La quasi-totalité des boîtes à bornes d'alternateurs industriels sont construites par un assemblage de multiples éléments métalliques.  Virtually all industrial alternator terminal boxes are constructed by an assembly of multiple metal elements.
La confection et l'assemblage de ces éléments métalliques sont fastidieux et nécessitent la mise en œuvre d'une grande quantité d'éléments de visserie ainsi que l'ajout de supports pour assurer le maintien à l'intérieur de la boîte à bornes de différents modules électroniques spécifiques à chaque machine électrique.  The making and assembly of these metal elements are tedious and require the implementation of a large amount of hardware and the addition of supports to ensure the maintenance inside the terminal box of different electronic modules specific to each electric machine.
L'interface mécanique de la boîte à bornes avec le carter de la machine nécessite souvent la réalisation de formes assez complexe. Dans ces zones d'interfaces, les dispersions dimensionnelles dans l'assemblage introduisent souvent des précontraintes importantes, et sous l'effet de sollicitations vibratoires, des éléments de tôlerie peuvent se déchirer par fatigue.  The mechanical interface of the terminal box with the housing of the machine often requires the realization of fairly complex shapes. In these interface areas, the dimensional dispersions in the assembly often introduce significant prestressing, and under the effect of vibratory stresses, sheet metal elements can tear by fatigue.
Lorsque la machine électrique est un alternateur qui est associé à un moteur thermique d'entraînement, pour former un groupe électrogène, une armoire de contrôle est généralement prévue. Cette armoire est disposée de façon différente selon les constructeurs, et peut se situer par exemple au-dessus de l'alternateur, sur le ou les côtés, ou sur l'arrière. Quelle que soit la position retenue, l'accès à l'intérieur de la boîte à bornes doit être possible avec un maximum de facilité pour effectuer par exemple les réglages d'un régulateur de tension présent à l'intérieur.  When the electric machine is an alternator that is associated with a drive engine, to form a generator, a control cabinet is generally provided. This cabinet is arranged differently according to the manufacturers, and can be located for example above the alternator, on the side or sides, or on the back. Whatever the position chosen, access to the inside of the terminal box must be possible with maximum ease to perform for example the settings of a voltage regulator present inside.
Il existe un besoin pour simplifier la fabrication des boîtes à bornes des machines électriques, notamment en diminuant le nombre de pièces constitutives pour tendre vers une standardisation, tout en gardant constante voire en améliorant la tenue à la dégradation par fatigue de la boîte et la facilité d'accès à son intérieur. L'invention a ainsi pour objet, selon un premier de ses aspects, une machine électrique tournante, comportant un carter de machine et une boîte à bornes rapportée sur le carter, la boîte à bornes comportant une embase, celle-ci définissant au moins : There is a need to simplify the manufacture of terminal boxes for electrical machines, in particular by reducing the number of components to tend towards standardization, while keeping constant or improving the resistance to fatigue degradation of the box and ease access to its interior. The invention thus has, according to a first of its aspects, a rotating electrical machine, comprising a machine housing and a terminal box attached to the housing, the terminal box having a base, the latter defining at least:
- une zone de fixation d'au moins un module électronique, cette zone de fixation comportant un ou plusieurs éléments de support pour recevoir des éléments de fixation du ou des modules,  a zone for fixing at least one electronic module, this fixing zone comprising one or more support elements for receiving fastening elements of the module or modules,
- une zone de raccordement électrique, cette dernière comportant au moins un plot de réception d'au moins un élément de connexion électrique,  an electrical connection zone, the latter comprising at least one receiving pad of at least one electrical connection element,
le ou les éléments de support et le ou les plots étant moulés d'une seule pièce avec l'embase. the support element or elements and the or pads being molded in one piece with the base.
Grâce à l'invention, la fabrication de la boîte à bornes et l'assemblage de ses éléments constitutifs et de son contenu sont facilités. L'embase peut assurer l'ensemble des interfaces entre le carter de la machine et l'ensemble des modules électroniques et permettre le montage d'un capot.  Thanks to the invention, the manufacture of the terminal box and the assembly of its constituent elements and its contents are facilitated. The base can ensure all interfaces between the machine housing and all electronic modules and allow the mounting of a cover.
