Sheet-like Buffer Member Stabilizes Contact Pin Posture

The patent applies asymmetry by using a sheet-like buffer member with a specific asymmetric configuration where the first surface faces the contact pins and the second surface faces away. This asymmetric design with a flat support base prevents the buffer member from twisting or rotating while maintaining its buffering capability through controlled elastic deformation.

The patent employs a sheet-like buffer member that functions as a flexible thin film structure. This sheet-like configuration provides both flexibility for elastic deformation to buffer contact pin behavior and stability through its planar geometry, preventing rotation or twisting that would occur with circular or non-square cross-sections.

The asymmetric sheet-like configuration with a defined first surface and second surface creates a stable, non-rotating structure. This asymmetry ensures that when the buffer member deforms to buffer contact pin behavior, it maintains a consistent orientation, thereby uniformizing the connection state between all contact pins and their corresponding terminals.

The sheet-like flexible structure allows controlled elastic deformation for buffering while the planar geometry ensures uniform deformation across the surface. This prevents differential twisting or rotation that would cause non-uniform connection states, enabling consistent electrical connections across all contact points.
