Description

Die Erfindung betrifft eine Vorrichtung zum Lösen und Herausziehen eines in einen Block eingegossenen, an den Enden mit Kontaktklemmen versehenen Mehrleiterkabels aus einem Gehäuse.The invention relates to a device for releasing and withdrawing a multi-conductor cable cast into a block and provided at the ends with contact terminals from a housing.

Gedruckte-Schaltungs-Einheiten, wie sie in elektrischen Schaltungen, insbesondere für Datenverarbeitungsanlagen verwendet werden, enthalten mit jeweils einer Mehrzahl Schaltungskarten bestückte Schaltungsplatten, sogenannte Boards, und eine solche Platteneinheit besteht üblicherweise jeweils aus einer Gedruckten-Schaltungs-Platte, einer daran befindlichen Verstärkungsschicht, einer auf dieser befestigten Kartenführung und den Schaltungskarten, die zur Herstellung der erforderlichen elektrischen Kontakte mit der Platte in der Kartenführung montiert sind. Auf der entgegengesetzten Seite der Platte befinden sich die zugehörigen Kontaktstifte und -schienen für die Signalleitungen und Nullspannungsleiter.Printed circuit units, such as those used in electrical circuits, in particular for data processing systems, contain circuit boards, known as boards, each equipped with a plurality of circuit cards, and such a plate unit usually consists of a printed circuit board, a reinforcing layer thereon, one attached to this card guide and the circuit cards which are mounted in the card guide for making the necessary electrical contacts with the plate. The associated contact pins and rails for the signal lines and zero voltage conductors are located on the opposite side of the plate.

Um auf der Kontaktstiftseite der Platten diejenigen Kontaktanschlüsse, die nicht mittels Gedruckte-Schaltungs-Leiter verbunden werden können, herzustellen, sowie um Änderungen und Verbesserungen der Schaltungsverbindungen, auch im Feld, zu ermöglichen, verwendet man häufig Dreileiterkabel, bestehend aus einem Signalleiter und zwei Null-Leitern, die gemeinsam in dielektrischem Material eingekapselt sind, um die erforderliche Impedanz zu gewährleisten. Die Anschlüsse dieser drei Leiterkabel sind als Kontaktklemmen ausgebildet, und zwar ist je eine Klemme für die Signalspannungen und für die Null-Leiter vorgesehen. Dabei sind die einzelnen Leiter mit den Klemmen verbunden, und diese Anordnung ist lösbar in einem gemeinsamen Kunststoffgehäuse geführt, welches das Aufsetzen der Kontaktstifte und -schienen der Schaltungs-platte erleichtert.In order to make those contact connections on the contact pin side of the plates that cannot be connected by means of printed circuit conductors, and to enable changes and improvements to the circuit connections, also in the field, three-conductor cables consisting of a signal conductor and two zero are often used -Leads that are encapsulated together in dielectric material to ensure the required impedance. The connections of these three conductor cables are designed as contact terminals, namely one terminal each for the signal voltages and for the neutral conductors. The individual conductors are connected to the terminals, and this arrangement is detachably guided in a common plastic housing, which makes it easier to put on the contact pins and rails of the circuit board.

Ist an den Kontaktstiften oder den Kontaktklemmen eine Beschädigung aufgetreten, oder sollen die Schaltungsverbindungen geändert werden, so ist es erforderlich, die Verbindungen des Dreileiterkabels am Gehäuse zu lösen, wobei eine gewisse elastische Verriegelungskraft zwischen den Klemmenansätzen und der Gehäusekante zu überwinden ist. Hierzu verwendet man normalerweise eine spezielle Kabelzange, jedoch werden dabei unkontrollierbare Druckkräfte auf die Signal- und die Null-Leiter wirksam, mit der Folge, daß die Leiter unzulässig zusammengedrückt werden und Schäden an dem Kabel entstehen können, insbesondere ein Leiter unterbrochen wird oder zwei Leiter kurzgeschlossen werden.If damage has occurred to the contact pins or the contact terminals, or if the circuit connections are to be changed, it is necessary to loosen the connections of the three-wire cable on the housing, whereby a certain elastic locking force must be overcome between the terminal approaches and the housing edge. For this one usually uses a special K portable tongs, but it uncontrollable compressive forces on the signal and the neutral conductor to take effect, with the result that the conductors are compressed prohibited and may result in damage to the cable, in particular a conductor is interrupted or two Conductor short-circuited.

Der Erfindung liegt die Aufgabe zugrunde, ein Werkzeug zu schaffen, mit dem die Leiter, z.B. eine Dreileiteranordnung, aus dem Gehäuse gelöst werden können, ohne daß die Gefahr einer Beschädigung der Leiter besteht. Diese Aufgabe ist mit der Vorrichtung gemäß Patentanspruch 1 gelöst worden.The invention has for its object to provide a tool with which the conductors, e.g. a three-wire arrangement, can be released from the housing without the risk of damaging the conductor. This object has been achieved with the device according to claim 1.

