Snap Button Protrusions for Conductive Fiber Contact

The snap button is divided into multiple functional components: a male member with protrusions that pierce the conductive fiber, a female member with a recessed cavity, and a separate fastening mechanism. This segmentation allows each component to serve its specific function - the protrusions create electrical contact while the cavity provides mechanical retention, resolving the contradiction between simple structure and reliable electrical contact.

The conductive fiber is nested within the cavity of the female snap button member, while the male member's protrusions pierce through the fiber to establish electrical contact. This nested arrangement ensures both mechanical fastening and reliable electrical connectivity without requiring complex external connections, thereby improving reliability while maintaining structural simplicity.

The conductive fiber itself serves as an intermediary protective layer between the exposed metal contact surfaces and the oxidizing environment (sweat). The male protrusions pierce through this fiber layer to make contact, while the fiber and fabric layers provide a barrier that prevents direct exposure of the metal surfaces to moisture, thereby preventing oxidation and maintaining signal accuracy.

The conductive fiber and fabric layers act as flexible protective shells that envelop the metal contact surfaces. These thin, flexible layers provide corrosion protection while allowing electrical contact to pass through them, resolving the contradiction between protecting against oxidation and maintaining simple structure.

The snap button design merges mechanical fastening function with electrical contact function into a single integrated component. The male member's protrusions simultaneously pierce the conductive fiber for electrical contact and apply pressure to secure the fabric, while the female member's cavity provides mechanical retention. This combination improves fabric retention and signal accuracy without requiring separate fastening and contact mechanisms.

The snap button is designed as a multi-functional component that performs both mechanical fastening and electrical contact functions. The protrusions serve dual purposes: establishing electrical connectivity and applying clamping force to secure the fabric and conductive fiber, thereby improving retention while maintaining structural simplicity.
