Description

Le domaine de l'invention est celui des systèmes d'adaptation entre une antenne et un poste émetteur et/ou récepteur de signaux radio-électriques. Plus précisément, la présente invention concerne un système d'adaptation permettant de raccorder une antenne quelconque à un tel poste. Le poste est par exemple un radiotéléphone, et la présente invention s'applique notamment aux radiotéléphones portatifs.The field of the invention is that of adaptation systems between an antenna and a radio transmitter and / or receiver station. More specifically, the present invention relates to an adaptation system making it possible to connect any antenna to such a station. The station is for example a radiotelephone, and the present invention applies in particular to portable radiotelephones.

Un radiotéléphone portatif se présente sous la forme d'un boîtier de taille réduite auquel est raccordée une antenne d'émission-réception de signaux radio-électriques. L'antenne comporte à l'une de ses extrémités une fiche coopérant avec un socle complémentaire fixé sur le boîtier. La fiche et le socle assurent à la fois un contact électrique et un maintien mécanique de l'antenne au boîtier et sont manuellement séparables pour permettre d'enlever l'antenne et faciliter ainsi le transport du poste et de l'antenne hors utilisation.A portable radiotelephone is in the form of a small-sized box to which is connected an antenna for transmitting and receiving radioelectric signals. The antenna comprises at one of its ends a plug cooperating with a complementary base fixed on the housing. The plug and the base provide both electrical contact and mechanical maintenance of the antenna to the housing and are manually separable to allow the antenna to be removed and thus facilitate the transport of the station and the antenna when not in use.

Lors de la conception d'un radiotéléphone, celui-ci est prévu pour être raccordé à une fiche d'antenne de type prédéterminé, c'est à dire que l'utilisateur devra choisir une antenne dont la fiche est adaptée au socle équipant le radiotéléphone.When designing a radiotelephone, it is intended to be connected to an antenna plug of predetermined type, that is to say that the user will have to choose an antenna whose plug is adapted to the base fitted to the radiotelephone. .

Différentes normes caractérisent de telles fiches et socles adaptées aux signaux de fréquence de l'ordre de 900 MHz et les prises le plus fréquemment employées sont de type SMA. Une prise de type SMA se compose d'une part d'un socle femelle, comportant un filetage formant masse et un conducteur interne formant âme, et d'autre part d'une fiche mâle, comportant un écrou apte à coopérer avec ce filetage et une âme. La fiche mâle est montée à l'extrémité d'une antenne et sa coopération avec le socle est assurée par vissage de l'écrou sur le filetage du socle.Different standards characterize such plugs and sockets adapted to frequency signals of the order of 900 MHz and the most frequently used sockets are of the SMA type. An SMA type socket consists on the one hand of a female base, comprising a thread forming a mass and an internal conductor forming a core, and on the other hand of a male plug, comprising a nut capable of cooperating with this thread and a soul. The male plug is mounted at the end of an antenna and its cooperation with the base is ensured by screwing the nut onto the thread of the base.

Le principal inconvénient de ce type de prise est qu'il ne permet pas un nombre de manoeuvres de l'antenne élevé et on observe rapidement une usure de la fiche et du socle, détériorant les qualités de la transmission hyperfréquence. En effet, un vissage d'un élément sur l'autre provoque des frottements à l'origine de l'usure précitée. Ces frottements se situent non seulement au niveau du contact de masse, mais également au niveau de l'âme et ont pour conséquence un usinage de ces contacts.The main drawback of this type of socket is that it does not allow a high number of operations of the antenna and wear and tear on the plug and the base are quickly observed, deteriorating the qualities of the microwave transmission. Indeed, a screwing of an element on the other causes friction causing the aforementioned wear. These frictions are located not only at the ground contact, but also at the core and result in machining of these contacts.

C'est pourquoi les fabricants ont mis au point des prises ne nécessitant pas de vissage d'un élément sur l'autre. Une prise permettant un nombre de manoeuvres élevé, couramment appelée "subclic", exploite l'élasticité d'une bague faisant partie de la fiche de l'antenne pour permettre la solidarisation de la fiche à un socle complémentaire. Le principal inconvénient de ce type de prise est qu'il est d'un prix de revient élevé et peu répandu.This is why manufacturers have developed sockets that do not require screwing of one element on the other. A socket allowing a high number of operations, commonly called "subclic", exploits the elasticity of a ring forming part of the antenna plug to allow the plug to be secured to a complementary base. The main disadvantage of this type of plug is that it is expensive and not widely used.

