Description

Dispositif de commande ou de signalisation tel qu'un bouton-poussoir Control or signaling device such as a push button
La présente invention concerne un dispositif de commande ou de signalisation tel qu'un ensemble de bouton-poussoir.The present invention relates to a control or signaling device such as a push button assembly.
De tels dispositifs comportent d'une part un corps à engager dans un orifice d'une paroi de support, par exemple d'un panneau ou d'un pupitre, et d'autre part une embase qui porte de manière amovible au moins un bloc électrique, notamment un bloc de contacts, à l'aide de moyens d'assemblage associés à des faces d'assemblage réciproque et fréquemment constitués par des éléments d'encliquetage.Such devices comprise on the one hand a body to be engaged in an orifice of a support wall, for example of a panel or of a lectern, and on the other hand a base which removably carries at least one block electrical, in particular a contact block, using assembly means associated with reciprocal assembly faces and frequently constituted by snap-on elements.
Les dispositifs connus de ce type n'offrent pas toujours la rigidité d'assemblage souhaitée et il est souhaitable de les perfectionner pour permettre à un monteur d'engager et de fixer sans difficulté le bloc de contacts sous l'embase ; de même, il est souhaitable de lui permettre éventuellement d'empiler facilement, mais là encore avec une bonne rigidité, un autre bloc de contacts sous le précédent.Known devices of this type do not always offer the desired rigidity of assembly and it is desirable to improve them to allow an assembler to easily engage and fix the contact block under the base; similarly, it is desirable to allow it possibly to stack easily, but again with good rigidity, another block of contacts under the previous one.
L'invention a pour but de procurer au monteur une grande facilité d'assemblage d'un bloc de contacts sous une embase d'un dispositif de commande ou de signalisation électrique, de pair avec une bonne rigidité de l'assemblage ainsi obtenu.The object of the invention is to provide the assembler with great ease of assembly of a contact block under a base of an electrical control or signaling device, together with good rigidity of the assembly thus obtained.
Selon l'invention :According to the invention:
- le bloc électrique et l'embase comportent, à une extrémité de leurs faces d'assemblage réciproque, un bec rigide et un redan de forme complémentaire coopérant entre eux pour assurer le positionnement et le maintien du bloc,the electrical block and the base include, at one end of their reciprocal assembly faces, a rigid spout and a step of complementary shape cooperating with each other to ensure the positioning and the maintenance of the block,
- le bloc comporte, à l'autre extrémité de sa face d'assemblage à l'embase, un crochet sollicité par des moyens élastiques parallèlement à la face d'assemblage pour coopérer avec un logement d'accrochage ménagé dans l'embase.- The block comprises, at the other end of its face for assembly to the base, a hook urged by elastic means parallel to the assembly face to cooperate with a latching housing formed in the base.
Le crochet peut avantageusement être constitué par une pièce métallique en U dont les ailes sont sensiblement alignées avec les grandes parois latérales du bloc électrique. D'autre part, il peut être avantageux d'orienter dans le même sens le bec rigide et le crochet, ce qui diminue l'encombrement du bloc et en permet une pose plus intuitive, tandis que des éléments de forme coopérants peuvent avantageusement être prévus sur les faces d'assemblage de manière à éviter tout glissement du bloc par rapport à l'embase, consécutivement à un effort exercé sur le bloc électrique perpendiculairement à la paroi de support du dispositif.The hook can advantageously be constituted by a metal U-shaped piece whose wings are substantially aligned with the large side walls of the electrical block. On the other hand, it may be advantageous to orient the rigid spout and the hook in the same direction, which reduces the bulk of the block and allows it to be laid more intuitive, while cooperating elements can advantageously be provided on the assembly faces so as to avoid any sliding of the block relative to the base, following a force exerted on the electrical block perpendicular to the support wall of the device.
La description qui va être faite à présent d'un mode de réalisation de l'invention, en regard des dessins annexés, explicite les avantages et résultats de celle-ci.The description which will now be given of an embodiment of the invention, with reference to the appended drawings, explains the advantages and results of the latter.

