Description

La présente invention se rapporte à un ensemble de protection et de commande électromagnétique permettant une association de plusieurs appareils électriques interrupteurs multipolaires, en particulier pour la réalisation d'un ensemble comportant une pluralité d'appareils électriques tels que contacteur, disjoncteur ou autre appareil électrique analogue, utilisables en distribution ou commande électrique basse tension. L'invention concerne également un appareil électrique susceptible d'entrer dans la composition d'un tel ensemble de protection et de commande.The present invention relates to a protection and electromagnetic control assembly allowing a combination of several multipolar electrical switchgear devices, in particular for producing an assembly comprising a plurality of electrical appliances such as contactor, circuit breaker or other similar electrical appliance. , usable in distribution or low voltage electrical control. The invention also relates to an electrical apparatus capable of forming part of the composition of such a protection and control assembly.

Dans un ensemble destiné à la protection et à la commande d'un moteur électrique (généralement appelé un "ensemble de départ moteur") ou de toute autre charge électrique multipolaire en basse tension, on associe fréquemment en cascade un appareil électrique de protection, tel qu'un disjoncteur ou un sectionneur porte-fusibles avec un appareil électrique de commande, tel qu'un contacteur. On peut aussi ajouter à cette association d'autres appareils comme un relais thermique de protection. De plus, on peut vouloir associer plusieurs appareils de commande dans un même ensemble de départ moteur de façon à réaliser une fonction logique, en particulier une fonction d'inverseur.In an assembly intended for the protection and control of an electric motor (generally called a "motor starter unit") or of any other low voltage multipolar electric charge, a protective electric apparatus is frequently associated in cascade, such as a circuit breaker or fuse switch with an electrical control device, such as a contactor. It is also possible to add to this association other devices such as a protective thermal relay. In addition, it may be desired to associate several control devices in the same motor starter assembly so as to perform a logic function, in particular an inverter function.

On cherche de plus en plus àinstaller un tel ensemble de départ moteur le plus simplement et le plus rapidement possible tout en conservant une connexion électrique fiable. Pour des raisons évidentes de coût, de gain de temps lors du montage/câblage et de gain de place dans les coffrets ou armoires électriques accueillant l'ensemble, on cherche notamment à supprimer d'éventuels conducteurs (fils, barres) de raccordement entre les appareils, àminimiser le nombre de raccordements électriques à effectuer et à minimiser l'encombrement total des différents appareils associés. Par ailleurs, l'ensemble monté doit garder un accès facile pour le raccordement de ses borniers de puissance avec des conducteurs extérieurs, tels que des câbles ou des barres.We are looking more and more to install such an engine starter assembly as simply and as quickly as possible while maintaining a reliable electrical connection. For obvious reasons of cost, time saving during assembly / wiring and saving space in enclosures or electrical cabinets hosting the whole, it seeks in particular to remove any conductors (wires, bars) connection between the devices, to minimize the number of electrical connections to be made and to minimize the total size of the various associated devices. Furthermore, the mounted assembly must keep easy access for the connection of its power terminal blocks with external conductors, such as cables or bars.

Le document EP1100105 décrit un dispositif de précâblage entre deux contacteurs multipolaires. On y propose des modules de précâblage amont et aval permettant de réaliser rapidement une fonction logique déterminée entre les deux contacteurs. Dans ce document, les modules amont viennent se positionner en amont des borniers de puissance amont et les modules aval viennent se positionner en aval des borniers de puissance aval des appareils. De ce fait, les modules gênent l'accès aux borniers de puissance pour l'introduction de conducteurs extérieurs, surtout dans le cas d'appareils de forte puissance électrique nécessitant des conducteurs extérieurs de section importante, comme par exemple avec un courant électrique supérieur ou égal à 32A sous 400V. De plus, si l'on veut rajouter àl'ensemble un appareil électrique supplémentaire, par exemple un disjoncteur en amont des deux contacteurs ou un relais thermique en aval des deux contacteurs, cette solution nécessite toujours l'utilisation de deux borniers de puissance par appareil.The document EP1100105 describes a pre-wiring device between two multipolar contactors. It offers pre-wiring modules upstream and downstream to quickly achieve a logical function determined between the two contactors. In this document, the upstream modules are positioned upstream of the upstream power terminal blocks and the downstream modules are positioned downstream of the downstream power terminals of the devices. As a result, the modules interfere with access to the power terminal blocks for the introduction of external conductors, especially in the case of devices with a high electrical power requiring external conductors of large cross-section, for example with a higher electric current or equal to 32A at 400V. In addition, if we want to add to the assembly an additional electrical device, for example a circuit breaker upstream of the two contactors or a thermal relay downstream of the two contactors, this solution always requires the use of two power terminals per device .

L'invention a donc pour but de faciliter la mise en place d'une association électrique de plusieurs appareils électriques dans le but de réaliser de manière simple, fiable et économique un ensemble de protection et de commande et permettant de réaliser facilement une fonction logique.The invention therefore aims to facilitate the establishment of an electrical combination of several electrical devices in order to achieve a simple, reliable and economical protection and control assembly and to easily achieve a logical function.

Pour cela, l'invention décrit un ensemble de protection et de commande comprenant une pluralité d'appareils électriques interrupteurs multipolaires possédant chacun un boîtier muni de barrettes conductrices de connexion amont et aval, qui viennent en saillie selon un axe vertical sur une plage de raccordement horizontale amont et aval du boîtier et qui sont susceptibles d'être insérées dans des ouvertures de borniers de puissance amovibles. L'ensemble comprend au moins un élément de liaison qui relie électriquement les pôles d'un premier et d'un second appareil électrique de l'ensemble de protection et de commande, l'élément de liaison étant agencé de façon àse positionner d'une part entre le boîtier et un bornier de puissance amovible du premier appareil électrique, d'autre part entre le boîtier et un bornier de puissance amovible du second appareil électrique.For this, the invention describes a protection and control assembly comprising a plurality of multipolar electrical switchgear devices each having a housing provided with upstream and downstream conductive connection strips, which project from a vertical axis over a connection pad. horizontal upstream and downstream of the housing and which may be inserted into removable power terminal openings. The assembly comprises at least one connecting element which electrically connects the poles of a first and a second electrical appliance of the protection and control assembly, the connecting element being arranged so as to position a part between the housing and a removable power terminal of the first electrical device, on the other hand between the housing and a removable power terminal of the second electrical device.

