Description

La présente invention concerne un bloc de contacts tripolaire, notamment à rupture brusque et à ouverture positive, utilisable dans un interrupteur sensible à un mouvement de poussée, particulièrement un interrupteur de position, bouton-poussoir ou organe analogue.The present invention relates to a three-pole contact block, in particular breaking abrupt and positive opening, usable in a movement sensitive switch push button, especially a position switch, push button or the like.

De tels blocs comprennent habituellement un boítier qui loge des pièces fixes de contact terminées à une extrémité par des plages de connexion et portant à une autre extrémité un contact fixe, ainsi qu'un équipage mobile muni de plusieurs ponts de contact de manière à ménager avec les contacts fixes au moins un pôle à ouverture et un pôle à fermeture. L'équipage mobile est sollicité d'une part par un poussoir, d'autre part par un système de ressort, le tout étant agencé pour produire une ouverture positive et une ouverture et une fermeture brusques.Such blocks usually include a housing which houses fixed parts of contact terminated at one end by connection pads and bringing to a other end a fixed contact, as well as a mobile equipment provided with several bridges contact so as to provide at least one pole with opening with the fixed contacts and a pole with closure. The moving team is requested on the one hand by a pusher, on the other hand by a spring system, the whole being arranged to produce a positive opening and a sudden opening and closing.

On sait mettre en oeuvre dans un interrupteur multipolaire un bloc de contacts doté d'un poussoir qui sollicite un porte-contacts à plusieurs ponts superposés, les ponts étant montés de façon réversible pour assurer une fonction "normalement ouvert" (NO) ou "normalement fermé" (NC) au pôle correspondant.We know how to implement a contact block with a multi-pole switch a pushbutton which requests a contact carrier with several superimposed bridges, the bridges being reversibly mounted to provide a "normally open" function (NO) or "normally closed" (NC) at the corresponding pole.

Il est dans certains cas souhaitable de conférer à l'un des pôles d'un interrupteur tripolaire une fonction NO ou NC sans avoir à modifier le porte-contacts.In some cases it is desirable to give one of the poles of a switch three-pole NO or NC function without having to modify the contact carrier.

L'invention a pour but de permettre à un bloc de contacts multipolaire de fonctionner avec au moins un pôle commutable de l'état normalement ouvert à l'état normalement fermé ou inversement, sans modification de l'agencement du porte-contacts.The object of the invention is to allow a multipolar contact block to operate. with at least one switchable pole from the normally open state to the normally state closed or vice versa, without changing the arrangement of the contact carrier.

Selon l'invention, les plages de connexion sont disposées selon au moins trois plans de connexion distincts, et l'équipage mobile présente au moins trois ponts de contact répartis de manière à coopérer avec des contacts fixes situés dans deux plans transversaux de contact et à se déplacer dans deux plans frontaux ; deux ponts de contact qui sont situés dans le premier plan frontal coopèrent avec des pièces fixes de contact sortant sur deux plans de connexion, et le troisième pont de contact qui est situé dans le deuxième plan frontal coopère avec les pièces fixes de contact sortant sur le troisième plan de connexion. Le troisième plan de connexion est notamment situé en position médiane entre les deux premiers plans de connexion.According to the invention, the connection pads are arranged in at least three separate connection plans, and the moving part has at least three bridges contact distributed so as to cooperate with fixed contacts located in two transverse planes of contact and to move in two frontal planes; of them contact bridges which are located in the foreground foreground cooperate with fixed outgoing contact parts on two connection planes, and the third bridge contact which is located in the second frontal plane cooperates with the fixed parts of outgoing contact on the third connection plane. The third connection plan is notably located in the middle position between the first two connection planes.

Le bloc de contacts est de préférence tripolaire et l'équipage mobile présente alors quatre ponts de contact à disposition symétrique équilibrée, le quatrième pont de contact étant situé dans le deuxième plan frontal et ne coopérant pas avec les pièces de contact fixe.The contact block is preferably three-pole and the moving assembly then presents four symmetrically balanced contact bridges, the fourth bridge contact being located in the second frontal plane and not cooperating with the parts fixed contact.

