Leistungs-Steckkontakt sowie LeiterplattenanordnungPower plug contact as well as PCB arrangement
Stand der TechnikState of the art
Die Erfindung betrifft einen elektrischen Leistungs- Steckkontakt gemäß dem Oberbegriff des Anspruchs 1 sowie eine Leiterplattenanordnung gemäß Anspruch 11.The invention relates to an electrical power plug contact according to the preamble of claim 1 and a printed circuit board assembly according to claim 11.
Heute werden im Automobilbereich zur Kontaktierung von Leiterplatten von Steuergeräten und anderen Komponenten, wie Ventilen, Sensoren, Aktoren, etc. lösbare Steckverbindungen zur elektrischen Kontaktierung genutzt, die über eine sogenannte Messerleiste, auch Stiftwanne genannt, die Schnittstelle realisieren. Eine derartige Steckverbindung mit Messerleiste ist in der GB 2257579 A beschrieben. Üblicherweise bestehen die Messerleisten aus einem metallischen, mit Kunststoff umspritzten Stanzgitter, welches die sogenannten Pins für die Schnittstelle zum Steckverbinder realisiert. Das Stanzgitter wird durch Löten, Schweißen, etc. oder über sogenannte Press-fit-Verbindungen an einer Leiterplatte festgelegt und dient zur Aufnahme eines Steckkontaktes.Today in the automotive industry for contacting printed circuit boards of control devices and other components, such as valves, sensors, actuators, etc. releasable plug-in connections are used for electrical contacting, called the so-called male connector, also called pin tray, the interface. Such a connector with male connector is described in GB 2257579 A. Usually, the male connectors consist of a metallic stamped grid encased with plastic, which implements the so-called pins for the interface to the connector. The stamped grid is fixed by soldering, welding, etc. or via so-called press-fit connections on a printed circuit board and serves to receive a plug-in contact.
Nachteilig bei den bekannten Steckverbindungen mit Messerleiste ist der hohe Bauraumbedarf. Eine Miniaturisierung scheiterte bislang an den zu realisierenden Normalkräften des Steckkontaktes zur sicheren elektrischen Kontaktierung des Steuergerätes sowie an der zu garantierenden Robustheit des Steckkontaktes. Weitere im Automobilbereich zum Einsatz kommende Steckverbindungen sind in der DE 202 08 635 Ul, der EP 0 971 446 Bl, der DE 102 24 889 Al, der DE 102 24 683 Al, der DE 44 39 105 Cl sowie der DE 101 21 654 Al beschrieben.A disadvantage of the known connectors with male connector is the high space requirement. A miniaturization failed so far to be realized in the normal forces of the plug contact for secure electrical contacting of the control unit and to be guaranteed robustness of the plug contact. Further connectors used in the automotive sector are described in DE 202 08 635 U1, EP 0 971 446 B1, DE 102 24 889 A1, DE 102 24 683 A1, DE 44 39 105 C1 and DE 101 21 654 A1 described.
Aus der DE 199 34 302 Al ist es bekannt, zwei Leiterplatten elektrisch mit einem Steckkontakt miteinander zu verbinden. Der bekannte Steckverbinder ist nicht zur elektrischen An- bindung einer Leiterplatte an ein elektrisches Kabel eines Kabelbaums geeignet. Nachteilig ist der mehrteilige Aufbau des Steckverbinders.From DE 199 34 302 Al it is known to connect two printed circuit boards electrically with a plug contact with each other. The known connector is not suitable for the electrical connection of a printed circuit board to an electrical cable of a cable harness. A disadvantage is the multi-part construction of the connector.
In der EP 110 73 73 A2 ist eine konstruktiv aufwändige Press-Fit-Steckverbindung beschrieben.In EP 110 73 73 A2 a structurally complex press-fit connector is described.
