Description
Domaine de 1'invention La presente invention concerne le mode de montageField of the invention The present invention relates to the method of assembly
d'un contact mobile sur une tige de commande, que comporte un contacteur electromagnetique pour un circuit de puissance, notamment pour un moteur electrique d'un demarreur de moteur A. combustion interne, en particulier de vehicule automobile. of a movable contact on a control rod, which comprises an electromagnetic contactor for a power circuit, in particular for an electric motor of an engine starter A. internal combustion, in particular of a motor vehicle.
La presente invention a egalement pour objet un contacteur electromagnetique, notamment pour un moteur electrique d'un demarreur de moteur a combustion interne, comportant un tel montage. The present invention also relates to an electromagnetic contactor, in particular for an electric motor of an internal combustion engine starter, comprising such an assembly.
Etat de la technique Selon une conception connue un contacteur electromagnetique pour un circuit de puissance comporte un equipage mobile comprenant un contact mobile monte sur une tige de commande. Le contact mobile est destine a venir en contact avec des bornes electriques de contact fixes, agencees dans une chambre de contact A. 1'avant du contacteur. Ce contacteur est par exemple utilise pour commander 1'actionnement d'un moteur electrique d'un demarreur de moteur a combustion interne. La figure 1, qui est une vue partielle en coupe axiale, illustre un tel contacteur 10 de 1'etat de la technique pour un moteur electrique d'un demarreur de moteur A. combustion interne, dote d'un noyau mobile 16, d'un noyau fixe 24, tous deux en materiau ferromagnetique, et d'un carter metallique 12, appele egalement cuve, dans lequel est agencee au moins une bobine 14 montee sur un support annulaire isolant (non reference). Le support est engage sur une portee annulaire (non referencee) du noyau fixe 24. Ce support et 1' extremite arriere de la cuve 12 sont dotes centralement d'un passage pour le noyau mobile 16. Cette bobine 14, lorsqu'elle est activee electriquement suite par exemple a 1'actionnement de la de de contact, commande le deplacement axial du noyau mobile 16 en direction du noyau fixe 24. Une extremite du noyau mobile 16 est reliee a un levier pivotant (non represents) qui agit par exemple sur le lanceur du demarreur comme decrit dans le document FR A 2 795 884 et c'est pour cette raison que Pon voit partiellement en 50 dans la figure 1 le ressort dents contre dents et en 51 la tige de liaison au levier pivotant. L'autre extremite avant 18 du noyau mobile 16 est destinee a agir sur une tige de commande 20 par poussee a travers un trou 22 central du noyau fixe 24 dans lequel la partie arriere 26 de la tige 20 est montee coulissante. La tige 51 et le ressort 50 sont montes a 1'interieur d'une cavite fermee par 1'extremite avant 18, en forme de rondelle, du noyau mobile 16, qui commande les deplacements axiaux de la tige de commande 20, en matiere electriquement isolante Cette tige est donc poussee par son extremite arriere 26 et elle porte a son extremite opposee avant 28 un contact mobile 30, monte coulissant sur la tige de commande 20. Le contact mobile 30 est sensiblement en forme de plaque en materiau electriquement conducteur. STATE OF THE ART According to a known design, an electromagnetic contactor for a power circuit comprises a mobile crew comprising a movable contact mounted on a control rod. The movable contact is intended to come into contact with fixed electrical contact terminals, arranged in a contact chamber A. the front of the contactor. This contactor is for example used to control the operation of an electric motor of an internal combustion engine starter. FIG. 1, which is a partial view in axial section, illustrates such a contactor 10 of the state of the art for an electric motor of an internal combustion engine starter A., equipped with a mobile core 16, with a fixed core 24, both of ferromagnetic material, and a metal housing 12, also called tank, wherein is arranged at least one coil 14 mounted on an annular insulating support (not reference). The support is engaged on an annular door (not referencee) of the fixed core 24. This support and 1 'rear end of the tank 12 are provided centrally with a passage for the movable core 16. This coil 14, when activated For example, electrically following the actuation of the contact element controls the axial displacement of the movable core 16 towards the fixed core 24. An end of the mobile core 16 is connected to a pivoting lever (not shown) which acts for example on the launcher of the starter as described in the document FR A 2,795,884 and it is for this reason that Pon partially sees in 50 in Figure 1 the spring teeth against teeth and in 51 the connecting rod to the pivoting lever. The other end before 18 of the movable core 16 is intended to act on a control rod 20 by pushing through a central hole 22 of the fixed core 24 in which the rear portion 26 of the rod 20 is slidably mounted. The rod 51 and the spring 50 are mounted inside a cavity closed by the forward end 18, in the form of a washer, of the movable core 16, which controls the axial displacements of the control rod 20, electrically This rod is thus pushed by its rear end 26 and carries at its opposite end before 28 a movable contact 30, slidably mounted on the control rod 20. The movable contact 30 is substantially plate-shaped electrically conductive material.
Ce contact 30 s'etend transversalement pour cooperer avec deux tetes 32 et 34 de bornes electriques 36 et 38 d'un circuit electrique de puissance et etablir entre elles un contact electrique par sa face avant 29. Les deux bornes 36 et 38 sont fixes et sont portees par un capot avant 40 en materiau electriquement isolant, qui est fixe par sertissage dans une partie avant du carter 12. Le capot 40 delimite une chambre de contact pour les tetes 32, 34 et pour le contact mobile 30. Ce capot 24 sert egalement a la fixation du noyau fixe 24, cale axialement entre un epaulement du capot 20 et le noyau fixe 24 dote de saillies axiales s'engageant dans des echancrures du noyau fixe 24 pour blocage en rotation et indexation angulaire du capot 40. Une des bornes 36, 38 est destinee a titre reliee a la borne positive de la batterie, tandis que 1autre borne est destinee a titre reliee au moteur electrique du demarreur comme decrit par exemple dans le document FR A 2 795 884 precite. This contact 30 extends transversely to cooperate with two heads 32 and 34 of electrical terminals 36 and 38 of an electrical power circuit and establish between them an electrical contact by its front face 29. The two terminals 36 and 38 are fixed and are carried by a front cover 40 of electrically insulating material, which is fixed by crimping in a front portion of the housing 12. The cover 40 delimits a contact chamber for the heads 32, 34 and the movable contact 30. This cover 24 serves also to the fixing of the fixed core 24, wedge axially between a shoulder of the cover 20 and the fixed core 24 has axial projections engaging in notches of the fixed core 24 for blocking rotation and angular indexing of the cover 40. One of the terminals 36, 38 is intended for the purpose of connection to the positive terminal of the battery, while another terminal is intended for the purpose of connecting to the electric motor of the starter as described for example in the document FR A 2,795,884 above.
