Description

Die Erfindung betrifft ein Steckergehäuse, das besonders zur Aufnahme eines vorkonfektionierten Kabels geeignet ist.The invention relates to a connector housing, particularly for receiving a Pre-assembled cable is suitable.

Ein vorkonfektioniertes Kabel zeichnet sich dadurch aus, daß seine Adern bereits mit Kontakten verbunden sind, die wiederum bereits in einem Isolierkörper angeordnet sein können. Die vorkonfektionierten Kabel werden beispielsweise dazu verwendet, vor Ort die Verkabelung von elektrischen Geräten vorzunehmen, wobei die Kabel je nach den räumlichen Verhältnissen in unterschiedlichen Richtungen zu den Geräten geführt werden müssen. Beim Anschließen des Kabels wird der Isolierkörper mit den Kontakten in ein Steckergehäuse eingelegt, das den räumlichen Verhältnissen vor Ort angepaßt ist, beispielsweise hinsichtlich der Kabelabgangsrichtung. Das Problem bei vorkonfektionierten Leitungen besteht darin, daß aufgrund der bereits angebrachten Kontakte und des Isolierkörpers das Kabel nicht in axialer Richtung durch eine Kabelverschraubung bzw. Kabelabdichtung in ein beispielsweise geschlossenes Gehäuse eingeführt werden kann. Es ist statt dessen erforderlich, ein mindestens zweiteiliges Gehäuse zu verwenden, dessen Trennfuge so angeordnet ist, daß im geöffneten Zustand das Kabel zwischen die beiden Gehäuseteile gelegt werden kann. Ähnliche Probleme ergibt sich hinsichtlich der Abdichtung des Kabels im Bereich des Kabeldurchgangs durch das Gehäuse. Es kann kein geschlossener Dichtring verwendet werden, da dieser nicht über den Isolierkörper geschoben werden kann. Statt dessen muß ein entweder geschlitzter oder mehrteiliger Dichtring verwendet werden.A prefabricated cable is characterized in that its wires already connected with contacts, which in turn already in an insulating body can be arranged. The pre-assembled cables, for example used to make the cabling of electrical equipment on site, The cables are different depending on the spatial conditions Directions must be guided to the devices. When connecting the cable the insulating body is inserted with the contacts in a connector housing, the adapted to local conditions, for example in terms of Cable outlet direction. The problem with prefabricated cables exists in that due to the already attached contacts and the insulator the Cable not in the axial direction by a cable gland or Cable seal are inserted into an example closed housing can. It is instead necessary to have at least a two-part housing use, the parting line is arranged so that in the open state Cable can be placed between the two housing parts. Similar problems arises with regard to the sealing of the cable in the area of the cable passage through the housing. It can not use a closed seal be, because this can not be pushed over the insulating body. Instead of this must be either a slotted or multi-part seal used become.

Der Nachteil bei mehrteiligen Gehäusen und mehrteiligen bzw. geschlitzten Dichtringen besteht darin, daß eine zuverlässige Abdichtung gegen Schmutzeintritt nur mit besonderem Aufwand möglich ist, insbesondere wenn höhere IP-Schutzklassen erreicht werden sollen.The disadvantage of multi-part housings and multi-part or slotted Sealing rings is that a reliable seal against dirt only with special effort is possible, especially if higher IP protection classes to be achieved.

Die Aufgabe der Erfindung besteht dementsprechend darin, ein Steckergehäuse zu schaffen, das mit einem vorkonfektionierten Kabel bestückt werden kann und mit geringem Aufwand hohe Anforderungen an die Dichtigkeit einhalten kann.The object of the invention is accordingly a plug housing to create, which are equipped with a pre-assembled cable can and with little effort high demands on the tightness can comply.

