Description

La présente invention concerne un interrupteur électrique rotatif à positions multiples, notamment pour un antivol de véhicule automobile.The present invention relates to a switch electric rotary multi-position, especially for a motor vehicle anti-theft device.

L'invention concerne un interrupteur manoeuvrable à l'aide de la clé de contact au gré de l'utilisateur et qui, en fonction de l'orientation angulaire de la clé, établit différents circuits électriques nécessaires au démarrage et au fonctionnement du véhicule, ainsi qu'à son arrêt.The invention relates to a switch operable with using the ignition key at the option of the user and who, in depending on the angular orientation of the key, establishes different electrical circuits required for starting and vehicle operation, as well as when stopped.

L'invention est relative à un interrupteur du type comportant un boítier de forme générale cylindrique qui comporte :

  • un tronçon avant ouvert axialement formant une chambre de contact, délimitée transversalement par un fond et latéralement par une jupe cylindrique, dans laquelle est monté un rotor qui porte un contact mobile susceptible d'établir, en fonction de la position angulaire (déterminée par la clé de contact qui agit sur le rotor), des raccordements électriques entre différents contacts fixes agencés dans le fond de la chambre de contact ; et
  • un tronçon arrière massif comportant un passage central, coaxial au boítier, et des passages périphériques agencés à proximité de la face latérale cylindrique convexe du tronçon arrière, dont chacun débouche à ses deux extrémités axiales opposées et reçoit un contact fixe et un fil conducteur associé relié au contact fixe.
The invention relates to a switch of the type comprising a housing of generally cylindrical shape which comprises:
  • an axially open front section forming a contact chamber, delimited transversely by a bottom and laterally by a cylindrical skirt, in which is mounted a rotor which carries a movable contact capable of establishing, as a function of the angular position (determined by the key contact which acts on the rotor), electrical connections between different fixed contacts arranged in the bottom of the contact chamber; and
  • a solid rear section comprising a central passage, coaxial with the housing, and peripheral passages arranged near the convex cylindrical lateral face of the rear section, each of which opens at its two opposite axial ends and receives a fixed contact and an associated conductive wire connected fixed contact.

Selon une conception connue d'un tel interrupteur, décrite et représentée dans le document FR-A-2.701.160, le boítier est une pièce massive qui comporte les différents passages pour les contacts fixes et à laquelle est associé un couvercle qui est rapporté à l'une des extrémités axiales du boítier massif et dont la paroi latérale en forme de jupe délimite la chambre de contact dans laquelle est montée le rotor.According to a known design of such a switch, described and represented in document FR-A-2.701.160, the case is a massive piece that includes the different passages for fixed contacts and to which is associated a cover which is attached to one of the axial ends of the solid housing and whose side wall in the form of a skirt delimits the contact chamber in which the rotor.

Cette conception rend l'assemblage des différents composants particulièrement complexe et elle ne permet notamment pas son automatisation la plus complète possible. De plus, une fois les contacts fixes et le contact mobile en place et après la pose du couvercle, la paroi cylindrique latérale du boítier demeure une paroi incomplète et le composant constitué par l'interrupteur nécessite d'être implanté dans une enveloppe complémentaire, c'est à dire qu'il ne constitue pas un composant complet et autonome pouvant être implanté avec la plus grande liberté possible en association avec un antivol.This design makes the assembly of different particularly complex components and it only allows especially not its most complete automation possible. In addition, once the fixed contacts and the movable contact in place and after fitting the cover, the cylindrical wall side of the case remains an incomplete wall and the component constituted by the switch needs to be implanted in an additional envelope, i.e. it does not constitute a complete and autonomous component which can be established with the greatest possible freedom in combination with a lock.

Selon une autre conception connue, tous les passages qui reçoivent les contacts fixes sont réalisés sous la forme de canaux d'orientation axiale dans lesquels les contacts fixes sont introduits axialement.According to another known concept, all the passages which receive the fixed contacts are made in the form of axial orientation channels in which the fixed contacts are introduced axially.

Chaque contact fixe est introduit axialement depuis l'extrémité arrière du canal associé vers son extrémité avant qui débouche dans le fond de la chambre de contact.Each fixed contact is introduced axially from the rear end of the associated channel towards its front end which opens into the bottom of the contact chamber.

Chaque contact fixe se termine par une extrémité libre avant découpée et de profil arrondi qui fait saillie axialement dans le fond de la chambre de contact pour constituer la surface de contact fixe avec laquelle coopère le contact mobile.Each fixed contact ends with a free end front cut and rounded profile which projects axially in the bottom of the contact chamber to constitute the fixed contact surface with which the contact cooperates mobile.

Une telle conception présente de nombreux inconvénients.Such a design presents many disadvantages.

La zone de contact fixe est constituée par un bord arrondi découpé et l'état de surface de cette zone de contact fixe avec laquelle coopère par frottement une zone de contact formée en vis-à-vis sur le contact mobile rotatif, est peu satisfaisant du point de vue électrique et provoque une usure prématurée des zones de contact.The fixed contact area consists of an edge rounded cut and the surface condition of this contact area fixed with which a contact zone cooperates by friction formed opposite the rotary movable contact, is little electrically satisfactory and causes wear premature contact areas.

L'introduction axiale de chaque contact fixe et son blocage en position montée par un doigt transversal de blocage du capot ne permettent pas de maítriser de manière précise la position axiale du contact fixe par rapport au boítier et donc la position de la zone de contact fixe d'extrémité par rapport au fond transversal de la chambre de contact.The axial introduction of each fixed contact and its locking in the mounted position by a transverse finger of hood blocking do not allow to control specifies the axial position of the fixed contact with respect to the housing and therefore the position of the fixed end contact area by relative to the transverse bottom of the contact chamber.

Par ailleurs, le blocage axial en position montée de chaque contact fixe est insuffisant dans la mesure où il est assuré par la coopération du doigt de blocage avec deux surfaces opposées de butée formées dans un bord longitudinal du contact fixe en forme de plaquette constituées par les bords latéraux d'une encoche formée dans ce bord longitudinal.Furthermore, the axial locking in the mounted position of each fixed contact is insufficient to the extent that it is ensured by the cooperation of the locking finger with two opposite abutment surfaces formed in a longitudinal edge fixed contact in the form of a plate formed by the edges lateral of a notch formed in this longitudinal edge.

