L'invention concerne plus particulièrement un alternateur pour véhicule automobile du type comportant une plaque porte-balais réalisée en matériau isolant et fixée sur un palier arrière de l'alternateur en matériau conducteur, du type comportant un régulateur électronique de tension contenu dans un boîtier fixé contre la plaque porte-balais et dont les plots de raccordement s'étendent axialement au travers d'un orifice de la plaque porte-balais pour venir en contact de conducteurs métalliques qui sont intégrés dans la plaque portebalais et dont des extrémités débouchent dans une paroi de l'orifice, et du type dans lequel le boîtier du régulateur ferme l'orifice à l'une de ses extrémités axiales. The invention relates more particularly to an alternator for a motor vehicle of the type comprising a brush holder plate made of insulating material and fixed to a rear bearing of the alternator of conductive material, of the type comprising an electronic voltage regulator contained in a fixed housing against the brush holder plate and whose connection pads extend axially through an orifice in the brush holder plate to come into contact with metallic conductors which are integrated in the brush holder plate and whose ends open into a wall of the orifice, and of the type in which the regulator housing closes the orifice at one of its axial ends.
Un tel agencement d'un régulateur est connu et est décrit et représenté dans le document EP-A-484.287
Selon une telle conception de l'agencement d'un régulateur, ses bornes de raccordement se trouvent exposées à l'air libre.Such an arrangement of a regulator is known and is described and represented in document EP-A-484.287
According to such a design of the arrangement of a regulator, its connection terminals are exposed to the open air.
I1 a été proposé, afin de protéger les bornes, notamment de l'oxydation, de les noyer dans une résine synthétique. It has been proposed, in order to protect the terminals, in particular from oxidation, to drown them in a synthetic resin.
Toutefois, cette opération doit être impérativement réalisée après le montage du régulateur sur la plaque portebalais mais avant le montage de la plaque porte-balais sur le palier arrière de l'alternateur. However, this operation must imperatively be carried out after mounting the regulator on the brush holder plate but before mounting the brush holder plate on the rear bearing of the alternator.
De plus, le régulateur est fixé sur la plaque portebalais par deux rivets et la mise à la masse électrique du régulateur s'effectue indirectement par l'utilisation d'un conducteur métallique intégré à la plaque porte-balais. In addition, the regulator is fixed to the brush holder plate by two rivets and the electric grounding of the regulator is carried out indirectly by the use of a metallic conductor integrated into the brush holder plate.
Afin d'apporter une réponse à ces problèmes, l'invention propose un alternateur du type vu précédemment, caractérisé en ce que l'orifice de la plaque porte-balais est agencé en regard de l'ouverture d'un logement borgne du palier arrière de manière à délimiter, avec le régulateur, un logement étanche dans lequel sont reçus les plots de raccordement du régulateur. In order to provide an answer to these problems, the invention proposes an alternator of the type seen above, characterized in that the orifice of the brush holder plate is arranged opposite the opening of a blind housing of the rear bearing. so as to define, with the regulator, a sealed housing in which are received the connection pads of the regulator.

- le régulateur est fixé contre la plaque porte-balais par des éléments de fixation en matériau conducteur, qui coopèrent avec le palier arrière pour assurer la mise à la masse électrique du régulateur
- les éléments de fixation sont des vis reçues au travers d'orifices percés dans le boîtier métallique du régulateur, elles traversent la plaque porte-balais et sont vissées dans le palier arrière
- la plaque porte-balais comporte des moyens pour sa fixation sur le palier arrière indépendants des vis de fixation du régulateur.According to other features of the invention
- there is a seal arranged between the rear bearing and the brush holder plate, around the opening of the housing
- the regulator is fixed against the brush holder plate by fixing elements made of conductive material, which cooperate with the rear bearing to ensure the electric grounding of the regulator
- the fastening elements are screws received through holes drilled in the metal housing of the regulator, they pass through the brush holder plate and are screwed into the rear bearing
- The brush holder plate includes means for fixing it to the rear bearing independent of the regulator fixing screws.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels
- La figure 1 est une vue en coupe suivant la ligne 11 de la figure 2 d'un palier arrière d'alternateur équipé d'une plaque porte-balais et d'un régulateur conformément aux enseignements de l'invention
- la figure 2 est une vue partielle de face d'un tel palier arrière.Other characteristics and advantages of the invention will appear on reading the following detailed description for the understanding of which reference will be made to the accompanying drawings in which

On a représenté sur les figures 1 et 2 un palier arrière 10 d'un alternateur pour véhicule automobile (non représenté). There is shown in Figures 1 and 2 a rear bearing 10 of an alternator for a motor vehicle (not shown).
