Description

Die Erfindung betrifft ein konfektioniertes geschirmtes Kabel, welches insbesondere einen Steckverbinder umfasst, zur Übertragung von HF-Signalen gemäß dem Anspruch 1. Weiterhin umfasst die Erfindung eine Vorrichtung zum Herstellen bzw. Konfektionieren eines derartigen Kabels gemäß dem Anspruch 9.The invention relates to a prefabricated shielded cable, which in particular comprises a connector, for the transmission of RF signals according to claim 1. Furthermore, the invention comprises an apparatus for producing or assembling such a cable according to claim 9.

Die betreffenden Kabel sind etwa in Kraftfahrzeugen oder Luftfahrzeugen einsetzbar und werden meist in großen Stückzahlen benötigt. Zur kostengünstigen Bereitstellung entsprechender Kabel sind ein einfacher Aufbau und eine einfache Konfektionierbarkeit von großer Bedeutung. Hinzu kommt, dass solche Kabel elektromagnetisch gut geschirmt sein müssen, damit keine abgestrahlten elektromagnetischen Wellen beispielsweise in der Bordelektronik des betreffenden Fahrzeugs Störungen verursachen können. Weiterhin müssen derartige Kabel so hergestellt sein, dass mit diesen Signale mit sehr hoher Frequenz übertragen werden können, wie dies zum Beispiel für eine qualitativ hochwertige Videosignalübertragung erforderlich ist.The cables in question are used for example in motor vehicles or aircraft and are usually needed in large quantities. For cost-effective provision of appropriate cables a simple structure and ease of assembly are of great importance. In addition, such cables must be electromagnetically well shielded so that no radiated electromagnetic waves, for example, in the on-board electronics of the vehicle in question can cause interference. Furthermore, such cables must be made so that they can be transmitted with these signals with very high frequency, as required for example for a high-quality video signal transmission.

Aus der DE 10 2007 047 436 A1 ist ein Kabel bekannt, welches eine geschirmte Bauweise aufweist. Dabei ist eine Crimpverbindung so ausgestaltet, dass diese eine so genannte Mittenaussparung aufweist.From the DE 10 2007 047 436 A1 a cable is known which has a shielded construction. In this case, a crimp connection is designed such that it has a so-called center recess.

In der EP 0 328 234 A2 ist ein geschirmtes Kabel gezeigt, welches eine Crimpverbindung zwischen einer Hülse und einem Schirm aufweist, die für eine hohe elektromagnetische Abschirmung geeignet sein soll.In the EP 0 328 234 A2 there is shown a shielded cable having a crimped connection between a sleeve and a screen to be suitable for high electromagnetic shielding.

Der Erfindung liegt die Aufgabe zugrunde, ein Kabel zu schaffen, welches überaus gut abgeschirmt ist, so dass die abgestrahlte elektromagnetische Leistung miniert ist, bzw. eine hohe EMV-Dichtigkeit gewährleistet ist. Weiterhin soll das Kabel dennoch mit vergleichsweise geringem Herstellungsaufwand fertigbar sein. Außerdem soll eine Crimpvorrichtung geschaffen werden, durch die derartige Kabel herstellbar sind.The invention has for its object to provide a cable which is very well shielded, so that the radiated electromagnetic power is miniert, or a high EMC-tightness is ensured. Furthermore, the cable should still be manufacturable with comparatively low production costs. In addition, a crimping device is to be created, can be produced by such cables.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 bzw. des Anspruchs 9 gelöst.This object is achieved by the features of claim 1 and of claim 9.

Erfindungsgemäß umfasst das Kabel zur Übertragung von HF-Signalen einen Schirm, zumindest eine Ader und eine elektrisch leitende Hülse. Die Hülse weist ihrerseits eine Längsachse auf und ist geometrisch betrachtet durch eine Längsschnittebene in eine erste geometrische Hülsenhälfte und eine zweite geometrische Hülsenhälfte unterteilbar. Weiterhin weist die Hülse einen ersten Abschnitt und einen zweiten Abschnitt auf, wobei die Abschnitte in Richtung der Längsachse zueinander versetzt angeordnet sind. Die Hülse umschließt zudem den Schirm und ist mit dem Schirm durch eine Crimpung verbunden. Die Crimpung ist derart ausgebildet, dass die Hülse innerhalb des ersten Abschnitts in der ersten Hülsenhälfte zumindest einen Crimpgrat aufweist und in der zweiten Hülsenhälfte crimpgratfrei ausgestaltet ist. Gleichzeitig ist die Hülse innerhalb des zweiten Abschnitts in der ersten Hülsenhälfte crimpgratfrei ausgestaltet ist und weist in der zweiten Hülsenhälfte zumindest einen Crimpgrat auf.According to the invention, the cable for transmitting RF signals comprises a screen, at least one core and an electrically conductive sleeve. The sleeve in turn has a longitudinal axis and, viewed geometrically, can be subdivided by a longitudinal sectional plane into a first geometric sleeve half and a second geometric sleeve half. Furthermore, the sleeve has a first portion and a second portion, wherein the portions are arranged offset from one another in the direction of the longitudinal axis. The sleeve also encloses the screen and is connected to the screen by crimping. The crimping is designed in such a way that the sleeve has at least one crimp ridge within the first section in the first sleeve half and is configured crimp-free in the second sleeve half. At the same time, the sleeve within the second section in the first sleeve half is crimped-free and has at least one crimping ridge in the second half of the sleeve.

