Description

Die Erfindung betrifft einen Kabelsteckverbinder, insbesondere einem mehrpoligen Kabelsteckverbinder, gemäß den Merkmalen des Oberbegriffes des Patentanspruchs 1, Solch ein Kabelsteckverbinder ist aus EP-A-0 886 156 bekannt.The invention relates to a cable connector, in particular a multi-pole Cable connector, according to the features of the preamble of claim 1, Such a cable connector is known from EP-A-0 886 156.

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.From EP 0 684 666 B1 a multi-pole cable connector is known. This Cable connector has a cable receiving part, in which individual strands for axial Contacting their plug-side end sections by the contact spikes trained cable-side end portions are inserted. When inserting penetrate the Kontaktspieße axially in the individual strands, so that thereby contacting 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 investigating a cable connector for a long period of time has become shown that the force in the contact area of the contact spike decreases with time, so that after prolonged use of the cable connector secure contact not more is guaranteed. This is a data transfer or the power supply over such a cable connector is not always guaranteed, so that it at a Failure of data transmission or power supply to unwanted effects, especially 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, a cable connector of the above mentioned type for the connection of any configured single or multi-core stranded cable to create, in which the permanent secure 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 a cutting clamp, the Cable end so sets in the cable receiving part, that after connection under mechanical preload is. By using a cutting clamp is ensures that the cable end quickly and easily, d. h., without much preparation like Stripping, can be used in the cable receiving part. The cutting clamp ensures during assembly that the outer insulation of the cable end is slit and making electrical contact with the core of the cable. In that the Cutting clamp the cable end so fixed in the cable receiving part, that it after the electrical connection is under a permanent mechanical bias, is also the permanent secure contact ensured, because of this Biasing the cable end is always pressed in the direction of the insulation displacement terminal or vice versa. This is especially important when the soul of the cable is out Copper strand exists because copper has the property to migrate. The cable connector can be used for only a single core cable, but of course also for several individual cables as well as for a single multi-pole cable. On the Type of cable connector (round, square or the like) does not come at.

Gemäß 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.According to 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 during insertion into the cable receiving part along the Conduction chamber led. At the same time, the cable end after settling in the Cable receiving part the possibility of contacting the insulation displacement terminal to move slightly, whereby the mechanical preload arises. in the Penetration or contacting area, especially in the X-Y plane, no Guide the cable end along a defined path required, creating a simple design of the cable receiving part and its equipment is given. One Another advantage is the use of different thickness cable ends.

Gemäß 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.According to the invention, the conduit chamber tapers in its end region (Contact area). By this taper is a transverse arrangement of the Cable end-kinking direction causes, whereby a further alignment of the cable end to the spring direction of the insulation displacement clamp is no longer necessary. Furthermore, can by this taper (wedge-shaped design) of the line chamber with this Cable ends (wires) of different diameters are equipped. at different diameters, the taper causes a guide of the cable end in the direction that the cable end occupies such a position in which it reliably from the cutting terminal can be penetrated.

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 further development of the invention, the cable receiving part has a clamping sleeve. These Clamping sleeve can either after insertion of the cable end in the cable receiving part be used or even at the introduction of the cable end in the line chamber be inserted and penetrated by the cable end. After the cable end in the conduit chamber has been introduced, the clamping sleeve is in particular by machine set and thus fixes the position of the cable end with respect to the cable receiving part. Alternatively, even before the cable end is used, the clamping wedges as Designed barbs that hold after inserting the cable end of this. Already in this assembly step can be taken to ensure that that piece of Cable end, which is located in the line chamber, under a certain mechanical preload is available. This increases the effectiveness of the Contacting, since in addition to this bias nor the mechanical bias in addition, which arises when contacting with the insulation displacement terminal. In addition causes the fixing of the cable end by means of the clamping sleeve that the cable end during Contact with the insulation displacement terminal does not move out of the conduction chamber can be. Instead of a clamping sleeve, it is of course also conceivable that Detach cable detachable or unsolvable in the conduit chamber, being the last piece the cable remains freely movable in the conduit chamber. Regarding a permanent one Fixing can be thought of, the cable in the top of the Glue the line chamber. However, the use of a clamping sleeve has the advantage that this can be both machine used as well as 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 development of the invention, the insulation displacement terminal in a IDC receiving means arranged and the IDC receiving means connectable to the cable receiving part. Thus, as previously described, the cable end be inserted and fixed in the cable receiving part, wherein then the Cutting terminal by feeding the cutting terminal receiving means in the lower Area of the line chamber penetrates and causes the contact there. In conclusion Both the cable receiving part and the cutting terminal receiving means are connected to each other connected (eg by clipping, screwing, welding, gluing or The like), so that the finished cable connector is formed. The insulation displacement terminal points on its side facing away from the contact area connecting means such as pins, Contact sockets or the like on. These can be exposed or concentric be surrounded by a part of the insulation displacement receiving means.

