Abstract

A preferably push button-actuated overload protective circuit breaker with bimetal cut-out is devised for being plugged into a flat female plug socket. The circuit breaker comprises a bimetal contact element and a fixed contact element besides each other and consisting each of an elongated punched-out part of substantially flat right parallelepiped shape. They have outer ends protruding out of a circuit breaker housing and lying with their flat longitudinal sections in the same plane, while their inner free ends inside the housing have their flat longitudinal sections lying in two different planes which are parallel with, but spaced from each other. A bimetal snap element is fastened at one end thereof, on the inner free end of the bimetal contact element and overlaps with its opposite slewable end, which bears a bimetal contact post, the inner free end of the fixed contact element and a fixed contact post thereon. In their middle regions, the bimetal and fixed contact elements are embedded positively in a form-stable base member made of injectable or castable synthetic electrically insulating material, which base member forms a part of the walls of the housing. At the region where the bimetal contact element protrudes from the base element to extend into the interior of the housing, it bears a weakened zone, e.g. a puched-out hole, as a bending zone being adjustable to a desired bend.

Description

Die Erfindung betrifft einen Überstromschutzschalter mit Bimetallauslösung zum Einstecken in Flachsicherungssockel mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen.The invention relates to an overcurrent protection switch with bimetallic release for insertion into a flat fuse base with the features specified in the preamble of claim 1.

Derartige Schalter sind aus DE-A 33 42 144 (= US-A-4 573 031) bekannt. Sie weisen sehr kleine Abmessungen auf und können daher als Ersatz von Flach-Schmelzsicherungen verwendet werden. Sie bestehen im wesentlichen aus einem Gehäuse, zwischen dessen Seitenwänden zwei Kontaktelemente gehalten sind. Bei diesen beiden Kontaktelementen handelt es sich um einen Bimetallkontakarm und einen Festkontaktarm, die als nebeneinanderliegende, jeweils langestreckte, etwa flachquaderförmige Stanzteile ausgebildet sind. Die aus dem Gehäuse herausstehenden Enden der beiden Kontaktarme sind mit ihren Haupterstreckungsebenen gleichebig angeordnet. Im Bereich ihrer gehäuseinneren Freienden sind diese Haupterstreckungsebenen parallel beabstandet. Durch diesen seitlichen Versatz ist es möglich, daß die dazwischen angeordnete Bimetallschnappscheibe etwa in der Haupterstreckungsebene des Bimetallkontaktarmes liegt und gleichzeitig den Festkontaktarm überlappt. Die Schnappbewegung kann also zu beiden Seiten der Haupterstreckungsebene des Bimetallkontaktarmes stattfinden.Such switches are known from DE-A 33 42 144 (= US-A-4 573 031). They have very small dimensions and can therefore be used as a replacement for flat fuses. They essentially consist of a housing, between the side walls of which two contact elements are held. These two contact elements are a bimetallic contact arm and a fixed contact arm, which are formed as adjacent, elongated, approximately flat cuboid stamped parts. The ends of the two contact arms protruding from the housing are arranged with their main planes of extension at the same level. In the area of their free ends, these main extension planes are spaced apart in parallel. This lateral offset makes it possible for the bimetallic snap disk arranged in between to lie approximately in the main plane of extension of the bimetallic contact arm and, at the same time, to overlap the fixed contact arm. The snap movement can therefore take place on both sides of the main extension plane of the bimetal contact arm.

Am Freiende des Bimetallkontaktarmes ist die Bimetallschnappscheibe einseitig befestigt. Sie erstreckt sich quer zur Einsteckrichtung der Kontaktarme und überlappt mit ihrem Befestigungsende das gegenüberliegende Schwenkende des Freiendes des Festkontaktarmes. Mit ihrem am Schwenkende angebrachten Bimetallkontakt liegt die Bimetallschnappscheibe am Festkontakt in nicht erhitzter Ruhestellung und Vorspannung an.At the free end of the bimetal contact arm, the bimetal snap disk is attached on one side. It stretches transverse to the direction of insertion of the contact arms and overlaps with their fastening end the opposite pivot end of the free end of the fixed contact arm. With its bimetallic contact attached to the swivel end, the bimetallic snap disc rests on the fixed contact in the unheated rest position and pretension.

