Description

Die Erfindung betrifft ein Kontaktelement mit einem Anschluß für Litzenleiter, insbesondere Kontaktelement für hohe Ströme, das mit einem Anschlußende versehen ist, wobei das Anschlußende eine Querbohrung aufweist, in die der Litzenleiter einschiebbar ist, und wobei eine senkrecht zur Querbohrung angeordnete Gewindebohrung vorgesehen ist, die bis in die Querbohrung reicht, und eine mit einer Kegelspitze versehene Klemmschraube in die Gewindebohrung einschraubbar ist.The invention relates to a contact element with a connection for stranded conductors, in particular contact element for high currents, that with a connection end is provided, wherein the connection end has a transverse bore into which the Stranded wire can be inserted, and one arranged perpendicular to the transverse bore Threaded hole is provided, which extends into the cross hole, and a clamping screw with a tapered tip into the threaded hole can be screwed in.

An derartigen Kontaktelementen sollen die Leiter mechanisch befestigt und elektrisch mit dem Kontaktelement verbunden werden. Neben einer sicheren Klemmung muß die Kontaktkraft dauerhaft aufrechterhalten werden. Der Leiter soll dabei zwischen Metallflächen ohne unzulässige Beschädigung geklemmt werden und wieder lösbar sein.The conductors are to be mechanically fastened to such contact elements and be electrically connected to the contact element. In addition to a safe Clamping the contact force must be maintained permanently. The leader should be clamped between metal surfaces without undue damage become and be solvable again.

Es sind Anschlußklemmen bekannt, die für eine um 90° abgewinkelte Zuführung/Ableitung des jeweiligen Leiters als Bolzenklemme ausgebildet sind oder deren Anschluß über eine Schraube in einer Gewindebohrung am Kontaktelement erfolgt. Der Leiter muß dabei zum Anklemmen mit einem Kabelschuh versehen werden. Dieser wird auf den Leiter aufgequetscht oder aufgepreßt. Das ist nur mit speziellen Werkzeugen (Zangen) möglich. Diese benötigen bei einer Vorortmontage wegen ihrer großen Hebelarme viel Platz und sind teuer. Auch hydraulisch betätigte Werkzeuge sind noch verhältnismäßig groß, schwer und haben einen hohen Anschaffungspreis.There are terminals known for a 90 ° angled feed / discharge of the respective conductor are designed as a bolt clamp or their connection via a screw in a threaded hole on the contact element he follows. The conductor must be provided with a cable lug for connection become. This is squeezed or pressed onto the conductor. The is only possible with special tools (pliers). They need one On-site assembly because of their large lever arms takes up a lot of space and is expensive. Also Hydraulically operated tools are still relatively large, heavy and have a high purchase price.

Die großen Kabelschuhabmessungen bedingen einen hohen Platzbedart je Anschluß. Die Klemmstelle muß von außen zugänglich sein, da die Befestigungsmittel (Mutter oder Kiemmschraube) angesetzt und mit den dafür vorgesehenen Werkzeugen mit dem vorgegebenen Anzugsmoment montiert werden müssen. Ein anschließender Schutz der Klemmstelle im bestimmungsgemäßen Zustand (unter elektrischer Spannung) gegen Berühren erfordert einen zusätzlichen Aufwand.The large cable lug dimensions require a large amount of space Connection. The clamping point must be accessible from the outside as the fasteners (Nut or gill screw) and with the provided Tools with the specified tightening torque have to. Subsequent protection of the terminal point as intended Condition (under electrical voltage) against touching requires an additional one Expenditure.

Aus der US 1 064 920 ist ein Kontaktelement aus Isoliermaterial für die Verbindung mehrerer abisolierter Leiter bekannt, dessen Anschlußende mit einer Querbohrung versehen ist, in die die abisolierten Leiter einschiebbar sind. Dabei weist das Anschlußende eine Gewindebohrung auf, in die eine mit einer Kegelspitze versehene Klemmschraube einschraubbar ist, die auf die abisolierten Leiter einwirkt.From US 1 064 920 is a contact element made of insulating material for the connection known several stripped conductors, the connection end with a Cross bore is provided, into which the stripped conductors can be inserted. Here the connection end has a threaded bore into which one with a Tapered clamping screw is screwed on the stripped Head acts.

