Abstract

The invention relates to an electric plug-type connector (1) provided with a housing that comprises at least two parts (2, 3), whereby the first part (2) serves to accommodate plug pins or contact tubes and the second part (3) forms a protective covering that surrounds the contacting of the plug pins to the connecting leads, and radially protruding ribs (7) are provided on one of both parts (2). Said ribs, together with corresponding fillets (9) located on the other of the two parts (3), effect an axial fixing of both parts (2, 3) once both parts (2, 3) are turned with regard to one another. A spring-like stopping means (12) is provided between both parts (2, 3) and enables a rotary fixing. In order to create an anti-rotation element that, on the one hand, is rugged and always effects the same securing even when repeatedly opened and closed and, in the event of being unintentionally damaged, can be easily replaced. To this end, the spring-like stopping means (12) has a clamping area (14), which is clamped on one of both parts (2) and has a spring area (16). This spring area connects to the clamping area (14) in an axial direction of the plug-type connector (1), can move in a radial direction, and can be engaged (8) in a corresponding, outwardly open and radially accessible recess (21) located on the other part (3).

Description

Die vorliegende Erfindung bezieht sich auf eine elektrische Steckvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an electrical plug-in device according to the preamble of claim 1.

Solche Steckvorrichtungen sind beispielsweise aus der EP 0 921 605 A1 bekannt. Die beiden Gehäuseteile werden dort mittels eines Bajonettverschlusses miteinander verbunden und so axial und gegen Verdrehung gesichert. Die axiale Fixierung wird dabei mittels radial von einem der beiden Gehäuseteile abstehenden Rippen ermöglicht. Die Verdrehsicherung erfolgt durch ein Federelement, dass als Fortsetzung einer Rippe ausgebildet ist und welches in einer Ausnehmung eines Gehäuseteils einrastet. Als nachteilig dabei hat sich herausgestellt, dass durch mehrmaliges Öffnen und Schließen das Federelement, welches einstückig mit der Rippe ausgebildet ist und daher auch aus demselben Material gefertigt ist, relativ rasch verschleißt und einerseits an Federkraft verliert und andererseits ein am Federelement angeordneter Zahn, der die Relativbewegung der beiden Gehäuseteile in eingerasteter Stellung verhindert, sehr schnell abgeschoren wird, so dass eine ausreichende Verdrehsicherung nicht gegeben ist. Im Falle eines zu großen Verschleißes des Federelementes samt Zahn, ist die gesamte Steckvorrichtung unbrauchbar und zu ersetzten. Der Grund für den frühzeitigen Verschleiß des Federelementes sind die unterschiedliche Anforderungen an das Material der Steckvorrichtung als solche und an das Material des Federelementes. Das Material der Steckvorrichtung eignet sich nicht zur Herstellung eines federnden Bauteils mit relativ hoher Belastung.Such plug devices are known, for example, from EP 0 921 605 A1. The two housing parts are connected to each other there by means of a bayonet lock and thus secured axially and against rotation. The axial fixation is made possible by means of radially projecting from one of the two housing parts ribs. The rotation is effected by a spring element that is designed as a continuation of a rib and which engages in a recess of a housing part. The disadvantage here has been found that by repeated opening and closing the spring element, which is integrally formed with the rib and therefore is made of the same material, relatively quickly wears and loses one hand to spring force and on the other hand arranged on a spring element tooth, the Prevented relative movement of the two housing parts in the locked position, is sheared very quickly, so that a sufficient rotation is not given. In the case of excessive wear of the spring element together with the tooth, the entire plug-in device is unusable and replaced. The reason for the premature wear of the spring element are the different demands on the material of the plug-in device as such and on the material of the spring element. The material of the plug-in device is not suitable for producing a resilient component with a relatively high load.

Die US 5,743,763 zeigt ebenfalls eine ähnliche Steckvorrichtung, mit einem federartigen Anschlagmittel, welches die rotatorische Fixierung bewirkt. Die Zugänglichkeit zum Anschlagmittel zum Öffnen der Steckvorrichtung ist jedoch mühsam und anfällig gegen Verschmutzung.US 5,743,763 also shows a similar plug-in device, with a spring-like stop means, which causes the rotational fixation. However, the accessibility to the stop means for opening the plug-in device is cumbersome and prone to contamination.