Zu diesem Zweck ist erfindungsgemäß ein Steckergehäuse vorgesehen mit einem ersten Gehäuseteil und einem zweiten Gehäuseteil, die entlang einer Trennfuge aneinander anliegen, einem Kabeldurchgang für ein Kabel aus dem Inneren des Steckergehäuses nach außen, wobei die Trennfuge im Bereich des Kabeldurchgangs verläuft, und einem Dichteinsatz, der im Kabeldurchgang angeordnet ist, wobei der Dichteinsatz mit einem Schlitz versehen ist, so daß er auf ein vorkonfektioniertes Kabel aufgesteckt werden kann, und wobei der Dichteinsatz so angeordnet ist, daß sein Schlitz gegenüber der Trennfuge versetzt ist. Diese Gestaltung gewährleistet, daß der Dichteinsatz mit einem darin angeordneten Kabel in eines der beiden Gehäuseteile eingesetzt werden kann, wo er durch Reibung fixiert bleibt. Anschließend kann das zweite Gehäuseteil aufgesetzt und festgeschraubt werden, wodurch der Dichteinsatz so komprimiert wird, daß er gut abdichtet.For this purpose, a connector housing according to the invention is provided with a first housing part and a second housing part, which along a Abut one another, a cable passage for a cable from the Inside the plug housing to the outside, the parting line in the area of Cable passage runs, and a sealing insert, in the cable passage is arranged, wherein the sealing insert is provided with a slot so that he can be plugged onto a pre-assembled cable, and wherein the Seal insert is arranged so that its slot offset from the parting line is. This design ensures that the sealing insert with a therein arranged cable can be used in one of the two housing parts, where he remains fixed by friction. Subsequently, the second housing part mounted and screwed, whereby the sealing insert so compressed that he seals well.

In Figur 1 ist ein Steckverbinder gezeigt, der aus einem Steckergehäuse 5 besteht, in welchem mehrere Steckkontakte aufgenommen sind, die hier von einem sie umgebenden Isolierkörper 7 verdeckt sind. In das Steckergehäuse 5 hinein führt ein Kabel 8, dessen Adern mit den Steckkontakten im Isolierkörper 7 verbunden sind. Das Kabel 8 wird durch einen Kabeldurchgang 9 geführt, in dessen Bereich eine später erläuterte Abdichtung erfolgt.FIG. 1 shows a plug connector which consists of a plug housing 5 consists, in which several plug contacts are included, the here of a surrounding insulating body 7 are covered. In the connector housing 5 into it leads a cable 8, whose wires with the plug contacts in the insulating body. 7 are connected. The cable 8 is passed through a cable passage 9, in the area of which is explained later a seal.

Beim Kabel 8 handelt es sich um ein vorkonfektioniertes Kabel, dessen Adern bereits fest mit den Steckkontakten im Isolierkörper 7 verbunden sind. Hieraus folgt, daß das Steckergehäuse 5 geöffnet werden muß, da es ansonsten nicht möglich wäre, das Kabel zusammen mit dem Isolierkörper 7 in das Steckergehäuse einzulegen. Wie in Figur 2 zu sehen ist, besteht das Steckergehäuse zu diesem Zweck aus einem ersten Gehäuseteil 10 und einem Gehäuseteil 12, die entlang einer umlaufenden Trennfuge 14 (siehe auch Figur 7) aneinander anliegen können. Wie insbesondere in Figur 7 zu sehen ist, ist die Trennfuge 14 gegenüber einer Mittelebene M des Gehäuses geringfügig zu einer Seite versetzt. Dieser Versatz V beträgt weniger als 10 % der gesamten maximalen Breite des Steckergehäuses.The cable 8 is a prefabricated cable whose wires already firmly connected to the plug contacts in the insulating body 7. From this follows that the connector housing 5 must be opened, otherwise it is not it would be possible, the cable together with the insulating body 7 in the connector housing appeal. As can be seen in Figure 2, the plug housing is to this purpose from a first housing part 10 and a housing part 12, the along a circumferential parting line 14 (see also Figure 7) abut each other can. As can be seen in particular in Figure 7, the parting line 14 is opposite a median plane M of the housing slightly offset to one side. This Offset V is less than 10% of the total maximum width of the Plug housing.

Der Kabeldurchgang 9 wird von der Trennfuge 14 in zwei Teile unterteilt, von denen sich der größere Teil im ersten Gehäuseteil 10 und der kleinere Teil im zweiten Gehäuseteil 12 befindet. Der sich im ersten Gehäuseteil 10 befindende Teil des Kabeldurchgangs 9 (siehe insbesondere Figur 4) ist U-förmig mit einem Boden 16 und zwei Seitenwänden 18 ausgeführt. Auf jeder der Seitenwände 18 ist ein vorstehender Steg 20 ausgebildet, der auf seiner der Trennfuge 14 zugewandten Seite mit einer zu dieser parallelen Stirnwand 22 versehen ist und auf seiner dem Boden 16 zugewandten Seite im Bereich des Übergangs der Seitenwände 18 zum Boden 16 ausläuft.The cable passage 9 is divided by the parting line 14 into two parts, from which are the larger part in the first housing part 10 and the smaller part in the second housing part 12 is located. The located in the first housing part 10 Part of the cable passage 9 (see in particular Figure 4) is U-shaped with a Floor 16 and two side walls 18 executed. On each of the side walls 18 is a projecting web 20 is formed on its parting line of the 14th facing side is provided with a parallel to this end wall 22 and on its side facing the bottom 16 in the region of the transition of Side walls 18 to the bottom 16 expires.