La zone de fixation du ou des modules électroniques comporte un ou plusieurs éléments de support pour recevoir des éléments de fixation du ou des modules, le ou les éléments de fixation étant de préférence des écrous à pinces. Le ou les modules électroniques peuvent ainsi être maintenus fermement au sein de la zone de fixation grâce aux éléments de fixation reçus par le ou les éléments de support. Le montage du ou des modules et de leurs diverses options peut se faire facilement, sans ajout de platines ou de supports de fixation rapportés.  The zone of attachment of the electronic module or modules comprises one or more support elements for receiving fastening elements of the module or modules, the fastening element or elements being preferably pliers nuts. The electronic module (s) can thus be held firmly within the fixing zone by virtue of the fastening elements received by the support element (s). The mounting of the module or modules and their various options can be done easily, without adding plates or reported mounting brackets.
Les éléments de support permettent d'offrir une quantité quasi-illimitée de configurations d'aménagement, en fonction des besoins de la machine électrique.  The support members provide an almost unlimited amount of layout configurations, depending on the needs of the electrical machine.
Le nombre d'éléments de support est de préférence supérieur ou égal à deux, de façon à permettre à au moins un module d'être fixé sur deux éléments de support.  The number of support elements is preferably greater than or equal to two, so as to allow at least one module to be fixed on two support elements.
Lorsque la machine électrique comporte plusieurs modules électroniques, les éléments de support sur lesquels repose un module électronique sont différents de ceux sur lesquels reposent le ou les autres modules.  When the electrical machine comprises several electronic modules, the support elements on which rests an electronic module are different from those on which rest or the other modules.
Le ou les éléments de support sont de préférence prépercés ; le ou les éléments de support comportent avantageusement au moins un perçage en excès, une fois le ou les modules électroniques en place ; et les perçages sont répartis de préférence sur sensiblement toute leur longueur. Les éléments de fixation peuvent comporter des écrous à pinces, et le ou les éléments de support peuvent comporter des logements facilitant leur positionnement, tels que des renfoncements de contour sensiblement rectangulaire.

The fastening elements may comprise pliers nuts, and the support element or elements may comprise housings facilitating their positioning, such as recesses of substantially rectangular contour.
Le ou les modules électroniques peuvent être choisis parmi les régulateurs de tension et les variateurs de vitesse, et le ou l'un au moins des modules électroniques peu(ven)t être relié(s) à des conducteurs électriques de la machine électrique tournante, de préférence par l'intermédiaire du ou des éléments de connexion électrique.  The electronic module or modules may be chosen from voltage regulators and variable speed drives, and the at least one of the electronic modules may be connected to electrical conductors of the rotary electrical machine. preferably via the electrical connection element or elements.
La zone de raccordement peut comporter une pluralité de plots agencés à intervalles réguliers dans au moins une direction, mieux dans deux directions perpendiculaires entre elles.  The connection zone may comprise a plurality of studs arranged at regular intervals in at least one direction, better in two directions perpendicular to each other.
Le ou les éléments de connexion électrique peuvent comporter des inserts métalliques filetés, ce qui permet d'adapter la configuration de raccordements électriques à différents couplages électriques (4 fils, 6 fils, 12 fils ...). Chaque insert métallique fileté peut recevoir un goujon fileté sur lequel sont disposées une ou plusieurs cosses reliées à des conducteurs électriques, ces cosses étant maintenues sur le goujon à l'aide d'écrou(s). Les inserts métalliques filetés sont ainsi, avantageusement, des inserts femelles filetés intérieurement.  The electrical connection element or elements may comprise threaded metal inserts, which makes it possible to adapt the configuration of electrical connections to different electrical couplings (4-wire, 6-wire, 12-wire, etc.). Each threaded metal insert can receive a threaded stud on which are disposed one or more lugs connected to electrical conductors, these lugs being held on the stud with nut (s). The threaded metal inserts are thus advantageously female inserts threaded internally.
L'embase peut être surmoulée sur les inserts femelles.  The base can be overmolded on the female inserts.
La zone de raccordement peut être centrale et l'embase définit de préférence au moins deux zones de fixation disposées de part et d'autre de la zone de raccordement centrale, notamment sur les côtés latéraux de l'embase.  The connection zone may be central and the base preferably defines at least two attachment zones disposed on either side of the central connection zone, in particular on the lateral sides of the base.
