Description

Die Erfindung bezieht sich auf eine Anschlußleiste mit zwei Reihen von Schneid-Klemm-Kontakten zum Anschluß von isolierten Kabeladern gemäß dem Oberbegriff des Anspruches 1.The invention relates to a terminal block with two rows of insulation displacement contacts for connecting insulated cable wires according to the preamble of claim 1.

Eine Anschlußleiste dieser Art ist aus der DE-PS 28 11 812 vorbekannt. Bei dieser Anschlußleiste sind zwei parallele Reihen von Schneid-Klemm-Kontakten vorgese­hen, die zum Anschluß von isolierten Kabeladern dienen. Zum Schutz vor Überspannungen dieser Kabeladern ist in diese Anschlußleiste ein Überspannungsableitermagazin von oben einsteckbar. Am Überspannungsableitermagazin angeordnete Kontaktzungen werden hierbei mit den Schneid-Klemm-Kontakten verbunden. Die Kontaktzungen sind mit den im Gehäuse des Überspannungsmagazins ange­ordneten Überspannungsableitern verbunden. Nachteilig bei dieser Anschlußleiste ist, daß die Schneid-Klemm-­Kontakte vollständig durch das Überspannungsableiter­magazin abgedeckt und somit nicht mehr zugänglich sind. Ein Entfernen der angeschlossenen Kabeladern bzw. ein Beschalten noch freier Kontaktelemente ist nur nach Ziehen des Überspannungsableitermagazins möglich. Darüber hinaus sind auch Funktionsprüfungen der ange­schlossenen Kabeladern mittels Prüfstecker nur nach Ziehen des Überspannungsableitermagazins durchführbar. Ein weitere Nachteil besteht darin, daß eine derartige Anordnung aufgrund seiner baulichen Höhe ein entsprec­hend großes Gehäuse zum Einbau von mit Überspannungs­ableitern bestückten Anschlußleisten benötigt.A terminal block of this type is previously known from DE-PS 28 11 812. This terminal block has two parallel rows of insulation displacement contacts that are used to connect insulated cable wires. To protect against overvoltages of these cable cores, an overvoltage arrester magazine can be inserted into this terminal block from above. Contact tongues arranged on the surge arrester magazine are connected to the insulation displacement contacts. The contact tongues are connected to the surge arresters arranged in the housing of the overvoltage magazine. A disadvantage of this terminal block is that the insulation displacement contacts are completely covered by the surge arrester magazine and are therefore no longer accessible. Removing the connected cable wires or connecting free contact elements is only possible after pulling out the surge arrester magazine. In addition, functional tests of the connected cable cores using test plugs can only be carried out after pulling out the surge arrester magazine. Another disadvantage is that, due to its structural height, such an arrangement requires a correspondingly large housing for the installation of terminal strips equipped with surge arresters.

Aus der PS 35 09 523 ist eine weitere Anschlußleiste mit zwei Reihen von Schneid-Klemm-Kontakten und einem mit der Anschlußleiste verbindbaren Überspannungsab­leitermagazin bekannt. Auch hier wird eine Reihe von Schneid-Klemm-Kontakten vollständig von dem Magazin abgedeckt, so daß die dort angschlossenen Kabeladern nicht zugänglich sind.From PS 35 09 523 a further terminal block with two rows of insulation displacement contacts and a surge arrester magazine which can be connected to the terminal block is known. Here, too, a series of insulation displacement contacts is completely covered by the magazine, so that the cable wires connected there are not accessible.

Der Erfindung liegt von daher die Aufgabe zugrunde, eine Anschlußleiste mit einem Überspannungsschutz zu schaffen, welche ein Be- und Entschalten und ein Prüfen und Testen der angeschlossenen Kabeladern an den Schneid-Klemm-Kontakten auch bei eingesetztem Überspan­nungsschutz zuläßt, wobei die baulichen Abmessungen der Anschlußleiste so ausgebildet sein sollen, daß die An­schlußleiste auch in flache Gehäusekörper einsetzbar ist.The invention is therefore based on the object to provide a terminal block with overvoltage protection, which allows switching on and off and testing and testing the connected cable wires on the insulation displacement contacts even when overvoltage protection is used, the structural dimensions of the terminal block should be designed so that the terminal block can also be used in flat housing bodies.

