et d'un capot 18.Referring to Figures 1 to 6, a low-voltage multi-pole
Le volume interne de la base 14 est subdivisé par des cloisons 20 parallèles en
plusieurs compartiments 22,24,26,28 pour le logement de modules interrupteurs 30
unipolaires disposés côte à côte dans le boítier 12. A droite du compartiment 28 se
trouve un compartiment 32 additionnel pouvant servir à la mise en place d'auxiliaires
électriques de signalisation 33 de la position ouvert ou fermé. La largeur du
compartiment 32 additionnel est inférieure à celle de chaque compartiment
22,24,26,28 des modules interrupteurs 30.The internal volume of the
Les modules interrupteurs 30 unipolaires sont identiques et constituent les différents
pôles de l'interrupteur 10, qui dans l'exemple décrit, est un interrupteur tétrapolaire.
Chaque module interrupteur 30 unipolaire comporte un barreau de commutation 34
individuel rotatif équipé d'un double contact mobile 36 en pont (figure 6) coopérant
avec deux contacts fixes 38,40 opposés (figure 2 et 4) pour créer une double

liaisons 80,82 parallèles faisant saillie de part et d'autre des flasques 70,72, et se
trouvant en contact avec un secteur circulaire 83 des flasques. Les extrémités
supérieures des tiges 80,82 sont positionnées dans des gorges d'entraínement d'un

manoeuvre 86 accessible de l'extérieur.The
Les extrémités inférieures des deux tiges de liaisons 80,82 coopèrent avec deux
surfaces d'appui d'une bague 52 intermédiaire pour déplacer les tringles 58,60 selon
des sens de translation opposés lors du changement d'état de la genouillère 66 opéré
par le pivotement de la poignée de manoeuvre 86 dans le sens de l'ouverture ou de la
fermeture. Un ressort 92,94 de compression est enfilé sur chaque levier 74,76 du
dispositif à genouillère 66 en prenant appui sur la tige de liaison 80,82
correspondante.The lower ends of the two connecting

directement au pignon principal 84 après introduction selon la flèche F1 travers un
orifice 96 du capot 18 (figure 5).During a front control, the
Une commande latérale est également possible en accouplant la poignée de
manoeuvre 86 à un pignon conique 98 selon le sens de la flèche F2. Le mouvement
de rotation du pignon conique 98 est transmis au pignon principal 84 par
l'intermédiaire d'un pignon de renvoi 100. Dans ce cas, l'orifice 96 est libre, et
permet l'adaptation d'un détecteur de position (non représenté) permettant un contrôle
visuel de l'état fermé ou ouvert de l'interrupteur multipolaire 10. Lateral control is also possible by coupling the

barres conductrices 36A,36B parallèles traversant des lumières 102 opposées du
plot 42, en étant séparées l'une de l'autre par un intervalle d prédéterminé (figure 6).
Un ressort 104 de pression de contact est agencé à l'intérieur du plot 42 en s'étendant
perpendiculairement à la barre 36B.The movable
Le double pont de contact 36 de chaque pôle coopère d'un côté avec le premier
contact fixe 38, et du côté opposé avec l'autre contact fixe 40. A chaque paire de
contacts 36,38;36,40 est associée une chambre de coupure 106 à tôles de
désionisation.The
Les deux contacts fixes 38,40 de chaque module interrupteur 30 se prolongent chacun
par une plage de raccordement 108,110 coopérant respectivement avec une cage de
borne de connexion 112,114. La section des barres 36A, 36B constitutives du double

suivant:
En position de fermeture illustrée aux figures 2 et 4, le contact fixe 38,40 de chaque
pôle est inséré entre les pinces des deux barres 36A, 36B du double contact
mobile 36. L'arête d'entrée des contacts fixes 38,40 est avantageusement chanfreinée

