Description

L'invention concerne un agencement gyromagnétique comprenant un boítier enfermant un dispositif gyromagnétique, à verrouillage par un couvercle et pourvu d'ouvertures latérales de passage des pattes de connexion extérieures d'une âme centrale de transport d'énergie.The invention relates to a gyromagnetic arrangement. comprising a housing enclosing a device gyromagnetic, locked by a cover and provided lateral openings for the passage of the connection lugs exterior of a central energy transport core.

On connaít des agencements gyromagnétiques dont les boítiers sont obtenus par usinage conventionnel dans un bloc de métal ou en technologie de moulage par injection de métaux magnétiques. Le verrouillage se fait en général soit par le vissage d'un couvercle dans un corps cylindrique de boítier, soit par repoussage du métal du corps sur son couvercle.We know gyromagnetic arrangements whose housings are obtained by conventional machining in a metal block or injection molding technology of magnetic metals. Locking is generally done either by screwing a cover into a body cylindrical case, either by pushing back the metal of the body on its cover.

Les techniques connues de réalisation des boítiers ont pour inconvénients majeurs que leurs coûts de fabrication sont importants et leurs temps de réalisation trop longs.Known techniques for making housings have the major disadvantages that their costs of manufacturing are important and their completion times too long.

La présente invention a pour but de proposer un agencement gyromagnétique du type décrit plus haut, qui pallie les inconvénients qui viennent d'être énoncés.The object of the present invention is to provide a gyromagnetic arrangement of the type described above, which overcomes the disadvantages which have just been stated.

Pour atteindre ce but, le corps de boítier et le couvercle sont réalisés par emboutissage et le couvercle comporte un rebord cylindrique pourvu d'un filetage interne coopérant avec un filetage externe du corps de boítier.To achieve this goal, the housing body and the cover are made by stamping and the cover has a cylindrical rim with a thread internal cooperating with an external thread of the body housing.

Selon une caractéristique de l'invention, l'agencement gyromagnétique comporte un dispositif de maintien des éléments internes aussi bien lors du montage que lors de l'utilisation de l'agencement.According to a characteristic of the invention, the gyromagnetic arrangement includes a device for maintenance of internal elements as well during assembly than when using the layout.

Comme il ressort des figures, un agencement gyromagnétique selon l'invention comporte essentiellement un boítier métallique 1, de forme cylindrique, et un dispositif gyromagnétique 2 enfermé dans le boítier et susceptible d'être relié par des rubans de connexion 3 à des circuits extérieurs non représentés.As can be seen from the figures, an arrangement gyromagnetic according to the invention essentially comprises a metal case 1, of cylindrical shape, and a gyromagnetic device 2 enclosed in the housing and likely to be connected by connection tapes 3 to external circuits not shown.

En se référant notamment à la figure 1, on constate que le boítier 1 comporte un corps de boítier cylindrique 5 intégré à une semelle 6 et un couvercle 7 qui comporte une rebord annulaire 8 s'étendant perpendiculairement d'une face de base plane 9. La face cylindrique interne du rebord annulaire 8 du couvercle 7 est pourvue d'un filetage interne 11 et la portion supérieure de la face périphérique extérieure du corps de boítier 5 porte un filetage extérieur 12 permettant la fixation par vissage du couvercle 7 sur le corps de boítier 5. Ce dernier est pourvu de trois ouvertures latérales 13 réparties de façon angulairement équidistantes autour de l'axe du boítier (figure 3). Le corps de boítier et le couvercle sont avantageusement réalisés par emboutissage.Referring in particular to Figure 1, we see that the housing 1 comprises a cylindrical housing body 5 integrated with a sole 6 and a cover 7 which comprises an annular rim 8 extending perpendicularly a flat base face 9. The internal cylindrical face of the annular rim 8 of the cover 7 is provided with a internal thread 11 and the upper portion of the face outer device of the housing body 5 carries a external thread 12 allowing fixing by screwing cover 7 on the housing body 5. The latter is provided with three lateral openings 13 distributed from angularly equidistant around the axis of the housing (Figure 3). The housing body and the cover are advantageously made by stamping.