Die Lösung dieser Aufgabe ergibt sich aus den kenn­zeichnenden Merkmalen des Patentanspruches 1. Die An­schlußleiste ist derart ausgebildet, daß die beiden Reihen von Schneid-Klemm-Kontakten auf verschiedenen Seiten des Anschlußleiste angeordnet sind und daß das Überspannungsableitermagazin seitlich ungefähr mittig zwischen den beiden Reihen von Schneid-Klemm-Kontakten angeordnet ist. Hieraus ergibt sich eine vorteilhafte, sehr platzsparende Anordnung. Die Schneid-Klemm-Kon­takte beider Reihen sind auch nach dem Stecken des Überspannungsableitermagazins frei zugänglich, so daß sowohl ein Be- als auch ein Entschalten der dort ange­schlossenen Kabeladern möglich ist. Auch ein Prüfen und Testen der Leitungsverbindung mittels Prüfeinrichtungen ist möglich.The solution to this problem results from the characterizing features of claim 1. The terminal block is designed such that the two rows of insulation displacement contacts are arranged on different sides of the terminal block and that the surge arrester magazine laterally approximately in the middle between the two rows of cutting -Klemm contacts is arranged. This results in an advantageous, very space-saving arrangement. The insulation displacement contacts of both rows are freely accessible even after the surge arrester magazine has been plugged in, so that the cable wires connected there can be switched on and off. It is also possible to test and test the line connection using test equipment.

Weitere vorteilhafte Ausgestaltungen der Erfindung er­geben sich aus den Unteransprüchen. Hierbei wird ins­ besondere auf die vorteilhafte Anordnung der Kammer- gemäß Anspruch 11 hingewiesen, durch die ein Vergießen der an der unteren Reihe von Schneid-Klemm-Kontakten angeschlossenen Kabeladern möglich ist.Further advantageous embodiments of the invention result from the subclaims. Here is ins particularly pointed out to the advantageous arrangement of the chamber according to claim 11, by which a potting of the cable wires connected to the lower row of insulation displacement contacts is possible.

Aus der DE-PS 29 43 578 ist zwar eine Anschlußleiste mit entgegengesetzten Reihen von Anschlußkontakten be­kannt, jedoch ist hier kein Überspannungsschutz vor­gesehen.From DE-PS 29 43 578 a terminal block with opposite rows of contacts is known, but no surge protection is provided here.

Die Erfindung ist nachfolgend anhand von drei Ausfüh­rungsbeispielen von Anschlußleisten näher erläutert.The invention is explained in more detail below using three exemplary embodiments of terminal strips.

