Description
Die Erfindung betrifft ein Terminal zur Kontaktierung eines elektrischen Leiters.The invention relates to a terminal for contacting an electrical conductor.
Terminals zur Kontaktierung eines elektrischen Leiters oder anderer elektrischer Bauteile sind aus dem Stand der Technik umfänglich bekannt. So offenbart beispielsweise die
Aus der
Aus der
Hierbei werden einzelne Leitungen in einen IDC-Stecker (IDC = insulation displacement connection) von oben eingelegt und mit einem Werkzeug, das Druck in Vertikalrichtung von oben nach unten ausübt, kontaktiert. Die elektrische Verbindung der Kontakte mit den Leitungen wird hierbei durch Einpressen der Leitungen in Schneidklemmen von oben nach unten hergestellt. Dabei wird das Isolationsmaterial der Leitungen von den Schneiden oder Flanken der Schneidklemmen eingeschnitten und verdrängt und die freigelegten Kupferlitzen werden durch die Federwirkung dieser Flanken dauerhaft eingeklemmt.Here, individual lines are inserted into an IDC connector (IDC = insulation displacement connection) from above and contacted with a tool that exerts pressure in the vertical direction from top to bottom. The electrical connection of the contacts with the lines is hereby made by pressing the wires in insulation displacement from top to bottom. The insulating material of the lines is cut and displaced by the cutting edges or flanks of the insulation displacement and the exposed copper strands are permanently clamped by the spring action of these flanks.
Bei sämtlichen dieser Schneidklemmverbindungen werden die Leitungen jeweils von oben nach unten in entsprechende Öffnungen eingelegt und auch von oben nach unten durch Ausübung einer Fügekraft mittels Schneidklemm-Technik kontaktiert und fixiert.In all of these insulation displacement connections, the lines are each inserted from top to bottom in corresponding openings and also contacted and fixed from top to bottom by exercising a joining force using insulation displacement technology.
Hierbei wird eine Kraft von oben nach unten ausgeübt. Sehr oft sind die Gehäuse, Stecker und dergleichen, in denen die Leitungen kontaktiert werden müssen, auf Leiterplatten befestigt, sodass die Kraft auf eine Leiterplatte ausgeübt wird, was in vielen Fällen unerwünscht ist. Da außerdem die Schneid-Klemm-Kontaktierung in die gleiche Richtung erfolgt wie das Einlegen der Leitung, besteht die Gefahr, dass die Leitungen aus der SchneidKlemmverbindung - zumindest dann, wenn eine hohe Zugkraft auf die Leitungen ausgeübt wird - entfernt werden können und so die elektrische Kontaktierung unterbrochen wird.Here, a force is exerted from top to bottom. Very often, the housings, plugs and the like, in which the leads must be contacted, are mounted on printed circuit boards, so that the force is exerted on a printed circuit board, which is undesirable in many cases. In addition, since the insulation displacement contact in the same direction as the insertion of the line, there is a risk that the lines from the insulation displacement connection - at least when a high tensile force is exerted on the lines - can be removed and so the electrical Contacting is interrupted.
