Definitions
- the present invention relates to a single-pole or multi-pole electrical protection switch comprising for each pole a housing provided with a coupling piece to the neighboring pole or to a juxtaposable additive device.
- Such coupling is used to transmit from one pole to another, or from one pole to a neighboring device, a mechanical signal for the purpose of triggering and / or signaling in the event of a fault or following an operation. voluntary.
- Such known multipolar devices generally require, to ensure coupling between the poles, a part or more coupling parts which must be attached by fitting or insertion on or in transmission parts belonging to the triggering mechanisms of the various poles.
- the object of the invention is in particular to simplify the design and mounting of a protective switch device with couplable poles by using a minimum number of component parts' suitable both for a single-pole version and for different multi-pole versions.
- a single-pole or multi-pole electrical protection switch comprising for each pole a prismatic insulating envelope provided with two lateral partitions, the first lateral partition forming part of an open housing, the second lateral partition belonging to a closing element attached to the housing for close the envelope, each plane of symmetry of a pole being separated from that of a neighboring pole by a distance called pole distance, each pole comprising a trigger mechanism with which is associated a movable transmission part in response to an actuation, the transmission part cooperating with a coupling part of said pole with a neighboring pole.
- the transmission part and the coupling part form a single part arranged for rotation in a bearing formed in the lateral partition of the housing and with an axis perpendicular to said partition, the coupling part having at first end a male coupling element and at a second end a female coupling element, these coupling elements being of complementary shapes to allow cooperation by direct interlocking of adjacent and coaxial coupling parts;
- the polar housing is in the form of a bowl housing the trigger mechanism and the coupling part.
- the protective switch can thus be produced with a small number of constituent parts, namely a polar box forming a bowl which contains the trigger mechanism and its combined transmission and coupling part, intermediate polar boxes of a single type forming as many bowls which contain the triggering mechanisms of the successive poles, and a cover for closing the bowl of the last pole.
- the assembly of the protective switch is facilitated by the stacking of polar cuvettes of low height and substantially identical, easy to store and to handle manually or automatically.
- each pole box is equipped with its coupling piece before stacking the next pole box, because its coupling piece is part of its own mechanism for triggering or opening the contacts.
- the part or the coupling parts do not protrude outside the side partitions of the unipolar or respectively multipolar envelope, and that the male coupling element of a first coupling part is housed in a recess a side wall of the envelope, the dimensions of the recess allowing the housing therein of the female coupling element of a second coupling part, coaxial and adjacent to the first.
- the recess is preferably bordered by at at least one bearing surface perpendicular to the axis of the coupling parts to receive a corresponding support collar provided on at least one of the coupling parts.
- the total width of the switch housing is expected to be slightly greater than a multiple of the pole pitch and the length of each coupling piece is slightly greater than the pole pitch.
- the switch illustrated in Figure 1 is three-pole; each of the poles P1, P2, P3 includes separable contacts in the event of detection of an electrical fault or in the event of voluntary operation.
- the triggering and operating mechanisms have not been indicated for the sake of clarity.
- the switch housing includes for the pole P1 an insulating pole-shaped housing A and for the poles P2 and P3 insulating pole boxes also in shape.
- bowl B the housing of pole P3 being closed by an insulating cover C; we understand that it is thus associated with each pole a closed prismatic envelope constituted on the one hand, by a bowl A or B and, on the other hand, as the case may be by the bottom of an adjacent bowl or by the cover C.
- the partitions of the bowl bottoms A, B and the partition of the cover C have thicknesses denoted e A , e B , e C respectively .
- the polar housing B differs slightly from the polar housing A in that it has nesting conformations D, while the outer wall of the housing A is smooth.
- the switch housing has elements (not shown) of attachment to a support such as a rail E or a perforated plate. The mutual fixing of the elements A, B, C is carried out for example by riveting.
- FIG. 1 shows the planes Yl-Y1, Y2-Y2, Y3-Y3 of symmetry for the terminals and the separable contacts of the poles Pl-P3, these planes being distant from each other by the polar pitch P.
- each polar envelope is housed a combined transmission and coupling part 10.
- the parts 10 are identical and arranged coaxially along an axis X-X perpendicular to the planes Y-Y.
- Each part 10 is part of the trigger mechanism of the respective pole; it is rotatably mounted in a bearing 11 formed in a side wall or partition 12A, 12B, 12C and it has at its first end 13 a male coupling element 14 and at its second end 15 a female coupling element 16 in which s 'fits the male element 14 of the adjacent coupling part.