L'embase est de préférence symétrique par rapport à un plan médian longitudinal.  The base is preferably symmetrical with respect to a longitudinal median plane.
La machine peut comporter un capot fixé sur l'embase, ce capot comportant de préférence au moins un panneau individuel amovible pouvant être séparé de la boîte à bornes sans enlèvement du capot dans sa totalité.  The machine may comprise a cover fixed to the base, this cover preferably comprising at least one removable individual panel that can be separated from the terminal box without removing the cover in its entirety.
Le capot peut comporter des panneaux avant et arrière, des panneaux latéraux et un couvercle, tous ces éléments pouvant être amovibles les uns par rapport aux autres afin de faciliter l'accès dans différentes configurations de groupe électrogène par exemple.  The hood may include front and rear panels, side panels and a lid, all of which can be removable relative to each other to facilitate access in different generator configurations, for example.
L'embase peut comporter des logements de réception d'éléments de fixation du capot sur l'embase.  The base may comprise housing for receiving fastening elements of the cover on the base.
Le capot peut être métallique. En particulier, les panneaux et/ou le couvercle peuvent être réalisés à partir de feuilles d'acier rectangulaires en minimisant le temps de fabrication et les chutes de matière. The hood can be metallic. In particular, the panels and / or the cover can be made from rectangular steel sheets while minimizing the manufacturing time and material falls.
Le carter est de préférence de forme cylindrique, l'axe du cylindre étant de préférence horizontal. L'embase est de préférence rapportée sur la surface latérale du cylindre, notamment sur sa partie supérieure.  The casing is preferably of cylindrical shape, the axis of the cylinder being preferably horizontal. The base is preferably attached to the lateral surface of the cylinder, in particular on its upper part.
Selon une autre caractéristique avantageuse de l'invention, l'embase est moulée dans une matière thermoplastique, éventuellement renforcée par une charge minérale. Ceci permet de reporter toute complexité de formes de la boîte à bornes sur une pièce plastique moulée et donc facile à réaliser.  According to another advantageous characteristic of the invention, the base is molded in a thermoplastic material, possibly reinforced by a mineral filler. This makes it possible to postpone any complexity of shapes of the terminal box on a molded plastic part and thus easy to produce.
De plus, de par la plasticité de son matériau, l'embase s'affranchit très facilement des variations dimensionnelles du carter de la machine et réduit donc considérablement les risques de dégradation par fatigue.  In addition, due to the plasticity of its material, the base is very easily freed from dimensional changes in the casing of the machine and thus considerably reduces the risk of degradation by fatigue.
La boîte à bornes peut être dépourvue de fiche de raccordement électrique extérieure. L'accès à la zone de raccordement électrique nécessite l'ouverture de la boîte à bornes.  The terminal box may have no external electrical connection plug. Access to the electrical connection area requires the opening of the terminal box.
Le raccordement électrique peut s'effectuer grâce à des conducteurs électriques qui viennent de l'extérieur de la machine et se raccordent à l'intérieur de la boîte à bornes dans la zone de raccordement électrique. Une traversée de câble étanche à presse étoupe peut être prévue à travers une paroi de la boîte à bornes.  The electrical connection can be made by means of electrical conductors coming from outside the machine and connected inside the terminal box in the electrical connection area. A sealed cable feedthrough with cable gland can be provided through a wall of the terminal box.
L'invention pourra être mieux comprise à la lecture de la description détaillée qui va suivre, d'exemples de mise en œuvre non limitatifs de celle-ci, et à l'examen du dessin annexé, sur lequel :  The invention will be better understood on reading the detailed description which follows, examples of non-limiting implementation thereof, and on examining the appended drawing, in which:
- la figure 1 représente en perspective, de façon schématique et partielle, une boîte à bornes selon l'invention, disposée sur le carter d'une machine électrique tournante,  FIG. 1 represents in perspective, schematically and partially, a terminal box according to the invention, arranged on the housing of a rotating electrical machine,

la figure 5 représente isolément un élément de fixation, et la figure 6 représente l'élément de fixation de la figure 5 en place sur un élément de support de l'embase. FIG. 5 represents, in isolation, a fixing element, and Figure 6 shows the fastener of Figure 5 in place on a support member of the base.
