Connector Shielding Elastic Arms Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transmission wafers in connectors lack effective noise reduction and crosstalk improvement due to incomplete common ground effect, as the shielding member is not in contact with all grounding terminals.
Innovation Solution
The transmission wafer design includes an insulating frame with grounding and signal terminals, and a shielding member with elastic arms that protrude to abut against the front grounding segments, establishing a stable electrical connection and guiding noise effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the shielding member is not in contact with all grounding terminals, then the device complexity is reduced, but the noise reduction effectiveness deteriorates
Solution Approach 1:
The shielding member incorporates elastic arms that can dynamically adjust their position and contact pressure against the grounding terminals. This dynamic structure allows the shielding member to maintain reliable electrical contact with all grounding terminals through elastic deformation, ensuring effective noise shielding without requiring overly complex rigid contact mechanisms
Solution Approach 2:
The shielding member uses flexible elastic arms instead of rigid structures to achieve contact with grounding terminals. These elastic arms can bend and conform to the positioning requirements, maintaining stable electrical connection while simplifying the overall structure compared to rigid multi-point contact systems
2Ease of manufacture
If the shielding member only contacts a portion of the grounding terminal, then the ease of manufacture is improved, but the common ground effect deteriorates
Solution Approach 1:
The elastic arms of the shielding member automatically self-adjust to contact the grounding terminals through their elastic deformation. When the shielding member is installed, the elastic arms naturally bend and make contact with the grounding terminals without requiring precise manual positioning or complex assembly procedures, achieving both ease of manufacture and reliable common ground effect
Solution Approach 2:
The elastic arms utilize elastic deformation as a key parameter to achieve contact with grounding terminals. By controlling the elastic properties and dimensions of the arms, the design ensures reliable electrical contact while maintaining simple assembly processes
3Object-affected harmful factors
If the shielding member structure is simplified, then the device complexity is reduced, but the noise guidance capability deteriorates
Solution Approach 1:
The elastic arms provide dynamic noise guidance by maintaining continuous electrical contact with the grounding terminals through elastic deformation. This simple yet effective dynamic structure guides noise signals to the grounding terminals without requiring complex rigid guidance mechanisms