Die erfindungsgemäße Vorrichtung erleichtert das Lösen und Herausziehen des Mehrleiterkabels aus dem Gehäuse, indem insbesondere das Herausziehen schneller durchgeführt werden kann und dabei ausgeschlossen ist, daß ein Schaden an den einzelnen Leitern auftreten kann. Um ein Mehrleiterkabel vom Gehäuse abzuziehen, wird zunächst das Gehäuse von der Schaltungsplatte gelöst und sodann die erfindungsgemäß vorgesehene Federzunge zwischen das Gehäuse und die Verkapselung der Leiter gesteckt, bis der daran befindliche Haken die Vorderkante des Kabelblocks hintergreift. Währenddessen gleitet der genutete Ansatz des Werkzeugs an dem Führungsteil des Gehäuses und sorgt für die Ausrichtung des Werkzeugs zum Kabel. Durch Betätigung der Handhabe gegen die Kraft der Feder wird dann auf einfache Weise das Kabel herausgezogen.The device according to the invention facilitates the detaching and pulling out of the multi-conductor cable from the housing, in particular in that the pulling out can be carried out more quickly and it is thereby excluded that damage to the individual conductors can occur. In order to pull a multi-conductor cable from the housing, the housing is first detached from the circuit board and then the spring tongue provided according to the invention is inserted between the housing and the encapsulation of the conductors until the hook located there engages behind the front edge of the cable block. In the meantime, the grooved attachment of the tool slides on the guide part of the housing and ensures that the tool is aligned with the cable. By actuating the handle against the force of the spring, the cable is then simply pulled out.

Gemäß Fig. 1 ist ein Dreileiterkabel 10 in ein Kunststoffgehäuse 11 eingesetzt. Das Dreileiterkabel 10 besteht aus einem zentralen Signalspannungsleiter 12 und zwei äußeren Null-Leitern 13. Der Signalspannungsleiter 12 kreuzt einen der Null-Leiter 13 und ist mit einer gabelförmigen Kontaktklemme 14, vorzugsweise durch sog. Crimpen, verbunden, während die beiden Null-Leiter 13 in gleicher Weise mit einer Kontaktklemme 15 verbunden sind. Die Kontaktklemmen 14 und 15 liegen in einer Ebene. Diejenigen Bereiche, in denen der Signalspannungsleiter 12 einen der Null-Leiter 13 kreuzt, sowie in denen sich die Verbindung der Leiter mit den Kontaktklemmen 14 befindet, befinden sich in einem Kabelblock 16 aus dielektrischem Werkstoff, der vorzugsweise als dielektrischer Film ausgestaltet ist.1, a three-wire cable 10 is inserted into a plastic housing 11. The three-wire cable 10 consists of a central signal voltage conductor 12 and two outer neutral conductors 13. The signal voltage conductor 12 crosses one of the neutral conductors 13 and is connected to a fork-shaped contact terminal 14, preferably by so-called crimping, while the two neutral conductors 13 are connected in the same way to a contact terminal 15. The contact terminals 14 and 15 lie in one plane. The areas in which the signal voltage conductor 12 crosses one of the neutral conductors 13, and in which the connection of the conductors to the contact terminals 14 is located, are located in a cable block 16 made of dielectric material, which is preferably designed as a dielectric film.

Die Enden der Kontaktklemmen 14 und 15 sind mit widerhakenförmigen Ansätzen versehen, die Verriegelungsabsätze 18 am Gehäuse 11 hintergreifen, wodurch die Kontaktklemmen 14, 15 und somit das Dreileiterkabel 10 mit dem Kabelblock 16 lösbar im Gehäuse 11 befestigt ist. Die Öffnung zwischen den Kabelteilen der Kontaktklemme 14 ist mit einem Durchbruch 19 im Gehäuse 11 ausgerichtet, der ein Aufstecken auf einen entsprechenden Stift auf der Gedruckten-Schaltungs-Platte ermöglicht. Das Gehäuse weist weiterhin einen Schlitz 20 auf, der mit der öffnung zwischen den beiden Kabelteilen der Kontaktklemme 15 ausgerichtet ist und das Aufstecken auf die Null-Leiterschiene der Gedruckten-Schaltungs-Platte ermöglicht. Ein Führungsteil 21 von T-förmigem Querschnitt am Gehäuse 11 dient zur Ausrichtung und Führung des nachfolgend beschriebenen Werkzeugs zum Lösen und Herausziehen des Dreileiterkabels.The ends of the contact terminals 14 and 15 are provided with barb-shaped lugs, which engage locking shoulders 18 on the housing 11, as a result of which the contact terminals 14, 15 and thus the three-wire cable 10 with the cable block 16 are detachably fastened in the housing 11. The opening between the cable parts of the contact terminal 14 is aligned with an opening 19 in the housing 11, which enables it to be plugged onto a corresponding pin on the printed circuit board. The housing also has a slot 20 which is aligned with the opening between the two cable parts of the contact terminal 15 and enables the plugging onto the zero conductor rail of the printed circuit board. A guide part 21 of T-shaped cross-section on the housing 11 serves to align and guide the tool described below for loosening and pulling out the three-wire cable.

