Abstract

In order to branch off from a continuous electric line (6) at least one other limited or continuous electric line (7), a potential distributor has an insulating housing that consists of an inner part (1) and of an outer part that can be set on the inner part (1) like a hat. A contact piece (3) housed in the outer part (2) has at least two pairs of U-shaped insulation displacement clips (4, 5) that stand on the contact piece (3). Both insulation displacement clips of each pair provided for one electric line stand exactly opposite each other. When the housing is closed, the electric lines (6, 7) are clamped in the insulation displacement clips and the tension on the electric lines (6, 7) is relieved on both sides of each insulation displacement clip.

Elektrischer Potentialverteiler in SchneidklemmtechnikElectrical potential distributor using insulation displacement technology
Die Erfindung betrifft einen elektrischen Potentialverteiler in Schneidklemmtechnik.The invention relates to an electrical potential distributor using insulation displacement technology.
Im Innenraum (Trockenbereich) von Kraftfahrzeugen ist es häu¬ fig wünschenswert bzw. erforderlich, bei der elektrischen Verdrahtung (Kabelbaum) von einer durchgehenden Leitung einen Anschluß abzuzweigen. Die bisherige Lösung setzt an den Lei¬ tungsenden an. Dazu werden diese Leitungsenden jeweils mit einem Crimpkontakt versehen, welche dann auf ein gemeinsames kammerartiges Mehrfachmesser aufgesteckt werden, so daß die Leitungen untereinander elektrisch verbunden sind. Aus derIn the interior (dry area) of motor vehicles, it is often desirable or necessary to branch off a connection in the electrical wiring (wiring harness) from a continuous line. The previous solution starts at the line ends. For this purpose, these cable ends are each provided with a crimp contact, which are then plugged onto a common chamber-like multiple knife, so that the cables are electrically connected to one another. From the
DE 88 08 408 UI ist ein derartiger Kfz-Potentialverteiler be¬ kannt, der durch ein Kunststoffgehäuse gebildet ist, in dem eine Kontaktplatte angeordnet ist, die Lagerelemente für eine Anzahl von Crimpkontakten aufweist. Es ist damit jedoch nicht möglich, eine durchgehende Leitung zu haben. Diese bekannte Art der Verzweigung führt vielmehr dazu, daß immer mehrere Leitungsenden zusammengeführt werden müssen, wodurch gro߬ bauende Einheiten entstehen.Such a motor vehicle potential distributor is known from DE 88 08 408 UI, which is formed by a plastic housing in which a contact plate is arranged, which has bearing elements for a number of crimp contacts. However, it is not possible to have a continuous line. Rather, this known type of branching means that a plurality of line ends always have to be brought together, as a result of which large units are created.
Aus der DE-OS 34 22 607 ist ein Anschluß für ein mehradrigesFrom DE-OS 34 22 607 is a connection for a multi-core
Flachkabel, insbesondere ein Fernmeldekabel, in Gestalt eines aus einem Unterteil und einer korrespondierenden Abdeckung bestehenden Anschlußblocks bekannt, wobei das Flachkabel zwi¬ schen Unterteil und Abdeckung des Anschlußblocks eingefügt wird. Im Unterteil sind Schneidklemm-Kontakte angeordnet, die im Einbauzustand die Isolierung des Flachkabels durchdringen und die jeweilige Ader des Kabels mit Klemmsitz übergreifen. Der genannten Offenlegungsschrift geht es darum, den Anschluß bzw. Abgriff an Fernmelde-Flachkabeln so auszugestalten, daß auch wenn zur Vermeidung von gegenseitigen störenden Beein¬ flussungen der Signalleiter Erdungsleiter zwischen den Si¬ gnalleitern vorgesehen werden, die volle Anzahl der Bestand- teil des Kabels bildenden Leiter als Signalleiter zur Verfü¬ gung steht . Zu diesem Zweck werden Schaltungsvarianten vorge¬ schlagen, von denen einige dem Abzweigen einer Leitung von einer anderen durchgehenden Leitung