Description

L'invention concerne un boítier pour appareillage électrique comportant :

  • un premier flasque comprenant une première paroi latérale et des premières parois de contour disposées sensiblement perpendiculairement au bord de la première paroi latérale,
  • un second flasque comprenant une seconde paroi latérale et des secondes parois de contour disposées sensiblement perpendiculairement au bord de la seconde paroi latérale,
  • des moyens de maintien des premier et second flasques face à face, les premières et les secondes parois de contour étant en contact, et
  • au moins un bloc de jonction électrique disposé sur une partie externe du boítier.
The invention relates to a box for electrical equipment comprising:
  • a first flange comprising a first side wall and first contour walls arranged substantially perpendicular to the edge of the first side wall,
  • a second flange comprising a second side wall and second contour walls arranged substantially perpendicular to the edge of the second side wall,
  • means for holding the first and second flanges face to face, the first and second contour walls being in contact, and
  • at least one electrical terminal block disposed on an external part of the housing.

Un tel boítier pour appareillage électrique est connu du document DE 29606759 U1 dans lequel les flasques du boítier sont maintenus l'un à l'autre seulement par des moyens d'accrochage intégrés dans les parois de contour desdits flasques.Such a box for electrical apparatus is known from document DE 29606759 U1 in which the flanges of the housing are held together only by means attachment integrated in the contour walls of said flanges.

Des boítiers pour appareillage électrique modulaire comportent de manière connue deux flasques ou deux demi-coquilles à assembler. Généralement, les deux flasques sont disposés l'un contre l'autre puis assemblés par des vis ou des rivets. Chaque flasque comprend généralement des colonnes de forme cylindrique et ouvertes sur les parois dudit flasque de manière à pouvoir introduire les rivets ou les vis.Boxes for modular electrical equipment comprise in known manner two flanges or two half-shells to assemble. Generally, the two flanges are arranged one against the other and then assembled by screws or rivets. Each flange includes generally columns of cylindrical shape and open on the walls of said flange of so you can insert the rivets or screws.

Lors de l'assemblage, des colonnes complémentaires de chaque flasque sont disposées dans le prolongement de leurs axes respectifs afin d'introduire les rivets. Après avoir été introduits dans chaque colonne, les rivets sont sertis à l'aide d'un outil spécial.During assembly, complementary columns of each flange are arranged in the extension of their respective axes in order to introduce the rivets. After being introduced in each column, the rivets are crimped using a special tool.

L'assemblage par vis est réalisé selon le même principe. Les vis sont introduites dans les colonnes puis vissées dans des écrous. Il est également possible de visser les vis directement dans la masse du boítier. Dans ce cas, les vis traversent librement une première colonne ayant un diamètre intérieur plus grand que le diamètre des vis. Puis, les vis sont vissées dans une seconde colonne complémentaire ayant un diamètre intérieur plus petit que le diamètre des vis.The assembly by screws is carried out according to the same principle. The screws are inserted in the columns then screwed into nuts. It is also possible to screw the screws directly in the mass of the case. In this case, the screws pass freely through a first column having an inside diameter larger than the diameter of the screws. Then the screws are screwed into a second complementary column having an inner diameter smaller than the diameter of the screw.

L'assemblage par rivets ou par vis nécessite des outils spéciaux. Ceci conduit à un temps de montage important et à un coût de fabrication des appareils très élevé. De plus, ces modes de fixation ne permettent pas d'avoir des boítiers indémontables. En effet, il est facile de démonter un boítier fixé par des vis ou d'enlever un rivet et le remplacer par un autre.Assembly using rivets or screws requires special tools. This leads to a time of significant assembly and very high cost of manufacturing the devices. In addition, these modes of fixing do not allow to have non-removable cases. Indeed, it is easy to dismantle a case fixed by screws or remove a rivet and replace it with another.

