90-degree turning mechanism for microwave waveguide pipeline

Abstract

The invention relates to a 90-degree turning mechanism for a microwave waveguide pipeline, which is suitable for connection between two waveguide pipes with vertical transmission directions in the field of microwave communication. The 90-degree turning mechanism for the microwave waveguide pipeline comprises a microwave pipeline, wherein the microwave pipeline is formed by connecting two mutually vertical straight pipelines. A step is arranged on an outer corner pipeline wall at a right-angled connection place of the microwave pipeline, and the upper surface and the vertical surface of the step are vertical to the pipeline wall of the microwave pipeline, which on the step is located. The 90-degree turning mechanism for the microwave waveguide pipeline is characterized in that a boss vertical to the vertical surface of the step is arranged at the middle position of the vertical surface of the step, the height of the boss is less than that of the step, and gaps are arranged among both sides of the boss and the pipeline wall of the microwave pipeline. The 90-degree turning mechanism for the microwave waveguide pipeline is small in dimension, wide in use range, and easy for machining.

Description

technical field [0001] The invention relates to a microwave component. Specifically, it is a 90-degree turning mechanism for microwave waveguide pipes that can be used to change the microwave transmission direction by 90 degrees, and is suitable for the connection between two waveguides with vertical transmission directions in the microwave communication field. Background technique [0002] At present, in microwave communication equipment, the 90-degree turning mechanism of the waveguide used to change the microwave transmission direction by 90 degrees is a traditional product. This traditional microwave waveguide pipe 90-degree turning mechanism mostly adopts two structures: one is a structure that gradually bends at the joint of two waveguides that are perpendicular to each other, this structure cannot be formed on a metal block by a machining center, and The size of the gradual bend at the connection is large, which greatly limits the scope of use of the turning mechanis...

This traditional microwave waveguide pipe 90-degree turning mechanism mostly adopts two structures: one is a structure that gradually bends at the joint of two waveguides that are perpendicular to each other, this structure cannot be formed on a metal block by a machining center, and The size of the gradual bend at the connection is large, which greatly limits the scope of use of the turning mechanism; the other is a turning mechanism composed of multiple steps. When the number of steps is more than two in this structure, it is necessary to extend the tool into the waveguide Processing in the pipe, when the diameter of the waveguide pipe is small, it can only be processed with small-sized cutters, which greatly increases the difficulty of processing