Das erfindungsgemäße Terminal zur Kontaktierung eines elektrischen Leiters mit den Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass die elektrische Leitung zwar von oben in ein Gehäuse einlegbar ist, wozu die längliche Öffnung zum Einlegen des elektrischen Leiters vorgesehen ist, jedoch die Schneid-Klemm-Kontaktierung von der Seite her und im Wesentlichen senkrecht zur länglichen Öffnung und zur Einlegerichtung erfolgt. Auf diese Weise wird bei der Schneid-Klemm-Kontaktierung kein Druck beispielsweise auf eine Leiterplatte, auf der das Terminal montiert ist, ausgeübt. Die Schneid-Klemm-Kontaktierung kann durch ein zangenartiges Werkzeug erfolgen. Dies kann insbesondere auch automatisch mittels eines Handhabungsautomaten beispielsweise in einer Fertigungsstraße geschehen, sodass das erfindungsgemäße Terminal einer automatischen Fertigung gut zugänglich ist. Darüber hinaus wird durch die quer zu Öffnung verlaufende Schneid-Klemm-Kontaktierung ein sicheres Halten des elektrischen Leiters ermöglicht. Insbesondere kann der elektrische Leiter nicht mehr - auch nicht unter Ausübung einer größeren Kraft - aus der länglichen Öffnung herausgezogen werden, wie dies bei den aus dem Stand der Technik bekannten elektrischen Schneid-Klemm-Verbindungen möglich ist. Das erfindungsgemäße Terminal ermöglicht damit nicht nur eine einfache und automatische Fertigung, sondern auch eine sichere und nahezu zerstörungsfreie Befestigung eines mittels Schneid-Klemm-Kontaktierung befestigten Leiters.The inventive terminal for contacting an electrical conductor with the features of claim 1 has the advantage that the Although electrical line can be inserted from above into a housing, for which purpose the elongated opening is provided for inserting the electrical conductor, but the insulation displacement contacting takes place from the side and substantially perpendicular to the elongated opening and the insertion direction. In this way, no pressure is exerted, for example, on a printed circuit board on which the terminal is mounted in the insulation displacement contact. The insulation displacement contact can be done by a pliers-like tool. This can in particular also be done automatically by means of an automatic handling machine, for example in a production line, so that the terminal according to the invention is readily accessible to automatic production. In addition, a secure holding of the electrical conductor is made possible by the transverse to opening extending insulation displacement contact. In particular, the electrical conductor can not be pulled out of the oblong opening, not even when a larger force is exerted, as is possible with the electrical insulation displacement connections known from the prior art. The terminal according to the invention thus enables not only a simple and automatic production, but also a secure and virtually nondestructive attachment of a conductor fastened by means of insulation displacement contacting.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des in dem unabhängigen Anspruch 1 angegebenen Terminals möglich. Der Erfindung nach sind zwei Schneidklemmen vorgesehen, die jeweils in Leiterrichtung gesehen am vorderen und am hinteren Ende der länglichen Öffnung positioniert sind. Hierdurch wird nicht nur die Kontaktierung verbessert, sondern der elektrische Leiter gleichzeitig auch in der länglichen Öffnung besonders gut fixiert und damit gehalten.The measures listed in the dependent claims advantageous refinements and improvements of the independent claim 1 terminal are possible. According to the invention, two insulation displacement terminals are provided, which are each positioned in the conductor direction at the front and at the rear end of the elongated opening. As a result, not only the contact is improved, but the electrical conductor is also very well fixed and held in the elongated opening at the same time.
Dabei sind die beiden Schneidklemmen der Erfindung nach an einem U-förmigen Bügel angeordnet und mit diesem gemeinsam zur Ausbildung von Schneid-Klemm-Kontakten quer zur Öffnung in Richtung des elektrischen Leiters bewegbar. Auf diese Weise wird mit einer einzigen "Zangenbewegung" eine Kontaktierung und Befestigung des elektrischen Leiters in der länglichen Öffnung und damit in dem Gehäuse des Terminals ermöglicht.The two cutting clamps of the invention are arranged according to a U-shaped bracket and movable with this together to form insulation displacement contacts transversely to the opening in the direction of the electrical conductor. In this way, with a single "forceps movement" contacting and attachment of the electrical conductor in the elongated opening and thus in the housing of the terminal allows.

Der Erfindung nach sind der U-förmige Bügel und das Anschlusselement einstückig miteinander verbunden. Die Kontaktelemente können Einpresskontaktelemente sein, sie können aber auch als zur Oberflächenverlötung ausgebildete Lötkontaktelemente ausgebildet sein.
Eine vorteilhafte Ausgestaltung sieht vor, dass das Anschlusselement ein im wesentlichen im rechten Winkel von dem U-förmigen Bügel abgebogenes Anschlussblech ist, an dessen unteren, dem U-förmigen Bügel abgewandten Seiten die Kontaktelemente angeordnet sind. Dies ermöglicht eine einfache Montage und eine besonders gute Kontaktierung.
