Des weiteren ist ein einziges oder es sind mehrere Ferritelemente vorgesehen, die jeweils zwei Durchgangslöcher aufweisen, in denen die Kontaktbuchsenabschnitte mit ihren Außenflächen aufgenommen sind. Der Steckverbinder umfasst ferner ein Gehäuse aus einem elektrisch isolierenden Material, welches einen Einsteckabschnitt zum Einführen in die Einsteckkammer des Gegensteckverbinders besitzt und der eine Aufnahmekammer für das bzw. die Ferritelemente bildet. Es sind ferner Durchtrittsöffnungen für das Eintreten der Kontaktstifte vorhanden. Das Gehäuse weist ferner einen durch einen Deckel verschließbaren offenen Gehäuseabschnitt auf, in dem die Kontaktelemente gehalten sind. Ferner sind Öffnungen vorgesehen, durch welche die beiden Kabel in den offenen Abschnitt des Gehäuses eingeführt werden. Dabei bilden die Öffnungen und die zugehörigen Ergänzungsflächen am Deckel zwischen dem Kabel und dem Gehäuse bzw.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder vorzusehen, bei dem die Kontaktelemente, auch bei Einwirken von Zugkräften über die angeschlossenen Kabel, so sicher gehalten werden, dass die Kontaktbuchsenabschnitte davon unbeeinflusst bleiben und dass zusätzlich dann, wenn den Kontaktbuchsenabschnitten Ferritelemente zugeordnet sind, ein leichtes Verbinden der im Gehäuse des Steckverbinders aufgenommenen Kontaktbuchsenabschnitte mit den Kontaktstiften des Gegensteckverbinders auch bei nicht genauer Zentrierung der Bauteile möglich ist, wobei die Ferritelemente ebenfalls nicht durch einwirkende Zugkräfte belastet werden.The invention has for its object to provide a connector in which the contact elements, even when exposed to tensile forces on the connected cables are kept so secure that the contact socket sections remain unaffected and that in addition, if the contact socket sections ferrite elements are assigned, a easy connection of the recorded in the housing of the connector contact socket sections with the contact pins of the mating connector is also possible in non-precise centering of the components, wherein the ferrite elements are also not burdened by acting tensile forces.
Gelöst wird diese Aufgabe erfindungsgemäß durch einen Steckverbinder nach Anspruch 1. Bevorzugte Ausführungsbeispiele ergeben sich aus den Unteransprüchen.This object is achieved according to the invention by a connector according to
Da der Verlängerungsabschnitt über dritte Haltemittel am offenen Gehäuseabschnitt festgelegt ist, wird erreicht, dass das Kontaktelement vor und hinter dem Anschlussabschnitt festgehalten ist, so dass beim Verbinden des Anschlussabschnittes mit dem Leiter des zugehörigen Kabels die Kräfte günstig abgefangen werden und darüber hinaus auch in diesem Bereich eine sichere Halterung gegeben ist, weil über das Kabel auf die Kontaktelemente einwirkende Zugkräfte sicher und nahe zu dem Bereich abgefangen werden, wo das Kabel mit dem zugehörigen Kontaktelement verbunden ist. Der Kontaktbuchsenabschnitt bleibt unberührt.Since the extension portion is fixed on the open housing portion via third holding means, it is achieved that the contact element is held in front of and behind the connection portion, so that when connecting the connection portion with the head of the associated cable, the forces are intercepted low and beyond this, a secure support is given in this area, because on the cable acting on the contact elements tensile forces are safely intercepted and close to the area where the cable is connected to the associated contact element , The contact socket section remains untouched.
Von Vorteil bei Steckverbindern mit Ferritelementen ist, dass die Kontaktbuchsenabschnitte der beiden Kontaktelemente gegenüber den Durchgangslöchern beim Verbinden eine Relativbewegung ausführen können, so dass das Verbinden des Steckverbinders mit dem Gegensteckverbinder erleichtert wird und darüber hinaus keine Beschädigungen eintreten können. Es erfolgt bei dem Zusammenstecken der beiden Steckverbinder eine Selbstausrichtung der Kontaktbuchsen gegenüber den Kontaktstiften des Gegensteckverbinders. Die Halterung der Kontaktelemente erfolgt im Bereich des Verbindungsabschnittes am offenen Gehäuseabschnitt. Der Deckel sichert im übrigen im verschlossenen Zustand die Kontaktelemente und darüber hinaus auch durch zweite Haltemittel, die am Deckel und offenen Gehäuseabschnitt vorgesehen sind, den/die mit den Kontaktelementen verbundenen Kabel. Es können mehr als zwei Kontaktelemente vorgesehen werden, wenn dies erforderlich ist. Das Ferritelement kann dann eine entsprechende Anzahl von Durchgangslöchern aufweisen.An advantage of connectors with ferrite elements is that the contact socket portions of the two contact elements relative to the through holes during connection can perform a relative movement, so that the connection of the connector is facilitated with the mating connector and moreover can not cause damage. It takes place in the mating of the two connectors self-alignment of the contact sockets against the contact pins of the mating connector.