Il existe un jeu fonctionnel trop important entre les surfaces de butée et les portions en vis-à-vis du doigt de blocage associé.There is too much functional play between the abutment surfaces and the portions facing the finger associated blockage.

Afin d'assurer un positionnement axial correct de chaque contact fixe, les doigts de blocage du capot comportent des rampes qui, lors du mouvement d'introduction transversale des doigts de blocage, sont usées par frottement contre les bords de l'encoche de blocage de la plaquette du contact fixe correspondant.In order to ensure correct axial positioning of each fixed contact, the hood locking fingers have ramps which, during the transverse insertion movement locking fingers are worn by friction against edges of the locking notch of the fixed contact plate corresponding.

Lors de l'introduction axiale de chaque contact fixe, les bords longitudinaux et d'extrémité avant de ceux-ci constituent autant d'arêtes qui détériorent les parois environnantes du passage formé dans le corps massif en matière plastique isolante et aboutissent à la formation de copeaux de matière plastique qui sont introduits dans la chambre de contact et qui peuvent empêcher un bon fonctionnement ultérieur de l'interrupteur. During the axial insertion of each fixed contact, the longitudinal and front end edges of these constitute as many edges which deteriorate the surrounding walls of the passage formed in the massive plastic body insulating and lead to the formation of material chips plastic which are introduced into the contact chamber and which may prevent further operation of the switch.

La conception selon l'état de la technique ne permet pas non plus d'assurer un détrompage entre les différents contacts fixes, et notamment les contacts périphériques et elle aboutit parfois à un montage incorrect des contacts fixes aboutissant à un défaut de fabrication de l'interrupteur.The state-of-the-art design does not allow also not to ensure a polarization between the different fixed contacts, including peripheral contacts and it sometimes results in incorrect mounting of the fixed contacts resulting in a manufacturing defect in the switch.

Enfin, le pilotage du contact mobile rotatif, également appelé curseur, est parfois insuffisant notamment pour la détermination de certaines de ses positions angulaires par rapport aux contacts fixes.Finally, the control of the rotary mobile contact, also called cursor, is sometimes insufficient especially for the determination of some of its angular positions by compared to fixed contacts.

La présente invention a pour but de proposer une nouvelle conception d'un interrupteur électrique du type mentionné précédemment qui remédie à ces inconvénients, et qui permet notamment de réaliser un interrupteur à boítier complet et permettant un montage simplifié des contacts fixes.The object of the present invention is to provide a new design of an electric switch of the type previously mentioned which overcomes these disadvantages, and which makes it possible in particular to produce a switch with a housing complete and allowing simplified mounting of fixed contacts.

L'interrupteur d'antivol 30 illustré à la figure 1 est un interrupteur rotatif, d'axe X-X, à positions multiples.The anti-theft switch 30 illustrated in FIG. 1 is a rotary switch, X-X axis, multi-position.

Il est constitué pour l'essentiel par un boítier en deux parties 32 et 34, par un rotor 36 et par une platine 38.It mainly consists of a housing in two parts 32 and 34, by a rotor 36 and by a plate 38.

Selon une conception connue, le rotor 36 comporte un logement 40 qui reçoit un contact mobile rotatif 42, appelé curseur, en forme générale de V à deux branches 44 et 46 qui est prévu pour établir, en fonction de la position angulaire du rotor 36, différents contacts électriques entre un contact fixe central 48 qui, comme cela sera expliqué par la suite, est toujours en contact avec la partie centrale 49 du contact mobile 42 et trois contacts fixes périphériques 50A, 50B et 50C.According to a known design, the rotor 36 includes a housing 40 which receives a rotary movable contact 42, called cursor, in general V shape with two branches 44 and 46 which is intended to establish, depending on the angular position of the rotor 36, different electrical contacts between a fixed contact central 48 which, as will be explained below, is always in contact with the central part 49 of the contact mobile 42 and three peripheral fixed contacts 50A, 50B and 50C.

Le contact fixe central 48 est relié à la borne positive de la batterie du véhicule équipé de l'antivol, le contact périphérique 50A est relié au circuit d'alimentation du démarreur, le contact 50B est relié à la bobine et le contact périphérique 50C est relié au circuit d'alimentation d'accessoires électriques du véhicule.The central fixed contact 48 is connected to the positive terminal of the battery of the vehicle fitted with the anti-theft device, the ignition peripheral 50A is connected to the power supply circuit of the starter, contact 50B is connected to the coil and contact device 50C is connected to the power circuit vehicle electrical accessories.

Selon une conception connue, le rotor 36 assure également l'entraínement en rotation d'une plaquette de contact 52 reçue dans un logement 54 du rotor 36 et qui établit un contact électrique entre deux bornes fixes diamétralement opposées 56 portées par la platine 38 et qui sont reliées au circuit d'allumage du moteur du véhicule.According to a known design, the rotor 36 provides also the rotational drive of a wafer contact 52 received in a housing 54 of the rotor 36 and which establishes an electrical contact between two diametrically fixed terminals opposite 56 carried by the plate 38 and which are connected to the vehicle engine ignition system.

Les deux parties 32 et 34 du boítier de l'interrupteur, le rotor 36 et la platine 38 sont réalisés en matériau isolant de l'électricité, par exemple par moulage en matière plastique.The two parts 32 and 34 of the switch housing, the rotor 36 and plate 38 are made of insulating material electricity, for example by plastic molding.

Conformément aux enseignements de l'invention, la première partie 32 du boítier formant corps est une pièce moulée en matière plastique qui comporte un tronçon arrière massif 58 et un tronçon avant 60 d'épaisseur réduite réalisée sous la forme d'une demi-jupe semi-cylindrique 62.In accordance with the teachings of the invention, the first part 32 of the housing forming a body is a part molded from plastic which has a rear section solid 58 and a front section 60 of reduced thickness produced in the form of a semi-cylindrical half-skirt 62.

Le tronçon arrière massif 58 est délimité par une paroi latérale 64 de forme générale semi-cylindrique convexe et par un fond transversal 66 qui s'étend dans un plan diamétral et à partir duquel s'étend axialement la demi-jupe 62.The solid rear section 58 is delimited by a wall lateral 64 of generally semi-cylindrical convex shape and by a transverse bottom 66 which extends in a diametral plane and at from which the half-skirt 62 extends axially.

