Description

Die Erfindung bezieht sich auf eine Überspannungsschutzsteckdose mit einem in ein Leergehäuse, wie eine Leerdose, einsetzbaren Sockel mit vorgegebener Einbautiefe und mit Bauelementen für die Überspannungsschutzeinrichtung, die im Doseninnenraum zwischen dem eingesetzten Sockel und der Wandung des Leergehäuses angeordnet sind.The invention relates to a surge protection socket with one in an empty case, like an empty can, usable base with specified installation depth and with Components for the surge protection device, which in Can interior between the base used and the Wall of the empty housing are arranged.

Eine solche Überspannungsschutzsteckdose ist aus der deutschen Patentschrift DE 40 01 576 C2 bekannt. Die Bauteile der Überspannungsschutzeinrichtung sind hier in einem Freiraum am Sockel untergebracht, der an der Rückseite des Sokkels eingesenkt ist. Damit die für den Sockel der Überspannungsschutzsteckdose genormte Einbautiefe nicht überschritten wird, was allein schon eine Miniaturisierung der Bauelemente bedingt, muß ein Spezialsockel vorgesehen werden, der gegenüber dem Sockel einer Standardsteckdose ein verringertes Volumen hat.Such a surge protection socket is from the German Patent specification DE 40 01 576 C2 known. The components the surge protection device are here in a free space on the base, the one on the back of the base is sunk. So that for the base of the surge protection socket standardized installation depth not exceeded is what alone is a miniaturization of the components conditional, a special base must be provided, which is reduced compared to the base of a standard socket Volume.

Ferner geht aus dem deutschen Gebrauchsmuster DE 296 01 440 U1 eine Steckdose mit Modulen für Zusatzfunktionen, insbesondere für eine Überspannungsschutzeinrichtung, hervor, bei der diese Module seitlich neben dem aus Isolierstoff bestehenden Sockel angeordnet sind. Bei dieser Lösung geht es darum, großvolumige Module seitlich neben dem Sockel unterbringen zu können, weshalb auch hier der Sockel eine Spezialausführung ist, die gegenüber einem Standardsockel asymmetrisch ausgeführt ist. Furthermore, the German utility model DE 296 01 440 U1 a socket with modules for additional functions, in particular for a surge protection device, where these modules are next to the one made of insulating material existing base are arranged. This solution works it is about accommodating large-volume modules on the side next to the base to be able to, which is why the base here is a Special version is that compared to a standard base is asymmetrical.

An sich bietet bei der möglichen Miniaturisierung eine Standardsteckdose im Innenraum an der Umfangseite des Sokkels genügend Platz, um die Bauteile der Überspannungsschutzeinrichtung unterbringen zu können, wie aus dem deutschen Gebrauchsmuster 295 07 448 hervorgeht. Das Problem liegt jedoch darin, diese Bauteile zum einen in ihrer Lage zueinander und zum anderen in ihrer Lage relativ zum Sockel der Steckdose sicher zu fixieren. Bei der letztgenannten, bekannten Steckdose ist hierzu ein zusätzliches, den Sockel umgebendes Isolierstoffgehäuse vorgesehen, an dessen Innenwand Haltevorrichtungen für eine Platine und für die von dieser Platine getragenen Bauteile vorgesehen sind. An der nach oben offenen Öffnung des genannten Isolierstoffgehäuses sind Rastmittel vorgesehen, die hier eine Befestigung der Überspannungsschutzeinrichtung nur an solchen Steckdosen ermöglicht, die mit einem Tragring versehen sind.In itself, with the possible miniaturization Standard socket in the interior on the circumferential side of the base enough space to hold the components of the surge protective device to be able to accommodate, as from the German Utility model 295 07 448 emerges. The problem lies, however, in the location of these components to each other and to the other in their position relative to the base the socket securely. In the latter, Known socket is an additional, the base surrounding insulating housing provided on the inner wall Holding devices for a circuit board and for that of this board supported components are provided. At the open opening of the above-mentioned insulating material housing locking means are provided, which are attached here the surge protection device only at such sockets enables that are provided with a support ring.

Der Erfindung liegt die Aufgabe zugrunde, eine Überspannungsschutzsteckdose der eingangs genannten Art zu schaffen, die als Standardsteckdose ausgeführt ist und bei der eine einwandfreie Fixierung der Bauteile der Überspannungsschutzeinrichtung am Sockel besteht.The invention has for its object an overvoltage protection socket of the type mentioned at the beginning, which is designed as a standard socket and at the a perfect fixation of the components of the surge protection device on the base.