Le dispositif de commande ou de signalisation électrique illustré sur les figures est un bouton-poussoir comportant un corps 10 muni d'une tête 11 et d'une partie tubulaire 12 d'axe X1 et de diamètre inférieur à la largeur de la tête. Celle-ci est posée avec éventuellement un joint et/ou une étiquette non représentés sur une face externe 13a d'une paroi mince de support 13, par exemple métallique, qui appartient à une enveloppe telle qu'un pupitre, une armoire,.. . La paroi 13 est orientée selon un plan S perpendiculaire à X1 et comprer un orifice 13b dans lequel s'engage avec jeu la partie tubulaire 12 du bouton-poussoir, cette partie logeant par exemple la queue mobile de poussée du bouton. Une embase 20 à contour général polygonal, de préférence rectangulaire, est associée au bouton-poussoir au revers de la paroi 13, c'est-à-dire du côté de la face interne 13c de la paroi 13, pour porter de manière amovible des blocs électπques détachables 30 tels que des blocs de contacts interrupteurs, des blocs de voyant ou des blocs auxiliaires. L'embase est mise en place sur la partie tubulaire 12 et en est rendue solidaire par des éléments de forme coopérant entre eux, par exemple par emboîtement ou encliquetage, pour empêcher l'extraction de l'embase dans la direction X1. L'embase 20 offre une ouverture centrale 21 (voir figure 2) pour le libre passage de la partie tubulaire 12 du bouton-poussoir et elle est d'autre part ancrée contre la face interne 13c de la paroi 13 au moyen d'un coulisseau d'accrochage 22 sollicité par une vis de manoeuvre non représentée. Un élément 14 du bouton poussoir, mobile selon la direction X1 , coopère avec un doigt d'actionnement propre au bloc électriqueThe electrical control or signaling device illustrated in the figures is a push button comprising a body 10 provided with a head 11 and with a tubular part 12 of axis X1 and of diameter less than the width of the head. This is posed possibly with a seal and / or a label not shown on an external face 13a of a thin support wall 13, for example metallic, which belongs to an envelope such as a desk, a cabinet, etc. . The wall 13 is oriented along a plane S perpendicular to X1 and includes an orifice 13b in which the tubular part 12 of the push button engages with play, this part accommodating, for example, the movable pushing tail of the button. A base 20 with a general polygonal outline, preferably rectangular, is associated with the push button on the reverse of the wall 13, that is to say on the side of the internal face 13c of the wall 13, for removably carrying detachable electrical blocks 30 such as switch contact blocks, indicator blocks or auxiliary blocks. The base is placed on the tubular part 12 and is made integral by form elements cooperating with each other, for example by interlocking or snap-fastening, to prevent the extraction of the base in the direction X1. The base 20 offers a central opening 21 (see FIG. 2) for the free passage of the tubular part 12 of the push button and it is on the other hand anchored against the internal face 13c of the wall 13 by means of a slide. attachment 22 urged by an operating screw not shown. An element 14 of the push button, movable in the direction X1, cooperates with an actuating finger specific to the electrical block
Le bloc de contacts 30 comporte un boîtier prismatique 31 en matière isolante présentant du côté de l'embase une face 32 d'assemblage a celle-ci, d'où émerge le doigt d'actionnement 31 a ; le boîtier présente du côté opposé une face de connexion 33 pour l'accès d'un outil, via des orifices 34a, 34b ménagés dans cette face 33, à des vis ou autres éléments de connexion 35 pour des conducteurs de câblage Les conducteurs peuvent en effet être introduits latéralement par des orifices 36a, 36b ménagés dans de petites faces latérales 37a, 37b du boîtier , celui-ci présente enfin de grandes faces latérales planes 38,39The contact block 30 comprises a prismatic housing 31 made of insulating material having on the side of the base a face 32 for assembly therewith, from which the actuating finger 31 a emerges; the housing has on the opposite side a connection face 33 for the access of a tool, via orifices 34a, 34b formed in this face 33, to screws or other connection elements 35 for wiring conductors The conductors can effect be introduced laterally through holes 36a, 36b formed in small side faces 37a, 37b of the housing, the latter finally has large flat side faces 38,39
