Abstract
Description
La présente invention est relative à un assemblage de borne connexion sur un alternateur ou un alterno-démarreur de véhicule, notamment automobile. The present invention relates to a connection terminal assembly on an alternator or an alternator-starter of a vehicle, in particular an automobile.
Classiquement, le palier arrière d'un alternateur porte ou plusieurs radiateurs qui portent) des diodes d'un pont redresseur de sortie. Ce palier arrière porte en outre une borne, appelée B+, pour la connexion à la sortie redressée de l'alternateur, ainsi qu'une platine, dite porte-balais, qui comporte des logements pour recevoir les balais l'alternateur. Une pièce formant connecteur permet de distribuer les potentiels de phase en sortie des bobinages statoriques de l'alternateur sur les diodes positives et négatives portées par le les radiateurs. Conventionally, the rear bearing of an alternator carries or several radiators which carry) diodes of an output rectifier bridge. This rear bearing further carries a terminal, called B +, for connection to the rectified output of the alternator, as well as a plate, called a brush holder, which comprises housings for receiving the brushes of the alternator. A piece forming a connector makes it possible to distribute the phase potentials at the output of the stator windings of the alternator on the positive and negative diodes carried by the radiators.
Dans certaines structures, la platine porte-balais porte tout ou partie d'une électronique de régulation de la tension de sortie de l'alternateur. In some structures, the brush holder plate carries all or part of an electronic regulator for the alternator output voltage.
Généralement, la platine porte-balais est alors reliée a la borne B+ par une connexion qui est ménagée spécifiquement ' cet effet et qui s'étend entre la borne B+ et la platine porte-balais. Generally, the brush holder plate is then connected to the B + terminal by a connection which is specifically provided for this purpose and which extends between the B + terminal and the brush holder plate.
Cette connexion est par exemple portée par la pièce formant connecteur, le contact électrique entre cette connexion et la borne B+ étant assuré par le vissage ou le sertissage de celle-ci sur ladite pièce formant collecteur. This connection is for example carried by the piece forming a connector, the electrical contact between this connection and the terminal B + being ensured by screwing or crimping the latter on said piece forming a collector.
Un but de l'invention est de proposer un assemblage d'une structure simplifiée et d'une fiabilité accrue. An object of the invention is to propose an assembly of a simplified structure and of increased reliability.
A cet effet, l'invention propose un assemblage pour palier d'alternateur de véhicule, notamment automobile, comportant une borne pour la connexion à la sortie redressée de l'alternateur une platine porte-balais, au moins un radiateur sur lequel est monté un jeu de diodes et qui est en contact électrique avec la borne de connexion, caractérisé en ce que la platine porte balais et le radiateur présentent des formes complémentaires qui assurent un contact électrique direct entre ladite platine et ledit radiateur. Ainsi, le contact électrique entre la borne de connexion et la platine porte-balais est assuré directement par la complémentarité des formes de platine porte-balais et du radiateur. To this end, the invention provides an assembly for a bearing of a vehicle alternator, in particular an automobile, comprising a terminal for connection to the rectified output of the alternator, a brush holder plate, at least one radiator on which is mounted a set of diodes and which is in electrical contact with the connection terminal, characterized in that the brush holder plate and the radiator have complementary shapes which ensure direct electrical contact between said plate and said radiator. Thus, the electrical contact between the connection terminal and the brush holder plate is ensured directly by the complementarity of the brush holder plate and radiator shapes.
II résulte une réduction de pièce et par conséquent une simplification de montage et une plus grande fiabilité. This results in a reduction in part and therefore a simplification of assembly and greater reliability.
En outre, avantageusement, cet assemblage est caractérisé en ce que la borne de connexion est une pièce qui présente un corps de révolution et une tête, ladite pièce traversant le radiateur, sa tête étant reçue dans un logement qui débouche au niveau du fond du radiateur et qui est d'une forme qui est complémentaire à celle de la tête et qui empêche la rotation de ladite borne de connexion autour de son axe. In addition, advantageously, this assembly is characterized in that the connection terminal is a part which has a body of revolution and a head, said part passing through the radiator, its head being received in a housing which opens out at the bottom of the radiator. and which is of a shape which is complementary to that of the head and which prevents the rotation of said connection terminal around its axis.