Diese Aufgabe wird bei einer Überspannungsschutzsteckdose der gattungsgemäßen Art nach der Erfindung dadurch gelöst, daß die Überspannungsschutz-Bauteile an der Innenseite eines biegsamen Gurtes angeordnet sind und dieser Gurt um den Umfang des Sockels herumgelegt und daran befestigt ist.This task is done with a surge protector of the generic type according to the invention, that the surge protection components on the inside of a flexible belt are arranged and this belt around the Circumference of the base and is attached to it.

Für die Erfindung ist wesentlich, daß die Bauteile der Überspannungsschutzeinrichtung auf dem Gurt fixiert sind, der aus einem biegsamen Material besteht, das sich in an die Umfangsseite des Sockels der Steckdose angeschmiegter Lage festlegen läßt, wobei die Bauteile der Überspannungsschutzeinrichtung so auf dem Gurt positioniert werden können, daß der im Doseninnenraum zur Verfügung stehende Platz an der Umfangsseite des Sockels einer Standardsteckdose optimal für die Unterbringung dieser Bauteile genutzt werden kann.It is essential for the invention that the components of the Surge protection device are fixed on the belt which is made of a flexible material that fits in the circumferential side of the socket of the socket nestled Location can be determined, the components of the surge protective device can be positioned on the belt that the space available in the interior of the can optimal on the circumferential side of the base of a standard socket can be used to accommodate these components can.

In vorteilhafter Ausgestaltung der Erfindung können in den Gurt Leiterbahnen integriert sein, die der Verschaltung der Bauteile der Überspannungsschutzeinrichtung dienen. Zusätzlich dazu oder unabhängig davon kann auf den Gurt auch noch eine Leiterplatte aufgebracht sein, die entsprechend der Biegefähigkeit des Gurtes ebenfalls biegsam ist.In an advantageous embodiment of the invention, the Belt conductor tracks can be integrated, the interconnection of the Components of the surge protection device are used. In addition in addition to or independently of this, the strap can also be used a printed circuit board can be applied according to the Bendability of the belt is also flexible.

Zur mechanischen Befestigung des Gurtes ist es weiter von Vorteil, wenn an den beiden Gurtenden über die Bauteile der Überspannungsschutzeinrichtung vorstehende Befestigungslaschen angeordnet sind, die an den Umfangsseiten des Sockels festgelegt sind. Insbesondere können diese Befestigungslaschen an der Umfangsseite des Sockels verklebt werden. Des weiteren können an der der Unterseite des Sockels benachbarten Längsseite des Gurtes zusätzliche Klemmlaschen vorgesehen werden, die an dem Gurt abgewinkelt vorstehen und zweckmäßig einstückig an den Gurt angeformt sind. In der Einbaulage untergreifen diese Klemmlaschen den Sockel.For mechanical fastening of the belt, it is further from Advantage if the two belt ends over the components of the Surge protection device protruding mounting tabs are arranged on the peripheral sides of the base are set. In particular, these mounting tabs be glued to the circumferential side of the base. Of further can be adjacent to the bottom of the base Additional clamping tabs are provided on the long side of the belt that protrude from the belt and are expediently integrally formed on the belt. In the In the installation position, these clamping lugs reach under the base.

Der Gurt besteht aus einem solchem Material, das zum einen die Tragfähigkeit für die daran befestigten Bauteile sicherstellt. Grundsätzlich kann der Gurt durchgehend biegsam sein, in der Regel genügt es jedoch, ihn lediglich an bestimmten Stellen biegbar auszuführen. So kann in eingebautem Zustand der Gurt eine Lage einnehmen, in der im wesentlichen ebene Abschnitte aneinander übereck anschließen, wobei lediglich im Eckbereich der Gurt als Filmscharnier ausgebildet ist oder aufgrund seines Materials ein Filmscharnier bildet. So kann sich der Gurt in der Einbaulage über einen Polygonabschnitt hinweg erstrecken, um beispielsweise in etwa die Form eines halben Sechsecks im wesentlichen einzunehmen. Insbesondere in dieser Ausführung kann der Gurt in die Gehäuse der Bauteile der Überspannungseinrichtung integriert sein, wo er durch Wandungsabschnitte dieser Gehäuse gebildet sein kann, wobei in diesem Falle die den Gurt insgesamt bildenden Gehäuse oder Gehäuseteile mittels der Filmscharniere gelenkig miteinander verbunden sind.The belt is made of such a material, on the one hand ensures the load-bearing capacity for the components attached to it. Basically, the belt can be flexible throughout , it is usually sufficient to use it only on certain Make bendable places. So in built Condition of the belt occupy a position in which essentially Connect the flat sections to each other in a corner, whereby only formed in the corner area of the belt as a film hinge is or because of its material a film hinge forms. So the belt can over in the installation position extend a polygon section, for example roughly the shape of a half hexagon to take. Especially in this version, the Belt in the housing of the components of the surge device be integrated where it through wall sections of this Housing can be formed, in which case the Belt overall forming housing or housing parts by means of the film hinges are hinged together.

