Abstract:
(EN) A waveguide comprising first and second waveguide sections, each waveguide section comprising a main body portion (12) and a connecting portion (14) at its distal end, said first and second waveguide sections being longitudinally aligned to define a conduit therethrough with a butted interface (28) therebetween, the connecting portion of each waveguide section having: (i) a first circumferential ridge (16) on its outer surface located adjacent its distal end, (ii) a second circumferential ridge (18) on its outer surface spaced apart from the first circumferential ridge, and (iii) a third circumferential ridge (20) on its outer surface located between said first and second circumferential ridges, such that a first respective recess (19) is defined between said second and third circumferential ridges and a second respective recess (17) is defined between said first and third circumferential ridges; the waveguide further comprising a sleeve member (22) over said butted interface (28), such that a respective first cavity (19a) is defined between an inner surface of said sleeve member (22) and each said first recess (19) and a respective second cavity is defined between the inner surface of said sleeve member (22) and each said second recess (17), each said first cavity (19a) having a chemical adhesive therein operative to join said first and second waveguide sections together by means of said sleeve member (22).
(FR) L'invention concerne un guide d'ondes comprenant des première et seconde sections de guide d'ondes, chaque section de guide d'ondes comprenant une partie corps principal (12) et une partie de connexion (14) au niveau de son extrémité distale, lesdites première et seconde sections de guide d'ondes étant alignées longitudinalement de sorte à délimiter un conduit en leur sein, une interface aboutée (28) les séparant, la partie de connexion de chaque section de guide d'ondes comportant : (i) une première nervure circonférentielle (16) sur sa surface extérieure située adjacente à son extrémité distale, (ii) une deuxième nervure circonférentielle (18) sur sa surface extérieure espacée de la première nervure circonférentielle, et (iii) une troisième nervure circonférentielle (20) sur sa surface extérieure située entre lesdites première et deuxième nervures circonférentielles, de façon à définir un premier évidement respectif (19) entre lesdites deuxième et troisième nervures circonférentielles et un second évidement respectif (17) entre lesdites première et troisième nervures circonférentielles ; le guide d'ondes comprenant en outre un élément manchon (22) sur ladite interface aboutée (28), de façon à délimiter une première cavité (19a) respective entre une surface intérieure dudit élément manchon (22) et chaque premier évidement (19) et à délimiter une seconde cavité respective entre la surface interne dudit élément manchon (22) et chaque second évidement (17), chaque première cavité (19a) comportant un adhésif chimique en son sein servant à solidariser lesdites première et seconde sections de guide d'ondes entre elles au moyen dudit élément manchon (22).
