Apparatus for connecting first and second waveguide sections comprising an adhesive disposed in cavities between circumferential ridges and a sleeve member

Abstract

A waveguide comprising first and second waveguide sections, each waveguide section comprising a main body portion () and a connecting portion () at its distal end, said first and second waveguide sections being longitudinally aligned to define a conduit therethrough with a butted interface () therebetween, the connecting portion of each waveguide section having: (i) a first circumferential ridge () on its outer surface located adjacent its distal end, (ii) a second circumferential ridge () on its outer surface spaced apart from the first circumferential ridge, and (iii) a third circumferential ridge () on its outer surface located between said first and second circumferential ridges, such that a first respective recess () is defined between said second and third circumferential ridges and a second respective recess () is defined between said first and third circumferential ridges; the waveguide further comprising a sleeve member () over said butted interface (), such that a respective first cavity () is defined between an inner surface of said sleeve member () and each said first recess () and a respective second cavity is defined between the inner surface of said sleeve member () and each said second recess (), each said first cavity () having a chemical adhesive therein operative to join said first and second waveguide sections together by means of said sleeve member ().