Selon une caractéristique, chaque élément de liaison comporte des premières broches de connexion reliées à des secondes broches de connexion. Ces broches viennent en saillie selon l'axe vertical et sont insérables dans des ouvertures de borniers de puissance amovibles. Les broches de connexion d'un élément de liaison sont plaquées contre des barrettes de connexion de boîtiers des appareils électriques.According to one characteristic, each connecting element comprises first connection pins connected to second connection pins. These pins protrude along the vertical axis and are insertable into removable power terminal openings. The connecting pins of a connecting element are pressed against the terminal strips of the electrical appliances.

Selon une autre caractéristique, l'élément de liaison possède des organes de maintien aptes à coopérer avec des moyens complémentaires disposés dans les boîtiers des appareils électriques. Les organes de maintien sont constitués préférentiellement par un ou plusieurs ergots disposés sur au moins une face horizontale de l'élément de liaison.According to another characteristic, the connecting element has holding members adapted to cooperate with complementary means arranged in the housings of electrical appliances. The holding members are constituted preferably by one or more lugs arranged on at least one horizontal face of the connecting element.

Selon une autre caractéristique, l'ensemble comprend un élément de liaison amont dont les premières broches sont en contact avec les barrettes de connexion amont du boîtier du premier appareil électrique et dont les secondes broches sont en contact avec les barrettes de connexion amont du boîtier du second appareil électrique. L'ensemble comprend également un élément de liaison aval dont les premières broches sont en contact avec les barrettes de connexion aval du boîtier du premier appareil électrique et dont les secondes broches sont en contact avec les barrettes de connexion aval du boîtier du second appareil électrique. Pour réaliser une fonction d'inverseur, l'élément de liaison amont reliant les barrettes amont des boîtiers de deux appareils électriques tripolaires réalise en interne une fonction d'inversion de deux pôles des appareils électriques.According to another feature, the assembly comprises an upstream connection element whose first pins are in contact with the upstream connection strips of the housing of the first electrical appliance and whose second pins are in contact with the upstream connection bars of the housing of the second electrical apparatus. The assembly also comprises a downstream connecting element whose first pins are in contact with the downstream connection strips of the housing of the first electrical appliance and whose second pins are in contact with the downstream connection bars of the housing of the second electrical appliance. In order to perform an inverter function, the upstream link element connecting the upstream bars of the housings of two three-pole electrical appliances internally performs a function of inverting two poles of the electrical appliances.

Selon une autre caractéristique, l'invention décrit un ensemble comprenant un élément de liaison série dont les premières broches sont en contact avec les barrettes de connexion aval du boîtier d'un premier appareil électrique et dont les secondes broches sont en contact avec les barrettes de connexion amont du boîtier d'un second appareil électrique, positionné àcôté du premier appareil électrique.According to another characteristic, the invention describes an assembly comprising a serial link element whose first pins are in contact with the downstream connection bars of the housing of a first electrical appliance and whose second pins are in contact with the bars of upstream connection of the housing of a second electrical appliance, positioned adjacent to the first electrical appliance.

Les figures 1 et 2 présentent un exemple de réalisation d'un ensemble de protection et de commande selon l'invention. Cet ensemble comporte trois appareils électriques, en l'occurrence un disjoncteur 30 et deux contacteurs 10,20. L'invention permettrait de façon équivalente de réaliser un ensemble comprenant en outre par exemple un relais thermique en aval d'un des contacteurs. De plus, il est clair que l'invention peut aussi s'appliquer àtout autre appareil électrique utilisable en distribution ou commande électrique basse tension.The figures 1 and 2 show an exemplary embodiment of a protection and control assembly according to the invention. This set comprises three electrical devices, in this case a circuit breaker 30 and two contactors 10,20. The invention would equivalently make an assembly further comprising for example a thermal relay downstream of one of the contactors. In addition, it is clear that the invention can also be applied to any other electrical appliance used in distribution or low voltage electrical control.

Les figures 3 et 4 représentent un appareil électrique interrupteur multipolaire, par exemple du type disjoncteur, comprenant un boîtier 30 et susceptible de s'intégrer dans un tel ensemble de protection et de commande. La figure 7 représente un autre appareil électrique interrupteur multipolaire, par exemple du type contacteur, comprenant un boîtier 10 et susceptible aussi de s'intégrer dans un tel ensemble de protection et de commande.The Figures 3 and 4 represent a multipole electrical switch device, for example of the circuit breaker type, comprising a housing 30 and capable of integrating into such a protection and control assembly. The figure 7 represents another electrical multipole switch device, for example of the contactor type, comprising a housing 10 and also capable of integrating into such a protection and control assembly.

Chaque boîtier 10, respectivement 30, est de forme globalement parallélépipédique avec une face avant 11, respectivement 31, pouvant comporter un organe de manoeuvre opposée à une face arrière 12, respectivement 32, pouvant comporter des moyens de fixation de l'appareil sur un châssis, un profilé et/ou une platine. Chaque boîtier 10, respectivement 30, possède une face sensiblement horizontale amont 13b,14b, respectivement 33b,34b, opposée àune face sensiblement horizontale aval 13a,14a, respectivement 33a,34a. Des barrettes conductrices de connexion amont 19b, respectivement 39b, viennent en saillie sur la face amont 13b,14b respectivement 33b,34b, du boîtier 10, respectivement 30, selon un axe vertical X. Des barrettes conductrices de connexion aval 19a, respectivement 39a, viennent en saillie sur la face aval 13a,14a, respectivement 33a,34a, du boîtier 10, respectivement 30, selon le même axe vertical X, mais dans une direction opposée.Each casing 10, respectively 30, is of generally parallelepipedal shape with a front face 11, respectively 31, which may comprise an operating member opposite to a rear face 12, respectively 32, which may comprise means for fixing the apparatus on a frame , a profile and / or a plate. Each housing 10, respectively 30, has a substantially horizontal upstream face 13b, 14b, respectively 33b, 34b, opposite a substantially horizontal downstream face 13a, 14a, respectively 33a, 34a. Conducting upstream connection strips 19b, respectively 39b, protrude from the upstream face 13b, 14b respectively 33b, 34b, of the housing 10, respectively 30, along a vertical axis X. Downstream conductor busbars 19a, respectively 39a, protrude on the downstream face 13a, 14a, respectively 33a, 34a, of the housing 10, respectively 30, along the same vertical axis X, but in an opposite direction.

