Description

Elektrischer Drehkondensator für Radioanlagen, dessen Statorbleche durch Schraubbolzen unter Zwischenlegen von Distanzringen, von denen einer mit einem Gewindeschaft versehen ist, zusammengehalten und mittels dieses Schaftes an zwischen Deck- und Grundplatte gelagerten Isolierstücken festgeklemmt sind Die Erfindung betrifft einen elektrischen Drehkondensator für Radioanlagen, dessen Statorbleche durch Schraubbolzen unter Zwischenlegen von Distanzringen, von denen einer mit einem Gewindeschaft versehen ist, zusammengehalten und mittels dieses Schaftes an zwischen Deck- und Grundplatte gelagerten Isolierstücken festgeklemmt sind.Electrical variable capacitor for radio systems, its stator laminations by screw bolts with spacer rings in between, one of which with a Threaded shaft is provided, held together and by means of this shaft on between Top and base plate mounted insulating pieces are clamped The invention relates to an electrical variable capacitor for radio systems, its stator laminations by screw bolts with spacer rings in between, one of which with a Threaded shaft is provided, held together and by means of this shaft on between Top and base plate mounted insulating pieces are clamped.

Bei bekannten Drehkondensatoren dieser Art ist der Schaft der Distanzringe als Klemmring ausgebildet, der das zwischen Deck- und Grundplatte gelagerte, im Querschnitt zylindrische Isolierstück umfaßt. Nachteilig hierbei ist, daß für die Lagerung der Statorbleche mindestens drei Isolierstücke vorhanden sein müssen, um eine gegenseitige Verlagerung der Statorbleche mit Sicherheit zu vermeiden. Ein weiterer Nachteil besteht darin, daß unnötig viel Schrauben "zum Be- festigen der Klemmringe benötigt werden. Dies hat eine umständliche und zeitraubende Montage zur Folge und verteuert die Herstellung solcher Drehkondensatoren unnötig.In known rotary capacitors of this type, the shaft of the spacer rings is designed as a clamping ring which encompasses the insulating piece, which is mounted between the cover plate and the base plate and has a cylindrical cross-section. The disadvantage here is that at least three insulating pieces must be present for the mounting of the stator laminations in order to reliably avoid mutual displacement of the stator laminations. A further disadvantage is that unnecessarily much screws "for loading the clamping rings are needed to consolidate. This results in a cumbersome and time-consuming mounting result and increases the cost of manufacture of such variable capacitors unnecessary.

Gemäß vorliegender Erfindung werden die genannten Nachteile dadurch vermieden, daß nur zwei Isolierstücke vorhanden sind, welche je eine Nut aufweisen, in der die Statorbleche unmittelbar gelagert sind. Der Vorteil dieser Bauart besteht darin, daß nur zwei in der Deck- und Grundplatte des Kondensators angeordnete Isolierstücke notwendig sind, um ein Verlagern der Statorbleche mit Sicherheit zu verhüten, wodurch einfachste Handhabung beim Zusammenbau des Drehkondensators gemäß der Erfindung, Materialersparnis und damit billigste Herstellungskosten gegeben sind. Dies ist darauf zurückzuführen, daß die Statorbleche in der Nut der Isolierstücke gelagert sind, wodurch letztere, ohne Anwendung besonderer Sicherungsmaßnahmen, sich in der Deck- und Grundplatte nicht drehen können. Die Isclierstücke besitzen ein Langloch, durch welches ein mit den Statorblechen in leitender Verbindung stehender Schaft hindurchgeführt ist, der zum Einstellen und Festklemmen der Statorbleche dient und gleichzeitig zum Anschluß der stromführenden Leitung benutzt werden kann. Auf der Zeichnung ist der Drehkondensator gemäß der Erfindung an einem Ausführungsbeispiel dargestellt.According to the present invention, the disadvantages mentioned are thereby eliminated avoided that only two insulating pieces are present, each of which has a groove, in which the stator laminations are stored directly. The advantage of this type of construction is there in that only two insulating pieces arranged in the top and base plate of the capacitor are necessary to prevent displacement of the stator laminations with security, whereby easiest handling when assembling the rotary capacitor according to the invention, Material savings and thus the cheapest manufacturing costs are given. This is due to the fact that the stator laminations are stored in the groove of the insulating pieces are, whereby the latter, without the application of special security measures, are in the The top and base plate cannot rotate. The Isclier pieces have an elongated hole, through which a shaft that is in conductive connection with the stator laminations is passed, which is used to adjust and clamp the stator laminations and can be used at the same time to connect the live line. On the The drawing is the variable capacitor according to the invention in one embodiment shown.

Abb. 2 ist ein Grundriß der Abb. i in teilweisem Schnitt.Figure 2 is a partially sectioned plan view of Figure i.

Der Drehkondensator besteht aus einer Deckplatte i und einer Grundplatte 2, die durch Distanzbolzen 3 miteinander verbunden sind. Die Statorbleche 4 sind in bekannter Weise durch einen Schraubbolzen 6 zusammengehalten. Ein Distanzring 7 ist mit einem Gewindeschaft 8 versehen, der ein aus Isoliermaterial bestehendes Distanzstück 9 durchdringt und durch eine Mutter 15 an diesem befestigt wird: Erfindungsgemäß sind nur zwei Isolierstücke 9 vorhanden, welche je eine Nut io aufweisen, in- der die freien Enden i i sämtlicher Statorbleche 7 gelagert sind. Die Nut io ist so äusgebildet, daß sie zuverlässig ein Drehen des Isolierstückes 9 in den Platten i, 2 und dad;irch ein gegenseitiges Verlagern der Statorbleche verhindert. Im Ausführungsbeispiel ist die Nut io rechteckig gestaltet. Sie kann aber auch beliebig anderen Querschnitt haben, der diesen Anforderungen entspricht. Die Durchbrechung 12 für den Gewindeschaft 8 ist als Langloch ausgebildet, um die Statorbleche gegen die Rotorbleche nach Zusammenbau des Kondensators einstellen zu können. Der Gewindeschaft 8 dient gleichzeitig zum Festklemmen der stromführenden Leitungen 13, 14.The variable capacitor consists of a cover plate i and a base plate 2, which are connected to one another by spacer bolts 3. The stator laminations 4 are Held together in a known manner by a screw bolt 6. A spacer ring 7 is provided with a threaded shaft 8, which consists of an insulating material Spacer 9 penetrates and is fastened to this by a nut 15: According to the invention there are only two insulating pieces 9, each of which has a groove io the free ends i i of all stator laminations 7 are supported. The groove is like this äusgebilden that they reliably rotate the insulating piece 9 in the plates i, 2 and dad; irch prevents mutual displacement of the stator laminations. In the exemplary embodiment the groove io is designed to be rectangular. But it can also have any other cross-section that meets these requirements. The opening 12 for the threaded shaft 8 is designed as an elongated hole to the stator laminations against the rotor laminations after assembly to adjust the capacitor. The threaded shaft 8 is also used to Clamping the current-carrying lines 13, 14.
