Description

Die Erfindung betrifft eine Vorrichtung zum Ankontaktieren des Leitungsschirms eines Koaxialkabels, mit einem Kontaktelement, welches eine Kontaktfläche und eine erste Ausnehmung aufweist, und mit einem Spannelement, welches eine zweite Ausnehmung aufweist, wobei die Innenleiterisolation des Koaxialkabels durch beide Ausnehmungen hindurchgeführt ist und ein freigelegter Abschnitt des Leitungsschirms klemmend zwischen dem Spannelement und dem Kontaktelement angeordnet ist.The invention relates to a device for contacting the cable shield of a coaxial cable, with a contact element having a contact surface and a first recess, and with a clamping element having a second recess, wherein the inner conductor insulation of the coaxial cable is passed through both recesses and an exposed portion the cable shield is arranged clamped between the clamping element and the contact element.

Der Anschluss eines Koaxialkabels an ein elektronisches Gerät oder einen elektrischen Steckverbinder erfordert einen gewissen Montageaufwand, wobei ein relativ großer Anteil dieses Aufwandes auf die Ankontaktierung des Leitungsschirms entfällt. Nach dem Freilegen eines Abschnitts des Leitungsschirms durch das abschnittsweise Entfernen des Kabelmantels ist der Leitungsschirm auf eine vorgesehene Länge und Form zu bringen und anschließend mit einem geeigneten Metallgegenstand mechanisch und elektrisch zu verbinden. Besonders die Formung des aus einem Leitergeflecht bestehenden Leitungsschirms erfordert zumeist einen erheblichen Aufwand.The connection of a coaxial cable to an electronic device or an electrical connector requires a certain assembly effort, with a relatively large proportion of this effort is attributable to the Ankontaktierung the cable shield. After exposing a portion of the cable shield by removing the cable sheath in sections, the cable shield is to be provided to an intended length and shape and then mechanically and electrically connected to a suitable metal object. In particular, the formation of the existing of a conductor mesh cable shield usually requires a considerable effort.

Zum elektrischen Anschluß eines Leitungsschirms ist es beispielsweise bekannt, einen hülsenartigen Gegenstand zwischen das Geflecht des Leitungsschirms und die Innenleiterisolation zu schieben und dann einen weiteren Metallkörper von außen auf den hülsenartigen Gegenstand zu crimpen. Hierzu ist das Schirmgeflecht zunächst aufzuweiten.For electrical connection of a cable shield, it is known, for example, to push a sleeve-like object between the braid of the cable shield and the inner conductor insulation and then to crimp another metal body from the outside onto the sleeve-like object. For this purpose, the braid is first expand.

Eine andere Möglichkeit besteht darin, das Schirmgeflecht aufzutrennen, um 180° umzuschlagen und anschließend zwischen zwei miteinander zu verbindende metallene Gegenstände zu legen.Another possibility is to separate the braided shield, to flip over 180 ° and then to place between two metal objects to be joined together.

Diese Arten der elektrischen Anbindung erfordern jeweils eine sorgfältige Vorbehandlung des Leitungsschirms, die den Leitungsschirm nicht beschädigen darf, um die Kontaktgabe und die Abschirmwirkung des Leitungsschirms nicht zu beeinträchtigen.These types of electrical connection each require a careful pre-treatment of the cable shield, which must not damage the cable shield, so as not to affect the contact and the shielding effect of the cable shield.

Aus der deutschen Auslegeschrift DE 22 55 785 B2 ist eine Vorrichtung bekannt, bei der ein Leitungsschirm eines Koaxialkabels klemmend zwischen scheibenförmigen Kontaktelementen gehalten wird, die ihrer Funktion nach zugleich Spannelemente ausbilden. Zur Befestigung des Leitungsschirms offenbart das Dokument lediglich, dass dieser vor dem Anfügen des zweiten Kontaktelements am ersten Kontaktelement stehend hochgebogen wird. Die Figur 2 dieses Dokuments zeigt, dass der klemmend zwischen den Spann- bzw. Kontaktelementen gehaltene Abschnitt des Leitungsschirms sehr viel kürzer ist als der vom äußeren Kabelmantel freigelegte Abschnitt des Koaxialkabels, so dass der Leitungsschirm offensichtlich gekürzt wurde. Das Ablängen eines geflochtenen Leitungsschirms stellt im Allgemeinen einen relativ aufwendigen Montageschritt dar.From the German Auslegeschrift DE 22 55 785 B2 a device is known in which a cable shield of a coaxial cable is clamped between disc-shaped contact elements, which at the same time form clamping elements according to their function. For fixing the cable shield, the document merely reveals that it is bent upright before attaching the second contact element to the first contact element. The FIG. 2 of this document shows that the portion of the cable shield held between the clamping or contact elements by clamping is much shorter than the portion of the coaxial cable exposed by the outer cable jacket, so that the cable shield has obviously been shortened. The cutting of a braided cable shield is generally a relatively expensive assembly step.

