Description

L'invention se rapporte à un petit contacteur équipé d'un sous-ensemble d'interrupteurs auxiliaires amovible dans lequel le contacteur présente deux rangées parallèles de bornes principales alignées, une semelle d'accrochage pour un support, une pièce mobile d'électro-aimant, et une surface de fixation apte à coopérer avec des moyens de fixation du boîtier de ce sous-ensemble, ce dernier comportant un tiroir coulissant sur lequel sont montés des ponts de contacts mobiles coopérant avec des contacts fixes reliés à des bornes auxiliaires et un moyen d'accouplement apte à coopérer avec la pièce mobile.The invention relates to a small contactor equipped with a removable auxiliary switch sub-assembly in which the contactor has two parallel rows of aligned main terminals, a hooking plate for a support, a movable piece of electro- magnet, and a fixing surface capable of cooperating with means for fixing the housing of this sub-assembly, the latter comprising a sliding drawer on which are mounted bridges of mobile contacts cooperating with fixed contacts connected to auxiliary terminals and a coupling means able to cooperate with the moving part.

De tels dispositifs sont actuellement présentés sous des formes diverses qui permettent leur association avec un contacteur, soit sur une face avant de celui-ci, soit sur une face latérale. Si un bloc d'interrupteurs auxiliaires est fixé sur la face avant d'un contacteur la dimension en profondeur correspondant à cet empilage se trouve augmentée, et il n'est alors pas possible d'utiliser cette association dans des coffrets, tels que ceux utilisés pour les équipements domestiques, dont les dimensions, une fois équipés, ne doivent pas dépasser une dimension normalisée.Such devices are currently presented in various forms which allow their association with a contactor, either on a front face thereof, or on a lateral face. If a block of auxiliary switches is fixed on the front face of a contactor the depth dimension corresponding to this stacking is increased, and it is then not possible to use this association in boxes, such as those used for domestic equipment, the dimensions of which, once fitted, must not exceed a standardized dimension.

Si un bloc d'interrupteurs auxiliaires est fixé sur une face latérale perpendiculaire aux rangées des bornes de raccordement il n'est plus possible de placer deux contacteurs côte à côte on respectant une implantation régulière car un infertile, correspondant à la largeur du bloc, va séparer deux contacteurs voisins.If an auxiliary switch block is fixed on a side face perpendicular to the rows of connection terminals, it is no longer possible to place two contactors side by side respecting a regular layout because an infertile, corresponding to the width of the block, will separate two neighboring contactors.

L'invention se propose par suite de fournir un dispositif d'interrupteurs auxiliaire qui soit susceptible de ne pas augmenter l'encombrement en largeur ou l'encombrement en profondeur d'un contacteur particulier auquel il est associé.The invention therefore proposes to provide an auxiliary switch device which is capable of not increasing the overall width or the overall depth of a particular contactor with which it is associated.

Il peut paraître simple de disposer un bloc d'interrupteurs auxiliaires sur une autre face que la face frontale ou une face latérale une telle mesure se heurte toutefois à un certain nombre de difficultés ou de préjugés. D'une part, lorsque le contacteun est de petites dimensions, le volume occupé par les bornes de raccordement ne peut descendre en dessous d'une certaine valeur qui est déterminée soit directement par le nombre de bornes et par les précautions d'isolement à respecter, soit encore par les valeurs minimales que doivent avoir les surfaces de raccordement pour pouvoir établir sans chauffer le passage d'intensités déterminées ; il en résulte que la surface libre de cette autre face est fortement limitée par la présence des bornes de raccordement. D'autre part lorsque les dimensions de la face libre du contacteur sont faibles il n'est pas commode de prévoir sur celle-ci des zones de fixation susceptibles d'accueillir un bloc d'interrupteurs auxiliaires. Enfin on ne rencontre pas souvent des appareils interrupteurs dans lesquels une rangée de bornes de raccordement concernant des interrupteurs auxiliaires se trouve placée derrière la rangée de bornes de raccordement des contacts principaux du contacteur, car la nappe de conducteurs aboutissant aux bornes des contacts principaux est souvent considérée comme un obstacle à la mise en place, au raccordement et à la fixation du bloc d'interrupteurs auxiliaires.It may seem simple to have a block of auxiliary switches on a face other than the front face or a side face such a measure however encounters a certain number of difficulties or prejudices. On the one hand, when the contact is of small dimensions, the volume occupied by the connection terminals cannot drop below a certain value which is determined either directly by the number of terminals and by the insulation precautions to be observed , or again by the minimum values that the connection surfaces must have in order to be able to establish without heating the passage of determined intensities; it follows that the free surface of this other face is greatly limited by the presence of the connection terminals. On the other hand when the dimensions of the free face of the contactor are small it is not convenient to provide thereon fixing zones capable of accommodating a block of auxiliary switches. Finally, switchgear is not often encountered in which a row of connection terminals relating to auxiliary switches is placed behind the row of connection terminals for the main contactors of the contactor, since the conductor strip leading to the terminals of the main contacts is often considered an obstacle to the installation, connection and fixing of the auxiliary switch block.

