Aus der DE 34 30 922 A1 ist ein Überspannungsableiter- und Stromsicherungs-Magazin bekannt, bei dem für jeden Leitungsweg mit Zuleitung und Ableitung eine Stromsicherung und/oder ein Überspannungs-Doppelableiter im Überspannungsschutzmagazin mittels Kontaktfedern in eine Halterung einklemmbar sind, wobei an der Unterseite des steckbar ausgebildeten Überspannungsschutzmagazins je Leitungsweg an der Vorder- und Rückseite je eine Kontaktbahn als Trennelement vorgesehen ist, die mit je einem Pol der Stromsicherung verbunden ist, wobei die Pole der Stromsicherungen mit je einem Pol des Überspannungs-Doppelableiters verbunden sind und die Mittelkontakte der Überspannungs-Doppelableiter an einer gemeinsamen Erdschiene liegen, die mit zwei Erdabgriffklemmen verbunden ist. Nachteilig an dem bekannten Überspannungsschutzmagazin ist dessen großer Bauraum, insbesondere da sowohl die Überspannungs-Doppelableiter als auch die Stromsicherungen jeweils in zwei Reihen angeordnet sind.From the DE 34 30 922 A1 a surge arrester and current fuse magazine is known in which a current fuse and / or a surge arrester in the overvoltage protection magazine can be clamped by means of contact springs in a holder for each conduction with lead and derivative, wherein at the bottom of the pluggable surge protection magazine per line path at the Front and back ever a contact path is provided as a separator, which is connected to one pole of the current fuse, the poles of the current fuses are each connected to a pole of the surge double arrester and the center contacts of the surge double arrester lie on a common ground rail, which is connected to two Erdabgriffklemmen. A disadvantage of the known overvoltage protection magazine is its large installation space, in particular because both the overvoltage double arrester and the current fuses are each arranged in two rows.

Aus der DE 198 18 477 A1 ist ein Überspannungsschutzmagazin für eine Einrichtung der Telekommunikationstechnik bekannt, mit einem Gehäuse, mehreren Kontakten, die sich mit einem Abschnitt von der Gehäuserückseite erstrecken und im angebrachten Zustand Kontakte der Einrichtung der Telekommunikationstechnik abgreifen, und zumindest einem Erdkontakt, wobei in das Überspannungsschutzmagazin mehrere Überspannungsableiter einsetzbar sind, die Beinchen aufweisen, die im eingesetzten Zustand mit den Kontakten unmittelbar elektrisch leitend verbunden sind, wobei die Kontakte jeweils einen Kontaktschlitz aufweisen, der durch zwei weitgehend in einer Ebene liegende Kontaktschenkel definiert ist, die Überspannungsableiter von der Vorderseite des Gehäuses in Richtung ihrer Beinchen derart einsetzbar sind, dass sich im eingesetzten Zustand das jeweilige Beinchen in einer Richtung weitgehend parallel zu dem Kontaktschlitz in diesen erstreckt und sich die Überspannungsableiter alternierend auf zumindest zwei unterschiedlichen Niveaus hinsichtlich der Tiefenerstreckung des Überspannungsschutzmagazins befinden, so dass diese von der Oberseite aus betrachtet zueinander versetzt angeordnet sind. Hierdurch kann das Überspannungsschutzmagazin auf eine Leiterplatte verzichten. Nachteilig an dem bekannten Überspannungsschutzmagazin ist dessen immer noch verhältnismäßig großer Bauraum sowie die doch recht aufwendige Fertigung.From the DE 198 18 477 A1 is an overvoltage protection magazine for a device of telecommunications technology known, comprising a housing, a plurality of contacts which extend with a portion of the back of the housing and tapped in the attached state contacts the device of the telecommunications technology, and at least one ground contact, wherein in the overvoltage protection magazine more surge arresters can be used , Which have legs that are directly electrically connected to the contacts in the inserted state, wherein the contacts each have a contact slot which is defined by two largely lying in a plane contact legs, the surge from the front of the housing in the direction of their legs so can be used that in the inserted state, the respective legs extend in a direction substantially parallel to the contact slot in these and the surge arresters are alternately on at least two different levels with respect to the depth extent of the overvoltage protection magazine, so that they are arranged offset from one another viewed from the top. As a result, the overvoltage protection magazine can do without a printed circuit board. A disadvantage of the known overvoltage protection magazine whose still relatively large space and the quite expensive production.

