Description
Im Patent 722 609 ist eine Anordnung für Telefonnetze, in denen außer der niederfrequenten noch eine trägerfrequente Nachrichtenübermittlung erfolgt, insbesondere für Drahtfunkzwecke, vorgeschlagen, bei der auf einfache Weise eine Trennung der Niederfrequenzzuleitung vorgenommen werden soll, ohne daß die Hochfrequenzzuleitung gleichzeitig unterbrochen wird bzw. umgekehrt. Der als Hochpaßfilter und der als Tiefpaßfilter wirkende Teil der Amtsweichen sollenIn patent 722 609 is an arrangement for telephone networks in which, in addition to the low frequency carrier-frequency messaging is still carried out, in particular for Wire radio purposes, proposed, in which a separation of the low-frequency feed line in a simple manner should be carried out without the high-frequency feed line being interrupted at the same time or vice versa. The part of the office switches acting as a high-pass filter and the part of the low-pass filter should
dabei als voneinander getrennte Elemente ausgebildet und von den Adern derart leicht abschaltbar sein, daß durch Herausnehmen eines der Elemente jeweils nur die Niederfrequenzleitung oder die Hochfrequenzleitung abschaltbar ist. Insbesondere sollen die beiden Elemente mit Steckern versehen und' getrennt einsteckbar sein.designed as separate elements and so light from the wires be switched off that by removing one of the elements only the low frequency line or the high-frequency line can be switched off. In particular, the two elements should be provided with connectors and ' can be plugged in separately.
Die Erfindung betrifft eine Verbesserung einer derartigen Anordnung, und es wird vorgeschlagen, die Tiefpaßfilter zu Gruppen vonThe invention relates to an improvement of such an arrangement, and it is proposed that the low-pass filters to groups of
je fünf Filtern zusammenzufassen und in einem gemeinsamen Gehäuse anzuordnen und dabei diese Gruppen von fünf Filtern als steckbare Elemente auszubilden. Es ist bereits vorgeschlagen, die Filter (Hoch- und Tiefpaßfilter) zu einer Einheit zu vereinigen und in den Hauptverteilern anzuordnen. Abgesehen davon, daß keine näheren Angaben darüber gemacht sind, wie die ίο Unterbringung in den Hauptverteilern erfolgen soll, haben diese Anordnungen den Nachteil, daß ein großer Platzbedarf zur Unterbringung der Weichen erforderlich ist. Es ist nämlich hierbei, erforderlich, daß jedes Filter in einem eigenen Gehäuse angeordnet ist. Werden jedoch die Tiefpaßfilter zu Gruppen von fünf Filtern zusammengefaßt, so wird der Platzbedarf bedeutend verringert. Es fallen die zwischen den einzelnen Filtern angeordneten Trennwände fort, und es ist möglich, einen gedrängten Aufbau herbeizuführen. Durch die erfindungsgemäßen Maßnahmen ist es möglich, die Filter sehr klein auszuführen, so daß diese im Fernsprechgestell direkt angeordnet werden können, ohne daß es notwendig ist, besondere Gestelle aufzubauen. Dieses wirkt sich besonders vorteilhaft in Fernsprechämtern aus, in denen zunächst Drahtfunkbetrieb nicht vorgesehen war und nachträglich ausgeführt werden soll. Es ist nämlich durch die erfindungsgemäßen Maßnahmen erreicht, daß keine besonderen baulichen Maßnahmen ergriffen werden müssen, da die Fernsprechgestelle zur Aufnähme der Tiefpässe ausreichen.to summarize five filters and to arrange them in a common housing and to design these groups of five filters as pluggable elements. It is already suggested the filters (High-pass and low-pass filter) to be combined into one unit and to be arranged in the main distributors. Apart from the fact that no further details are given as to how the ίο accommodation in the main distributors takes place should, these arrangements have the disadvantage that a large amount of space is required for accommodation the turnout is required. It is necessary here that each Filter is arranged in its own housing. However, the low-pass filters are too Groups of five filters combined, the space requirement is significantly reduced. The partition walls arranged between the individual filters are no longer necessary, and it is possible to create a compact structure. By the measures according to the invention it is possible to make the filters very small, so that they are in the telephone frame can be arranged directly without the need to build special racks. This is particularly advantageous in telephone exchanges in which wireless operation is not initially provided was and should be carried out afterwards. It is namely by the invention Measures achieved that no special structural measures have to be taken, since the telephone sets for recording the low passes are sufficient.
