Description

L'invention est relative à un dispositif formant socle d'enfichage de relais électrique. Un tel dispositif est décrit par exemple dans US-A-3 244 941.The invention relates to a device forming a base of electrical relay. Such a device is described for example in US-A-3,244,941.

On utilise habituellement dans le domaine aéronautique des panneaux de commande électrique comportant une pluralité de relais électriques situés sur un côté du panneau et enfichés chacun dans un socle correspondant par liaison mécanique démontable. Plus précisément; pour réaliser ce montage de relais électriques, on effectue tout d'abord des perçages et une découpe de contours normalisés dans un panneau d'épaisseur prédéterminée ; on introduit un socle d'enfichage pourvu de colonnettes de fixation par l'arrière ou l'avant du panneau à travers lesdits perçages et ladite découpe de manière que lesdites colonnettes dépassent des perçages ; en maintenant le socle en place, on introduit des rondelles sur les colonnettes, avant de solidariser celles-ci au panneau par vissage d'écrous à un couple prédéterminé ; on enfiche ensuite le relais électrique sur le socle de manière que les pattes percées de fixation du relais soient positionnées sur lesdites colonnettes ; enfin, on introduit d'autres rondelles sur les colonnettes et on réalise la solidarisation du relais au socle et au panneau par vissage d'autres écrous à un couple prédéterminé.Usually used in the aeronautical field electrical control panels having a plurality of electrical relays located on one side of the panel and each plugged into a corresponding base by connection removable mechanical. More precisely; to achieve this mounting of electrical relays, first of all holes and cutting of standardized contours in a panel of predetermined thickness; we introduce a base plug fitted with rear fixing columns or the front of the panel through said holes and said cut so that said columns protrude from drilling; keeping the base in place, we introduce washers on the balusters, before joining these to the panel by screwing nuts to a torque predetermined; then plug the electrical relay into the base so that the pierced fixing tabs of the relays are positioned on said columns; finally, we introduce other washers on the balusters and we carry out the connection of the relay to the base and panel by screwing other nuts to a torque predetermined.

Ce procédé de fixation est efficace, mais il conduit à une mise en oeuvre relativement longue résultant des positionnements successifs des rondelles et des vissages successifs des écrous, et il présente un risque important pour la fiabilité de fonctionnement en cas de perte de ces rondelles ou écrous susceptibles de provoquer des court-circuits ou des mises à la masse indésirables.

L'invention a pour but de perfectionner la technologie d'implantation des panneaux de commande électrique, en simplifiant la mise en oeuvre de la fixation des socles sur les panneaux électriques et en supprimant les risques de pertes de pièces détachées ou de petits objets métalliques, grâce à l'utilisation d'un nouveau dispositif formant socle d'enfichage.The invention aims to perfect the technology installation of electrical control panels, simplifying the implementation of the fixing of the bases on electrical panels and removing the risk of loss of spare parts or small metal objects, through the use of a new base device plug-in.

    • En référence à la figure 1, un dispositif selon l'invention comporte un corps 1 muni de logements 2 formant connecteurs électriques femelles aptes à coopérer avec les connecteurs mâles ou fiches d'un relais électrique non représenté, de manière à réaliser l'enfichage électrique du relais électrique et la solidarisation mécanique audit corps et à un panneau de montage non représenté.Referring to Figure 1, a device according to the invention comprises a body 1 provided with housings 2 forming connectors electric female able to cooperate with connectors pins or plugs of an electrical relay not shown, of so as to carry out the electrical connection of the relay electrical and mechanical connection to said body and to a mounting panel not shown.

    Aux extrémités du corps 1, deux embouts 3 et 4 comportent des taraudages 5 et 6 ou des inserts rapportés formant taraudage, ou un système à baïonnette, ou un système de blocage à quart de tour, ou un système push-pull. De part et d'autre de chaque embout 3 ou 4 en se rejoignant au-dessus de celui-ci, une paire de pattes d'encliquetage 7a, 7b ou 8a, 8b flexibles est disposée de manière à former une rainure d'encliquetage 9 ou 10 dont la hauteur est supérieure à l'épaisseur du panneau de réception.At the ends of the body 1, two end pieces 3 and 4 have threads 5 and 6 or inserted inserts forming tapping, or a bayonet system, or a quarter-turn locking, or a push-pull system. Departure and other of each tip 3 or 4 by joining above from it, a pair of latching tabs 7a, 7b or 8a, 8b flexible is arranged so as to form a snap groove 9 or 10 whose height is greater than the thickness of the receiving panel.

