Description

Die vorliegende Erfindung betrifft einen Kabelschuh für zumindest ein elektrisches Kabel, mit einem Kontaktierungsbereich und einem zu diesem in Längsrichtung beabstandeten Adercrimpbereich mit zumindest einem Paar von Adercrimpelementen, zur Aufnahme und Befestigung der Adern des elektrischen Kabels.The present invention relates to a cable lug for at least one electrical cable, having a contacting region and a longitudinally spaced wire crimping region with at least one pair of wire crimping elements for receiving and securing the wires of the electric cable.

Bei einem derartigen Kabelschuh erfolgt sowohl die elektrische als auch die mechanische Befestigung der Adern des elektrischen Kabels hauptsächlich über die auch als Krallen oder Flügel bezeichneten Adercrimpelemente. Zur Befestigung wird ein abisolierter Endabschnitt des Kabels in den Adercrimpbereich des Kabelschuhs eingelegt und mit diesem durch Umlegen der Adercrimpelemente verbunden, so dass die Adercrimpelemente den aus den Adern bestehenden Kabelkern umgreifen.In such a cable lug, both the electrical and the mechanical attachment of the wires of the electric cable takes place mainly via the wire crimping elements, which are also referred to as claws or wings. For attachment, a stripped end portion of the cable is inserted into the wire crimping area of the cable lug and connected thereto by folding over the wire crimping elements, so that the wire crimping elements surround the wire core consisting of the wires.

An eine derartige Verbindung werden zwei Hauptanforderungen gestellt. Zum einen soll eine möglichst verlustfreie Übertragung der elektrischen Ströme gewährleistet werden, bei der der Übergangswiderstand zwischen Kabel und Kabelschuh möglichst klein sein soll. Zum anderen muss die Verbindung zur Aufnahme mechanischer Kräfte, insbesondere einer Zugkraft zwischen dem Kabelkern und dem Kabelschuh, standhalten.There are two main requirements for such a connection. On the one hand a lossless transfer of electrical currents should be ensured, in which the contact resistance between the cable and cable lug should be as small as possible. On the other hand, the connection must withstand the absorption of mechanical forces, in particular a tensile force between the cable core and the cable lug.

Die Leitfähigkeit der Verbindung nimmt mit steigendem Verpressungsgrad der Adercrimpelemente mit dem Kabelkern zu, welcher der Kraft entspricht, die auf die Adercrimpelemente während des Befestigungsvorgangs ausgeübt wird. Bei der Verpressung kommt es zu einer plastischen Verformung der annähernd runden Adern zu einem unregelmäßig mehreckigen, etwa wabenförmigen Querschnitt und damit zu einer Verdichtung des Kabelkerns, wodurch die Kontaktfläche der Adern zueinander und zu dem Kabelschuh vergrößert wird. Wird nun die Presskraft weiter erhöht, verringert sich der Querschnitt der einzelnen Adern, so dass unter Umständen eine Abscherung der Adern erfolgt.The conductivity of the connection increases with increasing degree of crimping of the wire crimping elements with the cable core, which corresponds to the force exerted on the wire crimping elements during the fastening operation. During the compression, a plastic deformation occurs the approximately round wires to an irregular polygonal, approximately honeycomb-shaped cross section and thus to a compression of the cable core, whereby the contact surface of the wires to each other and to the cable lug is increased. If the pressing force is further increased, the cross-section of the individual wires is reduced, so that under certain circumstances a shearing of the wires takes place.

Auf jeden Fall ist bei einer Befestigung mit zu hohem Verpressungsgrad die mechanische Festigkeit der Verbindung beeinträchtigt, insbesondere ist die Belastungsfähigkeit für Zugkräfte vermindert.In any case, in a fastening with too high degree of compression, the mechanical strength of the connection is impaired, in particular the load capacity for tensile forces is reduced.

