RF Connector Shielding Ring for Grounding and Anti-Rocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors, particularly push-on or snap-in styles like SMP, face RF shielding performance issues due to axial misalignment and inadequate grounding, leading to degraded signal quality and susceptibility to electromagnetic interference (EMI) across various detent configurations.
Innovation Solution
A conductive EMI shielding ring with a tapered body and radial lip design is introduced, optimized to surround flexible tines and engage the male shroud, providing a consistent grounding path and high impedance cavity to enhance RF shielding performance and prevent rocking of the female connector relative to the male, regardless of detent type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conductive EMI shielding ring with tapered body and radial lip is introduced to provide consistent grounding path and RF shielding, then RF shielding performance is improved, but device complexity increases
Solution Approach 1:
A conductive EMI shielding ring is introduced as an intermediary component between the male and female connector portions. The ring includes a tapered body portion that engages the male shroud and a radial lip that engages the female connector body, creating a grounding path that shields against RF interference without requiring changes to the basic connector architecture
Solution Approach 2:
The EMI shielding ring is segmented into distinct functional portions: a tapered body portion for engaging the male shroud and providing axial alignment, and a radial lip extending from the body for engaging the female connector body. This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity
2Stability of the object's composition
If existing EMI ring designs with no gap between tines and ring are used to provide mechanical support and anti-rocking, then axial alignment is improved, but RF shielding performance degrades due to loss of grounding path
Solution Approach 1:
The EMI shielding ring incorporates a radial lip that dynamically engages with the female connector body during the mating process. This dynamic engagement ensures that the ring maintains contact with both the male shroud and female connector, preserving the grounding path while providing mechanical support and anti-rocking functionality
Solution Approach 2:
The radial lip extends in a direction perpendicular to the main body of the ring, creating a new dimensional engagement point with the female connector body. This dimensional change allows the ring to provide both mechanical stability and electrical grounding without requiring the tines to be in direct contact with the ring
3Productivity
If push-on or snap-in style connectors are used for high density applications, then productivity is improved, but axial misalignment occurs causing damage and degraded signal performance
Solution Approach 1:
The tapered body portion of the EMI shielding ring performs preliminary alignment action during the insertion process. The taper geometry guides the ring into proper axial alignment with the male shroud before final mating occurs, preventing misalignment damage while maintaining the quick-connect advantages of push-on connectors

AI summary
A connector and shielding ring for use with the connector includes a male portion with a shroud and a center conductor and a female portion with a jack and a socket positioned to receive the center conductor. A conductive shielding ring is positioned between the mated connector portions. The shielding ring has a body configured for surrounding flexible tines of the female portion jack and is configured to be captured between the tines and the shroud for providing a grounding path between the male and female portions of the connector. The shielding ring body has an inner surface with a diameter and an outer surface with a diameter and has a taper portion formed on a distal end of the shielding ring body for engaging a surface of the shroud. The shielding ring body has a lip extending radially inwardly at the proximal end for engaging the tines of the female portion when the male and female portions of the connector are mated.