Aus der EP 0 460 223 B1 ist ein Überspannungsschutzmagazin für eine Einrichtung der Telekommunikationstechnik bekannt, umfassend ein Gehäuse, eine Leiterplatte, mehrere Überspannungsableiter und mindestens einen Erdkontakt, wobei die Überspannungsableiter auf der Leiterplatte angeordnet sind und über Leiterbahnen zu auf der Leiterplatte angeordneten Kontaktpads geführt sind, die im gesteckten Zustand in elektrischen Kontakt mit Kontakten der Einrichtung für die Telekommunikation kommen, wobei die Überspannungsableiter in einer Reihe angeordnet sind. Dabei sind die Kontaktpads mit separaten Kontakten verbunden, die dann in eine weitere Leiterplatte der Einrichtung für die Telekommunikation gesteckt werden.From the EP 0 460 223 B1 an overvoltage protection magazine for a device of telecommunications technology is known, comprising a housing, a printed circuit board, a plurality of surge arresters and at least one ground contact, wherein the surge arresters are arranged on the circuit board and are guided via printed conductors to arranged on the circuit board contact pads, which in the inserted state in electrical Contact with contacts of the telecommunications device come, with the surge arresters are arranged in a row. The contact pads are connected to separate contacts, which are then plugged into another circuit board of the device for telecommunications.

Der Erfindung liegt daher das technische Problem zugrunde, ein Überspannungsschutzmagazin zu schaffen, das mit geringem Bauraum einfach zu fertigen ist.The invention is therefore based on the technical problem of creating a surge protection magazine that is easy to manufacture with little space.

Die Lösung des technischen Problems ergibt sich durch den Gegenstand mit den Merkmalen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the technical problem results from the subject matter with the features of claim 1. Further advantageous embodiments of the invention will become apparent from the dependent claims.

Hierzu werden die Überspannungsableiter in einer Reihe auf einer Leiterplatte angeordnet. Dies ermöglicht einen einfachen Aufbau mit einfacher Führung der Leiterbahnen, wobei die Leiterplatte relativ schmal gehalten werden kann. Weiter ist die Leiterplatte im unteren Bereich durch Freischnitte strukturiert, so dass sich entsprechend der Anzahl der Überspannungsableiter Einsteckbereiche ausbilden, wobei zu jedem Einsteckbereich die beiden äußeren Elektroden des ihm zugeordneten Überspannungsableiters durch Leiterbahnen geführt sind, wobei am Randbereich der Leiterplatte für jede äußere Elektrode ein Kontaktpad angeordnet ist, das auf der Vorder- und Rückseite der Leiterplatte angeordnet ist.For this purpose, the surge arresters are arranged in a row on a printed circuit board. This allows a simple structure with simple guidance of the conductor tracks, wherein the circuit board can be kept relatively narrow. Next, the PCB is structured in the lower area by free cuts, so that form insertion regions according to the number of surge arresters, wherein the two outer electrodes of the associated surge arrester are guided by conductor tracks for each insertion, wherein at the edge region of the circuit board for each outer electrode, a contact pad is arranged, which is arranged on the front and back of the circuit board ,

Vorzugsweise sind die Überspannungsableiter als SMD-Überspannungsableiter ausgebildet, wodurch eine einfache Bestückung der Leiterplatte möglich ist. Ein weiterer Vorteil der SMD-Bauelemente ist das einfachere Recycling. Durch Erwärmen der Leiterplatte fallen die SMD-Bauelemente ab, so dass Leiterplatte und Überspannungsableiter einfach zu trennen sind. Bei Überspannungsableitern mit Kontaktbeinchen hingegen kommt es häufig zu Verkantungen, so dass die Bauelemente manuell von der Leiterplatte getrennt werden müssen.Preferably, the surge arresters are designed as SMD surge arresters, whereby a simple assembly of the circuit board is possible. Another advantage of the SMD components is the easier recycling. By heating the printed circuit board, the SMD components fall off, so that the printed circuit board and surge arresters are easy to disconnect. In the case of surge arresters with contact legs, on the other hand, tilting often occurs, with the result that the components must be separated manually from the printed circuit board.