L'invention a pour but un boítier pour appareillage électrique pouvant être assemblé rapidement sans outils spéciaux ainsi qu'un appareil électrique comportant un tel boítier. The object of the invention is to provide a housing for electrical equipment which can be assembled. quickly without special tools and an electrical device comprising such a housing.

Advantageously, the third attachment means comprise at least three points of attachment to the contour walls, a first attachment point being located towards the bottom of the housing, a second attachment point being located towards an upstream side of the housing, and a third attachment point being located towards a downstream side of the housing.

Pour rendre le boítier indémontable, les troisièmes moyens d'accrochage sont disposés de manière peu accessible par l'extérieur des parois pour empêcher l'ouverture du boítier sans déformation des flasques.To make the housing non-removable, the third attachment means are arranged not easily accessible from the outside of the walls to prevent opening of the housing without deformation of the flanges.

Le boítier comporte un capot constituant la face avant dudit boítier et fixé par des moyens de fixation par accrochage sur des parois des flasques, lesdits moyens de fixation par accrochage n'étant pas manoeuvrables par l'extérieur du boítier, et les parois de contour ayant une ouverture située vers la face avant du boítier.The housing comprises a cover constituting the front face of said housing and fixed by means of fixing by hooking on the walls of the flanges, said means of fixing by hooking not being maneuverable from the outside of the case, and the contour walls having a opening located towards the front face of the case.

De préférence, le bloc de jonction électrique comporte des moyens de séparation diélectrique comportant un rebord de manière à augmenter une distance d'isolement entre deux bornes, des moyens de connexion électrique, les séparations diélectriques étant en contact avec les parois de contour du boítier.Preferably, the electrical terminal block includes dielectric separation means comprising a flange so as to increase an insulation distance between two terminals, electrical connection means, the dielectric separations being in contact with the walls of outline of the case.

Un appareil électrique selon un mode de réalisation de l'invention comporte un boítier selon des modes de réalisation décrits ci-dessus, un circuit électrique disposé à l'intérieur dudit boítier, et des conducteurs électriques connectés audit circuit et traversant les parois de contour pour coopérer avec des bornes des moyens de connexion électriques d'un bloc de jonction.An electrical appliance according to an embodiment of the invention comprises a housing according to of the embodiments described above, an electrical circuit arranged inside said housing, and electrical conductors connected to said circuit and passing through the walls of contour to cooperate with terminals of the electrical connection means of a block of junction.

Un boítier modulaire pour appareillage électrique selon un mode de réalisation comporte un premier flasque 1 et un second flasque 2 représentés respectivement sur les figures 1 et 2. Le premier flasque 1 comporte une première paroi 3 latérale et des premières parois de contour 4. Le second flasque 2 comporte également une seconde paroi 5 latérale et des secondes parois de contour 6. Pour le montage du boítier, les flasques sont disposés face à face et les premières et secondes parois de contour sont positionnées en contact de manière à fermer le contour dudit boítier. Ainsi formé, le boítier comporte un fond 7 destiné à être fixé sur un support, un premier côté amont 8 et un second côté aval 9 perpendiculaires au fond et aux parois latérales. Le support est, de préférence, un rail symétrique.A modular box for electrical equipment according to one embodiment comprises a first flange 1 and a second flange 2 shown respectively in FIGS. 1 and 2. The first flange 1 has a first side wall 3 and first contour walls 4. The second flange 2 also has a second side wall 5 and second walls of contour 6. For the assembly of the case, the flanges are arranged face to face and the first and second contour walls are positioned in contact so as to close the contour of said housing. Thus formed, the housing has a bottom 7 intended to be fixed on a support, a first upstream side 8 and a second downstream side 9 perpendicular to the bottom and to side walls. The support is preferably a symmetrical rail.

