Definitions
- the invention relates to an electromagnetic release for an electrical switching device, in particular for a circuit breaker or motor circuit breaker according to the preamble of claim 1.
- Electromagnetic triggers are generally designed as hinged armature or plunger armature triggers which have a magnet coil, a magnet core which is surrounded by the magnet coil, a magnet armature and a magnet yoke.
- the magnetic core is firmly connected to the magnetic yoke; if the magnet armature is designed as a plunger armature, a coil body is provided which surrounds the magnet armature and the magnet core and effects the guidance of the magnet armature.
- the solenoid is wound around the coil body, which is normally a single or multi-layer, cylindrical solenoid made of enamelled copper wire.
- the coil body between the magnet coil and the magnet core or the magnet armature is either made of insulating material or a non-ferrous metal, for example made of aluminum.
- the known magnetic triggers are relatively large.
- the object of the invention is to improve a magnetic release of the type mentioned, in particular to provide it with smaller dimensions.
- the magnet coil is accordingly formed by a wound copper foil, the inner turn of which - without the interposition of a coil former - is mechanically fixed and electrically conductively connected to the magnet core and guides the magnet armature. Since the magnetic core is attached to the magnetic yoke and the fixed contact piece of the electrical switching device is attached to the magnetic yoke, the inner turn is also conductively connected to the fixed contact piece. The turns following the inner turn are isolated from each other. On the outer turn, i.e. H. At the free end of the winding there is a conductor which, according to the invention, is connected or firmly connected to the end of the winding over the entire width and which leads to a terminal of the circuit breaker.
- the copper foil can also be provided on one side with a thin insulating layer, the position of the foil being so is chosen so that the bare side points towards the magnetic core and armature.
- a particularly space-saving design of the magnetic release can be achieved if the coil core and the armature and thus also the winding have a rectangular cross section.
- the magnetic release 10 has a closed magnetic yoke 11 (see FIG. 5), to the rear or right yoke web 12 of which is shown in FIGS. 1 and 5, a fixed contact piece 13 is fastened; Within the closed area of the magnetic yoke 11, on the web 12, a magnetic core 14 is fastened, which is only visible in broken lines in FIG. A winding 15, which surrounds the magnetic core 14 and is mechanically and electrically connected to it, is attached to the magnetic core 14.
- the inner turn 16 surrounds a tubular space 17 in which a magnet armature 18 is guided, a compression spring 19 being arranged between the magnet armature 18 and the magnet core 14.
- the coil 15 is made of copper foil, the side of the wound foil facing the magnet armature 18 or the magnetic core 14 being bare and the remote side being coated with insulating material.
- a connecting conductor 21 is fastened to the outer turn 20 and is connected to the end of the outer winding 20 over the entire width of the coil 15.
- FIG. 5 shows another view of the arrangement according to FIG. 1; the arrangement according to FIG. 3 is essentially the same; only the armature 30 and the core 31 shown in broken lines in FIG. 3 are different from the embodiment according to FIG. 1; the magnetic core 31 and the magnet armature 30 are rectangular, in the embodiment according to FIG. 3 the longer side edge of the cross-sectional shape runs parallel to the web 32, which corresponds to the web 12 and on which both the magnet armature 31 and the movable contact piece 13 (in FIG. 3 not shown) is connected.
- FIG. 4 shows a section through the magnetic core 31.
- a bare copper foil instead of a copper foil coated with insulation on one side; Insulating foils are introduced between the turns which adjoin the innermost turn 16, which is not shown. If one side of the copper foil is provided with an insulating layer, the position of the foil is chosen so that the bare side points in the direction of the magnetic core and armature.
- the use of a rectangular magnetic core and magnetic armature results in a particularly space-saving design of the magnetic release.
- the width B of the film corresponds approximately to the width of the magnetic release, the width B only being increased by the magnet yoke 11.
- the lead 21 is a solid conductor; it can also be a flexible conductor and it is connected to a connecting terminal. As a result, a current flows from the connection terminal to the conductor 21, with a thermal release possibly being switched on up to the outer turn 20, the inner turn 16 and from there via the magnetic core 14/31 to the fixed contact piece 13.

Description
Die Erfindung betrifft einen elektromagnetischen Auslöser für ein elektrisches Schaltgerät, insbesondere für einen Leitungsschutz- oder Motorschutzschalter gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electromagnetic release for an electrical switching device, in particular for a circuit breaker or motor circuit breaker according to the preamble of claim 1.