Bien entendu, à chacun des pôles de l'appareil interrupteur correspond une barrette amont et une barrette aval correspondante, destinées àl'arrivée et au départ du courant électrique dans ce pôle. Les exemples présentés dans les figures 3, 4 et 7 comportent trois barrettes amont et trois barrettes aval, schématisant ainsi des appareils tripolaires. Dans un mode de réalisation préféré de l'invention, les appareils interrupteurs possèdent des barrettes conductrices 19a, 19b, respectivement 39a,39b, rigides, de section rectangulaire identique et de taille suffisante pour la circulation d'un courant de forte puissance, par exemple supérieur ou égal à 32A sous 400V. Habituellement, les barrettes conductrices sont métalliques, en particulier en cuivre.Of course, at each of the poles of the switch device corresponds an upstream strip and a corresponding downstream strip for the arrival and departure of the electric current in this pole. The examples presented in Figures 3, 4 and 7 have three upstream and three downstream bars, thus schematizing three-pole devices. In a preferred embodiment of the invention, the switchgear devices have conductive strips 19a, 19b, respectively 39a, 39b, rigid, of identical rectangular section and of sufficient size for the circulation of a high power current, for example greater than or equal to 32A at 400V. Usually, the conductive strips are metallic, in particular copper.

Préférentiellement, la face horizontale aval 13a,14a, respectivement 33a,34a, et la face horizontale amont 13b,14b, respectivement 33b,34b, d'un boîtier 10, respectivement 30, sont formées par plusieurs plans horizontaux décalés l'un par rapport à l'autre. Ainsi, la face horizontale aval est constituée d'une plage d'appui aval 13a, respectivement 33a, sensiblement horizontale ainsi que d'une plage de raccordement aval 14a, respectivement 34a, décalée sensiblement horizontale. Les barrettes conductrices aval 19a, respectivement 39a, sortent de la plage de raccordement aval 14a, respectivement 34a. De même, la face horizontale amont est constituée d'une plage d'appui amont 13b, respectivement 33b, sensiblement horizontale ainsi que d'une plage de raccordement amont 14b, respectivement 34b, décalée sensiblement horizontale. Les barrettes conductrices amont 19b, respectivement 39b sortent de la plage de raccordement amont 14b, respectivement 34b. Les plages d'appui aval 13a et amont 13b, respectivement 33a et 33b, sont plus proches de la face arrière 12, respectivement 32, du boîtier 10, respectivement 30, et sont plus écartées l'une de l'autre que les plages de raccordement aval 14a et amont 14b, respectivement 34a et 34b.Preferably, the downstream horizontal face 13a, 14a, respectively 33a, 34a, and the upstream horizontal face 13b, 14b, respectively 33b, 34b, of a housing 10, respectively 30, are formed by several horizontal planes offset relative to one another. to the other. Thus, the downstream horizontal face consists of a downstream bearing surface 13a, respectively 33a, substantially horizontal and a downstream connection zone 14a, respectively 34a, shifted substantially horizontally. The downstream conductor strips 19a, respectively 39a, come out of the downstream connection pad 14a, respectively 34a. Similarly, the upstream horizontal face consists of an upstream bearing surface 13b, respectively 33b, substantially horizontal and an upstream connection area 14b, respectively 34b, offset substantially horizontally. The upstream conductor strips 19b and 39b respectively come out of the upstream connection zone 14b, respectively 34b. The downstream support pads 13a and upstream 13b, respectively 33a and 33b, are more close to the rear face 12, respectively 32, of the housing 10, respectively 30, and are further apart than the downstream connection pads 14a and upstream 14b, respectively 34a and 34b.

Les plages de raccordement aval et amont des boîtiers 10,30 sont agencées pour recevoir chacune un bornier de puissance amovible 40 de façon à permettre le raccordement électrique des barrettes de connexion 19a,19b,39a,39b avec des conducteurs extérieurs. Un tel bornier de puissance 40, représenté aux figures 5 et 6, possède évidemment autant de bornes de puissance que de pôles de l'appareil interrupteur sur lequel il doit être monté. Il est de forme parallélépipédique avec deux faces horizontales 41,49 opposées et une face avant verticale permettant d'accéder à des vis de serrage 42 des bornes. Pour chaque borne du bornier de puissance 40, il existe une ouie d'ouverture verticale 44 traversant les faces horizontales 41,49 et permettant d'insérer un ou plusieurs conducteurs électriques perpendiculairement à l'axe des vis 42. La largeur d'un bornier 40 est sensiblement égale àcelle des boîtiers 10,30.The downstream and upstream connection areas of the boxes 10, 30 are arranged to each receive a removable power terminal block 40 so as to allow the electrical connection of the connection strips 19a, 19b, 39a, 39b with external conductors. Such a power terminal block 40, shown in FIGS. Figures 5 and 6 , obviously has as many power terminals as poles of the switch device on which it must be mounted. It is of parallelepipedal shape with two opposite horizontal faces 41,49 and a vertical front face allowing access to clamping screws 42 of the terminals. For each terminal of the power terminal block 40, there is a vertical aperture opening 44 through the horizontal faces 41,49 and for inserting one or more electrical conductors perpendicular to the axis of the screws 42. The width of a terminal block 40 is substantially equal to that of the housings 10,30.

