Description
Die Erfindung betrifft einen Steckverbinder der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a connector specified in the preamble of
Aus der
Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der gattungsgemäßen Art zu schaffen, bei dem auf einfache Weise eine gute Abdichtung sichergestellt ist.The invention has for its object to provide a connector of the generic type, in which a simple way a good seal is ensured.
Diese Aufgabe wird durch einen Steckverbinder mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a connector having the features of
Durch die Verwendung einer Profildichtung als Dichtelement kann auf einfache Weise eine Abdichtung sichergestellt werden. Beim Einsatz einer Profildichtung dient die Überwurfmutter nicht zur Sicherstellung der Dichtwirkung, sondern lediglich dazu, die Profildichtung vor Schmutz zu schützen und Steckerteil und Buchsenteil gegeneinander zu sichern. Die Dichtwirkung wird auch ohne definierte Anpresskraft erzielt. Dadurch kann die Überwurfmutter bei dem erfindungsgemäßen Steckverbinder von Hand angezogen werden.By using a profile seal as a sealing element sealing can be ensured in a simple manner. When using a profile seal, the union nut is used not to ensure the sealing effect, but merely to protect the profile seal from dirt and to secure plug part and socket part against each other. The sealing effect is achieved even without defined contact pressure. As a result, the union nut can be tightened by hand in the connector according to the invention.
Vorteilhaft weist die Profildichtung mindestens eine radiale Dichtfläche auf. Die radiale Dichtfläche wirkt bereits, wenn der Steckverbinder noch nicht vollständig angezogen ist. Dadurch kann eine gute Abdichtung sichergestellt werden. Die Profildichtung kann außerdem auftretende Toleranzen vergleichsweise gut ausgleichen. Vorteilhaft weist die Profildichtung zusätzlich oder alternativ mindestens eine axiale Dichtfläche auf. Über eine zusätzliche axiale Dichtfläche kann die Dichtwirkung auch dann sichergestellt werden, wenn die radiale Dichtfläche beispielsweise beschädigt ist.Advantageously, the profile seal has at least one radial sealing surface. The radial sealing surface is already working when the connector is not fully tightened. This ensures a good seal. The profile seal can also compensate for occurring tolerances comparatively well. Advantageously, the profile seal additionally or alternatively on at least one axial sealing surface. An additional axial sealing surface, the sealing effect can be ensured even if the radial sealing surface is damaged, for example.
Eine einfache Herstellung ergibt sich, wenn die Profildichtung an einem der Kontaktträger angespritzt ist. Die Profildichtung muss demnach nicht als separates Bauteil montiert werden und kann im Betrieb aufgrund der festen Verbindung mit dem Kontaktträger nicht verloren gehen. Es ergibt sich ein einfacher Aufbau mit wenigen Einzelteilen. Die Profildichtung ist insbesondere am Buchsenteil gehalten und liegt am Gehäuse des Steckerteils an.A simple production results when the profile seal is molded onto one of the contact carrier. Accordingly, the profile seal does not have to be mounted as a separate component and can not be lost during operation due to the fixed connection with the contact carrier. This results in a simple structure with few individual parts. The profile seal is held in particular on the socket part and is located on the housing of the plug part.
Vorteilhaft bilden die Rastmittel und Gegenrastmittel eine axiale Verrastung, die in Richtung der Längsmittelachse des Steckverbinders wirkt. Insbesondere ist zusätzlich oder alternativ vorgesehen, dass die Rastmittel und Gegenrastmittel eine radiale Verrastung bilden, die in radialer Richtung des Steckverbinders wirkt. Eine besonders vorteilhafte Gestaltung ergibt sich, wenn sowohl eine radiale als auch eine axiale Verrastung vorgesehen ist.Advantageously, the locking means and counter-locking means form an axial latching, which acts in the direction of the longitudinal center axis of the connector. In particular, additional or alternative provided that the latching means and counter-latching means form a radial latching, which acts in the radial direction of the connector. A particularly advantageous design results when both a radial and an axial latching is provided.