Die in den Figuren dargestellte Anschlußleiste 1 be­steht aus einem aus Kunststoff hergestellten Leisten­körper, aus einem Oberteil 28 und einem Unterteil 29. Seitlich an der Anschlußleiste 1 ist ein von oben ein­steckbares Überspannungsableitermagazin 10 angeordnet. In der Anschlußleiste 1 sind Schneid-Klemm-Kontakte 4 gelagert, die zum Anschluß von nicht dargestellten isolierten Kabeladern oder von papierisolierten Kabel­adern vorgesehen sind. Die Schneid-Klemm-Kontakte 4 bestehen in bekannter Weise aus einem metallischem Werkstoff und sind mit einem Kontaktschlitz 30 versehen, in die eine isolierte Kabelader mittels eines nicht dargestellten Werkzeuges eingedrückt wird. Beim Eindrücken der Kabelader in den Kontaktschlitz 30 wird die Isolation der Kabelader durchschnitten und eine Kontaktverbindung zwischen dem leitenden Kern der Kabelader und dem Schneid-Klemm-Kontakt hergestellt. Mehrere Schneid-Klemm-Kontakte 4 sind hintereinander in einer ersten Reihe 12 angeordnet. Die nebeneinander angeordneten Schneid-Klemm-Kontakte 4 sind durch Klemmstege 31 voneinander getrennt, wie es in Fig. 4 dargestellt ist. Zu dieser ersten Reihe 12 von Schneid-Klemm-Kontakten 4 ist auf der entgegengesetzten Seite eine zweite Reihe 13 von Schneid-Klemm-Kontakten 4 angeordnet. Wie es in Fig. 1 dargestellt ist, ist die erste Reihe 12 von Schneid-Klemm-Kontakten 4 an der Oberseite 14 und die zweite Reihe 13 von Schneid-Klemm-Kontakten 4 an der Unterseite 15 der Anschlußleiste 1 angeordnet.The terminal block 1 shown in the figures consists of a strip body made of plastic, an upper part 28 and a lower part 29. A surge arrester magazine 10 which can be inserted from above is arranged on the side of the terminal block 1. In the terminal block 1 insulation displacement contacts 4 are mounted, which are provided for connecting insulated cable wires, not shown, or paper-insulated cable wires. The insulation displacement contacts 4 consist in a known manner of a metallic material and are provided with a contact slot 30 into which an insulated cable core is pressed by means of a tool, not shown. When the cable core is pressed into the contact slot 30, the insulation of the cable core is cut through and a contact connection is established between the conductive core of the cable core and the insulation displacement contact. Several insulation displacement contacts 4 are arranged one behind the other in a first row 12. The side-by-side insulation displacement contacts 4 are separated from one another by clamping webs 31, as shown in FIG. 4. To this first row 12 of insulation displacement contacts 4, a second row 13 of insulation displacement contacts 4 is arranged on the opposite side. As shown in FIG. 1, the first row 12 of insulation displacement contacts 4 is arranged on the upper side 14 and the second row 13 of insulation displacement contacts 4 on the underside 15 of the terminal strip 1.

Jeder Schneid-Klemm-Kontakt 4 der ersten Reihe 12 ist mit einem Schneid-Klemm-Kontakt 4 der zweiten Reihe 13 über ein Verbindungselement 3 verbunden, wodurch auch die an diesen Schneid-Klemm-Kontakten 4 angeschlossenen Kabeladern miteinander verbunden sind.Each insulation displacement contact 4 of the first row 12 is connected to an insulation displacement contact 4 of the second row 13 via a connecting element 3, whereby the cable wires connected to these insulation displacement contacts 4 are also connected to one another.

In dem zweiten Ausführungsbeispiel, welches in Fig. 2 dargestellt ist, ist das Verbindungselement 3 zweitei­lig ausgebildet. Das Verbindungselement 3 besitzt hier zwei aneinanderstoßende Kontaktfedern 6, 7, die eine Trennstelle 8 bilden. Die Anschlußleiste 1 wird somit als Trennleiste 2 ausgebildet. Die Kontaktfeder 7 des Verbindungselementes 3 ist mit dem Schneid-Klemm-Kon­takt 4 der zweiten Reihe verbunden, wobei das Kontakt­ende 32 der Kontaktfeder 7 in einen Schlitz 9 der An­schlußleiste 1 eingesteckt ist und somit unbeweglich gehalten wird. Die Kontaktfeder 6 ist mit dem Schneid-­Klemm-Kontakt 4 der ersten Reihe 12 als einteiliger U-förmiger Trennkontakt 45 ausgebildet, wobei die Kon­taktfeder 6 federnd an der Kontaktfeder 7 anliegt und eine Trennstelle 8 bildet. Fluchtend zu dieser Trenn­stelle 8 ist eine Öffnung 33 in der Anschlußleiste 1 ausgebildet, durch die ein nicht dargestellter Stecker zum Prüfen oder Trennen zwischen die Kontaktfedern 6,7 einsteckbar ist.In the second embodiment, which is shown in Fig. 2, the connecting element 3 is formed in two parts. The connecting element 3 here has two abutting contact springs 6, 7, which form a separation point 8. The terminal block 1 is thus designed as a partition bar 2. The contact spring 7 of the connecting element 3 is connected to the insulation displacement contact 4 of the second row, the contact end 32 of the contact spring 7 being inserted into a slot 9 in the terminal strip 1 and thus being held immovably. The contact spring 6 is formed with the insulation displacement contact 4 of the first row 12 as a one-piece U-shaped isolating contact 45, the contact spring 6 resiliently abutting the contact spring 7 and forming a disconnection point 8. Aligned with this separation point 8, an opening 33 is formed in the terminal block 1, through which an unillustrated plug can be inserted between the contact springs 6, 7 for testing or disconnection.

