- the ring forms a controlled resistance in both directions of rotation.
- connection In the known types of connection, the user is not clear whether the connected with it by a quick connection technology, in which a connector is made by simply axial mating the connector parts, the connected connector is properly locked because he receives no clear feedback.
- the object of the invention is to propose a possibility in which the connecting element formed as a locking sleeve has at least one defined unlocking and locking position with respect to the supporting housing, the reaching or leaving of these positions being preferably haptic or acoustically perceivable by the user.
- This object is achieved by an electrical connector part and an electrical connector system with the features of the two subordinate claims 1 and 5. Further advantageous embodiments can be found in the respective dependent claims.
- the connector part according to the invention on a rotation, which consists of at least one externally fixed to the plug housing part spring element and at least one associated therewith, on the inside of the locking sleeve locking latch. It allows at least when snapping the spring element into the latching haptic and acoustic perception.
- the spring element is intended to ensure that the locking sleeve does not unintentionally twist in the opened state.
- blind plugging is easier for the user, because he must visually check whether the locking sleeve is in the correct position.
- the spring element is preferably formed by a projectingly bent Blattfederzu- cut and is immovably in an outer recess of the plug housing part, wherein the projection of the leaf spring blank protrudes beyond the outer recess and can engage in the locking latch of the locking sleeve in the locking position of the connector part.
- the spring element on the inside of the locking sleeve facing the locking lug, which engages in the unlocked state of the locking sleeve and in the locked state of the locking sleeve in a respective designated first detent pocket or second detent pocket. This can be clearly distinguished between the locked and unlocked state and also allows different locking forces during operation.
- a guide curve is arranged, which has a contour which under such circumstances the spring element Spring tension holds that the locking sleeve can only be rotated by external force on the locking sleeve.
- the contour between the first latching pocket and the second latching pocket is flat in a first region and steeply rising in a second region near the second latching pocket, wherein the first region is longer than the second region.
- the locking lug is engaged in the first catch pocket.
- the contour in the first area is flat so as not to produce premature noise, such as clicking.
- solely by leaving the first latching pocket a spring tension is present, which is sufficiently pronounced that the locking sleeve can not turn by itself.
- the contour in the second region is rising sharply, so that the spring element is about to be completely compressed. If the locking sleeve continues to rotate, a noise (click sound) is produced and the connector part is properly locked to the mating connector part and in position.
- the locking sleeve is held in the axial direction by means of engaging in an inner circumferential groove of the locking sleeve and in an outer circumferential groove of the plug housing housing corrugated spring on the plug housing part and is supported against the plug housing part and / or the locking sleeve.
- the corrugated spring is held against rotation in the outer circumferential groove of the plug part housing or in the inner circumferential groove of the locking sleeve. If the corrugated spring is fixed in the circumferential direction in the outer peripheral groove of the plug-part housing, it engages rotatably in the inner circumferential groove of the locking sleeve.
- the connector part has a corrugated spring, which is open in the circumferential direction and has a spring gap.
- a corrugated spring which is open in the circumferential direction and has a spring gap.
- the corrugated spring has in the axial direction wave crests and intervening wave troughs.
- the spring gap of the corrugator can change in its width when the corrugated spring is subjected to pressure in the axial direction, ie the height of the corrugation peaks or the depth of the troughs changes.
- the height of the wave crests and the depth of the wave troughs are greater than a groove width of the outer circumferential groove of the plug part housing and the inner circumferential groove of the locking sleeve. As a result, it rests on both edges of the outer circumferential groove of the plug-part housing and the inner circumferential groove with the same clamping force. In this case, dimensional tolerances of the corrugated spring itself play no role. In any position of the locking sleeve relative to the connector part housing acts a sufficient clamping force, which complicates an undesirable change in position of the locking sleeve relative to the connector housing part.
- the system requires no additional friction brake, for example in the form of an elastic ring element.
- the locking sleeve on the plug housing part is both in the locking process as well as the unlocking process from the beginning of a clamping force available.
- the outer circumferential groove of the plug part housing or the inner circumferential groove of the locking sleeve at least one positioning web for the corrugated spring, which is preferably arranged on a side edge of the outer circumferential groove or a side edge of the inner circumferential groove. It goes without saying that such a bridge must not be present in both grooves, since this would not allow twisting of the locking sleeve on the plug part housing. Instead of being arranged on the side flanks of one of the two grooves, the positioning web can also protrude from the bottom of these grooves.
- the corrugated spring is preferably aligned with respect to the connector part housing or the locking sleeve in such a way that the positioning web passes through the spring gap and thus fixes the wave spring in a manner secured against rotation.
- the corrugated spring is advantageously oriented relative to the connector part housing or the locking sleeve in such a way that the at least one positioning web extends in a corrugation valley of the corrugated spring. Also in this way, the corrugated spring can be secured against rotation in the circumferential direction, free of play or with play, in the inner circumferential groove of the locking sleeve or in the outer circumferential groove of the connector housing.
- the positioning web in the trough may also preferably form a compression limiting web for the wave spring, which limits an axial compression travel of the wave spring.
- a compression limiting web in a wave trough may be present in addition to a positioning web passing through the spring gap.
- the side edge of the inner circumferential groove of the locking sleeve or the side edge of the outer circumferential groove of the connector part housing is formed wave-shaped, wherein the contour the side edge is preferably adapted to the shape of the wave spring.
- the wave contour is, of course, realized in that inner peripheral groove of the locking sleeve or the outer circumferential groove of the plug part housing in which the positioning web described above is not formed, which holds the wave spring against rotation.
- the at least one locking means of the locking sleeve and the at least one counter locking means of the Schmidtverriegelungsabiteses are formed as full thread, circumferentially segmented partial thread or in the manner of a bayonet lock or a bayonet lock.
- the locking sleeve and the counter-locking section engage at least partially axially into one another in the case of the plug-in connector part mating with the mating plug part, and can be releasably fixed to one another by turning the locking sleeve.
- the at least one locking means of the locking sleeve outside or inside of the locking sleeve can be formed.
- the at least one complementarily executed counter-locking means is correspondingly mutually formed on the counter-locking portion of the mating connector part.
- the connector part has on the locking sleeve and the plug housing housing rotation stops, which rotate the Limit movement of the locking sleeve relative to the plug housing.