Unter einer abschnittsweisen crimpgratfreien Gestalt einer Hülsenhälfte ist insbesondere zu verstehen, dass die Hülsenhälfte in dem betreffenden axialen Abschnitt innenseitig durchgehend konkav ausgestaltet ist, so dass dort eine gleichmäßige weitgehend ohne geometrische Störungen verlaufende Verpressung des Schirms erfolgt. Alleine das Vorhandensein von Pressmarken auf der Außenseite der Hülse kann daher nicht begründen, dass der betreffende Bereich der Hülse als crimpgratfrei zu sehen sei.A sectionally crimped-free shape of a sleeve half is to be understood in particular as meaning that the sleeve half in the relevant axial section is designed to be concave on the inside, so that there is a uniform pressing of the screen substantially without geometric disturbances. Alone the presence of press marks on the outside of the sleeve therefore can not justify that the relevant area of the sleeve should be seen as crimp-free.

Unter HF-Signalen sind im folgenden Signale zu verstehen, die mit Hilfe von Hochfrequenz-Technik erzeugt wurden, also beispielsweise auch UHF- oder VHF-Signale. Insbesondere zählen hierzu auch digitale Signale mit einer Übertragungsrate größer gleich 10 MBit/s.In the following, RF signals are to be understood as signals which have been generated with the aid of high-frequency technology, that is also, for example, UHF or VHF signals. In particular, this includes digital signals with a transmission rate greater than or equal to 10 Mbit / s.

Mit Vorteil weist die Hülse einen dritten Abschnitt auf, der gegenüber dem ersten und zweiten Abschnitt in Richtung der Längsachse versetzt angeordnet ist. Dabei weist die Hülse innerhalb des dritten Abschnitts in der ersten Hülsenhälfte zumindest einen Crimpgrat auf und ist in der zweiten Hülsenhälfte crimpgratfrei ausgestaltet.Advantageously, the sleeve has a third section, which is offset from the first and second sections in the direction of the longitudinal axis. In this case, the sleeve has at least one crimping ridge within the third section in the first sleeve half and is configured crimp-free in the second half-sleeve.

Aus rein geometrischer Sicht kann das erfindungsgemäße Kabel auch so charakterisiert werden, dass die Hülse innerhalb eines ersten Querschnitts in der ersten Hülsenhälfte zumindest einen Crimpgrat aufweist und in der zweiten Hülsenhälfte crimpgratfrei ausgestaltet ist und die Hülse innerhalb eines zweiten Querschnitts in der ersten Hülsenhälfte crimpgratfrei ausgestaltet ist und in der zweiten Hülsenhälfte zumindest einen Crimpgrat aufweist. Die Querschnitte sind orthogonal zur Längsachse orientiert und in Richtung der Längsachse zueinander versetzt angeordnet. Für den Fall, dass ein dritter Abschnitt vorliegt, kann auch dieser als ein dritter Querschnitt angesehen werden.From a purely geometrical point of view, the cable according to the invention can also be characterized in such a way that the sleeve has at least one crimping ridge within a first cross section in the first half of the sleeve and crimp-free in the second half of the sleeve and the sleeve is crimp-free within a second cross-section in the first half of the sleeve and in the second sleeve half has at least one Crimpgrat. The cross sections are oriented orthogonally to the longitudinal axis and offset from one another in the direction of the longitudinal axis. In the case of a third section, this too can be considered as a third section.

Die axiale Ausdehnung eines Abschnitts ergibt sich aus der Länge der Crimpgrate, so dass ein Abschnitt so lange ist wie sein längster Crimpgrat. Üblicherweise sind alle Crimpgrate in einem Abschnitt gleich lang. Die Abschnitte grenzen mit Vorteil unmittelbar aneinander, so dass über den gesamten Crimpbereich hinweg stets ein Crimpgrat in einer der Hülsenhälften vorliegt.The axial extent of a section results from the length of the crimp burrs, so that a section is as long as its longest crimp ridge. Usually, all crimp burrs in a section are the same length. Advantageously, the sections immediately adjoin one another so that there is always a crimp ridge in one of the sleeve halves over the entire crimp area.

In weiterer Ausgestaltung der Erfindung weist die Hülse im zweiten Abschnitt einen kleineren Durchmesser auf als im ersten Abschnitt. Sofern die Hülse auch einen dritten Abschnitt aufweist, kann der zweite Abschnitt den kleinsten Durchmesser im Vergleich zum ersten und dritten Abschnitt aufweisen. Der zweite Abschnitt mit dem kleinsten Durchmesser kann in Richtung der Längsachse zwischen dem ersten und dritten Abschnitt angeordnet sein.In a further embodiment of the invention, the sleeve in the second section has a smaller diameter than in the first section. If the sleeve also has a third section, the second section may have the smallest diameter compared to the first and third sections. The second section with the smallest diameter may be arranged in the direction of the longitudinal axis between the first and third sections.

Mit Vorteil ist die Hülse zumindest innerhalb der Abschnitte, also im Bereich der Crimpung, über ihren Umfang geschlossen ausgeführt, das heißt ohne eine Öffnung oder Schlitz. Folglich umschließt dann die Hülse den Schirm in radialer Richtung vollständig.Advantageously, the sleeve is executed at least within the sections, ie in the region of the crimp, closed over its circumference, that is without an opening or slot. Consequently, then the sleeve encloses the screen in the radial direction completely.

In vorteilhafter Bauweise weist der zumindest eine Crimpgrat im ersten Abschnitt eine größere axiale Ausdehnung auf als der zumindest eine Crimpgrat im zweiten Abschnitt.In an advantageous construction, the at least one crimp ridge in the first section has a greater axial extent than the at least one crimp ridge in the second section.

Mit Vorteil sind die Crimpgrate in einem Zentriwinkel um die Längsachse voneinander beabstandet, der kleiner als 150°, insbesondere kleiner als 135°, ist. Unter Zentriwinkel ist im Folgenden insbesondere ein Mittelpunktswinkel um einen Punkt auf der Längsachse innerhalb des jeweiligen Abschnitts zu verstehen, in dem sich die betreffenden Crimpgrate befinden.Advantageously, the crimp burrs are spaced apart from each other in a central angle about the longitudinal axis, which is smaller than 150 °, in particular smaller than 135 °. In the following, centering angle is to be understood as meaning, in particular, a midpoint angle about a point on the longitudinal axis within the respective section in which the respective crimp burrs are located.

