DETAILED DESCRIPTION

[0020] The drawings contain partially 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.

[0021] 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.

[0022] FIG. 1 shows a perspective illustration of a high-power plug connection system with a horizontal section along a line parallel to the longitudinal axis of a cable connection housing 1. The embodiment illustrated has three high-power contacts 2. A high-power contact 2 is here positioned opposite two high-power contacts 2 of the same structure. Two high-power contacts 2 are illustrated without an insulating body 3. The insulating body 3 accommodates the corresponding high-power contact 2 within it. The high-power contacts 2 are connected to one another by means of an electrically conductive busbar 4. For this purpose, the high-power contacts 2 and the associated insulating bodies 3 have recesses 5. The busbar 5 has corresponding through openings 6. The securing elements 7 illustrated are guided through these through openings 6 and connected to the corresponding high-power contacts 2. In the design illustrated, the securing elements 7 are screws with a hexagonal screw head. The high-power contacts 2 have through openings 6, which are provided with an internal thread, for screwing the busbar 4 and the high-power contact 2. Instead of a thread in the through openings 6, a nut or comparable threaded socket can follow on the opposite side of the busbar 4. Alternatively, the high-power contacts 2 are each configured with a blind hole which is provided with an internal thread. Other connection options, in particular hub-and-shaft connections, are known to a person skilled in the art and can be used as an alternative to the securing elements 7 illustrated. In order to establish a secure and at least sufficient electrical connection, the high-power contacts 2 are aligned at least partially flush with that edge of the busbar 4 which is situated opposite the housing perforation 14 of the corresponding high-power contact 2. The cable connection housing 1 has a housing wall 9. This peripheral housing wall 9 forms an interior 10.

[0023] The insulating body 3 illustrated has a profiling 11, which is illustrated by way of example, at the from a busbar 4 to a housing wall 9 of the cable connection housing 1. The profiling 11 simply and advantageously increases the air gaps and creepage distances from the connection region of the busbar 4 and the high-power contact 2 illustrated therein. It can furthermore be seen that both the insulating body 3 and the high-power contact 2 situated therein each have a recess 5. This recess 5 can be formed, for example, by means of machining production processes. The insulating bodies 3 have a particularly clever design. They are provided with fastening elements 12 in addition to the profiling 11. The fastening elements 12 are integrally formed on the insulating body 3 as fundamentally plane, partly circular protrusions. The housing perforations 14, belonging to the insulating bodies 3, in the housing wall 9 of the cable connection housing 1 have recesses which correspond at least to the dimensions of the fastening elements 12 of the insulating bodies 3. The fastening elements 12 and the recesses are here positioned in the housing perforations 14 in such a way that the fastening elements 12 have a securing effect against axial displacement in the direction of the longitudinal axis L of the respective high-power contact 2 as soon as the high-power contact 2 with the associated insulating body 3 and with the busbar 4 is fixed detachably by the securing element 7. In other words, the fastening element 12 of the insulating body can be connected to the housing wall 9 in a comparable fashion to a bayonet catch.

[0024] The embodiment of a high-power plug connection system with a cable connection housing 1 is shown in FIG. 2 in an illustration in section comparable to the illustration in section of FIG. 1 but in a direct view from above. FIG. 1 and FIG. 2 show that the housing wall 9 has through openings for the connection of high-power plug connectors 15 to corresponding high-power contacts 2. However, if a cable connection housing 1 receives just two high-power contacts 2, a closure cap 2 can be inserted into the said through openings of the cable connection housing 1 in order both to secure the insulating body 3 of the corresponding high-power contact 2 and to protect the cable connection housing 1 against the ingress of, for example, water, oil, dust, or similar undesired foreign substances.

[0025] FIG. 3 shows the embodiment of the high-power plug connection system with the cable connection housing 1 in a vertical section along the longitudinal axis L of a high-power contact 2. The small physical dimensions of the interior 10 are particularly clear in this illustration. Furthermore, access for the purpose of mounting and maintaining the cable connection housing 1 via a housing cover 14 is clear. The housing cover 14 is here formed in such a way that a closure cap 16 can be connected to the housing cover 14 if the closure cap 16 is not required. Also clearly visible in this illustration in section is the connection of the busbar 4 to the high-power contacts 2. The high-power contacts 2 have a recess 5. The recesses 5 of the high-power contacts 2 lie in a horizontal plane E.sub.A. The busbar 4 can be applied to the recesses 5 in such a way that the busbar 4 ends flush with the respective high-power contacts 2 at their front side 8. As a result, the high-power contacts 2 project beyond the central plane E.sub.M of the busbar. By virtue of this embodiment, a small structural size of the cable connection housing 1 compared with the prior art is achieved.

[0026] A vertical cross-section of a high-power plug connection system, consisting of the cable connection housing 1 and components in the interior 10, is illustrated in FIG. 4. The arrangement of the high-power contacts 2 and the positioning of the recesses in the plane E.sub.A are particularly clear here. Because the section runs along the central plane E.sub.M of the busbar 4, the connections of the busbar 4 to the high-power contacts 2 by the securing elements 7 can be clearly seen. The securing elements 7 are here oriented along its longitudinal axis parallel to the central plane E.sub.M of the busbar 4, orthogonally to the plane E.sub.A. Simple access for maintenance can thus be effected after the housing cover 14 has been removed. Also clearly visible are the fastening elements 12 of the two insulating bodies 3 of the outer high-power contacts 2 which are configured as partly circular, integrally formed parts on the respective insulating body 3. After the busbar 4 has been detached and removed from the high-power contacts 2 by twisting the insulating body 3, these fastening elements 12 can be brought into alignment with coinciding recesses in the housing perforations 13. Then, as soon as the fastening elements 12 and the recesses in the housing perforations 13 coincide, the insulating bodies 3 with the high-power contacts 2 can be removed from the cable connection housing 1 and/or be inserted and/or be replaced.

[0027] 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 bundles of features from different exemplary embodiments can be interchanged.

[0028] 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.
