Description

Die Erfindung betrifft eine Einrichtung der im Oberbegriff des Anspruchs 1 genannten Art zum elektrisch leitenden Kontaktieren eines abisolierten Außenleiters eines Koaxialkabels.The invention relates to a device of the type mentioned in the preamble of claim 1 for the electrically conductive contact of a stripped outer conductor of a coaxial cable.

Durch EP 0 744 788 A1 ist eine Einrichtung der betreffenden Art bekannt, die einen als um das zu kontaktierende Kabel spannbare Schelle ausgebildeten Grundkörper aufweist, der in Umfangsrichtung offen ausgebildet ist und an seinen Enden abgewinkelte Laschen aufweist, an deren in Montageposition einander zugewandten Flächen Dichtflächen aus elastischem Material gebildet sind, wobei die Laschen in Montageposition der Einrichtung mittels Schrauben miteinander verbindbar sind. Bei der bekannten Einrichtung weist der Grundkörper eine bandförmige metallische Schelle auf, die in elastisches Material eingebettet ist, wobei an der in Montageposition dem zu kontaktierenden Körper zugewandten Seite eine Kontaktfläche für ein Kontaktelement zur Kontaktiereung des abisolierten Bereiches des Koaxialkabels freigelassen ist.A device of the type in question is known from EP 0 744 788 A1, which has a base body designed as a clamp that can be tensioned around the cable to be contacted, which is designed to be open in the circumferential direction and has angled tabs at its ends, with sealing surfaces on their surfaces facing one another in the assembly position are made of elastic material, wherein the tabs can be connected to each other in the mounting position of the device by means of screws. In the known device, the base body has a band-shaped metallic clamp which is embedded in elastic material, a contact surface for a contact element for contacting the stripped region of the coaxial cable being left free on the side facing the body to be contacted in the assembly position.

Nachteilig bei der bekannten Einrichtung ist, daß dann, wenn beim Montieren der Einrichtung an dem Koaxialkabel die Schrauben zum Spannen des Grundkörpers mit übermäßiger Kraft angezogen werden, das elastische Material der Dichtflächen an den Laschen übermäßig und nicht definiert zusammengedrückt wird, so daß die Gefahr besteht, daß das elastische Material beschädigt wird und die Dichtflächen hierdurch ihre Dichtwirkung verlieren.A disadvantage of the known device is that when the device is mounted on the coaxial cable, the screws for tensioning the base body Excessive force are tightened, the elastic material of the sealing surfaces on the tabs is compressed excessively and not defined, so that there is a risk that the elastic material is damaged and the sealing surfaces thereby lose their sealing effect.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der im Oberbegriff des Anspruchs 1 genannten Art anzugeben, die den Nachteil der bekannten Einrichtung nicht aufweist, bei der also die Gefahr, daß beim Anziehen der Schrauben das elastische Material der Dichtflächen übermäßig zusammengedrückt wird, verringert ist.The invention has for its object to provide a device of the type mentioned in the preamble of claim 1, which does not have the disadvantage of the known device, in which the risk that the elastic material of the sealing surfaces is excessively compressed when tightening the screws is reduced ,

Diese Aufgabe wird durch die im Anspruch 1 angegebene Lehre gelöst.This object is achieved by the teaching specified in claim 1.

Der Grundgedanke der erfindungsgemäßen Lehre besteht darin, Mittel zur Begrenzung des Einschraubweges der Schraube vorzusehen, derart, daß eine Zusammendrükkung des elastischen Materials der Dichtflächen beim Anziehen der Schraube definiert erfolgt. Auf diese Weise ist zuverlässig verhindert, daß das elastische Material der Dichtflächen beim Anziehen der Schraube übermäßig zusammengedrückt und hierbei möglicherweise beschädigt wird. Die Zusammendrückung des elastischen Materiales erfolgt vielmehr definiert, wobei das Maß der Zusammendrückung in einfacher Weise durch entsprechende Dimensionierung der Mittel zur Begrenzung des Einschraubweges und damit des maximal möglichen Einschraubweges wählbar ist.The basic idea of the teaching according to the invention is to provide means for limiting the screwing-in path of the screw in such a way that the elastic material of the sealing surfaces is compressed in a defined manner when the screw is tightened. In this way, the elastic material of the sealing surfaces is reliably prevented from being excessively compressed when the screw is tightened and possibly being damaged in the process. Rather, the compression of the elastic material takes place in a defined manner, the degree of compression being selectable in a simple manner by appropriately dimensioning the means for limiting the screw-in path and thus the maximum possible screw-in path.