Weiterhin kann die Außenseite der crimpgratfreien Hülsenhälfte im zweiten Abschnitt durchgehend konvex ausgestaltet sein. Alternativ oder ergänzend kann die Außenseite der crimpgratfreien Hülsenhälfte im ersten Abschnitt durchgehend konvex ausgestaltet sein. Insbesondere können die crimpgratfreien Hülsenhälften über einen Zentriwinkel von mindestens 180°außen rund ausgestaltet sein.Furthermore, the outer side of the crimp-free sleeve half in the second section can be made continuously convex. Alternatively or additionally, the outside of the crimp-free sleeve half in the first section can be made continuous convex. In particular, the crimp-free sleeve halves can be designed to be round outside over a central angle of at least 180 °.

In weiterer Ausgestaltung der Erfindung weist das Kabel vier Adern, die miteinander verdrillt sind, auf. Insbesondere kann das Kabel nach einem SternVierer-Konzept aufgebaut sein.In a further embodiment of the invention, the cable has four wires that are twisted together on. In particular, the cable can be constructed according to a SternVierer concept.

Vorteilhafterweise weist das Kabel im ersten Abschnitt als auch im zweiten Abschnitt eine elektrisch leitende Stützschelle auf, wobei der Schirm sowohl radial innen als auch radial außen an der Stützschelle anliegt. Dieses beidseitige Anliegen kann durch Umschlagen des Schirms vor dem Crimpen erreicht werden. Der Schirm kann als ein Schirmgeflecht aus einer Vielzahl von Einzeldrähten bestehen, so dass die Einzeldrähte sowohl radial innen als auch radial außen an der Stützschelle anliegen bzw. mit der Stützschelle verpresst sind. Die crimpgratfreien Hülsenhälften sind insbesondere so ausgestaltet, dass diese eine Innenkontur aufweisen, die im Wesentlichen parallel zur Außenkontur der Stützschelle verlaufen.Advantageously, the cable in the first section and in the second section on an electrically conductive support bracket, wherein the screen rests both radially inwardly and radially outwardly of the support bracket. This two-sided concern can be achieved by folding the screen before crimping. The screen may consist of a plurality of individual wires as a braided screen, so that the individual wires abut both radially inwardly and radially outwardly on the support bracket or with the support bracket are pressed. The crimp-free sleeve halves are in particular designed such that they have an inner contour that run essentially parallel to the outer contour of the support bracket.

Die Erfindung umfasst auch eine Crimpvorrichtung zur Herstellung eines Kabels, welches einen Schirm, zumindest eine bezüglich des Schirms radial innen liegende Ader und eine elektrisch leitende Hülse mit einer Längsachse aufweist, wobei die Hülse den Schirm umschließt und mit dem Schirm durch eine Crimpung verbunden ist. Die Crimpvorrichtung umfasst zwei Crimpstempel. Jeder der zwei Crimpstempel weist einen Crimper als auch einen Amboss auf. Der Crimper und der Amboss bei jedem der zwei Crimpstempel sind bezüglich der Längsachse versetzt zueinander angeordnet. Zur Crimpung der Hülse sind die beiden Crimpstempel derart zueinander angeordnet, dass diese so ineinandergreifen, dass jeweils ein Crimper mit einem Amboss zusammenwirkt, wenn die Crimpstempel zur Längsachse der Hülse hin relativ zueinander verfahren werden.The invention also includes a crimping apparatus for making a cable having a screen, at least one wire radially inward of the screen, and an electrically conductive sleeve having a longitudinal axis, the sleeve enclosing the screen and connected to the screen by crimping. The crimping device comprises two crimping dies. Each of the two crimping dies has a crimper as well as an anvil. The crimper and the anvil in each of the two crimping dies are offset with respect to the longitudinal axis. For crimping the sleeve, the two crimping dies are arranged relative to one another in such a way that they mesh with one another such that in each case a crimper interacts with an anvil when the crimping dies are moved relative to one another with respect to the longitudinal axis of the sleeve.

Die Crimpvorrichtung kann so ausgestaltet sein, dass zumindest einer der Crimpstempel einen für eine plastische Verformung der Hülse bestimmten Sattel aufweist, dessen Kontur gemäß einer Teilkreislinie verläuft. Als Teilkreislinie ist ein Line entlang eines Teilkreises zu verstehen, also entlang einer offenen (nicht geschlossenen) Kreislinie, die sich über einen Winkel von weniger als 360° erstreckt.The crimping device can be designed such that at least one of the crimping dies has a saddle intended for a plastic deformation of the sleeve, the contour of which runs along a partial circle line. A partial circle line is to be understood as a line along a partial circle, that is to say along an open (not closed) circular line which extends over an angle of less than 360 °.

Im einfachsten Fall umfasst ein Crimpstempel genau einen Crimper und einen Amboss. Die Crimpvorrichtung kann aus zwei baugleichen Crimpstempeln aufgebaut sein, wobei der erste Crimpstempel bezüglich eines Punktes auf der Längsachse der Hülse punktsymmetrisch zu dem anderen Crimpstempel angeordnet werden kann. Die zwei baugleichen Crimpstempeln können also zueinander um ihre Hochachse gedreht in der Crimpvorrichtung eingesetzt werden. Weiterhin können sämtliche Crimper der Crimpvorrichtung und / oder sämtliche Ambosse der Crimpvorrichtung baugleich ausgestaltet sein.In the simplest case, a crimping stamp comprises exactly one crimper and one anvil. The crimping device may be constructed from two identical Crimpstempeln, wherein the first crimping can be arranged with respect to a point on the longitudinal axis of the sleeve point symmetrical to the other crimping die. The two identical Crimpstempeln can thus be used to each other rotated about its vertical axis in the crimping device. Furthermore, all crimpers of the crimping device and / or all anvils of the crimping device can be of identical construction.

