Description

Die Erfindung bezieht sich auf eine Anschlußleiste für hohe Übetragungsraten in der Telekommunikations- und Datentechnik, aus einem Kunststoffkörper mit in mindestens einer Reihe angeordneten Kammern für Schneidklemm-Kontaktelemente und mit in den Querwänden zwischen den Kammern angeordneten, achsparallel zu diesen verlaufenden Schlitzen für Schirmbleche.The invention relates to a terminal block for high transmission rates in telecommunications and data technology, made of a plastic body with chambers arranged in at least one row for Insulation displacement contact elements and with slots for shield plates arranged in the transverse walls between the chambers and running axially parallel to these.

Eine Anschlußleiste der gattungsgemäßen Art ist aus der US-PS 5,160,273 vorbekannt. Hierbei soll das Problem des Über- bzw. Nebensprechens über die an benachbarte Schneidklemm-Kontaktelemente angeschlossenen Kabeladern durch Einsetzen einer Vielzahl elektrisch leitfähiger Abschirmbleche zwischen die einzelnen Paare von Schneidklemm-Kontaktelementen gelöst werden. Das Problem des Über- bzw. Nebensprechens tritt bei der Übertragung großer Informationsvolumen über elektrische Leitungen auf, wobei die Informationen bei hohen Frequenzen übertragen werden. Die Übertragung bei derart hohen Frequenzen erzeugt eine Strahlung und eine Interferenz zwischen benachbarten Kabeladern, insbesondere wenn diese Kabeladern eng benachbart zueinander in der Anschlußleiste angeordnet sind. Durch das Einsetzen der elektrisch leitfähigen Schirmbleche wird eine größere Über- bzw. Nebensprechdämpfung bei hohen Übertragungsraten erzielt.A terminal block of the generic type is previously known from US Pat. No. 5,160,273. In this case, the problem of crosstalk or crosstalk via the cable wires connected to adjacent insulation displacement contact elements is to be solved by inserting a large number of electrically conductive shielding plates between the individual pairs of insulation displacement contact elements. The problem of crosstalk or crosstalk arises when large amounts of information are transmitted via electrical lines, the information being transmitted at high frequencies. The transmission at such high frequencies generates radiation and interference between adjacent cable cores, especially if these cable cores are arranged closely adjacent to one another in the terminal block. By using the electrically conductive shield plates, greater crosstalk or crosstalk attenuation is achieved at high transmission rates.

Die bekannte Anschlußleiste umfaßt zwei parallele Reihen von Kammern für Schneidklemm-Kontaktelemente, denen jeweils ein Schirmblech zugeordnet ist, wobei die gegenüberliegenden Schirmbleche der beiden Reihen durch ein großflächiges Verbindungsblech miteinander verbunden sind, das in das zugehörige Unterteil der Anschlußleiste eingesetzt ist. Der Einsatz von großflächigen, elektrisch leitfähigen Abschirmblechen in den Anschlußleisten erfordert jedoch eine Vergrößerung des Bauvolumens der Anschlußleisten und einen höheren Kostenaufwand bei der Herstellung der Anschlußleisten.The known terminal block comprises two parallel rows of chambers for insulation displacement contact elements, to each of which a shield plate is assigned, the opposite shield plates of the two rows being connected to one another by a large-area connecting plate which is inserted into the associated lower part of the terminal strip. However, the use of large-area, electrically conductive shielding plates in the terminal strips requires an enlargement the volume of the terminal strips and a higher cost in the manufacture of the terminal strips.

Der Erfindung liegt von daher die Aufgabe zugrunde, eine Anschlußleiste zu schaffen, bei welcher mit der Anordnung von besonders ausgeformten Schirmblechen eine effektive Verminderung des Über- und Nebensprechens und eine wesentliche Vereinfachung der Montage sowohl der Schirmbleche als auch der Kabeladern an den Schneidklemm-Kontaktelementen gewährleistet sind.The invention is therefore based on the object to provide a terminal block in which the arrangement of specially shaped shield plates ensures an effective reduction in cross-talk and crosstalk and a substantial simplification of the assembly of both the shield plates and the cable cores on the insulation displacement contact elements are.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Kammern einer Anschlußeinheit mit geringstmöglichem Abstand voneinander im Kunststoffkörper angeordnet und die Schlitze zur Aufnahme der Schirmbleche in der dickeren Querwand zwischen jeweils zwei benachbarten Anschlußeinheiten von der Unterseite her ausgebildet sind. Hierdurch ist es möglich, mittels nur zweier Schirmbleche ein Paar von in mit geringem Abstand voneinander im Kunststoffkörper angeordneten Kammern, die eine Anschlußeinheit bilden, abzuschirmen. Der größere Abstand zwischen den Kammern benachbarter Anschlußeinheiten verringert die Gefahr des Über- und Nebensprechens.To achieve this object, the invention provides that the chambers of a connection unit are arranged at the smallest possible distance from one another in the plastic body and the slots for receiving the shielding plates are formed in the thicker transverse wall between two adjacent connection units from the bottom. This makes it possible to shield a pair of chambers which are arranged at a short distance from one another in the plastic body and form a connection unit by means of only two shielding plates. The greater distance between the chambers of adjacent connection units reduces the risk of crosstalk and crosstalk.

