Description

La présente invention concerne un appareil électrique comportant un contacteur conformé de manière à pouvoir recevoir sur son embase un module de protection contre les surtensions et un module de protection.The present invention relates to an electrical device comprising a contactor shaped so as to be able to receive on its base a protection module against overvoltage and a protection module.

De manière connue en soi, un tel module de protection contre les surtensions est couplé à un contacteur soit pour protéger la bobine du contacteur contre des surtensions externes pouvant être générées entre ses bornes, soit pour protéger les dispositifs électroniques disposés à proximité du contacteur contre des parasites générés par les manoeuvres de l'électro-aimant.In a manner known per se, such a overvoltage protection module is coupled to a contactor either to protect the coil of the contactor against external overvoltages which can be generated between its terminals, or to protect the electronic devices placed near the contactor against parasites generated by the electromagnet operations.

Ces modules de protection sont usuellement montés sur les contacteurs après le câblage et la mise en service de ceux-ci, lorsque le besoin se fait sentir.These protection modules are usually mounted on the contactors after wiring and putting them into service, when the need arises.

Leur mise en place est alors souvent malaisée soit à cause du manque de place dans le montage électrique dont les accès sont rendus difficiles par la complexité du câblage électrique, soit du fait que les bornes de la bobine sont déjà occupées par deux câbles.Their installation is then often difficult either because of the lack of space in the electrical assembly whose access is made difficult by the complexity of the electrical wiring, or because the terminals of the coil are already occupied by two cables.

Il est parfois nécessaire de démonter des appareils électriques voisins du contacteur et de refaire le câblage du montage ce qui est très coûteux en temps de main d'oeuvre.It is sometimes necessary to dismantle electrical devices close to the contactor and to redo the assembly wiring, which is very costly in terms of labor time.

C'est pourquoi il a été proposé dans le brevet européen N° 0 198 099 de ménager dans l'une des faces latérales du contacteur un évidement dans lequel est totalement introduit le module de protection de sorte que sa face apparente soit dans le plan de la paroi transversale du contacteur. Cette disposition rend nécessaire l'utilisation d'un outil pour extraire le module de protection de son logement. Cette solution présente l'avantage d'inclure totalement le module dans le volume du contacteur défini vers le haut à partir des pieds de celui-ci mais le montage ou le démontage dudit module après l'installation du contacteur oblige à laisser un intervalle suffisant entre des contacteurs voisins d'un même montage.This is why it has been proposed in European Patent No. 0 198 099 to provide in one of the lateral faces of the contactor a recess in which the protection module is completely inserted so that its visible face is in the plane of the transverse wall of the contactor. This arrangement makes it necessary to use a tool to extract the protection module from its housing. This solution has the advantage of completely including the module in the volume of the contactor defined upwards from the feet of the latter, but the mounting or dismounting of said module after the installation of the contactor requires leaving a sufficient interval between neighboring contactors of the same assembly.

Cette solution présente également l'inconvénient d'occuper une partie importante de la place disponible au niveau des contacts.This solution also has the disadvantage of occupying a large part of the space available at the level of the contacts.

Par ailleurs, une telle solution n'est plus réalisable du fait que la géométrie des contacteurs a évolué et que les connexions électriques de la bobine sont maintenant usuellement placés tous les deux sur la face avant du contacteur.Furthermore, such a solution is no longer feasible because the geometry of the contactors has evolved and the electrical connections of the coil are now usually both placed on the front face of the contactor.

Le FR 2 631 738 propose un module constitué de deux portions parallélépipèdiques reliées par une portion plane de faible épaisseur. Les deux portions parallélépipèdiques sont destinées à être disposées dans des cavités formées à cet effet de part et d'autre de la face avant du contacteur au voisinage des bornes de celui-ci tandis que la portion plane est positionnée contre ladite face avant du contacteur. Le module de protection positionné sur le contacteur déborde alors de cette face avant du contacteur. Il peut avantageusement être mis en place ou retiré sans nécessiter le déplacement des contacteurs voisins. L'inconvénient principal que présente cette disposition est du au fait que lorsque le module est positionné sur le contacteur, ses deux portions parallélépipèdiques sont disposées dans les canaux permettant l'accès aux vis de fixation dudit contacteur ce qui oblige à démonter le module de protection lorsqu'il faut déplacer le contacteur.FR 2 631 738 proposes a module consisting of two parallelepipedic portions connected by a flat portion of small thickness. The two parallelepipedic portions are intended to be arranged in cavities formed for this purpose on either side of the front face of the contactor in the vicinity of the terminals thereof while the planar portion is positioned against said front face of the contactor. The protection module positioned on the contactor then extends beyond this front face of the contactor. It can advantageously be put in place or removed without requiring the displacement of neighboring contactors. The main disadvantage of this arrangement is that when the module is positioned on the contactor, its two parallelepipedic portions are arranged in the channels allowing access to the fixing screws of said contactor, which makes it necessary to dismantle the protection module. when the contactor has to be moved.