Selon un mode de réalisation de l'invention, les flasques 1 et 2 sont maintenues par des blocs de jonction électrique 10 et 11 représentés sur les figures 3 et 4. Chaque bloc de jonction électrique comporte une première partie 12 destinée à être en contact avec un côté amont ou aval des parois de contour, et deux parois de maintien 13 et 14 perpendiculaires à ladite première partie. Chaque paroi de maintien des blocs de jonction électrique est en contact avec une face extérieure de chaque paroi latérale pour maintenir les flasques face à face dans leur positon respective.According to one embodiment of the invention, the flanges 1 and 2 are held by blocks electrical junction 10 and 11 shown in Figures 3 and 4. Each terminal block electric comprises a first part 12 intended to be in contact with an upstream side or downstream of the contour walls, and two retaining walls 13 and 14 perpendicular to said first part. Each retaining wall of the electrical terminal blocks is in contact with an outer face of each side wall to keep the flanges face to face in their respective position.

Les parois de maintien comportent un premier dispositif d'accrochage pour fixer les blocs de jonction électrique sur les parois des flasques. Ce dispositif comporte de préférence des languettes 15 prolongeant les parois de maintien et comportant des ergots 16 d'accrochage destinés à coopérer avec des encoches 17 situées dans les parois latérales du boítier.The retaining walls comprise a first attachment device for fixing the blocks of electrical junction on the walls of the flanges. This device preferably includes tongues 15 extending the retaining walls and comprising lugs 16 for hooking intended to cooperate with notches 17 located in the side walls of the housing.

Pour assurer une fixation plus efficace du bloc de jonction, les parois latérales des flasques comportent des avancées 18 comprenant un second dispositif d'accrochage pour fixer lesdites parois latérales à la première partie 12 des blocs de jonction électrique. Ce second dispositif d'accrochage comporte par exemple des languettes 19 élastiques découpées dans la masse des avancées et des ouvertures 20 situées dans la première partie des blocs de jonction électrique.To ensure more efficient fixing of the terminal block, the side walls of the flanges include projections 18 comprising a second hooking device for fixing the said side walls at the first part 12 of the electrical terminal blocks. This second device for attachment comprises for example elastic tabs 19 cut from the mass of projections and openings 20 located in the first part of the electrical terminal blocks.

Lors de la mise en place des blocs de jonction électrique, pour maintenir les flasques, les avancées 18 sont glissées sur la première partie 12 du bloc et les parois de maintien 14 sont glissées sur les faces extérieures des parois latérales 3 et 5. Puis, en bout de course, lorsque le bloc est en place, les languettes 15 s'accrochent sur les encoches 17 et les languettes 19 entrent dans les ouvertures 20 pour bloquer le bloc de jonction électrique sur les flasques.When installing the electrical terminal blocks, to maintain the flanges, the projections 18 are slid over the first part 12 of the block and the retaining walls 14 are slid onto the outer faces of the side walls 3 and 5. Then, at the end of the travel, when block is in place, the tabs 15 catch on the notches 17 and the tabs 19 enter in the openings 20 to block the electrical terminal block on the flanges.

Lorsque les deux blocs de jonction électrique sont mis en place respectivement sur les côtés amont et aval, les deux flasques sont solidarisés. Il est alors possible de mettre en place un capot 21 sur la partie avant du boítier, à l'opposé du fond. Ce capot 21 est de préférence fixé par un dispositif à accrochage. Ledit dispositif comporte par exemple des ergots d'accrochage sur le bord du capot et des encoches au bord des parois de contour des flasques.When the two electrical terminal blocks are placed on the sides respectively upstream and downstream, the two flanges are secured. It is then possible to set up a cover 21 on the front part of the case, opposite the bottom. This cover 21 is preferably fixed by a hooking device. Said device comprises for example hooking lugs on the edge of the cover and of the notches at the edge of the contour walls of the flanges.

Le montage d'un tel boítier est très facile et ne nécessite aucun outil particulier. En effet, le montage consiste à maintenir les flasques l'un contre l'autre, puis à mettre en place les blocs de jonction côté amont et côté aval jusqu'à l'accrochage des languettes, et à fixer le capot par simple pression. The assembly of such a housing is very easy and does not require any particular tool. Indeed, the mounting consists of holding the flanges against each other, then putting the blocks in place junction upstream side and downstream side until the tabs are hooked, and fix the cover by one touch.

