Description

Die Erfindung betrifft einen Spulenträger mit einer Aufnahme für einen Sicherheitsschalter.The invention relates to a coil carrier with a receptacle for a safety switch.

Bei elektrischen Spulen müssen Sicherheitsschalter, wie Wächter, zum Schutz gegen Überstrom und Übertemperatur vorgesehen sein. Diese werden bisher in der Regel in komplizierter und aufwen­diger Weise am Spulenträger der Spule vorgesehen. Ihr Halten ist nicht zuverlässig und die Kontaktierung der Kontaktelemente des Sicherheitsschalters mit der auf den Spulenträger aufzu­wickelnden Spule in der Regel aufwendig.With electrical coils, safety switches, such as guards, must be provided to protect against overcurrent and overtemperature. Up to now, these have generally been provided on the coil carrier of the coil in a complicated and complex manner. It is not reliable to hold it and the contacting of the contact elements of the safety switch with the coil to be wound onto the coil carrier is generally complex.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Spulen­träger der gattungsgemäßen Art zu schaffen, der einen zuver­lässigen Halt und eine zuverlässige Kontaktierung des Sicher­heitsschalters sowie einfache und bequeme Anschlußmöglichkeiten gewährleistet.The invention is therefore based on the object of providing a bobbin of the generic type which ensures reliable hold and reliable contacting of the safety switch and simple and convenient connection options.

Erfindungsgemäß wird die genannte Aufgabe bei einem Spulenträger der eingangs genannten Art gelöst durch ein elektrisch leiten­des Aufnahmeteil für den Sicherheitsschalter mit einer Aus­nehmung zur reibschlüssigen Aufnahme des Sicherheitsschalters. Der Sicherheitsschalter wird nicht mehr als solcher mit dem Spulenträger verbunden oder in diesen eingesetzt, sondern wird durch ein Aufnahme- oder Halteteil gehalten, welches gleich­zeitig über die den einen Kontakt des Schalters bildende Ge­häuseschale desselben die elektrische Kontaktierung sicher­stellt. Neben diesen Vorteilen kann durch die erfindungsgemäße Ausgestaltung der Schalter sicher und zuverlässig am Spulen­träger, insbesondere in einer Aufnahme desselben gehalten werden. Zur Verbesserung des Preß- oder Reibsitzes des Schalters im Aufnahmeteil sieht eine bevorzugte Ausgestaltung vor, daß das Aufnahmeteil plattenförmig ausgebildet ist und auf der Platten­ebene ein die Ausnehmung umgebender Flansch herausgebogen ist. Hierdurch wird eine flächige Anlage des leitenden Gehäuses an den Flanschen oder Laschen des Spulenträgers gewährleistet. Zur Erhöhung des Elastizität kann weiterhin vorgesehen sein, daß das Aufnahmeteil einen sich von der Ausnehmung zu einer Außenkante erstreckender Schlitz aufweist.According to the invention, the above-mentioned object is achieved in the case of a coil carrier of the type mentioned at the beginning by an electrically conductive receiving part for the safety switch with a recess for frictionally receiving the safety switch. The safety switch is no longer connected as such to the coil carrier or inserted into it, but is held by a receiving or holding part, which at the same time ensures the electrical contact via the housing shell forming a contact of the switch. In addition to these advantages, the design according to the invention allows the switch to be held securely and reliably on the coil carrier, in particular in a receptacle thereof. In order to improve the press or friction fit of the switch in the receiving part, a preferred embodiment provides that the receiving part is plate-shaped and a flange surrounding the recess is bent out on the plate level. This ensures a flat contact of the conductive housing on the flanges or tabs of the coil carrier. To increase the elasticity it can further be provided that the receiving part has a slot extending from the recess to an outer edge.

Eine Weiterbildung sieht vor, daß das Aufnahmteil im Randbe­reich aus seiner Ebene herausgestanzte Nasen aufweist. Hier­durch kann, insbesondere wenn das Aufnahmeteil in Nuten der Aufnahme des Spulenträgers geführt ist, eine sichere Festlegung des Sicherheitsschalters und damit eine Sicherung gegen Heraus­rutschen oder Herausziehen desselben gegeben werden.A further development provides that the receiving part has lugs punched out of its plane in the edge region. In this way, in particular if the receiving part is guided in grooves in the receiving means of the coil carrier, the safety switch can be securely fixed and thus secured against slipping out or being pulled out.

Eine weitere Ausbildung zur Vereinfachung und Verbesserung der Kontaktierung sieht vor, daß das Aufnahmeteil eine aus der Auf­nahme herausragende Anschlußlasche aufweist, wobei entweder die Anschlußlasche als Flachstecker oder aber eine Anschluß­lasche mit einem durch eine Unterschneidung gebildeten ver­jüngten Abschnitt ausgebildet ist.Another training to simplify and improve the contact provides that the receiving part has a protruding from the receptacle connection tab, either the connection tab is designed as a flat plug or a connection tab with a tapered portion formed by an undercut.

