Description

L'invention concerne un support d'antenne hélicoïdale.The invention relates to a helical antenna support.

Elle concerne plus précisément une antenne interne d'un produit communiquant par radio, en particulier pour des produits de comptage, tels que des modules de télérelevé de compteurs de fluide ou d'électricité.It relates more specifically to an internal antenna of a product communicating over the radio, in particular for counting products, such as metering modules for meters of fluid or electricity.

L'antenne est soudée sur la carte électronique du produit et doit être correctement orientée pour s'accorder à la fréquence radio de fonctionnement.The antenna is soldered to the product's electronic board and must be properly oriented to match the operating radio frequency.

Or elle peut être déformée lors de son montage sur la carte électronique et le pas des spires, qui est un paramètre important de fonctionnement, peut également varier dans le temps et dégrader les performances du produit.Or it can be deformed when mounted on the electronic card and the pitch of the turns, which is an important parameter of operation, may also vary over time and degrade the performance of the product.

Il a donc déjà été envisagé de la consolider au moyen d'un support.It has already been envisaged to consolidate it by means of a support.

Un support d'antenne hélicoïdale est décrit dans le brevet 5 406 693.A helical antenna support is described in the patent 5,406,693.

Ce support est constitué de quatre éléments conformés en forme de croix et solidaires d'une base cylindrique, ces éléments étant des plaques rectangulaires et étant pourvus de fentes disposées à un pas précis sur leur bord externe. Des éléments en forme de coin sont disposés entre ces éléments et un fil conducteur est ainsi disposé dans les fentes et contre les coins pour former une antenne. Les coins sont ensuite enlevés par coulissement et l'antenne est ainsi formée et supportée par le support.This support consists of four elements shaped in the form of cross and integral with a cylindrical base, these elements being rectangular plates and being provided with slots arranged at a precise pitch on their outer edge. Wedge-shaped elements are disposed between these elements and a conductive wire is thus disposed in the slots and against the corners to form an antenna. The corners are then slid off and the antenna is thus formed and supported by the support.

Ce mode de support suppose une fabrication de l'antenne directement sur le support. Si l'on se procure une antenne déjà fabriquée en forme d'hélice, le support décrit dans ce brevet ne convient pas.This mode of support supposes a manufacture of the antenna directly on the support. If an antenna already manufactured in the form of a helix is obtained, the support described in this patent is not suitable.

En effet, sa mise en place dans les fentes du support suppose soit une déformation par écartement de l'antenne pour emboîter les spires dans les fentes respectives, soit un vissage par rotation de l'antenne sur les fentes.Indeed, its implementation in the slots of the support assumes either deformation by spacing the antenna to fit the turns in the respective slots, or screwing by rotation of the antenna on the slots.

Or ces deux modes de montage sont consommateurs de temps et complexes, et surtout sont susceptibles de dégradation de l'antenne qui est constituée d'un fil relativement fin.However, these two modes of assembly are time consuming and complex, and especially are susceptible to degradation of the antenna which is made of a relatively thin wire.

L'invention résout ce problème en proposant un support d'antenne hélicoïdale destiné au montage d'une antenne déjà fabriquée et assurant un maintien parfait des spires de l'antenne à un pas précis.The invention solves this problem by proposing a helical antenna support for mounting an antenna already manufactured and ensuring a perfect hold of the turns of the antenna at a specific step.

Pour ce faire, l'invention propose un support d'antenne hélicoïdale comportant au moins trois branches de support sensiblement rectangulaires également réparties autour d'une colonne centrale, la largeur de ces branches de support étant telle que leur bord externe est disposé sur un cylindre géométrique de section sensiblement égale à la section interne de l'antenne, caractérisé en ce qu'il comporte également au moins trois éléments de peignes comportant des fentes espacées d'un pas identique à celui des spires de l'antenne et destinées à être fixés sur chaque bord externe desdites branches de support, avec leur fentes tournées vers lesdites branches de support.To do this, the invention proposes a helical antenna support comprising at least three substantially rectangular support legs also distributed around a central column, the width of these support legs being such that their outer edge is disposed on a cylinder geometric section substantially equal to the internal section of the antenna, characterized in that it also comprises at least three comb elements having slots spaced a pitch identical to that of the turns of the antenna and intended to be fixed on each outer edge of said support legs, with their slots facing towards said support legs.

