Description

L'invention concerne un dispositif de fixation d'accessoires, notamment de contacts auxiliaires, sur la face avant d'un contacteur monobloc.The invention relates to a device for attaching accessories, in particular auxiliary contacts, to the front face of a one-piece contactor.

Généralement, sur un contacteur monobloc de petit calibre (quatre contacts principaux intégrés) les accessoires sont montés par éléments de un à quatre modules (un élément de quatre modules correspondant à la totalité de la surface de fixation).Generally, on a small gauge monobloc contactor (four integrated main contacts) the accessories are mounted in elements of one to four modules (one element of four modules corresponding to the entire mounting surface).

Les fixations d'accessoires constituées par 1, 2 ou 4 modules s'effectuent de façon connue, soit directement par encliquetage frontal, soit par tenons et glissières avec glissement de l'élément parallèlement à la surface de fixation jusqu'à butée.Accessory attachments consisting of 1, 2 or 4 modules are carried out in a known manner, either directly by front snap-fastening, or by tenons and slides with sliding of the element parallel to the fixing surface until it stops.

Les fixations par encliquetage frontal sont particulièrement utilisées pour les éléments à un module et comportent deux crochets s'encliquetant dans la surface de fixation (brevet n° 1 498 480 déposé en FRANCE). Ce mode de fixation, cependant-, nécessite une opération supplémentaire pour accoupler les porte-contacts coulissants de l'accessoire et du contacteur.Front snap fasteners are particularly used for single-module elements and have two hooks that snap into the fastening surface (patent no. 1,498,480 filed in FRANCE). This method of attachment, however, requires an additional operation to couple the sliding contact carriers of the accessory and the contactor.

La fixation par tenon et glissière est particulièrement utilisée pour les accessoires à 2 ou 4 modules, mais devient très délicate pour la fixation d'un seul module. En effet, ce système comporte deux ensembles superposés à tenon et glissière.The fixing by tenon and slide is particularly used for the accessories with 2 or 4 modules, but becomes very delicate for fixing a single module. Indeed, this system comprises two superimposed sets with tenon and slide.

Un tel système à tenon et glissière Haut et tenon et glis- sière Bas nécessite en général, pour un montage facile et une bonne tenue mécanique, un dimensionnement des tenons et des glissières incompatibles avec la largeur d'un module, ou au moins, un pré-positionnement frontal de l'accessoire avant engagement des glissières. De ce fait, on n'utilise ce mode de fixation que pour des éléments de 2 ou 4 modules.Such a system and tenon and tenon and slide Top glis- s st Netherlands generally requires, for easy assembly and good mechanical strength, sizing pins and slides incompatible with the width of a module, or at least, front pre-positioning of the accessory before engaging the slides. Therefore, this method of attachment is only used for elements of 2 or 4 modules.

L'existence d'accessoires à au moins deux modules présente, comme par exemple dans le cas des contacts auxiliaires où un contact occupe un module, un inconvénient majeur pour l'uti- lisateur qui doit avoir un stock des modèles différents dont chacun présente une configuration particulière.The existence of at least two accessories in this module, such as in the case of auxiliary contacts where contact is housed in a module, a major drawback for UTI l i s creator who must have a stock of the different models of which each one has a particular configuration.

En effet, dans le cas de contacts auxiliaires, les éléments à deux modules doivent être de 4 types différents: un premier typé avec deux contacts de fermeture; un second avec un contact de fermeture puis un contact d'ouverture, dans l'ordre; un troisième avec un contact d'ouverture et un contact de fermeture dans l'ordre; et un quatrième avec deux contacts d'ouverture.Indeed, in the case of auxiliary contacts, the elements with two modules must be of 4 different types: a first typed with two closing contacts; a second with a closing contact then an opening contact, in order; a third with an opening contact and a closing contact in order; and a fourth with two opening contacts.

Dans le cas d'éléments à quatre modules, le nombre de types à fabriquer est de 16.In the case of elements with four modules, the number of types to be manufactured is 16.

