Description

Die Erfindung betrifft eine bauraumoptimierte Abtrennvorrichtung.The invention relates to a space-optimized separation device.

Hintergrund der ErfindungBackground of the invention

Elektrische Geräte sind auf elektrische Energie angewiesen. Elektrische Energie wird dabei häufig über ein Leitungsnetz zur Verfügung gestellt. Dabei kann es auf Grund von Fehlschaltungen, Netzstörungen, Blitzeinschlägen oder anderen Phänomenen zu Überspannungen kommen.Electrical devices rely on electrical energy. Electrical energy is often provided via a pipeline network. This can lead to overvoltages due to faulty circuits, power disturbances, lightning strikes or other phenomena.

Solche Überspannungen sind für angeschlossene elektrische Geräte (als auch für das Leitungsnetz) gefährlich. Sie können zu einer Funktionsstörung oder zu einer Schädigung bis hin zu einer totalen Zerstörung führen.Such overvoltages are dangerous for connected electrical devices (as well as for the line network). They can lead to a malfunction or damage to total destruction.

Daher werden viele elektrische Geräte (bzw. auch deren Leitungsnetz), sei es zum Schutz der Investition, sei es auf Grund normativer Anforderungen, mit einem Überspannungsschutz ausgestattet.Therefore, many electrical devices (or their line network), be it to protect the investment, be it due to normative requirements, equipped with an overvoltage protection.

Dieser Überspannungsschutz ist jedoch auch fehleranfällig, sei es durch ein Übermaß an abzuleitender Energie, sei es durch häufiges Ansprechen in Folge einer Überspannung. Solche Fehler können zu einer Zerstörung des Überspannungsschutzelementes, zu starker thermischer Erwärmung bis hin zu Brand als auch zu Rauchgasentwicklung führen, die potentiell gefährlich für Geräte und Personen in der Umgebung hiervon sind.However, this overvoltage protection is also susceptible to errors, be it by an excess of energy to be dissipated, be it by frequent response as a result of an overvoltage. Such failures can result in destruction of the overvoltage protection element, excessive thermal heating, fire, and flue gas evolution that are potentially hazardous to equipment and people in the vicinity thereof.

Tritt ein Fehler auf, so wird das entsprechende Überspannungsschutzelement mittels geeigneter Einrichtungen entweder abgetrennt und somit der Energiezufuhr unterbrochen, oder kurzgeschlossen, um eine zuvor angeordnete Leistungssicherung zum Abtrennen zu veranlassen.If an error occurs, the corresponding overvoltage protection element is either disconnected by means of suitable devices and thus the power supply interrupted or short-circuited to cause a previously arranged power fuse to disconnect.

Ein Beispiel einer Abtrenneinrichtung ist z.B. die aus DE 90 102 46 U1 bekannte Temperatursicherung, die einem Bauelement zugeordnet ist, um eine Abschaltung bei Erwärmung zu ermöglichen.An example of a separation device is for example the DE 90 102 46 U1 known thermal fuse associated with a device to enable shutdown when heated.

Allerdings ist aufgrund der begrenzten thermischen Ankopplungsmöglichkeit diese Anordnung für sehr schnelle Erwärmungsvorgänge nicht geeignet.However, due to the limited thermal coupling possibility, this arrangement is not suitable for very rapid heating operations.

Weitere Einrichtungen zum Abtrennen bzw. Kurzschließen sind aus den Patenten DE 42 41 311 der Anmelderin sowie der DE 699 04 274 T2 sowie dem US Patent US 6,430,019 beschrieben.Other devices for separating or shorting are from the patents DE 42 41 311 the applicant and the DE 699 04 274 T2 and the US patent US 6,430,019 described.

