Description
Die Erfindung bezieht sich auf einen Hochspannungsschal ter nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a high-voltage scarf ter according to the preamble of claim 1.
Ein derartiger Hochspannungsschalter ist aus der US 5 109 829 bekannt. Die Halbleiterbauelemente sind am Boden eines Kegels angeordnet, an dessen Spitze das lichtemittierende Element sitzt. Der Kegel wiederum ist innerhalb eines Gehäuses ausgeformt, das außerhalb des Kegels mit einem Füllmaterial versehen ist. Dadurch er gibt sich ein aufwendiger Aufbau und ein relativ großes Gewicht. Ferner ist es dann, wenn eine größere Anzahl von Halbleiterbauelementen optisch gezündet werden sollen, erforderlich, eine entsprechende Anzahl von lichtemittie renden Elementen vorzusehen, was die Kosten, das Gewicht und den erforderlichen Bauraum des Schalters negativ be einflußt.Such a high voltage switch is from the US 5 109 829 known. The semiconductor devices are on Bottom of a cone arranged at the top of the light-emitting element sits. The cone is in turn molded inside a housing that outside the Cone is provided with a filling material. Thereby he is a complex structure and a relatively large Weight. Furthermore, it is when a larger number of Semiconductor components are to be ignited optically, required an appropriate number of light emitters elements, what the cost, the weight and the required installation space of the switch be negative influences.
Der Erfindung liegt die Aufgabe zugrunde, ein Hochspan nungsschalter der eingangs genannten Art zu schaffen, der sich durch einen gedrängten Bauraum und einen einfachen konstruktiven Aufbau auszeichnet.The invention has for its object a high chip to create voltage switch of the type mentioned, the through a compact space and a simple constructive structure.
Die Erfindung löst diese Aufgabe durch die kennzeichnen den Merkmale des Patentanspruchs 1.The invention solves this problem by characterizing the features of claim 1.
Durch die Anordnung der Halbleiterbauelemente um das lichtemittierende Element herum hängt die Zahl der op tisch durch das lichtemittierenden Element zündbaren Halbleiterbauelemente nicht vom Abstand zu dem, sondern von der Größe der Oberfläche des lichtemittierenden Ele ments ab. Anstelle einer LED wie beim bekannten Hoch spannungsschalter bietet sich hierfür eine Xenonröhre an: Diese besitzt eine hohe Lichtstärke bei gutem Zündverhal ten und ist einfach und robust im Aufbau und der Handha bung.By arranging the semiconductor components around the light-emitting element around depends on the number of op ignitable by the light-emitting element Semiconductor components not from the distance to that, but on the size of the surface of the light-emitting ele from. Instead of an LED like the well-known high A xenon tube is the ideal switch for this: This has a high light intensity with good ignition behavior and is simple and robust in construction and handling exercise.
Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Patentansprüchen beschrieben. Dabei ist insbe sondere die im Patentanspruch 6 angegebene Möglichkeit, den Hochspannungsschalter in einem Zündkerzenstecker zu integrieren, für den Einsatz bei Kraftfahrzeugen von be sonderer Bedeutung. Dadurch ergibt sich die Möglichkeit, von einer Zündspule ausgehend unter Verwendung derartiger Zündkerzenstecker die Zündkerzen zylinderselektiv an die Hochspannung anzuschließen. Der hierfür pro Zündkerze er forderliche zusätzliche Bauraum ist relativ gering und stellt sich äußerlich lediglich als axiale Verlängerung des Zündkerzenanschlußsteckers dar.Advantageous embodiments of the invention are in the further claims described. Here is esp special the possibility specified in claim 6, the high-voltage switch in a spark plug connector integrate, for use in motor vehicles from be of particular importance. This gives the opportunity starting from an ignition coil using such To the spark plugs Connect high voltage. The one for each spark plug required additional space is relatively small and is only an external extension of the spark plug connector.
In der Zeichnung ist ein Ausführungsbeispiel der Erfin dung dargestellt. Es zeigtIn the drawing is an embodiment of the Erfin shown. It shows
Fig. 1 einen erfindungsgemäßen Hochspannungsschalter in der Abwicklung und Fig. 1 a high-voltage switch according to the invention in the settlement and
Fig. 2 den Hochspannungsschalter von Fig. 1 eingebaut in einen Zündkerzenstecker und im Querschnitt. Fig. 2 shows the high-voltage switch of Fig. 1 installed in a spark plug connector and in cross section.
