Definitions
- the invention relates to a contactor for a starter of motor vehicle comprising improved means of centering of a fixed core.
- the invention relates more particularly to a contactor for a motor vehicle starter, of the type having a movable magnetic core which moves axially under the effect of a magnetic field created by a coil comprising at least one electrical conductor wound around a coil body, and of the type having a fixed magnetic core which extends transversely to a front axial end of the winding.
- the coil body defines a cylindrical bore inside which the core moves mobile.
- the fixed core has essentially a front transverse wall and an axial section which extends inside the bore delimited by the body of coil, in particular to allow centering of the core by relative to the axis of the magnetic field created by the winding.
- contactors for starter comprising a fixed core produced in the form of a particularly simple and economical cross plate to produce.
- Such flat cores are frequently used in association with electronic control circuits the power supply of the contactor which allow to control the better the magnetic field created by the coil, and so control the movement of the movable core in the contactor.
- the use of such fixed cores poses the problem of centering them with respect to the axis of the coil body and the bore determined by the latter.
- the fixed core is generally crossed by an axial control rod which is integral in translation with the mobile core and which controls the movements of a plate of contact intended to electrically connect two fixed terminals of the contactor, one of which is connected to a storage battery of the vehicle and the other of which powers the starter motor.
- the fixed core is therefore provided with a central bore for the passage of the rod and it is necessary to respect a good coaxiality between the central bore of the fixed core and the bore of the coil body so as not to have to plan too much radial clearance between the control rod and the corresponding bore of the core.
- the object of the invention is therefore to propose new means for centering the core fixed relative to the coil body which allow the use of a flat core.
- the invention provides a starter for motor vehicle, of the type comprising a magnetic core mobile which moves axially under the effect of a field magnetic created by a winding comprising at least one electrical conductor wound around a coil body, and type with a fixed magnetic core which extends transversely to a front axial end of the winding, coil body has a series of pads which extend axially forward from the end front of the coil body, and which are received in corresponding centering holes arranged in the fixed core, characterized in that the pads provide coaxiality between the fixed core and the coil body.
- FIG. 1 shows a contactor 10 for an electric starter for a motor vehicle.
- Contactor 10 comprises a cylindrical housing 12 of axis A1 inside which is housed a coil 14 which is wound around a body of coil 16 of axis A1.
- the winding 14 is constituted by the winding of minus an electrical conductor wire 20 around a wall cylindrical 18 of the coil body 16, between two flanges transverse annular front 22 and rear 24 which delimit axially winding 14.
- the cylindrical wall 18 of the coil body 16 defines a central bore 26 in which a movable core (not shown) moves along the A1 axis under the effect of a field magnetic induced by the winding 14 when it is traversed by an electric current.
- Field lines of the magnetic field created by the winding 14 close in particular thanks to the presence of a fixed magnetic core 28 which is arranged at the front winding 14.
- the core fixed magnetic 28 is produced in the form of a plate annular which is arranged transversely, and which is in abutment axially backwards against a front face 30 of the flange front 22 of the coil body 16.
- the displacements of the mobile core serve to cause the displacements in translation along the axis A1 of an axial rod control 32 which extends through a central bore 34 of the fixed core for pressing on a contact plate 38 against two terminals 40, 42 arranged in a front cover 44 of the contactor.
- the contactor 10 includes improved means for ensuring good coaxiality between the coil body 16 and the core fixed magnetic 28, in particular with a view to perfectly aligning the central bore 26, delimited by the cylindrical wall 18 of the coil body 16, and the central bore 34 of the core 28.

- the pads 46 are received in holes corresponding 48 drilled in the fixed core 28.
- the diameter of the orifices 48 is slightly greater than that of the pads 46 so that the pads 46 do not cooperate with the orifices 48 only by a portion of their lateral surface which is turned towards the axis A1. This ensures a optimum accuracy of relative centering or coaxiality between the coil body 16 and the fixed core 28, in particular avoiding any hyperstatic connection between the two elements.
- the orifices 48 open axially on either side of the core fixed 28 and the pads 46 extend forwards beyond a front face 50 of the fixed core 28.
- the pads 46 can form support points for a printed circuit board 52 which is arranged transversely in the contactor 10, between the fixed core 28 and the contact plate 38, and which carries components electronic control and regulation of electric current traversing the winding 14.