Selon l'invention le résultat visé est atteint grâce au fait que le boîtier du sous-ensemble est placé contre une face latérale du corps du contacteur qui est parallèle à une rangée de bornes principales et qui est placée entre la semelle de fixation et des cloisons isolantes séparant ces bornes principales, ce boîtier présentant d'une part, à une première extrémité, des premiers moyens d'accrochage pivotants coopérant avec des premiers moyens de maintien placés sur le corps du contacteur et entre les trous de fixation de la semelle, et d'autre part, à une seconde extrémité opposée à la première, des seconds moyens d'accrochage coopérant par déformation élastique avec des seconds moyens de maintien placés sur ledit corps dans le voisinage immédiat de la rangée de bornes.According to the invention the desired result is achieved thanks to the fact that the housing of the sub-assembly is placed against a face side of the body of the contactor which is parallel to a row of main terminals and which is placed between the fixing plate and insulating partitions separating these main terminals, this housing having on the one hand, at a first end, first means of pivoting hooking cooperating with first holding means placed on the body of the contactor and between the fixing holes of the sole, and on the other hand, at a second end opposite to the first, second hooking means cooperating by elastic deformation with second holding means placed on said body in the immediate vicinity of the row of terminals.

Un petit contacteur 1 auquel est destiné le dispositif de contact auxiliaire 2 de l'invention comprend un corps 3 ayant une face plane latérale 4 comprise entre une pluralité de cloisons parallèles d'isolement 5 servant à séparer des bornes de puissance 6 alignées en rangée 16 dans un plan Q le long d'un axe XX' parallèle à cette face et une semelle 8 servant à son accrochage sur un support 9. Compte tenu du sens de montage habituel des contacteurs, voir figure 1, cette face latérale 4 est une face supérieure. Cette face latérale présente une ouverture oblongue 10 derrière laquelle se déplace, parallèlement à elle, une pièce mobile de l'électro-aimant 11 du contacteur qui est par exemple pourvue d'un trou ou d'une encoche ou d'une rainure d'accouplement 12 voir figure 2. Le sous-ensemble d'interrupteurs auxiliaires 2 qui est mécaniquement associé au contacteur comprend, voir figures 1 et 3, un boîtier 13 de forme prismatique qui présente principalement une face plane d'association 14 venant s'appliquer contre la face latérale 4, une rangée 15 de bornes auxiliaires d'interrupteurs 18, un doigt d'accouplement 17 apte à coopérer avec l'encoche 12 et des moyens de centrage et de fixation qui seront décrits ci-dessous. La rangée de bornes auxiliaires 15 est placée parallèlement à la rangée 16 de bornes de puissance lorsque le boîtier fixé sur le corps 3 se trouve dans un autre plan P.A small contactor 1 for which the auxiliary contact device 2 of the invention is intended comprises a body 3 having a flat side face 4 comprised between a plurality of parallel isolation partitions 5 serving to separate power terminals 6 aligned in row 16 in a plane Q along an axis XX ′ parallel to this face and a sole 8 serving for its attachment to a support 9. Taking into account the usual mounting direction of the contactors, see FIG. 1, this lateral face 4 is a face superior. This side face has an oblong opening 10 behind which moves, parallel to it, a moving part of the electromagnet 11 of the contactor which is for example provided with a hole or a notch or a groove of coupling 12 see FIG. 2. The sub-assembly of auxiliary switches 2 which is mechanically associated with the contactor comprises, see FIGS. 1 and 3, a housing 13 of prismatic shape which mainly has a planar association face 14 which is applied against the side face 4, a row 15 of auxiliary switch terminals 18, a coupling finger 17 able to cooperate with the notch 12 and centering and fixing means which will be described below. The row of auxiliary terminals 15 is placed parallel to the row 16 of power terminals when the housing fixed to the body 3 is in another plane P.