Der in Fig. 1 dargestellte Hochspannungsschalter 1 wirkt als Thyristor und besteht aus insgesamt 48 Halbleiterbau elementen, die in sechs Reihen zu acht Elementen auf Trä gerplatten 3₁ bis 3₆ angeordnet sind. Jeder der Halblei terbauelemente besitzt eine Sperrspannung von 1200 V. Die Bauelemente sind mäanderförmig wie dargestellt hinterein andergeschaltet. The high-voltage switch 1 shown in Fig. 1 acts as a thyristor and comprises a total of 48 semiconductor assembly members which are arranged gerplatten 3 ₁ to 3₆ in six rows of eight elements to Trä. Each of the semiconductor components has a reverse voltage of 1200 V. The components are meandering in series as shown.
Die Trägerplatten 3₁ bis 3₆ sind, wie in Fig. 2 gezeigt, zu einem Sechskant miteinander verbunden und verklebt. Sie umgeben eine Xenonröhre 4 konzentrisch. Zwischen je weils zwei benachbarten Trägerplatten sind Stege 5 einge setzt, um einen Spannungsüberschlag zwischen zwei Halb leiterbauelementen auf unterschiedlichen Trägerplatten zu verhindern. Der gesamte Raum zwischen der Xenonröhre und den Trägerplatten 3₁ bis 3₆ ist mit durchsichtigem, hoch isoliertem Gießharz vergossen.The carrier plates 3 ₁ to 3₆ are, as shown in Fig. 2, connected to each other to a hexagon and glued. They surround a xenon tube 4 concentrically. Between each two adjacent carrier plates, webs 5 are inserted in order to prevent a flashover between two semiconductor components on different carrier plates. The entire space between the xenon tube and the support plates 3 ₁ to 3₆ is potted with transparent, highly insulated casting resin.
Die in Fig. 2 dargestellte Anordnung befindet sich in ei nem nicht gezeigten Zündkerzenanschlußstecker, dessen Hochspannungsanschluß mit dem zur Trägerplatte 3₁ führen den elektrischen Leiter 6 verbunden ist und dessen Zünd kerzenanschlußkontakt (nicht dargestellt) mit dem Ende dieses Leiters 7 verbunden ist.The arrangement shown in Fig. 2 is in egg nem not shown spark plug connector, the high voltage connection with the lead to the carrier plate 3 ₁ the electrical conductor 6 is connected and the ignition plug connector contact (not shown) is connected to the end of this conductor 7 .
Um die am Leiter 7 angeschlossene Zündkerze mit der Hoch spannung, d. h. dem Hochspannungsanschluß einer nicht dar gestellten Zündspule zu verbinden, wird die Xenonröhre 4 gezündet. Die Halbleiterbauelemente 2 werden damit sämt lich leitend. Ein Hochspannungsimpuls kann nun vom Leiter 6 durch die Halbleiterbauelemente 2 zum Leiter 7 und da mit zur Zündkerze gelangen. Beim anschließenden Strom durchgang durch Null werden die Halbleiterbauelemente wieder nicht-leitend und können erst durch einen erneuten Zündvorgang der Xenonröhre gezündet werden.In order to connect the spark plug connected to the conductor 7 to the high voltage, ie the high voltage connection of an ignition coil (not shown), the xenon tube 4 is ignited. The semiconductor devices 2 are all Lich Lich conductive. A high-voltage pulse can now pass from conductor 6 through semiconductor components 2 to conductor 7 and there to the spark plug. When the current passes through zero, the semiconductor components become non-conductive again and can only be ignited by a renewed ignition process of the xenon tube.
Für eine nicht dargestellte Brennkraftmaschine mit mehre ren Zylindern genügt eine einzige Zündspule als Hochspan nungsquelle. Die zylinderselektive Zuordnung der Hoch spannung zu den einzelnen Zylindern erfolgt mit Hilfe des dargestellten Hochspannungsschalters für jeden der Zylin der. Durch gleichzeitige Zündung der Hochspannungsschal ter für zwei Zylinder ist es auch möglich, z. B. beim Kaltstart zwei Zündkerzen gleichzeitig zu zünden. Gegen über einem Zündsystem, bei dem jeder Zylinder mit einer Einzelspulenzündung versehen ist, ergibt sich damit eine erhebliche Gewichts- und Kostenersparnis, da nur noch eine gemeinsame Zündspule und für jede Zündkerze ein Zündkerzenstecker vorgesehen werden muß, der einen Hoch spannungsschalter gemäß der Erfindung aufweist.For an internal combustion engine, not shown, with several ren cylinders, a single ignition coil is sufficient as a high voltage source of supply. The cylinder-selective assignment of the high The individual cylinders are tensioned using the High voltage switch shown for each of the Zylin the. By simultaneously igniting the high voltage scarf ter for two cylinders, it is also possible, for. B. at Cold start to ignite two spark plugs at the same time. Against over an ignition system in which each cylinder with a Single coil ignition is provided, this results in a considerable weight and cost savings, since only a common ignition coil and one for each spark plug Spark plug connector must be provided which is a high Has voltage switch according to the invention.
