Description

Die Erfindung betrifft eine Magnetspule mit einem Magnetgehäuse und einer Wicklung mit Spulendraht sowie einem Steckergehäuse mit Anschlusskontakten, wobei die beiden aus der Spule herausgeführten Enden des Spulendrahtes mit den Anschlusskontakten verbunden sind.The invention relates to a magnetic coil with a magnet housing and a winding with coil wire and a connector housing with connection contacts, wherein the two led out of the coil ends of the coil wire are connected to the connection contacts.

Bei der Kontaktierung des Spulendrahtes mit den Anschlusskontakten muss sorgfältig gearbeitet werden, damit bei der nachfolgenden Ummantelung keine Drahtschleifen aus dem Verguss herausschauen. Außerdem muss darauf geachtet werden, dass die Spulendrähte bei der Kontaktierung nicht abreißen.Care must be taken when contacting the coil wire with the connection contacts so that no wire loops stick out of the encapsulation during the subsequent sheathing. In addition, care must be taken to ensure that the coil wires do not break during contact.

Der Erfindung liegt nun die Aufgabe zugrunde, eine einfache sichere Kontaktierung der Enden des Spulendrahtes mit dem Anschlusskontakten sicherzustellen.The invention is based on the object to ensure a simple secure contacting of the ends of the coil wire with the connection contacts.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst.According to the invention, this object is solved by the features of claim 1.

Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further embodiments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Magnetspule weist ein Magnetgehäuse und eine Wicklung mit Spulendraht sowie ein Steckergehäuse mit Anschlusskontakten auf, wobei die beiden aus der Spule herausgeführten Enden des Spulendrahtes mit den Anschlusskontakten verbunden sind. Weiterhin sind elastische Haltemittel vorgesehen, die mit den herausgeführten Enden des Spulendrahtes in einem Bereich zwischen Magnetgehäuse und Anschlusskontakt derart in Kontakt stehen, dass der Spulendraht im Bereich zwischen Magnetgehäuse und Haltemittel bzw. Haltemittel und Anschlusskontakt auf Spannung gehalten wird.The magnet coil according to the invention has a magnet housing and a winding with coil wire and a plug housing with connection contacts, wherein the two out of the coil led out ends of the coil wire are connected to the connection contacts. Furthermore, elastic holding means are provided which are in contact with the lead-out ends of the coil wire in a region between the magnet housing and the terminal contact such that the coil wire is held in tension in the region between the magnet housing and holding means or holding means and terminal contact.

Durch die elastische Spannung der Haltemittel wird zum einen verhindert, dass Drahtschleifen entstehen, die später aus dem Verguss herausschauen können. Zum anderen können hierdurch etwaige Fertigungstoleranzen ausgegtichen werden.Due to the elastic tension of the holding means, on the one hand, it is prevented that wire loops are formed, which can later emerge from the casting. On the other hand, any manufacturing tolerances can thereby be balanced out.

In einem bevorzugten Ausführungsbeispiel sind die Haltemittel als einseitig eingespannte Biegezungen ausgebildet, die an ihren freien Enden unter Vorspannung mit dem Spulendraht verbunden sind. Die freien Enden der Biegezungen können hierbei insbesondere hakenartig ausgebildet sein.In a preferred embodiment, the holding means are designed as cantilevered bending tongues, which are connected at their free ends under bias to the coil wire. The free ends of the bending tongues can in this case in particular be hook-shaped.

Das Steckergehäuse wird zweckmäßigerweise mittels eines Steckerhalters mit dem Magnetgehäuse verbunden. Nachdem der Steckerhalter üblicherweise aus Metall besteht, ist in einer weiteren Ausgestaltung der Erfindung vorgesehen, dass die elastische Haltemittel Absätze aufweisen, welche die Halteelemente im Bereich der Kontaktstellen mit den Spulendrähten auf Abstand zum Steckerhalter halten.The plug housing is suitably connected by means of a plug holder with the magnet housing. After the plug holder is usually made of metal, it is provided in a further embodiment of the invention that the elastic holding means have paragraphs which keep the holding elements in the region of the contact points with the coil wires at a distance from the plug holder.

Weitere Vorteile und Ausgestaltungen der Erfindung werden anhand der Beschreibung eines Ausführungsbeispieles und der Zeichnung näher erläutert.Further advantages and embodiments of the invention will be explained in more detail with reference to the description of an embodiment and the drawing.