Die in den genannten Schriften beschrieben Lösungen basieren auf dem Prinzip, dass das zu überwachende Bauteil über ein Kontaktelement thermosensitiv - im Allgemeinen über eine Lötverbindung - angebunden wird. Das Kontaktelement ist vorgespannt montiert oder auf das Kontaktelement wirkt eine Kraft eines zweiten vorgespannten Elementes, z.B. einer Feder. Überschreitet die Federkraft die Haltekraft der thermosensitiven Kontaktstelle, z.B. Lötstelle, öffnet der Kontakt und das überwachte Bauteil wird abgeschaltet.The solutions described in the cited documents are based on the principle that the component to be monitored is thermosensitive via a contact element, generally via a solder connection. The contact element is preloaded or the force applied to the contact element is a second biased element, e.g. a spring. If the spring force exceeds the holding force of the thermosensitive pad, e.g. Solder, opens the contact and the monitored component is turned off.

Allerdings sind die bisherigen Anordnungen äußerst raumgreifend und aufwändig in der Herstellung.However, the previous arrangements are extremely bulky and expensive to manufacture.

Es wäre daher wünschenswert auch Lösungen angeben zu können, die bei geringen Baugrößen Verwendung finden können und/oder die kostengünstig hergestellt werden können.It would therefore be desirable to be able to specify solutions that can be used with small sizes and / or that can be produced inexpensively.

Zudem wäre es wünschenswert eine Vorrichtung angeben zu können, die auch für eine Vielzahl von zu überwachenden Bauelementen Verwendung finden könnte und/oder die kostengünstig hergestellt werden kannIn addition, it would be desirable to be able to specify a device which could also be used for a large number of components to be monitored and / or which can be produced inexpensively

Die Aufgabe wird gelöst durch eine Vorrichtung gemäß Anspruch 1. Weitere vorteilhafte Ausgestaltungen sind insbesondere Gegenstand der abhängigen Ansprüche.The object is achieved by a device according to claim 1. Further advantageous embodiments are in particular subject of the dependent claims.

Nachfolgend wird die Erfindung näher unter Bezug auf die Figuren erläutert. In diesen zeigt:

  • Fig. 1 eine erfindungsgemäße Abtrennvorrichtung in einem beispielhaften ersten Zustand in einem schematischen Querschnitt,
  • Fig. 2 die erfindungsgemäße Abtrennvorrichtung in einem beispielhaften zweiten Zustand in einem schematischen Querschnitt, und
  • Fig. 3 die erfindungsgemäße Abtrennvorrichtung in einem beispielhaften dritten Zustand in einem schematischen Querschnitt.
The invention will be explained in more detail with reference to the figures. In these shows:
  • Fig. 1 FIG. 2 shows a separating device according to the invention in an exemplary first state in a schematic cross section, FIG.
  • Fig. 2 the separating device according to the invention in an exemplary second state in a schematic cross section, and
  • Fig. 3 the separating device according to the invention in an exemplary third state in a schematic cross section.

In den Figuren ist eine beispielhafte bauraumoptimierte Abtrennvorrichtung 1 gemäß Ausführungsformen der Erfindung gezeigt. Dabei wird in den Darstellungen eine Anordnung mit zwei zu überwachenden Bauelementen EB1 und EB2 gezeigt, die Erfindung ist jedoch nicht hierauf beschränkt. D.h. die Funktionsprinzipien können auch mit nur einem zu überwachenden elektronischen Bauelement EB1 als auch mit mehr als zwei zu überwachenden Bauelementen EB1, EB2 verwirklicht werden.In the figures, an exemplary space-optimized separation device 1 according to embodiments of the invention is shown. In this case, an arrangement with two components to be monitored EB 1 and EB 2 is shown in the illustrations, but the invention is not limited thereto. That is, the functional principles can also be implemented with only one electronic component EB 1 to be monitored and with more than two components EB 1 , EB 2 to be monitored.

Die zu überwachenden elektronischen Bauelemente EB1, EB2 sind auf einem Träger P - beispielsweise eine Platine - mit einer thermisch erweichbaren Fixierung befestigt. Die thermische Fixierung kann dabei auch noch andere Funktionen übernehmen, wie z.B. die Bereitstellung einer elektrischen Verbindung.The electronic components to be monitored EB 1 , EB 2 are on a support P - for example, a board - fixed with a thermally softenable fixation. The thermal fixation can also take on other functions, such as the provision of an electrical connection.