Grâce à l'invention, toute déformation et donc toute perte de fonctionnement de l'antenne sont évitées. Le montage de l'antenne sur une carte électronique ainsi que son orientation sont également facilités.Thanks to the invention, any deformation and therefore any loss of operation of the antenna are avoided. The mounting of the antenna on an electronic card and its orientation are also facilitated.

Selon un mode de réalisation préféré de l'invention, lesdits éléments de peigne sont conformées d'un profilé en U dont chaque branche du U comporte lesdites fentes et destinés à être emboîtés sur le bord externe de chaque branche du support.According to a preferred embodiment of the invention, said comb members are shaped of a U-shaped section each U-branch comprises said slots and intended to be fitted on the outer edge of each branch of the support.

Avantageusement, lesdits éléments de peigne comportent au moins un tenon d'encliquetage dans un orifice agencé sur le bord externe desdites branches de support.Advantageously, said comb elements comprise at least one locking pin in an orifice arranged on the edge outer of said support legs.

Lesdits éléments de peigne peuvent être reliées à chaque dite branche de support par une charnière.Said comb members may be connected to each said support leg by a hinge.

Lesdites branches comportent avantageusement une sur-largeur d'appui de la spire inférieure de l'antenne.Said branches advantageously comprise an extra width of support of the lower turn of the antenna.

Le support peut comporter un orifice de guidage de l'extrémité de ladite antenne destinée à être fixée sur une carte électronique.The support may comprise a guide orifice of the end of said antenna intended to be fixed on an electronic card.

L'invention est décrite ci-après plus en détail à l'aide de figures ne représentant que des modes de réalisation préférés de l'invention.The invention is described below in more detail with the aid of figures representing only preferred embodiments of the invention.

La figure 1 est une vue en perspective d'une antenne hélicoïdale montée sur un support conforme à l'invention.The figure 1 is a perspective view of a helical antenna mounted on a support according to the invention.

Les figures 2 à 5 illustrent les étapes de montage d'une antenne hélicoïdale sur un support conforme à l'invention.The Figures 2 to 5 illustrate the steps of mounting a helical antenna on a support according to the invention.

La figure 6 est une vue en perspective d'un support conforme à l'invention selon une variante de réalisation.The figure 6 is a perspective view of a support according to the invention according to an alternative embodiment.

Comme représenté sur la figure 1, l'invention concerne un support 1 d'antenne hélicoïdale 2, en matière plastique, comportant au moins trois branches de support 1A, 1B, 1C sensiblement rectangulaires également réparties autour d'une colonne centrale 1D , la largeur de ces branches de support étant telle que leur bord externe est disposé sur un cylindre géométrique de section sensiblement égale à la section interne de l'antenne 2.As shown on the figure 1 , the invention relates to a support 1 of helical antenna 2, made of plastic, comprising at least three support legs 1A, 1B, 1C substantially rectangular also distributed around a central column 1D, the width of these support branches being such that their outer edge is arranged on a geometric cylinder of section substantially equal to the internal section of the antenna 2.

Ce support 1 comporte également au moins trois éléments de peignes 2A, 2B , 2C, également en matière plastique, comportant des fentes espacées d'un pas identique à celui des spires de l'antenne 2 et destinées à être fixés sur chaque bord externe des branches de support 1A, 1B, 1C, avec leur fentes tournées vers les branches de support.This support 1 also comprises at least three comb elements 2A, 2B, 2C, also made of plastic, having slots spaced at a pitch identical to that of the turns of the antenna 2 and intended to be fixed on each outer edge of the support legs 1A, 1B, 1C, with their slots facing the support legs.

