Description

Im Patent 877 208 ist ein Magnetkopf für Magnettongeräte beschrieben, dessen wesentliches Merkmal darin besteht, daß die Magnetpole auswechselbar sind. Die vorzugsweise zwei Magnetpole sind durch eine urimagnetische Schicht im Luftspalt miteinander verlötet und bestehen jeder aus einem glatten Draht, d. h. nicht lamelliertem Blech. Sie bilden gemäß dem Hauptpatent eine U-förmige Einheit, die in den Magnetkopfträger einsteckbar und mittels einer Klemmen-, Steck-oder Schraubverbindung auswechselbar anzuordnen ist.The patent 877 208 describes a magnetic head for magnetic sound recorders, the essential feature of which is that the magnetic poles are interchangeable. The preferably two magnetic poles are soldered to one another by a urimagnetic layer in the air gap and each consist of a smooth wire, ie non-laminated sheet metal. According to the main patent, they form a U-shaped unit which can be inserted into the magnetic head carrier and can be arranged to be exchangeable by means of a clamp, plug or screw connection.

Die Erfindung betrifft eine verbesserte Ausbildung der U-förmigen Gestalt dieses Bügels. Es hat sich durch Versuche herausgestellt, daß die in dem Ausführungsbeispiel des Hauptpatents gezeichnete Gestalt, die eine abgeflachte U-Form hat, kein genügendes homogenes Magnetfeld außerhalb des Spaltes erzeugt.The invention relates to an improved design of the U-shaped Shape of this bracket. Experiments have shown that the Embodiment of the main patent drawn shape that has a flattened U-shape has not generated a sufficient homogeneous magnetic field outside the gap.

Gemäß der Erfindung ist die Gestalt des U-förmigen Bauteils derart beschaffen, daß keine Knickstellen in dem Bügel auftreten und vorzugsweise ein kegelschnittförmiger, gegebenenfalls möglichst genau halbkreisförmiger Verlauf der U-Form vorhanden ist. Durch diese Formgebung wird ein möglichst gleichmäßiger Austritt der magnetischen Kraftlinien aus der Oberfläche der Polstücke außerhalb des Luftspaltes in den Magnettonträger erreicht.According to the invention, the shape of the U-shaped member is such designed so that no kinks occur in the bracket and preferably a conic section, if necessary, a semicircular course of the U-shape is present as precisely as possible. This shape ensures that the magnetic exit is as uniform as possible Lines of force from the surface of the pole pieces outside the air gap in the magnetic sound carrier achieved.

In der Zeichnung ist eine Ausführungsform der Einrichtung nach der Erfindung beispielsweise dargestellt. In der Figur ist ein Bügel dargestellt, der aus zwei Polschuhen i und ä besteht, die in zwei Wicklungen 3 und q. einsteckbar sind und unten durch ein magnetisches Zwischenstück 5 miteinander verbunden werden. Erfindungsgemäß ist die Form des Bügels symmetrisch zum Luftspalt 6 halbkreisförmig. Der Luftspalt 6 selbst ist durch ein nichtmagnetisches Material verlötet, so daß eine bauliche Einheit der Teile z und 2 entsteht. Der Magnettonträger 7, der bandförmig gedacht ist, bewegt sich unmittelbar vor dem Spalt 6 vorbei.In the drawing is an embodiment of the device according to Invention shown for example. In the figure, a bracket is shown that consists of two pole pieces i and ä, which are in two windings 3 and q. insertable and are connected to one another at the bottom by a magnetic intermediate piece 5. According to the invention, the shape of the bracket is semicircular symmetrically to the air gap 6. The air gap 6 itself is soldered by a non-magnetic material, so that a structural unit of parts z and 2 is created. The magnetic sound carrier 7, the band-shaped is intended, moves immediately in front of the gap 6 over.

Das Ausführungsbeispiel ist unter Umständen auch in der Weise abzuwandeln, daß ein mehrpoliger Magnetkopf vorhanden ist, indem beispielsweise symmetrisch in der Mitte der Bügel i und 2 noch eine weitere Lamelle vorhanden ist, die den Luftspalt teilt, so daß der Köpf in an sich bekannter Weise gleichzeitig zum Löschen und Rufsprechen od. dgl. benutzt werden kann.Under certain circumstances, the exemplary embodiment can also be modified in such a way that that a multi-pole magnetic head is present by, for example, symmetrically in In the middle of the bracket i and 2 there is another lamella which forms the air gap shares so that the head in a manner known per se for deleting and speaking at the same time or the like. Can be used.