Mit Vorteil umfasst die Crimpvorrichtung zwei Crimpstempel, wobei einer der Crimpstempel zwei Crimper und einen Amboss aufweist. Alternativ oder ergänzend kann einer der Crimpstempel einen Crimper und zwei Ambosse aufweisen. Dabei sind jeweils Crimper und Amboss eines Crimpstempels bezüglich der Längsachse versetzt zueinander angeordnet und können zum Zwecke der Crimpung bzw. Verpressung der Hülse ineinander greifen.Advantageously, the crimping device comprises two crimping dies, wherein one of the crimping dies has two crimpers and one anvil. Alternatively or additionally, one of the crimping dies can have a crimper and two anvils. In each case, the crimper and anvil of a crimping die are offset relative to one another with respect to the longitudinal axis and can engage in one another for the purpose of crimping or pressing the sleeve.

In weiterer Ausgestaltung der Erfindung ist einer der Crimpstempel so ausgestaltet dass zwischen zwei Crimpern ein Amboss angeordnet ist oder zwischen zwei Ambossen ein Crimper. Mit Vorteil weist die Crimpvorrichtung einen Crimpstempel auf, bei dem zwischen zwei Crimpern ein Amboss angeordnet ist und einen Crimpstempel, bei dem zwischen zwei Ambossen ein Crimper angeordnet ist. Die Reihenfolge Crimper - Amboss entlang der Längsachse ist derart ausgestaltet, dass jeweils ein Crimper mit einem Amboss zusammenwirken kann.In a further embodiment of the invention, one of the crimping dies is designed such that an anvil is arranged between two crimps or a crimper between two anvils. Advantageously, the crimping device has a crimping die, in which an anvil is arranged between two crimping tools and a crimping punch, in which a crimper is arranged between two anvils. The order crimper - anvil along the longitudinal axis is designed such that in each case a crimper can interact with an anvil.

Die Crimpvorrichtung kann so konfiguriert sein, dass zumindest ein Crimpstempel derart ausgestaltet ist, dass Amboss und Crimper unterschiedliche Bauteile bzw. unterschiedliche Crimpeinsätze darstellen, welche insbesondere lösbar zueinander zusammengefügt sind. Mit Vorteil können dann zumindest einer der Ambosse oder Crimper einen für eine plastische Verformung der Hülse bestimmten Sattel aufweisen, dessen Kontur über der gesamten Dicke des Bauteils parallel zur Längsachse verläuft. Die unterschiedlichen Bauteile können unterschiedliche Dicken aufweisen.The crimping device can be configured such that at least one crimping die is designed such that the anvil and crimper represent different components or different crimping inserts, which in particular are releasably joined together. Advantageously, at least one of the anvils or crimpers can then have a saddle intended for a plastic deformation of the sleeve, the contour of which extends over the entire thickness of the component parallel to the longitudinal axis. The different components may have different thicknesses.

Alle Bauteile der Crimpvorrichtung, welche als Ambosse dienen, können jeweils mit der gleichen Kontur des Sattels ausgeführt sein. Ebenso können alle Bauteile der Crimpvorrichtung, welche als Crimper dienen, jeweils mit der gleichen Kontur des Sattels ausgeführt sein.All components of the crimping device, which serve as anvils, can each be designed with the same contour of the saddle. Likewise, all components of the crimping device, which serve as a crimper, each be designed with the same contour of the saddle.

Durch die Erfindung ist es möglich die Leitfähigkeit der Crimpverbindung zu erhöhen bzw. den Übergangswiderstand zu reduzieren, was eine bessere Schirmwirkung zur Folge hat. Die erfindungsgemäßen Kabel sind daher unempfindlich gegenüber äußeren elektromagnetischen Strahlungen und emittieren auch praktisch keine derartige Strahlung. Weiterhin kann bei der Herstellung des erfindungsgemäßen Kabels die Crimphöhe sehr fein eingestellt werden, so dass mit hoher Reproduzierbarkeit qualitativ hochwertige Kabel erzeugt werden können.The invention makes it possible to increase the conductivity of the crimp connection or to reduce the contact resistance, which results in a better shielding effect. The cables according to the invention are therefore insensitive to external electromagnetic radiation and also emit virtually no such radiation. Furthermore, in the production the cable according to the invention, the crimp height can be set very fine, so that high quality cables can be produced with high reproducibility.

Zudem weist die Crimpverbindung zwischen Hülse und Schirm eine überaus hohe Zugbelastbarkeit auf.In addition, the crimp connection between the sleeve and the shield has an extremely high tensile strength.

Vorteilhafte Ausbildungen der Erfindung entnimmt man den abhängigen Ansprüchen.Advantageous embodiments of the invention will remove the dependent claims.

Weitere Einzelheiten und Vorteile des erfindungsgemäßen Kabels ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der beiliegenden Figuren.Further details and advantages of the cable according to the invention will become apparent from the following description of an embodiment with reference to the accompanying figures.

