Description

1 Spule für ein elektromagnetisches Relais 5 * Die Erfindung betrifft eine Spule für ein elektromagnetisches Relais mit einem Spulenkörper, der ein in seiner Grundform zy¬ lindrisches Spulenrohr als Träger für ein Wicklungspaket sowie zwei Flansche als jeweilige axiale Begrenzungen des Wickelrau- 10 es bildet.1 coil for an electromagnetic relay 5 * The invention relates to a coil for an electromagnetic relay with a coil body which forms a cylindrical coil tube in its basic form as a carrier for a winding package and two flanges as respective axial boundaries of the winding frame.
Bei elektromagnetischen Relais wird häufig innerhalb der Erre¬ gerwicklung ein runder Magnetweicheisen-Kern zur Flußführung eingesetzt, weshalb der aus Isolierstoff bestehende und dieIn the case of electromagnetic relays, a round magnetic soft iron core is often used to guide the flux within the excitation winding, which is why the insulating material and the

Auf dieses Spulenrohr wird in den Wick¬ lungsraum zwischen beiden Flanschen die Wicklung aus thermo¬ plastisch umhüllten Kupfer-Runddrähten unter Zug aufgebracht, so daß das Wicklungspaket zunächst fest und unbeweglich auf15 winding-carrying coil former also has a coil tube in the form of a cylinder.

Durch Temperatur- und Zeiteinflüsse schrumpft jedoch die Wick¬ lung als Folge einer Schrumpfung der Drahtisolierung, und das bedeutet, daß der Außendurchmesser und die Länge der WicklungDue to temperature and time influences, however, the winding shrinks as a result of a shrinkage of the wire insulation, and this means that the outside diameter and the length of the winding

Durch zusätzliche Krafteinwir¬ kungen von außen, wie Schwingungen, Schockbeanspruchung und Temperaturwechsel, besteht die Gefahr einer Unterbrechung der30 smaller, but the inner diameter becomes larger. As a result, the winding package on the coil tube is loose and can be moved in the axial and radial directions.

