Description

La présente invention concerne un boîtier contenant les composants d'un coupleur directif coaxial, notamment pour des fréquences comprises entre 30 et 18000 MHz.The present invention relates to a box containing the components of a coaxial directional coupler, in particular for frequencies between 30 and 18000 MHz.

Les boîtiers connus tels que ceux décrits dans les documents FR-A- 2 059 694 et US-A- 3237134 présentent généralement une structure compliquée, notamment de nombreuses fixations parvis, ce qui favorise les fuites des courants à haute fréquence. De plus, ils comportent des cavités dont l'usinage précis entraîne un prix de revient élevé.Known housings such as those described in documents FR-A-2 059 694 and US-A-3237134 generally have a complicated structure, in particular numerous fastenings in front, which favors the leakage of high frequency currents. In addition, they include cavities whose precise machining results in a high cost price.

La présente invention a pour but de proposer un boîtier présentant une très grande simplicité mécanique, les pertes électriques se trouvant donc réduites à une valeur minimale.The object of the present invention is to propose a housing having very great mechanical simplicity, the electrical losses therefore being reduced to a minimum value.

En outre, il réduit la durée des études nécessaires pour réaliser un couplage donné.In addition, it reduces the duration of the studies necessary to achieve a given coupling.

A titre indicatif, le prix de revient de ce boîtier est particulièrement bas, de l'ordre du sixième vis-à-vis des boîtiers conventionnels.As an indication, the cost price of this box is particularly low, of the order of a sixth vis-à-vis conventional boxes.

La présente invention a pour objet un boîtier contenant les composants d'un coupleur directif coaxial, comportant un corps de boîtier dont chacune des parois latérales comporte deux ouvertures, une ouverture d'une des parois étant disposée en vis-à-vis de l'ouverture de l'autre paroi, caractérisé en ce que le corps présente une section en forme de U et en ce que le boîtier comporte un couvercle obturant la partie supérieure dudit corps de boîtier, et deux embouts obturant les extrémités de l'ensemble corps de boîtier couvercle.The subject of the present invention is a housing containing the components of a coaxial directional coupler, comprising a housing body, each of the side walls of which has two openings, one opening of one of the walls being disposed facing the opening of the other wall, characterized in that the body has a U-shaped section and in that the housing has a cover closing the upper part of said housing body, and two end pieces closing the ends of the body assembly housing cover.

D'autres caractéristiques et avantages de l'invention ressortent de la description qui suit donnée en référence aux dessins annexés dans lesquels:Other characteristics and advantages of the invention appear from the description which follows, given with reference to the appended drawings in which:

La figure 1 représente une vue éclatée en perspective des organes constituant le boîtier selon l'invention.Figure 1 shows an exploded perspective view of the members constituting the housing according to the invention.

La figure 2 représente lesdits organes mutuellement assemblés et formant le boîtier selon l'invention.Figure 2 shows said mutually assembled members and forming the housing according to the invention.

En référence à la figure 1, le boîtier 1 comporte un corps 20 présentant une section en forme de U. Chacune des parois latérales du U comporte deux ouvertures 2, sensiblement vers l'extrémité, une ouverture de l'une des parois étant en vis-à-vis de l'ouverture de l'autre paroi. Une rainure 3 est ménagée à la partie supérieure de chaque paroi latérale au-dessus des ouvertures 2.Referring to Figure 1, the housing 1 has a body 20 having a U-shaped section. Each of the side walls of the U has two openings 2, substantially towards the end, an opening of one of the walls being screwed opposite the opening of the other wall. A groove 3 is made in the upper part of each side wall above the openings 2.

Par ailleurs deux alésages 4 sont prévus aux extrémités du fond du corps de boîtier 20.Furthermore, two bores 4 are provided at the ends of the bottom of the housing body 20.

La référence 5 désigne un couvercle présentant des rebords 6 aptes à s'engager dans les rainures 3 du corps de boîtier 20, ainsi que deux alésages 7 à ses extrémités et venant en vis-à-vis des alésages 4 du fond du corps du boîtier 20 lorsque le couvercle 5 est mis en place.The reference 5 designates a cover having flanges 6 able to engage in the grooves 3 of the housing body 20, as well as two bores 7 at its ends and coming opposite the bores 4 of the bottom of the housing body 20 when the cover 5 is put in place.

On a référencé en 8 deux embouts destinés à obturer les extrémités de l'ensemble corps de boîtier-couvercle. Chacun de ces embouts comporte un corps 9 percé d'un alésage 10 et pouvant être introduit entre le corps de boîtier 20 et le couvercle 5, et un rebord 11 venant en appui sur les extrémités de l'ensemble corps de boîtier-couvercle. Lesdits alésages 10 sont disposés en vis-à-vis des alésages 4 et 7 du corps du boîtier 20 et du couvercle 5 respectivement.There have been referenced at 8 two end pieces intended to close off the ends of the housing body-cover assembly. Each of these end pieces comprises a body 9 pierced with a bore 10 and which can be introduced between the housing body 20 and the cover 5, and a flange 11 bearing on the ends of the housing body-cover assembly. Said bores 10 are arranged opposite the bores 4 and 7 of the housing body 20 and the cover 5 respectively.

L'ensemble des organes précédemment décrit est serré au moyen de douilles 12 introduites dans les alésages 4, 7 et 10 ménagés dans les organes du boîtier.All of the above-described members are clamped by means of sockets 12 introduced into the bores 4, 7 and 10 formed in the members of the housing.

La figure 2 illustre le boîtier monté.Figure 2 illustrates the mounted housing.

A la manière connue chaque ouverture 2 est couplée à un connecteur et assujettie à ce dernier au moyen de petites ouvertures 13 disposés de part et d'autre de chaque ouverture 2 et pouvant recevoir une vis ou autre moyen de fixation.In the known manner, each opening 2 is coupled to a connector and secured to the latter by means of small openings 13 arranged on either side of each opening 2 and capable of receiving a screw or other fixing means.

Bien que le dispositif qui vient d'être décrit paraisse le plus avantageux pour la mise en oeuvre de l'invention dans une situation technique particulière on comprendra que diverses modifications peuvent lui être apportées sans sortir du cadre de l'invention, certains de ses éléments pouvant être remplacés par d'autres susceptibles d'y assurer la même fonction technique ou une fonction technique équivalente.Although the device which has just been described seems the most advantageous for the implementation of the invention in a particular technical situation, it will be understood that various modifications can be made to it without departing from the scope of the invention, some of its elements may be replaced by others capable of performing the same technical function or an equivalent technical function.