Die Schirmbleche weisen nach einer bevorzugten Ausführungsform im oberen Bereich eine Rastöffnung auf, die mit einer Rastnase im Kunststoffkörper beim Stecken des Schirmbleches in die Anschlußleiste verrastet. Die Schirmbleche werden von der Unterseite der Anschlußleiste gesteckt. Weiterhin weisen die Schirmbleche im Bereich des Kontaktpins einen Ausschnitt auf, über den eine günstige Leiterführung erfolgt. Die Übertragungswerte werden durch einen durch diese Maßnahme günstig beeinflußten Magnetfeldaufbau verbessert. Die Schirmbleche werden über die Kontaktpins und über einen Leiterzug beispielsweise auf einer Leiterplatte miteinander verbunden.According to a preferred embodiment, the shield plates have a latching opening in the upper region, which latches with a latch in the plastic body when the shield plate is inserted into the terminal block. The shield plates are inserted from the underside of the terminal block. Furthermore, the Shield plates in the area of the contact pin on a cutout, through which a cheap conductor routing takes place. The transmission values are improved by a magnetic field structure favorably influenced by this measure. The shield plates are connected to one another via the contact pins and a conductor track, for example on a circuit board.

Die in einer bevorzugten Ausführungsform vorgesehene erfindungsgemäße Ausformung des Kabelader-Einführungsbereiches der Schneidklemm-Kontaktelemente ermöglicht einen leichteren Anschluß von Kabeladern, indem die von Hand eingelegten Kabeladern vor dem Eindrücken mit einem Werkzeug zuverlässig über die Noppen im Einführungsbereich fixiert werden.The inventive design of the cable core insertion area of the insulation displacement contact elements, according to the invention, enables an easier connection of cable wires by reliably fixing the cable wires inserted by hand before pressing them in with a tool via the knobs in the insertion area.

Nach einer weiteren Ausführungsform können die Schirmbleche mindestens einer Kammer durch schmale Stege miteinander verbunden sein, die in Nuten im Boden des Kunststoffkörpers eingesetzt sind. Diese Ausbildung der Schirmbleche ermöglicht einen technisch und kostenmäßig wenig aufwendigen Einbau der Schirmbleche unmittelbar in das Oberteil der Anschlußleiste, so daß die Anordnung der erfindungsgemäßen Schirmbleche auch bei Aderverbindern möglich ist, die aus nur einer einzigen Reihe von Kammern für Schneidklemm-Kontaktelemente bestehen und kein Unterteil aufweisen.According to a further embodiment, the shield plates can be connected to one another in at least one chamber by narrow webs which are inserted into grooves in the bottom of the plastic body. This design of the shield plates allows a technically and cost-less installation of the shield plates directly into the upper part of the terminal block, so that the arrangement of the shield plates according to the invention is also possible with wire connectors that consist of only a single row of chambers for insulation displacement contact elements and no lower part exhibit.

Ferner können drei Schirmbleche zweier benachbarter Paare von Kammern durch schmale Stege miteinander zu einem Schirmblechkäfig verbunden werden. Dabei weisen die drei Schirmbleche und die diese verbindenden schmalen Stege in der Ebene der Stege eine aus sieben kurzen Blechstreifen gebildete Achtform auf.Furthermore, three shield plates of two adjacent pairs of chambers can be connected to one another by a narrow web to form a shield plate cage. Show the three shield plates and the narrow webs connecting them in the plane of the webs have an eight shape formed from seven short metal strips.

In besonders bevorzugter Weise sind in der Querwand zwischen zwei Paaren eng benachbarter Kammern jeweils ein Schlitz und in der Querwand zwischen jeweils zwei Paaren von dicht nebeneinander angeordneten Kammern je zwei Parallele Schlitze zur Aufnahme der Schirmbleche angeordnet. Hierdurch wird eine besonders kompakte Bauweise insbesondere eines Aderverbinders ermöglicht.In a particularly preferred manner, one slot each is arranged in the transverse wall between two pairs of closely adjacent chambers and two parallel slots each for receiving the shield plates are arranged in the transverse wall between two pairs of closely arranged chambers. This enables a particularly compact design, in particular of a wire connector.

