Abstract
Description
La présente invention se réfère à un radiomicrophone à emplois multiples, pourvu d'un circuit imprimé soutenu par un chassis extractible dans lequel tous les composants électriques sont associés au circuit lui-même. The present invention refers to a multipurpose radiomicrophone, provided with a printed circuit supported by an extractable chassis in which all the electrical components are associated with the circuit itself.
Les radiomicrophones actuellement connus comprennent, en général, un circuit imprimé enfermé dans un conteneur ; le circuit est connecté, par des conducteurs électriques, aux prises du microphone, de l'antenne et à un commutateur de commande, fixés directement à une paroi du conteneur lui-même. En outre, les radiomicrophones actuellement connus ne prévoient pas la possibilité de brancher le microphone directement à la prise du circuit imprimé, ou indirectement par un câble de rallonge pour permettre d'accrocher le microphone au cou ou aux vêtements au moyen d'accessoires appropriés. Currently known radio microphones include, in general, a printed circuit enclosed in a container; the circuit is connected, by electrical conductors, to the sockets of the microphone, the antenna and to a control switch, fixed directly to a wall of the container itself. In addition, currently known radiomicrophones do not provide the possibility of connecting the microphone directly to the socket on the printed circuit, or indirectly by an extension cable to allow the microphone to be hung on the neck or on clothing by means of appropriate accessories.
La présente invention a pour but de fournir un radiomicrophone à plusieurs emplois, apte à permettre l'insertion directe du microphone au circuit imprimé ou, indirectement, par un câble de rallonge. The present invention aims to provide a radiomicrophone for several uses, able to allow direct insertion of the microphone to the printed circuit or, indirectly, by an extension cable.
Selon un autre but, l'invention propose un radiomicrophone du genre précité, dans lequel tout le circuit imprimé est complètement extractible du conteneur qui le renferme, avec tous ses composants électriques associés ou branchés. Ainsi les opérations d'assemblage des composants électriques sur le circuit luim#e deviennent plus faciles, ainsi que les éventuelles interventions successives de réparation du radiomicrophone. According to another object, the invention provides a radiomicrophone of the aforementioned type, in which the entire printed circuit is completely extractable from the container which encloses it, with all of its associated or connected electrical components. Thus the assembly operations of the electrical components on the luim # e circuit become easier, as well as the possible successive interventions of repair of the radiomicrophone.
Selon sa forme générale, le microphone de l'invention comprend la combinaison suivante : un conteneur délimite par une paroi supé rieure, des parois périphériques latérales, et un couvercle inférieur crieur un chassis de support pour un circuit imprimé, extractible du conteneur, et des moyens de guidage et de blocage du chassis dans ce conteneur ; sur le côté du chassis de support du circuit imprimé, tourné vers la paroi supérieure du conteneur, sont fixés des composants du radiomicrophone tels que la prise du microphone ou, respectivement, le câble de rallonge, la prise de l'antenne et au moins un commutateur de commande, ces éléments étant accessibles et situés partiellement en saillie des ouvertures correspondantes dans la paroi supérieure du conteneur. According to its general form, the microphone of the invention comprises the following combination: a container delimited by an upper wall, lateral peripheral walls, and a lower screen cover a support frame for a printed circuit, extractable from the container, and means for guiding and locking the chassis in this container; on the side of the support frame of the printed circuit, facing the upper wall of the container, are fixed components of the radiomicrophone such as the microphone socket or, respectively, the extension cable, the antenna socket and at least one control switch, these elements being accessible and located partially projecting from the corresponding openings in the upper wall of the container.
Selon une autre caractéristique du radiomicrophone de l'invention, la pile d'alimentation du circuit électrique est soutenue directement par le chassis du circuit imprimé, au moyen d'un élément métallique de support fonctionnant également comme élément de blindage électromagnétique de protection. According to another characteristic of the radiomicrophone of the invention, the power supply stack of the electric circuit is supported directly by the chassis of the printed circuit, by means of a metallic support element also functioning as an electromagnetic shielding protection element.
Ces caractéristiques, et d'autres qui apparattront, sont illustrées pour un modèle non limitatif, par référence aux dessins cijoints où
Fig. 1 représente une vue en perspective du radiomicrophone ;
Fig. 2 représente une vue de la section longitudinale faite selon la ligne 2-2 de la fig. 3
Fig. 3 représente une section selon la ligne 3-3 de la fig. 2.These characteristics, and others which will appear, are illustrated for a nonlimiting model, with reference to the attached drawings where
Fig. 1 shows a perspective view of the radiomicrophone;
Fig. 2 shows a view of the longitudinal section taken along line 2-2 of FIG. 3
Fig. 3 represents a section along line 3-3 of FIG. 2.
