Description

Die Erfindung betrifft eine elektrische Kontaktanordnung nach dem Oberbegriff des Anspruchs 1. Solche Kontaktanordnungen finden vorzugsweise mit einer grossen Anzahl von über die Länge eines mehradrigen Kabels verteilten Anschlussstellen und einer entsprechenden Anzahl von mehrpoligen Anschlusssteckern für die Parallel-Stromversorgung von Verbrauchern, vor allem von Niederstrom- und/oder Niederspannungsverbrauchern wie Lampen und dergl., verbreitet Anwendung.The invention relates to an electrical contact arrangement according to the preamble of claim 1. Such contact arrangements are preferably found with a large number of connection points distributed over the length of a multi-core cable and a corresponding number of multi-pole connection plugs for the parallel power supply of consumers, especially low-current and / or low voltage consumers such as lamps and the like, is widely used.

Eine Kontaktanordnung der vorgenannten Art ist bekannt aus der DE 30 19 060 A1. Dort ist je Anschlussstelle nur eine zwischen zwei nebeneinanderliegenden Adern eines Flachkabels angeordnete Isolierungsausnehmung vorgesehen. An einander diametral gegenüberliegenden Randbereichen einer Isolierungsausnehmung liegen beide Leiter unter Bildung entsprechender Kontaktstellen frei. Jeder Anschlussstecker weist nur einen Steckkontakt auf, der zwei einander im Steckerquerschnitt diametral gegenüberliegende, quer zur Leiterlängsrichtung langgestreckte und voneinander durch einen Isolierkörper getrennte Kontaktelemente umfasst. Durch Drehen des in eine Isolierungsausnehmung eingesetzten Steckers um eine quer zur Leiterlängsrichtung orientierte Mittelachse der Isolierungsausnehmung kann die beiden Kontaktelementen gemeinsame Ebene zwischen einer quer zur Leiterlängsrichtung orientierten Einschaltlage und einer parallel zur Leiterlängsrichtung orientierten Ausschaltlage verstellt werden.A contact arrangement of the aforementioned type is known from DE 30 19 060 A1. There, only one insulation recess is provided per connection point between two adjacent wires of a flat cable. At diametrically opposite edge areas of an insulation recess both conductors are exposed, forming appropriate contact points. Each connector has only one plug contact, which comprises two contact elements diametrically opposite one another in the plug cross section, elongated transversely to the longitudinal direction of the conductor and separated from one another by an insulating body. By rotating the plug inserted into an insulation recess about a central axis of the insulation recess oriented transversely to the longitudinal direction of the conductor, the two contact elements common plane can be adjusted between a switch-on position oriented transversely to the longitudinal direction of the conductor and a switch-off position oriented parallel to the longitudinal direction of the conductor.

Verbesserungsbedürftig ist bei der bekannten Ausführung die Sicherheit der Kontakthaltung, weil der zweipolige Steckkontakt in seiner Einschaltstellung im wesentlichen nur reibungsschlüssig gesichert ist und daher keine zuverlässig gleichbleibenden Kontaktflächen gewährleisten kann. Für manche Anwendungsfälle besteht auch der Wunsch nach erhöhter Spannungsfestigkeit zwischen den Leitern bzw. Kabeladern im Bereich der Anschlussstellen, die bei der bekannten Ausführung wegen des vergleichsweise geringen Abstandes zwischen den Kontaktelementen des Steckkontaktes vor allem in feuchter Umgebung recht begrenzt ist.In the known design, the safety of the contact maintenance is in need of improvement, because the two-pole plug contact is essentially only frictionally secured in its switched-on position and therefore cannot guarantee reliably constant contact surfaces. For some applications there is also a desire for increased dielectric strength between the conductors or cable cores in the area of the connection points, which is quite limited in the known embodiment because of the comparatively small distance between the contact elements of the plug contact, especially in a humid environment.

