Flying rod sheet fixing seat, flying rod sheet fixing structure and cavity filter

Abstract

The invention discloses a flying rod sheet fixing seat, a flying rod sheet fixing structure and a cavity filter. The flying rod sheet fixing seat comprises a base and two side plates connected to theleft side and the right side of the base; a notch is formed in the front side of the base; a left column body and a right column body spaced from the two side plates are connected to the left side andthe right side of the notch of the base respectively; a rear column body located between the left column body and the right column body is connected to the rear side of the notch of the base; the topends of the two side plates, the left column body, the right column body and the rear column body are connected to a top plate; vertical sliding grooves which correspond to the notch and are in sliding fit with installation ribs are formed among the left column body, the right column body and the rear column body; vertical sliding faces are formed on the left column body, the right column body and the rear column body respectively; at least one set of protruding parts located at the same height are arranged on the vertical sliding faces of the left column body, the right column body and the rear column body in a protruding mode; and at least one set of protruding parts are elastically extruded outwards by the installation ribs. With the flying rod sheet fixing seat, the flying rod sheet fixing structure and the cavity filter adopted, the phenomena that a flying rod sheet fixing structure is difficult to install or even cannot be installed and shakes after being installed can be solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a flying rod sheet fixing seat, a flying rod sheet fixing structure and a cavity filter. Background technique [0002] Two vertically penetrating slide grooves are formed on the front and rear sides of the existing flying rod sheet fixing seat, and the slide grooves are interference-fitted with the mounting ribs (not shown) inside the filter. However, the above-mentioned flying rod fixing seat uses the interference fit between the chute and the installation rib. When the chute width is too small, it will cause installation difficulties or even failure. When the chute width is too large, it will cause shaking after installation. Moreover, there is no extrusion deformation in the vertical and horizontal directions of the flying rod fixing seat. When the tolerance of the flying rod fixing seat is larger than that of the installation position, it will also lead to installation...

AI Technical Summary

Problems solved by technology

However, the above-mentioned flying rod fixing seat uses the interference fit between the chute and the installation rib. When the chute width is too small, it will cause installation difficulties or even failure. When the chute width is too large, it will cause shaking after installation. Moreover, there is no extrusion deformation in the vertical and horizontal directions of the flying rod fixing seat. When the tolerance of the flying rod fixing seat is larger than that of the installation position, it will also lead to installation difficulties or even failure. Hours, shaking will also occur, resulting in poor indicators or even failure
