Thus the number of supports needed in telephone assembly are reduced. ADVANTAGE - Reduced manufacturing costs due to integrated housing.

Description

Appareil électronique à touches et afficheur associés
La présente invention se rapporte à un appareil électronique à touches et afficheur associés, notamment du type poste ou terminal téléphonique
Cet appareil qui est montré en figure 1 sans combiné, présente une face avant 1 au moins approximativement plane qui est légèrement inclinée par rapport à l'horizontale, lorsque le poste est posé.Electronic device with keys and associated display
The present invention relates to an electronic device with associated keys and display, in particular of the post or telephone terminal type.
This device which is shown in Figure 1 without a handset, has a front face 1 at least approximately flat which is slightly inclined relative to the horizontal, when the station is placed.

Cette face avant est garnie de diverses touches parmi lesquelles des touches de numérotation 2, et deux rangées de touches 3 par exemple de fonction ou de prise de ligne, qui sont placées de part et d'autre d'un afficheur 4, d'allure longiligne. cet afficheur permet par exemple d'afficher des informations diverses, notamment des pictogrammes représentatifs de l'état des lignes ou des fonctions qui sont associées aux touches voisines.This front face is furnished with various keys, including dialing keys 2, and two rows of keys 3, for example of function or line seizure, which are placed on either side of a display 4, having the appearance slender. this display allows for example to display various information, in particular pictograms representative of the state of the lines or of the functions which are associated with the neighboring keys.

Dans la réalisation présentée, est aussi figurée un boîtier 5 qui est muni d'un autre afficheur 8 associé à d'autres touches de fonction 6 ou 7.In the embodiment presented, there is also shown a box 5 which is provided with another display 8 associated with other function keys 6 or 7.

Pour des raisons d'économie de fabrication, les nombreuses touches 3, associées à l'afficheur 4, sont directement montées en grappe, sans être détachées une à une de leur grappe en matière plastique, qui est classiquement obtenue maintenue dans un cadre de support, en sortie de moule de fabrication.For reasons of economy of manufacture, the numerous keys 3, associated with the display 4, are directly mounted in a cluster, without being detached one by one from their plastic cluster, which is conventionally obtained maintained in a support frame. , leaving the manufacturing mold.

Il est prévu de plus: une pièce de passage et de guidage des touches non dégrappées, ainsi que de contention de l'afficheur 4 proprement dit et d'un premier flanc d'un connecteur élastomère, d'allure longiligne, chargé de réaliser l'interconnexion des pattes conductrices de l'afficheur avec une carte électronique, dite principale, que contient l'appareil; une pièce de calage pour un second flanc du connecteur élastomère qui est à l'opposé du premier flanc; une pièce de calage de la-face libre inférieure de l'afficheur.It is further provided: a passage and guide part for the non-unclipped keys, as well as for holding the display 4 proper and a first side of an elastomeric connector, of slender appearance, responsible for producing the interconnection of the conductive tabs of the display with an electronic card, called the main card, which the device contains; a wedging piece for a second side of the elastomeric connector which is opposite the first side; a wedging piece of the lower free face of the display.

Un tel assemblage est relativement complexe, délicat à monter et donc plus coûteux que souhaité dans le cas d'appareils de grande diffusion, tels que notamment des postes téléphoniques.Such an assembly is relatively complex, delicate to assemble and therefore more expensive than desired in the case of mass-market devices, such as in particular telephone sets.

L'invention concerne donc un appareil électronique dont une face, dite avant, comporte au moins un afficheur auquel sont associées des touches, telles que des touches de fonction ou de prise de ligne, elles aussi disposées sur cette face avant au voisinage de l'afficheur.The invention therefore relates to an electronic device, one face of which, called the front, comprises at least one display with which keys are associated, such as function or line pick-up keys, which are also arranged on this front face in the vicinity of the display.

