Description

Die Erfindung betrifft ein Leiteranschlußelement zum Anschluß elektrischer Leiter, vorzugsweise für Leiter mit großen Leitungsquerschnitten.The invention relates to a conductor connection element for connecting electrical Conductors, preferably for conductors with large wire cross sections.

Ein derartiges Leiteranschlußelement dient zur lösbaren, schnell und einfach auszuführenden Verbindung von elektrischen Leitern mit elektrischen Schneidklemmkontakten.Such a conductor connection element is used for detachable, quick and easy connection to be made of electrical conductors with electrical IDCs.

Aus der EP 554 810 A2 ist ein elektrischer Steckverbinder zum Anschluß von isolierten elektrischen Leitern bekannt, bei dem die elektrischen Leiter in 2-fach umgelenkten Bohrungen eines Leiterführungselementes geschoben werden und innerhalb der Umlenkung mittels Schneidklemmen kontaktiert werden.EP 554 810 A2 describes an electrical connector for connection of insulated electrical conductors, in which the electrical conductors are known 2-fold deflected holes in a conductor guide element are contacted and within the deflection by means of insulation displacement clamps become.

Ungünstig wirkt sich bei den bekannten Verbindungen mit Schneidklemmen aus, daß einfache Schneidklemmkontakte auf Grund der kleinen Berührungsflächen zwischen den elektrischen Leitern und den schmalen Kontaktschneiden nur begrenzte Stromstärken übertragen können.The known connections with insulation displacement connectors have an unfavorable effect from that simple insulation displacement contacts due to the small contact surfaces between the electrical conductors and the narrow contact blades can only transmit limited currents.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Leiteranschlußelement der eingangs genannten Art dahingehend auszubilden, mit dem eine einfache Montage und Verbindung von elektrischen Leitern ermöglich wird, die auch höhe Ströme übertragen kann. The invention is therefore based on the object of a conductor connecting element of the type mentioned to train with a simple Assembly and connection of electrical conductors is made possible can also transmit high currents.

Diese Aufgabe wird dadurch gelöst, dass ein Anschlußkörper vorgesehen ist, in dem eine U-förmige Leiteraufnahmekammer ausgebildet ist, dass im Anschlußkörper eine Gewindebohrung vorgesehen ist, in die eine Klemmschraube einschraubbar ist, dass der Anschlußkörper mit mindestens einer Schneidklemme versehen ist, und dass ein in die Leiteraufnahmekammer eingelegter elektrischer Leiter beim Einschrauben der Klemmschraube durch diese in die Leiteraufnahmekammer gedrückt wird, wobei die Schneidklemme die Ummantelung des elektrischen Leiters durchtrennt und der Leiter mit der Schneidklemme elektrisch kontaktiert.This object is achieved in that a connection body is provided is in which a U-shaped conductor receiving chamber is formed that in Connection body is provided with a threaded hole into which a clamping screw can be screwed in that the connecting body with at least one Insulation clamp is provided and that one in the conductor receiving chamber inserted electrical conductor when screwing in the clamping screw this is pressed into the conductor receiving chamber, the insulation displacement terminal sever the sheath of the electrical conductor and the conductor with the insulation displacement contact electrically.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 12 angegeben.Advantageous embodiments of the invention are in claims 2-12 specified.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein Leiteranschlußelement mit einer doppelt ausgeführten Schneidklemmenanordnung mit wesentlich höheren Stromstärken beaufschlagt werden kann, wobei die Schneidklemmen symmetrisch zur mittig dazwischen angeordneten Klemmschraube angeordnet sind.
Weiterhin ist durch eine Schneidklemmkontaktierung eine sichere elektrische Kontaktierung gewährleistet, die auch bei größeren Kabelquerschnitten nur geringe Betätigungskräfte erfordert.
Aufgrund der offenen Bauweise des Leiteranschlußelementes, bei der die Kontaktierungsstelle direkt eingesehen werden kann, ist zudem eine einfache visuelle Kontrolle über den Kontaktierungszustand zwischen Schneidklemme und elektrischem Leiter von Vorteil.
Eine vorteilhafte Weiterbildung der Erfindung ergibt sich durch den Einsatz einer Klemmschraube mit einem sich nicht drehenden Druckstück, welches den elektrischen Leiter in die Schneidklemmen drückt, wobei die sonst noch zusätzlich auftretenden Reibungskräfte auf die Ummantelung des elektrischen Leiters durch die sich drehende Klemmschraube vermieden werden. The advantages achieved by the invention consist in particular in the fact that a conductor connection element with a double insulation displacement arrangement can be acted upon with significantly higher currents, the insulation displacement terminals being arranged symmetrically to the clamping screw arranged in the middle.
Furthermore, a secure electrical contact is ensured by an insulation displacement contact, which requires only slight actuation forces even with larger cable cross sections.
Because of the open design of the conductor connection element, in which the contact point can be viewed directly, simple visual control of the contact state between the insulation displacement connector and the electrical conductor is also advantageous.
An advantageous development of the invention results from the use of a clamping screw with a non-rotating thrust piece which presses the electrical conductor into the insulation displacement terminals, the additional frictional forces that occur on the sheathing of the electrical conductor being avoided by the rotating clamping screw.