La tige 20 porte un ressort axial de maintien 42 agence entre un epaulement axial arriere 44 de la tige 20 et une face arriere 31 du contact mobile 30. Le ressort 42 est prevu pour maintenir le contact mobile 30 en appui vers 1'avant sur des moyens de butee axiale avant 46 lorsque le contact mobile 30 n'est pas en contact avec les tetes 32, 32. Ces moyens 46 sont constitues par une rondelle de butee immobilisee axialement par une rondelle a griffes, qui est elastique et consiste en une rondelle Belleville presentant a sa peripherie interne des pattes adaptees a s'ancrer dans la partie avant de la tige 20. Enfin le contacteur 10 comporte un ressort de rappel 48 agence entre le capot avant 40 et la tige de commande 20 pour rappeler cette derniere, et par consequent le contact mobile 30, en arriere. Ce ressort 48 prend appui sur la rondelle a griffes et sur le capot 40. Le ressort de rappel 48, appele egalement ressort de coupure, a une raideur inferieure au ressort de maintien 42, appele egalement ressort de pression de contact, permettant lors d'une derniere phase au noyau mobile 16 de venir au contact du noyau fixe 24 et a la tige 20 de se deplacer apres venue en contact du contact mobile 30 avec les tetes 32, 34. Lors de cette derniere phase le ressort 42 est comprime et le contact mobile 30 occupe en final une position active reculee. Ainsi, lors de la mise sous tension, la bobine 14 cree un champs magnetique, qui permet 1'entrainement axialement vers 1'avant du noyau mobile 16, qui deplace alors la tige de commande 20 et le contact mobile 30, ce dernier etant amene au contact des tetes 32, 34 pour operer un contact electrique entre les bornes 36,38 et alimenter electriquement le moteur electrique du demarreur. The rod 20 carries an axial retaining spring 42 arranged between an axial rear shoulder 44 of the rod 20 and a rear face 31 of the movable contact 30. The spring 42 is provided to keep the movable contact 30 bearing forward on front axial abutment means 46 when the movable contact 30 is not in contact with the heads 32, 32. These means 46 are constituted by a stop washer immobilized axially by a claw washer, which is elastic and consists of a washer Belleville having at its inner periphery lugs adapted to anchor in the front portion of the rod 20. Finally the switch 10 comprises a return spring 48 arranged between the front cover 40 and the control rod 20 to recall the latter, and therefore the movable contact 30, back. This spring 48 is supported on the claw washer and on the cover 40. The return spring 48, also called the cutoff spring, has a stiffness lower than the holding spring 42, also called contact pressure spring, allowing for a last phase with the movable core 16 coming into contact with the fixed core 24 and with the rod 20 to move after coming into contact with the movable contact 30 with the heads 32, 34. During this last phase the spring 42 is compressed and the movable contact 30 occupies finally a retracted active position. Thus, when energized, the coil 14 creates a magnetic field, which allows the axially forward drive of the movable core 16, which then displaces the control rod 20 and the movable contact 30, the latter being brought in contact with the heads 32, 34 for making an electrical contact between the terminals 36, 38 and electrically supplying the electric motor of the starter.
Lors de la mise hors tension de la bobine 14, le noyau mobile 16 n'est plus entraine vers 1'avant et le ressort de rappel 48 repousse la tige de commande 20 vers 1'arriere jusqu'a ce que le contact mobile 30 soit en butee sur le noyau fixe 24. Le contact mobile 30 est donc monte coulissant sur la tige 20 entre une position avancee de repos et une position reculee active. Le ressort 42 sollicite axialement le contact mobile 30 vers sa position de repos dans laquelle it est en contact avec les moyens de butee avant 46. Dans sa position active le contact mobile est en contact avec les tetes 32, 34 et le ressort 42 est comprime en sorte qu'un jeu existe entre le contact 30 et les moyens de butee 46 (figure 1). L'agencement du contact 30 sur la tige 20 est assez complexe et comporte un certain nombre de pieces quill faut assembler. Cet agencement comporte dans la figure 1 six pieces a savoir la tige de commande 20 A. epaulement axial arriere 44, le ressort de maintien 42, le contact mobile 30, les moyens de bute butee 46 comportant la rondelle de butee et la rondelle a griffes et enfin le ressort de rappel 48. When the coil 14 is de-energized, the movable core 16 is no longer driven forward and the return spring 48 pushes the control rod 20 rearward until the movable contact 30 is The movable contact 30 is thus slidably mounted on the rod 20 between an advanced rest position and an active retracted position. The spring 42 axially urges the movable contact 30 towards its rest position in which it is in contact with the front stop means 46. In its active position, the movable contact is in contact with the heads 32, 34 and the spring 42 is compressed. so that a clearance exists between the contact 30 and the stop means 46 (Figure 1). The arrangement of the contact 30 on the rod 20 is quite complex and comprises a number of pieces that must be assembled. This arrangement comprises in FIG. 1 six parts, namely the control rod 20 A. rear axial shoulder 44, the retaining spring 42, the movable contact 30, the abutment abutment means 46 comprising the abutment washer and the claw washer and finally the return spring 48.
Ces operations d'assemblage ne sont pas aussi pratique que souhaite et demandent une certaine minutie. De plus, les moyens de fixation des moyens de butee 46 sur la tige 20 ont pour inconvenient de creer des particules de matiere isolante qui resultent du montage a force de la rondelle de fixation a griffes. Ces particules isolantes risquent de nuire au contact entre les tetes 32, 34 et le contact mobile si elles se placent entre ces elements. Une autre solution decrite par exemple dans le document FR A 2 741 996 consiste a realiser des rainures dans la tige de commande et a deformer radialement par sertissage le contact mobile pour former des ergots, qui sont recus en coulissement dans les rainures delimitees a 1'avant par une surface de butee pour le contact mobile. Une telle solution donne satisfaction car elle permet de reduire le nombre de pieces neanmoins lors du sertissage des fissures peuvent 15 apparaitre. Objet de 1'invention These assembly operations are not as convenient as desired and require some minutiae. In addition, the fastening means of the abutment means 46 on the rod 20 have the disadvantage of creating insulating material particles that result from the forced assembly of the claw fastener washer. These insulating particles may affect the contact between the heads 32, 34 and the movable contact if they are placed between these elements. Another solution described, for example, in document FR A 2,741,996 consists in producing grooves in the control rod and radially deforming the mobile contact by crimping to form lugs, which are slidably receivable in the grooves delimited at one end. before by a stop surface for the moving contact. Such a solution is satisfactory because it reduces the number of parts nevertheless crimping cracks can appear. Object of the invention
20 Pour remedier a ces inconvenients, tout en ayant un nombre de pieces reduit, la presente invention propose de creer un assemblage du type baionnette pour monter le contact mobile sur la tige de commande. To overcome these drawbacks, while having a reduced number of parts, the present invention proposes to create a bayonet type assembly to mount the movable contact on the control rod.