La présente invention tend alors à fournir un appareil comportant un contacteur et un module de protection conçus de manière telle qu'il soit toujours aisé de monter ou démonter le module de protection, la présence de ce module ne perturbant pas les interventions à pratiquer sur ce contacteur.The present invention therefore tends to provide an apparatus comprising a contactor and a protection module designed in such a way that it is always easy to mount or dismount the protection module, the presence of this module not disturbing the interventions to be carried out on this. contactor.

A cet effet, l'invention propose un appareil électrique du type comportant un contacteur présentant un logement pour la mise en place d'un module de protection et un module de protection, ledit contacteur comportant une embase sur laquelle sont montés les différents éléments électriques le composant et présentant des pieds situés aux quatre coins de sa face arrière pour la mise en place de vis de fixation, l'espace présent au-dessus desdits pieds étant laissé libre afin de permettre l'accès aux vis de fixation, ledit logement étant prévu sur l'une des parois dudit contacteur, et ledit module de protection étant conformé de sorte que l'ensemble formé par le contacteur et le module de protection qu'il porte ne dépasse pas du volume défini vers le haut à partir des pieds et laisse libre l'espace au-dessus desdits pieds nécessaire à l'accès aux vis de fixation, caractérisé en ce que ledit logement s'étend sur toute la largeur de la paroi de l'embase, le module de protection étant susceptible d'être mis en place, ou extrait, par saisie sur ses faces latérales.To this end, the invention provides an electrical device of the type comprising a contactor having a housing for the installation of a protection module and a protection module, said contactor comprising a base on which the various electrical elements are mounted. component and having feet located at the four corners of its rear face for the installation of fixing screws, the space present above said feet being left free to allow access to the fixing screws, said housing being provided on one of the walls of said contactor, and said protection module being shaped so that the assembly formed by the contactor and the protection module which it carries does not exceed the volume defined upwards from the feet and leaves free the space above said feet necessary for access to the fixing screws, characterized in that said housing extends over the entire width of the wall of the base, the module d e protection being capable of being put in place, or extracted, by gripping on its side faces.

L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue de 3/4 avant en perspective du contacteur suivant l'invention et du module de protection avant montage,
  • la figure 2 est une vue en perspective de l'embase du contacteur équipée du module de protection,
  • la figure 3 est une vue de côté en perspective du module de protection.
The invention will be better understood thanks to the description which follows given by way of nonlimiting example with reference to the appended drawings in which:
  • FIG. 1 is a front 3/4 view in perspective of the contactor according to the invention and of the protection module before mounting,
  • FIG. 2 is a perspective view of the base of the contactor fitted with the protection module,
  • Figure 3 is a side perspective view of the protection module.

De manière connue et comme représenté à la figure 1, le contacteur comporte une embase 10 dans laquelle sont montés les différents éléments électriques le composant, principalement une bobine et un électro-aimant et une partie haute 1 portant les contacts.In known manner and as shown in Figure 1, the contactor comprises a base 10 in which are mounted the various electrical elements composing it, mainly a coil and an electromagnet and an upper part 1 carrying the contacts.

Par cette embase, le contacteur peut être mis en place dans un montage électrique soit en étant positionné sur un rail par l'ouverture 11, soit en étant fixé par des vis traversant les trous 12 prévus dans les pieds 13 situés aux quatre coins de la face arrière de l'embase 10. A cet effet, l'espace présent au-dessus des pieds 13 est laissé libre afin de permettre à un outil l'accès auxdites vis de fixation.By this base, the contactor can be put in place in an electrical assembly either by being positioned on a rail by the opening 11, or by being fixed by screws passing through the holes 12 provided in the feet 13 located at the four corners of the rear face of the base 10. For this purpose, the space present above the feet 13 is left free in order to allow a tool access to said fixing screws.

Les plages 14 permettant la réalisation des connexions électriques sont disposées sur la face avant de deux bras latéraux 15 disposés de part et d'autre d'une protubérance 17 centrale de la face supérieure de l'embase 10.The pads 14 allowing the electrical connections to be made are arranged on the front face of two lateral arms 15 arranged on either side of a central protuberance 17 of the upper face of the base 10.

Les différentes notions concernant la position ou l'orientation des éléments contenues dans la présente description doivent être comprises par rapport au contacteur accroché en position de service sur un support vertical.The different notions concerning the position or the orientation of the elements contained in this description must be understood in relation to the contactor hung in the service position on a vertical support.

