Description
Plattenförmiges Trockengleichrichter-Element Bei plattenförmigen Elementen von Trockengleichrichtern, z. B. Kupferoxydgleichrichtern, die beiderseits mit einer den Sitz der Ventilwirkung darstellenden Oxydschicht versehen sind, ist es bekannt, die Stromzuführung zur Oxydschicht durch einen Spritzinetallüberzug zu vermitteln, der zu beiden Seiten der Platte auf die Oxvdschicht aufgebracht wird. Es erübrigt sich dadurch die Anordnung plattenförmiger Gegenelektroden, die unter Vermittlung einer Zwischenlage aus Bleifolie o. dgl. gegen die Oxvdschicht angepreßt werden. Zur leitenden Verbindung der beiderseitigen Spritzmetallüberzüge miteinander und mit der Wechselstromquelle dienten bei der vorerwähnten Einrichtung am Plattenrande angeordnete Blech- oder Drahtklaminern; der Gleichstrom wurde, beispielsweise an einer Durchbohrung der Platte, unmittelbar vom Mutterkupfer abgenommen.Plate-shaped dry rectifier element For plate-shaped elements of dry rectifiers, e.g. B. copper oxide rectifiers, both sides with a the seat of the valve action is provided with an oxide layer, it is known to convey the power supply to the oxide layer through a spray metal coating, which is applied to the oxide layer on both sides of the plate. There is no need thereby the arrangement of plate-shaped counter-electrodes, which under mediation an intermediate layer of lead foil or the like. Be pressed against the oxide layer. For the conductive connection of the two-sided spray metal coatings with each other and with the alternating current source were used in the above-mentioned device on the edge of the plate arranged sheet metal or wire staples; the direct current was on, for example a perforation in the plate, taken directly from the mother copper.
Gemäß der Erfindung können nun die Blech- oder Drahtklammern oder sonstige stromleitende Verbindungsglieder wegfallen und trotzdem beide Plattenseiten für die Gleichrichterwirkung ausgenutzt werden. Dies geschieht dadurch, daß am Rande der Platte zwischen den Oxydschichten und dein die Plattenkante umfassenden Spritzmetallüberzug eine elektrisch isolierende Zwischenschicht so angeordnet ist, daß sie den Plattenrand und die benachbarten Zonen der Plattenseiten bedeckt. Stellt man die isolierende Zwischenschicht durch Auftragen von Zellonlack auf die Oxydschicht her, so erhält man als vorteilhafte Nebenwirkung eine Verbesserung der Haftfestigkeit des Spritzmetalles auf der darunterliegenden Metalloxydschicht.According to the invention, the sheet metal or wire clips or no other electrically conductive connecting elements and still both sides of the plate can be used for the rectifier effect. This is done by being on the edge the plate between the oxide layers and the spray metal coating surrounding the edge of the plate an electrically insulating intermediate layer is arranged so that it is the edge of the plate and covers the adjacent zones of the plate sides. If you put the isolating Interlayer is obtained by applying Zellon lacquer to the oxide layer one advantageous side effect is an improvement in the adhesive strength of the spray metal on the underlying metal oxide layer.
Als Ergebnis einer großen Reihe von Versuchen hat sich herausgestellt, daß zur Herstellung der isolierenden Zwischenschicht gerade Zellonlack in ganz hervorragendem Maße geeignet ist. Hierzu trägt außer der hohen dielektrischen Durchschlagsfestigkeit, welche diesem Lack eigen ist, der Umstand bei, daß er wie kein anderer befähigt ist, die Haftfestigkeit des Spritzmetallüberzuges auf den darunterliegenden Oxy dschichten zu erhöhen.As a result of a large number of experiments, it has been found that for the production of the insulating intermediate layer just Zellonlack in very excellent Dimensions is suitable. In addition to the high dielectric strength, which is peculiar to this lacquer, the fact that it enables like no other is the adhesive strength of the spray metal coating on the underlying oxy to increase layers.
Die Anordnung einer Zellonschicht ist bei Trockengleichrichtern an sich bekannt. Eine derartige Schicht dient bei der bekannten Einrichtung jedoch- lediglich dem Zweck, den Trockengleichrichter gegen äußere Einwirkungen, insbesondere gegen die Einflüsse der atmosphärischen Feuchtigkeit zu schützen.The arrangement of a cellular layer is on with dry rectifiers known. Such a layer is used in the known device, however- only for the purpose of protecting the dry rectifier against external influences, in particular to protect against the influences of atmospheric moisture.
Die Stromzuleitung zu dem Spritzmetallüber7ug kann durch einen mit dem Metallüberzug durch Lötung oder auf andere Weise verbundenen Kupferdraht bewirkt werden.The power line to the spray metal cover can be connected through a the metal coating by soldering or otherwise connected copper wire will.
