Abstract

A safety subassembly (12, 31) can be plugged on the rear plug contacts (15) of a contact component (4) of the distribution board. The safety subassembly contains surge arresters (20, 29) connected to an earth conductor (for example 26, 31) which may be contacted with the operational earth of a carrier assembly (2) for the contact components (4). Contact is ensured by earth contacting springs (27) which extend along the narrow front sides of the safety subassembly (12, 13) in the plugging direction. The safety subassembly may thus have a compact design and be earthed at a low cost.

Schutzbaugruppe für einen Verteiler in einer Telekommunika- tionsanlägeProtective assembly for a distributor in a telecommunications system
Die Erfindung bezieht sich auf eine Schutzbaugruppe zum An¬ stecken an ein Kontaktbauteil eines Verteilers in einer Tele- kommunikationsanlage.The invention relates to a protective module for connection to a contact component of a distributor in a telecommunications system.
Eine derartige Schutzbaugruppe ist z.B. durch dieSuch a protective assembly is e.g. through the
DE 36 25 476 AI bekannt geworden. Danach ist ein Kontaktbau¬ teil mit einer Vielzahl von Kontaktteilen zum Anschluß von ankommenden und abgehenden Leitungen versehen. Die Kontakt- teile sind mit rückseitigen Steckkontakten verbunden, die mit einer entsprechenden Vielzahl von Steckkontaktstellen der Schutzbaugruppe kontaktierbar sind. Die Schutzbaugruppe ist von der der Bedienseite abgewandten Rückseite des Kontaktbau¬ teils her an die Steckkontakte anschaltbar. Sie weist eine gedruckte Leiterplatte auf, die mit Stromsicherungen und Überspannungsableitern bestückt ist. Eine für alle Überspan¬ nungsabieiter gemeinsame Erdleiterbahn erstreckt sich bis in den Stirnseitenbereich der Schutzbaugruppe und bildet dort Kontaktzonen, die mit Federkontakten eines ErdkontaktStrei¬ fens kontaktierbar sind, der an einem Trägerteil für die Kon- taktbauteile befestigt ist.DE 36 25 476 AI become known. Thereafter, a contact component is provided with a multiplicity of contact parts for connecting incoming and outgoing lines. The contact parts are connected to rear-side plug contacts which can be contacted with a corresponding number of plug-in contact points on the protective module. The protective assembly can be connected to the plug contacts from the rear side of the contact component facing away from the operating side. It has a printed circuit board that is equipped with current fuses and surge arresters. An earth conductor track common to all surge arresters extends into the end face area of the protective assembly and forms contact zones there which can be contacted with spring contacts of an earth contact strip which is fastened to a carrier part for the contact components.
Der sich über mehrere Kontaktbauteile erstreckende Erdkon¬ taktstreifen weist freigestanzte Federarme auf, zwischen die die entsprechenden Kontaktzonen der Leiterplatte einschiebbar sind. Es ist üblich, die Schutzbaugruppe zunächst von derThe earth contact strip, which extends over several contact components, has punched-out spring arms, between which the corresponding contact zones of the printed circuit board can be inserted. It is common to first remove the protective assembly from the
Seite her durch eine Öffnung im Trägerteil einzuschieben und danach auf das Kontaktbauteil aufzustecken. Die Federarme ra¬ gen in den Bereich der Öffnung hinein. Die Querschnittskontur der Schutzbaugruppe muß daher so ausgebildet sein, daß beim seitlichen Einschieben der Schutzbaugruppe keine Kollision mit den Federarmen möglich ist. Der Erfindung liegt die Aufgabe zugrunde, eine einfache, raumsparende und sichere Kontaktierung der Schutzbaugruppe mit dem Trägerteil zu ermöglichen.Push it in through an opening in the carrier part and then plug it onto the contact component. The spring arms protrude into the area of the opening. The cross-sectional contour of the protective assembly must therefore be designed so that when the protective assembly is inserted laterally, no collision with the spring arms is possible. The invention has for its object to enable a simple, space-saving and safe contacting of the protective assembly with the carrier part.
Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 ge¬ löst.This object is achieved by the invention according to claim 1.