Ainsi, chaque barrette de connexion 19a,19b, respectivement 39a,39b, se trouve insérée dans une ouverture correspondante 44 lorsqu'une des faces horizontales 41,49 d'un bornier de connexion 40 est plaquée contre une plage de raccordement 14a,14b, respectivement 34a,34b, d'un boîtier 10, respectivement 30. De façon classique, chaque borne d'un bornier de puissance 40 comprend une vis de serrage 42 coopérant avec une cage de serrage 43 située dans l'ouverture 44 correspondante de la borne. Lorsqu'on serre la vis 42, on déforme la cage 43 de façon à ce que celle-ci vienne enserrer les conducteurs présents dans l'ouverture 44. Ce serrage permet d'effectuer un raccordement électrique efficace de la barrette de connexion avec tout autre conducteur préalablement inséré dans l'ouverture 44, et permet en outre de fixer le bornier de connexion 40 contre le boîtier de l'appareil interrupteur.Thus, each connection strip 19a, 19b, respectively 39a, 39b, is inserted into a corresponding opening 44 when one of the horizontal faces 41,49 of a connection terminal block 40 is pressed against a connection pad 14a, 14b, respectively 34a, 34b, a housing 10, respectively 30. Typically, each terminal of a power terminal block 40 comprises a clamping screw 42 cooperating with a clamping cage 43 located in the corresponding opening 44 of the terminal . When the screw 42 is tightened, the cage 43 is deformed so that it comes to grip the conductors present in the opening 44. This clamping makes it possible to make an effective electrical connection of the connection strip with any other conductor previously inserted into the opening 44, and further allows to fix the terminal block 40 against the housing of the switch device.

De plus, pour faciliter le guidage, le positionnement et le maintien des borniers de puissance 40 sur le boîtier 10, respectivement 30, d'un appareil électrique, au moins une des faces horizontales 41,49 du bornier de puissance 40 présente des organes de maintien 45. Ces organes de maintien 45 sont conçus pour pouvoir coopérer avec des moyens complémentaires aval 15a et amont 15b, respectivement 35a et 35b, agencés au niveau des plages de raccordement aval 14a et amont 14b, respectivement 34a et 34b, du boîtier.In addition, to facilitate the guiding, positioning and maintenance of the power terminal blocks 40 on the housing 10, respectively 30, of an electrical apparatus, at least one of the horizontal faces 41, 49 of the power terminal block 40 has 45. These holding members 45 are designed to cooperate with complementary downstream means 15a and upstream 15b, respectively 35a and 35b, arranged at the downstream connection areas 14a and upstream 14b, respectively 34a and 34b, of the housing.

Selon un mode de réalisation préféré, ces organes de maintien sont constitués par un ou plusieurs ergots 45 présents sur une partie avant de la face horizontale 41 du bornier de puissance 40. Lorsque le bornier de puissance 40 est monté contre un boîtier 10,30 d'un appareil, ces ergots sont introduits dans autant de cavités correspondantes 15a,15b, respectivement 35a,35b, présentes sur une partie avant des plages de raccordement 14a,14b, respectivement 34a,34b, du boîtier. Préférentiellement, ces cavités 15a,15b,35a,35b sont de forme complémentaire aux ergots 45. Une fois les barrettes de connexion engagées dans les ouvertures 44 et avant le serrage des vis 42, la mise en place définitive du bornier 40 se fait alors par glissement vers l'arrière de la face horizontale 41 le long de la plage de raccordement 14a,14b,34a,34b jusqu'en butée contre la plage d'appui 13a,13b,33a,33b. Durant cette opération, les ergots 45 sont engagés dans les cavités correspondantes 15a,15b,35a,35b contribuant au maintien et au positionnement du bornier contre le boîtier 10,30.According to a preferred embodiment, these holding members are constituted by one or more pins 45 present on a front portion of the horizontal face 41 of the power terminal block 40. When the power terminal block 40 is mounted against a housing 10, 30 d 1, these pins are introduced into as many corresponding cavities 15a, 15b, respectively 35a, 35b, present on a front portion of the connection pads 14a, 14b, respectively 34a, 34b, of the housing. Preferably, these cavities 15a, 15b, 35a, 35b are of complementary shape to the lugs 45. Once the connection bars engaged in the openings 44 and before the tightening of the screws 42, the final positioning of the terminal block 40 is then done by sliding towards the rear of the horizontal face 41 along the connection pad 14a, 14b, 34a, 34b as far as the stop against the bearing pad 13a, 13b, 33a, 33b. During this operation, the lugs 45 are engaged in the corresponding cavities 15a, 15b, 35a, 35b contributing to the maintenance and positioning of the terminal block against the housing 10,30.

Le bornier de puissance amovible 40 est avantageusement symétrique par rapport à un plan vertical médian de façon à ce qu'un même bornier 40 puisse indifféremment être monté en aval mais aussi en amont des boîtiers après retournement. Dans les exemples présentés, la face horizontale 41 comporte deux ergots 45 disposés de part et d'autre du plan vertical médian.The removable power terminal block 40 is advantageously symmetrical with respect to a median vertical plane so that a same terminal block 40 can indifferently be mounted downstream but also upstream of the boxes after reversal. In the examples presented, the horizontal face 41 has two lugs 45 disposed on either side of the median vertical plane.

En outre, le boîtier 10 représenté en figure 7 comporte en plus par construction un décrochement d'une hauteur H sur une partie avant des plages de raccordement horizontales aval 14a et amont 14b, devant les sorties des barrettes de connexion aval 19a et amont 19b. Les barrettes de connexion sont alors préférentiellement affleurantes au décrochement. Ce décrochement permet de former des plages de liaison horizontales aval 16a et amont 16b. Ces plages de liaison aval 16a et amont 16b sont donc plus éloignées de la face arrière du boîtier 10 et plus proches l'une de l'autre que les plages de raccordement aval 14a et amont 14b. Les cavités aval 15a et amont 15b sont dans ce cas placées à l'avant des plages de liaison aval 16a et amont 16b du boîtier 10, de façon à pouvoir accueillir des ergots de maintien appartenant à des éléments de liaison ou à des cales.In addition, the housing 10 shown in figure 7 further comprises by construction a recess of a height H on a front portion of the downstream horizontal connection pads 14a and upstream 14b, in front of the outputs of the downstream connection bars 19a and upstream 19b. The connection strips are then preferentially flush with the recess. This recess makes it possible to form downstream horizontal connection pads 16a and upstream 16b. These downstream 16a and 16b upstream connection pads are therefore further removed from the rear face of the housing 10 and closer to each other than the downstream 14a and upstream 14b connection pads. The downstream cavities 15a and upstream cavities 15b are in this case placed in front of the downstream 16a and upstream connection pads 16b of the casing 10, so as to be able to receive holding lugs belonging to connecting elements or wedges.

