Description

Die Erfindung betrifft ein elektrisches Kontaktelement einer elektrischen Kabelsteckverbindung in Schneidklemmtechnik mit einer flächigen Gabelfeder für die Schneidklemmkontaktierung eines elektrischen Kabels sowie mit einer Steckeraufnahme, in die ein Stecker der elektrischen Kabelsteckverbindung einschiebbar ist.The invention relates to an electrical contact element of an electrical cable connector in insulation displacement technology with a flat fork spring for insulation displacement contacting an electrical cable and with a plug receptacle into which a plug of the electrical cable connector can be inserted.

Ein derartiges elektrisches Kontaktelement für die sogenannte Schneidklemmtechnik ist aus der DE-PS 39 29 928 bekannt. Die Kontaktelemente werden aus einem Blech ausgestanzt und entsprechend der vorgegebenen Form gebogen. Ein derart hergestelltes elektrisches Kontaktelement wird dann in einer entsprechenden Kammer eines Kunststoffgehäuses der Kabelsteckverbindung angeordnet, wonach das zugehörige elektrische Kabel an dem elektrischen Kontaktelement in Schneidklemmtechnik kontaktiert wird. Zu diesem Zweck weist das elektrische Kontaktelement wenigstens eine Gabelfeder auf, die zwischen sich einen Einführschlitz definiert, wobei die einander zugewandten Kanten der beiden Gabelfederschenkel angeschärft sind. Um das elektrische Kabel zu kontaktieren, wird dieses in den Einführschlitz der Gabelfeder eingeführt, so daß die Schneiden der beiden Gabelfederschenkel die Kabelisolierung derart einritzen, daß sie mit dem elektrischen Leiter in elektrischen Kontakt gelangen. Die beiden Gabelfederschenkel üben dabei eine Klemmkraft auf den elektrischen Leiter aus, so daß dieser in dem Einführschlitz gehalten ist.Such an electrical contact element for the so-called insulation displacement technology is known from DE-PS 39 29 928. The contact elements are punched out of sheet metal and bent in accordance with the specified shape. An electrical contact element produced in this way is then arranged in a corresponding chamber of a plastic housing of the cable plug connection, after which the associated electrical cable is contacted on the electrical contact element using insulation displacement technology. For this purpose, the electrical contact element has at least one fork spring, which defines an insertion slot between them, the mutually facing edges of the two fork spring legs being sharpened. In order to contact the electrical cable, it is inserted into the insertion slot of the fork spring, so that the cutting edges of the two fork spring legs scratch the cable insulation in such a way that they come into electrical contact with the electrical conductor. The two fork spring legs exert a clamping force on the electrical conductor so that it is held in the insertion slot.

Ein solches Kontaktelement nach dem Stand der Technik weist darüber hinaus eine Steckeraufnahme auf, in die ein Stecker der elektrischen Steckverbindung einschiebbar ist. Als Steckeraufnahme dienen paarweise angeordnete Federzungen, zwischen die beispielsweise der Kontaktstift eines Steckers der elektrischen Steckverbindung zur Kontaktierung eingeschoben werden kann. Nachteilig ist dabei, daß ein solches Schneidkontaktelement nicht in der Lage ist, hohe Ströme bis zu 16 Ampere zu übertragen und daß sich durch den hohen Übergangswiderstand eine starke Erwärmung des Kontaktelementes in der Steckzone ergibt.Such a contact element according to the prior art also has a plug receptacle into which a plug of the electrical plug connection can be inserted. Spring tongues arranged in pairs serve as the plug receptacle, between which, for example, the contact pin of a plug of the electrical plug connection can be inserted for contacting. The disadvantage here is that such a cutting contact element is not able to transmit high currents of up to 16 amperes and that the contact resistance in the plug-in zone is greatly heated by the high contact resistance.