Durch die paarweise Anordnung der Kammern mit geringem Abstand voneinander in einer Reihe des Kunststoffkörpers wird die Übersprechdämpfung der in diese Kammern eingesetzten Schneidklemm-Kontaktelemente noch wesentlich verbessert, zumal der Abstand eines jeden Paares eng benachbarter Kammern eines Anschlußelementes zum benachbarten Paar eines weiteren Anschlußelementes größer ist als der Abstand zwischen den eng benachbarten Kammern. Hierdurch werden die Kapazitäten benachbarter Paare von in einer Reihe angeordneten Schneidklemm-Kontaktelementen weiter verringert und die Neben- bzw. Übersprechwerte noch weiter verbessert.Due to the paired arrangement of the chambers with a small distance from each other in a row of the plastic body, the crosstalk attenuation of the insulation displacement contact elements used in these chambers is significantly improved, especially since the distance between each pair of closely adjacent chambers of a connecting element to the adjacent pair of another connecting element is greater than the distance between the closely adjacent chambers. As a result, the capacities of adjacent pairs of insulation displacement contact elements arranged in a row are further reduced and the cross-talk or crosstalk values are further improved.

Entsprechend der Darstellung in der Fig.1 wird die Anschlußleiste aus einem Kunststoffkörper 1 gebildet, der vier Anschlußeinheiten 26 mit jeweils zwei im Abstand d angeordneten Kammern 2 umfaßt. Die Kammern 2 sind von der Oberseite 5 der Leiste gebildet und dienen der Aufnahme von Schneidklemm-Kontaktelementen 28. Jedes Paar Kammern 2 einer Anschlußeinheit 26 wird durch eine Querwand 27 begrenzt, in der von der Unterseite 23 ein Schlitz 25 zum Einstecken eines Schirmbleches 24 mit einem Kontaktpin 32 angeordnet ist. Der Abstand d zwischen den Kammern 2 einer Anschlußeinheit 26 ist wesentlich geringer als der Abstand D zwischen den Kammern 2 benachbarter Anschlußeinheiten 26. Der Abstand D beträgt mindestens das 1,5-fache des Abstands d. Jede Anschlußeinheit 26 besteht aus einem Paar Kammern 2 mit den Schneidklemm-Kontaktelementen 28 und einem Schirmblech 24. Das in der Fig. 1 links herausgezogen dargestellte Schirmblech 24 ist nur notwendig, wenn eine weitere Leiste angereiht wird. Die Anschlußleiste kann auch aus für jede Anschlußeinheit 26 separaten Kunststoffkörper-Baueinheiten gebildet sein, die zu einer beliebigen Anzahl von Anschlußeinheiten 26 zusammengereiht werden. Die Kunststoffkörper 1 können mit den Stirnseiten 37 entweder glatt oder über Rastelemente aneinandergereiht werden.According to the representation in FIG. 1, the connection strip is formed from a plastic body 1, which comprises four connection units 26, each with two chambers 2 arranged at a distance d. The chambers 2 are formed by the top 5 of the bar and serve to accommodate insulation displacement contact elements 28. Each pair of chambers 2 of a connection unit 26 is delimited by a transverse wall 27, in which a slot 25 for inserting a shielding plate 24 from the bottom 23 a contact pin 32 is arranged. The distance d between the chambers 2 of a connection unit 26 is significantly smaller than the distance D between the chambers 2 of adjacent connection units 26. The distance D is at least 1.5 times the distance d. Each connection unit 26 consists of a pair of chambers 2 with the insulation displacement contact elements 28 and a shield plate 24. The shield plate 24 shown on the left in FIG. 1 is only necessary if a further strip is attached. The terminal block can also be formed from separate plastic body assemblies for each connection unit 26, which are arranged in any number of connection units 26. The plastic body 1 can be either smooth or with locking elements with the end faces 37 to be strung together.

In der Fig. 2 wird mit der Seitenansicht der Anschlußleiste die Lage der Schneidklemm-Kontaktelemente 28 im Kunststoffkörper 1 und die räumliche Ausbildung der einzelnen Anschlußeinheiten 26 sowie der Abstände d zwischen den Kammern 2 einer Anschlußeinheit 26 und zu den benachbarten Anschlußeinheiten 26 gezeigt. Die Schneidklemm-Kontaktelemente 28 sind von der Oberseite 5 der Anschlußleiste zugänglich.2 shows the side view of the terminal strip, the position of the insulation displacement contact elements 28 in the plastic body 1 and the spatial design of the individual connection units 26 and the distances d between the chambers 2 of a connection unit 26 and the adjacent connection units 26. The insulation displacement contact elements 28 are accessible from the top 5 of the terminal block.

Nach der Darstellung in der Fig. 6 weisen die Schneidklemm-Kontaktelemente 28 einen Einführungsbereich 29 für nicht dargestellte Kabeladern auf, der aus gegenüberstehenden Noppen 30 gebildet wird, die eine kreisförmige Ausweitung 31 nach oben abschließen. Dadurch wird eine von Hand in die Ausweitung 31 eingelegte Kabelader vorfixiert und kann nachfolgend problemlos mit einem geeigneten Werkzeug in den Klemmschlitz 6 eingedrückt werden.According to the illustration in FIG. 6, the insulation displacement contact elements 28 have an insertion region 29 for cable cores (not shown), which is formed from opposing knobs 30 which terminate a circular expansion 31 at the top. As a result, a cable core inserted by hand into the expansion 31 is pre-fixed and can subsequently be easily pushed into the clamping slot 6 using a suitable tool.
