Definitions
- the present invention relates to the field of unitary modular electrical protection products of the switch, circuit breaker, differential block, switch and differential circuit breaker type, etc.
- This known distribution function is generally carried out by one or more rigid conductors connecting the upstream connection terminals of the electrical devices to the same potential. This or these conductors then extend in their quasi-integrity outside the electrically connected devices, the devices being held on a rail called "modular rail" well known to those skilled in the art.
- Certain groupings of products are requested by customers for faster and standardized installation of these devices in the electrical panel.
- each electrical appliance is arranged in a truncated box and is connected to the removable block which main function is to ensure the compatibility of the bridging step between products of an existing installation and truncated products whose modular step constraint does not need to be respected.
- This configuration has several drawbacks.
- the modular devices must be truncated on the one hand, this does not make it possible to use all the space offered by the normal dimension of a modular apparatus, the area allocated to the removable block being "lost".
- the removable block is individually connected to each truncated modular device, which does not ensure a mechanical unit of the assembly. This mechanical non-unity of the assembly can be problematic when the block thus formed is connected to cables of large section which exert significant forces on the truncated modular products or during the transport of a complete assembled block.
- the volume available for the passage of these conductors is reduced or almost nonexistent.
- the passage of conductors of different potentials for example the passage of a phase conductor and a neutral conductor, imposes a specific distance in the air between the active parts of these conductors in order to avoid short -circuit between these two conductors, which has the impact of increasing the volume necessary for their passage.

- the mechanical and electrical connection system integrates the fixing function into a set of different electrical devices to which it must distribute an electrical potential.
- the system is at least partly contained in the volume defined by the electrical devices in order to exceed as little as possible the volume defined by the two devices and therefore to allow the installing electrician to have more volume at the exterior of the devices with a conventional bridging system. This is possible because the two functions, potential distribution and fixing of the devices are included in the same mechanical and electrical connection system.

- each of the input connection terminals may have only one type of connection for cable or bridging comb or may be of the spring type and not of the screw type, all combinations being possible.
- the assembly having the following particularity: the four input connection terminals extend over the entire surface Inf of the assembly constituted by the assembly of the various housings. So on the figure 7 , the connection points E11, E21, E31, E41 extend regularly spaced over the entire lower surface inf of said block. Thus the electrician operator has all this surface in order to be able to connect the various input connection terminals of said differential device to the electrical network. In addition, the input connection terminals being distributed over this entire surface, the maximum size of each conductor to be connected is thus optimized.
- each sleeve M can preferably be positioned in a barrel F made of insulating materials of the plastic type.
- this barrel has a generally hollow cylindrical shape.
- the mechanical connection system is produced by the screw 102, the rod 100 in combination with parts of the housings of the electrical devices constituting said assembly.
- the row of boxes has two end boxes, the first one to the left of the figure 8 and a second on the right of this same figure, opposite the first.
- the screw 102 screwed into the rod 100 comes to bear on a wall 120 of the housing located on the left on the figure 8
- the other end of the rod 100 comprises a head 101 which comes to bear on a wall 121 of the housing located on the right on the figure 8 and opposite the first case cited.
- the pressure generated by this assembly makes it possible to clamp between them all the housings included between the two end housings in a row in which their large faces are joined.
- two adjacent electrical devices for example the two circuit breakers contained in the boxes 2 and 2 ', are separated by a joint part (Int).
- This joint part includes the large consecutive parallel faces and facing these two housings 2 and 2 'in the row of the assembly.
- the two consecutive large parallel faces of these two consecutive boxes 2, 2 ′ of the row of the set being integrated in this adjoining room, the two consecutive and adjacent electrical devices are no longer separated by a double wall, which saves material.
- the Int part can also be positioned between the 2 'and 2 "boxes.
- the two consecutive large parallel faces of these two devices are integrated in this part.
- the figure 12 shows a partial perspective view of an assembly according to an embodiment of the invention from a viewing angle which allows the head of the screw 102 to be seen.
- This screw is accessible through a cylindrical hole 105 opening into a side wall of one of the boxes of the assembly.
- This hole allows, during the assembly of the mechanical and electrical connection system according to the embodiment, to access the head of the screw 102, this in order to carry out the screwing of the screw 102 on the rod 100.
- the hole cylindrical 105 ends with a counterbore which allows the head of the screw 102 to be supported on an end box of the assembly.
- the screw 102 being in contact with the rod 100 which distributes an electrical potential, it is therefore itself at the same electrical potential as that of the rod 100.
- the head of the screw 102 is therefore accessible to a user and presents a risk of electric shock when the apparatuses of the assembly are in service.
- One possible solution is to offset the counterbore from the bottom of the hole 105 so that the head of the screw is no longer accessible by the user's finger. In this case the head of the screw 102 remains always visible to the user and he is protected.