An jedem der elektronischen Bauelement EB1, EB2 ist ein Kraftspeicher D1, D2 angeordnet. D.h. an dem elektronischen Bauelement EB1 ist Kraftspeicher D1 angeordnet während an dem elektronischen Bauelement EB2 Kraftspeicher D2 angeordnet ist.At each of the electronic component EB 1 , EB 2 , a force storage D 1 , D 2 is arranged. That is, at the electronic component EB 1 energy storage D 1 is arranged while on the electronic component EB 2 energy storage D 2 is arranged.

Wenn nun eine thermisch erweichbare Fixierung an einem elektronischen Bauelement erweicht, wird unter Freiwerden der gespeicherten Kraft aus dem zugehörigen Kraftspeicher das zugehörige elektronische Bauelement im Wesentlichen parallel zum Träger P verschoben und dabei das zugehörige elektronische Bauelement abgetrennt.If a thermally softenable fixation on an electronic component softens, the associated electronic component is displaced substantially parallel to the carrier P while the stored force is released from the associated energy store, thereby disconnecting the associated electronic component.

Während in Figur 1 hierzu der Anfangszustand, d.h. der nicht ausgelöste Zustand gezeigt ist, ist in Figur 2 das zu überwachende elektronische Bauelement EB1 ausgelöst. D.h. die thermische Fixierung zum Träger P ist erweicht und das zu überwachende elektronische Bauelement EB1 wurde mittels der Kraft aus dem Kraftspeicher D1 parallel zum Träger verschoben. Dabei wurde das zu überwachende elektronische Bauelement EB1 zugleich von seinen elektrischen Anschlüssen (nicht dargestellt) abgetrennt. In Figur 3 wiederum ist wohl das zu überwachende elektronische Bauelement EB1 als auch das zu überwachende elektronische Bauelement EB2 ausgelöst. Dabei wurde das zu überwachende elektronische Bauelement EB1 zugleich von seinen elektrischen Anschlüssen (nicht dargestellt) abgetrennt. Ebenso wurde das zu überwachende elektronische Bauelement EB2 zugleich von seinen elektrischen Anschlüssen (nicht dargestellt) abgetrennt.While in FIG. 1 For this purpose, the initial state, ie the untripped state is shown, is in FIG. 2 triggered to be monitored electronic component EB 1 . That is, the thermal fixation to the carrier P is softened and the electronic component to be monitored EB 1 was moved by means of the force from the energy storage device D1 parallel to the carrier. In this case, the electronic component to be monitored EB 1 was at the same time separated from its electrical connections (not shown). In FIG. 3 in turn, the electronic component EB 1 to be monitored and the electronic component EB 2 to be monitored are triggered. In this case, the electronic component to be monitored EB 1 was at the same time separated from its electrical connections (not shown). Likewise, the electronic component EB 2 to be monitored was at the same time separated from its electrical connections (not shown).

Weiterhin weist die beispielhafte bauraumoptimierte Abtrennvorrichtung 1 noch ein mechanisches verschiebbares Anzeigemittel ANZ auf, wobei das mechanisch verschiebbare Anzeigemittel anzeigt, mindestens eines der zu überwachenden elektronischen Bauelemente abgetrennt wurde, wobei das mechanisch verschiebbare Anzeigemittel ANZ durch ein abtrennendes elektronisches Bauelement verschoben wird.Furthermore, the exemplary space-optimized separating device 1 still has a mechanical displaceable display means ANZ, wherein the mechanically displaceable display means indicates at least one of the electronic components to be monitored has been separated, wherein the mechanically displaceable display means ANZ is displaced by a separating electronic component.

