Aus der
Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der o.g. Art dahingehend zu verbessert, dass gegeneinander bewegliche Kontakte innerhalb des Steckverbinders möglich sind.The invention has for its object to provide a connector of o.g. Art improved to the effect that against each other movable contacts within the connector are possible.
Diese Aufgabe wird erfindungsgemäß durch einen Steckverbinder der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a connector of o.g. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.
Bei einem Steckverbinder der o.g. Art ist es erfindungsgemäß vorgesehen, dass mindestens ein mit dem ersten Kontaktelement elektrisch leitend verbundenes zweites Kontaktelement aus einem elektrisch leitenden Werkstoff in dem Gehäuse angeordnet ist, wobei das erste Kontaktelement einen ersten plattenförmigen Abschnitt aufweist und das zweite Kontaktelement einen zweiten plattenförmigen Abschnitt aufweist, wobei das zweite Kontaktelement ein dem kabelseitigen Ende des Steckverbinders zugewandtes Ende aufweist, welches zum elektrischen Verbindern mit dem Kabel ausgebildet ist, wobei die plattenförmigen Abschnitte der beiden Kontaktelement parallel zueinander und einander zugewandt derart angeordnet sind, dass sich die plattenförmigen Abschnitte in Richtung senkrecht zu diesen in einem Überlappungsbereich mindestens teilweise überlappen und um einen vorbestimmten Abstand voneinander entfernt sind, wobei zum elektrisch leitenden Verbinden des ersten Kontaktelementes mit dem zweiten Kontaktelement zwischen den einander zugewandten plattenförmigen Abschnitten in dem Überlappungsbereich mindestens eine Schraubenfeder aus einem elektrisch leitenden und federelastischen Werkstoff vorgesehen ist, welche das erste Kontaktelement in dem ersten plattenförmigen Abschnitt an mindestens einer ersten Kontaktfläche mit einem ersten Kontaktdruck elektrisch kontaktiert und das zweite elektrische Kontaktelement in dem zweiten plattenförmigen Abschnitt an mindestens einer zweiten Kontaktfläche mit einem zweiten Kontaktdruck elektrisch kontaktiert.In a connector of the aforementioned type, it is provided according to the invention that at least one second contact element electrically conductively connected to the first contact element is disposed of an electrically conductive material in the housing, wherein the first contact element has a first plate-shaped portion and the second contact element has a second plate-shaped Section, wherein the second contact element has a cable-side end of the connector facing the end, which is designed for electrical connection to the cable, wherein the plate-shaped portions of the two contact elements are arranged parallel to each other and facing each other such that the plate-shaped portions in the direction perpendicular to these overlap in an overlap region at least partially and are separated by a predetermined distance, wherein the electrically conductive connection of the first contact element with the second K ontaktelement between the mutually facing plate-shaped sections in the overlapping region is provided at least one coil spring made of an electrically conductive and resilient material which electrically contacts the first contact element in the first plate-shaped portion at least a first contact surface with a first contact pressure and the second electrical contact element in the second plate-shaped portion electrically contacted at least one second contact surface with a second contact pressure.
Dies hat den Vorteil, dass man das erste Kontaktelement relativ zum Gehäuse und zum zweiten Kontaktelement bewegen kann, ohne dass dabei der elektrische Kontakt zwischen den beiden Kontaktelementen negativ beeinflusst wird. Hierdurch ist die elektrische Kontaktstelle besonders zur Übertragung von hohen elektrischen Strömen, beispielsweise mit einer Stromstärke von 100 bis 400 A oder mehr, geeignet und kann durch das bewegliche erste Kontaktelement gleichzeitig mit einem Berührschutz für die elektrischen Kontakte des Steckverbinders ausgestattet werden.This has the advantage that it is possible to move the first contact element relative to the housing and to the second contact element without negatively influencing the electrical contact between the two contact elements. As a result, the electrical contact point is particularly suitable for the transmission of high electrical currents, for example, with a current of 100 to 400 A or more, and can be equipped by the movable first contact element simultaneously with a Berührschutz for the electrical contacts of the connector.
