Description
Die Erfindung betrifft eine metallene Entladungsröhre für sehr kurze Wellen, bei der eine Schutzkappe eine oder mehrere mittels Glaszwischenstücke in die Wand eingeschmolzene Zuleitungen umgibt. Die Zuleitungen sind hierbei durch verhältnismäßig bewegliche Leiter mit Anschlußkontakten auf der Schutzkappe verbunden. Die Schutzkappe,_die gewöhnlich die Form eines stumpfen Kegels mit etwas ovalem Querschnitt hat, soll die leicht zerbrechlichen Einschmelzungen in mechanischer Hinsicht schützen.The invention relates to a metal discharge tube for very short Waves in which a protective cap has one or more glass spacers in the wall surrounds melted supply lines. The leads are through relatively movable conductors connected to terminal contacts on the protective cap. The protective cap, which usually has the shape of a truncated cone with something oval Has cross-section, intended to be easily fragile in mechanical meltdown Respect.
Es hat sich gezeigt, daß, besonders wenn zwischen der Zuleitung und der metallenen Röhrenwand Impulsspannungen mit steiler Front liegen, Funken von den Zuführungsleitungen nach den Seitenwänden der Glasschutzkappe auftreten. Diese Funken können zur Zerstörung der Zuführungsleitungen, zu Verlusten und zur Störung im Röhrenbetrieb führen.It has been shown that, especially if between the supply line and the metal tube wall are impulse voltages with a steep front, sparks from the supply lines occur after the side walls of the protective glass cap. These Sparks can destroy the supply lines, lead to losses and malfunctions lead in tube operation.
Bei einer metallenen Entladungsröhre für sehr kurze Wellen, bei der eine Glasschutzkappe eine oder mehrere in die Wand der Röhre eingeschmolzene Zuführungsleitungen umgibt, die durch bewegliche Verbindungen mit Anschlußkontakten auf der Schutzkappe verbunden sind, sind erfindungsgemäß eine oder mehrere Leiter in Form kleiner Federn zwischen den Zuführungsleitungen und der Innenfläche der Kanten der Schutzkappe derart angebracht, daß sie eine mechanische Verbindung mit ihr herstellen.In the case of a metal discharge tube for very short waves, in which a protective glass cap one or more feed lines fused into the wall of the tube surrounds that by movable connections with connection contacts on the protective cap are connected are, according to the invention, one or more conductors in the form of small springs between the feed lines and the inner surface of the edges of the protective cap mounted so that they establish a mechanical connection with her.
Auf diese Weise kann das Funkensprühen nach der Schutzkappe auch bei sehr steilen Spannungsimpulsen zwischen den Zuführungsleitungen und der metallenen Röhrenwand ganz unterdrückt werden. Im Röhrenbau sind feuernde Lagerungen von Elektroden und Elektrodenhalterungen bekannt.In this way, the spark can also be sprayed after the protective cap very steep voltage pulses between the supply lines and the metal ones Tube wall are completely suppressed. In tube construction there are firing bearings for electrodes and electrode holders are known.
Die Erfindung ist in der Zeichnung näher erläutert, in der die Fig. i und 2 zwei Querschnitte durch eine Entladungsröhre mit Schutzkappe darstellen, die mit Antisprühmitteln nach der Erfindung versehen ist. i bezeichnet die metallene Röhrenwand, 2 die ovale Schutzkappe aus hartem Glas, 3 bezeichnet zwei Glühkathodenzuleitungen, die mittels gläserner Röhrchen 4 mit der Wand i verschmolzen sind. Bewegliche Drähte 5 führen nach Anschlußkontakten 6 in der ebenen, oberen Seite 7 der Schutzkappe. An einer jeden der Zuführungsleitungen ist eine kleine Metallfeder 8 befestigt; die an die Schutzkappe 2 andrückt. Die Kühlrippen der Metallröhre sind mit 9 bezeichnet.The invention is explained in more detail in the drawing, in which FIG. i and 2 represent two cross-sections through a discharge tube with protective cap, which is provided with anti-spray agents according to the invention. i denotes the metallic one Tube wall, 2 the oval protective cap made of hard glass, 3 denotes two hot cathode supply lines, which are fused to the wall i by means of glass tubes 4. Movable wires 5 lead to connection contacts 6 in the flat, upper side 7 of the protective cap. A small metal spring 8 is attached to each of the supply lines; which presses against the protective cap 2. The cooling fins of the metal tube are denoted by 9.