Der Erfindung liegt in Anbetracht dieses Standes der Technik die Aufgabe zugrunde, ein Kontaktelement der eingangs genannten Art derart zu verbessern, daß es für die Aufnahme von Leiterquerschnitten zwischen 0,75 mm² und 1,5mm² universell geeignet ist und hohe Ströme, wie zum Beispiel bis zu 16 Ampere für einen Leiterquerschnitt von 1,5mm² bei geringerer Erwärmung in der Steckzone überträgt.In view of this prior art, the invention has for its object to improve a contact element of the type mentioned in such a way that it is universally suitable for receiving conductor cross sections between 0.75 mm² and 1.5 mm² and high currents, such as up to to 16 amps for a conductor cross section of 1.5mm² with less heating in the plug-in zone.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Steckeraufnahme eine Flachsteckhülse ist. Anstelle der bisher bekannten Federzungen wird kombinativ erstmalig in der Schneidklemmtechnik eine Flachsteckhülse als Steckeraufnahme vorgeschlagen, die für eine erhebliche Minderung des Übergangswiderstandes sorgt und das Kontaktelement in Schneidklemmtechnik geeignet macht, Ströme bis zu 16 Ampere zu übertragen. Weiter ist vorteilhaft, daß die Verbindung des Anschlusses mit einem Flachstecker leicht steckbar ist, so daß sich eine universelle Anwendbarkeit, beispielsweise in der Auto-Industrie und Weißgeräte-Industrie ergibt. Die Sicherheit der neuen Anschlußtechnik ist gegenüber dem Stand der Technik erhöht.The object is achieved in that the connector receptacle is a flat receptacle. Instead of the previously known spring tongues, a flat receptacle is proposed for the first time in combination in insulation displacement technology as a plug receptacle, which ensures a considerable reduction in contact resistance and makes the contact element in insulation displacement technology suitable for transmitting currents up to 16 amperes. It is also advantageous that the connection of the connection with a flat plug can be plugged in easily, so that there is universal applicability, for example in the auto industry and white goods industry. The security of the new connection technology is increased compared to the prior art.

Vorzugsweise besitzt die Flachsteckhülse einen Unterbringungsraum für den Flachstecker. Der Unterbringungsraum besteht dabei aus einer Fußplatte mit zwei Seitenwänden, deren beiden freien Ränder oberhalb der Fußplatte nach innen abgewinkelt sind, wobei die Fußplatte eine Verriegelungsklemme mit einem Zuhaltungshaken aufweist, der in eine im Flachstecker gebildete Ausnehmung einrastet.The flat receptacle preferably has an accommodation space for the flat plug. The accommodation space consists of a base plate with two side walls, the two free edges of which are angled inward above the base plate, the base plate having a locking clamp with a tumbler hook which snaps into a recess formed in the tab connector.

Um die Herstellung des erfindungsgemäßen Kontaktelementes in einfacher Weise aus einem ebenen Blechstanzteil im wesentlichen durch Biegevorgänge zu ermöglichen, ist es gemäß einer Ausgestaltung der Erfindung vorteilhaft, wenn die Gabelfeder und die Flachsteckhülse eine gemeinsame Fußplatte mit seitlichen Materialansätzen bestimmter Formgebung besitzen, die durch aufeinanderfolgende Biegevorgänge sowohl zur Erstellung des Unterbringungsraums der Flachsteckhülse als auch der Ausbildung der Gabelfedern geeignet sind. Die Gabelfedern weisen dabei zweckmäßigerweise eine Durchbrechung auf, die im wesentlichen die Fortsetzung des Einführschlitzes unter Belassung eines Zwischensteges der Gabelfeder zwischen dem Einführschlitz und der Durchbrechung bildet, um bei gleichbleibender Klemmkraft den Federweg und damit die Flexibilität der Gabelfederschenkel zu vergrößern, so daß insgesamt die Schneidklemmkontaktierung des elektrischen Kabels verbessert ist.In order to enable the contact element according to the invention to be produced in a simple manner from a flat sheet metal stamping essentially by bending processes, it is advantageous according to one embodiment of the invention if the fork spring and the flat receptacle have a common base plate have lateral material approaches of certain shapes, which are suitable for the creation of the accommodation space of the flat receptacle and the formation of the fork springs by successive bending processes. The fork springs expediently have an opening which essentially forms the continuation of the insertion slot, leaving an intermediate web of the fork spring between the insertion slot and the opening, in order to increase the spring travel and thus the flexibility of the fork spring legs with a constant clamping force, so that overall the insulation displacement contact of the electrical cable is improved.