In einer weiteren bevorzugten Ausführungsform ist das Gehäuse einstückig ausgebildet, was die Herstellungskosten reduziert. Dies ist insbesondere deshalb möglich, da der Kontakt zu den elektrischen Kontakten der Einrichtung über die Kontaktpads auf der Leiterplatte erfolgt. Da die Leiterplatte relativ starr ist, kann die strukturierte Leiterplatte einfach durch vorgesehene Öffnungen im Gehäuse durchgesteckt werden. Bei Ausführungsformen aus dem Stand der Technik, wo separate Kontakte an die Leiterplatte ausgelötet oder direkt an die Überspannungsableiter befestigt werden, ist das Spiel zwischen den Kontakten relativ groß, so dass einstückige Gehäuse unpraktisch sind.In a further preferred embodiment, the housing is formed in one piece, which reduces the manufacturing cost. This is particularly possible because of Contact with the electrical contacts of the device via the contact pads on the circuit board takes place. Since the circuit board is relatively rigid, the structured circuit board can be easily inserted through openings provided in the housing. In prior art embodiments where separate contacts are soldered to the printed circuit board or attached directly to the surge arresters, the clearance between the contacts is relatively large, so that one-piece housings are impractical.

In einer weiteren bevorzugten Ausführungsform ist das Gehäuse an der Oberseite offen und durch einen Isolator-Streifen abgedeckt. Hierdurch wird mit einfachen Mitteln ein Berührungsschutz für den Anwender geschaffen. Vorzugsweise ist der Isolator-Streifen als Plastikstreifen ausgebildet, der bedarfsweise gleichzeitig zur Beschriftung verwendet werden kann.In a further preferred embodiment, the housing is open at the top and covered by an insulator strip. As a result, contact protection for the user is created by simple means. Preferably, the insulator strip is formed as a plastic strip, which can be used if necessary, at the same time for labeling.

In einer weiteren bevorzugten Ausführungsform ist das Gehäuse an den Innenseiten mit Auflagen für den Isolator-Streifen ausgebildet, damit dieser ausreichend am Gehäuse abgestützt ist.In a further preferred embodiment, the housing is formed on the insides with pads for the insulator strip so that it is sufficiently supported on the housing.

In einer weiteren bevorzugten Ausführungsform ist das Gehäuse mit halbzylinderförmigen Einbuchtungen ausgebildet, wobei die halbzylinderförmigen Einbuchtungen im Bereich der Oberseite des Gehäuses geschlitzt ausgebildet sind und der Isolier-Streifen zwischen den Schlitzen geführt ist. Hierdurch wird neben einer ausreichenden Auflagefläche der Isolier-Streifen fixiert und das Gehäuse mechanisch stabilisiert.In a further preferred embodiment, the housing is formed with semi-cylindrical indentations, wherein the semi-cylindrical indentations are formed slotted in the region of the top of the housing and the insulating strip is guided between the slots. As a result, in addition to a sufficient contact surface of the insulating strips is fixed and the housing mechanically stabilized.

In einer weiteren bevorzugten Ausführungsform sind die Ränder des Gehäuses an der Oberseite an den Seiten abgesetzt, so dass der Isolier-Streifen mit der Oberseite des Gehäuses abschließt. Hierdurch wird erreicht, dass die Kanten des Gehäuses beim Eindrücken des Überspannungsmagazins nicht in die Finger des Monteurs drücken und dieser über die volle Breite drücken kann.In a further preferred embodiment, the edges of the housing are offset at the top at the sides, so that the insulating strip terminates with the top of the housing. This ensures that the edges of the housing when pressing the overvoltage magazine does not press into the fingers of the fitter and this can press over the full width.