Aufgrund der erfindungsgemäß vorgesehenen Mittel zur Begrenzung des Einschraubweges ist die Montage der erfindungsgemäßen Einrichtung vereinfacht und damit auch von ungeübtem Personal ohne weiteres durchführbar.Due to the means provided according to the invention for limiting the screwing-in path, the installation of the device according to the invention is simplified and can therefore also be carried out easily by untrained personnel.

Die erfindungsgemäße Einrichtung ist einfach und damit kostengünstig herstellbar und robust im Aufbau.The device according to the invention is simple and thus inexpensive to manufacture and robust in construction.

Die Mittel zur Begrenzung des Einschraubweges können entsprechend den jeweiligen Anforderungen in beliebiger geeigneter Weise ausgebildet sein, beispielsweise dadurch, daß das Gewinde der Schraube mit axialem Abstand zu ihrem Kopf endet, so daß der Einschraubweg durch die Länge des Gewindes begrenzt ist.The means for limiting the screw-in path can be designed in any suitable manner according to the respective requirements, for example in that the thread of the screw ends at an axial distance from its head, so that the screw-in path is limited by the length of the thread.

Eine außerordentlich vorteilhafte Weiterbildung des Grundgedankens der erfindungsgemäßen Lehre sieht vor, daß die Mittel zur Begrenzung des Einschraubweges durch einen Anschlag gebildet sind. Diese Ausführungsform ermöglicht auf besonders einfache Weise eine Begrenzung des Einschraubweges.An extremely advantageous development of the basic idea of the teaching according to the invention provides that the means for limiting the screwing-in path are formed by a stop. This embodiment enables the screw-in path to be limited in a particularly simple manner.

Entsprechend den jeweiligen Anforderungen kann der Anschlag an der Schraube angeordnet, insbesondere an die Schraube angeformt sein, oder es kann der Anschlag an einer der Laschen angeordnet, insbesondere an einer der Laschen angeformt sein. Bei den Ausführungsformen, bei denen der Anschlag an die Schraube oder an eine der Laschen angeformt ist, ist ein zusätzliches Bauteil zur Bildung des Anschlages nicht erforderlich, so daß der Aufbau der erfindungsgemäßen Einrichtung weiter vereinfacht und kostengünstiger gestaltet ist.According to the respective requirements, the stop can be arranged on the screw, in particular molded onto the screw, or the stop can be arranged on one of the tabs, in particular molded onto one of the tabs. In the embodiments in which the stop is integrally formed on the screw or on one of the tabs, an additional component is not required to form the stop, so that the structure of the device according to the invention is further simplified and less expensive.

Eine Weiterbildung der Ausführungsform mit dem an eine der Laschen angeformten Anschlag sieht vor, daß der Anschlag durch wenigstens einen sich in Axialrichtung der Schraube erstreckenden, an der in Montageposition dem Kopf der Schraube zugewandten Seite einer Lasche angeordneten Vorsprung gebildet ist, derart, daß der Kopf der Schraube am Ende des Einschraubweges an dem Vorsprung zur Anlage gelangt. Bei dieser Ausführungsform kann der Vorsprung beispielsweise durch wenigstens eine an der Lasche ausgebildete Nase oder dergleichen gebildet sein.A further development of the embodiment with the stop molded onto one of the tabs provides that the stop is formed by at least one projection which extends in the axial direction of the screw and which is arranged on the side of a tab facing the head of the screw in the mounting position, such that the head the screw comes to rest on the projection at the end of the screw-in path. In this embodiment, the projection can be formed, for example, by at least one nose or the like formed on the tab.

