Des Weiteren ist in der DE 197 18 004 C1 ein Kontaktsystem bestehend aus einem Buchsenteil und einem Steckerteil mit federelastischen Kontaktlamellen offenbart, zur Übertragung von hohen Strömen. Furthermore, DE 197 18 004 C1 discloses a contact system consisting of a socket part and a plug part with spring-elastic contact blades for transmitting high currents.
In der FR 618 171 A sind Vorrichtungen offenbart, die geeignet sind zum Klemmen von - elektrischen Leitern für elektrische Geräte, bei denen insbesondere ummantelte elektrische Leiter in isolierende Vorrichtungen zur Montage verklemmt werden. Ferner ist in der DE 102 20 108 B4 ein Kontaktelement zum Anschluss eines Litzenleiters offenbart, wobei das Kontaktelement aus einer Klemmhülse und einer in der Klemmhülse schraubbar gehaltenen, dornartigen Kontaktteil gebildet ist, wobei das Kontaktteil eine kegelförmige Spitze mit einem Winkel α zur Senkrechten aufweist und an der Klemmhülse ein trichterförmiges Anschlussende angesehen ist, in das der Litzenleiter in eine innere In FR 618 171 A devices are disclosed which are suitable for clamping - electrical conductors for electrical equipment, in which in particular sheathed electrical conductors are clamped in insulating devices for mounting. Furthermore, DE 102 20 108 B4 discloses a contact element for connecting a stranded conductor, the contact element being formed from a clamping sleeve and a mandrel-like contact part which is screwed in the clamping sleeve, the contact part having a conical tip at an angle α to the perpendicular and on the clamping sleeve a funnel-shaped connection end is considered, in which the stranded conductor in an inner
Anschlusskammer einführbar ist und wobei ferner eine Kegelfläche mit einem Winkel ß zur Senkrechten ausgebildet ist und das Kontaktteil jedoch nur soweit in die Anschlusskammer und den darin eingeführten Litzenleiter einschraubbar ist, dass zwischen der Spitze des Kontaktteils und der Kegelfläche der Schulter eine Mindestüberlappung verbleibt. Further, a conical surface is formed with an angle ß to the vertical and the contact part but only as far into the connection chamber and the inserted therein stranded conductor can be screwed that a minimum overlap remains between the tip of the contact part and the conical surface of the shoulder.
Diese technische Lehre offenbart ein Kontaktelement, bei dem das Litzenleiterende allerdings von der Klemmhülse gegen eine Seitenwand verpresst wird und die Gefahr besteht, dass die Enden der Litzenleiter beim Verpressen beschädigt werden oder gar durchtrennt werden. This technical teaching discloses a contact element in which the stranded conductor end is, however, pressed by the clamping sleeve against a side wall and there is a risk that the ends of the stranded conductors are damaged during pressing or even severed.
Insbesondere beim Verschrauben der Klemmhülse entstehen hohe Kräfte, die die Litzenleiter teilweise oder vollständig abscheren können, was im ungünstigen Fall allerdings unentdeckt bleibt. In particular, when screwing the clamping sleeve arise high forces that can shear off the stranded conductors partially or completely, but this remains undetected in the worst case.
