Abstract
Description
Die Erfindung betrifft eine elektrische Schaltung mit streifenförmigen Leitern aus Blech, die ein Stanzgitter bilden und Löcher zur Kontaktierung mit Kontaktstiften aufweisen.The invention relates to an electrical circuit with strip-shaped conductors Sheet that form a lead frame and holes for contacting with contact pins exhibit.
In elektronischen Geräten, in denen auch hohe Ströme geleitet werden, sind die üblichen Leiterplattentechniken ungünstig bzw. teuer. Deshalb werden zur Leitung hoher Ströme, beispielsweise in Steuergeräten für Kraftfahrzeuge, Stanzgitter verwendet, die aus streifenförmigen Leitern hergestellt sind. Die Kontaktierung dieser Leiter mit anderen Bauteilen erfolgt durch Schweißen oder Löten, was wiederum aufwendig und teuer ist.These are in electronic devices in which high currents are also conducted usual circuit board technologies unfavorable or expensive. That is why become the lead high currents, for example in control units for motor vehicles, lead frames used, which are made of strip-shaped conductors. The contacting this conductor with other components is made by welding or soldering, which in turn is complex and expensive.
Aufgabe der vorliegenden Erfindung ist es, elektrische Schaltungen, in denen hohe Ströme geführt werden, insbesondere Steuer- und Regelgeräte für Kraftfahrzeuge, preisgünstig herzustellen, wobei zuverlässige elektrische Verbindungen innerhalb der Geräte sichergestellt sein müssen.The object of the present invention is to provide electrical circuits in which high currents are carried, in particular control and regulating devices for motor vehicles, inexpensive to manufacture, with reliable electrical connections must be ensured within the devices.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Löcher durch Fließpressen hergestellte Ausformungen aufweisen, deren Tiefe größer als die Blechdicke ist und deren Durchmesser derart gewählt ist, daß die Löcher Einpreßbohrungen für die Kontaktstifte darstellen.This object is achieved in that the holes through Extrusions produced formations, the depth of which is greater than that Sheet thickness is and the diameter is chosen such that the holes Represent press-in holes for the contact pins.
Die Erfindung weist den Vorteil auf, daß die Montage wesentlich vereinfacht wird und daß eine Reduzierung von Übergangswiderständen in den Kontaktzonen erfolgt.The invention has the advantage that the assembly is considerably simplified and that a reduction in contact resistance in the contact zones he follows.
Vorzugsweise ist bei der erfindungsgemäßen Schaltung vorgesehen, daß die streifenförmigen Leiter aus vorverzinntem Blech bestehen. Damit ergibt sich nach dem Fließpressen automatisch eine verzinnte Bohrung.It is preferably provided in the circuit according to the invention that the strip-shaped conductors made of pre-tinned sheet metal. This results in a tinned hole automatically after extrusion.
Ferner ist bei der erfindungsgemäßen Schaltung vorzugsweise vorgesehen, daß die streifenförmigen Leiter aus einer Kupferlegierung bestehen. Damit sind eine gute elektrische Leitfähigkeit und eine gute Verformbarkeit gewährleistet.Furthermore, it is preferably provided in the circuit according to the invention that that the strip-shaped conductors consist of a copper alloy. With that ensures good electrical conductivity and good ductility.
Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Schaltung besteht darin, daß die Kontaktstifte die streifenförmigen Leiter mit einer Hybridschaltung verbinden.There is an advantageous embodiment of the circuit according to the invention in that the contact pins are the strip-shaped conductors with a hybrid circuit connect.
Die Erfindung läßt zahlreiche Ausführungsformen zu. Eine davon ist schematisch in der Zeichnung anhand mehrerer Figuren dargestellt und nachfolgend beschrieben. Es zeigt:
- Fig. 1
- einen Teil eines Stanzgitters mit einer erfindungsgemäß ausgeführten Einpreßbohrung,
- Fig. 2
- den gleichen Teil des Stanzgitters mit aufgeschnittener Einpreßbohrung und
- Fig. 3
- einen Längsschnitt durch die Einpreßbohrung.
- Fig. 1
- part of a lead frame with a press-in bore designed according to the invention,
- Fig. 2
- the same part of the leadframe with cut-open hole and
- Fig. 3
- a longitudinal section through the press-in bore.
Stanzgitter bestehen in der Regel aus mehreren voneinander isolierten Leitern,
weshalb sie in verschiedenen Ebenen verlaufen. Der dargestellte Teil des
Stanzgitters 1 ist daher bei 2 gekröpft, um Kreuzungen zu ermöglichen. Der
Arm 3 des Stanzgitters 1 ist mit einem Auge 4 versehen, in das eine Bohrung 5
mit einer Ausformung 6 durch Fließpressen eingefügt ist. Der Innendurchmesser
D der Bohrung 5 ist derart gewählt, daß die Voraussetzungen zu einem
Einpressen vorliegen, das heißt, daß genügend Druckspannung zwischen dem
Innenrand der Bohrung und dem in den Figuren nicht dargestellten Kontaktstift
vorliegt, daß jedoch die Kraft zum Einpressen nicht zu einer Verformung und
Beschädigung des Kontaktstiftes führt. In Fig. 3 ist die Zinnschicht 7 angedeutet.Punched grids usually consist of several insulated conductors,
which is why they run at different levels. The part shown
Lead frame 1 is therefore cranked at 2 to enable crossings. The