- Each coupling end 10 emerges in a recess 17 formed in the wall 12A, 12B, 12C.
- the recess 17 is bordered by at least one bearing surface 18 perpendicular to the axis XX to receive a corresponding support flange 19 of the part 10.
- Such support surfaces and flanges can be provided at the two ends of the part 10.
- the coupling piece 10 has a length 1 which is less than the width L1 (or L2 or L3) of the corresponding polar envelope, but which is greater than the polar pitch P by a value at most equal to x, for example slightly lower by a set j to x. In this way, the coupling pieces 10 of adjacent poles fit together at a depth (x-j) without requiring additional pieces and without protruding from the external walls 12A and 12C to the left and to the right of the switch.
- FIG. 3 shows a three-pole protection switch which comprises a first column of pivoting coupling pieces 10 coaxial with axis Xl-Xl and a second column of pivoting coupling pieces 20 with coaxial axis X2-X2 parallel to Xl- Xl.
- Each part 10 is biased by a fault, magnetic and / or thermal tripping means, to act on a contact carrier 30 pivoting in the Y-Y plane via an intermediate actuating part 31; we see that the part 10 is part of the actuation mechanism of the pole considered.
- One of the parts 20 can be called up by means of voluntary opening of the contacts and resetting to act on the contact carrier 30 of the pole concerned.
- the rotary movement of the part 20 is transmitted to a neighboring part 20.
- the centerpiece 20 belongs to the central pole P2, it controls the slave parts 20 of the side poles P1, P3.
- the parts 20 are identical to each other and they offer in particular the same characteristics of conformation and length.
- the recesses 17 associated with the parts 10 and the homologous recesses 32 associated with the parts 20 pass through when they are arranged in the internal partitions 12B of the switch. They can be either through ( Figure 1) or blind and delimited by knockouts (Figure 3), to allow coupling to an additive juxtaposable to the switch when they are formed in the external partitions 12A, 12C of l 'light switch.
- the arrangement adopted for the couplable pole switch requires a minimum number of parts suitable for both the unipolar version and the various multipolar versions: cup A, cup B, cover C, coupling piece 10 for the automatic release and coupling part 20 for voluntary control and reset, without additional connecting parts.
- each pole box has an open front face
- a cover whose width is substantially that of the stack.
- This cover can therefore completely cover the open and projecting front part of the poles; moreover, it supports the voluntary opening and resetting means, for example the switch control button.
- the polar pitch is preferably a fraction of a normalized width, this fraction being equal to the ratio of two whole numbers chosen so as to make it possible to obtain, whatever the number of poles, a composition of modular devices whose width will be equal to a multiple of the standard width or, in the least favorable cases, will exceed the said multiple by an amount equal to half the standard width.
- W 9 mm
- W 9 mm
- the total width of the switch housing is much greater by a standard half-width 2 than an appropriate multiple of the pole pitch.
- the total width of a box with n poles can alternatively be greater by a standard width W than n times the pole pitch.

Description
La présente invention concerne un interrupteur électrique de protection unipolaire ou multipolaire comprenant pour chaque pôle un boîtier muni d'une pièce d'accouplement au pôle voisin ou à un appareil additif juxtaposable. Un tel couplage sert à transmettre d'un pôle à l'autre, ou d'un pôle à un appareil voisin, un signal mécanique dans un but de déclenchement et/ou de signalisation en cas de défaut ou à la suite d'une manoeuvre volontaire.The present invention relates to a single-pole or multi-pole electrical protection switch comprising for each pole a housing provided with a coupling piece to the neighboring pole or to a juxtaposable additive device. Such coupling is used to transmit from one pole to another, or from one pole to a neighboring device, a mechanical signal for the purpose of triggering and / or signaling in the event of a fault or following an operation. voluntary.
De tels appareils multipolaires connus nécessitent généralement pour assurer le couplage entre les pôles, une pièce ou plusieurs pièces d'accouplement qu'il faut rapporter par emboîtement ou insertion sur ou dans des pièces de transmission appartenant aux mécanismes de déclenchement des divers pôles.Such known multipolar devices generally require, to ensure coupling between the poles, a part or more coupling parts which must be attached by fitting or insertion on or in transmission parts belonging to the triggering mechanisms of the various poles.
