Description

Die Erfindung bezieht sich auf ein Kontaktstück mit einem Grundkörper, welcher eine Ausnehmung zur Aufnahme eines Leiters aufweist und weiterhin auf eine Anschlussklemme mit einem Kontaktstück und auf ein Verfahren zum Kontaktieren eines Leiters mit einem Kontaktstück.The invention relates to a contact piece with a Basic body, which has a recess for receiving a conductor and continues to a terminal with a Contact piece and a method for contacting a Ladder with a contact piece.

Ein Kontaktstück der vorab genannten Gattung dient im allgemeinen zum Anschluss eines elektrischen Leiters. Dies erfolgt durch eine Kontaktierung einer Leiterseele und ggf. durch ein der Kontaktierung vorausgegangenes Durchdringen einer Leiterisolierung. Die Kontaktierung kann auch in Verbindung mit weiteren Kontakt- oder Klemmmitteln erfolgen. Das Einsatzgebiet erstreckt sich von der Installations- bishin zur Fernmeldetechnik.A contact piece of the aforementioned type is generally used for connecting an electrical conductor. this happens by contacting a conductor core and possibly by a the contacting previous penetration of a conductor insulation. The contacting can also be used in conjunction with take further contact or clamping means. The application area extends from the installation manual to the telecommunication technology.

Übliche Kontakt- oder Klemmmitteln wie beispielsweise eine Anschluss-, eine Schneidklemme oder auch ein Schneidklemm-Kontakt werden gleichermaßen für den Anschluss von elektrischen Leitern verwendet. Im Hinblick auf die Wirtschaftlichkeit der Herstellung von Kontakt- oder Klemmmitteln ist es wünschenswert so wenig und so einfache Bauteile wie möglich einzusetzen. Andererseits ist es jedoch erforderlich eine hinreichende und sichere Kontaktierung des elektrischen Leiters durch ein Kontakt- oder Klemmmittel herbeizuführen.Usual contact or clamping means such as a Terminal, a cutting terminal or a insulation displacement contact be equally for the connection of electrical Ladders used. In terms of economy It is the manufacture of contact or clamping means Desirable as few and as simple components as possible use. On the other hand, it is necessary a adequate and safe contacting of the electrical conductor by a contact or clamping means bring about.

Aus der DE 26 43 471 C3 geht hervor, dass eine Anschlussklemme aus einem Klemmkörper aus bandförmigem Material besteht. Der Klemmkörper bildet hierbei eine Auflage für einen anzuschließende Leiter. Weiterhin weist der Klemmkörper eine Klemmschraube auf, die in einem Gewinde im Klemmkörper geführt ist. From DE 26 43 471 C3 shows that a terminal consists of a clamp body of band-shaped material. The clamp body forms a support for a to be connected Ladder. Furthermore, the clamping body has a Clamping screw, which is guided in a thread in the clamping body is.

Der Klemmkörper führt dabei die Klemmschraube mittig im Bandmaterial. Seitliche Schenkel sind unter die Führung der Klemmschraube bis zu annähernder Berührung an ihrem Ende zurückgekröpft und weisen in ihren Flanken Ausnehmungen auf, die einen Steg als Auflage stehen lassen. Diese Anschlussklemme kann nach konstruktiven Gesichtspunkten in die Kategorie der Buchsen- oder auch Bügelklemmen eingeordnet werden.The clamp body guides the clamping screw in the center of the strip material. Lateral thighs are under the leadership of Retaining screw bent back to approximate contact at its end and have recesses in their flanks, which leave a bridge as a support. This terminal can be considered constructive in the category the socket or ironing clamps are arranged.