Die in Fig. 1 dargestellte Magnetspule besteht im wesentlichen aus einem Magnetgehäuse 1 mit einer Wicklung mit Spulendraht 2 und einem Steckergehäuse 3 mit Anschlusskontakten 4, 5, wobei die beiden aus der Spule herausgeführten Enden 2a, 2b des Spulendrahtes 2 mit den Anschlusskontakten 4, 5 verbunden sind.The solenoid shown in Fig. 1 consists essentially of a magnet housing 1 with a winding with coil wire 2 and a connector housing. 3 with connection contacts 4, 5, wherein the two led out of the coil ends 2a, 2b of the coil wire 2 with the connection contacts 4, 5 are connected.

Weiterhin sind elastische Haltemittel 6, 7 vorgesehen, die mit den herausgeführten Enden 2a, 2b des Spulendrahtes in einem Bereich zwischen Magnetgehäuse 1 und Anschlusskontakten 4 bzw. 5 derart in Kontakt stehen, dass der Spulendraht im Bereich zwischen Magnetgehäuse und Haltemittel bzw. Haltemittel und Anschlusskontakt auf Spannung gehalten wird.Furthermore, elastic holding means 6, 7 are provided, which are in contact with the lead-out ends 2a, 2b of the coil wire in a region between the magnet housing 1 and connection contacts 4 or 5 such that the coil wire in the region between the magnet housing and holding means or holding means and terminal contact kept on tension.

Die Haltemittel 6, 7 sind im dargestellten Ausführungsbeispiel als einseitig eingespannte Biegezungen ausgebildet, die an ihren freien Enden 6a, 7a hakenartig ausgebildet sind, wie das insbesondere aus den Figuren 2 und 3 hervorgeht. Die freien Enden 2a, 2b des Spulendrahtes werden bei der Kontaktierung mit den Anschlusskontakten 4,5 etwas nach oben gebogen, so dass sie unter Vorspannung mit dem Spulendrähten verbunden sind.The holding means 6, 7 are formed in the illustrated embodiment as cantilevered bending tongues, which are hook-like at their free ends 6a, 7a, as is apparent in particular from Figures 2 and 3. The free ends 2a, 2b of the coil wire are bent slightly upward when contacting the connection contacts 4, 5, so that they are connected under prestress to the coil wires.

Die elastischen Haltemittel 6, 7 sind aus Kunststoff, insbesondere als Spritzgussteil, gefertigt, wobei sie zweckmäßigerweise einstückig mit dem Steckergehäuse ausgebildet sind (siehe Fig. 3). Weiterhin ist ein Steckerhalter 8 vorgesehen, der zur Verbindung des Steckergehäuses 3 mit dem Magnetgehäuse 1 dient.The elastic holding means 6, 7 are made of plastic, in particular as an injection molded part, wherein they are expediently formed integrally with the plug housing (see FIG. 3). Furthermore, a plug holder 8 is provided which serves to connect the plug housing 3 with the magnet housing 1.

Da der Steckerhalter 8 üblicherweise aus Metall gefertigt ist, muss im Bereich der Kontaktstelle der Halteelemente 6, 7 mit den Spulendrähten sichergestellt werden, dass kein elektrischer Kontakt zwischen Spulendraht und Steckerhalter entsteht. Dies kann auf einfache Weise dadurch gewährleistet werden, dass die Haltemittel bei der Montage etwas nach oben gebogen werden, so dass dann ein ausreichender Abstand gewährleistet ist.Since the plug holder 8 is usually made of metal, it must be ensured in the region of the contact point of the holding elements 6, 7 with the coil wires that no electrical contact between coil wire and plug holder is formed. This can be ensured in a simple manner, that the holding means are bent slightly upwards during assembly, so that then a sufficient distance is guaranteed.

Im dargestellten Ausführungsbeispiel sind die elastischen Haltemittel 6, 7 zusätzlich mit Absätzen 9, 10 versehen, die einen sicheren Abstand zwischen Spulendraht 2 und Steckerhalter 8 im Kontaktbereich zwischen Halteelement und Spulendraht gewährleisten.In the illustrated embodiment, the elastic holding means 6, 7 are additionally provided with paragraphs 9, 10, the safe distance between the coil wire 2 and Ensure connector holder 8 in the contact area between the holding element and the coil wire.
