Description

Terminal zur ontaktlerung eines elektrischen Leiters  Terminal for ontaktlerung an electrical conductor
Die Erfindung betrifft ein Terminal zur Kontaktiemng 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 DE 202004 020 191 U1 eine Einschub- Kontakfierung zwische einem Wickelgut, z.B. der Spule eines Transformators, und einer Leiterplatte mittels einer Schneidkiemme. Die vorzugsweise mit Klemm-Zungen versehene Schneidkiemme wird in eine auf einer Leiterplatte elektrisch und mechanisch befestigte Steckbrücke eingeschoben, wodurch sich eine sichere elektrische Verbindung durch das elastische Zurückbiegen der Klemm-Zungen sowie durch das mechanische Einschneiden der Klemm-Zungen in die Steckbrücke ergibt. Terminals for contacting an electrical conductor or other electrical components are well known in the art. For example, DE 202004 020 191 U1 discloses a plug-in contact between a winding material, e.g. the coil of a transformer, and a circuit board by means of a Schneidkiemme. The Schneidkiemme preferably provided with clamping tongues is inserted into a jumper on an electrically and mechanically fixed jumper, resulting in a secure electrical connection by the elastic bending back of the clamping tongues and by the mechanical cutting of the clamping tongues in the jumper.
Aus der DE 10 2010 033 545 A1 geht eine Vorrichtung zur Kontaktierung elektrischer Leiter mit einem Gehäuse und je einer Schneidkiemme hervor. Die Schneidkiemme ist in das Gehäuse eingesetzt. Aus der EP 1 291 984 AI geht ein Verfahren zur Herstellung einer elektrischen Schneidklernmverbindung. hervor. From DE 10 2010 033 545 A1 discloses a device for contacting electrical conductors with a housing and a Schneidkiemme forth. The Schneidkiemme is inserted into the housing. From EP 1 291 984 A1, a process for the production of an electrical Schneidklernmverbindung goes. out.
Hierbei werden einzelne Leitungen in einen IDC-Stecker (IDC - insulation. dispiacemerrt 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 Schnesdklemmen eingeschnitten und verdrängt und die freigelegten Kupferlitzen werden durch die Federwirkung dieser Flanken dauerhaft eingeklemmt. In this case, individual lines are inserted into an IDC plug (IDC - insulation. Dispiacemerrt 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 in this case by pressing the lines made in cutting clamps from top to bottom. In this case, the insulation material of the lines is cut and displaced by the edges or flanks of Schnesdklemmen and the exposed copper strands are permanently clamped by the spring action of these flanks.
Bei sämtlichen dieser Schneidklemmverbindungen werden die Leitungen jeweils vo oben nach unten in entsprechende Öffnungen eingelegt und auch von oben nach unten durch Ausübung einer Fügekraft mittels Schneidklemm- Technlk 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 by means of 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 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. As well as the
Schneid- iemm-Kontaktierung in die gleiche Richtung erfolgt wie das Einlegen der Leitung, besteht die Gefahr, dass die Leitungen aus der Schneid- Klemmverbindung - zumindest dann, wenn eine hohe Zugkraft auf die Leitungen ausgeübt wird - entfernt werden können und so die elektrische Kontaktierung unterbrochen wird. Cutting-in contacting 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 contact is interrupted.
