Abstract

The plug (1) has protruding tongues (2) for inertion into the distributor moulding and connection to subscriber lines. The tongues are joined within the plug to spring contacts (3). Transverse three-pole overvoltage divertors (4) are arranged in the longitudinal direction with contact pins (5). Pairs of outer pins are connected to the spring contacts (3) and the central pins to an earth condutor (6) extending over the entire length of the plug (1). Overlapping contacts (7) are slightly angled in opposite directions embracing the central pins. ADVANTAGE - A plug taking up less space is easily mfd. at low cost.

Description

Die Erfindung bezieht sich auf einen Schutzstecker für eine Verteilerleiste in einer Telekommunikationsanlage, wobei der Schutzstecker mit einer Vielzahl von dreipoligen zylindrischen Überspannungsableitern bestückt ist. Ein derartiger Schutz­ stecker ist z. B. durch die DE 30 14 796 C2 bekannt geworden. Danach ist der Schutzstecker mit einer Vielzahl von Steckzungen in eine Verteilerleiste einsteckbar, die Anschlußelemente für ankommende und abgehende Leitungen aufweist. Die Steckzungen sind dann mit einem Teil dieser Anschlußelemente elektrisch verbunden. Die Steckzungen sind mit Steckkontakten verbunden, in die radial abstehende stiftartige Anschlußelemente der drei­ poligen Überspannungsableiter einsteckbar sind. Ein mittleres Anschlußelement ist mit seitlich hochgebogenen Kontaktfedern eines u-förmig gebogenen, in Längsrichtung durchgehenden Erd­ blechs kontaktiert.The invention relates to a protective plug for a Distribution board in a telecommunications system, the Protective plug with a variety of three-pin cylindrical Surge arresters is equipped. Such protection plug is z. B. become known from DE 30 14 796 C2. After that, the protective plug with a variety of tabs can be plugged into a distribution strip, the connection elements for has incoming and outgoing lines. The tongues are then electrical with some of these connection elements connected. The tongues are connected with plug contacts, into the radially protruding pin-like connecting elements of the three pole surge arrester can be inserted. A medium one Connection element is with laterally bent contact springs of a U-shaped earth that is continuous in the longitudinal direction sheet contacted.

Der Erfindung liegt die Aufgabe zugrunde, den Schutzstecker mit geringeren Abmessungen kostengünstig herstellen zu können.The invention is based, with the protective plug to be able to manufacture smaller dimensions inexpensively.

Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Das Erdblech ist nun ein im wesentlichen flaches Blechteil von geringer Breitenabmessung. Da sich die Kontaktlappen in der Längsrichtung erstrecken, kann die Höhe der Erdschiene niedri­ ger gehalten werden. Damit verringern sich die Abmessungen des Schutzsteckers. Das Freistanzen und Ausbiegen der Kontaktlappen kann in einem Vorgang erfolgen, so daß sich die Herstellungsko­ sten entsprechend verringern.This object is achieved by the invention according to claim 1. The earth sheet is now a substantially flat sheet metal part from small width dimension. Since the contact tabs in the Extend longitudinally, the height of the earth rail low be held. This reduces the dimensions of the Protective plug. The punching out and bending out of the contact tabs can be done in one operation, so that the manufacturing Ko reduce accordingly.

Nach einer Weiterbildung der Erfindung sind die freien Endab­ schnitte der Kontaktlappen zur Materialebene hin zurückgebogen. According to a development of the invention, the free endab cuts of the contact tabs bent back to the material level.  

Dadurch werden die Anschlußelemente krallenartig umgriffen und sicher gehalten.As a result, the connection elements are gripped and claw-like kept safe.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.In the following the invention based on one in the drawing illustrated embodiment explained in more detail.

Nach den Fig. 1, 2 und 3 ist ein Schutzstecker 1 mit Steck­ zungen 2 versehen, die in eine Verteilerleiste einsteckbar und mit Teilnehmerleitungen verbindbar sind. Die Steckzungen sind mit Federkontakten 3 im lnneren des Schutzsteckers 1 verbunden. Dieser ist mit querstehenden dreipoligen Überspannungsableitern 4 bestückt, die in seiner Längsrichtung aneinander gereiht sind. Die Überspannungsableiter 4 weisen stiftartige Anschluß­ elemente 5 auf, die an die Elektroden angesetzt sind. Die stirnseitigen Anschlußelemente 5 sind mit den Federkontakten 3 verbunden. Die mittleren der radial abstehenden Anschlußelemen­ te 5 sind mit einem Erblech 6 kontaktiert, das sich über die gesamte Länge des Schutzsteckers erstreckt.According to FIGS. 1, 2 and 3, a protective plug 1 with plug-in tongues 2 is provided which can be connected inserted into a rail and with subscriber lines. The tongues are connected to spring contacts 3 inside the protective plug 1 . This is equipped with transverse three-pole surge arresters 4 , which are lined up in its longitudinal direction. The surge arrester 4 have pin-like connection elements 5 , which are attached to the electrodes. The end connection elements 5 are connected to the spring contacts 3 . The middle of the radially projecting connecting elements te 5 are contacted with a sheet metal 6 , which extends over the entire length of the protective plug.

Das Erdblech 6 weist freigestanzte Kontaktlappen 7 auf, die sich in der Längsrichtung des Erdblechs 3 erstrecken. Für jedes Anschlußelement 5 sind jeweils zwei übereinanderliegende Kon­ taktlappen 7 ausgebildet, die in entgegengesetzter Richtung ra­ gen und sich mit ihren freien Enden überlappen. Die beiden Kon­ taktlappen 7 sind in entgegengesetzter Richtung schräg aus der Materialebene herausgebogen und umgreifen mit ihren freien En­ den diametral das dazwischengesteckte Anschlußelement 5. Dabei ist der Stirnbereich der Kontaktlappen 7 zur Materialebene hin zurückgebogen, so daß das Anschlußelement 5 krallenartig um­ griffen wird.The earth plate 6 has stamped-out contact tabs 7 which extend in the longitudinal direction of the earth plate 3 . For each connecting element 5 , two superimposed con tact tabs 7 are formed, which are in the opposite direction and overlap with their free ends. The two con tact tabs 7 are bent obliquely out of the material plane in the opposite direction and embrace with their free En the diametrically inserted connector element 5th The end region of the contact tab 7 is bent back towards the material level, so that the connecting element 5 is gripped like a claw.