Das erste Gehäuseteil 10 ist mit einer umlaufenden Dichtung 24 versehen, die entlang der Trennfuge 14 verläuft und auch durch den sich im ersten Gehäuseteil 10 befindenden Teil des Kabeldurchgangs 9 verläuft. Die freiliegende Oberfläche der Dichtung 24 verläuft dabei entsprechend der Kontur des Kabeldurchgangs 9, springt also an den Stegen 20 nach innen vor. Im Bereich des Übergangs jeder Seitenwand zur Trennfuge 14 ist die Dichtung 24 auf jeder Seite des Kabeldurchgangs 9 mit zwei Vorspannansätzen 26 versehen, die über die Trennfuge hinausstehen und auf ihrer vom Kabeldurchgang 9 abgewandten Seite abgeschrägt sind.The first housing part 10 is provided with a circumferential seal 24, the runs along the parting line 14 and also through which in the first housing part 10 located part of the cable passage 9 extends. The exposed surface the seal 24 extends in accordance with the contour of the cable passage 9, So jumps in on the webs 20 inwards. In the area of transition everyone Side wall to the parting line 14 is the gasket 24 on each side of the Cable passage 9 is provided with two bias lugs 26 which over the Parting line stand out and on their side facing away from the cable passage 9 side are bevelled.

An den Kabeldurchgang 9 schließt sich zum Inneren des Steckergehäuses 5 hin eine Kabelschelle 28 an, von der im ersten Gehäuseteil 10 ein Widerlager 30 ausgebildet ist.At the cable passage 9 closes to the interior of the plug housing. 5 towards a cable clamp 28, from the first housing part 10, an abutment 30th is trained.

Der übrige Teil des Kabeldurchgangs 9 ist im zweiten Gehäuseteil 12 ausgebildet. Auch hier ist eine U-förmige Vertiefung vorgesehen, die einen Boden und zwei Seitenwände aufweist. Weiterhin sind in den Seitenwänden, wie im Gehäuseteil 10, Stege 20 vorgesehen. Im Bereich des Übergangs jeder Seitenwand zur Trennfuge ist eine schräg verlaufende, entsprechend vertiefte Druckfläche 32 zur Aufnahme der Vorspannansätze 26 vorgesehen. The remaining part of the cable passage 9 is in the second housing part 12 educated. Again, a U-shaped recess is provided, which has a bottom and has two side walls. Furthermore, in the side walls, as in Housing part 10, webs 20 are provided. In the area of the transition of each side wall to the parting line is an inclined, correspondingly recessed pressure surface 32nd provided for receiving the biasing lugs 26.

Zur Abdichtung im Bereich des Kabeldurchgangs 9 ist ein Dichteinsatz 34 vorgesehen, der aus Gummi besteht. Das Material des Dichteinsatzes 34 hat eine höhere Härte als das Gummimaterial der Dichtung 24. Der Dichteinsatz 34 setzt sich zusammen aus einem Dichtabschnitt 36, einem Klemmabschnitt 38 und einem dazwischenliegenden Flansch 40. Der Dichtabschnitt 36 ist dafür vorgesehen, im Bereich des eigentlichen Kabeldurchgangs 9 zwischen den beiden U-förmigen Vertiefungen in den beiden Gehäuseteilen 10, 12 angeordnet zu werden. Er hat, ebenso wie der Kabeldurchgang 9, einen etwa quadratischen Querschnitt mit abgerundeten Ecken. Der Dichtabschnitt 38 ist dafür vorgesehen, in der Kabelschelle 28 angeordnet zu werden. Er hat einen runden Querschnitt. Der Flansch 40 ist dafür vorgesehen, in einer Flanschaufnahme 42 im ersten und im zweiten Gehäuseteil 10, 12 aufgenommen zu werden. Er hat ebenfalls einen quadratischen Querschnitt mit abgerundeten Ecken.For sealing in the region of the cable passage 9 is a sealing insert 34th provided, which consists of rubber. The material of the sealing insert 34 has a higher hardness than the rubber material of the seal 24. The sealing insert 34 sets together from a sealing portion 36, a clamping portion 38 and an intermediate flange 40. The sealing portion 36 is for provided, in the area of the actual cable passage 9 between the two U-shaped depressions in the two housing parts 10, 12 arranged to become. He has, as well as the cable passage 9, an approximately square Cross-section with rounded corners. The sealing portion 38 is intended to be arranged in the cable clamp 28. He has a round cross section. The flange 40 is intended to be in a Flanschaufnahme 42 in the first and to be received in the second housing part 10, 12. He has one too square section with rounded corners.

