Abstract
Description
Stand der TechnikState of the art
Die Erfindung betrifft ein Bauteil, insbesondere eine Diode mit erhöhter Stabilität, die dazu geeignet ist, als Leistungsdiode in einen Gleichrichter für einen Generator eingebaut zu werden.The The invention relates to a component, in particular a diode with increased Stability, which is suitable as a power diode in to be installed a rectifier for a generator.
Es
ist bekannt, für die Gleichrichtung der Kfz-Generatorspannung
eine sechspulsige Brückenschaltung zu verwenden. Die Gleichrichterbrücke
besteht dabei aus mindestens sechs Dioden oder Zenerdioden, welche
in einen Kühlkörper eingepresst sind. Solche Einpressdioden
bestehen prinzipiell aus zwei Gehäuseteilen, einem Kopfdraht
und einem Sockel, wobei zwischen diesen beiden Gehäuseteilen ein
Siliziumchip mit Diodenfunktion eingelötet ist. Solche
Einpressdioden sind beispielsweise aus der
Da
der Generator üblicherweise in der Nähe des Motors
des Fahrzeugs angeordnet ist bzw. durch den direkten Anbau am Motor,
kommt es zu hohen dynamischen Belastungen der einzelnen Baugruppen
des Generators und damit des ihm zugeordneten Gleichrichters bzw.
der Dioden. Besonders der Kopfdraht der Diode ist wegen seiner Länge
bezüglich Schwingung gefährdet und kann an der Übergangsstelle
bzw. dem Übergangsbereich zur Vergussmasse brechen.
Auch an der Schweißstelle zur Verschaltungsplatte des Gleichrichters kann der Kopfdraht einer Diode mit herkömmlicher Ausgestaltung brechen, da der Kopfdraht an dieser Stelle durch den Schweißvorgang geschwächt sein kann.Also at the welding point to the wiring plate of the rectifier For example, the head wire of a diode of conventional design Break, as the head wire at this point by the welding process can be weakened.
Durch den Schweißprozess, der beispielsweise als Widerstandsschweißen durchgeführt wird, kommt es zu einer Verhärtung bzw. Versprödung im Schweißbereich, die im Kopfdraht zu einer erhöhten Bruchgefahr führt.By the welding process, for example, as resistance welding is carried out, it comes to a hardening or embrittlement in the welding area, in the head wire leads to an increased risk of breakage.
Offenbarung der ErfindungDisclosure of the invention
Es ist die Aufgabe der Erfindung, die Kopfdrahtgeometrie für Dioden, insbesondere Leistungsdioden so zu ändern, dass sich das Gewicht des Kopfdrahtes bzw. der Leistungsdiode gegenüber herkömmlichen Leistungsdioden nicht erhöht, jedoch eine verbesserte Stabilität erhalten wird. Gelöst wird diese Aufgabe durch eine Diode mit den Merkmalen des Anspruchs 1.It The object of the invention, the head wire geometry for Diodes, especially power diodes to change so that the weight of the head wire or the power diode opposite conventional power diodes not increased, but one improved stability is obtained. This is solved Task by a diode having the features of claim 1.
Die Vorteile der Erfindung sind darin zu sehen, dass eine verbesserte dynamische Festigkeit des Kopfdrahtes erhalten wird. Die verbesserte Festigkeit wird dabei in vorteilhafter Weise an beiden gefährdeten Stellen des Kopfdrahtes erhalten, als im Übergangsbereich zum Kopfdrahtteller bzw. im Übergangsbereich zur Vergussmasse und in dem Bereich, in dem der Kopfdraht eine Verstärkung bzw. einen größeren Durchmesser aufweist. In vorteilhafter Weise kann das erfindungsgemäße Bauteil, insbesondere der Kopfdraht einer Diode, weiterhin mittels Kaltverformung hergestellt werden. Erzielt werden diese Vorteile durch ein Bauelement mit den Merkmalen des Anspruchs 1.The Advantages of the invention are to be seen in that an improved dynamic strength of the head wire is obtained. The improved Strength is thereby vulnerable to both To get places of the head wire, than in the transition area to the head wire plate or in the transition region to the potting compound and in the area where the head wire has a reinforcement or has a larger diameter. In an advantageous way can the component according to the invention, in particular the head wire of a diode, further manufactured by cold deformation become. These advantages are achieved by a component with the Features of claim 1.