Aufgabe der Erfindung ist daher die Schaffung einer Kontaktanordnung, die sich gegenüber dem Bekannten durch erhöhte Kontaktsicherheit sowie gegebenenfalls durch erhöhte Spannungsfestigkeit auszeichnet. Die erfindungsgemässe Lösung dieser Aufgabe kennzeichnet sich durch die Merkmale des Anspruchs 1 bzw. des Anspruchs 5.The object of the invention is therefore to create a contact arrangement which differs from the known through increased contact reliability and possibly through increased dielectric strength distinguished. The inventive solution to this problem is characterized by the features of claim 1 and claim 5.

Infolge der erfindungsgemäss vorgesehenen Kontaktierung innerhalb einer Mehrzahl von Isolierungsausnehmungen mit einer entsprechenden Anzahl von Steckkontakten, die somit im allgemeinen je einpolig ausgeführt werden können, ergibt sich eine vorteilhaft einfache Möglichkeit zur formschlüssigen Arretierung der Kontakte in ihrer Anschluss- bzw. Einschaltstellung. Dies gilt nicht nur für jene Ausführungen, die im eingesetzten Zustand des Anschlusssteckers keine Schaltmöglichkeit aufweisen, also nur durch Einsetzen und Ziehen des Steckers schaltbar sind, sondern auch für solche Ausführungen, die durch Drehen oder Verschieben des eingesetzten Steckers zwischen verschiedenen Stellungen schaltbar sind. Gerade hier lässt sich nämlich mit Hilfe von gegeneinander abgegrenzten Isolierungsausnehmungen zur Aufnahme jeweils eines Steckkontaktes in einer Einschaltstellung - oder mehrerer derselben - einerseits und einer Ausschaltstellung andererseits sowie ferner mit Hilfe von Durchlässen innerhalb des Isoliermaterials zwischen diesen Ausnehmungen für das Verschieben des Steckkontaktes eine sichere Formschlussarretierung des Steckkontaktes in seinen verschiedenen Wirkstellungen sowie eine zuverlässige Kontaktgabe bzw. Kontakttrennung erreichen. Weiterhin lassen sich die gegenseitigen Abstände der Kontaktelemente und damit die Kriechstromwege an den verschiedenen Steckkontakten eines Anschlusssteckers ohne grundsätzliche Einschränkung durch die zulässigen Querschnittsabmessungen eines mehrpoligen Steckkontaktes bequem auf vergleichsweise grosse Werte bringen.As a result of the contacting provided according to the invention within a plurality of insulation recesses with a corresponding number of plug contacts, which can thus generally be single-pole, there is an advantageously simple possibility for positive locking of the contacts in their connection or switch-on position. This applies not only to those versions that do not have a switch option when the connector is in the inserted state, i.e. can only be switched by inserting and pulling the connector, but also to those versions that can be switched between different positions by rotating or moving the inserted connector. It is precisely here that with the help of mutually delimited insulation recesses for receiving a plug contact in one switch-on position - or several of them - on the one hand and a switch-off position on the other hand, and furthermore with the help of passages within the insulating material between these recesses for moving the plug contact, a secure positive locking of the Achieve plug contact in its various active positions as well as reliable contact making or contact separation. Furthermore, the mutual spacing of the contact elements and thus the leakage current paths at the various plug contacts of a connector can be avoided Basic restriction by the permissible cross-sectional dimensions of a multi-pole plug contact comfortably bring to comparatively large values.

