Description

La présente invention concerne d'une manière générale un dispositif de connexion électrique et plus particulièrement un bloc auxiliaire destiné à être monté sur un contacteur pour assurer soit l'ouverture, soit la fermeture, d'un circuit auxiliaire, en fonction de la positon du coulisseau dudit contacteur.The present invention relates generally to a device for electrical connection and more particularly an auxiliary block intended for be mounted on a contactor to ensure either opening or closure of an auxiliary circuit, depending on the position of the slide of said contactor.

De tels blocs auxiliaires sont connus et usuellement mis en oeuvre sous forme de boítiers renfermant deux bornes reliées au circuit auxiliaire et un pont déplacé par le coulisseau du contacteur entre une position pour laquelle il est en appui contre les deux bornes et les relie électriquement pour fermer le circuit auxiliaire et une position pour laquelle il est éloigné desdites bornes pour ouvrir le circuit auxiliaire.Such auxiliary blocks are known and usually used under form of housings containing two terminals connected to the auxiliary circuit and a bridge moved by the contactor slide between a position for which it bears against the two terminals and connects them electrically to close the auxiliary circuit and a position for which it is remote from said terminals to open the auxiliary circuit.

Les contacteurs sont usuellement conçus avec un coulisseau muni de plusieurs plots, par exemple quatre ou six, dépassant de leur face avant, et des moyens permettant l'accrochage de blocs auxiliaires.The contactors are usually designed with a slide provided with several studs, for example four or six, protruding from their front face, and means allowing the attachment of auxiliary blocks.

Les blocs auxiliaires renfermant un seul contact sont de largeur telle qu'ils peuvent être montés les uns à côté des autres sur la face d'un contacteur de manière telle que chaque contact auxiliaire contenu dans un bloc auxiliaire soit commandé en déplacement par un plot du coulisseau du contacteur.The auxiliary blocks containing a single contact are of such width that they can be mounted next to each other on the face of a contactor so that each auxiliary contact contained in an auxiliary unit is controlled in movement by a stud of the contactor slide.

Le dispositif selon l'invention concerne la réalisation de blocs auxiliaires renfermant un contact auxiliaire étanche constitué par un interrupteur étanche, par exemple un micro rupteur. De tels appareils sont utilisés lorsque la fiabilité des interrupteurs classiques peut être compromise par l'environnement, en particulier lorsque ces interrupteurs sont destinés à être placés dans des circuits de contrôle ou de commande à bas niveaux, c'est-à-dire à courants faibles.The device according to the invention relates to the production of auxiliary blocks containing a sealed auxiliary contact constituted by a switch waterproof, for example a micro switch. Such devices are used when the reliability of conventional switches can be compromised by the environment, especially when these switches are intended for be placed in low-level control or command circuits, that is to say at low currents.

Un interrupteur étanche est de manière usuelle constitué d'un corps étanche portant d'une part des bornes électriques et d'autre part un levier de commande monté basculant de manière à pivoter entre une position de commande pour laquelle il est proche de la surface du corps étanche et une position de repos pour laquelle il est éloigné dudit corps étanche.A sealed switch usually consists of a body watertight carrying on the one hand electrical terminals and on the other hand a lever control unit tilting so as to pivot between a position for which it is close to the surface of the sealed body and a rest position for which it is distant from said sealed body.

Dans le dispositif décrit dans le FR 2 643 503, l'interrupteur étanche est commandé par un râteau coulissant le long du corps étanche et agissant, par le dessus, sur le levier de commande par l'intermédiaire d'un poussoir élastique destiné à absorber la différence de course entre le coulisseau du contacteur et le levier de l'interrupteur. Pour la mise en place du râteau de commande, il est nécessaire de disposer de place dans le bloc auxiliaire pour faire coulisser le râteau le long du corps étanche, c'est pourquoi le bloc auxiliaire décrit dans ce document a été conçu pour renfermer quatre contacts auxiliaires disposés dans des sections parallèles les unes aux autres, dont deux seulement desdits contacts auxiliaires sont étanches.In the device described in FR 2 643 503, the waterproof switch is controlled by a rake sliding along the waterproof and acting body, from above, on the control lever via a pusher elastic intended to absorb the difference in travel between the slide of the switch and switch lever. For placing the rake space, it is necessary to have space in the block auxiliary to slide the rake along the watertight body, it is why the auxiliary unit described in this document was designed to contain four auxiliary contacts arranged in sections parallel to each other, only two of which are said contacts auxiliaries are waterproof.