Suivant l'invention un equipage mobile pour contacteur 25 electromagnetique de puissance du type comportant un contact mobile porte par une tige de commande est caracterise en ce que des moyens d'assemblage du type baionnette interviennent entre le contact mobile et la tige de commande pour montage du contact mobile sur la tige de commande. 30 Suivant l'invention un contacteur electromagnetique, notamment pour un moteur electrique d'un demarreur de moteur a combustion interne, du type sus-indique comportant un equipage mobile est caracterise en ce que son equipage mobile est dote de moyens d'assemblage du type balonnette, qui interviennent entre le contact 35 mobile et la tige de commande pour montage du contact mobile sur la tige de commande. According to the invention, a mobile unit for an electromagnetic power contactor of the type comprising a movable contact carried by a control rod is characterized in that bay assembly means intervene between the movable contact and the control rod for mounting. mobile contact on the control rod. According to the invention, an electromagnetic contactor, particularly for an electric motor of an internal combustion engine starter, of the aforementioned type comprising a mobile crew is characterized in that its mobile crew is provided with assembly means of the type balonnette, which intervene between the movable contact and the control rod for mounting the movable contact on the control rod.
Ainsi le contact mobile, par 1'intermediaire de son trou ou orifice central, formant un passage, est mis en place sur la tige de commande puis est tourne pour venir en contact par sa face avant avec au moins une butee solidaire de la tige de commande. Thus the movable contact, through its hole or central orifice, forming a passage, is placed on the control rod and is rotated to come into contact with its front face with at least one stop integral with the rod. ordered.
Grace a l'invention par rapport a la solution de la figure 1 on supprime deux pieces a savoir la rondelle de butee et la rondelle a griffes en sorte que la solution est simple, economique et permet de reduire le nombre de pieces A. stocker. Thanks to the invention compared to the solution of Figure 1 is removed two pieces namely the abutment washer and the claw washer so that the solution is simple, economical and reduces the number of pieces A. Store.
En outre le montage est plus rapide et sans risque, d'une part, de pollution de la chambre de contact par des particules arrachees sur la tige de commande lors du montage de la rondelle a griffes du fait de la suppression de cette rondelle a griffes, et d'autre part, d'oubli de montage de la rondelle de butee et/ou de la rondelle a griffes. In addition, the assembly is faster and without risk, on the one hand, pollution of the contact chamber by particles torn off the control rod during assembly of the claw washer due to the removal of this washer has claws and on the other hand, forgetting the mounting of the stop washer and / or the claw washer.
On ameliore egalement la fiabilite du contacteur par suppression de la rondelle elastique a griffes sollicitee en fatigue tors du fonctionnement du contacteur. It also improves the reliability of the contactor by removing the resilient washer with claws strained in torsional stress of the operation of the contactor.
Par rapport a la solution a sertissage decrite dans le document FR A 2 741 996 on ameliore egalement la fiabilite du contacteur du fait de 1'absence de sertissage au niveau du contact mobile faisant apparaitre dans certains cas des amorces de rupture et/ ou des fissures. Compared to the crimping solution described in document FR A 2,741,996, the reliability of the contactor is also improved because of the absence of crimping at the level of the moving contact, which in some cases appears to reveal failure primers and / or cracks. .
II en resulte que la solution selon l'invention permet d'augmenter la duree de vie du contacteur. On peut donc arreter et redemarrer le monteur a combustion interne un plus grand nombre de fois. Ainsi dans le cas d'une application a un vehicule automobile on 30 peut arreter le moteur A. combustion interne au feu rouge et le redemarrer pour reduire la consommation de carburant. As a result, the solution according to the invention makes it possible to increase the life of the contactor. It is therefore possible to stop and restart the internal combustion fitter a greater number of times. Thus, in the case of application to a motor vehicle, the internal combustion engine A. can be stopped at a red light and restarted to reduce fuel consumption.
De plus dans tous les cas on peut monter aisement, voir manuellement, le contact mobile sur la tige de commande. 35 Le montage du contact mobile sur sa tige de commande est realise sans precautions particulieres, est robuste et tire partie du ressort de maintien qui sollicite le contact mobile en direction d'au moins une butee rigide solidaire de la tige de commande. De preference, pour une meilleure fiabilite, la butee est d'un seul tenant avec la tige de commande. Suivant une caracteristique les moyens d'assemblage du type 5 balonnette sont configures pour realiser un blocage en rotation du contact mobile par rapport A. la tige de commande. Ainsi le montage est fiable dans le temps. Moreover, in all cases, the movable contact on the control rod can be easily mounted, see manually. The assembly of the movable contact on its control rod is carried out without particular precautions, is robust and takes advantage of the holding spring which urges the moving contact towards at least one rigid stop secured to the control rod. Preferably, for better reliability, the stop is in one piece with the control rod. According to a characteristic, the balancette-type assembly means are configured to realize a locking in rotation of the movable contact with respect to the control rod. Thus the assembly is reliable in time.

Description of Exemplary Embodiments of the Invention
Sur les figures, des elements identiques, similaires ou 35 analogues sont designes par les memes chiffres de reference. 30 Dans la figure 2 on voit en 100 1'equipage mobile selon l'invention et en 48 le ressort de rappel associe a cet equipage, cet ensemble 100-48 se montant en lieu et place de celui de la figure 1. Plus precisement dans les figures 2 a 12 on n'a represente que la tige de commande 20 le ressort de maintien 42, le contact mobile 30 et le ressort de rappel 48 du contacteur electromagnetique, ces quatre pieces, mieux visibles dans la figure 3, se montant en lieu et place des six pieces 20, 42, 30, 46 et 48 de la figure 1 en sorte que 1'invention permet de reduire le nombre de pieces. In the figures, identical, similar or similar elements are designated by the same reference numerals. In FIG. 2, the moving crew according to the invention is shown at 100 and in the return spring associated with this crew, this assembly 100-48 being mounted in place of that of FIG. 1. More precisely in FIG. FIGS. 2 to 12 show only the control rod 20, the retaining spring 42, the movable contact 30 and the return spring 48 of the electromagnetic contactor, these four parts, which can be seen more clearly in FIG. instead of the six pieces 20, 42, 30, 46 and 48 of Figure 1 so that 1'invention reduces the number of pieces.