In der Fig.1a ist in einer perspektivischen Ansicht ein elektrisch leitendes Leiteranschlußelement 1 mit Schneidklemmkontakten 20, die in einem Anschlußkörper 10 verrastet sind, als doppelter oder zweiseitiger Leiteranschluß gezeigt, wobei die obere Hälfte mit einem Schraubanschluß versehen ist, während die untere Hälfte in diesem Beispiel nur mit einem offenen Schneidklemmanschluß versehen ist.
Das Leiteranschlußelement kann in unterschiedlichen Varianten für den zweiten (hier unteren) Anschluß auch für eine Stromschiene, als Crimpanschluß, als einfacher Schraubanschluß oder zum Einlöten vorgesehen sein.
Der Anschlußkörper 10 wird durch zwei mittig miteinander verbundene Schenkel 13 und 14 gebildet, wobei durch die Schenkel und einer rechtwinklig am Schenkel 13 angefügten Anformung 15 eine Leiteraufnahmekammer 12 gebildet wird, in die ein elektrischer Leiter 9 durch eine Öffnung 17 einfügbar ist.1a is a perspective view of an electrically conductive conductor connection element 1 with insulation displacement contacts 20, which are locked in a connection body 10, as a double or double-sided conductor connection, the upper half being provided with a screw connection, while the lower half in this Example is only provided with an open insulation displacement connection.
The conductor connection element can be provided in different variants for the second (here lower) connection also for a busbar, as a crimp connection, as a simple screw connection or for soldering.
The connecting body 10 is formed by two legs 13 and 14 connected to one another in the center, a conductor receiving chamber 12 being formed by the legs and a projection 15 attached at right angles to the leg 13, into which an electrical conductor 9 can be inserted through an opening 17.

In dem Beispiel der Fig. 1b ist der H-förmig ausgebildeter Anschlußkörper 10 gezeigt, wobei in der Anformung 15 eine zentrische Gewindebohrung 16 angeordnet ist.
Weiterhin ist jeweils in den Schmalseiten der Schenkel eine vertiefte Ausnehmung 19 vorgesehen, die einen mittigen Zapfen 26 im Verbindungsbereich der beiden Schenkel aufweist. In diese Ausnehmungen ist je eine Schneidklemme 20 mit einer entsprechenden Bohrung 25 für den Zapfen 26 klemmend einfügbar.
Die inneren verrundeten Konturen der Leiteraufnahmekammer 12 sind an die runde Form der elektrischen Leiter 9 angepasst, während die Außenkontur eine längliche, rechtwinklig ausgeführte Form des Anschlußkörpers aufweist.
In die zentrische Gewindebohrung 16 der Anformung 15 ist in, wie in der Fig. 1a gezeigt, eine Klemmschraube 3 eingeschraubt, die im Bereich der Leiteraufnahmekammer mittels einer aufgerasteten Kunststoffhülse 4 unverlierbar gehalten wird. In the example of FIG. 1b, the H-shaped connecting body 10 is shown, a central threaded bore 16 being arranged in the molding 15.
Furthermore, a recess 19 is provided in each of the narrow sides of the legs, which recess has a central pin 26 in the connection area of the two legs. In each of these recesses, a cutting clamp 20 with a corresponding bore 25 for the pin 26 can be inserted by clamping.
The inner rounded contours of the conductor receiving chamber 12 are adapted to the round shape of the electrical conductors 9, while the outer contour has an elongated, rectangular shape of the connection body.
In the central threaded bore 16 of the projection 15, a clamping screw 3 is screwed in, as shown in FIG. 1a, which is held captively in the area of the conductor receiving chamber by means of a snap-on plastic sleeve 4.

