Description

"Boîtier pour le raccordement électrique de câbles à haute tension" DOMAINE TECHNIQUE DE L'INVENTION La présente invention concerne un boîtier pour le raccordement électrique de plusieurs câbles électriques à haute tension dans le compartiment moteur d'un véhicule automobile. On rappelle que dans le domaine technique considéré, à savoir celui de l'automobile, la plage de la haute tension va de 60 à 600 volts.  FIELD OF THE INVENTION The present invention relates to a housing for the electrical connection of several high voltage electrical cables in the engine compartment of a motor vehicle. It is recalled that in the technical field considered, namely that of the automobile, the range of the high voltage ranges from 60 to 600 volts.
L'invention concerne notamment un boîtier pour le raccordement de divers composants appartenant par exemple à un circuit de refroidissement (par exemple un compresseur et une bouilloire), et un bloc électronique de puissance (PEB) assurant des fonctions d'électronique de puissance et notamment d'onduleur pour piloter la machine et de conversion d'une source de courant continu d'un niveau de tension à un autre.  The invention relates in particular to a housing for connecting various components belonging for example to a cooling circuit (for example a compressor and a kettle), and an electronic power unit (PEB) providing power electronics functions and in particular inverter to drive the machine and to convert a DC power source from one voltage level to another.
ETAT DE LA TECHNIQUE STATE OF THE ART
On connaît différentes conceptions d'un boîtier pour le raccordement électrique d'au moins deux câbles électriques à haute tension comportant chacun au moins deux fils conducteurs isolés de phases électriques différentes, l'extrémité libre de chaque conducteur électrique étant munie d'une cosse de raccordement électrique à œillet, le boîtier comportant une plaque support isolante de l'électricité qui porte des tiges filetées parallèles en matériau conducteur de l'électricité dont chacune est équipée d'un moyen de serrage axial. Various designs of a housing are known for the electrical connection of at least two high-voltage electrical cables each comprising at least two insulated conductor wires of different electrical phases, the free end of each electrical conductor being provided with a terminal lug. electrical connection to eyelet, the housing comprising an electrically insulating support plate which carries parallel threaded rods of electrically conductive material each of which is equipped with an axial clamping means.
Selon ces conceptions, par exemple pour le raccordement électrique de trois câbles comportant chacun deux conducteurs électriques, la plaque support en matériau isolant porte six tiges filetées dont chacune est munie d'un écrou de serrage axial d'une cosse à œillet, c'est à dire que chaque extrémité libre d'un conducteur électrique est fixée et reliée électriquement individuellement à une tige filetée associée. According to these designs, for example for the electrical connection of three cables each having two electrical conductors, the support plate of insulating material carries six threaded rods, each of which is provided with an axial clamping nut of an eyelet terminal, it is to say that each free end of an electrical conductor is fixed and electrically connected individually to an associated threaded rod.
Pour relier entre eux les trois conducteurs de même phase électrique, le boîtier comporte des moyens de raccordement électrique des trois tiges filetées associées qui sont par exemples des bandes de cuivre, aussi appelées "busbars", de section suffisante et qui comportent chacune des trous traversés par les tiges filetées, les œillets des cosses de raccordement électriques étant serrés en contact électrique avec la ou les bandes conductrices au moyen des écrous.  To connect together the three conductors of the same electrical phase, the housing comprises means for electrical connection of the three associated threaded rods which are for example copper strips, also called "busbars", of sufficient cross section and which each comprise through holes by the threaded rods, the eyelets of the electrical connection lugs being tight in electrical contact with the conductive strip or strips by means of the nuts.
Une telle conception est complexe, fait appel à un grand nombre de composants à assembler et est de plus très encombrante du fait de la nécessité d'agencer les bandes conductrices en évitant aussi les phénomènes de court-circuits et d'arcs électriques entre les différentes phases.  Such a design is complex, uses a large number of components to assemble and is also very cumbersome because of the need to arrange the conductive strips also avoiding the phenomena of short circuits and arcing between the different phases.
Cet encombrement est d'autant plus important si l'on souhaite que, pour des facilités d'aménagement dans le compartiment moteur, toutes les "sorties" des câbles hors du boîtier soient regroupées dans une même zone et/ou une même face du boîtier.  This size is all the more important if it is desired that, for ease of arrangement in the engine compartment, all the "outputs" of the cables out of the housing are grouped in the same area and / or the same face of the housing .

On a représenté aux figures un boîtier 10 de raccordement électrique constitué pour l'essentiel par un corps 12 et un capot ou couvercle 14.  The figures show a box 10 of electrical connection consisting essentially of a body 12 and a cover or cover 14.
Le boîtier 10 permet ici le raccordement électrique simultané de trois câbles électriques Ci à haute tension C1, C2 et C3.  The housing 10 here allows the simultaneous electrical connection of three electric cables Ci high voltage C1, C2 and C3.
Chaque câble électrique Ci comporte ici deux conducteurs électriques de phases différentes Fi+ et Fi-.  Each electrical cable Ci here comprises two electrical conductors of different phases Fi + and Fi-.