Par ailleurs, un inconvénient majeur des radiotéléphones existants est qu'il n'est pas possible, pour l'utilisateur, de choisir librement une antenne du commerce qui lui conviendrait, puisque celle-ci doit nécessairement présenter une fiche complémentaire du socle équipant son radiotéléphone.Furthermore, a major drawback of existing radiotelephones is that it is not possible, for the user, to freely choose a commercial antenna which would suit him, since the latter must necessarily present a complementary sheet of the base equipping his radiotelephone .

La présente invention a notamment pour objectif de pallier ces inconvénients.The present invention aims in particular to overcome these drawbacks.

Plus précisément, un premier objectif de l'invention est de fournir un système d'adaptation entre un poste d'émission-réception de signaux radio-électriques et une antenne permettant à l'utilisateur de monter n'importe quelle antenne du commerce sur son poste.More specifically, a first objective of the invention is to provide an adaptation system between a radio transmission / reception station and an antenna allowing the user to mount any commercial antenna on his post.

Un deuxième objectif de l'invention est de fournir un tel système qui permette d'effectuer un nombre de manoeuvres élevées de solidarisation-désolidarisation de l'antenne au poste.A second objective of the invention is to provide such a system which makes it possible to carry out a high number of maneuvers for securing-detaching the antenna from the station.

Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à un système d'adaptation entre une fiche d'antenne et un socle d'un poste émetteur et/ou récepteur de signaux radio-électriques comprenant un logement de réception d'un élément d'adaptation de la fiche d'antenne au socle, cet élément d'adaptation comprenant une extrémité de raccordement électrique et mécanique destinée à coopérer avec la fiche d'antenne et un moyen de raccordement au moins électrique destiné à coopérer avec le socle, ce socle étant compris à l'intérieur du logement de réception et entrant en contact électrique avec le moyen de raccordement par insertion axiale seulement de l'élément d'adaptation dans le logement, l'élément d'adaptation étant maintenu dans le logement par l'intermédiaire d'un moyen de maintien à actionnement manuel de manière à assurer une connexion électrique entre la fiche d'antenne et le socle lorsque la fiche d'antenne coopère avec l'extrémité de raccordement.These objectives, as well as others which will appear later, are achieved thanks to an adaptation system between an antenna plug and a base of a radio transmitter and / or receiver station comprising a housing for receiving an adaptation element from the antenna plug to the base, this adaptation element comprising an electrical and mechanical connection end intended to cooperate with the antenna plug and an at least electrical connection means intended to cooperate with the base, this base being included inside the reception housing and coming into electrical contact with the connection means by axial insertion only of the adapter element in the housing, the adapter element being held in the housing by means of a manually actuated holding means so as to ensure an electrical connection between the antenna plug and the base when the antenna plug cooperates with the connection end.

Ce système permet de monter n'importe quelle antenne sur un poste spécifique, le nombre de manoeuvres de solidarisation-désolidarisation étant élevé puisque le contact électrique entre le socle et le moyen de raccordement s'effectue par insertion axiale seulement de l'élément d'adaptation dans le logement prévu dans le poste. Il n'y a donc pas de mouvement de rotation à effectuer pour relier électriquement et mécaniquement l'antenne au poste.This system allows any antenna to be mounted on a specific station, the number of securing-decoupling operations being high since the electrical contact between the base and the connection means is effected by axial insertion only of the element adaptation in the housing provided in the post. There is therefore no rotational movement to be made to electrically and mechanically connect the antenna to the station.

Préférentiellement, le moyen de raccordement de l'élément d'adaptation est un moyen de raccordement axial qui pénètre axialement dans le socle et l'extrémité de raccordement électrique de l'élément d'adaptation est un raccordement à vis coopérant avec la fiche d'antenne, de telle sorte qu'une activation du moyen de maintien permette une extraction axiale simultanée de l'antenne et de l'élément d'adaptation.Preferably, the connection means of the adaptation element is an axial connection means which penetrates axially into the base and the electrical connection end of the adaptation element is a screw connection cooperating with the plug. antenna, so that activation of the holding means allows simultaneous axial extraction of the antenna and the adapter element.

Dans un mode de réalisation avantageux, le moyen de raccordement et le socle constituent une prise de type MCX.In an advantageous embodiment, the connection means and the base constitute an MCX type socket.

