Description

Die Erfindung betrifft einen elektrischen Steckverbinder mit einem im Wesentlichen rohrförmigen abgewinkelten Steckverbindergehäuse, das einen Anschlussschenkel und einen Verbindungsschenkel aufweist, wobei in den Anschlussschenkel ein Anschlusskabel einführbar und in den Verbindungsschenkel ein Isolierkörper einsetzbar oder eingesetzt ist.The invention relates to an electrical connector having a substantially tubular angled connector housing having a connecting leg and a connecting leg, wherein in the connecting leg a connecting cable inserted and inserted into the connecting leg an insulating body or is used.

Gattungsgemäße Winkelsteckverbinder sind aus dem Stand der Technik in vielfältigen Ausführungsformen bekannt. Bei bekannten Winkelsteckverbindern besteht häufig das Problem, dass das in den Anschlussschenkel eingeführte Anschlusskabel schwierig mit den Steckkontakten des in dem Verbindungsschenkel angeordneten Isolierkörpers verbindbar ist. Häufig ist dies nur bei von dem Verbindungsschenkel gelöstem Isolierkörper möglich. Zur Behebung dieses Problems ist es bekannt, das Steckverbindergehäuse mit einem lösbaren, von dem Steckverbindergehäuse abnehmbaren Deckel zu versehen, der anschlussseitig über eine Öffnung Zugang zu dem Isolierkörper und den darin aufgenommenen elektrischen Kontakten schafft. Dabei sind der Anschlussschenkel und der Verbindungsschenkel des Steckverbindergehäuses einstückig ausgebildet und der Deckel üblicherweise an einem Übergang des Anschlussschenkels zu dem Verbindungsschenkel, in der Regel anschraubbar, angeordnet. Ein solches mit einem Deckel verschließbares Steckverbindergehäuse ist beispielsweise in der DE 10 2005 026 401 B4 offenbart.Generic angle connectors are known from the prior art in various embodiments. In known angle plug connectors, there is often the problem that the connecting cable inserted into the connecting leg is difficult to connect to the plug contacts of the insulating body arranged in the connecting leg. Often this is only possible with dissolved from the connecting leg insulator. To remedy this problem, it is known to provide the connector housing with a detachable, removable from the connector housing cover, which provides connection side via an opening access to the insulating body and the electrical contacts received therein. In this case, the connecting leg and the connecting leg of the connector housing are integrally formed and the lid usually at a transition of the connecting leg to the connecting leg, usually screwed arranged. One Such closable with a lid connector housing is for example in the DE 10 2005 026 401 B4 disclosed.

Nachteilig erscheint bei dem aus der DE 10 2005 026 401 B4 bekannten, mit einem Deckel verschließbaren Steckverbindergehäuse, dass für das Anschrauben des Deckels ein Werkzeug benötigt wird, wobei gleichzeitig die teilweise starren einzelnen Leiter des Kabels mit Kraft in das Gehäuse gedrückt werden müssen. Dazu erschwert die enge Öffnung das Einführen des Kabels in den Anschlussschenkel unnötig und beengt zudem den Zugang zu dem im Verbindungsschenkel angeordneten Isolierkörper. Insbesondere ist dies hinderlich für das Verbinden der Litzenleitungen des Kabels mit bereits im Isolierkörper aufgenommenen elektrischen Steckkontakten oder das Einführen von an den Litzenleitungen angeschlagenen Steckkontakten in den Isolierkörper, wenn der Isolierkörper im Verbindungsschenkel angeordnet ist.The disadvantage appears in the from the DE 10 2005 026 401 B4 known, with a lid closable connector housing that a tool is required for screwing the lid, at the same time the partially rigid individual conductors of the cable must be pressed with force into the housing. For this purpose, the narrow opening unnecessarily complicates the insertion of the cable into the connecting leg and also restricts access to the insulating body arranged in the connecting leg. In particular, this is a hindrance to the connection of the stranded wires of the cable with already recorded in the insulating body electrical plug contacts or the insertion of posted on the stranded wire plug contacts in the insulating body, when the insulating body is arranged in the connecting leg.

US-A-5176536 offenbart einen elektrischen Steckverbinder nach dem Oberbegriff des Anspruchs 1. US-A-5176536 discloses an electrical connector according to the preamble of claim 1.

