KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es sind Verfahren zur Herstellung von Elektromagnetsystemen bekannt, bei denen aus geeignetem Blech ein hufeisenförmiger Magnet herausgestanzt und die Schenkel des Magneten zum Anziehen eines Ankers, das die Schenkel verbindende Joch zur Aufnahme einer Erregerwicklung benutzt wird. Diese Anordnung hat den Nachteil unvorteilhafter Raumausnutzung, da die Wicklung einseitigThere are known methods for the production of electromagnetic systems in which a horseshoe-shaped magnet is punched out of suitable sheet metal and the legs of the Magnets for attracting an anchor, the yoke connecting the legs for receiving an excitation winding is used. This arrangement has the disadvantage of being more unfavorable Utilization of space, as the winding is one-sided
ίο über das System hinausragt und Beschädigungen leicht ausgesetzt ist. Ein weiterer Nachteil besteht darin, daß der magnetische Kraftlinienschluß über die beiden Schenkel des Magneten und den Anker erfolgt.ίο protrudes beyond the system and damages is easily exposed. Another disadvantage is that the magnetic line of force closure over the two legs of the magnet and the armature takes place.
Die Erfindung bezweckt, diese Nachteile zu beseitigen und kennzeichnet sich im wesentlichen dadurch, daß aus einem entsprechend geformten Blech von geeignetem ferromagnetischen Material ein als Spulenkern dienendes Stück herausgestanzt und derart umgebogen wird, daß es zwischen den durch Umbiegen des Bleches gebildeten Schenkeln des Systems zu liegen kommt, so daß ein doppelter Kraftlinienschluß vorhanden und die Erregerwicklung durch die Schenkel des Systems geschützt ist.The invention aims to eliminate these disadvantages and is essentially characterized in that from a correspondingly shaped sheet of suitable ferromagnetic Material a piece serving as a coil core is punched out and bent over in such a way that it is between the by bending over of the plate formed legs of the system come to rest, so that a double power line closure present and the excitation winding is protected by the legs of the system is.
Eine einfache Ausführungsform ist· zur Erläuterung des Erfindungsgedankens beispielsweise auf der Zeichnung dargestellt. .Fig. 1 zeigt die ursprüngliche Form des Magnetsystems, während seine Verwendungsweise bei einer Signalklappe in Fig. 2 dargestellt ist. Die Bezugszeichen sind in beiden Figuren der Übersicht halber übereinstimmend gewählt worden, während die für die Erfindung belanglosen Einzelheiten fortgelassen sind. Das Magnetsystem besteht' aus ' einem Stanzstück rechteckigen Querschnittes (Fig. i), welches an den punktiert gezeichneten Linien rechtwinklig umgebogen wird, so daß zwei Schenkel b, c gebildet werden, welche durch das Joch a verbunden sind.A simple embodiment is shown, for example, on the drawing to explain the idea of the invention. .Fig. 1 shows the original form of the magnet system, while its use in a signal flap is shown in FIG. For the sake of clarity, the reference numbers have been chosen to be identical in both figures, while the details that are irrelevant to the invention have been omitted. The magnet system consists 'of' a stamped piece of rectangular cross-section (Fig. I), which is bent at right angles on the dotted lines, so that two legs b, c are formed, which are connected by the yoke a .
Aus einem der Schenkel, beispielsweise b, wird ein Teil d so herausgeschnitten; daß er nur noch auf einer Seite mit b vereinigt ist. Der Teil d wird darauf gleichfalls rechtwinklig umgebogen, und zwar derart, daß er zwischen den Schenkeln b, c zu liegen kommt und als Kern der Erregerwicklung w dient. Das äußere Ende des Schenkels b ist als Schneide s ausgebildet und wird als Stützfläche des Ankers e benutzt. Die Spule w, welche durch Isolierscheiben k begrenzt wird, füllt den durch die Schenkel des Systems gebildeten Zwischenraum aus, so daß die Raumausnutzung sehr günstig ist und die Schenkel gleichzeitig zum Schutz der Erregerwicklung dienen.Part d is cut out of one of the legs, for example b; that it is only united on one side with b. The part d is then also bent at right angles, in such a way that it comes to lie between the legs b, c and serves as the core of the excitation winding w . The outer end of the leg b is designed as a cutting edge s and is used as a support surface of the armature e . The coil w, which is delimited by insulating washers k , fills the space formed by the legs of the system, so that the space utilization is very favorable and the legs serve at the same time to protect the excitation winding.