ähneln. Prinzipiell wer- den jedoch bei dem bekannten Anschluß durchgehende Erdungs- leiter mit dazwischen angeordneten Signalleiter-Teilstücken durch gegeneinander versetzt angeordnete Einzel-Schneidklem¬ men, die in einer Platte zusammengefaßt sind, verbunden. Die gesamte Innenseite der genau auf das Unterteil passenden Ab- deckung ist entsprechend der Oberflächenstruktur des Kabels gewählt, um dieses aufnehmen zu können. Eine Zugentlastung der Schneidklemm-Kontakte ist damit jedoch nicht verbunden.Flat cable, in particular a telecommunication cable, in the form of a connection block consisting of a lower part and a corresponding cover is known, the flat cable being inserted between the lower part and cover of the connection block. In the lower part there are insulation displacement contacts which penetrate the insulation of the flat cable in the installed state and overlap the respective core of the cable with a clamp fit. The cited publication is concerned with designing the connection or tapping on flat telecommunication cables in such a way that even if the signal conductors are provided with ground conductors between the signal conductors to avoid mutual interference, the full number of existing part of the cable-forming conductor is available as a signal conductor. For this purpose, circuit variants are proposed, some of which resemble the branching of a line from another continuous line. In principle, however, in the known connection, continuous ground conductors are connected to signal conductor sections arranged between them by means of individual insulation displacement terminals which are offset from one another and are combined in a plate. The entire inside of the cover that fits exactly on the lower part is selected in accordance with the surface structure of the cable in order to be able to accommodate it. However, this does not involve strain relief of the insulation displacement contacts.
Aus der DE-OS 33 33 973 ist im übrigen eine Kontaktklemme für Leiterplatten bekannt geworden, die aus zwei scharnierartig miteinander verbundenen Gehäuseteilen und in einem dieser Teile enthaltenen Kontaktmessern besteht. Beim Festklemmen der Adern einer Leitung zwischen diesen Gehäuseteilen und de¬ ren Verrasten in geschlossener Schwenkstellung durchdringen die Schneiden der Kontaktmesser die Isolation der Leitungs- adern und bewirken über zum Kontaktmesser gehörende Lötfahnen den galvanischen Anschluß der betreffenden Leiterbündel mit der unterhalb der Kontaktklemme befindlichen Leiterplatte.From DE-OS 33 33 973 a contact terminal for printed circuit boards has also become known, which consists of two hinge-like interconnected housing parts and contact blades contained in one of these parts. When clamping the wires of a line between these housing parts and locking them in the closed pivot position, the cutting edges of the contact knives penetrate the insulation of the line wires and, via soldering tabs belonging to the contact knife, effect the galvanic connection of the relevant conductor bundle to the circuit board located below the contact terminal.
Der Erfindung liegt die Aufgabe zugrunde, einen verbesserten Potentialverteiler zu schaffen, bei dem eine Leitung von ei¬ ner anderen, insbesondere durchgehenden Leitung abzweigbar ist .The invention is based on the object of providing an improved potential distributor in which a line can be branched off from another, in particular continuous line.

Im folgenden wird die Erfindung anhand eines Ausführungsbei- spiels und den Figuren der Zeichnung näher erläutert. Es zeig :The invention is explained in more detail below on the basis of an exemplary embodiment and the figures of the drawing. It shows:

Figur 8 eine weitere Ausführungsform eines Kontaktteils mit hochstehenden Schneidklemmen-Paaren.Figure 8 shows a further embodiment of a contact part with upstanding pairs of insulation displacement terminals.
