Einrichtung zum elektrisch leitenden Kontaktieren eines abschnittsweise abisolierten Außenleiters eines KoaxialkabelsDevice for electrically conductive contacting of a stripped outer conductor of a coaxial cable
Die Erfindung betrifft eine Einrichtung der im Oberbegriff des Anspruchs 1 genannten Art zum elektrisch leitenden Kontaktieren eines abschnittsweise abisolierten Außenleiters eines Koaxialkabels. Derartige Einrichtungen sind allgemein bekannt, beispielsweise durch EP 0 744 788 AI. Sie dienen beispielsweise zum Anschließen eines Erdungskabels an einen abschnittsweise abisolierten Außenleiter eines Koaxialkabels . Durch EP 0 987 483 Bl, EP 0 982 524 Bl und EP 978The invention relates to a device of the type mentioned in the preamble of claim 1 for electrically conductive contacting of a stripped outer conductor of a coaxial cable. Such devices are generally known, for example from EP 0 744 788 AI. They are used, for example, to connect an earthing cable to an outer conductor of a coaxial cable that is stripped in sections. By EP 0 987 483 Bl, EP 0 982 524 Bl and EP 978
678 Bl ist jeweils eine Einrichtung bekannt, die einen als um das zu kontaktierende Koaxialkabel spannbare Schelle ausgebildeten Grundkörper aufweist, der in Um- fangsrichtung offen ausgebildet ist und an seinen Enden abgewinkelte oder abgebogene Laschen aufweist, die in Montagepostion miteinander verbindbar sind, wobei der Grundkörper ein Trägerelement aus Metall aufweist, das sich bis in die Laschen erstreckt. Die bekannte Einrichtung weist ferner Mittel zum Herstellen einer elek- trisch leitenden Verbindung zwischen dem Außenleiter des Koaxialkabels und dem Trägerelement auf, die ein durch eine Litze oder ein Geflechtband aus Metall gebildetes Kontaktelement aufweisen. Das Kontaktelement gelangt beim Spannen des Grundkörpers einerseits an der radialen Außenfläche des abisolierten Koaxialkabels und andererseits an der radialen Innenfläche des Trägerelementes zur Anlage, so daß zwischen dem Außenleiter des Koaxialkabels und dem Trägexrelement eine elektrisch leitende Verbindung hergestellt ist . Die bekannte Einrichtung weist ferner Anschlußmittel zum Anschließen eines Erdungskabels an das Trägerelement auf. Die Anschlußmittel sind bei der bekannten Einrichtung durch eine an dem Erdungskabel gebildete Anschlußöse gebildet, die mittels einer Schraube, die in eine an einer der Laschen gebildete Gewindebohrung einschraubbar ist, mit dem Trägerelement des Grundkörpers verschraubbar ist, so daß über die Anschlußöse eine elektrisch lei- tende Verbindung zwischen dem Eirdungskabel und dem Trägerelement und damit zwischen dem Erdungskabel und dem Außenleiter des Koaxialkabels herstellbar ist. Durch WO 02/061884 AI ist eine Einrichtung der im Oberbegriff des Anspruchs 1 genannten Art bekannt. Bei der aus dieser Druckschrift bekannten Einrichtung weisen die Anschlußmittel ein nach Art eines Kabelschuhes ausgebildetes Anschlußelement auf, das mit dem Trägerelement oder mit einem mit diesem elektrisch leitend verbundenen Teil fest und elektrisch leitend verbunden ist. Die aus der Druckschrift bekannte Einrichtung ist einfach und kostengünstig herstellbar und ermöglicht auf schnelle und einfache Weise die Herstellung einer elektrisch leitenden Verbindung zwischen dem Trägerelement der Einrichtung und einem elektrisch leitenden Bauteil, beispielsweise einem Eirdungskabel. Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der im Oberbegriff dies Anspruchs 1 genannten Art anzugeben, die noch einfacher und damit kostengünstiger herstellbar ist. Die Erfindung löst sich von dem Gedanken, beispielsweise eine Erdung eines abisolierten Außenleiters eines Koaxialkabels dadurch herzustellen, daß dieses elektrisch leitende Bauteil, beispielsweise ein Metall- teil eines Mastes einer Mobilfunk-Sendeanlage, über ein Erdungskabel mit dem Trägerelement der Einrichtung zu verbinden. Ihr liegt vielmehr der Gedanke zugrunde, die erfindungsgemäße Einrichtung so auszubilden, daß ein Anschließen des Trägerelementes an das elektrisch lei- tende Bauteil auch ohne Erdungskabel möglich ist. Hierzu sieht die erfindungsgemäße Lehre vor, daß das Anschlußelement wenigstens in einem sich von seinem freien Ende bis zu einem Verbindungspunkt mit dem Grundkörper erstreckenden Bereich streifenförmig