Description
Die Erfindung betrifft einen Kabelsteckverbinder, insbesondere einem mehrpoligen Kabelsteckverbinder, gemäß den Merkmalen des Oberbegriffes des Patentanspruchs 1.The invention relates to a cable connector, in particular a multi-pole Cable connector, according to the features of the preamble of claim 1.
Aus der EP 0 684 666 B1 ist ein mehrpoliger Kabelsteckverbinder bekannt. Dieser Kabelsteckverbinder weist ein Kabelaufnahmeteil auf, in welches Einzellitzen zur axialen Kontaktierung ihrer steckerseitigen Endabschnitte durch die als Kontaktspieße ausgebildeten kabelseitigen Endbereiche eingesteckt werden. Beim Einstecken dringen die Kontaktspieße axial in die Einzellitzen ein, so daß dadurch die Kontaktierung hergestellt wird.A multi-pole cable connector is known from EP 0 684 666 B1. This Cable connector has a cable receiving part, in which individual strands for axial Contacting their plug-side end sections through the as contact spikes trained cable end areas are inserted. Penetrate when plugged in the contact skewers axially into the individual strands, so that the contact will be produced.
Bei der Untersuchung eines Kabelsteckverbinders über einen längeren Zeitraum hat sich gezeigt, daß die Kraft im Kontaktbereich des Kontaktspießes mit der Zeit abnimmt, so daß nach längerem Einsatz des Kabelsteckverbinders eine sichere Kontaktierung nicht mehr gewährleistet ist. Dadurch ist eine Datenübertragung oder die Stromversorgung über einen solchen Kabelsteckverbinder nicht immer gewährleistet, so daß es bei einem Ausfall der Datenübertragung oder der Stromversorgung zu unerwünschten Effekten, insbesondere zu sicherheitskritischen Situationen, kommen kann.When examining a cable connector over a long period of time, shown that the force in the contact area of the contact spike decreases with time, so that after a long period of use of the cable connector, no reliable contacting more is guaranteed. This is a data transfer or power supply Not always guaranteed via such a cable connector, so that it is one Failure of data transmission or power supply to undesirable effects, in particular to safety-critical situations.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Kabelsteckverbinder der eingangs genannten Art für den Anschluß beliebig konfigurierter ein- oder mehradriger Litzenkabel zu schaffen, bei dem die dauerhaft sichere Kontaktgabe sichergestellt ist.The invention is therefore based on the object of a cable connector at the beginning mentioned type for the connection of any configured single or multi-core stranded cable to create, in which the permanent safe contact is ensured.
Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst.This object is solved by the features of claim 1.
Erfindungsgemäß ist vorgesehen, daß das Kontaktmittel eine Schneidklemme ist, die das Kabelende derart in dem Kabelaufnahmeteil festsetzt, daß es nach der Verbindung unter mechanischer Vorspannung steht. Durch die Verwendung einer Schneidklemme ist gewährleistet, daß das Kabelende schnell und einfach, d. h., ohne große Vorarbeiten wie Abisolierung, in das Kabelaufnahmeteil eingesetzt werden kann. Die Schneidklemme gewährleistet bei der Montage, daß die äußere Isolation des Kabelendes aufgeschlitzt und ein elektrischer Kontakt mit der Seele des Kabels hergestellt wird. Dadurch, daß die Schneidklemme das Kabelende derart in dem Kabelaufnahmeteil festsetzt, daß es nach der elektrischen Verbindung unter einer dauerhaften mechanischen Vorspannung steht, ist auch die dauerhaft sichere Kontaktgabe sichergestellt, da aufgrund dieser Vorspannung das Kabelende immer in Richtung der Schneidklemme gedrückt wird oder umgekehrt. Dies ist gerade dann von hoher Bedeutung, wenn die Seele des Kabels aus Kupferlitze besteht, da Kupfer die Eigenschaft hat, zu wandern. Der Kabelsteckverbinder kann für lediglich ein einadriges Kabel verwendet werden, aber selbstverständlich auch für mehrere einzelne Kabel sowie auch für ein einziges mehrpoliges Kabel. Auf die Bauform des Kabelsteckverbinders (rund, quadratisch oder dergleichen) kommt es nicht an.According to the invention it is provided that the contact means is an insulation displacement terminal, which Cable end so fixed in the cable receiving part that it is under the connection mechanical preload. By using an insulation displacement clamp ensures that the cable end is quick and easy, i. i.e. without much preparatory work such as Stripping in which cable receptacle can be inserted. The insulation piercing clamp ensures during assembly that the outer insulation of the cable end is cut open and electrical contact is made with the core of the cable. Because the Insulation clamp fixes the cable end in the cable receiving part in such a way that it follows the electrical connection is under a permanent mechanical prestress, permanent, secure contact is also ensured, because of this Preload the cable end is always pressed in the direction of the insulation piercing or vice versa. This is especially important when the soul of the cable is out Copper braid exists because copper has the property to migrate. The cable connector can only be used for a single-core cable, but of course also for several individual cables as well as for a single multi-pole cable. On the Design of the cable connector (round, square or the like) does not come on.