- Another option is the one shown in the figures 13 and 14 .
- the hole 105 is surrounded by a surface 106 parallel to the face of the housing and offset from the latter so as to allow the installation of a shutter 107. Thanks to this surface offset, the surface 106 is set back by relative to the lateral face of the housing, once in place the shutter 107 is flush with the lateral surface of the housing and is thus almost invisible and does not affect the dimension of the row of boxes as can be seen in the figure 14 .
- the shutter has a rectangular shape, the shape of the shutter has no influence on its function from the moment its surface covers the through hole 105.

Description
La présente invention concerne le domaine des produits de protection électriques modulaires unitaires de type interrupteurs, disjoncteurs, blocs différentiels, interrupteur et disjoncteurs différentiels etc...The present invention relates to the field of unitary modular electrical protection products of the switch, circuit breaker, differential block, switch and differential circuit breaker type, etc.
Ces produits peuvent de par leur conception modulaire s'assembler pour offrir un panel de combinaisons de fonctions en un seul appareil dit multi-modulaire permettant de répondre aux différentes normes d'installations électriques.Due to their modular design, these products can be assembled to offer a range of combinations of functions in a single so-called multi-modular device enabling the various standards of electrical installations to be met.
Dans l'assemblage ou le regroupement de produits de protection de type modulaire, il peut être nécessaire de distribuer l'alimentation d'une phase ou du neutre à l'entrée des différents appareils.When assembling or grouping modular type protection products, it may be necessary to distribute the supply of one phase or neutral to the input of the various devices.
Cette fonction de distribution connue est généralement réalisée par un ou des conducteurs rigides reliant les bornes de connexion amont des appareils électrique au même potentiel. Ce ou ces conducteurs d'étendent alors dans leur quasi intégrité à l'extérieur des appareils électriquement reliés, les appareils étant maintenu sur un rail dit « rail modulaire » bien connu de l'homme de l'art.This known distribution function is generally carried out by one or more rigid conductors connecting the upstream connection terminals of the electrical devices to the same potential. This or these conductors then extend in their quasi-integrity outside the electrically connected devices, the devices being held on a rail called "modular rail" well known to those skilled in the art.
Certains regroupements de produits sont demandés par les clients en vue d'une installation plus rapide et standardisée de ces appareils dans le tableau électrique.Certain groupings of products are requested by customers for faster and standardized installation of these devices in the electrical panel.
Dans le cas où le constructeur assure lui-même cette distribution de potentiel, il peut être intéressant alors de l'intégrer dans le volume délimité par les produits et ce dans un double objectif de gain de place et de gain de coût.In the case where the manufacturer himself distributes this potential, it may then be advantageous to integrate it into the volume delimited by the products, with the dual objective of saving space and saving cost.
Lorsque le regroupement touche des produits dans lesquels la fonction principale n'occupe pas la totalité du volume du produit modulaire, comme dans le cas des interrupteurs par exemple qui ne comportent que des contacts, un mécanisme d'ouverture et de fermeture de ces contacts et des bornes de connexion d'entrée et de sortie, il est aisé de trouver un volume dans lequel la distribution amont du courant peut être positionnée. C'est le cas dans le document
Document
Lorsque le regroupement touche des produits plus complexes, le volume disponible pour le passage de ces conducteurs est diminué voire quasi inexistant. De plus, le passage de conducteurs de potentiels différents, par exemple le passage d'un conducteur de phase et d'un conducteur de neutre, impose une distance spécifique dans l'air entre les parties actives de ces conducteurs afin d'éviter le court-circuit entre ces deux conducteur, qui a pour impact d'augmenter le volume nécessaire à leur passage.When the grouping affects more complex products, the volume available for the passage of these conductors is reduced or almost nonexistent. In addition, the passage of conductors of different potentials, for example the passage of a phase conductor and a neutral conductor, imposes a specific distance in the air between the active parts of these conductors in order to avoid short -circuit between these two conductors, which has the impact of increasing the volume necessary for their passage.
L'invention a pour but de résoudre ce problème, à savoir dans un regroupement d'appareils modulaires de type disjoncteur, interrupteur différentiel etc... comment distribuer au moins un même potentiel entre des bornes d'entrée et/ou de sortie des appareils constituants le regroupement dans le volume défini par les appareils modulaires tout en assurant l'intégrité mécanique du bloc ainsi constitué.The object of the invention is to solve this problem, namely in a grouping of modular devices of the circuit breaker, differential switch, etc. type, how to distribute at least the same potential between input and / or output terminals of the devices. constituents grouping in the volume defined by the modular devices while ensuring the mechanical integrity of the block thus formed.