Préférentiellement, la fiche d'antenne et l'extrémité de raccordement constituent une prise de type SMA. Ce type de prise est celui le plus fréquemment utilisé pour le raccordement d'une antenne à un poste et l'utilisateur dispose ainsi d'un choix de type d'antenne important.Preferably, the antenna plug and the connection end constitute an SMA type socket. This guy socket is the most frequently used for connecting an antenna to a station and the user thus has a large choice of antenna type.

Avantageusement, le moyen de maintien activable manuellement est constitué par un mécanisme d'encliquetage assurant un verrouillage de l'élément d'adaptation dans le logement. On assure ainsi une solidarisation et une désolidarisation aisée du poste et de l'antenne.Advantageously, the manually activatable holding means is constituted by a latching mechanism ensuring locking of the adaptation element in the housing. This ensures easy attachment and separation of the station and the antenna.

Selon une application préférentielle, le poste est un radiotéléphone portatif.According to a preferred application, the set is a portable radiotelephone.

L'invention concerne également un élément d'adaptation et un poste prévus pour un tel système d'adaptation.The invention also relates to an adaptation element and a station provided for such an adaptation system.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante d'un mode de réalisation préférentiel, donné à titre illustratif et non limitatif, et des figures annexées dans lesquelles :

  • la figure 1 est une vue éclatée en coupe d'un mode de réalisation du système selon l'invention ;
  • la figure 2 est une vue en coupe des éléments de la figure 1 assemblés, une antenne étant fixée à l'extrémité de raccordement de l'élément d'adaptation.
Other characteristics and advantages of the invention will appear on reading the following description of a preferred embodiment, given by way of non-limiting illustration, and the appended figures in which:
  • Figure 1 is an exploded sectional view of an embodiment of the system according to the invention;
  • Figure 2 is a sectional view of the elements of Figure 1 assembled, an antenna being attached to the connection end of the adapter element.

Les figures 1 et 2 représentent des coupes d'un mode de réalisation préférentiel du système selon l'invention.Figures 1 and 2 show sections of a preferred embodiment of the system according to the invention.

Le système selon l'invention est adapté pour l'enfichage d'une antenne de type quelconque dans un boîtier d'un poste d'émission et/ou de réception de signaux radioélectriques. Il est constitué par un élément d'adaptation 10 comprenant une extrémité 11 de raccordement électrique et mécanique destinée à coopérer avec la fiche d'une antenne représentée à la figure 2. L'élément d'adaptation 10 comporte également un moyen de raccordement 12 électrique destiné à coopérer avec un socle 13 complémentaire situé au fond d'un logement 14 de réception ménagé dans le poste 15. Une demie-coque 16 du poste est représentée, cette demie-coque étant par exemple en matériau plastique.The system according to the invention is suitable for plugging an antenna of any type into a box of a radio transmitting and / or receiving station. It consists of an adapter element 10 comprising an end 11 of electrical and mechanical connection intended to cooperate with the plug of an antenna shown in FIG. 2. The adapter element 10 also includes an electrical connection means 12 intended to cooperate with a complementary base 13 located at the bottom of a receiving housing 14 formed in the station 15. A half-shell 16 of the station is shown, this half-shell being for example of plastic material.

Le logement 14 est par exemple cylindrique et comporte des parois intérieures 17 métalliques coopérant électriquement et mécaniquement avec le socle 13. Ce socle 13 comporte une partie centrale 18 métallique, de type femelle, destinée à entrer en contact électrique avec une âme 19 du moyen de raccordement 12 de l'élément d'adaptation 10, cette partie centrale 18 étant isolée, par un isolant 20, d'un conducteur de masse 21 destiné à entrer en contact électrique avec des dents 22 métalliques du moyen 12. Les dents 22 présentent une certaine élasticité assurant un maintien de l'élément d'adaptation 10 dans le logement 14, lorsque cet élément 10 est engagé dans ce logement 14. Comme il sera vu par la suite, ce maintien est surtout destiné à assurer un contact électrique optimal entre l'élément 10 et le socle 13.The housing 14 is for example cylindrical and has inner walls 17 of metal cooperating electrically and mechanically with the base 13. This base 13 has a central part 18 of metal, of female type, intended to come into electrical contact with a core 19 of the means of connection 12 of the adaptation element 10, this central part 18 being isolated, by an insulator 20, from a ground conductor 21 intended to come into electrical contact with metal teeth 22 of the means 12. The teeth 22 have a certain elasticity ensuring maintenance of the adaptation element 10 in the housing 14, when this element 10 is engaged in this housing 14. As will be seen later, this maintenance is mainly intended to ensure optimal electrical contact between the element 10 and the base 13.

