Multi-Part Shield Structure for Compact High-Frequency Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors lack an effective shield structure to provide sufficient noise shielding for high-frequency communication systems, which is essential for maintaining good transmission characteristics and reducing noise interference.
Innovation Solution
A connector design featuring a shield member with multiple shield portions strategically positioned around the contacting portions, including a first shield portion inside and a second shield portion outside the contact area, along with a third shield portion on the circuit board side, to effectively shield noise from entering or escaping the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shield structure is added to the connector to provide noise shielding for high-frequency communication, then the noise shielding effect is improved, but the connector size increases
Solution Approach 1:
The shield member is nested within the insulator structure, with the shield portion positioned inside the insulator housing. This allows the shield to be integrated into the existing connector geometry without adding external dimensions, achieving noise shielding while maintaining compact connector size.
Solution Approach 2:
The shield portion extends in the width direction (perpendicular to the fitting direction) rather than increasing the connector length in the fitting direction. This dimensional reorientation provides effective noise shielding coverage without proportionally increasing the overall connector volume.
2Volume of moving object
If the shield member is positioned outside the contact member to reduce connector size, then the connector width is reduced, but the noise shielding effectiveness deteriorates
Solution Approach 1:
The shield member is nested within the insulator structure, with the shield portion positioned inside the insulator housing. This allows the shield to be integrated into the existing connector geometry without adding external dimensions, achieving noise shielding while maintaining compact connector size.
Solution Approach 2:
The shield portion is strategically positioned adjacent to the contact portion where noise shielding is most critical. By concentrating shielding material in the local region near the contacts rather than providing uniform shielding throughout, the design achieves effective noise protection while minimizing overall connector dimensions.
