Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connector assembly structure is used, then device complexity is reduced, but shielding performance deteriorates causing signal fading and distortion
Solution Approach 1:
The patent implements nesting by placing the inner insulation terminal block inside the outer insulation terminal block, with conductive terminals arranged in nested rows. The second conductive terminal row is positioned within the projection area of the first conductive terminal row, creating a nested configuration that provides shielding while maintaining structural integration.
Solution Approach 2:
The patent transitions from a conventional single-plane terminal arrangement to a multi-dimensional nested structure. Conductive terminals are arranged in multiple rows with different projection areas on the terminal set projection plane, utilizing spatial dimensionality to create shielding relationships between terminals while maintaining electrical connectivity.
2Reliability
If additional jumper conductors are added for shielding, then signal transmission quality improves, but device complexity increases
Solution Approach 1:
The patent implements self-service by designing the connector assembly where the conductive terminals themselves provide shielding functions. The nested arrangement of conductive terminals with varying projection areas enables the terminals to shield each other without requiring separate jumper conductors, making the system self-sufficient for EMI protection.
Solution Approach 2:
The conductive terminals serve dual functions: electrical connectivity and electromagnetic shielding. By designing terminals with different projection areas and nested arrangements, the same terminal structures perform both signal transmission and interference protection, eliminating the need for dedicated jumper conductors.
3Object-affected harmful factors
If conductive terminals are arranged to provide shielding, then external interference resistance improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the terminal set into multiple conductive terminal rows with distinct functions. The first row provides primary electrical connectivity while the second row, with larger projection area, provides shielding. This segmentation allows each row to be optimized for its specific function while maintaining overall assembly precision through modular positioning structures.

AI summary
A connector assembly is provided. The connector assembly allows a conductive terminal to provide shielding to reduce any effect of external interference on signal transmission of the connector assembly so as to meet signal transmission requirements for the connector assembly, and with the use of a jumper conductor, at least partial conductive terminals on the connector assembly can be electrically interconnected with no need of any additional jumper, such that an electronic device using such connector assembly can be made compact in size desirably.
