Abstract
Description
Die Erfindung bezieht sich auf einen Schneidklemmkontakt gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to an insulation displacement contact according to the features of the preamble of claim 1.
Bei solchen Schneidklemmkontakten kommt es darauf an, die vornehmlich aus Kupfer bestehende Metallseele der isolierten Einzelader sicher zu kontaktieren. Dem sich nach außen hin erweiternden Ader-Einführbereich am Klemmblatt kommt hierbei die Aufgabe zu, die Isolation der zu klemmenden Ader anzuschneiden. Im weiteren Fügeverlauf wird die Ader in den Klemmschlitz hineingedrückt, und hierbei wird die Aderisolation endgültig bis zur Metallseele hin durchtrennt. Bei diesem Vorgang muß die Aderisolation jeweils an den beiden einander diametral gegenüberliegenden Anschnittstellen in beiden Aderlängsrichtungen verdrängt werden, wofür die Konfiguration der Schneiden, insbesondere die Dicke der Schneiden maßgeblich ist. Hierbei besteht das Problem, im Hinblick auf gute Schneideigenschaften die an die Schneiden angrenzenden Bereiche des Klemmblattes möglichst dünn auszuführen. Bei harten Aderisolationen hat dies zur Folge, daß beim Klemmvorgang entweder die Schneiden beschädigt werden oder die Schneiden nicht die erforderliche Schneidkraft aufbringen. Zudem muß eine ausreichende Stromtragfestigkeit sichergestellt sein, weshalb der Schneidenwinkel nicht beliebig klein gemacht werden kann. Dies gilt besonders dann, wenn Schneidklemmkontakte der in Rede stehenden Art aus einem flachen Metallband ausgestanzt werden und eine Nachbehandlung der Schneiden nicht in Betracht kommt.at such insulation displacement contacts, it depends, the predominantly made of copper existing metal core of the isolated single core safe to contact. The outwardly expanding wire insertion area on the clamping sheet here comes the task, the isolation of to cut the strangling vein. In the further joining process, the vein is in pressed in the clamping slot, and in this case the core insulation finally becomes the metal core severed. In this process, the core insulation must each at the two diametrically opposed gates in both wire longitudinal directions repressed become, for what the configuration of the cutting edges, especially the thickness of the cutting edges decisively is. Here is the problem with regard to good cutting properties the as far as possible adjacent to the cutting areas of the clamping sheet run thin. at hard wire insulation, this has the consequence that during the clamping process either the blades are damaged or the cutting edges do not apply the required cutting force. In addition, one must sufficient current carrying capacity must be ensured, which is why the Cutting angle can not be made arbitrarily small. this applies especially if insulation displacement contacts of the person in question Art be punched out of a flat metal band and an aftertreatment the cutting does not come into consideration.
Zum einen hat man durch ein Verschränken der Schneiden zueinander versucht, die Kontakteigenschaften zu verbessern. Zum anderen hat man im Einführbereich angrenzend an die nach außen hin divergierenden Schneiden im spitzen Winkel zueinanderstehende Schneidenflanken vorgesehen, um den Anschnitt harter Aderisolationen zu verbessern.To the one has one by entangling the Cutting each other tries to improve the contact properties. On the other hand you have in the introduction area adjacent to the outside towards diverging cutting edges at an acute angle to each other Cutting edges provided to the gate of hard wire insulation to improve.
Der Erfindung liegt die Aufgabe zugrunde, einen Schneidklemmkontakt der eingangs genannten Art zu schaffen, der vor allem im Hinblick auf harte Aderisolationen eine optimierte Schneidengeometrie aufweist.Of the Invention is based on the object, an insulation displacement contact to create the type mentioned, especially with regard to on hard wire insulation has an optimized cutting geometry.
Diese Aufgabe wird bei einem Schneidklemmkontakt der genannten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.These Task is at a insulation displacement contact of the type mentioned by the characterizing features of claim 1 solved.
Für die erfindungsgemäße Lösung ist wesentlich, daß die Schneiden an in der Dicke abgesetzten Messerstegen ausgebildet sind, die in Relation zur Dicke des Klemmblattes dünnwandig ausgeführt sind, also eine Dicke haben, die wesentlich geringer als die des Klemmblattes ist. Die Messerstege haben im Hinblick auf eine ausreichende Stabilität nur eine geringe Höhe oder Breite, die in der Größenordnung der Dicke der Messerstege liegt. Diese Höhe oder Breite bestimmt den Abstand, den die sich verdickenden Bereiche des Klemmblattes, die an die Messerstege anschließen, von den Schneiden der Messerstege haben. Die sich verdickenden Klemmblattbereiche stabilisieren nicht nur die Messerstege, sie sorgen auch für die Verdrängung der Aderisolation, weil sie zu den Messerstegen hin abfallende Schrägflächen bilden, die als Keilflächen wirken.For the solution according to the invention essential that the Cutting edges are formed in thickness-cut knife bars, which are thin-walled in relation to the thickness of the clamping sheet, So have a thickness that is much lower than that of the clamping sheet is. The knife bars have only one in view of sufficient stability low altitude or width that is of the order of magnitude the thickness of the knife bars is. This height or width determines the Distance that the thickening areas of the clamping sheet, the connect to the knife bridges, from the cutting edges of the knife bars. The thickening clamping sheet areas not only stabilize the knife bars, they also provide for the displacement of the Core insulation because they form sloping sloping surfaces towards the knife edges, as wedge surfaces Act.