Offenbarung der Erfindung Disclosure of the invention
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 Schneld- temrn-Köniakiierung von der Seite her und im Wesentlichen senkrecht zur länglichen Öffnung und zur Einlegerichtung erfolgt Auf diese Weise wird bei der Schneid~ !emm~Konfaktierung kein Druck beispielsweise auf eine Leiterplatte, auf der das Terminal montiert ist, ausgeübt. Die Schneid- lemm-Kontaktierung kann durch ein zangenartiges Werkzeug erfolgen. Dies kann insbesondere auch automatisch mittels eines Handhabungsautomaien beispielsweise in einer Fertigungsstraße geschehen, sodass das erfindungsgemäße Terminal einer automatischen Fertigung gut zugänglich ist. Daruber hinaus wird durch die quer zu Öffnung verlaufende Schneid- Kiemm-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-Kfemm-Verbindungen möglich ist. Das erfindungsgemäße Terminal ermöglicht damit nicht nur eine einfache und automatische Fertigung, sondern auch eine sichere und nahez zerstörungsfreie Befestigung eines mittels Schnes'd-Kfemm- ontaktlerang 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 Is what the elongated opening for inserting the electrical conductor is provided, however, the Schnürstemrn-Köniakiierung from the side and substantially perpendicular to the elongated opening and the insertion direction takes place in this way is at For example, no pressure is exerted on a printed circuit board on which the terminal is mounted. The cutting clamp contacting can be done by a pliers-like tool. This can in particular also be done automatically by means of a handling automation, for example in a production line, so that the inventive terminal is easily accessible to automatic production. In addition, a secure hold of the electrical conductor is made possible by the transverse to opening cutting Kiemm-contacting. In particular, the electrical conductor can not be withdrawn from the oblong opening even with the application of a greater force, as is possible with the electrical cutting-off-kink connections known from the prior art. So that the terminal according to the invention not only enables a simple and automatic production, but also a safe and nahez destructive attachment of a fortified conductor ontaktlerang means schnes' d-Kfemm-.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des in dem unabhängigen Anspruch 1 angegebenen Terminals möglich. The measures listed in the dependent claims advantageous refinements and improvements of the independent claim 1 terminal are possible.
So sieht eine vorteilhafte Ausgestaltung beispielsweise vor, dass wenigstens zwei Schneldktemrnen vorgesehen sind, die jeweils in Leiterrichtung gesehen am vorderen und am hinteren Ende der länglichen Öffnung positioniert sind. Hierdurch wird nicht nur die Konfaktierung verbessert, sondern der elektrische Leiter gleichzeitig auch in der länglichen Öffnung besonders gut fixiert und damit gehalten. Dabei sind die beiden Schneidklemmen vorzugsweise an einem U-förmigen Bügel angeordnet und mit diesem gemeinsam zur Ausbildung von Schneid- Kiemm-Kontak en 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. Thus, an advantageous embodiment, for example, provides that at least two Schneldktemrnen 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 Konfaktierung is improved, but the electrical conductor at the same time also very well fixed in the elongated opening and thus held. In this case, the two cutting clamps are preferably arranged on a U-shaped bracket and movable with this together to form cutting Kiemm Kontak s transverse 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 U-förmige Bügel ist vorteilhafterweise mit einem Änschiusselement verbunden, weiches auf seiner dem U-förmigen Bügel abgewandten Seite Kontaktelemente zur Kontaktierung mit Leiterbahnen einer Leiterplatte aufweist, Auf diese Weise ist eine unmittelbare Kontaktierung des elektrischen Leiters mit entsprechenden Leiterbahnen einer Leiterplatte möglich. The U-shaped bracket is advantageously connected to a Änschiusselement, soft 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.
Besonders vorteilhaft ist es, wenn der U-förmige Bügel und das Anschlusselement einstückig miteinander verbunden sind. It when the U-shaped bracket and the connection element are integrally connected with each other is particularly advantageous.
Die Kontaktelemente können Einpresskontakteiemente sein, sie können aber auch als zur Oberflächeriverlotung ausgebildete Lötkontaktelemente ausgebildet sein. The contact elements can be Einpresskontakteiemente, but they can also be designed as designed for Oberflächeriverlotung solder contact elements.
Eine vorteilhafte Ausgestaltung sieht vor, dass das Änschiusselement ein im wesentlichen im rechten Winkel von dem U-förmigen Bügel abgebogenes Änschlussblech ist, an dessen unteren, dem U-förmigen Bügel abgewandten Seiten die Kontaktelemente angeordnet sind. Dies ermöglicht eine einfache Montage und eine besonders gute Kontaktierung. An advantageous embodiment provides that the Änschiusselement is a substantially at right angles from the U-shaped bracket bent Änschlussblech, at the bottom, the U-shaped bracket facing away from the contact elements are arranged. This allows easy installation and a particularly good contact.
