Abstract

The cutting contact (1), formed from flat material, has two contact limbs (2) between which a wire (7) can be pressed. The mutually facing inner sides (5) of the contact limbs (2) are bent out of the plane of the material about a longitudinal edge (6) extending parallel to their longitudinal edges and are thus turned towards one another. This produces a sharp contact edge which requires a reduced contact force for making a secure contact. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Schneidklemme zum An­schließen eines elektrischen Schaltdrahtes, wobei der Schalt­draht in einen zwischen zwei Klemmschenkel gebildeten Klemm­schlitz der aus Flachmaterial gebildeten Schneidklemme so ein­drückbar ist, daß dabei die Isolation des Schaltdrahtes ein­geschnitten wird und Innenseiten der Klemmschenkel federnd am metallischen Kern den Schaltdrahtes anliegen.The invention relates to an insulation displacement terminal for connecting an electrical jumper wire, the jumper wire being able to be pressed into a clamping slot formed between two clamping legs of the insulation piercing formed from flat material in such a way that the insulation of the jumper wire is cut and the inside of the clamping legs resiliently on the metallic core of the jumper wire issue.

Eine derartige Schneidklemme ist z. B. durch die DE-PS 20 07 487 bekannt geworden. Die Innenseiten der Klemmschenkel sind hier­bei parallel aufeinander ausgerichtet, so daß es zu einer li­nienförmigen Anlage am Schaldrahtkern kommt. Die Klemmschen­kel werden in der Materialebene ausgelenkt. In dieser Richtung ist jedoch ihre Elastizität begrenzt, so daß Schaltdräht un­terschiedlichen Durchmessers nur in einer begrenzten Bandbreite angeschlossen werden können.Such an insulation displacement clamp is, for. B. become known from DE-PS 20 07 487. The inner sides of the clamping legs are aligned parallel to each other, so that there is a linear contact with the core wire. The clamping legs are deflected in the material plane. In this direction, however, their elasticity is limited, so that jumper wires of different diameters can only be connected in a limited bandwidth.

Nach der DE-OS 33 11 447 ist einer der beiden Klemmschenkel an seinem Fußende um eine quer zur Längsrichtung in der Material­ebene liegende Biegekante gegenüber dem anderen Klemmschenkel um annähernd Materialstärke ausgelenkt. Die beiden Klemmschen­kel sind im Klemmbereich durch einen Schervorgang voneinander getrennt. Eine solche Anordnung ermöglicht es, daß die beiden Klemmschenkel beim Eindrücken des Schaltdrahtes auch senkrecht zur Materialstärke soweit auseinandergespreizt werden, daß Schaltdrähte von erheblich unterschiedlichem Durchmesser ange­klemmt werden können. Um die volle Klemmkraft aufbringen zu können, müssen jedoch die Klemmschenkel z. B. in einem Gehäuse einer Anschlußleiste abgestützt werden, was unter Umständen mit konstruktiven Mehraufwand und Einschränkung der konstruktiven Gestaltungsmöglichkeiten verbunden ist.According to DE-OS 33 11 447 one of the two clamping legs is deflected at its foot end by a bending edge lying transversely to the longitudinal direction in the material plane with respect to the other clamping leg by approximately material thickness. The two clamping legs are separated from one another in the clamping area by a shearing process. Such an arrangement enables the two clamping legs to be spread apart so far perpendicularly to the material thickness when the jumper wire is pressed in that jumper wires of considerably different diameters can be clamped on. In order to be able to apply the full clamping force, the clamping limbs, for. B. are supported in a housing of a terminal block, which may be with constructive additional effort and limitation of the constructive design options.

Der Erfindung liegt die Aufgabe zugrunde, die in einfacher Wei­se das Anschließen von Schaltdrähten von sehr unterschiedlichem Durchmesser bei hoher Kontaktsicherheit zu ermöglichen.The invention has for its object to enable the connection of jumper wires of very different diameters in a simple manner with high contact reliability.

Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Zumindest eine Innenseite der Klemmschenkel liegt nun nicht mehr flach sondern kantenförmig an dem Schaltdrahtkern an. Die­se wird auch bei geringer Federkraft geringfügig eingekerbt und sicher kontaktiert. Aufgrund der geringeren Federkraft können die Federschenkel elastischer ausgebildet werden. Bei genügend starker Auslenkung der Innenseiten aus der Materialebene kann der entsprechende Klemmschenkel beim Eindrücken des Schaltdrahtes in sich um seine Längsachse verdreht werden, wodurch die Klemm­weite ebenfalls erheblich variiert werden kann, ohne daß sich die Klemmkraft erheblich verändert.This object is achieved by the invention according to claim 1. At least one inside of the clamping leg is no longer flat but edge-shaped on the jumper wire core. This is notched slightly even with low spring force and contacted securely. Due to the lower spring force, the spring legs can be made more elastic. If the inner sides are deflected sufficiently out of the plane of the material, the corresponding clamping leg can be rotated about its longitudinal axis when the jumper wire is pressed in, so that the clamping width can also be varied considerably without the clamping force changing significantly.