Um eine Beeinträchtigung der mechanischen Festigkeit der Verbindung oder eine Abscherung von Adern zu vermeiden, wird daher der Kabelschuh mit einer moderaten Kraft mit den Adern verpresst. Diese Lösung stellt jedoch nur einen Kompromiss dar, da bei einem mittleren Verpressungsgrad die elektrische Verbindung noch nicht ihren kleinstmöglichen Übergangswiderstand aufweist, was sich durch entsprechende Widerstandsmessungen nachweisen lässt.In order to avoid an impairment of the mechanical strength of the connection or a shearing of wires, therefore, the cable lug is pressed with a moderate force with the wires. However, this solution represents only a compromise, since at a medium degree of compression, the electrical connection does not yet have their lowest possible contact resistance, which can be detected by appropriate resistance measurements.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Kabelschuh bereitzustellen, der eine Verbindung mit dem Kabel mit hoher mechanischer Festigkeit und guter elektrischer Leitfähigkeit ermöglicht.It is therefore the object of the present invention to provide a cable lug which allows connection to the cable with high mechanical strength and good electrical conductivity.

Die Lösung der Aufgabe erfolgt durch einen Kabelschuh mit den Merkmalen des Anspruchs 1. Ein erfindungsgemäßer Kabelschuh für zumindest ein elektrisches Kabel weist einen Kontaktierungsbereich und einen zu diesem in Längsrichtung beabstandeten Adercrimpbereich mit zumindest einem Paar von Adercrimpelementen zur Aufnahme und Befestigung der Adern des elektrischen Kabels auf. Die Adercrimpelemente weisen zumindest einen ersten Crimpabschnitt und zumindest einen zweiten Crimpabschnitt auf, wobei die Abwicklung des ersten Crimpabschnitts in einer zu der Längsrichtung senkrechten Erstreckungsrichtung größer ist als die Abwicklung des zweiten Crimpabschnitts. Die Crimpabschnitte sind symmetrisch zu der Längsachse des Kabelschuhs ausgebildet.The object is achieved by a cable lug having the features of claim 1. An inventive cable lug for at least one electrical cable has a contacting region and a wire crimping region spaced therefrom with at least one pair of wire crimping elements for receiving and securing the wires of the electrical cable , The wire crimping elements have at least one first crimping section and at least one second crimping section wherein the unwinding of the first crimping section in an extension direction perpendicular to the longitudinal direction is greater than the unwinding of the second crimping section. The crimp sections are formed symmetrically to the longitudinal axis of the cable lug.

Die zweiten, kürzeren Crimpabschnitte gewährleisten bei einer Befestigung an dem elektrischen Kabel eine mechanisch belastbare Verbindung, die Zugkräfte zuverlässig aufnehmen kann. In dem Bereich der zweiten Crimpabschnitte erfolgt lediglich eine unregelmäßige plastische Verformung der einzelnen Adern, jedoch im Wesentlichen keine Querschnittsreduzierung.When secured to the electrical cable, the second, shorter crimping sections ensure a mechanically strong connection that can reliably absorb tensile forces. In the area of the second crimping sections, only an irregular plastic deformation of the individual wires occurs, but essentially no cross-sectional reduction.

Die ersten, längeren Crimpabschnitte können sich in den Kabelkern hinein, insbesondere zwischen die Adern erstrecken, wodurch die Kontaktfläche mit den Adern vergrößert wird. Ferner können sie eine zusätzliche Kompression der Adern bewirken, so dass die daraus resultierende Kontaktierung des Mantelkerns eine weitere Verbesserung der Leitfähigkeit erreicht wird.The first, longer crimping sections can extend into the cable core, in particular between the wires, whereby the contact area with the wires is increased. Furthermore, they can cause additional compression of the wires, so that the resulting contacting of the jacket core, a further improvement in the conductivity is achieved.

Bei einer bevorzugten Ausführungsform der Erfindung ist die Abwicklung des ersten Crimpabschnitts in der Erstreckungsrichtung um 2 bis 20 %, bevorzugt um 5 bis 15 % und insbesondere um 5 bis 10 % größer als die Abwicklung des zweiten Crimpabschnitts. Die genannten Längenunterschiede ermöglichen ein ausreichendes Eindringen des ersten Crimpabschnitts in den Kabelkern hinein.In a preferred embodiment of the invention, the unwinding of the first crimping section in the direction of extent is 2 to 20%, preferably 5 to 15% and in particular 5 to 10% greater than the unwinding of the second crimping section. The mentioned differences in length allow sufficient penetration of the first crimping section into the cable core.