Ce problème est résolu par l'invention et plus particulièrement par un ensemble comprenant une rangée d'au moins deux boîtiers isolants distincts présentant chacun deux grandes faces parallèles et comportant chacun au moins un appareil électrique modulaire par exemple de type disjoncteur, interrupteur, bloc différentiel, chacun desdits appareils électriques comprenant au moins une borne de connexion électrique, caractérisé en ce que ledit ensemble comprend au moins un système de liaison mécanique et électrique reliant mécaniquement lesdits boîtiers entre eux en exerçant en outre un effort presseur, sensiblement perpendiculaire aux deux grandes faces parallèles sur deux boîtiers de la rangée, et en ce que ledit système relie électriquement la ou l'une des borne(s) d'au moins un appareil électrique avec la ou l'une des borne(s) d'un autre appareil électrique afin de distribuer un potentiel électrique entre celles-ci,
et en ce que ledit système est au moins en partie contenu dans le volume défini par les boîtiers.This problem is solved by the invention and more particularly by an assembly comprising a row of at least two separate insulating boxes each having two large parallel faces and each comprising at least one modular electrical appliance, for example of the circuit breaker, switch, differential block type. , each of said electrical devices comprising at least one electrical connection terminal, characterized in that said assembly comprises at least one mechanical and electrical connection system mechanically connecting said boxes between them by also exerting a pressing force, substantially perpendicular to the two large parallel faces on two housings of the row, and in this that said system electrically connects the or one of the terminal (s) of at least one electrical appliance with the or one of the terminal (s) of another electrical appliance in order to distribute an electrical potential therebetween,
and in that said system is at least partly contained in the volume defined by the housings.
Ce lien mécanique entre deux boîtiers de la rangée permet d'assurer le maintien mécanique de tous les appareils électriques modulaires assemblés par le système de liaison mécanique et électrique en un ensemble mécaniquement stable. Un appareil électrique donné du bloc ainsi constitué, ne peut être désassemblé du dit bloc en une simple opération. De plus, même lorsque l'ensemble n'est pas assemblé sur un rail de type « rail modulaire » l'ensemble des appareils se comporte comme un bloc unitaire, l'ensemble est mécanique en un seul composant.This mechanical link between two boxes in the row ensures the mechanical maintenance of all modular electrical devices assembled by the mechanical and electrical connection system in a mechanically stable assembly. A given electrical appliance of the block thus formed cannot be disassembled from the said block in a simple operation. In addition, even when the assembly is not assembled on a rail of the “modular rail” type, the set of devices behaves like a unitary block, the assembly is mechanical in a single component.
Ainsi le système de liaison mécanique et électrique intègre la fonction de fixation en un ensemble des différents appareils électriques auxquels il doit distribuer un potentiel électrique. De plus, le système est au moins en partie contenu dans le volume défini par les appareils électriques afin de dépasser le moins possible du volume défini par les deux appareils et donc de permettre à l'électricien installateur de disposer de plus de volume à l'extérieur des appareils qu'avec un système de pontage classique. Ceci est possible du fait que les deux fonctions, distribution de potentiel et fixation des appareils sont comprises dans le même système de liaison mécanique et électrique.Thus the mechanical and electrical connection system integrates the fixing function into a set of different electrical devices to which it must distribute an electrical potential. In addition, the system is at least partly contained in the volume defined by the electrical devices in order to exceed as little as possible the volume defined by the two devices and therefore to allow the installing electrician to have more volume at the exterior of the devices with a conventional bridging system. This is possible because the two functions, potential distribution and fixing of the devices are included in the same mechanical and electrical connection system.
De préférence les appareils modulaires sont « entiers », c'est-à-dire qu'ils s'étendent dans le volume défini par la norme UTE C 61-920. Ils ne sont pas tronqués afin de permettre le passage d'un quelconque système de pontage dans leur volume.Preferably the modular devices are "whole", that is to say that they extend within the volume defined by the standard UTE C 61-920. They are not truncated in order to allow the passage of any bridging system in their volume.
Préférentiellement, cet ensemble comprend une rangée d'au moins deux boîtiers isolants distincts se caractérisé en ce que ladite rangée comporte deux boîtiers d'extrémité à savoir un premier boîtier d'extrémité à une extrémité de la rangée et un deuxième boîtier d'extrémité à l'autre extrémité de la rangée, ledit système de liaison mécanique et électrique relie mécaniquement lesdits boîtiers entre eux en exerçant en outre un effort presseur, sensiblement perpendiculaire aux deux grandes faces parallèles sur les boîtiers d'extrémités. De ce fait l'effort presseur s'exerce de l'extérieur vers l'intérieur dans l'ensemble de boîtiers de la rangée, ceci afin d'assurer une meilleure cohésion de l'ensemble de boîtiers.Preferably, this assembly comprises a row of at least two separate insulating housings characterized in that said row comprises two end housings, namely a first end housing at one end of the row and a second end housing at the other end of the row, said mechanical and electrical connection system mechanically connects said boxes to each other by exerting a pressing force, substantially perpendicular to the two large parallel faces on the end boxes. As a result, the pressing force is exerted from the outside towards the inside in the set of boxes in the row, this in order to ensure better cohesion of the set of boxes.
