Description
Redresseur métallique. Le brevet. principal a. pour objet. un redres seur métallique, caractérisé en ce qu'il coin- prend un ensemble d'éléments redresseurs constitués et assemblés de telle façon qu'une pression est, appliquée à chaque élément en une partie où la -contre-électrode n'est pas en contact avec l'électrode active.
La présente invention concerne. aine modi fication du redresseur métallique du type dé crit dans le brevet principal qui permet d'ob tenir les mêmes résultats. Suivant l'invention, l'électrode active de chaque élément est en partie isolée de sa. base métallique de telle manière que lorsqu'une pression est appliquée à l'élément, la pression exercée à travers la contre-électrode sur l'électrode active de l'élément soit confinée à la portion de celle.ci qui est isolée de sa base métallique.
Le dessin annexé montre, à titre d'exem ple, deus formes d'exécution de l'objet de l'invention.
Dans le dessin, la fig. 1 montre une vile en coupe d'un élément. redresseur monté sir un axe isolant, et. la fi-. 2 une vite en coupe d'une antre forme d'élément redresseur dis- posé pour être monté dans un tube isolant comme représenté par exemple à la fig. 3 du brevet. principal.
A la fig. 1, 1 indique la base métallique, par exemple Lui disque en fer ou d'autre mé- tal convenable, et \? une couche semi=conduc- tive de sélénium formant. l'électrode active. Précédemment à l'application de cette couche une rondelle 3 de matière isolante est appli quée à la base métallique afin de couvrir une partie de la base. La surface libre :du sélé nium est recouverte par projection de métal pour former la contre-électrode 4.
Gomme représenté dans la fi-Y. 1 une ron delle de serrage 5 en métal peut être pressée fermement contre le métal @de la contre-élec- trode 4, l'élément étant monté, comme indiqué dans la fig. 1 en lignes pointillées, avec un ou plusieurs éléments semblables sur un axe isolé 6. Il est évident qu'aucune pression n'est exercée sur la partie efficace de l'élé ment.
La présente invention peut être appliquée à différentes .dimensions et formes de redres seurs, mais elle est :d'importance particulière en ce qui concerne ,les petits redresseurs du type montrés dans la fig. 2, dans lesquels les éléments peuvent être assemblés clans un tube isolant.. Dans cette forme d'exécution iui an neau isolant. 3 est placé sur la base métal lique, cet anneau limitant la.
surface effi cace de ,l'élément. Ainsi la portion efficace du redresseur se trouve au centre de l'élément et n'est pas affectée par la pression lorsque les éléments sont assemblés puisque la pression est confinée à la portion couverte par le ma tériel isolant.
Metal rectifier. The patent. principal a. for purpose. a metal rectifier, characterized in that it wedges a set of rectifying elements constituted and assembled in such a way that a pressure is applied to each element in a part where the counter-electrode is not in contact with the active electrode.
The present invention relates to. aine modification of the metal rectifier of the type described in the main patent which makes it possible to obtain the same results. According to the invention, the active electrode of each element is partly isolated from its. metal base such that when pressure is applied to the element, the pressure exerted through the counter electrode on the active electrode of the element is confined to the portion thereof which is isolated from its base metallic.
The accompanying drawing shows, by way of example, two embodiments of the object of the invention.
In the drawing, fig. 1 shows a sectional city of an element. rectifier mounted on an insulating shaft, and. the fi-. 2 a quick sectional view of another form of a rectifying element arranged to be mounted in an insulating tube as shown for example in FIG. 3 of the patent. main.
In fig. 1, 1 indicates the metallic base, for example Him disc of iron or other suitable metal, and \? a semi = conductive layer of selenium forming. the active electrode. Prior to the application of this layer, a washer 3 of insulating material is applied to the metal base in order to cover part of the base. The free surface: selenium is covered by projection of metal to form the counter-electrode 4.
Eraser represented in the fi-Y. 1 a metal washer 5 can be pressed firmly against the metal @ of the counterelectrode 4 with the element mounted, as shown in fig. 1 in dotted lines, with one or more similar elements on an isolated axis 6. It is obvious that no pressure is exerted on the effective part of the element.
The present invention can be applied to different sizes and shapes of straighteners, but it is of particular importance with regard to small straighteners of the type shown in FIG. 2, in which the elements can be assembled in an insulating tube. In this embodiment iui an insulating ring. 3 is placed on the metal base, this ring limiting the.
effective surface of the element. Thus the effective portion of the rectifier is in the center of the element and is not affected by pressure when the elements are assembled since the pressure is confined to the portion covered by the insulating material.