In der dritten Ausführungsform ist der Schneid-Klemm-­Kontakt 4 der zweiten Reihe 13 zur Vorderseite 16 der Anschlußleiste 1 um 90° abgebogen, so daß das Beschal­ten der Kabeladern von der Vorderseite 16 möglich ist. Eine derartige Anschlußleiste 1 wird insbesondere dort eingesetzt, wo eine Befestigung der Anschlußleiste 1 auf einer ebenen Unterlage erfolgt bzw. wo die Unter­seite 15 der Anschlußleiste 1 nicht zugänglich ist.In the third embodiment, the insulation displacement contact 4 of the second row 13 is bent to the front 16 of the terminal block 1 by 90 °, so that the wiring of the cable wires from the front 16 is possible. Such a connector 1 is used in particular where the connector 1 is attached to a flat surface or where the underside 15 of the connector 1 is not accessible.

Bei den Anschlußleisten 1 aller drei Ausführungsbei­spiele ist seitlich an einer Gehäuseseite 34 eine Auf­nahmekammer 35 für das Überspannungsableitermagazin 10 ausgebildet. Diese Aufnahmekammer 35 ist mit einer parallel zu der ersten Reihe 12 von Schneid-Klemm-Kon­takten 4 verlaufenden Aufnahmenut 27 versehen, in die das Überspannungsableitermagazin 10 eingesteckt ist.In the connection strips 1 of all three exemplary embodiments, a receiving chamber 35 for the surge arrester magazine 10 is formed on the side of a housing 34. This receiving chamber 35 is provided with a receiving groove 27, which runs parallel to the first row 12 of insulation displacement contacts 4 and into which the surge arrester magazine 10 is inserted.

Das Überspannungsableitermagazin 10 weist hierzu zwei über die stirnseitigen Enden herausstehenden Ansätze 36 auf. Die untere Seite 37 des Überspannungsableiterma­gazins 10 liegt auf dem Gehäuseboden 38 der Aufnahme­kammern 35 auf.For this purpose, the surge arrester magazine 10 has two projections 36 which protrude from the front ends. The lower side 37 of the surge arrester magazine 10 lies on the housing bottom 38 of the receiving chambers 35.