    Les pattes flexibles 7a, 7b, 8a, 8b sont délimitées par des rainures verticales 11 non débouchantes orientées longitudinalement et transversalement par rapport au corps 1, et présentent des ergots 12 surplombant les rainures 9 et 10.The flexible tabs 7a, 7b, 8a, 8b are delimited by oriented vertical grooves 11 not emerging longitudinally and transversely to the body 1, and have lugs 12 overhanging the grooves 9 and 10.

    Le débattement fonctionnel des pattes élastiques est limité par deux plans de guidage solidaires du socle, de manière que lesdites pattes travaillent, toujours dans des limites fonctionnelles optimales.The functional travel of the elastic legs is limited by two guide planes integral with the base, so that said legs work, always within limits optimal functional.

    Chaque ergot 12 comporte un plan incliné 13 d'engagement, une surface plane 14 et un rebord 15 formant bec d'encliquetage. Les plans inclinés se rejoignent au-dessus de chaque embout 3 ou 4 et sont interrompus au voisinage de l'axe longitudinal médian par un évidement cylindrique 16 sensiblement coaxial à l'alésage 5 ou 6. L'évidement 16 est prévu pour le passage d'un manchon 36 qui sera décrit ci-après.Each lug 12 has an inclined plane 13 of engagement, a flat surface 14 and a flange 15 forming a beak latching. The inclined planes meet above of each nozzle 3 or 4 and are interrupted in the vicinity of the median longitudinal axis through a cylindrical recess 16 substantially coaxial with bore 5 or 6. The recess 16 is provided for the passage of a sleeve 36 which will be described below.

    De manière analogue, les plans 14 sont interrompus au voisinage de l'axe longitudinal médian par ledit évidement cylindrique 16 selon une intersection comportant deux segments de génératrices verticales.Similarly, the plans 14 are interrupted at vicinity of the median longitudinal axis by said recess cylindrical 16 at an intersection with two vertical generator segments.

    En référence aux figures 2 à 4, le dispositif selon l'invention est inséré à travers une découpe normalisée d'un panneau 20, de manière que les taraudages ou inserts 5 et 6 soient sensiblement coaxiaux aux perçages 21 et 22 du panneau 20.Referring to Figures 2 to 4, the device according to the invention is inserted through a standardized cutout a panel 20, so that the threads or inserts 5 and 6 are substantially coaxial with the holes 21 and 22 of the panel 20.

    Avantageusement, les inserts 5, 6 font saillie au dessus de la face supérieure des embouts 3, 4, en présentant éventuellement un rétrécissement dans le plan de cette face supérieure pour assurer in indexage en pénétrant dans les perçages 21, 22 du panneau 20.Advantageously, the inserts 5, 6 protrude above the upper face of the end pieces 3, 4, having possibly a narrowing in the plane of this face upper to ensure indexing when entering the holes 21, 22 of the panel 20.

    Cette insertion s'obtient par simple poussée dans le sens de la flèche 19 : ce mouvement de poussée provoque le retrait élastique des pattes élastiques 7a, 7b, 8a, 8b vers le centre du corps 1 en raison de l'action de l'ouverture du panneau 20 sur les plans inclinés 13 des pattes élastiques 7a, 7b, 8a, 8b, puis le glissement des plans verticaux 14 sur les bords de ladite ouverture du panneau 20, et enfin le verrouillage par retour élastique des pattes 7a, 7b, 8a, 8b et des rebords 15 formant bec d'encliquetage au-dessus des bords correspondants de l'ouverture.This insertion is obtained by simple push in the direction arrow 19: this pushing movement causes the elastic withdrawal of the elastic tabs 7a, 7b, 8a, 8b towards the center of the body 1 due to the action of the opening of panel 20 on inclined planes 13 of legs elastic 7a, 7b, 8a, 8b, then the sliding of the planes vertical 14 on the edges of said opening of the panel 20, and finally the locking by elastic return of the tabs 7a, 7b, 8a, 8b and flanges 15 forming a beak snap over the corresponding edges of the opening.