Le dispositif gyromagnétique 2 comporte essentiellement, de façon connue en soi, une âme centrale métallique 15 terminée par trois rubans de connexions extérieures 3, en forme de pattes, dont chacune s'étend à travers une ouverture d'accès 13 et, de chaque côté de l'âme centrale, de l'intérieur vers l'extérieur, un disque 17 en un matériau gyromagnétique tel qu'un ferrite, un disque en un matériau magnétique 18 et un aimant 19. Entre le disque magnétique 18 et le disque en ferrite 17 est interposé chaque fois un plan de masse métallique 20. Comme on le voit sur les figures 13 et 14, le plan de masse 20 supérieure qui est réalisé en laiton comporte, à sa périphérie, des pattes 22 qui sont déformées lors de l'assemblage du dispositif de façon à venir en contact pressé contre la face interne du corps de boítier. Comme on le voit sur la figure 14, les pattes 23 du plan de masse inférieur 21 sont réalisées sous forme de peigne pour avoir une meilleure flexibilité.The gyromagnetic device 2 comprises essentially, in a manner known per se, a central soul metallic 15 terminated by three connection tapes external 3, in the form of legs, each of which extends to through an access opening 13 and, on each side of the central soul, from the inside to the outside, a disc 17 made of a gyromagnetic material such as a ferrite, a disc of magnetic material 18 and a magnet 19. Between the magnetic disc 18 and the disc in ferrite 17 is interposed each time a ground plane metallic 20. As seen in Figures 13 and 14, the upper ground plane 20 which is made of brass has, at its periphery, tabs 22 which are deformed during assembly of the device so as to come into pressed contact against the internal face of the body of housing. As seen in Figure 14, the legs 23 of the lower ground plane 21 are produced under comb shape for better flexibility.

Etant donné que, les composants du dispositif gyromagnétique 2 enfermé dans le boítier 1, doivent être maintenus en place aussi bien lors du montage qu'ultérieurement lors de l'utilisation, l'agencement est pourvu, selon une caractéristique essentielle de l'invention, d'un organe de maintien 24 dont deux modes de réalisation sont représentées sur les figures respectivement 5 à 7 et 8 à 10. Cet organe de maintien 24 a pour fonctions d'isoler l'âme centrale 15 de la masse du corps du boítier, de maintenir l'âme centrale lors de la rotation et le verrouillage du couvercle, et, enfin, de centrer les pièces internes situées sous l'âme.Since the components of the device gyromagnetic 2 enclosed in the housing 1, must be held in place as well during assembly that later during use, the arrangement is provided, according to an essential characteristic of the invention, a holding member 24 including two modes are shown in the figures 5 to 7 and 8 to 10 respectively. This holding member 24 has the function of isolating the central core 15 from the mass of the body of the case, to maintain the central core during rotation and locking of the cover, and finally to center the internal parts located under the core.