Offenbarung der Erfindung Technische AufgabeDISCLOSURE OF THE INVENTION Technical Problem
Der Erfindung liegt die Aufgabe zugrunde, einen einfach aufgebauten, robusten und zum Übertragen hoher Ströme geeigneten Leistungs-Steckkontakt vorzuschlagen, der zum Anbinden eines elektrischen Kabels eines Kabelbaums in einem Kraftfahrzeug an ein Steuergerät oder eine andere Kraft- fahrzeugkomponente geeignet ist. Bevorzugt soll der elektrische Leistungs-Steckkontakt einen geringen Bauraumbedarf haben. Ferner besteht die Aufgabe darin, eine Leiterplattenanordnung vorzuschlagen, bei der eine Leiterbahn mit einem einfach aufgebauten, robusten und zur Übertragung grö- ßer Ströme geeigneten Leistungs-Steckkontakt kontaktiert ist. Auf das Vorsehen von Messerleisten auf der Leiterbahn zur Kontaktierung des Steckkontaktes soll bevorzugt verzichtet werden können. Technische LösungThe invention has for its object to provide a simple design, robust and suitable for transmitting high currents power connector, which is suitable for connecting an electrical cable of a wiring harness in a motor vehicle to a control unit or other motor vehicle component. Preferably, the electrical power plug contact should have a low space requirement. Furthermore, the object is to propose a printed circuit board arrangement in which a conductor track is contacted with a simply constructed, robust power transmission plug-in contact suitable for the transmission of large currents. On the provision of male connectors on the conductor for contacting the plug contact should preferably be dispensed with. Technical solution
Diese Aufgabe wird hinsichtlich des Leistungs- Steckkontaktes mit den Merkmalen des Anspruchs 1 und hinsichtlich der Leiterplattenanordnung mit den Merkmalen des Anspruchs 11 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumin- dest zwei von in der Beschreibung, den Ansprüchen und/oder den Figuren offenbarten Merkmalen.This object is achieved with regard to the power plug-in contact with the features of claim 1 and with regard to the printed circuit board assembly having the features of claim 11. Advantageous developments of the invention are specified in the subclaims. All combinations of at least two features disclosed in the description, the claims and / or the figures fall within the scope of the invention.
Der Erfindung liegt der Gedanke zugrunde, den Kontaktbereich des Leistungs-Steckkontaktes derart auszubilden, dass er zur unmittelbaren Kontaktierung einer Leiterbahn einer Leiterplatte geeignet ist. Dadurch kann auf das Vorsehen von Messerleisten, wie sie im Stand der Technik notwendig sind, verzichtet werden. Durch den Verzicht auf Messerleisten wird bei Einsatz eines nach dem Konzept der Erfindung ausgebildeten Leistungs-Steckkontaktes der Bauraumbedarf für die gesamte Steckverbindung erheblich reduziert. Zum Erzeugen einer Anpresskraft umfasst der Leistungs- Steckkontakt Federmittel. Bei der Auslegung der Federmittel zum Erzeugen der normal zur Einsteckrichtung gerichteten Anpresskraft des Steckkontaktes auf die Leiterbahn der Leiterplatte ist darauf zu achten, dass die zu erzielende Normalkraft (Anpresskraft) ausreichend groß ist, um eine dauerhafte Kontaktierung und einen Toleranzausgleich bei Unebenheiten oder Maßschwankungen zu ermöglichen. Bevorzugt beträgt die Normalkraft etwa 0,5 bis 4N oder mehr. Besonders bevorzugt ist eine Ausführungsform, bei der die Federmittel einen großen elastischen Federweg von bis etwa 0,4mm realisieren. Weiter bevorzugt ist es, wenn sich der Leistungs-Steckkontakt auf einer der Leiterbahn der Leiterplatte gegenüberliegenden Kunststofffläche abstützt. Bevorzugt ist der Leistungs-Steckkontakt derart dimensioniert, dass die elektrische Stromtragfähigkeit bei einer Standard- leiterplatte mindestens 1,5A Dauerstrom bei Temperaturen bis 800C und/oder zumindest kurzzeitig mindestens 8A bei Temperaturen bis mindestens 800C beträgt.The invention is based on the idea to form the contact region of the power plug contact such that it is suitable for direct contacting of a conductor track of a printed circuit board. This can be dispensed with the provision of male connectors, as they are necessary in the prior art. By dispensing with male connectors the space requirement for the entire connector is significantly reduced when using a trained according to the concept of the invention power connector. To generate a contact pressure, the power plug contact comprises spring means. When designing the spring means for generating the normally applied to the insertion direction pressing force of the plug contact on the conductor of the circuit board is important to ensure that the normal force to be achieved (contact force) is sufficiently large to allow permanent contact and tolerance compensation for unevenness or dimensional variations , Preferably, the normal force is about 0.5 to 4N or more. Particularly preferred is an embodiment in which the spring means realize a large elastic travel of up to about 0.4mm. It is further preferred if the Power plug contact on one of the conductor track of the printed circuit board opposite plastic surface supported. Preferably, the power plug contact is dimensioned such that the electrical current carrying capacity of a standard printed circuit board is at least 1.5A continuous current at temperatures up to 80 0 C and / or at least briefly at least 8A at temperatures up to at least 80 0 C.