Ceci a pour conséquence qu'avec un contacteur ayant une largeur standard de 45 millimètres, par lequel il est possible de commander quatre contacts auxiliaires, on est limité à la mise en place de deux contacts étanches.This has the consequence that with a contactor having a width 45 mm standard, by which it is possible to order four auxiliary contacts, one is limited to the installation of two waterproof contacts.

La présente invention a alors pour but de proposer un montage permettant de proposer un bloc auxiliaire à contact étanche susceptible d'être monté en lieu et place d'un bloc auxiliaire de type connu pour être commandé par l'un des plots du coulisseau. The object of the present invention is therefore to propose an assembly making it possible to propose an auxiliary block with sealed contact capable of to be fitted in place of an auxiliary block of a type known to be controlled by one of the blocks on the slide.

A cet effet, l'objet de l'invention est un bloc auxiliaire à contact étanche du type comportant un boítier présentant des moyens d'encliquetage et une face ouverte et renfermant deux contacts fixes solidaires de deux bornes accessibles de l'extérieur dudit boítier et un interrupteur étanche constitué par un corps étanche portant deux bornes reliées respectivement à chacun des contacts fixes et un levier de commande, destiné à être monté sur un contacteur afin que l'état du contact soit modifié en fonction de l'état du coulisseau dudit contacteur, caractérisé en ce que ledit interrupteur étanche est disposé dans le boítier avec ledit levier de commande dirigé vers la face ouverte dudit boítier afin que l'état du contact soit modifié par un appui direct du coulisseau sur ledit levier de commande.To this end, the object of the invention is an auxiliary block with sealed contact of the type comprising a housing having latching means and an open face and containing two fixed contacts integral with two terminals accessible from outside said housing and a waterproof switch constituted by a waterproof body carrying two connected terminals respectively to each of the fixed contacts and a control lever, intended to be mounted on a contactor so that the state of the contact is modified according to the state of the slide of said contactor, characterized in that said waterproof switch is disposed in the housing with said control lever directed towards the open face of said housing so that the state of the contact is modified by direct pressing of the slide on said control lever.

Le bloc auxiliaire selon l'invention est encore remarquable en ce que :

  • l'interrupteur étanche est un interrupteur à fermeture lorsque le circuit auxiliaire est ouvert en position de travail du contacteur,
  • l'interrupteur étanche est un interrupteur à ouverture lorsque le circuit auxiliaire est fermé en position de travail du contacteur,
  • une butée est formée dans le boítier du bloc auxiliaire afin de limiter la course du levier de commande,
  • il renferme un seul interrupteur étanche et est monté au-dessus d'un plot du coulisseau,
  • il renferme plusieurs interrupteurs étanches et est monté au-dessus d'un nombre correspondant de plots du coulisseau.
The auxiliary unit according to the invention is also remarkable in that:
  • the sealed switch is a closing switch when the auxiliary circuit is open in the working position of the contactor,
  • the waterproof switch is an opening switch when the auxiliary circuit is closed in the working position of the contactor,
  • a stop is formed in the housing of the auxiliary unit in order to limit the travel of the control lever,
  • it contains a single waterproof switch and is mounted above a block of the slide,
  • it contains several sealed switches and is mounted above a corresponding number of slider studs.

L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif en référence aux figures 1 et 2 annexées représentant en vue de côté le bloc auxiliaire selon l'invention monté sur la face avant d'un contacteur, respectivement dans la position de repos et dans la position de travail du coulisseau du contacteur.The invention will be better understood thanks to the description which follows given by way of nonlimiting example with reference to FIGS. 1 and 2 attached representing in side view the auxiliary unit according to the invention mounted on the front face of a contactor, respectively in the position in the working position of the contactor slide.

Sur les dessins joints, les éléments qui sont connus et non directement liés à l'invention ont été représentés en pointillés afin de ne pas surcharger le dessin.In the accompanying drawings, the elements which are known and not directly related to the invention have been shown in dotted lines so as not to overload the drawing.