Vorteilhafterweise ist vorgesehen, dass für den U-förmigen Bügel mit den Schneidklemmkontakten und das Anschlusselement in dem Gehäuse Führungen vorgesehen sind, welche ein Einschieben des U-förmigen Bügels zusammen mit den Schneid-Klemm-Kontakten und mit dem Anschlusselement in das Gehäuse ermöglichen. Wenn in diesem Falle die Kontaktelemente bereits beispielsweise auf einer Leiterplatte befestigt sind, wird umgekehrt das Gehäuse relativ zum U-förmigen Bügel verschoben, wobei wiederum die Schneid-Klemm-Kontakte in den Leiter eindringen und dabei das Isolationsmaterial des Leiters von den Schneiden oder Flanken der Schneidklemmen eingeschnitten und verdrängt wird und die freigelegten Kupferlitzen durch die Federwirkung dieser Flanken dauerhaft eingeklemmt werden.The U-shaped bracket of the invention according to connected to a connection element, which on its side facing away from the U-shaped bracket contact elements for contacting with printed conductors of a printed circuit board, In this way, an immediate contacting of the electrical conductor with corresponding tracks of a circuit board is possible. According to the invention, the U-shaped bracket and the connecting element are integrally connected to each other. The contact elements may be press-fit contact elements, but they may also be designed as solder contact elements designed for surface soldering.
An advantageous embodiment provides that the connection element is a bent substantially at right angles to the U-shaped bracket connection plate, at the bottom, the U-shaped bracket opposite sides, the contact elements are arranged. This allows easy installation and a particularly good contact.
Advantageously, it is provided that guides are provided for the U-shaped bracket with the insulation displacement contacts and the connection element in the housing, which allow insertion of the U-shaped bracket together with the insulation displacement contacts and the connection element in the housing. If, in this case, the contact elements are already attached, for example, on a circuit board, the reverse is the Housing displaced relative to the U-shaped bracket, in turn, the insulation displacement contacts penetrate into the conductor while the insulating material of the conductor is cut and displaced by the edges or flanks of the insulation displacement and the exposed copper strands are permanently clamped by the spring action of these edges ,
Besonders bevorzugt ist vorgesehen, dass die längliche Öffnung in Öffnungsrichtung eine Verjüngung aufweist, die dem Festklemmen eines einzulegenden elektrischen Leiters dient. Auf diese Weise wird der Leiter in der länglichen Öffnung bereits festgehalten noch bevor die Schneid-Klemm-Kontaktierung erfolgt ist. Auch während der Schneid-Klemm-Kontaktierung erweist sich diese Verjüngung als besonders vorteilhaft.Particularly preferably, it is provided that the elongated opening has a taper in the opening direction, which serves to clamp an electrical conductor to be inserted. In this way, the conductor is already held in the elongated opening before the insulation displacement contact is made. Even during the insulation displacement contact, this taper proves to be particularly advantageous.

Ein als Ganzes mit 100 bezeichnetes Terminal weist ein Gehäuse 110 auf, das beispielsweise aus Kunststoff besteht, In diesem Gehäuse ist eine von oben zugängliche längliche Öffnung 120 vorgesehen, welche eine Verjüngung 122 aufweist. Seitlich an dem Gehäuse angeordnet ist ein U-förmiger Bügel 200, an dem jeweils Schneid-Klemmen 210 und 220 angeordnet sind.

Der Vorteil des vorstehend beschriebenen Terminals ist 100 es, dass es auch einer automatischen Fertigung zugänglich ist. Der Druck zur Kontaktierung wird dabei nicht auf die Leiterplatte 600, 700 ausgeübt, sondern zangenartig auf das Gehäuse 110 und den U-förmigen Bügel 200. Diese seitliche Druckausübung hat den großen Vorteil, dass sie einer automatischen Fertigung besser zugänglich ist. Darüber hinaus ist eine Beschädigung der Leiterplatte ausgeschlossen. Die seitliche Kontaktierung ermöglicht darüber hinaus ein wesentlich sichereres Halten des Leiters 400 in dem Gehäuse 110 des Terminals 100. Der Leiter 400 ist gewissermaßen in dem Terminal 100 "verriegelt", indem die beiden Schneid-Klemmen, die am vorderen und am hinteren Ende der länglichen Öffnung 120 angeordnet sind, quer zur Öffnung verlaufen und so den Leiter 400 praktisch unlösbar in dem Terminal 100 halten.The advantage of the terminal described above is that it is also accessible to automated manufacturing.