Vorteilhafterweise ist vorgesehen, dass für den U-förmigen Bügel mit den Schneidklemmkontakten und das Änschlusseiement in dem Gehäuse Führungen vorgesehen sind, welche ein Einschieben des U-förmigen Bügels zusammen mit den Schneid-Klemm-Koniakten und mit dem Änschiusselement in das Gehäuse ermöglichen. Wenn in diesem Falle die Kontaktelemente bereits beispielsweise auf einer Leiterplatte befestigt sind, wird umgekehrt da Gehäuse relativ zum ü-förmigen Bügel verschoben, wobei wiederum die Schneid-Klemm-Kontakte in den Leiter eindringen und dabei das Isolaöons- material des Leiters vo den Schneiden oder Flanken der Schneidklemmen eingeschnitten und verdrängt wird und die freigefegten Kupferlitzen durch die Federwirkung dieser Flanken dauerhaft eingeklemmt werden> Advantageously, it is provided that guides are provided for the U-shaped bracket with the insulation displacement contacts and the Änschlusseiement in the housing, which allow insertion of the U-shaped bracket together with the insulation displacement Koniakten and with the Änschiusselement in the housing. If, in this case, the contact elements are already attached, for example, on a circuit board, is vice versa there Housing displaced relative to the U-shaped bracket, in turn, the insulation displacement contacts penetrate into the conductor while the Isolaöons- material of the conductor is cut from the cutting edges or flanks of the insulation displacement and displaced and the freed copper strands by the spring action of these flanks permanently to be trapped>
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 Letter in der länglichen Öffnung bereits festgehalten noch bevor die Schneid- lemm- Kontakfierung erfolgt ist. Auch während der Schneid- Iemm-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 letter is already held in the elongated opening even before the cutting clamp contact has taken place. This taper also proves to be particularly advantageous during cutting-contacting.
Das Gehäuse besteht vorzugsweise aus einem Kunststoff. The housing is preferably made of a plastic.

Ausführungsformen der Erfindung Embodiments of the invention
Ein als Ganzes mit 100 bezeichnetes Terminal weist ein Gehäuse 1 10 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 äst ein U-förmiger Bügel 200, a dem jeweils Schneid-Klemmen 210 und 220 angeordnet sind, Mit dem U~förmigen Bügel 200 einstückig verbunden ist ein Änschlusseie- ment 300. Dieses Anschiusseiement 300 weist beispielsweise Einpresskontakte 30 , 302, 303 und 304 auf. Diese Einpresskontakfe dienen der Einpres- sung in entsprechende Öffnungen auf einer beispielsweise Leiterplatte (siehe Fig. 5a bis c, Fig. 6). Wie Flg. 1 ferner zu entnehmen ist, sind in dem Gehäuse 1 10 Führungen 150 und 180 für den U-förmigen Bügel 200 und die Schneid-KlemnvKontakte 210, 220 vorgesehen, die ein seitliches Einschieben der Schneid-Klemm-Koniakie in das Gehäuse entlang einer Richtung ermöglichen, die i den Figuren mit einem Pfeil R dargestellt ist. Wie insbesondere der Fig. 2 zu entnehmen ist, weisen die Schneid- lemm-Kontakte 220 eine gabelförmige Gestalt mit Schneidffanken 221 auf, die das Isolati- onsmaterial 405 eines Leiters 400 einschneiden und verdrängen und die freigelegten Kupferlitzen 410 ebenfalls teilweise einschneiden oder zumindest aufgrund der Federwirkung der beiden Schneiden der Schneidklemme 220 klemmen. Dies ist schematisch in Fig. 3 dargestellt, welche de kontaktierten und befestigten Zustand eines elektrischen Leiters in dem Terminal 100 zeigt. In Fig. 3 ist darüber hinaus besonders gut zu erkennen, wie der Vorsprung 122 den elektrischen Leiter in einer für die Schneid-Klemm- ontakfierung