Les ressorts 48 et 42 sont des ressorts helicofdaux de forme cylindrique comme a la figure 1. Le diametre externe du ressort 42 est ici superieur au diametre externe du ressort 48. Le ressort 42 est plus raide que le ressort 48. La tige 20 de commande, le ressort de maintien 42 et le contact mobile 30, porte par la tige 20, appartiennent a 1'equipage mobile 100. Par rapport a la figure 1 on modifie de maniere decrite ci-apres une partie de la tige de commande 20 et le trou ou orifice central 246 du contact mobile 30 sous la forme d'une plaquette globalement de forme rectangulaire comme a la figure 1. The springs 48 and 42 are cylindrical helicofdales springs as in Figure 1. The outer diameter of the spring 42 is here greater than the outer diameter of the spring 48. The spring 42 is stiffer than the spring 48. The rod 20 control , the retaining spring 42 and the movable contact 30, carried by the rod 20, belong to the mobile crew 100. Compared with FIG. 1, a part of the control rod 20 is modified in the manner described below and the hole or central orifice 246 of the movable contact 30 in the form of a wafer generally of rectangular shape as in FIG.
La tige 20 est en materiau electriquement isolant, tandis que le contact mobile 30, porte par la tige 20, est en materiau electriquement conducteur. Le contact mobile 30 est dans ce mode de realisation metallique par exemple en cuivre, et est adapte a cooperer par sa face avant 29 avec les tetes 32 et 36 des bornes 36 et 38 de la figure 1 et par sa face arriere 31 avec 1'extremite avant du noyau fixe du contacteur electromagnetique de la figure 1. Le ressort de maintien 42 est en appui sur 1'epaulement arriere 44 de la tige 20 et sur la face arriere 31 du contact mobile 30 d'orientation transversale par rapport a 1'axe de symetrie axial X-X (Figure 6) que presente la tige 20. Ce contact 30 est obtenu ici par decoupage a la presse. La tige 20 est ici en matiere plastique isolante renforcee eventuellement par des fibres. Elie est par exemple en PA 6-6 et est obtenu par moulage permettant 1'obtention des formes souhaitees. The rod 20 is made of electrically insulating material, while the movable contact 30, carried by the rod 20, is electrically conductive material. The mobile contact 30 is in this embodiment of metal for example copper, and is adapted to cooperate by its front face 29 with the heads 32 and 36 of the terminals 36 and 38 of Figure 1 and its rear face 31 with 1 ' front end of the fixed core of the electromagnetic contactor of FIG. 1. The retaining spring 42 bears on the rear shoulder 44 of the rod 20 and on the rear face 31 of the movable contact 30 of transverse orientation relative to 1 '. axial axis of symmetry XX (Figure 6) that the rod 20. This contact 30 is obtained here by cutting the press. The rod 20 is here made of insulating plastic possibly reinforced by fibers. Elie is for example PA 6-6 and is obtained by molding to obtain the desired shapes.
En variante la tige 20 est en ceramique et est obtenue par exemple par frittage. Alternatively the rod 20 is ceramic and is obtained for example by sintering.
La tige 20 presente une extremite arriere 26, une extremite avant 28 et, entre ces extremites 26, 28, une partie arriere de guidage 133, 134, 1'epaulement arriere 44, une partie centrale 129, 130, 131 et une partie avant 128 de montage du ressort de rappel 48. The rod 20 has a rear end 26, a front end 28 and, between these ends 26, 28, a rear guide portion 133, 134, the rear shoulder 44, a central portion 129, 130, 131 and a front portion 128 for mounting the return spring 48.
L'extremite arriere 26, ici en forme de chanfrein pour faciliter le montage de la tige dans le trou central du noyau fixe de la figure 1, est destinee a etre sollicitee au niveau de sa face arriere par la rondelle avant 18 du noyau mobile de la figure 1 pour deplacement axial de la tige 20. Le chanfrein 26 (figure 6) se raccorde a 1'avant a un troncon 134 de forme cylindrique prolonge lui-meme vers 1'avant par un troncon 133 de forme cylindrique de diametre legerement superieur a celui du troncon 134. En pratique l'usinage du troncon 133 est realise avec des tolerances plus precises car ce troncon 133 est destine a cooperer de maniere intime avec la peripherie interne du noyau fixe delimitant le trou 22 de la figure 1. Dans le mode de realisation de la figure 1 on peut adopter cet agencement qui permet de reduire les coats. Les troncons 134, 133 constituent la partie arriere de guidage de la tige, qui en variante ne comporte que le troncon 133. The rear end 26, here chamfered to facilitate mounting of the rod in the central hole of the fixed core of Figure 1, is intended to be urged at its rear face by the front washer 18 of the movable core. Figure 1 for axial displacement of the rod 20. The chamfer 26 (Figure 6) is connected at the front to a trunk 134 of cylindrical shape itself extends forwardly by a troncon 133 of cylindrical shape of slightly greater diameter to that of the trunk 134. In practice the machining of the troncon 133 is made with more precise tolerances because this troncon 133 is intended to cooperate intimately with the inner periphery of the fixed core delimiting the hole 22 of Figure 1. In the embodiment of Figure 1 we can adopt this arrangement that reduces costs. The troncons 134, 133 constitute the rear part of the guide of the rod, which as a variant comprises only the trunk 133.
L'epaulement 44 est delimite par une face avant 144 et par une face arriere 132. Plus precisement le troncon 133 se raccorde a 1'avant a 1'epaulement arriere 44 de la tige 20, plus precisement a la face arriere 132 de 1'epaulement 44. Cette face arriere 132 est evasee en etant ici de forme tronconique, adaptee a la forme du passage central du noyau fixe de la figure 1. Cet epaulement. 44 s'etend en saillie radiale par rapport a la partie arriere 133, 134 et constitue, par 1'intermediaire de sa face avant 144, d'orientation transversale par rapport a 1'axe central X-X de la tige, une butee arriere pour le ressort de maintien 42. The shoulder 44 is delimited by a front face 144 and by a rear face 132. More precisely the trunk 133 is connected to the front at the rear shoulder 44 of the rod 20, more precisely to the rear face 132 of 1 '. shoulder 44. This rear face 132 is tapered here being of frustoconical shape, adapted to the shape of the central passage of the fixed core of Figure 1. This shoulder. 44 projects radially relative to the rear portion 133, 134 and constitutes, through its front face 144, transverse orientation relative to the central axis XX of the rod, a rear stop for the holding spring 42.
Ici 1'epaulement 44 est en forme de collerette annulaire dont le diametre externe est superieur a celui de la partie arriere 133, 134 et a un quatrieme tronwon cylindrique 142 de montage de 1'extremite arriere du ressort de maintien 42 enfilee sur ce troncon 142 appartenant A. la partie centrale de la tige 20. Le tronwon 142 est delimite par la face avant 144. Here the shoulder 44 is in the form of an annular collar whose outer diameter is greater than that of the rear portion 133, 134 and has a fourth cylindrical section 142 for mounting the rear end of the holding spring 42 threaded on this trunk 142 belonging to A. the central part of the rod 20. The section 142 is delimited by the front face 144.
