Description
Die Erfindung betrifft einen Temperaturschutzschalter gemäß
dem Oberbegriff des Anspruchs 1.The invention relates to a temperature protection switch according to
the preamble of
Temperaturschutzschalter sind hinreichend bekannt. Gegenüber offenen Temperaturschutzschaltern werden geschlossene Ausführungen überall dort verwendet, wo die Kontakteinrichtung eines Schutzes bedarf, sei es vor mechanischer Einwirkung, wie z.B. dem Druck bei der Herstellung einer Wicklung, oder gegen Umwelteinflüsse.Temperature protection switches are well known. Across from open temperature protection switches become closed versions used wherever the contact device a Protection is required, be it against mechanical influences, e.g. the pressure in the manufacture of a winding, or against Environmental influences.
Eine für allgemeine Zwecke, verwendbare Ausführung eines Temperaturschutzschalters
gemäß Oberbegriff von Patentanspruch 1 zeigt die US-Patentschrift 3,747,208. In
einem Sockel mit rundem Querschnitt aus einem Isoliermaterial
ist eine aus zwei Bimetallfedern bestehende Kontakteinrichtung
gehaltert. Der Sockel hat am vorderen Ende einen stufenförmigen
Absatz, auf den eine die Kontakteinrichtung schütztende
zylindrische Kappe aufgesteckt ist. - Als Wicklungsschutzschalter
ist diese Ausführung wegen ihres runden Querschnitts
ungeeignet, da sie beim Überwickeln eine zu starke Auswölbung
verursacht.A version of a temperature protection switch that can be used for general purposes
according to the preamble of
Eine als Wicklungsschutzschalter geeignete Ausführung ist durch die US-Patentschrift 4,866,408 bekannt. Bei dieser ist eine flach ausgebildete Kontakteinrichtung in einer Kopfplatte aus Metall isoliert gehaltert. Eine die Kontakteinrichtung schützende flache Kappe aus Metall, die einen rechteckigen Querschnitt hat, ist mit der Kopfplatte hermetisch verschweißt. - Die den Fertigungsprozess des Schalters abschließende Wärmebehandlung durch das Verschweißen kann sich auf die voreingestellte Ansprechtemperatur negative auswirken. Außerdem ist die Schutzkappe nur bedingt druckstabil.A version suitable as a winding protection switch is known from U.S. Patent No. 4,866,408. With this one a flat contact device in a head plate insulated from metal. A the contact device protective flat metal cap that has a rectangular Cross section, is hermetic with the head plate welded. - The one that completes the switch manufacturing process Heat treatment by welding can have a negative impact on the preset response temperature. In addition, the protective cap is only partially stable under pressure.
Eine weitere bekannte Ausführung eines gekapselten Temperaturschutzschalters mit einem flachen rechteckigem Querschnitt ist der Wicklungsprotektor 9700 der Firma Texas Instruments Holland B.V., der als temperaturabhängiger und/oder stromabhängiger Schalter eingesetzt werden kann. Das flache Schutzgehäuse, das auf einen Ansatz des die Kontakteinrichtung tragenden Sokkels aufgesteckt ist, und die Kontakteinrichtung selbst sind sind so ausgebildet, daß eine Justage des Schaltelementes noch im montierten Zustand des Temperaturwächters durch Verbiegen des freien Endes des Gehäuses erfolgen kann. - Durch die Art der Schaltelementjustage und der dadurch bedingten Gehäuseform ist dieser Temperaturschutzschalter gegenüber Druck von außen empfindlich. Für den Einsatz in Motor- und Transformatorenwicklungen ist diese Art daher nicht optimiert.Another known version of an encapsulated temperature protection switch with a flat rectangular cross section the winding protector 9700 from Texas Instruments Holland B.V., which as a temperature-dependent and / or current-dependent Switch can be used. The flat protective housing, that on an approach of the Sokkels carrying the contact device is plugged in, and the contact device itself are designed so that an adjustment of the switching element is still in the assembled state of the temperature monitor by bending the free end of the housing can be done. - By Art the switching element adjustment and the resulting housing shape is this temperature protection switch against external pressure sensitive. For use in motor and transformer windings this type is therefore not optimized.
Die Aufgabe der Erfindung besteht daher darin, einen Temperaturschutzschalter mit einem flachen Gehäusequerschnitt zu schaffen, der sich bezüglich seiner Druckfestigkeit besonders für die Verwendung im Elektromotoren- und Transformatorenbau eignet.The object of the invention is therefore a temperature protection switch with a flat housing cross section create, which is special in terms of its compressive strength for use in electric motor and transformer construction is suitable.
Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale
gelöst. Die Unteransprüche zeigen vorteilhafte Ausgestaltungen
des Erfindungsgegenstandes auf. This object is achieved by the features specified in
Die durch die Erfindung erzielten Vorteile bestehen insbesondere darin, daß das flache Gehäuse durch seine allseitig nach außen gewölbte Wandung besonders druckstabil ist. Die Stabilität wird durch die in das Gehäuse formschlüssig ragenden Ausleger des Sockels und deren Versteifung durch die in sie eingebettete Trägerplatte erhöht.The advantages achieved by the invention are in particular in that the flat housing due to its all-round outside arched wall is particularly pressure-resistant. The stability is due to the projecting into the housing Cantilever of the base and its stiffening by the in it embedded carrier plate increased.

Fig.1 zeigt einen Temperaturschutzschalter in Draufsicht, bei
der die obere Hälfte eines Gehäuses 10 (Fig.2) entfernt ist.
Das Gehäuse ist auf einen Ansatz 1a eines Sockels 1 aufgeschoben.
Letzterer besteht aus einem Isolierstoff. Die Ansicht
gibt den Blick in das Innere des Gehäuses 10 frei, das im
wesentlichen eine auf thermische Veränderungen ansprechende
Kontakteinrichtung umschließt. Letztere besteht aus einem
Festkontakt 3 und einer U-förmigen Trägerplatte 4, die über
eine Lasche 5 mit einer Thermobimetallscheibe 7 und einem
Trimmbügel 8 formschlüssig leitend verbunden ist. Der Festkontakt
3 besteht aus einem mit einem Kontakt 3c versehenen
Träger 3a, der im Sockel 1 verankert ist, und mit einem von
außen zugänglichen Anschluß 3b ein Teil bildet. Der Sockel 1
hat in Fortsetzung des Ansatzes 1a seitlich angeordnete Ausleger
1b, in denen die Trägerplatte 4 mit den sich aus der
U-Form ergebenden Schenkeln 4a in der strichliniert dargestellten
Weise verankert ist. Einer der Schenkel 4a ist durch
den Sockel 1 hindurchgeführt und bildet mit einem Anschluß 4b
ein Teil.Fig.1 shows a temperature protection switch in plan view, at
the upper half of a housing 10 (Fig.2) is removed.
The housing is pushed onto an extension 1a of a
Fig.2 zeigt den Temperaturschutzschalter der Fig.1 im Schnitt
II-II. Wie diese Dastellung erkennen läßt, ist die Trägerplatte
4 zur Lasche 5 stufenförmig abgekröpft. Die mit der
Lasche 5 verbundene Thermobimetallscheibe 7 ist in Ausrichtung
auf den Kontakt 3c des Festkontaktes 3 am freien Ende mit
einem Gegenkontakt 7a versehen. Durch den von unten an der
Thermobimetallscheibe 7 anliegenden Trimmbügel 8 wird in bekannter
Weise der Kontaktdruck zwischen 3c und 7a so eingestellt,
daß die Thermobimetallscheibe 7 bei einer Erwärmung
auf eine vorgegebenen Temperatur sprunghaft anspricht und dadurch
die beiden Kontakte 3c und 7a trennt. Je nach Höhe der
zu schaltenden Stromstärke bildet sich beim Öffnungsvorgang
zwischen den Kontakten 3c und 7a ein mehr oder weniger starker
Lichtbogen. Zum Schutz der Stirnfläche des Sockelansatzes 1a
gegen die dabei entstehende Hitze ist der Träger 3a gemäß
Fig.2 derart Z-förmig abgekröpft, daß der Ansatz 1a in der
Berührungsebene der beiden Kontakte 3c und 7a auf der Breite
des Trägers 3a geschützt ist. Durch Hitzeeinwirkung kann
der z.B. aus einem Kunststoff bestehende Sockel so stark
beeinträchtigt werden, daß Teile vergasen, die sich auf den
Kontaktflächen niederschlagen und zu Funktionsstörungen
führen können.Fig.2 shows the temperature protection switch of Fig.1 in section
II-II. As can be seen from this illustration, the
Fig.3 zeigt den Temperaturschutzschalter der Fig.1 im Schnitt
III-III der Fig.2. Dieser Querschnitt zeigt das Gehäuse 10,