Vorteilhafterweise liegen die Tiefpaßfilter an sämtlichen Leitungsadern. Es ist nämlich vorteilhaft, sämtlichen Anschlüssen Tiefpaßfilter zuzuordnen, da dann, falls ein Teilnehmer kein Tiefpaßfilter benötigt, keine besonderen Maßnahmen zur Unterbringung der Gruppen nötig sind. In einem derartigen Fall würde es sonst notwendig sein, daß die ganze Gruppe herausgenommen wird und die verbleibenden Anschlüsse mit einzelnen Filtern belegt werden. Dabei würden jedoch die Einzelfilter einen größeren Platzbedarf beanspruchen als die zu je fünf Filtern zusammengefaßten Gruppen.The low-pass filters are advantageously located on all line cores. Because it is advantageous to assign low-pass filters to all connections, since then, if a participant no low-pass filter required, no special measures to accommodate the groups are necessary. In such a case otherwise it would be necessary to remove the whole group and the remaining ones Connections can be assigned individual filters. However, the individual filters would take up more space than the five filters combined Groups.
Eine beispielsweise Ausführung der erfindungsgemäßen Anordnung ist in den Abbildungen dargestellt, und zwar zeigen die Abb. ι einen Hauptverteiler mit in ihm angeordneten Lötösenstreifen und die Abb. 2 und 3 zwei Ansichten eines derartigen Streifens.An example embodiment of the arrangement according to the invention is shown in the figures shown, namely the Fig. ι show a main distributor with arranged in it Solder lug strip and Figs. 2 and 3 show two views of such a strip.
In Abb. ι sind in einem Rahmen V eine Anzahl von Lötösenstreifen L angeordnet, an die die im Telefonvermittlungsamt ankommenden bzw. abgehenden Leitungsadern angeschlossen werden.In Fig. Ι a number of solder lug strips L are arranged in a frame V , to which the incoming and outgoing line wires in the telephone exchange are connected.
Ein derartiger Lötösenstreifen besteht nach Abb. 2 und 3 aus einer Vielzahl von übereinander angeordneten Lötösen 1, die zu einem Streifen zusammengefaßt sind und mit den Trägern 2 des Hauptverteilers verbunden sind. Die zu den einzelnen Leitungen gehörenden Hochpaßfilter 3 sind in gleicher Weise übereinander angeordnet. Sie sind als· einzelne steckbare Elemente ausgebildet, die an einem Handgriff 4 aus ihrem Gehäuse gezogen werden, wodurch eine Auftrennung der Hochfrequenzzuleitung erfolgt. Der Träger 5 der Hochpaßfilter ist seinerseits mit Lötösen 6 versehen, an die jeweils die Zuführungsleitungen für die ankommende und abgehende Hochfrequenz angeschlossen werden.According to Fig. 2 and 3, such a solder lug strip consists of a large number of one on top of the other arranged solder lugs 1, which are combined into a strip and with the Beams 2 of the main distributor are connected. Those belonging to the individual lines High-pass filters 3 are arranged one above the other in the same way. You are as an individual Pluggable elements are formed, which are pulled out of their housing on a handle 4 which results in a separation of the high-frequency feed line. The carrier 5 the high-pass filter is in turn provided with soldering lugs 6, to each of which the supply lines for the incoming and outgoing radio frequency.
Um nun die Tiefpaßfilter auf einem möglichst kleinen Raum unterzubringen, sind diese zu je fünf in einem gemeinsamen Gehäuse zusammengefaßt. Dieses die Tiefpaßfilter enthaltende Gehäuse ist mit Steckern versehen und wird in den Kasten 7 eingesetzt, der entsprechende Buchsen besitzt und außerdem mit Lötösen versehen ist, an die die zugehörigen Leitungen angeschlossen sind. Es läßt sich durch die erfindungsgemäße Ausbildung erreichen, daß die Unterbringung im Hauptverteiler ohne wesentlich größeren Raumbedarf als bei normalen Anordnungen ohne Hochfrequenzzuführung erfolgt.In order to accommodate the low-pass filters in the smallest possible space, are five of these are combined in a common housing. This the low-pass filter containing housing is provided with plugs and is inserted into the box 7, which has the corresponding sockets and is also provided with soldering lugs to which the associated Lines are connected. It can be through the inventive training achieve that the accommodation in the main distributor without much larger space requirements than with normal arrangements takes place without high frequency feed.
In der beispielsweisen Ausführungsform, bei der zwanzig Leitungsadern an einem Lötösenstreifen angeordnet sind, werden je fünf Tiefpaßfilter in einem gemeinsamen Kasten angeordnet, so daß vier Kästen vorhanden sind.In the exemplary embodiment, in which there are twenty leads on one solder lug strip are arranged, five low-pass filters are arranged in a common box, so that four boxes are available are.
