Ein solches elektrisches Kabel umfasst eine innere Leiteranordnung mit einem oder mehreren längserstreckten elektrischen Leitern sowie eine (isolierende) äußere Hülle, die die innere Leiteranordnung umschließt, und einen elektrischen Schirm des Kabels, der die Leiteranordnung im Querschnitt ringförmig umgibt und der, in radialer Richtung - d.h. senkrecht zur Erstreckungsrichtung der inneren Leiteranordnung - betrachtet, zwischen der inneren Leiteranordnung und der äußeren Hülle des Kabels verläuft. Die einzelnen elektrischen Leitung(en) der inneren Leiteranordnung sind dabei vorteilhaft jeweils mit einem elektrisch isolierenden Mantel versehen, um einen elektrischen Kontakt zwischen den einzelnen Leitern der inneren-Leiteranordnung untereinander sowie mit dem elektrischen Schirm des Kabels zu vermeiden.Such an electrical cable comprises an inner conductor arrangement having one or more elongated electrical conductors and an (insulating) outer sheath which encloses the inner conductor arrangement, and an electrical shield of the cable, which surrounds the conductor arrangement in cross-section annularly and which, in the radial direction. ie perpendicular to the direction of extension of the inner conductor arrangement - viewed between the inner conductor arrangement and the outer sheath of the cable. The individual electrical line (s) of the inner conductor arrangement are advantageously provided in each case with an electrically insulating jacket in order to avoid electrical contact between the individual conductors of the inner conductor arrangement with each other and with the electrical shield of the cable.

Bei derartig geschirmten elektrischen Kabeln ist es bekannt, den elektrischen Schirm an einem Endabschnitt des Kabels, an dem beispielsweise ein elektrischer Steckverbinder vorzusehen ist, so nach außen umzulegen bzw. umzuschlagen, dass sich ein außen liegender Teilbereich des Schirmes auf der (der inneren Leiteranordnung abgewandten) Außenseite der äußeren Hülle des Kabels erstreckt, so dass er entlang der radialen Richtung von dem zwischen der inneren Leiteranordnung und der äußeren Hülle verlaufenden Hauptbereich des elektrischen Schirmes beabstandet ist. Die äußere Hülle des Kabels kann dabei in demjenigen Endabschnitt, in dem der elektrische Schirm des Kabels nach außen umgelegt ist, eine Stützhülse aufweisen, entlang der sich ein Teil des nach außen umgelegten Teilbereiches des Schirmes erstreckt und an die sich in axialer Richtung, also in Erstreckungsrichtung der Leiteranordnung, ein üblicher, aus einem weichelastischen bzw. flexiblen Material bestehender isolierender Mantel der äußeren Hülle des Kabels anschließt.In such shielded electrical cables, it is known, the electric screen at one end portion of the cable, on which, for example, an electrical connector is to be provided to flip out or turn over that an outer portion of the screen on the (the inner conductor assembly facing away ) Extends outside the outer sheath of the cable so as to be spaced along the radial direction from the main portion of the electric screen extending between the inner conductor assembly and the outer sheath. The outer sheath of the cable can in this end portion, in which the electrical shield of the cable is folded outwards, have a support sleeve, along which a part of the outwardly folded portion of the screen extends and to which in the axial direction, ie in Extension direction of the conductor arrangement, a conventional, consisting of a soft elastic or flexible material insulating jacket of the outer sheath of the cable connects.

Dabei kann zur Fixierung der Anordnung auf denjenigen Endabschnitt der äußeren Hülle des Kabels, auf dem der nach außen umgelegte Teilbereich des elektrischen Schirmes des Kabels verläuft, eine Fixierhülse, z. B. in Form einer Crimphülse aufgebracht sein, die den außen liegenden Teilbereich des elektrischen Schirmes umschließt und an der Außenseite der Hülle des Kabels hält. Ein derartiges elektrisches Kabel ist beispielsweise in der EP 0 694 989 A2 beschrieben.It can be used to fix the arrangement on those end portion of the outer shell of the cable, on which extends the outwardly folded portion of the electric screen of the cable, a fixing sleeve, for. B. in the form of a crimp sleeve, which encloses the outer portion of the electric screen and holds on the outside of the shell of the cable. Such an electrical cable is for example in the EP 0 694 989 A2 described.

EP 1246300 offenbart ein elektriches Kabel gemäβ dem Oberbegriff des Anspruchs 1, dem entsprechenden Verfahren aus Anspruch 6 und einer Vorrichtung zum Hersteller des Kabels. EP 1246300 discloses an electrical cable according to the preamble of claim 1, the corresponding method of claim 6 and a device to the manufacturer of the cable.

Besteht der elektrische Schirm des Kabels in bekannter Weise aus einem Geflecht einer Vielzahl Einzellitzen, so kann es nach dem Umlegen eines Teilbereiches des elektrischen Schirmes nach außen, so dass dieser Teilbereich als ein äußerer Bereich des Schirmes an der Außenseite (äußeren Oberfläche) der äußeren Hülle des Kabels verläuft, zu einem undefinierten Aufstellen einzelner Litzen des Schirmes kommen, was weitere Verarbeitungsschritte, wie z. B. das Aufbringen einer äußeren Fixierhülse, erschwert und als Folge zu optischen Mängeln oder Funktionsstörungen führen kann. Ferner besteht unter dem Gesichtspunkt des Arbeitsschutzes eine Verletzungsgefahr an undefiniert aufgestellten Litzen eines Schirmgeflechtes.If the electric shield of the cable is made of a mesh of a plurality of individual strands in a known manner, it may turn outwards after a portion of the electric shield has been folded over, so that this portion acts as an outer portion of the shield on the outside (outer surface) of the outer shell the cable runs, come to an undefined setting up individual strands of the screen, resulting in further processing steps, such. As the application of an outer fixing sleeve, difficult and can lead to optical defects or malfunction as a result. Furthermore, there is a risk of injury to undefined laid strands of a braided shield from the point of view of occupational safety.

Der Erfindung liegt das Problem zugrunde, ein elektrisches Kabel der eingangs genannten Art zu schaffen, dass sich durch eine definierte Positionierung eines nach außen umgelegten Teilbereiches des elektrischen Schirmes des Kabels auszeichnet. Weiterhin sollen ein Verfahren und eine Vorrichtung angegeben werden, um ein solches verbessertes elektrisches Kabel herzustellen.The invention is based on the problem to provide an electrical cable of the type mentioned that is characterized by a defined positioning of an outwardly folded portion of the electric screen of the cable. Furthermore, a method and an apparatus are to be specified in order to produce such an improved electrical cable.