Das Überspannungsableitermagazin 10 beinhaltet mehrere Überspannungsableiter 20, die in zwei parallelen Reihen angeordnet sind. Jeder Überspannungsableiter 20 ist einem Schneid-Klemm-Kontaktpaar 4 der Ober- und Unter­seite 14,15 zugeordnet. Die elektrische Verbindung zu den Schneid-Klemm-Kontakten 4 erfolgt über in dem Über­spannungsableitermagazin 10 gelagerten Kontaktzungen 11, die S-förmig ausgebildet sind. Das eine Ende 22 der S-förmigen Kontaktzunge 11 dient als Kontaktfläche 19 für die eine Polseite 24 des Überspannungsableiters 20. Das andere Ende der S-förmigen Kontaktzunge 11 ragt aus dem Gehäuse 18 des Überspannungsableitermagazins 10 heraus und ist zwischen einem Klemmkontakt 5 und dem Verbindungselement 3 eingesteckt. Der Klemmkontakt 5 ist hakenförmig ausgebildet und mit dem Verbindungselement 3 als einteiliges Element ausgebildet. Zwischen der Kon­taktfläche 19 der Kontaktzunge 11 und der ersten Pol­seite 24 des Überspannungsableiters 20 ist eine Klemm­feder 23 angeordnet, die den Überspannungsableiter 20 mit der zweiten Polseite 25 an ein Erdblech 26, 26a andrückt. Das Erdblech 26, 26a ist als U-förmiger Me­tallbügel ausgebildet und besteht, wie insbesondere in Fig. 4 dargestellt ist, aus zwei Teilblechen, die von der Stirnseite her auf das Überspannungsableitermagazin 10 aufgeschoben sind. An den Stirnseiten des Erdbleches 26, 26a sind Blechlappen 39 abgebogen, die mit einem nicht dargestellten Erdanschluß verbunden sind. Die Seitenwände 44 des Erdbleches 26,26a sind abgebogen, wodurch das Erdblech 26,26a am Gehäuse 18 des Überspan­nungsableitermagazins 10 festgehalten ist. Im Überspan­ nungsfall wird die Überspannung, die über die Kontakt­zunge 11 durch den Überspannungsableiter 20 fließt, über das Erdblech 26, 26a und den Erdanschluß abgeleitet.The surge arrester magazine 10 contains a plurality of surge arresters 20, which are arranged in two parallel rows. Each surge arrester 20 is assigned to a pair of insulation displacement contacts 4 on the top and bottom sides 14, 15. The electrical connection to the insulation displacement contacts 4 takes place via contact tongues 11, which are mounted in the surge arrester magazine 10 and are S-shaped. One end 22 of the S-shaped contact tongue 11 serves as a contact surface 19 for one pole side 24 of the surge arrester 20. The other end of the S-shaped contact tongue 11 protrudes from the housing 18 of the surge arrester magazine 10 and is between a clamping contact 5 and the connecting element 3 inserted. The clamping contact 5 is hook-shaped and formed with the connecting element 3 as a one-piece element. Between the contact surface 19 of the contact tongue 11 and the first pole side 24 of the surge arrester 20, a clamping spring 23 is arranged, which presses the surge arrester 20 with the second pole side 25 against an earth plate 26, 26a. The earth plate 26, 26a is designed as a U-shaped metal bracket and, as is shown in particular in FIG. 4, consists of two partial plates which are pushed onto the surge arrester magazine 10 from the front side. Sheet flaps 39 are bent on the end faces of the earth plate 26, 26a and are connected to an earth connection (not shown). The side walls 44 of the earth plate 26, 26 a are bent, as a result of which the earth plate 26, 26 a is held on the housing 18 of the surge arrester magazine 10. In the span voltage case, the overvoltage, which flows through the contact tongue 11 through the surge arrester 20, is derived via the earth plate 26, 26a and the earth connection.

Zum Herausziehen des Überspannungsableitermagazins 10 aus der Anschlußleiste 1 sind seitlich Aufnahmeschlitze 40 vorgesehen, in die ein insbesonders in den Figuren 6 und 7 dargestellter Hebel 41 aufgenommen ist. Dieser Hebel 41 besitzt einen Haken 43, der unter das Überspan­nungsableitermagazin 10 gesteckt ist. Durch Drehen des Hebels 41 um einen Drehpunkt 42 kann somit das Überspan­nungsableitermagazin 10 nach oben ausgeklinkt werden. Die Kontaktverbindung zwischen den Klemmkontakten 5 und den Kontaktzungen 11 wird dadurch gelöst.To pull out the surge arrester magazine 10 from the terminal block 1, there are laterally receiving slots 40 into which a lever 41, which is shown in particular in FIGS. 6 and 7, is received. This lever 41 has a hook 43 which is inserted under the surge arrester magazine 10. By rotating the lever 41 about a pivot point 42, the surge arrester magazine 10 can thus be released upwards. The contact connection between the clamping contacts 5 and the contact tongues 11 is thereby released.

Die Anschlußleiste 1 ist insbesondere in einem nicht dargestellten Endverzweiger oder in einem Endverschluß einbaubar. Die Anschlußleiste 1 wird durch Schrauben, die in den seitlichen Schlitzen 47 der Anschlußleiste 1 aufgenommen sind, an einem Gestellrahmen oder auf einer Montageplatte befestigt. Innerhalb eines Endverzweigers können bis zu zwanzig Anschlußleisten 1 angeordnet werden.The terminal block 1 can in particular be installed in a terminal block (not shown) or in an end closure. The terminal block 1 is fastened to a frame or on a mounting plate by screws which are received in the lateral slots 47 of the terminal block 1. Up to twenty connection strips 1 can be arranged within a terminal block.
