KR-102961723-B1 - Contact pressure adjustment method and high-speed transmission connector

Abstract

Each contact is configured to support a single contact portion by two spring pieces that are connected at both ends and extend parallel to each other while moving away from each other in the pitch direction. While maintaining a predetermined pitch and external spring gap, the two spring pieces of each contact are extended toward each other so that they are close to each other in the pitch direction, thereby increasing the contact pressure of each contact while maintaining the predetermined pitch and the impedance of each contact.
