Solderless SPE Wire-to-Board Connector With Press-Fit and IDC Contacts

The patent replaces the thermal soldering process with a mechanical press-fit connection system. The connector uses a press-fit pin that mechanically engages with a receptacle on the PCB, eliminating the need for soldering while providing reliable electrical connection. This mechanical substitution resolves the contradiction by making connections easier to make and repair while maintaining reliability through precise mechanical engagement and contact pressure.

The patent divides the connection system into separable components: a connector assembly with press-fit pins and a PCB receptacle. This segmentation allows the connection to be stable during operation while enabling easy separation for repair or replacement. The mechanical interface can be disconnected and reconnected multiple times without damage, resolving the contradiction between stability and repairability.

The press-fit pins are pre-formed with the appropriate geometry and mechanical properties during manufacturing. This preliminary action eliminates the need for time-consuming soldering operations during assembly. The connector can be directly pressed into the PCB receptacle, providing strong electrical bonds instantly without thermal processing, thereby increasing productivity while maintaining connection strength.

The patent substitutes the time-intensive soldering process with a rapid mechanical press-fit operation. The press-fit pin makes immediate electrical contact upon insertion into the PCB receptacle, eliminating the heating, melting, and cooling cycles required for soldering. This mechanical approach establishes reliable electrical connectivity in seconds rather than minutes, significantly reducing time loss while maintaining connectivity reliability.