In einer weiteren bevorzugten Ausführungsform ist das Gehäuse an der Stirnseite mit mindestens einem Schlitz ausgebildet, über den mittels eines Werkzeuges der Isolier-Streifen herausgehebelt werden kann.In a further preferred embodiment, the housing is formed on the end face with at least one slot, can be levered out by means of a tool of the insulating strip.

In einer weiteren bevorzugten Ausführungsform ist der Erdkontakt als Gabelkontakt ausgebildet und über den Gabelkontakt mit der Leiterplatte verbunden, wobei der Gabelkontakt vorzugsweise als Doppel-Gabelkontakt ausgebildet ist. Hierdurch ist ein lötfreies Verbinden des Gabelkontaktes mit der Leiterplatte möglich.In a further preferred embodiment, the ground contact is designed as a fork contact and connected via the fork contact with the circuit board, wherein the fork contact is preferably designed as a double fork contact. As a result, a solder-free connection of the fork contact with the circuit board is possible.

In einer weiteren bevorzugten Ausführungsform sind die Überspannungsableiter als Fail-Safe ausgebildet.In a further preferred embodiment, the surge arresters are designed as fail-safe.

In einer weiteren bevorzugten Ausführungsform sind die Kontaktpads der Leiterplatte aus Silber, da Silber eine ausreichende mechanische Festigkeit aufweist.In a further preferred embodiment, the contact pads of the printed circuit board are made of silver, since silver has sufficient mechanical strength.

In einer weiteren bevorzugten Ausführungsform ist das Gehäuse an der Unterseite im Bereich der Gabelkontakte mit Freischnitten ausgebildet, so dass das Überspannungsschutzmagazin im aufgesteckten Zustand auf einer Verteilerleiste mittels eines Werkzeuges leicht herausgehebelt werden kann.In a further preferred embodiment, the housing is formed on the underside in the region of the fork contacts with cutouts, so that the overvoltage protection magazine can be easily levered out in the mounted state on a distribution strip by means of a tool.