Ce décrochement sert à insérer un élément de liaison multipolaire 80 tel que celui schématisé aux figures 8 et 9. Un élément de liaison 80 se compose d'une pièce en matière isolante de forme parallélépipédique. Il possède deux faces horizontales opposées 84,86 et une face arrière 81. Des premières et secondes broches conductrices de connexion 82 et 83, qui peuvent être de section similaire aux barrettes de connexion 19 des boîtiers, sortent perpendiculairement de la première face horizontale 84, selon l'axe vertical X dans une même direction. Sur le devant de la seconde face horizontale 86, l'élément de liaison 80 comprend des ergots de maintien 85 pouvant coopérer avec cavités 15a,15b,25a,25b du boîtier 10,20. Sur la partie avant de la première face horizontale 84, l'élément de liaison 80 comprend des cavités 87 pouvant coopérer avec des ergots 45,45' de borniers de puissance 40,40'.This recess serves to insert a multipole link element 80 such as that schematically Figures 8 and 9 . A connecting element 80 consists of a piece of parallelepiped-shaped insulating material. It has two horizontal faces 84,86 and a rear face 81. First and second conductive connection pins 82 and 83, which may be of similar section to the connection strips 19 of the housings, exit perpendicularly from the first horizontal face 84, along the vertical axis X in the same direction. On the front of the second horizontal face 86, the connecting element 80 comprises holding lugs 85 which can cooperate with cavities 15a, 15b, 25a, 25b of the housing 10,20. On the front part of the first horizontal face 84, the connecting element 80 comprises cavities 87 which can cooperate with lugs 45,45 'of power terminals 40,40'.

Dans le cas d'appareils tripolaires, les premières broches 82 et les secondes broches 83 comportent donc chacune trois broches distinctes. A l'intérieur d'un élément de liaison 80, les premières broches 82 sont électriquement reliées une àune aux secondes broches 83 soit directement pôle par pôle, soit différemment suivant la fonction logique souhaitée (voir plus loin).In the case of three-pole devices, the first pins 82 and the second pins 83 thus each comprise three separate pins. Inside a connecting element 80, the first pins 82 are electrically connected to one of the second pins 83 either directly pole by pole, or differently depending on the desired logic function (see below).

La hauteur H d'un élément de liaison 80 (figure 8) est sensiblement égale àla hauteur H du décrochement correspondant au décalage entre une plage de raccordement 14a,14b et une plage de liaison 16a,16b (figure 7). De même, la profondeur d'un élément de liaison 80 est sensiblement égale à celle d'une plage de liaison 16a,16b. L'élément de liaison 80 est donc insérable entre le boîtier d'un appareil électrique et un bornier de puissance amovible. Ainsi, quand la seconde face horizontale 86 d'un élément de liaison est positionnée sur une plage de liaison 16a,16b, cet élément de liaison 80 occupe complètement l'espace créé par le décrochement, de sorte que sa première face horizontale 84 est au même niveau horizontal que la plage de raccordement 14a,14b, n'entravant pas ainsi la mise en place d'un bornier de puissance 40, mais contribuant au contraire àson maintien.The height H of a connecting element 80 ( figure 8 ) is substantially equal to the height H of the recess corresponding to the offset between a connection pad 14a, 14b and a connection pad 16a, 16b ( figure 7 ). Similarly, the depth of a connecting element 80 is substantially equal to that of a bonding pad 16a, 16b. The connecting element 80 is therefore insertable between the housing of an electrical appliance and a removable power terminal block. Thus, when the second horizontal face 86 of a connecting element is positioned on a connecting pad 16a, 16b, this connecting element 80 completely occupies the space created by the recess, so that its first horizontal face 84 is at same horizontal level as the connection range 14a, 14b, thus not impeding the establishment of a power terminal block 40, but contributing instead to its maintenance.

De plus, les broches 82,83 sont préférentiellement affleurantes àla face arrière 81 de l'élément de liaison 80, comme indiqué aux figures 2 et 9, ce qui permet, lors du positionnement d'un élément de liaison 80 dans l'ensemble, de plaquer les broches 82,83 devant les barrettes de connexion 19a, 19b, 29a, 29b. Les broches et barrettes de connexion en contact seront ensuite maintenues par serrage dans des ouvertures 44 de borniers de puissance 40.In addition, the pins 82, 83 are preferentially flush with the rear face 81 of the connecting element 80, as indicated in FIGS. Figures 2 and 9 , which makes it possible, when positioning a connection element 80 in the assembly, to press the pins 82, 83 in front of the connection strips 19a, 19b, 29a, 29b. The pins and contact strips in contact will then be clamped in openings 44 of power terminals 40.

Lorsqu'il n'y a pas d'élément de liaison 80 àpositionner sur une plage de liaison 16a,16b d'un boîtier 10, l'espace créé par le décrochement entre les plages de raccordement et de liaison peut être alors aisément rempli par une cale 70 (voir figure 10) de dimension appropriée, c'est-à-dire d'une hauteur H, d'une profondeur égale à celle de la plage de liaison et d'une largeur sensiblement égale àcelle du boîtier 10, pour améliorer le maintien d'un bornier de puissance sur le boîtier.When there is no connection element 80 to be positioned on a connection area 16a, 16b of a housing 10, the space created by the recess between the connection and connection areas can then be easily filled by a hold 70 (see figure 10 ) of appropriate size, that is to say of a height H, of a depth equal to that of the connecting range and a width substantially equal to that of the housing 10, to improve the maintenance of a power terminal on the housing.