Das Kontaktelement der Erfindung ist vorgesehen, im Rahmen des "RAST 5"-Programms für Hausgeräte eingesetzt zu werden, wo es besonders darauf ankommt, einen Kontakt für Leiterquerschnitte von 0,75 bis 1,5mm² zu erstellen, der große Ströme bis zu 16 Ampere ohne nennenswerte Erwärmung in der Steckzone übertragen kann.The contact element of the invention is intended to be used in the "RAST 5" program for domestic appliances, where it is particularly important to create a contact for conductor cross sections of 0.75 to 1.5 mm², which can handle large currents up to 16 amperes can transmit in the plug-in zone without significant heating.

Weitere Einzelheiten, Merkmale und Vorteile des Gegenstandes der Erfindung ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der ein erfindungsgemäßes Kontaktelement dargestellt ist. In der Zeichnung zeigt:

Further details, features and advantages of the subject matter of the invention result from the following description of the associated drawing, in which a contact element according to the invention is shown. The drawing shows:
Fig. 1
a contact element of an electrical cable connector in a front view,
Fig. 2
1 in top view and
Fig. 3
3 shows a section according to AA of the contact element of FIG. 2.

Das dargestellte Kontaktelement 1 besteht aus einem ebenen Blechstanzteil, aus dem die endgültige Form durch aufeinanderfolgende Biegevorgänge gebogen wird, wie sie sich aus den Figuren 1, 2 und 3 der Zeichnung ergibt.The contact element 1 shown consists of a flat stamped sheet metal part, from which the final shape is bent by successive bending operations, as can be seen in FIGS. 1, 2 and 3 of the drawing.

Dieses elektrische Kontaktelement 1 weist frontseitig eine Steckeraufnahme 2 in Form einer Flachsteckhülse 2 auf, deren Fußplatte 3 rückwärtig zur Ausbildung einer Gabelfeder 4 für die Schneidklemmkontaktierung eines elektrischen Kabels ausgebildet ist. Konkret besitzt die in der Zeichnung dargestellte Ausführungsform zwei Gabelfedern im Abstand zueinander, die jeweils aus zwei Gabelfederschenkeln 5 bestehen, die zwischen sich einen Einführschlitz 6 für das elektrische Kabel definieren.This electrical contact element 1 has on the front a plug receptacle 2 in the form of a flat receptacle 2, the base plate 3 of which is formed at the rear to form a fork spring 4 for the insulation displacement contacting of an electrical cable. Specifically, the one shown in the drawing Embodiment two fork springs spaced apart, each consisting of two fork spring legs 5, which define an insertion slot 6 between them for the electrical cable.

Weiterhin weisen die Gabelfedern 4 jeweils eine längliche, schlitzartige Durchbrechung 7 auf, welche bis dicht an den Einführschlitz 6 unter Belassung eines Zwischensteges 8 heranreicht. Diese Durchbrechung 7 läuft zum Einführschlitz 6 hin spitz zu, während sich die Durchbrechung 7 zum anderen Ende hin ebenfalls verjüngt.Furthermore, the fork springs 4 each have an elongated, slot-like opening 7, which extends as close as possible to the insertion slot 6, leaving an intermediate web 8. This opening 7 tapers towards the insertion slot 6, while the opening 7 also tapers towards the other end.