Bevorzugt sind die endseitigen Kanten des ersten Crimpabschnitts und/oder die endseitigen Kanten des zweiten Crimpabschnitts parallel zu der Längsrichtung angeordnet. Dadurch werden eine ausreichende mechanische Festigkeit bzw. eine hohe elektrische Leitfähigkeit entlang der gesamten Länge der Crimpabschnitte erzielt.The end-side edges of the first crimping section and / or the end-side edges of the second crimping section are preferably arranged parallel to the longitudinal direction. This will provide sufficient mechanical Strength or a high electrical conductivity along the entire length of the Crimpabschnitte achieved.

Vorteilhafterweise weist jeweils ein Adercrimpelement einen ersten und einen zweiten Crimpabschnitt auf. Bei einem derartigen Kabelschuh sind also die beiden Crimpabschnitte an einem gemeinsamen Adercrimpelement vorgesehen, so dass beide Crimpabschnitte zugleich und insbesondere mit gleicher Presskraft gecrimpt werden können. Ferner entstehen im Adercrimpbereich keine Zwischenabschnitte, in denen keine mechanische und/oder elektrische Verbindung zwischen Kabel und Kabelschuh vorhanden ist.Advantageously, each wire crimping element has a first and a second crimping section. In such a cable lug so the two crimping sections are provided on a common wire crimping element, so that both crimping sections can be crimped at the same time and in particular with the same pressing force. Further arise in the wire crimping no intermediate sections in which no mechanical and / or electrical connection between cable and cable lug is present.

Bei einer vorteilhaften Ausführungsform der Erfindung ist ein Übergang von dem ersten Crimpabschnitt zu dem zweiten Crimpabschnitt als Stufe ausgebildet. Ein derartiges Adercrimpelement besitzt also eine L-förmige Gestalt. Dies bewirkt eine deutliche Trennung der beiden Crimpabschnitte voneinander, so dass bei einer Kabelverbindung beide Crimpabschnitte jeweils klar definierte mechanische und elektrische Eigenschaften aufweisen.In an advantageous embodiment of the invention, a transition from the first crimping section to the second crimping section is formed as a step. Such a wire crimping element thus has an L-shaped configuration. This causes a clear separation of the two crimping sections from one another, so that in the case of a cable connection both crimping sections each have clearly defined mechanical and electrical properties.

Alternativ ist es aber auch möglich, dass ein Übergang von dem ersten Crimpabschnitt zu dem zweiten Crimpabschnitt als ein Übergangsabschnitt ausgebildet ist, dessen endseitige Kante zu der Längsachse geneigt ist. Bei einem derartigen Kabelschuh nehmen die Kompression und damit die Leitfähigkeit innerhalb des Übergangsabschnitts vom zweiten Crimpabschnitt hin zum ersten Crimpabschnitt kontinuierlich zu.Alternatively, however, it is also possible for a transition from the first crimping section to the second crimping section to be formed as a transition section whose end-side edge is inclined to the longitudinal axis. In such a cable lug, the compression and thus the conductivity within the transition section continuously increase from the second crimping section to the first crimping section.

Gemäß einer weiteren bevorzugten Ausführungsform sind der erste und der zweite Crimpabschnitt an verschiedenen Crimpelementen vorgesehen. Bei einem derartigen Kabelschuh lassen sich der erste und zweite Crimpabschnitt unabhängig voneinander mit unterschiedlichen Verpressungsgraden crimpen, wodurch eine Optimierung der elektrischen und mechanischen Eigenschaften der Kabelverbindung erfolgen kann.According to a further preferred embodiment, the first and the second crimping section are provided on different crimping elements. In such a cable lug, the first and second crimping can be independently crimp with different degrees of compression, whereby an optimization of the electrical and mechanical properties of the cable connection can take place.