Die dargestellten Ausführungsbeispiele zeigen Anwendungen der Erfindung auf Leiteranordnung in Form von Flachkabeln mit weichflexibler bzw. weichelastischer Isolierung und darin eingebetteten, ebenfalls entsprechend flexiblen Adern als zu kontaktierende Leiter. Es kommen jedoch grundsätzlich auch andersartige Leiteranordnungen in Betracht, z.B. Leitungen mit formsteifen oder im wesentlichen nur plastisch verformbaren, insbesondere draht- oder stangenförmigen Leitern. Auch hinsichtlich der Verformbarkeit der Isolierung bestehen breite Variationsmöglichkeiten. So wird zwar vielfach ein beträchtlicher elastischer Verformungsbereich des Isoliermaterials mit bestimmten Werten des Elastizitätsmoduls jedenfalls im Bereich der die Steckkontakte aufnehmenden Isolierungsausnehmungen anzustreben sein, um die Kontaktgabe und die formschlüssige Lagesicherung der Steckkontakte unter Vorspannung zu gewährleisten, jedoch ist es grundsätzlich auch denkbar, diese Anpress- und Vorspannfunktion ganz oder teilweise den dann entsprechend federelastisch ausgebildeten Steckkontakten oder auch den Leitern zuzuweisen, wobei die Auswahl des Isoliermaterials nach anderen Gesichtspunkten freizügig möglich wird. Die erfindungsspezifischen Vorteile können dabei unter Berücksichtigung geeigneter, an sich üblicher konstruktiver Anpassungen verwirklicht werden.The exemplary embodiments shown show applications of the invention on a conductor arrangement in the form of flat cables with flexible or flexible insulation and embedded, likewise correspondingly flexible cores as conductors to be contacted. However, other types of conductor arrangements are also possible, e.g. Lines with dimensionally stable or essentially only plastically deformable, in particular wire or rod-shaped conductors. There is also a wide range of options with regard to the deformability of the insulation. Thus, in many cases a considerable elastic deformation range of the insulating material with certain values of the modulus of elasticity in the area of the insulation recesses receiving the plug contacts will have to be aimed at in order to ensure contact and the form-fitting securing of the plug contacts under pretension, but it is also fundamentally conceivable to and assign the biasing function wholly or in part to the correspondingly spring-loaded plug contacts or also to the conductors, the selection of the insulating material being freely possible from other points of view. The advantages specific to the invention can be realized taking into account suitable, customary structural adaptations.

Bei der Ausführung nach Fig.1 und 2 besteht das Flachkabel 1 aus einer Isolierung 2, in die zwei nebeneinander verlaufenden Adern 3a und 3b eingebettet sind. Im Bereich der Anschlussstelle 4 sind zwischen den beiden Adern die Isolierung durchgreifende, symmetrisch zur Längsmittelachse des Kabels angeordnete Ausnehmungen 2a und 2b eingestanzt, die jeweils an einander diametral gegenüberliegenden Randbereichen Kontaktstellen K beider Adern freilegen.In the embodiment according to FIGS. 1 and 2, the flat cable 1 consists of an insulation 2, in which two wires 3a and 3b running next to one another are embedded. In the area of the connection point 4, the insulation penetrating between the two wires is symmetrical to the longitudinal central axis of the Cable-arranged recesses 2a and 2b are punched out, each of which exposes contact points K of both wires at diametrically opposite edge regions.

Ein in die Anschlussstelle 4 eingesetzter, zweipoliger Stecker 5 mit zwei Anschlussleitungen 6a und 6b umfasst einen Isolierkörper 7, innerhalb dessen die Endabschnitte 8 der Anschlussleitungen durch Klemm- oder Lötverbindungen 9 an je ein zugehöriges Kontaktelement 10a bzw. 10b angeschlossen sind. Letztere bilden zusammen mit je einem im wesentlichen zylindrischen Isolierelement 11a bzw. 11b Steckkontakte 12a bzw. 12b, die mit ihren oberen Endabschnitten stoffschlüssig in den Stecker-Isolierkörper 7 eingbettet sind und mit ihren unteren Abschnitten die Isolierungsausnehmungen 2a bzw. 2b durchgreifen. An den unteren Enden der Steckkontakte bilden die Isolierelemente 11a, 11b je einen kegelförmigen Kopf 13, der mit seiner oberen Schulter an der Unterseite der Kabelisolierung anliegt und den Stecker in seiner Anschlussstellung sichert. Der Kopfdurchmesser ist so bemessen, dass die elastische Nachgiebigkeit der Isolierung das Durchgreifen der Ausnehmungen 2a und 2b mit erträglichem Kraftaufwand und ohne Beschädigung der Isolierung ermöglicht. Im unteren Abschnitt der Steckkontakte ist jeweils eine peripheral verlaufende Einsenkung 14 gebildet, in die der freiliegende Kontaktstellenbereich der beiden Adern unter Bildung einer vergleichsweise grossen Berührungsfläche im Bereich des betreffenden Kontaktelementes 10a bzw. 10b einrastet.A two-pole plug 5 with two connection lines 6a and 6b inserted into the connection point 4 comprises an insulating body 7, within which the end sections 8 of the connection lines are connected by clamped or soldered connections 9 to an associated contact element 10a or 10b. The latter, together with an essentially cylindrical insulating element 11a or 11b, form plug contacts 12a or 12b, which are embedded with their upper end sections in the plug insulating body 7 and with their lower sections penetrate the insulating recesses 2a or 2b. At the lower ends of the plug contacts, the insulating elements 11a, 11b each form a conical head 13, which rests with its upper shoulder on the underside of the cable insulation and secures the plug in its connection position. The head diameter is dimensioned in such a way that the elastic flexibility of the insulation enables the recesses 2a and 2b to be gripped through with tolerable effort and without damaging the insulation. In the lower section of the plug contacts, a peripheral depression 14 is formed, into which the exposed contact point area of the two wires engages, forming a comparatively large contact area in the area of the contact element 10a or 10b concerned.