Eine andere Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß der Anschlag durch eine den Schaft der Schraube umgebende Scheibe oder Hülse gebildet ist, die in Montageposition zwischen dem Kopf der Schraube und der zugewandten Lasche angeordnet ist. Diese Ausführungsform hat den Vorteil, daß sowohl für die Schraube als auch für die den Anschlag bildende Scheibe Standardbauteile verwendet werden können, so daß die erfindungsgemäße Einrichtung auch bei dieser Ausführungsform besonders einfach und damit kostengünstig herstellbar gestaltet ist.Another development of the teaching according to the invention provides that the stop is formed by a disk or sleeve surrounding the shaft of the screw, which is arranged in the assembly position between the head of the screw and the facing tab. This embodiment has the advantage that standard components can be used both for the screw and for the washer forming the stop, so that the device according to the invention is also designed to be particularly simple and therefore inexpensive to manufacture in this embodiment.

Zweckmäßigerweise erstreckt sich die Schraube in Montageposition der Einrichtung durch eine Durchgangsbohrung, die in einer der Laschen gebildet ist, und ist in eine Gewindebohrung eingeschraubt, die in der anderen Lasche gebildet ist.The screw expediently extends in the assembly position of the device through a through hole which is formed in one of the tabs and is screwed into a threaded hole which is formed in the other tab.

Besteht der Grundkörper der erfindungsgemäßen Einrichtung beispielsweise aus dünnem Blech, so ist es zur Erhöhung der Stabilität und zur Erzielung einer ausreichenden Tiefe insbesondere der Gewindebohrung zweckmäßig, daß die Laschen Verstärkungselemente, vorzugsweise aus Metall aufweisen, in denen die Bohrungen gebildet sind.If the base body of the device according to the invention consists of thin sheet metal, for example, in order to increase the stability and to achieve a sufficient depth, in particular the threaded bore, it is expedient that the tabs have reinforcing elements, preferably made of metal, in which the bores are formed.

Eine Weiterbildung der Ausführungsform, bei der der Anschlag an die Schraube angeformt ist, sieht vor, daß die Schraube zwischen ihrem Kopf und ihrem mit einem Gewinde versehenen Ende einen gewindefreien Bereich aufweist, dessen Durchmesser größer als der Durchmesser des Gewindes ist, derart, daß eine Schulter gebildet ist, wobei der Durchmesser der Durchgangsbohrung in der Lasche dem Durchmesser der Schraube im Bereich der Schulter entspricht oder größer ist als dieser, derart, daß die axiale Stirnfläche der Schulter in Einschraublage an der dieser Lasche zugewandten Fläche der anderen Lasche anliegt.A further development of the embodiment in which the stop is molded onto the screw provides that the screw has a thread-free area between its head and its threaded end, the diameter of which is larger than the diameter of the thread, such that a Shoulder is formed, wherein the diameter of the through hole in the tab corresponds to the diameter of the screw in the region of the shoulder or is greater than this, such that the axial end face of the shoulder in the screw-in position on the surface of the other facing this tab Tab rests.

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 diesen, mittels derer die Laschen 6,8 in Montageposition miteinander verbindbar sind.The base body 4 has a band-shaped metal part 10 and a part 12 made of elastic material, in the exemplary embodiment an elastomer, in which the metal part 10 is embedded with its axial edges and is thus connected to the part 12 made of elastic material (FIG. 4) , The metal part 10 extends in the circumferential direction into the tabs 6, 8 and is reinforced in this area for stabilization with plate-shaped reinforcing elements 5, 7 made of metal, which can be welded to the metal part 10, for example. In the tab 6 threaded holes 9, 11 and in the tab 8 through holes 13, 15 are formed, which in a manner explained in more detail below for receiving screws not shown in FIG. 1, by means of which the tabs 6, 8 can be connected to one another in the assembly position are.