    Dans la position d'insertion maximale de la figure 2, un jeu j est prévu entre le rebord 15 d'encliquetage et la surface supérieure en regard du panneau 20 ; le jeu j permet le montage sur des panneaux d'épaisseur variable dans une faible plage de variation, et garantit effectivement le bon encliquetage et le bon verrouillage des pattes élastiques 7a, 7b, 8a, 8b dans l'ouverture découpée dans le panneau 20, même en présence d'impuretés ou de poussières.In the maximum insertion position of Figure 2, a clearance j is provided between the ratchet flange 15 and the upper surface facing the panel 20; the game j allows mounting on panels of variable thickness within a small variation range, and guarantees actually the right snap and the right lock elastic tabs 7a, 7b, 8a, 8b in the opening cut in the panel 20, even in the presence of impurities or dust.

    Après avoir encliqueté le dispositif selon l'invention dans l'ouverture du panneau 20, on présente le relais 30 muni de pattes de fixation 31 en position d'accostage sur la figure 3.After having snapped the device according to the invention into the opening of the panel 20, there is the relay 30 provided with fixing lugs 31 in docking position in the figure 3.

    Dans cette position, au début de la pénétration des fiches mâles 32 dans les connecteurs électriques femelles 2 du corps 1, le relais maintient par ses faces latérales 30a et 30b les pattes élastiques 7a, 7b, 8a, 8b en position de verrouillage.In this position, at the beginning of the penetration of the cards 32 in the female electrical connectors 2 of the body 1, the relay maintains by its lateral faces 30a and 30b the elastic tabs 7a, 7b, 8a, 8b in the position of locking.

    On prévoit à cet effet que l'écartement entre les pattes 7a, 7b d'une part et les pattes 8a, 8b d'autre part corresponde sensiblement à la largeur du relais 30. Cette disposition empêche la libération du dispositif selon l'invention hors de l'ouverture du panneau 20 : en effet, l'enfichage complet des connecteurs électriques nécessite une poussée importante dans le sens opposé à la flèche 19 de la figure 2 et cette poussée pourrait provoquer le déverrouillage du dispositif par retrait élastique des pattes 7a, 7b, 8a, 8b vers le centre du corps 1, si ces pattes n'étaient pas maintenues écartées en position de verrouillage par les faces latérales 30a, 30b du relais électrique 30.It is provided for this purpose that the spacing between the legs 7a, 7b on the one hand and the legs 8a, 8b on the other hand corresponds approximately to the width of the relay 30. This provision prevents device release according to the invention outside the opening of the panel 20: in fact, complete insertion of the electrical connectors requires a significant thrust in the opposite direction to the arrow 19 in Figure 2 and this push could cause unlocking of the device by elastic withdrawal of the legs 7a, 7b, 8a, 8b towards the center of the body 1, if these legs were not kept apart in position locking by the lateral faces 30a, 30b of the relay electric 30.

    La poussée d'enfichage repousse le corps 1 vers le bas, de sorte que le jeu j précité qui apparaissait au-dessus du panneau 20 sur la figure 2 se retrouve au-dessous du panneau 20 sur la figure 3. The push-in push pushes the body 1 down, so that the aforementioned game j which appeared above the panel 20 in Figure 2 is found below the panel 20 in Figure 3.

    Ainsi, les pattes élastiques en position d'écartement sont en appui sur la face du panneau par leurs rebords 15 formant bec de verrouillage, et sont auto-verrouillées dans cette position par le relais électrique lors de sa présentation en position d'accostage.Thus, the elastic tabs in the spacing position are resting on the face of the panel by their edges 15 forming a locking spout, and are self-locking in this position by the electrical relay during its presentation in docking position.

    Après avoir été placé dans la position d'accostage de la figure 3, le relais électrique 30 est fixé au dispositif selon l'invention au travers du panneau 20.After being placed in the docking position of the Figure 3, the electrical relay 30 is fixed to the device according to the invention through the panel 20.

    A cet effet, sur les pattes de fixation 31 percées de trous 33 et 34, ont montées des vis 35 munies de rondelles d'appui et rendues imperdables par vissage dans des manchons 36 formant entretoise et taraudés à leurs extrémités supérieures. Ces manchons 36 sont rapportés, ou solidaires des pattes de fixation 31, et ils permettent l'adaptation d'un relais standard sur le socle objet de l'invention.For this purpose, on the fixing lugs 31 pierced with holes 33 and 34, mounted screws 35 fitted with washers support and made captive by screwing in sleeves 36 forming a spacer and tapped at their upper extremities. These sleeves 36 are attached, or integral with the fixing lugs 31, and they allow the adaptation of a standard relay on the base object of the invention.