In Weiterbildung der Erfindung weist das Kabelaufnahmeteil eine Leitungskammer auf, die in ihrem Querschnitt größer ist als der Querschnitt des Kabels. Zum einen wird dadurch das Kabelende beim Einführen in das Kabelaufnahmeteil längs der Leitungskammer geführt. Gleichzeitig hat das Kabelende nach dem Festsetzen in dem Kabelaufnahmeteil die Möglichkeit, sich beim Kontaktieren der Schneidklemme geringfügig zu bewegen, wodurch die mechanische Vorspannung entsteht. Im Durchdringungs- bzw. Kontaktierungsbereich ist, insbesondere in der X-Y-Ebene, keine Führung des Kabelendes entlang einer definierten Bahn erforderlich, wodurch eine einfache Gestaltung des Kabelaufnahmeteiles sowie dessen Bestückung gegeben ist. Ein weiterer Vorteil besteht in dem Einsatz unterschiedlich dicker Kabelenden.In a development of the invention, the cable receiving part has a line chamber, which is larger in cross section than the cross section of the cable. For one thing thereby the cable end when inserted into the cable receptacle along the Management chamber led. At the same time, the cable end after fixing in the Cable receiving part the possibility of contacting the insulation displacement terminal move slightly, which creates the mechanical preload. in the Penetration or contacting area, especially in the X-Y plane, is none Guide of the cable end along a defined path is required, creating a simple design of the cable receiving part and its assembly is given. On Another advantage is the use of cable ends of different thicknesses.
In Weiterbildung der Erfindung weist das Kabelaufnahmeteil eine Spannhülse auf. Diese Spannhülse kann entweder nach Einführung des Kabelendes in das Kabelaufnahmeteil eingesetzt werden oder schon bei der Einführung des Kabelendes in die Leitungskammer eingesetzt und von dem Kabelende durchdrungen werden. Nachdem das Kabelende in die Leitungskammer eingeführt worden ist, wird die Spannhülse insbesondere maschinell festgesetzt und fixiert so die Lage des Kabelendes in bezug auf das Kabelaufnahmeteil. Alternativ können auch, bevor das Kabelende eingesetzt würde, die Spannkeile als Widerhaken ausgestaltet sein, die nach dem Einsetzen des Kabelendes dieses halten. Schon bei diesem Montageschritt kann dafür gesorgt werden, daß dasjenige Stück des Kabelendes, welches sich in der Leitungskammer befindet, unter einer gewissen mechanischen Vorspannung steht. Dadurch erhöht sich die Wirksamkeit der Kontaktierung, da zusätzlich zu dieser Vorspannung noch die mechanische Vorspannung dazu kommt, die beim Kontaktieren mit der Schneidklemme entsteht. Außerdem bewirkt die Festsetzung des Kabelendes mittels der Spannhülse, daß das Kabelende beim Kontaktieren mit der Schneidklemme nicht aus der Leitungskammer hinausbewegt werden kann. Anstelle einer Spannhülse ist es selbstverständlich auch denkbar, das Kabel lösbar oder unlösbar in der Leitungskammer festzusetzen, wobei des letzte Stück des Kabels freibewegbar in der Leitungskammer bleibt. Bezüglich einer unlösbaren Festsetzung kann daran gedacht werden, das Kabel im oberen Ende der Leitungskammer festzukleben. Der Einsatz einer Spannhülse hat jedoch den Vorteil, daß diese sowohl maschinell eingesetzt als auch festgesetzt werden kann.In a development of the invention, the cable receiving part has an adapter sleeve. This The adapter sleeve can either be inserted into the cable receiving part after the cable end has been inserted be used or already when inserting the cable end into the line chamber used and penetrated by the cable end. After the cable end in the lead chamber has been inserted, the adapter sleeve is particularly mechanical fixed and thus fixes the position of the cable end with respect to the cable receiving part. Alternatively, the clamping wedges can also be used before the cable end is inserted Barbs are designed to hold this after inserting the cable end. Already in this assembly step it can be ensured that the piece of the Cable end, which is located in the line chamber, under a certain