Description

CONTACTEUR POUR UN DEMARREUR DE VEHICULE AUTOMOBILE CONTACTOR FOR A MOTOR VEHICLE STARTER
L'invention concerne un contacteur pour démarreur, notamment de véhicule automobile.The invention relates to a contactor for a starter, particularly a motor vehicle.
La demande de brevet US 2004/0169573 décrit un contacteur comportant un capot pourvu d'un passage de sortie d'un fil du bobinage. Un élément de contact est disposé sur une face extérieure du capot, le fil traversant le passage du capot étant soudé sur cet élément de contact.The patent application US 2004/0169573 discloses a contactor comprising a cover provided with an outlet passage of a winding wire. A contact element is disposed on an outer face of the cover, the wire passing through the passage of the cover being welded to this contact element.
L'invention vise à proposer un nouveau contacteur pour démarreur, notamment de véhicule automobile, comportant :The aim of the invention is to propose a novel starter contactor, particularly for a motor vehicle, comprising:
- au moins un bobinage d'excitation formé par au moins un fil électriquement conducteur,at least one excitation winding formed by at least one electrically conductive wire,
- au moins une cosse de connexion électrique comportant au moins une portion de connexion repliée par déformation autour d'une partie du fil du bobinage, la portion de connexion étant disposée dans un espace intérieur du contacteur.- At least one electrical connection lug having at least one folded connection portion deformation around a portion of the winding wire, the connecting portion being disposed in an interior of the contactor.
L'invention permet de réaliser, de manière mécanique, à savoir par sertissage, la connexion d'un ou de plusieurs fils du bobinage d'excitation avec une ou plusieurs cosses, sans risque de dommage ultérieur dû à l'environnement extérieur, par exemple sans risque d'oxydation, car ce ou ces fils restent protégés à l'intérieur du contacteur.The invention makes it possible, by mechanical means, namely by crimping, the connection of one or more son of the excitation coil with one or more terminals, without risk of subsequent damage due to the external environment, for example without risk of oxidation, because this or these son remain protected inside the contactor.
De plus la connexion d'un fil avec une cosse ne nécessite pas de soudure, et peut être ainsi relativement simple.In addition the connection of a wire with a lug does not require welding, and can be relatively simple.
Avantageusement la portion de connexion de la cosse comporte, d'une part, une branche d'extrémité sensiblement plane et, d'autre part, un ou plusieurs doigts se raccordant à la branche d'extrémité et repliés sur le fil conducteur, de manière à assurer la fixation du fil sur la cosse.Advantageously, the connecting portion of the lug comprises, on the one hand, a substantially flat end branch and, on the other hand, one or more fingers connecting to the end branch and bent over the conductor wire, to ensure the fixing of the wire on the pod.
De préférence, le contacteur comporte un capot séparant l'espace intérieur et l'extérieur du contacteur. Dans un exemple de mise en oeuvre de l'invention, le capot présente une face intérieure, et la cosse comporte une branche intermédiaire sensiblement plane et disposée contre la face intérieure du capot, la portion de connexion se raccordant à cette portion intermédiaire, notamment via un coude.Preferably, the contactor comprises a cover separating the interior space and the outside of the contactor. In an exemplary implementation of the invention, the cover has an inner face, and the lug has a substantially flat intermediate branch and disposed against the inner face of the cover, the connecting portion connecting to this intermediate portion, in particular via an elbow.
De préférence, la branche d'extrémité de la portion de connexion s'étend sensiblement perpendiculairement à la branche intermédiaire.Preferably, the end branch of the connecting portion extends substantially perpendicularly to the intermediate branch.
Le capot peut comporter, sur sa face intérieure, un picot sur lequel s'appuie latéralement la portion de connexion de la cosse.The cover may comprise, on its inner face, a pin on which bears laterally the connecting portion of the terminal.
Ce picot sert notamment de butée pour la portion de connexion de la cosse lorsqu'un effort de sertissage est exercé sur cette portion de connexion autour de la partie de fil à sertir.This pin serves in particular as a stop for the connection portion of the terminal when a crimping force is exerted on this connecting portion around the portion of wire to be crimped.
