Shielded Plug-in Connector Asymmetric Contact Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connections with shielding fail to achieve high data transmission rates and stability, particularly in high-frequency ranges, due to inadequate shielding and structural instability, limiting further miniaturization and repeated plugging/unplugging capabilities.
Innovation Solution
The plug connection features adjacent contact groups offset by approximately half the distance between them, allowing for increased spacing and miniaturization, with staggered L-shaped shielding elements and reinforcing ribs to enhance stability and shielding effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If L-shaped shielding elements are arranged alternately rotated by 180° in adjacent columns, then shielding coverage is improved, but manufacturing complexity increases and signal transmission quality deteriorates in very high frequency range
Solution Approach 1:
The patent applies asymmetry by offsetting contact groups in adjacent columns by approximately half the distance between them, creating an asymmetric staggered arrangement. This asymmetric positioning maximizes spacing between contact groups in different columns while maintaining symmetric L-shaped shielding elements, thereby reducing electromagnetic interference without increasing manufacturing complexity or requiring alternating rotations.
2Object-affected harmful factors
If contact groups in adjacent columns are offset by a length corresponding to the distance between signal contacts in a contact group, then spacing between contact groups is increased, but signal transmission quality deteriorates in very high frequency range
Solution Approach 1:
The patent applies parameter changes by optimizing the offset distance between contact groups in adjacent columns to approximately half the distance between signal contacts within a contact group. This parameter optimization achieves maximum spacing to reduce interference while maintaining proper signal transmission characteristics in the very high frequency range, avoiding the excessive offset that would degrade signal quality.
3Object-affected harmful factors
If signal contacts and grounding contacts are arranged offset to one another in adjacent columns, then crosstalk is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the connector into modular contact groups, where each contact group contains signal contacts surrounded by L-shaped shielding elements. These modular contact groups are then offset in adjacent columns, creating physical separation that reduces crosstalk while maintaining manageable manufacturing precision through standardized modular units rather than individual contact positioning.
4Productivity
If contact groups are arranged with maximum spacing to enable miniaturization, then connector density increases, but structural stability for repeated plugging deteriorates
Solution Approach 1:
The patent applies the nesting principle by placing stabilizing elements within the connector housing structure, nesting them inside the existing connector assembly. This allows maximum spacing between contact groups for miniaturization and high density while the nested stabilizing elements provide the necessary structural support for repeated plugging and unplugging operations without increasing overall connector size.