Der Dichteinsatz 34 ist mit einem Schlitz 44 versehen, der in der Mitte einer der Seiten des quadratischen Dichtabschnittes 36 angeordnet ist. Der Schlitz 44 ermöglicht, daß der Dichteinsatz 33 auf das vorkonfektionierte Kabel 8 aufgesetzt werden kann. Auf der Seite des Dichtabschnittes 36, auf der sich der Schlitz 44 befindet, sind zwei Nuten 46 vorgesehen, die jeweils im Bereich einer abgerundeten Ecke beginnen und in einem ausreichenden Abstand vor dem Schlitz 44 enden. Im Bereich des Schlitzes 44 verbleibt also die Wandstärke des Dichtabschnittes 36 in gewohnter Stärke. Die Nuten 46 sind auch auf der in Figur 5 nicht sichtbaren, unteren Seite des Dichtabschnittes 36 angeordnet, so daß der Dichteinsatz 34 zu zwei zueinander senkrechten Ebenen symmetrisch ist. Die erste dieser Ebenen verläuft durch den Schlitz 44, und die Schnittlinie der beiden Ebenen fällt mit der Mittelache des Dichteinsatzes 34 und damit auch mit der Mittelachse des Kabels 8 zusammen.The sealing insert 34 is provided with a slot 44 in the middle of a the sides of the square sealing portion 36 is arranged. The slot 44 allows the sealing insert 33 placed on the pre-assembled cable 8 can be. On the side of the sealing portion 36, on which the slot 44 are two grooves 46 are provided, each in the range of Start rounded corner and leave it at a sufficient distance Slot 44 ends. In the region of the slot 44 thus remains the wall thickness of the Dichtabschnittes 36 in the usual strength. The grooves 46 are also on the in FIG 5 invisible, lower side of the sealing portion 36 is arranged, so that the Seal insert 34 is symmetrical to two mutually perpendicular planes. The first of these planes passes through the slot 44, and the intersection of the two Plains coincides with the Mittelache of the sealing insert 34 and thus also with the Central axis of the cable 8 together.

