Description
Bei der Herstellung elektrischer Entladungsröhren liegt häufig die Aufgabe vor, mehrere Elektroden in bestimmter Lage relativ zueinander zu fixieren. Das ist beispielsweise der Fall, wenn man mehrere Gitter mit ihren Windungen zur Deckung bringen will, um zu erreichen, daß bestimmte Gitter einer Elektronenröhre gegen die primären Elektronen abgeschirmt werden. Hierbei ist es erforderlich, die Gitterstege an ganz bestimmten Stellen zu haltern, die vom Anfang der Windung bzw. von einer beliebigen Bezugswindung einen bestimmten Abstand haben.In the manufacture of electric discharge tubes, the task is often to have several electrodes in to fix a certain position relative to each other. This is the case, for example, when you have multiple grids wants to bring their turns to coincide in order to achieve that certain grid of an electron tube be shielded from the primary electrons. Here it is necessary to use the lattice bars to be held at very specific points, from the beginning of the turn or from any reference turn have a certain distance.
Man hat für die Fixierung von mehreren sich deckend gewickelten Gittern die Stege bereits mit Anschlägen versehen, z. B. einen Span angehoben, um damit nach dem Einsetzen der Stege in die Öffnungen einer zur Halterung dienenden Isolierscheibe die gewünschte Lage der Gitter zu erzwingen.You already have the bars for the fixation of several congruently wound grids Provided stops, z. B. raised a chip so that after the insertion of the webs into the openings to force an insulating washer used for holding the desired position of the grid.
Derartige Anordnungen gestatten aber nicht für alle Fälle eine ausreichend genaue Fixierung der Elektroden, bei ihnen müssen außerdem in genau vorgegebenem Abstand voneinander jeweils zwei Anschläge angeordnet werden, um Verschiebungen der Elektroden in axialer Richtung sicher auszuschließen.Such arrangements do not allow a sufficiently precise fixation of the in all cases Electrodes, they must also have two stops at a precisely specified distance from each other be arranged in order to safely exclude displacements of the electrodes in the axial direction.
Demgegenüber ist es durch die Erfindung möglich, eine sehr genaue Fixierung der Elektroden zu erreichen und die Montage solcher Röhren zu vereinfachen. In contrast, the invention makes it possible to achieve a very precise fixation of the electrodes and to simplify the assembly of such tubes.
Gemäß der Erfindung dienen zu diesem Zweck bei einer elektrischen Entladungsröhre, bei welcher eine oder mehrere Elektroden, beispielsweise mehrere sich deckend gewickelte Gitter, zwecks Fixierung in ihrer Lage mit Anschlägen versehen sind, als Anschläge Einkerbungen, in welche Fixierfedern eingreifen.According to the invention are used for this purpose in an electrical discharge tube in which a or several electrodes, for example several congruently wound grids, for the purpose of fixing in their Position are provided with stops, notches as stops, in which locking springs engage.
Die Fixierfedern können zwischen zwei Isolierscheiben, vorzugsweise zwei Glimmerscheiben, gehalten werden. Es ist aber auch möglich, die Fixierfedern mit einer Isolierscheibe fest zu verbinden, etwa durch die Anordnung von Ansätzen an den Federn, mittels deren eine Befestigung zwischen Feder und Isolierscheibe durch Festklemmen mög-Hch ist.The fixing springs can be held between two insulating disks, preferably two mica disks will. But it is also possible to firmly connect the fixing springs with an insulating washer, for example by the arrangement of approaches on the springs, by means of which an attachment between Spring and insulating washer are possible by clamping.
In der Zeichnung sind Ausführungsbeispiele nach der Erfindung dargestellt.In the drawing, exemplary embodiments according to the invention are shown.
Die Fig. 1 zeigt teilweise ein Einzelgitter mit den Stegen 1 und 2, welche die Gitterwindung 3 tragen. In einem bestimmten Abstand vom Anfang der Gitterwindungen oder von einer beliebigen Bezugswindung sind Einkerbungen vorgesehen, in welche die Fixierfeder 4 eingreift. Zu beiden Seiten der Feder 4 sind Glimmerscheiben 5 und 6 angeordnet, Elektrische Entladungsröhre1 partially shows a single grid with the webs 1 and 2 which carry the grid winding 3. At a certain distance from the start of the grid turns or from any reference turn, notches are provided in which the fixing spring 4 engages. Mica washers 5 and 6 are arranged on both sides of the spring 4, Electric discharge tube

Die Fig. 2, in der die einzelnen Teile mit den gleichen Bezugszeichen wie in Fig. 1 versehen sind, zeigt eine Ansicht des Einzelgitters nach Fig. 1 von unten her, nachdem die Klemmglimmerscheibe 6 abgenommen worden ist.Fig. 2, in which the individual parts are provided with the same reference numerals as in Fig. 1, shows a view of the individual grating according to FIG. 1 from below, after the clamping mica disk 6 has been removed has been.
In Fig. 3 sind zwei sich deckend gewickelte Gitter dargestellt, zu deren Fixierung je eine Feder 4 und 4α dient. In diesem Falle sind die Federn 4, 4 α mit einer Glimmerscheibe 5 dadurch fest verbunden, daß die Ansätze 7 der Federn 4, 4 a durch entsprechende Öffnungen der Glimmerscheibe 5 gesteckt und dann umgebogen werden.In Fig. 3, two congruently wound grids are shown, for their fixation each a spring 4 and 4α serves. In this case, the springs 4, 4 α are firmly connected to a mica washer 5 in that the lugs 7 of the springs 4, 4 a inserted through corresponding openings in the mica disk 5 and then be bent.