Préférentiellement le système de liaison mécanique et électrique est entièrement contenu dans le volume défini par les boîtiers. Ceci afin de permettre à l'électricien installateur de disposer d'un volume à l'extérieur des appareils maximal comparativement avec un système de pontage classique.Preferably, the mechanical and electrical connection system is entirely contained in the volume defined by the boxes. This is to allow the installing electrician to have a maximum volume outside the devices compared to a conventional bridging system.
Optionnellement l'ensemble peut contenir des appareils électriques du type auxiliaire qui ne possède qu'une seule borne de connexion électrique. Ce type d'appareil est en particulier destiné à communiqué à l'utilisateur une information mesurée sur la ligne électrique par le biais de leur unique connexion électrique. Ce type d'appareil peut optionnellement ne pas être muni de borne électrique, par exemple s'il contient un capteur de type capteur de courant sans contact.Optionally, the assembly can contain electrical devices of the auxiliary type which has only one electrical connection terminal. This type of device is in particular intended to communicate to the user information measured on the electrical line by means of their single electrical connection. This type of device may optionally not be fitted with an electrical terminal, for example if it contains a sensor of the contactless current sensor type.
Préférentiellement, l'ensemble est caractérisé en ce que chacun desdits appareils électriques comprend au moins une borne de connexion électrique d'entrée et au moins une borne de connexion électrique de sortie le système de liaison mécanique et électrique reliant électriquement au moins une borne de connexion de sortie d'au moins un premier appareil électrique à au moins une borne de connexion d'entrée d'au moins un autre appareil électrique. C'est-à-dire que la ou les borne(s) de connexion(s) électrique(s) sont réalisée(s) sous la forme de borne(s) de connexion(s) électrique(s) d'entrée et/ou sous la forme de borne(s) de connexion(s) électriques de sortie. Préférentiellement, si l'un des appareils électriques est un appareil de type différentiel, et qu'il est destiné à être assemblé à au moins un appareil de type interrupteur, disjoncteur etc.., l'ensemble permet de relier électriquement la borne de connexion électrique de sortie du premier appareil à la borne de connexion électrique d'entrée l'autre appareil, ou aux entrées des autres appareils. Ainsi le schéma électrique de distribution du potentiel est conforme à ce que demandent les normes d'installation et de plus le système de liaison électrique et mécanique permet l'assemblage mécanique des différents appareils.Preferably, the assembly is characterized in that each of said electrical devices comprises at least one electrical input connection terminal and at least one electrical output connection terminal the mechanical and electrical connection system electrically connecting at least one connection terminal output of at least one first electrical device to at least one input connection terminal of at least one other electrical device. That is to say that the terminal (s) of electrical connection (s) are made (s) in the form of terminal (s) of electrical connection (s) input and / or in the form of electrical connection terminal (s) for output. Preferably, if one of the electrical devices is a device of the differential type, and it is intended to be assembled with at least one device of the switch, circuit breaker type, the assembly makes it possible to connect the connection terminal electrically. output from the first device to the electrical input connection terminal of the other device, or to the inputs of other devices. Thus the electrical diagram of potential distribution is in accordance with what the installation standards require and moreover the electrical and mechanical connection system allows the mechanical assembly of the various devices.
Préférentiellement, l'ensemble se caractérise par le fait que le système de liaison mécanique et électrique relie électriquement au moins deux bornes de connexion électriques d'entrée d'au moins deux appareils électriques. Préférentiellement si les au moins deux appareils à relier électriquement sont du type disjoncteur, interrupteur etc..., l'ensemble permet de relier électriquement les bornes de connexion d'entrée des appareils entre elles au même potentiel. Ainsi le schéma électrique de distribution du potentiel est conforme à ce que demandent les normes d'installation et de plus le système de liaison électrique et mécanique permet l'assemblage mécanique des différents appareils.Preferably, the assembly is characterized in that the mechanical and electrical connection system electrically connects at least two electrical connection terminals for input of at least two electrical devices. Preferably if the at least two devices to be electrically connected are of the circuit breaker, switch etc ... type, the assembly makes it possible to electrically connect the input connection terminals of the devices to each other at the same potential. So the electrical diagram of distribution of the potential complies with what the installation standards require and moreover the electrical and mechanical connection system allows the mechanical assembly of the various devices.
