Die Erfindung betrifft ein elektromagnetisches Relais, dessen die Erregerwicklung tragender Kern unlösbar
in einem gegen den Kern elektrisch isolierten Elektromagnetisches Relais mit gekapselter
Träger eingesetzt ist, und dessen den Träger durch- Kontaktanordnung
dringendes freies Kernende zusammen mit einem ge- 5
gegenüberstehenden Teil eines federgelagerten, magnetisierbaren Ankers einen Kontakt des Relais
bildet. The invention relates to an electromagnetic relay whose core, which carries the excitation winding, cannot be detached in an electromagnetic relay which is electrically isolated from the core and which is encapsulated
Carrier is used, and its the carrier through-contact arrangement
urgent free core end together with a 5
opposite part of a spring-loaded, magnetizable armature a contact of the relay
forms.
Elektromagnetische Relais dieser Art sind bekannt. So zeigt z. B. die USA.-Patentschrift 2 933 571 ein io Relais mit einem als elektrischer Leiter dienenden stabförmigen Kern, der in einen Träger unlösbar eingesetzt ist und mit einem durch eine tellerförmige Feder gehaltenen Anker als Relaiskontakt zusammenarbeitet. Trotz ihrer Einfachheit weist diese Anord- 15 nung verschiedene Nachteile auf, da bei diesem Relais die Kontaktanordnung nicht in einem hermetisch abgeschlossenen Raum untergebracht ist. Auch setzt die tellerförmige Feder mit ihren radial ausgebildeten Ausnehmungen einer leichten Ankerbeweg- 20 lichkeit einen verhältnismäßig großen Widerstand entgegen.Electromagnetic relays of this type are known. So shows z. U.S. Patent 2,933,571 an io Relay with a rod-shaped core serving as an electrical conductor, which is permanently inserted into a carrier is and cooperates with an armature held by a plate-shaped spring as a relay contact. Despite its simplicity, this arrangement has various disadvantages, since this relay the contact arrangement is not housed in a hermetically sealed space. Even sets the plate-shaped spring with its radially formed recesses a slight anchor movement 20 opposition to a relatively large resistance.
