Abstract

It is intended to create a primary connecting device, especially for current transformers, which provides a reliable electrical connection between the primary conductor, located inside the transformer, and the external current supply, with cost-effective production. This is achieved by means of a connecting device which consists of a threaded bush (1) having an internal thread (2) for holding a threaded bolt (7) which produces the external connection, and having an external thread (3) on which a nut (4) is seated which, in the tightened state, presses the primary conductor (5) tightly together with the one seating surface of a contact disc (6) which consists of electrically highly conductive material and is firmly connected, by shrinking or pressing onto the end of the threaded bush (1) holding the threaded bolt (7) to the threaded bush (1), and whose other seating surface forms the contact surface for the external current-conductor connection (8). <IMAGE>

Description

Primär-Anschlußvorrichtung, insbesonderePrimary connection device, in particular

für Stromwandler De Erfindung bezieht sich auf eine Primär-Anschlußvorr:.chtung nach dem Oberbegriff des Anspruchs 1.for current transformers The invention relates to a primary connection device according to the preamble of claim 1.

EE ist bekannt, Primär-Anschlußklemmen für Stromwandler ais massive Anschlußstücke aus Kupfer oder Messing herzustellen. Solche Anschlußstücke erfordern einen großen Materialaufwand und eine kostenaufwendige Herstellung durch zerspanende Formgebung.EE is known to have primary terminals for current transformers as massive Manufacture fittings from copper or brass. Require such fittings a large amount of material and an expensive production by machining Shaping.

Der Erfindung liegt die Aufgabe zugrunde, eine Primär-Anschlußvorrichtung zu schaffen, welche die Nachteile der bekannten Anschlußvorrichtungen vermeidet und bei kostengünstiger Herstellung eine zuverlässige elektrische Verbindung zwischen dem innerhalb eines Gerätes, insbesondie eines Wandlers, befindlichen Stromleiter mit der äußeren Stromzuführung ergibt.The invention is based on the object of a primary connection device to create which avoids the disadvantages of the known connection devices and a reliable electrical connection between the current conductor located within a device, especially a converter with the external power supply.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Merkmale gelöst.This object is achieved by the features characterized in claim 1 solved.

Vorteilhafte Weiterbildungen sind in den Unteransprüchen gekennzeichnet.Advantageous further developments are characterized in the subclaims.

Im folgenden wird die Erfindung an Hand eines Ausführungsbeispieles näher erläutert.In the following the invention is based on an exemplary embodiment explained in more detail.

Die in der einzigen Figur dargestellte Primär-Anschlußvorrichtung besteht aus einer Gewindebuchse 1 mit einem Innengewinde 2 zur Aufnahme eines den äußeren Anschluß herstellenden Gewindebolzens 7. Die Gewindebuchse 1 besitzt außerdem ein Außengewinde 3, auf dem eine Mutter 4 sitzt, die im angezogenen Zustand einen Pimärleiter 5 fest mit der einen Auflagefläche einer Kontaktscheibe 6 zusammenpreßt. Im gezeigten Ausführungsbeispiel ist der Primärleiter 5 aus einzelnen Bändern zusammengesetzt. Während die Gewindebuchse 1 vorzugsweise aus Stahl besteht, ist die Kontaktscheibe 6 aus einem elektrisch gut leitendem Material, vorzugsweise Kupfer, hergestellt. Die Kontaktscheibe 6 ist mit der Gewindebuchse 1 durch Aufschrumpfen oder Aufpressen auf die den Gewindebolzen 7 aufnehmende Stirnseite der Gewindebuchse fest verbunden. Zur Herstellung des elektrischen Anschlusses wird der äußere Stromleiter 8 durch den Gewindebolzen 7 an die andere Kontaktfläche der Kontaktscheibe 6 fest angepreßt. Die Gewindebuchse 1 kann Drehsicherungen beispielsweise in Form von Rändelungen aufweisen, die beim Verdrehen des äußeren Stromleiters 8 ein Lockern der Verbindung verhindern.The primary connection device shown in the single figure consists of a threaded bushing 1 with an internal thread 2 for receiving one of the external connection producing threaded bolt 7. The threaded bushing 1 also has an external thread 3 on which a nut 4 sitting in the dressed State a primary conductor 5 fixed to the one contact surface of a contact disk 6 compresses. In the exemplary embodiment shown, the primary conductor 5 is made up of individual elements Ribbons assembled. While the threaded bush 1 is preferably made of steel, the contact disk 6 is preferably made of a material with good electrical conductivity Copper, manufactured. The contact disk 6 is shrink-fitted to the threaded bushing 1 or pressing onto the end face of the threaded bushing that receives the threaded bolt 7 firmly connected. The external conductor is used to establish the electrical connection 8 by means of the threaded bolt 7 on the other contact surface of the contact disk 6 pressed on. The threaded bushing 1 can have anti-rotation locks, for example in the form of knurls have that when twisting the outer conductor 8 loosening of the connection impede.

Die erfindungsgemäße Anschlußvorrichtung ist kostengünstig herstellbar. Die Gewindebuchse 1 ermöglicht zuverlässig ein festes Anziehen des Gewindebolzens 7 zur Herstellung der Kontaktverbindung. Die Kontaktscheibe 6 aus elektrisch gut leitfähigem Material sorgt für eine gute Stromleitung. Durch die Verwendung von mehreren Anschlußbuchsen nach der Erfindung lassen sich den Erfordernissen gut angepaßte Kontaktstellen herstellen.The connecting device according to the invention can be produced inexpensively. The threaded bushing 1 reliably enables the threaded bolt to be tightened firmly 7 for establishing the contact connection. The contact disk 6 from electrically good Conductive material ensures good power conduction. By the use of several connection sockets according to the invention can be well adapted to the requirements Establish contact points.