Ce picot peut également servir de relief de détrompage lors de la fixation du capot sur le reste du contacteur.This pin can also be used as keying relief when fixing the cover on the rest of the contactor.
Le picot comporte par exemple une face latérale sensiblement en portion de cylindre épousant sensiblement la forme de la portion de connexion de la cosse.The pin comprises for example a side face substantially in cylinder portion substantially conforming to the shape of the connecting portion of the terminal.
Dans un exemple de mise en oeuvre de l'invention, le contacteur comporte une pluralité de cosses, dont l'une au moins comporte une branche s'étendant à l'extérieur du contacteur, à travers le capot.In an exemplary implementation of the invention, the contactor comprises a plurality of terminals, at least one of which comprises a branch extending outside the contactor, through the cover.
La partie de cette branche dépassant à l'extérieur du capot définit un élément de contact électrique apte à coopérer avec un élément de connexion.The portion of this branch protruding outside the cover defines an electrical contact element capable of cooperating with a connection element.
Si on le souhaite, l'une des cosses s'étend entièrement dans l'espace intérieur du contacteur, étant notamment connectée à une borne de contact électrique du contacteur.If desired, one of the lugs extends entirely into the interior of the contactor, being in particular connected to an electrical contact terminal of the contactor.
Dans un exemple de mise en oeuvre de l'invention, cette cosse s'étendant entièrement dans l'espace intérieur du contacteur comporte une branche ajourée permettant de l'engager sur la borne de contactIn an exemplary implementation of the invention, this lug extending entirely in the interior of the contactor comprises a perforated branch for engaging it on the contact terminal
Cette borne est par exemple montée dans un orifice du capot.This terminal is for example mounted in a hole of the cover.
Avantageusement, le contacteur comporte un noyau fixe sensiblement en forme de disque, et comprenant au moins une encoche dans laquelle s'étend au moins partiellement la portion de connexion d'une cosse. Ce noyau fixe est réalisé par exemple en acier doux, et disposé contre une collerette d'un support du bobinage.Advantageously, the contactor comprises a substantially disk-shaped fixed core, and comprising at least one notch in which at least partially extends the connection portion of a terminal. This fixed core is made for example of mild steel, and arranged against a collar of a winding support.
Dans un exemple de mise en oeuvre de l'invention, l'un au moins du noyau et de la collerette peut comporter une ou plusieurs encoches pour le passage d'une partie de fil de l'un des bobinages d'excitation.In an exemplary implementation of the invention, at least one of the core and the flange may comprise one or more notches for the passage of a portion of wire of one of the excitation windings.
L'une au moins des cosses est réalisée par exemple en acier, notamment par découpe et pliage.At least one of the lugs is made for example of steel, in particular by cutting and folding.
Le cas échéant, l'une au moins des cosses est réalisée d'un seul tenant, de manière monolithique.Where appropriate, at least one of the pods is made in one piece, in a monolithic manner.
L'invention a encore pour objet un procédé pour connecter un fil du bobinage à une portion de connexion d'une cosse d'un contacteur tel défini ci-dessus, le procédé comportant l'étape suivante : déformer la portion de connexion de la cosse de manière à obtenir le serrage du fil dans cette portion de connexion de la cosse.The invention also relates to a method for connecting a winding wire to a connection portion of a terminal of a contactor as defined above, the method comprising the following step: deforming the connection portion of the terminal so as to obtain the tightening of the wire in this connecting portion of the terminal.
La déformation de la portion de connexion est réalisée par exemple en introduisant latéralement un outil de sertissage dans une encoche d'un noyau fixe, une fois le capot fixé sur le reste du contacteur.The deformation of the connection portion is achieved for example by laterally introducing a crimping tool in a notch of a fixed core, once the cover fixed on the rest of the contactor.