In der Fig. 1 ist das Überspannungsschutzmagazin 1 in einer Explosionsdarstellung vor dem Zusammenbau dargestellt. Das Überspannungsschutzmagazin 1 umfasst ein einteiliges Gehäuse 2, eine Leiterplatte 3 mit Überspannungsableitern 4, einen Isolier-Streifen 5 und zwei Erdkontakte 6. Die Überspannungsableiter 4 sind als SMD-Bauelemente ausgebildet und in einer Reihe auf der Leiterplatte 3 angeordnet. Die Mittelkontakte 7 aller Überspannungsableiter 6 sind über eine gemeinsame, nicht dargestellte Leiterbahn mit zwei Kontaktpads 8 verbunden. Die Kontaktpads 8 sind dabei sowohl auf der Vorder- als auch der Rückseite der Leiterplatte 3 angeordnet. Im unteren Bereich ist die Leiterplatte 3 durch Freischnitte strukturiert, so dass sich entsprechend der Anzahl der Überspannungsableiter 4 Einsteckbereiche 9 ausbilden. Zu jedem Einsteckbereich 9 werden die beiden äußeren Elektroden des ihm zugeordneten Überspannungsableiters 4 durch Leiterbahnen geführt, wobei am Randbereich der Leiterplatte 3 für jede Elektrode ein Kontaktpad 11 angeordnet ist. Die Kontaktpads 11 sind ebenfalls auf der Vorder- und Rückseite der Leiterplatte 3 angeordnet. Das einstückige Gehäuse 2 ist im Wesentlichen quaderförmig ausgebildet. An den seitlichen Bereichen ist das Gehäuse 2 mit Verlängerungen 12 ausgebildet. Des weiteren ist das Gehäuse 2 mit halbzylinderförmigen Einbuchtungen 13 ausgebildet. Im Bereich des oberen Randes 14 sind Schlitze 15 in das Gehäuse 2 eingearbeitet, so dass der nach innen ragende Halbzylinder getrennt wird. Der obere Rand 14 ist zu den beiden Stirnseiten 16 hin durch eine Schräge 17 abgesetzt, also flacher ausgebildet. Des weiteren weist das Gehäuse 2 an den Stirnseiten 16 Schlitze 18 auf. Der Erdkontakt 6 weist im oberen Bereich einen Doppel-Gabelkontakt 19 und im unteren Bereich einen Einfach-Gabelkontakt 20 auf. Das Gehäuse 2 ist darüber hinaus im unteren Bereich mit Öffnungen für die Einsteckbereiche 9 ausgebildet. Zur Stabilisierung dienen geschlossene Stege 21, die jeweils zwischen zwei Einsteckbereichen 9 liegen und Stege 22, die geschlitzt sind und zwischen den beiden Kontaktpads 11 aufliegen. Zum Zusammenbau werden zunächst die beiden Erdkontakte 6 von oben in das Gehäuse 2 eingesteckt, wobei die Erdkontakte im gesteckten Zustand durch die Verlängerungen 12 geführt werden. Im komplett gesteckten Zustand ragt dann der Einfach-Gabelkontakt 20 aus der Verlängerung 12 heraus, was im linken Teil der Fig. 1 dargestellt ist. Anschließend wird die Leiterplatte 3 eingeschoben, wobei die Einsteckbereiche 9 durch die unteren Öffnungen im Gehäuse 2 treten. Gleichzeitig kontaktieren die Doppel-Gabelkontakte 19 die Kontaktpads 8. Im letzten Schritt wird dann der Isolier-Streifen 5 in das Gehäuse 2 gedrückt, so dass die Ränder des Isolier-Streifens 5 in die Schlitze 15 gelangen. Dadurch liegt der Isolier-Streifen 5 auf dem unteren Teil des Halbzylinders auf und wird vom oberen Teil des Halbzylinders gehalten. An den seitlichen Bereichen an den Schrägen 17 liegt dabei der Isolier-Streifen 5 in einer Ebene mit dem Rand des Gehäuses.In Fig. 1, the overvoltage protection magazine 1 is shown in an exploded view prior to assembly. The overvoltage protection magazine 1 comprises a one-piece housing 2, a printed circuit board 3 with surge arresters 4, an insulating strip 5 and two earth contacts 6. The surge arresters 4 are formed as SMD components and arranged in a row on the printed circuit board 3. The center contacts 7 of all surge 6 are connected via a common, not shown trace with two contact pads 8. The contact pads 8 are arranged both on the front and the back of the circuit board 3. In the lower region, the printed circuit board 3 is structured by free cuts, so that 4 plug-in regions 9 form according to the number of surge arresters. For each insertion region 9, the two outer electrodes of its associated surge arrester 4 are guided by conductor tracks, wherein at the edge region of the circuit board 3, a contact pad 11 is arranged for each electrode. The contact pads 11 are also arranged on the front and back of the circuit board 3. The one-piece housing 2 is formed substantially cuboid. At the lateral areas, the housing 2 is formed with extensions 12. Furthermore, the housing 2 is formed with semi-cylindrical indentations 13. In the region of the upper edge 14 slots 15 are incorporated into the housing 2, so that the inwardly projecting half-cylinder is separated. The upper edge 14 is offset to the two end faces 16 through a slope 17, that is flatter. Furthermore, the housing 2 at the end faces 16 slots 18. The earth contact 6 has a double fork contact 19 in the upper region and a single fork contact 20 in the lower region. The housing 2 is also formed in the lower region with openings for the Einsteckbereiche 9. To stabilize serve closed webs 21, each of which lies between two Einsteckbereichen 9 and webs 22 which are slotted and rest between the two contact pads 11. For assembly, the two ground contacts 6 are first inserted from above into the housing 2, wherein the ground contacts are passed through the extensions 12 in the inserted state. In the fully mated condition, the single fork contact 20 projects out of the extension 12, which is shown in the left-hand part of FIG. Subsequently, the circuit board 3 is inserted, wherein the Insertion regions 9 pass through the lower openings in the housing 2. At the same time the double fork contacts 19 contact the contact pads 8. In the last step, the insulating strip 5 is then pressed into the housing 2, so that the edges of the insulating strip 5 pass into the slots 15. As a result, the insulating strip 5 rests on the lower part of the half cylinder and is held by the upper part of the half cylinder. At the lateral areas on the slopes 17 of the insulating strip 5 is in a plane with the edge of the housing.