Sur la figure 1 on peut voir une vue en perspective d'un radiomicrophone comprenant un conteneur 1 délimité, dans sa partie supérieure, par une paroi 2 et, périphériquement, par la paroi antérieure 3, la postérieure 4 et par les parois latérales 5 et 6 (fig. 2 et fig. 3). Dans sa partie inférieure le conteneur 1 est fermé par un couvercle 7 amovible s'appliquant par encliquetage. In FIG. 1 we can see a perspective view of a radiomicrophone comprising a container 1 delimited, in its upper part, by a wall 2 and, peripherally, by the front wall 3, the rear 4 and by the side walls 5 and 6 (fig. 2 and fig. 3). In its lower part the container 1 is closed by a removable cover 7 which is applied by snap-fastening.
En particulier, conformément aux indications des sections des figures 2 et 3, à l'intérieur du couvercle 7 se trouve installé un dispositif d'encliquetage 8, formé par un élément élastique en forme de U riveté ou fixé d'une façon différente en 10 sur le fond 11 du couvercle 7. Les deux bras latéraux 8' de l'élément d'encliquetage en forme de U, reposent sur les parois latérales 12 du couvercle 7 et sont élastiquement flexibles vers l'intérieur du couvercle pour dégager leurs extrémités à piton 13 d'un logement correspondant 14 prévu à l'intérieur sur chaque paroi latérale 5 et 6 du conteneur 1. In particular, in accordance with the indications in the sections of FIGS. 2 and 3, inside the cover 7 is installed a latching device 8, formed by an elastic element in the shape of a U riveted or fixed in a different way at 10 on the bottom 11 of the cover 7. The two lateral arms 8 ′ of the U-shaped latching element rest on the side walls 12 of the cover 7 and are elastically flexible towards the inside of the cover to release their ends at pin 13 of a corresponding housing 14 provided inside on each side wall 5 and 6 of the container 1.
Conformément à la vue en section de la fig. 2, chaque extrémité à piton 13 des bras élastiques 8' de l'élément d'encliquetage 8, se termine par une surface inclinée qui permet l'introduction par encliquetage dans le logement 14 par une simple poussée du couvercle en outre chaque bras 8', en position arrière par rapport à ses extrémités 13, présente une saillie 15 qui émerge partiellement d'une ouverture correspondante 16 de la paroi latérale 12 du couvercle pour permettre le dégagement de l'élément d'encliquetage 8, et par conséquent du couvercle 7 du corps du conteneur 1, par une simple poussée exercée de la main vers l'intérieur, dans le sens des flèches
17 indiquées à la fig. 2.According to the section view of FIG. 2, each end at peak 13 of the elastic arms 8 ′ of the latching element 8, ends in an inclined surface which allows snap-in insertion into the housing 14 by a simple push of the cover further each arm 8 ′ , in rear position relative to its ends 13, has a projection 15 which partially emerges from a corresponding opening 16 of the side wall 12 of the cover to allow the release of the latching element 8, and therefore of the cover 7 of the body of the container 1, by a simple push exerted by the hand inwards, in the direction of the arrows
17 indicated in fig. 2.
Toujours conformément aux indications de la fig. 2, le radiomicrophone est complété par un microphone 18 qui peut être branché directement à une prise 19 connectée au circuit imprimé du radiomicrophone ; selon une variante, on peut connecter un microphone 18' par un câble blindé de rallonge 20, cotte indiqué sur la figure 1. Le radiomicrophone pourra avoir ainsi un triple emploi, c'est à dire que le microphone 18 ou 18' peut être directement branché au circuit imprimé ou encore accroché au cou ou aux vêtements par des accessoires adéquats non indiqués sur les figures. Par 21 on a représenté l'antenne qui peut être branchée à sa prise 22 et, par le chiffre 23, on a indiqué l'ensemble d'un commutateur de commande alors que 23' représente le commutateur de sensibilité. Always according to the indications in fig. 2, the radiomicrophone is supplemented by a microphone 18 which can be connected directly to a socket 19 connected to the printed circuit of the radiomicrophone; according to a variant, a microphone 18 ′ can be connected by a shielded extension cable 20, with the coat indicated in FIG. 1. The radiomicrophone can thus have three uses, that is to say that the microphone 18 or 18 ′ can be directly connected to the printed circuit or hung on the neck or clothes by suitable accessories not indicated in the figures. By 21 there is shown the antenna which can be connected to its socket 22 and, by the number 23, the assembly of a control switch is indicated while 23 ′ represents the sensitivity switch.
Sur les figures 2 et 3, on a indiqué par 24 en général, un circuit imprimé du radiomicrophone. Ce circuit imprimé 24 est porté par un chassis métallique rectangulaire formé, dans ce cas, par une section de chassis supérieur 25, en forme de U renversé, et par une section de chassis inférieur 26, replie en forme de U, ayant une largeur légèrement inférieure à celle de la section du chassis supérieur pour être introduite dans cette dernière. In Figures 2 and 3, there is indicated by 24 in general, a printed circuit of the radiomicrophone. This printed circuit 24 is carried by a rectangular metal chassis formed, in this case, by an upper chassis section 25, in the shape of an inverted U, and by a lower chassis section 26, folded back in the shape of a U, having a width slightly lower than that of the upper chassis section to be introduced into the latter.