Eine besonders guten elektrische Kontakt durch einen hohen Kontaktdruck erzielt man dadurch, dass die Schraubenfeder schräggewickelte Windungen aufweist.A particularly good electrical contact is achieved by a high contact pressure, characterized in that the coil spring has obliquely wound turns.
Eine besonders hohe Anzahl von Kontaktflächen mit entsprechender Verbesserung der elektrischen Eigenschaften des Steckverbinders erzielt man dadurch, dass die Schraubenfeder ringförmig ausgebildet ist.A particularly high number of contact surfaces with a corresponding improvement in the electrical properties of the connector is achieved by the fact that the coil spring is annular.
Eine besonders gleichmäßige Verteilung das Kontaktdruckes auf die Kontaktflächen erzielt man dadurch, dass die ringförmige Schraubenfeder zwischen den beiden plattenförmigen Abschnitten in dem Überlappungsbereich derart angeordnet ist, dass mindestens ein Abschnitt einer ersten axiale Seite der ringförmigen Schraubenfeder den ersten plattenförmigen Abschnitt elektrisch und mechanisch kontaktiert sowie mindestens ein Abschnitt einer der ersten axialen Seite gegenüberliegende zweiten axialen Seite der Schraubenfeder den zweiten plattenförmigen Abschnitt elektrisch und mechanisch kontaktiert.A particularly uniform distribution of the contact pressure on the contact surfaces is achieved in that the annular coil spring between the two plate-shaped sections in the overlap region is arranged such that at least a portion of a first axial side of the annular coil spring electrically and mechanically contacts the first plate-shaped portion and at least a portion of a first axial side opposite second axial side of the coil spring electrically and mechanically contacted the second plate-shaped portion.
Eine besonders hohe Zahl von Kontaktflächen zwischen der Schraubenfeder und den plattenförmigen Abschnitten der Kontaktelemente in dem Überlappungsbereich erzielt man dadurch, dass die ringförmige Schraubenfeder innerhalb des Ringes eine Fläche im Raum begrenzt, wobei die Fläche an der Grenze zur Schraubenfeder parallel zu einer Längsachse der Schraubenfeder steht, wobei die Schraubenfeder derart angeordnet ist, dass diese Fläche mindestens teilweise zwischen den und parallel zu den plattenförmigen Abschnitten in dem Überlappungsbereich angeordnet ist.A particularly high number of contact surfaces between the coil spring and the plate-shaped sections of the contact elements in the overlapping region is achieved in that the annular coil spring within the ring defines a surface in space, the surface is parallel to a longitudinal axis of the coil spring at the boundary to the coil spring wherein the coil spring is such is arranged, that this surface is at least partially disposed between and parallel to the plate-shaped portions in the overlapping region.
Eine mechanisch besonders gute Fixierung der Schraubenfeder an dem ersten Kontaktelement erzielt man dadurch, dass die Schraubenfeder derart angeordnet ist, dass die Fläche das erste Kontaktelement teilweise umgreift.A mechanically particularly good fixation of the coil spring on the first contact element is achieved in that the helical spring is arranged such that the surface partially surrounds the first contact element.
Eine weitere Erhöhung des Kontaktdruckes mit entsprechender Verbesserung der elektrischen Eigenschaften des Steckverbinders durch ein Verkippen der Windungen der Schraubenfeder relativ zu einer Längsachse der Schraubnefeder erzielt man dadurch, dass ein Abstand zwischen den plattenförmigen Abschnitten der Kontaktelemente kleiner ausgebildet ist, als ein Außendurchmesser der Schraubenfeder.A further increase in the contact pressure with a corresponding improvement in the electrical properties of the connector by tilting the turns of the coil spring relative to a longitudinal axis of the screw spring is achieved in that a distance between the plate-shaped portions of the contact elements is smaller than an outer diameter of the coil spring.