Préférentiellement, l'ensemble se caractérise en ce que le système de liaison mécanique et électrique comprend une tige transversale, chacune des bornes de connexion électrique et/ou bornes de connexion électrique d'entrée et/ou de sortie d'au moins un appareil électrique de l'ensemble comprenant un connecteur interne au(x)dit(s) boîtier(s), la tige étant apte à être connectée aux connecteurs électriques à l'intérieur des boitiersPreferably, the assembly is characterized in that the mechanical and electrical connection system comprises a transverse rod, each of the electrical connection terminals and / or electrical input and / or output connection terminals of at least one electrical appliance. of the assembly comprising an internal connector to the said housing (s), the rod being able to be connected to the electrical connectors inside the housings
Ainsi la distribution du potentiel se fait dans le volume des boîtiers des appareils et n'occupe pas d'espace à l'extérieur de ce volume. De ce fait l'électricien installateur dispose d'un espace maximal à l'extérieur de l'ensemble ainsi constitué. Le fait que cette tige soit transversale aux appareils permet de relier tous les appareils électriques concernés. La distribution du potentiel à chaque appareil se fait par l'intermédiaire d'une liaison électrique à la tige transversale, préférentiellement par des connecteurs. Cette liaison peut être aussi réalisée par brasage d'un conducteur sur le système de liaison mécanique et électrique et plus particulièrement sur la tige transversale ou sur une partie spécifique de celle-ci. Le connecteur peut également être brasé sur la tige transversale ou sur une partie spécifique de celle-ci. Préférentiellement le connecteur est fixe par rapport au(x) dit(s) boîtier(s), ceci afin de permettre un meilleur enfichage de la tige dans le connecteur. Cependant ces connecteurs peuvent également être mobiles par rapport au(x) dit(s) boîtier(s) si l'assemblage tige-connecteur nécessite un mouvement relatif du connecteur par rapport au(x) dit(s) boîtier(s).Thus the distribution of the potential is done in the volume of the housings of the devices and does not occupy space outside this volume. As a result, the installing electrician has maximum space outside the assembly thus formed. The fact that this rod is transverse to the devices makes it possible to connect all the electrical devices concerned. The potential is distributed to each device via an electrical connection to the transverse rod, preferably by connectors. This connection can also be achieved by brazing a conductor on the mechanical and electrical connection system and more particularly on the transverse rod or on a specific part thereof. The connector can also be soldered on the transverse rod or on a specific part thereof. Preferably, the connector is fixed relative to the said housing (s), this in order to allow better insertion of the rod into the connector. However, these connectors can also be movable relative to the said housing (s) if the rod-connector assembly requires relative movement of the connector with respect to the said housing (s).
Préférentiellement, l'ensemble se caractérise également par le fait qu'au moins l'un des connecteurs est constitué d'un manchon conducteur d'allure cylindrique comportant au moins une zone expansible vers l'extérieur sous l'action de la tige transversale au moment de son insertion dans le manchon. Ainsi l'insertion de la tige dans le manchon est possible et la connexion se fait automatiquement au moment de l'insertion, cette zone assurant un effort de contact entre la tige transversale et le manchon conducteur. Préférentiellement, ledit manchon est également doté d'une excroissance extérieure d'allure radiale fixée à une borne d'entrée ou de sortie d'un des appareils électriques, cette excroissance facilite la connexion au circuit électrique de l'appareil électrique à connecter à la tige transversale.Preferably, the assembly is also characterized by the fact that at least one of the connectors consists of a conductive sleeve of cylindrical appearance comprising at least one zone that expands outward under the action of the transverse rod at the when inserted into the sleeve. Thus the insertion of the rod into the sleeve is possible and the connection is made automatically at the time of insertion, this zone ensuring a contact force between the transverse rod and the conductive sleeve. Preferably, said sleeve is also provided with an external protuberance of radial appearance fixed to an input or output terminal of one of the electrical appliances, this protrusion facilitates the connection to the electrical circuit of the electrical device to be connected to the cross rod.
Avantageusement, chaque zone expansible est constituée entre deux fentes d'allure axiale pratiquées dans la paroi périphérique du manchon. Cette réalisation permet d'optimiser la longueur de chaque zone expansible, donc d'optimiser la quantité de matière nécessaire à la réalisation du dit manchon. Préférentiellement cette fente est pratiquée à partir d'une des extrémités du manchon.Advantageously, each expandable zone is formed between two axial-shaped slots made in the peripheral wall of the sleeve. This embodiment makes it possible to optimize the length of each expandable zone, therefore to optimize the amount of material necessary for the production of said sleeve. Preferably, this slot is made from one of the ends of the sleeve.