L'invention pourra être mieux comprise à la lecture de la description détaillée qui suivre, d'un exemple de mise en œuvre non limitatif de l'invention, et à l'examen du dessin annexé, sur lequel :The invention will be better understood on reading the detailed description which follows, of an example of non-limiting implementation of the invention, and on examining the appended drawing, in which:

Ce picot 50 comprend une paroi 51 en portion de cylindre épousant sensiblement la forme de la portion de connexion 45 de manière à servir de butée lors de la déformation de cette portion de connexion 45 pour réaliser le sertissage.This pin 50 comprises a wall 51 in cylinder portion substantially conforming to the shape of the connecting portion 45 so as to serve as a stop during the deformation of this connecting portion 45 to achieve the crimping.
Le capot 12 comprend un rebord périphérique 80 de forme cylindrique sur lequel est réalisée une encoche 81 pour recevoir une portion de la branche d'extrémité 47.The cover 12 comprises a peripheral rim 80 of cylindrical shape on which is made a notch 81 for receiving a portion of the end branch 47.
La branche d'extrémité 47 se raccorde à une branche intermédiaire sensiblement plane 53 de manière perpendiculaire en formant un coude 54.The end branch 47 is connected to a substantially flat intermediate branch 53 perpendicularly to form a bend 54.
La branche intermédiaire 53 est disposée contre la face intérieure 49 du capot 12 et passe à travers une fente 55 formée sur une nervure 56 de ce capot 12, comme illustré sur la figure 4 notamment. La branche intermédiaire 53 se raccorde à une branche verticale 57 de manière perpendiculaire en formant un coude 58.The intermediate branch 53 is disposed against the inner face 49 of the cover 12 and passes through a slot 55 formed on a rib 56 of the cover 12, as shown in Figure 4 in particular. The intermediate branch 53 is connected to a vertical branch 57 perpendicularly forming a bend 58.
Cette branche 57 définit à son extrémité libre l'élément de contact 41.This branch 57 defines at its free end the contact element 41.
La branche verticale 57 comporte une patte de maintien 59 apte à frotter contre une surface interne de la colonne 43, en déformant légèrement celle-ci, de manière à maintenir axialement la cosse 40 dans la colonne 43 contre un retrait vers l'intérieur du contacteur.The vertical leg 57 comprises a holding lug 59 adapted to rub against an inner surface of the column 43, by slightly deforming the latter, so as to axially hold the lug 40 in the column 43 against a withdrawal towards the inside of the contactor .
Le contacteur 1 comprend en outre une deuxième cosse 60 agencée pour permettre de relier l'extrémité de fil 29 à la borne de contact 10.The contactor 1 further comprises a second lug 60 arranged to allow the end of the wire 29 to be connected to the contact terminal 10.
Cette cosse 60 comporte une portion de connexion 61 repliée par déformation autour de l'extrémité de fil 29.This lug 60 has a connecting portion 61 folded by deformation around the wire end 29.
Cette portion de connexion 61 comprend, à l'instar de la portion de connexion 40 décrite plus haut, une branche d'extrémité 63 sensiblement plane et deux doigts déformables 64.This connection portion 61 comprises, like the connection portion 40 described above, a substantially flat end branch 63 and two deformable fingers 64.
Cette portion de connexion 61 est en appui latéralement contre un picot 65 du capot 12, comme illustré par exemple sur la figure 4.This connecting portion 61 bears laterally against a pin 65 of the cover 12, as illustrated for example in FIG. 4.
La branche d'extrémité 63 se raccorde à une première branche intermédiaire 66 sensiblement plane via un coude 67, laquelle branche 66 s'étend contre une portion horizontale de la face intérieure 49 du capot 12.The end branch 63 is connected to a first substantially flat intermediate branch 66 via a bend 67, which branch 66 extends against a horizontal portion of the inner face 49 of the cover 12.
Cette première branche intermédiaire 66 se raccorde à une deuxième branche intermédiaire 69 via un coude 70, laquelle branche 69 s'étend contre une portion verticale de la face intérieure 49 du capot 12.This first intermediate branch 66 is connected to a second intermediate branch 69 via a bend 70, which branch 69 extends against a vertical portion of the inner face 49 of the cover 12.