und im Quer- schnitt flach ausgebildet ist. Erfindungsgemäß wird das flache, streifenförmige Anschlußelement unmittelbar mit dem elektrisch leitenden Bauteil, beispielsweise einem Metallteil eines Mastes einer Mobilfunk-Sendeanlage verbunden. Auf diese Weise ist es unter Verzicht auf ein Erdungskabel möglich, beispielsweise einen abisolierten Außenleiter eines Koaxialkabels zu erden. Die Verbindung des Anschlußelementes mit dem elektrisch leitenden Bauteil kann eine lösbare Verbindung, beispielsweise eine Schraubverbindung, oder eine unlös- bare Verbindung, beispielsweise eine Schweiß- oder Lötverbindung sein. Die erfindungsgemäße Einrichtung ist besonders einfach und damit kostengünstig herstellbar und besonders einfach handhabbar. Grundsätzlich kann das Anschlußelement im wesentlichen starr ausgebildet sein. Eine vorteilhafte Weiterbildung sieht vor, daß das Anschlußelement biegsam ist. Auf diese Weise ist die Handhabung der erfindungsgemäßen Einrichtung weiter vereinfacht, da das An- Schlußelement durch Biegen in eine zu Verbindung mit dem elektrisch leitenden Bauteil gewünschte Position gebracht werden kann. Zweckmäßigerweise ist bei der vorgenannten Aus- führungsfor das Anschlußelement im xingebogenen Zustand im wesentlichen plan. Falls die Verbindung zwischen dem Anschlußelement und dem elektrisch leitenden Bauteil , beispielsweise einem Metallteil eines Mastes einer Mobilfunk-Sende- anläge, eine lösbare Verbindung ist, so ist es vorteilhaft, daß das Anschlußelement wenigstens eine Ausnehmung, vorzugsweise eine Bohrung, auf-weist zum Hindurchführen einer Schraube oder dergleichen zur Herstellung einer elektrisch leitenden Verbindung zwischen dem An- Schlußelement und dem elektrisch leitenden Bauteil. Auf diese Weise ist die Verbindung des Anschlußelementes mit dem elektrisch leitenden Bauteil wesentlich vereinfacht und zeitsparend gestaltet . Grundsätzlich kann das Anschlußelement als separa- tes Bauteil ausgebildet sein, das beispielsweise klemmend zwischen den Trägerelementen uncl einem mit dem Trägerelement verbundenen Verstärkuncjselement gehalten ist. Eine besonders einfache und kostengünstig herstellbare und besonders einfach handhabbare Ausfüh- rungsform sieht vor, daß das AnschluSelement einstückig mit dem Trägerelement oder einem mit dem Trägerelement elektrisch leitenden Verstärkungselement ausgebildet ist . Eine andere vorteilhafte Weiterbildung der erfin- dungsgemäßen Lehre sieht vor, daß das Anschlußelement entlang seiner Ausdehnung in der Draufsicht einen im wesentlichen konstanten Querschnitt aufweist. Weitere, vorteilhafte Weiterbildungen der erfindungsgemäßen Lehre sind in den Unteransprüchen enthal- ten. Die Erfindung wird nachfolgend anhand der beigefügten Zeichnung, die ein Ausfuhrungsbeispiel darstellt, näher erläutert.678 B1 a device is known in each case which has a base body which is designed as a clamp which can be tensioned around the coaxial cable to be contacted, which is open in the circumferential direction and has angled or bent tabs at its ends which can be connected to one another in the assembly position, the base body has a carrier element made of metal, which extends into the tabs. The known device furthermore has means for producing an electrically conductive connection between the outer conductor of the coaxial cable and the carrier element, which have a contact element formed by a wire or a braid band made of metal. The contact element comes to bear when the base body is tensioned on the one hand on the radial outer surface of the stripped coaxial cable and on the other hand on the radial inner surface of the carrier element, so that an electrically conductive connection is established between the outer conductor of the coaxial cable and the support element. The known device also has connection means for connecting an earth cable to the carrier element. In the known device, the connection means are formed by a connection eyelet formed on the grounding cable, which can be screwed to the carrier element of the base body by means of a screw which can be screwed into a threaded bore formed on one of the tabs, so that an electrically conductive connection via the connection eyelet Tende connection between the grounding cable and the carrier element and thus between the grounding cable