Des moyens de centrage qui permettent de donner au boîtier une position bien précise par rapport au corps sont constitues par deux ailes parallèles saillantes 19, 20 du boîtier qui pénètrent dans deux rainures parallèles 21, 22 du corps 3, ces dernières étant disposées sur deux faces latérales opposées 23, 24 qui sont perpendiculaires à la face latérale supérieure 4 et aboutissent à celle-ci, voir figures 1 et 2.Centering means which make it possible to give the housing a very precise position relative to the body are constituted by two projecting parallel wings 19, 20 of the housing which penetrate into two parallel grooves 21, 22 of the body 3, the latter being arranged on two faces opposite lateral sides 23, 24 which are perpendicular to and end at the upper lateral face 4, see FIGS. 1 and 2.

Les moyens de fixation du boîtier sur le corps comprennent d'une part des ergots 25, 26 qui sont placés à une extrémité 27 du boîtier et qui s'engagent dans des encoches 28, 29 du corps 3 placées sur ou au voisinage de la semelle 8 et d'autre part, des crochets élastiques 30, 31 qui sont placés à une extrémité opposée 36 et qui coopèrent avec les rebords 32, 33 placés au voisinage des cloisons d'isolement 5 ; dans un mode de réalisation préféré les encoches 28, 29 sont placées au voisinage des trous de fixation 34, 35 de la semelle 8 et entre ceux-ci et les rebords 32, 33 sont placés sur deux cloisons externes opposées 5' respectivement 5", voir figures 2, 3 et 4.The means for fixing the housing to the body comprise on the one hand pins 25, 26 which are placed at one end 27 of the housing and which engage in notches 28, 29 of the body 3 placed on or in the vicinity of the sole 8 and on the other hand, elastic hooks 30, 31 which are placed at an opposite end 36 and which cooperate with the flanges 32, 33 placed in the vicinity of the isolation partitions 5; in a preferred embodiment, the notches 28, 29 are placed in the vicinity of the fixing holes 34, 35 of the sole 8 and between these and the flanges 32, 33 are placed on two opposite external partitions 5 'respectively 5 ", see figures 2, 3 and 4.

L'accrochage du boîtier sur le corps s'effectue, voir figures 2, 5a et 5b, en présentant d'abord l'extrémité 27 au voisinage de la semelle 8 pour établir une coopération pivotante entre les ergots 25, 26 et les encoches 28, 29 et en rabattant ensuite, dans le sens de la flèche G, l'extrémité opposée 36 qui pivote autour de l'axe ZZ' passant par les encoches vers les cloisons d'isolement 5 et jusqu'à son encliquetage élastique avec les cloisons 5' et 5".The housing is attached to the body, see FIGS. 2, 5a and 5b, by first presenting the end 27 in the vicinity of the sole 8 to establish pivoting cooperation between the pins 25, 26 and the notches 28 , 29 and then folding back, in the direction of the arrow G, the opposite end 36 which pivots around the axis ZZ 'passing through the notches towards the isolation partitions 5 and until it is snap-fitted with the partitions 5 'and 5 ".

Le boîtier 2 du sous-ensemble d'interrupteurs auxiliaires comprend un couvercle 59 et un demi-boîtier 62 qui présente une cloison sensiblement centrale 37 qui est parallèle à la face d'association 14 et qui divise le boîtier en un premier volume externe ouvert 47 recevant les bornes auxiliaires 18 et en un second volume interne fermé 38 dans lequel sont disposés : deux ponts de contact mobiles 39, 40 aptes à coopérer avec deux paires de contacts fixes 41 respective ment 42, un tiroir de commande 43 apte à déplacer les ponts de contact, des tessorts de pression de contact 44, 45 qui sont respectivement associés à chaque pont de contact, et un ressort de rappel 46 qui donne au tiroir 43 une position de repos, voir figures 6, 7 et 8. Les contacts fixes sont portés par des pièces conductrices parallèles et réversibles telles que 48 qui traversent la cloison centrale 37 de façon telle que les pastilles des contacts fixes (et donc ultérieurement les pastilles de contact des ponts de contact mobiles) se trouvant placées dans un même plan R parallèle à ladite cloison.The housing 2 of the sub-assembly of auxiliary switches comprises a cover 59 and a half-housing 62 which has a substantially central partition 37 which is parallel to the association face 14 and which divides the housing into a first open external volume 47 receiving the auxiliary terminals 18 and in a second closed internal volume 38 in which are arranged: two movable contact bridges 39, 40 able to cooperate with two pairs of fixed contacts 41 respective ment 42, a control slide 43 able to move the contact bridges, contact pressure tessorts 44, 45 which are respectively associated with each contact bridge, and a return spring 46 which gives the drawer 43 a rest position , see Figures 6, 7 and 8. The fixed contacts are carried by parallel and reversible conductive parts such as 48 which pass through the central partition 37 in such a way that the pads of the fixed contacts (and therefore subsequently the pads of the bridges of mobile contact) being placed in the same plane R parallel to said partition.