- the at least one locking means of the locking sleeve and the at least one counter locking means of Schmidtverriegelungsabiteses are not formed as full thread, but as circumferentially segmented partial thread or like a bayonet lock or a bayonet lock.
- the rotational stops of the locking sleeve are preferably formed by axially extending longitudinal walls of a sleeve inner recess and the rotational stops of the plug member housing are preferably formed by longitudinal flanks of a radially projecting outer housing pin.
- the circumferential width of the sleeve inner recess is significantly larger than the corresponding width of the housing outer pin. They are preferably selected such that an unlocking position and a locking position are realized, between the locking sleeve can be rotated. The unlocking position and the locking position are separated by a typical angle of rotation of about 30 to 100 degrees.
- the electrical connector system according to the invention having a connector part having a rotatably mounted on a plug housing housing locking sleeve, and having a mating connector part having a locking sleeve associated formed on a mating connector housing tubular Gegenverriegelungsabrough for releasably securing the connector part to the mating connector part comprises a connector part with one or more of the features described above.

Elektrische Steckverbinderteile zum Verbinden mit einem Gegensteckerteil und elektrische Steckverbindungssysteme, umfassend ein Steckverbinderteil und ein Gegensteckerteil, der eingangs genannten Art, sind aus dem Stand der Technik bekannt. Beispielhaft wird auf die Druckschriften DE 20 2005 000 229 U1 und DE 10 2005 026 148 B4 verwiesen. Electrical connector parts for connection to a mating connector part and electrical connector systems, comprising a connector part and a mating connector part, of the type mentioned, are known from the prior art. By way of example, reference is made to the publications DE 20 2005 000 229 U1 and DE 10 2005 026 148 B4.
Die DE 10 2005 026 148 B4 offenbart eine Steckverbinderkupplung, insbesondere für mehrpolige elektrische Leitungsverbindungen, bestehend aus einer ersten Kupplungshälfte, welche wenigstens ein Kupplungsgehäuse, einen darin un- tergebrachten Kontaktträger samt Kontaktelementen und einen den Kontaktträ- ger und gegebenenfalls dessen Kontaktelemente zumindest übereinen Teil ihrer axialen Länge hin umgreifenden, mit einem Außengewinde zum wahlweisen Auf- schrauben einer drehbar mit einer zweiten Kupplungshälfte gekoppelten Über- wurfmutter oder zum Anschluss eines drehbar mit einer zweiten Kupplungshälfte gekoppelten, mit Mitteln zur Herbeiführung einer Schnellverriegelung ausgestat- teten Verbindungselementes geeigneten Bereich des Kupplungsgehäuses um- fasst. Dabei sind in Verbindung mit einem gewindelosen Verbindungselement der zweiten Kupplungshälfte an einer außerhalb des Außengewindes befindlichen Teillänge des mit einem Außengewinde versehenen Bereiches des ersten Kupplungsgehäuses Verriegelungsmittel zur Schnellverriegelung ausgebildet, denen komplementäre Gegenstücke am Verbindungselement zugeordnet sind, wobei das Verbindungselement der zweiten Kupplungshälfte vorzugsweise von einer gewindelosen Hülse gebildet ist und vermittels einer gegen das Gehäuse der zweiten Kupplungshälfte abgestützten Belastungsfeder, insbesondere einer als Wellfeder ausgebildeten Belastungsfeder in axialer Richtung gehalten, ins- besondere spielfrei gehalten ist. Die Wellfeder ist dabei einerseits gegen eine Stirnfläche des Gehäuses der zweiten Kupplungshälfte abgestützt und wirkt andererseits mit einem gegen eine Schulter in der Innenumfangswandung des als Hülse ausgebildeten Verbindungselementes der zweiten Kupplungshälfte abgestützten Auflagering zusammen, wobei die Stirnfläche des Gehäuses und die Schulter in der Innenumfangswandung der Hülse eine Außenumfangsnut des Gehäuses bilden und begrenzen. DE 10 2005 026 148 B4 discloses a connector coupling, in particular for multi-pole electrical line connections, consisting of a first coupling half, which at least one coupling housing, a contact carrier therein including contact elements and a Kontaktträ- ger and optionally its contact elements at least over a part of their axial length around, with an external thread for selectively unscrewing a rotatably coupled to a second coupling half union nut or for connecting a rotatably coupled to a second coupling half, equipped with means for achieving a quick locking connection member suitable region of the coupling housing um- summarizes. In this case, in connection with a non-threaded connecting element of the second coupling half on a part of the external thread located outside of the external thread portion of the first coupling housing locking means for quick locking formed, which complementary counterparts are assigned to the connecting element, wherein the connecting element of the second coupling half preferably from a threadless Sleeve is formed and held by means of a supported against the housing of the second coupling half loading spring, in particular a trained as a wave spring loading spring in the axial direction, in particular is kept free of play. The corrugated spring is supported on the one hand against an end face of the housing of the second coupling half and on the other hand cooperates with a bearing against a shoulder in the inner peripheral wall of the sleeve formed as a connecting element of the second coupling half supporting ring, wherein the end face of the housing and the Shoulder in the inner peripheral wall of the sleeve form and limit an outer circumferential groove of the housing.
Als nachteilig wird bei dieser bekannten Steckverbinderkupplung angesehen, dass zum einen das Verbindungselement, das in axialer Richtung von der Belastungsfeder spielfrei an dem Kupplungsgehäuse gehalten ist, in Umfangsrichtung keine klar definierten Stellungen gegenüber dem Kupplungsgehäuse der zweiten Kupplungshälfte aufweist, d.h. beliebige Stellungen einnehmen kann und zum anderen, dass eine zusätzliches Teil benötigt wird, um die Außenumfangsnut des Gehäuses zu bilden. A disadvantage is considered in this known connector coupling that on the one hand, the connecting element, which is held in the axial direction of the loading spring play on the clutch housing, in the circumferential direction has no clearly defined positions relative to the clutch housing of the second coupling half, i. and that an additional part is needed to form the outer circumferential groove of the housing.