L'extremite avant 28 est ici de forme tronconique, en variante de forme arrondie ou en forme d'ogive, pour faciliter le montage du ressort de rappel 48. Cette extremite se raccorde a un premier troncon 128 de forme cylindrique constituant la partie avant de la tige 20. L'extremite arriere du ressort de rappel 48 se monte, ici a jeu de montage, par enfilage sur ce troncon 128. La partie centrale de la tige 20 s'etend entre la face avant de 1'epaulement 44 et le premier troncon 128 de montage du ressort 48. Cette partie centrale comporte d'avant en arriere, dans le sens allant de gauche a droite dans la figure 6, un deuxieme troncon 129, un troisieme troncon 130, un chanfrein de raccordement 131 et un quatrieme troncon a savoir le troncon 142 de montage du ressort de maintien 42. The front end 28 is of frustoconical shape, alternatively rounded or ogival-shaped, to facilitate the mounting of the return spring 48. This end is connected to a first trunk 128 of cylindrical shape constituting the front part of 20. The rear end of the return spring 48 is mounted, here a set of mounting, by threading on this trunk 128. The central portion of the rod 20 extends between the front face of 1'auaement 44 and the first central portion 128 for mounting the spring 48. This central portion comprises, from the front to the rear, in the direction from left to right in FIG. 6, a second section 129, a third section 130, a connecting chamfer 131 and a fourth section. troncon namely the trunk 142 for mounting the retaining spring 42.
Selon l'invention le contact mobile 30 est monte sur sa tige de commande 20 par 1'intermediaire de moyens d'assemblage du type baYonnette. Dans les figures 2 a 12 c'est, d'une part, le deuxieme troncon 129 et le troisieme troncon 130 de la partie centrale de la tige 20 et d'autre part, le trou ou orifice central 246 du contact mobile 30, qui sont configures pour appartenir aux moyens d'assemblage du type balonnette. Ici par rapport a la figure 1 on diminue la longueur axiale du troncon de montage 142 du ressort de maintien 42, ainsi que la longueur axiale du premier troncon 128 de montage du ressort de rappel 48 pour conserver la longueur axiale de la tige 20. La diminution de longueur axiale du premier troncon 128 est rendue possible grace a la suppression de la rondelle a griffes et de la rondelle de butee de la figure 1. Ce premier troncon 128 est donc menage par rapport a celui de la figure 1 car it est moins sollicite mecaniquement. Le troisieme troncon 130 est de forme cylindrique et presente un diametre externe inferieur a celui du quatrieme troncon 142, le chanfrein 131 etant un chanfrein de raccordement entre les troncons 130 et 142. According to the invention the movable contact 30 is mounted on its control rod 20 by means of bayonet type assembly means. In FIGS. 2 to 12 it is, on the one hand, the second section 129 and the third section 130 of the central part of the rod 20 and, on the other hand, the central hole or orifice 246 of the movable contact 30, which are configures to belong to the assembly means of the balonnette type. Here, with respect to FIG. 1, the axial length of the mounting section 142 of the holding spring 42 is reduced, as is the axial length of the first section 128 for mounting the return spring 48 to maintain the axial length of the rod 20. axial length reduction of the first section 128 is made possible by the removal of the claw washer and the abutment washer of Figure 1. This first section 128 is household compared to that of Figure 1 because it is less mechanically solicits. The third trunk 130 is cylindrical in shape and has an external diameter less than that of the fourth trunk 142, the chamfer 131 being a connecting chamfer between the trunks 130 and 142.
Dans ce mode de realisation le quatrieme troncon 142 et le troisieme troncon 130 ont un diametre externe superieur a celui des troncons 133, 134. Bien entendu cela depend des applications. Le premier troncon 128 et le troisieme troncon 130 ont dans ce mode de realisation le meme diametre externe. In this embodiment, the fourth trunk 142 and the third trunk 130 have an outer diameter greater than that of the trunks 133, 134. Of course this depends on the applications. The first trunk 128 and the third trunk 130 have in this embodiment the same outer diameter.
Le troisieme troncon 130 est un troncon dit troncon de rotation permettant une rotation du contact mobile 30, tandis que le deuxieme troncon 129 et un troncon dit troncon de passage et de blocage du contact mobile 30. Ce deuxieme troncon 129 autorise egalement le passage du ressort 42. Dans cet exemple de realisation le deuxieme troncon 129 comporte une portion arriere 124, 123 (figure 7) de section earl-6e a coins arrondis. Cette portion arriere presente un diametre D au niveau de ces coins et une largeur D1 entre ces coins. Le deuxieme troncon 129 presente une portion avant 127, 123 (figure 8) avec deux meplats 123 paralleles separes Pun de 1'autre par une distance D1 egale a celle des cotes Dl du carre de sa portion arriere. The third troncon 130 is a so-called truncon section of rotation allowing a rotation of the movable contact 30, while the second section 129 and a truncon said trunk passage and blocking the movable contact 30. This second section 129 also allows the passage of the spring 42. In this embodiment, the second section 129 comprises a rear portion 124, 123 (Figure 7) Earl-6e section with rounded corners. This rear portion has a diameter D at these corners and a width D1 between these corners. The second section 129 has a front portion 127, 123 (Figure 8) with two parallel flat 123 parallel to each other by a distance D1 equal to that of the dimensions Dl of the square of its rear portion.