Aus Fig. 1 ist nicht ersichtlich und deshalb wird hier erläutert, daß die in Montageposition einander zugewandten Flächen der Laschen 6, 8 mit einem elastischen Material, beispielsweise einem Elastomer, versehen sind, so daß Dichtflächen gebildet sind, die in Montageposition der Einrichtung 2 dichtend aneinander anliegen.From Fig. 1 is not apparent and is therefore explained here that the mutually facing surfaces of the tabs 6, 8 in the mounting position are provided with an elastic material, for example an elastomer, so that sealing surfaces are formed, the sealing in the mounting position of the device 2 together issue.

Das Teil 12 aus elastischem Material bildet an der in Montageposition einem zu kontaktierenden Koaxialkabel zugewandten Seite Dichtlippen 14, 16 sowie bei diesem Ausführungsbeispiel jeweils in Axialrichtung außen von den Dichtlippen 14, 16 weitere Dichtlippen 18, 20. In Montageposition liegt der Grundkörper 4 mit den Dichtlippen 14, 16 sowie den weiteren Dichtlippen 18, 20 dichtend an einer Außenfläche des zu kontaktierenden Körpers an, so daß ein in Montageposition zwischen dem zu kontaktierenden Körper und dem Grundkörper 4 gebildeter Raum gegen ein Eindringen von Luft und/oder Feuchtigkeit abgedichtet ist.The part 12 made of elastic material forms sealing lips 14, 16 on the side facing a coaxial cable to be contacted in the mounting position and, in this exemplary embodiment, in the axial direction outside of the sealing lips 14, 16 further sealing lips 18, 20. In the mounting position, the base body 4 lies with the sealing lips 14, 16 and the further sealing lips 18, 20 sealingly on an outer surface of the body to be contacted, so that a space formed in the assembly position between the body to be contacted and the base body 4 is sealed against the ingress of air and / or moisture.

Die Einrichtung 2 weist ferner ein in Fig. 1 nicht dargestelltes Kontaktelement zur Herstellung einer elektrisch leitenden Verbindung mit dem zu kontaktierenden Koaxialkabel auf, das in Montageposition an der dem zu kontaktierenden Koaxialkabel zugewandten Seite des Grundkörpers, bei dem Ausführungsbeispiel gemäß Fig. 1 also an einer radialen Innenfläche 22 des Grundkörpers 4, die eine Haltefläche bildet, gehalten ist, beispielsweise mittels Klebstoffes.The device 2 also has a contact element (not shown in FIG. 1) for establishing an electrically conductive connection with the coaxial cable to be contacted, which in the assembly position on the side of the base body facing the coaxial cable to be contacted, in the exemplary embodiment according to FIG. 1 on one radial inner surface 22 of the base body 4, which forms a holding surface, is held, for example by means of adhesive.

Die Einrichtung 2 weist ferner zur Justierung des Kontaktelementes bei der Herstellung der Einrichtung 2 Justierhilfsmittel für das Kontaktelement auf, die bei diesem Ausführungsbeispiel durch Anlagekanten 28, 30, 32 gebildet sind, die an Stegen 34, 36, 38 gebildet sind, die an die Dichtlippen 14, 16 des Teiles 12 aus elastischem Material angeformt sind.The device 2 also has adjustment aids for the contact element for adjusting the contact element in the manufacture of the device 2, which are formed in this embodiment by contact edges 28, 30, 32, which are formed on webs 34, 36, 38, which on the sealing lips 14, 16 of the part 12 are formed from elastic material.