- the plate 52 of annular shape, is thus supported axially rearwards against the front end of the studs 46.
- two of the pads 46 are hollow, i.e. they open axially towards front and axially backwards in the transverse face rear 54 of the front flank 22 of the coil body 16.
- the pads 46 thus provide a passage through the fixed core 28 for an electrical conductor 20 of the winding 14.
- means for connecting the conductor with the printed circuit of the plate 52 are arranged opposite the hollow stud 46 so that the conductor 20 can be directly connected to the control components.

- the barrel 58 has, at its rear axial end, a conical collar which is intended to be clamped axially between the front end of the pad 46 and a rear face of the plate 52.
- the end of the conductor 20 which extends inside the pad 46 is also received in the barrel 58 of the eyelet 56 which extends the stud axially hollow 46.
- the conductor is then connected to the barrel, for example by welding or crimping, so as to ensure on the one hand the electrical connection between the winding 14 and the circuit control, and secondly to ensure the mechanical strength of the eyelet and the plate 52 pressing against the pad 46.
- the pads 46 which are hollow are provided with a slot 60 which opens radially outwards and which extends axially over the entire length of the pad 46 and the front flange 22 of the coil body 16.

Description
L'invention concerne un contacteur pour un démarreur de véhicule automobile comportant des moyens perfectionnés de centrage d'un noyau fixe.The invention relates to a contactor for a starter of motor vehicle comprising improved means of centering of a fixed core.
L'invention concerne plus particulièrement un contacteur pour un démarreur de véhicule automobile, du type comportant un noyau magnétique mobile qui se déplace axialement sous l'effet d'un champ magnétique créé par un bobinage comportant au moins un conducteur électrique enroulé autour d'un corps de bobine, et du type comportant un noyau magnétique fixe qui s'étend transversalement à une extrémité axiale avant du bobinage.The invention relates more particularly to a contactor for a motor vehicle starter, of the type having a movable magnetic core which moves axially under the effect of a magnetic field created by a coil comprising at least one electrical conductor wound around a coil body, and of the type having a fixed magnetic core which extends transversely to a front axial end of the winding.
De manière connue, le corps de bobine délimite un alésage cylindrique à l'intérieur duquel se déplace le noyau mobile.In known manner, the coil body defines a cylindrical bore inside which the core moves mobile.
Selon une conception classique, connue par le document DE-A-19 626 017, le noyau fixe comporte essentiellement une paroi transversale avant et un tronçon axial qui s'étend à l'intérieur de l'alésage délimité par le corps de bobine, notamment pour permettre le centrage du noyau par rapport à l'axe du champ magnétique créé par le bobinage.According to a classic conception, known from document DE-A-19 626 017, the fixed core has essentially a front transverse wall and an axial section which extends inside the bore delimited by the body of coil, in particular to allow centering of the core by relative to the axis of the magnetic field created by the winding.
Toutefois, une telle conception du noyau fixe lui confère des formes géométriques relativement complexes qui en augmentent de manière importante le coût de revient.However, such a fixed core design gives relatively complex geometric shapes which significantly increase the cost price.
Aussi, il a été proposé de réaliser des contacteurs de démarreur comportant un noyau fixe réalisé sous la forme d'une plaque transversale particulièrement simple et économique à produire. De tels noyaux plats sont fréquemment utilisés en association avec des circuits électroniques de commande de l'alimentation du contacteur qui permettent de maítriser au mieux le champ magnétique créé par la bobine, et ainsi de maítriser le déplacement du noyau mobile dans le contacteur. Toutefois, l'utilisation de tels noyaux fixes pose le problème de leur centrage par rapport à l'axe du corps de bobine et de l'alésage déterminé par ce dernier.Also, it has been proposed to make contactors for starter comprising a fixed core produced in the form of a particularly simple and economical cross plate to produce. Such flat cores are frequently used in association with electronic control circuits the power supply of the contactor which allow to control the better the magnetic field created by the coil, and so control the movement of the movable core in the contactor. However, the use of such fixed cores poses the problem of centering them with respect to the axis of the coil body and the bore determined by the latter.
En effet, le noyau fixe est généralement traversé par une tige de commande axiale qui est solidaire en translation du noyau mobile et qui commande les déplacements d'une plaque de contact destinée à relier électriquement deux bornes fixes du contacteur dont l'une est reliée à une batterie d'accumulateurs du véhicule et dont l'autre alimente le moteur du démarreur. Indeed, the fixed core is generally crossed by an axial control rod which is integral in translation with the mobile core and which controls the movements of a plate of contact intended to electrically connect two fixed terminals of the contactor, one of which is connected to a storage battery of the vehicle and the other of which powers the starter motor.
