Abstract
Es soll eine Primär-Anschlußvorrichtung, insbesondere für Stromwandler, geschaffen werden, die bei kostengünstiger Herstellung eine zuverlässige elektrische Verbindung zwischen dem innerhalb des Wandlers befindlichen Primärleiter und der äußeren Stromzuführung ergibt. Erreicht wird dies durch eine Anschlußvorrichtung, die aus einer Gewindebuchse (1) mit einem Innengewinde (2) zur Aufnahme eines den äußeren Anschluß herstellenden Gewindebolzens (7) und einem Außengewinde (3) besteht, auf dem eine Mutter (4) sitzt, die im angezogenen Zustand, den Primärleiter (5) fest mit der einen Auflagefläche einer aus elektrisch gut leitfähigem Material bestehenden Kontaktscheibe (6) zusammenpreßt, die durch Aufschrumpfen oder Aufpressen auf die den Gewindebolzen (7) aufnehmende Stirnseite der Gewindebuchse (1) mit der Gewindebuchse (1) fest verbunden ist und deren andere Auflagefläche die Kontaktfläche für den äußeren Stromleiteranschluß (8) bildet.A primary connection device, in particular for current transformers, is to be created which, while being inexpensive to manufacture, results in a reliable electrical connection between the primary conductor located inside the converter and the external power supply. This is achieved by a connection device, which consists of a threaded bushing (1) with an internal thread (2) for receiving a threaded bolt (7) producing the external connection and an external thread (3) on which a nut (4) sits, which is inserted in tightened state, the primary conductor (5) firmly presses together with the one contact surface of a contact disk (6) made of electrically conductive material, which by shrinking or pressing onto the end face of the threaded bushing (1) receiving the threaded bolt (7) with the threaded bushing (1 ) is firmly connected and the other contact surface forms the contact surface for the external conductor connection (8).
Description
Hierzu 1 Blatt Zeichnungen1 sheet of drawings
Die Erfindung bezieht sich auf eine Primär-Anschlußeinrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a primary connection device according to the preamble of claim 1.
Es ist bekannt, Primär-Anschlußklemmen für Stromwandler als massive Anschlußstücke aus Kupfer oder Messing herzustellen. Solche Anschlußstücke erfordern einen großen Materialaufwand und eine kostenaufwendige Herstellung durch zerspanende Formgebung.It is known, primary terminals for current transformers to be produced as solid connection pieces made of 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-Anschlußeinrichtung zu schaffen, welche die Nachteile der bekannten Anschlußvorrichtungen vermeidet und bei kostengünstiger Herstellung eine zuverlässige elektrische Verbindung zwischen dem innerhalb eines Gerätes, insbesondere 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 one with inexpensive production electrical connection between that located within a device, in particular a converter Conductor with the external power supply results.
Diese Aufgabe wird durch die im Anspruch 1 gekenn- so zeichneten Merkmale gelöstThis object is achieved by the features identified in claim 1
Vorteilhafte Weiterbildungen sind in den Unteransprüchen gekennzeichnet.Advantageous further developments are in the subclaims marked.
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-Anschlußeinrichtung 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 Primärleiter 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 Kontakt-The primary connection device shown in the single figure consists of a threaded bushing 1 with an internal thread 2 for receiving a threaded bolt 7 producing the external connection Threaded bushing 1 also has an external thread 3 on which a nut 4 sits, which in the tightened state a primary conductor 5 firmly presses together with the one contact surface of a contact disk 6. Im shown In the exemplary embodiment, the primary conductor 5 is composed of individual strips. While the threaded bushing 1 is preferably made of steel, the contact washer 6 is made of a material with good electrical conductivity, preferably copper. The contact