De préférence, l'une des fentes d'allure axiale est pratiquée jusqu'à déboucher à l'autre extrémité du manchon, l'excroissance extérieure étant d'un seul tenant avec l'un des bords de ladite fente. Cette configuration permet la réalisation du manchon et de l'excroissance extérieure selon une géométrie qui permet la mise à plat de ces deux parties du système. Cette mise à plat est nécessaire à la fabricabilité du manchon et de l'excroissance extérieure d'un seul tenant. Ainsi, grâce à cette disposition, le manchon peut être fabriqué par enroulage autour d'un noyau tout en étant initialement rattaché à l'excroissance. Préférentiellement, le manchon est réduit à sa plus simple expression de tube cylindrique ou d'allure tronconique et l'excroissance extérieure est reportée sur la borne d'entrée ou de sortie à connecter au manchon. Préférentiellement, cette borne est directement liée au manchon.Preferably, one of the axial-looking slots is made until it opens at the other end of the sleeve, the external projection being in one piece with one of the edges of said slot. This configuration allows the realization of the sleeve and the outer protrusion according to a geometry which allows the flattening of these two parts of the system. This flattening is necessary for the manufacture of the sleeve and of the external protuberance in one piece. Thus, thanks to this arrangement, the sleeve can be manufactured by winding around a core while being initially attached to the protrusion. Preferably, the sleeve is reduced to its simplest expression of cylindrical tube or of frustoconical shape and the external protuberance is transferred to the input or output terminal to be connected to the sleeve. Preferably, this terminal is directly linked to the sleeve.
Avantageusement, la ou les zones expansibles sont constituées dans une portion du manchon d'allure tronconique, ce qui permet d'assurer un contact électrique entre la tige transversale et les zones expansibles aux extrémités de ces dernières.Advantageously, the expandable zone or zones are formed in a portion of the frustoconical-looking sleeve, which makes it possible to ensure electrical contact between the transverse rod and the expandable zones at the ends of the latter.
Avantageusement, les deux extrémités axiales du manchon sont chanfreinées, cette configuration permet de facilité l'insertion ou l'extraction de la tige transversale par rapport au connecteur.Advantageously, the two axial ends of the sleeve are chamfered, this configuration makes it easier to insert or extract the transverse rod relative to the connector.
Avantageusement, les manchons sont chacun disposés dans un fût en matériau isolant de type plastique, le fût faisant partie d'un des boîtiers isolant, les zones expansibles étant en pression sur la paroi interne du fût lorsque la tige transversale y est insérée, ainsi la pression de contact entre la tige et les extrémités des manchons est renforcée afin d'obtenir un meilleur contact électrique entre ces deux éléments.Advantageously, the sleeves are each arranged in a barrel of insulating material of the plastic type, the barrel being part of one of the insulating housings, the expandable zones being under pressure on the internal wall of the barrel when the transverse rod is inserted therein, thus the contact pressure between the rod and the ends of the sleeves is reinforced in order to obtain better electrical contact between these two elements.
Avantageusement, la tige transversale comporte, à une extrémité, une tête munie de moyens d'entrainement en rotation de la tige, du type tête de vis par exemple, ladite tête venant en appui contre une paroi latérale d'un boîtier isolant de la rangée, de préférence un des deux boîtiers d'extrémité. Cette tête possède deux fonctions, c'est-à-dire de permettre un appui sur une paroi latérale d'un boîtier de l'ensemble et de permettre l'entrainement en rotation de la tige par des moyens d'entrainement de la tige en rotation tel qu'une fente ou une nervure perpendiculaire à l'axe de la tige par exemple ou par une empreinte de vissage ou tout autre moyen permettant cet entrainement en rotation de la tige.Advantageously, the transverse rod comprises, at one end, a head provided with means for driving the rod in rotation, of the screw head type for example, said head coming to bear against a wall side of an insulating box in the row, preferably one of the two end boxes. This head has two functions, that is to say to allow support on a side wall of a housing of the assembly and to allow the rod to be rotated by means of the rod driving means. rotation such as a slot or a rib perpendicular to the axis of the rod for example or by a screwing impression or any other means allowing this rotational training of the rod.
Avantageusement, la tige transversale comporte une partie d'extrémité filetée, opposée à l'emplacement de la tête, destinée à se visser dans un filetage situé dans une paroi latérale de l'un parmi les boîtiers isolants. Préférentiellement, lorsque la tige transversale est en position d'assemblage d'au moins deux appareils électriques contenus dans deux boîtiers isolants dans une rangée, la tête de la tige transversale est en appui sur une paroi d'un premier boîtier d'extrémité et la partie filetée de la tige est vissée dans un filetage situé dans une paroi latérale de l'autre boîtier d'extrémité. Préférentiellement, le filetage est borgne afin d' éviter tout accès par l'extérieur de l'ensemble à une pièce sous tension. Ainsi la tige transversale peut être fixée mécaniquement par vissage à l'un des boîtiers d'extrémité et maintenir un effort presseur dirigé le long de la dite tige sur l'autre boîtier d'extrémité. Ainsi, selon la direction de cet effort et de par le fait que la tige est transversale aux boîtiers, tous les boîtiers constituants l'ensemble sont maintenus de telle sorte que leurs grandes faces sont accolées.Advantageously, the transverse rod has a threaded end portion, opposite the location of the head, intended to be screwed into a thread located in a side wall of one of the insulating housings. Preferably, when the transverse rod is in the assembly position of at least two electrical devices contained in two insulating housings in a row, the head of the transverse rod is supported on a wall of a first end housing and the threaded part of the rod is screwed into a thread located in a side wall of the other end housing. Preferably, the thread is blind in order to avoid any access from the outside of the assembly to a live part. Thus, the transverse rod can be mechanically fixed by screwing to one of the end boxes and maintain a pressing force directed along said rod on the other end box. Thus, according to the direction of this effort and by the fact that the rod is transverse to the housings, all the housings constituting the assembly are held so that their large faces are joined.