Dieses Problem wird hinsichtlich des elektrischen Kabels durch die Merkmale des Patentanspruchs 1 gelöst.This problem is solved with respect to the electric cable by the features of claim 1.

Danach ist der nach außen umgelegte Teilbereich des elektrischen Schirmes des Kabels derart in die äußere Hülle des Kabels eingearbeitet, dass der nach außen umgelegte Teilbereich des elektrischen Schirmes zumindest abschnittsweise in der äußeren Hülle des elektrischen Kabels verläuft (dabei aber von dem innen liegenden Hauptbereich des elektrischen Schirmes möglichst in radialer Richtung beabstandet ist).Thereafter, the outwardly folded portion of the electric screen of the cable is incorporated in such a way in the outer shell of the cable that the outwardly folded portion of the electric screen extends at least partially in the outer shell of the electric cable (However, it is spaced as far as possible from the inner main region of the electric screen in the radial direction).

Dadurch kann eine definierte Positionierung des nach außen umgelegten Teilbereiches des elektrischen Schirmes des Kabels an der äußeren Hülle jenes Kabels erreicht werden, so dass etwa bei einem als Geflecht ausgebildeten elektrischen Schirm keine undefiniert nach außen abstehenden Einzellitzen des Schirmes vorliegen.Thereby, a defined positioning of the outwardly folded portion of the electric screen of the cable to the outer shell of that cable can be achieved, so that there are no undefined outwardly projecting individual strands of the screen in a braided electrical screen.

Hierzu kann insbesondere vorgesehen sein, dass der elektrische Schirm des Kabels unter Druck in einen zuvor durch Erhitzen angeschmolzenen Abschnitt der äußeren Hülle des Kabels eingedrückt worden ist. Mit anderen Worten wird die äußere Hülle des Kabels in einem Abschnitt durch Erhitzen in einen (viskosen) Zustand überführt, der ein Eindrücken des nach außen umgelegten Teilbereiches des elektrischen Schirmes des Kabels in jenen Abschnitt der Hülle gestattet.For this purpose, it can be provided, in particular, that the electrical screen of the cable has been pressed under pressure into a section of the outer sheath of the cable, which has previously been melted by heating. In other words, the outer sheath of the cable in a section is brought into a (viscous) state by heating, which allows the outwardly folded portion of the electrical shield of the cable to be pushed into that section of the sheath.

Weist die äußere Hülle des Kabels neben einem durch Erhitzen in einen (viskosen) Schmelzzustand überführbaren Mantel eine sich hieran in axialer Richtung anschließende Stützhülse auf, die zum Abstützen des nach außen umgelegten Teilbereiches des elektrischen Schirmes dient, so erstreckt sich der nach außen umgelegte Teilbereich des elektrischen Schirmes in axialer Richtung, d. h. entlang der Erstreckungsrichtung des elektrischen Kabels, vorteilhaft so weit, dass er über jene Stützhülse hinaus bis zum elastischen Mantel der äußeren Hülle reicht, in die der äußere Teilbereich des elektrischen Schirmes bevorzugt einzuarbeiten ist.If, in addition to a jacket which can be converted into a (viscous) melt state by heating, the outer sheath of the cable has a support sleeve adjoining thereon in the axial direction, which serves to support the portion of the electric screen folded outwards, then the outwardly directed portion of the sheath extends electric screen in the axial direction, d. H. along the direction of extension of the electric cable, advantageously so far that it extends beyond that support sleeve to the elastic sheath of the outer sheath into which the outer portion of the electric shield is preferably to be incorporated.

Nach außen hin kann der (End-)Abschnitt des elektrischen Kabels, der mit dem nach außen umgelegten und in die äußere Hülle des Kabels eingearbeiteten Teilbereich des elektrischen Schirmes versehen ist, wiederum von einer Fixierhülse, z. B. in Form einer Crimphülse, umschlossen sein.Outwardly, the (end) portion of the electrical cable, which is provided with the folded-out and incorporated into the outer shell of the cable portion of the electric screen, in turn, by a fixing sleeve, for. B. in the form of a crimp sleeve, be enclosed.

Ein Verfahren zur Herstellung eines elektrischen Leiters mit einem definiert positionierten nach außen umgelegten Teilbereich des elektrischen Schirmes ist durch die Merkmale des Patentanspruchs 6 charakterisiert.A method for producing an electrical conductor with a defined positioned outwardly folded portion of the electric screen is characterized by the features of claim 6.

Danach ist insbesondere vorgesehen, den nach außen umgelegten Teilbereich des elektrischen Schirmes des Kabels zumindest abschnittsweise in die äußere Hülle des Kabels einzuarbeiten, und zwar bevorzugt durch Eindrücken, nachdem die äußere Hülle des Kabels durch Erhitzen in einen (viskosen) Schmelzzustand gebracht worden ist.Thereafter, provision is made, in particular, to incorporate the portion of the electric shield of the cable which has been turned outwards at least in sections into the outer sheath of the cable, preferably by pressing in, after the outer sheath of the cable has been brought into a (viscous) melted state by heating.

Vorteilhafte Ausgestaltungen des Verfahrens sind in den von Patentanspruch 6 abhängigen Ansprüchen angegeben.Advantageous embodiments of the method are specified in the dependent of claim 6 claims.

Eine Vorrichtung zur Durchführung des vorgenannten Verfahrens, um ein elektrisches Kabel herzustellen, bei dem ein nach außen umgelegter Teilbereich des elektrischen Schirmes in die äußere Hülle des Kabels eingearbeitet ist, umfasst eines oder mehrere verfahrbare Werkzeuge, die in einer ersten Position eine Öffnung bilden, in die ein mit einem nach außen umgelegten Teilbereich des elektrischen Schirmes versehener (End-) Abschnitt des elektrischen Kabels einführbar ist, und die nach dem Einführen des besagten (End-)Abschnittes des Kabels in eine zweite Position verfahrbar sind, in der sie den nach außen umgelegten Teilbereich des elektrischen Schirmes des Kabels in den äußeren Mantel des Kabels hineindrücken.An apparatus for carrying out the aforementioned method for producing an electrical cable, in which an outwardly folded portion of the electric screen is incorporated in the outer sheath of the cable, comprises one or more movable tools, which form an opening in a first position a (end) portion of the electric cable provided with an outwardly folded portion of the electric screen is insertable, and after insertion of said (end) portion of the cable are movable to a second position in which they outwardly Push folded portion of the electrical shield of the cable in the outer jacket of the cable.