Die Stege 34, 36 erstrecken sich von dem axialen Rand 26 des Grundkörpers 4 in Axialrichtung nach innen, während sich der Steg 38 von dem gegenüberliegenden axialen Rand 26 in Axialrichtung nach innen erstreckt, wobei die Stege 34, 36 auf einer Umfangslinie 33 angeordnet sind und der Steg 38 auf einer zu der Umfangslinie 33 axial versetzten Umfangslinie 35 angeordnet ist.The webs 34, 36 extend inward from the axial edge 26 of the base body 4 in the axial direction, while the web 38 extends inward in the axial direction from the opposite axial edge 26, the webs 34, 36 being arranged on a circumferential line 33 are and the web 38 is arranged on a circumferential line 35 axially offset from the circumferential line 33.

Fig. 2 zeigt eine Ansicht auf die radiale Innenfläche 22 der Einrichtung 2.2 shows a view of the radial inner surface 22 of the device 2.

Fig. 3 zeigt die Einrichtung 2 mit einem daran gehaltenen Kontaktelement 40, das bei diesem Ausführungsbeispiel aus elektrisch leitfähigem Graphit besteht und in der Draufsicht im wesentlichen rechteckförmig ausgebildet ist. Das Kontaktelement 40 ist durch Klebstoff mit der radialen Innenfläche 22 des Grundkörpers 4 verbunden und so an diesem gehalten.FIG. 3 shows the device 2 with a contact element 40 held thereon, which in this exemplary embodiment consists of electrically conductive graphite and is essentially rectangular in plan view. The contact element 40 is connected to the radial inner surface 22 of the base body 4 by adhesive and thus held thereon.

Aus Fig. 3 ist ersichtlich, daß das Kontaktelement 40 in der dort dargestellten Befestigungslage mit gegenüberliegenden Bereichen seines Randes an den Anlagekanten 28, 30, 32 der Stege 34, 36, 38 anliegt, die Zentriermittel zum Zentrieren des Kontaktelementes 40 zwischen den gegenüberliegenden axialen Rändern 24, 26 des Grundkörpers 4 bilden. Durch die Anlagekanten 28, 30, 32 ist sichergestellt, daß sich das Kontaktelement 40 in der gewünschten Lage, in der seine Längsseiten im wesentlichen parallel zu den axialen Rändern 24, 26 des Grundkörpers 4 verlaufen, an dem Grundkörper 4 gehalten ist und nicht seitlich übersteht.From Fig. 3 it can be seen that the contact element 40 is in the fastening position shown there with opposite regions of its edge on the contact edges 28, 30, 32 of the webs 34, 36, 38, the centering means for centering the contact element 40 between the opposite axial edges 24, 26 of the base body 4 form. The contact edges 28, 30, 32 ensure that the contact element 40 is held on the base body 4 in the desired position, in which its longitudinal sides run essentially parallel to the axial edges 24, 26 of the base body 4, and does not protrude laterally ,

Fig. 4 zeigt einen Schnitt entlang einer Linie IV-IV in Fig. 3, wobei die Einrichtung 2 in Montageposition dargestellt ist, in der der Grundkörper 4 mit den Dichtlippen 14, 16 und den weiteren Dichtlippen 18, 20 an einem zu kontaktierenden Koaxialkabel 42, anliegt. Zur Kontaktierung eines abschnittsweise abisolierten Außenleiters 44 des Koaxialkabels 42 in einem Kontaktbereich 46 steht das Kontaktelement 40 in Radialrichtung zu dem Koaxialkabel 42 hin so weit vor, daß es bei an einer Ummantelung 48 des Koaxialkabels 42 anliegenden Dichtlippen 14, 16 bzw. 18, 20 an dem in Radialrichtung zurückspringenden, abisolierten Außenleiter 44 anliegt und so eine elektrisch leitende Verbindung zu diesem herstellt.FIG. 4 shows a section along a line IV-IV in FIG. 3, the device 2 being shown in the assembly position in which the base body 4 with the sealing lips 14, 16 and the further sealing lips 18, 20 on a coaxial cable 42 to be contacted , is present. For contacting a stripped outer conductor 44 of the coaxial cable 42 in a contact area 46, the contact element 40 projects so far in the radial direction towards the coaxial cable 42 that it bears against a sheath 48 of the coaxial cable 42 Sealing lips 14, 16 and 18, 20 abut against the stripped outer conductor 44, which springs back in the radial direction and thus establishes an electrically conductive connection to the latter.