In der Figur 1 ist eine einstückige elektrisch leitende Hülse 7 gezeigt, die mit Hilfe eines Tiefziehprozesses gefertigt wurde und ein Kupplungsende 7.7 umfasst, das zur Herstellung einer Steckverbindung mit einem weiteren Kupplungsteil geeignet ist. Die Hülse 7 ist insbesondere in demjenigen Bereich, welcher für die spätere Crimpung vorgesehen ist, im Wesentlichen hohlzylindrisch ausgestaltet. Der Hülse 7 kann eine Längsachse L, die in erster Näherung eine Symmetrieachse darstellt, zugeordnet werden. Im Übrigen ist die Hülse 7 zumindest in ihrem hohlzylindrischen rohrförmigen Bereich geschlossen, weist also keinen über die gesamte Länge der Hülse 7 verlaufenden Schlitz auf. An der Hülse 7 ist durch Umspritzung ein Passstück 8 aus Kunststoff angeordnet. Durch in den Figuren nicht näher dargestellte Aufnahmedornen wird ein formschlüssiger lagerichtiger Sitz zwischen dem Passstück 8 und der Hülse 7 erreicht.In the FIG. 1 a one-piece electrically conductive sleeve 7 is shown, which was manufactured by means of a deep drawing process and comprises a coupling end 7.7, which is suitable for producing a plug connection with a further coupling part. The sleeve 7 is designed in particular in the region which is provided for the subsequent crimping, substantially hollow cylindrical. The sleeve 7 can be associated with a longitudinal axis L, which in the first approximation represents an axis of symmetry. Incidentally, the sleeve 7 is closed at least in its hollow cylindrical tubular portion, so has no running over the entire length of the sleeve 7 slot. On the sleeve 7 a fitting 8 made of plastic is arranged by encapsulation. By receiving mandrels not shown in the figures, a form-fitting positionally correct seat between the fitting 8 and the sleeve 7 is achieved.

In den Figuren 2a und 2b ist ein erstes Crimpeinsatzpaar 10 gezeigt, welches aus einem Crimper 11 und einem Amboss 12 besteht. Der Crimper 11 und der Amboss 12 weisen jeweils einen Sattel 11.1, 12. 1 auf, der für die plastische Verformung der Hülse 7 bestimmt ist. Die Sattel 11.1, 12. 1 haben im vorgestellten Ausführungsbeispiel jeweils eine Kontur, die gemäß einer Teilkreislinie verläuft. Der Radius R der Kontur bzw. der Teilkreislinie ist im Bereich des Sattels 11.1, 12. 1 für den Crimper 11 und den Amboss 12 gleich groß bemessen. Der Crimper 11 umfasst zudem zwei Wangen 11.2, 11.3, welche einander gegenüberliegend angeordnet sind und als Einlauffläche für die zu crimpende Hülse 7 dienen. Wie aus der Figur 2a ersichtlich, weist also der Crimper 11 als Summe der Länge der Kontur des Sattels 11.1 und der Wangen 11.2, 11.3 eine längere konkave Kontur auf als der Amboss 12, bei dem als konkave Kontur im Wesentlichen nur die Kontur des Sattels 12. 1 vorliegt. Im gezeigten Ausführungsbeispiel haben der Crimper 11 und der Amboss 12 des ersten Crimpeinsatzpaars 10 eine Dicke D von 2 mm.In the FIGS. 2a and 2b a first crimping insert 10 is shown which consists of a crimp 11 and an anvil 12. The crimper 11 and the anvil 12 each have a saddle 11.1, 12. 1, which is intended for the plastic deformation of the sleeve 7. The saddle 11.1, 12. 1 in the illustrated embodiment each have a contour which extends in accordance with a partial circle line. The radius R of the contour or the partial circle line is dimensioned equal in the region of the saddle 11.1, 12.1 for the crimper 11 and the anvil 12. The crimper 11 also includes two cheeks 11.2, 11.3, which are arranged opposite one another and serve as an inlet surface for the sleeve to be crimped 7. Like from the FIG. 2a As can be seen, therefore, the crimp 11 as the sum of the length of the contour of the saddle 11.1 and the cheeks 11.2, 11.3 a longer concave contour than the anvil 12, in which as a concave contour substantially only the contour of the saddle is 12.1. In the illustrated embodiment, the crimper 11 and the anvil 12 of the first crimping pair 10 have a thickness D of 2 mm.

In den Figuren 3a und 3b ist ein zweites Crimpeinsatzpaar 20 dargestellt. Dieses umfasst ebenfalls einen Crimper 21 und einen Amboss 22 mit jeweils einem Sattel 21.1, 22. 1. Der Radius r der Kontur ist jeweils im Bereich des Sattels 21.1, 22. 1 für den Crimper 21 und den Amboss 22 gleich groß dimensioniert. Das Crimpeinsatzpaar 20 unterscheidet sich vom Crimpeinsatzpaar 10 nach Figur 2 unter anderem dadurch, dass der Radius r geringfügig kleiner ist als der entsprechende Radius R beim Crimpeinsatzpaar 10 gemäß der Figur 2a. Im Unterschied zum Crimpeinsatzpaar 10 gemäß der Figur 2b haben der Crimper 21 und der Amboss 22 gemäß der Figur 3b nur eine Dicke d von 1 mm. Der Crimper 21 weist als Summe der Länge der Kontur des Sattels 21.1 und der Wangen 21.2, 21.3 eine längere konkave Kontur auf als der Amboss 22, bei dem als konkave Kontur im Wesentlichen nur die Kontur des Sattels 22. 1 vorliegt.In the FIGS. 3a and 3b a second crimping insert pair 20 is shown. This also includes a crimper 21 and an anvil 22, respectively a saddle 21.1, 22. 1. The radius r of the contour is dimensioned equal in size in the region of the saddle 21.1, 22. 1 for the crimper 21 and the anvil 22. The crimping insert pair 20 differs from the crimping insert pair 10 FIG. 2 inter alia in that the radius r is slightly smaller than the corresponding radius R in the crimping pair 10 according to the FIG. 2a , In contrast to the Crimpeinsatzpaar 10 according to the FIG. 2b have the crimper 21 and the anvil 22 according to the FIG. 3b only a thickness d of 1 mm. The crimper 21, as the sum of the length of the contour of the saddle 21.1 and the cheeks 21.2, 21.3, has a longer concave contour than the anvil 22, in which only the contour of the saddle 22.1 exists as a concave contour.