Préférentiellement, la tige transversale comporte une partie d'extrémité filetée à l'intérieur de la tige, opposée à la tête de la tige, ledit ensemble comprenant en outre une vis reçue dans la partie d'extrémité filetée, la vis s'appuyant sur une paroi latérale de l'un parmi les boîtiers isolants.Preferably, the transverse rod has a threaded end part inside the rod, opposite the head of the rod, said assembly further comprising a screw received in the threaded end part, the screw resting on a side wall of one of the insulating boxes.
Dans cette variante, l'assemblage de l'ensemble est équivalent à celui décrit ci-dessus. La tête de la tige transversale est en appui sur une paroi d'un premier boîtier d'extrémité et la vis qui s'insère dans la partie filetée de la tige est en appui sur une paroi latérale de l'autre boîtier d'extrémité de l'ensemble. Ainsi, la tige transversale peut être fixée mécaniquement par vissage à l'un des boîtiers d'extrémité afin de maintenir un effort presseur dirigé le long de la dite tige sur l'autre boîtier d'extrémité via la tête de la tige. Ainsi, selon la direction de cet effort et de par le fait que la tige est transversale aux boîtiers de l'ensemble, tous les boîtiers constituants l'ensemble sont maintenus de telle sorte que leurs grandes faces sont accolées.In this variant, the assembly of the assembly is equivalent to that described above. The head of the transverse rod is supported on a wall of a first end housing and the screw which is inserted in the threaded part of the rod is supported on a side wall of the other end housing all. Thus, the transverse rod can be mechanically fixed by screwing to one of the end boxes in order to maintain a pressing force directed along said rod on the other end box via the head of the rod. Thus, according to the direction of this effort and by the fact that the rod is transverse to the housings of the assembly, all the housings constituents the whole are maintained so that their large faces are joined.
Ces deux configurations permettent un serrage des boîtiers compris entre la tête de la tige transversale et sa partie fileté, ce serrage étant exercé longitudinalement par rapport à la tige et permettant le maintien des appareils électriques de telle sorte que leurs grandes faces sont accolées.These two configurations allow tightening of the housings comprised between the head of the transverse rod and its threaded part, this tightening being exerted longitudinally with respect to the rod and allowing the maintenance of electrical apparatuses so that their large faces are joined.
Préférentiellement, l'un des appareils électriques est un module différentiel comportant au moins une borne de connexion électrique de sortie, l'un au moins parmi les autres appareils électriques étant un disjoncteur comportant au moins une borne de connexion électrique d'entrée, le système de liaison mécanique et électrique reliant une borne de connexion électrique de sortie à au moins une borne de connexion électrique d'entrée.Preferably, one of the electrical devices is a differential module comprising at least one electrical output connection terminal, at least one of the other electrical devices being a circuit breaker comprising at least one electrical input connection terminal, the system mechanical and electrical connection connecting an electrical output connection terminal to at least one electrical input connection terminal.
Cette configuration permet avantageusement de réaliser un appareillage monobloc du type disjoncteur différentiel ou interrupteur différentiel sur la base de deux types de modules existant, l'assemblage et le maintien mécanique de ces modules entre eux étant réalisé par le système de liaison mécanique et électrique, ce système assurant la distribution d'un potentiel de la sortie du module de type différentiel à l'entrée d'au moins un module de type disjoncteur. Cette configuration permet avantageusement de disposer le système de liaison mécanique et électrique à l'intérieur du volume occupé par les différents modules constituant l'ensemble libérant ainsi l'espace extérieur aux modules pour le passage d'autres éléments de l'installation électrique dans laquelle l'ensemble est installé, tel de des câbles par exemple. Cette configuration permet également une industrialisation aisée de l'assemblage de ces ensembles puisque l'assemblage mécanique et la distribution du potentiel (liaison électrique) sont assurés par le seul système de liaison mécanique et électrique, et comme ce système est intégré au volume des boîtiers, l'encombrement de l'ensemble est optimisé, donc la manipulation des ensembles assemblés est facilitée.This configuration advantageously makes it possible to produce a one-piece switchgear of the differential circuit breaker or differential switch type on the basis of two types of existing modules, the assembly and mechanical maintenance of these modules between them being carried out by the mechanical and electrical connection system, this system ensuring the distribution of a potential from the output of the differential type module to the input of at least one circuit breaker type module. This configuration advantageously makes it possible to have the mechanical and electrical connection system inside the volume occupied by the various modules constituting the assembly thus freeing up the space outside the modules for the passage of other elements of the electrical installation in which the assembly is installed, such as cables for example. This configuration also allows easy industrialization of the assembly of these assemblies since the mechanical assembly and the distribution of the potential (electrical connection) are ensured by the only mechanical and electrical connection system, and as this system is integrated into the volume of the housings , the overall dimensions of the assembly are optimized, so the handling of the assembled assemblies is facilitated.
