Description

Die Erfindung betrifft ein Schneidklemmkontaktelement gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an insulation displacement contact element according to the preamble of claim 1.

Ein solches Schneidklemmkontaktelement ist aus der DE-OS 3526707 bekannt. Nachteilig bei diesem Schneidklemmkontaktelement ist, daß die Schneidklemmkontaktschenkel zu steif sind, so daß das Schneidklemmkontaktelement nicht für sehr dünne, z. B. nur 0,08 mm dicke Drähte, z. B. für sogenannte Lackdrähte verwendbar ist, die von den Schneiden im Kontaktierschlitz zwischen den der Kontaktschenkeln des bekannten Schneidklemmkontaktelementes durchtrennt werden. Außerdem ist es schwierig bei den bekannten Schneidklemmkontaktelementen, einen sehr schmalen Spalt mit definiertem Abstand zwischen den Schneiden für die dünnen Drähte herzustellen und zu gewährleisten.Such an insulation displacement contact element is known from DE-OS 3526707. A disadvantage of this insulation displacement contact element is that the insulation displacement contact legs are too stiff, so that the insulation displacement contact element is not suitable for very thin, e.g. B. only 0.08 mm thick wires, e.g. B. for so-called enamelled wires can be used, which are cut by the cutting in the contact slot between the contact legs of the known insulation displacement contact element. In addition, it is difficult with the known insulation displacement contact elements to produce and ensure a very narrow gap with a defined distance between the cutting edges for the thin wires.

Aufgabe der Erfindung ist, ein Schneidklemmkontaktelement definierter Spaltbreite mit einfachen Mitteln so auszubilden, daß damit auch ein Schneidklemmkontakt mit sehr dünnen Drähten hergestellt werden kann, ohne daß die Gefahr einer Durchtrennung der Drähte gegeben ist.The object of the invention is to design an insulation displacement contact element of a defined gap width with simple means such that an insulation displacement contact can also be produced with very thin wires without the risk of the wires being severed.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung werden in den Unteransprüchen gekennzeichnet. Anhand der Zeichnung wird die Erfindung im folgenden näher erläutert. Es zeigen:

This object is solved by the features of claim 1. Advantageous developments of the invention are characterized in the subclaims. The invention is explained in more detail below with the aid of the drawing. Show it:
  • Figure 1 is a side view of the insulation displacement contact element.
  • 2 shows a plan view of the insulation displacement contact element;

Das Schneidklemmkontaktelement 1 ist aus einem Blechstanzteil hergestellt und Bestandteil eines elektrischen Kontaktstücks, das neben dem Schneidklemmkontaktelement 1 mindestens ein weiteres Anschlußelement 4 für eine elektrische Kontaktierung aufweist. Die in den Fig. 1 bis 6 abgebildeten Kontaktstücke 5 verfügen über jeweils zwei gleich ausgebildete, parallel zueinander auf Abstand angeordnete Schneiklemmkontaktelemente 2, 3. Da das Anschlußelement 4 für die Funktion des erfindungsgemäßen Schneidklemmkontaktelementes unwesentlich ist, wird seine Raumform im Rahmen der Beschreibung der vorliegenden Erfindung nicht abgehandelt.The insulation displacement contact element 1 is made from a stamped sheet metal part and is part of an electrical contact piece which, in addition to the insulation displacement contact element 1, has at least one further connection element 4 for electrical contacting. The contact pieces 5 shown in FIGS. 1 to 6 each have two identical clamping contact elements 2, 3, which are arranged parallel and at a distance from one another. Since the connecting element 4 is insignificant for the function of the insulation displacement contact element according to the invention, its spatial shape becomes within the scope of the description of the present Invention not dealt with.

Ein Schneidklemmkontaktelement 1 ist aus einem ebenen flachen etwa rechteckigem Blechstück hergestellt und weist die Längskan­ten 6, 7 und die steckseitige Querkante 8 auf; an die der Querkante 8 gegenüberliegende Seite des Blechstückes, ist das Anschlußelement 4 einstückig angebunden.An insulation displacement contact element 1 is made from a flat, flat, rectangular piece of sheet metal and has the longitudinal edges 6, 7 and the transverse edge 8 on the plug side; to the cross edge 8 opposite side of the sheet metal piece, the connecting element 4 is integrally connected.

Von der Querkante 8 ist von der Quermitte 9 ausgehend, ein sich parallel zu den Längskanten 6, 7 erstreckender Trennschnitt in das Blechstück eingebracht, der im Bereich der Anbindung des Anschlußstückes 4 in einem kreisrunden Loch 10 ausläuft. Aus dem Trennschnitt resultieren zwei benachbarte Schneidklemmkontakt­schenkel 11, 12.Starting from the transverse edge 8, starting from the transverse center 9, a separating cut extending parallel to the longitudinal edges 6, 7 is made in the sheet metal piece, which in the region of the connection of the Connector 4 runs out in a circular hole 10. The adjacent cut results in two adjacent insulation displacement contact legs 11, 12.