Fig. 5 zeigt die Einrichtung 2 gemäß Fig. 1 in Montageposition, in der der Grundkörper 4 das zu kontaktierende Koaxialkabel 42 muffenförmig umgreift. Zur Befestigung der Einrichtung 2 an dem Koaxialkabel 42 wird zunächst das Koaxialkabel in einem axialen Abschnitt abisoliert und daran anschließend der als Schelle ausgebildete Grundkörper 4 um das zu kontaktierende Koaxialkabel 42 herum mittels Schrauben 50, 52 aus Metall gespannt, die sich durch die in der Lasche 8 gebildeten Durchgangsbohrungen 13, 15 erstrecken und in die in der Lasche 6 gebildeten Gewindebohrungen 9, 11 eingreifen.FIG. 5 shows the device 2 according to FIG. 1 in the assembly position, in which the base body 4 encompasses the coaxial cable 42 to be contacted in a sleeve-like manner. To fasten the device 2 to the coaxial cable 42, the coaxial cable is first stripped in an axial section and then the base body 4, which is designed as a clamp, is tensioned around the coaxial cable 42 to be contacted by means of screws 50, 52 made of metal, which pass through the tab 8 through holes 13, 15 extend and engage in the threaded holes 9, 11 formed in the tab 6.

Beim Spannen des Grundkörpers 4 gelangen die Dichtlippen 14, 16 und die weiteren Dichtlippen 18, 20 dichtend an der Ummantelung 48 des Koaxialkabels 42 zur Anlage, so daß sie den in Montageposition zwischen dem Koaxialkabel 42 und dem Grundkörper 4 gebildeten Raum gegen ein Eindringen von Luft und/oder Feuchtigkeit abdichten. In Umfangsrichtung des Grundkörpers 4 ist dieser Raum dadurch abgedichtet, daß die an den Laschen 6, 8 gebildeten Dichtflächen dichtend aneinander zur Anlage gelangen, wobei das elastische Material der Dichtflächen zusammengedrückt wird.When tensioning the base body 4, the sealing lips 14, 16 and the further sealing lips 18, 20 sealingly come into contact with the casing 48 of the coaxial cable 42, so that they protect the space formed in the assembly position between the coaxial cable 42 and the base body 4 against the ingress of air and / or seal moisture. In the circumferential direction of the base body 4, this space is sealed in that the sealing surfaces formed on the brackets 6, 8 come to bear against one another in a sealing manner, the elastic material of the sealing surfaces being compressed.

Beim Spannen des Grundkörpers 4 gelangt ferner das Kontaktelement 40 an dem abisolierten Außenleiter 44 des Koaxialkabels 42 zur Anlage, so daß über das Kontaktelement 40 eine elektrisch leitende Verbindung zwischen dem Außenleiter 44 und dem Metallteil 10 des Grundkörpers 4 hergestellt ist. Da sich das Metallteil 10 bis in die Laschen 6, 8 erstreckt, ist mittels der Schrauben 50, 52 eine elektrisch leitende Verbindung zu einem Leiter, beispielsweise einem in Fig. 5 schematisch angedeuteten Erdungskabel 54, herstellbar. Hierzu kann das Erdungskabel 54 mittels einer Anschlußöse mit der Schraube 50 verbunden sein. Es ist somit in der gewünschten Weise eine elektrisch leitende Verbindung zwischen dem Erdungskabel 54 und dem Außenleiter 44 des Koaxialkabels 42 hergestellt, so daß dieser Außenleiter 44 geerdet ist.When tensioning the base body 4, the contact element 40 also comes into contact with the stripped outer conductor 44 of the coaxial cable 42, so that an electrically conductive connection between the outer conductor 44 and the metal part 10 of the base body 4 is established via the contact element 40. Since the metal part 10 extends into the tabs 6, 8, the Screws 50, 52 can be used to produce an electrically conductive connection to a conductor, for example an earthing cable 54, which is indicated schematically in FIG. 5. For this purpose, the grounding cable 54 can be connected to the screw 50 by means of a connection eyelet. An electrically conductive connection between the grounding cable 54 and the outer conductor 44 of the coaxial cable 42 is thus established in the desired manner, so that this outer conductor 44 is grounded.

