Abstract
Description
Die Erfindung geht aus von einem elektrischen Steckverbinder nach der Gattung des Anspruchs 1. Ein derartiger Steckverbinder ist aus der
Bei diesem Steckverbinder handelt es sich um eine Steckerleiste mit in einem Grundkörper eines Steckersgehäuses umspritzten, lagefixierten Kontaktelementen, die endseitig einerseits mit Anschlußabschnitten für ein Einfügen in Leiterplatten oder dergleichen ausgestattet sind und die andererseits mit freiliegenden Kontaktabschnstten in einen Aufnahmeraum des Steckergehäuses zur Kopplung mit Gegenkontaktelementen eines Gegensteckers ragen.In this connector is a connector strip with in a body of a plug housing overmolded, fixed-position contact elements end side on the one hand with terminal portions for insertion in printed circuit boards or the like are equipped and the other with exposed Kontaktabschnstten in a receiving space of the plug housing for coupling with mating contact elements of a Protrude mating plug.
Im Zuge der Funktionszunahme bei elektrischen Geräten, beispielsweise bei Steuergeräten im Kfz-Bereich, besteht die Notwendigkeit, bei einem vorgegebenem, begrenzten Bauraum des an dem Gerät angebrachten Steckverbinders, immer mehr Kontaktelemente einzusetzen. Dies führt dazu, dass die Abstände der Kontaktelemente zueinander verkleinert und die Kontaktelemente immer dünner ausgebildet werden, so dass deren Widerstand gegen ein Verbiegen abnimmt.In the course of functional increase in electrical equipment, such as control units in the automotive sector, there is a need to use more and more contact elements at a given, limited space of the attached to the device connector. This leads to the fact that the distances between the contact elements to each other reduced and the contact elements are always thinner, so that their resistance to bending decreases.
Erfolgt dann bei der Montage des Steckverbinders ein unbeabsichtigtes Berühren der Kontaktabschnitte der Kontaktelemente mit der Hand oder einem Werkzeug, so kann eine dadurch ausgelöste Verbiegung einzelner Kontaktabschnitte eine Kopplung mit den Gegenkontaktelementen des Gegensteckers verunmöglichen, insbesondere dann, wenn die Kopplung maschinell erfolgt. Ein solchermaßen veränderter Steckverbinder ist somit nicht mehr einsetzbar.If an unintentional contact between the contact elements of the contact elements by hand or a tool then occurs during assembly of the connector, a bending of individual contact sections caused thereby can make coupling with the mating contact elements of the mating connector impossible. especially when the coupling is done by machine. Such a modified connector is therefore no longer applicable.
Der erfindungsgemäße elektrische Steckverbinder mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass die zuvor erwähnten Unzulänglichkeiten in zufriedenstellender Weise vermieden werden.The electrical connector according to the invention with the characterizing features of claim 1 has the advantage that the aforementioned shortcomings are avoided in a satisfactory manner.
Dazu werden Kontaktabschnitte des Steckverbinders, die zur Kopplung mit Gegenkontaktelementen eines Gegensteckverbinders vorgesehen sind, durch wenigstens ein Abstützelement gegen eine radiale Verlagerung stabilisiert. Damit ist es möglich, auch Kontaktabschnitte mit geringer Querschnittsfläche bauraumsparend einzusetzen und trotzdem eine sichere Kontaktierung zu verwirklichen.For this purpose, contact portions of the connector, which are provided for coupling with mating contact elements of a mating connector, stabilized by at least one support element against a radial displacement. This makes it possible to use contact sections with a small cross-sectional area space saving and still achieve a secure contact.
In den Rahmen der Erfindung fallen auch sämtliche Kombinationen aus zumindest zwei von in der Beschreibung, den Ansprüchen und/oder den Figuren offenbarten Merkmalen.All combinations of at least two features disclosed in the description, the claims and / or the figures also fall within the scope of the invention.
In den Unteransprüchen sind vorteilhafte Maßnahmen für die Realisierung der Erfindung angegeben.In the dependent claims advantageous measures for the realization of the invention are given.
Durch die Verwendung wenigstens eines Abstützelements, das über eine Teillänge der Kontaktabschnitte an diesen anliegt oder mit ihnen verbunden ist, lässt sich die Abstützung der Kontaktelemente mit geringem baulichen Aufwand durchführen.By using at least one support element, which is applied over a partial length of the contact portions of these or connected to them, the support of the contact elements can be carried out with little structural complexity.
Mit wenigstens einem Abstützelement, das über die Gesamtlänge der Kontaktabschnitte an diesen anliegt oder mit ihnen verbunden ist, lässt sich eine vollständige Abstützung der Kontaktelemente in Richtung zum Abstützelement erreichen.With at least one support element, which is applied over the entire length of the contact portions of these or connected to them, a complete support of the contact elements can be achieved in the direction of the support element.
Durch wenigstens ein Abstützelement, das über die Gesamtlänge der Kontaktabschnitte an diesen anliegt oder mit ihnen verbunden ist und das darüber hinaus die Kontaktabschnitte axial überragt lassen sich die Fügungskräfte mit den Gegenkontaktelementen des Gegensteckverbinders reduzieren, da die Spitzengeometrie des Abstützelements exakter geformt werden kann als bei gestanzten Spitzen der Kontaktabschnitte und auch der Reibkoeffizient für die Gegenkontaktelemente herabgesetzt werden kann.By at least one support element, which is applied over the entire length of the contact portions of these or connected to them and beyond the contact portions axially beyond the mating forces with the mating contact elements of the mating connector reduce because the tip geometry of the support element can be formed more accurate than punched Tips of the contact portions and also the coefficient of friction for the mating contact elements can be reduced.
Mit der Verbindung des wenigstens einen Abstützelements mit den Kontaktabschnitten über einen Kunststoffspritzvorgang wird eine Haftung des Abstützelements mit den Kontaktabschnitten erreicht, wodurch die Kontaktabschnitte auch noch in Richtungen gestützt werden, die nicht durch den Formschluß mit dem Abstützelement abgedeckt sind.With the connection of the at least one support element with the contact portions via a plastic injection process adhesion of the support element is achieved with the contact portions, whereby the contact portions are also supported in directions that are not covered by the positive engagement with the support element.
Durch die Ausbildung des wenigstens einen Abstützelements als eine Wand, die die in Reihe angeordneten Kontaktabschnitte aufnimmt, lässt sich in fertigungstechnisch einfacher Weise das Abstützelement darstellen. Bei einer Wand, die dünner als die Kontaktabschnitte ist, werden geringe Materialkosten für das Abstützelement realisiert. Bei einer Wand, die gleichdick wie die Kontaktabschnitte ist, ergibt sich eine einfache Werkzeugausgestaltung für den Kunststoffspritzvorgang. Bei einer Wand, die dicker wie die Kontaktabschnite ist, ergeben sich Führungsflächen für den Fügevorgang des Gegensteckverbinders auf dem Steckverbinder.Due to the design of the at least one support element as a wall, which receives the contact sections arranged in series, the support element can be represented in a production-technically simple manner. With a wall that is thinner than the contact portions, low material costs are realized for the support element. For a wall that is the same thickness as the contact sections, there is a simple tool design for the plastic injection process. For a wall that is thicker than the Kontaktabschnite, resulting guide surfaces for the joining process of the mating connector on the connector.
Mit der Anbringung von Versteifungsrippen an der Wand lässt sich auch das Abstützelement selbst stabilisieren.With the attachment of stiffening ribs on the wall can also stabilize the support itself.
