Abstract

The switch comprises a cylindrical box (32,34) which includes a solid rear section (58). This rear section includes a central passage (78) and peripheral passages (80A,80B,80C) arranged near to the edges of the solid section. Each of these peripheral passages holds a fixed contact (50A,50B,50C). A fixed central contact (48) is connected to the three contacts (50A,50B,50C) respectively connected to a starter supply circuit, an ignition coil and an electrical accessory supply circuit. The box surrounding the switch is formed from two parts, the first of which (32) lies beneath the solid contact carrying section. The second of these parts (34) comprises a half-cylindrical section which fits over and around the solid section. These two sections fit together elastically to enclose the contact space.

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 rotary electrical switch with multiple positions, in particular 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 which can be operated using the ignition key at the option of the user and which, depending on the angular orientation of the key, establishes various electrical circuits necessary for starting and operating the vehicle, as well as than when it stopped.

L'invention est relative à un interrupteur du type comportant un boîtier 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 boîtier, 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 generally cylindrical housing 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, depending on 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 boîtier 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 boîtier 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 housing is a solid part which has the various passages for fixed contacts and with which is associated a cover which is attached to one of the axial ends of the solid housing and whose skirt-shaped side wall delimits the contact chamber in which the rotor is mounted.

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 boîtier 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 the various components particularly complex and in particular does not allow its automation as complete as possible. In addition, once the fixed contacts and the movable contact in place and after fitting the cover, the lateral cylindrical wall of the housing remains an incomplete wall and the component constituted by the switch needs to be installed in a complementary envelope, c '' It is to say that it does not constitute a complete and autonomous component which can be implanted with the greatest possible freedom in association with an anti-theft device.

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 design, all the passages which receive the fixed contacts are produced 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 front end cut and of rounded profile which projects axially in the bottom of the contact chamber to constitute the fixed contact surface with which the movable contact cooperates.

Une telle conception présente de nombreux inconvénients.Such a design has many drawbacks.

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 zone is constituted by a rounded cut edge and the surface condition of this fixed contact zone with which a contact zone formed in facing contact on the rotary movable contact cooperates by friction. electrically satisfactory and causes premature wear of the 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 maîtriser de manière précise la position axiale du contact fixe par rapport au boîtier 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 blocking in the mounted position by a transverse cover locking finger do not allow precise control of the axial position of the fixed contact relative to the housing and therefore the position of the fixed contact zone end 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 insofar as it is ensured by the cooperation of the locking finger with two opposite abutment surfaces formed in a longitudinal edge of the fixed contact in the form of a wafer constituted by the lateral edges 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 associated locking finger.

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 cover locking fingers have ramps which, during the transverse insertion movement of the locking fingers, are worn by friction against the edges of the locking locking notch. the corresponding fixed contact plate.

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 introduction 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 solid body of insulating plastic material and lead to the formation of plastic chips which are introduced into the contact chamber and which can prevent the switch from functioning properly later.

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 design according to the state of the art also does not ensure a polarization between the different fixed contacts, and in particular the peripheral contacts and it sometimes results in an incorrect mounting of the fixed contacts leading to a manufacturing defect in the light 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 a cursor, is sometimes insufficient, in particular for the determination of some of its angular positions relative to the 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 boîtier complet et permettant un montage simplifié des contacts fixes.The object of the present invention is to propose a new design of an electric switch of the type mentioned above which overcomes these drawbacks, and which in particular makes it possible to produce a switch with complete housing and allowing simplified mounting of the 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, of axis X-X, with multiple positions.

Il est constitué pour l'essentiel par un boîtier en deux parties 32 et 34, par un rotor 36 et par une platine 38.It essentially consists of a two-part housing 32 and 34, a rotor 36 and 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 comprises a housing 40 which receives a rotary movable contact 42, called a cursor, in the general shape of a V with two branches 44 and 46 which is designed to establish, as a function of the angular position of the rotor 36, different electrical contacts between a central fixed contact 48 which, as will be explained below, is always in contact with the central part 49 of the movable contact 42 and three fixed peripheral 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 vehicle battery fitted with the anti-theft device, the peripheral contact 50A is connected to the starter supply circuit, the contact 50B is connected to the coil and the peripheral contact 50C is connected to the vehicle's electrical accessories supply circuit.

Selon une conception connue, le rotor 36 assure également l'entraînement 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 also ensures the rotational drive of a contact plate 52 received in a housing 54 of the rotor 36 and which establishes electrical contact between two diametrically opposite fixed terminals 56 carried by the plate 38 and which are connected to the ignition circuit of the vehicle engine.

Les deux parties 32 et 34 du boîtier 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 the plate 38 are made of electrically insulating material, for example by plastic molding.

