WAVEGUIDE COUPLING

摘要

The present invention is aimed at providing a waveguide coupling that enables two waveguides to be easily connected together while aligning cross sections of the two waveguides to hold central axes ofthe two waveguides concentrically with high accuracy. A coupling (1) is for use in connecting two waveguides (2, 3) in an axial direction. The coupling (1) includes a continuous body (10) and a ring member (20). The continuous body (10) is used to surround in a circumferential direction a connecting portion connecting the two waveguides (2, 3). The continuous body (10) includes seven partitioning bodies (10a to 10e, 11a, 11b) hinged at six portions by gudgeons (12) to become continuous, and the partitioning bodies (11a, 11b) of end portions are connected together with screws (30), whereby the continuous body (10) is formed annularly. The ring member (20) has an annular shape, is disposed along a circumference of the waveguide (2), and is connected to the continuous body (10) by screws (40).