Weiterhin wird im vorgestellten Ausführungsbeispiel ein drittes Crimpeinsatzpaar 30 (Figur 4b) verwendet, welches auch einen Crimper 31 und einen Amboss 32 umfasst. Die beiden Crimpeinsatzpaare 10, 30 sind im vorgestellten Ausführungsbeispiel baugleich hergestellt. Demgemäß entspricht die Geometrie des Crimpeinsatzes 31 derjenigen des Crimpeinsatzes 11 nach den Figuren 2a, 2b und die Geometrie des Crimpeinsatzes 32 derjenigen des Crimpeinsatzes 12 nach den Figuren 2a, 2b.Furthermore, in the presented embodiment, a third crimping insert pair 30 (FIG. FIG. 4b ), which also includes a crimp 31 and an anvil 32. The two Crimpeinsatzpaare 10, 30 are made identical in the illustrated embodiment. Accordingly, the geometry of the crimping insert 31 corresponds to that of the crimping insert 11 according to FIGS FIGS. 2a, 2b and the geometry of the crimping insert 32 of that of the crimping insert 12 after FIGS. 2a, 2b ,

Die für die plastische Verformung der Hülse 7 bestimmten Sattel 11.1, 12.1, 21.1, 22.1 der sechs Crimpeinsätze 11, 12, 21, 22, 31, 32 weisen über deren gesamten Dicke D, d eine Kontur auf, die parallel zur Längsachse L verläuft. Entsprechend haben die Crimper 11, 21, 31 sowie die Ambosse 12, 22, 32 im Bereich der Sattel 11.1, 12.1, 21.1, 22.1 in Richtung der Längsachse L kein Profil.The specific for the plastic deformation of the sleeve 7 saddle 11.1, 12.1, 21.1, 22.1 of the six crimping inserts 11, 12, 21, 22, 31, 32 have over the entire thickness D, d a contour which is parallel to the longitudinal axis L. Accordingly, the crimpers 11, 21, 31 and the anvils 12, 22, 32 in the saddle 11.1, 12.1, 21.1, 22.1 in the direction of the longitudinal axis L no profile.

Die drei Crimpeinsatzpaare 10, 20, 30 werden nun gemäß den Figuren 4a und 4b zu Crimpstempeln 100, 200 sandwichartig zusammengefügt, so dass die Crimper 11, 21, 31 und die Ambosse 12, 22, 32 bezüglich der Längsachse L versetzt zueinander angeordnet sind. Der erste Crimpstempel 100 umfasst die Crimper 11 und 31 sowie den Amboss 22. Dabei ist beim ersten Crimpstempel 100 der Amboss 22 zwischen den zwei Crimpern 11, 31 angeordnet. Dem zweiten Crimpstempel 200 sind die Ambosse 12, 32 zugeordnet und der Crimper 21. Der Crimper 21 liegt beim Crimpstempel 200 zwischen den zwei Ambossen 12, 32.The three crimping pairs 10, 20, 30 will now be according to the FIGS. 4a and 4b into crimp punches 100, 200, so that the crimps 11, 21, 31 and the anvils 12, 22, 32 are offset relative to one another with respect to the longitudinal axis L. The first crimping die 100 comprises the crimps 11 and 31 as well as the anvil 22. In the case of the first crimping die 100, the anvil 22 is arranged between the two crimping 11, 31. The second crimping die 200 is associated with the anvils 12, 32 and the crimper 21. The crimper 21 is located at the crimping die 200 between the two anvils 12, 32nd

Mit Hilfe der in den Figuren 4a und 4b gezeigten Crimpstempel 100, 200 soll ein Kabel gemäß den Figuren 5 bis 8 hergestellt werden. Das Kabel weist zentral einen Füller 1 aus isolierendem Material auf, um den herum vier Adern 2, welche jeweils von einer Isolierung 3 umgeben sind, gedreht angeordnet sind. Radial außerhalb bezüglich der Adern 2 mit den Isolierungen 3 befindet sich ein Schirm 4, hier in Form eines Schirmgeflechts. Der Schirm 4 wird über die überwiegende Kabellänge von einem isolierenden Mantel 6 umschlossen (Figur 5). Derartige Kabel werden häufig als Sternvierer bezeichnet. Die vier Adern 2 mit ihren Isolierungen 3 sind miteinander verdrillt, wodurch eine hohe Übersprechdämpfung erreichbar ist.With the help of in the FIGS. 4a and 4b shown crimper 100, 200 is a cable according to the FIGS. 5 to 8 getting produced. The cable has centrally a filler 1 of insulating material around which four cores 2, which are each surrounded by an insulation 3, are arranged rotated. Radially outside with respect to the wires 2 with the insulation 3 is a screen 4, here in the form of a shield braid. The screen 4 is enclosed by the predominant cable length of an insulating jacket 6 ( FIG. 5 ). Such cables are often referred to as a star quad. The four wires 2 with their insulation 3 are twisted together, whereby a high crosstalk attenuation can be achieved.

