Abstract

L'invention porte sur un mécanisme de connexion de guides d'onde se faisant face qui comprend : un siège de fiche de connexion placé à l'extrémité d'un guide d'onde, l'extrémité étant formée pour avoir une forme extérieure tubulaire, des filets étant sculptés dans la circonférence extérieure tubulaire, un renfoncement présentant la forme extérieure de l'extrémité du guide d'onde étant formé à l'intérieur de la forme tubulaire, et un guide d'onde débouchant dans le centre du renfoncement ; une fiche de connexion qui est placée à l'extrémité de l'autre guide d'onde faisant face au siège de fiche de connexion et est formée de façon à s'ajuster dans le renfoncement du siège de fiche de connexion, une bride faisant saillie de l'extrémité inférieure de la fiche de connexion dans la direction radiale étant formée d'un seul tenant, et l'autre guide d'onde interconnecté au premier guide d'onde débouchant dans la fiche de connexion ; et un corps de raccordement entourant la bride et la fiche de connexion, ayant des filets qui sont sculptés dans sa circonférence intérieure et dans lesquels les filets sculptés dans le siège de fiche de connexion peuvent être vissés, verrouillé rotatif à la bride, ajusté librement autour de la fiche de connexion, et fixant et libérant le siège de fiche de connexion et la fiche de connexion de façon amovible. Les guides d'onde se faisant face sont connectés par raccordement du siège de fiche de connexion et de la fiche de connexion et fixation du siège de fiche de connexion et de la fiche de connexion au moyen du corps de raccordement.