Wie aus der Darstellung in Fig.2 ersichtlich, sind die Steckkontakte 12a und 12b an ihrem Querschnittsumfang mit einander in Richtung quer zu ihrer Verbindungslinie paarweise gegenüberliegenden Kontakt- und Isolierelementen versehen, die ausserdem in Bezug auf diese Verbindungslinie zueinander antimetrisch angeordnet sind. Dadurch wird sichergestelltm dass trotz der Freilegung symmetrischer Kontaktstellen K beider Adern innerhalb beider Isolierungsausnehmungen jeder Steckkontakt bzw. jedes Kontaktelement nur mit jeweils einer zugeordneten Ader in Verbindung treten kann. Es versteht sich, dass gegebenenfalls mehrere Kontaktelemente an einem Steckkontakt nebeneinanderliegend vorgesehen werden können, sofern die vorstehende Bedingung für die selektive Aderkontaktierung gewahrt bleibt.As can be seen from the illustration in FIG. 2, the plug contacts 12a and 12b are provided on their cross-sectional circumference with contact and insulating elements which are opposite each other in pairs in the direction transverse to their connecting line and which are also arranged antimetrically with respect to this connecting line. This ensures that, despite the exposure of symmetrical contact points K of both wires within both insulation recesses, each plug contact or contact element can only connect to one assigned wire. It goes without saying that, if necessary, a plurality of contact elements can be provided next to one another on a plug contact, provided that the above condition for selective wire contacting is maintained.

Im bisher beschriebenen Umfang entspricht die Kontaktanordnung nach Fig.3 der Ausführung nach Fig.1 und 2, weshalb für die Steckkontakte und die sie in der dargestellten Lage aufnehmenden Isolierungsausnehmungen die gleichen Bezugszeichen eingetragen sind. Die Ausführung nach Fig.3 ist jedoch darüberhinaus mit Hilfe zusätzlicher Isolierungsausnehmungen 2c und 2d, die jeweils unmittelbar neben den Ausnehmungen 2a bzw. 2b angeordnet und mit diesen durch offene Durchgangsbereiche 2e bzw. 2f verbunden sind, zu einer ein- und ausschaltbaren Kontaktverbindung weiterentwickelt. Zum Umstellen aus der angedeuteten Einschalt- bzw. Kontaktstellung in die Ausschaltstellung braucht lediglich der Anschlussstecker mit seinen Steckkontakten 12a und 12b in Richtung des Pfeils P3 verschoben zu werden, bis die Steckkontakte in die Isolierungsausnehmungen 2c bzw. 2d einrasten. Da letztere von geringerem Durchmesser und daher ohne randseitige Verbindung mit den Kabeladern sind, ist kein Kontakt gegeben. Ein zusätzlicher Axialschlitz 2g an der Ausnehmung 2c sowie eine zusätzliche Trennstelle 2h zwischen den Ausnehmungen 2a und 2d sorgen für ausreichende Nachgiebigkeit der Isolierung in Kabelquerrichtung, so dass die Verschiebung der Steckkontakte keinen zu grossen Widerstand findet, andererseits aber eine ausreichende elastische Quervorspannung der Isolierung erhalten bleibt.To the extent described so far, the contact arrangement according to FIG. 3 corresponds to the embodiment according to FIGS. 1 and 2, which is why the same reference numerals are entered for the plug contacts and the insulation recesses receiving them in the position shown. However, the embodiment according to FIG. 3 is further developed into a contact connection that can be switched on and off with the aid of additional insulation recesses 2c and 2d, which are each arranged directly next to the recesses 2a and 2b and connected to them by open passage areas 2e and 2f. To switch from the indicated switch-on or contact position to the switch-off position, only the connector with its plug contacts 12a and 12b is required to be moved in the direction of arrow P3 until the plug contacts snap into the insulation recesses 2c or 2d. Since the latter are of smaller diameter and therefore have no edge connection to the cable cores, there is no contact. An additional axial slot 2g on the recess 2c and an additional separating point 2h between the recesses 2a and 2d ensure sufficient flexibility of the insulation in the transverse direction of the cable, so that the displacement of the plug contacts does not find too great resistance, but on the other hand a sufficient elastic transverse preload of the insulation is retained .