dessen Wandung allseitig nach außen gewölbt ist. Gemäß Fig.1
ist auch die Stirnfläche nach außen gewölbt. Diese Maßnahme
und eine noch zu beschreibende Versteifung von innen ergibt
ein außerordentlich druckstabiles Gehäuse 10, das dem hohen
Druck beim Herstellen der Wicklung, z.B. beim Überwickeln des
eingebauten Temperaturschutzschalters oder beim Verpressen
der Wicklung standhält. Die Versteifung im Inneren des Gehäuses
10 erfolgt durch die bereits erwähnten Ausleger 1b des
Sockels 1. Diese sind, wie der Ansatz 1a des Sockels 1 selber,
dem Innenprofil des Gehäuses 10 angepaßt und liegen kraftschlüssig
an der Gehäuseinnenwand an. Dafür, daß die Ausleger
1b bei Druck von außen nicht nachgeben, sorgt die mit ihren
Schenkeln 4a in ihnen verankerte Trägerplatte 4 als starre
Verbindung. Die Trägerplatte 4 hat gemäß Fig.3 außerhalb der
Verankerung abgewinkelte Längskanten 6. Diese können leicht
nach außen gespreizt sein, so daß sie bei aufgeschobenem Gehäuse
10 kraftschlüssig an der Gehäuseinnenwand anliegen. Eine
Alternative zeigen die Fig.1, 2 und 3, bei der der untere Teil
der Längskanten 6 als nach außen verstellbare Laschen 6a ausgebildet
sind. Diese liegen dann kraftschlüssig an der Gehäuseinnenwand
an. Außer der versteifenden Wirkung hat die vorzugsweise
flächenhafte Berührung zwischen dem Träger 4 und dem
Gehäuse 10 den Vorteil, daß außer der stromabhängigen Überwachung
auch Temperatureinflüsse von außen über das Gehäuse 10
und die Trägerplatte 4 der Thermobimetallscheibe 7 zugeführt
werden. Fig.3 shows the temperature protection switch of Fig.1 in section
III-III of Fig.2. This cross section shows the
Die gewölbte Querschnittsform des Sockelansatzes 1a und des
Gehäuses 10 ermöglichen von sich aus schon eine gute Abdichtung.
Die Anforderungen an die Dichtheit erfordert weitere
Maßnahmen, wenn der Themperaturschutzschalter in Fällen verwendet
wird, in denen die Wicklungen bei Unterdruck in Tränklack
eingegossen werden.The curved cross-sectional shape of the base approach 1a and
Fig.2 zeigt eine Möglichkeit einer zusätzlichen Kapselung.
Der Ansatz 1a hat am Übergang zum Sockel 1 eine Keilnut 2a.
In diese wird der Rand des aufgeschobenen Gehäuses 10 umgebördelt.
Über die Nahtstelle ist sodann ein Stück Schrumpfschlauch
11 gezogen.2 shows a possibility of an additional encapsulation.
The approach 1a has a keyway 2a at the transition to the
Fig.4 zeigt eine weitere Möglichkeit der zusätzlichen Abdichtung.
In Abweichung vom Beispiel der Fig.1 bis Fig.3 hat hier
der Ansatz 1a des Sockels 1 etwa in der Mitte der Fläche eine
flache Nut 2b. In diese ist ein leicht überstehender Dichtungsring
9 eingelegt, oder die Nut 2b wird bei der Herstellung
des Sockels 1 im 2-Komponenten-Spritzverfahren mit einem
elastischen Kunststoff ausgefüllt, der leicht gewölbt
übersteht.Fig. 4 shows another way of additional sealing.
In deviation from the example of Fig.1 to Fig.3 here
the approach 1a of the
Je nach Anwendungsfall kann das Gehäuse 10 aus unterschiedlichen
Materialien bestehen. Ferromagnetische Materialien, wie
Stahl oder Mu-Metall, schützen die Kontakteinrichtung vor magnetischen
Blasfeldern. Bei hoher Feldstärke können sie den
sich beim Öffnen des Kontaktes bildenden Lichtbogen so stark
auslenken, daß er auf die Thermobimetallscheibe 7 überspringt.
Letztere wird dadurch zerstört. Wird nur Schutz vor einer Verschmutzung
der Kontakteinrichtung angestrebt, so kann das Gehäuse
10 aus einem tiefziehfähigen Material, z.B. Tombak,
oder aus einem Kunstoff bestehen.Depending on the application, the