Un ensemble de protection et de commande 5 représenté dans les figures 1 et 2 comprend trois appareils électriques interrupteurs. Cet ensemble 5 a pour but de créer un ensemble de départ moteur capable de fournir facilement et sans câblage supplémentaire une fonction logique, telle qu'une fonction inverseur (inversion du sens de marche du moteur), une fonction sélection de vitesse (commutation PV/GV : petite vitesse / grande vitesse), une fonction démarrage étoile-triangle, ou autres.A protection and control assembly 5 represented in the figures 1 and 2 includes three electrical devices switches. The purpose of this assembly 5 is to create a motor starter assembly capable of easily providing, without additional wiring, a logic function, such as an inverter function (inversion of the motor direction of operation), a speed selection function (PV / GV: low speed / high speed), a star-delta start function, or others.

Un premier appareil, comportant un boîtier 10, et un second appareil, comportant un boîtier 20 identique au boîtier 10, sont de type contacteur. Un troisième appareil, comportant un boîtier 30, est de type disjoncteur. Le premier appareil et le second appareil sont agencés l'un à côté de l'autre selon un même plan horizontal. Ils peuvent être soit juxtaposés l'un contre l'autre, soit préférentiellement légèrement espacés l'un de l'autre pour permettre l'insertion entre les deux d'un module de condamnation mécanique utilisable notamment dans le cas d'une fonction inverseur. Le troisième appareil est agencé selon un plan vertical au-dessus de l'un ou indifféremment de l'autre des deux premiers appareils.A first apparatus, comprising a housing 10, and a second apparatus, comprising a housing 20 identical to the housing 10, are of the contactor type. A third device, comprising a housing 30, is of the circuit breaker type. The first apparatus and the second apparatus are arranged next to each other in the same horizontal plane. They can be either juxtaposed against each other, or preferentially slightly spaced from each other to allow the insertion between the two of a mechanical locking module used in particular in the case of an inverter function. The third device is arranged in a vertical plane above one or indifferently the other of the first two devices.

Dans l'ensemble 5, le boîtier 30 est juxtaposé sur le boîtier 10 (mais pourrait aussi être sur le boîtier 20) selon une direction parallèle à l'axe vertical X des barrettes de connexion de telle sorte que la plage d'appui aval 33a du boîtier 30 est plaquée contre la plage d'appui amont 13b du boîtier 10. L'encombrement vertical de l'ensemble 5 est donc minimum puisque les boîtiers des appareils électriques 10,30 sont directement posés l'un sur l'autre, sans espace entre eux.In the assembly 5, the housing 30 is juxtaposed on the housing 10 (but could also be on the housing 20) in a direction parallel to the vertical axis X of the terminal strips so that the downstream support surface 33a of the housing 30 is pressed against the upstream bearing surface 13b of the housing 10. The overall size of the assembly 5 is minimal since the housings of the electrical devices 10,30 are directly placed one on the other, without space between them.

En amont de l'ensemble 5, un bornier de puissance amont 60 amovible est monté contre la plage de raccordement amont 34b du boîtier 30 du troisième appareil. Le serrage des vis du bornier amont 60 permet de fixer celui-ci contre le boîtier 30 et de raccorder électriquement les barrettes de connexion amont 39b à des conducteurs extérieurs amont. De même, en aval de l'ensemble 5, deux borniers de puissance aval 50,50' amovibles sont montés contre les plages de raccordement aval 14a, respectivement 24, des boîtiers 10, respectivement 20. Le serrage des vis de ces borniers aval 50, respectivement 50', permet de les fixer contre le boîtier 10, respectivement 20, et de raccorder électriquement leurs barrettes de connexion aval à des conducteurs extérieurs aval. Par ailleurs, un bornier de puissance 40' est placé en amont du boîtier 20 du second appareil.Upstream of the assembly 5, a removable upstream power terminal block 60 is mounted against the upstream connection zone 34b of the housing 30 of the third device. The tightening of the screws of the upstream terminal block 60 makes it possible to fix it against the housing 30 and to electrically connect the upstream connection strips 39b to upstream outer conductors. Similarly, downstream of the assembly 5, two removable 50.50 'downstream power terminals are mounted against the downstream connection pads 14a, respectively 24, of the housings 10, respectively 20. The tightening of the screws of these downstream terminal blocks 50 , respectively 50 ', makes it possible to fix them against the housing 10, respectively 20, and to electrically connect their downstream connection bars to downstream outside conductors. In addition, a power terminal block 40 'is placed upstream of the housing 20 of the second apparatus.

Le décalage existant entre la plage d'appui et la plage de raccordement d'une même face horizontale de tous les boîtiers est conçu pour que, lorsque le boîtier 30 du troisième appareil est juxtaposé sur le boîtier 10 du premier appareil par leur plage d'appui, l'espace existant entre la plage de raccordement aval 34a du boîtier 30 et la plage de raccordement amont 14b du boîtier 10 permette de loger un bornier de puissance amovible 40 commun aux boîtiers 30 et 10. Les ergots de maintien 45 de ce bornier de puissance commun 40 sont associés indifféremment soit aux cavités 35a,35b du boîtier 30, soit aux cavités 15a,15b du boîtier 10. Ce bornier commun 40 permet de raccorder électriquement les barrettes de connexion aval 39a du boîtier 30 avec les barrettes de connexion amont 19b du boîtier 10, mais permet aussi la fixation des boîtiers 30 et 10 entre eux.The difference between the support range and the connection area of the same horizontal face of all the housings is designed so that, when the housing 30 of the third device is juxtaposed on the housing 10 of the first device by their range of support, the space existing between the downstream connection range 34a of the housing 30 and the upstream connection zone 14b of the housing 10 can accommodate a removable power terminal block 40 common to the housings 30 and 10. The holding lugs 45 of this terminal block of common power 40 are associated either with the cavities 35a, 35b of the housing 30, or with the cavities 15a, 15b of the housing 10. This common terminal block 40 makes it possible to electrically connect the downstream connection bars 39a of the housing 30 with the upstream connection strips. 19b of the housing 10, but also allows the fixing of the housings 30 and 10 between them.