Aus der US 7625 226 B1 ist ein federnder Ring aus einem Band aus Flachmetall bekannt, der in einem Ringraum zwischen einer Verriegelungshülse einem darin über ein Gewinde aufgenommenes hülsenförmiges Steckerelement einliegt und mit über den Umfang verteilten Nasen in der Innenwand der Verriegelungshülse einliegt und dazwischen sich abwechselnd an der Außenwand des Steckerelements und der Innenwand der Verriegelungshülse abstützt. Der Ring bildet bei der Drehung einen kontrollierten Widerstand in beide Drehrichtungen. From US 7625 226 B1, a resilient ring made of a strip of flat metal is known, which rests in an annular space between a locking sleeve therein received via a threaded sleeve-shaped connector element and rests with circumferentially distributed lugs in the inner wall of the locking sleeve and alternately therebetween supported on the outer wall of the male member and the inner wall of the locking sleeve. The ring forms a controlled resistance in both directions of rotation.
Bei den bekannten Anschlussarten ist dem Benutzer nicht eindeutig klar, ob der von ihm mit einer Schnellanschlusstechnik, bei der eine Steckverbindung durch einfaches axiales Zusammenstecken der Steckverbinderteile hergestellt wird, der angeschlossene Steckverbinder auch richtig verriegelt ist, da er keine eindeutige Rückmeldung erhält. In the known types of connection, the user is not clear whether the connected with it by a quick connection technology, in which a connector is made by simply axial mating the connector parts, the connected connector is properly locked because he receives no clear feedback.
Ausgehend von dem genannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Möglichkeit vorzuschlagen, bei der das als Verriegelungshülse ausgebildete Verbindungselement zumindest eine definierte Entriege- lungs- und Verriegelungsstellung bezüglich dem tragenden Gehäuse besitzt, wobei das Erreichen oder Verlassen dieser Stellungen vorzugsweise haptisch oder akustisch vom Anwender wahrnehmbar ist. Diese Aufgabe wird erfindungsgemäß durch ein elektrisches Steckverbinderteil und ein elektrisches Steckverbindungssystem mit den Merkmalen der beiden ne- bengeordneten Ansprüche 1 und 5 gelöst. Weitere vorteilhafte Ausführungsformen sind den jeweiligen rückbezogenen Ansprüchen zu entnehmen. Based on the cited prior art, the object of the invention is to propose a possibility in which the connecting element formed as a locking sleeve has at least one defined unlocking and locking position with respect to the supporting housing, the reaching or leaving of these positions being preferably haptic or acoustically perceivable by the user. This object is achieved by an electrical connector part and an electrical connector system with the features of the two subordinate claims 1 and 5. Further advantageous embodiments can be found in the respective dependent claims.
Danach weist das erfindungsgemäße Steckverbinderteil eine Verdrehsicherung auf, die von wenigsten einem an dem Steckerteilgehäuse außen festgelegten Federelement und mindestens einer diesem zugeordneten, innen an der Verrie- gelungshülse ausgebildeten Rastfalle besteht. Sie ermöglicht zumindest beim Einrasten des Federelements in die Rastfalle eine haptische und akustische Wahrnehmung. Das Federelement soll gewährleisten, dass die Verriegelungs- hülse sich im geöffneten Zustand sich nicht ungewollt verdreht. Dadurch ist das sogenannt„Blindstecken“ für den Benutzer einfacher, denn er muss optisch überprüfen, ob die Verriegelungshülse auf der richtigen Position ist. Das Fe- derelement ist vorzugsweise von einem vorspringend gebogenen Blattfederzu- schnitt gebildet und liegt in einer Außenvertiefung des Steckerteilgehäuses unverschiebbar ein, wobei der Vorsprung des Blattfederzuschnittes über die Außenvertiefung vorsteht und so in die Rastfalle der Verriegelungshülse in der Ver- riegelungsstellung des Steckverbinderteils eingreifen kann. Thereafter, the connector part according to the invention on a rotation, which consists of at least one externally fixed to the plug housing part spring element and at least one associated therewith, on the inside of the locking sleeve locking latch. It allows at least when snapping the spring element into the latching haptic and acoustic perception. The spring element is intended to ensure that the locking sleeve does not unintentionally twist in the opened state. Thus, the so-called "blind plugging" is easier for the user, because he must visually check whether the locking sleeve is in the correct position. The spring element is preferably formed by a projectingly bent Blattfederzu- cut and is immovably in an outer recess of the plug housing part, wherein the projection of the leaf spring blank protrudes beyond the outer recess and can engage in the locking latch of the locking sleeve in the locking position of the connector part.
Vorzugsweise weist das Federelement eine der Innenseite der Verriegelungshülse zugewandte Rastnase auf, die im unverriegelten Zustand der Verriegelungshülse und im verriegelten Zustand der Verriegelungshülse in eine jeweils dafür vorgesehene erste Rasttasche oder zweite Rasttasche einrastet. Damit kann eindeutig zwischen dem verriegelten und unverriegelten Zustand unterschieden werden und ermöglicht außerdem verschiedene Einrastkräfte bei der Bedienung. Preferably, the spring element on the inside of the locking sleeve facing the locking lug, which engages in the unlocked state of the locking sleeve and in the locked state of the locking sleeve in a respective designated first detent pocket or second detent pocket. This can be clearly distinguished between the locked and unlocked state and also allows different locking forces during operation.
Um ein mögliches Lösen bei Vibrationen zu verhindern, ist gemäß einerweiteren vorteilhaften Ausbildung des erfindungsgemäßen Steckverbinderteils auf der Innenseite der Verrieglungshülse zwischen der ersten Rasttasche im unverriegelten Zustand und der zweiten Rasttasche im verriegelten Zustand eine Führungskurve angeordnet, die eine Kontur aufweist, die das Federelement derart unter Federspannung hält, dass die Verriegelungshülse nur unter externer Krafteinwir- kung auf die Verriegelungshülse verdrehbar ist. In order to prevent a possible loosening in vibration, according to a further advantageous embodiment of the connector part according to the invention on the inside of the Verrieglungshülse between the first latching pocket in the unlocked state and the second latching bag in the locked state, a guide curve is arranged, which has a contour which under such circumstances the spring element Spring tension holds that the locking sleeve can only be rotated by external force on the locking sleeve.