Le noyau fixe est donc muni d'un perçage central pour le passage de la tige et il est nécessaire de respecter une bonne coaxialité entre le perçage central du noyau fixe et l'alésage du corps de bobine pour ne pas être obligé de prévoir un jeu radial trop important entre la tige de commande et l'alésage correspondant du noyau.The fixed core is therefore provided with a central bore for the passage of the rod and it is necessary to respect a good coaxiality between the central bore of the fixed core and the bore of the coil body so as not to have to plan too much radial clearance between the control rod and the corresponding bore of the core.
L'invention a donc pour but de proposer de nouveaux moyens de centrage du noyau fixe par rapport au corps de bobine qui permettent l'utilisation d'un noyau plat.The object of the invention is therefore to propose new means for centering the core fixed relative to the coil body which allow the use of a flat core.
Dans ce but, l'invention propose un démarreur de véhicule automobile, du type comportant un noyau magnétique mobile qui se déplace axialement sous l'effet d'un champ magnétique créé par un bobinage comportant au moins un conducteur électrique enroulé autour d'un corps de bobine, et du type comportant un noyau magnétique fixe qui s'étend transversalement à une extrémité axiale avant du bobinage, corps de bobine comporte une série de plots qui s'étendent axialement vers l'avant depuis l'extrémité axiale avant du corps de bobine, et qui sont reçus dans des orifices de centrage correspondants aménagés dans le noyau fixe, caractérisé en ce que les plots assurent une coaxialité entre le noyau fixe et le corps de bobine.To this end, the invention provides a starter for motor vehicle, of the type comprising a magnetic core mobile which moves axially under the effect of a field magnetic created by a winding comprising at least one electrical conductor wound around a coil body, and type with a fixed magnetic core which extends transversely to a front axial end of the winding, coil body has a series of pads which extend axially forward from the end front of the coil body, and which are received in corresponding centering holes arranged in the fixed core, characterized in that the pads provide coaxiality between the fixed core and the coil body.

On a représenté sur la figure 1 un contacteur 10 pour
un démarreur électrique de véhicule automobile. Le contacteur 10
comporte un boítier cylindrique 12 d'axe A1 à l'intérieur duquel
est logé un bobinage 14 qui est enroulé autour d'un corps de
bobine 16 d'axe A1.FIG. 1 shows a
Le bobinage 14 est constitué par l'enroulement d'au
moins un fil 20 conducteur de l'électricité autour d'une paroi
cylindrique 18 du corps de bobine 16, entre deux flasques
transversaux annulaires avant 22 et arrière 24 qui délimitent
axialement le bobinage 14.The
La paroi cylindrique 18 du corps de bobine 16 délimite
un alésage central 26 dans lequel un noyau mobile (non
représenté) se déplace selon l'axe A1 sous l'effet d'un champ
magnétique induit par le bobinage 14 lorsqu'il est parcouru par
un courant électrique. Les lignes de champ du champ magnétique
créé par le bobinage 14 se referment notamment grâce à la
présence d'un noyau magnétique fixe 28 qui est agencé à l'avant
du bobinage 14.The
Dans l'exemple de réalisation de l'invention, le noyau
magnétique fixe 28 est réalisé sous la forme d'une plaque
annulaire qui est agencée transversalement, et qui est en appui
axialement vers l'arrière contre une face avant 30 du flasque
avant 22 du corps de bobine 16.In the embodiment of the invention, the core
fixed magnetic 28 is produced in the form of a plate
annular which is arranged transversely, and which is in abutment
axially backwards against a
Les déplacements du noyau mobile servent à provoquer
les déplacements en translation selon l'axe A1 d'une tige axiale
de commande 32 qui s'étend au travers d'un perçage central 34 du
noyau fixe pour solliciter une plaque de contact 38 en appui
contre deux bornes 40, 42 agencées dans un capot avant 44 du
contacteur.The displacements of the mobile core serve to cause
the displacements in translation along the axis A1 of an
Conformément aux enseignements de l'invention, le