Conformément aux enseignements de l'invention, la première partie 32 du boîtier 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 plastic molded part 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 side wall 64 of generally convex semi-cylindrical shape and by a transverse bottom 66 which extends in a diametral plane and 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 front section 60 partially define a contact chamber 68 which is axially open and in which the rotor 36 is mounted for rotation with the rotary slider 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 substantially planar outer wall 70 which extends substantially in the axial plane passing through the longitudinal end edges 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 solid rear section 58 is also delimited by a rear transverse face with an axial end 74 perpendicular to the axis X-X 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 with an 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 solid rear section 58 has a central passage 78 of axial orientation which opens at its front and rear axial ends 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 front, that is to say from right to left considering FIG. 5, the fixed contact central 48 with its 48A electrical connection wire.

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 includes three peripheral passages 80A, 80B and 80C each of which is intended to receive respectively the fixed peripheral 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.According to a characteristic of the invention, each peripheral passage is open radially outwards in the convex cylindrical lateral face 64 of the solid 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 comprises a rear portion of generally concave semi-cylindrical shape 82A, 82B, 82C which is intended to receive the corresponding electrical conductor 51A, 51B, 51C and the rear crimping 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 peripheral passage is produced in the form of a slide of rectangular section open radially outwards 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 the passage 80A is less than the transverse width of the front portions 86B, 86C of the 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 longitudinal width, that is to say measured parallel to the axis XX, and they open transversely into 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, as will be explained below, polarizing 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 front portions of the 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 bottoms comprises a depression 94A, 94B, 94C arranged axially opposite the corresponding notches and which ends axially towards the rear by 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.The ramps 96A, 96B, 96C end in the vicinity of the rear transverse edge 98A, 98B, 98C of the 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 an annular edge 100 which has three raised contact pads 102A, 102B, 102C aligned axially respectively with the three peripheral passages and 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 of a semi-cylindrical ring 104 whose front axial end edge 106 has two adjacent stop notches 108 with ramps 110 , the angular difference between the two notches corresponding to the difference 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 comprises a rear portion of generally semi-cylindrical shape 82 intended to receive the terminal 84 of the central fixed contact 48 and its associated electrical conductor 48A.

Il 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 rectangular section which extend laterally over different lengths, relative to the axis X-X, as can be seen in FIG. 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 towards the front by a transverse bottom 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 opposite 114 intended to receive the lugs 116 of the fixed ignition contacts 56 with their associated conducting wires 118.

On décrira maintenant en détail le capot 34 illustré notamment aux figures 3 et 8 à 12.The cover 34 will now be described in detail, illustrated in particular in FIGS. 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 rear semi-cylindrical side wall 120 which, in the assembled position of the cover 34 on the body 32, is provided to 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 chamber 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 with respect to the side wall 120 is provided to come opposite 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 boîtier.The half-skirt 122 comprises a window 126 which, in the assembled position, is diametrically opposite to a symmetrical window 127 formed in the half-skirt 62, these two windows being provided to receive the opposite diametrical tabs 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 has two raised ramps 130 which are designed to cooperate with the spouts 133 of the arms 44 and 46 of the cursor 42 to control the movements of the latter 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 opposite longitudinal edges 132 which, in the assembled position, are opposite 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 defined axially by a front annular edge 134 complementary to the front annular edge 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 takes place in a transverse direction T perpendicular to the diametral plane of sharing of the two half-skirts 62 and 122.

L'assemblage et la fixation du capot 34 sur le corps 32 s'effectue par emboîtement élastique.The assembly and fixing of the cover 34 on the body 32 is carried out 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'emboîter, 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.To this end, the half-skirt 122 is extended in the tangential direction by two front hooking lugs 136 which are elastically and transversely deformable and each of which comprises at its free end a hooking spout 138 which is intended to come s' fitting, in the assembled position, behind a complementary lateral wing 140 but vis-à-vis in the half-skirt 62 at the 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 emboîtée, 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 fixing is completed by two rear longitudinal and diametrically opposite slots 142 formed in the side wall 120, in the vicinity of its annular edge of rear axial end 144, in which are received, in position nested, two complementary hooking spouts 144 formed opposite each other in the side wall 64 of the solid rear section 58. The locking and the 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 side wall 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'emboîtement 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 interlocking direction T, and they are located in the same transverse which, in the mounted position, is aligned with the mean transverse plane 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.The finger 148 is intended to be received in a hole 152 of complementary section formed in the solid rear section 58 between the bottoms 88C and 88A and therefore between the adjacent notches 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 inwards into 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 FIG. 3, the first transverse locking finger 148 comprises a first very wide section 154 and a free end section 156 of 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 relative to the axis XX of the finger 148, like that of the finger 150, is substantially equal to the width of the holes which receive them and to the distance which separates the opposite transverse faces of the notches 92A, 92B and 92C formed in the adjacent slides 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 reduced transverse length and it is received in a blind hole 158 formed, like the hole 152, between the 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 comprises two series of three raised bosses 160A, 160B, 160C which extend radially inwards. The first front series is located in the same transverse plane as the locking fingers 148 and 150 and that the bottoms 88A, 88B, 88C, in the mounted position, while the second rear series of the bosses 160A, 160B, 160C is located axially in look of 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.The fixed starter contact 50A will now be described in detail 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, whose parallel and opposite longitudinal edges 172A are spaced transversely by a distance corresponding to the transverse distance between the longitudinal edges opposite 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 wafer 170A is a fixed contact tab 174A folded radially inwards at a right angle and whose axial front end face 176A constitutes the fixed contact face with which the spouts 46 of the slider 42 while its opposite rear transverse face 178A is provided for, in the mounted position, to bear axially against the portion opposite 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 plate 170A constitutes the terminal 84A for crimping the plate onto the associated electrical conductor 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 preparation of the wafer, before it is folded, and is no longer, as in the case of the state of the art, a cut face.