and the outer conductor of the coaxial cable can be established. WO 02/061884 AI a device of the type mentioned in the preamble of claim 1 is known. In the device known from this publication, the connection means have a connection element designed in the manner of a cable lug, which is firmly and electrically conductively connected to the carrier element or to a part which is electrically conductively connected to the latter. The device known from the publication is simple and inexpensive to produce and enables an electrically conductive connection to be made quickly and easily between the carrier element of the device and an electrically conductive component, for example an earth cable. The invention has for its object to provide a device of the type mentioned in the preamble of claim 1, which is even easier and therefore cheaper to manufacture. The invention frees itself from the idea of, for example, establishing a grounding of a stripped outer conductor of a coaxial cable by connecting this electrically conductive component, for example a metal part of a mast of a mobile radio transmission system, to the carrier element of the device via a grounding cable. Rather, it is based on the idea of designing the device according to the invention in such a way that the carrier element can also be connected to the electrically conductive component without an earth cable. For this purpose, the teaching according to the invention provides that the connection element is designed in the form of a strip and at least in a flat cross-section in an area extending from its free end to a connection point with the base body. According to the invention, the flat, strip-shaped connecting element is connected directly to the electrically conductive component, for example a metal part of a mast of a mobile radio transmitter system. In this way it is possible to do without a grounding cable, for example to ground a stripped outer conductor of a coaxial cable. The connection of the connection element to the electrically conductive component can be a detachable connection, for example a screw connection, or an inseparable connection, for example a welded or soldered connection. The device according to the invention is particularly simple and therefore inexpensive to manufacture and particularly easy to handle. In principle, the connection element can be essentially rigid. An advantageous development provides that the connection element is flexible. In this way, the handling of the device according to the invention is further simplified because the End element can be brought into a desired position for connection to the electrically conductive component by bending. In the aforementioned embodiment, the connection element is expediently essentially planar in the x-bent state. If the connection between the connection element and the electrically conductive component, for example a metal part of a mast of a mobile radio transmission system, is a detachable connection, it is advantageous for the connection element to have at least one recess, preferably a bore, for the passage a screw or the like for establishing an electrically conductive connection between the connection element and the electrically conductive component. In this way, the connection of the connection element with the electrically conductive component is made considerably easier and is time-saving. In principle, the connection element can be designed as a separate component, which is held, for example, by clamping between the support elements and a reinforcing element connected to the support element. A particularly simple and inexpensive to manufacture and particularly easy to handle embodiment provides that the connection element is formed in one piece with the carrier element or a reinforcing element that is electrically conductive with the carrier element. Another advantageous development of the teaching according to the invention provides that the connection element has an essentially constant cross-section along its extension in plan view. Further advantageous developments of the teaching according to the invention are contained in the subclaims. The invention is explained in more detail below with reference to the accompanying drawing, which represents an exemplary embodiment.