In einer besonders bevorzugten Ausbildung der Erfindung ist die Kontur zwischen der ersten Rasttasche und der zweiten Rasttasche in einem ersten Bereich flach und in einem zweiten Bereich nahe der zweiten Rasttasche steil ansteigend ausgebildet, wobei der erste Bereich länger ist als der zweite Bereich. Im unverriegelten Zustand ist die Rastnase in der ersten Rasttasche eingerastet. Beginnt der Benutzer mit der Verdrehung der Verriegelungshülse, ist die Kontur im ersten Bereich flach ausgelegt, um kein vorzeitiges Geräusch, beispielsweise Klicken, zu erzeugen. Jedoch ist allein durch das Verlassen der ersten Rasttasche eine Federspannung vorhanden, die ausreichend stark ausgeprägt ist, dass die Verriegelungshülse sich nicht von allein verdrehen kann. Kurz vor der dem verriegelten Zustand ist die Kontur im zweiten Bereich stark ansteigen, so dass das Federelement kurz davor ist, vollständig komprimiert zu werden. Wird die Verriegelungshülse weiter gedreht entsteht ein Geräusch (Klick-Geräusch) und der das Steckverbinderteil ist mit dem Gegensteckerteil richtig verriegelt und auf Position. In a particularly preferred embodiment of the invention, the contour between the first latching pocket and the second latching pocket is flat in a first region and steeply rising in a second region near the second latching pocket, wherein the first region is longer than the second region. In the unlocked state, the locking lug is engaged in the first catch pocket. When the user begins twisting the locking sleeve, the contour in the first area is flat so as not to produce premature noise, such as clicking. However, solely by leaving the first latching pocket a spring tension is present, which is sufficiently pronounced that the locking sleeve can not turn by itself. Shortly before the locked state, the contour in the second region is rising sharply, so that the spring element is about to be completely compressed. If the locking sleeve continues to rotate, a noise (click sound) is produced and the connector part is properly locked to the mating connector part and in position.
Gemäß einer weiteren Ausbildung des elektrischen Steckverbinderteils ist die Verriegelungshülse mittels einer in eine Innenumfangsnut der Verriegelungshülse und in eine Außenumfangsnut des Steckerteilgehäuses eingreifenden Wellfeder in axialer Richtung spielfrei auf dem Steckerteilgehäuse gehalten und stützt sich gegen das Steckerteilgehäuse und/oder die Verriegelungshülse ab. Erfindungsgemäß ist vorgesehen, dass die Wellfeder in der Außenumfangsnut des Steckerteilgehäuses oder in der Innenumfangsnut der Verriegelungshülse verdrehsicher aufgenommen ist. Liegt die Wellfeder in Umfangsrichtung lagefixiert in der Außenumfangsnut des Steckerteilgehäuses ein, so greift diese drehbar in die Innenumfangsnut der Verriegelungshülse ein. Im anderen Fall, d.h. wenn die Wellfeder in Umfangsrichtung lagefixiert in die Innenumfangsnut der Verriegelungshülse aufgenommen ist, greift diese drehbar in die Außenumfangsnut des Steckerteilgehäuses ein. In beiden Fällen ist sie in der jeweiligen Nut, in die die Wellfeder drehbar eingreift, nur mit Drehwiderstand verdrehbar, der von der axialen Federkraft der Wellfeder und von deren Vorspannung in der In- nenumfangsnut der Verriegelungshülse und/oder in der Außenumfangsnut des Steckerteilgehäuses bestimmt ist. Damit besitzt die Wellfeder, die die Verriegelungshülse und das Steckerteilgehäuse zusammen hält, einen eingeschränkten Freiheitsgrad in ihrer Beweglichkeit gegenüber dem Steckerteilgehäuse bzw. der Verriegelungshülse. Dies ist Grundvoraussetzung für eine definierte Entriege- lungs- und/oder Verriegelungsstellung. Material- und prozessbedingt weisen das Steckerteilgehäuse und die Verriegelungshülse Herstellungstoleranzen in ihren Maßen auf, die durch die Wellfeder ausgeglichen werden, indem die Wellfeder mit Vorspannung, d.h. komprimiert in die Außenumfangsnut des Steckerteilgehäuses und in die Innenumfangsnut der Verriegelungshülse eingesetzt ist. According to a further embodiment of the electrical connector part, the locking sleeve is held in the axial direction by means of engaging in an inner circumferential groove of the locking sleeve and in an outer circumferential groove of the plug housing housing corrugated spring on the plug housing part and is supported against the plug housing part and / or the locking sleeve. According to the invention, it is provided that the corrugated spring is held against rotation in the outer circumferential groove of the plug part housing or in the inner circumferential groove of the locking sleeve. If the corrugated spring is fixed in the circumferential direction in the outer peripheral groove of the plug-part housing, it engages rotatably in the inner circumferential groove of the locking sleeve. In the other case, ie when the corrugated spring is fixed in the circumferential direction in the inner circumferential groove of the locking sleeve, this engages rotatably in the outer peripheral groove of the connector part housing. In both cases, it is rotatable in the respective groove in which the wave spring rotatably, only with rotational resistance of the axial spring force of the corrugated spring and its bias in the inner circumferential groove of the locking sleeve and / or in the outer circumferential groove of the connector part housing is determined. Thus, the corrugated spring, which holds the locking sleeve and the connector housing together, a limited degree of freedom in their mobility relative to the plug housing part or the locking sleeve. This is a basic prerequisite for a defined unlocking and / or locking position. Material and process conditionally have the plug housing part and the locking sleeve manufacturing tolerances in their dimensions, which are compensated by the wave spring by the corrugated spring with bias, ie compressed into the outer circumferential groove of the plug housing part and in the inner circumferential groove of the locking sleeve is inserted.