Ziel der vorliegenden Erfindung ist es daher, diese Nachteile zu vermeiden und eine Steckvorrichtung der eingangs erwähnten Art vorzuschlagen, die eine Verdrehsicherung vorsieht, die einerseits robust ist und auch bei mehrmaligem Öffnen und Schließen stets dieselbe Sicherung bewirkt und im Falle eine unbeabsichtigten Zerstörung auch ein einfaches Austauschen ermöglicht.The aim of the present invention is therefore to avoid these disadvantages and to propose a plug-in device of the type mentioned, which provides an anti-rotation, on the one hand robust and always with repeated opening and closing causes the same backup and in case of unintentional destruction even a simple Exchange allows.

Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruchs 1 ermöglicht.This is made possible by the characterizing features of claim 1 according to the invention.

Durch die Einspannung des Federelementes in axialer Richtung erfolgt beim Verdrehen der beiden Gehäuseteile keine Beanspruchung des Federelementes auf Knickung. Ein Ausknicken des Federelementes ist somit nicht möglich. Die separate Anordnung des Federelementes ermöglicht auch die Verwendung eines speziell für die Haken- und Federtechnik abgestimmten Werkstoffes, wie in Anspruch 3 vorgeschlagen, der sich hinsichtlich Hydrolysebeständigkeit und Zugfestigkeit vom Werkstoff der restlichen Steckvorrichtung unterscheidet. Sollte das Federelement dennoch zerstört werden, so kann es einfach durch ein neues Federelement ersetzt werden. Die beiden Gehäuseteile der Steckvorrichtung können weiterverwendet werden.Due to the clamping of the spring element in the axial direction takes place when turning the two housing parts no stress on the spring element to buckling. A buckling of the spring element is thus not possible. The separate arrangement of the spring element also allows the use of a specially tailored for the hook and spring technology material, as proposed in claim 3, which differs in terms of resistance to hydrolysis and tensile strength of the material of the remaining plug-in device. Should the spring element nevertheless be destroyed, it can simply be replaced by a new spring element. The two housing parts of the plug-in device can continue to be used.

Das Merkmal des Anspruchs 2 ergibt einen sicheren Anschlag für eine Verdrehsicherung.The feature of claim 2 provides a secure stop for a rotation.

Die Merkmale des Anspruchs 4 und 5 ermöglichen eine einfache Fertigung der Aufnahme an einem der beiden Gehäuseteile. Die Aufnahme umschließt das Federelement auf drei Seiten. Die Übertragung von großen Kräften ist somit möglich und eine ausreichende Verdrehsicherung in jedem Fall gewährleistet.The features of claim 4 and 5 allow easy production of the recording on one of the two housing parts. The receptacle encloses the spring element on three sides. The transmission of large forces is thus possible and ensures sufficient rotation in each case.

Durch die Merkmale des Anspruchs 6 erfolgt eine Sicherung des Federelementes gegen Herausfallen aus der Aufnahme.Due to the features of claim 6 is a backup of the spring element against falling out of the recording.

Durch die Merkmale des Anspruchs 7 kann das Federelement sicher und einfach radial nach innen gepresst werden, wodurch die Verdrehsicherung gelöst wird.Due to the features of claim 7, the spring element can be safely and easily pressed radially inward, whereby the rotation is achieved.

Fig. 1 zeigt eine erfindungsgemäße Steckvorrichtung 1 mit einem ersten Gehäuseteil 2 und einem zweiten Gehäuseteil 3. Der erste Gehäuseteil 2 dient zur Aufnahme von Steckerstiften (nicht gezeichnet), welche in den dafür vorgesehenen Steckerkanälen 4 (Fig.4) befestigbar sind. Alternativ dazu kann der erste Gehäuseteil 2 auch zur Aufnahme von Kontaktbuchsen dienen. Der Begriff Steckvorrichtung umfasst somit sowohl Stecker als auch Kupplungen und Steckdosen. Der erste Gehäuseteil 2 weist weiters einen schmalen Flanschabschnitt 5 auf, der beim Zusammenstecken der beiden Gehäuseteile 2,3 den Grad der Überlappung bestimmt. In zusammengesteckten Zustand der beiden Gehäuseteile 2,3 überlappen sich diese jeweils in einem Bereich 6 (erster Gehäuseteil 2) und einem Bereich 8 (zweiter Gehäuseteil 3). Im Überlappungsbereich 6 des einen Gehäuseteils 2 sind radial abstehende Rippen 7 (Fig.4) angeordnet.1 shows a plug-in device 1 according to the invention with a first housing part 2 and a second housing part 3. The first housing part 2 serves to receive plug pins (not shown) which can be fastened in the plug channels 4 provided for this purpose (FIG. Alternatively, the first housing part 2 can also serve to receive contact sockets. The term plug-in device thus includes both plugs and couplings and sockets. The first housing part 2 further has a narrow flange section 5, which upon mating of the two Housing parts 2.3 determines the degree of overlap. In the assembled state of the two housing parts 2, 3, these overlap in each case in a region 6 (first housing part 2) and an area 8 (second housing part 3). In the overlapping region 6 of the one housing part 2, radially projecting ribs 7 (FIG. 4) are arranged.