Une telle structure présente alors l'avantage de permettre d'assurer contact électrique entre la borne de connexion et la platine porte-balais sans qu'un vissage ou un sertissage de la borne de connexion soit nécessaire. Such a structure then has the advantage of making it possible to ensure electrical contact between the connection terminal and the brush holder plate without any screwing or crimping of the connection terminal being necessary.
L'invention est avantageusement complétée par les différentes caractéristiques suivantes prises seules ou selon toutes leurs combinaisons techniquement possibles - formes complémentaires de la platine et du radiateur comportent plot de centrage et un trou complémentaire ; - le plot de centrage est traversé par un orifice destiné à recevoir des moyens aptes à contribuer ou à assurer la fixation de la platine sur le radiateur ; - il comporte une pièce formant connecteur sur laquelle la platine porte-balais et le radiateur sont fixés au niveau de formes complémentaires qui assurent un contact électrique entre ladite platine et ledit radiateur ; - une couche en un matériau isolant est interposée entre la pièce formant connecteur et la platine ; - moyens aptes à être reçus dans le plot de centrage contribuent ' ou assurent la fixation de la platine et du radiateur sur la pièce formant connecteur. L'invention concerne également un alternateur ou un alterno- démarreur comportant un assemblage du type de ceux ci-dessus mentionnés. The invention is advantageously supplemented by the following different characteristics taken alone or in all their technically possible combinations - complementary shapes of the plate and of the radiator comprise centering stud and a complementary hole; - The centering stud is crossed by an orifice intended to receive means capable of contributing to or ensuring the fixing of the plate on the radiator; - It comprises a part forming a connector on which the brush holder plate and the radiator are fixed at the level of complementary forms which ensure electrical contact between said plate and said radiator; - a layer of insulating material is interposed between the connector part and the plate; - Means capable of being received in the centering stud contribute 'or ensure the fixing of the plate and the radiator on the part forming the connector. The invention also relates to an alternator or an alternator-starter comprising an assembly of the type of those mentioned above.
On rappelle que le terme alterno-démarreur désigne, de façon désormais classique pour l'homme du métier, toute machine électrique apte à être utilisée aussi bien comme générateur que comme moteur électrique. It will be recalled that the term alternator-starter designates, from now on in a conventional manner for those skilled in the art, any electric machine capable of being used both as a generator and as an electric motor.
D'autres caractéristiques et avantages de l'invention ressortiront encore de la description qui suit. Cette description est purement illustrative et non limitative et doit être lue en regard des dessins annexés sur lesquels - la figure 1 est une représentation schématique en coupe d'un assemblage conforme à un mode de réalisation de l'invention ; - la figure 2 est une représentation schématique en vue de dessus du radiateur de l'assemblage de la figure 1. Other characteristics and advantages of the invention will emerge from the description which follows. This description is purely illustrative and not limiting and should be read with reference to the accompanying drawings in which - Figure 1 is a schematic sectional representation of an assembly according to an embodiment of the invention; - Figure 2 is a schematic representation in top view of the radiator of the assembly of Figure 1.
L'assemblage illustré sur les figures 1 et 2 comporte une borne de connexion B+, une pièce 2 qui forme radiateur métallique et qui porte des diodes 3, ainsi qu' platine 4 qui porte un manchon 4a formant un moyen de protection pour un connecteur et qui comporte également des moyens de connexion 4b auxquels une unité de gestion qui comporte des moyens de régulation est destinée à être raccordée. L'assemblage comporte en outre une pièce 5 formant connecteur. The assembly illustrated in FIGS. 1 and 2 comprises a connection terminal B +, a part 2 which forms a metallic radiator and which carries diodes 3, as well as plate 4 which carries a sleeve 4a forming a protection means for a connector and which also includes connection means 4b to which a management unit which includes regulation means is intended to be connected. The assembly further comprises a part 5 forming a connector.