Konkret können das verfahrbare Werkzeug bzw. die verfahrbaren Werkzeuge in einer ersten Position eine Öffnung mit einem ersten Querschnitt definieren, in die der mit dem nach außen umgelegten Teilbereich des elektrischen Schirmes versehene (End-) Abschnitt des Kabels einführbar ist, und nach dem Verfahren in die zweite Position eine Öffnung mit einem zweiten, kleineren Querschnitt bilden, nämlich einem Querschnitt, der kleiner ist als der Querschnitt des Kabels gemessen bis zur Außenseite der äußeren Hülle des Kabels, so dass bei dem Überführen des Werkzeugs bzw. der Werkzeuge aus der ersten in die zweite Position der nach außen umgelegte Teilbereich des elektrischen Schirmes in die äußere Hülle des Kabels gedrückt wird.Concretely, in a first position, the movable tool or tools can define an aperture having a first cross-section into which the (end) portion of the cable provided with the portion of the electric screen folded outwards can be inserted and according to the method of FIG the second position forming an opening with a second, smaller cross section, namely a cross section which is smaller than the cross section of the cable measured to the outside of the outer sheath of the cable, so that in the transfer of the tool or tools from the first in the second position of the outward folded portion of the electric screen is pressed into the outer shell of the cable.

Der zweite Querschnitt der Öffnung sollte dabei gleichzeitig größer sein als der Querschnitt des von der Innenseite der äußeren Hülle des Kabels umschlossenen Raumes, so dass der nach außen umgelegte Teilbereich des elektrischen Schirmes des Kabels nicht bis in den von der äußeren Hülle umschlossenen Innenraum des Kabels hineingedrückt wird, sondern vielmehr in jener äußeren Hülle verläuft.The second cross section of the opening should at the same time be larger than the cross section of the space enclosed by the inside of the outer sheath of the cable, so that the outwardly folded portion of the electric screen of the cable is not pressed into the interior of the cable enclosed by the outer sheath but rather runs in that outer shell.

Weiterhin ist vorteilhaft eine Heizeinrichtung vorgesehen, mit der die äu-βere Hülle des Kabels an demjenigen (End-)Abschnitt erhitzt und in einen (viskosen) Schmelzzustand überführt wird, in den der nach außen umgelegte Teilbereich des elektrischen Schirmes einzuarbeiten ist.Furthermore, a heating device is advantageously provided, with which the outer shell of the cable is heated at that (end) section and converted into a (viscous) melt state into which the outwardly folded portion of the electric screen is to be incorporated.

Figuren 1 und 1A zeigt in schematischer Darstellung ein elektrisches Kabel mit einer (entlang einer Erstreckungsrichtung E) längserstreckten inneren Leiteranordnung 1, umfassend eine Mehrzahl längs erstreckter elektrischer Leiter 11, 12, 13, 14, die jeweils in bekannter Weise mit einem elektrisch isolierenden Mantel versehen sind, so dass die einzelnen Leiter 11, 12, 13, 14 der Leiteranordnung 1 elektrisch gegeneinander isoliert sind. Figures 1 and 1A shows a schematic representation of an electrical cable with an (along an extension direction E) elongated inner conductor assembly 1, comprising a plurality of longitudinally extending electrical conductors 11, 12, 13, 14, each provided in known manner with an electrically insulating jacket, so that the individual conductors 11, 12, 13, 14 of the conductor arrangement 1 are electrically insulated from one another.

Die innere Leiteranordnung 1 ist umgeben von einem elektrischen Schirm 2, gebildet durch ein Schirmgeflecht aus einer Vielzahl elektrisch leitender Litzen, welcher (mit einem Hauptbereich 20) die innere Leiteranordnung 1 im Querschnitt ringförmig umgibt. An den elektrischen Schirm 2 des Kabels bzw. genauer an dessen Hauptbereich 20 schließt sich nach außen hin eine (isolierende) äußere Hülle 3 an, die sowohl die innere Leiteranordnung 1 als auch den elektrischen Schirm 2 bzw. dessen Hauptbereich 20 umschließt. Somit erstreckt sich der elektrische Schirm 2 mit seinem Hauptbereich 20 zwischen der inneren Leiteranordnung 1 und der äußeren Hülle 3 des Kabels. Mit anderen Worten ausgedrückt, folgen bei dem elektrischen Kabel, in radialer Richtung R von innen nach außen, eine Leiteranordnung 1, ein Hauptbereich 20 eines elektrischen Schirmes 2 und eine äußere Hülle 3 aufeinander.The inner conductor arrangement 1 is surrounded by an electrical screen 2, formed by a screen braid of a plurality of electrically conductive strands, which (with a main area 20) the inner conductor arrangement 1 surrounds annularly in cross-section. To the electrical screen 2 of the cable or more precisely to the main region 20 connects to the outside an (insulating) outer shell 3, which encloses both the inner conductor assembly 1 and the electric screen 2 and its main region 20. Thus, the electrical screen 2 extends with its main portion 20 between the inner conductor assembly 1 and the outer shell 3 of the cable. In other words, follow in the electrical cable, in the radial direction R from the inside to the outside, a conductor assembly 1, a main portion 20 of an electric umbrella 2 and an outer shell 3 to each other.

Die äußere Hülle 3 des Kabels wird überwiegend gebildet durch einen (weich-) elastischen bzw. flexiblen Mantel 30 (z.B. bestehend aus PVC oder PUR), an den sich an einem axialen Endabschnitt des Kabels eine formstabile Stützhülse 35 anschließt, die beispielsweise als eine Crimphülse durch Crimpen auf die innere Leiteranordnung 1 aufgebracht sein kann.The outer sheath 3 of the cable is predominantly formed by a (soft) elastic or flexible sheath 30 (eg made of PVC or PUR), to which at an axial end portion of the cable a dimensionally stable support sleeve 35 connects, for example, as a crimp sleeve may be applied by crimping on the inner conductor assembly 1.