Ainsi, le premier câble électrique C1 comporte deux conducteurs F1+ et F1-, le deuxième câble électrique C2 comporte deux conducteurs F2+ et F2-, et le troisième câble électrique C3 comporte deux conducteurs F3+ et F3-.  Thus, the first electrical cable C1 comprises two conductors F1 + and F1-, the second electrical cable C2 comprises two conductors F2 + and F2-, and the third electrical cable C3 comprises two conductors F3 + and F3-.
Chaque câble Ci est ici de conception analogue et il comporte une gaine externe Gi dans laquelle sont logés les deux conducteurs électriques Fi+ et Fi-.  Each cable Ci is here of similar design and it comprises an outer sheath Gi in which are housed the two electrical conductors Fi + and Fi-.
Chaque conducteur Fi + , Fi- est isolé électriquement de l'autre conducteur électrique associé Fi-, Fi+ et chacun comporte, à son extrémité libre agencée à l'intérieur du boîtier 10, une borne de raccordement ici sous la forme d'une cosse de raccordement électrique à œillet Bi + , Bi- respectivement.  Each conductor Fi +, Fi- is electrically isolated from the other associated electrical conductor Fi-, Fi + and each has, at its free end arranged inside the housing 10, a connection terminal here in the form of a terminal Bi +, Bi-, respectively, electrical connection connection.
Chaque cosse Bi+ est reliée électriquement à l'âme conductrice du conducteur électrique associé Fi + , tandis que chaque cosse Bi- est reliée électriquement à l'âme conductrice du conducteur électrique associé Fi-. Each lug Bi + is electrically connected to the conductive core of the associated electrical conductor Fi +, while each lug Bi- is electrically connected to the conductive core of the associated electrical conductor Fi-.
Le corps principal 14 est une pièce moulée en matière plastique isolante de l'électricité et elle comporte essentiellement une plaque verticale de support 18, et une paroi inférieure horizontale 20.  The main body 14 is an electrically insulating plastic molded part and essentially comprises a vertical support plate 18 and a horizontal bottom wall 20.
La plaque support 18 comporte une face avant 22 d'orientation verticale et longitudinale, et une face arrière parallèle et opposée 24.  The support plate 18 comprises a front face 22 of vertical and longitudinal orientation, and a parallel and opposite rear face 24.
La plaque support 18 est de forme générale rectangulaire délimitée par un bord supérieur horizontal 28 et par deux bords verticaux opposés 30 et 32.  The support plate 18 is of generally rectangular shape delimited by a horizontal upper edge 28 and by two opposite vertical edges 30 and 32.
La paroi inférieure 20 est délimitée par une face supérieure horizontale 34 et par une face inférieure parallèle et opposée 36 qui constitue la face d'appui et de fixation du boîtier de raccordement électrique 10.  The bottom wall 20 is delimited by a horizontal upper face 34 and by a parallel and opposite lower face 36 which constitutes the bearing and fixing face of the electrical connection box 10.
Pour cette fixation, par exemple sur élément de caisse de véhicule automobile, la paroi inférieure 20 comporte deux oreilles longitudinales opposées 38.  For this attachment, for example on a motor vehicle body element, the bottom wall 20 has two opposite longitudinal lugs 38.
La plaque support 18 est décalée transversalement vers l'arrière par rapport au plan vertical médian de la paroi inférieure The support plate 18 is shifted transversely rearward with respect to the median vertical plane of the lower wall

La paroi inférieure comporte trois trous verticaux débouchant Ti dont chacun est dimensionné pour permettre le passage d'un câble électrique associé Ci  The bottom wall has three vertical holes opening Ti each of which is sized to allow the passage of an associated electrical cable Ci
Au niveau de son raccordement avec la face supérieure 34 de la paroi inférieure 20, la plaque de support 18 comporte un bloc inférieur avant en surépaisseur 40 et un bloc inférieur arrière en surépaisseur 42.  At its connection with the upper face 34 of the lower wall 20, the support plate 18 comprises a lower front block in excess of thickness 40 and a rear lower block in extra thickness 42.
Le bloc avant 40 comporte un logement concave semi- cylindrique L1 apte à recevoir la portion en vis-à-vis du câble C1 et un logement concave semi-cylindrique L2 apte à recevoir la portion en vis-à-vis du câble C2. Les deux logements L1 et L2 sont décalés longitudinalement et transversalement l'un par rapport à l'autre. The front block 40 comprises a semi-cylindrical concave housing L1 adapted to receive the portion facing the cable C1 and a semi-cylindrical concave housing L2 adapted to receive the portion vis-à-vis the cable C2. Both dwellings L1 and L2 are offset longitudinally and transversely relative to each other.
Le bloc arrière 42 comporte un logement concave semi- cylindrique L3 apte à recevoir la portion en vis-à-vis du câble C3. Le logement L3 est centré longitudinalement.  The rear block 42 has a semi-cylindrical concave housing L3 adapted to receive the portion facing the cable C3. The housing L3 is centered longitudinally.