The lid secures the rest in the closed state, the contact elements and beyond also by second holding means, which are provided on the lid and open housing portion, the / connected to the contact elements cable. There may be more than two contact elements, if necessary. The ferrite element may then have a corresponding number of through holes.
Zur Vergrößerung der Haltekraft ist ferner vorgesehen, dass der Verlängerungsabschnitt mindestens einen Sicherungsabschnitt aufweist, der in eine ihm zugehörige Sicherungsausnehmung des offenen Gehäuseabschnitts eingreift. Die Zugkräfte, die auf das Kontaktelement ausgeübt werden, werden dadurch bereits nahe zum Eintrittsende des Kabels in das Gehäuse abgefangen, so dass der Bereich des Kontaktelementes, der sich in Richtung zum Kontaktbuchsenabschnitt befindet, im wesentlichen von Auszugskräften frei gehalten ist.To increase the holding force is further provided that the extension portion has at least one securing portion which engages in an associated securing recess of the open housing portion. The tensile forces exerted on the contact element are thereby already intercepted close to the entry end of the cable into the housing, so that the area of the contact element which is in the direction of the contact socket section is essentially kept free of pull-out forces.
Ergänzend ist hierzu vorgesehen, dass der Sicherungsabschnitt rechtwinklig zum Verlauf des Verlängerungsabschnitts, des Verbindungsabschnitts und des Anschlussabschnitts abgebogen ist. Alternativ ist vorgeschlagen, dass der Verlängerungsabschnitt mindestens einen Sicherungsabschnitt aufweist, der durch eine aus dem Verlängerungsabschnitt ausgestanzte und zu dessen Verlauf abgekröpfte Zunge gebildet ist, die im montierten Zustand in eine unterhalb des Verlängerungsabschnitts im offenen Gehäuseabschnitt liegende Sicherungsausnehmung eingreift, welche die dritten Haltemittel (124) bildet.In addition, it is provided for this purpose that the securing portion is bent at right angles to the course of the extension portion, the connecting portion and the connecting portion. Alternatively, it is proposed that the extension section has at least one securing portion which extends through one the tongue is punched out of the extension portion and bent to its course, which engages in the mounted state in a below the extension portion in the open housing portion securing recess, which forms the third holding means (124).
Günstig ist auch eine Ausgestaltung, bei der die ersten Haltemittel und/oder die dritten Haltemittel als Halteausnehmungen im offenen Gehäuseabschnitt vorgesehen sind. Der Verbindungsabschnitt bzw. der Verlängerungsabschnitt werden in diese Halteausnehmungen eingedrückt. Dabei kann die Halterung dadurch verstärkt werden, dass der Verbindungsabschnitt und/oder der Verlängerungsabschnitt mit ihren Seitenkanten oder daran angebrachten Krallen in jeweils eine von zwei gegenüberliegenden Wandabschnitten, welche die Halteausnehmung begrenzen, zur Festlegung eingreifen.Also favorable is an embodiment in which the first holding means and / or the third holding means are provided as holding recesses in the open housing section. The connecting portion and the extension portion are pressed into these retaining recesses. In this case, the holder can be reinforced in that the connecting portion and / or the extension portion engage with its side edges or claws attached thereto in each one of two opposite wall portions which define the retaining recess, for fixing.
Es ist jedoch auch vorgesehen, dass der Verlängerungsabschnitt in als Nuten gestalteten dritten Haltemittel des offenen Gehäuseabschnitts gehalten sein kann. Schließlich kann die Halterung gegen Zugkräfte auch noch dadurch verbessert werden, dass vom Verbindungsabschnitt seitlich Flügel abstehen, die gegen die Wand der den Verbindungsabschnitt aufnehmenden Halteausnehmung zur Anlage kommen.However, it is also contemplated that the extension portion may be held in grooves formed third holding means of the open housing portion. Finally, the holder can also be improved against tensile forces by the fact that project from the connecting portion laterally wings, which come against the wall of the connecting portion receiving retaining recess to the plant.
Für die Montage ist es günstig, wenn die Aufnahmekammer zur Aufnahme des Ferritelementes zum Einführen des Ferritelementes von dem offenen Gehäuseabschnitt aus zugänglich ist.For mounting, it is favorable if the receiving chamber for receiving the ferrite element for inserting the ferrite element is accessible from the open housing section.
Zur Sicherung der beiden Kontaktelemente, die im Bereich des Durchbruches liegen, ist vorgesehen, dass der Deckel drei Distanzvorsprünge aufweist, die in den Durchbruch eingreifen, von denen einer zwischen die Anschlussabschnitte der beiden Kontaktelemente und die beiden anderen jeweils zwischen einen Anschlussabschnitt und einer der seitlichen Wände des Durchbruchs angeordnet sind.To secure the two contact elements, which are in the region of the opening, it is provided that the lid has three spacer projections which engage in the opening, one of which between the terminal portions of the two contact elements and the other two between each terminal portion and one of the lateral Walls of the breakthrough are arranged.