Ces deux meplats 123 sont raccordes entre eux par deux portions cylindriques 127 de diametre D egal a celui sur lequel sont situes les coins arrondis de sa portion arriere. Le diametre D est egal, au jeu de montage pres, a celui du diametre interne de celui du ressort 42 et a celui du quatrieme troncon 142. Ainsi le ressort 42 se monte simplement par enfilage axial d'avant en arriere sur la tige 20 jusqu'a sa venue en butee contre la face avant 144 de 1'epaulement arriere 44, qui presente le plus grand diametre externe de la tige 20. L'ouverture ou orifice central 246 du contact mobile 30 a une forme complementaire a celle de la portion avant 123, 127 du deuxieme troncon 129. Cette ouverture 246 (Figure 5) est donc delimitee par deux meplats paralleles separes Pun de 1'autre par une distance D' l egale au jeu de montage pres a la largeur Dl du cane de la portion arriere du troncon 129. Ces deux meplats sont raccordes entre eux par deux portions cylindriques diametralement opposees de diametre D' egal au jeu de montage pres a celui D sur lequel sont situes les coins arrondis de la portion avant du troncon 129. I1 ressort de la description et des dessins que le deuxieme troncon 129 comporte deux premieres faces paralleles 123 separees 1'une de 1'autre par la distance D1. Ces deux premieres faces s'etendent entre les deux troncons cylindriques 128 et 130 de diametre externe egale a cette distance D1. Ces deux premieres faces 123 s'etendent donc de maniere continue axialement le long du deuxieme troncon 129 et constituent les deux meplats de la portion avant 123, 127 et deux des cotes de la portion arriere 123, 124 du deuxieme troncon 129. Ce deuxieme troncon 129 comporte egalement deux deuxiemes faces paralleles 124 separees 1'une de 1'autre par la distance Dl. Ces deuxiemes faces 124 sont perpendiculaires aux premieres faces 123 et constituent les deux autres cotes de la portion arriere 123, 124 du deuxieme troncon. Les deux faces 124 s'etendent vers 1'avant a partir du troisieme 5 troncon 130 de diametre externe D1 inscrit dans le carre a coins arrondi de diametre D comme mieux visible a la figure 6. Les deuxiemes faces 124 s'etendent axialement chacune jusqu'a la face arriere 125 d'une but&e 127. Chaque butee 127, saillante radialement et formant un relief, est en forme de portion cylindrique de 10 diametre externe D &gal, au jeu de tolerances pres, a celui du quatrieme troncon 142 et a celui des portions cylindriques complementaires de l'orifice 246 du contact mobile 30. Les butees 127 constituent les portions cylindriques de la portion avant 123, 127 du deuxieme troncon. Ces butees sont rigides. 15 La face avant 126 de chaque butee 127 saillante sert de butee a la face arriere du ressort 48 prenant appui par sa face avant sur le fond du capot 40 de la figure 1. Les deux butees rigides 127 remplacent les moyens de butee avant 46 de la figure 1 et sont donc des butees avant ici rigides. 20 Ces deux butees 127, consistant en des portions cylindriques de diametre externe D, sont diametralement opposees et sont donc entaillees par les faces 124 et c'est la raison pour laquelle on voit a la figure 6 la presence de bras non references. Ces bras delimitent lateralement chaque deuxieme face 124 ainsi que les coins arrondis de la portion arriere du 25 deuxieme troncon 129. Ces bras presentent une peripherie externe implantee sur une circonference de diametre D &gal a celui du quatrieme troncon 142. Ainsi qu'il ressort de ce qui precede le deuxieme troncon est un troncon de passage autorisant par ses premieres faces 123 et ses portions 30 cylindriques 127 le passage axial de l'ouverture 246 du contact mobile 30. Ce contact 30 est ainsi enfile axialement sur le deuxieme troncon (figure 10) a 1'encontre de la force exercee par le ressort 42 pour parvenir jusqu'au troisieme troncon 130 (figure 11), le ressort 42 etant enfile par avance sur la tige 20. 35 Lors de cette premiere &tape les faces paralleles du contact mobile 30, constituees par les deux meplats de l'ouverture 246 du contact mobile, sont enfilees axialement a jeu de montage sur les premiere faces 123 du troncon 129 et le ressort 42 est comprim& axialement, ce ressort prenant appui sur la face avant 144 de 1'&paulement 44 et sur la face arriere 31 du contact mobile faisant office de plateau de pression et 1'&paulement 44 de plateau de reaction. These two flat surfaces 123 are connected to each other by two cylindrical portions 127 of diameter D equal to that on which are located the rounded corners of its rear portion. The diameter D is equal to the mounting clearance close to that of the inner diameter of that of the spring 42 and that of the fourth trunk 142. Thus the spring 42 is simply mounted by axial threading back and forth on the rod 20 until its abutment against the front face 144 of the rear shoulder 44, which has the largest outer diameter of the rod 20. The opening or central orifice 246 of the movable contact 30 has a shape complementary to that of the portion before 123, 127 of the second section 129. This opening 246 (Figure 5) is therefore delimited by two parallel plates separated from the other by a distance D 'equal to the mounting clearance near the width Dl of the cane of the portion 129. These two plates are interconnected by two diametrically opposite cylindrical portions of diametre D equal to the mounting clearance close to that D on which are located the rounded corners of the front portion of the trunk 129. It emerges from the description and drawings that e the second section 129 comprises two first parallel faces 123 separated from each other by the distance D1. These first two faces extend between the two cylindrical trunks 128 and 130 of outer diameter equal to this distance D1. These first two faces 123 therefore extend continuously axially along the second section 129 and constitute the two flat portions of the front portion 123, 127 and two of the sides of the rear portion 123, 124 of the second section 129. This second trunk 129 also has two second parallel faces 124 separated from each other by the distance Dl. These second faces 124 are perpendicular to the first faces 123 and constitute the other two sides of the rear portion 123, 124 of the second section. The two faces 124 extend forwardly from the third troncon 130 outer diameter D1 inscribed in the rounded edge corner of diameter D as best seen in Figure 6. The second faces 124 extend axially each up to 127. Each stop 127, projecting radially and forming a relief, is in the form of a cylindrical portion of external diameter D 1, at the tolerance set near, that of the fourth trunk 142 and that of the complementary cylindrical portions of the orifice 246 of the movable contact 30. The stops 127 constitute the cylindrical portions of the front portion 123, 127 of the second trunk. These butees are rigid. The front face 126 of each protruding stop 127 serves as a stop at the rear face of the spring 48 supported by its front face on the bottom of the cover 40 of FIG. 1. The two rigid stops 127 replace the stop means 46 before Figure 1 and are therefore before rigid butees here. These two stops 127, consisting of cylindrical portions of outer diameter D, are diametrically opposed and are therefore notched by the faces 124 and this is why we see in Figure 6 the presence of non-reference arms. These arms delimit laterally each second face 124 as well as the rounded corners of the rear portion of the second section 129. These arms have an external periphery implanted on a circumference of diameter D equal to that of the fourth trunk 142. As can be seen from what precedes the second troncon is a troncon passage allowing by its first faces 123 and its cylindrical portions 127 the axial passage of the opening 246 of the movable contact 30. This contact 30 is thus axially threaded on the second troncon (Figure 10 ) against the force exerted by the spring 42 to reach the third section 130 (Figure 11), the spring 42 being threaded in advance on the rod 20. 35 At this first stage the parallel faces of the movable contact 30, formed by the two flat surfaces of the opening 246 of the movable contact, are axially threaded with a mounting clearance on the first faces 123 of the trunk 129 and the spring 42 is compressed axially, this re ssort bearing on the front face 144 of 1 '& paulement 44 and on the rear face 31 of the movable contact acting as a pressure plate and 1' & paulement 44 plateau reaction.
