So können beispielsweise die Anschlußteile 3, 3' auch auf andere Weise am Gehäuse 1 befestigt werden, Zum Beispiel können die Anschlußteile 3, 3' mit dem Gehäuse 1 verschraubt oder verklebt werden. Die Gestalt der als Einsatz ausgebildeten Anschlußteile 3, 3' kann beliebig variiert werden, sofern die Aufnahme im Gehäuse 1 entsprechend angepaßt wird. So ist es z.B. auch möglich, das Anschlußteil mit nur zwei Durchführungen für ein zweiadriges und ein dreiadriges Anschlußkabel auszustatten.The invention is not limited to the two exemplary embodiments explained in more detail. For example, the connecting parts 3, 3 'can also be attached to the housing in other ways 1 can be attached, for example, the connecting parts 3, 3 'with the Housing 1 can be screwed or glued. The shape of the trained as an insert Connection parts 3, 3 'can be varied as long as the inclusion in the housing 1 is adjusted accordingly.