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 Cross-section on. By this configuration of the cross section of the conduit chamber is ensures that the cable end on the one hand enough space for slightly curved On the other hand, however, a centering takes place, the ensures that when contacting the insulation displacement terminal, the cable end is not so can back down that no contact arises.

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 development of the invention, the center lines of the insulation displacement terminal and the Line chamber aligned, arranged parallel or inclined to each other. By the almost axial or ideally axial penetration of the insulation of the cable end arises between the insulation displacement terminal and the conductive core of the cable end a large-area, 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 based on the Figures explained.

FIG. 1:
a cable connector in longitudinal section and
FIG. 2:
the cable connector in cross section.

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 Cable end 3 can be introduced. For this purpose, in the cable receiving part 2 a conduit chamber 4 is present whose cross-section (in particular diameter) slightly larger than the diameter of the cable end 3. At the bottom of the Cable receiving parts 2, an opening 5 (slot) is provided by the one to descriptive cutting clamp can be introduced into the line chamber 4. in the upper portion of the cable receiving part 2 is a clamping sleeve 6 is present, the one Has in the axial direction (Z direction) extending clamping wedge 7. The clamping wedge has such an extent and extent that it is the remaining space of the Cross-section of the conduit chamber 4, which is not filled by the cable end 3, at least partially and in addition sufficient pressure on the Can exert cable end 3.

Der Zusammenbau des in Figur 1 gezeigten Kabelsteckverbinders 1 erfolgt wie folgt:

  • 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 assembly of the cable connector 1 shown in Figure 1 is as follows:
  • The cable end 3 is threaded through in the Z direction by the clamping sleeve 6 and inserted into the line chamber 4 of the cable receiving part 2. The clamping sleeve 6 is then also merged with the upper collar of the cable receiving part 2 and locked so that the clamping wedge 7 prevents retraction of the cable end 3. The wedge-shaped taper of the conduit chamber 4 in the Z direction causes the tip of the cable end 3 assumes a defined position with respect to a cutting terminal or the corresponding cut to length cable end 3 at least once in the X direction buckling, ie, that the cable end 3 is a slightly curved or also assumes an S-shaped configuration. Through the slot-like opening 5 arranged in a cutting terminal receiving means 8 cutting terminal 9 is inserted into the equipped with the cable end 3 line chamber 4. Due to the axial force applied via the insulation displacement terminal 9, the free cable end 3 is initially pushed back and its kinking initiated or reinforced until complete engagement of the kinked areas of the cable end 3 takes place on the walls of the conduit chamber 4. In this state, the neutral fiber of the core of the cable end 3 is then deformed so that it intersects the center line of the cutting clamp 9 at least once arcuately. As soon as due to the clamping force of the clamping sleeve 6 and additionally due to the friction of the insulation of the cable end 3 on the walls of the line chamber, the free ends of the wires can not retreat further, the penetration of the insulation and the electrical contact with the insulation displacement terminal 9 takes place. Then it must still be ensured that the cable receiving part 2 with the insulation displacement terminal 8 are permanently and detachably connected or unsolvable. The insulation displacement device 8 may be, for example, a part of the cable connector; but it is also conceivable that the insulation displacement terminal 9 is arranged on a circuit board of an electronic circuit or protrudes from a module, in which case the insulation displacement receiving means 8 would be the board or the housing of the module. The axial center line of the conduit chamber 4 may also be inclined obliquely to the Z or Y axis.

    • 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 Figur is the diamond-shaped cross-section of the conduit chamber 4 to recognize, with the Dimensions d and D, d. h., The extension of the diamond-shaped line chamber 4 in the X or Y direction, are different from each other. In any case, make sure that one of the both parameters d and D or both parameters are slightly larger than the Diameter of the cable end 3, so that it is arcuate in the line chamber 4 deform during insertion. A particularly advantageous case is given when the conduction chamber 4 has the rhombic shape and the equation d equals D. is satisfied. As a result, particularly space-saving implementations are possible. Of course, it can also be thought that the conduit chamber 4 in Cross section a round, an oval, a square, a rectangular or has such a cross-section, which is a combination of said geometric Represents cross sections.