Il est prévu que le contact électrique entre l'élément 10 et le socle 13 soit assuré par insertion axiale seulement de l'élément d'adaptation 10 dans le logement 14, c'est à dire qu'aucune rotation ne soit nécessaire pour établir ce contact électrique. On permet de ce fait un nombre de manoeuvres important, puisque l'usure des pièces est très inférieure à celle obtenue lorsqu'un mouvement de rotation assure le contact électrique et mécanique.It is expected that the electrical contact between the element 10 and the base 13 is ensured by axial insertion only of the adapter element 10 in the housing 14, that is to say that no rotation is necessary to establish this. electric contact. This allows a large number of operations, since the wear of the parts is much less than that obtained when a rotational movement provides electrical and mechanical contact.

L'élément d'adaptation 10 est maintenu dans le logement 14 par l'intermédiaire d'un moyen 23 de maintien à actionnement manuel qui assure une connexion électrique entre la fiche d'antenne et le socle lorsque cette fiche d'antenne coopère avec l'extrémité de raccordement.The adaptation element 10 is held in the housing 14 by means of a manually actuated holding means 23 which ensures an electrical connection between the antenna plug and the base when this antenna plug cooperates with the connection end.

Ce moyen de maintien est ici constitué par un verrou 24 à extrémité biseautée, permettant d'insérer l'élément 10 dans le logement 14 sans actionnement d'un levier 25. Le verrou coopère, comme représenté à la figure 2, avec une gorge 26 circulaire prévue dans l'élément d'adaptation 10. Un ressort à lame 27 solidaire du levier 25 permet de rappeler automatiquement le verrou 24 dans la position représentée, ce verrou effectuant un mouvement de translation selon un sens 28 lorsque l'utilisateur appuie sur la partie basse 29 du levier 25 ou alors engage l'élément de raccordement 10 dans le logement 14. L'axe de rotation du levier 25 est noté 30.This holding means is here constituted by a lock 24 with beveled end, making it possible to insert the element 10 in the housing 14 without actuation of a lever 25. The lock cooperates, as shown in FIG. 2, with a groove 26 circular provided in the adaptation element 10. A leaf spring 27 integral with the lever 25 makes it possible to automatically recall the lock 24 in the position shown, this lock performing a movement of translation in a direction 28 when the user presses on the lower part 29 of the lever 25 or then engages the connection element 10 in the housing 14. The axis of rotation of the lever 25 is noted 30.

Lorsque le moyen de maintien activable manuellement est constitué par un mécanisme d'encliquetage assurant un verrouillage de l'élément d'adaptation dans le logement du poste, comme celui représenté, les manoeuvres de solidarisation-désolidarisation de l'antenne, équipée de l'élément d'adaptation 10, sont aisées.When the manually activatable holding means is constituted by a latching mechanism ensuring a locking of the adaptation element in the housing of the station, like that shown, the maneuvers of securing-detaching of the antenna, equipped with the adaptation element 10 are easy.

Avantageusement, le moyen de raccordement 12 et le socle 13 constituent une prise de type MCX. Ce type de prise est bien connu dans le domaine du raccordement de câbles électriques, et permet un nombre de manoeuvres élevés (plus de 4000 manoeuvres).Advantageously, the connection means 12 and the base 13 constitute an MCX type socket. This type of plug is well known in the field of electrical cable connection, and allows a high number of operations (more than 4000 operations).

Comme représenté sur la figure 2, l'extrémité 11 de raccordement électrique et mécanique est destinée à coopérer avec la fiche 31 d'une antenne 35. Le mode de réalisation représenté correspond à une prise de type SMA, c'est à dire que la fiche d'antenne comporte un écrou 32 qui est vissé sur le pas de vis présenté par l'extrémité de raccordement 11 de l'élément d'adaptation 10. Ce type de prise qui ne permet pas un nombre de manoeuvres élevé est celui le plus répandu pour les antennes de radiotéléphones.As shown in Figure 2, the end 11 of electrical and mechanical connection is intended to cooperate with the plug 31 of an antenna 35. The embodiment shown corresponds to an SMA type socket, that is to say that the antenna plug comprises a nut 32 which is screwed onto the thread presented by the connection end 11 of the adapter element 10. This type of plug which does not allow a high number of operations is the most common for radiotelephone antennas.