Selon une caractéristique de cette invention: ces touches sont montées en grappe avec leur cadre de support de moulage, telle qu'en sortie de fabrication au moule, ce cadre de support comporte une traverse de calage pour au moins un des deux flancs d'un connecteur longiligne d'interconnexion de l'afficheur avec une carte électronique de l'appareil; ce cadre de support comporte aussi une ou plusieurs pattes de maintien de l'afficheur dans l'appareil, les dites pattes étant prévu pour venir en appui contre une face dite inférieure dudit afficheur.According to a characteristic of this invention: these keys are mounted in a cluster with their molding support frame, such that at the end of manufacturing in the mold, this support frame comprises a wedge crosspiece for at least one of the two sides of a elongated connector for interconnecting the display with an electronic card of the device; this support frame also includes one or more tabs for holding the display in the device, said tabs being designed to bear against a so-called lower face of said display.

De la sorte le cadre de support, en matière plastique qui constitue l'ossature de la grappe de touches, assure en outre des fonctions auxiliaires de calage et maintien d'au moins un des deux flancs du connecteur d'afficheur et de cet afficheur, ce qui permet notamment de faire l'économie des deux pièces de calage autrement nécessaires.In this way the support frame, made of plastic which constitutes the framework of the cluster of keys, also provides auxiliary functions for wedging and maintaining at least one of the two sides of the display connector and of this display, which allows in particular to save the two wedging pieces otherwise necessary.

L'invention, ses caractéristiques et ses avantages sont précisés dans la description qui suit en liaison avec les figures répertoriées ci-dessous.The invention, its characteristics and its advantages are explained in the following description in conjunction with the figures listed below.

La figure 1 présente une vue en perspective schématique d'un appareil électronique de type poste téléphonique.Figure 1 shows a schematic perspective view of an electronic device of the telephone set type.

Les figures 2 et 3 présentent respectivement une vue en perspective éclatée et une vue en coupe éclatée des pièces comprises entre la face avant d'un poste selon la figure 1 et la carte électronique, dite principale, de ce poste qui n'est représentée que sur les figures 3 et 4.Figures 2 and 3 respectively show an exploded perspective view and an exploded sectional view of the parts between the front face of a station according to Figure 1 and the electronic card, called main, of this station which is only shown in Figures 3 and 4.

La figure 4 présente une vue en coupe de l'assemblage constitué par les pièces montrées sur les figures 2, 3, après montage.Figure 4 shows a sectional view of the assembly consisting of the parts shown in Figures 2, 3, after assembly.

Sur les figures 2 à 4, la face avant 1 du poste est représentée retournée, ce qui est la position de montage en usine, alors qu'elle est à contrario montrée à l'endroit en figure 1. De même la carte électronique, dite principale, 9 présentée en haut sur les figures 3 et 4 est normalement placée en bas du poste lorsque le poste est repose-sur un support.In FIGS. 2 to 4, the front face 1 of the station is shown turned upside down, which is the factory mounting position, whereas it is instead shown in the right place in FIG. 1. Similarly, the electronic card, called main, 9 presented at the top in Figures 3 and 4 is normally placed at the bottom of the station when the station is resting on a support.

Pour suivre l'ordre réel des éléments, la description commencera par la carte principale 9 et ira vers la face avant 1.To follow the real order of the elements, the description will start with the main card 9 and go towards the front face 1.

Sur le carte principale 9, de type circuit imprimé, sont classiquement plaquées des bandes élastomères 10, îîqui comportent chacune une rangée de petites cavités tronconiques 12. Au fond de chacune de ces cavités est placée une pastille 13 en matériau conducteur électrique, tel du carbone.On the main card 9, of the printed circuit type, are conventionally plated elastomeric strips 10, which each comprise a row of small frustoconical cavities 12. At the bottom of each of these cavities is a pad 13 made of electrically conductive material, such as carbon .

En appuyant, à l'aide d'une touche en matière plastique 3, sur une de ces cavités, on aplatit celle-ci et la pastille 13 qu'elle contient vient s'appuyer sur le circuit imprimé de la carte 9, réalisant le contact électrique souhaité.By pressing, using a plastic button 3, on one of these cavities, it is flattened and the patch 13 which it contains comes to rest on the printed circuit of the card 9, achieving the electrical contact desired.

Les touches 3 sont classiquement laissées solidaires du cadre 14 avec lequel elles sortent du moule, lors de leur fabrication.The keys 3 are conventionally left integral with the frame 14 with which they leave the mold, during their manufacture.

