic illustrations. Identical reference symbols are partly used for the same but possibly not identical elements. Different views of the same elements could be to a different scale.

[0022] Specifications of directions such as, for example, “left”, “right”, “above”, and “below” are to be understood with reference to the respective drawing and can vary in the individual illustrations with respect to the object illustrated.

[0023] FIG. 1 shows an insulating body 1 in a side view. FIG. 2 shows the insulating body 1 in a view from an interior side 11 in the direction of a stop shape 12. The structure here provides an essentially hollow cylindrical shape which has a plug connector side 10 and the interior side 11. The plug connector side 10 and the interior side 11 are here separated by the stop shape 12. In the exemplary embodiment shown, the stop shape 12 is configured as a circumferential ring. At least one retaining shape 13 is situated close to the stop shape 12 on the interior side 11. In the embodiment shown, three retaining shapes 13 are integrally formed on the interior side 11 of the insulating body 1. The retaining shapes 13 are here arranged so that they are offset circumferentially by essentially 120°, which is particularly clear in the view in FIG. 2. The interior side 11 furthermore has a corrugated shape 14 which is designed to advantageously enlarge air gaps and creepage distances in the interior 8 of a cable connection housing 4. The corrugated shape 14 is essentially several rings integrally formed circumferentially. The corrugated shape 14 is here shaped particularly expediently with at least two rings, even better with at least four rings, or ideally, as in the case illustrated, at least six rings. Lastly, the embodiment shown also provides a recess 15 which enables an electrically conductive busbar 3 arranged in the cable connection housing 4 to be capable of being brought into engagement with a high-power plug contact 5 inserted into the insulating body 1 in a particularly space-saving fashion.

[0024] FIG. 3 shows the interaction of different components of a high-power plug connector system 2. First, the cable connection housing 4 can be seen here. Such a cable connection housing 4 is usually a metal housing, at least the majority of which is painted. An insulating shell 6 can be seen in an interior 8 shaped in the cable connection housing 4. Three insulating bodies 1 with high-power contacts 5 inserted therein project into the interior 8. The high-power contacts 5 have a plane region to which the electrically conductive busbar 3 can be applied. Threaded openings on the high-power contacts 5 enable the busbar 3 to be fixed by means of fastening elements 7, for example hexagon socket screws. The use of other or comparable fastening elements and/or shaft-hub connections are known to a person skilled in the art. Lastly, it is also clear from the illustration that the corrugated shape 14 of the insulating bodies 1 advantageously influence the air gaps and creepage distances in the interior 8 of the busbar 3 and the high-power contacts from the cable connection housing 4. An insulating shell which is not illustrated and is inserted into the insulating shell 6 illustrated additionally ensures that the air gaps and creepage distances are at least observed according to specifications. The nesting of the insulating shells is ideally configured in such a way that the specifications are exceeded at least slightly positively. It can furthermore be seen that the retaining shapes 13 of the insulating bodies 1 bear against the cable connection housing 4. For this purpose, the insulating bodies 1 pass through passage openings 9 arranged in the cable connection housing 4. It is clear in FIG. 4 that the passage openings 9 have fastening shapes 20. It is furthermore clear that the fastening shapes 20 are separated by cutouts 21. The cutouts 21 enable an insulating body 1 with its retaining shapes 13 to pass through each passage opening 9 and then, by rotating the insulating bodies 1, to arrange the latter positively on the fastening shapes 20 by means of their retaining shapes 13.

[0025] Even though different aspects or features of the invention are shown in the drawings in each case in combination, unless otherwise stated, it is clear to a person skilled in the art that the combinations illustrated and discussed are not the only ones possible. In particular, corresponding units or groups of features from different exemplary embodiments can be interchanged.

[0026] The articles “a” and “an” as used in this application should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
