On décrira maintenant en se référant à la figure 4 une forme particulièrement intéressante de réalisation de la pièce assurant la liaison électrique entre la source de très haute tension et la broche reliée à la grille G3 du tube cathodique.We will now describe with reference to Figure 4 a particularly interesting embodiment of the part ensuring the electrical connection between the very high voltage source and the pin connected to the grid G3 of the cathode ray tube.

Sur cette figure, tous les éléments identiques à ceux qui sont représentés sur la figure 1 portent les mêmes références affectées de l'indice 2.In this figure, all the elements identical to those which are represented in FIG. 1 have the same references assigned with the index 2.

Suivant ce mode de réalisation, au moyen de contact 5 représenté figure 1 est substitué l'ensemble 30-31. La référence 30 désigne une partie tubulaire cylindrique intégrante du connecteur de très haute tension, donc en matière isolante. Elle inclut le moyen de contact 31 en matériau conducteur. Ce moyen 31 est luimême tubulaire, favorablement en forme connue dite de "tulipe"; il est prévu pour recevoir la broche du tube cathodique reliée à la grille G3.According to this embodiment, the contact 30 shown in FIG. 1 is replaced by the assembly 30-31. The reference 30 designates a cylindrical tubular part integral with the very high voltage connector, therefore made of insulating material. It includes the contact means 31 made of conductive material. This means 31 is itself tubular, favorably in known form called "tulip"; it is designed to receive the pin of the cathode ray tube connected to the grid G3.

La référence 33 désigne les éléments de contact reliés aux éclateurs moyenne tension non visibles sur cette figure et tels que représentés sur la figure 1 du brevet français FR-A-2 452 189.The reference 33 designates the contact elements connected to the medium-voltage spark gaps not visible in this figure and as shown in Figure 1 of French patent FR-A-2 452 189.

L'élément 30 est prévu, ainsi qu'il est précisé par le traits mixtes, pour pénétrer dans le logement tubulaire 34 (non fermé dans cet exemple), ménagé dans le support 32.The element 30 is provided, as indicated by the dashed lines, to enter the tubular housing 34 (not closed in this example), formed in the support 32.

Cette disposition est particulièrement avantageuse, car elle permet de disposer l'ensemble connecteur suivant les positions relatives angulaires les plus favorables en fonction de l'emplacement disponible sur la plaquette de connexion supportant le dit ensemble connecteur. Elle permet également l'interchangéabilité de cet ensemble connecteur avec d'autres supports de tube ayant une implantation différente.This arrangement is particularly advantageous because it makes it possible to arrange the connector assembly according to the most favorable angular relative positions as a function of the location available on the connection plate supporting said connector assembly. It also allows the interchangeability of this connector assembly with other tube supports having a different layout.

Il est entendu que sans sortir du cadre de l'invention des variantes pourront être apportés concernant la forme et les dimensions les éléments constitutifs. On citera dans cet ordre d'idée que le logement 34 prévu dans le support de tube 32 pourrait être un cylindre à paroi continue et non ouverte.It is understood that without departing from the scope of the invention, variants may be made concerning the shape and the dimensions of the constituent elements. In this connection, it will be mentioned that the housing 34 provided in the tube support 32 could be a cylinder with a continuous wall and not open.
