Rotatory hinge of three channels broadband non -contact

The utility model relates to a rotatory hinge of three channels broadband non -contact, mainly used solve the outer conductor design of rotatory hinge of three channels broadband non -contact third passageway coaxial line and three channel group intersection is a problem, belong to radar antenna and microwave technology field. The utility model discloses a rotatory hinge of three channels broadband non -contact, first, two passageways pile up the coaxial line inner conductors of taking first, two passageways and link to each other with first, two passageway relative rotations part, and coaxial line inner conductors that the design has first, two passageways of three groove tooth structure are rotatory together as the relative rotation part that the rotation axis of rotatory hinge drove the third passageway, and the inner conductor is the global design structurally, and structural strength is high. Design transition piece between the elasticity cylinder pipe conduct third passageway coaxial line outer conducto