A cette fin, le mode de réalisation selon les figures 5 à 7 qui équipent l'agencement gyromagnétique représenté sur les figures 1 et 2, comporte essentiellement une partie annulaire 25 destinée à être disposée coaxialement autour de la partie inférieure du corps de boítier, en contact avec la surface extérieure de celui-ci et, au niveau de chaque ouverture latérale d'accès 13 une patte de centrage 26 des pièces internes, qui s'étend à travers l'ouverture 13 et comporte une surface frontale arquée de centrage 27 dont le rayon de courbure correspond au rayon de courbure de la périphérie des pièces internes à maintenir. Le centreur 24 réalisé en un matériau isolant présentant de bonnes propriétés diélectriques aux fréquences micro-ondes. Au niveau de l'ouverture 13, la partie annulaire 25 comporte un élément formant rampe 29 qui fait saillie vers l'extérieur et fait la transition entre le plan supérieur de la patte de centrage 27 et la face inférieure de la semelle 6 à laquelle le boítier est intégré. Comme le montrent les figures 1 et 2, chaque patte de centrage 27 et chaque rampe 29 constituent un dispositif de support et de guidage d'un ruban de connexion 3 de l'âme centrale de l'agencement gyromagnétique selon l'invention en amenant ce ruban du plan qu'occupe l'âme centrale à l'intérieur du boítier et qui correspond à la surface supérieure des pattes de centrage 26 à la face inférieure 30 de la semelle en passant par une fente appropriée 31 pratiquée dans celle-ci. Pour assurer cette transition, la rampe 29 comporte, au niveau de son extrémité libre, une marche 32 qui correspond à l'épaisseur de la semelle 36. On constate en outre que la surface supérieure de la partie annulaire 25 comporte deux ergots 33 de guidage latéral et de centrage du ruban de connexion 3. Ainsi l'âme centrale qui constitue le composant interne le plus sensible est parfaitement maintenu dans l'agencement selon l'invention.To this end, the embodiment according to the Figures 5 to 7 which equip the gyromagnetic arrangement shown in Figures 1 and 2, includes essentially an annular part 25 intended to be arranged coaxially around the bottom of the housing body, in contact with the outer surface of it and at each side opening access 13 a centering tab 26 of the internal parts, which extends through the opening 13 and has a arcuate centering front surface 27 whose radius of curvature corresponds to the radius of curvature of the periphery internal parts to maintain. The centering device 24 produced made of an insulating material with good properties dielectric at microwave frequencies. At the level of the opening 13, the annular part 25 has a ramp element 29 which projects towards the exterior and makes the transition from the upper plane of the centering lug 27 and the underside of the sole 6 in which the housing is integrated. As the show Figures 1 and 2, each centering tab 27 and each ramp 29 constitute a support device and guiding a connecting strip 3 of the central core of the gyromagnetic arrangement according to the invention in bringing this ribbon from the plane that the central soul occupies to the inside of the case and which corresponds to the surface upper centering tabs 26 on the underside 30 from the sole passing through a suitable slot 31 practiced in it. To ensure this transition, the ramp 29 comprises, at its free end, a step 32 which corresponds to the thickness of the sole 36. It can also be seen that the upper surface of the annular part 25 has two guide pins 33 lateral and centering of the connection ribbon 3. Thus the central core which constitutes the most internal component sensitive is perfectly maintained in the layout according to the invention.

Les figures 8 à 10 montrent un autre mode de réalisation de l'organe de maintien. Dans ce mode, la partie annulaire désignée par la référence 35, comme auparavant de section transversale rectangulaire, est disposée à l'intérieur du boítier, au fond de celui-ci et comporte, associée à chaque ouverture de boítier 13, une patte en saillie extérieure 36 de guidage du ruban de connexion correspondant 3. Une partie 37 de la rampe repose sur la surface supérieure de la partie annulaire 35 et porte à son extrémité extérieure deux ergots de guidage 38. A cette partie fait suite une partie en forme de rampe 39 qui assurent la transition entre la face supérieure de support du ruban d'accès au niveau de la face inférieure de la semelle du boítier.Figures 8 to 10 show another mode of realization of the holding member. In this mode, the annular part designated by the reference 35, as previously of rectangular cross section, is arranged inside the case, at the bottom of it and comprises, associated with each housing opening 13, a outer protruding tab 36 for guiding the ribbon corresponding connection 3. Part 37 of the ramp rests on the upper surface of the annular part 35 and carries at its outer end two lugs of guide 38. This part is followed by a shaped part of ramp 39 which ensure the transition between the face access ribbon support upper at the underside of the sole of the case.

Pour assurer le verrouillage du dispositif gyromagnétique à l'intérieur du boítier, par l'intermédiaire du couvercle, sans risque de rotation de l'empilage des pièces de l'intérieur, l'agencement selon l'invention comporte en outre un élément anti-rotation 41 pour les pièces au-dessus de l'âme centrale 15. Cet élément peut être de nature quelconque magnétique ou non et présente, dans l'exemple représenté, la forme d'un disque portant à sa périphérie une patte anti-rotation 42 s'engageant dans une ouverture d'accès 13 du boítier. Ce disque est posé sur l'aimant supérieur 19. On constate en outre qu'un disque magnétique 44 est interposé entre le disque anti-rotation 41 et le couvercle.To lock the device gyromagnetic inside the case, by through the cover, without risk of rotation of stacking of interior parts, arrangement according to the invention further comprises an anti-rotation element 41 for parts above the central core 15. This element can be of any magnetic nature or not and presents, in the example shown, the form of a disc carrying at its periphery an anti-rotation tab 42 engaging in an access opening 13 of the housing. This disc is placed on the upper magnet 19. We see in besides that a magnetic disc 44 is interposed between the anti-rotation disc 41 and the cover.