Mit der oben beschriebenen Ausgestaltung ist es möglich eine bauraumoptimierte Abtrennvorrichtung bereitzustellen, die zudem kostengünstig realisiert werden kann. Die bauraumoptimierte Abtrennvorrichtung 1 zeigt z.B. in einem Sichtfenster S eines Gehäuses G einen Farb- und/oder Transparenzwechsel. Dieser dient einer lokalen Anzeige der Funktionsfähigkeit/Funktionsunfähigkeit.With the embodiment described above, it is possible to provide a space-optimized separation device, which can also be realized inexpensively. The space-optimized separating device 1 shows e.g. in a viewing window S of a housing G a color and / or transparency change. This serves for a local display of functionality / malfunction.

Damit ist es nun möglich, bei unzulässiger Erwärmung mindestens eines der elektronischen Bauelemente, eine Abtrennung des jeweiligen elektronischen Bauelements durchführen, wobei der erforderliche Bauraum gering ist. Die Vorrichtung kann auch bei großen Temperaturanstiegen sicher abschalten. Die Vorrichtung ist zudem kostengünstig herstellbar. Zudem kann die Abtrennung eines elektronischen Bauelements oder mehrerer elektronischer Bauelemente signalisiert werden. elektronisches Bauelement EB1 elektronisches Bauelement EB2 Sichtfenster S nicht abgetrennt nicht abgetrennt OK abgetrennt nicht abgetrennt defekt nicht abgetrennt abgetrennt defekt abgetrennt abgetrennt defekt Thus, it is now possible to carry out an inadmissible heating of at least one of the electronic components, a separation of the respective electronic component, wherein the required space is small. The device can safely shut down even at high temperature rises. The device is also inexpensive to produce. In addition, the separation of an electronic component or a plurality of electronic components can be signaled. Electronic component EB 1 electronic component EB 2 Viewing window S not separated not separated OK detached not separated malfunction not separated detached malfunction detached detached malfunction

In einer vorteilhaften Ausgestaltung weist das mechanisch verschiebbare Anzeigemittel ANZ eine Einrichtung zur Fixierung F des mechanisch verschiebbaren Anzeigemittels ANZ in Ausgangsposition auf. D.h. in Figur 1 bewirkt die Einrichtung zur Fixierung F, dass das mechanische Anzeigemittel von dem am Träger P fixierten elektronischen Bauelement EB1 (und ebenso auch von dem am Träger P fixierten elektronischen Bauelement EB2) gehalten wird.In an advantageous embodiment, the mechanically displaceable display means ANZ has a device for fixing F of the mechanically displaceable display means ANZ in the starting position. Ie in FIG. 1 causes the means for fixing F, that the mechanical display means by the fixed to the carrier P electronic component EB 1 (and also by the fixed to the carrier P electronic component EB 2 ) is held.

D.h. das Anzeigemittel kann im Herstellungsprozess einfach nach der Montage des Trägers P mit den zu überwachenden elektronischen Bauelementen eingelegt werden. Hierdurch können die Herstellungskosten gering gehalten werden.That is, the display means can be easily inserted in the manufacturing process after the mounting of the carrier P with the electronic components to be monitored. As a result, the manufacturing costs can be kept low.

In einer weiteren vorteilhaften Ausgestaltung weist die Abtrennvorrichtung 1 für ein abgetrenntes zu überwachendes elektronisches Bauelement eine Einrichtung zur Fixierung F in einem abgetrennten Zustand auf.In a further advantageous embodiment, the separating device 1 for a separate to be monitored electronic component on a device for fixing F in a separated state.