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 that which, in the mounted position, is oriented towards the bottom 88A of the peripheral passage 90A, the plate 170A has a raised boss 182A which is provided, during one of the assembly phases, to be received in the corresponding depression 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 and opposite lateral lugs 184A. The width of the lugs 184A situated towards the rear, that is to say towards the right when considering FIGS. 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 the two pins of the same pair, as are the notches 92A 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.Similarly, the distance separating two adjacent lateral pins situated along the same longitudinal edge 172A is slightly greater than the length of the front section of the slide 90A so as to allow the overall transverse introduction of the fixed contact 50A with its conducting wire 51A in the direction of introduction "I" illustrated in FIG. 15 so that it enters the corresponding peripheral passage 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 insertion position, the lower face 180A has been brought to bear against the bottom 88A with the boss 182A received in the 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 lateral pins 184A are received in the notches 92A and the terminal 84A with the wire 51A is received in the rear portion 82A of the 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 grooves of the slides 90A so as to allow axial sliding in the direction C indicated in Figure 16, that is to say from left to right , so as to bring the fixed starter contact 50A into its mounted position illustrated in FIG. 17 in which the rear transverse face 178A of the fixed contact front tab 174A is in abutment against the face opposite the stud 102A thus terminating a precise axial position of the fixed contact 50A relative 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 the notches 92A and the lugs 184A are axially erased under the slides 90A preventing any escape contact radial.

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 displacement towards its mounted position, starting from FIG. 16 to the position illustrated in FIG. 17, the boss 182A leaves the depression 94A by climbing on the ramp 96A to cross the latter and be received transversely to the 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'emboîtement 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 an interlocking effect at the time of locking after sliding and a locking in the mounted position illustrated in FIG. 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 two other fixed peripheral contacts 50B and 50C are placed in the peripheral passages 90B and 90C 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 the fixed contacts 50B and 50C illustrated respectively in FIGS. 18 to 20 and 21 to 23 on which the same reference numerals as in FIGS. 13 to 15 have been given 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 polarizing means in cooperation with the shapes and dimensions of the associated notches, it is noted that the opposite rear lateral pins 184B and 184C have different widths, measured in the axial direction, in order to prevent the mounting of the contact. fixed 50B instead 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 much smaller than that separating the longitudinal edges 172A from the 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, due to this reduced width separating the longitudinal edges 172A, the fixed contact 50A generally has a reduced width which prevents it from being mounted and locked in the assembled position in place of one or 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 central fixed contact 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 in the transverse bottom 66, is here a cut edge 176, the central contact 48 not having no contact tab folded down in front of so as to allow its axial introduction, from the rear towards the front, into its associated central passage 88.

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

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 central fixed contact comprises two rear lateral lugs 184 which extend laterally over different lengths so as to constitute a means for polarizing the angular orientation of the wafer 170 in the central passage 78 to be sure that its terminal 84 with its wire 48A can indeed 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 transverse edges oriented towards the front 183 of the lateral pins 184 abut against the transverse bottom 112 separating the rear part 82 from the front part forming a slide 86 of the 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 FIGS. 24 to 26, one of the longitudinal edges 172, upwards when considering FIG. 24, has a notch 185 delimited towards the rear by the front transverse edge 183 of the lateral lug 184 and forwards by a transverse edge 187 which comprises an inclined ramp 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 various figures illustrating the fixed contacts, these can be produced in a strip being connected together by connecting or coupling portions 200, illustrated in silhouette in FIGS. 13, 18, 21 and 24, which are attached to the contacts in the bottoms of the notches 185, 185A, 185B, 185C and which, after their cutting for the separation of the contacts made in strip, therefore do not leave any burrs likely to remain deteriorate the plastics of the body 32 when the contacts are put in place.

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 connecting portions 200 do not modify the geometry of the edges or contours that are most important from the functional point of view for the positioning and locking of 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 the fixed contacts are in the mounted position in the body, and the other components of the switch 30 are in the assembly position, the final operation consists in assembling the cover 34 on the body by introducing it axially. according to 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 locking fingers 148 and 150 penetrate respectively into 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 long locking fingers 148 is received in the notch 185 of the central fixed contact 48 to immobilize axially relative 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 with respect to at 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 the foot 154 of greater width of the transverse finger 148 is received simultaneously in the adjacent notches 92A and 92C and in the facing notches 185A and 185C so as to immobilize the peripheral fixed contacts 50A and 50C axially.