Zum Kontaktieren des elektrischen Kabels wird dieses von oben in den Einführschlitz 6 hineingesteckt, wobei sich aufgrund der Anschärfung der Kanten die Gabelfederschenkel 5 in die Isolierung des elektrischen Kabels einschneiden, bis die Gabelfederschenkel 5 am elektrischen Leiter zur Anlage kommen und somit den elektrischen Kontakt herstellen.To contact the electrical cable, this is inserted from above into the insertion slot 6, the fork spring legs 5 cutting into the insulation of the electrical cable due to the sharpening of the edges, until the fork spring legs 5 come into contact with the electrical conductor and thus establish the electrical contact.

Aus Fig. 3 ist ersichtlich, daß die Fußplatte 3 der Gabelfeder 4 frontseitig zur Ausbildung der Flachsteckhülse 2 verlängert ist und mit seitlichen Ansätzen in der Ebene versehen ist, so daß durch Biegen und Stanzen vor der Gabelfeder 4 die Flachsteckhülse 2 erstellbar ist. Diese weist folglich die Fußplatte 3 mit zwei senkrecht hochgebogenen Seitenwänden 9, 10 auf, deren beiden freien Ränder 11, 12 nach innen eingebogen sind, um einen kastenförmigen Unterbringungsraum für einen nicht dargestellten Flachstecker zu bilden, der von der Frontseite her eingeschoben werden kann. Um ein gleitendes Einschieben mit leichter Aufsteckkraft zu gewährleisten, sind die freien Ränder 11, 12 mit einer geringen Einprägung versehen, so daß sich ein bogenförmiger Verlauf ergibt. Jegliches Spiel zwischen dem Flachstecker und dem aus der Fußplatte 3, den beiden Seitenwänden 9, 10 sowie den freien Rändern 11, 12 gebildeten Unterbringungsraum ist vermieden, wobei durch die Einbiegung der freien Rändern ein guter Kontakt zwischen der Flachsteckhülse 2 und dem Flachstecker gewährleistet ist (Einbiegung ersichtlich in Fig. 3).From Fig. 3 it can be seen that the base plate 3 of the fork spring 4 is extended at the front to form the flat receptacle 2 and is provided with lateral approaches in the plane, so that the flat receptacle 2 can be created by bending and punching in front of the fork spring 4. This consequently has the base plate 3 with two vertically bent side walls 9, 10, the two free edges 11, 12 of which are bent inwards to form a box-shaped accommodation space for a flat plug, not shown, which can be inserted from the front. In order to ensure a sliding insertion with a slight push-on force, the free edges 11, 12 are provided with a slight indentation, so that there is an arcuate course. Any play between the flat plug and the accommodation space formed from the base plate 3, the two side walls 9, 10 and the free edges 11, 12 is avoided, with good contact between the flat plug sleeve 2 and the flat plug being ensured by the bending of the free edges ( Bending can be seen in Fig. 3).

In der Fußplatte 3 ist im Bereich der Flachsteckhülse 2 ein Zuhaltungshaken 13 herausgearbeitet, der mit einem Loch des Flachsteckers als Verriegelungsklemme zusammenwirkt. Um deren Lösbarkeit bereitzustellen, findet sich in der Fußplatte 3 ein im wesentlichen U-förmiger Ausschnitt 14, der eine Zunge bildet, die elastisch nach unten beweglich ist, um derart den Zuhaltungshaken aus seiner Verbindung mit dem Loch des Flachsteckers zu lösen.A tumbler hook 13 is worked out in the base plate 3 in the area of the flat receptacle 2, which interacts with a hole in the flat plug as a locking clamp. In order to provide their releasability, there is an essentially U-shaped cutout 14 in the base plate 3, which has a tongue forms, which is elastically movable downward in order to release the tumbler hook from its connection with the hole of the tab.