Dadurch, dass sowohl eine radiale als auch eine axiale Verrastung vorgesehen ist, wird erreicht, dass der Bediener bereits deutlich vor Erreichen des vollständig verschraubten Zustandes eine Verrastung spürt. Wenn der Steckverbinder weitgehend angezogen ist, kommt auch die radiale Verrastung in Eingriff. Dadurch wird die Rastempfindung verstärkt, so dass der Bediener spürt, dass der Steckverbinder weitgehend angezogen ist. Insbesondere bei Steckverbindern, die eine Dichtung umfassen, spürt der Benutzer dadurch, wann der Steckverbinder richtig angezogen und damit dicht ist.The fact that both a radial and an axial latching is provided, it is achieved that the operator feels already clearly before reaching the fully screwed state latching. When the connector is largely tightened, the radial latch also engages. This amplifies the click sensation so that the operator senses that the connector is largely tightened. In particular, with connectors that include a seal, the user senses when the connector is properly tightened and thus tight.
Vorteilhaft umfasst die axiale Verrastung mindestens eine axiale Raste, die mit Rastvertiefungen zusammenwirkt. Die Anzahl der axialen Rasten ist dabei insbesondere kleiner als die Anzahl der Rastvertiefungen. Für die radiale Verrastung sind vorteilhaft mindestens zwei Rastarme vorgesehen, wobei vorteilhaft in jeder Stellung der Rastmittel und Gegenrastmittel mindestens ein Rastarm in einem Bereich ohne radiale Rasten angeordnet ist. Dabei ist vorteilhaft in jeder Stellung der Rastmittel und Gegenrastmittel mindestens ein Rastarm in Eingriff. Durch die alternierend eingreifende Verrastung wird eine gute Entformbarkeit des Kontaktträgers bei der Herstellung in einem Spritzgussverfahren erreicht. Da die Kräfte auf mehrere Rastarme und Rasten verteilt werden, ist der Verschleiß insgesamt geringer. Die in axialer Richtung wirkenden Rastvertiefungen ergeben eine deutliche haptische Rückmeldung. Da die axiale Verrastung wirkt, wenn der Steckverbinder noch nicht vollständig angezogen ist, kann die Überwurfmutter in axialer Richtung noch ausweichen, so dass die Rastvertiefungen zu einer deutlichen haptischen Rückmeldung, aber nicht zu einem übermäßigen Erschweren des Anziehens des Steckverbinders führen. Die radiale Verrastung kommt zusätzlich zur axialen Verrastung in Eingriff.Advantageously, the axial latching comprises at least one axial catch, which cooperates with latching depressions. The number of axial detents is in particular smaller than the number of detent recesses. For the radial locking at least two latching arms are advantageously provided, wherein advantageously in each position of the latching means and counter-latching means at least one latching arm is arranged in a region without radial notches. It is advantageous in each position of the locking means and counter-locking means at least one locking arm in engagement. By alternately engaging locking a good mold release of the contact carrier is achieved in the production in an injection molding process. Since the forces are distributed over several locking arms and notches, the wear is lower overall. The acting in the axial direction locking recesses result in a clear haptic feedback. Since the axial latching acts when the connector is not fully tightened, the nut can still dodge in the axial direction, so that the locking recesses lead to a significant haptic feedback, but not to excessive complicating the tightening of the connector. The radial locking engages in addition to the axial locking.
Eine einfache Gestaltung ergibt sich, wenn die drehfest mit der Überwurfmutter vorgesehenen Rastmittel an einem Rastring ausgebildet sind, der drehfest mit der Überwurfmutter verbunden ist. Die Überwurfmutter besitzt insbesondere einen umgebogenen Rand, der den Rastring hält. Ein einfacher Aufbau wird erreicht, wenn mindestens ein Rastarm an dem Rastring angeformt ist.A simple design results when the non-rotatably provided with the nut locking means are formed on a locking ring which is rotatably connected to the nut. The cap nut has in particular a bent edge which holds the locking ring. A simple construction is achieved if at least one latching arm is formed on the latching ring.