Der in Figur 1 dargestellte Potentialverteiler besteht im we¬ sentlichen einerseits aus Schneidklemmen-Paaren 4 und 5, also einem Paar je Leitung. Bei der Ausführung gemäß Figur 1 fin- det ein U-förmiges Kontaktteil 3 Verwendung, wie es weiter unten näher beschrieben wird. Des weiteren besteht der Poten¬ tialverteiler aus einem zweiteiligen Isolierstoffgehäuse, dem Innenteil 1 und dem Außenteil 2. Das Kontaktteil 3 befindet sich durch seitlich und/oder an der Unterseite angebrachte Nasen 17 vor dem Herausfallen geschützt im Außenteil 2. Das Innenteil 1 ist mit dem Außenteil durch ein Filmgelenk 8 ver¬ bunden. Abweichend von der dargestellten Ausführungsform kön¬ nen das Innen- und das Außenteil 1 und 2 jedoch auch als ge¬ trennte Teile vorgesehen werden. Alternativ können die beiden Teile mit einem oder mehreren kurzen Stegen verbunden sein, die dann während der Konfektionierung aufgebrochen werden. Weitere unschwer ausführbare Alternativen sind dadurch gege¬ ben, daß Innen- und Außenteil 1 und 2 mittels eines Dreh- Schiebe-Gelenkε oder mittels einer Schiebe-Schiebe-Verbindung verbunden sind.The potential distributor shown in FIG. 1 essentially consists on the one hand of pairs of insulation displacement terminals 4 and 5, that is to say one pair per line. In the embodiment according to FIG. 1, a U-shaped contact part 3 is used, as will be described in more detail below. Furthermore, the potential distributor consists of a two-part insulating material housing, the inner part 1 and the outer part 2. The contact part 3 is protected from falling out in the outer part 2 by lugs 17 mounted on the side and / or on the underside. The inner part 1 is connected to the The outer part is connected by a film joint 8. In a departure from the embodiment shown, the inner and outer parts 1 and 2 can also be provided as separate parts. Alternatively, the two parts can be connected to one or more short webs, which are then broken open during assembly. Further alternatives which are not difficult to implement are given in that the inner and outer parts 1 and 2 are connected by means of a rotary-slide joint or by means of a slide-slide connection.
Im Auslieferungszustand gemäß Figur 1 ist das Isolierstoffge¬ häuse völlig offen. Die Oberseite des Innenteils 1 ist leicht zugänglich. Die Leitungen 6 und 7 werden zur Konfektionierung zunächst in vorzugsweise im inneren Bereich des Isolierstoff¬ gehäuses angeordnete Vorfixierzonen 9 (vgl. Figur 4) einge¬ bracht. Zur Leitungsvorfixierung ist es vorteilhaft, am In¬ nenteil 1 angeordnete Vorfixierungskonturen 13 vorzusehen. Durch diese werden zur Erleichterung der Handhabung die Lei- tungen 6, 7 nach dem Einlegen in das Innenteil 1 des Gehäuses gehalten, so daß sie bei der weiteren Verarbeitung ihre Lage nicht mehr verändern. Im Verarbeitungsablauf anschließend wird das Außenteil 2 auf das Innenteil 1 aufgeschwenkt und manuell, durch Drücken, in Vorraststellung gebracht. Im einzelnen besteht eine vorteil- hafte Ausgestaltung darin, daß am Innenteil 1 und am Außen¬ teil 2 Rastmittel 18, 19, 20 vorgesehen sind, durch die diese Gehäuseteile beim gegenseitigen Verschieben in einer Vorrast- Position und in der Endposition verrastbar sind, wobei in der Vorrastposition die durch die Vorfixierungskonturen 13 gege- bene Leitungsvorfixierung durch die die Leitungen 6 und 7 be¬ rührenden Anschnittkanten 14 bzw. 15 der Schneidklemmen 4 bzw. 5 verstärkt ist. Um die Leitungen nicht mehr zu bewegen, wird das Innenteil 1 beim Aufschwenken ruhig gehalten. In der Vorraststellung hinterschneiden die Rasthaken 18 des Innen- teils 1 an den oberen Vorsprüngen 20. Die Fixierung der Lei¬ tungen 6, 7 wird in diesem, in Figur 2 dargestellten Zustand durch die Anschnittkanten 14 und 15 der Schneidklemmen 4 bzw. 5 also zwar verstärkt, die Leitungen 6, 7 sind jedoch noch nicht kontaktiert.In the delivery state according to FIG. 1, the insulating material housing is completely open. The top of the inner part 1 is easily accessible. The cables 6 and 7 are first inserted into prefixing zones 9 (see FIG. 4), which