EP-A-1383209 offenbart einen elektrischen Steckverbinder mit einem im wesentlichen rohrförmigen abgewinkelten Steckverbindergehäuse, das einen Anschlussschenkel und einen Verbindungsschenkel aufweist, wobei der Anschlussschenkel zwei zumindest teilweise rinnenförmige Schalenteile aufweist. EP-A-1383209 discloses an electrical connector having a substantially tubular angled connector housing having a terminal leg and a connecting leg, wherein the terminal leg has two at least partially channel-shaped shell parts.

Ausgehend von dem vorstehend beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Möglichkeit vorzuschlagen, die zum einen das Durchführen des Kabels durch den Anschlussschenkel erleichtert und zum anderen einen besseren Zugang zu dem im Verbindungsschenkel festgelegten Isolierkörper ermöglicht.Based on the above-described prior art, the present invention seeks to propose a way that facilitates the passage of the cable through the connecting leg and on the other hand allows better access to the insulator fixed in the connecting leg.

Diese Aufgabe wird erfindungsgemäß durch einen ein im wesentlichen rohrförmiges abgewinkeltes Steckverbindergehäuse aufweisenden elektrischen Steckverbinder mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind den rückbezogenen Patentansprüchen zu entnehmen. Danach weist der Anschlussschenkel des erfindungsgemäßen elektrischen Steckverbinders zwei zumindest teilweise rinnenförmige Schalenteile auf, die lösbar miteinander verbunden und in axialer Richtung voneinander trennbar sind, wobei eines der Schalenteile an dem Verbindungsschenkel angeformt ist. Das nicht angeformte Schalenteil wird in der weiteren Beschreibung als freies Schalenteil bezeichnet. Das angeformte und das freie Schalenteil bilden zusammengefügt einen rohrförmigen Verbindungsabschnitt des Anschlussschenkels, der sich rechtwinklig oder stumpfwinklig gegenüber dem Verbindungsschenkel erstreckt.This object is achieved by a substantially tubular angled connector housing having electrical connector having the features of claim 1. Further advantageous embodiments can be found in the dependent claims. Thereafter, the connecting leg of the electrical connector according to the invention comprises two at least partially channel-shaped shell parts which are releasably connected to each other and separable from each other in the axial direction, wherein one of the shell parts is integrally formed on the connecting leg. The non-molded shell part is referred to in the further description as a free shell part. The molded and the free shell part form joined together a tubular connecting portion of the connecting leg, which extends at right angles or obtusely opposite the connecting leg.

Der Verbindungsabschnitt weist vorzugsweise eine Haupttrennebene auf, die parallel zu der Mittelachse des Verbindungsabschnittes und orthogonal zu der Mittelachse des Verbindungsschenkels verläuft, wobei die Haupttrennebene den Verbindungsschenkel vollständig senkrecht zu dessen Mittelachse teilt. Diese Trennebene kann sich axial entlang dem Anschlussschenkel über die Gesamtlänge oder über eine Teillänge erstrecken. Sofern sich die Haupttrennebene nur über eine Teillänge des Anschlussschenkels ausdehnt, weist der Verbindungsabschnitt zusätzlich mindestens eine Nebentrennebene auf, die in einem rechten oder stumpfen Winkel gegenüber der Haupttrennebene angeordnet ist und sich ausgehend von der Haupttrennebene bis hin zu der Außenseite des Verbindungsabschnittes zwischen den Schalenteilen erstreckt. Abhängig von der Lage der Haupttrennebene wird der Verbindungsabschnitt in radialer Richtung symmetrisch oder asymmetrisch geteilt.The connecting portion preferably has a main parting plane parallel to the central axis of the connecting portion and orthogonal to the central axis of the connecting leg, the main parting plane dividing the connecting leg completely perpendicular to the central axis thereof. This parting plane can extend axially along the connecting leg over the entire length or over a partial length. If the main parting plane expands over only a partial length of the connecting leg, the connecting section additionally has at least one outward separating plane, which is arranged at a right or obtuse angle with respect to the main parting plane and extends from the main parting plane to the outside of the connecting part between the shell parts , Depending on the position of the main separating plane, the connecting section is divided symmetrically or asymmetrically in the radial direction.

