Waveguide tube connection device and clamp for waveguide tube connection

Abstract

A waveguide connecting apparatus including two waveguide connecting clamps each including a pair of clamp pieces positioned to oppose each other and sandwich outer peripheral portions of flanges positioned to oppose each other. A fastener pressing the pair of clamp pieces against the outer peripheral portions of the flanges. Each clamp piece includes two abutting members having first faces abutting against faces on the opposite side of faces that oppose each other of the flanges positioned to oppose each other. Second faces abutting against side faces of the waveguides, and third faces serving as tapered faces of the flanges, on the opposite side of the faces opposing each other. A pressing member with a substantially V-shaped cross section, having two inclined faces engaging with the respective third faces of the abutting members, and holding the two abutting members such that the two abutting members are respectively movable in the directions of inclination of the inclined faces with which the two abutting members respectively engage. The two waveguide connecting clamps are positioned such that directions in which the pairs of clamp pieces oppose each other intersect each other.