Es stellte sich die Aufgabe der Erfindung, eine Vorrichtung zu schaffen, welche die Ankontaktierung eines Leitungsschirms eines Koaxialkabels montagetechnisch vereinfacht und elektrisch verbessert.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der freigelegte Abschnitt des Leitungsschirms durch ein Zusammenschieben in axialer Richtung des Koaxialkabels senkrecht zur Kabelachse aufgestaucht ist.It was an object of the invention to provide a device which simplifies the assembly of a cable shield of a coaxial cable mounting technology and electrically improved.
This object is achieved in that the exposed portion of the cable shield is plunged by pushing together in the axial direction of the coaxial cable perpendicular to the cable axis.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung von zwei Ausführungsbeispielen anhand der Zeichnung. Die Figuren zeigen ein Koaxialkabel mit einem Kontaktelement bzw. mit einem Kontaktelement und einem Spannelement und verdeutlichen die Montageschritte zur Herstellung der erfindungsgemäßen Vorrichtung.Advantageous embodiments of the invention will become apparent from the following description of two embodiments with reference to FIG Drawing. The figures show a coaxial cable with a contact element or with a contact element and a clamping element and illustrate the assembly steps for producing the device according to the invention.

Die Figur 1 zeigt ein Koaxialkabel mit einem typischen konzentrischen Aufbau. Das Koaxialkabel 1 weist einen Innenleiter 5 auf, der von einer Innenleiterisolation 4 umgeben ist. Die Innenleiterisolation 4 ist von einem Außenleiter 2 umfasst, der hier vereinfacht als eine dunkle Fläche dargestellt ist, und der üblicherweise als ein Geflecht einer Vielzahl dünner Leitungsadern ausgebildet ist. Aufgrund seiner komplizierten Struktur ist die Bearbeitung und elektrische Kontaktierung des Außenleiters 2 im Allgemeinen deutlich aufwendiger als die Kontaktierung des Innenleiters 5. Der Außenleiter 2 ist bei den meisten Anwendungen mit einer elektrischen Masse verbunden und hat die Funktion, insbesondere hochfrequente elektrische Störsignale abzuschirmen. Der Außenleiter 2 wird daher hier auch als Leitungsschirm bezeichnet. Die äußerste Umhüllung des Koaxialkabels 1 bildet ein Kabelmantel 3, der zur Isolierung des Leitungsschirms 2 sowie zum mechanischen Schutz des Koaxialkabels 1 dient.The FIG. 1 shows a coaxial cable with a typical concentric structure. The coaxial cable 1 has an inner conductor 5 which is surrounded by an inner conductor insulation 4. The inner conductor insulation 4 is comprised of an outer conductor 2, which is shown here in simplified form as a dark surface, and which is usually formed as a mesh of a plurality of thin conductor wires. Due to its complicated structure, the processing and electrical contacting of the outer conductor 2 is generally much more complicated than the contacting of the inner conductor 5. The outer conductor 2 is connected in most applications with an electrical ground and has the function to shield especially high-frequency electrical noise. The outer conductor 2 is therefore also referred to here as a cable shield. The outermost enclosure of the coaxial cable 1 forms a cable sheath 3, which serves for the insulation of the cable shield 2 and for the mechanical protection of the coaxial cable 1.

In der Darstellung der Figur 1 sind Abschnitte des Kabelmantels 3 und der Innenleiterisolation 4 entfernt, so dass der Innenleiter 5 und der Leitungsschirm 2 abschnittsweise freigelegt sind. In der Figur 1 ist zudem ein Kontaktelement 6 erkennbar, welches eine zentrale Ausnehmung 7 aufweist, durch die das Koaxialkabel 1 hindurchgeführt ist. Der Durchmesser der Ausnehmung 7 ist etwas größer als der Außendurchmesser des Koaxialkabels 1 im Bereich der Kabelmantels 3, so dass das Kontaktelement 6 am freigelegten Abschnitt des Leitungsschirms 2 sitzt und eine, sich an die Ausnehmung 7 anschließende rohrförmige Anformung 12 den Kabelmantel 3 übergreift.In the presentation of the FIG. 1 are sections of the cable sheath 3 and the inner conductor insulation 4 removed, so that the inner conductor 5 and the cable shield 2 are partially exposed. In the FIG. 1 In addition, a contact element 6 can be seen, which has a central recess 7, through which the coaxial cable 1 is passed. The diameter of the recess 7 is slightly larger than the outer diameter of the coaxial cable 1 in the region of the cable sheath 3, so that the contact element 6 sits on the exposed portion of the cable shield 2 and a, adjoining the recess 7 tubular Anformung 12 the cable sheath 3 overlaps.