Dans l'exemple de réalisation représenté au dessin le bloc auxiliaire selon l'invention renferme un seul contact, et est positionné au dessus de l'un des plots du coulisseau du contacteur.In the embodiment shown in the drawing, the auxiliary block according to the invention contains a single contact, and is positioned above one of the contactor slide pads.

Le boítier 1 du bloc auxiliaire est monté sur la face avant du contacteur 2 et maintenu en place de manière connue en soi par des moyens d'encliquetage 10, 11. De manière également connue en soi, le boítier 1 du bloc auxiliaire est obtenu par moulage de matière plastique et est fermé par un couvercle non représenté au dessin, le boítier et le couvercle étant montés l'un sur l'autre suivant un plan parallèle au plan du dessin.The housing 1 of the auxiliary unit is mounted on the front face of the contactor 2 and held in place in a manner known per se by means latching 10, 11. In a manner also known per se, the housing 1 of the auxiliary block is obtained by plastic molding and is closed by a cover not shown in the drawing, the housing and the cover being mounted one on the other along a plane parallel to the plane drawing.

La face 12 du boítier du bloc auxiliaire 1 destinée à être en appui contre le contacteur est ouverte de manière à permettre au plot 3 du coulisseau du contacteur 2 de pénétrer à l'intérieur dudit bloc auxiliaire en vue de commander l'interrupteur 4.The face 12 of the housing of the auxiliary unit 1 intended to be pressed against the contactor is open so as to allow the pad 3 of the slide of contactor 2 to penetrate inside said auxiliary unit in order to operate switch 4.

Le bloc auxiliaire 1 renferme deux contacts fixes 6 solidaires de deux bornes 8 accessibles de l'extérieur du boítier 1 et permettant la fixation d'éléments électriques, cosses ou fils électriques par exemple, raccordés au circuit auxiliaire et insérés dans les ouvertures A du boítier 1.The auxiliary unit 1 contains two fixed contacts 6 integral with two terminals 8 accessible from outside the housing 1 and allowing attachment of electrical elements, for example terminals or wires, connected to the auxiliary circuit and inserted into the openings A of the housing 1.

L'interrupteur étanche 4 est constitué par un corps étanche portant deux bornes 7 reliées respectivement à chacun des contacts fixes 6 du bloc auxiliaire et un levier de commande 5 monté pivotant afin de commander l'interrupteur lorsqu'il est proche du corps étanche en appuyant sur un poussoir 15.The waterproof switch 4 is constituted by a waterproof body carrying two terminals 7 connected respectively to each of the fixed contacts 6 of the block auxiliary and a control lever 5 pivotally mounted in order to control the switch when it is close to the waterproof body by pressing a pusher 15.

Suivant l'invention, ledit interrupteur étanche est disposé dans le boítier constituant le bloc auxiliaire de manière telle que ledit levier de commande soit dirigé vers la face 12 ouverte du boítier 1 du bloc auxiliaire.According to the invention, said waterproof switch is disposed in the housing constituting the auxiliary unit in such a way that said lever control is directed towards the open face 12 of the housing 1 of the block auxiliary.

Cette disposition permet d'obtenir une commande très simple de l'interrupteur étanche 4 : en position de repos (figure 1), le plot 3 du coulisseau du contacteur vient en appui contre ledit levier de commande 5, et, en position de travail (figure 2), le plot 3 du contacteur libère ledit levier de commande 5.This arrangement makes it possible to obtain a very simple command of the waterproof switch 4: in the rest position (FIG. 1), the pad 3 of the contactor slide bears against said control lever 5, and, in the working position (FIG. 2), the pad 3 of the contactor releases said contact control lever 5.

L'interrupteur étanche est disposé dans le boítier 1 du bloc auxiliaire de telle sorte qu'en position de repos le plot 3 du contacteur 2 maintienne le levier de commande 5 dans sa position de commande dudit interrupteur étanche.The waterproof switch is arranged in the housing 1 of the auxiliary unit of so that in the rest position the pad 3 of the contactor 2 maintains the control lever 5 in its control position of said switch waterproof.

