Description
Metallgehäuse für Drehkondensatoren Durch die fortschreitende technische Entwicklung der Nachrichten- und Steuerungstechnik der letzten 10 Jahre war es notwendig geworden, dem Drehkondensator eine wesentlich gedrängtere Bauform zu geben. Dadurch stieg aber die Empfindlichkeit der Plattensysteme gegen Verstimmungen, die insbesondere bei der Halterung des Kondensators auftreten, so daß an das die Plattensysteme umgebende Gehäuse zwangläufig erhöhte Anforderungen gestellt werden mußten.Metal housing for variable capacitors Due to the advancing technical It was necessary to develop communications and control technology over the past 10 years has become to give the variable capacitor a much more compact design. Through this but increased the sensitivity of the disk systems to upsets, in particular occur when holding the capacitor, so that to the surrounding plate systems Housing inevitably increased requirements had to be made.
Der nunmehr verhältnismäßig sehr kritisch gewordenen V erwindungsfestigkeit des Drehkondensatorgehäuseswurde zunächst einmal nicht ohne Erfolg mit einem dickwandigen und mit hohen Seitenwänden ausgestatteten Gehäuse begegnet. Dieses aus Spritzguß bestehende Gehäuse mußte jedoch erfahrungsgemäß infolge eines zu hohen Ausdehnungskoeffizienten einem beschränkten Verwendungszweck vorbehalten bleiben.The resistance to twisting, which has now become relatively very critical The rotary capacitor case was initially not without success with a thick-walled one and housings equipped with high side walls. This made of injection molding However, experience has shown that existing housings had to be due to an excessively high coefficient of expansion reserved for a limited purpose.
Weitere aus Stahlblech gezogene Wannen wurden bald durch Boden- und Ziehrandverformungen, zum Teil sogar durch Anbringung von Kerben in den Ecken mehr versteift. Sie wurden abgelöst durch die heute weithin verbreitete Bauart eines Gehäuses, das aus gestanzten, zum Teil glatten oder verformten Einzelteilen zusammengesetzt und dann vernietet oder verschweißt wird.Further tubs made of sheet steel were soon replaced by floor and Deformations of the drawing edge, in some cases even more by making notches in the corners stiffened. They were superseded by the design of a, which is widespread today Housing composed of stamped, partly smooth or deformed individual parts and then riveted or welded.
Sehr nachteilig können sich hier schlechte Niet-oder Schweißstellen auswirken, da sie Anlaß zu Funktionsstörungen geben.Bad rivets or welds can be very disadvantageous here as they give rise to malfunctions.
Diese Nachteile werden bei einem Metallgehäuse für Drehkondensatoren, das als v erwindungssteife Wanne mit einer Wandstärke von 1 bis 2 mm in einem Stück gezogen oder gespritzt ist, in der Weise vermieden, daß erfindungsgemäß die vier Ecken der Wanne im mittleren Bereich zwischen Ober- und Unterseite mit senkrecht stehenden und stumpfwinklig an die anliegenden Flächen anstoßenden flächenförmigen Einbuchtungen versehen sind. Dadurch erhält das Drehkondensatorgehäuse eine außergewöhnlich hohe Verwindungsfestigkeit, durch die das Plattensystem 2 und 3 gegen Verstimmungen weitgehend geschützt wird.These disadvantages are in a metal housing for variable capacitors, as a torsion-resistant tub with a wall thickness of 1 to 2 mm in one piece is drawn or injected, avoided in such a way that according to the invention the four Corners of the tub in the middle area between the top and bottom with vertical standing and flat-shaped adjoining the adjacent surfaces at an obtuse angle Indentations are provided. This gives the rotary capacitor housing an exceptional one high torsional stiffness, which makes the plate system 2 and 3 against detuning is largely protected.
In der Zeichnung ist ein Ausführungsbeispiel eines Metallgehäuses für Drehkondensatoren nach der Erfindung dargestellt. In dem durch Spritzguß mit einer Wandstärke von 1 bis 2 mm aus einem Nichteisenmetall in Form einer Wanne hergestellten Metallgehäuse 1 sind Stator 2 und Rotor 3 untergebracht. An den vier Ecken ist die Wanne 1 mit den flächenförmigen Einbuchtungen 4 versehen.In the drawing is an embodiment of a metal housing shown for rotary capacitors according to the invention. In which by injection molding with a wall thickness of 1 to 2 mm made of a non-ferrous metal in the form of a tub Metal housing 1 houses the stator 2 and rotor 3. At the four corners is that The tub 1 is provided with the flat indentations 4.