De manière générale, il est intéressant d'utiliser d'une part un moyen de raccordement de l'élément d'adaptation de type axial qui pénètre axialement dans le socle et d'autre part une extrémité de raccordement électrique à vis qui coopère avec la fiche d'antenne, de telle sorte qu'une activation du moyen de maintien permette une extraction axiale simultanée de l'antenne et de l'élément d'adaptation.In general, it is advantageous to use on the one hand a means of connection of the axial type adaptation element which penetrates axially into the base and on the other hand an electrical connection end with a screw which cooperates with the antenna plug, so that activation of the holding means allows simultaneous axial extraction of the antenna and the adapter element.

Bien entendu, l'élément d'adaptation 10 peut comporter d'autres types d'extrémité de raccordement, adaptés à d'autres types de fiches d'antennes. L'extrémité de raccordement peut par exemple être de type subclic, à quart de tour,... De même, le socle 13 et le moyen de raccordement 12 peuvent être d'un autre type, l'essentiel étant que le contact électrique entre l'élément 10 et le socle 13 s'établisse à l'intérieur du logement 14 par simple insertion de l'élément 10 dans le logement. On peut par exemple utiliser des lames métalliques disposées de part et d'autre dans le logement 14, ces lames étant en contact électriques avec des pistes conductrices disposées sur l'élément d'adaptation 10. On observera cependant que les liaisons électriques réalisées doivent être de bonne qualité puisque les signaux électriques ont des fréquences élevées.Of course, the adaptation element 10 may include other types of connection end, adapted to other types of antenna plugs. The connection end can for example be of the subclic, quarter-type turn, ... Similarly, the base 13 and the connection means 12 may be of another type, the main thing being that the electrical contact between the element 10 and the base 13 is established inside of the housing 14 by simple insertion of the element 10 in the housing. It is for example possible to use metal blades arranged on either side in the housing 14, these blades being in electrical contact with conductive tracks disposed on the adaptation element 10. It will however be observed that the electrical connections made must be good quality since electrical signals have high frequencies.

L'âme 33 de la fiche d'antenne 31 pénètre dans un logement 34 (figure 1) métallique relié à l'âme 19 du moyen de raccordement 12. L'élément d'adaptation 10 est constitué par un noyau métallique 36 enrobé d'un isolant 37 lui-même entouré par un corps métallique 38 formant masse et constituant l'extérieur de l'élément. La longueur totale de cet élément est très réduite, de l'ordre de 15 mm.The core 33 of the antenna plug 31 enters a metal housing 34 (FIG. 1) connected to the core 19 of the connection means 12. The adaptation element 10 consists of a metal core 36 coated with an insulator 37 itself surrounded by a metal body 38 forming a mass and constituting the exterior of the element. The total length of this element is very reduced, of the order of 15 mm.

Lorsque les différents éléments constitutifs du système sont assemblés, une continuité électrique est obtenue entre l'âme et la masse de l'antenne d'une part et les parties 18 et 21 d'autre part, par l'intermédiaire de l'élément d'adaptation.When the various constituent elements of the system are assembled, electrical continuity is obtained between the core and the ground of the antenna on the one hand and the parts 18 and 21 on the other hand, via the element d 'adaptation.

Le fait de confiner l'élément d'adaptation 10 dans un logement et d'assurer son maintien dans ce logement permet de se dispenser des moyens de maintien classiques constitués par des mécanismes à vis.Confining the adaptation element 10 in a housing and ensuring its maintenance in this housing makes it possible to dispense with conventional holding means constituted by screw mechanisms.

La présente invention s'applique à tout type de poste émetteur et/ou récepteur de signaux radioélectriques, et notamment aux radiotéléphones de type portatif. Elle permet de fixer n'importe quelle antenne existante à un poste spécifique, la fixation réalisée permettant un nombre de manoeuvres élevé. Son application aux radiotéléphones portatifs est intéressante dans la mesure où leurs antennes sont fréquemment enlevées, pour faciliter leur transport hors utilisation.The present invention applies to any type of radio transmitter and / or receiver station, and in particular to portable type radiotelephones. It allows any existing antenna to be attached to a specific station, the attachment achieved allowing a high number of operations. Its application to portable radiotelephones is advantageous insofar as their antennas are frequently removed, to facilitate their transport when not in use.