Da die Kontaktfeder nun an der Schutzbaugruppe befestigt ist, folgt sie deren Bewegungen beim seitlichen Einschieben, wie auch beim Einstecken in das Kontaktbauteil. Die Querschnitts¬ kontur der Schutzbaugruppe ist nun von der Form der Erdkon¬ taktfeder nicht mehr betroffen. Die Erdkontaktfeder benötigt lediglich einen geringen Raum für die seitliche Auslenkung beim Aufstecken der Schutzbaugruppe. Sie kann im Zuge der Be- stückung der Schutzbaugruppe angebracht und mit dem Erdleiter kontaktiert werden. Das Trägerteil für die Kontaktbauteile kann z.B. aus einem verchromten Stahlblech bestehen, mit dem die Erdkontaktfeder unmittelbar kontaktierbar ist.Since the contact spring is now attached to the protective assembly, it follows its movements when it is inserted laterally, as well as when it is inserted into the contact component. The cross-sectional contour of the protective assembly is no longer affected by the shape of the earth contact spring. The earth contact spring only requires a small space for the lateral deflection when the protective assembly is attached. It can be attached as part of the assembly of the protective module and contacted with the earth conductor. The carrier part for the contact components can e.g. consist of a chrome-plated sheet steel with which the earth contact spring can be contacted directly.
Durch eine Weiterbildung der Erfindung nach Anspruch 2 wird die Erdkontaktfeder in ähnlicher Weise kontaktiert, wie die Steckkontaktstellen der Schutzbaugruppe.Through a development of the invention according to claim 2, the earth contact spring is contacted in a manner similar to the plug contact points of the protective assembly.
Durch die Weiterbildung nach Anspruch 3 bestehen das Erdungs- blech und die Erdkontaktfeder aus einem Stück, so daß für die Ausbildung der Erdkontaktfeder nur sehr geringe Mehrkosten anfallen.Due to the development according to claim 3, the earthing plate and the earth contact spring consist of one piece, so that only very low additional costs are incurred for the formation of the earth contact spring.
Bei der Weiterbildung nach Anspruch 4 können die Anschlußele- mente der Erdkontaktfeder z.B. aus Einpreßstifte ausgebildet werden, die in durchkontaktierte Lötaugen der Leiterplatte eingedrückt werden. Es ist aber auch möglich, die Anschluße¬ lemente als Lötstifte auszubilden, die in die Lötaugen einge¬ setzt werden und die zusammen mit den Schutzelementen an der Leiterplatte angelötet werden, so daß dafür kein gesonderter Arbeitsgang nötig ist. Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zei¬ gen:In the development according to claim 4, the connection elements of the earth contact spring can be formed, for example, from press-in pins which are pressed into plated-through soldering eyes on the printed circuit board. However, it is also possible to design the connecting elements as solder pins which are inserted into the soldering eyes and which are soldered together with the protective elements to the circuit board, so that no separate operation is necessary for this. The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing. It shows:

Figur 1 zeigt einen Verteilerblock 1 mit einem Trägerteil 2, in dem scheibenartige Drahtführungen 3 und Kontaktbauteile 4 sandwichartig übereinander gestapelt sind. Die Drahtführungen 3 weisen bogenförmig gekrümmte Drahtführungskanäle 5 auf, in denen ankommende und abgehende Leitungen (17, Fig. 2) von Seitenwänden 6 zu einer Bedienseite 7 des Verteilerblockes geführt werden können. Die Kontaktbauteile 4 sind an dieser Seite mit Schneidklemmen 8 versehen, in deren Klemmschlitze die ankommenden und abgehenden Leitungen mittels eineε An¬ schlußwerkzeuges 9 kontaktgebend eingedrückt werden können. Die Schneidklemmen 8 sind mit Kontaktteilen verbunden, die im Inneren der Kontaktbauteile Trennkontakte bilden, die mittels von der Frontseite her einsteckbarer Trennstecker 10 unter¬ brochen werden können.FIG. 1 shows a distributor block 1 with a carrier part 2, in which disk-like wire guides 3 and contact components 4 are stacked one above the other in a sandwich-like manner. The wire guides 3 have curved wire guide channels 5, in which incoming and outgoing lines (17, FIG. 2) can be guided from side walls 6 to an operating side 7 of the distributor block. The contact components 4 are provided on this side with insulation displacement terminals 8, in the clamping slots of which the incoming and outgoing lines can be pressed in contacting manner by means of a connecting tool 9. The insulation displacement terminals 8 are connected to contact parts which form isolating contacts in the interior of the contact components, which can be interrupted by means of isolating plugs 10 which can be inserted from the front.