Vorzugweise weist das Steckverbinderteil eine Wellfeder auf, die in Umfangs- richtung offen ausgebildet ist und einen Federspalt besitzt. Damit ist diese in Umgangsrichtung nachgiebig ausgebildet und kann somit einfach in die Innenumfangsnut der Verriegelungshülse und in der Außenumfangsnut des Ste- ckerteilgehäuses eingeführt werden, um die Verriegelungshülse und das Ste- ckerteilgehäuse zusammen zu halten. Die Wellfeder besitzt in axialer Richtung Wellenberge und dazwischen liegende Wellentäler. Der Federspalt der Wellfe- der kann sich in seiner Breite verändern, wenn die die Wellfeder in axialer Richtung Druck beaufschlagt wird, d.h. sich die Höhe der Wellenberge bzw. die Tiefe der Wellentäler verändert. Die Höhe der Wellenberge und die Tiefe der Wellentäler sind dabei größer als eine Nutbreite der Außenumfangsnut des Steckerteilgehäuses und der Innenumfangsnut der Verriegelungshülse. Dadurch liegt er an beiden Kanten der Außenumfangsnut des Steckerteilgehäuses und der In- nenumfangsnut mit gleicher Spannkraft an. Dabei spielen Maßtoleranzen der Wellfeder selbst keine Rolle. In jeder Position der Verriegelungshülse gegenüber dem Steckerteilgehäuse wirkt eine ausreichende Spannkraft, die ein uner- wünschtes Lageveränderung der Verriegelungshülse gegenüber dem Steckerteilgehäuse erschwert. Solange die Vorspannung der Wellfeder größer ist als die Belastung aus einer Schwingungsamplitude, benötigt das System keine weitere Reibbremse, beispielsweise in Form eines elastischen Ringelementes. Beim Verdrehen der Verriegelungshülse auf dem Steckerteilgehäuse steht sowohl beim Verriegelungsvorgang wie auch beim Entriegelungsvorgang von Beginn an eine Spannkraft zur Verfügung. Preferably, the connector part has a corrugated spring, which is open in the circumferential direction and has a spring gap. Thus, this is resilient in the circumferential direction and thus can be easily inserted into the inner circumferential groove of the locking sleeve and in the outer circumferential groove of the connector housing to hold the locking sleeve and the connector housing together. The corrugated spring has in the axial direction wave crests and intervening wave troughs. The spring gap of the corrugator can change in its width when the corrugated spring is subjected to pressure in the axial direction, ie the height of the corrugation peaks or the depth of the troughs changes. The height of the wave crests and the depth of the wave troughs are greater than a groove width of the outer circumferential groove of the plug part housing and the inner circumferential groove of the locking sleeve. As a result, it rests on both edges of the outer circumferential groove of the plug-part housing and the inner circumferential groove with the same clamping force. In this case, dimensional tolerances of the corrugated spring itself play no role. In any position of the locking sleeve relative to the connector part housing acts a sufficient clamping force, which complicates an undesirable change in position of the locking sleeve relative to the connector housing part. As long as the bias of the wave spring is greater than the load from a vibration amplitude, the system requires no additional friction brake, for example in the form of an elastic ring element. At the Twisting the locking sleeve on the plug housing part is both in the locking process as well as the unlocking process from the beginning of a clamping force available.
In einer vorteilhaften Ausführungsform weist bei dem Steckverbinderteil die Außenumfangsnut des Steckerteilgehäuses oder die Innenumfangsnut der Verriegelungshülse mindestens einen Positioniersteg für die Wellfeder auf, der vorzugsweise an einer Seitenflanke der Außenumfangsnut oder einer Seitenflanke der Innenumfangsnut angeordnet ist. Es ist selbstverständlich, dass nicht in beiden Nuten ein derartiger Steg vorhanden sein darf, da dieser ein Verdrehen der Verriegelungshülse auf dem Steckerteilgehäuse nicht zulassen würde. Anstelle an den Seitenflanken einer der beiden Nuten angeordnet zu sein, kann der Positioniersteg auch aus dem Grund dieser Nuten hervortreten. In an advantageous embodiment, in the connector part, the outer circumferential groove of the plug part housing or the inner circumferential groove of the locking sleeve at least one positioning web for the corrugated spring, which is preferably arranged on a side edge of the outer circumferential groove or a side edge of the inner circumferential groove. It goes without saying that such a bridge must not be present in both grooves, since this would not allow twisting of the locking sleeve on the plug part housing. Instead of being arranged on the side flanks of one of the two grooves, the positioning web can also protrude from the bottom of these grooves.
Bei einer Variante des Steckverbinderteils ist die Wellfeder gegenüber dem Steckerteilgehäuse oder der Verriegelungshülse vorzugsweise derart ausgerichtet, dass der Positioniersteg den Federspalt durchsetzt und damit die Wellfeder ver- drehsicher fixiert. Bei einer anderen Variante des Steckverbinderteils ist die Well- feder gegenüber dem Steckerteilgehäuse oder der Verriegelungshülse vorteil- hafterweise derart ausgerichtet, dass der mindestens eine Positioniersteg sich in einem Wellental der Wellfeder erstreckt. Auch auf diese Weise kann die Well- feder in Umfangsrichtung spielfrei oder spielbehaftet verdrehsicher in der Innenumfangsnut der Verriegelungshülse oder in der Außenumfangsnut des Ste- ckerteilgehäuses fixiert werden. Der Positioniersteg in dem Wellental kann zu- dem vorzugsweise einen Kompressionsbegrenzungssteg für die Wellfeder bilden, der einen axialen Kompressionsweg der Wellfeder begrenzt. Ein derartiger Kompressionsbegrenzungssteg in einem Wellental kann zusätzlich zu einem den Federspalt durchsetzenden Positioniersteg vorhanden sein. In a variant of the connector part, the corrugated spring is preferably aligned with respect to the connector part housing or the locking sleeve in such a way that the positioning web passes through the spring gap and thus fixes the wave spring in a manner secured against rotation. In another variant of the connector part, the corrugated spring is advantageously oriented relative to the connector part housing or the locking sleeve in such a way that the at least one positioning web extends in a corrugation valley of the corrugated spring. Also in this way, the corrugated spring can be secured against rotation in the circumferential direction, free of play or with play, in the inner circumferential groove of the locking sleeve or in the outer circumferential groove of the connector housing. The positioning web in the trough may also preferably form a compression limiting web for the wave spring, which limits an axial compression travel of the wave spring. Such a compression limiting web in a wave trough may be present in addition to a positioning web passing through the spring gap.