La machine électrique 1 représentée aux figures 1 et 2 comporte un carter 2 sur lequel est monté une boîte à bornes 3, par exemple en partie supérieure de la machine comme illustré, cette disposition n'étant toutefois qu'un exemple possible parmi d'autres.  The electric machine 1 shown in Figures 1 and 2 comprises a housing 2 on which is mounted a terminal box 3, for example in the upper part of the machine as shown, this provision being however only one possible example among others .
Le carter 2 loge de façon connue en soi un stator de machine électrique et un rotor qui tourne à l'intérieur du stator autour d'un axe de rotation X qui coïncide ici avec l'axe longitudinal de la machine 1.  The casing 2 houses in a manner known per se an electric machine stator and a rotor which rotates inside the stator about an axis of rotation X which coincides here with the longitudinal axis of the machine 1.
Le carter 2 peut comporter, comme illustré, un corps 5 sur lequel est rapporté un flasque 6, celui-ci pouvant, comme illustré, comporter des ouïes d'aération 7.  The casing 2 may comprise, as illustrated, a body 5 on which is attached a flange 6, the latter may, as illustrated, include vents 7.
Dans l'exemple illustré, la boîte à bornes 3 recouvre le corps 5 du carter 2 ainsi qu'une partie du flasque 6.  In the example illustrated, the terminal box 3 covers the body 5 of the housing 2 and a part of the flange 6.
La machine 1 est par exemple un alternateur mais l'invention n'est pas limitée aux alternateurs et peut s'appliquer également à d'autres machines électriques tournantes telles que des moteurs. L'invention s'intéresse de préférence à des machines électriques dont la puissance est supérieure ou égale à 50 kW.  The machine 1 is for example an alternator but the invention is not limited to the alternators and can also be applied to other rotating electrical machines such as motors. The invention is preferably interested in electrical machines whose power is greater than or equal to 50 kW.
La boîte à bornes 3 peut loger un ou plusieurs modules électroniques 20 qui sont par exemple constitués par un ou plusieurs régulateurs ou variateurs.  The terminal box 3 can house one or more electronic modules 20 which consist for example of one or more regulators or dimmers.
Chacun des modules 20 peut comporter un certain nombre d'entrées ou de sorties qui peuvent être reliées électriquement par des câbles non représentés les unes aux autres ainsi qu'aux conducteurs internes de la machine, ces derniers étant fixés à des éléments de connexion électrique 22 situés dans une zone de raccordement électrique 23.  Each of the modules 20 may comprise a number of inputs or outputs that can be electrically connected by cables not shown to each other and to the internal conductors of the machine, the latter being attached to electrical connection elements 22 located in an electrical connection zone 23.
Le ou les modules électroniques 20 sont situés dans des zones de fixation 24 et 25, les zones de fixation 24 et 25 étant disposées par exemple respectivement de part et d'autre de la zone de raccordement 23, notamment à gauche et à droite de celle-ci quand la machine est observée selon son axe longitudinal X.  The electronic module or modules 20 are located in attachment zones 24 and 25, the fixing zones 24 and 25 being arranged for example respectively on either side of the connection zone 23, in particular on the left and on the right of that when the machine is observed along its longitudinal axis X.
Dans l'exemple illustré, les éléments de connexion électriques 22 comportent des inserts métalliques filetés qui sont reçus dans des plots 30 disposés par exemple, comme on peut le voir sur la figure 4, avec un écartement régulier dans la direction longitudinale et dans la direction transversale.  In the example illustrated, the electrical connection elements 22 comprise threaded metal inserts which are received in studs 30 arranged for example, as can be seen in FIG. 4, with a regular spacing in the longitudinal direction and in the direction cross.
Les inserts métalliques filetés sont de préférence incorporés par surmoulage dans l'embase 10. Ils sont de préférence de type femelle. Il est ainsi possible de venir y visser des goujons, non représentés ici, comme par exemple des vis sans tête Hc, en nombre et de longueur adaptés au besoin. The threaded metal inserts are preferably incorporated by overmolding in the base 10. They are preferably of the female type. It is thus possible to come there screw studs, not shown here, such as screws Hc head, in number and length adapted as needed.
Dans l'exemple illustré, les plots 30 sont disposés de manière régulière dans les directions longitudinale et transversale et forment un réseau, avec par exemple quatre rangées de trois plots 30 consécutifs.  In the illustrated example, the pads 30 are arranged regularly in the longitudinal and transverse directions and form a network, for example with four rows of three consecutive pads 30.