Beispielsweise ist in Figur 2 die Einrichtung zur Fixierung F so gestaltet, dass das abgetrennte elektronische Bauelement EB1 im (geschlossenen) Gehäuse mittels der Einrichtung zur Fixierung F gehalten wird, sodass es keinen Kontakt zu seinen elektrischen Anschlüssen aufweist. In Figur 3 ist aufgezeigt, dass die Einrichtung zur Fixierung F so gestaltet sein kann, dass jedes abgetrennte elektronische Bauelement EB1 ,EB2 im (geschlossenen) Gehäuse mittels der Einrichtung zur Fixierung F gehalten wird, sodass es keinen Kontakt zu seinen jeweiligen elektrischen Anschlüssen aufweist. Dabei ist anzumerken, dass die Ausgestaltung wie in den Figuren dargestellt es auch erlaubt, dass nachdem z.B. das erste elektronische Bauelement EB1 abgetrennt wurde auch noch das zweite elektronische Bauelement EB2 abgetrennt wird und dieses dennoch sicher durch die Einrichtung zur Fixierung F gehalten wird (wie in Figur 3 dargestellt).For example, in FIG. 2 the device for fixing F designed so that the separated electronic component EB 1 is held in the (closed) housing by means of the fixing device F, so that it has no contact with its electrical connections. In FIG. 3 shows that the means for fixing F can be designed so that each separated electronic component EB 1 , EB 2 is held in the (closed) housing by means of the fixing device F, so that it has no contact with its respective electrical terminals. It should be noted that the embodiment as shown in the figures also allows that after, for example, the first electronic component EB 1 was separated and the second electronic component EB 2 is separated and this is still held securely by the device for fixing F ( as in FIG. 3 shown).

Durch die Einrichtung zur Fixierung F wird verhindert, dass gelöste abgetrennte elektronische Bauelemente an anderer Stelle Kurzschlüsse herstellen.By the means for fixing F prevents dissolved separated electronic components produced elsewhere shorts.

Alternativ oder zusätzlich kann auch ein "fangendes" Lötpad auf dem Träger P vorgesehen sein, sodass z.B. ein noch vorhandener flüssiger Lotrest an den Anschlüssen des ausgelösten elektronischen Bauelements dort erkaltet und so das abgetrennte elektronische Bauelement fixiert.Alternatively or additionally, a "catching" solder pad may also be provided on the carrier P, so that e.g. a still existing liquid Lotrest at the terminals of the triggered electronic component cooled there and so fixes the separated electronic component.

In einer weiteren vorteilhaften Ausgestaltung ist die Einrichtung zur Fixierung F und das mechanisch verschiebbare Anzeigemittel ANZ einstückig ausgeführt, wobei die Einrichtung zur Fixierung F Fixierung flexibel relativ zum mechanisch verschiebbaren Anzeigemittel ANZ ist. Hierdurch können - wie aus dem Vergleich der Figur 2 und Figur 3 ersichtlich ist - die Herstellungskosten gering gehalten werden.In a further advantageous embodiment, the device for fixing F and the mechanically displaceable display means ANZ is made in one piece, wherein the means for fixing F fixing is flexible relative to the mechanically displaceable display means ANZ. This can - as from the comparison of FIG. 2 and FIG. 3 it can be seen - the production costs are kept low.

Zum Zwecke der Fixierung im Anfangszustand bzw. Endzustand sind die Einrichtungen zur Fixierung F als Schrägen ausgestaltet, sodass ein "ausgelöstes" elektronisches Bauelement zusammen mit dem mechanisch verschiebbaren Anzeigemittel ANZ an einem nicht- "ausgelösten" elektronisches Bauelement vorbeigleiten kann - siehe Figur 2.For the purpose of fixing in the initial state or final state, the devices for fixing F are designed as bevels, so that a "triggered" electronic component along with the mechanically displaceable display means ANZ can slip past a non-"triggered" electronic component - see FIG. 2 ,

Weiterhin können in einer Ausgestaltung der Erfindung auch im Gehäuse G erste Führungseinrichtungen FG vorgesehen sein, um das mechanische Anzeigemittel zu führen. Beispielsweise können diese in einem Spritzgussverfahren kostengünstig angeformt sein.Furthermore, in one embodiment of the invention, first guide means FG may also be provided in the housing G in order to guide the mechanical display means. For example, these can be formed inexpensively in an injection molding process.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung können im Gehäuse auch zweite Führungseinrichtungen vorgesehen sein, um ein abzutrennendes elektronisches Bauelement zu führen.In a further advantageous embodiment of the invention, second guide means may also be provided in the housing in order to guide an electronic component to be cut off.