Um beim Spannen der Schrauben 50, 52 ein übermäßiges Zusammendrücken des elastischen Materiales der Dichtflächen zu vermeiden, sind erfindungsgemäß Mittel zur Begrenzung des Einschraubweges der Schrauben 50, 52 vorgesehen, was nachfolgend anhand von Fig. 6 näher erläutert wird.In order to avoid excessive compression of the elastic material of the sealing surfaces when the screws 50, 52 are tightened, means for limiting the screwing-in path of the screws 50, 52 are provided according to the invention, which is explained in more detail below with reference to FIG. 6.

Fig. 6 zeigt stark schematisiert einen Radialschnitt durch die Einrichtung 2 in Montageposition im Bereich der Schraube 52, wobei aus Gründen der Vereinfachung lediglich das Metallteil 10, die Verstärkungselemente 5, 7 und die Schraube 52 dargestellt, die übrigen Teile der Einrichtung 2 jedoch weggelassen sind. Aus Gründen der Veranschaulichung ist die Dicke der Verstärkungselemente 5, 7 überhöht dargestellt.6 shows a highly schematic radial section through the device 2 in the mounting position in the area of the screw 52, only the metal part 10, the reinforcing elements 5, 7 and the screw 52 being shown for the sake of simplicity, but the remaining parts of the device 2 have been omitted , For reasons of illustration, the thickness of the reinforcing elements 5, 7 is shown exaggerated.

Wie aus Fig 6 ersichtlich ist, weist die Schraube 52 in Axialrichtung zwischen ihrem Kopf 56 und ihrem mit Gewinde versehenen Ende 58 einen gewindefreien Bereich 60 auf, dessen Durchmesser größer als der Durchmesser des Gewindes ist, derart, daß in Einschraubrichtung vorne an dem Bereich 60 eine Schulter 61 gebildet ist. Die in Fig. 6 nicht erkennbare Schraube 50 ist entsprechend ausgebildet.As can be seen from FIG. 6, the screw 52 has an unthreaded region 60 in the axial direction between its head 56 and its threaded end 58, the diameter of which is larger than the diameter of the thread, in such a way that in the screwing direction at the front on the region 60 a shoulder 61 is formed. The screw 50, which cannot be seen in FIG. 6, is designed accordingly.

Der Durchmesser der Durchgangsbohrung 13 in der Lasche 8 ist zur Aufnahme der Schraube 52 etwas größer als der Durchmesser des gewindefreien Bereiches 60 der Schraube 52 , während ihr mit Gewinde versehene Ende 58 in die Gewindebohrung 9 einschraubbar ist.The diameter of the through hole 13 in the tab 8 for receiving the screw 52 is slightly larger than the diameter of the unthreaded area 60 of the Screw 52, while its threaded end 58 can be screwed into the threaded bore 9.