are preferably arranged in the inner region of the insulating material housing. For cable pre-fixing, it is advantageous to provide pre-fixing contours 13 arranged on the inner part 1. To facilitate handling, the lines 6, 7 are held by these after insertion into the inner part 1 of the housing, so that they no longer change their position during further processing. In the processing sequence, the outer part 2 is then pivoted onto the inner part 1 and manually brought into the pre-locking position by pressing. In particular, an advantageous embodiment consists in that latching means 18, 19, 20 are provided on the inner part 1 and on the outer part 2, by means of which these housing parts can be latched in a pre-latching position and in the end position when they are mutually displaced the pre-locking position, the pre-fixing given by the pre-fixing contours 13 is reinforced by the cut edges 14 and 15 of the insulation displacement contacts 4 and 5, respectively, which touch the lines 6 and 7. In order not to move the lines anymore, the inner part 1 is kept still when it is swung open. In the pre-latching position, the latching hooks 18 of the inner part 1 undercut on the upper projections 20. The fixing of the lines 6, 7 in this state, shown in FIG reinforced, but the lines 6, 7 are not yet contacted.
In der in Figur 3 dargestellten Endposition hinterschnappen die Rasthaken 19 des Innenteils 1 an nicht dargestellten un¬ teren Vorsprüngen des Außenteils 2. Es können weitere Rast- ittel am Außenteil 2 und am angedeuteten Vorsprung 21 des Innenteils 1 vorgesehen werden. Das Gehäuse ist dadurch kräf¬ tig verschlossen und kann nur noch gewaltsam geöffnet werden.In the end position shown in FIG. 3, the latching hooks 19 of the inner part 1 snap onto lower projections of the outer part 2, not shown. Further latching means can be provided on the outer part 2 and on the indicated projection 21 of the inner part 1. The housing is thereby closed tightly and can only be opened by force.
Zur beidseitigen Zugentlastung sind vorteilhaft Konturen am Isolierstoffgehäuse ausgebildet, die zwischen der Eintritts- bzw. Endzone 12 der Leitungen 6, 7 im Außenbereich des Iso- lierstoffgehäuses und der weiter innenliegenden Kontaktie- rungszone 11 angeordnet sind. Diese Zugentlastungszone 10 ist in Figur 4 angedeutet. Dies gewährleistet, daß durch die je¬ weilige Leitung eingebrachte Zugkräfte im Gehäuse abgefangen werden, bevor diese sich an der Kontaktierungsstelle, also an den Schneidklemmen 4, 5 auswirken können. Da die Zugentla¬ stung beidseitig am Gehäuse vorgesehen ist, ist es hierbei auch unwichtig, von welcher Seite der Zug kommt. Auch bei Zugkraft an beiden Leitungsenden ist die Zugentlastung voll wirksam. Die Leitungen 6, 7 können insbesondere, wie darge¬ stellt, bei geschlossenem Potentialverteiler jeweils je etwa zur Hälfte von einer Kontur 16 am Innenteil 1 und am Außen¬ teil 2 umfaßt und klemmend gehalten sein. Vorteilhaft gräbt sich dabei ein Sägezahn-Profil in die Isolation der Leitung 6, 7 ein.For strain relief on both sides, contours are advantageously formed on the insulating housing, which are arranged between the inlet or end zone 12 of the lines 6, 7 in the outer region of the insulating material housing and the contact zone 11 located further inside. This strain relief zone 10 is indicated in FIG. 4. This ensures that tensile forces introduced by the respective line are absorbed in the housing before they can have an effect on the contacting point, that is to say on the insulation displacement terminals 4, 5. Since the strain relief is provided on both sides of the housing, it is here it doesn't matter which side the train comes from. The strain relief is fully effective even with tensile force at both ends of the line. The lines 6, 7 can, in particular, as shown, with a closed potential distributor each encompassed approximately half by a contour 16 on the inner part 1 and on the outer part 2 and held in a clamping manner. A sawtooth profile advantageously digs into the insulation of the line 6, 7.