Das in den Fign. 3 und 4 dargestellte Werkzeug besteht aus einem zylindrischen Gehäusemantel, in dem ein Kolben 23 längsverschiebbar geführt ist. In einer radialen Bohrung 26 des Kolbens 23 befindet sich eine Griffstange 24, die durch Schlitze 25 im Gehäusemantel 22 geführt ist und somit eine begrenzte Längsbewegung des Kolbens 23 im Gehäusemantel 22 ermöglicht. Eine Druckfeder 27 ist zwischen einem Druckstück 28 an der Rückseite des Kolbens 23 und einem Schaft 29 eines Knopfs 30 angeordnet. Der Knopf 30 ist mittels eines Stiftes 31 am Gehäusemantel 22 befestigt.The in Figs. 3 and 4 shown tool consists of a cylindrical housing shell in which a piston 23 is guided in a longitudinally displaceable manner. In a radial bore 26 of the piston 23 there is a handle bar 24 which is guided through slots 25 in the housing jacket 22 and thus enables a limited longitudinal movement of the piston 23 in the housing jacket 22. A compression spring 27 is arranged between a pressure piece 28 on the rear of the piston 23 and a shaft 29 of a button 30. The button 30 is attached to the housing jacket 22 by means of a pin 31.

Am vorderen Ende des Kolbens 23 befindet sich eine axial herausragende Federzunge 32, an deren Ende ein Haken 33 angeformt ist. Die Druckfeder 27 ist so auf den Kolben 23 wirksam, daß dessen Absatz 34 an einer entsprechenden Anschlagfläche. im Gehäusemantel 22 anliegt. Diese Position, in der sich der Haken 33 der Federzunge 32 benachbart zu einem genuteten Ansatz 35 des Gehäusemantels 22 befindet, ist in Fig. 4 dargestellt.At the front end of the piston 23 there is an axially protruding spring tongue 32, at the end of which a hook 33 is formed. The compression spring 27 is effective on the piston 23 so that its shoulder 34 on a corresponding stop surface. rests in the housing jacket 22. This position in which the hook 33 of the spring tongue 32 is adjacent to one grooved approach 35 of the housing shell 22 is shown in Fig. 4.

Zum Lösen und Herausziehen des Dreileiterkabels jO aus dem Kunststoffgehäuse 11 wird das Werkzeug in der Position des Kolbens gemäß Fig. 4, also mit entspannter Druckfeder 27, so in das Gehäuse eingeführt, daß die Federzunge 32 zwischen dem Gehäuse 11 und dem Kabelblock 16 hindurch so weit nach vorne gelangt, daß der Haken 33 die vordere Kante des Kabelblocks 16 hintergreift. Gleichzeitig dient das Zusammenwirken des Führungsteils 21 mit dem genuteten Ansatz 35 zur Sicherung der Relativlage zwischen Werkzeug und Gehäuse 11 (Fig. 2). Sobald der Haken 33 der Federzunge 32 die Vorderkante 36 des Kabelblocks 16 erfasst hat, wird das Werkzeug an der Griffstange 24 entgegen der Kraft der Druckfeder 27 zurückgezogen, wodurch die Ansätze 17 der Kontaktklemmen 14 und 15 in Bezug auf die Verriegelung zu Absätze 18 des Gehäuses 11 entriegelt werden und das Herausziehen des Dreileiterkabels 10 aus dem Gehäuse 11 ermöglichen. Nach dem Herausziehen wird die Griffstange 24 freigegeben, und der Kolben 23 kehrt unter der Kraft der Druckfeder 27 in seine vordere Ausgangslage zurück.To release and pull out the three-wire cable OK from the plastic housing 11, the tool is inserted into the housing in the position of the piston according to FIG. 4, that is to say with the compression spring 27 relaxed, so that the spring tongue 32 between the housing 11 and the cable block 16 passes through it reaches far forward that the hook 33 engages behind the front edge of the cable block 16. At the same time, the interaction of the guide part 21 with the grooved shoulder 35 serves to secure the relative position between the tool and the housing 11 (FIG. 2). As soon as the hook 33 of the spring tongue 32 has gripped the front edge 36 of the cable block 16, the tool on the handle bar 24 is withdrawn against the force of the compression spring 27, as a result of which the lugs 17 of the contact terminals 14 and 15 relate to the locking to paragraphs 18 of the housing 11 are unlocked and allow the three-wire cable 10 to be pulled out of the housing 11. After pulling out, the handle bar 24 is released and the piston 23 returns to its initial position under the force of the compression spring 27.

Im dargestellten Ausführungsbeispiel befindet sich im Gehäuse 11 ein Dreileiterkabel. Nimmt, abweichend von diesem Beispiel, das Gehäuse 11 eine Mehrzahl von Mehrleiterkabeln auf, so wird mit dem beschriebenen Werkzeug jeweils ein Mehrleiterkabel nach dem anderen in der beschriebenen Weise herausgezogen.In the illustrated embodiment, a three-wire cable is located in the housing 11. If, contrary to this example, the housing 11 accommodates a plurality of multi-conductor cables, one multi-conductor cable after the other is pulled out in the manner described with the tool described.