Les flasques peuvent aussi être maintenus dans leurs positions respectives par un troisième dispositif de fixation à accrochage.The flanges can also be held in their respective positions by a third hooking fastening device.

Dans le mode de réalisation particulier des figures 1 et 2, ces dispositifs comportent notamment des languettes 22a à 22d souples disposées sur des faces internes des parois latérales dans le prolongement des parois de contour. Lesdites languettes comportent à leur extrémité des ergots d'accrochage respectivement 23a et 23d. A l'opposé des languettes, les parois de contour comportent des encoches 24a et 24d, ou des épaulements pour recevoir les ergots d'accrochage et verrouiller la fermeture du boítier.In the particular embodiment of Figures 1 and 2, these devices include in particular flexible tabs 22a to 22d arranged on internal faces of the walls lateral in the extension of the contour walls. Said tabs have at their end of the hooking pins 23a and 23d respectively. In contrast to the tabs, the contour walls have notches 24a and 24d, or shoulders to receive the hooking lugs and lock the closure of the housing.

De préférence, le boítier comporte au moins trois points de fixation, un premier point correspondant à une première languette 22a disposée sur le côté aval et coopérant avec une première encoche 24a, un second point de fixation correspondant à une seconde languette 22b disposée sur le côté amont et coopérant avec une seconde encoche 24b, et un troisième point de fixation correspondant à une troisième languette 22c ou 22d disposée sur le fond du boítier et coopérant avec une troisième encoche respectivement 24c ou 24d.Preferably, the housing has at least three fixing points, a first point corresponding to a first tab 22a disposed on the downstream side and cooperating with a first notch 24a, a second fixing point corresponding to a second tab 22b disposed on the upstream side and cooperating with a second notch 24b, and a third attachment point corresponding to a third tab 22c or 22d arranged on the bottom of the housing and cooperating with a third notch respectively 24c or 24d.

Pour garantir le fonctionnement de certains appareils électriques, il est nécessaire de rendre les boítiers indémontables ou difficilement démontables sans détérioration desdits boítiers. Dans des boítiers selon ce mode particulier de réalisation de l'invention, les languettes sont disposées de manière à ne plus être manoeuvrées pour séparer les flasques, toute tentative d'ouverture risquant de déformer le boítier.To guarantee the functioning of certain electrical devices, it is necessary to return the housings which cannot be dismantled or which are difficult to dismantle without damaging said housings. In housings according to this particular embodiment of the invention, the tongues are arranged so that they are no longer maneuvered to separate the flanges, any attempt opening may distort the case.

La figure 6 montre une vue éclatée d'un boítier selon le mode particulier de réalisation de l'invention et la figure 7 montre une vue d'un même boítier assemblé.Figure 6 shows an exploded view of a housing according to the particular embodiment of the invention and Figure 7 shows a view of the same assembled housing.

Dans un appareil électrique selon un mode de réalisation de l'invention, comportant un boítier comme décrit ci-dessus, un circuit électrique 25 est disposé entre les deux flasques 1 et 2.In an electrical appliance according to an embodiment of the invention, comprising a housing as described above, an electrical circuit 25 is disposed between the two flanges 1 and 2.

Selon un mode de réalisation préférentiel, les blocs de jonction électrique comportent des alvéoles destinées à recevoir des bornes 26 de raccordement électrique. Lesdites bornes sont prévues pour être associées à des conducteurs 27 de liaison disposés entre l'intérieur et l'extérieur du boítier. De préférence, les bornes sont des bornes à cage comportant un étrier et une vis de serrage pour maintenir un conducteur de liaison et un conducteur de ligne. Pour le passage des conducteurs de liaison entre l'intérieur et l'extérieur du boítier, les parois de contour comportent des ouvertures 28. According to a preferred embodiment, the electrical terminal blocks include cells intended to receive terminals 26 of electrical connection. Said terminals are designed to be associated with connecting conductors 27 arranged between the interior and the outside of the case. Preferably, the terminals are cage terminals comprising a stirrup and a clamping screw to hold a connecting conductor and a line conductor. For the passage of the connecting conductors between the inside and the outside of the case, the walls of contour have openings 28.