L'embase 20 est en matière métallique ou plastique , elle est prévue pour porter plusieurs blocs de contacts 30, au nombre de trois ou plus, accolés côte à côte par leurs grandes faces latérales. Chaque bloc de contacts 30 présente sur sa face d'assemblage 32 qui est allongée et de forme générale rectangulaire et aux deux extrémités de celle-ci, c'est-à-dire vers ses petits côtés, un bec rigide 40 et un crochet 50 mobile selon la direction Y. L'embase 20 présente des joues de guidage 28a coopérant avec les grandes faces latérales 38,39 du bloc 30 pour faciliter l'engagement du bec dans une ouverture 24 de l'embase et des parois de guidage 28b délimitant latéralement l'ouverture et coopérant avec les facettes latérales du bec. Le bec rigide 40 possède une extrémité libre 40a s'éloignant du crochet 50 et il est orienté selon une direction Y qui est parallèle au plan S et aux grandes faces latérales du boîtier ; le bec 40 comprend une zone d'appui 41 sensiblement parallèle à S et coopérant avec un épaulement correspondant de retenue 23 ménagé avec une forme complémentaire de celle du bec dans l'ouverture 24 de l'embase.The base 20 is made of metallic or plastic material, it is designed to carry several contact blocks 30, three in number or more, joined side by side by their large lateral faces. Each contact block 30 has on its assembly face 32 which is elongated and of generally rectangular shape and at both ends thereof, that is to say towards its short sides, a rigid spout 40 and a hook 50 movable in direction Y. The base 20 has guide cheeks 28a cooperating with the large lateral faces 38, 39 of the block 30 to facilitate the engagement of the spout in an opening 24 of the base and of the guide walls 28b delimiting laterally the opening and cooperating with the lateral facets of the spout. The rigid spout 40 has a free end 40a moving away from the hook 50 and it is oriented in a direction Y which is parallel to the plane S and to the large lateral faces of the housing; the spout 40 comprises a support zone 41 substantially parallel to S and cooperating with a corresponding retaining shoulder 23 formed with a shape complementary to that of the spout in the opening 24 of the base.
Le crochet mobile 50 est orienté selon la même direction Y et dans le même sens pour coopérer avec un logement d'accrochage 25 prévu dans l'embase 20. Il comprend à cet effet à son extrémité libre 50a un bord oblique 51 qui coopère avec une face inclinée 26 du logement 25 L'inclinaison du bord 51 et de la face 26 autoπse un rattrapage de jeu , en outre, elle est telle que la partie repπse par le crochet 50 des efforts communiques par le poussoir du bouton au bloc de contacts 30 tend à repousser celui-ci vers la droite. Donc pour empêcher une éventuelle extraction du bloc de contacts hors de l'embase par glissement quand on exerce une pression sur le bouton-poussoir, le bloc 30 présente en saillie par rapport à sa face d'assemblage 32 au moins un ergot 32a, par exemple deux tels ergots, qui se logent dans au moins une forme en creux 27a prévue dans une face d'accouplement 27 de l'embase , il va de soi que l'on peut prévoir à la place des éléments 27a, 32a d'autres éléments de forme analogues agencés pour éviter le désengagement du bloc vis-à- vis de l'embase sous l'effet d'un glissement selon la direction Y. Le crochet 50 comprend d'autre part une zone oblique 52 qui coopère avec un rebord 27b de la face d'accouplement 27. Ceci permet le dégagement du crochet 50 par compression d'un ressort hélicoïdal 53 quand le crochet 50 s'applique contre la face d'accouplement 27 On peut remarquer que le bec 40 et le crochet 50 font saillie d'une hauteur comparable h par rapport à la face d'assemblage 32.The movable hook 50 is oriented in the same direction Y and in the same direction to cooperate with a latching housing 25 provided in the base 20. For this purpose it comprises at its free end 50a an oblique edge 51 which cooperates with a inclined face 26 of the housing 25 The inclination of the edge 51 and of the face 26 autoπse a backlash, in addition, it is such that the part repπse by the hook 50 of the forces communicated by the push button of the button to the contact block 30 tends to push it to the right. So to prevent possible extraction of the contact block from the base by sliding when a pressure is exerted on the push-button, the block 30 has projecting with respect to its assembly face 32 at least one lug 32a, by example two such pins, which are housed in at least one hollow shape 27a provided in a coupling face 27 of the base, it goes without saying that we can provide instead of elements 27a, 32a other elements of similar shape arranged to avoid disengagement of the block vis-à-vis the base under the effect of a sliding in the direction Y. The hook 50 also comprises an oblique zone 52 which cooperates with a flange 27b of the coupling face 27. This allows the hook 50 to be released by compression of a helical spring 53 when the hook 50 is applied against the coupling face 27 It can be noted that the spout 40 and the hook 50 are projection of a comparable height h with respect to the face of ass emblem 32.
