1Area of moving object
If pins are arranged in close proximity to each other on the gold finger connector, then the connector achieves compact size and high pin density, but electrical interference between neighboring pins occurs during signal transmission
Solution Approach 1:
The patent introduces signal shielding structures as intermediary elements positioned between neighboring pins on the gold finger connector. These shielding structures act as mediators that block electromagnetic fields and prevent direct electrical interference between adjacent signal pins, while allowing the pins to maintain close proximity for compact connector design.
Solution Approach 2:
The patent segments the connector surface by introducing signal shielding structures that divide the space between neighboring pins. This segmentation creates isolated electromagnetic zones around each pin, preventing interference while maintaining high pin density. The shielding structures are disposed at specific positions to segment the electromagnetic field distribution.
2Reliability
If signal shielding structures are added to suppress electrical interference, then signal quality improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the signal shielding structures with the existing pin array structure of the gold finger connector. The shielding structures are integrated into the connector body and positioned in coordination with the pin layout, combining the shielding function with the structural design rather than adding separate, independent shielding components.
Solution Approach 2:
The patent applies signal shielding structures selectively at specific locations where electrical interference is most likely to occur between neighboring pins. Rather than providing uniform shielding across the entire connector, the shielding structures are positioned locally at critical interference zones, optimizing signal quality while minimizing added complexity.