Une fois l'antenne 2 monté sur le support 1 comme illustré sur la figure 1, le support comporte un orifice de guidage 3 de l'extrémité 2A de l'antenne destinée à être fixée sur une carte électronique 4.Once the antenna 2 mounted on the support 1 as illustrated on the figure 1 , the support comprises a guide orifice 3 of the end 2A of the antenna intended to be fixed on an electronic card 4.

Les différentes pièces sont plus visibles sur les figures 2 à 5, qui illustrent les étapes de montage d'une antenne 2 sur un tel support.The different pieces are more visible on the Figures 2 to 5 , which illustrate the steps of mounting an antenna 2 on such a support.

Comme représenté sur la figure 2, l'antenne 2 est disposée sur ce support par emboîtement de ce dernier à l'intérieur de l'antenne, avec une orientation telle que l'extrémité 2A de l'antenne vienne s'introduire dans l'orifice 3 du support.As shown on the figure 2 , the antenna 2 is disposed on this support by interlocking the latter inside the antenna, with an orientation such that the end 2A of the antenna comes to be introduced into the orifice 3 of the support.

Les branches 1A, 1B, 1C, comportent avantageusement une sur-largeur 5A, 5B, 5D d'appui de la spire inférieure de l'antenne.The branches 1A, 1B, 1C, advantageously comprise an over-width 5A, 5B, 5D of support of the lower turn of the antenna.

Après cette première étape de montage, l'antenne 2 est dans la position représentée sur la figure 3.After this first mounting step, the antenna 2 is in the position shown on the figure 3 .

Les éléments de peigne 2A, 2B, 2C sont ensuite fixés sur chaque bord externe des branches de support 1A, 1B, 1C, comme illustré sur la figure 4.The comb members 2A, 2B, 2C are then attached to each outer edge of the support legs 1A, 1B, 1C, as shown in FIG. figure 4 .

Ces éléments de peigne 2A, 2B, 2C sont conformés d'un profilé en U dont chaque branche du U comporte les fentes 6 et destinés à être emboîtés sur le bord externe de chaque branche du support 1A, 1B, 1C. Les fentes 6 viennent recevoir les spires de l'antenne 2 qui sont ainsi maintenues en place.These comb members 2A, 2B, 2C are formed of a U-shaped section each branch of the U comprises the slots 6 and intended to be fitted on the outer edge of each leg of the support 1A, 1B, 1C. The slots 6 receive the turns of the antenna 2 which are thus held in place.

Pour leur fixation sur chaque bord externe des branches de support 1A, 1B, 1C, les éléments de peigne 2A, 2B, 2C comportent chacun au moins un tenon 7 d'encliquetage dans un orifice agencé sur le bord externe des branches de support. Les trois éléments de peigne ont une longueur identique et ils sont positionnés à des niveaux différents sur les branches de support 1A, 1B et 1C. Ils sont bloqués en position par encliquetage de chaque tenon 7 dans l'orifice correspondant du bord externe des branches de support.For fixing on each outer edge of the support legs 1A, 1B, 1C, the comb members 2A, 2B, 2C each comprise at least one pin 7 snap into an orifice arranged on the outer edge of the support legs. The three comb members have an identical length and are positioned at different levels on the support legs 1A, 1B and 1C. They are locked in position by snapping each peg 7 into the corresponding hole of the outer edge of the support legs.

L'antenne 2 ainsi complètement montée sur le support 1, comme illustrée sur la figure 5, peut être fixée sur une carte électronique 4 au moyen de pions de centrage et de positionnement 9, au nombre de quatre, insérés pour les uns dans la carte et posés sur celle-ci pour d'autres.The antenna 2 thus completely mounted on the support 1, as illustrated on the figure 5 , can be fixed on an electronic card 4 by means of centering and positioning pins 9, four in number, inserted for one into the card and placed thereon for others.

Selon une variante représentée sur la figure 6, les éléments de peigne 2A, 2B, 2C peuvent être reliées à chaque branche de support 1A, 1B, 1C, par une charnière, ici constitué d'une languette flexible 10.According to a variant represented on the figure 6 , the comb members 2A, 2B, 2C can be connected to each support leg 1A, 1B, 1C, by a hinge, here consisting of a flexible tongue 10.