Les blocs de jonction comportent de préférence des cloisons isolantes 29 disposées entre les bornes. Ces cloisons isolantes comportent avantageusement un rebord 30 de largeur supérieure à celle de la cloison de manière à augmenter la distance d'isolement entre les bornes. Lorsque le bloc de jonction est mis en place sur le boítier, le rebord 30 vient en contact avec les parois de contour en amont ou en aval de manière à assurer la continuité de l'isolement électrique et une distance d'isolement élevée à l'extérieur desdites parois de contour du boítier.The terminal blocks preferably include insulating partitions 29 arranged between the terminals. These insulating partitions advantageously include a rim 30 of width greater than that of the partition so as to increase the insulation distance between the terminals. When the terminal block is placed on the housing, the flange 30 comes contact with the upstream or downstream contour walls so as to ensure the continuity of electrical insulation and a high insulation distance outside said walls of outline of the case.

Les conducteurs de liaison 27 peuvent être connectés à l'intérieur du boítier, à des circuits imprimés 25 comportant des circuits électriques et éventuellement des composants électroniques. Le plan des circuits imprimés étant généralement parallèle aux parois latérales, lesdits conducteurs de liaison doivent avoir des formes particulières pour pouvoir relier les bornes de sortie et lesdits circuits.The connecting conductors 27 can be connected inside the housing, to circuits printed matter 25 comprising electrical circuits and possibly components electronic. The plane of the printed circuits being generally parallel to the side walls, said connecting conductors must have particular shapes in order to be able to connect the output terminals and said circuits.

Dans des modes de réalisation préférentiels, les conducteurs électriques sont réalisés en cuivre plat préformé et connectés au circuit imprimé par soudure ou sertissage d'une première extrémité. Lesdits conducteurs représentés sur les figures 8 et 9 ont de préférence une première partie 31 disposée perpendiculairement au plan du circuit imprimé, une seconde partie 32 pliée par rapport à la première partie et une troisième partie 33 sortant des parois de contour.In preferred embodiments, the electrical conductors are made of copper preformed plate and connected to the printed circuit by soldering or crimping a first end. Said conductors shown in Figures 8 and 9 preferably have a first part 31 arranged perpendicular to the plane of the printed circuit, a second part 32 folded with respect to the first part and a third part 33 coming out of the walls of contour.

La première partie comporte des découpes 34 de manière à pouvoir être soudée sur un circuit imprimé par un ou plusieurs points de soudure 35. De préférence, ladite première partie comporte deux extrémités opposées de manière à rendre les conducteurs de liaison réversibles, la seconde partie étant plus proche d'une première extrémité que d'une seconde extrémité. Ce type de conducteurs de liaison préférentiel permet de connecter deux conducteurs de liaison dans le même plan de sortie et d'utiliser deux bornes côte à côte, lesdits conducteurs étant disposés tête bêche comme sur les figures 8 et 9. Chaque extrémité de la première partie comporte des découpes 34 pour pouvoir être soudée sur le circuit imprimé.The first part has cutouts 34 so that it can be soldered on a circuit printed by one or more solder points 35. Preferably, said first part has two opposite ends so as to make the connection conductors reversible, the second part being closer to a first end than to a second end. This preferred type of connection conductor allows two connection conductors to be connected in the same output plane and to use two terminals side by side, said conductors being arranged head to tail as in Figures 8 and 9. Each end of the first part has cutouts 34 so that it can be soldered onto the printed circuit.