Ein in Figur 1A rechtseitig dargestellter Endabschnitt des Kabels ist mit einem Steckverbinder zu versehen, über den das elektrische Kabel an eine zugeordnete elektrische Baugruppe anschließbar ist. Hierzu sind dort die elektrischen Leiter 11, 12, 13, 14 der inneren Leiteranordnung 1 (jenseits der Stützhülse 35) von der äußeren Hülle 3 befreit, um eine elektrische Kontaktierung der Leiter 11, 12, 13, 14 mit hierfür vorgesehenen Steckerelementen eines Steckverbinders zu ermöglichen.An in Figure 1A right side end portion of the cable is to be provided with a connector, via which the electrical cable can be connected to an associated electrical assembly. For this purpose, there are the electrical conductors 11, 12, 13, 14 of the inner conductor assembly 1 (beyond the support sleeve 35) freed from the outer shell 3, to make electrical contact with the conductors 11, 12, 13, 14 with connector elements provided for this purpose of a connector enable.

Weiterhin ist an jedem Endabschnitt des Kabels ein Teilbereich 25 (Endbereich) des elektrischen Schirmes 2 des Kabels (um 180°) nach außen umgelegt bzw. umgeschlagen, so dass er sich - im Gegensatz zum Hauptbereich 20 des elektrischen Schirmes 2 - nicht mehr zwischen der inneren Leiteranordnung 1 und der äußeren Hülle 3 des Kabels erstreckt, sondern vielmehr auf der (der inneren Leiteranordnung 1 abgewandten) Außenseite 31 der äußeren Hülle 3. Dabei verläuft der außen liegende Teilbereich 25 des elektrischen Schirmes 2 mit einem ersten Abschnitt 25a an der Außenseite der Stützhülse 35 und mit einem sich daran anschließenden zweiten Abschnitt 25b an der Außenseite 31 des Mantels 30 der äußeren Hülle 3. Mit anderen Worten ausgedrückt, ist der elektrische Schirm 2 des Kabels, der mit einem Hauptbereich 20 zwischen der inneren Leiteranordnung 1 und der äußeren Hülle 3 des Kabels entlang dessen Erstreckungsrichtung E verläuft mit seinem einen Endbereich des Schirmes 2 bildenden Teilbereich 25 am rechtseitigen Endabschnitt des Kabels so nach außen umgelegt bzw. umgeschlagen, dass jener Teilbereich 25 entlang der Erstreckungsrichtung E des Kabels ein Stück weit zurück verläuft, und zwar über die Stützhülse 35 der äußeren Hülle 3 hinaus. Dabei umschließt der Schirm 2 die innere Leiteranordnung 1 im Querschnitt ringförmig. Somit erstreckt sich jener außen liegende Teilbereich 25 des elektrischen Schirmes 2 bis zu dem elastischen bzw. flexiblen isolierenden Mantel 30 der äußeren Hülle 3.Furthermore, at each end portion of the cable, a portion 25 (end portion) of the electric screen 2 of the cable (180 °) folded out or turned over, so that he - in contrast to the main area 20 of the electric screen 2 - no longer between the Inner conductor assembly 1 and the outer shell 3 of the cable extends, but rather on the (the inner conductor assembly 1 facing away) outside 31 of the outer shell 3. In this case, the outer portion 25 of the electric screen 2 extends with a first portion 25a on the outside the support sleeve 35 and with an adjoining second portion 25b on the outer side 31 of the jacket 30 of the outer shell 3. In other words, the electric screen 2 of the cable, with a main portion 20 between the inner conductor assembly 1 and the outer Shell 3 of the cable along its extension direction E extends with its one end portion of the screen 2 forming portion 25 at the right end portion of the cable so folded out or turned over that that portion 25 along the direction of extension E of the cable runs a bit back, and indeed beyond the support sleeve 35 of the outer shell 3 addition. In this case, the screen 2 surrounds the inner conductor arrangement 1 in cross-section annular. Thus, that outer portion 25 of the electric screen 2 extends to the elastic or flexible insulating jacket 30 of the outer shell. 3

Über jenem mit dem außen liegenden, umgeschlagenen Teilbereich 25 des elektrischen Schirmes 2 versehenen Endabschnitt des Kabels kann in üblicher Weise eine äußere Fixierhülse, z. B. in Form einer weiteren Crimphülse, angeordnet werden.About that with the outside, folded portion 25 of the electric screen 2 provided end portion of the cable can in the usual way an outer fixing, z. B. in the form of another crimping sleeve can be arranged.

Um zu verhindern, dass nach dem Umlegen bzw. Umschlagen eines Teilbereiches 25 des elektrischen Schirmes 2 einzelne Litzen des den elektrischen Schirm 2 bildenden Geflechtes undefiniert abstehen, ist vorgesehen, jenen außen liegenden Teilbereich 25 des elektrischen Schirmes 2 abschnittsweise so in die äußere Hülle 3, genauer in den elastischen bzw. flexiblen Mantel 30 der Hülle 3 einzuarbeiten, dass jener Teilbereich 25 des elektrischen Schirmes 2 abschnittsweise innerhalb jenes Mantels 30 verläuft. Insbesondere verlaufen die freien Ende 25b innerhalb des Mantels 30. Demnach erstrecken sich die einzelnen Litzen des den elektrischen Schirm 2 bildenden Geflechtes in der Wand des Mantels 30, wie in Figur 1 B in einem Querschnitt durch das elektrische Kabel schematisch dargestellt.In order to prevent the individual strands of the braiding 2 forming the electric screen 2 from protruding undetached after folding over or turning over a partial area 25 of the electric screen 2, it is provided that those outer partial area 25 of the electric screen 2 are partially inserted into the outer shell 3, more accurately incorporate into the elastic or flexible jacket 30 of the shell 3 that that portion 25 of the electric screen 2 sections within that shell 30 runs. In particular, the free ends 25b extend within the jacket 30. Accordingly, the individual strands of the braid forming the electrical shield 2 extend in the wall of the jacket 30, as in FIG Figure 1 B shown schematically in a cross section through the electrical cable.