contacteur 10 comporte des moyens perfectionnés pour assurer une
bonne coaxialité entre le corps de bobine 16 et le noyau
magnétique fixe 28, notamment en vue d'aligner parfaitement
l'alésage central 26, délimité par la paroi cylindrique 18 du
corps de bobine 16, et le perçage central 34 du noyau 28.In accordance with the teachings of the invention, the
A cet effet, le corps de bobine 16 comporte une série
de plots cylindriques 46 qui s'étendent axialement vers l'avant
depuis la face avant 30 du flasque avant 22 du corps de bobine
16.For this purpose, the
Les plots 46, au nombre de trois et répartis angulairement
à 120° autour de l'axe A1, sont reçus dans des orifices
correspondants 48 percés dans le noyau fixe 28. The
Comme on peut le voir plus particulièrement sur la
figure 2, le diamètre des orifices 48 est légèrement supérieur à
celui des plots 46 de manière que les plots 46 ne coopèrent avec
les orifices 48 que par une portion de leur surface latérale qui
est tournée en direction de l'axe A1. On assure ainsi une
précision optimale du centrage relatif ou de la coaxialité entre
le corps de bobine 16 et le noyau fixe 28, en évitant notamment
toute liaison hyperstatique entre les deux éléments.As we can see more particularly on the
FIG. 2, the diameter of the
Comme on peut le voir sur les figures 1 et 2, les
orifices 48 débouchent axialement de part et d'autre du noyau
fixe 28 et les plots 46 s'étendent vers l'avant au-delà d'une
face avant 50 du noyau fixe 28.As can be seen in Figures 1 and 2, the
Ainsi, les plots 46 peuvent former des points d'appui
pour une plaque à circuit imprimé 52 qui est agencée
transversalement dans le contacteur 10, entre le noyau fixe 28
et la plaque de contact 38, et qui porte des composants
électroniques de commande et de régulation du courant électrique
parcourant le bobinage 14.Thus, the
La plaque 52, de forme annulaire, est ainsi en appui
axialement vers l'arrière contre l'extrémité avant des plots 46.The
Selon un autre aspect de l'invention, deux des plots 46
sont creux, c'est-à-dire qu'ils débouchent axialement vers
l'avant et axialement vers l'arrière dans la face transversale
arrière 54 du flanc avant 22 du corps de bobine 16.According to another aspect of the invention, two of the
Les plots 46 ménagent ainsi un passage au travers du
noyau fixe 28 pour un conducteur électrique 20 du bobinage 14.The
De manière avantageuse, des moyens de raccordement du
conducteur avec le circuit imprimé de la plaque 52 sont agencés
en regard du plot creux 46 de manière que le conducteur 20
puisse être directement raccordé aux composants de commande.Advantageously, means for connecting the
conductor with the printed circuit of the
La plaque 52 est ainsi munie d'un oeillet de
raccordement 56 qui comporte un fût cylindrique axial 58 engagé
au travers d'une perforation 59 de la plaque 52. Le fût 58
comporte, à son extrémité axiale arrière, un collet conique qui
est destiné à être serré axialement entre l'extrémité avant du
plot 46 et une face arrière de la plaque 52.The
De la sorte, il est prévu que l'extrémité du conducteur
20 qui s'étend à l'intérieur du plot 46 soit également reçue
dans le fût 58 de l'oeillet 56 qui prolonge axialement le plot
creux 46. Le conducteur est alors relié au fût, par exemple par
soudage ou par sertissage, de manière à assurer d'une part la
liaison électrique entre le bobinage 14 et le circuit de
commande, et d'autre part à assurer la tenue mécanique de
l'oeillet et de la plaque 52 en appui contre le plot 46.In this way, it is expected that the end of the
Avantageusement, les plots 46 qui sont creux sont
pourvus d'une fente 60 qui débouche radialement vers l'extérieur
et qui s'étend axialement sur toute la longueur du plot 46 et du
flasque avant 22 du corps de bobine 16.Advantageously, the
De la sorte, lorsque le fil conducteur 20 est enroulé
autour de la paroi cylindrique 18 du corps de bobine 16, les
extrémités du conducteur 20 qui doivent être reliées à la plaque
à circuit imprimé 52 sont engagées radialement de l'extérieur
vers l'intérieur dans les plots creux 46, au travers de la fente
60. On évite ainsi d'avoir à enfiler le fil axialement dans le
plot 46.In this way, when the
