Description

TECHNICAL FIELD

[0001] The utility model relates to coaxial waveguide converter insertion technical field, especially in coaxial waveguide converter insertion device. BACKGROUND

[0002] The coaxial waveguide converter usually used is fixed by screwing the coaxial connector and waveguide tube, since the flatness and planeness of the waveguide tube and the coaxial connector shell are inevitably deviated during processing, or the connector flange is relatively thin and is prone to deformation, or the waveguide port size is relatively large, but the user has relatively strict size requirements, and the connection cannot be made more closely by increasing the number of screws, so that a gap is prone to occurring on the connection bonding surface, signal leakage is generated, the insertion loss is increased, and the user requirements cannot be met.

[0003] A coaxial waveguide converter insertion device is disclosed in the patent with the publication number CN205050972U, which includes a waveguide tube, a coaxial connector, a screw, a flexible conductive material, and a connector flange.

The connector flange 5 has a through hole for the coaxial connector 2 to pass through and be inserted into the waveguide tube 1. The diameter of the through hole of the connector flange 5 is the same as the diameter of the coaxial connector 2. The waveguide tube 1 and the connector flange 5 are fixed by the screw 3.