L'équipage mobile peut présenter en substitution au quatrième pont de contact une pièce d'appui élastique ou mobile située dans le deuxième plan frontal en regard du troisième pont de contact situé dans ce plan, pour se déplacer en même temps que le pont de contact situé dans le même plan transversal.The moving part may present in substitution for the fourth contact bridge a elastic or movable support piece located in the second frontal plane facing the third contact bridge located in this plane, to move at the same time as the contact bridge located in the same transverse plane.

Il est avantageux que les ponts de contact situés à des niveaux différents dans un même plan frontal soient sollicités par un ressort de compression unique tendant à les écarter l'un de l'autre.It is advantageous that the contact bridges located at different levels in a same frontal plane are stressed by a single compression spring tending to separate them from each other.

Dans un mode de réalisation à montage simplifié, l'équipage mobile est monté dans le boítier par introduction via une face arrière ouverte du boítier et un fond est assemblé, notamment encliqueté, au boítier pour recouvrir la face arrière. Le fond peut alors présenter des pattes ou éléments analogues de maintien qui prennent appui contre les pièces fixes de contact aboutissant au plan arrière pour contribuer à les maintenir de manière très simple. Un capot d'isolement des bornes peut être rapporté, notamment encliqueté, sur la face avant du boítier. In a simplified assembly embodiment, the mobile assembly is mounted in the case by introduction via an open rear face of the case and a bottom is assembled, in particular snapped into place, to cover the rear face. The bottom may then have legs or similar holding elements which take support against fixed contact parts leading to the rear plane to contribute to keep them very simple. A terminal isolation cover can be reported, including snapped, on the front of the housing.

    • Le bloc de contacts tripolaire représenté sur les figures comprend un boítier 10 en matière isolante qui loge six pièces conductrices 11,12,13,14,15,16 portant des contacts fixes et un équipage mobile 17 à ouverture positive et mouvements brusques d'ouverture et de fermeture, l'équipage étant guidé dans ce boítier et doté de contacts mobiles qui coopèrent avec les contacts fixes.The three-pole contact block shown in the figures comprises a housing 10 in insulating material which houses six conductive parts 11,12,13,14,15,16 carrying fixed contacts and a moving element 17 with positive opening and sudden movements opening and closing, the crew being guided in this box and equipped with movable contacts which cooperate with the fixed contacts.

    Le boítier 10 est de forme quadrangulaire et présente vers l'avant trois groupes de deux bornes 21,22,23,24,25,26 réparties sur trois plans de connexion respectifs P1,P2,P3. Chaque borne 21-26 comporte une vis 27 de serrage de câble (ou une pièce de serrage élastique) coopérant avec une plage de connexion 28 de la pièce conductrice 11-16 correspondante. Les pièces conductrices 11,12 et 15,16 associées aux bornes 21,22 et 25,26 situées dans les plans de connexion extrêmes P1,P3 sont de préférence identiques entre elles ; les pièces conductrices 13,14 associées aux bornes médianes 23,24 du plan médian P2 diffèrent des autres pièces conductrices et sont de préférence identiques entre elles (voir figure 6).The housing 10 is of quadrangular shape and presents forward three groups of two terminals 21,22,23,24,25,26 distributed on three respective connection planes P1, P2, P3. Each terminal 21-26 has a cable clamping screw 27 (or a elastic clamping piece) cooperating with a connection pad 28 of the piece corresponding driver 11-16. The associated conductive parts 11, 12 and 15, 16 at terminals 21,22 and 25,26 located in the extreme connection planes P1, P3 are preferably identical to each other; the conductive parts 13.14 associated with the median terminals 23.24 of the median plane P2 differ from the other parts conductive and are preferably identical to each other (see Figure 6).

    A leur extrémité opposée à la plage de connexion 28, les pièces 11-16 se terminent par un contact fixe 29 sous forme de pastille ; les pastilles de contact 29 des pièces 11,12,15,16 sont situées dans un plan frontal arrière PR (parallèle au fond et à la face avant du bloc et perpendiculaire aux plans P1-P3) et celles des pièces 13,14 sont situées dans un plan frontal avant PF parallèle à PR. En hauteur, les pastilles 29 des pièces 11,12 sont situées dans un plan P4 intermédiaire entre P1 et P2 et celles des pièces 15,16 sont situées dans un plan P5 intermédiaire entre P2 et P3 ; les pastilles des pièces 13,14 sont situées dans le plan P4 ou P5 selon la configuration choisie pour le bloc, comme il sera expliqué plus loin.At their end opposite to the connection pad 28, the parts 11-16 end by a fixed contact 29 in the form of a pellet; contact pads 29 of the parts 11,12,15,16 are located in a rear frontal plane PR (parallel to the bottom and to the front face of the block and perpendicular to planes P1-P3) and those of parts 13,14 are located in a front plane PF parallel to PR. In height, the pellets 29 of the parts 11, 12 are located in a plane P4 intermediate between P1 and P2 and those of parts 15, 16 are located in a plane P5 intermediate between P2 and P3; the pads of the parts 13,14 are located in the plane P4 or P5 depending on the configuration chosen for the block, as will be explained later.