Le fond transversal 66 et la demi-jupe 62 du tronçon avant 60 délimitent en partie une chambre de contact 68 qui est ouverte axialement et dans laquelle est monté à rotation le rotor 36 avec le curseur rotatif 42 et la plaquette 52.The transverse bottom 66 and the half-skirt 62 of the section before 60 partially define a contact chamber 68 which is open axially and in which the rotation is mounted rotor 36 with the rotary cursor 42 and the plate 52.

Le tronçon arrière massif 58 est délimité par une paroi extérieure sensiblement plane 70 qui s'étend sensiblement dans le plan axial passant par les bords longitudinaux d'extrémité 72 de la demi-jupe 62 du corps 32.The solid rear section 58 is delimited by a wall substantially planar exterior 70 which extends substantially in the axial plane passing through the longitudinal edges end 72 of the half-skirt 62 of the body 32.

Le tronçon arrière massif 58 est également délimité par une face transversale arrière d'extrémité axiale 74 perpendiculaire à l'axe X-X et parallèle au fond 66.The massive rear section 58 is also delimited by a perpendicular rear transverse end face 74 perpendicular to the X-X axis and parallel to the bottom 66.

La demi-jupe 62 est délimitée par un bord annulaire d'extrémité axiale 76.The half-skirt 62 is delimited by an annular edge axial end 76.

Le tronçon arrière massif 58 comporte un passage central 78 d'orientation axiale qui débouche à ses extrémités axiales avant et arrière dans le fond 66 et dans la face 74.The massive rear section 58 has a passage central 78 of axial orientation which opens at its ends axial front and rear in the bottom 66 and in the face 74.

Le passage central 78 est réalisé sous la forme d'un canal et il est destiné à recevoir, par introduction d'arrière en avant, c'est-à-dire de la droite vers la gauche en considérant la figure 5, le contact fixe central 48 avec son fil électrique de raccordement 48A.The central passage 78 is produced in the form of a channel and it is intended to receive, by introduction from rear to before, i.e. from right to left considering Figure 5, the central fixed contact 48 with its electric wire 48A connection.

Le tronçon arrière comporte également trois passages périphériques 80A, 80B et 80C dont chacun est destiné à recevoir respectivement le contact fixe périphérique 50A, 50B, 50C avec son fil électrique de raccordement 51A, 51B, 51C. The rear section also has three passages peripherals 80A, 80B and 80C each of which is intended for receive respectively the peripheral fixed contact 50A, 50B, 50C with its electrical connection wire 51A, 51B, 51C.

Chaque passage périphérique 80A, 80B, 80C s'étend axialement et est ouvert à ses deux extrémités opposées dans le fond transversal 66 et dans la face transversale arrière 74.Each peripheral passage 80A, 80B, 80C extends axially and is open at its two opposite ends in the transverse bottom 66 and in the rear transverse face 74.

Conformément à une caractéristique de l'invention, chaque passage périphérique est ouvert radialement vers l'extérieur dans la face latérale cylindrique convexe 64 du tronçon arrière massif 58.In accordance with a characteristic of the invention, each peripheral passage is open radially towards the outside in the convex cylindrical side face 64 of the massive rear section 58.

Chaque passage périphérique comporte une portion arrière de forme générale semi-cylindrique concave 82A, 82B, 82C qui est destinée à recevoir le conducteur électrique correspondant 51A, 51B, 51C et la cosse arrière de sertissage 84A, 84B, 84C du contact fixe associé.Each peripheral passage has a portion rear generally concave semi-cylindrical 82A, 82B, 82C which is intended to receive the electrical conductor corresponding 51A, 51B, 51C and the rear crimp terminal 84A, 84B, 84C of the associated fixed contact.

La portion avant 86A, 86B, 86C de chaque passage périphérique est réalisée sous la forme d'une glissière de section rectangulaire ouverte radialement vers l'extérieur et délimitée radialement vers l'intérieur par un fond 88A, 88B, 88C.The front portion 86A, 86B, 86C of each pass device is made in the form of a slide rectangular section open radially outward and delimited radially inwards by a bottom 88A, 88B, 88C.

Chaque portion avant 86A, 86B, 86C est délimitée latéralement par deux glissières longitudinales parallèles 90A, 90B, 90C.Each front portion 86A, 86B, 86C is delimited laterally by two parallel longitudinal slides 90A, 90B, 90C.

Comme on peut le voir notamment sur la figure 7, la largeur transversale de la portion avant en forme de glissière 86A du passage 80A est inférieure à la largeur transversale des portions avant 86B, 86C des passages périphériques 80B et 80C qui sont égales entre elles.As can be seen in particular in FIG. 7, the transverse width of the front portion in the form of a slide 86A of passage 80A is less than the transverse width front portions 86B, 86C of peripheral passages 80B and 80C which are equal to each other.

Les bords en vis-à-vis des glissières longitudinales 90A, 90B et 90C comportent des crans opposés et alignés 92A, 92B, 92C.The edges facing the longitudinal slides 90A, 90B and 90C have opposite and aligned notches 92A, 92B, 92C.

Les deux crans 92A présentent une même largeur longitudinale, c'est-à-dire mesurée parallèlement à l'axe X-X, et ils débouchent transversalement dans les crans en vis-à-vis 92C et 92B. The two notches 92A have the same width longitudinal, i.e. measured parallel to the X-X axis, and they open transversely in the notches opposite 92C and 92B.

Comme on peut le voir notamment sur la figure 4, les deux crans opposés 92C et les deux crans opposés 92B sont de largeur longitudinale différente pour constituer, comme cela sera expliqué par la suite, des moyens de détrompage.As can be seen in particular in FIG. 4, the two opposite notches 92C and the two opposite notches 92B are of different longitudinal width to constitute, like this will be explained later, polarization means.

Chacun des fonds intérieurs 88A, 88B, 88C des portions avant des passages périphériques 80A, 80B, 80C s'étend sensiblement dans un plan tangentiel, c'est-à-dire dans un plan perpendiculaire à un rayon correspondant.Each of the interior bottoms 88A, 88B, 88C of the portions before peripheral passages 80A, 80B, 80C extends substantially in a tangential plane, that is to say in a plane perpendicular to a corresponding radius.