Bei der Ausführung nach Fig.4 ist in der Isolierung eine Aussparung gebildet, die aus drei miteinander über Durchgangsbereiche 402d verbundenen Isolierungsausnehmungen 402a, 402b und 402c besteht. Innerhalb dieser Aussparung ist der zwei Kontaktelemente 412a und 412b aufweisende Steckkontakt zwischen verschiedenen Stellungen bewegbar angeordnet, wobei die Kontaktelemente in entsprechende Isolierungsausnehmungen einrasten und damit in der betreffenden Stellung festgehalten sind. Die Isolierungsausnehmungen bilden Kontaktstellen K für die elektrische Verbindung der Kontaktelemente mit jeweils einem zugehörigen Leiter. Es ergibt sich daher eine aderselektive Kontaktierung, wobei vorteilhafterweise einfache und billige Kontaktelemente verwendet werden können.In the embodiment according to FIG. 4, a recess is formed in the insulation, which consists of three insulation recesses 402a, 402b and 402c which are connected to one another via passage areas 402d. Within this recess, the plug contact having two contact elements 412a and 412b is arranged to be movable between different positions, the contact elements snapping into corresponding insulation recesses and thus being held in the relevant position. The insulation recesses form contact points K for the electrical connection of the contact elements, each with an associated conductor. This results in a wire-selective contacting, whereby advantageously simple and inexpensive contact elements can be used.

Diese Kontaktanordnung ist als Umschalter mit kontaktfreier Mittelstellung ausgebildet. Die Kontaktelemente 412a und 412b können durch Ueberführung zwischen den Stellungen I und II in jeweils gegensinniger Polung mit den Leitern verbunden sowie ferner durch Verschieben in die ebenfalls als Rastausnehmungen ausgebildeten Durchgangsbereiche 402d in die kontaktfreie Mittelstellung gebracht werden. Massgebend für die Schaltwirkung sind grundsätzlich verschiedene Anordnungen von Isolierungsausnehmungen, die je einer Schaltstellung zugeordnet sind. Speziell im Beispiel ist die Ausnehmung 402b mit dem Vorteil einer einfachen Gestaltung den beiden Ausnehmungsanordnungen gemäss Schaltstellung I und II gemeinsam zugeordnet. Im Beispielsfall umfasst die Verstellbewegung der Konttaktelemente bzw. des Steckers eine translatorische und eine rotatorische Komponente. Grundsätzlich sind jedoch auch Ausführungen mit im wesentlichen nur translatorischer oder rotatorischer Schaltbewegung anwendbar. Insbesondere können die Kontaktelemente dabei auch in an sich bekannter Weise an einem gemeinsamen Steckelement mit geeignetem Isolierkörper angeordnet sein. Dabei kommen z.B. auch Gestaltungen in Betracht, bei denen die Aussparung im Kabel einen vergleichsweise grossen, zentralen Durchgangsbereich aufweist, an den sich mehrere kleinere Rastausnehmungen mit Kontaktstellen zur Aufnahme der Kontaktelemente anschliessen.This contact arrangement is designed as a changeover switch with a contact-free central position. The contact elements 412a and 412b can be connected to the conductors by transferring between positions I and II in opposite polarity can also be brought into the contact-free central position by shifting into the passage areas 402d, which are also designed as latching recesses. Decisive for the switching effect are fundamentally different arrangements of insulation recesses, each of which is assigned to a switching position. In the example in particular, the recess 402b is associated with the two recess arrangements according to switch position I and II with the advantage of a simple design. In the example, the adjustment movement of the contact elements or the plug comprises a translatory and a rotary component. In principle, however, designs with essentially only translatory or rotary switching movement can also be used. In particular, the contact elements can also be arranged in a manner known per se on a common plug element with a suitable insulating body. For example, designs are also possible in which the cutout in the cable has a comparatively large, central passage area, to which several smaller snap-in recesses with contact points for receiving the contact elements are connected.