Ainsi, dans le brevet FR 1 596 145, il est proposé de réaliser un interrupteur unipolaire ou multipolaire comprenant dans sa version unipolaire un boîtier et un couvercle et dans sa version multipolaire un boîtier, des pièces intermédiaires disposées en nombre égal au nombre de pôles souhaité et un couvercle ; chaque pôle comporte un levier qui contribue à'l'accouplement grâce à un axe commun de montage traversant, cet axe couplant les divers leviers. Il est donc nécessaire de prévoir des axes de différentes longueurs pour accoupler les leviers lors de la fabrication d'interrupteurs à nombres de pôles différents.Thus, in the patent FR 1 596 145, it is proposed to produce a single-pole or multi-pole switch comprising in its single-pole version a housing and a cover and in its multi-pole version a housing, intermediate parts arranged in number equal to the number of poles desired and a cover; each pole has a lever which contributes to coupling thanks to a common through-mounting axis, this axis coupling the various levers. It is therefore necessary to provide axes of different lengths to couple the levers when manufacturing switches with different number of poles.
Il existe d'autres interrupteurs de protection unipolaires ou multipolaires accouplables, mais ces interrupteurs ont pour inconvénient d'exiger soit un nombre de pièces élevé pour bâtir les boîtiers et les accouplements de la version unipolaire et des différentes versions multipolaires, soit un encombrement en largeur trop important du boîtier à cause des saillies des pièces d'accouplement.There are other single-pole or multi-pole protective switches that can be coupled, but these switches have the disadvantage of requiring either a high number of parts to build the housings and couplings of the single-pole version and of the various multi-pole versions, or a space requirement in width. too large of the housing due to the projections of the coupling parts.
L'invention a notamment pour but de simplifier la conception et le montage d'un appareil interrupteur de protection à pôles accouplables en utilisant un nombre minimal de pièces constituantes 'adaptées aussi bien à une version unipolaire qu'aux différentes versions multipolaires.The object of the invention is in particular to simplify the design and mounting of a protective switch device with couplable poles by using a minimum number of component parts' suitable both for a single-pole version and for different multi-pole versions.
Elle a pour autre but, tout en simplifiant la réalisation d'un tel appareil interrupteur de protection, de conférer à celui-ci une épaisseur minimale entraînant un faible encombrement en largeur et autorisant le cas échéant la réalisation de versions modulaires.It has the other aim, while simplifying the production of such a protective switch device, of giving it a minimum thickness resulting in a small overall width and authorizing, where appropriate, the production of modular versions.
Elle concerne un interrupteur électrique de protection unipolaire ou multipolaire comprenant pour chaque pôle une enveloppe isolante prismatique munie de deux cloisons latérales, la première cloison latérale faisant partie d'un boîtier ouvert, la deuxième cloison latérale appartenant à un élément de fermeture rapporté au boîtier pour fermer l'enveloppe, chaque plan de symétrie d'un pôle étant séparé de celui d'un pôle voisin d'une distance dite pas polaire, chaque pôle comprenant un mécanisme déclencheur auquel est associée une pièce de transmission déplaçable en réponse à un actionnement, la pièce de transmission coopérant avec une pièce d'accouplement dudit pôle avec un pôle voisin. Selon l'invention, la pièce de transmission et la pièce d'accouplement forment une seule pièce disposée à rotation dans un palier ménagé dans la cloison latérale du boîtier et d'axe perpendiculaire à ladite cloison, la pièce d'accouplement présentant à une première extrémité un élément de couplage mâle et à une deuxième extrémité un élément de couplage femelle, ces éléments de couplage étant de formes complémentaires pour permettre une coopération par emboîtement direct de pièces d'accouplement adjacentes et coaxiales ; de plus, le boîtier polaire est en forme de cuvette logeant le mécanisme déclencheur et la pièce d'accouplement.It relates to a single-pole or multi-pole electrical protection switch comprising for each pole a prismatic insulating envelope provided with two lateral partitions, the first lateral partition forming part of an open housing, the second lateral partition belonging to a closing element attached to the housing for close the envelope, each plane of symmetry of a pole being separated from that of a neighboring pole by a distance called pole distance, each pole comprising a trigger mechanism with which is associated a movable transmission part in response to an actuation, the transmission part cooperating with a coupling part of said pole with a neighboring pole. According to the invention, the transmission part and the coupling part form a single part arranged for rotation in a bearing formed in the lateral partition of the housing and with an axis perpendicular to said partition, the coupling part having at first end a male coupling element and at a second end a female coupling element, these coupling elements being of complementary shapes to allow cooperation by direct interlocking of adjacent and coaxial coupling parts; in addition, the polar housing is in the form of a bowl housing the trigger mechanism and the coupling part.