Chacun de ces fonds comporte une dépression 94A, 94B, 94C agencée axialement en regard des crans correspondants et qui se termine axialement vers l'arrière par une rampe inclinée 96A, 96B, 96C.Each of these funds has a depression 94A, 94B, 94C arranged axially opposite the notches corresponding and which ends axially backwards with an inclined ramp 96A, 96B, 96C.

Les rampes 96A, 96B, 96C se terminent au voisinage du bord transversal arrière 98A, 98B, 98C des fonds 88A, 88B, 88C.Ramps 96A, 96B, 96C end in the vicinity of rear transverse edge 98A, 98B, 98C of bottoms 88A, 88B, 88C.

La paroi latérale 64 du tronçon arrière 58 s'étend axialement au-delà du fond transversal 66 sous la forme d'un bord annulaire 100 qui comporte trois plots d'appui en relief 102A, 102B, 102C alignés axialement respectivement avec les trois passages périphériques et qui sont situés dans un même plan transversal.The side wall 64 of the rear section 58 extends axially beyond the transverse bottom 66 in the form of a annular edge 100 which has three raised support pads 102A, 102B, 102C aligned axially respectively with the three peripheral passages which are located in the same transverse plane.

Le tronçon arrière se prolonge également axialement vers l'intérieur de la demi-jupe cylindrique 62 sous la forme d'une couronne semi-cylindrique 104 dont le bord d'extrémité axiale avant 106 comporte deux crans d'arrêt adjacents 108 avec des rampes 110, l'écart angulaire entre les deux crans correspondant à l'écart entre les deux branches du curseur.The rear section also extends axially towards the inside of the cylindrical half-skirt 62 in the form a semi-cylindrical crown 104 whose end edge front axial 106 has two adjacent locking stops 108 with ramps 110, the angular distance between the two notches corresponding to the distance between the two branches of the cursor.

Le passage central 78 comporte une portion arrière de forme générale semi-cylindrique 82 destinée à recevoir la cosse 84 du contact fixe central 48 et son conducteur électrique associé 48A. The central passage 78 has a rear portion of general semi-cylindrical shape 82 intended to receive the terminal 84 of the central fixed contact 48 and its conductor associated electric 48A.

II comporte également une portion d'extrémité avant de section rectangulaire 86.It also includes a front end portion of rectangular section 86.

La portion d'extrémité arrière 82 est délimitée longitudinalement par deux glissières opposées 90 de section rectangulaire et qui s'étendent latéralement sur des longueurs différentes, par rapport à l'axe X-X, comme on peut le voir sur la figure 7.The rear end portion 82 is delimited longitudinally by two opposite slides 90 of section rectangular and extending laterally over lengths different, compared to the X-X axis, as we can see on Figure 7.

La portion arrière 82 avec ses glissières longitudinales 90 est délimitée axialement vers l'avant par un fond transversal 112.The rear portion 82 with its longitudinal slides 90 is delimited axially forwards by a bottom transverse 112.

La face latérale cylindrique 64 du tronçon arrière 58 comporte deux autres passages débouchant radialement et diamétralement opposés 114 destinés à recevoir les cosses 116 des contacts fixes d'allumage 56 avec leurs fils conducteurs associés 118.The cylindrical lateral face 64 of the rear section 58 has two other passages opening radially and diametrically opposed 114 intended to receive the terminals 116 fixed ignition contacts 56 with their wires associated conductors 118.

On décrira maintenant en détail le capot 34 illustré notamment aux figures 3 et 8 à 12.The cover 34 illustrated will now be described in detail. especially in Figures 3 and 8 to 12.

Le capot 34 est constitué pour l'essentiel par une paroi latérale semi-cylindrique arrière 120 qui, en position assemblée du capot 34 sur le corps 32, est prévue pour s'étendre en regard de la face latérale cylindrique convexe 64 du corps 32, et par une seconde demi-jupe semi-cylindrique 122 complémentaire de la demi-jupe 62 du corps 32, c'est-à-dire qui, en position assemblée, constitue avec cette dernière une jupe latérale cylindrique qui délimite la chambre de contact 68 en association avec le fond transversal 66.The cover 34 consists essentially of a wall rear semi-cylindrical side 120 which, in position assembly of the cover 34 on the body 32, is provided for extend opposite the convex cylindrical side face 64 of the body 32, and by a second semi-cylindrical half-skirt 122 complementary to the half-skirt 62 of the body 32, that is to say which, in the assembled position, constitutes with the latter a cylindrical side skirt which delimits the contact 68 in association with the transverse bottom 66.

Le bord annulaire 124 qui délimite la jupe 122 par rapport à la paroi latérale 120 est prévu pour venir en regard du bord annulaire 100 de la paroi latérale 64.The annular edge 124 which delimits the skirt 122 by compared to the side wall 120 is intended to come opposite of the annular edge 100 of the side wall 64.

La demi-jupe 122 comporte une fenêtre 126 qui, en position assemblée, est diamétralement opposée à une fenêtre symétrique 127 formée dans la demi-jupe 62, ces deux fenêtres étant prévues pour recevoir les pattes diamétrales opposées 128 de la platine 38 pour le maintien et la fixation de cette dernière dans le boítier.The half-skirt 122 has a window 126 which, in assembled position, is diametrically opposite a window symmetrical 127 formed in the half-skirt 62, these two windows being provided to receive the diametrical tabs opposite 128 of the plate 38 for the maintenance and fixing of the latter in the housing.

Au voisinage de son bord transversal arrière 124, la face concave interne de la demi-jupe 122 du capot 34 comporte deux rampes en relief 130 qui sont prévues pour coopérer avec les becs 133 des branches 44 et 46 du curseur 42 pour commander les déplacements de ce dernier par rapport aux contacts fixes lors de sa rotation.In the vicinity of its rear transverse edge 124, the internal concave face of the half-skirt 122 of the cover 34 comprises two raised ramps 130 which are provided for cooperate with the beaks 133 of the branches 44 and 46 of the cursor 42 to control the movements of the latter by relative to the fixed contacts during its rotation.

La demi-jupe 122 est délimitée par deux bords longitudinaux opposés 132 qui, en position assemblée, sont en regard des bords 72 de la demi-jupe 62 du corps 32.The half-skirt 122 is delimited by two edges opposite longitudinal sections 132 which, in the assembled position, are in look at the edges 72 of the half-skirt 62 of the body 32.

La demi-jupe 122 est également délimitée axialement par un bord annulaire avant 134 complémentaire du bord annulaire avant 76 de la demi-jupe 62.The half-skirt 122 is also delimited axially by a front annular edge 134 complementary to the edge front annular 76 of the half-skirt 62.

L'assemblage du capot 34 sur le corps 32 s'effectue selon une direction transversale T perpendiculaire au plan diamétral de partage des deux demi-jupes 62 et 122.The assembly of the cover 34 on the body 32 is carried out in a transverse direction T perpendicular to the plane diametral division of the two half-skirts 62 and 122.

L'assemblage et la fixation du capot 34 sur le corps 32 s'effectue par emboítement élastique.Assembly and fixing of the cover 34 on the body 32 is done by elastic interlocking.

A cet effet, la demi-jupe 122 se prolonge selon la direction tangentielle par deux pattes d'accrochage avant 136 qui sont déformables élastiquement et transversalement et dont chacune comporte à son extrémité libre un bec d'accrochage 138 qui est prévu pour venir s'emboíter, en position assemblée, derrière une aile latérale complémentaire 140 mais en vis-à-vis dans la demi-jupe 62 au niveau des bords longitudinaux 72.For this purpose, the half-skirt 122 is extended according to the tangential direction by two front hooking legs 136 which are elastically and transversely deformable and each of which has a spout at its free end hook 138 which is intended to come to fit, in assembled position, behind a complementary side wing 140 but opposite in the half-skirt 62 at the level of longitudinal edges 72.

La fixation est complétée par deux fentes longitudinales arrière et diamétralement opposées 142 formées dans la paroi latérale 120, au voisinage de son bord annulaire d'extrémité axiale arrière 144, dans lesquelles sont reçus, en position emboítée, deux becs complémentaires d'accrochage 144 formés en vis-à-vis dans la paroi latérale 64 du tronçon arrière massif 58. Le verrouillage et la fixation sont ainsi assurés sensiblement "aux quatre coins" du capot 34 et du corps 32.The fastening is completed by two longitudinal slots rear and diametrically opposite 142 formed in the wall lateral 120, near its annular end edge rear axial 144, in which are received, in position nested, two complementary hooking spouts 144 formed opposite one another in the side wall 64 of the rear section solid 58. Locking and fixing are thus ensured substantially "at the four corners" of the cover 34 and of the body 32.

Sur sa face cylindrique concave interne 146, la paroi latérale 120 comporte deux doigts transversaux de verrouillage 148 et 150.On its internal concave cylindrical face 146, the wall side 120 has two transverse locking fingers 148 and 150.

Les deux doigts 148 et 150 s'étendent transversalement, c'est-à-dire parallèlement à la direction d'emboítement T, et ils sont situés dans un même transversal qui, en position montée, est aligné avec le plan transversal moyen des crans 92A, 92B, 92C du tronçon arrière 58 du corps 32.The two fingers 148 and 150 extend transversely, that is to say parallel to the direction T, and they are located in the same transverse which, in the mounted position, is aligned with the transverse plane by means of the notches 92A, 92B, 92C of the rear section 58 of the body 32.

Le doigt de blocage 148 s'étend transversalement sur une grande longueur, au-delà du plan diamétral des bords 132, tandis que le doigt de blocage 150 s'étend une très courte longueur.The locking finger 148 extends transversely over a great length, beyond the diametrical plane of the edges 132, while the locking finger 150 extends a very short length.

Le doigt 148 est prévu pour être reçu dans un trou 152 de section complémentaire formé dans le tronçon arrière massif 58 entre les fonds 88C et 88A et donc entre les crans adjacents 92C et 92A.Finger 148 is intended to be received in a hole 152 of additional section formed in the rear section solid 58 between the bottoms 88C and 88A and therefore between the notches adjacent 92C and 92A.

Le trou 152 débouche transversalement vers l'intérieur dans la portion avant 86 du passage central 78 au niveau du fond transversal 112.The hole 152 opens transversely inward in the front portion 86 of the central passage 78 at the level of the transverse bottom 112.

Comme on peut le voir sur la figure 3, le premier doigt transversal de blocage 148 comporte un premier tronçon de grande largeur 154 et un tronçon d'extrémité libre 156 d'épaisseur réduite.As can be seen in Figure 3, the first finger transverse blocking 148 has a first section of wide 154 and a free end section 156 reduced thickness.

La largeur, mesurée selon la direction longitudinale par rapport à l'axe X-X du doigt 148, comme celle du doigt 150, est sensiblement égale à la largeur des trous qui les reçoivent et à la distance qui sépare les faces transversales opposées des crans 92A, 92B et 92C formés dans les glissières adjacentes 90A, 90B, 90C.The width, measured in the longitudinal direction by relative to the X-X axis of finger 148, like that of finger 150, is substantially equal to the width of the holes which receive them and to the distance between the opposite transverse faces of the notches 92A, 92B and 92C formed in the adjacent runners 90A, 90B, 90C.

Le doigt de blocage 150 s'étend sur une longueur transversale réduite et il est reçu dans un trou borgne 158 formé, comme le trou 152, entre les crans adjacents 92A et 92B.The locking finger 150 extends over a length reduced transverse and it is received in a blind hole 158 formed, like hole 152, between adjacent notches 92A and 92B.

Sur sa face concave interne 146, la paroi latérale 120 comporte également deux séries de trois bossages en relief 160A, 160B, 160C qui s'étendent radialement vers l'intérieur. La première série avant est située dans le même plan transversal que les doigts de blocage 148 et 150 et que les fonds 88A, 88B, 88C, en position montée, tandis que la seconde série arrière des bossages 160A, 160B, 160C est située axialement en regard des portions arrières 82A, 82B, 82C des passages périphériques.On its internal concave face 146, the side wall 120 also has two sets of three raised bosses 160A, 160B, 160C which extend radially inward. The first front series is located in the same plane transverse than the locking fingers 148 and 150 and that the funds 88A, 88B, 88C, in the mounted position, while the second rear series of bosses 160A, 160B, 160C is located axially opposite the rear portions 82A, 82B, 82C of the peripheral passages.

On décrira maintenant en détail le contact fixe de démarreur 50A en référence aux figures 13 à 17 et 27.We will now describe in detail the fixed contact of starter 50A with reference to FIGS. 13 to 17 and 27.

Le contact fixe 50A est constitué pour l'essentiel par une plaquette 170A, de forme générale rectangulaire, dont les bords longitudinaux parallèles et opposés 172A sont espacés transversalement d'une distance correspondant à la distance transversale entre les bords longitudinaux en vis-à-vis des glissières 90A.The fixed contact 50A essentially consists of a plate 170A, of generally rectangular shape, the parallel and opposite longitudinal edges 172A are spaced transversely of a distance corresponding to the distance transverse between the longitudinal edges opposite the 90A slides.

L'extrémité avant de la plaquette 170A est une patte de contact fixe 174A rabattue radialement vers l'intérieur à angle droit et dont la face axiale d'extrémité avant 176A constitue la face de contact fixe avec laquelle sont susceptibles de coopérer les becs 46 du curseur 42 tandis que sa face transversale opposée arrière 178A est prévue pour, en position montée, être en appui axial contre la portion en vis-à-vis du plot 102A. The front end of the 170A plate is a lug of fixed contact 174A folded radially inwards at an angle straight and whose axial end face 176A constitutes the fixed contact face with which are likely to cooperate the slats 46 of the cursor 42 while its face opposite rear transverse 178A is provided for, in position mounted, be in axial support against the portion facing the stud 102A.

La partie arrière de la plaquette 170A constitue la cosse 84A de sertissage de la plaquette sur le conducteur électrique associé 51A.The rear part of the 170A plate constitutes the terminal 84A for crimping the wafer on the electrical conductor partner 51A.

Ainsi, de manière avantageuse, la face de contact 176A est une face laminée lors de l'élaboration de la plaquette, avant son pliage, et n'est plus, comme dans le cas de l'état de la technique, une face découpée.Thus, advantageously, the contact face 176A is a laminated face during the development of the wafer, before folding, and is no longer, as in the case of the state of the technique, a cut side.

Sur sa face intérieure 180A, c'est-à-dire sur celle qui, en position montée, est orientée vers le fond 88A du passage périphérique 90A, la plaquette 170A comporte un bossage en relief 182A qui est prévu, lors d'une des phases de l'assemblage, pour être reçu dans la dépression correspondante 94A.On its inner face 180A, that is to say on the one which, in the mounted position, is oriented towards the bottom 88A of the passage peripheral 90A, the wafer 170A has a boss in relief 182A which is planned, during one of the phases of the assembly, to be received in the depression corresponding 94A.

Sur chacun de ses bords longitudinaux 172A, la plaquette comporte deux paires d'ergots latéraux alignés et opposés 184A. La largeur des ergots 184A situés vers l'arrière, c'est-à-dire vers la droite en considérant les figures 13 et 14, est sensiblement égale et légèrement inférieure à la largeur, mesurée selon la direction axiale, des crans opposés 92A.On each of its longitudinal edges 172A, the plate has two pairs of aligned lateral lugs and opposite 184A. The width of the lugs 184A located towards the back, i.e. to the right considering the figures 13 and 14, is substantially equal and slightly less than the width, measured in the axial direction, of the opposite notches 92A.

Dans le cas du contact fixe de démarreur 50A, la largeur des ergots latéraux 184A est égale pour les deux ergots d'une même paire de même que les crans 92A qui ont la même largeur.In the case of the fixed starter contact 50A, the width of the lateral pins 184A is equal for both lugs of the same pair as well as the 92A notches which have the same width.

De même, la distance séparant deux ergots latéraux adjacents situés le long d'un même bord longitudinal 172A est légèrement supérieure à la longueur du tronçon avant de la glissière 90A de manière à permettre l'introduction transversale globale du contact fixe 50A avec son fil conducteur 51A selon la direction d'introduction "I" illustrée sur la figure 15 afin qu'il pénètre dans le passage périphérique correspondant 90A, comme cela est illustré à la figure 16. Likewise, the distance between two lateral pins adjacent along the same longitudinal edge 172A is slightly longer than the length of the front section of the 90A slide so as to allow introduction overall transverse of the fixed contact 50A with its wire conductor 51A in the direction of introduction "I" illustrated on Figure 15 so that it enters the peripheral passage correspondent 90A, as illustrated in FIG. 16.

Dans cette position d'introduction, on a amené la face inférieure 180A en appui contre le fond 88A avec le bossage 182A reçu dans la dépression 94A.In this introductory position, we brought the face lower 180A pressing against the bottom 88A with the boss 182A received in depression 94A.

Les ergots latéraux arrière 184A sont reçus dans les crans 92A et la cosse 84A avec le fil 51A est reçu dans la portion arrière 82A du passage 90A.The rear side pins 184A are received in the notches 92A and the terminal 84A with the wire 51A is received in the rear portion 82A of passage 90A.

L'épaisseur du matériau constitutif de la plaquette est légèrement inférieure à la hauteur des rainures des glissières 90A de manière à permettre le coulissement axial selon la direction C indiquée sur la figure 16, c'est-à-dire de la gauche vers la droite, de manière à amener le contact fixe de démarreur 50A dans sa position montée illustrée sur la figure 17 dans laquelle la face transversale arrière 178A de la patte avant de contact de fixe 174A est en appui contre la face en vis-à-vis du plot 102A terminant ainsi une position axiale précise du contact fixe 50A par rapport au corps 32.The thickness of the material of the wafer is slightly less than the height of the slide grooves 90A so as to allow axial sliding according to the direction C indicated in figure 16, i.e. from the left to the right, so as to bring the fixed contact of starter 50A in its mounted position illustrated in the figure 17 in which the rear transverse face 178A of the tab fixed contact front 174A is pressing against the face in vis-à-vis the stud 102A thus ending an axial position precise of the fixed contact 50A with respect to the body 32.

Dans cette position axiale précise de montage, les encoches 185A, délimitées par les bords transversaux en vis-à-vis 183A des ergots latéraux 184A, sont alignées transversalement avec les crans 92A et les ergots 184A sont effacés axialement sous les glissières 90A empêchant tout échappement radial du contact.In this precise axial mounting position, the notches 185A, delimited by the transverse edges opposite 183A of the lateral lugs 184A, are aligned transversely with notches 92A and lugs 184A are erased axially under the runners 90A preventing all radial contact exhaust.

Au cours du déplacement axial vers sa position montée, en partant de la figure 16 jusqu'à la position illustrée à la figure 17, le bossage 182A quitte la dépression 94A en grimpant sur la rampe 96A pour franchir cette dernière et être reçu transversalement à l'intérieur de la partie arrière 82 du passage 90A axialement en arrière du bord 98A.During the axial movement towards its mounted position, from figure 16 to the position illustrated in Figure 17, the boss 182A leaves the depression 94A in climbing on ramp 96A to cross it and be received transversely inside the rear part 82 of the passage 90A axially behind the edge 98A.

L'agencement du bossage 182A et de la dépression 94A procure ainsi un effet d'emboítement au moment du verrouillage à l'issue du coulissement et un verrouillage en position montée illustré à la figure 17. The arrangement of the boss 182A and the depression 94A thus provides a nesting effect at the time of locking after sliding and locking in mounted position illustrated in figure 17.

La mise en place des deux autres contacts fixes périphériques 50B et 50C dans les passages périphériques 90B et 90C s'effectue de la même manière.The installation of the two other fixed contacts peripherals 50B and 50C in the peripheral passages 90B and 90C are performed in the same way.

On ne décrira pas ici entièrement la structure des contacts fixes 50B et 50C illustrés respectivement aux figures 18 à 20 et 21 à 23 sur lesquelles les mêmes chiffres de référence qu'aux figures 13 à 15 ont été reportées indicées respectivement avec les lettres B et C.We will not fully describe here the structure of fixed contacts 50B and 50C illustrated respectively in the figures 18 to 20 and 21 to 23 on which the same figures of reference that in FIGS. 13 to 15 have been reported indexed respectively with the letters B and C.

Toutefois, pour constituer des moyens de détrompage en coopération avec les formes et les dimensions des crans associés, on note que les ergots latéraux arrière opposés 184B et 184C ont des largeurs, mesurées selon la direction axiale, différentes afin d'empêcher le montage du contact fixe 50B en lieu et place du contact fixe 50C et inversement.However, to constitute means of polarization in cooperation with the shapes and dimensions of the notches associated, we note that the opposite rear lateral lugs 184B and 184C have widths, measured according to the direction axial, different to prevent mounting of the fixed contact 50B in place of the fixed contact 50C and vice versa.

Le montage d'un contact fixe 50B ou 50C à la place du contact fixe 50A est impossible car la largeur transversale séparant les bords longitudinaux 172B et 172C est nettement inférieure à celle séparant les bords longitudinaux 172A du contact fixe 50A.The mounting of a fixed contact 50B or 50C in place of the fixed contact 50A is impossible because the transverse width separating the longitudinal edges 172B and 172C is clearly less than that separating the longitudinal edges 172A from fixed contact 50A.

Enfin, du fait de cette largeur réduite séparant les bords longitudinaux 172A, le contact fixe 50A présente globalement une largeur réduite qui empêche son montage et son verrouillage en position montée en lieu et place de l'un ou l'autre des contacts fixes 50B ou 50C.Finally, because of this reduced width separating the edges longitudinal 172A, the fixed contact 50A has overall a reduced width which prevents its mounting and its locking in the mounted position instead of one or the other of the fixed contacts 50B or 50C.

On décrira maintenant la structure du contact fixe central 48 illustré aux figures 24 à 26.We will now describe the structure of the fixed contact central 48 illustrated in FIGS. 24 to 26.

Comme les contacts fixes périphériques 50A, 50B, 50C, il est essentiellement constitué par une plaquette 170 dont le bord d'extrémité avant, qui fait saillie axialement dans le fond transversal 66, est ici un bord découpé 176, le contact central 48 ne possédant pas de patte de contact rabattue à l'avant de manière à permettre son introduction axiale, de l'arrière vers l'avant, dans son passage central associé 88.Like the fixed peripheral contacts 50A, 50B, 50C, it is essentially constituted by a plate 170 whose front end edge, which projects axially into the bottom transverse 66, here is a cut edge 176, the central contact 48 having no contact tab folded down in front of so as to allow its axial introduction, from the rear towards the front, in its associated central passage 88.

La partie arrière 84 est constituée par la cosse de sertissage.The rear part 84 is formed by the terminal of crimping.

Sur ses bords longitudinaux opposés 172, le contact fixe central comporte deux ergots latéraux arrière 184 qui s'étendent latéralement sur des longueurs différentes de manière à constituer un moyen de détrompage de l'orientation angulaire de la plaquette 170 dans le passage central 78 de manière à être sûr que sa cosse 84 avec son fil 48A puisse bien être introduit axialement dans la portion arrière 82 du passage 78.On its opposite longitudinal edges 172, the contact central fixed has two rear side pins 184 which extend laterally over different lengths of so as to constitute a means of polarization of the orientation angle of the plate 170 in the central passage 78 of so as to be sure that its terminal 84 with its 48A wire can well be introduced axially into the rear portion 82 of the passage 78.

Cette introduction axiale se poursuit jusqu'à ce que les bords transversaux orientés vers l'avant 183 des ergots latéraux 184 viennent en butée contre le fond transversal 112 séparant la partie arrière 82 de la partie avant formant glissière 86 du passage 78.This axial introduction continues until the forward-facing transverse edges 183 of the lugs side 184 abuts against the transverse bottom 112 separating the rear part 82 from the front part forming slide 86 of passage 78.

Comme on peut le voir également aux figures 24 à 26, l'un des bords longitudinaux 172, vers le haut en considérant la figure 24, comporte une encoche 185 délimitée vers l'arrière par le bord transversal avant 183 de l'ergot latéral 184 et vers l'avant par un bord transversal 187 qui comporte une rampe inclinée 190.As can also be seen in Figures 24 to 26, one of the longitudinal edges 172, upwards considering FIG. 24 includes a notch 185 delimited towards the rear by the front transverse edge 183 of the lateral lug 184 and towards the front by a transverse edge 187 which has a ramp tilted 190.

Comme on peut le voir sur les différentes figures illustrant les contacts fixes, ceux-ci peuvent être réalisés en bande étant reliés entre eux par des portions de liaison ou d'attelage 200, illustrées en silhouette aux figures 13, 18, 21 et 24, qui sont rattachées aux contacts dans les fonds des encoches 185, 185A, 185B, 185C et qui, après leur découpage pour la désolidarisation des contacts réalisés en bande, ne laissent donc pas subsister de bavures susceptibles de détériorer les matières plastiques du corps 32 lors de la mise en place des contacts.As can be seen in the different figures illustrating the fixed contacts, these can be made by strip being connected together by connecting portions or coupling 200, illustrated in silhouette in Figures 13, 18, 21 and 24, which are attached to the contacts in the funds of notches 185, 185A, 185B, 185C and which, after their cutting for the separation of the contacts made in strip, do not therefore do not leave any burrs likely to deteriorate the plastics of the body 32 when putting in place of the contacts.

De plus, les zones de raccordement des portions de liaison 200 ne modifient pas la géométrie des bords ou contours les plus importants du point de vue fonctionnel pour la mise en place et le verrouillage des contacts.In addition, the connection areas of the portions of bond 200 do not change the geometry of the edges or the most functionally important contours for setting up and locking the contacts.

Une fois que tous les contacts fixes sont en position montée dans le corps, et que les autres composants de l'interrupteur 30 sont en position d'assemblage, l'opération finale consiste à assembler le capot 34 sur le corps en l'introduisant axialement selon la direction T.Once all of the stationary contacts are in position rise in the body, and that the other components of the switch 30 are in the assembly position, the operation final consists in assembling the cover 34 on the body in introducing it axially in the direction T.

Lors de cette introduction, les doigts transversaux de blocage 148 et 150 pénètrent respectivement dans les trous 152 et 158.During this introduction, the transverse fingers of blocking 148 and 150 respectively enter the holes 152 and 158.

Le tronçon d'extrémité libre 156 des doigts de blocage 148 de grande longueur est reçu dans l'encoche 185 du contact fixe central 48 pour immobiliser axialement par rapport au corps 32.The free end section 156 of the locking fingers 148 of great length is received in notch 185 of the central fixed contact 48 for immobilizing axially relative to to the body 32.

Au cours de sa pénétration, le tronçon 156 coopère avec la rampe 190 formée dans le bord 187 de l'encoche 185 pour plaquer le contact central 48 en position de butée axiale de manière que son extrémité libre de contact 176 occupe une position précise par rapport au fond transversal 66.During its penetration, the section 156 cooperates with the ramp 190 formed in the edge 187 of the notch 185 to press the central contact 48 in the axial stop position so that its free contact end 176 occupies a precise position in relation to the transverse bottom 66.

Le tronçon formant pied 154 de plus grande largeur du doigt transversal 148 est reçu simultanément dans les crans adjacents 92A et 92C et dans les encoches en vis-à-vis 185A et 185C de manière à immobiliser axialement les contacts fixes périphériques 50A et 50C.The section forming a foot 154 of greater width of the transverse finger 148 is received simultaneously in the notches adjacent 92A and 92C and in the notches opposite 185A and 185C so as to immobilize the fixed contacts axially peripherals 50A and 50C.

De la même manière, le doigt transversal de blocage 150 de longueur réduite est reçu dans le trou borgne 158 et simultanément dans les crans adjacents 92A et 92B et dans les encoches en vis-à-vis 185A et 185B de manière à immobiliser axialement le contact fixe 50A et le contact fixe 50B par rapport au corps 32 dans la position montée dans laquelle ils ont été préalablement verrouillés et dans laquelle ils occupent, comme le contact fixe 50C, une position précise par rapport à l'intérieur de la chambre de contact 58 en appui sur les plots 102A, 102B et 102C.In the same way, the transverse locking finger 150 of reduced length is received in blind hole 158 and simultaneously in the adjacent notches 92A and 92B and in the notches opposite 185A and 185B so as to axially immobilize the fixed contact 50A and the fixed contact 50B relative to the body 32 in the position mounted in which they were previously locked in and in which like the fixed contact 50C, they occupy a precise position with respect to the interior of the contact chamber 58 bearing on pads 102A, 102B and 102C.

En fin du mouvement transversal du capot 34 sur le corps 32 se produit le verrouillage en position emboítée grâce aux moyens de verrouillage décrits précédemment.At the end of the transverse movement of the cover 34 on the body 32 occurs locking in the nested position thanks to the locking means described above.

En position emboítée et verrouillée, les deux séries de bossage 160A, 160B, 160C viennent plaquer radialement vers l'intérieur les plaquettes 170A, 170B et 170C contre les fonds 88A, 88B et 88C, c'est-à-dire qu'ils les maintiennent en position radiale et axiale par rapport au boítier 132.In the nested and locked position, the two series of boss 160A, 160B, 160C press radially towards inside the plates 170A, 170B and 170C against the bottoms 88A, 88B and 88C, that is, they keep them in radial and axial position relative to the housing 132.

Comme on peut le voir sur la figure 27, les trois contacts fixes périphériques constitués par les trois pattes de contact rabattues 174A, 174B et 174C s'étendent toutes dans un même plan transversal.As can be seen in Figure 27, the three fixed peripheral contacts formed by the three tabs folded contacts 174A, 174B and 174C all extend in the same transverse plane.

La position angulaire de repos du curseur 42 est parfaitement déterminée car ses becs 132 sont reçus simultanément dans les deux crans adjacents 108.The angular position of rest of the cursor 42 is perfectly determined because its beaks 132 are received simultaneously in the two adjacent notches 108.

La partie centrale 49 du curseur 42 est quant à elle maintenue en contact contre le contact fixe central 48 par l'intermédiaire du ressort conique 43 (voir figure 1).The central part 49 of the cursor 42 is itself maintained in contact against the central fixed contact 48 by through the conical spring 43 (see Figure 1).