Wenn die Klemmschenkel im Klemmbereich genügend breit sind, ist es zweckmäßig, sie innerhalb des Klemmbereiches in sich zu ver­biegen, um eine hinreichende Verdrehung und Spitzenwirkung zu erzielen. Sind die Klemmschenkel jedoch im Verhältnis zu ihrer Dicke sehr schmal, so lassen sie sich nur schwer verbiegen. Sie können dann zwischen dem Fußende und dem Klemmbereich bleibend tordiert werden, so daß sich die gewünschte Spitzenwirkung ebenfalls einstellt.If the clamping legs are sufficiently wide in the clamping area, it is expedient to bend them within the clamping area in order to achieve a sufficient twist and tip effect. However, if the clamping legs are very narrow in relation to their thickness, they are difficult to bend. They can then be permanently twisted between the foot end and the clamping area, so that the desired tip effect is also achieved.

Vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 6 gekennzeichnet:Advantageous developments of the invention are characterized in claims 2 to 6:

Die Weiterbildung nach Anspruch 2 läßt sich technologisch noch relativ leicht verwirklichen und ermöglicht eine hinreichend starke Verdrehung der Innenseiten der Klemmschenkel mit der ge­wünschten Spitzenwirkung an der Kontaktstelle.The development according to claim 2 is technologically still relatively easy to implement and allows a sufficiently strong rotation of the inside of the clamping leg with the desired point effect at the contact point.

Die Weiterbildung nach den Ansprüchen 3 und 4 führen dazu, daß die Kontaktstellen am Schaltdraht zueinander versetzt sind. Da­durch verteilt sich die Kerbwirkung auf unterschiedliche Be­reiche und verringert sich die Gefahr des Drahtbruchs. Der Längsversatz am Schaltdraht begünstigt das Auslenken der Kon­taktkanten durch Torsion der Klemmschenkel.The development according to claims 3 and 4 lead to the contact points on the jumper wire being offset from one another. This distributes the notch effect to different areas and reduces the risk of wire breaks. The longitudinal offset on the jumper wire favors the deflection of the contact edges by torsion of the clamping legs.

Die Weiterbildung nach Anspruch 5 behindert das Verbiegen des Schaltdrahtes zwischen den zueinander versetzten Klemmschenkeln.The development according to claim 5 hinders the bending of the jumper wire between the offset limbs.

Durch die Weiterbildung nach Anspruch 6 können an eine Schneid­klemme zwei Schaltdrähte angeschlossen werden was insbesondere für Verteiler in Telekommunikationsanlagen von Vorteil ist, bei denen Veränderungen in der Drahtführung unterbrechungsfrei vor­genommen werden können.Through the development according to claim 6, two jumper wires can be connected to an insulation displacement terminal, which is particularly advantageous for distributors in telecommunication systems in which changes in the wire routing can be made without interruption.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert:

  • Die Figuren 1 bis 3 zeigen in zwei Seitenansichten und einer Draufsicht eine Schneidklemme zum Anschließen eines Schaltdrah­tes,
  • Fig. 4 die Klemme nach Fig. 3 mit einem Schaltdraht und einem Teil eines Klemmengehäuses,
  • Fig. 5 eine Draufsicht auf eine andere Schneidklemme,
  • Fig. 6 und 7 eine Seitenansicht und eine Draufsicht auf eine andere Schneidklemme zum Anschließen zweier Schalt­drähte,
  • Fig. 8 die Klemme nach Figur 7 mit einem Schaltdraht.
The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the drawing:
  • FIGS. 1 to 3 show, in two side views and a top view, an insulation displacement terminal for connecting a jumper wire,
  • 4 shows the clamp according to FIG. 3 with a jumper wire and part of a clamp housing,
  • 5 is a plan view of another insulation displacement clamp,
  • 6 and 7 are a side view and a plan view of another insulation displacement terminal for connecting two jumper wires,
  • Fig. 8 shows the terminal of Figure 7 with a jumper wire.

Nach den Figuren 1 bis 3 weist eine aus Flachmaterial herge­stellte Schneidklemme 1 zwei längliche Klemmschenkel 2 auf, die durch einen mittleren, sich in der Längsrichtung der Schneid­klemme 1 erstreckenden Schnitt 3 voneinander getrennt sind. Dieser ist im Anschluß an das freie Stirnende der Klemmschen­ kel 2 zu einem Klemmschlitz 4 verengt, in den der anzuschließen­de Schaltdraht eingedrückt werden kann. Im Bereich des Klemm­schlitzes sind die einander zugewandten Innenseiten 5 der Klemmschenkel 2 um eine zum Klemmschlitz 4 parallele Längskante 6 aus der Materialebene herausgebogen, so daß die Innenseiten um ungefähr 45° zur Materialebene verdreht sind.According to FIGS. 1 to 3, a cutting clamp 1 made of flat material has two elongated clamping legs 2, which are separated from one another by a central cut 3, which extends in the longitudinal direction of the cutting clamp 1. This is connected to the free end of the clamp kel 2 narrowed to a clamping slot 4 into which the jumper wire to be connected can be pressed. In the area of the clamping slot, the mutually facing inner sides 5 of the clamping legs 2 are bent out of the material plane by a longitudinal edge 6 parallel to the clamping slot 4, so that the inner sides are rotated by approximately 45 ° to the material plane.