Les plots 30 peuvent être reliés entre eux par des nervures 32 qui s'étendent par exemple comme un quadrillage.  The pads 30 may be interconnected by ribs 32 which extend for example as a grid.
La zone de raccordement électrique 23 peut comporter, de part et d'autre des plots 30, dans le sens longitudinal, des pattes 36 de fixation sur le carter, pourvues d'au moins un perçage 37 de passage d'un élément de fixation tel qu'une vis ou un rivet.  The electrical connection zone 23 may comprise, on either side of the pads 30, in the longitudinal direction, lugs 36 for fixing on the housing, provided with at least one piercing hole 37 for passing a fastener element such as than a screw or a rivet.
L'embase 10 comporte dans les zones de fixation 24 et 25 des éléments de support 42, ces éléments de support 42 se présentant par exemple sous la forme de rails prépercés, disposés parallèlement les uns aux autres selon l'axe longitudinal X. Ces rails sont de préférence au nombre de 2 à 10, et sont, comme illustré, avantageusement reliés par des nervures transversales 44, moulées d'une seule pièce avec le reste de l'embase 10, ces nervures transversales 44 améliorant la tenue mécanique de l'embase 10 tout en participant au support des rails.  The base 10 comprises in the attachment zones 24 and 25 support elements 42, these support elements 42 being for example in the form of pre-drilled rails, arranged parallel to each other along the longitudinal axis X. These rails are preferably in the number of 2 to 10, and are, as illustrated, advantageously connected by transverse ribs 44, molded in one piece with the rest of the base 10, these transverse ribs 44 improving the mechanical strength of the base 10 while participating in the support of the rails.
L'embase peut également comporter une ou plusieurs nervures longitudinales The base may also include one or more longitudinal ribs
46. 46.
Les préperçages sont par exemple moulés avec des renfoncements de forme rectangulaire, de façon à accueillir, comme illustré sur la figure 6, des éléments de fixation tels que des écrous à pince 50, dont l'un d'entre eux est représenté isolément à la figure 5.  The pre-drills are for example molded with recesses of rectangular shape, so as to receive, as illustrated in FIG. 6, fastening elements such as clamp nuts 50, one of which is shown in isolation at the figure 5.
Les préperçages sont préférentiellement au nombre de 10 à 100.  Pre-drills are preferentially 10 to 100 in number.
Les écrous à pince 50 peuvent comporter, de façon conventionnelle, un fût 55 fileté intérieurement, supporté par une pince 52, laquelle peut venir s'engager sur un élément de support 42 dans son épaisseur, le fût 55 venant se positionner en regard d'un préperçage.  The collet nuts 50 may comprise, in a conventional manner, an internally threaded barrel 55, supported by a clamp 52, which can be engaged on a support element 42 in its thickness, the barrel 55 coming to position itself opposite pre-drilling.
Les côtés latéraux 56 de l'embase 10 comportent de préférence des cloisons 69, pourvues d'au moins un perçage 70 de passage d'un élément de fixation sur le carter 2 tel qu'une vis ou un rivet. Les éléments de support 42 peuvent comporter des préperçages en excès, de telle sorte que la boîte à bornes 3 peut facilement accueillir des modules électroniques 20 de tailles différentes, selon une grande variété d'agencement. The lateral sides 56 of the base 10 preferably comprise partitions 69, provided with at least one piercing hole 70 for passing a fixing element on the casing 2 such as a screw or a rivet. The support members 42 may have excessive pre-drills, so that the terminal box 3 can easily accommodate electronic modules 20 of different sizes, in a wide variety of arrangements.
Des agencements possibles sont illustrés sur les figures 3A, 3B et 3C : la même embase 10 accueille sur les figures 3 A et 3B un seul module 20, tandis qu'elle en accueille deux sur la figure 3C. De plus, cette même embase 10 accueille un module électronique 20 représenté sur la figure 3A qui diffère, notamment de par sa taille, de celui représenté sur la figure 3B. Les éléments de support 42i, 42j, 42k et un élément de support non visible sur la figure 4, servant à la fixation du module 20 de la figure 3A, sont différents des éléments de support 42r et 42s servant à la fixation du module 20 de la figure 3B.  Possible arrangements are illustrated in Figures 3A, 3B and 3C: the same base 10 accommodates in Figures 3A and 3B a single module 20, while it accommodates two in Figure 3C. In addition, this same base 10 accommodates an electronic module 20 shown in Figure 3A which differs, in particular by its size, that shown in Figure 3B. The support elements 42i, 42j, 42k and a support element that is not visible in FIG. 4, for fixing the module 20 of FIG. 3A, are different from the support elements 42r and 42s used for fixing the module 20 of FIG. Figure 3B.