Le tiroir de commande 43 sert à actionner des interrupteurs auxiliaires à fermeture F ou des interrupteurs auxiliaires à ouverture O.The control slide 43 is used to actuate auxiliary switches with closing F or auxiliary switches with opening O.

Dans le premier cas des ponts de.contact tels que 40, ainsi que des ressorts de pression 45, sont logés respectivement dans chacun de deux cadres parallèles 49, 50 placés aux extrémités opposées 51, 52 du tiroir 43, de part et d'autre d'une cavité centrale 53 d'axe YY' ; ces ponts sont donc dans le plan SS' visible à la figure 7. Cette cavité 53 sert à recevoir une extrémité mobile d'un faible ressort de rappel 46 dont l'autre extrémité, fixe, s'appuiera sur une paroi 68 du demi-boîtier 62, voir figures 8 et 9 et sa surface extérieure 73 sera utilisée pour opérer le guidage du tiroir, comme précisé plus loin.In the first case, contact bridges such as 40, as well as pressure springs 45, are respectively housed in each of two parallel frames 49, 50 placed at opposite ends 51, 52 of the drawer 43, on either side. a central cavity 53 of axis YY '; these bridges are therefore in the plane SS 'visible in FIG. 7. This cavity 53 serves to receive a movable end of a weak return spring 46 whose other end, fixed, will rest on a wall 68 of the half housing 62, see Figures 8 and 9 and its outer surface 73 will be used to operate the guide of the drawer, as specified below.

De tels ponts de contact ayant la fonction F se déplacent, lorsque le tiroir est associé au demi-boîtier, dans une première région 54 placée entre les contacts fixes 42 et l'extrémité 36 du boîtier.Such contact bridges having the function F move, when the drawer is associated with the half-housing, in a first region 54 placed between the fixed contacts 42 and the end 36 of the housing.

Dans le second cas, des ponts de contact tels que 39 et des ressorts de pression 44 sont placés, après retournement, dans une seconde région 55 du volume 38 qui est située entre les contacts fixes 41 retournés et un fond 56 constituant l'extrémité 27.In the second case, contact bridges such as 39 and pressure springs 44 are placed, after reversal, in a second region 55 of the volume 38 which is located between the fixed contacts 41 turned over and a bottom 56 constituting the end 27 .

On peut équiper le sous-ensemble d'interrupteurs auxiliaires 2 soit de deux interrupteurs F ou 0, soit d'un F et d'un 0.The sub-assembly of auxiliary switches 2 can be fitted either with two switches F or 0, or with an F and a 0.

Le tiroir 43 présente une cloison 67 de forme générale plate ayant sur une face 69 un doigt d'actionnement 17 et sur l'autre face 70 opposée les deux cadres 49, 50, la cavité 53 et deux cloisons 66, 65 parallèles à l'axe YY' et situées de part et d'autre de la cavité, voir figures 8, 9 et 6. La surface extérieure 73 de la cavité est guidée entre deux nervures 63, 64 parallèles à YY' qui sont disposées sur la cloison 37. Ces cloisons 66, 65 et nervures 63, 64 créent des chicanes qui concourent à l'isolement des deux interrupteurs.The drawer 43 has a partition 67 of generally flat shape having on one face 69 an actuating finger 17 and on the other opposite face 70 the two frames 49, 50, the cavity 53 and two partitions 66, 65 parallel to the axis YY ′ and located on either side of the cavity, see FIGS. 8, 9 and 6. The outer surface 73 of the cavity is guided between two ribs 63, 64 parallel to YY ′ which are arranged on the partition 37. These partitions 66, 65 and ribs 63, 64 create baffles which contribute to the isolation of the two switches.

