Abstract

Electrical connections (16, 17) between the electrodes of a capacitor body (10) and electrical connections (18, 19) of the capacitor are produced from metal clamps which are aligned essentially parallel to one another and in a line in order to form an electrical parallel circuit and to reduce the inductance of the capacitor. <IMAGE>

Description

Kondensator mit geringer Induktivität Low inductance capacitor

Die vorliegende Erfindung betrifft einen Kondensator nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a capacitor according to the preamble of claim 1.

Zur Herabsetzung der Induktivität ist ein derartiger Kondensator erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gekennzeichnet. Such a capacitor is used to reduce the inductance according to the invention by the features of the characterizing part of the claim 1 marked.

Ausgestaltungen des Erfindungsgedankens sind in Unteransprüche gekennzeichnet.Refinements of the inventive concept are characterized in the subclaims.

Die Erfindung wird im folgenden anhand eines in den Figuren wider Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigt: Fig. 1 eine teilweise geschnittene Ansicht eines erfindungsgemäßen Kondensators; und Fig. 2 eine Ansicht in einer Ebene 2-2 in Fig. 1.The invention is reflected below with reference to one in the figures Drawing illustrated embodiment explained in more detail. It shows: Fig. 1 a partially sectioned view of a capacitor according to the invention; and FIG. 2 a view in a plane 2-2 in FIG. 1.

Gemäß den Figuren der Zeichnung, ist eine elektronische Komponente, wie beispielsweise ein Wickelkondensatorkörper 10 im wesentlichen von zylindrischer Gestalt, wobei ein Teil in seinem Zentrum 11 ausgespart ist, um auf ein angespitztes Element 12 aufgesetzt zu werden, das vom Boden eines Gehäuses 20 ausgeht. In der dargestellten Ausführungsform wird der Körper 10 durch eine mit einem absorbierenden Material 15, wie beispielsweise Papier verwickelte Aluminiumfolienschicht 14, gebildet. Der Körper ist mit einem flüssigen Elektrolyten, wie beispielsweise einer Verbindungsmischung, die im wesentlichen aus Äthylenglykol und Borsäure besteht, imprägniert. Die Ausgestaltung des Körpers 10 ist jedoch nicht auf diese Ausführungsform beschränkt. Ein Paar von Anschlußleitungen 16 und 17 gehen vom Körper 10 aus und sind über geeignete Elemente, wie beispielsweise Nieten oder durch Schweißen mit einzelnen elektrischen Anschlüssen 18 und 19 verbunden. Das Gehäuse 20 besitzt ein durch einen Bördelrand 22 gebildetes offenes Ende 21. Dieses Ende 21 ist durch eine Kunststoffkappe 23 verschlossen, um das vollständige Gehäuse zu realisieren.According to the figures of the drawing, is an electronic component, such as a wound capacitor body 10 is essentially cylindrical Shape, with a part being recessed in its center 11, in order to point to a pointed Item 12 to be placed on the floor a housing 20 goes out. In the illustrated embodiment, the body 10 is through a with an absorbent material 15 such as a paper wrapped aluminum foil layer 14, formed. The body is using a liquid electrolyte, such as a compound mixture consisting essentially of ethylene glycol and boric acid, impregnated. However, the configuration of the body 10 is not limited to this embodiment limited. A pair of leads 16 and 17 extend from the body 10 and are via suitable elements, such as rivets or by welding with individual electrical connections 18 and 19 connected. The housing 20 has a formed by a bead 22 open end 21. This end 21 is through a Plastic cap 23 closed in order to realize the complete housing.

Die Kunststoffkappe 23 trägt die Anschlüsse 18 und 19.The plastic cap 23 carries the connections 18 and 19.

Erfindungsgemäß sind die Anschlußleitungen 16 und 17 so ausgebildet, daß sie einen Parallel-Widerstands/Kapazitäts-Kreis in einem Raum 30 zwischen dem Kondensatorkörper 10 und dem Gehäuse 20 bilden. Die Leitungen sind dünne Metallschellen, so daß sie beim Einbringen der Kunststoffkappe 23 in die zum Schließen des Gehäuses 20 vorgesene Stellung (Fig. 2) so gedrückt werden, daß sie übereinander und zueinander ausgerichtet zu liegen kommen. Ein geeignetes Material für die Metallschellen ist beispielsweise Aluminium mit einer Dicke von 0,03048 cm. Eine elektrische Isolationsschicht 32 isoliert die Schellen elektrisch voneinander.According to the invention, the connecting lines 16 and 17 are designed so that that they have a parallel resistance / capacitance circuit in a space 30 between the Form the capacitor body 10 and the housing 20. The lines are thin metal clamps, so that when the plastic cap 23 is inserted into the for closing the housing 20 vorgesene position (Fig. 2) are pressed so that they are on top of each other and to each other come to rest aligned. A suitable material for the metal clamps is for example aluminum with a thickness of 0.03048 cm. An electrical insulation layer 32 electrically isolates the clamps from one another.

Ein geeignetes Material für die Isolationsschicht 32 ist beispielsweise Polypropylen mit einer Dicke von 0,0254 cm.A suitable material for the insulation layer 32 is, for example Polypropylene 0.0254 cm thick.