Der Erfindungsgedanke wird weiterhin dadurch unterstützt, daß die Aufnahme Längsnuten aufweist, in denen das Aufnahmeteil einsitzt, wodurch hier direkt beim Wickeln sogleich die Kon­taktierung der Wicklungsspule an dem Anschlußdraht des Schalters vorgenommen werden kann.The inventive concept is further supported by the fact that the receptacle has longitudinal grooves in which the receptacle is seated, so that the winding coil can be contacted directly on the connecting wire of the switch during winding.

Weiter Vorteile und Merkmale der Erfindung ergeben sich aus den Ansprüchen und aus der nachfolgenden Beschreibung, in der Ausführungsbeispiele der Erfindung unter Bezugnahme auf die Zeichnungen im einzelnen erläutert sind. Dabei zeigen:

  • Figur 1 Eine Sicht in Richtung der Spulenachse entsprechend I-I der Figur 2;
  • Figur 2 eine Sicht auf den Spulenträger entsprechend II-II der Figur 1, teilweise geschnitten; und
  • Figur 3 weitere Ausgestaltungen eines Aufnahmeteils für den Sicherheitsschalter.
Further advantages and features of the invention result from the claims and from the following description in which exemplary embodiments of the invention are explained in detail with reference to the drawings. Show:
  • 1 shows a view in the direction of the coil axis corresponding to II of Figure 2;
  • Figure 2 is a view of the coil carrier according to II-II of Figure 1, partially in section; and
  • Figure 3 further embodiments of a receiving part for the safety switch.

Der erfindungsgemäße Spulenträger 1 weist einen Trägerkern 2 und diesen begrenzende, parallel zueinander verlaufende Be­grenzungsplatten 3 auf, so daß auf den Trägerkern 2 in den Platten 3 eine Spulenwicklung aufgebracht werden kann. Seit­lich einer der Begrenzungsplatten 3 ist eine Aufnahme 4 für einen Sicherheitsschalter 6 ausgebildet. Bei dem Sicherheits­schalter 6 handelt es sich um einen Bimetall-Überstromschalter, wie einen Temperaturwächter.The coil carrier 1 according to the invention has a carrier core 2 and this delimiting, parallel to each other limiting plates 3, so that a coil winding can be applied to the carrier core 2 in the plates 3. A receptacle 4 for a safety switch 6 is formed on the side of one of the boundary plates 3. The safety switch 6 is a bimetal overcurrent switch, such as a temperature monitor.

Die Aufnahme 4 für den Schalter 6 ist als Tasche ausgebildet. Die Tasche wird im wesentlichen durch die Begrenzungswand 3, eine parallel zu dieser verlaufende Wand 7 und senkrecht zu diesen stehende Längsseitenwände 8 begrenzt. Die Aufnahme 4 weist eine Einschuböffnung 9 zum Einschieben des Schalters 6 und der Einschuböffnung 9 gegenüberliegend einen Durchbruch 11 in der Rückwand der Aufnahme 4 auf, durch welchen ein An­schlußdraht 12 aus der Aufnahme 4 heraus und durch einen Schlitz 13 in den Wicklungsbereich 14 der Spulenwicklung geführt werden kann.The receptacle 4 for the switch 6 is designed as a pocket. The pocket is essentially delimited by the boundary wall 3, a wall 7 running parallel to this and longitudinal side walls 8 perpendicular to these. The receptacle 4 has an insertion opening 9 for inserting the switch 6 and the insertion opening 9 opposite an opening 11 in the rear wall of the receptacle 4, through which a connecting wire 12 out of the receptacle 4 and through a slot 13 can be guided into the winding area 14 of the coil winding.

In den seitlichen Längswänden 8 sind, nahe der Begrenzungs­wand 3 Längsnuten 16 ausgebildet. Entlang dieser Längsnuten 16 kann ein Aufnahmeteil 17 zur Aufnahme und Halterung des Schalters 6 in die Aufnahme 9 des Spulenträgers 1 eingeschoben werden. Das Aufnahmeteil 17 weist eine der Breite der Aufnahme 9 unter Berücksichtigung der Nuten 16 entsprechende Breite und eine im wesentlichen der Aufnahme 9 entsprechende Länge auf. Über seine eigentliche, der Länge der Aufnahme 9 entsprechende Länge wird das Aufnahmeteil 17 durch eine Lasche 18 überragt, die als Flachstecker ausgebildet ist und auf der entsprechende Steckbuchsen zur Kontaktierung aufgesteckt werden können. Die Lasche 18 ragt aus der Öffnung 9 der Aufnahme 4 heraus.In the side longitudinal walls 8, 3 longitudinal grooves 16 are formed near the boundary wall. Along these longitudinal grooves 16, a receiving part 17 for receiving and holding the switch 6 can be inserted into the receptacle 9 of the coil carrier 1. The receiving part 17 has a width corresponding to the width of the receptacle 9, taking into account the grooves 16, and a length substantially corresponding to the receptacle 9. Over its actual length corresponding to the length of the receptacle 9, the receptacle part 17 is surmounted by a tab 18, which is designed as a flat plug and can be plugged onto the corresponding sockets for contacting. The tab 18 protrudes from the opening 9 of the receptacle 4.