Zur Realisierung eines besonders robusten und einfach auf- gebauten Steckkontaktes ist es vorteilhaft, diesen als vollständig aus Metall ausgebildetes Stanz-Biegeteil auszubilden. Bevorzugt beträgt dabei die Blechdicke des gestanzten Blechs weniger als 0,3mm, ganz besonders bevorzugt etwa 0,2mm. Besonders zweckmäßig ist es, wenn der Steckkontakt dabei einteilig ausgebildet ist, wodurch auf eine Montage von aneinander festzulegenden Steckkontaktbauteilen verzichtet werden kann. Dabei kann das Stanz-Biegeteil beispielsweise aus einer Kupferlegierung, oder aus Stahl, insbesondere rostfreiem Federstahl oder Edelstahl ausgebildet werden.To realize a particularly robust and simply constructed plug contact, it is advantageous to form this formed as a completely made of metal stamped and bent part. Preferably, the sheet thickness of the stamped sheet is less than 0.3mm, most preferably about 0.2mm. It is particularly expedient if the plug contact is formed in one piece, which can be dispensed with an assembly of mutually fixed plug contact components. In this case, the stamped and bent part can be formed for example of a copper alloy, or of steel, in particular stainless spring steel or stainless steel.
Bei einer alternativen Ausführungsform ist der Steckkontakt zweiteilig ausgebildet, wobei die beiden den Steckkontakt bildenden Bauteile bevorzugt aus Metall, ganz bevorzugt aus unterschiedlichen Metallen bzw. Metalllegierungen ausgebildet sind. Es ist eine Ausführungsform realisierbar, bei der beide Bauteile aus derselben oder unterschiedlichen Kupferlegierung ausgebildet sind. Ganz besonders bevorzugt ist eine Materialpaarung aus einer Kupferlegierung und einer Stahllegierung, insbesondere nicht rostender Federstahl oder Edelstahl.

In den Figuren sind gleiche Elemente und Elemente mit der gleichen Funktion mit den gleichen Bezugszeichen gekennzeichnet .In the figures, like elements and elements having the same function are denoted by the same reference numerals.
In den Fig. 1 bis 3 ist ein Leistungs-Steckkontakt 1 zur unmittelbaren Kontaktierung einer in Fig. 3 gezeigten Leiterbahn 2 auf einer Leiterplatte 3 gezeigt. Konkret dient der in den Fig. 1 bis 3 dargestellte Leistungs-Steckkontakt 1 zur elektrischen Kontaktierung eines Tür-Steuergerätes in einem Kraftfahrzeug bzw. zur Anbindung eines Kabelbaums an dieses Steuergerät. Zu erkennen ist, dass der Leistungs- Steckkontakt 1 durch Vercrimpen an einem abisolierten Ende 4 eines elektrischen Kabels 5 festgelegt ist. Hierzu weist der Leistungs-Steckkontakt 1 als Krimplaschen ausgebildete Verbindungsmittel 6 auf, die auf ihrer Innenseite nicht mit einem Bezugszeichen versehene Leiterkontaktflächen- kontaktierung des elektrischen Kabels 5 bilden.FIGS. 1 to 3 show a power plug contact 1 for the direct contacting of a printed conductor 2 shown in FIG. 3 on a printed circuit board 3. Specifically, the power plug contact 1 shown in FIGS. 1 to 3 is used for making electrical contact with a door control unit in a motor vehicle or for connecting a wiring harness to this control unit. It can be seen that the power plug-in contact 1 is fixed by crimping on a stripped end 4 of an electric cable 5. For this purpose, the power plug-in contact 1 designed as Krimplaschen connecting means 6 which form on its inside not provided with a reference Leiterkontontflächen- contact of the electric cable 5.