Bei der Ausführung nach Fig.5 und 6 ist ein Breit-Flachkabel 501 mit Isolierung 502 und verstärktem Isolierungs-Mittelsteg 501a sowie mit zwei Adern 503a und 503b vorgesehen. Eine solche Ausführung kommt insbesondere für höhere Betriebsspannungen mit Vorteil in Betracht. Hier bilden zwei nur in Kabelquerrichtung mit gegenseitigem Abstand angeordnete Isolierungsausnehmungen 502a und 502b nur mit je einer zugeordneten Ader eine Kontaktstelle K, so dass einfache, durchgehend leitende Steckkontakte verwendet werden können.In the embodiment according to FIGS. 5 and 6, a wide flat cable 501 with insulation 502 and reinforced central insulation web 501a and with two wires 503a and 503b is provided. Such an embodiment is particularly advantageous for higher operating voltages. Here, two insulation recesses 502a and 502b, which are only spaced apart in the transverse direction of the cable, form a contact point K with only one associated wire each, so that simple, continuously conductive plug contacts can be used.

Auch diese Kontaktanordnung ist mit Hilfe von zusätzlichen Isolierungsausnehmungen 502c und 502d, die mit den Ausnehmungen 502a bzw. 502b überlappend angeordnet sind, ein- und ausschaltbar gestaltet. Die Schaltbewegung der Steckkontakte bzw. des - hier nicht besonders dargestellten - Steckers ist jedoch infolge der gewählten Umrissgestaltung und gegenseitigen Lage der Ausnehmungsanordnungen 502a/502c sowie 502b/502d gemäss Pfeilen P5a und P5b rotatorisch, was gegebenenfalls erwünscht sein kann.This contact arrangement is also designed to be switchable on and off with the aid of additional insulation recesses 502c and 502d, which are arranged to overlap with the recesses 502a and 502b. However, the switching movement of the plug contacts or of the plug (not shown here in particular) is rotational as a result of the selected outline design and mutual position of the recess arrangements 502a / 502c and 502b / 502d according to arrows P5a and P5b, which may be desirable.