Ce deuxieme troncon 129, appartenant aux moyens d'assemblage du type baionnette, est donc configure pour autoriser un enfilage axial du contact mobile sur ce deuxieme troncon 129. Dans une seconde &tape on utilise le troisieme troncon cylindrique 130 pour effectuer une rotation de 90 du contact mobile 30 et ce a 1'encontre de la force exerc&e par le ressort. Durant cette phase on tourne 1'ouverture 246 du contact mobile 30 et on amene les meplats de cette ouverture 246 en parallelisme avec les deuxiemes faces 124. Bien entendu la longueur axiale du troisieme troncon 130 est au moins &gale a 1'&paisseur du contact mobile 30 au niveau de son orifice 246. Cette longueur est de preference superieure a 1'&paisseur du contact mobile. Le troisieme troncon est donc un troncon de rotation pour le contact mobile 30. Ce troisieme troncon 130, appartenant aux moyens d'assemblage du type baionnette, est donc configure pour autoriser une rotation du contact mobile sur ce troisieme 130 prolongeant vers 1'arriere le deuxieme troncon 129. Dans une troisieme &tape on relache 1'effort axial exerc& auparavant sur la face avant 29 du contact mobile 30 A. 1'aide d'un outil presseur non visible, en sorte que la face avant 29 du contact mobile, sous la sollicitation du ressort 42, vient en butee axial sur les deux faces arrieres 125 des deux butees avant 127 comme visible a la figure 12. En meme temps les deux meplats de l'ouverture 246 du contact mobile 30 cooperent avec les deux deuxiemes faces 124 du deuxieme troncon 129 en sorte que le contact mobile 30 est bloqu& en rotation. This second section 129, belonging to the assembly means of the bayonet type, is thus configured to allow axial threading of the movable contact on the second section 129. In a second stage, the third cylindrical section 130 is used to rotate 90.degree. movable contact 30 against the force exerted by the spring. During this phase the opening 246 of the movable contact 30 is rotated and the flats of this opening 246 are brought into parallelism with the second faces 124. Of course, the axial length of the third section 130 is at least equal to the thickness of the moving contact. 30 at its orifice 246. This length is preferably greater than the thickness of the moving contact. The third section is thus a rotation section for the movable contact 30. This third section 130, belonging to the assembly means of the bayonet type, is configured to allow a rotation of the movable contact on the third 130 extending backward on the second section 129. In a third step is released the axial force exerted previously on the front face 29 of the movable contact 30 A. using a non-visible pressure tool, so that the front face 29 of the movable contact, under the biasing of the spring 42, comes axial stop on the two rear faces 125 of the two stops before 127 as shown in Figure 12. At the same time the two flats of the opening 246 of the movable contact 30 cooperate with the two second faces 124 the second section 129 so that the movable contact 30 is locked in rotation.
Les moyens d'assemblage du type baionnette sont donc configures pour realiser un blocage en rotation du contact mobile par rapport a la tige de commande. Bien entendu la longueur axiale des deuxiemes faces 124 du deuxieme troncon 129 est au moins &gale a l'&paisseur du contact mobile 30 au niveau de son orifice 246. Cette longueur est de preference superieure a celle de 1'&paisseur du contact mobile et depend des applications afin d'autoriser le mouvement axial requis du contact mobile par rapport a la tige 20 pour que ce contact occupe sa position reculee active. Ce deuxieme troncon 129 constitue donc pour le contact mobile 30 un troncon de passage, de bocage axial dans un sens et de blocage en rotation de ce contact monte sur sa tige 20 par un montage du type baionnette, des moyens d'assemblage du type bafonnette intervenant entre le contact mobile 30 et la tige de commande 20 pour montage du contact mobile sur sa tige. Ces moyens font intervenir une rotation, ici de 90 du contact mobile. Cette rotation est realisable de maniere aisee a 1'aide d'un outil. En effet on tire partie de la forme rectangulaire du contact mobile pour saisir par exemple les cotes longitudinaux du contact 30 afin d'effectuer une rotation. L'invention tire partie de la presence du ressort 42 qui sollicite en permanence le contact mobile 30 en direction des butees 127. Cette position de contact sans jeu correspond a la position avancee de repos du contact mobile, qui se deplace axialement sur sa tige 20 pour atteindre une position reculee active lorsque le contact mobile est en contact avec les tetes 32, 34 de la figure 1. The assembly means of the bayonet type are thus configured to realize a rotational locking of the movable contact relative to the control rod. Of course the axial length of the second faces 124 of the second section 129 is at least equal to the thickness of the movable contact 30 at its orifice 246. This length is preferably greater than that of the thickness of the moving contact and depends on applications to allow the required axial movement of the movable contact relative to the rod 20 for this contact to occupy its active retracted position. This second section 129 thus constitutes for the movable contact 30 a troncon passage, axial grooving in one direction and rotational locking of this contact mounted on its rod 20 by a bayonet-type mounting, assembly means of the type bafonnette intervening between the movable contact 30 and the control rod 20 for mounting the movable contact on its rod. These means involve a rotation, here 90 of the movable contact. This rotation can be easily achieved with the aid of a tool. Indeed we take advantage of the rectangular shape of the movable contact to enter for example the longitudinal dimensions of the contact 30 to rotate. The invention takes advantage of the presence of the spring 42 which constantly urges the movable contact 30 towards the stop 127. This contact position without clearance corresponds to the advanced rest position of the movable contact, which moves axially on its rod 20 to reach an active retracted position when the movable contact is in contact with the heads 32, 34 of Figure 1.
Ce montage est stable grace A. la presence des deux butees 127 et des deux faces 124 qui offrent une grande surface ou portee de contact au contact mobile. Ce montage peut titre robotise et fait appel a un outillage simple sans deformation du contact mobile contrairement a un assemblage 25 par sertissage demandant des efforts plus importants. Ce montage peut meme titre realise de maniere manuelle. On appreciera que le deuxieme troncon 129 est obtenu aisement. Par exemple ce troncon est obtenu par fraisage des faces 123, 30 124 a partir d'un troncon cylindrique. En variante l'ouverture 246 du contact 30 et la portion avant complementaire du deuxieme troncon 129 ont une autre forme par exemple une forme cart-6e ou rectangulaire. Les butees 127 saillantes radialement ont en variante une forme 35 complementaire de celle de 1'orifice 246, par exemple carree ou rectangulaire. This arrangement is stable thanks to the presence of two stops 127 and two faces 124 which provide a large surface or contact area to the moving contact. This assembly can robotise title and uses a simple tool without deformation of the movable contact in contrast to a 25 assembly by crimping requiring greater efforts. This assembly can even be done manually. It will be appreciated that the second section 129 is easily obtained. For example this trunk is obtained by milling the faces 123, 124 from a cylindrical section. In a variant, the opening 246 of the contact 30 and the complementary front portion of the second section 129 have another shape, for example a cart-shaped or rectangular shape. The radially projecting stops 127 have a shape complementary to that of the orifice 246, for example square or rectangular.