Das an den Verbindungsschenkel angeformte Schalenteil erstreckt sich vorzugsweise über den Querschnitt des Verbindungsschenkels hinweg bis zu dessen Gehäusewandung. Im Bereich des Isolierkörpers ist eine in Draufsicht rund erscheinende ovale Öffnung ausgebildet, so dass ein Zugang zu der Anschlussseite des Isolierkörpers geschaffen ist. Im Hinblick auf die Hauptrennebene ist das angeformte Schalenteil derart an dem Verbindungsschenkel angeordnet, dass die offene Seite des rinnenförmigen Schalenteils dem Isolierkörper ferner liegt als dessen geschlossene Seite. Das angeformte Schalenteil weitet sich mit zunehmenden axialen Abstand von dem Isolierkörper nach außen auf. Bei von dem an den Verbindungsschenkel angeformten Schalenteil getrennten freien Schalenteil des Anschlussschenkels ist damit der Isolierkörper anschlussseitig frei zugänglich, wobei die Litzenleitungen des Kabels einfach zu diesem hin geführt und in dem angeformten rinnenförmigen Schalenteil verlegt werden können. Das Einführen und Durchführen des Kabels durch den Anschlussschenkel ist ebenso vereinfacht, da sich das freie rinnenförmige Schalenteil entsprechend über einen großen Teil der Länge des Anschlussschenkels erstreckt und so genügend Raum für ein einfaches hindernisfreies Arbeiten zur Verfügung steht. Die beiden Schalenteile lassen sich bedingt durch die Orientierung der Haupttrennebene gegenüber dem Steckverbindergehäuse, gegebenenfalls in Verbindung mit der Nebentrennebene, im Wesentlichen radial voneinander trennen. Abhängig vom Verlauf der Nebentrennebene kann dabei zusätzlich auch eine geringe axiale Bewegung der Schalenteile relativ zueinander erforderlich sein.The molded onto the connecting leg shell part preferably extends beyond the cross section of the connecting leg away up to the housing wall. In the region of the insulating body, an oval opening that appears to be round in plan view is formed, so that access to the connection side of the insulating body is created. With regard to the main parting plane, the molded shell part is arranged on the connecting leg in such a way that the open side of the channel-shaped shell part lies further on the insulating body than its closed side. The molded shell part expands with increasing axial distance from the insulator to the outside. When separated from the molded on the connecting leg shell part free shell part of the connecting leg so that the insulating body connection side is freely accessible, the stranded conductors of the cable can be easily out to this and laid in the molded channel-shaped shell part. The insertion and passage of the cable through the connecting leg is also simplified because the free channel-shaped shell part accordingly extends over a large part of the length of the connecting leg and so is enough space for a simple obstacle-free work available. The two shell parts can be due to the orientation of the main parting plane with respect to the connector housing, possibly in conjunction with the secondary parting plane, substantially radially separate from each other. Depending on the course of the secondary dividing plane, a slight axial movement of the shell parts relative to each other may additionally be required.

Vorzugsweise sind die beiden Schalenteile halbschalenförmig ausgebildet, wobei das nicht an den Verbindungsschenkel angeformte freie Schalenteil an seinem dem Verbindungsschenkel abgewandten freien Ende in einen rohrförmigen Einführabschnitt übergeht. Der Einführabschnitt schließt damit direkt unmittelbar an den Verbindungsabschnitt an. An einem solchen Einführabschnitt kann problemlos eine Zugentlastung und ein Schirmanschluss für das Anschlusskabel angeordnet und fixiert werden. Die Schalenteile als Halbschalen auszubilden ist von besonderem Vorteil, da der Freiraum im Bereich des Verbindungsschenkels wie auch des Anschlussschenkels damit maximal und somit optimal ist.Preferably, the two shell parts are formed half-shell-shaped, wherein the not formed on the connecting leg free shell part at its side facing away from the connecting leg free end merges into a tubular insertion section. The insertion section thus directly adjoins the connection section directly. At such an introduction section, a strain relief and a shield connection for the connection cable can be easily arranged and fixed. Forming the shell parts as half-shells is of particular advantage, since the free space in the region of the connecting leg as well as the connecting leg is thus maximum and thus optimal.