Es wird auf die Figuren 1-4 Bezug genommen. In Fig. 1 ist ein Ausführungsbeispiel einer erfindungsgemäßen Einrichtung 2 dargestellt, die einen als Schelle ausgebildeten, biegsamen Grundkörper 4 aufweist, der bei diesem Ausfuhrungsbeispiel einteilig und in Umfangsrichtung offen ausgebildet ist und an seinen freien Enden abgewinkelte Laschen 6 , 8 auf eist , die in Montageposition in weiter unten näher erläuterter Weise durch in Fig. 1 nicht dargestellte Schrauben miteinander verbindbar sind. Der Grundkörper 4 weist ein bandförmiges Trägerelement 10 aus Metall sowie ein Teil 12 aus elastischem Material, bei diesem Ausführungsbeispiel ein Elastomer, auf, in das das Trägerelement 10 mit seinen axialen Rändern eingebettet und so mit dem Teil 12 aus elasti- schem Material verbunden ist (Fig. 3) . Das Trägerelement 10 erstreckt sich bis in die Laschen 6, 8 und ist in diesem Bereich zur Stabilisierung mit Verstärkungselementen 5, 7 aus Metall -verstärkt, die beispielsweise mit dem Trägerelement 10 verschweißt sein können. In der Lasche 6 sind Gewindebohrungen 9, 11 und in der Lasche 8 Durchgangsbohrungen 13, 15 gebildet, die in weiter unten näher erläuterter Weise zur Aufnahme von in Fig. 1 nicht dargestellten Schrauben dienen, mittels derer die Laschen 6, 8 in I ontageposition miteinander verspannbar sind. Zum Anschließen eines elektrisch leitfähigen Bauteiles, beispielsweise eines Metallteiles eines Sendemastes einer Mobilfunk-Sendeanlage, an das Trägerelement 10 sind Anschlußmittel vorgesehen, die zur Her- Stellung einer elektrisch leitfähigen Verbindung zwischen dem Trägerelement und einem Verbindungspunkte, beispielsweise einem Erdungskontakt, ausgebildet sind. Die Anschlußmittel sind aus einem Anschlußelement 20 gebildet, das aus einem Streifen eines elektrisch leit- fähigen und biegbaren Material gefertigt ist, wie beispielsweise ein Metallstreifen, dessen Länge wesentlich größer als seine Breite ist, wobei seine Abmessungen in der Breite wesentlich größer als die Dicke des Metallstreifens ist. Das Anschlußelement 20 ist an seinem einen Ende mit Bohrungen versehen, so daß es zwischen den Laschen des Grundkörpers verklemmt werden kann, wobei durch die Bohrungen die Schrauben zur Verbindung der Schelle durchgeführt werden, so daß eine einfache, aber sichere elektrische Verbindung zwischen dem Trägerelement und dem Anschlußelement 20 hergestellt ist. An seinem gegenüberliegenden Ende ist das Anschlußelement 20 derart ausgebildet, daß ein Erdungskontakt hergestellt werden kann. Hierzu weist dieses Ende des Anschlußelementes 20 ebenfalls eine Bohrung auf, die es erlaubt, durch Einsetzen einer Schraube oder eines anderen Befestigungsmittels einen elektrischen Kontakt zu Erdungszwecken herzustellen. Im folgenden wird das Herstellen einer elektrisch leitenden Verbindung zwischen einem abschnittsweise absiolierten A-ußenleiter eines Koaxialkabels und eines Erdungskontaktes erläutert. In einem ersten Schritt wird der als Schelle aus- gebildete, biegsame Grundkörper 4 um den abisoliertenReference is made to Figures 1-4. In Fig. 1 an embodiment of a device 2 according to the invention is shown, which has a flexible base body 4 designed as a clamp, which in this embodiment is formed in one piece and open in the circumferential direction and at its free ends angled tabs 6, 8 on ice, which can be connected to one another in the mounting position in a manner explained in more detail below by means of screws (not shown in FIG. 1). The base body 4 has a band-shaped carrier element 10 made of metal and a part 12 made of elastic material, in this exemplary embodiment an elastomer, in which the carrier element 10 is embedded with its axial edges and is thus connected to the part 12 made of elastic material ( Fig. 3). The carrier element 10 extends into the tabs 6, 8 and is reinforced in this area for stabilization with reinforcing elements 5, 7 made of metal, which can be welded to the carrier element 10, for