(1) An exemplary embodiment of the invention is shown in the drawings and is explained in more detail below. In the drawings:

(2) FIG. 1 shows a perspective view of a high-power plug connector system;

(3) FIG. 2 shows a perspective view of a high-power plug connector in a sectional view; and

(4) FIG. 3 shows a perspective exploded view of a high-power plug connector.

(5) The figures may contain partially simplified, schematic representations. In part, identical reference signs are used for like but possibly non-identical elements. Different views of like elements could be scaled differently. Directional indications such as left, right, top, and bottom are to be understood with reference to the figure in question and may vary in the individual representations with respect to the object shown.

DETAILED DESCRIPTION

(6) FIG. 1 shows a cable connection housing 1 of a high-power plug connector in a perspective view looking at the housing underside G.sub.U. The cable connection housing 1 consists here of two mutually engaging housing parts 2 and 2. An insulating body 3 is arranged in the cable connection housing 1 and receives a high-power contact 4, wherein two contact regions 4.1 and 4.3 can be seen in FIG. 1. The insulating body 3 and the contact regions 4.1 and 4.3 project into a connection region 6 for high-power plug connectors (not shown). The connection region 6 has at least one, advantageously at least two recesses 8, which are embodied as blind holes with threads. This allows corresponding high-power plug connectors to be detachably connected to the cable connection housing 1 by using threaded pins, screws or similar fastening elements. For fastening the cable connection housing 1, there are extensions 7 on the side of the cable connection housing 1 facing the housing top side Go. These extensions 7 are each embodied with at least one recess 8, wherein the recesses 8 are embodied as through-openings or through-holes. With the aid of these extensions 7, the cable connection housing 1 can be fastened to a carrier component, for example the floor of a vehicle, in particular a rail-bound vehicle. Screws, threaded pins, bolts or comparable fastening elements can be used for this purpose.

(7) A view of the interior of the cable connection housing 1 for a high-power plug connector system is disclosed in FIG. 2. It is clear here that the exemplary embodiment shown has two connection regions 6 on the housing part 2 of the cable connection housing 1. Furthermore, it can be seen that the housing part 2 of the cable connection housing 1 in the exemplary embodiment has a further connection region 6. Thus, a Y-distributor is formed. The housing parts 2 and 2 engage with one another in such a way that a nesting of the housing parts 2 and 2 is created, whereby, among other things, an improved sealing of the cable connection housing 1 against foreign media can be achieved. The use of additional sealing elements, for example in the form of rubber seals, further improves this sealing effect. The term foreign media means in particular fluids such as water and oil, but also dust and similar contaminants. It can be seen that the housing part 2 is detachably fixed to the housing part 2 by fastening elements 9. In the case shown, the fastening element 9 is a hexagon socket screw. Other fastening elements, in particular alternative embodiments of screws, are known to a person skilled in the art. In addition, FIG. 2 clearly shows that both housing part 2 and housing part 2 have at least one extension 7 with associated recess 8. It makes sense that the housing part 2 in particular has two extensions 7, wherein one extension 7 is concealed by the housing part 2 in the illustration. The non-visible extension 7 is thus located mirror-symmetrically to the extension 7 on the housing part 2. The insulating body 3 is formed around the one-piece high-power contact 4. In this case, the insulating body 3 exposes the high-power contact 4 only at the contact regions 4.1 and 4.3, as well as in parts at the contact region 4.2. In the illustrated exemplary embodiment, the contact regions 4.1 and 4.3 differ from the contact region 4.2. An alternative embodiment provides for the contact regions 4.1, 4.2 and 4.3 to be identical, which can considerably simplify the fitting or the assembly. In the exemplary embodiment shown, the different design of the contact regions 4.1 and 4.3 compared to the contact region 4.2 means that protection against incorrect plugging is provided. This means that high-power plug connectors intended for plugging with contact region 4.2 do not fit on the contact regions 4.1 and 4.3, and vice versa.

(8) The simple assembly of the illustrated embodiment of the cable connection housing 1 can be seen in FIG. 3. Starting from the right side of FIG. 3, the first housing part 2 is equipped with fastening elements 9. An insulating body 3 shown in the middle with a high-power contact 4 located therein is inserted into the housing part 2. For this purpose, the housing part 2 has a housing aperture, comparable to the shown housing apertures 5 of the housing part 2. The housing part 2 is then guided to the housing part 2 via the insulating body 3. In the process, the insulating body 3 is guided through the housing apertures 5. The Y-distributor design also prevents twisting of the high-power contact 4 or of the insulating body 3 receiving the high-power contact. The housing part 2 has recesses 8 corresponding to the fastening elements 9 of the housing part 2. The fastening elements 9 are now inserted into the recesses 8 of the housing part 2, in the shown exemplary embodiment as a blind hole with internal thread, and fastened or screwed there.

(9) Even though various aspects or features of the invention are shown in each case combination in the figures, it is apparent to a person skilled in the artunless otherwise indicatedthat the combinations shown and discussed are not the only possible ones. In particular, corresponding units or feature complexes from different exemplary embodiments may be interchanged with each other. In other words, aspects of the various embodiments described above can be combined to provide further embodiments.

(10) In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure
