Description

Commutateur d'allumage et de démarrage à contacts frontaux
glissants pour véhicules automobiles
La présente invention a pour objet des
commutateurs d'allumage et de démarrage à contacts
frontaux glissants pour véhicules automobiles.
Ignition and start switch with front contacts
sliding for motor vehicles
The subject of the present invention is
ignition and starter switches with contacts
sliding fronts for motor vehicles.

L'invention concerne plus particulièrement un
commutateur comportant un rotor en matériau
électriquement isolant, portant des contacts mobiles
coopérant,par glissement, avec une série de contacts
fixes portés par un stator en matériau isolant,
accouplé axialement au rotor pour réaliser les
différentes fonctions du commutateur, par des
lamelles de connexion formant lesdits contacts fixes
et reliées à des conducteurs électriques
correspondants. L'invention a pour but de réaliser un
commutateur d'allumage et de démarrage du type
mentionné ci-dessus, dont la fabrication et
l'assemblage soient particulièrement simples et
économiques, et dont le fonctionnement soit sûr et
fiable.
The invention relates more particularly to a
switch comprising a material rotor
electrically insulating, carrying movable contacts
cooperating, by sliding, with a series of contacts
fixed carried by a stator made of insulating material,
axially coupled to the rotor to achieve the
different functions of the switch, by
connection strips forming said fixed contacts
and connected to electrical conductors
correspondents. The invention aims to achieve a
type ignition and start switch
mentioned above, the manufacture and
assembly are particularly simple and
economical, and whose operation is safe and
reliable.

Ce but est atteint suivant l'invention du fait
que
- les contacts mobiles comportent deux
plaquettes conductrices logées de chant, de façon
coulissante, dans deux faces diamétralement alignées
du rotor et pressées, par des ressorts de poussée, en
direction du stator, chacune de ces deux plaquettes
présentant, au niveau de ltextrémité correspondante,
radialement intérieure, un relief axial en saillie
vers le stator et définissant, au droit de son
extrémité radialement extérieure, un bras palpeur,
- le stator présente à proximité de sa
périphérie, des reliefs axiaux incurvés en came, pour
l'appui coulissant desdits bras palpeurs des deux
contacts mobiles, et
- les contacts fixes comprennent un contact
central sur lequel sont disposés, en appui frontal permanent, lesdits reliefs axiaux des deux contacts mobiles, et une série de contacts périphériques placés entre lesdits reliefs à came et contre lesquels, les bras palpeurs des deux contacts mobiles peuvent venir en appui frontal, dans les positions angulaires correspondant à l'absence de ces reliefs à came.
This object is achieved according to the invention because
than
- the mobile contacts have two
conductive plates housed in edge, so
sliding, in two diametrically aligned faces
of the rotor and pressed, by thrust springs, in
direction of the stator, each of these two plates
having, at the corresponding end,
radially inner, a protruding axial relief
towards the stator and defining, in accordance with its
radially outer end, a feeler arm,
- the stator present near its
periphery, cam curved axial reliefs, for
the sliding support of said feeler arms of the two
mobile contacts, and
- fixed contacts include a contact
central on which are arranged, in permanent frontal support, said axial reliefs of the two movable contacts, and a series of peripheral contacts placed between said cam reliefs and against which, the feeler arms of the two movable contacts can come into frontal support, in the angular positions corresponding to the absence of these cam reliefs.

Selon une autre caractéristique de l'invention, la liaison entre chaque lamelle de connexion et le conducteur électrique correspondant est réalisée par insertion de 1' extrémité du conducteur dans une ouverture en oeillet pratiquée dans la lamelle, et par serrage ultérieur de l'ouverture en oeillet, sous l'effet d'une déformation plastique correspondante de la lamelle. According to another characteristic of the invention, the connection between each connection strip and the corresponding electrical conductor is carried out by insertion of the end of the conductor into an eyelet opening made in the strip, and by subsequent tightening of the opening in eyelet, under the effect of a corresponding plastic deformation of the strip.

Diverses autres caractéristiques de l'invention ressortent de la description détaillée qui suit. Un mode de réalisation de l'invention est représenté à titre d'exemple non limitatif, fe-dessnannexé, dans lequel
la figure 1 est une vue schématique en coupe axiale d'un commutateur d'allumage et de démarrage suivant l'invention,
la figure 2 est une vue en coupe le long de la ligne II-II de la figure 1, et
la figure 3 est une vue en perspective-éclatée du commutateur.
Various other characteristics of the invention will emerge from the detailed description which follows. An embodiment of the invention is shown by way of nonlimiting example, fe-dessnannexé, in which
FIG. 1 is a schematic view in axial section of an ignition and start switch according to the invention,
FIG. 2 is a sectional view along the line II-II of FIG. 1, and
Figure 3 is an exploded perspective view of the switch.

Sur les dessins, la référence 1 désigne, dans son ensemble,un commutateur d'allumage et de démarrage à contacts frontaux suivant l'invention, normalement destiné à être associé à un dispositif antivol de blocage de la direction de véhicules automobiles. In the drawings, the reference 1 designates, as a whole, an ignition and starting switch with front contacts according to the invention, normally intended to be associated with an anti-theft device for blocking the steering of motor vehicles.

Le commutateur 1 a une forme générale cylindrique, et est constitué essentiellement d'une base ou stator 2, et d'un rotor 3, réalisés tous deux dans un matériau électriquement isolant et coaxiaux entre eux. Le rotor 3 est assemblé axialement au stator 2, par un corps extérieur 4, permettant la rotation du rotor 3 par rapport au stator 2. Cette rotation est commandée,de manière classique, par des moyens non illustrés. The switch 1 has a generally cylindrical shape, and consists essentially of a base or stator 2, and of a rotor 3, both made of an electrically insulating material and coaxial with each other. The rotor 3 is assembled axially to the stator 2, by an external body 4, allowing the rotation of the rotor 3 relative to the stator 2. This rotation is controlled, in a conventional manner, by means not illustrated.

Le stator 2 présente une paroi de fond 5 ; à proximité de son bord périphérique s'étendent trois reliefs axiaux incurvés en came 6, tournés vers le rotor 3. En outre, dans la paroi de fond, sont pratiquées trois fentes 7 et une autre fente 18 à travers lesquelles s'étendent des lamelles de connexion 8, 9 correspondantes, reliées, comme expliqué ci-après, à des conducteurs électriques 10,
Il correspondants. Les extrémités des lamelles conductrices 8 logées à l'intérieur du commutateur 1, forment des contacts fixes 12 disposés périphériquement, au droit des zones ne comportant pas de reliefs en came 6. Le relief axial des trois contacts fixes périphériques 12 par rapport à la paroi de fond 5, est à peu près semblable à celui des reliefs en came 6.
The stator 2 has a bottom wall 5; near its peripheral edge extend three axial curved reliefs in cam 6, turned towards the rotor 3. In addition, in the bottom wall, three slots 7 and another slot 18 are made through which lamellas extend corresponding connection 8, 9, connected, as explained below, to electrical conductors 10,
There correspondents. The ends of the conductive strips 8 housed inside the switch 1 form fixed contacts 12 disposed peripherally, in line with the zones having no cam reliefs 6. The axial relief of the three peripheral fixed contacts 12 relative to the wall bottom 5, is roughly similar to that of the cam reliefs 6.

En revanche, l'extrémité intérieure de la lamelle de connexion 9 est repliée contre la paroi de fond 5, et forme un contact fixe central 13, de forme à peu près circulaire. On the other hand, the inner end of the connection strip 9 is folded against the bottom wall 5, and forms a central fixed contact 13, of roughly circular shape.

Les extrémités des lamelles 8 et 9 faisant saillie à l'extérieur du commutateur 1, présentent des ouvertures correspondantes en oeillet 14, 15, allongées dans la direction transversale et dans lesquelles s'engagent les extrémités des conducteurs électriques 10, 11. La fixation de ces extrémités se fait par simple serrage des ouvertures 14 et 15, sous l'effet d'une déformation plastique, par compression longitudinale des extrémités libres des lamelles 8 et 9. The ends of the strips 8 and 9 projecting outside the switch 1 have corresponding eyelet openings 14, 15, elongated in the transverse direction and in which the ends of the electrical conductors 10, 11 engage. these ends are made by simply tightening the openings 14 and 15, under the effect of a plastic deformation, by longitudinal compression of the free ends of the strips 8 and 9.

Le conducteur électrique 11 associé au contact fixe central 13, est destiné à être relié à une source électrique d'alimentation, installée à bord d'un véhicule, tandis que les conducteurs 10 associés aux contacts fixes périphériques 12 sont destinés à être reliés aux différents équipements électriques du véhicule. The electrical conductor 11 associated with the central fixed contact 13, is intended to be connected to an electrical power source, installed on board a vehicle, while the conductors 10 associated with the peripheral fixed contacts 12 are intended to be connected to the various vehicle electrical equipment.

Avec les contacts fixes 12 et 13 cooperent deux contacts mobiles 16 portés par le rotor 3. Les deux contacts mobiles 16 sont constitués par deux plaquettes conductrices, logées de chant de façon coulissante, dans deux fentes 17 du rotor 3, tournées vers la paroi de fond 5 du stator 2 et alignées entre elles diamétralement. Chaque plaquette 16 présente au droit de son extrémité radialement intérieure, un relief axial arrondi 19, tourné vers le stator, et forme un bras palpeur 20 au droit-de son extrémité radialement extérieure. With the fixed contacts 12 and 13, two mobile contacts 16 carried by the rotor 3 cooperate. The two mobile contacts 16 consist of two conductive plates, slidably housed in two slots 17 of the rotor 3, facing the wall of the bottom 5 of stator 2 and aligned diametrically therebetween. Each plate 16 has, at the right of its radially inner end, a rounded axial relief 19, facing the stator, and forms a feeler arm 20 at the right of its radially outer end.

Deux ressorts hélicoïdaux de compression 21, logés dans des trous axiaux 22 correspondants du rotor 3, pressent centralement les deux plaquettes 16 vers la paroi de fond 5 du stator 2. Les reliefs axiaux 19 sont ainsi maintenus en permanence en appui frontal contre le contact fixe.central 13, tandis que les bras palpeurs 20 sont pressés en appui frontal, contre les reliefs en came 6, et peuvent venir en appui frontal sur les contacts fixes périphériques 12, sous l'effet de la rotation du rotor 3. Two helical compression springs 21, housed in corresponding axial holes 22 of the rotor 3, press the two plates 16 centrally towards the bottom wall 5 of the stator 2. The axial reliefs 19 are thus permanently maintained in frontal support against the fixed contact .central 13, while the feeler arms 20 are pressed in frontal support, against the cam reliefs 6, and can come into frontal support on the peripheral fixed contacts 12, under the effect of the rotation of the rotor 3.

Pendant le fonctionnement, la rotation du rotor 3 permet de réaliser les différentes fonctions du commutateur 1. En général, ce rotor 3 peut prendre trois positions angulaires, respectivement de repos (dans laquelle l'alimentation des différents appareillages électriques du véhicule est coupée), d'allumage (dans laquelle cette alimentation est autorisée) et de démarrage (dans laquelle le moteur électrique de démarrage du véhicule est actionné). During operation, the rotation of the rotor 3 makes it possible to carry out the various functions of the switch 1. In general, this rotor 3 can take three angular positions, respectively of rest (in which the supply of the various electrical equipment of the vehicle is cut off), ignition (in which this supply is authorized) and starting (in which the electric vehicle starting motor is activated).

Dans la première position, les bras palpeurs 20 sont maintenus en appui sur les reliefs en came 6, de sorte que la liaison - électrique du contact fixe central 13 aux contacts fixes périphériques 12, par les contacts mobiles 16, est interrompue. Lorsque le rotor 3 passe de la première à la deuxième ou à la troisième position, l'abandon des reliefs en came 6 par les bras palpeurs 20, et le positionnement par glissement de ses contacts fixes périphériques 12, suivant des modalités qui correspondent à la disposition de ces contacts fixes, réalisent la fermeture des circuits électriques reliés aux lamelles de connexion 8.In the first position, the feeler arms 20 are held in abutment on the cam reliefs 6, so that the electrical connection from the central fixed contact 13 to the peripheral fixed contacts 12, by the movable contacts 16, is interrupted. When the rotor 3 passes from the first to the second or to the third position, the abandonment of the cam reliefs 6 by the feeler arms 20, and the positioning by sliding of its peripheral fixed contacts 12, according to methods which correspond to the arrangement of these fixed contacts, realize the closing of the electrical circuits connected to the connection strips 8.

I1 ressort à l'évidence de ce qui précède, que le commutateur suivant l'invention est constitué par un nombre restreint de composants pouvant être assemblés entre eux de façon aisée et rapide ; il peut en outre assurer un fonctionnement très efficace et très fiable.  It is evident from the foregoing that the switch according to the invention consists of a limited number of components which can be assembled together easily and quickly; it can also ensure a very efficient and very reliable operation.