En variante une seule butee 127, un seul meplat et seulement deux faces 123, 124 sont prevus. Dans ce mode de realisation la ou les butees 127 sont d'un seul tenant avec la tige. Alternatively a single stop 127, a single meplat and only two faces 123, 124 are provided. In this embodiment the stop or stops 127 are in one piece with the rod.
Dans un autre mode de realisation la ou les butees 127 sont rapportees afixation sur la tige. Dans tous les cas la ou les butees 127 sont rigides et solidaires de la tige. Bien entendu dans un autre mode de realisation le montage du type balonnette peut faire intervenir au moins deux ergots saillants radialement a 1'interieur de l'ouverture 246 du contact 30. Ces ergots, par exemple en forme de pattes, sont engages chacun dans une rainure complementaire prevue dans le quatrieme troncon 142 prolonge axialement vers 1'avant en sorte que la presence des troncons 129, 130 n'est pas obligatoire. Les ergots sont dans un mode de realisation diametralement opposes. Dans ce cas chaque rainure presente un premier troncon axial, debouchant a 1'avant du cote du premier troncon 128 et prolonge a son extremite arriere par un troncon circonferentiel de la meme maniere que l'ouverture d'une douille de lampe d'eclairage. Ce troncon circonferentiel est dans un mode de realisation prolonge a son extremite circonferentiel par un deuxieme troncon axial plus court que le premier troncon pour un blocage en rotation du contact mobile sur la tige. In another embodiment, or butees 127 are reported afixation on the rod. In all cases the stop or stops 127 are rigid and integral with the rod. Of course, in another embodiment, the mounting of the balancer type may involve at least two radially projecting lugs inside the opening 246 of the contact 30. These lugs, for example in the form of lugs, are each engaged in a Additional groove provided in the fourth trunk 142 extends axially forward so that the presence of the trunks 129, 130 is not mandatory. The lugs are in an embodiment diametrically opposed. In this case each groove has a first axial section, opening at the front of the side of the first section 128 and extends at its rear end by a circumferential section in the same way as the opening of a lighting lamp socket. This circumferential trunk is in an embodiment extended at its circumferential end by a second axial trunk shorter than the first trunk for locking in rotation of the movable contact on the rod.
Bien entendu la largeur des rainures depend de celle des ergots. Bien entendu, 1'invention ne se limite pas aux modes de realisations decrits precedemment, et elle trouve aussi a s'appliquer pour differentes formes de contacteurs electromagnetiques de puissance. En particulier l'invention s'applique a tous les types de contacteurs pour les moteurs electriques des demarreurs usuels de moteur a combustion interne. Ainsi le contacteur peut titre implante au dessus du moteur electrique du demarreur comme dans le document FR A 2 795 884. En variante le contacteur est deporte en etant par exemple implante transversalement a 1'arriere du moteur electrique du demarreur comme dans le document FR A 2 843 427. Of course, the width of the grooves depends on that of the lugs.

Alternatively the switch is deported for example being implanted transversely to the rear of the electric motor of the starter as in the document FR A 2,843,427.
Le ressort dents contre dents, appele egalement ressort d'engagement, est implante soit dans le contacteur comme a la figure 1, soit a l'exterieur du contacteur entre le lanceur et le levier d'actionnement comme a la figure 1 du document EP B 0 960 276. The spring teeth against teeth, also called engagement spring, is implanted either in the switch as in Figure 1, or outside the contactor between the launcher and the actuating lever as in Figure 1 of EP B 0,960,276.
A la lumiere de ce document on voit que le contacteur peut comporter une bobine de maintien et une bobine d'appel. En variante le contacteur comporte qu'une bobine comme decrit dans le document FR A 2 795 884. En variante un moteur electrique specifique est prevu pour 10 actionner le levier en sorte que le noyau mobile est simplifie en etant depourvu de moyens de liaison avec le levier. La presence du levier d'actionnement n'est pas obligatoire, le moteur electrique du demarreur dans un mode de realisation tournant a vitesse lente par 1'intermediaire d'un enroulement en derivation. In the light of this document it is seen that the contactor may comprise a holding coil and a call coil. As a variant, the contactor comprises a coil as described in document FR A 2 795 884. In a variant, a specific electric motor is provided for actuating the lever so that the mobile core is simplified without being connected to the the sink. The presence of the actuating lever is not obligatory, the electric motor of the starter in an embodiment running at a slow speed by means of a winding in a bypass.
15 Le lanceur est soit a roue libre soit a embrayage a disques multiples. Le demarreur est un demarreur a reducteur de vitesse ou sans reducteur de vitesses. Le lanceur comporte un pignon qui engrene avec une couronne 20 den-tee de demarrage comme decrit dans le document FR A 2 795 884. En variante une transmission a courroie et poulie ou a chaine et roues den-tees intervient entre le demarreur et le vilebrequin du moteur a combustion interne, la roue libre etant par exemple implantee dans la poulie ou la roue den-tee associee au vilebrequin du moteur A. combustion 25 interne, qui peut etre fixe ou appartenir a un vehicule automobile, tel qu'un vehicule de tourisme ou un bateau. Le contacteur electromagnetique pour circuit de puissance selon l'invention peut appartenir a un coupleur de batteries par exemple de telle maniere que deux batteries de 12V connectees auparavant en 30 parallele soit mises en serie pour le demarrage et qu'une tension de 24V existe aux bornes du demarreur. Le contacteur selon 1'invention peut appartenir a un relais de couplage de deux demarreurs agissant en parallele.The launcher is either freewheel or multiple disk clutch. The starter is a starter with speed reducer or without gearbox. The launcher comprises a pinion which meshes with a crown 20 den-tee start as described in the document FR A 2,795,884. Alternatively a transmission belt and pulley or chain and wheels den-tees intervenes between the starter and the crankshaft of the internal combustion engine, the free wheel being for example implanted in the pulley or the den-tee wheel associated with the crankshaft of the engine A. combustion 25, which can be fixed or belong to a motor vehicle, such as a vehicle of tourism or a boat. The electromagnetic contactor for a power circuit according to the invention can belong to a battery coupler for example in such a way that two 12V batteries previously connected in parallel are put in series for start-up and that a voltage of 24V exists at the terminals. of the starter. The contactor according to the invention can belong to a coupling relay of two starters acting in parallel.