mechanical preload. This increases the effectiveness of the Contacting, because in addition to this preload, there is also the mechanical preload in addition, which arises when contacting the insulation displacement terminal. It also causes the fixing of the cable end by means of the adapter sleeve that the cable end at Contact with the insulation displacement clamp has not moved out of the line chamber can be. Instead of an adapter sleeve, it is of course also conceivable that Cable detachable or non-detachable in the line chamber, the last piece the cable remains freely movable in the line chamber. Regarding an unsolvable Fixing can be thought of in the upper end of the cable To glue the line chamber. However, the use of an adapter sleeve has the advantage that this can both be used mechanically and fixed.
In Weiterbildung der Erfindung ist die Schneidklemme in einem Schneidklemmenaufnahmemittel angeordnet und das Schneidklemmenaufnahmemittel mit dem Kabelaufnahmeteil verbindbar. So kann wie vorher beschrieben das Kabelende in das Kabelaufnahmeteil eingeführt und festgesetzt werden, wobei anschließend die Schneidklemme durch Zuführen des Schneidklemmenaufnahmemittels in den unteren Bereich der Leitungskammer eindringt und dort die Kontaktierung bewirkt. Zum Abschluß werden das Kabelaufnahmeteil und das Schneidklemmenaufnahmemittel miteinander verbunden (z. B. durch Verklipsen, Verschrauben, Verschweißen, Verkleben oder dergleichen), so daß der fertige Kabelsteckverbinder entsteht. Die Schneidklemme weist auf ihrer dem Kontaktbereich abgewandten Seite Anschlußmittel wie Kontaktstifte, Kontaktbuchsen oder dergleichen auf. Diese können freiliegen oder auch konzentrisch von einem Teil der Schneidklemmenaufnahmemittel umgeben sein.In a further development of the invention, the insulation displacement clamp is in one Arranged clamp receiving means and the cutting clamp receiving means connectable to the cable receptacle. The cable end can be as described above inserted and fixed in the cable receiving part, after which the Insulation displacement clamp by feeding the insulation displacement device into the lower one Penetrates the area of the line chamber and makes contact there. In conclusion the cable receiving part and the insulation displacement receiving means together connected (e.g. by clipping, screwing, welding, gluing or the like), so that the finished cable connector is created. The insulation displacement terminal points on its side facing away from the contact area, connection means such as contact pins, Contact sockets or the like. These can be exposed or concentric be surrounded by part of the insulation displacement receptacle.
In Weiterbildung der Erfindung verjüngt sich die Leitungskammer in ihren Endbereich (Kontaktbereich). Durch diese Verjüngung wird eine Queranordnung der Kabelende-Ausknickrichtung bewirkt, wodurch eine weitere Ausrichtung des Kabelendes zu der Federrichtung der Schneidklemme nicht mehr erforderlich ist. Weiterhin kann durch diese Verjüngung (keilförmige Gestaltung) der Leitungskammer diese mit Kabelenden (Adern) unterschiedlichen Durchmessers bestückt werden. Bei unterschiedlichen Durchmessern bewirkt die Verjüngung eine Führung des Kabelendes in die Richtung, daß das Kabelende eine solche Position einnimmt, in der es zuverlässig von der Schneidklemme durchdrungen werden kann.In a further development of the invention, the line chamber tapers into its end region (Contact area). Through this taper, a transverse arrangement of the Cable end buckling direction causes a further alignment of the cable end to the spring direction of the insulation displacement clamp is no longer required. Furthermore can due to this tapering (wedge-shaped design) of the line chamber Cable ends (wires) of different diameters can be fitted. At different diameters, the tapering leads the cable end in the direction that the cable end occupies such a position that it is reliable from the insulation displacement terminal can be penetrated.
