Abstract
The invention relates to a millimeter wave waveguide connecting device and a connecting method of the millimeter wave waveguide connecting device. A round flange plate with external threads is welded at one end of one waveguide. Two pin holes are designed in the round flange plate and used for allowing locating pins to be installed. A T-shaped flange plate is welded to the other waveguide which is connected with the waveguide. Two pin holes which are matched with the locating pins are designed in the T-shaped flange plate which is sleeved with a round nut. When the two waveguides are connected, the pins are matched with the pin holes in the T-shaped flange plate for locating, and the round nut is rotated to be fixedly connected with the external threads of the round flange plate, so that the outer end face of the T-shaped flange plate tightly makes contact with the outer end face of the round flange plate, and reliable connection of the two waveguides and electromagnetic wave signal transmission are achieved. When a receiver, an emitter and other electronic assemblies which are connected with the waveguides are replaced and maintained, only the round nut needs to be screwed off, and operation is conveniently and rapidly conducted.