La section du chassis supérieur 25 présente de petites saillies latérales 27 qui, conjointement aux surfaces intérieures planes des parois latérales 5 et 6 du conteneur, définissent des moyens de guidage pour l'introduction et respectivement l'extraction du chassis portant le circuit imprimé ; les saillies 27 dudit chassis présentent en outre des trous taraudés pour le passage des vis 28 de blocage des parois 25, 26 à l'intérieur du conteneur 1. The section of the upper chassis 25 has small lateral projections 27 which, together with the flat interior surfaces of the side walls 5 and 6 of the container, define guide means for the introduction and respectively the extraction of the chassis carrying the printed circuit; the projections 27 of said chassis also have tapped holes for the passage of the screws 28 for locking the walls 25, 26 inside the container 1.
Il ressort des figures, et en particulier de la fig. 2, que le chassis 25, 26 ne porte pas seulement le circuit imprimé mais aussi les autres composants électriques du radiomicrophone ; on notera, en particulier, que sur le côté 25' du chassis tourné vers la paroi supérieure 2 du conteneur 1, sont fixés, par exemple au moyen de rivets, de bagues filetées ou autres, directement : la prise 19 pour le microphone, la prise 22 pour ltantenne, un commutateur de commande 23 et un indicateur lumineux 29 pouvant signaler si le radiomicrophone est en marche. Tous ces composants électriques ont une caractéristique commune à savoir qu'ils sont directement portés par le chassis 25, 26 et sont connectés électriquement au circuit imprimé 24 ; ils peuvent donc être introduits et sortis avec le circuit lui-m#me. Par conséquent, la partie supérieure 2 du conteneur 1 comporte des ouvertures spéciales 30, 31, 32 et 33 d'où émergent partiellement et deviennent donc accessibles, les composants électriques susvisés. Cette caractéristique se révèle extrêmement utile vu que, à la différence des radiomicrophones actuellement connus, elle permet de travailler librement sur le circuit imprimé à n'importe quel moment et pour n'importe quelle exigence, en l'enlevant simplement du conteneur 1 avec tous ses composants. It appears from the figures, and in particular from FIG. 2, that the frame 25, 26 not only carries the printed circuit but also the other electrical components of the radiomicrophone; it will be noted, in particular, that on the side 25 ′ of the chassis facing the upper wall 2 of the container 1, are fixed, for example by means of rivets, threaded rings or the like, directly: the socket 19 for the microphone, the socket 22 for the antenna, a control switch 23 and a light indicator 29 which can signal whether the radiomicrophone is on. All these electrical components have a common characteristic, namely that they are directly carried by the chassis 25, 26 and are electrically connected to the printed circuit 24; they can therefore be entered and taken out with the circuit itself. Consequently, the upper part 2 of the container 1 has special openings 30, 31, 32 and 33 from which partially emerge and therefore become accessible, the above-mentioned electrical components. This characteristic proves to be extremely useful since, unlike the currently known radiomicrophones, it allows to work freely on the printed circuit at any time and for any requirement, by simply removing it from the container 1 with all its components.
Une autre caractéristique du microphone selon l'invention a trait au support de la pile d'alimentation 34 du circuit électrique. Another characteristic of the microphone according to the invention relates to the support of the supply battery 34 of the electrical circuit.
En effet, comme on le voit sur la figure 2, la pile 34 est tenue par un élément de support 35 formé par une feuille métallique repliée en forme de U et fixée par son extrémité à la partie inférieure 26' de la section du chassis 26 du support du circuit imprimé ; en donnant aux deux parois latérales de l'élément 35 la juste inclinaison ou la convergence nécessaire, la pile 34 est tenue tout simplement par la pression élastique exercée par les susdites parois convergentes. In fact, as can be seen in FIG. 2, the stack 34 is held by a support element 35 formed by a metal sheet folded in the shape of a U and fixed by its end to the lower part 26 ′ of the section of the chassis 26 support of the printed circuit; by giving the two side walls of the element 35 the correct inclination or the necessary convergence, the stack 34 is held simply by the elastic pressure exerted by the above-mentioned converging walls.
Conformément aux indications de la section de la fig. 2 l'élément 35 de support de la pile 4 se prolonge sensiblement sur toute la longueur et la largeur de la pile 34 ; de -cette façon, le support de la pile fournit -également un blindage électrique et magnétique approprié -en protégeant le circuit imprimé du radiomicrophone de toute interférence possible avec la source d'alimentation. As indicated in the section in fig. 2 the element 35 for supporting the battery 4 extends substantially over the entire length and width of the battery 34; in this way, the battery holder also provides an appropriate electrical and magnetic shielding by protecting the printed circuit of the radiomicrophone from any possible interference with the power source.