Der umgelegte, außen liegende Teilbereich 25 des elektrischen Schirmes 2 bzw. genauer die das entsprechende Schirmgeflecht bildenden Litzen werden dabei nur soweit in den Mantel 30 der äußeren Hülle 3 eingearbeitet, dass der Teilbereich 25 des elektrischen Schirmes 2 möglichst nicht in den von der äußeren Hülle 3 umschlossenen Innenraum I des Kabels hineinragt, in dem ja der Hauptbereich 20 des elektrischen Schirmes 2 sowie weiterhin die innere Leiteranordnung 1 verlaufen. D. h., der in den Mantel 30 der äußeren Hülle 3 eingearbeitete Teilbereich 25 des elektrischen Schirmes 2 erstreckt sich innerhalb der ringförmig umlaufenden Wand des Mantels 30 nicht aber durch diese bzw. deren Innenseite 32 hindurch bis in den Innenraum I des Kabels, der von eben jenem Mantel 30 umschlossen ist. Dadurch ist der in den Mantel 30 der äußeren Hülle 3 eingearbeitete Teilbereich 25 des elektrischen Schirmes 2 insbesondere in radialer Richtung von dem innen liegenden Hauptbereich 20 des elektrischen Schirmes 2 beabstandet.The folded, outer portion 25 of the electric screen 2 or more precisely the corresponding braid forming strands are only so far incorporated into the shell 30 of the outer shell 3, that the portion 25 of the electric screen 2 as possible not in the outer shell 3 enclosed interior I of the cable protrudes, in which yes the main area 20 of the electric screen 2 and continue to run the inner conductor assembly 1. D. h., The incorporated in the shell 30 of the outer shell 3 portion 25 of the electric screen 2 extends within the annular peripheral wall of the shell 30 but not through this or the inside 32 through to the interior I of the cable, the is surrounded by just that jacket 30. As a result, the partial region 25 of the electric screen 2 incorporated in the casing 30 of the outer casing 3 is spaced, in particular in the radial direction, from the inner main region 20 of the electric screen 2.

Wie anhand einer Zusammenschau der Figuren 1A und 2A deutlich wird, umfasst das Werkzeug, mit dem der nach außen umgelegte Teilbereich 25 des elektrischen Schirmes 2 in die äußere Hülle 3 bzw. den Mantel 30 des Kabels einarbeitbar ist, zwei Werkzeugteile W1, W2, die entlang einer Verfahrrichtung V relativ zueinander verfahrbar sind (Figur 2A). Jedes der beiden Werkzeugteile W1, W2 weist an einer dem jeweils anderen Werkzeugteil W2, W1 zugewandten Stirnseite eine Aufnahme A1, A2 auf; und die beiden Aufnahmen A1, A2 bilden gemeinsam eine Öffnung O für das zu bearbeitende elektrische Kabel.As with a synopsis of Figures 1A and 2A becomes clear, comprises the tool with which the outwardly folded portion 25 of the electric screen 2 in the outer shell 3 and the jacket 30 of the cable is einarbeitbar, two tool parts W1, W2, which along a travel direction V relative to each other are movable ( FIG. 2A ). Each of the two tool parts W1, W2 has a receptacle A1, A2 on a front side facing the respective other tool part W2, W1; and the two recordings A1, A2 together form an opening O for the electrical cable to be processed.

In dem in Figur 2A gezeigten ersten Zustand, in dem die beiden Werkzeugteile W1, W2 eine erste Relativposition zueinander entlang der Verfahrrichtung V einnehmen, weist die durch die beiden Aufnahmebereiche A1, A2 gebildete Öffnung O einen so großen Querschnitt auf, dass das elektrische Kabel darin einführbar ist, bis dessen mit dem umgelegten Teilbereich 25 des elektrischen Schirmes 2 versehener Endabschnitt sich in jener Öffnung O zwischen den Aufnahmebereichen A1, A2 der beiden Werkzeuge W1, W2 befindet. Mit anderen Worten ausgedrückt, ist der Querschnitt der Öffnung O in dem ersten Zustand des Werkzeuges, in dem die Aufnahmebereiche A1, A2 der beiden Werkzeuge W1, W2 eine erste Relativposition zueinander entlang der Verfahrachse V aufweisen, größer als der mit dem nach außen umgelegten Teilbereich 25 des elektrischen Schirmes 2 versehenen Endabschnittes des elektrischen Kabels, vergleiche insbesondere Figur 1 A.In the in FIG. 2A In the first state in which the two tool parts W1, W2 assume a first relative position to one another along the travel direction V, the opening O formed by the two receiving regions A1, A2 has such a large cross-section that the electrical cable can be inserted therein until it End portion provided with the folded portion 25 of the electric screen 2 is located in that opening O between the receiving portions A1, A2 of the two tools W1, W2. In other words, that is Cross-section of the opening O in the first state of the tool, in which the receiving areas A1, A2 of the two tools W1, W2 have a first relative position to each other along the travel axis V, greater than the provided with the outwardly folded portion 25 of the electric screen 2 end portion of the electric cable, compare in particular Figure 1 A ,

Nach der Anordnung des mit dem nach außen umgelegten Teilbereich 25 des elektrischen Schirmes 2 versehenen Endabschnittes des Kabels in der Öffnung O zwischen den beiden Werkzeugteilen W1, W2 werden diese entlang der Verfahrrichtung V, die mit der Radialen R des zu bearbeitenden elektrischen Kabels zusammenfällt, aufeinander zu bewegt. Dabei nimmt der Querschnitt der zwischen den beiden Aufnahmebereichen A1, A2 gebildeten Öffnung O ab, vergleiche Figur 2B. Hierbei sammeln zunächst die durch Formbacken der Werkzeugteile W1, W2 gebildeten Aufnahmebereiche A1, A2 die Schirmlitzen am freien Ende 25b des elektrischen Schirmes 2 und positionieren diese parallel zur Außenseite 31 des Mantels 30. Bei einem weiteren Zusammenfahren der Werkzeugteile W1, W2 wird dann der an der Außenseite 31 der äußeren Hülle 3 bzw. des Mantels 30 verlaufende Teilbereich 25 des elektrischen Schirmes 2 in die Hülle 3 bzw. genauer den Mantel 30 eingearbeitet.After the arrangement of the outwardly folded portion 25 of the electric screen 2 provided end portion of the cable in the opening O between the two tool parts W1, W2 these along the direction of travel V, which coincides with the radial R of the electrical cable to be processed, to each other too moved. In this case, the cross section of the opening O formed between the two receiving areas A1, A2 decreases, cf. FIG. 2B , In this case, the receiving areas A1, A2 formed by forming jaws of the tool parts W1, W2 initially collect the shielding strands at the free end 25b of the electric screen 2 and position them parallel to the outside 31 of the mantle 30. In a further movement of the tool parts W1, W2 then the the outer side 31 of the outer shell 3 and the shell 30 extending portion 25 of the electric screen 2 in the shell 3 or more precisely the shell 30 incorporated.