In Figur 4 ist in Draufsicht auf das Innenteil 1 ein ge¬ schlossener Potentialverteiler für zwei Leitungen darge¬ stellt, mit einer durchgehenden Leitung 6 und einer endenden Leitung 7. Angedeutet sind ferner die Vorfixierungszone 9, die Zugentlastungszone 10, die Kontaktierungszone 11 und die Eintritts- bzw. Endzone 12.FIG. 4 shows a top view of the inner part 1 of a closed potential distributor for two lines, with a continuous line 6 and an ending line 7. Also indicated are the pre-fixing zone 9, the strain relief zone 10, the contacting zone 11 and the entry - or end zone 12.
In den Figuren 5 bis 7 sind zwei parallel zueinander hochste¬ hende Schneidklemmen-Paare 4 und 5 dargestellt, die ein U- fόrmiges Kontaktteil 3 bilden. Die Schneidklemmen-Paare 4 und 5 sind miteinander durch das Trägerband 22 mechanisch und elektrisch verbunden. Die Schneidklemmen 4 und 5 sind vom Trägerband 17 hochgebogen, so daß sich die zwei Schneidklem¬ men eines Paares unversetzt gegenüberstehen und ein U-förmi¬ ges Kontaktteil 3 bilden können.FIGS. 5 to 7 show two pairs of insulation displacement clips 4 and 5 which stand parallel to one another and form a U-shaped contact part 3. The insulation displacement pairs 4 and 5 are mechanically and electrically connected to one another by the carrier tape 22. The insulation displacement terminals 4 and 5 are bent up from the carrier tape 17 so that the two insulation displacement terminals of a pair face each other without offset and can form a U-shaped contact part 3.
Es ist jedoch auch möglich, daß die hochstehenden Schneid¬ klemmen-Paare in einem Winkel zueinander auf dem Kontaktteil 3 angeordnet und die Leitungen mit entsprechenden Winkeln zu¬ einander weggeführt sind. Eine Ausführungsform, bei der die durchgehende Leitung 6 selbst schon mittels zwei hintereinan¬ der angeordneten Schneidklemmen-Paaren kontaktiert ist und bei der drei endende Leitungen in rechtem Winkel weggeführt werden, ist in Figur 8 dargestellt.However, it is also possible for the upstanding pairs of insulation displacement terminals to be arranged at an angle to one another on the contact part 3 and for the lines to be routed away from one another at corresponding angles. An embodiment in which the continuous line 6 is itself contacted by means of two pairs of insulation displacement clamps arranged one behind the other and in which three terminating lines are led away at a right angle is shown in FIG.
Der Potentialverteiler in Schneidklemmtechnik kann demnach von einer durchgehenden oder endenden Leitung in eine andere Leitung abzweigen. Diese kann ebenfalls sowohl als endende Leitung oder als durchgehende Leitung ausgebildet sein. Auch ist durch die Einführung weiterer Schneidklemmen und der Er¬ weiterung des Isolierstoffgehäuses der Abzweig von mehreren Leitungen möglich. The potential distributor in insulation displacement technology can therefore branch off from a continuous or terminating line into another line. This can also be both an ending Line or be formed as a continuous line. The introduction of further insulation displacement terminals and the expansion of the insulating material housing also make it possible to branch off several lines.