Nachteilig an den bekannten derartigen Überstromschutzschaltern ist, daß die beiden Kontaktarme etwa gleichebig durch die Teilfuge zwischen den beiden Gehäuse-Halbschalen hindurchgeführt sind, aus denen das Schaltergehäuse gebildet ist. Die Kontaktarme liegen dabei in speziellen Formausnehmungen der Gehäuse-Halbschalen ein und werden beispielsweise durch eine Stift-Loch-Verbindung fixiert. Die Starrheit diese Fixierung ist jedoch nicht sehr groß und stabilisiert nicht ausreichend die relative Lage der beiden Kontaktarme zueinander. Durch die relativ hohen Fertigungstoleranzen und die zweiteilige Ausbildung des Gehäuses ist eine gegenseitige Verschiebung der Kontaktarme leicht möglich. Dadurch wird die Auslösecharakteristik eines derartigen Überstromschutzschalters stark beeinflußt. In der Praxis bedeutet dies eine-hohe Ausschußrate und eine relativ breite Streuung des Auslösezeitpunktes.A disadvantage of the known overcurrent protection switches of this type is that the two contact arms are guided approximately equally through the parting joint between the two housing half-shells from which the switch housing is formed. The contact arms are located in special recesses in the housing half-shells and are fixed, for example, by a pin-hole connection. However, the rigidity of this fixation is not very great and does not sufficiently stabilize the relative position of the two contact arms to one another. Due to the relatively high manufacturing tolerances and the two-part design of the housing, a mutual displacement of the contact arms is easily possible. As a result, the tripping characteristic of such an overcurrent protection switch is greatly influenced. In practice, this means a high reject rate and a relatively wide spread of the triggering time.

Der Erfindung liegt die Aufgabe zugrunde, die Auslösecharakteristik derartiger Schalter in engeren Toleranzbereichen zu halten und den Schalter nach dem Zusammenbau in seinen wesentlichen Funktionselementen einfach justierbar zu machen.The invention has for its object to keep the tripping characteristic of such switches within narrow tolerance ranges and to make the switch in its essential functional elements easily adjustable after assembly.

Diese Aufgabe wird gemäß den kennzeichnenden Merkmalen des Anspruches 1 dadurch gelöst, daß Bimetall- und Festkontaktarm mit ihrem Mittenbereich formschlüssig in einem aus formbeständigen, spritz- oder gießbaren Kunststoffisoliermaterial gefertigten Sockel eingebettet sind und daß der Bimetallkontaktarm an seiner gehäuseinneren Austrittsstelle aus dem Sockel eine Schwachstelle als Justier-Sollbiegestelle aufweist. Mit dieser Konstruktion ist einerseits gewährleistet, daß Bimetall- und Festkontaktarm unverrückbar gegeneinander fixiert sind. Dies ist ein wichtiges Kriterium dafür, daß eine spezielle Auslösecharakteristik auch während der gesamten Betriebszeit des Schalters eingehalten wird. Andererseits kann der Bimetallkontaktarm im Bereich der Schwachstelle durch eine entsprechende Justier-Vorrichtung einfach gebogen werden. Dadurch ändern sich der Abstand zwischen Bimetallkontakt und Festkontakt und somit die Vorspannung, mit der die Bimetallschnappscheibe am Festkontakt anliegt. Es ist also beim erfindungsgemäßen Schalter mit einfachen Mitteln möglich, den Soll-Toleranzbereich seiner Auslösecharakteristik nachträglich zu justieren und über die gesamte Betriebsdauer sicher beizubehalten. Da die Schwachstelle des Bimetallkontaktarmes an dessen Austrittsstelle aus dem Sockel liegt, ist ein größtmöglicher Hebelarm für eine Justierverschiebung des Kontaktarmfreiendes gegeben. Diese kann somit besonders fein dosiert durchgeführt werden. Nicht zuletzt ist der erfindungsgemäße Schutzschalter mechanisch besonders stabil.This object is achieved in accordance with the characterizing features of claim 1 in that the bimetallic and fixed contact arm with its central region in a form-fitting manner from a dimensionally stable, sprayable or pourable Plastic insulating material manufactured base are embedded and that the bimetallic contact arm has a weak point at its interior exit point from the base as a desired adjustment bending point. This construction ensures on the one hand that the bimetal and fixed contact arms are immovably fixed against each other. This is an important criterion for ensuring that a special tripping characteristic is maintained during the entire operating time of the switch. On the other hand, the bimetal contact arm can be easily bent in the area of the weak point by means of an appropriate adjusting device. This changes the distance between the bimetallic contact and the fixed contact and thus the preload with which the bimetallic snap disk is in contact with the fixed contact. With the switch according to the invention it is therefore possible with simple means to subsequently adjust the target tolerance range of its tripping characteristic and to maintain it reliably over the entire operating time. Since the weak point of the bimetallic contact arm lies at its point of exit from the base, the greatest possible lever arm is provided for an adjustment displacement of the contact arm end. This can therefore be carried out in a particularly fine dosage. Last but not least, the circuit breaker according to the invention is particularly mechanically stable.

