Abstract
Description
Die Erfindung betrifft ein elektromagnetisches Relais mit
- einer auf einem Spulenkörper zwischen Spulenflanschen angeordneten Spulenwicklung,
- einem T-förmigen Kern mit einem Längsschenkel und zwei Querschenkeln, wobei der Längsschenkel sich axial durch den Spulenkörper erstreckt,
- einem U-förmigen Anker mit zwei beiderseits der Spule verlaufenden Längsarmen und einem Quersteg, wobei der Anker mit einem ersten Endabschnitt im Bereich eines ersten Spulenflansches auf einem Endabschnitt des Kerns gelagert ist und mit seinem zweiten Endabschnitt im Bereich des zweiten Spulenflansches einen Arbeitsluftspalt mit dem Kern bildet, und
- einer Kontaktanordnung mit mindestens einem feststehenden Kontaktelement und mindestens einer beweglichen Kontaktfeder, welch letztere von dem Anker über ein quer zur Spulenachse bewegbares Betätigungsorgan betätigt wird.
- a coil winding arranged on a coil former between coil flanges,
- a T-shaped core with a longitudinal leg and two transverse legs, the longitudinal leg extending axially through the coil former,
- a U-shaped armature with two longitudinal arms running on both sides of the coil and a crossbar, the armature having a first end section in the area of a first coil flange being mounted on an end section of the core and with its second end section in the area of the second coil flange a working air gap with the core forms, and
- a contact arrangement with at least one fixed contact element and at least one movable contact spring, the latter being actuated by the armature via an actuating member movable transversely to the coil axis.
Ein derartiges Relais ist beispielsweise aus der DE 34 43 094 Al bekannt. Dort ist der T-förmige Kern durch Fortsätze an den Enden der Querschenkel, die sich parallel zum Mittelschenkel erstrecken, zu einer E-Form oder M-Form erweitert. Der U-förmige Anker ist mit den Enden seiner Längsarme auf diesen Fortsätzen des Kerns gelagert, so daß sein Quersteg den Arbeitsluftspalt mit dem freien Ende des Mittelschenkels des Kerns bildet. Diese Art der Ankerlagerung auf einem E-förmigen Kern erfordert in jedem Fall zusätzliche Lagerelemente in Form einer Lagerfeder, die nicht nur einen entsprechenden Aufwand bei der Herstellung mit Stanzen und Biegen, sondern auch bei der Montage mit entsprechenden Justier- und Niet- oder Schweißvorgängen erfordert. Auf andere Weise kann aber ein derartiger Anker nicht in seiner Lagerung gesichert werden. Außerdem ergibt sich zwischen dem Anker-Querschenkel und dem Kernende nur eine relativ geringe Polfläche im Arbeitsluftspalt, die auch nicht ohne weiteres vergrößert werden kann.Such a relay is for example from DE 34 43 094 Al known. There the T-shaped core is attached by extensions the ends of the cross legs that are parallel to the middle leg extend to an E-shape or M-shape. The U-shaped anchor is on with the ends of its longitudinal arms these extensions of the core stored so that its crossbar the working air gap with the free end of the middle leg of the nucleus. This type of anchor bearing on an E-shaped Kern always requires additional bearing elements in the form of a bearing spring that is not just a corresponding one Manufacturing effort with punching and bending, but also during assembly with appropriate adjustment and Riveting or welding operations required. In other ways but such an anchor is not secured in its storage become. In addition, there is between the anchor cross leg and the core end has only a relatively small pole area in the working air gap, which are also not easily enlarged can.
Ziel der vorliegenden Erfindung ist es, ein Relais der eingangs genannten Art so zu gestalten, daß es mit nur wenigen, einfach gestalteten und einfach herzustellenden Teilen auf besonders einfache Weise montiert werden kann, wobei trotzdem eine zuverlässige Funktion und eine hohe Ansprechsicherheit durch eine verhältnismäßig große Polfläche im Arbeitsluftspalt erreichbar sind.The aim of the present invention is to provide a relay of the input mentioned type in such a way that with only a few, simply designed and easy to manufacture parts can be assembled in a particularly simple manner, although a reliable function and a high level of responsiveness due to a relatively large pole area in the working air gap are reachable.