Pour assurer efficacement ce raccordement électrique, les barrettes aval 39a du boîtier 30 du troisième appareil sont légèrement décalées par rapport aux barrettes amont 19b du boîtier 10 du premier appareil suivant une direction perpendiculaire àl'axe vertical X des barrettes. Dans les exemples schématisés, les barrettes aval 39a du boîtier 30 sont décalées vers l'arrière par rapport aux barrettes amont 19b du boîtier 10 (voir figure 2). Ce décalage est suffisant pour ne pas gêner la juxtaposition des boîtiers 10 et 30 lors du montage de l'ensemble 5, mais permet néanmoins, une fois les vis 42 du bornier commun 40 serrées, que les barrettes aval 39a du troisième appareil se chevauchent et soient affleurantes avec les barrettes amont 19b du premier appareil de manière à former une zone de contact électrique suffisante, conforme au courant électrique susceptible de circuler dans l'ensemble de protection et de commande 5.To effectively provide this electrical connection, the downstream strips 39a of the housing 30 of the third device are slightly offset from the upstream strips 19b of the housing 10 of the first device in a direction perpendicular to the vertical axis X of the bars. In the diagrammatic examples, the downstream bars 39a of the housing 30 are offset rearwardly with respect to the upstream strips 19b of the housing 10 (see FIG. figure 2 ). This offset is sufficient not to hinder the juxtaposition of the housings 10 and 30 during assembly of the assembly 5, but nevertheless allows, once the screws 42 of the common terminal block 40 tight, that the downstream bars 39a of the third device overlap and are flush with the upstream strips 19b of the first device so as to form a sufficient electrical contact area, in accordance with the electric current likely to flow in the protection and control assembly 5.

Avantageusement, le bornier commun 40 ainsi que les borniers de puissance 40',50,50' et 60, sont tous identiques au bornier de puissance amovible 40 décrit précédemment. Cela réduit ainsi le nombre de pièces différentes nécessaires au montage de l'ensemble 5 puisque tous les borniers de puissance sont interchangeables entre eux. Ils comprennent des ergots de maintien 45,55,65 coopérant avec les cavités de forme complémentaire des boîtiers 10,20,30 de façon à faciliter le guidage, le positionnement et le maintien des borniers contre les boîtiers des appareils électriques.Advantageously, the common terminal block 40 and the power terminals 40 ', 50, 50' and 60, are all identical to the removable power terminal block 40 described above. This reduces the number of different parts needed to mount the assembly 5 since all the power terminal blocks are interchangeable with each other. They comprise holding lugs 45, 55, 65 cooperating with the cavities of complementary shape of the housings 10, 20, 30 so as to facilitate the guiding, the positioning and the maintenance of the terminal blocks against the housings of the electrical appliances.

Dans l'ensemble 5 des figures 1 et 2, les boîtiers 10 et 20 sont reliés entre eux par un élément de liaison amont 80 et un élément de liaison aval 80' multipolaires de manière à réaliser par exemple une fonction inverseur. L'élément de liaison amont 80 est inséré dans les plages de liaison amont des boîtiers 10 et 20 de telle sorte que les premières broches 82 de l'élément de liaison amont 80 sont en contact avec les barrettes amont 19b du boîtier 10 et les secondes broches 83 de l'élément de liaison amont 80 sont en contact avec les barrettes amont 29b du boîtier 20. Conformément aux figures 2 et 5, le bornier commun 40 permet donc de serrer ensemble les broches 82, les barrettes amont 19b du boîtier 10 et les barrettes aval 39a du boîtier 30. Le bornier 40' permet lui de serrer ensemble les broches 83 et les barrettes amont 29b du boîtier 20.Overall 5 figures 1 and 2 the housings 10 and 20 are interconnected by an upstream connecting element 80 and a multipolar downstream connecting element 80 'so as to provide, for example, an inverter function. The upstream link element 80 is inserted into the upstream link regions of the boxes 10 and 20 so that the first pins 82 of the upstream link element 80 are in contact with the upstream strips 19b of the box 10 and the second pins 83 of the upstream connecting element 80 are in contact with the upstream strips 29b of the housing 20. In accordance with figures 2 and 5 , the common terminal block 40 thus makes it possible to clamp together the pins 82, the upstream strips 19b of the casing 10 and the downstream strips 39a of the casing 30. The terminal block 40 'allows it to clamp together the pins 83 and the upstream strips 29b of the casing 20 .

L'élément de liaison aval 80' est inséré dans les plages de liaison aval des boîtiers 10 et 20. Les premières broches de l'élément de liaison aval 80' sont donc en contact avec les barrettes aval 19a du boîtier 10 et serrées ensemble par le bornier 50. Les secondes broches de l'élément de liaison aval 80' sont en contact avec les barrettes aval 29a du boîtier 20 et serrées ensemble par le bornier 50'.The downstream connecting element 80 'is inserted into the downstream connection areas of the housings 10 and 20. The first pins of the downstream connection element 80' are therefore in contact with the downstream strips 19a of the housing 10 and clamped together by the terminal 50. The second pins of the downstream connecting element 80 'are in contact with the downstream bars 29a of the housing 20 and clamped together by the terminal block 50'.

Le câblage interne des broches de connexion à l'intérieur des éléments de liaison 80,80' permet de réaliser une fonction logique. Pour une fonction inverseur réalisée avec des appareils tripolaires, l'élément de liaison amont 80 comporte un premier pôle des premières broches 82 qui est relié en interne au même pôle correspondant des secondes broches 83, alors que les deux autres pôles des premières broches 82 sont reliés en interne de façon inversée aux pôles correspondants des secondes broches 83. Par contre, les pôles des premières et secondes broches de l'élément de liaison aval 80' sont reliés en interne directement un à un.The internal wiring of the connection pins inside the connecting elements 80,80 'makes it possible to perform a logic function. For an inverter function performed with three-pole devices, the upstream link element 80 has a first pole of the first pins 82 which is internally connected to the same corresponding pole of the second pins 83, while the other two poles of the first pins 82 are inversely connected internally to the corresponding poles of the second pins 83. On the other hand, the poles of the first and second pins of the downstream link element 80 'are connected internally directly one by one.