L'afficheur 4 a classiquement des pattes de connexion 15 électriquement reliées au circuit imprimé 9 par un connecteur élastomère, plat, parallélépipèdique, d'allure longiligne, qui est positionné sur tranche, étant traversé de multiples lamelles conductrices transversales 17, usuellement en carbone, pour assurer les liaisons électriques souhaitées. The display 4 conventionally has connection tabs 15 electrically connected to the printed circuit 9 by an elastomeric connector, flat, parallelepiped, with a slender appearance, which is positioned on edge, being traversed by multiple transverse conductive strips 17, usually made of carbon, to ensure the desired electrical connections.

Une pièce en matière plastique 18 est prévue et conformée pour - livrer passage aux touches 3 de la grappe que solidarise le cadre 14, en guidant ces touches au moyen de lumières 19 correspondantes en nombre et dimensions; - recevoir l'afficheur 4 dans un berceau central 20, dimensionné et largement ajouré à cet effet; - positionner les bandes élastomères 10, 11 grâce à des picots 21, complémentaires d'orifices 22 de ces bandes; - presser les bandes élastomères 10, 11 et la tranche inférieure 24 du connecteur élastomère 16 contre le circuit imprimé de la carte 9.A plastic part 18 is provided and shaped to - allow passage to the keys 3 of the cluster that secures the frame 14, by guiding these keys by means of lights 19 corresponding in number and dimensions; - receive the display 4 in a central cradle 20, dimensioned and largely perforated for this purpose; - Position the elastomeric bands 10, 11 by means of pins 21, complementary to orifices 22 of these bands; - press the elastomer strips 10, 11 and the lower edge 24 of the elastomer connector 16 against the printed circuit of the card 9.

Au montage, cette pièce 18 vient se poser et s'encastrer sur une pièce en matière plastique 25 qui forme l'ossature de la face avant 1. Sur cette pièce 25 est fixée par enclipsage une vitre 26 de couverture d'afficheur, portée par la face avant 1, ainsi qu'un support de vitre 27 qui est garni de lumières 28 pour le passage des touches 3, ces lumières s'alignant avec les lumières 19 de la pièce 18 et avec des lumières 29 correspondantes de l'ossature 25.During assembly, this part 18 comes to rest and is embedded on a plastic part 25 which forms the framework of the front face 1. On this part 25 is fixed by clipping a window 26 of display cover, carried by the front face 1, as well as a window support 27 which is furnished with lights 28 for the passage of the keys 3, these lights aligning with the lights 19 of the part 18 and with corresponding lights 29 of the framework 25 .

Conformément à 1 invention, le cadre 14 qui porte la grappe de touches 3 comporte aussi deux traverses longitudinales 30 et 31.According to the invention, the frame 14 which carries the cluster of keys 3 also comprises two longitudinal crosspieces 30 and 31.

La traverse 30 vient latéralement caler le connecteur élastomère 16 en appuyant sur son flanc 33, la traverse 31 porte deux pattes latérales 32, en forme de L, qui viennent soutenir la face libre, dit inférieure, 34 de l'afficheur 4 pour le maintenir et le caler.The cross member 30 comes to wedge the elastomeric connector 16 laterally by pressing on its side 33, the cross member 31 carries two lateral legs 32, in the shape of an L, which come to support the free, so-called lower, face 34 of the display 4 to maintain it and wedge it.

L'ossature 14 de la grappe de touches 3 permet donc d'assurer ici le calage du flanc gauche du connecteur élastomère 16 ainsi que le soutien et le calage de l'afficheur 4, sans qu'il soit nécessaire de recourir à des pièce supplémentaires en ce but.The framework 14 of the key cluster 3 therefore makes it possible here to wedge the left flank of the elastomeric connector 16 as well as support and wedge the display 4, without the need for additional parts for this purpose.

L'invention ne doit pas être considérée comme limitée à l'exemple de réalisation présenté, en particulier en ce qui concerne la forme à donner aux pattes 32. The invention should not be considered as limited to the embodiment shown, in particular as regards the shape to be given to the legs 32.