Bei einer bevorzugten Ausführungsform der Erfindung sind die beiden Schalenteile aneinander lösbar festlegbar oder festgelegt. Damit kann je nach Ausführung eine Vorfixierung oder eine endgültige Verbindung der beiden Schalenteile erreicht werden. Ein unerwünschtes Lösen der beiden Schalenteile voneinander ist damit auch sicher verhindert. Eine solche Festlegung kann beispielsweise über eine Schraubverbindung erfolgen. Diese kann von korrespondierend ausgebildeten Einhängemittel oder Rastmittel unterstützt sein. Die Schraubverbindung kann axial, radial und/oder schräg zu der Mittelachse des Verbindungsabschnittes erfolgen. Dazu können Schrauben, Muttern oder Hülsen geeigneter Größe mit entsprechend angeformten Gewinden verwendet werden. Prinzipiell kann anstelle der Schraubverbindung auch eine geeignet ausgebildete Rastverbindung vorgesehen sein, die miteinander korrespondierende Einhängemittel oder Rastmittel aufweist.In a preferred embodiment of the invention, the two shell parts are releasably secured to each other or fixed. Thus, depending on the design, a prefixing or a final connection of the two shell parts can be achieved. An undesirable loosening of the two shell parts from each other is thus also reliably prevented. Such a determination can be made for example via a screw connection. This can be supported by correspondingly formed hooking or locking means. The screw connection can be made axially, radially and / or obliquely to the central axis of the connecting portion. For this purpose, screws, nuts or sleeves of suitable size can be used with correspondingly formed threads. In principle, instead of the screw connection, it is also possible to provide a suitably designed latching connection which has coupling means or latching means which correspond to one another.

Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen elektrischen Steckverbinders weisen die Schalenteile an ihren sich axial erstreckenden Rändern axial verlaufende Führungselemente auf. Über diese Führungselemente können die beiden Schalenteile besonders einfach einander gegenüber genau ausgerichtet zusammengeführt und aneinander gehalten werden. Die sich axial erstreckenden Ränder definieren die Haupttrennebene des Verbindungsabschnittes des Steckverbindergehäuses. Die Führungselemente können sich dabei ganz oder nur teilweise entlang den axialen Rändern erstrecken. Sie sind dabei derart angeordnet und ausgebildet, dass ein radiales Verschieben der beiden Schalenteile einander gegenüber ausgeschlossen ist. Die Führungselemente können die beiden Schalenteile zusätzlich noch lösbar miteinander verriegeln, so dass bis zu der sicheren Verschraubung des Verbindungsabschnittes ein unbeabsichtigtes Trennen sichergestellt ist. Es hat sich als besonders zweckmäßig erwiesen, mehrere nur partiell an den Rändern angeordnete Führungselemente an den beiden Schalen anzuformen. Damit können die beiden Schalenteile besonders einfach aufeinandergesetzt, einander gegenüber verschoben und auch verriegelt werden.In a particularly preferred embodiment of the electrical connector according to the invention, the shell parts have axially extending guide elements on their axially extending edges. About these guide elements, the two shell parts can be particularly easily matched to each other exactly aligned and held together. The axially extending edges define the main parting plane of the connecting portion of the connector housing. The guide elements may extend completely or only partially along the axial edges. They are arranged and designed such that a radial displacement of the two shell parts is excluded from each other. The guide elements can additionally releasably lock the two shell parts together, so that unintentional separation is ensured up to the secure screw connection of the connecting portion. It has proved to be particularly useful to form a plurality of only partially arranged at the edges guide elements on the two shells. Thus, the two shell parts can be particularly easily stacked, moved against each other and also locked.

Vorzugsweise sind die Führungselemente gegenüber den Rändern geneigt angeordnet und pressen die Schalenteile beim axialen Zusammenführen, d. h. beim axialen Verschieben des freien Schalenteils in Richtung des angeformten Schalenteils in Umfangsrichtung aneinander. Die Presskraft nimmt umso mehr zu, je weiter das freie Schalenteil auf dem angeformten Schalenteil in Richtung des Verbindungsschenkels geschoben wird. Dies ist besonders dann von Nutzen, wenn zwischen den Schalenteilen ein umlaufender Dichtring in einer bevorzugten Ausführungsform der Erfindung angeordnet ist, der den Verbindungsabschnitt des Steckverbindergehäuses abdichtet. Der Dichtring ist vorzugsweise in einer Ringnut des angeformten und/oder des freien Schalenteils aufgenommen.Preferably, the guide elements are arranged inclined relative to the edges and press the shell parts during axial merging, d. H. during axial displacement of the free shell part in the direction of the molded shell part in the circumferential direction to each other. The pressing force increases all the more, the farther the free shell part is pushed on the molded shell part in the direction of the connecting leg. This is particularly useful when between the shell parts a circumferential sealing ring is arranged in a preferred embodiment of the invention, which seals the connecting portion of the connector housing. The sealing ring is preferably received in an annular groove of the molded and / or the free shell part.