Vergrößerung ist der Chip
Da die Rotationssymmetrie weiterhin erhalten bleibt, das heißt der ursprüngliche Fertigungsprozess wird nicht geändert, wird zur Herstellung der Diode bzw. des Kopfdrahtes lediglich ein neues Werkzeug benötigt.There the rotational symmetry is still preserved, that is the original manufacturing process is not changed is for the production of the diode or the head wire only one new tool needed.
Die
erfindungsgemäßen Dioden lassen sich in herkömmliche
Gleichrichter einsetzen. Dabei werden die Dioden in dafür
vorgesehene Öffnungen des Gleichrichters so eingepresst,
dass der aus der Vergussmasse ragende Kopfdraht
Berücksichtigt werden muss jedoch, dass sich das Gesamtgewicht des Kopfdrahtes nicht erhöht, da es ansonsten zu Problemen beim Einlöten des Siliziumchips kommen kann. Ist der Kopfdraht zu schwer, wird Lot im flüssigen Zustand zwischen dem Kopfdraht und dem Chip herausgedrückt. Dies könnte zu einem Kurzschluss des Chips führen.Considered However, that must be the total weight of the head wire not increased, otherwise there are problems with the soldering of the Silicon chips can come. If the head wire is too heavy, becomes solder in the liquid state between the head wire and the chip pushed out. This could cause a short circuit lead the chip.
Als vorteilhafte Ausgestaltungen der Diode sind folgende Ausführungsformen möglich:
- 1. Der Kopfdraht
10 hat über die komplette Länge von beispielsweise 19,2 mm einen Durchmesser von 2 mm. Dies führt insgesamt zu einem Gewicht von ca. 1,1 Gramm. Bisher gebräuchliche Dioden wiegen ca. 0,7 Gramm. Eine deratige Ausgestaltung ist leicht fertigbar, da konstruktiv nur der Durchmesser bezüglich herkömmlicher Dioden zu ändern ist. - 2. Der Kopfdraht
10 ist, wie in4 dargestellt, nur am oberen Ende und am Übergang zum Kopfdrahtteller jeweils über eine Länge von 5 mm verstärkt. Der Durchmesser beträgt jeweils 2 mm, in der Mitte 1,3 mm wie bisher.
- 1. The head wire
10 has a diameter of 2 mm over the complete length of for example 19.2 mm. This leads to a total weight of about 1.1 grams. Previously used diodes weigh about 0.7 grams. A deratige design is easily manufacturable, since constructively only the diameter is to change with respect to conventional diodes. - 2. The head wire
10 is how in4 shown, reinforced only at the upper end and at the transition to the head wire plate each over a length of 5 mm. The diameter is 2 mm in each case, in the middle 1.3 mm as before.
Für die Ausführungsformen 1 und 2 gilt: die Tragfähigkeit des Bleilotes (PbSn4), welches sich zwischen Kopfdraht und Chip sowie Sockel und Chip befindet, beträgt ca. 0,1 g/mm2. Hieraus ergibt sich für den Kopfdraht (bei konstanter Fläche der Unterseite des Kopfdrahtes) ein maximales Gewicht von ca. 5 Gramm.For Embodiments 1 and 2 are: the carrying capacity of the lead note (PbSn4), which is located between the head wire and the chip as well as socket and chip is, amounts to approx. 0.1 g / mm2. This results for the head wire (with constant area the underside of the head wire) has a maximum weight of about 5 Grams.