günstigen Position hält und insbesondere vor einem Herausfallen aus der länglichen Öffnung 120 sichert. Nachdem der elektrische Leiter auf diese Weise koniaktierl und befestigt wurde,, was beispielsweise mittels einer entsprechenden Zange geschehen kann, die ein Kraft auf das ü-förmige Element 200 und das Gehäuse 110 ausübt und auf diese Weise ein Hineinschleben der Schneid-Klemmen 210, 220 unter gleichzeitiger Kontaktierung und Fixierung des elektrischen Leiters in dem Gehäuse hervorruft, A designated as a whole with 100 terminal has a housing 1 10, which consists for example of plastic, in this housing is provided from the top accessible elongated opening 120, which has a taper 122. Arranged laterally on the housing is a U-shaped bracket 200, which is provided with cutting clamps 210 and 220. An attachment segment 300 is integrally connected to the U-shaped bracket 200. This connection element 300 has, for example, press-fit contacts 30, 302 , 303 and 304 on. These press-fit contacts serve to press into corresponding openings on, for example, a printed circuit board (see FIGS. 5 a to c, FIG. 6). Like Flg. 1, 10 guides 150 and 180 are provided in the housing 1 for the U-shaped bracket 200 and the cutting clamp contacts 210, 220, which permit lateral insertion of the insulation displacement cone into the housing along one direction , which is shown in the figures with an arrow R. As can be seen in particular from FIG. 2, the cutting clamp contacts 220 have a forked shape with cutting edges 221, which cut and displace the insulating material 405 of a conductor 400 and also partly cut the exposed copper strands 410 or at least due to the Clamp the spring action of the two cutting edges of the cutting clamp 220. This is schematically illustrated in FIG. 3, which shows the contacted and attached state of an electrical conductor in the terminal 100. In addition, FIG. 3 shows particularly clearly how the projection 122 holds the electrical conductor in a position which is favorable for the cutting clamping ontakfierung and in particular against falling out of the elongated opening 120 secures. After the electrical conductor has been conected and secured in this manner, which can be done, for example, by means of a corresponding pair of pliers which exerts a force on the U-shaped element 200 and the housing 110 and in this way injects the cutting terminals 210, 220 causes simultaneous contacting and fixing of the electrical conductor in the housing,
In Fig. 4 ist eine andere Ausführungsform eines erfindungsgemäß-en Terminals dargestellt, weiche sich von dem in Fig. 1 bis 3 dargestellten durch die Art der Kontaktierung auf einer Leiterplatte unterscheidet. Statt Einpresskontakten sind hier entsprechende Öffnungen 30®, 307, 308, 309 zur Aufnahme von Lot vorgesehen, mittels denen das Anschlusselement 300 auf einer Leiterplatte durch Oberflächeniötung befestigbar ist, im Übrigen sind gleiche Elemente in Fig. 4 mit den gleichen Bezugszeichen wie in den Fig. 1 bis 3 dargestellt, sodass auf die Ausführungen zu diesen Elementen auf das Vorstehende Bezug genommen wird. FIG. 4 shows another embodiment of a terminal according to the invention, which differs from that shown in FIGS. 1 to 3 by the type of contacting on a printed circuit board. Instead of press-in contacts, corresponding openings 30®, 307, 308, 309 are provided here for receiving solder, by means of which the connection element 300 can be fastened on a circuit board by Oberflächeniötung, otherwise the same elements in Fig. 4 with the same reference numerals as in Figs 1 to 3, so that the comments on these elements are referred to the above.