Es ist vorteilhaft, wenn der erste Crimpabschnitt an der dem Kontaktierungsbereich zugewandten Seite der Adercrimpelemente ausgebildet ist und der zweite Crimpabschnitt an der dem Kontaktierungsbereich abgewandten Seite der Adercrimpelemente ausgebildet ist. Bei einem derartigen Kabelschuh grenzt also der zweite Crimpabschnitt, der hauptsächlich im Hinblick auf die mechanischen Eigenschaften der Verbindung optimiert ist, an das isolierte Kabel an, während der unmittelbare Endbereich des Kabels mit dem zu dem Kontaktierungsbereich benachbarten ersten Crimpabschnitt verbindbar ist. Dadurch wird sichergestellt, dass eine eventuelle Schwächung des Aderquerschnitts durch den ersten Crimpabschnitt die mechanische Festigkeit der Verbindung nicht beeinträchtigt, da die mechanischen Kräfte hauptsächlich über den zwischen Kabel und dem ersten Crimpabschnitt liegenden zweiten Crimpabschnitt aufgenommen werden.It is advantageous if the first crimping section is formed on the side of the wire crimping elements facing the contacting area and the second crimping section is formed on the side of the wire crimping elements which faces away from the contacting area. In such a cable lug, therefore, the second crimping section, which is optimized mainly with regard to the mechanical properties of the connection, adjoins the insulated cable, while the immediate end area of the cable can be connected to the first crimping section adjacent to the contacting area. This ensures that a possible weakening of the wire cross section through the first crimping section does not affect the mechanical strength of the connection, since the mechanical forces are absorbed mainly by the second crimping section lying between the cable and the first crimping section.

Bei einer weiteren vorteilhaften Ausführungsform weist der Kabelschuh ferner einen zu dem Adercrimpbereich in Längsrichtung beabstandeten Mantelcrimpbereich mit einem Paar von Mantelcrimpelementen zur Aufnahme und Befestigung eines Kabelmantels auf. Dieser Mantelcrimpbereich bewirkt eine zusätzliche Zugentlastung, da er unmittelbar über den Kabelmantel übertragene Kräfte aufnimmt und dadurch den Adercrimpbereich entlastet.In a further advantageous embodiment, the cable lug further comprises a mantle crimping area longitudinally spaced from the wire crimping area, with a pair of mantle crimping elements for receiving and securing a cable sheath. This Mantelcrimpbereich causes additional strain relief, since it receives directly transmitted via the cable sheath forces and thereby relieves the Adercrimpbereich.

Daran schließt sich ein Adercrimpbereich 16 an, in dem symmetrisch zur Längsachse L zwei üblicherweise auch als Flügel oder Krallen bezeichnete Adercrimpelemente 18 vorgesehen sind. Diese sind nach oben gebogen und bilden eine U-förmige Aufnahme für einen abisolierten Endabschnitt eines hier nicht dargestellten Kabels. Fig. 1 shows a cable lug 10 according to the invention according to a first embodiment. This has at one end a substantially rectangular, planar contacting region 12, which is provided with a bore 14 for attachment. This is followed by a wire crimping region 16, in which two wire crimping elements 18, which are also commonly referred to as wings or claws, are provided symmetrically with respect to the longitudinal axis L. These are bent upwards and form a U-shaped receptacle for a stripped end portion of a cable, not shown here.

Zu dem Adercrimpbereich 16 benachbart ist ein Mantelcrimpbereich 24 mit einem Paar von Mantelcrimpelementen 26 zur Aufnahme und Befestigung der Isolierung des Kabels angeordnet.Adjacent to the core crimping region 16 is a sheath crimping region 24 having a pair of sheath crimping elements 26 for receiving and securing the insulation of the cable.

Die Adercrimpelemente 18 sind in einen ersten Crimpabschnitt 20 und einen zweiten Crimpabschnitt 22 unterteilt, wobei beide Crimpabschnitte 20, 22 in Richtung der Längsachse L gesehen die gleiche Länge aufweisen.The wire crimping elements 18 are subdivided into a first crimping section 20 and a second crimping section 22, wherein both crimping sections 20, 22 have the same length as seen in the direction of the longitudinal axis L.