example. In the tab 6 threaded holes 9, 11 and in the tab 8 through holes 13, 15 are formed, which serve in a manner explained in more detail below for receiving screws, not shown in Fig. 1, by means of which the tabs 6, 8 in I ontageposition with each other are braced. To connect an electrically conductive component, for example a metal part of a mast of a mobile radio transmission system, to the carrier element 10, connection means are provided which are designed to establish an electrically conductive connection between the carrier element and a connection point, for example an earth contact. The connection means are formed from a connection element 20, which is made of a strip of an electrically conductive and bendable material, such as a metal strip, the length of which is substantially greater than its width, its dimensions in width being substantially greater than the thickness of the Metal strip. The connecting element 20 is provided at one end with holes so that it can be clamped between the tabs of the base body, the screws for connecting the clamp being carried out through the holes, so that a simple but secure electrical connection between the support element and the connecting element 20 is made. At its opposite end, the connection element 20 is designed such that an earth contact can be made. For this purpose, this end of the connecting element 20 likewise has a bore which makes it possible to make an electrical contact for grounding purposes by inserting a screw or another fastening means. In the following, the establishment of an electrically conductive connection between a stripped stripped outer conductor of a coaxial cable and a grounding contact is explained. In a first step, the flexible base body 4, which is designed as a clamp, is stripped around the stripped

In einem zweiten Schritt werden Schrauben in die Durchgangsbohrungen 13, 15 der Lasche 8 eingesetzt.Section of the outer conductor placed so that the band-shaped carrier element 10 made of metal encompasses the stripped section of the outer conductor. In a second step, screws are inserted into the through bores 13, 15 of the tab 8.
Bevor die beiden Laschen 6 und 8 des biegsamen Grundkörpers zusammengedrückt werden, um die in den Durchgangsbohrungen 13, 15 befindlichen Schrauben in die Gewindebohrungen 9, 11 der Lasche 6 einschrauben zu können, wird das erste Ende des Anschlußelementes 20 zwischen den Laschen 6 und 8 so plaziert, daß die in die Durchgangsbohrungen 13, 15 eingesetzten Schrauben durch die Durchführung des Anschlußelementes 20 hindurchgreifen, so daß die eingesetzten Schrauben in Ge- windebohrungen 9, 11 der Lasche 6 eingeschraubt werden können, wobei dies Verschrauben ein Verspannen des biegsamen Grundkörpers 4 bewirkt, so daß das Trägerelement 10 an den abisolierten Abschnitt des Außenlei- ters angedrückt wird, so daß ein elektrischer Kontakt zwischen dem abisolierten Außenleiter eines Koaxialkabels und dem Trägerelement 10 gewährleistet ist. Zugleich wird zwischen den beiden Laschen 6 und 8 das Anschlußelement 20 eingepreßt, so daß zwischen dem An- Schlußelement 20 und den Laschen 6 und 8 ein elektrischer Kontakt gewährleistet ist, so daß zwischen dem Anschlußelement 20 und dem Trägerelement 10 eine elektrisch leitfähige Verbindung gegeben ist. Um eine elektrische Verbindung mit dem Erdungs- kabel herzustellen, kann das Anschlußelement 20 entsprechend der Position des Erdungskontaktes verbogen werden und mit einer in die Bohrung an dem anderen Ende des Anschlußelementes 20 durch Einsatz einer Schraube oder eines anderen Verbindungsmittels ein elektrischer Kontakt hergestellt werden, so daß eine elektrischeBefore the two tabs 6 and 8 of the flexible base body are pressed together so that the screws located in the through bores 13, 15 can be screwed into the threaded bores 9, 11 of the tab 6, the first end of the connecting element 20 between the tabs 6 and 8 is so placed that the screws inserted into the