Bei dem dargestellten Leistungs-Steckkontakt 1 handelt es sich um ein einteiliges, vollständig aus Metall ausgebildetes, Stanzbiegeteil. Dieses umfasst auf seiner Unterseite 7 einen Kontaktbereich 8 zur unmittelbaren Anlage auf der Leiterbahn 2 der Leiterplatte 3. Der Kontaktbereich 8 ist an Federmitteln 9 ausgebildet, mit denen eine Anpresskraft (Normalkraft) senkrecht zur Einsteckrichtung 10 auf den Kontaktbereich 8 ausübbar ist. Der Kontaktbereich 8 ist gebildet von vier, in Richtung der Leiterbahn 2 erhabenen, balligen Anlageabschnitten 11 zur Realisierung einer redundanten Kontaktierung.In the illustrated power connector 1 is a one-piece, formed entirely of metal, stamped and bent part. This comprises on its underside 7 a contact area 8 for direct contact with the conductor 2 of the printed circuit board 3. The contact area 8 is formed on spring means 9, with which a contact force (normal force) perpendicular to the insertion direction 10 on the contact area 8 can be exercised. The contact region 8 is formed by four, in the direction of the conductor 2 raised, convex abutment portions 11 for the realization of a redundant contact.
Wie sich insbesondere aus Fig. 3 ergibt, ist der mehrteilige Kontaktbereich 8 ausgebildet an einem gebogenen Strei- fenabschnitt 12 des Leistungs-Steckkontaktes 1, der gleichzeitig mit seinem unteren, der Leiterbahn 2 zugewandten Bereich, die Federmittel 9 bildet. Wie aus Fig. 3 zu entnehmen ist, ist der Streifenabschnitt 12 im Bereich der Federmittel 9 bzw. im Kontaktbereich 8 längsgeschlitzt ausge- führt, also von zwei relativ zueinander verstellbaren Federmitteln 9 gebildet und liegt im Bereich seines unteren, in der Zeichnungsebene rechten, freien Endes 13 an einem in einen als Flachabschnitt ausgebildeten stromführenden Bereich 14 an, wobei sich der stromführende Bereich 14 in Einsteckrichtung 10 betrachtet zwischen den Verbindungsmitteln 6 und dem Kontaktbereich 8 befindet. Für den Fall, dass der Leistungs-Steckkontakt 1 nicht eingesteckt ist und somit die Federmittel 9 nicht kraftbeaufschlagt sind, und somit keine Anpresskraft als Gegenkraft erzeugen, ist das freie Ende 13 der Federmittel 9 von dem stromführenden Bereich 14 beabstandet. Durch Einstecken des Leistungs- Steckkontaktes 1 und der damit einhergehenden Kraftbeaufschlagung, schwenken die Federmittel 9 mit ihrem freien Ende 13 (von unten) gegen den stromführenden Bereich 14 und schließen somit einen zweiten Strompfad 18 zur Versorgung des Kontaktbereichs 8 mit Strom bzw. zur Gewährleistung der geforderten Stromtragfähigkeit. Auf der von dem (unteren) freien Ende 13 abgewandten (Ober-) Seite des stromführenden Bereichs 14 befindet sich ein abgeschrägtes, (oberes) freies Ende 15 des Streifenabschnittes 12. Dieses bildet eine Verriegelungsfeder 16, die im eingesteckten Zustand des Leistungs-Steckkontaktes 1 ein Herausziehen entgegen der Einsteckrichtung 10 durch Herstellung eines Formschlusses sicher verhindert. Um ein unbeabsichtigtes Lösen der Verriegelungsfeder 16 zu verhindern, sind dieser Sekundärverriegelungsmittel 19 in Form einer Metallebene zugeordnet, die von der Verriegelungsfeder 16 im verriegelten Zustand hintergriffen wird, sodass ein zerstörungsfreies Lösen des einmal eingesteckten Leistungs-Steckkontaktes 1 quasi unmöglich wird.As can be seen in particular from FIG. 3, the multi-part contact region 8 is formed on a bent strip section 12 of the power plug contact 1, which forms the spring means 9 simultaneously with its lower region facing the printed conductor 2. As can be seen from FIG. 3, the strip section 12 is longitudinally slotted in the region of the spring means 9 or in the contact region 8, ie formed by two spring means 9 which are adjustable relative to one another and lies in the region of its lower, free right in the plane of the drawing Endes 13 at one in a formed as a flat portion current-carrying region 14, wherein the current-carrying region 14 as viewed in the insertion direction 10 between the connecting means 6 and the contact region 8 is located. In the event that the power plug contact 1 is not plugged in and thus the spring means 9 are not subjected to force, and thus generate no contact force as a counterforce, the free end 13 of the spring means 9 is spaced from the current-carrying region 14. By inserting the power plug-in contact 1 and the associated application of force, the spring means 9 pivot with their free end 13 (from below) against the current-carrying region 14 and thus close a second current path 18 for supplying the contact region 8 with power or to ensure required current carrying capacity. On the (upper) side facing away from the (lower) free end 13 of the current-carrying portion 14 is a bevelled, (upper) free end 15 of the strip portion 12. This forms a locking spring 16, which in the inserted state of the power plug contact. 1 a withdrawal against the insertion direction 10 by producing a positive connection safely prevented. In order to prevent unintentional release of the locking spring 16, these secondary locking means 19 are assigned in the form of a metal level, which is engaged behind by the locking spring 16 in the locked state, so that a non-destructive release of the once inserted power plug contact 1 is virtually impossible.