Diese Stabilität wird durch das kennzeichnende Merkmal des Anspruches 2 weiter verbessert. Die einmal justierte und dadurch eingestellte Auslösecharakteristik kann durch die normalen Beanspruchungen bei der Anwendung des Schalters quasi nicht verändert werden. Durch das Kennzeichnungsmerkmal des Anspruches 3 ist es zudem unmöglich, daß der Festkontaktarm gegenüber dem Sockel längsaxial verschoben wird. Dem gleichen Zweck dient die Weiterbildung gemäß Anspruch 4. Auch der Bimetallkontaktarm ist durch seine Verschmälerung in Axialrichtung unverrückbar im Sockelmaterial festgehalten.This stability is further improved by the characterizing feature of claim 2. The tripping characteristic, once adjusted and thus set, can practically not be changed by the normal stresses when using the switch. Due to the characterizing feature of claim 3, it is also impossible that the fixed contact arm is displaced longitudinally axially relative to the base. Serves the same purpose the development according to claim 4. The bimetal contact arm is immovably held in the base material by its narrowing in the axial direction.

Gemäß Anspruch 5 handelt es sich bei der Schwachstelle am Bimetall kontaktarm um ein etwa senkrecht zu dessen Haupterstreckungsebene verlaufendes Stanzloch. Damit kann die Justier-Sollbiegestelle im gleichen Arbeitsgang wie die Fertigung des Stanzteiles selbst eingebracht und eine Torsion des Freiendes des Bimetallkontaktarmes um seine Längsachse beim Justiervorgang vermieden werden.According to claim 5, the weak point on the bimetal contact arm is an approximately perpendicular to its main extension plane punch hole. In this way, the desired adjustment bending point can be introduced in the same operation as the production of the stamped part itself and torsion of the free end of the bimetal contact arm about its longitudinal axis can be avoided during the adjustment process.

Durch eine Anordnung des Stanzloches gemäß Anspruch 6 wird die Justier-Sollbiegestelle noch genauer festgelegt und der Justiervorgang noch besser reproduzierbar. Die bereits grundsätzlich durch die Schwachstelle vorhandene Neigung des Bimetall kontaktarmes, sich an der Schwachstelle selbst zu biegen, wird noch dadurch verstärkt, daß genau an der Schwachstelle quasi der Drehpunkt des als einarmiger Hebel wirkenden Freiendes des Bimetallkontaktarmes liegt.By arranging the punched hole according to claim 6, the adjustment target bending point is determined more precisely and the adjustment process is even more reproducible. The tendency of the bimetal contact arm, which already exists fundamentally due to the weak point, to bend itself at the weak point, is further reinforced by the fact that the fulcrum of the free end of the bimetal contact arm, which acts as a one-armed lever, is located at the weak point.

Durch das Kennzeichnungsmerkmal des Anspruches 7 wird die Einbettung des Bimetallkontaktarmes in das Sockelmaterial und damit dessen Stabilität weiter verbessert. Das Stanzloch ist nämlich teilweise von Sockelmaterial durchsetzt, wodurch eine längsaxiale Verschiebung des Bimetallkontaktarmes gegenüber dem Sockel wirkungsvoll unterbunden ist.The embedding of the bimetallic contact arm in the base material and thus its stability is further improved by the characterizing feature of claim 7. The punching hole is partially penetrated by base material, which effectively prevents a longitudinal axial displacement of the bimetal contact arm relative to the base.

