Sur la figure 1, on voit un disjoncteur D en boítier moulé présentant une
configuration tétrapolaire et destiné à être utilisé dans une application domestique
ou industrielle. Ce boítier B comporte, sur chacune de ses deux grandes faces
opposées (dont seulement une 1 est visible sur cette figure) quatre compartiments
de borne 2, 3, 4, 5. Les quatre compartiments prévus sur la face du disjoncteur D
non représentée sur cette figure, logent respectivement les quatre barrettes de
réseau du disjoncteur, tandis que les quatre compartiments 2 à 5 prévus sur la face
représentée 1 du disjoncteur D logent respectivement les quatre barrettes de charge
6 à 9.In Figure 1, we see a circuit breaker D in molded housing having a
4-pole configuration and intended for use in a domestic application
or industrial. This case B has, on each of its two large faces
opposite (of which only 1 is visible in this figure) four
La connexion des barrettes de charge 6 à 9 avec les circuits électriques externes à protéger, est le plus couramment réalisée au moyen de bornes de charges, de même que la connexion des barrettes de réseau aux câbles du réseau est réalisée par l'intermédiaire de bornes de réseau, lesdites bornes étant montées dans les compartiments correspondants sur les lieux d'installation.The connection of charge bars 6 to 9 with the external electrical circuits to protect, is most commonly achieved by means of charging terminals, even that the connection of the network modules to the network cables is carried out via network terminals, said terminals being mounted in the corresponding compartments at the installation site.
Ainsi, on voit sur la figure 1, que les compartiments de charge 2 à 5 sont équipés de
bornes de charge 10 à 13. Chaque borne de charge 10 à 13 est constituée par un
bloc de métal 14 de forme générale sensiblement parallélépipédique traversé par un
passage allongé 15 à l'intérieur duquel s'étend l'une des plages de contact 6 à 9 du
disjoncteur D. La forme de chaque compartiment 2 à 5 correspond sensiblement à la
forme extérieure du bloc 14 de manière que chaque bloc 14 soit immobilisé
verticalement après introduction dans le compartiment 2 à 5. On voit également sur
cette figure, que chaque compartiment 2 à 5 comporte d'une part, au niveau de ses
deux faces latérales opposées 2a, 2b, deux rainures supplémentaires 16, 17
destinées à faciliter le retrait de la borne (par exemple au moyen d'un outil) et
d'autre part, à sa partie inférieure, deux rainures supplémentaires 18, 19 destinées à
recevoir un écrou à oreille 20 comme ceci sera décrit ultérieurement. Chaque bloc
14 comporte, à sa partie supérieure, un orifice taraudé 21 à travers lequel est vissée
une vis de borne 22, 23. La vis de borne 22 du premier compartiment 2, présente
une extrémité bombée 22a, tandis que la vis 23 du second compartiment 3, est
rendue solidaire de préférence par sertissage d' un patin de serrage 24.Thus, it can be seen in FIG. 1, that the
Conformément à une réalisation particulière de l'invention, et comme ceci est
particulièrement visible sur les figures 2 à 5, ce patin de serrage 24 de forme
quadrangulaire est pourvu, au niveau de ses quatre angles, de quatre griffes 25 à
28 dirigées vers la plage de contact 6.In accordance with a particular embodiment of the invention, and as is
particularly visible in Figures 2 to 5, this
Ces quatre griffes 25 à 28 sont destinées à coopérer avec quatre évidements 29 à
32, ménagés dans la plage de contact correspondante 6, lesdits évidements 29 à 32

respectivement en regard de ces dernières.These four
Ainsi, ces bornes seront adaptées au serrage de câbles en aluminium lorsqu'elles
seront équipées d'une vis 22 à extrémité bombée 22a, et au serrage de câbles en
cuivre ou de multicâbles, lorsqu'elles seront équipées d'un patin 24 à griffes 25 à 28,
tel que précédemment décrit.Thus, these terminals will be adapted to the tightening of aluminum cables when they
will be fitted with a
En se reportant aux figures 4 et 5, on voit que la vis de borne 23 munie d'un patin 24
est également équipée d'un écran 33 de protection électrique. Cet écran 33 est
constitué par une pièce en forme de L, réalisée en matière plastique, dont l'une des