    Les vis 35 sont ensuite vissées dans les taraudages ou inserts taraudés 5 ou 6 et serrées à un couple prédéterminé, de manière à maintenir fermement le panneau 20 entre le relais 30 et le dispositif selon l'invention, plus précisément entre une extrémité 3 ou 4 et un manchon formant entretoise 36.The screws 35 are then screwed into the threads or threaded inserts 5 or 6 and tightened to a torque predetermined, so as to hold the panel firmly 20 between the relay 30 and the device according to the invention, more precisely between an end 3 or 4 and a sleeve forming spacer 36.

    Dans la position de fixation du relais de la figure 4, le jeu j précité se retrouve au-dessus du panneau 20 et les pattes élastiques 7a, 7b, 8a, 8b restent maintenues écartées par les faces latérales 30a, 30b du relais électrique 30.In the fixing position of the relay in Figure 4, the game j above is found above the panel 20 and the elastic tabs 7a, 7b, 8a, 8b remain maintained separated by the side faces 30a, 30b of the relay electric 30.

    Un joint souple d'étanchéité 37 entre la face supérieure du panneau 20 et la face inférieure du relais 30 portant les fiches 32 est avantageusement prévu pour garantir l'étanchéité de cette interface, quelles que soient les variations d'épaisseur du panneau 20 à l'intérieur d'une plage admissible de variation. A flexible seal 37 between the upper face of the panel 20 and the underside of relay 30 carrying the sheets 32 is advantageously provided to guarantee the tightness of this interface, whatever the variations in thickness of the panel 20 inside a permissible range of variation.

    Ce joint souple 37 procure en outre une réaction élastique empêchant la propagation de vibrations susceptibles de desserrer les vis 35 ou d'introduire un jeu indésirable dans les connexions électriques et mécaniques du relais 30 et du dispositif selon l'invention.This flexible seal 37 also provides an elastic reaction preventing the propagation of vibrations liable to loosen screws 35 or introduce unwanted play in the electrical and mechanical connections of relay 30 and of the device according to the invention.

    Dans le deuxième mode de réalisation de la figure 5, le dispositif formant socle d'enfichage est constitué en deux parties assemblées par collage ou soudage par exemple. La première partie comprend un bloc central 39 et des pattes élastiques d'encliquetage 7 et 8. Le bloc central 39 présente des logements 2 formant connecteurs électriques, comme le corps 1 des figures 1 à 4, mais que ne sont pas représentés pour simplifier le dessin. Les pattes élastiques sont constituées d'une seule pièce mais présentent un évidement dans leur zone centrale.In the second embodiment of FIG. 5, the plug-in base device consists of two parts assembled by gluing or welding for example. The first part includes a central block 39 and legs snap elastic 7 and 8. The central block 39 has housings 2 forming electrical connectors, like the body 1 of figures 1 to 4, but which are not shown to simplify the drawing. The paws elastics are made in one piece but have a recess in their central area.

    La deuxième partie constitue un berceau 40 s'étendant entre les deux embouts 3 et 4, dont les taraudages 5 et 6 n'ont pas été représentés par simplification. Le berceau 40 est conformé pour recevoir la première partie du dispositif sur une surface de fond 43 et entre deux surfaces latérales 41 et 42. La surface de fond 43 est destinée à recevoir la première partie du dispositif de façon à réaliser un assemblage par soudage ou collage.The second part constitutes a cradle 40 extending between the two nozzles 3 and 4, whose threads 5 and 6 have not been represented for simplification. The cradle 40 is shaped to receive the first part of the device on a bottom surface 43 and between two lateral surfaces 41 and 42. The bottom surface 43 is intended to receive the first part of the device in order to achieve a assembly by welding or gluing.

    Les deux surfaces latérales 41 et 42 sont destinées à constituer des surfaces d'appui ou de butée pour les pattes 7 et 8, respectivement.The two lateral surfaces 41 and 42 are intended for constitute support or abutment surfaces for the legs 7 and 8, respectively.

    Les embouts 3 et 4 pénètrent dans les évidements de la zone centrale des pattes 7 et 8, et ils y portent une butée 38, visible également sur les figures 1A et 1B. Cette butée 38 est destinée à s'appliquer sur un bord de l'ouverture du panneau 20, de façon à éviter les translations du socle dans le plan du panneau sous l'action des efforts dus aux câbles de connexion électrique avant la mise en place du relais 30. En effet, en cas de translation du socle, l'une des pattes pourrait s'infléchir vers le centre du socle et l'autre patte pourrait alors échapper au panneau. Le socle ne serait alors plus encliqueté dans le panneau. Les butées 38 permettent d'éviter cet inconvénient.End caps 3 and 4 enter the recesses in the area central of the legs 7 and 8, and they carry a stop there 38, also visible in Figures 1A and 1B. This stop 38 is intended to be applied on an edge of the opening of the panel 20, so as to avoid translations of the base in the plane of the panel under the action of the forces due to electrical connection cables before installing the relay 30. Indeed, in case of translation of the base, one legs could bend towards the center of the base and the other leg could then escape the panel. Pedestal would no longer be snapped into the panel. The stops 38 allow this drawback to be avoided.