In einer vorteilhaften Ausgestaltung der Erfindung sind die Kraftspeicher D1 D2 Federn. Diese können nach Fixierung der elektronischen Bauelemente EB1 und EB2 kostengünstig eingebracht werden, sodass es z.B. keiner aufwändigen Befestigung der elektronischen Bauelemente EB1 und EB2 während des Fixierens auf dem Träger P bedarf.In an advantageous embodiment of the invention, the energy storage D 1 D 2 springs. These can be inexpensively introduced after fixation of the electronic components EB 1 and EB 2 , so that, for example, no complex attachment of the electronic components EB 1 and EB 2 during fixation on the support P is required.

Ohne Weiteres kann die bauraumoptimierte Abtrennvorrichtung Einrichtungen zur Montage auf eine Tragschiene aufweisen.Without further ado, the space-optimized separating device can have devices for mounting on a mounting rail.

Die Erfindung ist für jegliche Art von zu überwachenden elektronischen Bauelementen geeignet. Insbesondere sind die elektronischen Bauelemente ausgewählt aus einer Gruppe aufweisend Halbleiter, insbesondere Varistoren, TVS-Dioden oder Gasableiter.The invention is suitable for any type of electronic components to be monitored. In particular, the electronic components are selected from a group comprising semiconductors, in particular varistors, TVS diodes or gas arresters.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung weist die thermisch erweichbare Fixierung ein Lot oder einen Kleber auf. D.h. das elektronische Bauelement kann mittels eines thermisch erweichbaren Lotes, das zudem eine elektrische Verbindung bereitstellt, auf dem Träger P fixiert sein. Alternativ oder zusätzlich kann auch ein thermisch erweichbarer Kleber das elektronische Bauelement auf dem Träger P fixieren.In a further advantageous embodiment of the invention, the thermally softenable fixation on a solder or an adhesive. That the electronic component can be fixed on the carrier P by means of a thermally softenable solder, which also provides an electrical connection. Alternatively or additionally, a thermally softenable adhesive can fix the electronic component on the carrier P.

Bevorzugt sind das Gehäuse G und/oder das mechanisch verschiebbare Anzeigemittel ANZ aus einem Kunststoffmaterial gefertigt.Preferably, the housing G and / or the mechanically displaceable display means ANZ are made of a plastic material.

Hierdurch können Fehler zusätzlich an einen entfernten Nutzer signalisiert werden.Without restricting the general public, it can also be provided that each of the separating devices 1 has its own telecommunication device. As a result, errors can be additionally signaled to a remote user.

Alternativ oder zusätzlich kann auch eine passive optische Summenfernmeldung für mehrere nebeneinanderliegende erfindungsgemäße Abtrennvorrichtungen 1 bereitgestellt werden. Dies wird aus Figur 1 ersichtlich, in der in den Gehäusen G ein im Ausgangzustand freie Fernmeldeöffnung FM vorgesehen ist, die im Fehlerfall (Figur 2 und 3) überdeckt ist. Werden nun die nebeneinanderliegenden erfindungsgemäßen Abtrennvorrichtungen 1 (auf einer Schiene) so nebeneinander angeordnet, dass ein Lichtstrahl alle Fernmeldeöffnungen passieren kann, so kann die Rückstrahlung bzw. die fehlende Durchstrahlung mittels eines lichtempfindlichen Elements als Summenalarm ausgewertet werden und somit eine kostengünstige Summenalarmierung zur Verfügung stellen. D.h. mehrere bauraumoptimierte Abtrennvorrichtungen 1 stellen in einer nebeneinanderliegenden Anordnung eine Summenfehlermeldung in normaler Richtung zum Träger P zur Verfügung.