Bei einer Ausführungsform ist bei dem Steckverbinderteil die Seitenflanke der Innenumfangsnut der Verriegelungshülse oder die Seitenflanke der Außenumfangsnut des Steckerteilgehäuses wellenförmig ausgebildet ist, wobei die Kontur der Seitenflanke vorzugsweise an die Form der Wellfeder angepasst ist. Bei die- ser Variante ist die Wellenkontur natürlich in derjenigen Innenumfangsnut der Verriegelungshülse oder der Außenumfangsnut des Steckerteilgehäuses reali- siert, in der nicht der vorstehend beschriebene Positioniersteg ausgebildet ist, der die Wellfeder verdrehsicher hält. Damit wird eine Vergrößerung des axialen Federweges beim Verdrehen der Verriegelungshülse gegenüber dem Steckerteilgehäuse erreicht, sodass auch die Belastung der Wellfeder mit einer größeren Schwingungsamplitude nicht zu einem selbstständigen unerwünschten Ver- drehen der Verriegelungshülse auf dem Steckerteilgehäuse führt, und so die Verriegelung von Steckverbinderteil mit einem Gegensteckerteil besonders si- cher ist. Dies wird insbesondere dadurch begünstigt, dass die Wellenhöhe der Wellfeder größer ist als eine Breite der Außenumfangsnut des Steckerteilgehäu- ses oder der Innenumfangsnut der Verriegelungshülse, und die Wellfeder axial komprimiert in die Außenumfangsnut und/oder die Innenumfangsnut eingesetzt ist. In one embodiment, in the connector part, the side edge of the inner circumferential groove of the locking sleeve or the side edge of the outer circumferential groove of the connector part housing is formed wave-shaped, wherein the contour the side edge is preferably adapted to the shape of the wave spring. In this variant, the wave contour is, of course, realized in that inner peripheral groove of the locking sleeve or the outer circumferential groove of the plug part housing in which the positioning web described above is not formed, which holds the wave spring against rotation. Thus, an enlargement of the axial spring travel when turning the locking sleeve relative to the plug housing part is achieved, so that the load of the wave spring with a larger vibration amplitude does not lead to an independent unwanted twisting the locking sleeve on the plug housing part, and so the locking of connector part with a mating connector especially secure. This is promoted in particular by the fact that the wave height of the corrugated spring is greater than a width of the outer circumferential groove of the plug housing housing or the inner circumferential groove of the locking sleeve, and the corrugated spring is inserted axially compressed into the outer circumferential groove and / or the inner circumferential groove.
Vorzugsweise sind bei verschiedenen Ausführungsformen das mindestens eine Verriegelungsmittel der Verriegelungshülse und das mindestens eine Gegenver- riegelungsmittel des Gegenverriegelungsabschnittes als Vollgewinde, als in Umfangsrichtung segmentiertes Teilgewinde oder nach Art eines Bajonettverschlusses bzw. einer Bajonettverriegelung ausgebildet. Die Verriegelungshülse und der Gegenverriegelungsabschnitt greifen bei mit dem Gegensteckerteil zusam- mengesteckten Steckverbinderteil zumindest teilweise axial ineinander ein und sind durch Drehen der Verriegelungshülse aneinander lösbar festlegbar. Dabei kann das mindestens eine Verriegelungsmittel der Verriegelungshülse außen o- der innen an der Verriegelungshülse ausgebildet sein. Das mindestens eine dazu komplementär ausgeführte Gegenverriegelungsmittel ist entsprechend gegenseitig an dem Gegenverriegelungsabschnitt des Gegensteckerteils ausgebildet. Preferably, in various embodiments, the at least one locking means of the locking sleeve and the at least one counter locking means of the Gegenverriegelungsabschnittes are formed as full thread, circumferentially segmented partial thread or in the manner of a bayonet lock or a bayonet lock. The locking sleeve and the counter-locking section engage at least partially axially into one another in the case of the plug-in connector part mating with the mating plug part, and can be releasably fixed to one another by turning the locking sleeve. In this case, the at least one locking means of the locking sleeve outside or inside of the locking sleeve can be formed. The at least one complementarily executed counter-locking means is correspondingly mutually formed on the counter-locking portion of the mating connector part.
In einer bevorzugten Ausführungsform weist das Steckverbinderteil an der Verriegelungshülse und dem Steckerteilgehäuse Drehanschläge auf, die die Dreh- bewegung der Verriegelungshülse gegenüber dem Steckerteilgehäuse begren- zen. Diese sind natürlich nur bei Ausführungsformen der Erfindung sinnvoll, bei der das mindestens eine Verriegelungsmittel der Verriegelungshülse und das mindestens eine Gegenverriegelungsmittel des Gegenverriegelungsabschnittes nicht als Vollgewinde, sondern als in Umfangsrichtung segmentiertes Teilgewinde oder nach Art eines Bajonettverschlusses bzw. einer Bajonettverriegelung ausgebildet sind. Dabei sind die Drehanschläge der Verriegelungshülse vorzugsweise von axial verlaufenden Längswänden einer Hülseninnenausnehmung und die Drehanschläge des Steckerteilgehäuses von Längsflanken vorzugs- weise eines radial vorstehenden Gehäuseaußenzapfens gebildet. Die umfängliche Breite der Hülseninnenausnehmung ist deutlich größer als die entsprechende Breite des Gehäuseaußenzapfens. Sie sind vorzugsweise derart ge- wählt, dass eine Entriegelungsstellung und eine Verriegelungsstellung realisiert sind, zwischen die Verriegelungshülse verdreht werden kann. Die Entriegelungsstellung und die Verriegelungsstellung sind durch einen typischen Drehwinkel von etwa 30 bis 100 Winkelgraden voneinander getrennt. In der Verriegelungsstellung ist eine Längsflanke des Gehäuseaußenzapfens in Anlage an der zugeordneten Längswand der Hülseninnenausnehmung, in der Verriegelungsstel- lung die andere Längsflanke des Gehäuseaußenzapfens an der anderen Längswand der Hülseninnenausnehmung. In a preferred embodiment, the connector part has on the locking sleeve and the plug housing housing rotation stops, which rotate the Limit movement of the locking sleeve relative to the plug housing. Of course, these are only useful in embodiments of the invention, in which the at least one locking means of the locking sleeve and the at least one counter locking means of Gegenverriegelungsabschnittes are not formed as full thread, but as circumferentially segmented partial thread or like a bayonet lock or a bayonet lock. In this case, the rotational stops of the locking sleeve are preferably formed by axially extending longitudinal walls of a sleeve inner recess and the rotational stops of the plug member housing are preferably formed by longitudinal flanks of a radially projecting outer housing pin. The circumferential width of the sleeve inner recess is significantly larger than the corresponding width of the housing outer pin. They are preferably selected such that an unlocking position and a locking position are realized, between the locking sleeve can be rotated. The unlocking position and the locking position are separated by a typical angle of rotation of about 30 to 100 degrees. In the locking position is a longitudinal edge of the housing outer pin in abutment with the associated longitudinal wall of the sleeve inner recess, in the locking position, the other longitudinal edge of the housing outer pin on the other longitudinal wall of the sleeve inner recess.