Dans l'exemple de l'invention qui vient d'être décrit, le corps de boítier est intégré à une semelle. La figure 4 montre que le boítier pourrait bien entendu être réalisé sous forme d'un boítier indépendant.In the example of the invention which has just been described, the housing body is integrated with a sole. The Figure 4 shows that the housing could of course be made in the form of an independent box.

La figure 15 illustre un mode de fixation avantageux d'un corps de boítier 5 dans une semelle 6 en tôle métallique, habituellement en acier. Ce corps est intégré par emmanchement mécanique dans cette semelle. Dans le cas d'une tôle de faible épaisseur, afin d'éviter une désolidarisation des deux éléments, on repousse la matière de la semelle au niveau des trois ouvertures vers le corps. Comme le montre la figure, à cette fin le fond horizontal de chaque ouverture est incliné en 46 de l'intérieur vers l'extérieur de façon que le bord extérieur supérieur 47 de la semelle se trouve à la périphérie du corps de boítier au-dessus du bord inférieur de l'ouverture. Puis on repousse la matière de la semelle de son bord supérieur 47 en 48 sur le fond incliné 46 de l'ouverture. Ce repoussement garantit le maintien du boítier selon une force définie, d'une part, et d'autre part, empêche toute rotation du boítier par rapport à la semelle au moment du vissage et serrage du couvercle sur le corps de boítier.Figure 15 illustrates a method of attachment advantageous of a housing body 5 in a sole 6 in sheet metal, usually steel. This body is integrated by mechanical fitting into this sole. In the case of a thin sheet, in order to avoid a separation of the two elements, we push back the sole material at the three openings towards the body. As the figure shows, for this purpose the background horizontal of each opening is inclined at 46 by inside to outside so that the edge upper exterior 47 of the sole is at the periphery of the housing body above the edge opening. Then we push the material away the sole of its upper edge 47 to 48 on the bottom inclined 46 of the opening. This pushing back guarantees the maintenance of the housing according to a defined force, on the one hand, and on the other hand, prevents any rotation of the case by relation to the sole when tightening and tightening the cover on the housing body.

Il ressort de la description de l'invention qui précède, que l'utilisation d'un couvercle se vissant sur des filetages prévus sur la face extérieure du corps de boítier permet de réduire l'épaisseur des parois de ce dernier dans la mesure où le couvercle évite à ces parois de s'évaser. Par conséquent, il est devenu possible de réaliser le boítier par des techniques d'emboutissage ce qui assure une fabrication plus rapide et d'un coût beaucoup moins élevé que jusqu'à présent dans l'état de la technique. Lors de l'assemblage et de l'empilage des différents composants dans le corps cylindrique, ceux-ci sont efficacement maintenus centrés avec précision et sont immobilisés au moment du vissage du couvercle, grâce au corps de centrage, des plans de masse pourvus de leurs pattes, le disque anti-rotation et le blocage sur la semelle par repoussage de métal. Ainsi, le couvercle assure un verrouillage efficace.It appears from the description of the invention which precedes, that the use of a cover screwing on threads provided on the outside of the body housing reduces the thickness of the walls of this last as far as the cover avoids these walls to flare. Therefore, it became possible to make the case by stamping techniques this which ensures faster and more cost-effective manufacturing much lower than so far in the state of the technique. When assembling and stacking different components in the cylindrical body, these are effectively maintained precisely centered and are immobilized when the cover is screwed on, thanks to to the centering body, ground plans provided with their legs, anti-rotation disc and blocking on the metal embossing sole. So the cover provides effective locking.