Bei einer begünstigten Ausführungsform der Erfindung ist die Schraubverbindung der beiden Schalenteile über eine von dem rohrförmigen Einführabschnitt getragene Schraubhülse herstellbar, wobei die Schraubhülse ein Innengewinde und der Verbindungsabschnitt mindestens ein an einem oder beiden Schalenteilen angeordnetes Außengewindesegment aufweist. Die Schraubhülse übergreift die beiden Schalenteile außen formschlüssig und presst gleichzeitig eine optional vorgesehene Zugentlastung und gegebenenfalls ein Schirmanschluss für das für das Anschlusskabel an den rohrförmigen Einführabschnitt des Anschlussschenkels an. Dabei richtet die Schraubhülse die beiden Schalenteile sowohl axial wie auch radial exakt zueinander aus. Damit kann die Schraubverbindung auf einfache Weise sicher hergestellt und falls notwendig gelöst werden. Durch die Schraubhülse wird die notwendige Kraft zum entgültigen Zusammenfügen der Schalenteile aufgebracht. Weiterer Vorteil ist, dass keine zwei Schraubhülsen notwendig sind, von denen eine die beiden Schalenteile unverrückbar aneinander festlegt und die andere die Zugentlastung bzw. den Schirmanschluss Kraft beaufschlagt.In a favorable embodiment of the invention, the screw connection of the two shell parts can be produced via a screw sleeve carried by the tubular insertion section, wherein the screw sleeve has an internal thread and the connecting section has at least one external thread segment arranged on one or both shell parts. The screw sleeve engages over the two shell parts form-fit outside and at the same time presses an optionally provided strain relief and optionally a shield connection for that for the connection cable to the tubular insertion section of the connecting leg. The screw sleeve aligns the two shell parts both axially and radially exactly to each other. Thus, the screw can be easily prepared in a simple manner and if necessary solved. Through the screw the necessary force for final assembly of the shell parts is applied. Another advantage is that no two screw sleeves are necessary, one of which sets the two shell parts immovable together and the other applied to the strain relief and the shield connection force.

Vorzugsweise weist der Verbindungsabschnitt nur ein Außengewindesegment auf, das an dem an den Verbindungsschenkel angeformten Schalenteil ausgebildet ist. Damit entfällt das exakte axiale Ausrichten der beiden Schalenteile zueinander vor der Verschraubung, die bei jeweils einem auf dem angeformten und dem freien Schalenteil angeordneten Gewindesegment notwendig wäre, um das Innengewinde mit den beiden Gewindesegmenten in Eingriff bringen. Im festgezogenen Zustand stützt sich die Schraubhülse an einem hinteren, dem Verbindungsschenkel abgewandten Ende des Anschlussschenkels axial ab. Aufgrund des gepressten Dichtringes ist ein axiales Ausrichten der beiden Schaltenteile einander gegenüber nicht oder nur mit großem Kraftaufwand möglich.Preferably, the connecting portion has only one external thread segment, which is formed on the formed on the connecting leg shell part. This eliminates the exact axial alignment of the two shell parts to each other before screwing, which would be necessary in each case one arranged on the molded and the free shell part thread segment to bring the internal thread with the two thread segments into engagement. In the tightened state, the threaded sleeve is axially supported at a rear end of the connecting leg facing away from the connecting leg. Due to the pressed sealing ring axial alignment of the two switching parts is not possible with each other or only with great effort.

Durch die Teilung des Anschlussschenkels wird der Winkelsteckverbinder in diesem Bereich flach gehalten. Für die Montage ist kein gesondertes Werkzeug erforderlich, so dass das Konfektionieren des Winkelsteckverbinders vereinfacht ist.By dividing the connecting leg of the angle connector is kept flat in this area. For the assembly no separate tool is required, so that the assembly of the angle connector is simplified.