Dies erfolgt jedoch nicht allein unter dem Druck der sich aufeinander zu bewegenden Werkzeugteile W1, W2, sondern ergänzend unter Überführung des von dem nach außen umgelegten Teilbereich 25 des elektrischen Schirmes 2 überdeckten Abschnittes des Mantels 30 in einen Schmelzzustand, in dem die Aufnahmebereiche A1, A2 der Werkzeugteile W1, W2 entsprechend erhitzt werden. Hierzu können an den Aufnahmebereichen A1, A2 entsprechende Heizdrähte oder sonstige Heizmittel vorgesehen sein, die z.B. elektrisch betreibbar sind.However, this does not take place solely under the pressure of the tool parts W1, W2 moving towards one another, but in addition to transferring the section of the jacket 30 covered by the outwardly folded partial region 25 of the electric screen 2 into a melt state in which the receiving regions A1, A2 the tool parts W1, W2 are heated accordingly. For this purpose, corresponding heating wires or other heating means may be provided at the receiving areas A1, A2, e.g. are electrically operated.

Nachdem der nach außen umgelegte Teilbereich 25 des elektrischen Schirmes 2 bzw. genauer dessen den Mantel 30 der äußeren Hülle 3 überdeckendes freies Ende 25b durch Zusammenfahren der Werkzeugteile W1, W2 in die in Figur 2B gezeigte zweite Relativposition unter gleichzeitiger Erwärmung des Mantels 30 in diesen hineingedrückt worden ist und der Mantel 30 sich anschließend wieder abgekühlt hat, wird das Werkzeug wieder geöffnet; d. h., die Werkzeugteile W1, W2 werden wieder in den in Figur 2A gezeigten ersten Zustand überführt. In diesem weisen die beiden Werkzeugteile W1, W2 einen solchen Abstand voneinander auf, dass das elektrische Kabel ohne weiteres aus dem Werkzeug entnommen werden kann.After the folded-out portion 25 of the electric screen 2 or more precisely the jacket 30 of the outer shell 3 covering free end 25b by moving together of the tool parts W1, W2 in the in FIG. 2B shown second relative position with simultaneous heating of the jacket 30 has been pressed into this and the jacket 30 has then cooled again, the tool is opened again; ie, the tool parts W1, W2 are again in the in FIG. 2A transferred shown first state. In this, the two tool parts W1, W2 at such a distance from each other that the electrical cable can be easily removed from the tool.

Das Kabel weist dann im Querschnitt in demjenigen Bereich seines Mantels 30, der von dem nach außen umgelegten Teilbereich 25 des elektrischen Schirmes 2 überdeckt war, die in Figur 1B gezeigte Konfiguration auf. D. h., in diesem Abschnitt des Mantels 30 verlaufen innerhalb der durch jenen Mantel 30 gebildeten Wand die einzelnen Litzen des Geflechtes, welche das freie Ende 25b des elektrischen Schirmes 2 bilden.The cable then has in cross-section in the region of its jacket 30, which was covered by the outwardly folded portion 25 of the electric screen 2, which in FIG. 1B shown configuration. D. h., In this section of the jacket 30 extend within the wall formed by those sheath 30, the individual strands of the braid, which form the free end 25 b of the electric screen 2.

Konkret bilden die Aufnahmebereiche A1, A2 der Werkzeugteile W1, W2 im vorliegenden Ausführungsbeispiel in ihrer zweiten Relativposition, wie in Figur 2B dargestellt, eine kreisförmige Öffnung O, deren Innendurchmesser kleiner ist als der Außendurchmesser des zu bearbeitenden elektrischen Kabels an der Außenseite 31 von dessen Mantel 30 und gleichzeitig größer ist als der Innendurchmesser des zu bearbeitenden elektrischen Kabels an der dem Innenraum I zugewandten Innenseite 32 des Mantels 30. Hierdurch werden die einzelnen Litzen des freien Endes 25b des elektrischen Schirmes 2 gemäß Figur 1 B in die Wand des viskosen, angeschmolzenen Mantels 30 eingebracht, ohne jedoch bis in das Innere I des Kabels überführt zu werden.Specifically, in the present embodiment, the receiving areas A1, A2 of the tool parts W1, W2 form in their second relative position, as in FIG FIG. 2B illustrated, a circular opening O, whose inner diameter is smaller than the outer diameter of the electrical cable to be processed on the outer side 31 of the jacket 30 and at the same time greater than the inner diameter of the electrical cable to be processed on the inner side facing the inner space 32 of the jacket 30th As a result, the individual strands of the free end 25b of the electric screen 2 according to Figure 1 B introduced into the wall of the viscous molten shell 30, but without being transferred to the interior I of the cable.

Das genaue Verhältnis zwischen dem Querschnitt (Innendurchmesser) der Öffnung O im zweiten, geschlossenen Zustand der Werkzeugteile W1, W2 und dem Außendurchmesser des Kabels an der Außenseite 31 von dessen Mantel 30 ist dabei im jeweiligen Einzelfall anhand der geometrischen Ausgestaltung des Kabels sowie anhand der verwendeten Materialien zu ermitteln. Typische Wandstärken des Mantels 30 liegen in der Größenordnung von 1 mm, z. B. bei 0.6 mm.The exact ratio between the cross section (inner diameter) of the opening O in the second, closed state of the tool parts W1, W2 and the outer diameter of the cable on the outer side 31 of the jacket 30 is in each case based on the geometric configuration of the cable and on the basis of the used To identify materials. Typical wall thicknesses of the shell 30 are of the order of 1 mm, z. B. at 0.6 mm.

Bevorzugt können die Aufnahmebereiche A1, A2 der Werkzeuge W1, W2 separat zueinander erhitzt werden, und zwar insbesondere unter Verwendung einer (thermisch) geregelten Heizeinrichtung. Die durch Erhitzen der Aufnahmebereiche A1, A2 in die Hülle 3 des zu bearbeitenden Kabels einzubringende Wärmemenge ist dabei so zu wählen, dass das Material des Mantels 30 angeschmolzen wird und hierdurch vorteilhaft in einen viskosen Zustand übergeht, der ein Eindrücken des freien Endes 25 des elektrischen Schirmes 2 in den Mantel 30 des Kabels ermöglicht. Hierzu ist neben der Temperatur auch die Heizdauer geeignet einzustellen.Preferably, the receiving areas A1, A2 of the tools W1, W2 can be heated separately from each other, in particular using a (thermally) controlled heating device. The amount of heat to be introduced by heating the receiving areas A1, A2 in the shell 3 of the cable to be processed is to be chosen so that the material of the shell 30 is melted and thereby advantageously merges into a viscous state, the pressing of the free end 25 of the electric Umbrella 2 in the jacket 30 of the cable allows. For this purpose, in addition to the temperature and the heating time to set suitable.