Aus der CH 448 204 ist daneben ein aus Isoliermaterial bestehender Steckerkörper bekannt, der ein als Kontaktbuchse ausgestaltetes Steckende aufweist. Auch hierbei ist eine Querbohrung vorgesehen, in die ein Litzenleiter einschiebbar ist, der mittels Klemmschrauben festgeklemmt und kontaktiert werden kann.CH 448 204 is also a connector body made of insulating material known, which has a plug end designed as a contact socket. Here too, a transverse bore is provided into which a stranded conductor can be inserted which is clamped and contacted by means of clamping screws can.

Aus der US 4 114 262 ist weiterhin ein Kabelverbinder bekannt, der einen Grundkörper mit einer Querbohrung für die Aufnahme eines Leiters aufweist. In die Querbohrung ist ein stiftförmiges Kontaktteil eindrückbar, welches eine Kontaktierung durch Druck auf den Leiter bewirkt.From US 4 114 262 a cable connector is also known, the one Has base body with a transverse bore for receiving a conductor. In the transverse bore is a pin-shaped contact part which can be pressed in Contacting caused by pressure on the conductor.

Aus der US 3 963 322 und der DE 296 06 881 U1 ist es allgemein bekannt, Klemmschrauben, die zur Klemmung und Kontaktierung eines Leiters verwendet werden, mit einer Kegelspitze zu versehen, die in den anzuschließenden Leiter eindringt.From US 3 963 322 and DE 296 06 881 U1 it is generally known Clamping screws used to clamp and contact a conductor are to be provided with a conical tip, which in the to be connected Head penetrates.

Der Erfindung liegt die Aufgabe zugrunde, ein Kontaktelement der eingangs genannten Art dahingehend auszubilden, daß dieses einfach herstellbar ist und der Anschluß der Leiter ohne spezielle Werkzeuge möglich ist, wobei der Platzbedarf der Kontaktelemente möglichst gering sein soll. The invention has for its object a contact element of the beginning mentioned type in that this is easy to manufacture and the connection of the conductors is possible without special tools, the Space requirement of the contact elements should be as small as possible.

Diese Aufgabe wird dadurch gelöst, daß das Kontaktelement aus einem einstückigen, zylindrischen Grundkörper aus elektrisch leitfähigem Material besteht, dessen eines Ende als Steckende und dessen anderes Ende als Leiteranschlußende ausgebildet ist, daß die Querbohrung im Leiteranschlußende vorgesehen ist, und als Stufenbohrung ausgebildet ist, wobei die Leitereinführseite der Bohrung den geringeren Durchmesser aufweist, daß die Gewindebohrung, axial im Grundkörper verlaufend, vom Steckende ausgeht, und daß die Klemmschraube durch das Steckende hindurch betätigbar ist.This object is achieved in that the contact element from one one-piece, cylindrical body made of electrically conductive material consists of one end as a plug end and the other end as Conductor connection end is formed such that the transverse bore in the conductor connection end is provided, and is designed as a stepped bore, the Conductor insertion side of the hole has the smaller diameter that the threaded hole, running axially in the base body, starts from the plug end, and that the clamping screw can be actuated through the plug end is.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 4 angegeben.Advantageous embodiments of the invention are specified in claims 2 to 4.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Litzenleiter ohne zusätzliche Hilfsmittel wie Kabelschuhe oder Aderendhülsen direkt nach dem Abisolieren auf eine Bestimmte Länge ohne aufwendige und teuere Werkzeuge nur mit einem Sechskantschlüssel entsprechender Größe angeklemmt werden können. Die Abmessungen des Klemmenbereiches überschreiten an keiner Stelle die Außenabmessungen des Hochstromkontaktes. Der Platzbedarf ist dabei minimal. Der Kontakt läßt sich gut in einem Isolierkörper einbetten, der nur je eine Öffnung für den Leiteranschluß und den Steckbereich benötigt. Die Klemme kann jederzeit von außen betätigt werden. Ein Überprüfen der Klemmkraft und, falls notwendig, Nachziehen der Klemmschraube im eingebauten Zustand ist möglich.
Durch die kegelförmige Spitze der Klemmschraube wird der Leiter allseitig gegen die Innenwand der Querbohrung gepreßt, ohne den Leiter zu beschädigen, wobei nur der Bereich der Bohrungsöffnung der Klemmschraube ausgespart bleibt. Es entsteht eine innige und gasdichte Verbindung. Die erreichbaren Leiterauszugskräfte sind sehr hoch und können mit denen von Crimpverbindungen verglichen werden. Die Verbindung ist wieder lösbar. Da der Leiter direkt angeklemmt wird, ist auch der Durchgangswiderstand gering und die Eigenerwärmung der Klemme ist dadurch ebenfalls sehr gering. Die Gefahr einer Fehlfunktion wird dadurch so gut wie ausgeschlossen. The advantages achieved with the invention consist in particular in that the stranded conductors can be clamped to a certain length without additional and expensive tools only with a hexagon key of the appropriate size without additional aids such as cable lugs or wire end sleeves. The dimensions of the terminal area never exceed the external dimensions of the high-current contact. The space requirement is minimal. The contact can be easily embedded in an insulating body, which only needs one opening for the conductor connection and the plug-in area. The clamp can be operated from outside at any time. It is possible to check the clamping force and, if necessary, retighten the clamping screw when installed.
Due to the conical tip of the clamping screw, the conductor is pressed on all sides against the inner wall of the transverse bore without damaging the conductor, only the area of the bore opening of the clamping screw being left out. An intimate and gas-tight connection is created. The conductor pull-out forces that can be achieved are very high and can be compared with those of crimp connections. The connection can be released again. Since the conductor is directly connected, the volume resistance is low and the self-heating of the terminal is also very low. This virtually eliminates the risk of malfunction.