Grâce à cette disposition avantageuse des éléments de liaison 80,80', l'ensemble 5 est extrêmement simple à réaliser et ne présente pas un encombrement supérieur (entraxe, hauteur, profondeur) à celui d'un ensemble standard de trois appareils électriques ne comprenant pas de tels éléments de liaison. L'ensemble 5 peut donc aisément s'intégrer dans un coffret ou armoire existant avec d'autres appareils électriques.With this advantageous arrangement of the connecting elements 80,80 ', the assembly 5 is extremely simple to perform and does not have a larger footprint (center distance, height, depth) than a standard set of three electrical appliances not including no such connecting elements. The assembly 5 can therefore easily integrate into an existing cabinet or cabinet with other electrical appliances.

On peut aussi concevoir un ensemble de protection et de commande similaire à l'ensemble 5 mais comportant uniquement un seul élément de liaison amont 80 dont les broches 82,83 sont reliées en interne directement pôle à pôle, sans élément de liaison aval 80'. Cet ensemble permet alors d'alimenter deux contacteurs 10,20 àpartir d'un même disjoncteur amont 30, pour une utilisation en commutation PV/GV, par exemple. L'élément de liaison aval 80' absent peut être remplacé par deux cales 70 entre le boîtier 20 et le bornier 50, et entre le boîtier 30 et le bornier 50'.It is also possible to design a protection and control assembly similar to the assembly 5 but comprising only a single upstream link element 80 whose pins 82, 83 are internally connected directly pole to pole, without a downstream link element 80 '. This assembly then makes it possible to supply two contactors 10, 20 from a same upstream circuit breaker 30, for use in PV / GV switching, for example. The downstream link element 80 'can be replaced by two shims 70 between the housing 20 and the terminal block 50, and between the housing 30 and the terminal block 50'.

La figure 10 montre un autre exemple d'ensemble de protection et de commande conforme à l'invention. Cet ensemble 6 comprend un premier appareil 30, par exemple de type disjoncteur, et un second appareil 10, par exemple de type contacteur, placé à côté du premier appareil 10. L'ensemble 6 comprend un bornier amovible amont 60 permettant de raccorder les barrettes de connexion amont 39b du boîtier 30 du premier appareil avec des conducteurs extérieurs amont. L'ensemble 6 comprend également un bornier amovible aval 50 permettant de raccorder les barrettes de connexion aval 19a du boîtier 10 du second appareil avec des conducteurs extérieurs aval. Les boîtiers 10 et 30 sont reliés électriquement entre eux par un élément de liaison série 90 en forme de S (voir figure 11), comportant une partie centrale 91 située entre deux parties horizontales desquelles sortent des premières broches de connexion 92 et des secondes broches de connexion 93, selon un axe vertical, mais dans une direction opposée. A l'intérieur de l'élément 90, les broches 92 et 93 sont reliées entre elles en direct pôle par pôle.The figure 10 shows another example of a protection and control assembly according to the invention. This assembly 6 comprises a first device 30, for example of the circuit-breaker type, and a second device 10, for example of the contactor type, placed next to the first device 10. The assembly 6 comprises an upstream removable terminal block 60 for connecting the strips 39b upstream connection of the housing 30 of the first device with upstream outer conductors. The assembly 6 also includes a removable terminal block 50 for connecting the downstream connection strips 19a of the housing 10 of the second device with downstream outer conductors. The housings 10 and 30 are electrically interconnected by an S-shaped series link member 90 (see FIG. figure 11 ), having a central portion 91 located between two horizontal portions from which first connecting pins 92 and second connecting pins 93 extend, along a vertical axis, but in an opposite direction. Inside the element 90, the pins 92 and 93 are interconnected in direct pole by pole.

Les premières broches 92 sont maintenues en contact avec les barrettes aval 39a du boîtier 30 grâce à un bornier amovible 60' et les secondes broches 93 sont maintenues en contact avec les barrettes amont 19b du boîtier 10 grâce à un bornier amovible 50'. Les borniers de puissance 50,50',60,60' sont identiques et interchangeables. Ainsi, l'ensemble 6 permet de réaliser rapidement une association en série de deux appareils électriques (par exemple un disjoncteur / contacteur) situés l'un àcôté de l'autre sans nécessiter de câblage particulier. Les boîtiers 10 et 30 ne sont pas plaqués l'un contre l'autre, de façon àautoriser l'insertion de la partie centrale 91 de l'élément de liaison 90 entre les deux. La largeur de la partie centrale 91 est par exemple sensiblement égale à la largeur d'un module de condamnation mécanique utilisable entre deux contacteurs, de façon à standardiser les écarts entre deux appareils électriques situés l'un àcôté de l'autre.The first pins 92 are held in contact with the downstream bars 39a of the housing 30 through a removable terminal block 60 'and the second pins 93 are held in contact with the upstream strips 19b of the housing 10 through a removable terminal block 50'. Power terminals 50,50 ', 60,60' are identical and interchangeable. Thus, the assembly 6 makes it possible to quickly achieve a series association of two electrical devices (for example a circuit breaker / contactor) located next to each other without requiring special wiring. The housings 10 and 30 are not pressed against each other, so as to allow the insertion of the central portion 91 of the connecting element 90 between the two. The width of the central portion 91 is for example substantially equal to the width of a mechanical locking module used between two contactors, so as to standardize the differences between two electrical devices located next to each other.

Avantageusement, cette disposition permet de réaliser aisément la connexion et le montage de l'ensemble 6, même lorsque les boîtiers 10 et 30 des appareils sont préalablement montés sur leur support, châssis, profilé ou platine. En effet, l'élément de liaison 90 peut se monter alors par la face avant de l'ensemble et se positionner grâce à des ergots de maintien, avant que les différents borniers de puissance soient ensuite positionnés et vissés pour obtenir l'ensemble 6.Advantageously, this arrangement makes it easy to connect and assemble the assembly 6, even when the housings 10 and 30 of the devices are previously mounted on their support, frame, profile or platinum. Indeed, the connecting element 90 can then be mounted by the front face of the assembly and position with holding pins, before the various power terminals are then positioned and screwed to obtain the assembly 6.