Bei der Kontaktanordnung nach Fig.7 und 8 sind zwei Isolierungsausnehmungen 702a und 702b vorhanden, deren Umfang mit Abstand von zwei Flachkabelleitern 703a, 703b verläuft. Zwei zugehörige Steckkontakte 712a und 712b sind an in Kabelquerrichtung zueinander gegensinnig orientierten Umfangsbereichen mit je einem schneidenförmig vorstehenden Kontaktelement 710a bzw. 710b versehen, dass sich längs des in die betreffende Isolierungsausnehmung eingreifenden Steckkontaktabschnittes erstreckt. Die jeweils zu den Kontaktelementen 710a, 710b diametral angeordneten Bereiche des Querschnittsumfangs der beiden Steckkontakte sind isolierend ausgebildet bzw. mit zu den Kontaktelementen komplementären Isolierelementen versehen. Auf diese Weise sind die Kontaktelemente und Isolierbereiche bezüglich der Leiteranordnung zueinander antimetrisch angeordnet, so dass jedes Kontaktelement beim Einführen der durch einen (nicht dargestellten) Steckerkörper starr miteinander verbundenen Steckkontakte 712a, 712b in die Isolierungsausnehmungen nur mit der ihm zugeordneten Kabelader 703a bzw. 703b in Kontakt treten kann. Hierbei durchschneiden die äusseren Längskanten der Kontaktelemente die vergleichsweise dünne Isoliermaterialschicht an der engsten Stelle zwischen Kontaktstecker und Ader, so dass die Schneidkanten eine sichere Kontaktierung bewirken.7 and 8, there are two insulation recesses 702a and 702b, the circumference of which extends at a distance from two flat cable conductors 703a, 703b. Two associated plug contacts 712a and 712b are each provided with a cutting element protruding contact element 710a or 710b on circumferential areas oriented in opposite directions to one another in the cable transverse direction, which extends along the plug contact section engaging in the relevant insulation recess. The regions of the cross-sectional circumference of the two plug contacts which are arranged diametrically with respect to the contact elements 710a, 710b are designed to be insulating or are provided with insulating elements which are complementary to the contact elements. In this way, the contact elements and insulating regions are arranged antimetrically to one another with respect to the conductor arrangement, so that each contact element, when inserting the plug contacts 712a, 712b rigidly connected to one another by a plug body (not shown) into the insulation recesses, only with the one assigned to it Cable wire 703a or 703b can come into contact. Here, the outer longitudinal edges of the contact elements cut through the comparatively thin layer of insulating material at the narrowest point between the contact plug and the wire, so that the cutting edges ensure reliable contacting.

Bei der Ausführung nach Fig.9 sind zwei Steckkontakte 912a und 912b mit schneidenförmigen Kontaktelementen 910a bzw. 910b vorgesehen, wobei jedoch jeweils an zwei einander diametral entgegengesetzten Bereichen des Querschnittsumfanges der Steckkontakte je eine vorstehende Kontaktschneide vorhanden ist. Gleichwohl ist auf vorteilhaft einfache Weise dafür gesorgt, dass der in eine Isolierungsausnehmung eingeführte Steckkontakt durch sein Kontaktelement nur mit derjenigen Ader 903a bzw. 903b in Verbindung treten kann, welche dieser Isolierungsausnehmung zugeordnet ist. Dies ist dadurch erreicht, dass die beiden Isolierungsausnehmungen in Kabelquerrichtung gegensinnig versetzt innerhalb der Isolierung zwischen den beiden Adern angeordnet sind, nämlich mit unterschiedlichen beiderseitigen Abständen A und B zwischen Steckkontaktumfang und benachbarter Ader. Der Ueberstand der Kontaktschneiden an den Steckkontakten ist so bemessen, dass jeweils nur die dünnere Isoliermaterialschicht gemäss Abstand B von den Kontaktschneiden zur Kontaktgabe durchtrennt werden kann. Diese Ausführung hat den Vorteil einer besonders einfachen Gestaltung und günstigen Herstellbarkeit der Steckkontakte.In the embodiment according to FIG. 9, two plug contacts 912a and 912b are provided with blade-shaped contact elements 910a and 910b, however a projecting contact cutting edge is present in each case on two diametrically opposite regions of the cross-sectional circumference of the plug contacts. Nevertheless, it is ensured in an advantageously simple manner that the plug contact inserted into an insulation recess can only connect through its contact element to the wire 903a or 903b which is assigned to this insulation recess. This is achieved in that the two insulation recesses are arranged offset in opposite directions in the transverse direction of the cable within the insulation between the two wires, namely with different mutual distances A and B between the plug contact circumference and the adjacent wire. The protrusion of the contact cutting edges on the plug contacts is dimensioned such that only the thinner layer of insulating material can be severed according to distance B from the contact cutting edges for making contact. This version has the advantage of a particularly simple design and inexpensive manufacturability of the plug contacts.