Die beiden Klemmschenkel 2 sind an ihrem Fußende um eine sich in der Materialebene quer zum Klemmschlitz erstreckende Querkan­te gegeneinander um etwa die Materialdicke verbogen.The two clamping legs 2 are bent at their foot ends by a transverse edge extending in the material plane transversely to the clamping slot by approximately the material thickness.

Nach Figur 4 ist in den Klemmschlitz 4 (Figur 3) vom freien Stirnende her ein isolierter elektrischer Schaltdraht 7 zwi­schen die Klemmschenkel 2 eingedrückt. Dabei ist die Schalt­drahtisolation eingeschnitten worden. An diesen Stellen drücken sich die einander zugewandten Kanten der Innenseiten in den Schaltdrahtkern kontaktgebend ein. Am Schaltdraht 7 entstehen entsprechend der Auslenkung der Klemmschenkel 2 zueiander ver­setzte Einkerbungen. Gleichzeitig sind die beiden Klemmschenkel 2 soweit auseinander gedrückt worden, daß sich die Weite des Klemmschlitzes der Schaltdrahtdicke angepaßt hat.According to FIG. 4, an insulated electrical switching wire 7 is pressed into the clamping slot 4 (FIG. 3) between the clamping legs 2 from the free end. The jumper wire insulation has been cut. At these points, the mutually facing edges of the inner sides press into the contact wire core in a contact-making manner. On the jumper wire 7, corresponding to the deflection of the clamping legs 2, notches are offset. At the same time, the two clamping legs 2 have been pressed apart so far that the width of the clamping slot has adapted to the jumper wire thickness.

Die Schneidklemme 1 ist in ein Gehäuseteil 12 eingesetzt, das zu beiden Seiten der Schneidklemme 1 mit zwei senkrecht zu dieser stehenden Halteschlitzen 11 für den Schaltdraht 7 ver­sehen ist. Dieser wird dadurch beim Eindrücken zwischen die Klemmschenkel 2 kaum verbogen.The insulation displacement connector 1 is inserted into a housing part 12 which is provided on both sides of the insulation displacement connector 1 with two holding slots 11 for the jumper wire 7 which are perpendicular to the latter. This is hardly bent when pressed between the clamping legs 2.

Nach Figur 5 liegen die Klemmschenkel 8 einer ähnlichen Schneid­klemme im wesentlichen in der Materialebene. Lediglich die Innenseiten sind entlang der Längskante 6 in entgegengesetzter Richtung ausgebogen, so daß die einander zugewandten Innenkan­ten am Schaltdraht zueinander versetzt angreifen können.According to Figure 5, the clamping legs 8 of a similar insulation piercing are essentially in the material plane. Only the inner sides are bent out in the opposite direction along the longitudinal edge 6, so that the mutually facing inner edges can engage on the jumper wire offset from one another.

Nach den Figuren 6 und 7 weist eine andere Schneidklemme 9 zwei KLemmschlitze auf, die zwischen drei Klemmschenkeln 10 gebildet sind. Die äußeren KLemmschenkel sind dabei in sich verdreht, der mittlere Klemmschenkel ist im Klemmbereich bogenförmig um die Mittelachse der Schneidklemme 9 gebogen. Außerdem ist er an seinem Fußende aus der Materialebene herausgebogen und zu den äußeren Klemmschenkeln versetzt.According to FIGS. 6 and 7, another insulation displacement clamp 9 has two Clamping slots that are formed between three clamping legs 10. The outer clamping legs are twisted in themselves, the middle clamping leg is curved in the clamping area around the central axis of the insulation piercing 9. In addition, it is bent out of the material plane at its foot end and offset to the outer clamping legs.

Nach Figur 8 ist ein Schaltdraht 7 ähnlich wie nach Figur 4 zwischen den mittleren und einen der äußeren Klemmschenkel 10 eingedrückt und zwischen deren einander augewandten Innenkanten kontaktgebend eingeklemmt. Davon unabhängig kann in gleicher weise in den anderen Klemmschlitz ein zusätzlicher Schaltdraht eingedrückt werden.According to FIG. 8, a switching wire 7 is pressed in like in FIG. 4 between the middle and one of the outer clamping legs 10 and is clamped in contact-making manner between the inner edges thereof facing each other. Irrespective of this, an additional jumper wire can be pressed into the other clamping slot in the same way.
