Grounding Collar Notch Design for USB-C Connector Mating

The grounding collar is segmented by introducing notches that divide the grounding region into multiple sections. These notches create gaps that allow spring fingers to pass through or align with during the sliding process, preventing collisions while maintaining grounding functionality through the remaining grounding regions.

The notches act as intermediary spaces that mediate between the spring fingers and the grounding collar. By providing these intermediate gaps, the design allows the spring fingers to navigate the mating process without direct contact with the grounding collar surface, eliminating the collision risk while still achieving proper grounding contact at the intended locations.

The continuous grounding region is segmented into multiple discrete grounding sections separated by notches. This segmentation provides tolerance compensation - the spring fingers can align with any of the grounding sections, and manufacturing variations in one section do not affect the overall grounding effectiveness since other sections remain available for contact.

The design changes the geometric parameters of the grounding collar by introducing notches at specific positions and with specific dimensions. These parameter changes create a more robust design that accommodates manufacturing tolerance variations while maintaining the essential grounding and shielding functions.