Durch die Ausführungsform der Schwachstelle nach dem Kennzeichnungsmerkmal des Anspruches 8 ist es in einfacher Weise möglich, den Bimetallkontaktarm nicht nur senkrecht zu seiner Haupterstreckungsebene einfach zu biegen, sondern noch zusätzlich zu tordieren, falls dies für die zutreffende Justierung notwendig ist. Durch das Kennzeichnungsmerkmal des Anspruches 9 läßt sich der Schalter nach der Erfindung besonders raumsparend herstellen. Er eignet sich dadurch auch als Ersatz für einfache Flach-Schmelzsicherungen. Der Sockel übernimmt die zusätzliche Funktion eines Wandteiles des Schaltergehäuses.Due to the embodiment of the weak point according to the characterizing feature of claim 8, it is possible in a simple manner to simply close the bimetallic contact arm not only perpendicular to its main extension plane bend, but also to twist if this is necessary for the correct adjustment. Due to the characterizing feature of claim 9, the switch according to the invention can be made particularly space-saving. It is therefore also suitable as a replacement for simple flat fuses. The base takes on the additional function of a wall part of the switch housing.

Der durch den Druckknopf 1 betätigbare Überstromschutzschalter weist ein aus Kappe 2 und Sockel 3 zusammengesetztes Gehäuse auf. Beide Teile sind aus einem spritz- oder gießbaren, elektrisch isolierenden Material gefertigt. Eingebettet in den etwa quaderförmigen Sockel 3 sind der Bimetallkontaktarm 4 und der Festkontaktarm 5. Beide Arme 4,5 bestehen aus einem langgestreckten, flachquaderförmigen metallischen Stanzteil. Die Haupterstreckungsebenen der aus dem Gehäuse herausgeführten Einsteckenden 6,7 der Kontaktarme 4,5 sind gleichebig. Letztere liegen parallel nebeneinander und sind als flache Steckzungen ausgebildet. In ihrem Mittenbereich 8 weisen die beiden Kontaktarme 4,5 jeweils eine entgegengesetzt nach außen gerichtete Abbiegung 9,10 auf (Fig. 5). Die Haupterstreckungsebenen der gehäuseinneren Freienden 11,12 der Kontaktarme 4,5 liegen somit parallel in einem Abstand 19 zueinander. Die Abbiegung 9 des Bimetallkontaktarmes 4 liegt dabei im Gehäuseinnenraum, während die Abbiegung 10 des Festkontaktarmes 5 im vom Sockelmaterial umspritzten Bereich angeordnet ist.The overcurrent protection switch which can be actuated by the push button 1 has a housing composed of a cap 2 and a base 3. Both parts are made of a sprayable or pourable, electrically insulating material. The bimetallic contact arm 4 and the fixed contact arm 5 are embedded in the approximately cuboid base 3. Both arms 4, 5 consist of an elongated, flat cuboid metal stamped part. The main planes of extension of the insertion ends 6, 7 of the contact arms 4, 5 leading out of the housing are the same. The latter are parallel to each other and are designed as flat tongues. In their central area 8, the two contact arms 4, 5 each have an opposite outward bend 9, 10 (FIG. 5). The main planes of extension of the inner free ends 11, 12 of the contact arms 4, 5 are thus parallel to each other at a distance 19. The bend 9 of the bimetallic contact arm 4 lies in the interior of the housing, while the bend 10 of the fixed contact arm 5 is arranged in the area encapsulated by the base material.

Am gehäuseinneren Freiende 11 des Bimetallkontaktarmes 4 ist eine oval geformte Bimetallschnappscheibe 13 einseitig befestigt. Sie erstreckt sich quer zur Richtung der Kontaktarme 4,5 in Richtung zum Festkontaktarm 5. Ihr Schwenkende 14 weist den Bimetallkontakt 15 auf, der damit beweglich ist. Diesem gegenüber liegt der am Freiende 12 des Festkontaktarmes 5 angebrachte Festkontakt 16 des Überstromschutzschalters. Das Schwenkende 14 überlappt das Freiende 12 des Festkontaktarmes 5 und liegt in Ruhestellung des Schalters mit seinem Bimetallkontakt 15 am Festkontakt 16 unter Vorspannung an.An oval-shaped bimetal snap disk 13 is fastened on one side to the free end 11 of the bimetal contact arm 4 inside the housing. It extends transversely to the direction of the contact arms 4, 5 in the direction of the fixed contact arm 5. Its swiveling end 14 has the bimetallic contact 15, which is thus movable. This is opposite the fixed contact 16 of the overcurrent protection switch attached to the free end 12 of the fixed contact arm 5. The swivel end 14 overlaps the free end 12 of the fixed contact arm 5 and is in the rest position of the switch with its bimetallic contact 15 on the fixed contact 16 under prestress.