Die Befestigung des Terminals auf Leiterplatten und die Kontaktierung und Befestigung eines Leiters wird nachfolgend in Verbindung mit den Fig, 5a~d und 8 erläutert. The attachment of the terminal on printed circuit boards and the contacting and attachment of a conductor will be explained below in connection with the Fig, 5a ~ d and 8.
Zunächst wird ein Terminal 100 auf einer Leiterplatte 800 befestigt. Hierzu sind in der Leiterplatte 600 Öffnungen 601 , 602, 603, 804 vorgesehen, welche ein Einpressen der Elnpresskontakte 301 , 302, 303, 304 ermöglicht (siehe Fig. 5a), Nachdem das Terminal 100 auf diese Weise auf der Leiterplatte 600 befestigt wurde (Fig, 5b), wird ein elektrischer Leiter 400 in die längliche Öffnung 12 des Terminals gelegt und dort aufgrund der Verjüngung 122 (Fig, 5c) gehalten. Sodann wird mittels eines (nicht dargestellten) zangenartigen Werkzeugs die Schneid-Klemm-Kontaktierung durch seitliches Einschieben der Schneid-Klemmen 2 0, 220 hergestellt. Durch die zangenartige Bewegung wird eine Kraft auf den U-förmigen Bügel 200 und auf die ihm gegenüberliegende Gehäuseselte 111 des Gehäuses 110 ausgeübt. Auf diese Weise wird der Leiter 400 in dem Terminal 100· kontaktiert und befestigt. Fig. 6 zeigt die Verbindung zweier Leiterplatten 600 und 700, auf denen jeweils Terminals angeordnet sind, wobei das auf der Leiterplatte 800 angeordnete Terminal ein Terminal mit Einpresskontakten ist, während das auf der Leiterplatte 700 angeordnete Terminal ein Terminal mit SivlD-Lötkontakten darstellt Der Leiter 400 kann die beiden Leiterplatten 600, 700 verbinden. First, a terminal 100 is mounted on a circuit board 800. For this purpose, 600 openings 601, 602, 603, 804 are provided in the printed circuit board, which allows a pressing in of the pressing contacts 301, 302, 303, 304 (see FIG. 5a), after the terminal 100 has been attached to the printed circuit board 600 in this manner (FIG. Fig. 5b), an electrical conductor 400 is placed in the elongated opening 12 of the terminal and held there due to the taper 122 (Fig, 5c). Then, by means of a (not shown) pliers-like tool, the insulation displacement contact by lateral insertion of the cutting terminals 2 0, 220 produced. Due to the forceps-like movement, a force is exerted on the U-shaped bracket 200 and on the housing 111 of the housing 110 lying opposite it. In this way the conductor 400 is contacted and fixed in the terminal 100. Fig. 6 shows the connection of two printed circuit boards 600 and 700, on each of which terminals are arranged, wherein the arranged on the circuit board 800 terminal is a terminal with press-fit, while arranged on the circuit board 700 terminal is a terminal with SivlD solder contacts The conductor 400 may connect the two circuit boards 600, 700.
Der Vorteil des vorstehend beschriebenen Terminais ist 100 es, dass es auch einer automatischen Fertigung zugänglich ist. Der Druck zur ontaktierung wird dabei nicht auf di Leiterplatte 600, 700 ausgeübt, sondern zangenartig auf das Gehäuse 110 und den U-förm gen 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 oniaktierung 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 beide 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 above described embodiment is that it is also accessible to automated production. The pressure for ontakting is not exercised on the circuit board 600, 700, but pliers-like on the housing 110 and the U-shaped gene strap 200. This lateral pressure has the great advantage that it is more accessible to automatic production Damage to the printed circuit board excluded. The. Lateral engagement also allows much more secure retention of the conductor 400 in the housing 110 of the terminal 100. The conductor 400 is effectively "locked" in the terminal 100 by the two cutting clamps at the front and rear ends of the elongate opening 120 are arranged, transverse to the opening and so keep the conductor 400 practically insoluble in the terminal 100.