Der zweite Gehäuseteil 3 dient zur Ummantelung der Kontaktierung der Steckerstifte bzw. Kontaktbuchsen mit den elektrischen Anschlussleitungen. Im Überlappungsbereich 8, der ausgestellt ist, um den Überlappungsbereich 6 des ersten Gehäuseteils 2 umschließen zu können, sind Schlitze bzw. Ausnehmungen 21 vorgesehen, welche einerseits der leichteren Entformung des Spritzgussteils dienen und andererseits dem Öffnen der Verdrehsicherung, wie an späterer Stelle noch genauer ausgeführt wird. An der Innenseite des Überlappungsbereiches 8 sind radial nach innen abstehende Stege 9 angeordnet, die mit den Rippen 7 des ersten Gehäuseteils 2 zusammenarbeiten und so die axiale Fixierung ermöglichen. Es ist klar ersichtlich, dass die Rippen 7 auch am zweiten Gehäuseteil 3 und die Stege 9 am ersten Gehäuseteil 2 angeordnet sein können.The second housing part 3 serves to encase the contacting of the plug pins or contact sockets with the electrical connection lines. Slits or recesses 21 are provided in the overlapping area 8, which is shown to be able to enclose the overlapping area 6 of the first housing part 2, which on the one hand serve for easier demoulding of the injection molded part and, on the other hand, for opening the anti-rotation lock, as explained in more detail later becomes. On the inside of the overlap region 8 radially inwardly projecting webs 9 are arranged, which cooperate with the ribs 7 of the first housing part 2 and thus allow the axial fixation. It is clear that the ribs 7 can also be arranged on the second housing part 3 and the webs 9 on the first housing part 2.

Der erste Gehäuseteil 2 weist des weiteren zwei im Querschnitt im wesentlichen L-förmige, sich in axialer Richtung der Steckvorrichtung 1 erstreckende Stege 10 auf, die gemeinsam mit dem Mantel des Gehäuseteils 2 eine Aufnahme 11 (Fig.3) begrenzen. In diese Aufnahme 11 ist ein Federelement 12 steckbar, dass einen nach außen gerichteten Zahn 13 aufweist. Das Federelement 12 ist in axialer Richtung (in Fig.2 von oben) in die Aufnahme 11 schiebbar, wobei es dabei in der Aufnahme 11 mittels Presssitz fixiert ist. Der Presssitz ist dabei so fest, dass das Federelement 12 im unteren Bereich der Aufnahme 11 praktisch eingespannt ist, und im oberen Bereich in radialer Richtung der Steckvorrichtung 1 federn kann. Ein Bereich 14 des Federelements 12 ist dabei zwischen den in Umfangsrichtung des Gehäuseteils 2 verlaufenden Armen 15 der im Querschnitt L-förmigen Stege 10 und dem Mantel des Gehäuseteils 2 geklemmt, der andere Bereich 16 ist zwischen den beiden Armen 15 positioniert.The first housing part 2 further comprises two cross-sectionally substantially L-shaped, in the axial direction of the plug-in device 1 extending webs 10, which define together with the shell of the housing part 2 a receptacle 11 (Figure 3). In this receptacle 11 is a spring element 12 can be plugged that has an outwardly directed tooth 13. The spring element 12 is in the axial direction (in Figure 2 from above) into the receptacle 11 slidable, wherein it is fixed in the receptacle 11 by means of press fit. The interference fit is so strong that the spring element 12 is practically clamped in the lower region of the receptacle 11, and in the upper region in the radial direction of the plug-in device 1 can spring. A region 14 of the spring element 12 is between the extending in the circumferential direction of the housing part 2 arms 15 of cross-sectionally L-shaped webs 10th and the shell of the housing part 2 clamped, the other area 16 is positioned between the two arms 15.