In Weiterbildung der Erfindung weist die Leitungskammer einen rautenförmigen Querschnitt auf. Durch diese Ausgestaltung des Querschnittes der Leitungskammer ist gewährleistet, daß dem Kabelende einerseits ausreichend Platz zur leicht bogenförmigen Verformung zur Verfügung steht, andererseits aber auch eine Zentrierung stattfindet, die gewährleistet, daß beim Kontaktieren mit der Schneidklemme das Kabelende nicht so zurückweichen kann, daß keine Kontaktierung entsteht.In a further development of the invention, the line chamber has a diamond-shaped one Cross section on. This configuration of the cross section of the line chamber is ensures that the cable end on the one hand has enough space for the slightly arcuate Deformation is available, but on the other hand a centering takes place that ensures that the cable end is not so when contacting the insulation displacement terminal can recede that no contact is made.
In Weiterbildung der Erfindung sind die Mittellinien der Schneidklemme und der Leitungskammer fluchtend, parallel oder geneigt zueinander angeordnet. Durch die nahezu axiale bzw. im Idealfall axiale Durchdringung der Isolation des Kabelendes entsteht zwischen der Schneidklemme und der leitfähigen Seele des Kabelendes eine großflächige, hoch redundante, dauerhaft elastische und gasdichte elektrische Verbindung.In a development of the invention, the center lines of the insulation displacement and the Line chamber aligned, parallel or inclined to each other. Through the almost axial or, ideally, axial penetration of the insulation of the cable end one is created between the insulation displacement connector and the conductive core of the cable end Large, highly redundant, permanently elastic and gas-tight electrical Connection.
Ein Ausführungsbeispiel des erfindungsgemäßen Kabelsteckverbinders, auf das die Erfindung jedoch nicht beschränkt ist, ist im folgenden beschrieben und anhand der Figuren erläutert.An embodiment of the cable connector according to the invention, to which the However, the invention is not limited, is described below and using the Figures explained.

Figur 1 zeigt einen Kabelsteckverbinder 1 mit einem Kabelaufnahmeteil 2, in welches ein
Kabelende 3 eingeführt werden kann. Zu diesem Zweck ist in dem Kabelaufnahmeteil 2
eine Leitungskammer 4 vorhanden, deren Querschnitt (insbesondere Durchmesser)
geringfügig größer ist als der Durchmesser des Kabelendes 3. Im unteren Bereich des
Kabelaufnahmeteiles 2 ist eine Öffnung 5 (Schlitz) vorhanden, durch den eine noch zu
beschreibende Schneidklemme in die Leitungskammer 4 eingeführt werden kann. Im
oberen Bereich des Kabelaufnahmeteiles 2 ist eine Spannhülse 6 vorhanden, die einen
sich in axialer Richtung (Z-Richtung) erstreckenden Spannkeil 7 aufweist. Der Spannkeil
hat eine solche Erstreckung und Ausdehnung, daß er den verbleibenden Raum des
Querschnittes der Leitungskammer 4, der nicht von dem Kabelende 3 ausgefüllt wird,
zumindest teilweise ausfüllt und darüber hinaus einen ausreichenden Druck auf das
Kabelende 3 ausüben kann. Figure 1 shows a cable connector 1 with a cable receiving part 2, in which a
Der Zusammenbau des in Figur 1 gezeigten Kabelsteckverbinders 1 erfolgt wie folgt:The cable connector 1 shown in FIG. 1 is assembled as follows:
Das Kabelende 3 wird in Z-Richtung durch die Spannhülse 6 durchgefädelt und in die
Leitungskammer 4 des Kabelaufnahmeteiles 2 eingeführt. Die Spannhülse 6 wird dann
ebenfalls mit dem oberen Kragen des Kabelaufnahmeteiles 2 zusammengeführt und
verrastet derart, daß der Spannkeil 7 ein Zurückweichen des Kabelendes 3 verhindert.