Préférentiellement, l'ensemble est caractérisé en ce qu'il comprend quatre appareils électriques par exemple de type disjoncteur, interrupteur, bloc différentiel et en ce que l'un des appareils électriques est un module différentiel comportant au moins une borne de connexion électrique de sortie, les trois autres appareils électriques étant des disjoncteurs comportant chacun au moins une borne de connexion électrique d'entrée, le système de liaison mécanique et électrique reliant au moins une borne de connexion électrique de sortie à moins une borne de connexion électrique d'entrée de chacun des disjoncteurs afin de distribuer un potentiel électrique entre celles-ci. Avantageusement cette configuration correspond à un cas de montage très répandu, de ce fait l'électricien monteur n'a plus à câbler individuellement les différents appareils entre eux, il se contente d'installer directement l'ensemble dans l'installation électrique et gagne ainsi un temps précieux. Préférentiellement, l'ensemble comporte un module différentiel et trois modules disjoncteurs.Preferably, the assembly is characterized in that it comprises four electrical devices, for example of the circuit breaker, switch, differential block type, and in that one of the electrical devices is a differential module comprising at least one electrical output connection terminal. , the other three electrical appliances being circuit breakers each comprising at least one electrical input connection terminal, the mechanical and electrical connection system connecting at least one electrical output connection terminal to at least one electrical input connection terminal of each of the circuit breakers in order to distribute a potential electric between them. Advantageously, this configuration corresponds to a very widespread mounting case, therefore the assembling electrician no longer has to individually wire the various devices to each other, he is content to install the assembly directly in the electrical installation and thus gains precious time. Preferably, the assembly includes a differential module and three circuit breaker modules.
Préférentiellement, les disjoncteurs sont du type phase-neutre.Preferably, the circuit breakers are of the phase-neutral type.
Préférentiellement, seul le neutre est distribué par le système de liaison mécanique et électrique. Préférentiellement, l'ensemble ainsi constitué est caractérisé en ce que les bornes électriques d'entrée du module différentiel s'étendent sur toute une face de l'ensemble, ainsi l'opérateur électricien dispose de toute cette surface afin de pouvoir connecter les différentes entrées dudit appareil différentiel au réseau électrique. De plus, les bornes d'entrée étant réparties sur toute cette surface, la taille maximum de chaque conducteur à connecter est ainsi optimisée.Preferably, only the neutral is distributed by the mechanical and electrical connection system. Preferably, the assembly thus formed is characterized in that the electrical input terminals of the differential module extend over an entire face of the assembly, so the electrician operator has all this surface in order to be able to connect the various inputs of said differential device to the electrical network. In addition, the input terminals being distributed over this entire surface, the maximum size of each conductor to be connected is thus optimized.
Préférentiellement, les deux grandes faces parallèles d'au moins deux boîtiers consécutifs de la rangée, consistent en une pièce mitoyenne aux deux dits boîtiers consécutifs de la rangée. Ainsi le gain de matière réalisé par l'intégration de ces deux faces dans le même élément mitoyen permet une optimisation économique de l'ensemble.Preferably, the two large parallel faces of at least two consecutive boxes of the row, consist of a part adjoining the two said consecutive boxes of the row. Thus the material gain achieved by the integration of these two faces in the same adjoining element allows economic optimization of the whole.

La vis 102 étant en contact avec la tige 100 qui distribue un potentiel électrique, elle est de ce fait elle-même au même potentiel électrique que celui de la tige 100. Comme le trou 105 est débouchant sur une paroi extérieure d'un boîtier de l'ensemble, la tête de la vis 102 est donc accessible pour un utilisateur et présente un risque de choc électrique lorsque les appareils de l'ensemble sont en service. Une solution possible est de décaler le lamage du fond du trou 105 afin que la tête de la vis ne soit plus accessible par le doigt de l'utilisateur. Dans ce cas la tête de la vis 102 reste toujours visible pour l'utilisateur et il est protéger. Une autre option est celle qui est représentée aux