through holes 13, 15 reach through the passage of the connecting element 20 so that the screws used in Wind holes 9, 11 of the tab 6 can be screwed in, this screwing causes a tensioning of the flexible base body 4, so that the carrier element 10 is pressed against the stripped section of the outer conductor, so that an electrical contact between the stripped outer conductor of a coaxial cable and the carrier element 10 is guaranteed. At the same time, the connecting element 20 is pressed in between the two lugs 6 and 8, so that an electrical contact is ensured between the connecting element 20 and the lugs 6 and 8, so that an electrically conductive connection is provided between the connecting element 20 and the carrier element 10 , In order to establish an electrical connection with the grounding cable, the connecting element 20 can be bent in accordance with the position of the grounding contact and an electrical contact can be made with one in the bore at the other end of the connecting element 20 by using a screw or other connecting means that an electrical
Verbindung zwischen dem abisolierten Abschnitt eines Außenleiters eines Koaxialkabels und einem Erdungskontakt gegeben ist . Die Ausbildung der Einrichtung im übrigen, ihre Montage sowie ihre Funktion sind dem Fachmann allgemein bekannt, beispielsweise durch WO 02/061884 AI, deren Inhalt hiermit durch Bezugnahme in die vorliegende Anmeldung aufgenommen ist, und werden daher hier nicht näher erläutert . Eine besonders vorteilhafte Weiterbildung des oben beschriebenen Ausführungsbeispieles besteht darin, das Anschlußelement 20 nicht als separates Bauteil, sondern einstückig mit einem der Verstärkungselemente 5, 7 auszubilden. Bei dieser Ausführungsform ist die Herstel- lung noch einfacher und damit kostengünstiger gestaltet. Es wird auf die Figuren 5 und 6 Bezug genommen. Die Figuren 5 und 6 zeigen ein zweites Aus- führungsbeispiel des Anschlußelementes 20, das einstük- kig mit dem Verstärkungselement 5 ausgebildet ist, mit dem es elektrisch leitend verbunden ist. Ebenfalls ist diese zweite Ausführungsform des Anschlußelementes 20 mit einer Bohrung versehen, so daß durch Einsetzen ei- ner Schraube oder eines anderen Befestigungsmittels ein elektrischer Kontakt zu Erdungszwecken hergestellt werden kann. Das Anschlußelement 20 ist zu dem Verstärkungselement 5 in einem Winkel von 45 Grad angeordnet, so daß nach dem Umspannen eines zu kontaktierenden Koa- xialkabels mit dem als Schelle ausgebildeten Grundkörper die Herstellung eines Erdungskontaktes vereinfacht wird. Connection between the stripped portion of an outer conductor of a coaxial cable and a ground contact is given. The design of the device for the rest, its assembly and its function are generally known to the person skilled in the art, for example from WO 02/061884 AI, the content of which is hereby incorporated by reference into the present application, and are therefore not explained in more detail here. A particularly advantageous development of the exemplary embodiment described above consists in designing the connecting element 20 not as a separate component, but in one piece with one of the reinforcing elements 5, 7. In this embodiment, the manufac tion even simpler and therefore more cost-effective. Reference is made to FIGS. 5 and 6. FIGS. 5 and 6 show a second exemplary embodiment of the connecting element 20, which is formed in one piece with the reinforcing element 5, to which it is connected in an electrically conductive manner. This second embodiment of the connection element 20 is likewise provided with a bore so that an electrical contact can be made for grounding purposes by inserting a screw or other fastening means. The connecting element 20 is arranged at an angle of 45 degrees to the reinforcing element 5, so that after a coaxial cable to be contacted has been reclamped with the base body designed as a clamp, the production of an earth contact is simplified.