Die keilförmige Verjüngung der Leitungskammer 4 in Z-Richtung verursacht, daß die
Spitze des Kabelendes 3 bezüglich einer Schneidklemme eine definierte Lage einnimmt
oder das entsprechend abgelängte Kabelende 3 mindestens einmal in X-Richtung leicht
ausknickt, d. h., daß das Kabelende 3 eine leicht bogenförmige oder auch S-förmige
Ausgestaltung annimmt. Durch die schlitzartige Öffnung 5 wird eine in einem
Schneidklemmenaufnahmemittel 8 angeordnete Schneidklemme 9 in die mit dem
Kabelende 3 bestückte Leitungskammer 4 eingeführt. Durch die über die Schneidklemme
9 aufgebrachte Axialkraft wird das freie Kabelende 3 zunächst zurückgedrängt und
dessen Ausknickung eingeleitet bzw. verstärkt, bis ein vollständiges Anliegen der
ausgeknickten Bereiche des Kabelendes 3 an den Wänden der Leitungskammer 4
stattfindet. In diesem Zustand wird dann die neutrale Faser der Seele des Kabelendes 3
so verformt, daß sie die Mittellinie der Schneidklemme 9 mindestens einmal bogenförmig
schneidet. Sobald infolge der Klemmkraft der Spannhülse 6 und zusätzlich infolge der
Reibung der Isolation des Kabelendes 3 an den Wänden der Leitungskammer die freien
Enden der Adern nicht weiter zurückweichen können, findet das Durchdringen der
Isolation und die elektrische Kontaktierung mit der Schneidklemme 9 statt. Anschließend
muß noch dafür gesorgt werden, daß das Kabelaufnahmeteil 2 mit dem
Schneidklemmenaufnahmemittel 8 dauerhaft und lösbar bzw. unlösbar miteinander
verbunden werden. Bei dem Schneidklemmenaufnahmemittel 8 kann es sich
beispielsweise um ein Teil des Kabelsteckverbinders handeln; denkbar ist aber auch, daß
die Schneidklemme 9 auf einer Platine einer elektronischen Schaltung angeordnet ist
oder aus einem Modul herausragt, wobei dann das Schneidklemmenaufnahmemittel 8 die
Platine oder das Gehäuse des Moduls wäre. Die axiale Mittellinie der Leitungskammer 4
kann auch schräg zu der Z- bzw. Y-Achse geneigt sein.The
Figur 2 zeigt den Kabelsteckverbinder 1 im Querschnitt A-A gemäß Figur 1. In dieser
Figur ist der rautenförmige Querschnitt der Leitungskammer 4 zu erkennen, wobei die
Maße d und D, d. h., die Erstreckung der rautenförmigen Leitungskammer 4 in X- bzw. Y-Richtung,
voneinander verschieden sind. Auf jeden Fall ist sicherzustellen, daß einer der
beiden Parameter d bzw. D oder beide Parameter geringfügig größer sind als der
Durchmesser des Kabelendes 3, damit dieses in der Leitungskammer 4 sich bogenförmig
beim Einsetzen verformen kann. Ein besonders vorteilhafter Fall ist dann gegeben, wenn
die Leitungskammer 4 die rautenförmige Gestalt aufweist und die Gleichung d gleich D
erfüllt ist. Dadurch sind besonders platzsparende Realisierungen möglich.
Selbstverständlich kann auch daran gedacht werden, daß die Leitungskammer 4 im
Querschnitt einen runden, einen ovalen, einen quadratischen, einen rechteckigen oder
einen solchen Querschnitt aufweist, der eine Kombination der genannten geometrischen
Querschnitte darstellt. Figure 2 shows the cable connector 1 in cross section A-A according to Figure 1. In this