Das Aufnahmeteil 17 weist einen kreisförmigen Durchbruch 19 auf. Der Durchbruch 19 wird durch einen aus der Ebene des flachen Aufnahmeteils 17 herausgebogenen Ringflansch 21 be­grenzt. Weiterhin weist das Aufnahmeteil zwischen der Ausnehmung 19 und seiner der Anschlußlasche 18 abgewandten Stirnseite 22 einen Schlitz 23 auf, der die Elastizität des Aufnahmeteils 17 im Bereich der Ausnehmung 19 unterstützt. In der Ausnehmung 19 sitzt reibschlüssig oder im Preßsitz der Schalter 6 ein, dessen einer Kontakt sein Gehäuse bildet, welches durch die getroffene Anordnung mit dem Aufnahmeteil 17 und damit mit der mit diesem einstückig ausgebildeten Lasche in elektrischer Ver­bindung steht. Zur sicheren Halterung des Aufnahmeteils 17 in der Aufnahme 4 und insbesondere den Nuten 16 sind aus der Ebene des Aufnahmeteils 17 heraus Nasen 26 geprägt, die ein Herausrutschen oder Herausziehen des Aufnahmeteils 17 aus der Aufnahme 4 verhindern.The receiving part 17 has a circular opening 19. The opening 19 is delimited by an annular flange 21 which is bent out of the plane of the flat receiving part 17. Furthermore, the receiving part between the recess 19 and its end face 22 facing away from the connecting lug 18 has a slot 23 which supports the elasticity of the receiving part 17 in the region of the recess 19. In the recess 19 sits frictionally or in the press fit of the switch 6, one contact of which forms its housing, which, through the arrangement made, is in electrical connection with the receiving part 17 and thus with the tab integrally formed therewith. In order to hold the receiving part 17 securely in the receptacle 4 and in particular the grooves 16, lugs 26 are embossed out of the plane of the receiving part 17 and prevent the receiving part 17 from slipping out or being pulled out of the receptacle 4.

Bei der Ausgestaltung der Figur 3 ist eine gegenüber der als Flachstecker ausgebildeten Anschlußlasche 18 andersartige An­schlußlasche 28 vorgesehen, die Hinterschneidungen 29 aufweist, so daß hier eine Kontaktierung, beispielsweise durch Herum­ wickeln eines Drahtstücks um den verjüngten Teil 31 der An­schlußlasche 28 vorgenommen werden kann. Zusätzlich kann auch, wie dies in Figur 3 gestrichelt dargestellt ist, die als Flach­stecker ausgebildete Anschlußlasche 18 vorgesehen sein. Gege­benenfalls kann eine der beiden Anschlußlaschen 18, 28, wenn sie nicht benötigt wird, abgeschnitten werden. Durch die er­findungsgemäße Ausgestaltung wird ein mit einem Sicherheits­schalter 6 versehener Spulenträger 1 geschaffen, der einfache und bequeme Anschlußmöglichkeiten bietet. Insbesondere ist im Gebrauch eine sichere Halterung und gleichzeitig zuverlässige Kontaktierung des Schalters 6 über das Aufnahmeteil 17 gegeben, welches zuverlässig und fest in der Aufnahme 4 gehalten wird und einen Anschlußkontakt zum Anschluß der elektrischen Strom­versorgung bildet, während der andere Kontakt des Schalters 6 über einen Anschlußdraht zum Wicklungsraum der Spule inner­halb des Spulenträgers 1 geführt wird, so daß die Spule dort leicht und bequem mit diesem verbunden werden kann, während ihr anderes Ende die Kontaktierung zur Stromversorgung bildet.In the embodiment of FIG. 3, a connection plate 28 of a different type from the connection plate 18, which is designed as a flat plug, is provided, which has undercuts 29, so that contact is made here, for example by moving around winding a piece of wire around the tapered part 31 of the connecting tab 28 can be made. In addition, as shown in dashed lines in FIG. 3, the connecting tab 18 designed as a flat plug can also be provided. If necessary, one of the two connecting lugs 18, 28 can be cut off if it is not required. The design according to the invention provides a coil carrier 1 which is provided with a safety switch 6 and which offers simple and convenient connection options. In particular, a secure mounting and at the same time reliable contacting of the switch 6 is provided via the receiving part 17, which is held reliably and firmly in the receptacle 4 and forms a connection contact for connecting the electrical power supply, while the other contact of the switch 6 via a connecting wire is guided to the winding space of the coil within the coil carrier 1, so that the coil can be easily and conveniently connected to it there, while its other end forms the contact to the power supply.