L'interrupteur de protection peut ainsi être réalisé avec un faible nombre de pièces constituantes, à savoir un boîtier polaire formant une cuvette qui contient le mécanisme déclencheur et sa pièce combinée de transmission et d'accouplement, des boîtiers polaires intermédiaires d'un seul type formant autant de cuvettes qui contiennent les mécanismes déclencheurs des pôles successifs, et un couvercle pour fermer la cuvette du dernier pôle. L'assemblage de l'interrupteur de protection est facilité par l'empilage des cuvettes polaires de hauteur faible et sensiblement identique, faciles à stocker et à manipuler de façon manuelle ou automatisée. En particulier, chaque boîtier polaire est équipé de sa pièce d'accouplement avant l'empilage du boîtier polaire suivant, du fait que sa pièce d'accouplement fait partie de son mécanisme propre de déclenchement ou d'ouverture des contacts.The protective switch can thus be produced with a small number of constituent parts, namely a polar box forming a bowl which contains the trigger mechanism and its combined transmission and coupling part, intermediate polar boxes of a single type forming as many bowls which contain the triggering mechanisms of the successive poles, and a cover for closing the bowl of the last pole. The assembly of the protective switch is facilitated by the stacking of polar cuvettes of low height and substantially identical, easy to store and to handle manually or automatically. In particular, each pole box is equipped with its coupling piece before stacking the next pole box, because its coupling piece is part of its own mechanism for triggering or opening the contacts.
Il est avantageux que la pièce ou les pièces d'accouplement ne fassent pas saillie hors des cloisons latérales de l'enveloppe unipolaire ou respectivement multipolaire, et que l'élément de couplage mâle d'une première pièce d'accouplement soit logé dans un évidement d'une cloison latérale de l'enveloppe, les dimensions de l'évidement autorisant le logement dans celui-ci de l'élément de couplage femelle d'une deuxième pièce d'accouplement, coaxiale et adjacente à la première. L'évidement est de préférence bordé par au moins une surface d'appui perpendiculaire à l'axe des pièces d'accouplement pour recevoir une collerette d'appui correspondante prévue sur l'une au moins des pièces d'accouplement.It is advantageous that the part or the coupling parts do not protrude outside the side partitions of the unipolar or respectively multipolar envelope, and that the male coupling element of a first coupling part is housed in a recess a side wall of the envelope, the dimensions of the recess allowing the housing therein of the female coupling element of a second coupling part, coaxial and adjacent to the first. The recess is preferably bordered by at at least one bearing surface perpendicular to the axis of the coupling parts to receive a corresponding support collar provided on at least one of the coupling parts.
De préférence, en combinaison avec le fait que la pile de pièces d'accouplement ne dépasse pas du boîtier de l'interrupteur, la largeur totale du boîtier de l'interrupteur est prévue légèrement supérieure à un multiple du pas polaire et la longueur de chaque pièce d'accouplement est légèrement supérieure au pas polaire.Preferably, in combination with the fact that the stack of coupling parts does not protrude from the switch housing, the total width of the switch housing is expected to be slightly greater than a multiple of the pole pitch and the length of each coupling piece is slightly greater than the pole pitch.
La description qui suit d'un mode de réalisation non limitatif en regard des dessins annexés va expliciter d'autres caractéristiques et avantages de l'invention.
- La figure 1 représente schématiquement en coupe un interrupteur de protection tripolaire conforme à l'invention ;
- La figure 2 représente une coupe axiale d'une pièce d'accouplement de l'interrupteur ;
- La figure 3 montre de manière un peu plus détaillée une variante de l'interrupteur de la figure 1.
- Figure 1 shows schematically in section a three-pole protection switch according to the invention;
- FIG. 2 represents an axial section of a coupling part of the switch;
- FIG. 3 shows in a little more detail a variant of the switch of FIG. 1.
L'interrupteur illustré sur la figure 1 est tripolaire ; chacun des pôles Pl, P2, P3 comprend des contacts séparables en cas de détection de défaut électrique ou en cas de manœu- vre volontaire. Les mécanismes de déclenchement et de manoeuvre n'ont pas été indiqués dans un but de clarté.The switch illustrated in Figure 1 is three-pole; each of the poles P1, P2, P3 includes separable contacts in the event of detection of an electrical fault or in the event of voluntary operation. The triggering and operating mechanisms have not been indicated for the sake of clarity.