Erfindungsgemäß wird dieses Ziel dadurch erreicht, daß der Anker über seinen Quersteg auf dem freien Endabschnitt des Längsschenkels des Kerns gelagert ist und daß die freien Enden der Anker-Längsarme mit den freien Enden der Kern-Querschenkel zwei parallele Arbeitsluftspalte bilden.According to the invention this goal is achieved in that the Anchor over its crossbar on the free end section of the Longitudinal leg of the core is mounted and that the free ends the anchor longitudinal arms with the free ends of the core cross legs form two parallel working air gaps.
Bei dem erfindungsgemäßen Relais sind also im Vergleich zu dem bekannten Relais die Ankerlagerung und der Arbeitsluftspalt vertauscht angeordnet, so daß das U-förmige Ende des Ankers den ersten Spulenflansch umschließt und so bereits durch seine Anordnung in Längsrichtung der Spulenachse gesichert ist. Da eine Sicherung des Ankers auch in andere Richtungen im Bereich eines Spulenflansches durch einfache konstruktive Gestaltung möglich ist, erübrigt sich eine Lagerfeder mit ihrem entsprechenden Herstellungs- und Montageaufwand. Andererseits ermöglichen die beiden parallelen Arbeitsluftspalte an den freien Enden des Ankers eine verhältnismäßig große Polfläche. Diese Polfläche kann zusätzlich dadurch vergrößert werden, daß die Kern-Querschenkel an ihren Enden jeweils mit Fortsätzen in Richtung auf die Anker-Längsarme hin versehen werden, so daß die T-Form des Kerns andeutungsweise in eine M-Form bzw. E-Form erweitert wird.In the relay according to the invention are therefore compared to the well-known relay, the armature bearing and the working air gap reversed so that the U-shaped end of the armature encloses the first coil flange and thus already secured by its arrangement in the longitudinal direction of the coil axis is. Because the anchor is also secured in other directions in the area of a coil flange by simple constructive Design is possible, a bearing spring is unnecessary with their corresponding manufacturing and assembly costs. On the other hand, the two parallel working air gaps enable a proportionate at the free ends of the anchor large pole face. This pole face can additionally be enlarged that the core cross legs at their ends each with extensions towards the anchor longitudinal arms be provided so that the T-shape of the core is suggestive is expanded into an M-shape or E-shape.
Zur Sicherung des Ankers in seiner Lagerung weist der erste Spulenflansch in einer bevorzugten Ausführungsform einen Ansatz auf, wobei dieser Ansatz und der Anker ineinandergreifende Vorsprünge und/oder Ausnehmungen aufweisen. Eine weitere Sicherung des Ankers in seiner Lagerung kann dann durch eine aufgesteckte Gehäusekappe erfolgen.To secure the anchor in its storage, the first points Coil flange in a preferred embodiment an approach on, this approach and the anchor interlocking Have projections and / or recesses. Another The anchor can then be secured in its storage by an attached housing cap.
Die durch den Anker betätigte Kontaktfeder wird vorzugsweise annähernd parallel zur Spulenachse auf der dem Anker gegenüberliegenden Seite der Spule angeordnet, wobei die Übertragung der Ankerbewegung auf die Kontaktfeder durch einen Schieber erfolgt, der zwischen den Querschenkeln des Kerns einerseits und dem benachbarten Spulenflansch andererseits senkrecht zur Spulenachse beweglich geführt ist. Auch für den Schieber kann ein Ansatz der erwähnten Gehäusekappe eine zusätzliche Führung erbringen.The contact spring actuated by the armature is preferred approximately parallel to the coil axis on the opposite side of the armature Side of the coil arranged, the transmission the armature movement on the contact spring by a Slider takes place between the transverse legs of the core on the one hand and the adjacent coil flange on the other is movably guided perpendicular to the coil axis. Also for that Slider can be an approach to the mentioned housing cap an additional Provide leadership.