Die Figur 2 zeigt eine Ausschnittsvergrößerung des Steckverbinders 1 aus Figur 1, die sich auf den Anschlussschenkel 3 und das mit dem Anschlussschenkel 3 verbundene Ende des Verbindungsschenkels 4 beschränkt. In dem Verbindungsschenkel 4 ist der Isolierkörper 5 unverrückbar und unlösbar festgelegt. Der Anschlussschenkel 3 weist zwei zumindest teilweise rinnenförmige Schalenteile 12, 13 auf, die lösbar miteinander verbunden und im Wesentlichen in axialer Richtung voneinander trennbar sind. Dabei ist eines der Schalenteile 12, 13 an dem Verbindungsschenkel 4 als angeformtes Schalenteil 12 ausgebildet und bildet mit dem anderen freien Schalenteil 13 im zusammengefügten Zustand einen rohrförmigen Verbindungsabschnitt 14 des Anschlussschenkels 3. Die beiden Schalenteile 12, 13 sind vorzugsweise halbschalenförmig ausgebildet, wobei das nicht an dem Verbindungsschenkel 4 angeformte freie Schalenteil 13 an seinem dem Verbindungsschenkel 4 abgewandten freien Ende 8 in einen rohrförmigen Einführabschnitt 15 für das in der Figur nicht gezeigte Anschlusskabel übergeht. Der Einführabschnitt 15, an dem die Zugentlastung 9 mit dem Schirmanschluss 10 angeordnet ist, schließt direkt an den Verbindungsabschnitt 14 an. Die Schraubhülse 11 übergreift die beiden Schalenteile 12, 13 teilweise in axialer Richtung und bildet eine Schraubverbindung 16 für den Verbindungsabschnitt 14 verbunden, die die beiden Schalenteile 12, 13 sicher miteinander verbindet.The FIG. 2 shows an enlarged detail of the connector 1 from FIG. 1 , which is limited to the connecting leg 3 and connected to the connecting leg 3 end of the connecting leg 4. In the connecting leg 4, the insulating body 5 fixed immovable and insoluble. The connecting leg 3 has two at least partially channel-shaped shell parts 12, 13, which are releasably connected to each other and substantially separated from each other in the axial direction. In this case, one of the shell parts 12, 13 is formed on the connecting leg 4 as a molded shell part 12 and forms with the other free shell part 13 in the assembled state, a tubular connecting portion 14 of the connecting leg 3. The two shell parts 12, 13 are preferably formed shell-shaped, which is not formed on the connecting leg 4 free shell part 13 at its side facing away from the connecting leg 4 free end 8 merges into a tubular insertion section 15 for the connecting cable, not shown in the figure. The insertion section 15, on which the strain relief 9 is arranged with the shield connection 10, directly adjoins the connection section 14. The screw sleeve 11 engages over the two shell parts 12, 13 partially in the axial direction and forms a screw 16 for the connecting portion 14, which connects the two shell parts 12, 13 together.

Der Verbindungsabschnitt 14 weist eine Haupttrennebene 17 auf, die sich parallel zu der Mittelachse 18 des Verbindungsabschnittes 14 erstreckt. Die Haupttrennebene 17 verläuft durch die Mittelachse 18 und dehnt sich axial bis hin zu dem Einführabschnitt 15 des Anschlussschenkels 3 aus. Der Verbindungsabschnitt 14 weist zudem eine Nebentrennebene 19 auf, die sich geneigt gegenüber der Haupttrennebene 17, ausgehend von der Haupttrennebene 17 bis zu der Außenseite 20 der Schalenteile 12, 13 erstreckt.The connecting portion 14 has a main parting plane 17 which extends parallel to the central axis 18 of the connecting portion 14. The main parting plane 17 extends through the central axis 18 and extends axially as far as the insertion section 15 of the connecting leg 3. The connecting portion 14 also has a secondary dividing plane 19, which extends inclined with respect to the main parting plane 17, starting from the main parting plane 17 to the outside 20 of the shell parts 12, 13.

Die beiden Schalenteile 12, 13 sind lösbar aneinander festgelegt. Das freie Schalenteil 13 und das angeformte Schalenteil 12 sind zum einen über die Schraubverbindung 16 durch die Schraubhülse 11 aneinander festgelegt und zum anderen durch mehrere Spanneinrichtungen 21, die an den sich axial erstreckenden Rändern 22, 22' der Schalenteile 12 bzw. 13 als axial verlaufende Führungselemente 23, 23' ausgebildet sind. Die Führungselemente 23 des angeformten Schalenteils 12 sowie die Führungselemente 23' des freien Schalenteils 13 sind an den Rändern 22 bzw. 22' geneigt angeordnet und pressen die Schalenteile 12, 13 beim axialen Zusammenführen in Umfangsrichtung aneinander.The two shell parts 12, 13 are releasably secured together. The free shell part 13 and the molded shell part 12 are fixed on the one hand via the screw 16 through the threaded sleeve 11 to each other and on the other by a plurality of clamping devices 21, at the axially extending edges 22, 22 'of the shell parts 12 and 13 as axially extending Guide elements 23, 23 'are formed.