Wie sich insbesondere aus den Fig. 1 und 2 ergibt, ist der Streifenabschnitt 12 aufgenommen zwischen zwei parallel zueinander angeordneten Schutzwänden 21, 22, die den vorderen, gebogenen Abschnitt 20 in Einsteckrichtung 10 überragen. Die Flächenerstreckung der Schutzwände 21, 22 verläuft im Wesentlichen senkrecht zu den Flächenerstreckungen der Ober- und Unterseite des Streifenabschnittes 12. Zur Erhöhung der Robustheit des Leistungs-Steckkontaktes sind die Schutzwände 21, 22 jeweils über drei Schweißpunkte 23 mit dem Streifenabschnitt 12 verbunden. Von den Schutzwänden 21, 22 wird zusammen mit dem Streifenabschnitt 12 eine Art robuster (Hohl-) Kasten gebildet.As is apparent in particular from FIGS. 1 and 2, the strip section 12 is received between two mutually parallel protective walls 21, 22, which project beyond the front, bent section 20 in the insertion direction 10. The surface extension of the protective walls 21, 22 extends substantially perpendicular to the surface extensions of the upper and lower sides of the strip section 12. To increase the robustness of the power plug contact, the protective walls 21, 22 are each connected to the strip section 12 via three spot welds 23. Of the protective walls 21, 22, a kind of robust (hollow) box is formed together with the strip portion 12.
Wie sich aus Fig. 3 ergibt, wird ein erster Strompfad 17, zu dem bei Kraftbeaufschlagung der Federmittel 9 ein zwei- ter Strompfad 18 hinzugeschaltet wird, im Wesentlichen gebildet von dem stromführenden Bereich 14, den Schutzwänden 21, 22, den Schweißpunkten 23, dem oberen Abschnitt (Oberseite) des Streifenabschnitts 12 sowie einem von dem gebo- genen Abschnitt 20 des Streifenabschnitts 12. Der zweite Strompfad 18 wird bei eingestecktem Leistungs-Steckkontakt 1 gebildet von dem stromführenden Bereich 14 sowie dem Bereich des Stromabschnitts 12 zwischen dem stromführenden Bereich 14 und dem Kontaktbereich 8. Im eingesteckten Zustand stützt sich der Leistungs-Steckkontakt 1 mit der Oberseite des Streifenabschnittes 12, vorzugsweise in etwa gegenüberliegend des Kontaktbereichs 8, an einer nicht gezeigten Kunststofffläche ab, die derart angeordnet ist, dass die Federmittel 9 senkrecht zur Einsteckrichtung 10 zusammengedrückt werden und somit den zweiten Strompfad 18 freischaltet .As can be seen from FIG. 3, a first current path 17, to which a second current path 18 is connected upon application of force to the spring means 9, is essentially formed by the current-carrying region 14, the protective walls 21, 22, the welding points 23, upper portion (upper side) of the strip portion 12 and one of the bent The second current path 18 is formed with the power plug-in contact 1 plugged in by the current-carrying region 14 and the region of the current section 12 between the current-carrying region 14 and the contact region 8. When plugged in, the power plug contact 1 is supported with the top of the strip portion 12, preferably approximately opposite the contact region 8, on a plastic surface, not shown, which is arranged such that the spring means 9 are compressed perpendicular to the insertion direction 10 and thus the second current path 18 is released.
Wie sich aus Fig. 1 ergibt, ist die in der Zeichnungsebene vordere Schutzwand 22 als Steckerkodierung 24 ausgebildet, die ein korrekt orientiertes Einschieben des Leistungs- Steckkontaktes 1 gewährleisten soll. As is apparent from Fig. 1, the front in the plane of the protective wall 22 is formed as a male coding 24, which is to ensure a correctly oriented insertion of the power plug-in contact 1.