Der erste Spulenflansch kann über den Ansatz zur Ankerlagerung hinaus einen Fortsatz in Form eines Sockels aufweisen, welcher eine Bodenebene festlegt, auf der die Spulenachse senkrecht steht. Die erwähnte, mindestens eine, Kontaktfeder und das mindestens eine Gegenkontaktelement werden dann zweckmäßigerweise senkrecht zur Bodenebene in dem Sockel verankert, wobei zugehörige Anschlußstifte durch den Sockelboden senkrecht nach außen geführt sind. Für die kontaktgebenden Enden dieser Kontaktelemente ist vorzugsweise an dem zweiten Spulenflansch zumindest ein Anschlag vorgesehen, der die Ruheposition des Gegenkontaktelementes und/oder der Kontaktfeder definiert.The first coil flange can be attached to the armature bearing also have an extension in the form of a base, which defines a floor level on which the coil axis is vertical. The mentioned, at least one, contact spring and then the at least one counter-contact element conveniently anchored in the base perpendicular to the floor plane, associated pins through the base are guided vertically outwards. For the contact person The ends of these contact elements are preferably at the second Coil flange at least one stop provided, the rest position the counter-contact element and / or the contact spring Are defined.
Die beweglichen Enden der Anker-Längsarme werden vorzugsweise durch eine Rückstell-Federkraft vom Kern weg in eine Ruheposition vorgespannt, und außerdem ist vorzugsweise im Mittelbereich dieser Längsschenkel jeweils ein Drehpunkt durch einen Anschlag an einem Gehäuseteil vorgesehen, über den die Rückstell-Federkraft den Quersteg des Ankers in seine Lagerung am Kern drückt. Damit ist auch ohne Lagerfeder sichergestellt, daß der Anker in seiner Ruheposition den geringstmöglichen Luftspalt zum Kern aufweist, wodurch sich ein guter Flußübergang und eine hohe Ansprechempfindlichkeit ergeben. Da diese Rückstell-Federkraft vorzugsweise durch die Kontaktfeder aufgebracht wird, kann die Zahl der Einzelteile des Relais besonders klein gehalten werden. Der Drehpunkt im Mittelbereich des Ankers kann durch seitlich angeformte Schultern der Anker-Längsarme in Verbindung mit einer entsprechenden Rippe oder Nut an der Innenseite der Gehäusekappe erzeugt werden, so daß auch hierfür keine zusätzlichen Teile oder Montagevorgänge erforderlich sind.The movable ends of the anchor arms are preferred a restoring spring force away from the core to a rest position biased, and also is preferably in the central region this longitudinal leg is a fulcrum by one Stop provided on a housing part over which the Return spring force the crossbar of the anchor in its storage presses at the core. This ensures even without a bearing spring that the anchor in its rest position the least possible Has air gap to the core, which makes a good Flow transition and a high sensitivity. Since this return spring force is preferably by the contact spring is applied, the number of individual parts of the relay be kept particularly small. The center of rotation the anchor can be formed by shoulders on the sides the anchor longitudinal arms in connection with a corresponding Rib or groove created on the inside of the housing cap are, so that no additional parts or Assembly operations are required.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel
anhand der Zeichnung näher erläutert. Es zeigt
Das in der Zeichnung dargestellte Relais besteht aus einem
Spulenkörper 1, einem T-förmigen oder annähernd M-förmigem
Kern 2, einem U-förmigen Anker 3, einem kartenförmigen Schieber
4, einer feststehenden Kontaktfeder 5, einer beweglichen
Kontaktfeder 6, einer Kappe 7 sowie zwei im Spulenkörper verankerten
Spulenanschlußstiften 8.The relay shown in the drawing consists of a
Coil body 1, a T-shaped or approximately M-
Der Spulenkörper 1 besitzt eine axiale Durchgangsöffnung 11
sowie einen ersten Flansch 12 und einen zweiten Flansch 13,
zwischen denen eine Wicklung 14 aufgebracht wird. Stirnseitig