An den Außenrand einer etwa kreisringförmigen Kontaktfläche 13 ist an das Kontaktelement 6 ein umlaufender Kragen 10 angeformt, der sich in Richtung des freien Endes des Koaxialkabels 1 erstreckt. Der Kragen 10 weist mehrere Rast- oder Crimpelemente 11 auf.At the outer edge of an approximately annular contact surface 13, a circumferential collar 10 is formed on the contact element 6, which extends in the direction of the free end of the coaxial cable 1. The collar 10 has a plurality of latching or crimping elements 11.

Die Rast- oder Crimpelemente 11 sind zur formschlüssigen Anbindung eines scheibenförmigen Spannelements 8 vorgesehen, welches in der Figur 2 dargestellt ist. Das Spannelement 8 weist ebenfalls eine Ausnehmung 9 auf, deren Durchmesser aber nur geringfügig größer ist als der Außendurchmesser der Innenleiterisolation 4. Nach dem Hindurchführen des freien Endes des Koaxialkabels 1 durch die Ausnehmung 9 trifft beim Verschieben des Spannelements 8 in Richtung auf das Kontaktelement 6, das Spannelement 8 auf den Leitungsschirm 2 und drückt diesen zusammen.The latching or crimping elements 11 are provided for the positive connection of a disk-shaped clamping element 8, which in the FIG. 2 is shown. The clamping element 8 also has a recess 9, whose diameter is only slightly larger than the outer diameter of the inner conductor insulation 4. After passing the free end of the coaxial cable 1 through the recess 9 hits when moving the clamping element 8 in the direction of the contact element 6, the clamping element 8 on the cable shield 2 and presses it together.

Dabei staucht sich der Leitungsschirm 2 zwischen dem Spannelement 8 und dem Kontaktelement 6, wie die Figuren 3 und 4 zeigen, senkrecht zur Kabelachse balgartig auf. Besonders deutlich ist dies in der Figur 4 ersichtlich, in der das Spannelement 8 transparent dargestellt ist.In this case, the cable shield 2 upsets between the clamping element 8 and the contact element 6, as the FIGS. 3 and 4 show, perpendicular to the cable axis on bellows. This is especially clear in the FIG. 4 can be seen, in which the clamping element 8 is shown transparent.

Beim Weiterschieben des Spannelements 8 kommt dieses am ersten Kontaktelement 6 zur Anlage und kann mit diesem durch Verrasten oder Vercrimpen formschlüssig oder kraftschlüssig verbunden werden.When pushing the clamping element 8 this comes to rest on the first contact element 6 and can be positively or non-positively connected thereto by latching or crimping.

In der Figur 6 ist das Spannelement wiederum transparent dargestellt und daher nicht als Einzelteil erkennbar. Ersichtlich ist, dass der zusammengeschobene Leitungsschirm 2 dicht an der Kontaktfläche 13 des Kontaktelements 6 anliegt und dabei eine angedeutete lamellenartige Struktur aufweist. Der zusammengeschobene Leitungsschirm 2 bildet so eine doppellagige Schicht seines Leitungsgeflechts zwischen dem Spannelement 8 und dem Kontaktelement 6 aus.In the FIG. 6 the clamping element is again shown transparent and therefore not recognizable as a single part. It can be seen that the pushed-together cable shield 2 bears tightly against the contact surface 13 of the contact element 6 and thereby has an indicated lamellar structure. The pushed-together cable shield 2 thus forms a double-layered layer of its line mesh between the clamping element 8 and the contact element 6.

Im Gegensatz zu dem zwingend aus einem Metall bestehenden Kontaktelement 6 kann das Spannelement 8 grundsätzlich aus einem beliebigen Material und insbesondere aus einem Kunststoff bestehen.In contrast to the necessarily made of a metal contact element 6, the clamping element 8 can basically consist of any material and in particular of a plastic.

Neben der montagetechnisch einfachen Befestigung und den sehr guten elektrischen Eigenschaft durch eine großflächige Verbindung des Leitungsschirms 2 zu dem Kontaktelement 6 und gegebenenfalls auch zu dem Spannelement 8 ergibt sich als weiterer Vorteil, dass außer dem Freilegen eines Abschnitts des Leitungsschirms 2 durch ein Abisolieren des Kabelmantels 3 keine weitere Bearbeitung des Leitungsschirms 2, wie etwa ein Abschneiden oder eine besondere Ausformung, vor dessen Kontaktierung durch das Zusammenführen des Spannelements 8 und des Kontaktelements 6 erforderlich ist, und damit die Ankontaktierung auf eine besonders einfache und kostengünstige Weise erfolgen kann.In addition to the mounting technology simple attachment and the very good electrical property by a large-scale connection of the cable shield 2 to the contact element 6 and optionally also to the clamping element 8 results in the further advantage that except exposing a portion of the cable shield 2 by stripping the cable sheath. 3 no further processing of the cable shield 2, such as a cut or a special shape, before contacting by the merging of the clamping element 8 and the contact element 6 is required, and thus the Ankontaktierung can be done in a particularly simple and cost-effective manner.