An seiner gehäuseinneren Austrittsstelle 17 aus dem Sockel 3 weist der Bimetallkontaktarm 4 das Stanzloch 18 auf, das ihn senkrecht zu seiner Haupterstreckungsrichtung durchsetzt. Dadurch ist eine Schwachstelle geschaffen, die als Justier-Sollbiegestelle fungiert, falls sich eine Nachjustierung als erforderlich erweist. Bei der modifizierten Form der Schwachstelle gemäß Fig. 6 ist diese durch zwei seitliche Einkerbungen 29 in Form je eines Halbloches gebildet.At its housing-internal exit point 17 from the base 3, the bimetallic contact arm 4 has the punched hole 18, which penetrates it perpendicularly to its main direction of extension. This creates a weak point, which acts as an adjustment target bending point if readjustment proves to be necessary. In the modified form of the weak point according to FIG. 6, it is formed by two lateral notches 29 in the form of a half-hole each.

In seinem vom Sockelmaterial umgebenen Bereich weist der Bimetallkontaktarm 4 die stufenförmige Verschmäle rung 21 auf (Fig. 5), die genau wirkend wie die Abbiegung des Festkontaktarmes 5 ein Verschieben des Kontaktarmes innerhalb der Einbettung verhindert.In its area surrounded by the base material, the bimetallic contact arm 4 has the step-like narrowing 21 (FIG. 5), which acts exactly like the bend of the fixed contact arm 5 to prevent the contact arm from moving within the embedding.

Wie aus den Fig. 1 und 3 ersichtlich, befindet sich das kreisrunde Stanzloch 18 genau an der Austrittsstelle 17 des Bimetallkontaktarmes 4 aus dem Sockel 3. Dadurch ist das Stanzloch 18 teilweise von Sockelmaterial durchsetzt. Es ergibt sich ein zusätzlicher Fixierungseffekt für den Bimetallkontaktarm 4 sowie einen sauberen Drehpunkt für dessen Freiende 11 beim Justiervorgang.As can be seen from FIGS. 1 and 3, the circular punched hole 18 is located exactly at the exit point 17 of the bimetal contact arm 4 from the base 3. As a result, the punched hole 18 is partially penetrated by base material. There is an additional fixation effect for the bimetal contact arm 4 and a clean pivot point for its free end 11 during the adjustment process.

Räumlich zwischen den beiden Freienden 11,12 von Bimetall-4 und Festkontaktarm 5 ist der in Einsteckrichtung 22 verschiebbare Druckknopf 1 zur Einschaltung des Schalters angeordnet. Dieser ist im wesentlichen L-förmig ausgebildet, wobei das Freiende seines L-Vertikalschenkels 23 eine Ausnehmung 24 in der Decke 25 der Kappe 2 durchgreift. Im Basisbereich dieses Schenkels 23 ist eine ebenfalls in Einsteckrichtung 22 verlaufende Sackbohrung 26 zur Aufnahme der Druckfeder 27 vorgesehen. Diese stützt sich an der Oberseite des Sockels 3 ab und beaufschlagt den Druckknopf 1 entgegen der Einsteckrichtung 22. Der L-Horizontalschenkel 28 des Druckknopfes 1 ist gegen den Druck der Druckfeder 27 aus dem Zwischenraum zwischen den Kontakten 15,16 ausschiebbar und bewirkt dabei eine Kontaktschließung von Hand.Spatially between the two free ends 11, 12 of the bimetal 4 and the fixed contact arm 5, the push button 1, which can be moved in the insertion direction 22, is arranged to switch on the switch. This is essentially L-shaped, the free end of its L-vertical leg 23 reaching through a recess 24 in the ceiling 25 of the cap 2. In the base region of this leg 23, a blind bore 26, which also extends in the insertion direction 22, is provided for receiving the compression spring 27. This is supported on the top of the base 3 and acts on the push button 1 against the insertion direction 22. The L-horizontal leg 28 of the push button 1 can be pushed out against the pressure of the compression spring 27 from the space between the contacts 15, 16 and thereby causes a contact closure by hand.
