Description
Spule, insbesondere für elektromagnetische Materialprüfeinrichtungen. Die Erfindung bezieht sich auf Spulen., insbesondere fürelektromagnetische Materialprüfeinrichtungen. Es ist bekannt, derartige Spulen teilbar auszugestalten, um den zu priifend,en Körper seitwärts in die Spule einschieben. zu könnten: Die Herstellung der Verbindungen der einzelnen Windungen ist jedoch schwierig durchzuführen, außerdem besteht die Gefahr, daß ein einziger schlechter Kontakt den Widerstand der Spule so stark verändert, daß eine etwa mit der Spule vorgenommene Messung völlig falsche Ergebnisse liefert.Coil, in particular for electromagnetic material testing devices. The invention relates to coils, particularly for electromagnetic material testing equipment. It is known to make such coils divisible in order to be able to test the body slide it sideways into the bobbin. to could: Making the connections However, the individual turns is difficult to carry out, and there is also the Danger that a single bad contact changes the resistance of the coil so much that that a measurement made with the coil, for example, gives completely wrong results.
Die Aufgabe der Erfindung ist es nun, diesen Übelstand zu beseitigen. Dies wird dadurch erreicht, daß die Spule aus einzelnen Lamellen besteht, die an den Öffnungsstellen scharni-erartig ineinander übergreifen. Hierdurch werden außerordentlich sicher wirkende und leicht zu bedienende große Kontaktflächen gewonnen, außerdem erhält die Spule eine große Festigkeit und kann ohne Wicklungsunterlage ausgeführt werden.The object of the invention is now to eliminate this drawback. This is achieved in that the coil consists of individual lamellae that are attached to the opening points overlap one another like a hinge. This will make them extraordinary safe-looking and easy-to-use large contact surfaces won, In addition, the coil is given great strength and can be used without a winding support are executed.
Durch das an sich bekannte Mittel der Transformierung der Meßströme kann erreicht werden, daß die Spulen aus nur einer oder verhältnismäßig wenigen Windungen bestehen, und es wird weiterhin eine besondere Ausgestaltung der Transformation in Verbindung mit den neuen Spulen beschrieben.By means of transforming the measuring currents, which is known per se can be achieved that the coils from only one or relatively few Windings exist, and there will continue to be a special design of the transformation in connection with the new coils.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An exemplary embodiment is shown in the drawing.
In der Abb. i ist i ein Drahtseil, das geprüft werden soll. 2 ist die Spule, die in dieser Darstellung nur noch eine in sich geschlossene Windung erkennen läßt. 3 ist ein ringförmiger Eisenkern, der, um die Form der Spule besser zu zeigen, in der Mitte durchgeschnitten. ist. q. ist eine fest auf den Eisenkern aufgewickelte Spule von beliebiger Windungszahl und normaler Ausführung.In Fig. I, i is a wire rope to be tested. 2 is the coil, which in this illustration only has one self-contained turn reveals. 3 is a ring-shaped iron core, which to make the shape of the coil better to show cut in the middle. is. q. is one firmly on the iron core wound coil of any number of turns and normal design.
In der Abb.2 ist die eine Hälfte der aufklappbaren Spule 2 von innen her gesehen dargestellt.In Fig.2, one half of the foldable coil 2 is from the inside seen from here.
Zur Herstellung größerer Kontaktflächen sind beide Hälften durch ein vielfach geblättertes Scharnier 5 miteinander verbunden, das durch einen Bolzen 6 geführt wird, und dessen einzelne Lamellen durch die Mutter 7 fest aufelnandergepreßt werden können. Auf der anderen Seite sind die Wicklungsh,älfben abwechselnd mit Einschnitten 8 und lam@ellenartitgen Ansätzen 9 versehen, die beim Zusammenklappen der Spulen ineänandergreifen. In den Ansätzen 9 ist eine Aussparung i o zur Aufnahme eines Bolzens i i vorgesehen. Durch der. Bolzen. i i können die einzelnen Ansätze der beiden Windungshälften fest gegeneinandergepreßt werden.To produce larger contact surfaces, both halves are through one multiple leaf hinge 5 interconnected by a bolt 6 is performed, and the individual lamellae pressed together firmly by the nut 7 can be. On the other hand, the winding halves are alternating with Incisions 8 and lam @ ellenartitgen approaches 9 provided that when folded of the coils intermesh. In the approaches 9 is a recess i o for receiving a bolt i i provided. Through the. Bolt. i i can use the individual approaches of the two turn halves are pressed firmly against each other.
Wenn mehrere Windungen verwandt werden, kann man ebenso wie in dem Ausführungsbeispiel je zwei Windungshälften durch einen Scharnierbolzen 6 miteinander verbinden, jedoch müssen die einzelnen Windungen voneinander isoliert und deren Anschlußstellen so weit gegeneinander versetzt werden, daß sie in die danebenliegende Windung eingreifen. Die Verspannung der Scharnierlamellen und der Kontaktlamellen kann für alle Windungen gemeinsam durch zwei Bolzen 6 und i i erfolgen, doch müssen aber die Bolzen isoliert durch die einzelnen Windungen hindurchgeführt werden.If several turns are used, one can just as in that Exemplary embodiment, two turn halves each with one another by means of a hinge pin 6 connect, but the individual turns must be isolated from each other and their Connection points are offset against each other so far that they are in the adjacent Engage the turn. The bracing of the hinge lamellae and the contact lamellae can be done for all turns together by two bolts 6 and i i, but must but the bolts are passed through the individual turns in an isolated manner.