L'embase est de préférence symétrique par rapport à un plan médian longitudinal comportant l'axe X.  The base is preferably symmetrical with respect to a longitudinal median plane including the X axis.
De préférence également, comme illustré, les côtés latéraux 56 de l'embase 10 ainsi que les montants avant et arrière 51 comportent des logements 53 permettant d'accueillir des écrous à pince 50 servant au montage des différents éléments constitutifs du capot 11. Les côtés latéraux 56 peuvent également comporter chacun un décrochement 72 permettant de positionner sur l'embase l'un des panneaux latéraux 14 et 15. Il en est de même des côtés avant et arrière qui présentent chacun un décrochement 72 pour le positionnement de l'un des panneaux avant et arrière 16 et 17, la profondeur de ces décrochements 72 correspondant sensiblement à l'épaisseur des panneaux.  Also preferably, as illustrated, the lateral sides 56 of the base 10 as well as the front and rear uprights 51 comprise housings 53 for receiving clamp nuts 50 for mounting the various components of the cover 11. The sides lateral 56 may also each comprise a recess 72 for positioning on the base one of the side panels 14 and 15. It is the same for the front and rear sides each having a recess 72 for the positioning of one of the front and rear panels 16 and 17, the depth of these recesses 72 corresponding substantially to the thickness of the panels.
Les côtés latéraux 56 ainsi que les montants avant et arrière 51 sont moulés d'une seule pièce avec le reste de l'embase 10.  The lateral sides 56 as well as the front and rear uprights 51 are molded in one piece with the rest of the base 10.
Les éléments de support des côtés latéraux 56 peuvent porter des pattes 80 pourvues chacune d'un perçage 81, destinées à la fixation d'un module, et dirigées vers le plan médian longitudinal de l'embase 10.  The support elements of the lateral sides 56 may carry lugs 80, each provided with a bore 81, intended to fix a module, and directed towards the longitudinal median plane of the base 10.
Dans un exemple d'agencement, la zone de fixation 25, et par symétrie, le cas échéant, également la zone de fixation 24, comporte plusieurs nervures transversales 44, pouvant avoir des largeurs différentes, ainsi qu'au moins une nervure longitudinale 46.  In an exemplary arrangement, the attachment zone 25, and by symmetry, where appropriate, also the attachment zone 24, has several transverse ribs 44, which may have different widths, as well as at least one longitudinal rib 46.
La zone de fixation 25, et par symétrie, le cas échéant, également la zone de fixation 24, peut comporter au moins deux sous-zones de fixation de modules électroniques 20, chacune des sous-zones pouvant comporter un agencement d'éléments de support 20 qui lui est propre. Par exemple la sous-zone située le plus à droite de la figure 4 comporte trois rails longitudinaux prépercés, tandis que la sous-zone située le plus à gauche de cette même figure n'en comporte que deux, celui du milieu n'étant pas prépercé. The fixing zone 25, and by symmetry, if necessary, also the fixing zone 24, may comprise at least two electronic module attachment sub-zones 20, each of the sub-zones possibly comprising an arrangement of support elements. 20 of its own. For example, the rightmost subfield of Figure 4 has three pre-drilled longitudinal rails, while the left-most sub-zone of this same figure has only two, the middle one being not pre-drilled.
Comme illustré sur la figure 4, les surfaces 42 de réception des écrous à pince 50 d'un rail peuvent être adjacentes les unes aux autres ou bien être séparées les unes des autres par exemple par une nervure ou par une cloison, ceci de manière potentiellement différente d'un rail à l'autre.  As illustrated in FIG. 4, the surfaces 42 for receiving the collet nuts 50 of a rail may be adjacent to each other or may be separated from each other for example by a rib or a partition, this potentially different from one rail to another.
