Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0029] It should also be noted that the orientation terms such as left, right, up and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should not be regarded as re...

Abstract

The invention is applicable to the field of cavity filter manufacture, and provides a cavity filter assembly process for assembling a cavity filter. The cavity filter assembly process includes the steps: solder coating: coating the lower end face of a resonance rod with rod end solder with hot melting characteristics, and coating the lower surface, abutted to a cavity, of a cover plate with plateend solder with hot melting characteristics; preassembly: assembling the resonance rod to the cavity, abutting the lower end face of the resonance rod to the bottom of a containing groove, and assembling the cover plate onto the cavity to close a notch of the containing groove by the cover plate; welding: heating the rod end solder and the plate end solder together and melting the rod end solder and the plate end solder together. The resonance rod and the cover plate are welded on the cavity once in a soldering mode, the number of work fixtures is decreased, operation procedures are decreased,and operation efficiency is greatly improved. Moreover, connecting closure is improved, and signal leakage is avoided.

Description

technical field [0001] The invention belongs to the field of cavity filter manufacturing, and in particular relates to a cavity filter assembly process. Background technique [0002] During the processing of the cavity filter, in the prior art, the cover plate and the cavity are screwed together for connection and fixation. Screw holes are set on the upper surface of the cavity, and through holes through which the screws can pass are set on the cover plate. into a closed electromagnetic shielding space. Since the cavity filter needs to seal the signal, a large number of screws need to be installed, resulting in very low assembly efficiency and high material and labor costs. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a cavity filter assembly process, which aims to solve the problem of poor assembly efficiency. [0004] The present invention is achieved like this: ...