Die Figur 3 zeigt das Steckverbinderteil 2 vergrößert. Dieses weist, wie der Figur 4 besser verdeutlicht, neben dem Steckerteilgehäuse 3 und der Verriegelungs- hülse 4, eine anschlussseitige Verschlusskappe 10, eine Wellfeder 11 sowie ein Federelement 12 auf. Das Federelement 12 und die Wellfeder 1 1 sind in der Figur 3 von der Verriegelungshülse 4 abgedeckt. Diese befinden sich zwischen der Verriegelungshülse 4 und dem Steckerteilgehäuse 3 im Überlappungsbe- reich. Die genaue Anordnung der Wellfeder 11 und des Federelementes 12 und deren Funktion werden nachfolgend beschrieben.

Das Federelement 12 bil- det eine zusätzliche Verdrehsicherung für die Verriegelungshülse 4. Es ist an dem Steckerteilgehäuse 3 außen unverrückbar festgelegt und wirkt mit einer in der Figur 9 sichtbaren Rastfalle 15 zusammen. Diese Verdrehsicherung ist nur in der Verriegelungsstellung der Verriegelungshülse 4 auf dem Steckerteilge- häuse 3 wirksam. Sie ermöglicht dem Anwender zudem beim Einrasten des Fe- derelements 12 in die Rastfalle 15 und beim Ausrasten des Federelementes 12 aus der Rastfalle 15 eine haptische und akustische Wahrnehmung. Das Fe- derelement 12 ist von einem vorspringend gebogenen Blattfederzuschnitt gebil- det und liegt, wie der Figur 6 entnehmbar ist, in einer Außenvertiefung 16 des Steckerteilgehäuses 3 ein. 5 shows the connector part 2 in longitudinal section illustration. In this figure, the wave spring 11 and the spring element 12 are visible. Here it can also be seen that the closure cap 10 is screwed to the plug part housing 3. The locking sleeve 4 is rotatably mounted on the plug part housing 3 and held by the acting as a loading spring wave spring 11 in the axial direction without play on the plug part housing 3. The spring element 12 forms an additional security against rotation for the locking sleeve 4. It is fixed on the plug part housing 3 on the outside immovable and cooperates with a locking catch 15 visible in FIG. This rotation is effective only in the locking position of the locking sleeve 4 on the Steckerteilge- housing 3. It also allows the user when engaging the spring element 12 in the latching latch 15 and when disengaging the spring element 12 from the latching latch 15, a haptic and acoustic perception. The Fe derelement 12 is formed by a protruding bent leaf spring blank and is located, as can be seen in FIG. 6, in an outer recess 16 of the plug part housing 3.
Die Figuren 6, 7 zeigen das Steckverbinderteil 2 mit nicht montierter Verriege- lungshülse 4 mit unterschiedlichen Blickwinkeln in perspektivischer Darstellung. Bei der Figur 6 blickt man in etwa senkrecht von oben auf Außenvertiefung 16 des Steckerteilgehäuses 3 und das darin einliegende Federelement 12, während die Blickrichtung bei der Figur 7 etwa um 120 Grad in Umfangsrichtung versetzt ist. Die Wellfeder 7, die die Verriegelungshülse 4 in axialer Richtung spielfrei auf dem Steckerteilgehäuse 3 hält, greift zum einen in eine Außenumfangsnut 17 des Steckerteilgehäuses 3 ein, und zum anderen in eine in der Figur 5 sichtbare Innenumfangsnut 18 der Verriegelungshülse 4. In dem dargestellten Ausführungsbeispiel der Erfindung ist die Wellfeder 11 in der Außenumfangsnut 17 des Steckerteilgehäuses 3 verdrehsicher und in einer Innenumfangsnut 18 der Verriegelungshülse 4 verdrehbar aufgenommen. Dazu weist die Außenumfangsnut 17 des Steckerteilgehäuses 3 einen Positioniersteg 19 auf, der die Wellfeder 11 in Umfangsrichtung gegen Verdrehen spielbehaftet sichert. Zusätzlich zu dem in der Figur 6 erkennbaren Positioniersteg 19 ist, wie der Figur 7 zu entnehmen ist, eine weiterer Positioniersteg 19, 19‘ angeordnet, der als Kompressionsbegrenzungssteg einen axialen Kompressionsweg der Wellfeder 11 begrenzt. Ein solcher Positionier-/Kompressionsbegrenzungssteg 19, 19‘ in dem Wellental 22 kann auch ohne den Positioniersteg 19, der den Federspalt 20 der Wellfeder 1 1 durchsetzt, ausgebildet sein. Figures 6, 7 show the connector part 2 with not mounted locking sleeve 4 with different angles in a perspective view. In FIG. 6, the outer recess 16 of the plug part housing 3 and the spring element 12 inserted therein are viewed approximately perpendicularly from above, while the viewing direction in FIG. 7 is offset by approximately 120 degrees in the circumferential direction. The corrugated spring 7, which holds the locking sleeve 4 in the axial direction without play on the plug housing part 3 engages on the one hand in an outer circumferential groove 17 of the plug housing part 3, and on the other in a visible in the figure 5 inner circumferential groove 18 of the locking sleeve 4. In the illustrated embodiment the invention, the corrugated spring 11 in the outer circumferential groove 17 of the plug housing part 3 against rotation and in an inner circumferential groove 18 of the locking sleeve 4 is rotatably received. For this purpose, the outer circumferential groove 17 of the plug part housing 3 has a positioning web 19, which secures the wave spring 11 in the circumferential direction against twisting. In addition to the positioning web 19 which can be seen in FIG. 6, as can be seen from FIG. 7, a further positioning web 19, 19 'is arranged, which delimits an axial compression path of the wave spring 11 as a compression limiting web. Such a positioning / compression limiting web 19, 19 'in the wave trough 22 can also be formed without the positioning web 19, which passes through the spring gap 20 of the wave spring 1 1.