Im Zuge der Konfektionierung des Kabels wird zunächst in einem Endbereich einer elektrischen Leitung der isolierende Mantel 6 entfernt, so dass in diesem Endbereich der Schirm 4 freigelegt ist. Als nächstes wird dann um den Schirm 4 eine elektrisch leitfähige Stützschelle 5, die einen Schlitz 5.1 aufweist (Figur 6) gepresst und der Schirm 4 um die Stützschelle 5 herum umgeschlagen bzw. umgestülpt. Auf den umgeschlagenen Schirm 4 wird sodann die Hülse 7 gemäß der Figur 1 geschoben. Eine derartige Hülse 7 kann auch als Außenleiterhülse bezeichnet werden. Der Außendurchmesser der Hülse 7 ist in dem Bereich, wo eine Crimpung durchgeführt werden soll etwas größer als der doppelte Radius R, r der Sattel 11.1, 12.1, 21.1, 22.1.In the course of assembling the cable, the insulating jacket 6 is first removed in an end region of an electrical line so that the shield 4 is exposed in this end region. Next, an electrically conductive support clip 5, which has a slot 5.1 (FIG. FIG. 6 Pressed and the screen 4 is folded around the support bracket 5 around or everted. On the folded screen 4 is then the sleeve 7 according to the FIG. 1 pushed. Such a sleeve 7 may also be referred to as outer conductor sleeve. The outer diameter of the sleeve 7 is in the region where a crimping to be performed slightly larger than twice the radius R, r of the saddle 11.1, 12.1, 21.1, 22.1.

Durch einen Crimpprozess wird darauffolgend ein elektrischer und mechanischer Verbund zwischen der Hülse 7 und dem Schirm 4 erzeugt. Zu diesem Zweck wird die am Kabel befindliche Hülse 7 zwischen die Crimpstempel 100, 200 gelegt. Der in der Figur 4b dargestellte Crimpstempel 100 wird nun zum zweiten Crimpstempel 200 hin bewegt, bis der hohlzylindrische Teil der Hülse 7 gegen den Schirm 4 in gewünschtem Maße verpresst ist.By a crimping process, an electrical and mechanical bond between the sleeve 7 and the screen 4 is subsequently produced. For this purpose, the sleeve 7 located on the cable is placed between the crimping dies 100, 200. The Indian FIG. 4b illustrated crimping punch 100 is now moved toward the second crimping die 200 until the hollow cylindrical portion of the sleeve 7 is pressed against the screen 4 to the desired extent.

Das so erzeugte Kabel weist im Bereich der Hülse 7 drei, bezogen auf die Richtung der Längsachse L der Hülse 7, axial versetzt angeordnete umlaufende Abschnitte I, II, III auf. Die axiale Ausdehnung jedes der Abschnitte I, II, III ergibt sich aus der Dicke D, d der Crimper 11, 21, 31 bzw. der Ambosse 12, 22, 32 (siehe Figuren 7 und 8). Im vorgestellten Ausführungsbeispiel weisen demnach die Abschnitte I und III eine axiale Ausdehnung von 2 mm auf, während der mittlere Abschnitt II eine axiale Ausdehnung von 1 mm hat. Die Abschnitte I, II, III können also geometrisch als virtuelle Scheiben aufgefasst werden mit den Dicken D bzw. d und Stirnseiten, die orthogonal zur Längsachse L orientiert sind.In the region of the sleeve 7, the cable thus produced has three circumferential sections I, II, III, which are axially offset relative to the direction of the longitudinal axis L of the sleeve 7. The axial extent of each of the sections I, II, III results from the thickness D, d of the crimpers 11, 21, 31 and the anvils 12, 22, 32 (see FIGS. 7 and 8 ). In the exemplary embodiment presented, therefore, the sections I and III have an axial extent of 2 mm, while the middle section II has an axial extent of 1 mm. The sections I, II, III can thus be interpreted geometrically as virtual slices with the thicknesses D and d and end faces, which are oriented orthogonal to the longitudinal axis L.

Die Hülse 7 kann geometrisch in zwei Hülsenhälften 7a, 7b unterteilt werden, wobei eine Längsschnittebene M, die hier bezüglich der Hülse 7 mittig zu liegen kommt, die beiden Hülsenhälften 7a, 7b geometrisch trennt. Die Hülsenhälften 7a, 7b haben also in etwa die Form von Rohrhalbschalen. Entsprechend liegt, geometrisch betrachtet, die Längsachse L auf der Längsschnittebene M, so dass folglich die Längsschnittebene M gleichzeitig die Zeichenebene der Figur 7 und der Figur 8 ist.The sleeve 7 can be geometrically subdivided into two sleeve halves 7a, 7b, wherein a longitudinal section plane M, which in this case comes to lie centrally with respect to the sleeve 7, geometrically separates the two sleeve halves 7a, 7b. The sleeve halves 7a, 7b thus have approximately the shape of pipe shells. Correspondingly, viewed geometrically, the longitudinal axis L lies on the longitudinal section plane M, so that consequently the longitudinal section plane M at the same time the plane of the drawing FIG. 7 and the FIG. 8 is.

Im konfektionierten Kabel umschließt die Hülse 7 den Schirm 4, so dass der Schirm 4 sowohl an der radial innen liegenden Seite der Stützschelle 5 als auch an der radial außen liegenden Seite der Stützschelle 5 an der Stützschelle 5 anliegt.In the ready-made cable, the sleeve 7 encloses the shield 4, so that the shield 4 bears against the support clamp 5 both on the radially inner side of the support clamp 5 and on the radially outer side of the support clamp 5.

Aufgrund des etwas kleineren Radius r der Sattel 22.1, 22.2 des zweiten Crimpeinsatzpaars 20 entsteht eine Einschnürung im zweiten Abschnitt 11, bzw. weist die gecrimpte Hülse 7 im zweiten Abschnitt II einen geringeren Durchmesser auf.Due to the slightly smaller radius r of the saddle 22.1, 22.2 of the second Crimpeinsatzpaars 20 creates a constriction in the second section 11, or has the crimped sleeve 7 in the second section II a smaller diameter.