Dabei verbleiben die Werkzeugteile W1, W2 mit ihren Aufnahmebereichen A1, A2 während einer hinreichend langen Verweildauer in der in Figur 2B gezeigten geschlossenen Stellung, um nach dem Eindrücken des freien Endes 25b des elektrischen Schirmes 2 in den Mantel 30 des Kabels eine definierte Kreiskontur an der (angeschmolzenen) Außenseite 31 des Mantels 30 auszubilden und um den in den Mantel 30 eingedrückten Abschnitt 25b des elektrischen Schirmes 2 bzw. dessen einzelne Litzen innerhalb des Mantels 30 zu halten, bis der Mantel 30 hinreichend abgekühlt ist.In this case, the tool parts W1, W2 remain with their receiving areas A1, A2 during a sufficiently long residence time in the in FIG. 2B shown closed position to form after pressing the free end 25b of the electric screen 2 in the jacket 30 of the cable a defined circular contour on the (fused) outer side 31 of the shell 30 and the depressed into the shell 30 portion 25b of the electric screen. 2 or to keep its individual strands within the jacket 30 until the jacket 30 has cooled sufficiently.

In den Figuren 3A bis 3C ist eine Abwandlung der Anordnung aus Figur 2A in geöffnetem Zustand dargestellt, d. h. in das Werkzeug kann in dem in den Figuren 3A bis 3C gezeigten ersten Zustand ein zu bearbeitendes elektrisches Kabel eingebracht werden, und zwar insbesondere ein mit einem umgelegten, außen liegenden Teilbereich 25 des elektrischen Schirmes 2 versehener (End-)Abschnitt eines Kabels.In the FIGS. 3A to 3C is a modification of the arrangement FIG. 2A shown in the open state, ie in the tool can in the in the FIGS. 3A to 3C In the first state shown, an electrical cable to be processed is introduced, in particular a (end) section of a cable provided with a folded outer section 25 of the electric screen 2.

Im Unterschied zu der Anordnung aus Figur 2A weist das in den Figuren 3A bis 3C gezeigte Werkzeug drei zueinander verfahrbare Werkzeugteile W1, W2, W3 auf, die auf einem gemeinsamen Träger T beweglich (verfahrbar) gelagert sind. Wie im Fall der in Figur 2A dargestellten Anordnung weisen jedoch auch die Werkzeugteile W1, W2, W3 aus den Figuren 3A bis 3C jeweils einen Aufnahmebereich A1, A2 bzw. A3 auf, wobei die Aufnahmebereiche A1, A2, A3 im in den Figuren 3A bis 3C gezeigten geöffneten Zustand des Werkzeugs eine Öffnung O definieren, deren Querschnitt hinreichend groß ist, um einen mit einem umgelegten, außen liegenden Teilbereich 25 des elektrischen Schirmes 2 versehenen (End-)Abschnitt eines zu bearbeitenden Kabels in jene Öffnung O einführen zu können.Unlike the arrangement FIG. 2A has that in the FIGS. 3A to 3C Tool shown three mutually movable tool parts W1, W2, W3, which are mounted on a common carrier T movable (movable). As in the case of in FIG. 2A However, the arrangement shown also have the tool parts W1, W2, W3 from the FIGS. 3A to 3C each have a receiving area A1, A2 and A3, wherein the receiving areas A1, A2, A3 in the in the FIGS. 3A to 3C shown opened state of the tool defining an opening O, whose cross-section is sufficiently large, to be able to introduce a provided with a folded, outer portion 25 of the electric screen 2 (end) portion of a cable to be machined in that opening.

An jedes der Werkzeugteile W1, W2, W3 (in Form von Schiebern) ist au-βerdem eine elektrische Leitung L1, L2, L3 angeschlossen, um das jeweilige Werkzeugteil elektrischer Energie zum Betrieb einer Heizeinrichtung versorgen zu können, die ein Erhitzen des Aufnahmebereiches A1, A2, A3 des jeweiligen Werkzeugteiles W1, W2, W3 ermöglicht.To each of the tool parts W1, W2, W3 (in the form of slides), an electrical line L1, L2, L3 is also connected in order to be able to supply the respective tool part with electrical energy for operation of a heating device, which heats the receiving area A1, A2, A3 of the respective tool part W1, W2, W3 allows.

Gemäß dem Übergang von den Figuren 3A und 3B zu den Figuren 4A und 4B lassen sich die Werkzeugteile W1, W2, W3 entlang ihrer jeweiligen Verfahrrichtung V1, V2, V3 derart in einen zweiten, geschlossenen Zustand überführen, dass sie mit ihren Aufnahmebereichen A1, A2, A3 eine Öffnung O definieren, deren Innendurchmesser kleiner ist als der Außendurchmesser des Mantels 30 des hierin zu bearbeitenden Kabels, vergleiche Figur 1 A. Die Verfahrrichtungen V1, V2, V3 der Werkzeugteile W1, W2, W3 fallen dabei mit der radialen Richtung R eines bestimmungsgemäß in der Öffnung O des Werkzeugs angeordneten elektrischen Kabels zusammen.According to the transition from the FIGS. 3A and 3B to the FIGS. 4A and 4B the tool parts W1, W2, W3 can be moved along their respective travel direction V1, V2, V3 into a second, closed state in such a way that they define with their receiving regions A1, A2, A3 an opening O whose inner diameter is smaller than the outer diameter of the Sheath 30 of the cable to be processed herein, cf. Figure 1 A , The directions of movement V1, V2, V3 of the tool parts W1, W2, W3 coincide with the radial direction R of an intended in the opening O of the tool electrical cable together.

Durch das Verfahren der Werkzeugteile W1, W2, W3 in die in den Figuren 4A und 4B gezeigte zweite, geschlossene Stellung unter gleichzeitiger Erhitzung der Aufnahmebereiche A1, A2, A3 der Werkzeugteile wird der Mantel 30 des in der Öffnung O des Werkzeugs positionierten elektrischen Kabels angeschmolzen und gleichzeitig wird der an der Außenseite 31 des Mantels 30 verlaufende Abschnitt 25b des Teilbereiches 25 des elektrischen Schirmes 2 in den angeschmolzenen Abschnitt des Mantels 30 eingearbeitet bzw. eingedrückt.By moving the tool parts W1, W2, W3 in the in the FIGS. 4A and 4B shown second, closed position with simultaneous heating of the receiving areas A1, A2, A3 of the tool parts, the jacket 30 of the positioned in the opening O of the tool electric cable is melted and at the same time on the outside 31 of the jacket 30 extending portion 25b of the portion 25 of the electrical shield 2 incorporated in the fused portion of the shell 30 or pressed.