Fig. 1
a contact element in section,
Fig. 2
the contact element with a connected conductor, and
Fig. 3
a perspective view of the contact element acc. Fig. 2 with an operating tool.

In den Fig. 1 bis 3 ist ein als Buchsenkontakt ausgebildetes Kontaktelement dargestellt, das im wesentlichen aus einem zylindrischen Grundkörper 1 mit einem Steckende 2 und einem Leiteranschlußende 3 besteht. Dabei kann das hier als Kontaktbuchse ausgebildete Steckende ggf. auch als Kontaktstift ausgebildet sein.1 to 3 is a contact element designed as a socket contact shown, which consists essentially of a cylindrical base body 1 there is a plug end 2 and a conductor connection end 3. It can here designed as a contact socket plug end optionally also formed as a contact pin be.

Das Leiteranschlußende ist mit einer dieses durchsetzenden Querbohrung 4 versehen. In diese Bohrung wird der anzuschließende Litzenleiter 5 (siehe. Fig. 2 und 3) eingeschoben. Dabei ist die Querbohrung als Stufenbohrung ausgeführt, wobei die Bohrung auf der Leitereinführseite 6 einen geringeren Durchmesser aufweist.The conductor connection end is with a transverse bore 4 passing through it Mistake. The stranded wire 5 to be connected (see. Fig. 2 and 3) inserted. The cross hole is designed as a stepped hole, the bore on the conductor insertion side 6 having a smaller diameter having.

Dadurch ist innerhalb der Querbohrung ein Absatz 7 ausgebildet, dessen Wirkung weiter unten beschrieben ist. Schließlich ist die Querbohrung auf der Leitereinführseite noch mit einer Fase 8 versehen, die das Einführen eines Leiters erleichtert.As a result, a shoulder 7 is formed within the transverse bore, its effect is described below. Finally, the cross hole is on the Conductor insertion side is also provided with a chamfer 8, which allows the insertion of a Leader relieved.

Ausgehend vom Steckende 2 des Kontaktelements ist der Grundkörper 1 mit einer axialen, zentrischen Gewindebohrung 9 versehen, die bis in die Querbohrung reicht und hier endet.
In diese Gewindebohrung ist eine Klemmschraube 10 eingeschraubt. Die Klemmschraube ist mit einer Kegelspitze 11 versehen, die in den in die Querbohrung eingeführten Litzenleiter gepreßt wird. Dabei ist das vordere Ende der Klemmschraube vorzugsweise mit einem abgesetzten, gewindelosen Schaft 12 versehen um eine Beschädigung der Litzen des Leiters beim Einschrauben der Klemmschraube durch scharfkantige Gewindegänge zu vermeiden.Starting from the plug end 2 of the contact element, the base body 1 is provided with an axial, central threaded bore 9 which extends into the transverse bore and ends here.
A clamping screw 10 is screwed into this threaded bore. The clamping screw is provided with a conical tip 11 which is pressed into the stranded conductor inserted into the transverse bore. The front end of the clamping screw is preferably provided with a stepped, unthreaded shaft 12 in order to avoid damage to the strands of the conductor when the clamping screw is screwed in due to sharp-edged threads.