Nach der Erfindung ist ein Stück in Richtung des Loches 10 im Abstand von der Querkante 8 vom Trennschnitt ausgehend, jeweils ein sich parallel zur Querkante 8 erstreckender Einschnitt 13 in die Schneidklemmkontaktschenkel 11, 12 eingebracht, so daß sich jeweils ein vom Einschnitt 13 bis zum Loch 10 erstreckendes Schneidklemmesser 14 ergibt. Die Länge der Einschnitte 13 und damit in etwa die Breite der Messer 14 beträgt vorzugsweise mindestens den Radius bzw. der halben Breite des Loches 10; sie ist jedoch vorzugsweise länger und kann z. B. bis zur Länge eines Durchmessers bzw. der Breite des Loches 10 betragen.According to the invention, a piece is made in the direction of the hole 10 at a distance from the transverse edge 8 from the separating cut, an incision 13 extending parallel to the transverse edge 8 is made in the insulation displacement contact legs 11, 12, so that one each from the incision 13 to the hole 10 extending insulation displacement knife 14 results. The length of the incisions 13 and thus approximately the width of the knives 14 is preferably at least the radius or half the width of the hole 10; however, it is preferably longer and can e.g. B. up to the length of a diameter or the width of the hole 10.

Die aus den Einschnitten 13 und dem Loch 10 resultierenden Schneidklemmesser 14 sind gleichsinnig aus der Blechebene abgebogen, vorzugsweise mit z. B. zwei Knickkanten 15, 16, so daß ein Kontaktspalt 19 definierter Abmessung zwischen den Messerkan­ten 18 der Schneidklemmesser 14 gebildet wird.The resulting from the incisions 13 and the hole 10 IDC 14 are bent in the same direction from the plane of the sheet, preferably with z. B. two folding edges 15, 16, so that a contact gap 19 of defined dimensions between the knife edges 18 of the insulation displacement knife 14 is formed.

Vorteilhaft ist von der Querkante 8, vorzugsweise bis zum jeweiligen Einschnitt 13 schräge Abschnitte vorzusehen, so daß jeweils eine Schrägkante 17 und damit aus den Schrägkanten 17 ein Einführtrichter 20 entsteht.It is advantageous to provide inclined sections from the transverse edge 8, preferably up to the respective incision 13, so that in each case an inclined edge 17 and thus an insertion funnel 20 arises from the inclined edges 17.

Aufgrund der Einschnitte 13 ist die Abbiegung der Schneidklemm­messer 14 aus der Blechebene einfach, so daß eine definierte Abmessung des Schneidklemmkontaktspaltes 19 gewährleistet werden kann. Des weiteren ist durch mehrere Knickkanten 15, 16 eine von der Anzahl der Knickkanten abhängige, weiche Federkraft der Schneidklemmesser 14 gewährleistbar, so daß die Schneidkanten der Messer den Draht nicht durchtrennen können. Insofern ist es mit einfachen Mitteln gelungen, ein Schneidklemmkontaktelement für dünne Drähte, insbesondere für sogenannte Lackdrähte zu schaffen.Due to the incisions 13, the bending of the insulation displacement knife 14 from the sheet metal plane is simple, so that a defined dimension of the insulation displacement contact gap 19 can be ensured. Furthermore, a plurality of fold edges 15, 16 ensures a soft spring force of the insulation displacement knife 14, which is dependent on the number of fold edges, so that the cutting edges of the knife cannot cut the wire. In this respect, simple means have succeeded in creating an insulation displacement contact element for thin wires, in particular for so-called enamelled wires.

Die Erfindung ermöglicht es, an einem Kontaktstück 5 zwei parallele freistehende Schneidklemmkontaktelemente 2, 3 anzuord­nen (Fig. 1 bis 3); die Erfindung ermöglicht sogar eine Wandung 21 zwischen zwei gegenüberliegenden Schneidklemmkontaktschenkeln 2 bzw. 3 vorzusehen, so daß ein in Querschnitt U-förmiger Schneidklemmbereich hoher Eigenstabilität entsteht, ohne daß die Federkräfte der Schneidklemmesser 14 dadurch beeinträchtigt werden.The invention makes it possible to arrange two parallel free-standing insulation displacement contact elements 2, 3 on a contact piece 5 (FIGS. 1 to 3); the invention even enables a wall 21 to be provided between two opposing insulation displacement contact limbs 2 and 3, so that an insulation displacement region of U-shaped cross section is of high intrinsic stability without the spring forces of the insulation displacement blade 14 being impaired thereby.