Wie auch in der Abwicklung des Kabelschuhs 10 gemäß Fig. 2A zu erkennen ist, ist die Abwicklung des ersten Crimpabschnitts 20 in einer zu der Längsachse L senkrechten Erstreckungsrichtung größer als die Abwicklung des zweiten Crimpabschnitts 22. Der erste Crimpabschnitt 20 ist insbesondere dafür vorgesehen, den elektrischen Kontakt zu dem Kabel herzustellen, während der zweite Crimpabschnitt 22 hauptsächlich eine sichere mechanische Verbindung zwischen Kabel und Kabelschuh 10 gewährleistet. Die Kanten beider Crimpabschnitte 20, 22 verlaufen parallel zur Längsachse L. Die Grenzen zwischen den Crimpabschnitten 20, 22 sind ebenso wie in Fig. 2B und 2C durch gestrichelte Linien angedeutet.As in the development of the cable lug 10 according to Fig. 2A 1, the unwinding of the first crimping section 20 in a direction of extent perpendicular to the longitudinal axis L is greater than the unwinding of the second crimping section 22. The first crimping section 20 is intended in particular for making electrical contact with the cable, while the second crimping section 22 mainly ensures a secure mechanical connection between the cable and cable lug 10. The edges of both crimping sections 20, 22 are parallel to the longitudinal axis L. The boundaries between the crimping sections 20, 22 are as well as in FIG Figs. 2B and 2C indicated by dashed lines.

Die Abwicklung der Mantelcrimpelemente 26 ist etwas größer als die Abwicklung der Adercrimpelemente 18, um den im Bereich der Isolierung vergrößerten Querschnitt des Kabels möglichst vollständig umgreifen zu können.The development of the Mantelcrimpelemente 26 is slightly larger than the settlement of the Adercrimpelemente 18 in order to fully encompass the enlarged in the isolation area cross-section of the cable can.

Der Übergang zwischen dem ersten Crimpabschnitt 20 und dem zweiten Crimpabschnitt 22 ist als senkrecht zu den Kanten der Crimpabschnitte 20, 22 verlaufende Stufe ohne Ausbildung eines Übergangsbereichs ausgeführt. Die Adercrimpelemente besitzen demnach eine L-förmige Gestalt.The transition between the first crimping portion 20 and the second crimping portion 22 is perpendicular to the edges of the crimping portions 20, 22 running stage without forming a transition region. The wire crimping elements accordingly have an L-shaped configuration.

Die Adercrimpelementpaare 18 und die Mantelcrimpelementpaare 26 sind bezüglich der Längsachse L symmetrisch ausgebildet.The Adercrimpelementpaare 18 and the Mantelcrimpelementpaares 26 are formed symmetrically with respect to the longitudinal axis L.

Der Kabelschuh 10 ist mit einem nur abschnittsweise dargestellten Trägerstreifen 28 verbunden, von dem er vor oder nach Abschluss eines Stanz-, Biege- oder Befestigungsvorgangs entlang einer Trennstelle 32 abgetrennt wird. An einem Trägerstreifen 28 können mehrere Kabelschuhe 10 befestigt sein. Erfindungsgemäße Kabelschuhe können aber auch ohne Trägerstreifen hergestellt sein und in loser Schüttung bereitgestellt werden.The cable lug 10 is connected to a carrier strip 28 shown only in sections, from which it is separated along a separation point 32 before or after completion of a punching, bending or fastening operation. On a carrier strip 28 a plurality of cable lugs 10 may be attached. However, cable lugs according to the invention can also be produced without carrier strips and provided in bulk.

Fig. 2B zeigt einen Ausschnitt der Abwicklung einer zweiten Ausführungsform eines erfindungsgemäßen Kabelschuhs 10', bei dem eines von zwei Adercrimpelementen 18' sowie ein Teilbereich eines Kontaktierungsbereichs 12' dargestellt sind. Das Adercrimpelement 18' weist einen ersten Crimpabschnitt 20', einen zweiten Crimpabschnitt 22' sowie einen zwischen diesen angeordneten Übergangsabschnitt 30' auf. Fig. 2B shows a section of the development of a second embodiment of a cable lug 10 'according to the invention, in which one of two wire crimping elements 18' and a portion of a contacting region 12 'are shown. The wire crimping element 18 'has a first crimping section 20', a second crimping section 22 'and a transition section 30' arranged between them.

