Abstract

A cover (5) for closing retaining chambers (3) for overvoltage suppressors (4) of a protector connector (1) is curved convexly in the form of an arc towards the retaining chambers and is constructed in a resiliently elastic manner. The cover (5) is anchored at both ends to the protector connector (1) and in this case rests flush on the protector connector (1). In consequence, the protector connector can be of narrow design and can be easily opened and closed. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Schutzstecker für eine Verteilerleiste in einer Telekommunikations-, insbesondere Fernsprechanlage, wobei der längliche Schutzstecker mit Steckzungen versehen ist, die mit Steckkontakten der Verteilerleiste kontaktierbar sind.The invention relates to a protective plug for a distribution strip in a telecommunications, in particular telephone system, the elongated protective plug being provided with tongues which can be contacted with plug contacts of the distribution strip.

Ein derartiger Schutzstecker ist z. B. durch die DE 30 14 796 C2 bekannt geworden. Danach sind die Steckzungen über Kontaktteile mit Überspannungsableitern verbunden, die in Aufnahmekammern des Schutzsteckers eingesetzt sind. Die Gegenpole der Überspannungsableiter sind mit Erde verbunden. Die Kontaktbauteile der Verteilerleisten sind z. B. mit Teilnehmerleitungen verbunden. Dadurch können in diesen auftretende Überspannungen gegen Erde abgeführt werden.Such a protective plug is such. B. become known from DE 30 14 796 C2. Thereafter, the tongues are connected via contact parts to surge arresters, which are inserted in the receiving chambers of the protective plug. The opposite poles of the surge arresters are connected to earth. The contact components of the distribution strips are e.g. B. connected to subscriber lines. This allows excess voltages to be dissipated against earth.

Die Überspannungsableiter sind von der den Steckzungen abgewandten Seite her in die Aufnahmekammern einsetzbar. Diese sind damit für die üblichen Wartungsarbeiten gut zugänglich.The surge arresters can be inserted into the receiving chambers from the side facing away from the tongues. This makes them easily accessible for normal maintenance work.

Zum Zwecke des Berührungsschutzes ist es jedoch wünschenswert, die Aufnahmekammern mit einem Deckel zu verschließen.For the purpose of protection against contact, however, it is desirable to close the receiving chambers with a cover.

Der Erfindung liegt die Aufgabe zugrunde, den Deckel so auszubilden und anzubringen, daß die Aufnahmekammern des Schutzsteckers leicht geöffnet werden können.The invention has for its object to design and attach the lid so that the receiving chambers of the protective plug can be easily opened.

Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Ein derartiger Deckel kann einfach auf die Bedienungsseite des Schutzsteckers aufgelegt werden. Die Vorspannung, die Dicke und die Federeigenschaften des Deckels können so aufeinander abgestimmt werden, daß er sich glatt an den Schutzstecker anschmiegt. Eine Verrastung in der Mitte des Schutzsteckers ist daher nicht erforderlich. Das bedeutet, daß die Gesamtbreite des Schutzsteckers mit dem Deckel nicht für längsseitige Haltemittel vergrößert werden muß. Dies führt wiederum dazu, daß die Verteilerleiste entsprechend schmal gehalten werden kann, so daß sich die gesamte Einbaubreite verringert. Die Maßnahmen zur Verankerung an den Stirnseiten erhöhen jedoch nicht die Baulänge des Schutzsteckers. Die Vorspannung kann beispielsweise dadurch erzielt werden, daß die Bedienungsseite des Schutzsteckers in seiner Längsrichtung ein konvexe Krümmung aufweist.This object is achieved by the invention according to claim 1. Such a cover can simply be placed on the operating side of the protective plug. The pretension, the thickness and the spring properties of the lid can thus be coordinated be that it hugs the protective plug smoothly. A latching in the middle of the protective plug is therefore not necessary. This means that the total width of the protective plug with the cover does not have to be increased for the longitudinal holding means. This in turn leads to the distributor strip being able to be kept correspondingly narrow, so that the overall installation width is reduced. However, the measures for anchoring on the end faces do not increase the overall length of the protective plug. The pretension can be achieved, for example, in that the operating side of the protective plug has a convex curvature in its longitudinal direction.

Da zum Anlegen des Deckels keine hohe Kraft erforderlich ist, können die Verankerungsmittel entsprechend dünn und leicht lösbar z. B. als Rastnasen ausgebildet werden. Dies erleichtert das Öffnen und Schließen des Deckels. Die Rastmittel können in der Längsrichtung des Schutzsteckers wirken und dabei die Biegsamkeit des Deckels nutzen.Since no high force is required to put on the cover, the anchoring means can be correspondingly thin and easily detachable, e.g. B. be designed as locking lugs. This makes opening and closing the lid easier. The locking means can act in the longitudinal direction of the protective plug and use the flexibility of the cover.

Vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 4 gekennzeichnet:Advantageous developments of the invention are characterized in claims 2 to 4:

Durch die Weiterbildung nach Anspruch 2 kann die Oberseite des Schutzsteckers gerade bleiben, so daß alle Kammern gleich sind und alle Überspannungsableiter unter den selben geometrischen Bedingungen ausgewechselt werden können. Dies erleichtert die Bedienungsarbeiten. Der Deckel kann in einfacher Weise z. B. in einer entsprechenden gekrümmten Spritzgußform hergestellt werden. Es ist aber auch möglich, den Deckel in geraden Spritzgußformen herzustellen und die Krümmung durch besondere gießtechnische Maßnahmen z. B. hinsichtlich der Angußstellen zu erzeugen. Außerdem kann auch ein geradlinig gespritzter Deckel nachträglich durch Verformung mit der vorgesehenen Krümmung versehen werden.Through the development according to claim 2, the top of the protective plug can remain straight, so that all chambers are the same and all surge arresters can be replaced under the same geometric conditions. This simplifies the operating work. The lid can be z. B. in a corresponding curved injection mold. But it is also possible to produce the lid in straight injection molds and the curvature by special casting measures such. B. with respect to the gate. In addition, a rectilinearly molded cover can subsequently be provided with the intended curvature by deformation.

Durch die Weiterbildung nach Anspruch 3 ist es möglich, den Deckel einfach auf den Schutzstecker aufzuschnappen. Ebenso einfach kann er dadurch gelöst werden, daß man ihn im mittleren Bereich des Schutzsteckers hochzieht, so daß die Verrastung an der Stirnseite gelöst wird. Das Hochziehen läßt sich in einfacher Weise mit den bloßen Fingern bewerkstelligen, ohne daß zur Entriegelung ein Werkzeug erforderlich ist. Dadurch werden die Kontroll- und Bedienungsarbeiten erheblich erleichtert.Through the training according to claim 3, it is possible Simply snap the cover onto the protective plug. It can be released just as easily by pulling it up in the middle area of the protective plug, so that the catch on the front side is released. The pulling up can be accomplished in a simple manner with the bare fingers, without the need for a tool for unlocking. This considerably simplifies the control and operating work.

Durch die Weiterbildung nach Anspruch 4 ist der Deckel unverlierbar am Schutzstecker gehalten und geführt. Dadurch können die Aufnahmekammern für die Überspannungsableiter durch einfaches Zuklappen des Deckels wieder geschlossen werden.Through the development according to claim 4, the lid is held and guided captively on the protective plug. As a result, the receiving chambers for the surge arresters can be closed again by simply closing the cover.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing.

Figur 1 und 2 zeigen in einer Seitenansicht und einer Draufsicht einen Schutzstecker 1 mit Steckzungen 2, die mit Kontaktteilen einer entsprechenden Verteilerleiste kontaktierbar sind. Auf der den Steckzungen abgewandten Seite weist der Schutzstecker 1 eine sich in seiner Längsrichtung erstreckende Reihe von Aufnahmekammern 3 für Überspannungsableiter 4 auf, die mit den Steckzungen 2 elektrisch verbunden sind. Die Aufnahmekammern 3 sind durch einen Deckel 5 verschließbar.Figures 1 and 2 show a side view and a plan view of a protective plug 1 with tongues 2, which can be contacted with contact parts of a corresponding distributor strip. On the side facing away from the tongues, the protective plug 1 has a row of receiving chambers 3 for surge arresters 4 which extend in its longitudinal direction and which are electrically connected to the tongues 2. The receiving chambers 3 can be closed by a cover 5.

Dieser ist federelastisch ausgebildet und im geöffneten Zustand in sich zum Schutzstecker 1 hin konvex gekrümmt. Er ist auf einer Stirnseite mit einer angespritzten Schwenkachse 6 versehen, die im Gehäuse des Schutzsteckers 1 verrastet und schwenkbar gelagert ist. Auf der anderen Stirnseite ist an dem flachen dünnen Deckel eine nach außen weisende Rastnase 7 vorgesehen, die im geschlossenen Zustand eine entsprechende stirnseitige Außenwand 8 des Schutzsteckers 1 von innen her hintergreift. Beim Zuklappen des Deckels 5 schmiegt sich dieser auf Grund der negativen Vorspannungen flach an die Oberseite des Schutzsteckers 1 an, so daß die Aufnahmekammern 3 berührungssicher verschlossen werden können.This is designed to be resilient and, in the open state, is convexly curved toward the protective plug 1. It is provided on one end face with a molded swivel axis 6, which is locked in the housing of the protective plug 1 and is pivotably mounted. On the other end, an outward-facing latching lug 7 is provided on the flat, thin cover, which in the closed state engages behind a corresponding end-side outer wall 8 of the protective plug 1 from the inside. When the cover 5 is closed, it nestles flat against the top of the protective plug 1 due to the negative prestressing, so that the receiving chambers 3 can be closed in a contact-safe manner.

Zum Öffnen wird der Deckel 5 etwa in der Mitte des Schutzsteckers 1 seitlich angefaßt und in der Richtung des angegebenen Pfeiles hochgezogen. Dabei biegt er sich entsprechend den strichpunktierten Linien. Dadurch wird die Rastnase 7 in die Richtung der anderen Stirnseite gezogen und die Verrastung gelöst. Der Deckel kann nun durch einfaches Aufklappen geöffnet werden.To open the cover 5 is touched approximately in the middle of the protective plug 1 and pulled up in the direction of the arrow indicated. It bends according to the dash-dotted lines. As a result, the locking lug 7 is pulled in the direction of the other end face and the locking is released. The lid can now be opened by simply opening it.