Im einzelnen erkennt man in Figur 1 ein Leergehäuse 1, bei dem es sich entweder um eine unter Putz anzubringende Leerdose oder um ein Gehäuse handelt, das in sogenannter Aufputzmontage auf einer Wand anzuordnen ist. In das Leergehäuse 1 ist ein aus Isolierstoff bestehender Sockel 2 einfügbar, der mechanisch mit dem Leergehäuse 1 mittels eines schematisch wiedergegebenen Tragringes 3 verbunden wird. Der Sockel 2 ist Teil einer Standard-Schutzkontaktsteckdose und weist die üblichen Einstecköffnungen 4 für Steckerstifte und die mit einem Erdleiter zu verbindenden Schutzkontakte 5 auf.In detail, an empty housing 1 can be seen in FIG which is either an empty box to be flush-mounted or is a housing that is known as surface mounting to be placed on a wall. In the empty housing 1, a base 2 made of insulating material can be inserted, the mechanically with the empty housing 1 by means of a schematically shown support ring 3 is connected. The base 2 is part of a standard earthed socket and has the usual insertion openings 4 for connector pins and the protective contacts to be connected to an earth conductor 5 on.

Des weiteren ist die Steckdose mit einer Überspannungsschutzeinrichtung ausgestattet. Hierzu gehören Bauteile 6 bis 8, nämlich ein Varistor 7, ein Akustikmelder 6 und ein Gasableiter 8. Die Besonderheit der Steckdose liegt darin, daß diese Bauteile 6 bis 8 der Überspannungsschutzeinrichtung auf einem Gurt 9 angeordnet sind.The socket is also equipped with a surge protection device fitted. This includes components 6 to 8, namely a varistor 7, an acoustic detector 6 and a Gas arrester 8. The special feature of the socket is that that these components 6 to 8 of the surge protective device are arranged on a belt 9.

Einzelheiten dieses Gurtes 9 erkennt man in Figur 2. Der Gurt hat zumindest zwei innere Knickstellen, und wenigstens an diesen Knickstellen ist der Gurt 9 biegsam. Deshalb hat der Gurt an diesen Knickstellen Filmscharniere 10, die durch den Gurt 9 selbst gebildet sein können, der im übrigen durch die daran angebrachten Bauteile 6 bis 8 versteift ist. Mit seinen beiden Enden steht der Gurt 9 über denjenigen Bereich relativ weit über, in welchem die Bauteile 6 bis 8 an dem Gurt 9 befestigt sind. Hier bildet der Gurt beidendig Befestigungslaschen 11, über die primär die Festlegung des Gurtes 9 an der Umfangsseite des Sockels 2 der Steckdose erfolgt, wie Figur 1 deutlich macht. Die Biegsam keit des Gurtes erlaubt es nämlich, ihn mitsamt der an seiner Innenseite angebrachten Bauteile 6 bis 8 der Überspannungsschutzeinrichtung um den Sockel 2 der Steckdose herum anzulegen, wodurch der Sockel 2 entlang eines Teils seines Umfanges von der Überspannungsschutzeinrichtung umgeben ist. Je nach der Umfangsform des Sockels 2 legt sich der Gurt entlang eines Abschnittes eines mehr oder weniger regelmäßigen Polygons, wovon allerdings die Befestigungslaschen 11 dann abweichen, wenn wie beim dargestellten Ausführungsbeispiel, die Befestigungsstellen am Sockelumfang für die Befestigungslaschen 11 stärker zerklüftet sind. Hier werden die Befestigungslaschen 11 des Gurtes 9 dauerhaft festgelegt, insbesondere verklebt oder geklemmt. In der Einbaulage finden die an der Innenseite des Gurtes 9 befindlichen Bauteile 6 bis 8 der Überspannungsschutzeinrichtung genügend Platz, denn der Sockel 2 weist an seiner Umfangsseite eingebuchtete Freiräume 13 auf, in welche die Bauteile 6 bis 8 teilweise eintauchen können. Die Kontur des Gurtes 9 ist derart gestaltet, daß die Bauteile 6 bis 8 der Überspannungsschutzeinrichtung gegen mechanische Einwirkungen und gegen Berührungen geschützt sind.Details of this belt 9 can be seen in Figure 2. The Belt has at least two internal kinks, and at least the belt 9 is flexible at these kinks. That's why the belt at these kinks film hinges 10, the can be formed by the belt 9 itself, the rest stiffened by the components 6 to 8 attached to it is. With its two ends, the belt 9 is above the one Range relatively far above in which the components 6 to 8 are attached to the belt 9. Here is the belt fastening tabs 11 at both ends, via which the primary fixing of the belt 9 on the circumferential side of the base 2 of the Socket takes place, as Figure 1 clearly shows. The pliable The fact that the belt is fastened allows it to be attached to it along with it Components 6 to 8 of the overvoltage protection device attached to the inside around the socket 2 of the socket to create, whereby the base 2 along part of its Surrounded by the surge protection device is. Depending on the circumferential shape of the base 2, the Strap along a section of a more or less regular Polygons, of which, however, the fastening tabs 11 then deviate if, as in the exemplary embodiment shown, the fastening points on the base circumference are more jagged for the mounting tabs 11. Here the fastening tabs 11 of the belt 9 become permanent fixed, especially glued or clamped. In the installation position can be found on the inside of the belt 9 located components 6 to 8 of the surge protective device enough space, because the base 2 points to it On the peripheral side indented spaces 13, in which the Components 6 to 8 can be partially immersed. The contour of the belt 9 is designed such that the components 6 to 8th the surge protection device against mechanical influences and are protected against touch.