Die in den Figuren 5 und 6 dargestellte Vorrichtung kann auf eine hier nicht näher beschriebene Weise, mit einem Gehäuseteil eines elektronischen Geräts oder mit einem Teil eines elektrischen Steckverbinders verbunden werden.The in the FIGS. 5 and 6 shown device can be connected in a manner not described here in detail, with a housing part of an electronic device or with a part of an electrical connector.

Eine Ausführungsvariante einer Vorrichtung zum Ankontaktieren eines Leitungsschirms ist in den Figuren 7 bis 10 dargestellt. Im Vergleich zu dem zuvor beschriebenen Ausführungsbeispiel sind das Kontaktelement 6' und das Spannelement 8' hier komplexer geformt und weisen insbesondere jeweils angeformte Rastlaschen 14, 15 auf, welche mit Rastausnehmungen 16 bzw. Rastnasen 17 versehen sind.
Die Figur 7 zeigt einen Montagezustand, in dem sowohl das Kontaktelement 6' als auch das Spannelement 8' bereits auf das vorbereitete Koaxialkabel 1 aufgeschoben sind. Dabei sind sie so weit zusammengeführt sind, dass sich der Leitungsschirm 2 zwischen dem Kontaktelement 6' und dem Spannelement 8' schon ein Stück weit aufstaucht.An embodiment of a device for contacting a cable shield is in the FIGS. 7 to 10 shown. Compared to the embodiment described above, the contact element 6 'and the clamping element 8' here are more complex and in particular each have molded locking tabs 14, 15 which are provided with locking recesses 16 and locking lugs 17.
The FIG. 7 shows a mounting state in which both the contact element 6 'and the clamping element 8' are already pushed onto the prepared coaxial cable 1. They are so far brought together that the cable shield 2 between the contact element 6 'and the clamping element 8' already rises a bit.

Bei der weiteren Annäherung des Spannelements 8' an das Kontaktelement 6' verrasten schließlich die Rastnasen 17 des Spannelements 8' mit den Rastausnehmungen 16 des Kontaktelements 6'. Damit ist der in der Figur 8 dargestellte Montagezustand erreicht, bei dem der aufgestauchte Leitungsschirm 2 nun zwischen dem Spannelement 8' und Kontaktelement 6' klemmend befestigt ist.In the further approximation of the clamping element 8 'to the contact element 6' finally engage the locking lugs 17 of the clamping element 8 'with the recesses 16 of the contact element 6'. This is the one in the FIG. 8 achieved assembly state shown in which the upset cable shield 2 is now clamped between the clamping element 8 'and contact element 6'.

In der Figur 8 ist eine von mehreren Crimplaschen 18 erkennbar, deren Endabschnitte in einem weiteren Montageschritt nach innen umgebogen werden, wodurch sich die in der Figur 9 dargestellte Vorrichtung ergibt. Wie die Schnittansicht der Figur 10 verdeutlicht, drücken die Endabschnitte der Crimplaschen 18 oberhalb des Außenrands des Spannelements 8' gegen den aufgefalteten Leitungsschirm 2, wodurch dieser formschlüssig befestigt und zugleich elektrisch kontaktiert wird. Auf Grund dieser, zur Anlage des Leitungsschirm 2 an der inneren Kontaktfläche 13' des Kontaktelements 6' zusätzlichen elektrischen Kontaktierung kann das Spannelement 8' ohne weitere Nachteile besonders kostengünstig aus einem nichtleitenden Kunststoffmaterial gefertigt sein.In the FIG. 8 one of a plurality of Crimplaschen 18 can be seen, the end portions are bent in a further assembly step inwardly, resulting in the in the FIG. 9 shown device results. Like the sectional view of the FIG. 10 illustrates, press the end portions of the Crimplaschen 18 above the outer edge of the clamping element 8 'against the unfolded cable shield 2, whereby it is positively secured and at the same time electrically contacted. On the basis of this, for the installation of the cable shield 2 on the inner contact surface 13 'of the contact element 6' additional electrical contact, the clamping element 8 'can be made particularly cost-effective from a non-conductive plastic material without further disadvantages.