Deux fentes 16 séparent les bras 15 de la protubérance 17. La protubérance 17 s'étend vers l'avant par rapport à la paroi supérieure 18 de l'embase tout en restant dans le volume défini vers le haut à partir des pieds 13, en considérant ceux-ci comme les quatre coins d'une base d'appui.Two slots 16 separate the arms 15 from the protuberance 17. The protrusion 17 extends forward relative to the upper wall 18 of the base while remaining in the volume defined upwards from the feet 13, considering these as the four corners of a base support.

Une paroi 19 de faible épaisseur relie les pieds 13.A thin wall 19 connects the feet 13.

La face supérieure de la protubérance 17 et le bord libre de la paroi 19 sont dans un même plan horizontal au plus disposé le long de la base d'appui.The upper face of the protuberance 17 and the free edge of the wall 19 are in the same horizontal plane at most disposed along the support base.

Deux contacts électriques formés par des broches 20 reliées aux connexions électriques 14 de la bobine s'étendent dans les fentes 16. Ces broches sont visibles à la figure 1, dans laquelle l'on a pratiqué un arrachement partiel permettant de mieux voir la broche située à droite sur cette figure.Two electrical contacts formed by pins 20 connected to the electrical connections 14 of the coil extend into the slots 16. These pins are visible in FIG. 1, in which a partial cut-out has been made to better see the pin located right in this figure.

Ces broches sont disposées à distance des ouvertures des fentes 16 dirigées vers le haut et vers l'avant de manière à éviter tout risque de contact intempestif au cours d'interventions sur le montage électrique.These pins are arranged at a distance from the openings of the slots 16 directed upwards and forwards so as to avoid any risk of untimely contact during interventions on the electrical assembly.

La protubérance 17 présente une encoche 21 dirigée vers la paroi 19.The protuberance 17 has a notch 21 directed towards the wall 19.

La paroi 19 présente deux ouvertures 22 disposées près de la paroi avant 18. Pour des raisons de facilités de moulage, ces ouvertures 22 sont débouchantes dans l'exemple de réalisation représenté au dessin.The wall 19 has two openings 22 arranged near the front wall 18. For reasons of molding facilities, these openings 22 are open in the embodiment shown in the drawing.

La conformation du contacteur qui vient d'être décrite permet de réserver dans le volume du contacteur, un espace libre entre la protubérance 17 et la paroi 19. Cet espace libre constitue un logement pour la mise en place du module de protection 3, ledit logement s'étendant sur toute la largeur de la paroi de l'embase, ici la face supérieure.The conformation of the contactor which has just been described makes it possible to reserve in the volume of the contactor, a free space between the protuberance 17 and the wall 19. This free space constitutes a housing for the installation of the protection module 3, said housing extending over the entire width of the wall of the base, here the upper face.

Le module de protection 3 destiné à être monté sur le contacteur décrit ci-dessus présente un boîtier 30 de largeur égale à l'espace libre dans le sens transversal du contacteur entre les pieds 13, de hauteur un peu inférieure à l'espace séparant la protubérance 17 de la paroi 19 et d'épaisseur égale à la distance séparant la paroi avant 18 de l'embase de l'avant de la protubérance 17.The protection module 3 intended to be mounted on the contactor described above has a housing 30 of width equal to the free space in the transverse direction of the contactor between the feet 13, of height a little less than the space separating the protrusion 17 of the wall 19 and of thickness equal to the distance separating the front wall 18 from the base of the front of the protrusion 17.

Ce boîtier 30 est surmonté de deux bras 31 verticaux disposés au-dessus dudit boîtier et de part et d'autre de celui-ci.This housing 30 is surmounted by two vertical arms 31 disposed above said housing and on either side thereof.

Le boîtier 30 est ainsi destiné à être positionné entre la protubérance 17 et la paroi 19 sans dépasser du volume défini vers le haut par les pieds. Les faces latérales 37 du boîtier 30 sont disposées entre les pieds 13 du contacteur et remontent vers les bras verticaux 31 ce qui permet au boîtier de ne pas empiéter dans l'espace laissé libre au-dessus desdits pieds pour d'une part laisser l'accès aux vis de fixation, et d'autre part permettre de saisir le module de protection par ses faces latérales.The housing 30 is thus intended to be positioned between the protuberance 17 and the wall 19 without exceeding the volume defined upwards by the feet. The lateral faces 37 of the housing 30 are disposed between the feet 13 of the contactor and go up towards the vertical arms 31 which allows the housing not to encroach on the space left free above said feet to on the one hand leave the access to the fixing screws, and on the other hand allow the protection module to be grasped by its lateral faces.