La borne B+ est constituee par une vis 1 dont la tête 1 a est une tête de type six pans. The terminal B + is constituted by a screw 1, the head 1 a of which is a hexagonal type head.
Cette vis 1 traverse le radiateur 2. Plus précisément, la tête 1 a de la vis est reçue dans un logement 2a de forme complémentaire qui débouche au niveau du fond du radiateur 2 (c'est à dire de la surface du radiateur 2 qui est destinée à être en regard de la pièce 5 formant connecteur). A son extremité opposée audit fond, les parois de ce logement 2a se prolongent un manchon 2b dont le diamètre interne correspond sensiblement diamètre externe du corps de la vis 1 et qui est destiné à recevoir celui-ci. Lorsque la vis 1 est en place dans le logement 2a et manchon 2b, son corps est sur environ la moitié de sa hauteur saillie à l'extérieur du manchon 2b. This screw 1 passes through the radiator 2. More precisely, the head 1a of the screw is received in a housing 2a of complementary shape which opens at the bottom of the radiator 2 (that is to say of the surface of the radiator 2 which is intended to be opposite part 5 forming a connector). At its end opposite to said bottom, the walls of this housing 2a extend a sleeve 2b whose internal diameter corresponds substantially to the external diameter of the body of the screw 1 and which is intended to receive the latter. When the screw 1 is in place in the housing 2a and sleeve 2b, its body is over about half of its height protruding outside the sleeve 2b.
En outre, la vis 1 est alors empêchée de tourner sur elle même par la forme du logement 2a, dont les parois bloquent les pans de la tête la. In addition, the screw 1 is then prevented from turning on itself by the shape of the housing 2a, the walls of which block the sides of the head 1a.
Une fois la vis 1 positionnée sur le radiateur 2, celui-ci est fixe par vissage avec la platine 4 porte-balais sur la pièce 5 qui forme connecteur et sur le palier de l'alternateur. Once the screw 1 positioned on the radiator 2, it is fixed by screwing with the plate 4 brush holder on the part 5 which forms a connector and on the bearing of the alternator.
Plus précisément, le radiateur 2 présente, au voisinage logement 2a et du manchon 2b destinés à recevoir la borne B+, prolongement 6 sur lequel la platine 4 porte-balais est destinée à venir en appui. More specifically, the radiator 2 has, in the vicinity of housing 2a and of the sleeve 2b intended to receive the terminal B +, extension 6 on which the plate 4 brush holder is intended to come to bear.
Ce prolongement 6 présente un orifice de centrage 7 destiné à recevoir un plot de centrage 8 complémentaire que présente la platine 4 porte balais. This extension 6 has a centering orifice 7 intended to receive a complementary centering stud 8 presented by the plate 4 brush holder.
Ce plot de centrage 8 est lui-même traversé par un orifice 9 destiné à recevoir le corps d'une vis (non représentée) qui s'étend à travers pièce 5 formant connecteur et ledit plot de centrage 8 et qui coopère avec un écrou complémentaire pour assurer la fixation du radiateur 2 et de la platine porte-balais 4 sur la pièce 5 formant connecteur. This centering stud 8 is itself traversed by an orifice 9 intended to receive the body of a screw (not shown) which extends through piece 5 forming a connector and said centering stud 8 and which cooperates with a complementary nut to secure the radiator 2 and the brush holder plate 4 on the part 5 forming a connector.
Avec un tel montage, la platine porte-balais est en contact électrique avec le radiateur 2 par les zones par laquelle elle est en appui sur les bords qui, sur le prolongement 6, définissent l'orifice de centrage 7. With such an assembly, the brush-holder plate is in electrical contact with the radiator 2 by the zones by which it bears on the edges which, on the extension 6, define the centering orifice 7.
Une couche électriquement isolante est interposée entre la pièce 5 formant connecteur et la platine 4 pour éviter les courts circuits entre les deux.An electrically insulating layer is interposed between the part 5 forming a connector and the plate 4 to avoid short circuits between the two.