Die Abwicklung des ersten Crimpabschnitts 20' ist wie bei der ersten Ausführungsform in der zu der Längsachse L senkrechten Erstreckungsrichtung größer als die Abwicklung des zweiten Crimpabschnitts 22'. Die Kanten der Crimpabschnitte 20', 22' verlaufen parallel zur Längsachse L, während die Kante des Übergangsabschnitts 30' die beiden Crimpabschnitte 20', 22' verbindet, wobei die Kante des Übergangsabschnitts 30' um einen Winkel von etwa 35° zur Längsachse L geneigt ist. Die Kanten der Crimpabschnitte 20', 22' und des Übergangsabschnitts 30' sind nicht gekrümmt.The unwinding of the first crimping section 20 'is greater than the unwinding of the second crimping section 22' in the direction of extent perpendicular to the longitudinal axis L, as in the first embodiment. The edges of the crimping portions 20 ', 22' are parallel to the longitudinal axis L, while the edge of the transitional portion 30 'connects the two crimping portions 20', 22 ', the edge of the transitional portion 30' being inclined at an angle of about 35 ° to the longitudinal axis L. is. The edges of the crimping sections 20 ', 22' and the transition section 30 'are not curved.

Gemäß einer Abwandlung des Ausführungsbeispiels von Fig. 2B ist der zweite Crimpabschnitt durch den Übergangsabschnitt 30' gebildet. Der in Fig. 2B mit Bezugszeichen 22' versehene Abschnitt entfällt dann.According to a modification of the embodiment of Fig. 2B the second crimping section is formed by the transition section 30 '. The in Fig. 2B then provided with reference numeral 22 'section deleted.

Fig. 2C zeigt die Abwicklung eines Kabelschuhs 10" gemäß einer dritten Ausführungsform, wobei wiederum nur ein Teilbereich mit einem Adercrimpelement 18" und einem Teil eines Kontaktierungsbereichs 12" dargestellt ist. Das Adercrimpelement 18" weist ähnlich wie in Fig. 2B einen ersten Crimpabschnitt 20", einen sich daran anschließenden Übergangsabschnitt 30" und daran angrenzend einen zweiten Crimpabschnitt 22" auf, wobei die Abwicklung des ersten Crimpabschnitts 20" wie bei den vorhergehenden Ausführungsformen in der zu der Längsachse L senkrechten Erstreckungsrichtung größer als die Abwicklung des zweiten Crimpabschnitts 22" ist. Fig. 2C shows the development of a cable lug 10 "according to a third embodiment, wherein again only a partial area with a wire crimping element 18" and a part of a contacting area 12 "is shown Fig. 2B a first crimping section 20 ", a transition section 30" adjoining thereto and a second crimping section 22 "adjacent thereto, the unwinding of the first crimping section 20" being larger in the direction of extent perpendicular to the longitudinal axis L than the unwinding of the second Crimping section 22 "is.

Die Kante des Übergangsabschnitts 30" ist im Vergleich zur Ausführungsform von Fig. 2B nur etwa um 20° zur Längsachse L geneigt und in einem dem ersten Crimpabschnitt 20" benachbarten Bereich gerade, während sie in einem zum zweiten Crimpabschnitt 22" benachbarten Bereich eine Krümmung aufweist. Ferner ist die Ecke des Adercrimpelements 18" im Bereich des zweiten Crimpabschnitts 22" mit einem Winkel von etwa 45° gebrochen.The edge of the transition section 30 "is compared to the embodiment of Fig. 2B tilted only about 20 ° to the longitudinal axis L and in a the first crimping section 20 "adjacent area straight, while in a region adjacent to the second crimping section 22" has a curvature. Further, the corner of the wire crimping element 18 "is broken at an angle of about 45 ° in the region of the second crimping section 22".

