Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no shielding structure is used in the radio frequency connector, then the device complexity is reduced and manufacturing is simpler, but signal interference from external factors increases and electrical performance deteriorates
Solution Approach 1:
The patent employs a shielding frame with a thin-walled rectangular tube structure that provides effective electromagnetic shielding while maintaining manufacturing simplicity. The thin-walled design achieves the required shielding performance without excessive complexity, resolving the contradiction between reliability improvement through shielding and device complexity reduction.
2Object-affected harmful factors
If a complete and gapless ring shielding frame is used, then 360° omnidirectional shielding is achieved and anti-interference capacity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent implements a complete ring shielding frame that extends beyond the terminal area to provide excessive shielding coverage. This ensures 360° omnidirectional shielding without dead zones, effectively blocking signal interference from all directions while maintaining reasonable manufacturing precision through the continuous ring structure design.
3Reliability
If the shielding frame contacts the external PCB, then grounding is improved and shielding effectiveness is enhanced, but the assembly complexity increases
Solution Approach 1:
The patent integrates the shielding frame with the base structure through connection walls, merging multiple components into a unified assembly. The shielding frame's end surfaces contact the external PCB to establish grounding, while the integrated design with the base simplifies the overall assembly process, resolving the contradiction between enhanced shielding effectiveness and assembly complexity.

AI summary
A radio frequency connector comprises a first base. The end face of one end of a first shielding frame contacts with a first external PCB. The end, close to the first external PCB, of the first shielding frame is in the shape of a complete and gapless ring. The first shielding frame disposed around the first base is complete and gapless and can realize 360° omnidirectional and dead zone-free shielding of a first terminal on the first base, so that the anti-interference capacity of the radio frequency connector is effectively improved, and the electrical performance of the radio frequency connector is improved, accordingly.