Les cadres 49, 50 sont compris chacun entre des traverses supérieures 49', respectivement 50' placées dans la région 71 du tiroir qui possède la cavité et des traverses inférieures 49", respectivement 50" qui sont prolongées respectivement par deux ailes 57-58, 57'-58'.The frames 49, 50 are each comprised between upper crosspieces 49 ', respectively 50' placed in the region 71 of the drawer which has the cavity and lower crosspieces 49 ", respectively 50" which are extended respectively by two wings 57-58, 57'-58 '.

Un contact mobile 40 d'interrupteur de type F est guidé dans un cadre 50, le ressort de pression s'appuyant alors sur une traverse supérieure 50' et le pont de contact 40 venant en appui sur une traverse inférieure 50", tandis qu'un contact mobile en pont 39 d'interrupteur de type 0 vient en appui sur un côté opposé de la traverse inférieure 49" sous l'effet d'un ressort de pression 44 placé entre ce pont de contact et le fond 56 ; des ailes telles que 57, 57' et 58, 58' servent à guider latéralement un tel pont de contact, voir figures 8 et 9.A movable contact 40 of type F switch is guided in a frame 50, the pressure spring then being supported on an upper cross member 50 'and the contact bridge 40 coming to bear on a lower cross member 50 ", while a movable bridge contact 39 of type 0 switch comes to bear on an opposite side of the lower cross member 49 "under the effect of a pressure spring 44 placed between this contact bridge and the bottom 56; wings such as 57, 57 'and 58, 58' serve to guide such a contact bridge laterally, see FIGS. 8 and 9.

Les ponts de contact et les contacts fixes seront de préférence identiques à ceux des contacts principaux. Un couvercle 59, visible aux figures 7 et 9, et portant tout ou partie de la face d'application 14, sert à compléter le guidage latéral du tiroir et ferme le volume 38 lorsqu'il est associé au demi-boîtier 62. Ce couvercle, qui présente une ouverture oblongue 60 pour livrer le passage au doigt d'actionnement 17, pourrait porter les crochets élastiques 30, 31 et les ailes de guidage 19, 20, en vue, d'une part, de ne présenter que de faibles dispersions de dimensions et, d'autre part, d'être réalisé en un matériau compatible avec les fonctions élastiques des crochets.The contact bridges and the fixed contacts will preferably be identical to those of the main contacts. A cover 59, visible in FIGS. 7 and 9, and carrying all or part of the application face 14, serves to complete the lateral guidance of the drawer and closes the volume 38 when it is associated with the half-housing 62. This cover , which has an oblong opening 60 to deliver passage to the actuating finger 17, could carry the elastic hooks 30, 31 and the guide wings 19, 20, in view, on the one hand, of having only small dimensional dispersions and, on the other hand, of being made of a material compatible with the elastic functions of the hooks .

Toutefois, compte tenu du fait que les contact fixes d'interrupteurs sont associés directement au demi-boîtier 62, on obtiendra une meilleure chaîne de tolérance en rendant les crochets élastiques 30, 31 et les ailes de guidage 19, 20 solidaires de ce demi-boîtier ; les ergots 25, 26 peuvent être indifféremment solidaires du demi-boîtier ou du couvercle.However, given the fact that the fixed switch contacts are directly associated with the half-housing 62, a better tolerance chain will be obtained by making the elastic hooks 30, 31 and the guide wings 19, 20 integral with this half housing; the pins 25, 26 can be indifferently secured to the half-housing or the cover.

Tous les éléments de ce sous-ensemble 2 seront avantageusement réalisés par moulage d'un matériau thermo-plastique, en faisant appel à ceux d'entre eux qui conviennent plus particulièrement à l'obtention d'un bon isolement électrique et respectivement à l'obtention d'une élasticité compatible avec la fonction des crochets.All the elements of this sub-assembly 2 will advantageously be made by molding a thermo-plastic material, using those of them which are more particularly suitable for obtaining good electrical insulation and respectively for obtaining an elasticity compatible with the function of the hooks.