Die Bauteile 6 bis 8 und die weiter benötigten elektrischen Elemente der Überspannungsschutzeinrichtung sind miteinander elektrisch verschaltet, und hierzu können in den Gurt 9 selbst entsprechende Leiterbahnen integriert sein. In anderer Ausführung, wie in Figur 2 wiedergegeben ist, ist auf die Innenseite des Gurtes 9 eine Leiterplatte 14 aufgebracht, die ebenfalls biegsam ist, damit sie sich in der Einbaulage nicht von dem Gurt 9 ablösen kann. The components 6 to 8 and the further required electrical Elements of the surge protection device are interconnected electrically connected, and this can be done in the belt 9 even corresponding conductor tracks can be integrated. In others Execution as shown in Figure 2 is on the inside of the belt 9 has a circuit board 14 applied, which is also flexible so that it can be Installation position can not detach from the belt 9.

Figur 3 veranschaulicht, daß an der einen Längsseite des Gurtes 9, die in der Einbaulage benachbart der Rückseite des Sockels 2 der Steckdose angeordnet ist, Klemmlaschen 12 angesetzt oder angeformt sind, die zumindest in der Einbaulage rechtwinklig von dem Gurt 9 abstehen und den Sockel 2 der Steckdose untergreifen. So können diese Klemmlaschen 12 beispielsweise zwischen der Rückseite des Sockels 2 und einer rückwärtigen Wandung des Leergehäuses 1 verspannt werden. Um die gewünschten Biege- und Klemmeigenschaften des Gurtes 9 zu erzielen, besteht er zweckmäßig aus einem geeigneten, elektrisch isolierenden Kunststoffmaterial.Figure 3 illustrates that on one long side of the Belt 9, which is in the installation position adjacent to the back the socket 2 of the socket is arranged, clamping tabs 12 are attached or molded, at least in the installed position protrude at right angles from the belt 9 and the base 2 reach under the socket. So these clamping tabs 12 for example between the back of the base 2 and one rear wall of the empty housing 1 are clamped. To the desired bending and clamping properties of the To achieve belt 9, it suitably consists of a suitable electrically insulating plastic material.

Fig. 3 zeigt weiter, daß die Bauteile 6-8 Gehäuse 15, 16 und 17 haben, in die der Gurt 9 entweder integriert ist oder die Teile dieses Gurtes 9 bilden. Im letzteren Falle werden die Gehäuse 15, 16 und 17 durch die Filmscharniere 10 des Gurtes 9 miteinander gelenkig verbunden.Fig. 3 further shows that the components 6-8 housing 15, 16th and 17, in which the belt 9 is either integrated or form the parts of this belt 9. In the latter case the housings 15, 16 and 17 through the film hinges 10 of the belt 9 hinged together.
