Der in den Fig. 4,5 und 6 dargestellte Transformatorkern ist dem vorbeschriebenen gleich. Das Gehäuse oder der Montierungsträger unterscheidet sich jedoch insoferne, als er aus zwei   rinnenförmigen   oder hohlen Teilen 34 besteht, die die Seiten des Kernes umfassen. Die Hohlteile 34 besitzen einwärtsragende Endflanschen 36 und 38 und an jedem Innenrand zwei Augen 40. Durch letztere dringen Bolzen 42, die dazu dienen, die Hohlteile gegeneinander zu ziehen und einen Druck auf die   Stossflächen   der Kernteile auszuüben. Die Bolzen 42 bezwecken auch die vorteilhaft aus Isoliermaterial hergestellten Klemmen-   platten 44 in Stellung zuhalten. Auf   den Klemmenplatten oder Streifen44sind Klemmenstücke 46 angebracht, von denen eines in Fig. 7 dargestellt ist.

   Eine durch die Öffnung 50 dringende Öse 48 sichert das betreffende 
 EMI2.1 
 Schlitz 53 dringt, und mit abgebogenen Endfortsätzen 54 und 55 versehen, die an die elektrische Leiter angelötet werden können. 



   Ein Schild 56 aus Aluminium od. dgl. kann zwischen den Flanschen 36 und dem Kern in Stellung gesichert werden. 



   Am Unterende der Hohlteile 34 sind   auswärtsgeriehtete   Flanschen 58 vorgesehen, um den Transformator auf einem Träger befestigen zu können. Zwischen dem Kern und seinem Gehäuse oder Träger kann, wenn erwünscht, ein geeignetes Futter eingelegt werden. 



   PATENT-ANSPRUCHE :
1. Magnetspule, dadurch gekennzeichnet, dass sie aus einer Anzahl von Kernabschnitten, die wesentlich ebene   Stossflächen   besitzen und aus einem Gehäuse besteht, dass diese Abschnitte umfasst und eine Einrichtung besitzt, mittels deren diese   Stossflächen   aneinandergedrückt werden.

The transformer core shown in FIGS. 4, 5 and 6 is the same as that described above. However, the housing or mounting bracket differs in that it consists of two trough-shaped or hollow parts 34 which encircle the sides of the core. The hollow parts 34 have inwardly projecting end flanges 36 and 38 and two eyes 40 on each inner edge. Bolts 42 penetrate through the latter and serve to pull the hollow parts against one another and exert pressure on the abutment surfaces of the core parts. The purpose of the bolts 42 is also to hold the terminal plates 44, which are advantageously made of insulating material, in position. Terminal pieces 46, one of which is shown in FIG. 7, are mounted on the terminal boards or strips 44.

   An eyelet 48 penetrating through the opening 50 secures the relevant one
 EMI2.1
 Slit 53 penetrates, and provided with bent end extensions 54 and 55, which can be soldered to the electrical conductor.



   An aluminum shield 56 or the like can be secured in place between the flanges 36 and the core.



   Outwardly directed flanges 58 are provided at the lower end of the hollow parts 34 in order to be able to fasten the transformer on a carrier. A suitable lining can be inserted between the core and its housing or carrier, if desired.



   PATENT CLAIMS:
1. Magnetic coil, characterized in that it consists of a number of core sections which have substantially flat abutment surfaces and consists of a housing that comprises these sections and has a device by means of which these abutment surfaces are pressed against one another.

Claims

2. Magnetic coil according to claim l, characterized in that one of the core sections is E-shaped, the other is L-shaped.

3. Magnetic coil according to claim 1 or 2, characterized in that the housing consists of channel-shaped or hollow parts which are drawn against one another by any means, for example by means of bolts.

4. Magnet coil according to claim 3, characterized in that the trough-shaped housing parts are provided with eyes through which the tightening bolts penetrate.

5. Magnetic coil according to claim 2, with a winding on the central arm of the E-shaped core section, characterized in that the core housing is designed in the form of a frame which includes all parts of the core with the exception of the central arm of the E-shaped core section.

6. Magnetic coil according to claim 3, 4 or 5, characterized in that a plate of the winding held by the housing lies adjacent in a plane which is perpendicular to that of the core, with clamps being mounted on this plate.

7. Magnetic coil according to claim 6, characterized in that the plate or the strip (44) consists of insulating material.

8. Magnetic coil according to claim 1 to 7, characterized in that a device is provided which is used to change the reluctance of the core and consists of an adjustable device which presses the abutment surfaces of the core sections together.

9. Solenoid with a terminal arrangement, characterized by a terminal plate (44) with at least one opening (50) and a slot (53), in which slot a projection (52) of a terminal piece (46) engages with bent parts for attaching the Conductor is provided, with an eyelet (48) penetrating through the terminal piece and the opening (50).