Le boîtier de l'interrupteur comprend pour le pôle Pl un boîtier polaire isolant en forme de cuvette A et pour les pôles P2 et P3 des boîtiers polaires isolants également en forme. de cuvette B, le boîtier du pôle P3 étant fermé par un couvercle isolant C ; on comprend qu'il est ainsi associé à chaque pôle une enveloppe prismatique fermée constituée, d'une part, par une cuvette A ou B et, d'autre part, selon le cas par le fond d'une cuvette adjacente ou par le couvercle C. Les cloisons des fonds de cuvettes A, B et la cloison du couvercle C ont respectivement des épaisseurs notées eA, eB, eC. Le boîtier polaire B diffère légèrement du boîtier polaire A du fait qu'il présente des conformations d'emboîtement D, tandis que la paroi externe du boîtier A est lisse. Le boîtier de l'interrupteur présente des éléments non représentés de fixation sur un support tel qu'un rail E ou une platine perforée. La fixation mutuelle des éléments A, B, C s'effectue par exemple par rivetage.The switch housing includes for the pole P1 an insulating pole-shaped housing A and for the poles P2 and P3 insulating pole boxes also in shape. of bowl B, the housing of pole P3 being closed by an insulating cover C; we understand that it is thus associated with each pole a closed prismatic envelope constituted on the one hand, by a bowl A or B and, on the other hand, as the case may be by the bottom of an adjacent bowl or by the cover C. The partitions of the bowl bottoms A, B and the partition of the cover C have thicknesses denoted e A , e B , e C respectively . The polar housing B differs slightly from the polar housing A in that it has nesting conformations D, while the outer wall of the housing A is smooth. The switch housing has elements (not shown) of attachment to a support such as a rail E or a perforated plate. The mutual fixing of the elements A, B, C is carried out for example by riveting.
En interdépendance avec le pas polaire P et les épaisseurs eA, eB, eC des cloisons externes et internes de l'interrupteur, la largeur totale L du boîtier de l'interrupteur est prévue légèrement supérieure à un multiple du pas polaire ; par exemple avec n pôles, L = nP + x.In interdependence with the pole pitch P and the thicknesses e A , e B , e C of the external and internal partitions of the switch, the total width L of the switch housing is provided slightly greater than a multiple of the pole pitch; for example with n poles, L = nP + x.
On a représenté sur la figure 1 les plans Yl-Y1, Y2-Y2, Y3-Y3 de symétrie pour les bornes et les contacts séparables des pôles Pl-P3, ces plans étant distants entre eux du pas polaire P.FIG. 1 shows the planes Yl-Y1, Y2-Y2, Y3-Y3 of symmetry for the terminals and the separable contacts of the poles Pl-P3, these planes being distant from each other by the polar pitch P.
Dans chaque enveloppe polaire est logée une pièce combinée de transmission et d'accouplement 10. Les pièces 10 sont identiques et disposées coaxialement selon un axe X-X perpendiculaire aux plans Y-Y. Chaque pièce 10 fait partie du mécanisme déclencheur du pôle respectif ; elle est montée à rotation dans un palier 11 ménagé dans une paroi ou cloison latérale 12A, 12B, 12C et elle présente à sa première extrémité 13 un élément de couplage mâle 14 et à sa deuxième extrémité 15 un élément de couplage femelle 16 dans lequel s'emboîte l'élément mâle 14 de la pièce d'accouplement adjacente.In each polar envelope is housed a combined transmission and
Chaque extrémité d'accouplement 10 émerge dans un évidement 17 ménagé dans la paroi 12A, 12B, 12C. L'évidement 17 est bordé par au moins une surface d'appui 18 perpendiculaire à l'axe X-X pour recevoir une collerette d'appui correspondante 19 de la pièce 10. De telles surfaces d'appui et collerettes peuvent être prévues aux deux extrémités de la pièce 10.Each
La pièce d'accouplement 10 présente une longueur 1 qui est inférieure à la largeur Ll (ou L2 ou L3) de l'enveloppe polaire correspondante, mais qui est supérieure au pas polaire P d'une valeur au plus égale à x, par exemple légèrement inférieure d'un jeu j à x. De cette manière, les pièces d'accouplement 10 de pôles adjacents s'emboîtent d'une profondeur (x-j) sans nécessiter de pièces additionnelles et sans dépasser des parois externes 12A et 12C à gauche et à droite de l'interrupteur.The