Comme on peut le voir à titre d'exemple à la figure 3, il est possible de prévoir une plaque 44 de blocage et de fixation des câbles C1 et C2 au moyen de vis 46, pour éviter toute traction nuisible sur les cosses de raccordement Bi+ et Bi-. Un agencement analogue, non représenté, peut être prévu sur le bloc arrière 42. La plaque de blocage 44 peut être conductrice de l'électricité et assurer une fonction de mise à la terre, ou masse, du boîtier par l'intermédiaire d'une languette métallique 50 qui passe à travers une fente 52 de la paroi inférieure 20.  As can be seen by way of example in FIG. 3, it is possible to provide a plate 44 for blocking and fixing the cables C1 and C2 by means of screws 46, to avoid any detrimental traction on the Bi + connection lugs. and Bi-. A similar arrangement, not shown, may be provided on the rear block 42. The blocking plate 44 may be electrically conductive and provide a grounding function, or mass, of the housing through a metal tongue 50 which passes through a slot 52 of the bottom wall 20.
Conformément aux enseignements de l'invention, pour le raccordement électrique de tous les conducteurs Fi + , la plaque support 18 porte une seule tige filetée conductrice de l'électricité V+.  According to the teachings of the invention, for the electrical connection of all the conductors Fi +, the support plate 18 carries a single electrically conductive threaded rod V +.
Conformément aux enseignements de l'invention, pour le raccordement électrique de tous les conducteurs Fi-, la plaque support 18 porte une seule tige filetée conductrice de l'électricité V-.  According to the teachings of the invention, for the electrical connection of all the conductors Fi-, the support plate 18 carries a single electrically conductive threaded rod V-.
Les deux tiges filetées V+ et V- sont positionnées au voisinage du bord supérieur 28 de la plaque support 18.  The two threaded rods V + and V- are positioned in the vicinity of the upper edge 28 of the support plate 18.
Les deux tiges filetées V+ et V- sont décalées longitudinalement l'une par rapport à l'autre. La tige filetée V+ est sensiblement alignée avec le trou T1 tandis que la tige filetée est sensiblement alignée avec le trou T2.  The two threaded rods V + and V- are offset longitudinally relative to each other. The threaded rod V + is substantially aligned with the hole T1 while the threaded rod is substantially aligned with the hole T2.
Chaque tige filetée V+, s'étend transversalement à travers la plaque support 18 et elle comporte ainsi un tronçon avant et un tronçon arrière filetés opposés dont chacun est apte à traverser les œillets des cosses de raccordement Bi + , Bi- des conducteurs Fi + , Fi- correspondants et associés. Pour garantir les contacts électriques fiables et les fixations, chaque tronçon de tige filetée reçoit un écrou de serrage axial Ε+, E-. Each threaded rod V + extends transversely through the support plate 18 and thus comprises an opposite front section and a rear threaded section, each of which is capable of passing through the eyelets of the connecting terminals Bi +, Bi- of the conductors Fi +, Fi- correspondents and associates. To ensure reliable electrical contacts and fasteners, each threaded rod section receives an axial clamping nut Ε +, E-.
Selon la conception compacte et peu encombrante illustrée aux figures, deux câbles C1 et C2 sont agencés devant la face avant 22 avec leurs cosses B1+ et B2+ fixées sur la tige filetée V+, et avec leurs cosses B1- et B2- fixées sur la tige filetée V-.  According to the compact and space-saving design illustrated in the figures, two cables C1 and C2 are arranged in front of the front face 22 with their lugs B1 + and B2 + fixed on the threaded rod V +, and with their lugs B1- and B2- fixed on the threaded rod V-.
Le troisième câble C3 est agencé devant la face arrière 24 avec sa cosse B3+ fixée sur la tige filetée V+, et avec sa cosse B3- fixée sur la tige filetée V-.  The third cable C3 is arranged in front of the rear face 24 with its lug B3 + fixed on the threaded rod V +, and with its lug B3- fixed on the threaded rod V-.
Ainsi, tous les raccordements des trois câbles C1, C2 et C3 sont assurés au moyen de deux tiges filetées seulement, et ici au moyen de quatre écrous de serrage seulement.  Thus, all the connections of the three cables C1, C2 and C3 are ensured by means of two threaded rods only, and here by means of only four tightening nuts.
Toujours avec seulement deux tiges filetées V+ et V- et quatre écrous de serrage, avec de très légères modifications du bloc 12 (non représentées), mais dans le même encombrement, il est aisément possible de raccorder ici quatre câbles, deux sur la face avant 22 et deux sur la face arrière 24.  Always with only two threaded rods V + and V- and four clamping nuts, with very slight modifications of the block 12 (not shown), but in the same size, it is easily possible to connect here four cables, two on the front face 22 and two on the back side 24.
Les tiges filetées peuvent être associées chacune à une paire d'écrous comme représenté, ou bien appartenir chacune à une vis qui est alors associée à un seul écrou de serrage.  The threaded rods may each be associated with a pair of nuts as shown, or each belong to a screw which is then associated with a single clamping nut.
Chaque tige filetée peut être enfilée dans un trou de la plaque support 18 ou bien être fixée à celle-ci sous la forme d'un insert noyé par surmoulage.  Each threaded rod can be threaded into a hole of the support plate 18 or be fixed thereto in the form of an insert embedded by overmolding.