Eine so genannte Schneidklemme für die Kontaktierung eines mit einer Isolierung ummantelten elektrischen Leiterdrahts ist in der DE 86 04 746 U offenbart. Die Schneidklemme besteht aus zwei, in einem vorgegebenen gegenseitigen Abstand parallel zueinander ausgerichteten Schneidplatten mit einem senkrechten, nach oben zu offenen und am offenen Ende trichterförmig aufgeweiteten Schlitz zum Eindrücken des Leiterdrahtes. Hierbei weisen die Schneidplatten an ihrem der Schlitzöffnung entgegengesetzten Ende eine gemeinsame Bodenplatte auf, die auf einer Seite in ein Verbindungselement, beispielsweise einen Federkontakt, übergeht. Der mit einer Isolierung ummantelte elektrische Leiterdraht wird so am offenen Ende in den trichterförmig aufgeweiteten Schlitz eingedrückt, dass die Isolierung durch die parallel zueinander ausgerichteten Schneidplatten aufgetrennt wird. Dadurch kommen die Schneidplatten mit dem Leiterdraht in Berührung und es entsteht ein elektrisch leitender Kontakt.A so-called cutting clamp for contacting a with insulation sheathed electrical conductor wire is disclosed in DE 86 04 746 U. The cutting clamp is made from two, at a given mutual distance parallel aligned cutting inserts with a vertical, open at the top and funnel-shaped at the open end expanded slot for pressing the conductor wire. Here, the inserts have on their the Slot opening opposite end a common bottom plate on, on one side in a connecting element, For example, a spring contact, passes. The one with Insulation sheathed electrical conductor wire is so open End pressed into the funnel-shaped widened slot, that isolation through the parallel to each other aligned cutting plates is separated. This will come the cutting plates in contact with the conductor wire and It creates an electrically conductive contact.

Aus der FR 2 304 193 ist ferner ein Kabelverbinder bekannt, der zwei mit Schneidkanten versehene Fortsätze und eine Schraube aufweist, wobei die Schneidkanten beim Anziehen der Schraube die Kunststoffisolierung eines elektrischen Kabels durchdringen und dieses mechanisch und elektrisch kontaktieren.From FR 2 304 193 a cable connector is also known, the two provided with cutting edges extensions and a Has screw, wherein the cutting edges when tightening the Screw the plastic insulation of an electric cable penetrate and contact this mechanically and electrically.

Wie für die Klemmkörper der Anschlussklemmen gilt auch für die gängigen Varianten der Schneidklemmen, dass komplexe Formen zu einer Erhöhung der Herstellungskosten führen können. Bei gängigen Schneidklemmen fallen zudem beim Klemmvorgang entstehende Klemmkräfte sowie Kontaktflächen zwischen Leiterseele und Kontaktstück unter Umständen relativ gering aus.As for the clamp body of the terminals also applies to the common variants of insulation displacement connectors that complex shapes can lead to an increase in production costs. With common insulation displacement terminals also fall during the clamping process resulting clamping forces and contact surfaces between the conductor core and contact piece may be relatively low.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Kontaktstück anzugeben, welches zum einen einfach und damit kostengünstig herzustellen ist und zum anderen eine ausreichende Kontaktierung zwischen einer Leiterseele und dem Kontaktstück gewährleistet. Weiterhin soll eine zugehörige Anschlussklemme mit dem Kontaktstück und ein Verfahren zum Kontaktieren eines Leiters mit dem Kontaktstück angegeben werden.It is therefore the object of the present invention, a contact piece specify, which for a simple and therefore cost is to produce and on the other a sufficient Contacting between a conductor core and the contact piece guaranteed. Furthermore, an associated terminal with the contact piece and a method for contacting a Ladder can be specified with the contact piece.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of the claim 1 solved.

Das Kontaktstück lässt sich auf der Basis einfacher und dadurch monetär günstiger Fertigungsschritte herstellen bzw. umsetzen. Gleichermaßen einfach und günstig fallen demnach die Fertigungswerkzeuge aus, da beispielsweise keine Schneidenbildung wie bei einer Schneidklemme nötig ist.The contact piece can be based on simpler and thereby produce monetarily favorable production steps or implement. Equally simple and cheap fall accordingly the production tools from, for example, no cutting edge as is necessary with a cutting clamp.