Le crochet 50 se présente (voir figure 5) sous la forme d'une pièce métallique en U dont l'âme 54 est plate et dont les ailes 55,56 constituent les éléments d'accrochage dotés des bords obliques 51 et faces inclinées 52. II convient de noter que les ailes 55,56 sont avantageusement alignées ou sensiblement alignées avec les grandes parois latérales 38,39 du bloc et coopèrent avec des parois de guidage 29 prévues dans des dégagements latéraux 29a de l'embase. L'âme 54 est prolongée vers l'intérieur du bloc par une queue plate de guidage 54a qui est glissée dans une fente 60 prévue vers la face d'assemblage 32 du boîtier 31 et qui maintient latéralement le ressort de rappel 53 Le boîtier se compose de préférence d'un corps de boîtier 31a et d'un couvercle 31 b , la fente 60 est ménagée dans le corps de boîtier 31a elle est ouverte latéralement (perpendiculairement à la direction Y) en 61 et elle peut être fermée par l'assemblage du couvercle 31 b du boîtier sur ie corps 31 aThe hook 50 is presented (see FIG. 5) in the form of a metal U-shaped piece whose core 54 is flat and whose wings 55, 56 constitute the hooking elements provided with oblique edges 51 and inclined faces 52. It should be noted that the wings 55, 56 are advantageously aligned or substantially aligned with the large lateral walls 38, 39 of the block and cooperate with guide walls 29 provided in lateral clearances 29 a of the base. The core 54 is extended towards the inside of the block by a flat guide tail 54a which is slid into a slot 60 provided towards the assembly face 32 of the housing 31 and which laterally retains the return spring 53 The housing consists preferably a housing body 31a and a cover 31b, the slot 60 is formed in the housing body 31a it is open laterally (perpendicular to the direction Y) at 61 and it can be closed by assembling the cover 31b of the housing on the body 31a
La petite face latérale 37b du boîtier située du côté du crochet 50 comprend un pan oblique 62 situe entre deux éléments de paroi 63 de manière à offπr un passage incliné a un outil de manoeuvre du crochet 50 , la pointe de l'outil est guidée par les éléments de paroi 63 et coopère avec une ouverture 57 de l'âme 54 du crochet.The small lateral face 37b of the housing located on the side of the hook 50 comprises an oblique face 62 situated between two wall elements 63 so as to offer an inclined passage to a tool for operating the hook 50, the tip of the tool is guided by the wall elements 63 and cooperates with an opening 57 of the core 54 of the hook.
Du côté de sa face de connexion 33, le boîtier du bloc de contacts 30 présente des moyens de couplage avec un bloc sous-jacent. Ces moyens comprennent d'une part un épaulement plan 70 similaire à l'épaulement 23 de l'ouverture 24 de l'embase et d'autre part un logement d'accrochage 71 à face inclinée 72 similaire à la face inclinée 26 du logement 25 de l'embase. Il convient de remarquer que l'épaulement de retenue 70 et la face inclinée 72 sont ménages respectivement dans l'orifice 34a d'accès a une vis de connexion 35 et dans des dégagements 38a, 39a prévus dans les grandes faces latérales 38,39 du boîtier 31 Au moins un orifice 73 est prévu pour loger les ergots 32a du bloc sous-jacent On réalise de cette façon un empilage des blocs de contacts par des moyens très simples, qui néanmoins assurent une rigidité suffisante d'assemblage tout en étant situés dans le gabarit en largeur des blocs.On the side of its connection face 33, the housing of the contact block 30 has coupling means with an underlying block. These means comprise on the one hand a flat shoulder 70 similar to the shoulder 23 of the opening 24 of the base and on the other hand a hooking housing 71 with inclined face 72 similar to the inclined face 26 of the housing 25 of the base. It should be noted that the retaining shoulder 70 and the inclined face 72 are housed respectively in the orifice 34a for access to a connection screw 35 and in clearances 38a, 39a provided in the large lateral faces 38, 39 of the housing 31 At least one orifice 73 is provided for housing the lugs 32a of the underlying block. This is done by stacking the contact blocks by very simple means, which nevertheless ensure sufficient rigidity for assembly while being located in the width gauge of the blocks.
Il convient de remarquer que le bec rigide 40 a son extrémité libre 40a située à l'oppose du crochet 50 , il peut aussi avoir son extrémité libre disposée vers le crochet 50. La solution décrite a cependant l'avantage d'être moins encombrante et de permettre une pose plus intuitive du bloc de contacts dans l'embase. It should be noted that the rigid spout 40 has its free end 40a situated opposite the hook 50, it can also have its free end disposed towards the hook 50. The solution described however has the advantage of being less bulky and to allow a more intuitive installation of the contact block in the base.