Du fait que sur les contacteurs monoblocs à fixation par tenon et glissière pour quatre modules au maximum, le dispositif de fixation est central à cause de la largeur du système d'accrochage, on ne peut pas fixer l'élément à trois modules car la fixation serait alors décentrée par rapport à l'élément et celui-ci serait déséquilibré.Because the one-piece contactors with tenon and slide fastening for up to four modules, the fastening device is central because of the width of the hanging system, the element cannot be fixed to three modules because the fastening would then be off center with respect to the element and this one would be unbalanced.

est donc intéressant de pouvoir disposer d'éléments à un seul module pouvant se fixer sur le contacteur à l'un des quatre emplacements possibles tout en ayant une fixation sûre et une largeur telles que l'on puisse en fixer deux, trois ou quatre côte à côte sur le contacteur.it is therefore interesting to be able to have elements with a single module which can be fixed on the contactor to one of the four possible locations while having a secure fixing and a width such that one can fix two, three or four side by side on the contactor.

Les avantages d'un tel élément sont multiples. Entre autres, pour les contacts auxiliaires, il suffit de fabriquer un type d'élément à contact d'ouverture et un type d'élément à contact de fermeture que l'on pourra disposer selon les besoins sur le contacteur.The advantages of such an element are manifold. Among other things, for the auxiliary contacts, it suffices to manufacture a type of element with opening contact and a type of element with closing contact which can be placed as required on the contactor.

Pour l'utilisateur, il suffira pour passer de deux à trois modules par exemple, d'acheter un troisième module qui sera fixé à côté des précédents, alors que jusqu'ici avec les éléments. connus à 2 ou 4 modules, il fallait remplacer l'élément à deux modules par un élément à quatre modules (l'élément à deux modules n'étant plus utilisé et le quatrième module de l'élément à quatre modules étant inutile).For the user, it will be enough to go from two to three modules for example, to buy a third module which will be fixed next to the previous ones, while so far with the elements. known with 2 or 4 modules, it was necessary to replace the element with two modules by an element with four modules (the element with two modules being no longer used and the fourth module of the element with four modules being useless).

L'invention a donc pour but de procurer un élément à un seul module dont la fixation sur le contacteur soit sûre. Selon l'invention, cette fixation combine le système à crochet d'encliquetage qui permet d'avoir une faible largeur pour l'élément, et le système à tenon et glissière qui assure une fixation parfaite et permet en outre un guidage de l'élément lors de sa mise en place.The invention therefore aims to provide an element with a single module whose attachment to the switch is secure. According to the invention, this attachment combines the snap hook system which makes it possible to have a small width for the element, and the tenon and slide system which ensures perfect attachment and also allows the element to be guided. during its installation.

A cet effet, le dispositif comporte:

  • - un tenon en forme de T disposé sur la face du contacteur à l'emplacement de fixation de l'accessoire, coopérant avec une glissière située à la base de l'accessoire sur sa face dirigée vers le contacteur;
  • - un crochet disposé à la partie supérieure de l'accessoire sur sa face tournée vers le contacteur, coopérant avec un rebord d'un alvéole situé dans le contacteur; et
  • - un cliquet situé sur l'accessoire pouvant pénétrer dans un trou rectangulaire de la face du contacteur pour verrouiller l'accessoire en position accrochée en empêchant un déplacement vertical de l'accessoire par rapport au contacteur.
To this end, the device comprises:
  • - A T-shaped pin arranged on the face of the contactor at the location for fixing the accessory, cooperating with a slide located at the base of the accessory on its face directed towards the contactor;
  • - A hook disposed at the upper part of the accessory on its face facing the contactor, cooperating with a rim of a cell located in the contactor; and
  • - a ratchet located on the accessory that can penetrate into a rectangular hole in the face of the contactor for locking the accessory in the hooked position preventing vertical movement of the accessory relative to the contactor.

L'accessoire comporte un coulisseau porte-contacts également relié à un coulisseau du contacteur par un ensemble à tenon et glissière.The accessory comprises a contact carrier slide also connected to a contactor slide by a stud and slide assembly.

L'invention va à présent être décrite au moyen d'un exemple de réalisation représenté au dessin annexé dont :

  • La figure 1 est une vue de côté et en coupe partielle verticale du système de fixation d'un contact auxiliaire sur un contacteur monobloc, et
  • La figure 2 est une vue en coupe horizontale selon la ligne II-II de la figure 1 du système à tenon et glissière.
The invention will now be described by means of an embodiment shown in the accompanying drawing, in which:
  • FIG. 1 is a side view in partial vertical section of the system for fixing an auxiliary contact to a one-piece contactor, and
  • Figure 2 is a horizontal sectional view along line II-II of Figure 1 of the stud and slide system.