Beim Einschrauben der Schraube 52 in die Gewindebohrung 9 werden die Laschen 6, 8 miteinander verspannt, wobei das in Fig. 6 mit den Bezugszeichen 62, 64 bezeichnete elastische Material der Dichtflächen zusammengedrückt wird. Beim Erreichen eines durch den axialen Abstand der axialen Stirnfläche der Schulter 61 von dem freien Ende der Schraube 52 bestimmten maximalen Einschraubweges gelangt die Stirnfläche der Schulter 61 an der der Lasche 6 zugewandten Seite des Verstärkungselementes 7 der Lasche 8 nach Art eines Anschlages definiert zur Anlage, so daß ein weiteres Einschrauben der Schraube 52 und damit ein weiteres Zusammendrücken des elastischen Materiales 62, 64 der Dichtflächen verhindert ist.When the screw 52 is screwed into the threaded bore 9, the tabs 6, 8 are clamped to one another, the elastic material of the sealing surfaces designated by reference numerals 62, 64 in FIG. 6 being compressed. When a maximum screwing-in distance determined by the axial distance of the axial end face of the shoulder 61 from the free end of the screw 52 is reached, the end face of the shoulder 61 comes to rest on the side of the reinforcing element 7 of the tab 8 facing the tab 6 in the manner of a stop, so that a further screwing in of the screw 52 and thus a further compression of the elastic material 62, 64 of the sealing surfaces is prevented.

Durch den Anschlag ist der Einschraubweg der Schraube begrenzt, so daß auch das Maß der Zusammendrückung des elastischen Materiales begrenzt ist. Eine übermäßige Zusammendrückung ist somit zuverlässig verhindert.The screw-in path of the screw is limited by the stop, so that the degree of compression of the elastic material is also limited. Excessive compression is thus reliably prevented.

Das Maß der Zusammendrückung ist durch den axialen Abstand der axialen Stirnfläche der Schulter 61 von dem freien Ende 66 der Schraube 52 wählbar.The degree of compression can be selected by the axial distance of the axial end face of the shoulder 61 from the free end 66 of the screw 52.

In Fig. 7 ist ein weiteres Ausführungsbeispiel eines Anschlages zur Begrenzung des Einschraubweges dargestellt. Bei diesem Ausführungsbeipiel ist der Anschlag durch Nasen 68, 70 gebildet, die aus dem Verstärkungselement 5 ausgestanzt und so an die Lasche 8 angeformt sind. Die Nasen 68, 70 stehen in Richtung auf den Kopf einer nicht dargestellten Schraube axial über das Verstärkungselement vor.7 shows a further exemplary embodiment of a stop for limiting the screwing-in path. In this exemplary embodiment, the stop is formed by lugs 68, 70, which are punched out of the reinforcing element 5 and thus molded onto the tab 8. The lugs 68, 70 protrude axially over the reinforcing element in the direction of the head of a screw, not shown.

Abweichend von Fig. erfolgt die Verbindung der Laschen 6, 8 mit nur einer Schraube, so daß die Lasche lediglich eine Durchgangsbohrung 13 aufweist. Beim Einschrauben in die Gewindebohrung 13 gelangt die nicht dargestellte Schraube beim Erreichen eines durch die axiale Länge der Nasen 68, 70 vorbestimmten Einschraubweges mit der in Einschraubrichtung vorderen Stirnfläche an den Nasen 68, 70 zur Anlage, so daß auf diese Weise der Einschraubweg und damit das Maß der Zusammendrückung des elastischen Materiales der Dichtflächen begrenzt ist.Deviating from Fig. The connection of the tabs 6, 8 takes place with only one screw, so that the tab only has a through hole 13. When screwing into the threaded bore 13, the screw, not shown, comes into contact with the nose 68, 70 when reaching a screw-in path predetermined by the axial length of the lugs 68, 70, so that the screw-in path and thus that Degree of compression of the elastic material of the sealing surfaces is limited.

In Fig. 8 ist eine Abwandlung des Ausführungsbeispieles gemäß Fig. 7 dargestellt, bei dem der Anschlag durch eine zu der nicht dargestellten Schraube koaxiale Scheibe 72 gebildet ist. Die Scheibe 72 kann fest mit dem Verstärkungselement 7 verbunden oder lose auf dieses aufgelegt sein.FIG. 8 shows a modification of the exemplary embodiment according to FIG. 7, in which the stop is formed by a washer 72 which is coaxial with the screw (not shown). The disk 72 can be firmly connected to the reinforcing element 7 or can be placed loosely on the latter.
