Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electromagnetic shielding members are equipped in conventional connectors, then electromagnetic shielding capability is provided, but the shielding members cannot be effectively connected due to assembly process limitations, causing crosstalk among signal terminals
Solution Approach 1:
The housing electromagnetic shielding member is pre-integrated into the insulating housing during housing manufacturing, with connecting bumps and shield accommodating grooves prepared in advance. This preliminary integration ensures that when terminal modules are assembled, the electromagnetic shielding members can be accurately connected without assembly process limitations, effectively preventing crosstalk among signal terminals
Solution Approach 2:
Connecting bumps and shield accommodating grooves are introduced as intermediary structures to bridge the housing electromagnetic shielding member and terminal electromagnetic shielding members. These intermediaries enable effective connection between shielding members that would otherwise be difficult to connect due to assembly process constraints, thereby improving shielding reliability and reducing crosstalk
2Object-affected harmful factors
If electromagnetic shielding members are integrated into the connector housing, then electromagnetic shielding performance is improved, but the assembly complexity and manufacturing precision requirements increase
Solution Approach 1:
The housing electromagnetic shielding member is merged with the insulating housing as an integrated structure during housing manufacturing. This combining approach improves electromagnetic shielding performance while distributing the manufacturing precision requirements across the housing production process, rather than requiring separate high-precision assembly of discrete shielding components
Solution Approach 2:
The connecting bumps and shield accommodating grooves are pre-formed in the housing electromagnetic shielding member during housing manufacturing. This preliminary preparation of connection features enables subsequent assembly of terminal modules with standard precision, avoiding the need for high-precision alignment during final assembly while maintaining overall shielding effectiveness