Die Kontaktbauteile 4 weisen auf ihrer der Bedienseite 7 ge¬ genüberliegenden Rückseite 11 Steckkontakte für eine seitlich in den Verteilerblock 1 einschiebbare Schutzbaugruppe 12 auf. Diese ist entlang ihrer dem Kontaktbauteil 4 zugewandten Frontseite 13 mit Steckkontaktstellen 14 versehen, die gemäß der angegebenen Pfeilrichtung zwischen die Steckkontakte der Kontaktbauteile 4 eingesteckt werden können.The contact components 4 have on their rear side, opposite the operating side 7, 11 plug contacts for a protective module 12 which can be inserted laterally into the distributor block 1. This is provided along its front side 13 facing the contact component 4 with plug contact points 14, which according to the indicated arrow direction between the plug contacts of the contact components 4 can be inserted.
Nach den Figuren 2, 3 und 4 sind die Steckkontaktstellen der Schutzbaugruppe 12 gemäß der angegebenen Pfeilrichtung zwi¬ schen Steckkontakte 15 von Kontaktteilen 16 des Kontaktbau¬ teils 4 einsteckbar. Die Kontaktbauteile 16 sind auf der der Schutzbaugruppe 12 gegenüberliegenden Bedienseite 7 des Kon¬ taktbauteils 4 mit den Schneidklemmen 8 verbunden, an denen die ankommenden und abgehenden Leitungen 17 angeschlossen sind.According to FIGS. 2, 3 and 4, the plug contact points of the protective assembly 12 can be plugged in between the plug contacts 15 of contact parts 16 of the contact component 4 according to the direction of the arrow. The contact components 16 are connected on the operating side 7 of the contact component 4 opposite the protective assembly 12 to the insulation displacement terminals 8 to which the incoming and outgoing lines 17 are connected.
Die Schutzbaugruppe 12 besteht aus einer Leiterplatte, einem rahmenartigen Gehäuseteil 19, Überspannungsableitern 20 und Stromsicherungen 21. Lötanschlüsse 22 der Uberspannungsablei- ter 20 bzw. Stromsicherungen 21 sind über Leiterbahnen 23 mit den Steckkontaktstellen 14 der Leiterplatte 18 verbunden. Das Gehäuseteil 19 ist mittels Klemmzapfen 24 in entsprechenden Klemmlöchern der Leiterplatte 18 fixiert. Das Gehäuseteil 19 ist so ausgebildet, daß es auf die Leiterplatte 18 nach dem Anlöten der Schutzelemente (20,21) aufgesetzt werden kann. Dies wird durch einen zur Leiterplatte hin offenen Durchbruch 25 ermöglicht, der die Schutzelemente umschließt. Eε ist aber auch möglich, für jedes einzelne Schutzelement oder für ein- zelne Gruppen der Schutzelemente jeweils einen Durchbruch vorzusehen.The protective assembly 12 consists of a printed circuit board, a frame-like housing part 19, surge arresters 20 and current fuses 21. Solder connections 22 of the surge arrester 20 or current fuses 21 are connected via conductor tracks 23 to the plug contact points 14 of the printed circuit board 18. The housing part 19 is fixed by means of clamping pins 24 in corresponding clamping holes in the printed circuit board 18. The housing part 19 is designed such that it can be placed on the printed circuit board 18 after the protective elements (20, 21) have been soldered on. This is made possible by an opening 25 which is open towards the printed circuit board and surrounds the protective elements. However, it is also possible to provide a breakthrough for each individual protective element or for individual groups of the protective elements.