Je nach Drehrichtung der Klemmschraube 3 wird das Ende der Kunststoffhülse 4 höher oder tiefer in der Leiteraufnahmekammer 12 bewegt. Beidseitig der Klemmschraube sind zwei einzelne Schneidklemmen 20 mittels an deren seitlichen Außenkanten angeformten rechteckigen Rastnasen 24, die in die Ausnehmungen 19 eingreifen, im Trägerkörper 10 verrastet. Das komplette Leiteranschlußelement 1 wird zur weiteren Verwendung in eine entsprechend geformte Ausnehmung eines hier nicht gezeigten isolierenden Trägergehäuses eingesetzt, wobei mehrere Leiteranschlußelemente in einem Trägergehäuse aneinanderreihbar sind.
Zur Kontaktierung eines Leiteranschlußelementes 1 mit einem elektrischen Leiter wird der elektrische Leiter in die Öffnung 17 in die Leiteraufnahmekammer 12 in den Bereich zwischen die Schneidklemmen 20 geschoben. Anschließend wird die Klemmschraube 3 mit einem entsprechenden Werkzeug in Richtung der Schneidklemmen gedreht, so dass der elektrische Leiter 9 zwischen die Schneidklemmen 20 beidseitig der Klemmschraube gepreßt wird, wobei die Ummantelung des Leiters jeweils durch die beiden Schneidklemmen zerschnitten wird und ein doppelter elektrischer Kontakt zwischen Leiter und Schneidklemmen sicher gestellt ist, so dass auch hohe Ströme über diese Kontaktierung geleitet werden können.Depending on the direction of rotation of the clamping screw 3, the end of the plastic sleeve 4 is moved higher or lower in the conductor receiving chamber 12. On both sides of the clamping screw, two individual insulation displacement clamps 20 are locked in the carrier body 10 by means of rectangular latching lugs 24 which are formed on their lateral outer edges and which engage in the recesses 19. The complete conductor connection element 1 is inserted for further use in a correspondingly shaped recess in an insulating carrier housing, not shown here, several conductor connection elements being able to be strung together in a carrier housing.
To contact a conductor connection element 1 with an electrical conductor, the electrical conductor is pushed into the opening 17 in the conductor receiving chamber 12 in the area between the insulation displacement terminals 20. The clamping screw 3 is then rotated with a corresponding tool in the direction of the insulation displacement terminals, so that the electrical conductor 9 is pressed between the insulation displacement terminals 20 on both sides of the clamping screw, the sheathing of the conductor being cut by the two insulation displacement terminals and a double electrical contact between the conductor and insulation displacement terminals is ensured, so that even high currents can be conducted via this contact.

In der Fig. 1c ist in einem Längsschnitt durch ein Leiteranschlußelement 1 gezeigt, wie ein elektrischer Leiter 9 von der Klemmschraube 3 in die Schneiden von zwei Schneidklemmen 20 gedrückt wird.1c is a longitudinal section through a conductor connection element 1 shown how an electrical conductor 9 from the clamping screw 3 in the Cutting two insulation piercing clamps 20 is pressed.

In einer Variante zu der Fig. 1a ist in der Fig. 2 ein ansonsten baugleiches Leiteranschlußelement gezeigt, bei dem jedoch zwei Schneidklemmen mittels eines brückenartigen Steges 23 zu einer einstückigen doppelten Schneidklemme 21 miteinander verbunden sind.
Beidseitig des Steges sind die Schneidklemmen U-förmig abgebogen und in entsprechende Ausnehmungen 19 auf den Anschlußkörper 10 des Leiteranschlußelementes aufgerastet. In a variant of FIG. 1a, an otherwise identical conductor connection element is shown in FIG. 2, but in which two insulation displacement terminals are connected to one another by means of a bridge-like web 23 to form a one-piece double insulation displacement terminal 21.
The insulation displacement terminals are bent in a U-shape on both sides of the web and snapped into corresponding recesses 19 on the connecting body 10 of the conductor connecting element.

In der Fig. 3 ist ein Leiteranschlußelement gezeigt, das vorzugsweise eine mittig zur Klemmschraube 3 angeordnete Schneidklemme 22 aufweist. Dabei ist die Schneidklemme aus dem Material des Anschlußkörpers 10 herausgearbeitet.In Fig. 3, a conductor connection element is shown, which is preferably a has a cutting clamp 22 arranged in the center of the clamping screw 3. there is the insulation displacement from the material of the connector body 10 worked out.

In einer Variante von Fig. 3 ist in der Fig. 4 ein Leiteranschlußelement gezeigt, das ebenfalls eine mittig zur Klemmschraube 3 angeordnete Schneidklemme aufweist, die jedoch als separate Schneidklemme 20 durch einen mittigen Schlitz 18 zentral in den Anschlußkörper 10 eingefügt ist.In a variant of FIG. 3, a conductor connection element is shown in FIG. 4, which is also a cutting clamp arranged centrally to the clamping screw 3 has, however, as a separate insulation piercing 20 by a central slot 18 is inserted centrally in the connector body 10.