In der Fig. 2 und 3 ist das Überspannungsschutzmagazin 1 im zusammengesteckten Zustand dargestellt, wobei der Isolier-Streifen 5 in Fig. 2 unterbrochen dargestellt ist, wobei die gleichen Bezugszeichen wie Fig. 1 verwendet wurden.2 and 3, the overvoltage protection magazine 1 is shown in the assembled state, wherein the insulating strip 5 is shown in broken in Fig. 2, wherein the same reference numerals as in Fig. 1 were used.

In der Fig. 4 ist das Überspannungsschutzmagazin 1 aufgesteckt auf eine Schaltleiste 23 dargestellt. Die Schaltleiste 23 weist zwei Kontaktreihen 24, 25 auf, die um 90° zueinander versetzt angeordnet sind. Dabei ist die obere Kontaktreihe 24 mit aufgestecktem Überspannungsschutzmagazin 1 nicht mehr zugänglich, wohingegen die zweite Kontaktreihe 25 frei zugänglich ist. Aufgrund von Freischnitten des Gehäuses 2 im Bereich der Verlängerungen 12 kann das Überspannungsschutzmagazin 1 mittels der Klinge 26 eines Werkzeuges 27 herausgehebelt werden. Beim Aufstecken des Überspannungsschutzmagazins 1 kontaktieren die Einsteckbereiche 9 aus den Fig. 1-3 nicht sichtbare Mittelabgriffe der Schaltleiste 23, wodurch jeweils ein Kontakt der ersten und zweiten Kontaktreihe 24, 25 mit einer Elektrode eines Überspannungsableiters 4 (siehe Fig. 1) verbunden wird. Gleichzeitig dringen die beiden Erdkontakte 6 jeweils in einen quaderförmigen Bereich 28, wo diese jeweils einen nicht sichtbaren Erdabgriff kontaktieren. Mittels der klammerartigen Aufnahmeelemente 29 kann dann die Schaltleiste 23 auf die nicht dargestellten Profilstangen aufgerastet werden, wobei dann der Erdabgriff die Profilstange kontaktiert. Hierdurch entsteht eine leitende Erdverbindung von den Mittelabgriffen der Überspannungsableiter zu den Profilstangen.In FIG. 4, the overvoltage protection magazine 1 is plugged onto a switching strip 23. The switching strip 23 has two rows of contacts 24, 25, which are arranged offset by 90 ° to each other. In this case, the upper row of contacts 24 is no longer accessible with plugged over voltage protection magazine 1, whereas the second row of contacts 25 is freely accessible. Due to cutouts of the housing 2 in the region of the extensions 12, the overvoltage protection magazine 1 can be levered out by means of the blade 26 of a tool 27. When attaching the overvoltage protection magazine 1 contact the Einsteckbereiche 9 of FIGS. 1-3 not visible Mittelabgriffe the switching strip 23, whereby in each case a contact of the first and second contact row 24, 25 with an electrode of a surge arrester 4 (see FIG. 1) is connected. At the same time, the two ground contacts 6 each penetrate into a parallelepiped-shaped region 28, where they each contact an invisible earth tap. By means of the clip-like receiving elements 29, the switching strip 23 can then be snapped onto the profile bars, not shown, in which case the ground tap contacted the profile bar. This creates a conductive ground connection from the center taps of the surge arrester to the profile bars.