    La figure 6 correspond au cas d'une ouverture du panneau 20 susceptible de recevoir une série de dispositifs formant socles d'enfichage de relais, dont un seul est représenté. Pour simplifier les opérations de mise en place des relais dans les socles correspondants, les relais ne sont pas vissés individuellement sur les socles, mais ont enfichés et maintenus en position enfichée au moyen d'un cadre appliqué sur l'ensemble des relais et fixé par deux vis en 48 et 49 par exemple. Ce cadre s'étend sensiblement sur le tour de l'ouverture 50 du panneau 20.Figure 6 corresponds to the case of an opening of the panel 20 capable of receiving a series of devices forming relay socket-outlets, only one of which is shown. To simplify the operations of setting up relays in the corresponding sockets, the relays are not individually screwed on the bases, but plugged in and kept in the plugged-in position by means of a frame applied to all relays and fixed by two screws in 48 and 49 for example. This framework extends substantially over the around the opening 50 of the panel 20.

    Pour mettre en position correcte les socles 1 dans l'ouverture 50 du panneau 20, des orifices 44 sont prévus, régulièrement espacés dans le panneau 20, de part et d'autre de l'ouverture 50. Les socles 1, dans le troisième mode de réalisation des figures 6 et 7 présentent sur leurs embouts 3 et 4 des pions d'indexage 45 destinés à être insérés dans les orifices 44 au moment de la mise en place des socles dans l'ouverture 50 du panneau 20.To correctly position the bases 1 in the opening 50 of the panel 20, orifices 44 are provided, regularly spaced in panel 20, on both sides other of the opening 50. The bases 1, in the third embodiment of Figures 6 and 7 show on their end pieces 3 and 4 of the indexing pins 45 intended to be inserted in the holes 44 at the time of installation bases in the opening 50 of the panel 20.

    Dans le quatrième mode de réalisation des figures 8 et 9, les dispositifs 1 formant socles selon l'invention présentent des embouts 3, 4 munis de taraudages 5, 6 comme sur les figures 1 à 4.In the fourth embodiment of FIGS. 8 and 9, the devices 1 forming bases according to the invention have end pieces 3, 4 provided with threads 5, 6 as in Figures 1 to 4.

    Le panneau 20 comporte une ouverture 50 munie latéralement de trous oblongs 51, 52 destinés à remplacer les perçages 21, 22, respectivement, de la figure 2. Pour permettre de placer correctement les socles par rapport aux trous oblongs 51, 52, les socles sont munis de pions d'indexage 46 disposés latéralement, dans la rainure d'encliquetage (9, 10 de la figure 1A) c'est-à-dire dans une zone correspondant à l'épaisseur du panneau 20. Les socles étant ainsi mis en place, les relais peuvent y être fixés par vissage à travers les trous oblongs 51, 52.The panel 20 has an opening 50 provided laterally oblong holes 51, 52 intended to replace the holes 21, 22, respectively, of Figure 2. To allow correctly place the bases in relation to the holes oblong 51, 52, the bases are provided with indexing pins 46 arranged laterally in the snap groove (9, 10 in FIG. 1A), that is to say in an area corresponding to the thickness of the panel 20. The bases being thus installed, the relays can be attached to it by screwing through the oblong holes 51, 52.

    L'invention supprime les risques de perte de pièces métalliques en prévoyant uniquement l'utilisation de deux pièces importantes : le dispositif précité et un relais 30 équipé de vis imperdables. En outre, la mise en place d'un socle selon l'invention peut être effectuée manuellement, sans utiliser aucun outil, à l'aide d'une poussée dans le sens de la flèche 19 correspondant à une faible force d'insertion.The invention eliminates the risk of losing parts metallic, providing only for the use of two important parts: the aforementioned device and a relay 30 fitted with captive screws. In addition, the establishment of a base according to the invention can be carried out manually, without using any tools, using a push in the direction of arrow 19 corresponding to a weak force of insertion.