Such vibrational stresses occur in particular then when a relay is installed in a moving device, for example in a motor vehicle.
Aufgabe der Erfindung ist es, eine Spule der eingangs genann- ten Art so zu gestalten, daß derartige äußere Krafteinwirkun¬ gen auch bei einem Schrumpfen des- Wicklungspaketes nicht zu Verschiebungen oder Verdrehungen der Wicklung und damit zu ei¬ ner Gefährdung der Wicklungsenden führen können.The object of the invention is to design a coil of the type mentioned in such a way that such external forces, even when the winding package shrinks, cannot lead to displacements or rotations of the winding and thus to a risk to the winding ends.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß auf dem Außenumfang des Spulenrohres mindestens ein in das Wicklungs¬ paket eingreifender Vorsprung ausgebildet ist. Vorzugsweise wird eine Mehrzahl von nasenför igen oder kegelförmigen Vor¬ sprüngen in einer gemeinsamen radialen Ebene über den Umfang des Spulenrohres verteilt angeordnet. Durch die Anordnung der Vorsprünge in einer einzigen radialen Ebene wird vermieden, daß Spannungen innerhalb des Wicklungspaketes durch die Vor¬ sprünge hervorgerufen werden. Weiterhin ist es zweckmäßig, den Vorsprung oder die Vorsprünge in der Nähe desjenigen Spulen- flansches anzuordnen, an dem die Wicklungsanfänge bzw. -enden befestigt sind. Damit wird sichergestellt, daß eine schrump¬ fende Wicklung in die Richtung des gefährdeten Wicklungsanfan¬ ges gezogen und somit dessen Beanspruchung in Längsrichtung vermieden wird.According to the invention, this object is achieved in that at least one projection engaging in the winding package is formed on the outer circumference of the coil tube. A plurality of nasal or conical projections is preferably arranged in a common radial plane distributed over the circumference of the coil tube. The arrangement of the projections in a single radial plane prevents tensions within the winding package from being caused by the projections. Furthermore, it is expedient to arrange the projection or the projections in the vicinity of the coil flange to which the winding starts or ends are fastened. This ensures that a shrinking winding is pulled in the direction of the end of the winding at risk and thus the stress in the longitudinal direction is avoided.
Anstelle von Vorsprüngen aus einer durchgehend kreisförmigen Mantelfläche heraus kann auch vorgesehen werden, daß der Au¬ ßenumfang des" Spulenrohres mindestens eine Abflachung auf¬ weist, aus der ein Vorsprung in Form einer Wulst hervorsteht. Diese Wulst kann beispielsweise als Fortsetzung des Kreisquer¬ schnittes des sonstigen Spulenrohrumfanges ausgebildet sein.Instead of projections from a continuously circular envelope surface out can also be provided that the Au¬ ßenumfang the "coil tube has auf¬ at least one flat from which a projection in the form of a bead protrudes. This bead may, for example, as a continuation of Kreisquer¬ section of the other coil tube circumference.
Die Erfindung wird nachfolgend an Ausführungsbeispielen anhand der Zeichnung näher erläutert. Es zeigtThe invention is explained in more detail below using exemplary embodiments with reference to the drawing. It shows
Figur 1 und 2 einen Spulenkörper mit angedeuteter Wicklung in teilweise geschnittener Seitenansicht sowie im Querschnitt, Figur 3 und 4 eine weitere Ausführungsform eines Spulenkörpers in perspektivischer Schnittdarstellung sowie in Seitenansicht.1 and 2 a coil former with indicated winding in a partially sectioned side view and in cross section, Figures 3 and 4, a further embodiment of a coil body in a perspective sectional view and in side view.
Die in den Figuren 1 und 2 gezeigte Spule besitzt einen Spu- lenkδrper 1, der ein Spulenrohr 2 sowie zwei Flansche 3 und 4 besitzt. Das Spulenrohr 2 besitzt einen kreisrunden Quer¬ schnitt und eine Innenbohrung zur Aufnahme eines nicht darge¬ stellten Eisenkerns. Auf den Außenumfang des Spulenrohrs 2 wird eine Wicklung 5 aus thermoplastisch umhüllten. Kupferdraht gewickelt. Dabei wird der Wicklungsanfang 6 zunächst an einem Anschlußstift 7 befestigt, der in dem Spulenflansch 3 veran¬ kert ist.The coil shown in FIGS. 1 and 2 has a coil body 1 which has a coil tube 2 and two flanges 3 and 4. The coil tube 2 has a circular cross section and an inner bore for receiving an iron core (not shown). On the outer circumference of the coil tube 2, a winding 5 made of thermoplastic is wrapped. Wrapped copper wire. The beginning of the winding 6 is first fastened to a connecting pin 7 which is anchored in the coil flange 3.
Durch Temperatureinflüsse und Alterung entsteht durch Verbak- ken der Drahtisolierung ein kompaktes Wicklungspaket 5, das nach einer gewissen Zeit lose auf dem Spulenrohr 2 sitzen kann. Um dabei eine Verdrehung oder eine Axialbewegung zu ver¬ meiden, besitzt das Spulenrohr 2 kegelförmige Noppen 8, die in der Nähe des Wicklungsanfangs 6 auf einer gemeinsamen radialen Ebene angeordnet sind. Diese Noppen 8 bohren sich bereits beim Aufbringen der Wicklung von innen in das Wicklungspaket und verhindern somit eine spätere Bewegung. Da die Noppen 8 in der Nähe des Spulenflansches 3 liegen, wird das schrumpfende Wick¬ lungspaket in die Richtung des gefährdeten Wicklungsanfangs 6 gezogen, so daß eine Beanspruchung in Längsrichtung vermieden wird.Due to temperature influences and aging, a compact winding package 5 is formed by the wire insulation becoming baked, which can sit loosely on the coil tube 2 after a certain time. In order to avoid twisting or axial movement, the coil tube 2 has conical knobs 8, which are arranged near the start of the winding 6 on a common radial plane. These knobs 8 already drill into the winding package from the inside when the winding is applied and thus prevent later movement. Since the knobs 8 are in the vicinity of the coil flange 3, the shrinking winding package is pulled in the direction of the end of the winding 6 at risk, so that stress in the longitudinal direction is avoided.
In den Figuren 3 und 4 ist eine etwas abgewandelte Ausfüh¬ rungsform gezeigt. Ein Spulenkörper 11 besitzt in diesem Fall ein Spulenrohr 12 mit Flanschen 13 und 14. Auf dem Spulenrohr ist eine Wicklung 15 aufgebracht, wobei ein Wicklungsanfang 16 an einem Anschlußstift 17 im Spulenflansch 13 befestigt ist.A somewhat modified embodiment is shown in FIGS. 3 and 4. In this case, a coil former 11 has a coil tube 12 with flanges 13 and 14. A winding 15 is applied to the coil tube, with a winding start 16 being fastened to a connecting pin 17 in the coil flange 13.
Das Spulenrohr 12 besitzt in diesem Fall seitliche Abflachun- gen 18, so daß das an den Außenumfang des Spulenrohrs angepa߬ te Wicklungspaket 15 auch bei einer gewissen Schrumpfung nicht auf dem Spulenrohr verdreht werden kann. Um auch eine Axial- .erschiebung des Wicklungspaketes 15 zu verhindern, ist die Abflachung 18 jeweils durch eine Wulst 19 in der Nähe des Wicklungsanfangs 16 unterbrochen, wobei die Wulst in diesem Fall als Fortsetzung der Kreismantelfläche des Spulenrohres 12 ausgebildet ist. In this case, the coil tube 12 has lateral flats 18, so that the winding package 15, which is adapted to the outer circumference of the coil tube, cannot be rotated on the coil tube even with a certain shrinkage. To also have an axial To prevent displacement of the winding package 15, the flattening 18 is interrupted in each case by a bead 19 in the vicinity of the start of the winding 16, in which case the bead is designed as a continuation of the circular surface of the coil tube 12.