Für die Anwendung und den Einsatz in der Praxis bietet dieses Kontaktstück eine schnelle, komfortable und dennoch sichere Anschlussmöglichkeit eines Leiters, da insbesondere ein aufwendiges Abisolieren des Leiters gänzlich entfällt.For the application and the application in practice this offers Contact piece a fast, comfortable and yet secure Connection possibility of a conductor, as in particular a complex Stripping the conductor completely eliminated.

Die auf Grund der neuartigen Kontaktierung erzielte große Kontaktfläche zwischen dem Kontaktstück und der zu klemmenden Leiterseele dient nicht zuletzt durch einen genügend großen und gleichbleibenden Kontaktdruck einer hinreichenden Kontaktierung. Dadurch wird der Übergangswiderstand gering gehalten, was eine unzulässige Erwärmung der Anschlussstelle und ferner einen nachteiligen Spannungsabfall verhindert. Eine derartige Kontaktierung wird auch als kalte Kontaktierung bezeichnet, wobei eine stoffschlüssige Verbindung mittels Lot oder dergleichen nicht notwendig ist.The achieved due to the novel contact large Contact surface between the contact piece and to be clamped Ladder soul serves not least by a sufficiently large and constant contact pressure of a sufficient contact. As a result, the contact resistance is kept low, what an inadmissible warming of the junction and Furthermore, prevents an adverse voltage drop. A Such contacting is also referred to as cold contacting, wherein a material connection by means of solder or the like is not necessary.

In bevorzugter Ausgestaltung ist die Ausnehmung am Kontaktstück als Langloch und bei einer weiteren Ausführungsform der Erfindung als Nut ausgebildet. Dabei kann die Ausnehmung des Kontaktstücks derart bemessen sein, dass der Leiter teilweise oder vollständig aufgenommen ist. Weiterhin ist die Ausnehmung des Kontaktstücks geschlossen oder geöffnet ausgebildet.In a preferred embodiment, the recess is on the contact piece as a slot and in a further embodiment of the Invention designed as a groove.

Hierbei kann das Kontaktstück für unterschiedliche Rahmenbedingungen und Anforderungen hinsichtlich der Einbaugröße und -lage, Kontakt- und Leiterwerkstoff, ausgelegt werden und stellt somit ein äußerst gestaltungs- und anpassungsfähiges Kontaktmittel dar. Weiterhin entsteht durch diese Art der Verbindung eine flächige und gaseinschlussfreie Kontaktierung, die nur eine geringe Kerbspannung im Leiter bewirkt, da ohne ein in die Leiterisolierung radial einschneidendes Werkzeug die Leiterseele geklemmt wird.Here, the contact piece for different conditions and requirements regarding the installation size and -Layer, contact and conductor material, to be designed and thus represents a very creative and adaptable Contact means dar. Furthermore, created by this type of Connection a surface and gas-free contact, which only causes a slight notch stress in the conductor because without a radially incising tool in the conductor insulation the conductor core is clamped.

Dies dient insbesondere zur Erhöhung der Steifigkeit des Kontaktstücks, wodurch sowohl große Leiterquerschnitte als auch harte Leitermaterialien eingesetzt und zudem hohe Klemmkräfte wirksam werden können.Advantageously, the base body has at least one fold. This serves in particular to increase the rigidity of the contact piece, whereby both large conductor cross sections as well hard conductor materials used and also high clamping forces can be effective.

Die Aufgabe wird bezüglich der Anschlussklemme erfindungsgemäß durch die Merkmale des Anspruchs 9 gelöst.The object is according to the invention with respect to the terminal solved by the features of claim 9.

