Description
Entladungsgefäß Zusatz zum Zusatzpatent 689 6o9 In dem Hauptpatent 689 6o9 ist ein Entladungsgefäß beschrieben, dessen Gefäßwand zum Teil aus einem einseitig geschlossenen Metallzylinder besteht, der gleichzeitig als Anode dient. Dieser Metallzylinder ist an seinem offenen Ende durch einen Glasdeckel verschlossen, der mittels einer Ringquetschung mit einem an dem unteren Rande des Metallringes eingeschmolzenen Glasflansch verbunden ist. Die Zuführungen zu den inneren Elektroden werden dabei in die Ringquetschung eingebettet und dienen bei geeigneter Ausbildung gleichzeitig zur Abstützung des inneren Elektrodensystems. Die auf diesem Wege erhaltenen Vorteile bestehen vor allem in einer Verringerung der Abmessungen, insbesondere der Bauhöhe der Röhre, und in einer Vereinfachung der Herstellung. Diese Bauart bringt es allerdings, mit sich, daß die in die Ringquetschung eingeschmolzenen Elektrodenzuführungen einen geringen Abstand von der Anode und daher eine größere Kapazität gegen diese besitzen., als es in mang chen Fällen wünschenswert ist: Unter Umständen wird dies, insbesondere hinsichtlich der Kapazität zwischen Steuergitter und Anode, als Nachteil empfunden, der durch die vorliegende Erfindung beseitigt werden soll.Discharge vessel addition to additional patent 689 6o9 in the main patent 689 609 describes a discharge vessel, the vessel wall of which is partly made of a There is a metal cylinder closed on one side, which also serves as an anode. This metal cylinder is closed at its open end by a glass lid, by means of a ring pinch with one on the lower edge of the metal ring melted glass flange is connected. The leads to the inner electrodes are embedded in the ring squeeze and are used with suitable training at the same time to support the inner electrode system. The ones obtained in this way The main advantages are a reduction in dimensions, in particular the overall height of the tube, and in a simplification of the production. This type It does, however, mean that the electrode leads melted into the pinched ring a small distance from the anode and therefore a greater capacitance against it than it is desirable in a lack of cases: Under certain circumstances this will especially with regard to the capacitance between control grid and anode, as a disadvantage felt, which is to be eliminated by the present invention.
Erfindungsgemäß werden daher bei einem Entladungsgefäß gemäß dem Hauptpatent 689 6o9 eine oder mehrere Elektrodenzuleitungen nicht durch die Ringquetschung, sondern auf der dem Metallzylinder abgekehrten Seite der Ringquetschung durch den Glasdeckel herausgeführt.According to the invention, therefore, in a discharge vessel according to the main patent 689 6o9 one or more electrode leads not through the ring pinch, but on the side of the ring squeezing away from the metal cylinder by the Glass lid led out.
Ein. Ausführungsbeispiel des Erfindungsgedankens zeigt die Abbildung.A. The figure shows an embodiment of the inventive concept.
Es bedeutet i einen oben verschlossenen Metallzylinder, der unten erweitert und dort mit einem in einen Flansch übergehenden Glasring 2 verbunden ist. Der Abschluß des Entladungsgefäßes erfolgt durch einen Glasdeckel 3, der mit dem Flansch des Glasringes a durch eine Ringquetschung verbunden isst. Das Elektrodensys-tem umfa 3t außer denn als Elektrode dienenden Metallzylinder i noch eine Steuerelektrode q. und eine beispielsweise indirekt geheizte Kathode 5, welche durch zwei Isolierbrücken .6 und 7 distanziert und gegen die Anode abgestützt werden. Der Kathodenanschluß 8, der so starr ausgebildet werden kann, daß er die Lage des Elektrodensystems in axialer Richtung sichert, und die Zuführungen zu dem Heizelement der Kathode sind in die Ringquetschung eingebettet- Die Zuführung zum Steuergitter verläuft durch den Glasdsckel3 hindurch. Im vorliegenden Beispiel ist eine Gitterstütze 9 entsprechend verlängert und führt durch den Pumpstutzen i o, der nach Fertigstellung der Röhre in üblicher -Weise zugeschmolzen wird. Die Gitterzuleitung kann -aus einem verhältnismäßig dicken Draht bestehen, wodurch für eine rasche Abfuhr der dem Gitter durch Strahlung von der Kathode her mitgeteilten Wärme gesorgt ist. Das Gitter nimmt infolgedessen keine hohe Temperatur an und zeigt daher wenig Neigung zu thermischer Emission. Falls der Durchmesser so groß gewählt wird, daß eine vakuumdichte Einschinelzung an der Durchführungsstelle nicht mehr gewährleistet erscheint, erreicht man denselben Zweck dadurch, daß man nur das Ende der dicken Stütze in das Glas einbettet und diese dann durch einen dünneren Einschmelzäraht fortsetzt. In diesem Falle teilt sich die Wärme der betreffenden Elektrode dem Glasteil mit, und gleichzeitig ist noch immer für eine stabile Halterung gesorgt. Diese Ausführungsform läßt sich gerade im vorliegenden Falle mit besonderem Vorteil anwenden, da die dicken Elektrodenstützen nicht oder nur wenig gebogen zu werden. brauchen und sich daher durch besondere Starrheit auszeichnen.It means i a metal cylinder closed at the top, the one below expanded and there connected to a glass ring 2 merging into a flange is. The discharge vessel is closed by a glass cover 3, which is with the flange of the glass ring a is connected by a ring pinch. The electrode system In addition to the metal cylinder serving as an electrode, it also includes a control electrode q. and an, for example, indirectly heated cathode 5, which is connected by two insulating bridges .6 and 7 are distanced and supported against the anode. Of the Cathode connection 8, which can be made so rigid that it can accommodate the position of the electrode system in axial direction secures, and the leads to the heating element of the cathode embedded in the ring pinch - the feed to the control grid runs through through the glass lid3. In the present example, a grid support 9 is corresponding extends and leads through the pump nozzle i o, which after completion of the tube is melted shut in the usual way. The grid feed line can -of a relatively thick wire are made, allowing for a quick dissipation of the grid by radiation from the cathode communicated heat is taken care of. The grid increases as a result does not indicate a high temperature and therefore shows little tendency towards thermal emissions. If the diameter is chosen to be so large that a vacuum-tight Eininelzung no longer appears to be guaranteed at the implementation point, the same can be reached Purpose by embedding only the end of the thick support in the glass and this then continues through a thinner fuse wire. In this case it shares the heat of the electrode concerned is the glass part with, and is at the same time still provided for a stable bracket. This embodiment can be straight in the present case use it with particular advantage, as the thick electrode supports not to be bent or only slightly. need and therefore special Distinguish rigidity.