ailes 33a est montée librement tournante à la partie inférieure de la tige de la vis 23
en étant interposée entre le patin 24 et la partie supérieure 34 de la borne, tandis
que l'autre 33b des deux ailes 33a, 33b s'étend en direction de la partie supérieure
de la borne. Cet écran 33 est destiné à coopérer avec une ouverture de forme
correspondante 40 (visible sur la figure 1) ménagée dans une plaque cache-borne
41 placée sur la partie arrière du disjoncteur en fin de cablage, afin de réaliser une
protection électrique répondant à la norme IP2 de la manière qui sera décrite
ultérieurement. Referring to Figures 4 and 5, it can be seen that the
En se reportant plus particulièrement à la figure 6, on voit que dans les rainures
inférieures 18, 19 de l'un 5 des compartiments 2 à 5 a été introduit un écrou à oreille
20 placé sous la plage de contact 9 et destiné à permettre la fixation d'une cosse 42
sur ladite plage 9. A cet effet, deux orifices 43, 44 ont été respectivement prévus
dans la plage de contact 9 et dans la partie inférieure du compartiment 5, afin de
permettre le passage d'une vis de fixation 50 de la cosse 42 sur la plage 9, vissée
dans l'orifice 20b de l'écrou 20 à oreilles 20a.Referring more particularly to FIG. 6, it can be seen that in the grooves

Sur les figures 1 et 6, on voit que le boítier du disjoncteur est également pourvu sur
ses deux grandes faces opposées (dont seule l'une est visible sur cette figure) de
fiches de contact 46, destinées à alimenter au moyen de cosses fast-on 47, des
dispositifs tels que des voyants lumineux (non représentés) destinés à témoigner de
la présence ou de l'absence d'une tension.In Figures 1 and 6, we see that the circuit breaker housing is also provided on
its two large opposite faces (only one of which is visible in this figure) of
On notera que les rainures 18, 19 permettant la fixation de cosses à sertir 42
peuvent également servir à la fixation de barres en cuivre ou bien d'autres
accessoires de raccordement.It will be noted that the
On notera que les bornes et vis seront avantageusement réalisées en aluminium.It will be noted that the terminals and screws will advantageously be made of aluminum.
On remarquera également que dans le disjoncteur représenté sur la figure 1, toutes les plages de contact comportent des évidements.Note also that in the circuit breaker shown in Figure 1, all the contact pads have recesses.
On décrira ci-après brièvement les opérations de raccordement du disjoncteur avec les circuits électriques externes à protéger.The operations of connecting the circuit breaker with the external electrical circuits to be protected.
Sur les lieux d'installation, on introduira des homes telles que précédemment
décrites dans les compartiments 2 à 5 dont les plages de contacts 6 à 9 sont
destinées à être raccordées à des câbles. Lorsque les câbles seront des câbles en
aluminium, on équipera de préférence les cages d'une vis 22 à extrémité bombée
22a. Les évidements 29 à 32 prévus dans les plages 6 à 9 permettront déjà une
meilleure qualité de contact. On the installation sites, we will introduce homes as previously
described in
Lorsque les câbles seront des câbles en cuivre, ou bien multicâbles, les vis 23
seront équipées d'un patin 24 à griffes 25 à 28. Le serrage de la vis 23 entraínera
l'introduction des griffes du patin 24 dans les évidements 29 à 32 de la plage de
contact 6, les câbles étant ainsi retenus fermement entre le patin 24 et la plage 6,
d'où il résulte une meilleure qualité de contact. L'opération de serrage de la vis 23
entrainera également le déplacement vers le bas de l'écran 33 interposé entre le
bloc 14 et la plaque 41, jusqu'à ce que cet écran 33 obture l'ouverture
correspondante 40 de la plaque cache-bornes 41, de manière à réaliser une
isolation électrique vis à vis de l'extérieur de la borne, répondant à la norme IP2. On
notera que la plaque 41 aura été préalablement fixée sur la partie arrière du
disjoncteur par l'intermédiaire de rails 41a prévus sur la plaque 41 coopérant avec
des rainures 41 b formées dans le boitier.When the cables will be copper cables, or else multi-cable, the
Afin de procéder au raccordement d'une cosse à sertir 42, d' une barre en cuivre ou
