Radial frequency module, shell structure of radio frequency module and thread self-locking structure

Abstract

The invention relates to a radial frequency module, a shell structure of the radio frequency module and a thread self-locking structure. The thread self-locking structure comprises a column body. A threaded hole is formed in the column body. The end face of the column body is concave towards to the threaded hole. The outer wall of the column body is provided with multiple deformation grooves whichare distributed in the circumferential direction of the column body. Deformation portions capable of being squeezed and deformed are formed between the deformation grooves and the end face. The end face is provided with openings extending in the radial direction of the column body. The openings are located between the adjacent two deformation grooves. In the screw tightening process, the deformation portions are squeezed to generate expansion deformation, deformation of the deformation portions enable threads on the inner wall of the threaded hole to generate tidy displacement, the gap between the threads on the inner walls of the threaded hole and threads on the screw is reduced, friction force is formed, and the self-locking purpose is achieved. The thread self-locking structure can prevent threaded connection from being loose and prevent the screw from falling; and besides, since the thread self-locking structure is used for looseness prevention, the structure is simple, the reliability is high, and assembly and disassembly of the screw are convenient.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a radio frequency module, its housing structure and a threaded self-locking structure. Background technique [0002] The RF module structure is a structural form often used in communication systems. The main function of the RF module is to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one area to another. Use RF modules to surround components, circuits, cables, and interference sources of the entire system to prevent the interference electromagnetic field from spreading outward; use RF modules to surround receiving circuits, equipment or systems to prevent them from being interfered by external electromagnetic fields. [0003] The traditional RF module structure is divided into two parts, the base plate and the cover plate. The cover plate and the base plate are locked by countersunk screws, and the cover pl...