In der Figur 8 ist die Wellfeder 11 nochmals allein und vergrößert dargestellt. Sie ist in Umfangsrichtung offen ausgebildet und weist einen Federspalt 20 auf. Außerdem sind durch die wellige Kontur Wellenberge 21 und Wellentäler 22 gebildet, mit denen sich die komprimierte montierte Wellfeder 11 gegen das Stecker- teilgehäuse 3 und die Verriegelungshülse 4 abstützt. Bei dem in der Figur 6 gezeigten Ausführungsbeispiel ist die Wellfeder 1 1 weitgehend verdrehsicher in der Außenumfangsnut 17 des Steckerteilgehäuses 3 aufgenommen, indem die Wellfeder 11 gegenüber dem Steckerteilgehäuse 3 derart ausgerichtet ist, dass der Positioniersteg 19 den Federspalt 20 durchsetzt. In the figure 8, the wave spring 11 is again shown alone and enlarged. It is open in the circumferential direction and has a spring gap 20. In addition, wave peaks 21 and wave troughs 22 are formed by the wavy contour with which the compressed mounted corrugated spring 11 is supported against the plug housing part 3 and the locking sleeve 4. In the embodiment shown in Figure 6, the wave spring 1 1 is largely secure against rotation in the Außenumfangsnut 17 of the plug housing part 3 is received by the corrugated spring 11 is aligned relative to the plug housing part 3 such that the positioning web 19 passes through the spring gap 20.
Bei dem in der Figur 7 abgebildeten Ausführungsbeispiel ist die Wellfeder 1 1 dadurch weitgehend verdrehsicher in der Außenumfangsnut 17 des Steckerteil- gehäuses 3 aufgenommen, dass die Wellfeder 11 gegenüber dem Steckerteil- gehäuse 3 derart ausgerichtet ist, dass der Positioniersteg 19 sich in einem Wel- lental 22 der Wellfeder 11 erstreckt. Der Positioniersteg 19 ist in beiden Fällen dabei an einer Seitenflanke 23 der Außenumfangsnut 17 des Steckerteilgehäu- ses 3 angeordnet. In the embodiment shown in FIG. 7, the corrugated spring 1 1 is thus held against rotation in the outer circumferential groove 17 of the plug-part housing 3 in such a way that the corrugated spring 11 is aligned relative to the plug-part housing 3 in such a way that the positioning web 19 settles in a welway. Lental 22 of the wave spring 11 extends. The positioning web 19 is in this case arranged on a side flank 23 of the outer circumferential groove 17 of the plug part housing 3.
Das erfindungsgemäße Steckverbinderteil 2 weist in dem dargestellten Ausfüh- rungsbeispiel eine Drehbegrenzung für die Verriegelungshülse 4 auf. Diese ist in der Figur 9 neu veranschaulicht. Dazu sind Drehanschläge 24 und 25 vorge- sehen, die die Drehbewegung der Verriegelungshülse 4 gegenüber dem Ste- ckerteilgehäuse 3 begrenzen. Die Drehanschläge 24 der Verriegelungshülse 4 sind von axial verlaufenden Längswänden 26 einer Hülseninnenausnehmung 27 und die Drehanschläge 25 des Steckerteilgehäuses 3 von Längsflanken 28 eines radial vorstehenden Gehäuseaußenzapfens 29 gebildet. The connector part 2 according to the invention has, in the illustrated embodiment, a rotation limitation for the locking sleeve 4. This is newly illustrated in FIG. For this purpose, rotational stops 24 and 25 are provided, which limit the rotational movement of the locking sleeve 4 relative to the plug-part housing 3. The rotational stops 24 of the locking sleeve 4 are formed by axially extending longitudinal walls 26 of a sleeve inner recess 27 and the rotational stops 25 of the plug part housing 3 of longitudinal edges 28 of a radially projecting housing outer pin 29.
Die Figuren 10 und 11 veranschaulichen die zwei verschiedenen Stellungen der Verriegelungshülse 4 gegenüber dem Steckerteilgehäuse 3 des Steckverbinderteils 2 mittels entsprechenden Markierung 36 auf der Oberfläche der Verriegelungshülse 4 bzw. dem Steckerteilgehäuse 3. FIGS. 10 and 11 illustrate the two different positions of the locking sleeve 4 relative to the plug part housing 3 of the connector part 2 by means of a corresponding marking 36 on the surface of the locking sleeve 4 or the plug part housing 3.
Die Figuren 12 bis 14 zeigen eine andere Ausbildung der Rastfalle 15 von Figur 9, wobei die der Innenseite der Verriegelungshülse 4 zugewandte Rastnase 30 im unverriegelten Zustand der Verriegelungshülse 4 und im verriegelten Zustand der Verriegelungshülse 4 in eine jeweils dafür vorgesehene erste Rasttasche 31 (Figur 12) oder zweite Rasttasche 32 (Figur 13) einrastet. Auf der Innenseite der Verrieglungshülse 4 zwischen der ersten Rasttasche 31 im unverriegelten Zu- stand und der zweiten Rasttasche 32 im verriegelten Zustand ist eine Führungs- kurve 33 vorgesehen, die eine Kontur aufweist, die das Federelement 12 derart unter Federspannung hält, dass die Verriegelungshülse 4 nur unter externer Krafteinwirkung auf die Verriegelungshülse 4 verdrehbar ist. Dazu die Kontur zwischen der ersten Rasttasche 31 und der zweiten Rasttasche 32 in einem ers- ten Bereich 34 flach und in einem zweiten Bereich 35 nahe der zweiten Rastta- sche 32 steil ansteigend ausgebildet ist, wobei der erste Bereich 34 länger ist als der zweite Bereich 35 und, wie aus der Figur 14 ersichtlich, vor der zweiten Rast- tasche fast nahezu komprimiert wird. Dadurch entsteht beim Einschnappen der Rastnase 30 in die zweite Rasttasche 32 ein eindeutiges Klickgeräusch. FIGS. 12 to 14 show another embodiment of the latching catch 15 of FIG. 9, wherein the latching lug 30 facing the inside of the latching sleeve 4 in the unlocked state of the latching sleeve 4 and in the locked state of the latching sleeve 4 into a respective first latching pocket 31 (FIG. 12) ) or second latching pocket 32 (Figure 13) engages. On the inside of the locking sleeve 4 between the first latching pocket 31 in the unlatched state. stand and the second latching pocket 32 in the locked state, a guide curve 33 is provided, which has a contour which holds the spring element 12 under spring tension, that the locking sleeve 4 is only rotated under external force on the locking sleeve 4. For this purpose, the contour between the first latching pocket 31 and the second latching pocket 32 is flat in a first region 34 and steeply rising in a second region 35 near the second latching pocket 32, wherein the first region 34 is longer than the second region 35 and, as can be seen from FIG. 14, almost completely compressed in front of the second latching pocket. This creates when snapping the locking lug 30 in the second latching pocket 32 a clear click sound.