Die Werkzeugteile W1, W2, W3 verweilen dann hinreichend lange in der in den Figuren 4A und 4B gezeigten geschlossenen Stellung, um eine kreisringförmige äußere Kontur des zuvor angeschmolzenen Abschnittes des Mantels 30 sicherzustellen und um den in jenen Mantel 30 eingedrückten Abschnitt 25b des umgelegten Teilbereiches 25 des elektrischen Schirms 2 innerhalb der durch den Mantel 30 definierten Wand zu halten.The tool parts W1, W2, W3 then dwell sufficiently long in the in the FIGS. 4A and 4B shown closed position to an annular To ensure outer contour of the previously fused portion of the shell 30 and to keep the depressed in that shell 30 portion 25 b of the folded portion 25 of the electric screen 2 within the defined by the shell 30 wall.

Wenn das Material des Mantels 30 nach einer bestimmten Verweildauer des Werkzeugs in dem in den Figuren 4A und 4B gezeigten geschlossenen Zustand hinreichend weit abgekühlt ist, wird das Werkzeug geöffnet, indem die Werkzeugteile W1, W2, W3 wieder in die in den Figuren 3A und 3B gezeigte geöffnete Stellung überführt werden. Die Verweildauer der Werkzeugteile W1, W2, W3 im geschlossenen Zustand kann dabei einerseits im Vorhinein einstellbar und damit vorgebbar sein oder alternativ in Abhängigkeit von einer Temperaturmessung am Mantel 30 des zu bearbeitenden elektrischen Leiters erst während der Bearbeitung selbst festgelegt werden.If the material of the shell 30 after a certain residence time of the tool in the in the FIGS. 4A and 4B As shown in the closed state is sufficiently far cool, the tool is opened by the tool parts W1, W2, W3 back into the in the FIGS. 3A and 3B shown open position to be transferred. The dwell time of the tool parts W1, W2, W3 in the closed state can on the one hand be adjusted in advance and thus predefinable or alternatively depending on a temperature measurement on the jacket 30 of the electrical conductor to be processed only during the processing itself.

Zusammenfassend zeichnen sich das vorstehend beschriebene Verfahren zur Herstellung eines elektrischen Kabels sowie die zur Durchführung dieses Verfahrens vorgesehenen Vorrichtungen insbesondere durch Folgendes aus:In summary, the above-described method for producing an electric cable and the devices provided for carrying out this method are characterized in particular by the following:

Das zu bearbeitende elektrische Kabel wird mit einem (End-)Abschnitt, an dem es mit einem nach außen umgelegten Teilbereich seines elektrischen Schirmes versehen ist, in einer hierfür vorgesehenen Öffnung eines Werkzeugs positioniert, das zueinander verfahrbare Werkzeugteile umfasst.The electrical cable to be processed is positioned with an (end) section, on which it is provided with an outwardly folded portion of its electric screen, in an opening provided therefor of a tool comprising mutually movable tool parts.

Durch Verfahren der Werkzeugteile zueinander wird der Querschnitt der Öffnung reduziert, wobei zunächst die Litzen des umgelegten Teilbereiches des elektrischen Schirmes gesammelt und an der Außenseite des Mantels des zu bearbeitenden Leiters positioniert werden.By moving the tool parts relative to one another, the cross-section of the opening is reduced, wherein first the strands of the turned over portion of the electric screen are collected and positioned on the outside of the jacket of the conductor to be processed.

Gleichzeitig werden die Werkzeugteile erhitzt, so dass bei einem Auftreffen der Werkzeugteile auf den Mantel des zu bearbeitenden Leiters ein Anschmelzen des Mantels erfolgt und dieser in einen viskosen Zustand übergeht. Dies ermöglicht ein Eindrücken des umgelegten, äußeren Teilbereiches des elektrischen Schirmes in den Mantel, so dass jener Teilbereich des elektrischen Schirmes bzw. die diesen Teilbereich bildenden Litzen eines Schirmgeflechtes innerhalb des Mantels verlaufen.At the same time, the tool parts are heated, so that upon impact of the tool parts on the jacket of the conductor to be machined a melting of the shell takes place and this merges into a viscous state. This allows an impression of the folded, outer portion of the electrical screen in the jacket, so that that portion of the electric screen or the strands of a shield braid forming this portion extend within the shell.

Die Werkzeugteile werden anschließend für eine gewisse Zeitdauer in der geschlossenen Position gehalten, um dem in einen viskosen Schmelzbereich überführten Abschnitt des Mantels des zu bearbeitenden elektrischen Leiters eine definierte Form aufzuzwingen und um die in den Mantel eingedrückten Litzen des Schirmgeflechtes innerhalb des Mantels zu halten. (Gegebenenfalls kann das Werkzeug vor dem Schritt der Formgebung des viskosen Mantels zunächst wieder geringfügig geöffnet werden; je nachdem, welchen Außendurchmesser das Kabel in dem zuvor angeschmolzenen Abschnitt haben soll.)The tool parts are then held in the closed position for a certain period of time in order to impose a defined shape on the section of the jacket of the electrical conductor to be machined in the viscous melting region and to hold the braid braid pressed into the jacket inside the jacket. (Optionally, the tool may be slightly reopened before the viscous shell molding step, depending on the outer diameter of the cable in the previously fused section.)

Nach einem hinreichenden Abkühlen des Mantels wird das Werkzeug durch Verfahren der Werkzeugteile wieder geöffnet und das Kabel lässt sich entnehmen.After a sufficient cooling of the jacket, the tool is opened by moving the tool parts and the cable can be removed.

Abschließend kann noch eine äußere Fixierhülse auf den Endabschnitt des Kabels aufgebracht werden, in dem der nach außen umgelegte Teilbereich des elektrischen Schirmes in den Mantel des Kabels eingedrückt worden ist.Finally, an outer fixing sleeve can also be applied to the end section of the cable in which the portion of the electric screen folded outwards has been pressed into the jacket of the cable.
