- the contact parts 4 end on the side facing away from the receiving chambers 5 in tabs 8 which can be inserted into mating contacts of a distribution strip, not shown.
- These counter contacts are e.g. B. connected to subscriber lines. There is thus an electrical connection between these and the surge arresters 6.
- the surge arresters 6 are arranged in a row in the longitudinal direction of the protective plug 1. In each case, the two end connection pins 7 of the cylindrical surge arrester 6 are contacted with the contact parts 4. The middle pin 7 is connected to the earth plate 3, so that overcurrents occurring in the subscriber lines can be derived to earth.
- the contact parts 4 and the earth plate 3 are designed as fork-shaped spring contacts 9.
- the legs of the spring contacts 9 are cut out of the flat material of the contact parts 4 and can be deflected in the material plane. They dip with their resilient ends into slot-like recesses 10 of an intermediate base 11 of the housing 2.
- the recesses 10 are formed as continuous longitudinal slots that are slightly wider than the diameter of the connecting pins 7. These are guided laterally between the legs of the spring contacts 9 when inserted through centering holes in the intermediate floor 11.
- the strip-shaped earth sheet 3 is inserted and guided in its base in fork-shaped projections 12 of the housing 2.
- the contact parts 4 and the earth plate 3 extend with their Material levels essentially in the longitudinal direction of the protective plug 1, so that it can be kept accordingly narrow.
Abstract
Description
Die Erfindung bezieht sich auf einen Schutzstecker für eine Verteilerleiste in einer Telekommunikations-, insbesondere Fernsprechanlage, wobei der längliche Schutzstecker eine Vielzahl von querstehenden aneinandergereihten Überspannungsableitern aufweist.The invention relates to a protective plug for a distribution strip in a telecommunications, in particular telephone system, the elongated protective plug having a plurality of transversely arranged surge arresters.
Ein derartiger Schutzstecker ist z. B. durch die DE 30 14 796 C2 bekannt geworden. Danach (Figur 3) sind die Anschlußstifte von dreipoligen Überspannungsableitern zwischen die Schenkel von in sich förmig gebogenen Federkontakten eines Schutzsteckers für eine Verteilerleiste einsteckbar. Die Federkontakte sind zum Überspannungsableiter hin offen und ihre Basis ist auf der den Überspannungsableitern abgewandten Seite angeordnet. Zwischen den Federkontakten und den Überspannungsableitern sind im Gehäuse des Schutzsteckers Zentrierbohrungen für die Anschlußstifte angeordnet. Die Federkontakte sind Bestandteil von Kontaktteilen, die in Steckkontaktzungen enden, mit denen der Schutzstecker in eine Verteilerleiste einsteckbar ist. Das Kontaktteil ist in seiner Abwicklung T-förmig ausgebildet) wobei die beiden Seitenschenkel zu den Überspannungsableitern hin gebogen sind.Such a protective plug is such. B. become known from DE 30 14 796 C2. Thereafter (Figure 3), the connecting pins of three-pole surge arresters can be inserted between the legs of spring contacts of a protective plug, which are bent in the shape of an inherent part, for a distributor strip. The spring contacts are open to the surge arrester and their base is arranged on the side facing away from the surge arresters. Centering holes for the connecting pins are arranged in the housing of the protective plug between the spring contacts and the surge arresters. The spring contacts are part of contact parts that end in plug-in contact tongues with which the protective plug can be inserted into a distribution strip. The contact part is T-shaped in its development), the two side legs being bent towards the surge arresters.
Der Erfindung liegt die Aufgabe zugrunde, die Kontaktteile kostengünstig herstellen und einbauen zu können.The invention has for its object to be able to manufacture and install the contact parts inexpensively.
Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Danach können nun die Federschenkel in einem Arbeitsgang mit dem Ausschneiden der Kontaktteile ausgeformt werden. Die Geometrie des Federkontakts ist durch den Schnittstempel genau definiert, so daß stets gleichbleibende Kontaktbedingungen gegeben sind.This object is achieved by the invention according to claim 1. The spring legs can then be shaped in one operation by cutting out the contact parts. The geometry of the spring contact is precisely defined by the cutting punch, so that constant contact conditions are always given.
Beim Einstecken der Anschlußstifte der Überspannungsableiter werden diese seitlich in der schlitzartigen Ausnehmung geführt, so daß sie sicher zwischen die Federschenkel des Federkontakts gelangen. Durch die einfache flache geometrische Gestalt der Federkontakte können diese leichter in das Gehäuse des Schutzsteckers eingesetzt werden, was insbesondere die Automatisierbarkeit der Montage begünstigt.When the connection pins of the surge arresters are inserted, they are guided laterally in the slot-like recess, so that they can get safely between the spring legs of the spring contact. Due to the simple flat geometric shape of the spring contacts, these can be inserted more easily into the housing of the protective plug, which in particular favors the automatability of the assembly.
Nach einer Weiterbildung der Erfindung erstreckt sich die Materialebene der Federkontakte in der Längsrichtung des Schutzsteckers und sind die Freimachungen als durchgehende Längsschlitze ausgebildet. Dadurch kann der Schutzstecker sehr schmal gehalten werden. Eine durchgehende Ausnehmung läßt sich fertigungstechnisch einfach herstellen. Die Kontaktfedern stehen parallel zu den Steckzungen, so daß die Kontaktteile gestreckt oder mit einfachen Biegungen hergestellt werden können.According to a development of the invention, the material plane of the spring contacts extends in the longitudinal direction of the protective plug and the frankings are designed as continuous longitudinal slots. This allows the protective plug to be kept very narrow. A continuous recess can be easily manufactured in terms of production technology. The contact springs are parallel to the tongues, so that the contact parts can be stretched or made with simple bends.
Nach einer anderen Weiterbildung der Erfindung sind die Überspannungsableiter dreipolig ausgebildet, sind die Federkontakte für die mittleren Pole der Überspannungsableiter einstückig mit einem längsdurchgehenden in der Einsteckrichtung stehenden Erdblech verbunden und liegen in dessen Materialebene.According to another development of the invention, the surge arresters are designed with three poles, the spring contacts for the central poles of the surge arresters are connected in one piece to a longitudinally continuous earth plate in the direction of insertion and lie in the material plane thereof.
Ein derartiges Erdblech läßt sich zusammen mit den Federkontakten in einem Stück ausstanzen. Es bedarf keiner Bigungen und läßt sich somit exakt in das Gehäuse des Schutzsteckers einsetzen.Such an earth plate can be punched out in one piece together with the spring contacts. No bends are required and can therefore be inserted exactly into the housing of the protective plug.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing.