Auf der der Frontseite 13 gegenüberliegenden Rückseite der Leiterplatte 18 verläuft eine Erdleiterbahn 26, die mit den Erdleiteranschlüssen der Überspannungsabieiter 20 verbunden ist. Die Erdleiterbahn 26 ist im wesentlichen vom Gehäuseteil 19 raumsparend überdeckt. Sie ist bis in den Stirnseitenbe¬ reich der Leiterplatte 18 geführt und mit einer Erdkontaktfe¬ der 27 verbunden, die sich entlang der Stirnseite der Schutz- baugruppe in deren Steckrichtung bis zur Frontseite (13) er¬ streckt. Beim Einstecken der Steckkontaktstellen 14 in die Steckkontakte 15 des Kontaktbauteils 4 setzt das als Feder- kontakt 28 ausgebildete freie Ende der Erdkontaktfeder 27 auf das metallische Trägerteil auf, das z.B. mit einer Chrom- und/oder Nickelschicht plattiert ist. Dadurch sind die Uber¬ spannungsableiter nach dem Einstecken der Schutzbaugruppe 12 mit der Betriebserde des Verteilergestells verbunden.An earth conductor track 26, which is connected to the earth conductor connections of the surge arresters 20, runs on the rear side of the printed circuit board 18 opposite the front side 13. The earth conductor track 26 is essentially covered by the housing part 19 to save space. It extends up to the end face area of the printed circuit board 18 and is connected to an earth contact spring 27 which extends along the end face of the protective assembly in the plugging direction thereof to the front side (13). When the plug contact points 14 are inserted into the plug contacts 15 of the contact component 4, this acts as a spring Contact 28 formed free end of the earth contact spring 27 on the metallic support member, which is plated with a chrome and / or nickel layer, for example. As a result, the surge arresters are connected to the operating earth of the distributor frame after the protective assembly 12 has been inserted.
Nach den Figuren 5 und 6 sind bei einer anderen Schutzbau¬ gruppe 30 zweipolige Uberspannungsableiter 29 mit ihrer Mit¬ telachse senkrecht zur Leiterplatte 18 angeordnet. Zwischen den Leiterbahnen 23 und den Uberspannungsableitern 29 ist je¬ weils ein Schmelzring 31 eingelegt, der mit einer Seite auf der Leiterbahn 23 aufliegt und mit der anderen Seite an einem Pol des Überspannungsabieiters 29 anliegt. Ein Erdungsblech 31 umklammert die Schutzbaugruppe 30 teilweise und weist freigeschnittene Federzungen 32 auf, die am anderen Pol des Überspannungsabieiters 29 anliegen und diesen gegen den Schmelzring 31 drücken.According to FIGS. 5 and 6, in another protective assembly 30, two-pole surge arresters 29 are arranged with their central axis perpendicular to the printed circuit board 18. Between the conductor tracks 23 and the surge arresters 29, a melting ring 31 is inserted in each case, one side resting on the conductor track 23 and the other side resting on a pole of the surge arrester 29. A grounding plate 31 partially encircles the protective assembly 30 and has cut-out spring tongues 32 which rest on the other pole of the surge arrester 29 and press it against the melting ring 31.
Eine Überspannung auf der Leitung 17 (Figur 2) wird durch den Uberspannungsableiter in das Erdungsblech 31 abgeleitet, wo¬ bei sich der Uberspannungsableiter 29 und der Schmelzring 31 erhitzen. Dieser wird dadurch erweicht, so daß der Uberspan¬ nungsableiter 29 zur Leiterplatte 23 hin gedrückt wird bis er an einem Vorsprung 33 des Erdungsblechε 31 anstößt, so daß die Überspannung nun direkt auf das Erdungsblech 31 übertra¬ gen werden kann.An overvoltage on line 17 (FIG. 2) is dissipated through the overvoltage arrester into the grounding plate 31, whereby the overvoltage arrester 29 and the melting ring 31 heat up. This is softened so that the surge arrester 29 is pressed towards the circuit board 23 until it abuts a projection 33 of the grounding plate 31, so that the overvoltage can now be transmitted directly to the grounding plate 31.
Das Erdungsblech 31 setzt sich an den beiden schmalen Stirn¬ seiten der Schutzbaugruppe 30 einstückig in der Erdkontaktfe- der 27 fort, die sich senkrecht zur Reihenrichtung der Steck¬ kontaktstellen erstreckt und mit ihrem freien Ende in die Einsteckrichtung ragt. The grounding plate 31 continues in one piece on the two narrow ends of the protective assembly 30 in the earth contact spring 27, which extends perpendicular to the row direction of the plug contact points and projects with its free end in the insertion direction.