Elektromagnetische Auslöser sind im allgemeinen als Klappanker- oder Tauchankerauslöser ausgebildet, die eine Magnetspule, einen Magnetkern, der von der Magnetspule umgeben ist, einen Magnetanker und ein Magnetjoch aufweisen. Der Magnetkern ist mit dem Magnetjoch fest verbunden; wenn der Magnetanker als Tauchanker ausgebildet ist, ist ein Spulenkörper vorgesehen, der den Magnetanker und den Magnetkern umgibt und die Führung des Magnetankers bewirkt. Um den Spulenkörper ist die Magnetspule gewikkelt, die im Normalfall eine ein- oder mehrlagige, zylindrische Magnetspule aus lackisoliertem Kupferdraht ist. Der Spulenkörper zwischen der Magnetspule und dem Magnetkern bzw. dem Magnetanker ist entweder aus Isolierstoff oder einem Nichteisenmetall, beispielsweise aus Aluminium.Electromagnetic triggers are generally designed as hinged armature or plunger armature triggers which have a magnet coil, a magnet core which is surrounded by the magnet coil, a magnet armature and a magnet yoke. The magnetic core is firmly connected to the magnetic yoke; if the magnet armature is designed as a plunger armature, a coil body is provided which surrounds the magnet armature and the magnet core and effects the guidance of the magnet armature. The solenoid is wound around the coil body, which is normally a single or multi-layer, cylindrical solenoid made of enamelled copper wire. The coil body between the magnet coil and the magnet core or the magnet armature is either made of insulating material or a non-ferrous metal, for example made of aluminum.
Aus der DE-OS 33 12 069 ist bekannt, die Spule aus spiralförmig aufgewickeltem blankem Flachbandmaterial herzustellen, das zur Isolierung mit isolierendem härtbarem Kunststoff allseitig umspritzt ist; die Mittelbohrung dient als Führung des Magnetankers.From DE-OS 33 12 069 it is known to produce the coil from spirally wound bare flat strip material, which is encapsulated on all sides for insulation with insulating hardenable plastic; the center hole serves as a guide for the magnet armature.
Aufgrund der Spulendrahtabmessung und ggf. dem durch das zusätzliche Spulenrohr oder Isolierkörper vergrößerten Spulendurchmesser sind die bekannten Magnetauslöser relativ groß.Because of the coil wire dimensions and possibly the coil diameter increased by the additional coil tube or insulating body, the known magnetic triggers are relatively large.
Aufgabe der Erfindung ist es, einen Magnetauslöser der eingangs genannten Art zu verbessern, insbesondere mit kleineren Abmessungen zu versehen.The object of the invention is to improve a magnetic release of the type mentioned, in particular to provide it with smaller dimensions.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.
Die Magnetspule ist demgemäß durch eine gewickelte Kupferfolie gebildet, deren innere Windung - ohne Zwischenfügung eines Spulenkörpers - mechanisch fest und elektrisch leitend mit dem Magnetkern verbunden ist und den Magnetanker führt. Da der Magnetkern am Magnetjoch befestigt ist und am Magnetjoch das Festkontaktstück des elektrischen Schaltgerätes angebracht ist, ist die innere Windung auch mit dem Festkontaktstück elektrisch leitend verbunden. Die an die innere Windung anschließenden Windungen sind voneinander isoliert. An der äußeren Windung, d. h. am freien Ende der Wicklung schließt ein Leiter an, der erfindungsgemäß über die gesamte Breite an dem Ende der Wicklung angeschlossen bzw. daran fest verbunden ist und der zu einer Anschlußklemme des Leitungsschutzschalters führt.The magnet coil is accordingly formed by a wound copper foil, the inner turn of which - without the interposition of a coil former - is mechanically fixed and electrically conductively connected to the magnet core and guides the magnet armature. Since the magnetic core is attached to the magnetic yoke and the fixed contact piece of the electrical switching device is attached to the magnetic yoke, the inner turn is also conductively connected to the fixed contact piece. The turns following the inner turn are isolated from each other. On the outer turn, i.e. H. At the free end of the winding there is a conductor which, according to the invention, is connected or firmly connected to the end of the winding over the entire width and which leads to a terminal of the circuit breaker.
Die Kupferfolie kann auch einseitig mit einer dünnen Isolierschicht versehen sein, wobei die Lage der Folie so gewählt wird, daß die blanke Seite in Richtung Magnetkern und -anker zeigt.The copper foil can also be provided on one side with a thin insulating layer, the position of the foil being so is chosen so that the bare side points towards the magnetic core and armature.
Eine besonders platzsparende Ausgestaltung des Magnetauslösers erreicht man dann, wenn der Spulenkern und der Anker und damit auch die Wicklung einen rechteckigen Querschnitt aufweisen.A particularly space-saving design of the magnetic release can be achieved if the coil core and the armature and thus also the winding have a rectangular cross section.
Unterschiedliche Nennstromstärken werden durch unterschiedliche Dicken der Kupferfolie und unterschiedliche Windungszahlen realisiert.Different nominal current strengths are realized through different thicknesses of the copper foil and different numbers of turns.