Der Deckel ist vorzugsweise selbst durch Sicherungsvorsprünge und Sicherungsarme am Gehäuse festgelegt. Günstig ist, wenn bei der Herstellung der Deckel einstückig mit dem Gehäuse ausgeführt ist. Zur Festlegung des Steckverbinders am Gegensteckverbinder ist vorgesehen, dass dem Einsteckabschnitt des Gehäuses federnde Laschen mit jeweils einem Haltevorsprung angeformt sind. Diese Haltevorsprünge greifen in eine entsprechend angeordnete Nut in der Einsteckkammer des Gegensteckverbinders ein.The lid is preferably itself fixed by securing projections and securing arms on the housing. It is favorable if in the manufacture of the cover in one piece is executed with the housing. To fix the connector on the mating connector is provided that the insertion portion of the housing resilient tabs are each formed with a retaining projection. These retaining projections engage in a correspondingly arranged groove in the insertion of the mating connector.
Der Deckel kann dazu genutzt werden, die Bauteile insgesamt in dem Gehäuse zu sichern. Beispielsweise wird der Deckel genutzt, um das Ferritelement in der Aufnahmekammer zu halten.The lid can be used to secure the components as a whole in the housing. For example, the lid is used to hold the ferrite element in the receiving chamber.
Es sind verschiedene Ausführungsformen hinsichtlich der Ausbildung des Gehäuses denkbar. Bei einer ersten Ausführungsform sind der Einsteckabschnitt des Gehäuses und der offene Gehäuseabschnitt entlang der Verbindungsachse hintereinander angeordnet. Es ist jedoch auch eine Anordnung möglich, bei der der Einsteckabschnitt des Gehäuses zum offenen Gehäuseabschnitt abgewinkelt ist. Entsprechend sind der Verbindungsabschnitt, der Anschlussabschnitt und der Verlängerungsabschnitt der Kontaktelemente entsprechend zum Kontaktbuchsenabschnitt abgewinkelt.There are various embodiments in terms of the design of the housing conceivable. In a first embodiment, the insertion portion of the housing and the open housing portion along the connection axis are arranged one behind the other. However, it is also an arrangement possible in which the insertion portion of the housing is angled to the open housing portion. Accordingly, the connecting portion, the connecting portion and the extension portion of the contact elements are angled in accordance with the contact socket portion.

Der Kontaktbuchsenabschnitt 29 verläuft im eingebauten Zustand des Kontaktelementes 28 parallel zur Verbindungsachse X. Ausgehend von einer Wand des Kontaktbuchsenabschnitts 29 verläuft parallel zur Verbindungsachse X ein streifenförmiger Verbindungsabschnitt 30, der im Abstand zum Kontaktbuchsenabschnitt 28 rechtwinklig abgewinkelt ist. Dieser Verbindungsabschnitt 30 weist einen Abschnitt mit seitlich abstehenden Flügeln 45 zum Halten des Kontaktelementes 28 parallel zur Querachse Y des offenen Gehäuseabschnitts 10 gegen durch das zugehörige Kabel 6 einwirkende Zugkräfte auf, wobei sich die Flügel 45 gegen die erste Wand 18 in Richtung vom Kontaktbuchsenabschnitt 29 weg abstützen können. Ferner dienen die Seitenkanten 31 zum Eingreifen in die Wand der die erste Haltemittel 22 bildenden Halteausnehmung 24 in der ersten Wand 18. Daran folgt anschließend ein Anschlussabschnitt 32, der zwei Crimplaschen 33 umfasst, die zur Vercrimpung mit dem Leiter 7 eines Kabels 6 dienen und die, wie u.a. aus
Das dem Verbindungsabschnitt 30 abgewandte Ende des Kontaktbuchsenabschnitts 29 bildet eine Öffnung, die im montierten Zustand einer Durchtrittsöffnung 13 gegenüberliegt und den Eintritt eines Kontaktstiftes 4 in die Kontaktammer 29a erlaubt.The end facing away from the connecting
An den Anschlussabschnitt 32 schließt sich vom Kontaktbuchsenabschnitt 29 weg ein Verlängerungsabschnitt 34 an, der ebenfalls etwa parallel zur Querachse Y verläuft. An diesen schließt sich wiederum abgewinkelt ein streifenförmiger Sicherungsabschnitt 35 an, der sich parallel zum Einsteckabschnitt 9 erstreckt und dessen Seitenkanten mit sägezahnartigen Zähnen versehen sind. Dieser wird in die zugehörige Sicherungsausnehmung 25 im offenen Gehäuseabschnitt 10 nahe zu den zweiten Haltemitteln 23 eingepresst, so dass seine Zähne in das die Sicherungsausnehmung 25 begrenzende Material des offenen Gehäuseabschnitts 10 eingreifen (sh.