La deuxième branche intermédiaire 69 se raccorde via un coude 71 à une branche ajourée 72 permettant de fixer la cosse 60 à la borne 10 en engageant cette borne 10 à travers l'ajour de la branche 72, comme on peut le voir sur la figure 1.The second intermediate branch 69 is connected via a bend 71 to a perforated branch 72 for fixing the lug 60 to the terminal 10 by engaging this terminal 10 through the opening of the branch 72, as can be seen in Figure 1 .
Dans l'exemple décrit, les cosses 40 et 60 sont réalisées en acier, avec éventuellement un revêtement anti-corrosion, notamment par découpage et pliage. Chaque portion de connexion 45 et 61 comporte des extrémités chanfreinées 75 permettant une introduction plus aisée du ou des fils dans la portion de connexion correspondante.In the example described, the lugs 40 and 60 are made of steel, possibly with an anti-corrosion coating, in particular by cutting and folding. Each connecting portion 45 and 61 has chamfered ends 75 allowing easier introduction of the son or son in the corresponding connection portion.
Le capot 12 comprend, sur sa face intérieure 49, deux nervures 83 parallèles de part et d'autre des contacts fixes 5 et 6, comme on peut le voir sur la figure 4.The cover 12 comprises, on its inner face 49, two ribs 83 parallel on either side of the fixed contacts 5 and 6, as can be seen in FIG. 4.
Une nervure 84 supplémentaire est prévue entre l'une des nervures 83 et le rebord 80.An additional rib 84 is provided between one of the ribs 83 and the rim 80.
On ne sort pas du cadre de la présente invention lorsqu'un réseau de nervures différent est prévu sur la face intérieure 49 du capot 12.It is not beyond the scope of the present invention when a different network of ribs is provided on the inner face 49 of the cover 12.
Le capot 12 est réalisé de préférence d'un seul tenant, par exemple par moulage d'une matière plastique, thermodurcissable ou thermoplastique.The cover 12 is preferably made in one piece, for example by molding a plastic material, thermosetting or thermoplastic.
La déformation des portions de connexion 45 et 61 est réalisée à l'aide d'un outil de sertissage 77 introduit latéralement dans l'encoche 36 correspondante du noyau fixe 35, une fois le capot 12 fixé sur le reste du contacteur, comme on peut le voir sur la figure 8.The deformation of the connection portions 45 and 61 is achieved by means of a crimping tool 77 introduced laterally into the corresponding notch 36 of the fixed core 35, once the cover 12 has been fastened to the remainder of the contactor, as can be see it in figure 8.
L'outil de sertissage 77 comporte une face d'attaque 78 sensiblement arrondie pour s'appliquer contre la portion de connexion 45 ou 61 et déformer celle-ci.The crimping tool 77 has a substantially rounded leading face 78 for pressing against and deforming the connecting portion 45 or 61.
La face d'attaque 78 peut comporter par exemple deux portions 79 disposées de manière à former à leur jonction un sommet 80. Ceci permet de mieux déformer la portion de connexion 45 ou 61 dans une région centrale de celle-ci et donc assurer un meilleur maintien du ou des fils dans la portion de connexion correspondante.The leading face 78 may comprise, for example, two portions 79 arranged in such a way as to form at their junction a vertex 80. This makes it possible to better deform the connection portion 45 or 61 in a central region thereof and thus to ensure better maintaining the son or son in the corresponding connection portion.
En variante, les portions 79 sont dans l'alignement l'une de l'autre.Alternatively, the portions 79 are in alignment with each other.
Bien entendu, l'invention n'est pas limitée à l'exemple de mise en œuvre qui vient d'être décrit.Of course, the invention is not limited to the implementation example which has just been described.
Par exemple, la cosse 40 peut être remplacée, selon les besoins, par une cosse à fixer sur une borne, à l'instar de la cosse 60. For example, the lug 40 can be replaced, as required, by a lug to be fixed on a terminal, like the lug 60.