Le palier arrière 10 ferme une extrémité axiale de l'alternateur sur lequel il est fixé par des vis 12. The rear bearing 10 closes an axial end of the alternator to which it is fixed by screws 12.
Le palier 10 comporte, sur une face externe 14, un bossage 16 sur la face supérieure duquel est agencée une plaque porte-balais 18. The bearing 10 comprises, on an external face 14, a boss 16 on the upper face of which a brush-carrying plate 18 is arranged.
La plaque porte-balais 18 est fixée sur le bossage 16 par une vis 20 et comporte un orifice 22, sensiblement circulaire, agencé en regard d'un logement cylindrique borgne 24 agencé dans le bossage 16 du palier arrière 10. The brush holder plate 18 is fixed to the boss 16 by a screw 20 and comprises a substantially circular orifice 22, arranged opposite a blind cylindrical housing 24 arranged in the boss 16 of the rear bearing 10.
La plaque porte-balais 18 porte, outre des balais 26 protégés par un capuchon 28, des accessoires tels qu'un condensateur 30, une borne de raccordement 32 et un régulateur électronique de tension 34. The brush holder plate 18 carries, in addition to the brushes 26 protected by a cap 28, accessories such as a capacitor 30, a connection terminal 32 and an electronic voltage regulator 34.
Le régulateur 34 se présente sous la forme d'un boîtier métallique cylindrique de faible hauteur qui est en appui par un flan transversal métallique 36 contre la plaque porte-balais 18, au-dessus de l'orifice 22 en regard du logement 24 du palier 10. The regulator 34 is in the form of a cylindrical metal case of low height which is supported by a metal transverse blank 36 against the brush holder plate 18, above the orifice 22 opposite the housing 24 of the bearing 10.
Le régulateur 34 porte, sur sa face d'extrémité axiale 50 qui est en regard du palier 10, une série de plots de raccordement 38 disposés axialement selon un cercle de diamètre inférieur à celui de l'orifice 22 et du logement 24. The regulator 34 carries, on its axial end face 50 which faces the bearing 10, a series of connection pads 38 arranged axially in a circle with a diameter smaller than that of the orifice 22 and of the housing 24.
Les plots 38 s'étendent à l'intérieur du logement 24 qui est fermé par le régulateur électronique 34. The studs 38 extend inside the housing 24 which is closed by the electronic regulator 34.
Les plots de raccordement 38 sont en contact avec l'extrémité débouchante de conducteurs métalliques 40 qui sont noyés dans la plaque porte-balais 18 et qui permettent le raccordement du régulateur 34 aux différents accessoires agencés sur la plaque porte-balais 18 et au circuit électrique du véhicule. The connection pads 38 are in contact with the through end of metallic conductors 40 which are embedded in the brush holder plate 18 and which allow the regulator 34 to be connected to the various accessories arranged on the brush holder plate 18 and to the electrical circuit. of the vehicle.
Un joint 42 est par ailleurs prévu entre la plaque porte-balais 18 et le palier arrière 10, autour de l'orifice 22 afin d'assurer l'étanchéité du logement 24. A seal 42 is also provided between the brush holder plate 18 and the rear bearing 10, around the orifice 22 in order to seal the housing 24.
Le flan transversal métallique 36 du régulateur 34 comporte deux oreilles 44 percées pour le passage de vis 46 de fixation du régulateur 34. The metal transverse blank 36 of the regulator 34 has two ears 44 pierced for the passage of screws 46 for fixing the regulator 34.