Die Kegelspitze und die Querbohrung sind so aufeinander abgestimmt, daß mindestens zwei

Figure 00050001
benachbarte" Leiterquerschnitte angeklemmt werden können (z. B. 50 mm2 und 70 mm2 bzw. 95 mm2 und 120 mm2).
Zur Betätigung der Klemmschraube ist diese vorzugsweise mit einem Innensechskant 13 versehen und somit mittels eines Betätigungswerkzeuges 14 einschraubbar.The cone tip and the transverse bore are matched to one another so that at least two
Figure 00050001
adjacent "conductor cross sections can be clamped (e.g. 50 mm 2 and 70 mm 2 or 95 mm 2 and 120 mm 2 ).
To actuate the clamping screw, it is preferably provided with a hexagon socket 13 and can thus be screwed in by means of an actuating tool 14.

Zum Anschluß eines Litzenleiters 5 an das Kontaktelement wird dieser zunächst an seinem vorderen Ende von der Isolation befreit und dieses Ende in die Querbohrung eingeschoben.To connect a stranded conductor 5 to the contact element, this is first at the front end of the insulation and this end in inserted the cross hole.

Es können natürlich auch mehrere kleine Leiter gleichzeitig angeklemmt werden. Der Gesamtquerschnitt muß nur im vorgesehenen Klemmbereich liegen. Die Spitze der Klemmschraube 10 darf im Ausgangszustand noch nicht in die Querbohrung 4 hineinragen. Der abisolierte Litzenleiter 5 wird bis zum gegenüberliegenden Ende in die Querbohrung eingeschoben. Mit einem handelsüblichen Sechskantschraubendreher, dessen Ende durch die Längsbohrung im Kontaktelement bis in den Innensechskant der Klemmschraube geschoben wird, kann diese angezogen werden. Dabei taucht die Kegelspitze 11 in den Litzenleiter 5 ein und verteilt diesen gleichmäßig auf beide Seiten des sich verengenden Bohrungsquerschnittes. Im Bereich des Bohrungsabsatzes wird die Litze gegen die Wandung gepreßt. Da die Litze hinter dem Absatz 7 eine etwas größere Bohrung vorfindet, wird sie dort etwas stärker aufgeweitet. Diese Maßnahme bewirkt, daß ein Herausziehen des Leiters erschwert wird. Dazu sind große Auszugskräfte erforderlich, die mit denen einer Crimpverbindung vergleichbar sind. Bei Verwendung von Feingewinde wird gleichzeitig die Vibrationssicherheit erhöht. Da der Litzenleiter allseitig sowohl am äußeren Umfang als auch im Innenbereich durch den Klemmkegel kontaktiert wird, wird ein geringer Übergangswiderstand an der Anschlußstelle erzielt. Daher tritt an der Anschlußstelle auch nur eine geringe Eigenerwärmung auf.Of course, several small conductors can also be connected at the same time. The total cross section only has to be in the intended clamping area. The tip of the clamping screw 10 may not yet in the initial state Project cross hole 4. The stripped wire conductor 5 is to the opposite Inserted end into the cross hole. With a commercially available Hex screwdriver, the end of which through the longitudinal hole in the Contact element pushed into the hexagon socket of the clamping screw can be tightened. The cone tip 11 dips into the Stranded wire 5 and distributes it evenly on both sides of the narrowing Bore cross section. In the area of the bore heel Braid pressed against the wall. Since the strand behind the paragraph 7 a little finds larger hole, it is expanded a little more there. This measure causes it to be difficult to pull out the conductor. To do this large pull-out forces required, comparable to those of a crimp connection are. When using fine threads, the vibration security is simultaneously elevated. Since the stranded wire on all sides, both on the outer circumference as well as being contacted internally by the clamping cone, the Contact resistance achieved at the connection point. Therefore occurs at the Connection point only a small amount of self-heating.