Das Federelement 12 ist aus einem speziell für die Haken und Federtechnik geeignetem Kunststoff hergestellt, der sich vom Kunststoff der Steckvorrichtung hinsichtlich seiner physikalischen Eigenschaften unterscheidet. Prinzipiell ist es auch möglich ein Metallfederplättchen als Federelement zu verwenden bzw. andere, gute Federeigenschaften bei ausreichender Festigkeit aufweisendes Federmaterial einzusetzen. Das Federelement 12 weist, wie bereits erwähnt, einen zahnartigen Vorsprung 13 auf, der in zusammengebauten Zustand der beiden Gehäuseteile 2,3 die Verdrehsicherung bewirkt. Der Zahn 13 ist mit einer Anlaufschräge 13a versehen, welche eine Vertiefung 13b aufweist.The spring element 12 is made of a specially suitable for the hook and spring technology plastic, which differs from the plastic of the connector with respect to its physical properties. In principle, it is also possible to use a metal spring plate as a spring element or to use other, good spring properties with sufficient strength exhibiting spring material. The spring element 12 has, as already mentioned, a tooth-like projection 13, which causes the rotation in the assembled state of the two housing parts 2.3. The tooth 13 is provided with a run-on slope 13a, which has a recess 13b.

Die Funktionsweise der Steckvorrichtung ist wie folgt:The operation of the plug-in device is as follows:

Die beiden Gehäuseteile 2,3 werden in axialer Richtung ineinandergeschoben, so dass Überlappungsbereich 8 Überlappungsbereich 6 umschließt. Der Flanschabschnitt 5 dient dabei als Begrenzung des axialen Zusammenschiebens. Die vom Überlappungsbereich 8 des zweiten Gehäuseteils 3 nach innen abstehenden Stege 9 erlauben dabei das axiale Zusammenschieben der beiden Gehäuseteile 2,3 nur in einer definierten Position zueinander.The two housing parts 2, 3 are pushed into one another in the axial direction, so that the overlapping area 8 encloses the overlapping area 6. The flange portion 5 serves as a limitation of the axial Zusammenschiebens. The protruding from the overlap region 8 of the second housing part 3 webs 9 allow the axial collapse of the two housing parts 2.3 only in a defined position to each other.

Nach dem Zusammenschieben der beiden Gehäuseteile 2,3 werden diese gegeneinander verdreht, wobei die Stege 9 das Verdrehen lediglich in eine Richtung ermöglichen. Dadurch werden die Rippen 7 und die Stege 9 unter bzw. übereinander positioniert, so dass eine axiale Bewegung der beiden Gehäuseteile 2,3 nicht mehr möglich ist. Im Zuge der Drehung in die vorgegebene Richtung wird das Federelement 12 in seinem oberen, frei federnden Bereich durch den Steg 17 in Richtung des Mantels des Gehäuseteils 2 gedrückt. Nach dem das Federelement 12 den Steg 17 im Zuge der Drehung passiert hat, springt es durch die Federwirkung radial nach außen, in eine Ausnehmung 21. Dabei stützt sich der Zahn 13 mit seiner Stirnseite am Steg 17 ab. Eine Verdrehung in Richtung des Steges 17 ist somit nicht mehr möglich. Eine Verdrehung in die entgegengesetzte Richtung ist aufgrund des Steges 9a nicht möglich, da dieser stirnseitig mit der Rippe 7a aufeinandertrifft.After pushing together of the two housing parts 2, 3, these are rotated against each other, wherein the webs 9 allow twisting in one direction only. As a result, the ribs 7 and the webs 9 are positioned below or above one another, so that an axial movement of the two housing parts 2, 3 is no longer possible. In the course of the rotation in the predetermined direction, the spring element 12 is pressed in its upper, freely resilient region through the web 17 in the direction of the jacket of the housing part 2. After the spring element 12 has passed the web 17 in the course of the rotation, it jumps by the spring action radially outwards, in a recess 21. In this case, the tooth 13 is supported by his Front side on the web 17 from. A rotation in the direction of the web 17 is thus no longer possible. A rotation in the opposite direction is not possible due to the web 9a, since this frontally with the rib 7a meets one another.

Der Steg 17 ist dabei so ausgeführt, dass er schräg nach innen verläuft um während der Drehung das Federelement 12 langsam nach innen zu drücken.The web 17 is designed so that it extends obliquely inward during the rotation to press the spring element 12 slowly inwards.

Um die Verdrehsicherung zu lösen ist es nur erforderlich, das Federelement 12 mit einem spitzen Gegenstand durch die Ausnehmung 21 hindurch nach innen zu drücken. Der spitze Gegenstand wird dabei an der Anlaufschräge 13b angesetzt und gleitet über diese in die Vertiefung 13a, wo er festen Halt findet und das Federelement radial nach innen presst. Gleichzeitig muß der erste Gehäuseteil 2 in Richtung des Steges 17 verdreht werden.To solve the rotation, it is only necessary to press the spring element 12 with a pointed object through the recess 21 through inside. The pointed object is attached to the run-on slope 13b and slides over it into the recess 13a, where it finds firm hold and presses the spring element radially inward. At the same time, the first housing part 2 must be rotated in the direction of the web 17.