La séparation des contacts pour l'ouverture de l'interrupteur s'effectue en faisant
pivoter la poignée de manoeuvre 86 d'un quart de tour. La rotation du pignon
principal 84 provoque un changement d'état du dispositif à double genouillère 66, et
la mise en translation opposée des tringles d'actionnement 58,60 par l'action des
tiges 80,82. Sur la figure 3, la tringle 58 est ainsi déplacée vers la droite, tandis que
l'autre tringle 60 est sollicitée en sens inverse vers la gauche.The separation of the contacts for opening the switch is done by

main 84 causes a change of state of the
Le déplacement en translation selon des sens opposés des deux tringles 58,60
s'effectue en synchronisme, et provoque une rotation simultanée des barreaux de
commutation 34 élémentaires de tous les pôles. La tringle 58 travaille en traction,
alors qu'un effort de poussée est exercé sur la tringle 60 qui travaille en compression
lors de la phase d'ouverture de l'interrupteur. Les contraintes mécaniques sur les
tringles 58,60 sont inversées pendant la phase de fermeture.The displacement in translation in opposite directions of the two rods 58.60
takes place in synchronism, and causes a simultaneous rotation of the bars of
34 elementary switching of all poles. The
Au début de la course d'ouverture, l'arc prenant naissance entre les
contacts 36,38;36,40 est rapidement éteint grâce à la présence des chambres de
coupure 106.At the start of the opening race, the arc between the

Les mêmes éléments standards peuvent être utilisés pour réaliser un interrupteur tripolaire. Les barreaux de commutation 34 sont identiques, il suffit de remplacer les tringles 58,60 par des tringles plus courtes, et de faire usage d'un boítier à trois compartiments unipolaires.The same standard elements can be used to make a switch pole. The switching bars 34 are identical, it suffices to replace the 58.60 rods by shorter rods, and make use of a three box unipolar compartments.
Claims (10)

- The switch according to claim 1 characterized in that the driving means of each elementary switching bar (34) comprise a driving lug (46) arranged at the upper end of the stud (42), and a transmission ring (52) surrounding said lug (46) and having in addition two pins (54,56) inserted in holes (64) arranged in the actuating rods (58,60).
- The switch according to claim 1 or 2 characterized in that the two actuating rods (58,60) work respectively in traction and in compression following the action of the connecting rods (80,82) on one of the rings (52) of an intermediate pole.
- The switch according to claim 3 characterized in that the operating mechanism (62) comprises a double toggle device (66) associated to the two connecting rods (80,82), and a pinion device (68) with front or lateral actuation.
- The switch according to claim 4 characterized in that the double toggle device (66) is composed of two levers (74,76) articulated on one another at the level of the connecting rods (80,82) by means of an intermediate lever (78), of a pair of fixed flanges (70,72) having a circular section (83) along which the two rods (80,82) move, and of a spring (92,94) threaded onto each pivoting lever (74,76) and bearing on the corresponding connecting rod (80,82).
- The switch according to claim 5 characterized in that the connecting rods (80,82) comprise upper ends positioned in gorges of a main pinion (84) of the pinion device (68).
- The switch according to claim 6 characterized in that the main pinion (84) is in mechanical connection with a conical pinion (98) by means of a counterpinion (100) and that a removable operating handle (86) can be fitted either to the main pinion (84) or to the conical pinion (98) to achieve front control or lateral control.
- The switch according to one of the claims 1 to 7 characterized in that the case (12) is formed by superposition of a base (14) housing the compartments (22,24,26,28) of the single-pole modules, an intermediate housing (16) containing the drive means (46,52) of the studs (42) and the actuating rods (58,60), and a cover (18) for positioning of the operating mechanism (62).
- The switch according to one of the claims 1 to 8 characterized in that each switching bar (34) bears a double movable contact (36) arranged as a bridge formed by two parallel conducting bars (36A, 36B) passing through apertures (102) of the insulating stud (42), separated from one another by a preset gap (d) and operating on one side in conjunction with a first stationary contact (38) in connection with one of the connection terminals (112) and on the opposite side with a second stationary contact (40) in connection with the other connection terminal (114) of each pole.
- The switch according to claim 7 characterized in that the case (12) contains an additional compartment (32) for housing at least one electrical indication auxiliary (33) for indication of the open or closed position of the contacts of the switch (10), change of state of the auxiliary (33) taking place at the end of rotation travel of the lateral conical pinion (98) by means of an operating slide (88).