ist am Spulenflansch 12 einstückig ein Ansatz 14 zur Ankerlagerung
angeformt, der in eine Sockelplatte 15 übergeht. An
dem Ansatz 14 sind weiterhin Begrenzungszapfen 16 für den Anker
angeformt, außerdem sind in diesen Ansatz Steckschlitze
17 eingeformt, durch die Anschlußelemente 51 bzw. 61 der Kontaktfedern
5 und 6 durch die Sockelplatte 15 senkrecht nach
außen geführt werden können. An dem zweiten Spulenflansch 13
ist außerdem eine Anschlagnase 18 für die feststehende Kontaktfeder
5 angeformt.The coil former 1 has an axial through opening 11
and a
Der T-förmige Kern 2 besitzt einen Längsschenkel 21, der in
die Durchgangsöffnung 11 des Spulenkörpers eingeführt wird,
sowie zwei Querschenkel 22, an deren Enden jeweils Seitenarme
23 parallel zum Längsschenkel 21 angesetzt sind. Der U-förmige
Anker 3 besteht aus zwei Längsarmen 31 und einem
Quersteg 32, welch letzterer auf dem freien Endabschnitt 24
des Kerns 2 gelagert wird und dann in einer Ausnehmung zwischen
dem ersten Spulenflansch 12 und der Sockelplatte 15
liegt. Durch die beiden Sicherungszapfen 16 des Sockelansatzes
14, die in entsprechende Ausnehmungen 33 des Ankers eingreifen,
ist er gegen seitliche Bewegungen gesichert, ohne
daß seine Schaltbewegung behindert wäre. Die freien Enden der
Längsarme 31 sind zu hakenförmigen Polenden 34 verbreitert,
die den zweiten Spulenflansch 13 umgreifen und mit den Querschenkeln
22 sowie deren Seitenarmen 23 des Kerns zwei parallele
Arbeitsluftspalte bilden.The T-
Die feststehende Kontaktfeder 5 und die bewegliche Kontaktfeder
6 sind mit ihren Anschlußelementen 51 bzw. 61, welche
einstückig angeformt oder auf bekannte Weise befestigt sind,
in den Steckschlitzen 17 des Sockelansatzes 14 verankert. Im
vorliegenden Beispiel sind die beiden Kontaktfedern 5 und 6
identisch ausgeführt und mit Kontakten 52 bzw. 62 versehen.
Die gegenseitige Überlappung zur Kontaktgabe ergibt sich
durch eine L-förmige Abwinkelung an ihren beweglichen, kontaktgebenden
Enden.The fixed
Die Kontaktfedern 5 und 6 sind ohne Biegung lediglich aus einer
ebenen Blechplatine geschnitten und in den Spulenkörper
eingesteckt. Der gegenseitige Versatz ihrer kontaktgebenden
Enden ergibt sich lediglich aus der Geometrie des Spulenkörpers
bzw. des Schiebers 4. Dieser Schieber liegt zwischen dem
Spulenflansch 13 und den Querschenkeln 22 des Kerns. Er besitzt
eine Ausnehmung 41, durch die der Kern-Längsschenkel 21
hindurchgesteckt wird. Nach dem Zusammenfügen der Teile liegt
der L-förmig abgebogene Endabschnitt 63 der beweglichen Kontaktfeder
6 an der Anschlagnase 18 des Spulenkörpers 1 an und
erhält so seine Ruhevorspannung. Andererseits liegt der L-förmig
abgebogene Endabschnitt 53 der feststehenden Kontaktfeder
5 an dem Schieber 4 an. Bei Betätigung des Schiebers 4
durch den Anker wird der Endabschnitt 53 in Richtung auf den
Endabschnitt 63 der festehenden Kontaktfeder 6 bewegt, und
sie hebt letztere von ihrem Anschlag an der Nase 18 ab. Auf
diese Weise entsteht die Kontaktkraft.The
Nach der Montage der beschriebenen Einzelteile wird die Kappe
7 über das Relais gestülpt. Sie bildet mit der Sockelpiatte
15 ein geschlossenes Gehäuse. Wie aus Figur 4 ersichtlich
ist, weist die Kappe 7 im Bereich ihrer Oberseite ein Lüftungsloch
71 auf, das in einen nach innen vorstehenden Ansatz
72 mündet. Letzterer Ansatz bildet eine zusätzliche Führung
für den Schieber 4. Wie aus Figur 4 weiter ersichtlich ist,
wird der Anker 3 über den Schieber 4 durch die Rückstellkraft
der Arbeitskontaktfeder 6 in seine Ruheposition vorgespannt.
Dabei stoßen seitliche Schultern 35 des Ankers an Rippen 72
der Kappe an, wodurch ein Drehpunkt 73 für den Anker gebildet
wird. Über diesen Drehpunkt 73 wird durch die Hebelwirkung
das gelagerte Ende bzw. der Quersteg 32 des Ankers in die Lagerung
und gegen den Endabschnitt 24 des Kerns gedrückt. Dadurch
ergeben sich reproduzierbare Flußübergangsverhältnisse
in der Ankerlagerung und eine entsprechend niedrige Ansprecherregung.After assembling the individual parts described, the