Les éléments de support 42 situés du côté du montant 51 le plus à gauche sur la figure 4 sont reliés entre eux par un élément de jonction 83 qui s'étend selon un plan perpendiculaire à l'axe X, cet élément de jonction 83 étant moulé d'une seule pièce avec le reste de l'embase 10.  The support members 42 located on the side of the leftmost post 51 in FIG. 4 are interconnected by a connecting element 83 which extends in a plane perpendicular to the axis X, this connecting element 83 being molded in one piece with the rest of the base 10.
Comme on le voit sur la figure 1, une fois le capot 11 assemblé, le couvercle 13 vient recouvrir les différents panneaux 14 à 17 à leur partie supérieure, sans toutefois empêcher leur démontage de façon individuelle.  As can be seen in FIG. 1, once the hood 11 has been assembled, the cover 13 covers the various panels 14 to 17 at their upper part, without however preventing their disassembly individually.
Chaque panneau latéral 14 ou 15 peut comporter un perçage 60 pour le passage d'une vis qui se visse sur le panneau adjacent avant ou arrière 16 ou 17, dans un perçage correspondant 61 de ce panneau avant ou arrière.  Each side panel 14 or 15 may include a bore 60 for the passage of a screw which is screwed to the front or rear adjacent panel 16 or 17, in a corresponding bore 61 of the front or rear panel.
De même, le couvercle 13 comporte des perçages 63 pour le passage de vis qui s'engagent dans des perçages correspondants 65 des panneaux avant et arrière 16 ou 17. Pour assembler la boîte à bornes 3, on commence par fixer l'embase 10 sur le carter 2 de la machine 1, à l'aide par exemple de vis engagées dans des perçages 37 des pattes 36 ainsi éventuellement que dans les perçages 70 de l'embase 10.  Similarly, the cover 13 has holes 63 for the passage of screws which engage in corresponding holes 65 of the front and rear panels 16 or 17. To assemble the terminal box 3, we first fix the base 10 on the housing 2 of the machine 1, for example using screws engaged in holes 37 of the tabs 36 and possibly in the holes 70 of the base 10.
Ensuite, le ou les modules électroniques 20 peuvent être fixés sur l'embase 10 grâce aux éléments de fixation, par exemple des écrous à pince 50, leur positionnement étant choisi de façon à faciliter leur implantation et la maintenance de la machine. Les câbles sont connectés à l'aide de cosses engagées sur des goujons vissés dans les inserts 22, et maintenus sur les goujons à l'aide d'écrous. Les goujons sont de préférence des vis sans tête Hc. Après assemblage des différents composants à l'intérieur de la boîte à bornes 3, le capot 11 peut être mis en place, étant par exemple pré-assemblé pas vissage du couvercle 13 sur les panneaux 14 à 17, puis fixé sur l'embase 10. De préférence, les différents éléments du capot 11 sont métalliques mais on ne sort pas du cadre de la présente invention lorsque le capot est réalisé avec des éléments non métalliques. Le cas échéant, le capot 11 peut être réalisé de façon monobloc avec les différents panneaux et le couvercle. Then, the electronic module or modules 20 can be fixed on the base 10 by means of the fastening elements, for example clamp nuts 50, their positioning being chosen so as to facilitate their implementation and maintenance of the machine. The cables are connected using lugs engaged on studs screwed into the inserts 22, and held on the studs with nuts. The studs are preferably Hc screws. After assembly of the various components inside the terminal box 3, the cover 11 can be put in place, for example by being pre-assembled by screwing the cover 13 onto the panels 14 to 17, then fixed on the base 10 Preferably, the various elements of the cover 11 are metallic but it is not beyond the scope of the present invention when the cover is made with non-metallic elements. Where appropriate, the cover 11 can be made in one piece with the different panels and the cover.
On ne sort pas du cadre de la présente invention en apportant diverses modifications à l'exemple qui vient d'être décrit.  It is not beyond the scope of the present invention by making various modifications to the example just described.
Par exemple, on peut modifier l'emplacement de la zone de raccordement électrique au sein de l'embase, et faire en sorte que cette zone de raccordement ne soit plus centrale.  For example, we can change the location of the electrical connection area within the base, and ensure that this connection area is no longer central.
L'expression « comportant un » doit se comprendre comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.  The expression "comprising one" must be understood as being synonymous with "having at least one" unless the contrary is specified.