Durch die Crimpung sind in der Hülse 7 Crimpgrate 7.1 bis 7.6 entstanden, so dass die Hülse 7 innerhalb des ersten und dritten axialen Abschnitts I, III in der ersten Hülsenhälfte 7a je zwei Crimpgrate 7.1, 7.2; 7.5, 7.6 aufweist. In der zweiten Hülsenhälfte 7b ist die Hülse 7 im ersten und dritten axialen Abschnitt I, III crimpgratfrei ausgestaltet, also innenseitig durchgehend konkav, so dass dort eine gleichmäßige weitgehend ohne geometrische Störungen verlaufende Verpressung des Schirms erfolgte. Fernerhin ist die Hülse 7 innerhalb des zweiten axialen Abschnitts II in der ersten Hülsenhälfte 7a crimpgratfrei ausgestaltet und weist in der zweiten Hülsenhälfte 7b zwei Crimpgrate 7.3, 7.4 auf. Im gezeigten Ausführungsbeispiel sind die Crimpgrate 7.1, 7.2 im ersten Abschnitt I, die Crimpgrate 7.3, 7.4 im zweiten Abschnitt II und die Crimpgrate 7.5, 7.6 im dritten Abschnitt III jeweils in einem Zentriwinkel β um die Längsachse L voneinander beabstandet. Der betreffende Zentriwinkel β beträgt hier 120°. Als Zentriwinkel ist der Mittelpunktswinkel um einen Punkt auf der Längsachse L innerhalb des betreffenden Abschnittes I, II, III zu verstehen. Als maßgeblicher Zentriwinkel kommt selbstredend der kürzeste Abstand in Betracht und nicht etwa der komplementäre Winkel (hier 240°) bezüglich des 360°-Umfangs. Die Hülsenhälfte 7a ist an ihrer Außenseite im zweiten Abschnitt II durchgehend konvex ausgestaltet und weist dort den Radius r auf, während die Hülsenhälfte 7b im ersten Abschnitt I und im dritten Abschnitt III an ihrer Außenseite durchgehend konvex ausgestaltet ist und in diesen Abschnitten I, III den Radius R hat. Durch die spezielle Ausgestaltung der Crimpung wird eine hervorragende elektrische Verbindung zwischen dem Schirm 4 und der Hülse 7 erreicht. Zudem ist auch eine erhöhte mechanische Zugbelastbarkeit festzustellen.Crimping has produced crimp burrs 7.1 to 7.6 in the sleeve 7, so that the sleeve 7 within the first and third axial sections I, III in the first sleeve half 7a each have two crimp burrs 7.1, 7.2; 7.5, 7.6. In the second sleeve half 7b, the sleeve 7 in the first and third axial section I, III crimpgratfrei configured, ie on the inside continuously concave, so that there was a uniform running largely without geometric disturbances pressing the screen. Furthermore, the sleeve 7 is configured crimp-free within the second axial section II in the first sleeve half 7a and has two in the second half-sleeve 7b Crimp burrs 7.3, 7.4 up. In the exemplary embodiment shown, the crimp burrs 7.1, 7.2 in the first section I, the crimp burrs 7.3, 7.4 in the second section II and the crimp burrs 7.5, 7.6 in the third section III are each spaced apart from each other at a central angle β about the longitudinal axis L. The relevant central angle β is 120 ° here. The central angle is to be understood as the midpoint angle about a point on the longitudinal axis L within the relevant section I, II, III. Of course, the most important central angle is the shortest distance and not the complementary angle (in this case 240 °) with respect to the 360 ° circumference. The sleeve half 7a is continuously convex on its outer side in the second section II and has there the radius r, while the sleeve half 7b in the first section I and in the third section III on its outside is designed to be continuously convex and in these sections I, III the Radius R has. Due to the special design of the crimp an excellent electrical connection between the screen 4 and the sleeve 7 is achieved. In addition, an increased mechanical tensile strength is observed.

Das so ausgestaltete Kabel dient etwa in Fahrzeugen zur Übertragung von HF-Signalen (Hochfrequenz-Signalen). Insbesondere kann das Kabel zur Herstellung einen so genannten FAKRA-Steckverbindung (FAKRA: Fachkreis-Automobil) verwendet werden, wobei das Passstück 8 gemäß den Figuren 1 und 5 zur positionsrichtigen Befestigung einer Sekundärverriegelung dient. Bedingt durch die hohen Datenübertragungsraten, z. B. 480 Mbit/s, treten im Kabel hohe Spannungs-Frequenzen, in der Größenordnung von beispielsweise 40 MHz auf. Es hat sich nun gezeigt, dass ein entsprechendes Kabel in herkömmlicher Bauweise im Betrieb relativ hohe Abstrahlpegel verursacht. Insbesondere können die hohen Abstrahlpegel in der Bordelektronik eines Fahrzeugs Störungen auslösen, was insbesondere bei sicherheitsrelevanten Funktionen der Bordelektronik unter allen Umständen vermieden werden muss. Durch die nun entwickelte Bauweise des Kabels wird eine überaus gute EMV-Dichtigkeit erreicht, so dass Abstrahlpegel des Kabels im Bereich des Steckverbinders, bzw. der Hülse 7 stark reduziert sind.The cable designed in this way is used, for example, in vehicles for the transmission of RF signals (high-frequency signals). In particular, the cable for producing a so-called FAKRA connector (FAKRA: Fachkreis-Automobil) can be used, wherein the fitting 8 according to the FIGS. 1 and 5 serves for the positionally correct attachment of a secondary locking. Due to the high data transfer rates, z. B. 480 Mbit / s, occur in the cable high voltage frequencies, on the order of 40 MHz, for example. It has now been found that a corresponding cable in conventional construction in operation causes relatively high emission levels. In particular, the high emission levels in the on-board electronics of a vehicle can cause disturbances, which must be avoided under all circumstances, especially in the case of safety-relevant functions of the on-board electronics. Due to the design of the cable, which has now been developed, an extremely good EMC-tightness is achieved, so that radiation levels of the cable in the area of the connector or of the sleeve 7 are greatly reduced.