La face avant 1 du contacteur monobloc sur laquelle viennent se fixer les accessoires, comporte dans sa partie inférieure au moins quatre tenons 2 en forme de T. Sa partie supérieure est plane et comporte un trou rectangulaire 18 ainsi qu'un alvéole 13 au-dessus de chaque tenon 2.The front face 1 of the one-piece contactor on which the accessories are fixed, comprises in its lower part at least four tenons 2 in the shape of a T. Its upper part is flat and has a rectangular hole 18 as well as a cell 13 above of each post 2.

L'alvéole 13 comporte à sa partie supérieure une rampe de glissement oblique 14 et à sa partie inférieure un rebord d'accrochage 15. Le coulisseau 3 du contacteur comporte, à son extrémité externe au contacteur, des tenons 4 également en T situés au-dessus de chaque tenon 2 et en nombre égal.The cell 13 has at its upper part an oblique sliding ramp 14 and at its lower part a hooking flange 15. The slide 3 of the contactor comprises, at its end external to the contactor, pins 4 also in T located at- above each tenon 2 and in equal number.

Le contact auxiliaire 5 qui, dans l'exemple,est un contact de fermeture à un module, comporte sur la partie supérieure dela face 7 se fixant au contacteur un crochet 6 dirigé vers le bas pour l'accrochage sur le rebord 15 du contacteur et un chanfrein 11 au-dessus du crochet destiné à glisser contre la rampe 14. A la partie inférieure de la face 7 se trouve un évidement 8 dont une partie 8a permet le passage de la tête 9a du coulisseau porte-contacts 9 et une partie 8b, située au-dessous, est pourvue de deux épaississements latéraux 10 formant une glissière en T correspondant au tenon en T2 du contacteur. L'extrémité 9a du coulisseau 9 est également conformée en glissière correspondant au tenon en T4 du coulisseau 3 du contacteur.The auxiliary contact 5 which, in the example, is a closing contact to a module, comprises on the upper part of the face 7 which is fixed to the contactor a hook 6 directed downwards for hooking on the flange 15 of the contactor and a chamfer 11 above the hook intended to slide against the ramp 14. At the bottom of the face 7 is finds a recess 8 of which a part 8a allows the passage of the head 9a of the contact carrier slide 9 and a part 8b, located below, is provided with two lateral thickenings 10 forming a T-shaped slide corresponding to the pin in T2 of the contactor . The end 9a of the slide 9 is also shaped as a slide corresponding to the pin in T4 of the slide 3 of the contactor.

Dans un. évidement situé en arrière du crochet 6 se trouve un cliquet basculant 17 dont une saillie 16 dépasse du module sous le crochet 6 lorsque le cliquet est sollicité vers la droite (selon la figure 1) par sa partie élastique 19. Un bras 20 du cliquet 17 permet à celui-ci de buter contre la paroi de l'évidement et d'être maintenu dans la position où la saillie 16 dépasse sous le crochet 6.In one. recess located behind the hook 6 is a tilting pawl 17 whose projection 16 protrudes from the module under the hook 6 when the pawl is biased to the right (according to Figure 1) by its elastic part 19. An arm 20 of the pawl 17 allows the latter to abut against the wall of the recess and to be held in the position where the projection 16 projects under the hook 6.

La mise en place de l'accessoire 5 s'effectue comme suit:

  • L'opérateur place l'accessoire en face de la position choisie sur le contacteur où il doit être accroché, dans une position légèrement inclinée vers l'arrière de façon à ce que la glissière 8b, 10 s'engage légèrement sur le tenon 2 du contacteur, et la tête 9a du coulisseau 9, qui se pré- positionne naturellement, s'engage légèrement sur le tenon 4 du coulisseau 3 du contacteur.
The fitting of accessory 5 is carried out as follows:
  • The operator places the accessory opposite the chosen position on the contactor where it must be hung, in a position slightly inclined towards the rear so that the slide 8b, 10 engages slightly on the lug 2 of the contactor, and the head 9a of the slide 9, which is naturally pre-positioned, engages slightly on the lug 4 of the slide 3 of the contactor.

