- the cover 9 as well as the bellows 7 are welded by furnace brazing to the flange 4 coaxially with the rod 5.
- the bushing 10 is fitted into the rod 5 and snapped into the hood 9 by crossing the orifice of the flange 4.
- the rod 5 can then slide inside the bushing 10 so as to move the movable contact 5 'in axial translation during an operation of the circuit breaker.
- FIG. 2 shows in more detail the tubular metal cover 9.

- FIG. 3 shows in more detail the tubular insulating bushing 10.
- This is preferably made of an injected plastic. It comprises a first cylindrical tubular part 10A whose outside diameter is adjusted with the inside diameter of the cover 9 and which is intended to be inserted coaxially inside the metal cover 9, as well as a second cylindrical tubular part 10B coaxial to part 10A, of smaller diameter and greater length. These two tubular parts are connected together by a third tubular part 10J in an area forming the base of the crossing. This tubular part 10J is shorter longitudinally than the first tubular part 10A, so as to provide an annular space 10L between the first and second parts.
- Part 10B is intended to be inserted coaxially in the orifice 9D delimited by the flange 9A of the cover and in the orifice 11 formed in the flange 4 of the vacuum interrupter.
- the shoulder 10C between the tubular parts 10A and 10B formed by the end of the cylindrical part 10A is intended to come to bear on the inner surface of the flange 9A of the cover 9 when the bushing is inserted in the cover.
- the tubular part 10A has elastic tabs 10D on its cylindrical outer periphery, preferably distributed equidistantly.
- Each tongue extends axially in alignment with the openings 9B of the cover and carries at its free end a lip which projects radially and which is intended to snap into a light 9B of the cover 9 when the bushing 10 is inserted coaxially in the cover 9.
- This snap-fitting of the tabs 10D into the slots 9B thus ensures immobilization in the axial direction A of the passage 10 in the cover 9.
- the snap-fitting of the tabs 10D into the slots 9B can be carried out without mechanical force on the cover 9 thanks to a chamfering of the lip of the tongues.

- the crossing 10 of the bearing is shown in partial projection.
- the metal sealing bellows 7 has one end which ends in a tubular part which passes through the orifice 11 formed in the flange 4 as well as the opening of the cover 9 of the bearing.
- the cover 9 and the bellows 7 are welded to the flange 4 by brazing in the oven, preferably in a single pass after the last vacuum brazing operation in the oven. Furthermore, during this single pass, the bellows 7 is advantageously welded to the inner edge of the orifice of the cover 9.
- the end bellows 7 is inserted into the opening in the cover 9 to protrude below the inner flange of said cover. This makes it possible to visually verify that the bellows is well inserted in the orifice 11 of the flange 4, after the last brazing operation in the oven.
- the annular space 10L of the crossing 10 is arranged so that the end of the bellows 7 can be housed in said space without pressing against the crossing 10 after the snap-fastening thereof.

Abstract
Description
Avec cette fixation par encliquetage, on évite les risques de détérioration de l'ampoule à vide d'une part lors du montage du palier de guidage de la tige, d'autre part lors du serrage d'un élément fileté à l'extrémité de la tige extérieure à l'ampoule. En outre, cette construction contribue à réduire le temps de montage de l'ampoule à vide et donc le coût de réalisation d'un disjoncteur à ampoule à vide.
Dans un mode de réalisation préféré de l'ampoule à vide selon l'invention, le capot métallique est fixé accolé contre le flasque à l'extérieur de l'ampoule et présente des lumières accessibles à des moyens de décliquetage destinés à s'insérer dans lesdites lumières pour appuyer sur les languettes élastiques de la traversée tubulaire, afin de pouvoir retirer ladite traversée pour son recyclage.
Au flasque 3 est fixée une tige fixe non représentée portant un contact fixe. L'ampoule à vide 1 comporte un contact mobile 5' porté par une tige métallique 5 qui coulisse de manière étanche à travers l'orifice 11 du flasque 4 grâce à un soufflet métallique 7 monté à l'intérieur de l'enveloppe 2. La tige 5 est guidée en translation suivant la direction axiale A par un palier 8 constitué par un capot métallique tubulaire 9 et par une traversée tubulaire 10 en matière isolante qui est destinée à être insérée coaxialement dans le capot 9 et encliquetée dans celui-ci. Sur la figure 1, les deux éléments 9 et 10 du palier sont montrés seulement en demi-coupe axiale. Le capot 9 ainsi que le soufflet 7 sont soudés par brasage au four au flasque 4 coaxialement à la tige 5. Ensuite, la traversée 10 est emmanchée dans la tige 5 et encliquetée dans le capot 9 en traversant l'orifice du flasque 4. La tige 5 peut alors coulisser à l'intérieur de la traversée 10 de façon à déplacer en translation axiale le contact mobile 5' lors d'une manoeuvre du disjoncteur.
La partie tubulaire 10A présente sur sa périphérie extérieure cylindrique des languettes élastiques 10D réparties de préférence de façon équidistante. Chaque languette s'étend axialement en alignement avec les lumières 9B du capot et porte à son extrémité libre une lèvre qui saille radialement et qui est destinée à venir s'encliqueter dans une lumière 9B du capot 9 quand la traversée 10 est insérée coaxialement dans le capot 9. Cet encliquetage des languettes 10D dans les lumières 9B assure ainsi l'immobilisation selon la direction axiale A de la traversée 10 dans le capot 9. L'encliquetage des languettes 10D dans les lumières 9B peut être réalisé sans effort mécanique sur le capot 9 grâce à un chanfreinage de la lèvre des languettes. Lorsque la lèvre d'une languette 10D est engagée dans une lumière 9B, la languette s'arc-boute contre un bord de la lumière pour résister à un effort d'extraction de la traversée 10 du capot 9. L'arc-boutement des languettes permet de résister aux efforts d'extraction importants qui peuvent se produire dans des cas extrêmes de fonctionnement du disjoncteur comportant une ampoule à vide selon l'invention. Comme expliqué précédemment, il est essentiel dans l'invention que la traversée 10 soit bloquée en rotation par rapport au flasque 4 et donc par rapport au capot 9. Or, les languettes 10D ne permettent pas à elles seules de résister à un couple important qui serait exercé sur la traversée 10 par la tige 5.
Afin de procurer un blocage en rotation efficace, la partie tubulaire 10A comporte également sur sa périphérie extérieure cylindrique des renfoncements 10 E qui sont répartis entre les languettes 10D en alignement avec les bossages 9C du capot, de sorte que les bossages 9C viennent s'encastrer dans les renfoncements 10 E quand la traversée 10 est insérée dans le capot 9. Les bossages 9C et les renfoncements 10 E sont ajustés pour empêcher toute possibilité de rotation relative par rapport à l'axe A de la traversée 10 dans le capot 9, de façon à ne pas détériorer le soufflet métallique 7.
Les parties tubulaires 10A et 10B de la traversée forment préférablement une seule pièce venue de moulage et la partie tubulaire 10B comporte un alésage intérieur 10F dans lequel coulisse la tige 5. L'alésage 10F présente un ou deux méplats 10G consistant en une large rainure longitudinale, avec une autre rainure longitudinale 10H plus profonde qui sert de canal de ventilation comme cela est déjà connu. Le ou les méplats 10G servent à éviter une rotation de la tige 5 dans la traversée.