    Le boítier 10 du bloc offre une patte de fixation 18, par exemple pour être logé dans un corps d'interrupteur de position. Le boítier 10 est recouvert à l'avant par un capot encliquetable 30 qui assure une fonction de protection et d'imperdabilité des vis de bornes. Le capot 30 présente une paroi 31 formant la face avant du bloc tout en dégageant un accès aux vis, ainsi que des cloisons d'isolement inter-bornes 32 et des crans latéraux d'encliquetage sur les bords avant du bloc. Le boítier 10 présente à l'arrière une face ouverte 33 qui permet l'introduction du bloc de contacts et qui est fermée par un fond encliquetable 34. Le fond 34 présente une paroi plane dotée, vers l'intérieur du bloc, de pattes 35 qui assurent un maintien des pièces arrière de contact fixe 11,12,13,14. Au lieu de pattes, on peut prévoir des épaulements d'ou autres formes analogues de maintien. Le fond 34 comprend aussi des pattes d'encliquetage 36 sur le boítier.The housing 10 of the block offers a fixing lug 18, for example to be housed in a position switch body. The housing 10 is covered at the front by a cover snap-on 30 which provides a protective and waterproofing function for the terminals. The cover 30 has a wall 31 forming the front face of the block while providing access to the screws, as well as inter-terminal isolation partitions 32 and lateral detent notches on the front edges of the block. Case 10 presents at the rear an open face 33 which allows the introduction of the contact block and which is closed by a snap-on bottom 34. The bottom 34 has a flat wall provided, towards the inside of the block, with lugs 35 which hold the parts fixed rear contact 11,12,13,14. Instead of legs, one can provide shoulders or other similar forms of maintenance. The bottom 34 also includes snap tabs 36 on the housing.

    L'équipage mobile 17 est propre à engendrer une ouverture positive des contacts. Il comporte un poussoir 40 déplaçable selon une direction Z parallèle aux plans PF,PR et sollicité par un ressort de rappel 41, ainsi qu'un porte-contacts 42 à mouvement brusque également mobile selon Z. Le porte-contacts 42 est monté mobile en va-et-vient sur le poussoir et est sollicité par une pièce de renvoi 43. Cette pièce de renvoi traduit, au moyen de leviers d'inversion de mouvement, un mouvement descendant du poussoir en mouvement montant du porte-contacts. Le mouvement montant du porte-contacts 42 est rendu brusque à l'aide de deux ressorts latéraux 44 à passage de point mort. Le mécanisme décrit est connu et n'est pas l'objet de l'invention.The moving element 17 is capable of generating a positive opening of the contacts. he comprises a pusher 40 movable in a direction Z parallel to the planes PF, PR and biased by a return spring 41, as well as a contact carrier 42 with movement abrupt also movable along Z. The contact carrier 42 is mounted movable back and forth on the pusher and is biased by a return piece 43. This piece of reference translates, by means of inversion of movement levers, a movement descending from the moving pusher rising from the contact carrier. Movement amount of contact carrier 42 is made abrupt using two lateral springs 44 at neutral. The mechanism described is known and is not the subject of the invention.