Anhand der Zeichnung, in der zwei Ausführungsbeispiele der Erfindung dargestellt sind, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung näher erläutert und beschrieben werden.On the basis of the drawing, in which two exemplary embodiments of the invention are shown, the invention and further advantageous refinements and improvements of the invention are to be explained and described in more detail.

Der Magnetauslöser 10 gemäß Figur 1 besitzt ein geschlossenes Magnetjoch 11 (siehe Figur 5) an dessen in der Figur 1 bzw. 5 dargestelltem hinterem bzw. rechtem Jochsteg 12 ein Festkontaktstück 13 befestigt ist; innerhalb des geschlossenen Bereiches des Magnetjoches 11, am Steg 12 ist ein Magnetkern 14 befestigt, der in Figur 1 lediglich gestrichelt sichtbar ist. Am Magnetkern 14 befestigt ist eine Wicklung 15, die den Magnetkern 14 umgibt und mechanisch und elektrisch mit diesem verbunden ist. Die innere Windung 16 umgibt einen rohrförmigen Raum 17, in dem ein Magnetanker 18 geführt ist, wobei zwischen dem Magnetanker 18 und dem Magnetkern 14 eine Druckfeder 19 angeordnet ist. Die Spule 15 ist aus Kupferfolie hergestellt, wobei die dem Magnetanker 18 bzw. dem Magnetkern 14 zugewandte Seite der gewickelten Folie blank und die abgelegene Seite mit Isoliermaterial beschichtet ist. An der äußeren Windung 20 ist ein Anschlußleiter 21 befestigt, der über die gesamte Breite der Spule 15 mit dem Ende der äußeren Wicklung 20 verbunden ist.The
Die Figur 5 zeigt eine andere Ansicht der Anordnung gemäß Figur 1; die Anordnung gemäß Figur 3 ist im wesentlichen gleich; lediglich der Anker 30 und der strichliert in der Figur 3 sichtbare Kern 31 sind gegenüber der Ausführungsform nach Figur 1 unterschiedlich; der Magnetkern 31 und der Magnetanker 30 sind rechteckförmig, wobei bei der Ausführung nach Figur 3 die längere Seitenkante der Querschnittsform parallel zum Steg 32 verläuft, der dem Steg 12 entspricht und an dem sowohl der Magnetanker 31 als auch das bewegliche Kontaktstück 13 (in Figur 3 nicht dargestellt) angeschlossen ist.FIG. 5 shows another view of the arrangement according to FIG. 1; the arrangement according to FIG. 3 is essentially the same; only the
Man erkennt den gleichartigen Aufbau aus Figur 4, die einen Schnitt durch den Magnetkern 31 zeigt.One can see the similar structure from FIG. 4, which shows a section through the
Damit klar ersichtlich ist, daß das Magnetankersystem gemäß den Figuren 1 und 3 im wesentlichen identisch ist, sind bei der Ausführung nach Figur 5 die gemeinsamen sowie die unterschiedlichen Bezugsziffern eingetragen.So that it can be clearly seen that the magnet armature system according to FIGS. 1 and 3 is essentially identical, the common and the different reference numbers are entered in the embodiment according to FIG.
Es besteht natürlich auch die Möglichkeit, anstatt einer einseitig mit einer Isolierung beschichteten Kupferfolie eine blanke Kupferfolie zu verwenden; zwischen den Windungen, die sich an die innerste Windung 16 anschließen, sind - was nicht dargestellt ist - Isolierfolien eingebracht. Wenn eine Seite der Kupferfolie mit einer Isolierschicht versehen ist, wird die Lage der Folie so gewählt, daß die blanke Seite in Richtung Magnetkern und - anker zeigt. Die Verwendung eines rechteckigen Magnetkerns und Magnetankers bewirkt eine besonders platzsparende Ausgestaltung des Magnetauslösers.It is of course also possible to use a bare copper foil instead of a copper foil coated with insulation on one side; Insulating foils are introduced between the turns which adjoin the
Man erkennt auch aus der Figur 5, daß die Breite B der Folie etwa der Breite des Magnetauslösers entspricht, wobei die Breite B lediglich durch das Magnetjoch 11 vergrößert wird.It can also be seen from FIG. 5 that the width B of the film corresponds approximately to the width of the magnetic release, the width B only being increased by the
Der Anschlußleiter 21 ist ein massiver Leiter; er kann auch ein flexibler Leiter sein und er ist mit einer Anschlußklemme verbunden. Dadurch fließt ein Strom von der Anschlußklemme zum Leiter 21 wobei ggf. noch ein thermischer Auslöser eingeschaltet ist, bis hin zu der äußeren Windung 20, zur inneren Windung 16 und von dort über den Magnetkern 14/31 zum Festkontaktstück 13.The