Zur Anbringung des vorkonfektionierten Kabels 8 im Steckergehäuse 5 wird zuerst der Dichteinsatz 34 auf das Kabel 8 aufgesetzt, indem der Schlitz 44 so weit aufgebogen wird, daß der Dichteinsatz 34 auf das Kabel 8 aufgeschoben werden kann. Dann wird der Isolierkörper 7 in einer ihm zugeordneten Isolierkörperaufnahme 48 im ersten Gehäuseteil 10 angeordnet, und das Kabel 9 wird in den sich im ersten Gehäuseteil 10 befindenden Teil des Kabeldurchgangs 9 eingelegt. Dabei wird der Dichteinsatz 34 so zwischen den Seitenwänden 18 positioniert, daß die beiden Stege 20 in einander gegenüberliegende Nuten 46 des Dichtabschnittes 36 des Dichteinsatzes 34 eingreifen. Der Schlitz 44 befindet sich dabei, da die Trennfuge 14 gegenüber der Mittelebene M des Gehäuses und damit auch der Mitte des Kabeldurchgangs 9 versetzt ist, im Bereich einer der Seitenwände 18 (siehe Figur 7). Dies gewährleistet, daß der Dichteinsatz 34 trotz des leichten Drucks, den das in ihn eingelegte Kabel 8 ausübt und welcher den Schlitz 44 aufzuspreizen sucht, korrekt und mit geschlossenem Schlitz 44 im ersten Gehäuseteil 10 vorfixiert ist. Anschließend kann die Kabelschelle 28 komplettiert werden, indem auf das Widerlager 30 eine Metallklammer 50 aufgeschraubt wird, die auf den Klemmabschnitt 38 des Dichteinsatzes 34 drückt. Auf diese Weise kann das Kabel im Gehäuseteil 10 fixiert werden. Falls gewünscht, kann mit der aus dem Widerlager 30 und der Metallklammer 50 bestehenden Kabelschelle 28 auch ein Schirmgeflecht kontaktiert werden, wenn es sich beim Kabel 8 um ein abgeschirmtes Kabel handelt.To attach the prefabricated cable 8 in the connector housing 5 is First, the sealing insert 34 is placed on the cable 8 by the slot 44 so is bent far that the sealing insert 34 is pushed onto the cable 8 can be. Then, the insulating body 7 in an associated Isolierkörperaufnahme 48 disposed in the first housing part 10, and the cable 9 is in the part of the cable passage 9 located in the first housing part 10 inserted. The sealing insert 34 is thus between the side walls 18th positioned so that the two webs 20 in opposing grooves 46 of the Seal section 36 of the sealing insert 34 engage. The slot 44 is located thereby, since the parting line 14 with respect to the median plane M of the housing and thus also the center of the cable passage 9 is offset, in the area of one of Side walls 18 (see Figure 7). This ensures that the sealing insert 34 despite the slight pressure exerted by the cable inserted into it 8 and which the Slot 44 seeks to spread, correctly and with closed slot 44 in first housing part 10 is prefixed. Subsequently, the cable clamp 28 be completed by a metal clip 50 on the abutment 30 is screwed, which presses on the clamping portion 38 of the sealing insert 34. In this way, the cable can be fixed in the housing part 10. If desired, can with the from the abutment 30 and the metal clip 50th existing cable clamp 28 and a braided shield are contacted, if the cable 8 is a shielded cable.

Abschließend wird das zweite Gehäuseteil 12 auf das erste Gehäuseteil 10 aufgesetzt und mit diesem verschraubt. Dabei wird der Dichteinsatz 34, dessen Abmessungen im Ausgangszustand geringfügig größer sind als die Abmessungen des Kabeldurchgangs 9, leicht zusammengedrückt, so daß er mit Vorspannung an den Seitenwänden des Kabeldurchgangs 9 anliegt. Durch den aufgebrachten Druck wird auch der Schlitz 44 des Dichteinsatzes 34 zusammengedrückt, so daß sich dort eine gute Abdichtung ergibt. Die gute Abdichtung wird vervollständigt durch die umlaufende Dichtung 24, die zum einen zwischen den beiden Gehäuseteilen abdichtet und zum anderen, aufgrund der Vorspannansätze 26 in Kombination mit den Druckflächen 32, im Bereich des Übergangs zum Dichteinsatz 34, insbesondere auf der Seite des Schlitzes 44, abdichtet. Auf diese Weise ist sowohl zwischen dem Kabel 8 und dem Dichteinsatz 34 als auch zwischen den beiden Gehäuseteilen 10, 12 und schließlich auch zwischen dem Dichteinsatz 34 und den beiden Gehäuseteilen 10, 12 eine gute Abdichtung erzielt, so daß eine industrietaugliche Schutzart von IP65 oder höher erreicht werden kann.Finally, the second housing part 12 on the first housing part 10th fitted and screwed with this. In this case, the sealing insert 34, whose Dimensions in the initial state are slightly larger than the dimensions the cable passage 9, slightly compressed, so that he with bias on the side walls of the cable passage 9 abuts. By the angry Pressure is also the slot 44 of the sealing insert 34 compressed, so that There is a good seal there. The good seal is completed by the circumferential seal 24, which on the one hand between the two Housing parts seals and the other, due to the biasing lugs 26 in Combination with the pressure surfaces 32, in the area of transition to Seal insert 34, in particular on the side of the slot 44, seals. To this Way is both between the cable 8 and the sealing insert 34 as well between the two housing parts 10, 12 and finally between the Seal insert 34 and the two housing parts 10, 12 a good seal achieved so that an industrial grade of protection reaches IP65 or higher can be.

Gemäß einer nicht dargestellten Weiterbildung der Erfindung könnten die Stege 20 auch am zweiten Gehäuseteil 12 vorgesehen sein, um eine definiertere Vorspannung auf den Schlitz 44 aufbringen zu können. According to a not shown embodiment of the invention, the Webs 20 may also be provided on the second housing part 12 to a defined Pretension on the slot 44 can apply.