    Quatre ponts de contact 45,46,47,48 sont disposés de manière symétrique et équilibrée sur ou dans le porte-contacts 42 de manière à pouvoir se déplacer par rapport à celui-ci selon Z. Les plans de symétrie des ponts sont confondus avec les plans frontaux PF et PR. Les ponts 45,46 sont situés dans le plan PR et les ponts 47,48 dans le plan PF ; les ponts 45,47 d'une part, et les ponts 46,48 d'autre part, sont situés dans deux plans distincts parallèles à P1-P3, de manière à pouvoir coopérer respectivement avec les pièces 11,12 (pont 45), 15,16 (pont 46), 13,14 (pont 47 ou pont 48 selon le montage adopté pour les pièces 13,14). Chaque pont est doté en son milieu d'une partie isolante surmoulée 49 qui facilite son guidage dans le porte-contacts. Entre les ponts 45,46 d'une part, et les ponts 47,48 d'autre part, on prévoit un ressort de compression 50 qui est en appui direct sur les ponts et tend à les écarter l'un de l'autre pour assurer un rattrapage de jeu et une bonne pression de contact, principalement au moment du basculement. En variante, on peut prévoir à la place de l'un des ponts avant 47,48 une pièce d'appui élastique ou mobile 51 (voir figure 4), par exemple une lame élastique, capable de simuler, quand l'équipage mobile 17 est actionné, le mouvement d'écrasement du pont auquel il est substitué et de suivre le mouvement du pont arrière situé au même niveau.Four contact bridges 45,46,47,48 are symmetrically balanced on or in the contact carrier 42 so as to be able to move relative to this one according to Z. The planes of symmetry of the bridges are confused with the PF and PR frontal plans. The bridges 45,46 are located in the PR plane and the bridges 47.48 in the FP plan; 45.47 bridges on the one hand, and 46.48 bridges on the other hand, are located in two separate planes parallel to P1-P3, so that they can cooperate respectively with parts 11,12 (bridge 45), 15,16 (bridge 46), 13,14 (bridge 47 or bridge 48 depending on the assembly adopted for parts 13,14). Each bridge is provided in the middle with an overmolded insulating part 49 which facilitates its guiding in the contact carrier. Between the bridges 45,46 on the one hand, and the bridges 47,48 on the other hand, a compression spring 50 is provided which bears directly on the bridges and tends to move them apart from each other to ensure a backlash and good pressure contact, mainly at the time of the changeover. Alternatively, one can provide in place of one of the front axles 47,48 an elastic or movable support piece 51 (see Figure 4), for example an elastic blade, capable of simulating, when the crew mobile 17 is activated, the crushing movement of the bridge to which it is substituted and follow the movement of the rear axle located on the same level.

    Les ponts 45,47 forment avec les contacts fixes correspondants des pôles normalement ouverts (NO) et les ponts 46,48 forment avec les contacts fixes correspondants des pôles normalement fermés (NC).The bridges 45,47 form with the corresponding fixed contacts of the poles normally open (NO) and the bridges 46,48 form with the corresponding fixed contacts normally closed poles (NC).

    Le bloc décrit se monte de la façon suivante. Les pièces de contacts fixes sont disposées dans le boítier 10, puis l'équipage mobile est inséré par l'arrière dans le boítier et le fond 34 est encliqueté sur le boítier. Les deux possibilités de configuration du bloc sont illustrées sur les figures 3 et 4. Dans la version de la figure 3, les pièces de contact fixe 13,14 sont disposées avec leurs pastilles de contact dans le plan P4 pour former un pôle NO. Dans la version de la figure 4, les pièces 13,14 sont disposées avec leurs pastilles de contact dans le plan P5 pour former un pôle NC. De plus, on a remplacé dans la version de la figure 4 le pont 47 par ue pièce élastique d'appui pour le ressort 50. Les pièces 13,14 de la version NO peuvent être identiques aux pièces 13,14 de la version NC, de sorte qu'on passe d'une version à l'autre par simple retournement, ou elles peuvent être différentes. De même, le boítier 10 propre à la version NO-NO-NC du bloc de contacts peut être identique au boítier propre à la version NO-NC-NC du bloc ou être différent.The described block mounts as follows. The fixed contact parts are arranged in the housing 10, then the mobile assembly is inserted from the rear into the housing and the bottom 34 is snapped onto the housing. The two configuration possibilities of the block are illustrated in FIGS. 3 and 4. In the version of FIG. 3, the parts 13,14 fixed contact plates are arranged with their contact pads in the plan P4 to form a NO pole. In the version of Figure 4, the parts 13,14 are arranged with their contact pads in the P5 plane to form a pole NC. In addition, in version 4, bridge 47 has been replaced by a part. elastic support for spring 50.