Le chanfrein 11 rencontre alors la rampe 14 et l'accessoire est basculé dans la position verticale, le mouvement vers le bas étant poursuivi, le crochet 6 pénètre dans l'alvéole 13 et la saillie 16 du cliquet 17 bute contre le rebord 15. Le cliquet est alors basculé vers l'arrière contre la partie élastique 19. La glissière 8b, 10 est alors enfilée sur le tenon 2, les épaississements 10 sont engagés dans les rainures 12 de celui-ci, et le crochet 6 est accroché au rebord 15 bloquant ainsi l'accessoire. La saillie 16 du cliquet 17 a pénétré dans le trou rectangulaire 18 et, sous la pression de la partie élastique 19, verrouille l'accessoire dans la position accrochée en empêchant tout déplacement vertical de celui-ci par rapport au contacteur.The chamfer 11 then meets the ramp 14 and the accessory is tilted in the vertical position, the downward movement being continued, the hook 6 enters the cell 13 and the projection 16 of the pawl 17 abuts against the rim 15. The ratchet is then tilted back against the elastic part 19. The slide 8b, 10 is then threaded on the pin 2, the thickenings 10 are engaged in the grooves 12 thereof, and the hook 6 is hooked to the flange 15 thus blocking the accessory. The projection 16 of the pawl 17 has entered the rectangular hole 18 and, under the pressure of the elastic part 19, locks the accessory in the hooked position preventing any vertical displacement of this in relation to the contactor.

Pour le décrochage, il suffit de ramener le bras 20 du cliquet vers l'arrière, selon la figure, et d'effectuer la série de mouvements précités dans l'ordre inverse, l'accessoire étant retiré après le basculement vers l'arrière qui dégage le crochet 6 de l'alvéole 13.For detachment, it suffices to bring the arm 20 of the pawl backwards, according to the figure, and to carry out the series of aforementioned movements in reverse order, the accessory being removed after the rearward tilting which releases the hook 6 from the socket 13.

Les avantages de l'invention sont multiples.The advantages of the invention are manifold.

Le crochet permet un accrochage sûr, tandis que la glissière inférieure peut garder des parois suffisamment épaisses pour être solides du fait qu'elle ne doit pas passer par une glissière ou un tenon supérieur jouant le même rôle.The hook allows a secure attachment, while the lower slide can keep walls thick enough to be solid because it does not have to pass through a slide or an upper tenon playing the same role.

Par son faible encombrement, ce système d'accrochage permet de réaliser des accessoires à un seul module, ce qui permet d'en disposer 1, 2, 3 et/ou 4 au choix sur le contacteur.Due to its small size, this attachment system makes it possible to produce accessories with a single module, which makes it possible to have 1, 2, 3 and / or 4 as desired on the contactor.

L'accrochage du coulisseau porte-contacts au coulisseau du contacteur est assuré dès la mise en place du contact auxiliaire sans manipulation ultérieure.The attachment of the contact carrier slide to the contactor slide is ensured as soon as the auxiliary contact is put in place without subsequent manipulation.

Il va de soi qu'un tel accessoire mono-module peut se monter, en nombre plus ou moins grand, sur des contacteurs de taille supérieure (c'est-à-dire à module propre plus large); il suffit pour cela de prévoir sur ces contacteurs les détails de fixation et les détails d'accouplement du coulisseau dans la largeur du module de l'accessoire.It goes without saying that such a single-module accessory can be mounted, in greater or lesser number, on contactors of larger size (that is to say with a larger clean module); it suffices for this to provide on these contactors the fixing details and the coupling details of the slide in the width of the accessory module.

Il est évident que l'invention ne se limite pas à l'accrochage de contacts auxiliaires mais peut également être utilisée pour l'accrochage d'autres éléments notamment des blocs à mémoire, des blocs de temporisation (à un, deux, trois ou quatre modules) etc., l'accrochage pouvant être effectué à partir du premier alvéole dans le cas d'un élément à moins de quatre modules.It is obvious that the invention is not limited to the attachment of auxiliary contacts but can also be used for the attachment of other elements in particular memory blocks, timing blocks (one, two, three or four modules) etc., the attachment can be carried out from the first cell in the case of an element with less than four modules.