La figure 3 montre un interrupteur de protection tripolaire qui comporte une première colonne de pièces pivotantes d'accouplement 10 coaxiales d'axe Xl-Xl et une deuxième colonne de pièces pivotantes d'accouplement 20 coaxiales d'axe X2-X2 parallèle à Xl-Xl. Chaque pièce 10 est sollicitée par un moyen de déclenchement sur défaut, magnétique et/ou thermique, pour agir sur un porte-contact 30 pivotant dans le plan Y-Y via une pièce intermédiaire d'actionnement 31 ; on constate que la pièce 10 fait partie du mécanisme d'actionnement du pôle considéré.FIG. 3 shows a three-pole protection switch which comprises a first column of pivoting
L'une des pièces 20 est sollicitable par un moyen d'ouverture volontaire des contacts et de réarmement pour agir sur le porte-contact 30 du pôle concerné. Le mouvement rotatif de la pièce 20 est transmis à une pièce 20 voisine. Si la pièce maîtresse 20 appartient au pôle central P2, elle commande les pièces esclaves 20 des pôles latéraux Pl, P3. Les pièces 20 sont identiques entre elles et elles offrent en particulier les mêmes caractéristiques de conformation et de longueur.One of the
Les évidements 17 associés aux pièces 10 et les évidements homologues 32 associés aux pièces 20 sont traversants lorsqu'ils sont ménagés dans les cloisons internes 12B de l'interrupteur. Ils peuvent être soit traversants (figure 1), soit borgnes et délimités par des voiles défonçables (figure 3), pour autoriser l'accouplement à un additif juxtaposable à l'interrupteur lorsqu'ils sont ménagés dans les cloisons externes 12A, 12C de l'interrupteur.The
Il faut noter que la disposition adoptée pour l'interrupteur à pôles accouplables requiert un nombre minimal de pièces convenant aussi bien à la version unipolaire qu'aux différentes versions multipolaires : cuvette A, cuvette B, couvercle C, pièce d'accouplement 10 pour le déclenchement automatique et pièce d'accouplement 20 pour la commande et le réarmement volontaires, sans pièces additionnelles de liaison.It should be noted that the arrangement adopted for the couplable pole switch requires a minimum number of parts suitable for both the unipolar version and the various multipolar versions: cup A, cup B, cover C,
Dans le cas où chaque boîtier polaire présente une face avant ouverte, il est intéressant de rapporter sur le boîtier unipolaire ou multipolaire de l'interrupteur un capot dont la largeur est sensiblement celle de l'empilage. Ce capot peut donc recouvrir en totalité la partie avant ouverte et saillante des pôles ; de plus, il supporte le moyen d'ouverture volontaire et de réarmement, par exemple le bouton de commande de l'interrupteur.In the case where each pole box has an open front face, it is advantageous to attach to the single-pole or multi-pole box of the switch a cover whose width is substantially that of the stack. This cover can therefore completely cover the open and projecting front part of the poles; moreover, it supports the voluntary opening and resetting means, for example the switch control button.
On peut ainsi préassembler l'organe de commande sur le capot pour rapporter le tout par encliquetage sur l'avant du boîtier.It is thus possible to pre-assemble the control member on the cover to bring everything together by snapping onto the front of the housing.
Le pas polaire est de préférence une fraction d'une largeur normalisée, cette fraction étant égale au rapport de deux nombres entiers choisis de manière à permettre d'obtenir quel que soit le nombre de pôles une composition d'appareils modulaires dont la largeur sera égale à un multiple de la largeur normalisée ou, dans les cas les moins favorables, excédera ledit multiple d'une quantité égale à la moitié de la largeur normalisée.The polar pitch is preferably a fraction of a normalized width, this fraction being equal to the ratio of two whole numbers chosen so as to make it possible to obtain, whatever the number of poles, a composition of modular devices whose width will be equal to a multiple of the standard width or, in the least favorable cases, will exceed the said multiple by an amount equal to half the standard width.
Exemple 1 : avec une largeur normalisée W = 9 mm, le pas polaire P est de préférence choisi égal à
Exemple 2 : avec la même largeur normalisée W = 9 mm, le pas polaire est de préférence choisi égal à
Il convient d'observer que, dans chaque cas, la largeur totale du boîtier de l'interrupteur est bien supérieure d'une demi-largeur normalisée 2 à un multiple approprié du pas polaire. La largeur totale d'un boîtier à n pôles peut en variante être supérieure d'une largeur normalisée W à n fois le pas polaire.It should be observed that, in each case, the total width of the switch housing is much greater by a standard half-width 2 than an appropriate multiple of the pole pitch. The total width of a box with n poles can alternatively be greater by a standard width W than n times the pole pitch.