In einer Variante zur Fig. 4 ist in der Fig. 5 ein Leiteranschlußelement gezeigt, dessen Schneidklemme eine außermittige Lage zur Klemmschraube 3 aufweist, wobei die Schneidklemme 20 ebenfalls in einen Schlitz 18 im Anschlußkörper 10 des Leiteranschlußelementes eingefügt ist.In a variant of FIG. 4, a conductor connection element is shown in FIG. 5, the insulation displacement clamp has an eccentric position to the clamping screw 3 has, the insulation displacement terminal 20 also in a slot 18 in Connection body 10 of the conductor connection element is inserted.

Die Fig. 6 zeigt ein Leiteranschlußelement, bei dem wie in der Fig. 1 zwei einzelne Schneidklemmen 20 vorgesehen sind, wobei jedoch die Klemmschraube 3 eine Variante aufweist.
Unterhalb des Klemmschraubenendes in der Leiteraufnahmekammer 12, ist ein rechteckiges Druckstück 5 vorgesehen, daß vorzugsweise mittels einer nietähnlichen Befestigung drehbar an das Ende der Klemmschraube 3 angefügt ist.
Durch die Anlage eines Teiles des Druckstückes an die innere Wand des Schenkels 13 bleibt das Druckstück unabhängig von der Drehung der Klemmschraube - abgesehen von einer vertikalen Verschiebung - in der vorgesehenen Position.
Weiterhin weist das Druckstück 5 an der der Öffnung 17 des Anschlußkörpers 10 zugewandten Seite eine untere Schräge auf, um ein Einfügen eines elektrischen Leiters in die Leiteraufnahmekammer 12 zu den Schneidklemmen 20 zu erleichtern.
Darüberhinaus sind an den beiden Seiten des Druckstückes, die zu den Schneidklemmen weisen, Nasen 6 angeformt, die mit zunehmendem Einpressen des elektrischen Leiters in die Schneidklemmen 20, in den Schlitzen zwischen den Schneidklemmen geführt werden, womit eine zusätzliche Verdrehsicherung erreicht wird.
Durch den Einsatz des nicht mitdrehenden Druckstückes 5 wird weiterhin die Reibung der Klemmschraube 3 bei der Drehung auf die Ummmantelung vermieden und gleichzeitig der Andruck auf eine größere Fläche des elektrischen Leiters verteilt.FIG. 6 shows a conductor connecting element in which, as in FIG. 1, two individual insulation displacement terminals 20 are provided, but the clamping screw 3 has a variant.
Below the end of the clamping screw in the conductor receiving chamber 12, a rectangular pressure piece 5 is provided, which is preferably rotatably attached to the end of the clamping screw 3 by means of a rivet-like fastening.
By abutting a part of the pressure piece on the inner wall of the leg 13, the pressure piece remains in the intended position regardless of the rotation of the clamping screw - apart from a vertical displacement.
Furthermore, the pressure piece 5 has a lower bevel on the side facing the opening 17 of the connection body 10 in order to facilitate insertion of an electrical conductor into the conductor receiving chamber 12 to the insulation displacement terminals 20.
In addition, lugs 6 are formed on the two sides of the pressure piece, which point towards the insulation displacement clamps, and are guided in the slots between the insulation displacement clamps as the electrical conductor is pressed into the insulation displacement clamps 20, thus providing additional security against rotation.
By using the non-rotating thrust piece 5, the friction of the clamping screw 3 during rotation on the sheathing is further avoided and, at the same time, the pressure is distributed over a larger area of the electrical conductor.

In der Fig. 7 ist eine weitere Variante des Leiteranschlußelementes gezeigt, bei der die Klemmschraube 7 in eine Gewindebohrung 16 eines vergrößert ausgebildeten Schenkels 13 des Trägerkörpers 11 geschraubt wird, wobei mit der Klemmschraube ein Druckdeckel 8 auf einen zwischen den Schneidklemmen 20 angeordneten elektrischen Leiter (9) abgesenkt wird und den Leiter zwischen die Schneiden preßt.7 shows a further variant of the conductor connection element, in which the clamping screw 7 in a threaded bore 16 enlarged trained leg 13 of the support body 11 is screwed, with the clamping screw a pressure cover 8 on a between the Insulation clamps 20 arranged electrical conductor (9) is lowered and presses the conductor between the cutting edges.