Fig. 3A und 3B zeigen Querschnittsansichten eines an einem Kabel befestigten Kabelschuhs 10. Das Kabel besitzt einen Kabelkern 34, welcher eine Anzahl von Einzellitzen oder Adern 36 umfasst. Die umgebogenen Crimpabschnitte 20, 22 komprimieren den Kabelkern 34, so dass sich der ursprünglich runde Querschnitt der Adern 36 eine unregelmäßig mehreckige, etwa wabenförmige Form annimmt. Dadurch vergrößert sich die Kontaktfläche der Adern 36 zueinander und zu dem Kabelschuh 10. FIGS. 3A and 3B 12 show cross-sectional views of a cable lug 10 attached to a cable. The cable has a cable core 34 comprising a number of individual strands or cores 36. The bent crimp sections 20, 22 compress the cable core 34, so that the originally round cross section of the cores 36 is irregularly polygonal, assumes approximately honeycomb shape. As a result, the contact surface of the wires 36 to each other and to the cable lug 10 increases.

Gemäß Fig. 3B umgreifen die zweiten Crimpabschnitte 22 die Adern 36 im Wesentlichen nur entlang des Umfangs des Kabelkerns 34, wobei der Verpressungsgrad so gewählt ist, dass lediglich eine Verformung der Adern 34 weitgehend ohne Querschnittsverringerung erfolgt.According to Fig. 3B The second crimping sections 22 surround the cores 36 essentially only along the circumference of the cable core 34, wherein the degree of crimping is selected so that only a deformation of the cores 34 takes place largely without a reduction in cross section.

Gemäß Fig. 3A erstrecken sich Endabschnitte 38 der ersten Crimpabschnitte 20, die an ihrem freien Ende mit Fasen zur Unterstützung der Einrollbewegung während des Crimpvorgangs versehen sind, in den Kabelkern 34 hinein, so dass sich die Endabschnitte 38 zum Teil zwischen einzelne Adern 36 erstrecken.According to Fig. 3A End portions 38 of the first crimping portions 20, which are provided at their free end with chamfers for assisting the curling movement during the crimping operation, extend into the cable core 34 so that the end portions 38 partially extend between individual wires 36.

Dadurch wird zum einen die Kontaktfläche mit den Adern 36 erhöht, zum anderen bewirken die Endabschnitte 38 aufgrund ihres zusätzlichen Volumens im Vergleich mit den zweiten Crimpabschnitten 22 eine Verdrängung der Adern 36 und damit eine zusätzliche Kompression des Mantelkerns 34 im Bereich des ersten Crimpabschnitts 20, wodurch ein gegenüber dem in Fig. 3B dargestellten zweiten Crimpabschnitt 22 erhöhter Verpressungsgrad und damit die gewünschte Verbesserung der Leitfähigkeit erreicht wird. Dabei kann eine geringfügige Verringerung des Aderquerschnitts auftreten, die aber hingenommen werden kann, da sie an dem nur noch geringfügig durch Zugkräfte belasteten Ende des Kabels erfolgt.As a result, on the one hand the contact surface with the wires 36 is increased, on the other hand cause the end portions 38 due to their additional volume in comparison with the second crimping sections 22 a displacement of the wires 36 and thus an additional compression of the sheath core 34 in the region of the first crimping section 20, thereby one opposite the in Fig. 3B shown second crimping 22 increased Verpressungsgrad and thus the desired improvement in the conductivity is achieved. In this case, a slight reduction of the core cross section occur, but which can be accepted, since it takes place at the only slightly loaded by tensile forces end of the cable.

Abschließend soll noch angemerkt werden, dass der erste Crimpabschnitt und der zweite Crimpabschnitt auch an verschiedenen Adercrimpelementen vorgesehen sein kann, d.h. die beiden Crimpabschnitte sind durch einen Spalt voneinander getrennt.Finally, it should be noted that the first crimping section and the second crimping section can also be provided on different wire crimping elements, ie the two crimping sections are separated from each other by a gap.

Weiterhin können die erfindungsgemäßen Kabelschuhe neben der vorstehend beschriebenen offenen Bauweise mit krallenförmigen Crimpabschnitten auch als geschlossene Kabelschuhe mit hülsenförmigen Crimpabschnitte ausgebildet sein.Furthermore, the cable lugs according to the invention may be formed in addition to the open design described above with claw-shaped crimping sections as closed cable lugs with sleeve-shaped crimping sections.