Lorsque le plot 3 du coulisseau libère le levier de commande 5, au moment de son passage en position de travail, ledit levier libère son action sur le poussoir 15 en basculant sous l'effet d'un moyen élastique interne de rappel en position de repos et provoque le changement d'état de l'interrupteur étanche 4, celui-ci passant en position de repos.When the block 3 of the slide releases the control lever 5, at when it passes into the working position, said lever releases its action on pusher 15 by tilting under the effect of elastic means internal return to rest position and causes the change of state of the waterproof switch 4, the latter passing into the rest position.

En conséquence, si le circuit auxiliaire doit être ouvert lorsque le contacteur est en position de travail, l'interrupteur étanche 4 doit être un interrupteur à fermeture, c'est-à-dire un contact ouvert en position de repos, lorsque le levier est écarté du boítier de l'interrupteur, et fermé en position de travail, lorsque le levier est amené contre le boítier de l'interrupteur. Consequently, if the auxiliary circuit is to be opened when the contactor is in working position, waterproof switch 4 must be a closing switch, i.e. an open contact in the rest, when the lever is removed from the switch housing, and closed in working position, when the lever is brought against the housing the switch.

Respectivement, on choisit un interrupteur à ouverture si le circuit auxiliaire doit être fermé lorsque le contacteur est en position de travail.Respectively, we choose an opening switch if the circuit must be closed when the contactor is in the working position.

De manière préférée, une butée 9 est formée dans le boítier 1 du bloc auxiliaire afin de limiter la course du levier de commande 5 et de le maintenir dans une position convenable pour que le plot 3 du contacteur 2 agisse sur lui dans de bonnes conditions lors de son retour vers sa position de repos, quelle que soit sa course. Le bloc auxiliaire selon l'invention peut ainsi être monté sur une gamme très étendue de contacteurs.Preferably, a stop 9 is formed in the housing 1 of the block auxiliary in order to limit the travel of the control lever 5 and maintain in a suitable position so that the contactor pad 3 2 acts on him in good conditions when he returns to his rest position, whatever its course. The auxiliary unit according to the invention can thus be mounted on a very wide range of contactors.

Le montage suivant l'invention ne nécessite pas d'organes intermédiaires pour transmettre le déplacement du plot 3 du coulisseau 2 au levier de commande 5 de l'interrupteur étanche. Ceci présente d'une part l'avantage de ne pas augmenter le prix de revient du bloc auxiliaire et de faire directement dépendre l'encombrement en épaisseur du bloc auxiliaire de l'épaisseur du boítier de l'interrupteur étanche. Cette disposition permet d'obtenir des blocs auxiliaires de faible encombrement, avantageusement d'encombrement identique à celui des blocs auxiliaires à contact non étanche afin de pouvoir être montés en lieu et place de ceux-ci lorsqu'il est nécessaire de mettre en oeuvre un interrupteur étanche sur un circuit auxiliaire sans avoir à modifier l'installation. Comme pour les blocs auxiliaires de type connu, on peut alors juxtaposer quatre blocs auxiliaires étanches renfermant un seul interrupteur étanche sur un contacteur de 45 millimètres, chacun étant monté au-dessus d'un plot du coulisseau ou intégrer les quatre interrupteurs étanches dans un seul boítier positionné au-dessus des quatre plots du coulisseau. The assembly according to the invention does not require intermediate members to transmit the displacement of the stud 3 of the slide 2 to the lever control 5 of the waterproof switch. This presents on the one hand the advantage of not increasing the cost price of the auxiliary unit and of directly make the bulk of the block thickness depend auxiliary thickness of the waterproof switch housing. This arrangement makes it possible to obtain auxiliary blocks of low dimensions, advantageously of identical dimensions to that of auxiliary blocks with leaktight contact in order to be able to be mounted in place and place of these when it is necessary to implement a waterproof switch on an auxiliary circuit without having to modify the installation. As for auxiliary blocks of known type, one can then juxtapose four watertight auxiliary blocks containing a single waterproof switch on a 45-millimeter contactor, each being mounted above a slide block or integrate the four waterproof switches in a single box positioned above the four blocks of the slide.

Plus généralement, il est possible de proposer un bloc auxiliaire selon l'invention renfermant plusieurs interrupteurs étanches et monté au-dessus d'un nombre correspondant de plots du coulisseau.More generally, it is possible to propose an auxiliary block according to the invention comprising several sealed switches and mounted above a corresponding number of blocks on the slide.
