Spulenkörper für elektromagnetisches RelaisCoil bobbin for electromagnetic relay
Jie Neuerung betrifft sin^n aus zwei Hälften zusammengesetzten "^ulenkörper für elektromagnetisches Heiais aus elektrisch iso- ?rendem Material.The innovation concerns sin ^ n composed of two halves "^ body for electromagnetic heat made of electrically iso- rending material.
Bei der laufenden Miniaturisierung vor Relais wird, es problematisch, Sicherheitsabstände wie Kriech- und Luftstreckenforderungen einzuhalten. Dazu gehört auch die sichere Trennung von Kontakt- und Spulenkreis. Bei Spulenkörpern, die aus Fertigungs— gründen aus 2 Hälften bestehen, ist die Nahtstelle im Bereich der Wicklung zwischen dem Kern des Relais und der untersten Wickel- Ιεζ,β besonders durchschlagsgefähr-iet.With the ongoing miniaturization in front of relays, it becomes problematic to adhere to safety distances such as creepage and clearance requirements. This also includes the safe separation of the contact and coil circuit. In the case of bobbins which, for manufacturing reasons, consist of 2 halves, the seam in the area of the winding between the core of the relay and the lowest winding Ιεζ, β is particularly at risk of breakdown.
Es sind Ausführungen bekannt, die eine genügend starke Materialdicke zwischen Wicklung und Metallkern verwenden. Nachteilig ist, daß dadurch der sog. Kerndurchmesser der Spule stark zunimmt und die Ausnutzung des Wickelraums erheblich verschlechert wird.There are known designs that have a sufficiently strong material thickness use between winding and metal core. The disadvantage is that this results in the so-called core diameter of the coil increases sharply and the utilization of the changing room deteriorates considerably will.
Aufgabe der Neuerung ist die Behebung des beschriebenen Mangels.The task of the innovation is to remedy the defect described.
Neuerungsgemäß wird die Aufgabe dadurch gelöst, wie das in den Schutzansprüchen 1-3 näher beschrieben ist.According to the innovation, the object is achieved as that in the Protection claims 1-3 is described in more detail.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden ausführlich beschrieben:An exemplary embodiment is shown in the drawing and is described in detail below:
Abbildung 1 zeigt einen Schnitt senkrecht zur Spulenkörperachse.Figure 1 shows a section perpendicular to the coil body axis.
Der Luftspalt (1), der die Kriechstrecke bildet, wird durch die Überlappung an der Stoßstelle verlängert. Diese Überlappung setzt sich auch über die Flanschinnenseiten fort.The air gap (1) that forms the creepage distance is created by the The overlap at the joint is extended. This overlap continues also continues on the inside of the flange.

Abbildung 2 zeig, die räumliche Darstellung des opulenkörpers mit eingesetztem Anker (8). Beide Spulinkörperhälften (1O umschließen den Kern 7 und werden von der Wicklung zusammengehalten. Der Spulenkörper ist an einer passenden Stelle im Bereich der Flansche zur Längsfixierung verzapft. Der Anker (8) bewegt sich zwischen den hochgezogenen Spulenkörperflanschen und diese besitzen einen Durchbruch (6) im Kontaktbereich zur Beobachtung der Justage des Kontakts, da der Anker zugleich als Kontaktträger und der Magnetkreis zugleich auch als elektrischer Schaltkreis verwendet wird. Die Aussparungen (5) an den Außenseiten der Spulenkö-perflansche (^f) dienen zum Spannen des Spulenkörpers während des .','ickelvorgangs. Die Lage und Form der Aussparungen ist so gewählt, daß ein sicheres Spannen und einwandfreier Rundlauf des onulenkörpers gewährleistet ist.Figure 2 shows the spatial representation of the opul body with inserted anchor (8). Both Spulinkörperhälften (1 O enclose the core 7 and are held together by the coil. The coil body is journalled at an appropriate point in the region of the flanges to the longitudinal fixation. The armature (8) moves between the raised bobbin flanges and they have a breakthrough (6) in the contact area to observe the adjustment of the contact, since the armature is used as a contact carrier and the magnetic circuit is also used as an electrical circuit. The recesses (5) on the outside of the coil body flanges (^ f) are used to tension the coil body during the. The position and shape of the recesses is chosen in such a way that a secure clamping and perfect concentricity of the onule body is guaranteed.