Les bras 31 sont pour leur part destinés à être positionnés dans les fentes 16.The arms 31 are for their part intended to be positioned in the slots 16.

Chaque bras 31 porte une languette de contact 32 connectée aux éléments électriques disposés dans le boîtier 30 et destinée à se positionner contre une broche 20 pour établir la connexion électrique entre le module de protection 3 et la bobine du contacteur.Each arm 31 carries a contact tab 32 connected to the electrical elements arranged in the housing 30 and intended to be positioned against a pin 20 to establish the electrical connection between the protection module 3 and the coil of the contactor.

Des moyens d'accrochage du module de protection 3 au contacteur sont prévus entre les faces supérieure 35 et inférieure 36 du module et respectivement la protubérance 17 et la paroi 19.Means for attaching the protection module 3 to the contactor are provided between the upper 35 and lower 36 faces of the module and the protuberance 17 and the wall 19 respectively.

Une languette flexible 33 destinée à coopérer avec l'encoche 21 de la protubérance 17 est prévue sur la face supérieure 35 du boîtier 30 disposée entre les bras 31. Cette languette peut être effacée en appuyant dans le sens de la flèche A (figure 1).A flexible tongue 33 intended to cooperate with the notch 21 of the protuberance 17 is provided on the face upper 35 of the housing 30 disposed between the arms 31. This tongue can be removed by pressing in the direction of the arrow A (FIG. 1).

Deux ergots 34 destinés à coopérer avec les ouvertures 22 de la paroi 19 sont formés sur la face inférieure 36 du boîtier 30.Two pins 34 intended to cooperate with the openings 22 in the wall 19 are formed on the underside 36 of the housing 30.

Pour la mise en place du module de protection sur le contacteur, l'on insère les bras 31 dans les fentes 16 et la languette 33 dans l'encoche 21.To install the protection module on the contactor, the arms 31 are inserted into the slots 16 and the tongue 33 into the notch 21.

L'on tire le module vers le haut de manière à effacer la languette 33 tandis qu'on le fait basculer de manière à amener la face 36 du boîtier au-dessus de la paroi 19.The module is pulled upwards so as to erase the tab 33 while it is tilted so as to bring the face 36 of the housing above the wall 19.

On laisse alors redescendre le module jusqu'à ce qu'il soit en appui sur la paroi 19 tandis que les ergots 34 pénètrent dans les ouvertures 22.The module is then allowed to descend again until it is in abutment on the wall 19 while the lugs 34 penetrate into the openings 22.

Le module de protection est ainsi appliqué contre la paroi latérale 18 du contacteur tout en pouvant être saisi par ses faces latérales 37.The protection module is thus applied against the side wall 18 of the contactor while being able to be grasped by its side faces 37.

L'on comprend qu'un volume de faible dimension laissé le long de la face supérieure présentant le logement pour le module de protection est suffisant pour permettre la mise en place et le retrait dudit module.It is understood that a small volume left along the upper face having the housing for the protection module is sufficient to allow the establishment and removal of said module.

Des variantes de réalisation peuvent bien entendu être mises en oeuvre sans sortir du cadre de la présente invention.Alternative embodiments can of course be implemented without departing from the scope of the present invention.

Ces variantes pourront par exemple constituer en des modifications des dimensions du volume laissé libre pour la mise en place du module de protection en fonction des circuits électriques à utiliser.These variants could, for example, constitute modifications of the dimensions of the volume left free for the installation of the protection module according to the electrical circuits to be used.

A cet effet, la paroi 19 peut être située à un autre niveau que sur les dessins et la protubérance 17 peut être d'épaisseur plus ou moins importante.For this purpose, the wall 19 may be located at another level than in the drawings and the protuberance 17 may be of greater or lesser thickness.

Le module de protection peut être fabriqué de manière simple et économique en formant le boîtier 30 et les pattes 31 en une pièce de matière plastique creuse obtenue par moulage. Dans cette pièce creuse, l'on dispose le circuit électrique qui doit le composer muni des languettes de contact 32, puis on noie ce circuit dans une résine durcissante qui assure le maintien des composants et leur résistance aux chocs et aux vibrations.The protection module can be manufactured in a simple and economical manner by forming the housing 30 and the tabs 31 in a piece of hollow plastic material obtained by molding. In this hollow part, there is the electrical circuit which must compose it provided with the contact tabs 32, then this circuit is drowned in a hardening resin which ensures the maintenance of the components and their resistance to shocks and vibrations.

La face avant de la pièce creuse est ainsi fermée par la résine.The front face of the hollow part is thus closed by the resin.

Cette face avant est disposée contre le contacteur et non visible de l'extérieur ce qui dispense d'une finition particulière.This front face is arranged against the contactor and not visible from the outside, which dispenses with a particular finish.