Die Längskante 4 dient als Scher-, Schneid-, Abisolier-, Verdrängungs- oder auch Unterbrechungskante.The recess 3 is parallel to the two longitudinal edges of the Body 2 aligned. It can have one at both ends Radius have. On both sides are in the longitudinal direction of the recess 3 legs 5 are formed, which correspond to the recess 3 form-related contours, of which at least a contour has a longitudinal edge 4. The longitudinal edge 4 serves as shear, cutting, stripping, displacement or also interruption edge.

Der aufzunehmende erste Leiter L1 ist achsparallel und in der Längsrichtung der Ausnehmung 3 teilweise, vollständig oder überlappend auf der Aussparung 3 platzierbar. Die Ausnehmung 3 ist dabei zur zumindest teilweisen Längsaufnahme des ersten aufzunehmenden Leiters L1 ausgebildet. Die Ausnehmung 3 ist zudem derart bemessen, dass der Leiter L1 teilweise oder vollständig in seinem Durchmesser aufgenommen werden kann.The male first conductor L1 is parallel to the axis and in the The longitudinal direction of the recess 3 partially, completely or overlapping on the recess 3 placeable. The recess 3 is for at least partial longitudinal recording of the first formed to be received conductor L1. The recess 3 is also dimensioned such that the conductor L1 partially or can be completely absorbed in its diameter.

Ein Leiter setzt sich in aller Regel aus einer Leiterseele und ggf. aus einer darüber angeordneten Leiterisolierung zusammen. Daraus ergeben sich ein Durchmesser für die Leiterseele und ein Durchmesser für die Leiterisolierung. Bei der Aufnahme des Leiters L1 im Kontaktstück 1 ist dabei die Aufnahme der Leiterseele, sprich der zugehörige Durchmesser, von wesentlicher Relevanz. Je nach Dimensionierung der Ausnehmung 3, der Schenkel 5 und der Durchmesser der Leiterseele, kann bei geklemmtem Leiter eine auftretende Federwirkung der Schenkel 5 kontaktwirksam genutzt werden.A ladder usually consists of a ladder core and possibly from a conductor insulation arranged above together. This results in a diameter for the conductor core and a diameter for the conductor insulation. In the Recording the conductor L1 in the contact piece 1 is the recording the conductor core, ie the corresponding diameter of essential relevance. Depending on the dimensions of the recess 3, the leg 5 and the diameter of the conductor core, can with clamped conductor an occurring spring effect of Leg 5 are used effectively contact.

Wird eine Kraft K auf den so platzierten Leiter L1 senkrecht oder annähernd senkrecht zum Grundkörper 2 aufgebracht, bewirkt die Längskante 4 eine Unterbrechung der Isolation des Leiters L1. Die Isolation reißt demnach entlang des Leiters L1 ein und wird unter der einwirkenden Kraft K zum Teil seitlich der Leiterseele in die Richtung der Krafteinwirkung und zum Teil in die Aussparung 3 hinein verdrängt und ggf. zum Teil weggequetscht.If a force K is perpendicular to the thus placed conductor L1 or applied approximately perpendicular to the base body 2 causes the longitudinal edge 4 an interruption of the insulation of the Conductor L1. The insulation therefore tears along the conductor L1 and is under the applied force K in part laterally the conductor soul in the direction of the force and partly displaced into the recess 3 and possibly for Part squeezed off.

Die Längskante 4 kann auch auf beiden Längsseiten der Ausnehmung 3 vorgesehen werden, wobei verschiedene Kantenformen und -ausprägungen, wie beispielsweise eine Sägezahn-, eine Wellen- oder auch eine Schneidenkante möglich sind. Bei dem so aufgenommenen Leiter L1 stellen die durch die Ausnehmung 3 gebildeten Schenkel 5 des Grundkörpers 2 mit dem aufgenommenen ersten Leiter L1 eine elektrisch leitende Druckverbindung her.The longitudinal edge 4 can also be on both longitudinal sides of the recess 3 are provided, with different edge shapes and expressions, such as a sawtooth, a wave or a cutting edge are possible.
