Small-sized reed claw fisheye crimped socket contact member

The invention designs a small-sized reed claw fisheye crimped socket contact member with a small outer diameter, high reliability and a fisheye crimped end portion. The socket contact member has an outer diameter of [phi]0.77, and solves the requirement for high density and the differential impedance mismatch of an existing large-diameter contact member. The socket contact member uses a form of reed claw, has the characteristics of a high vibration level, a long insertion service life, and high reliability, and uses fisheye crimped connection to solve the via hole impedance mismatch. In addition, a joint of a [phi]0.77 fisheye back sleeve and an insulator uses puncture and piercing double feature assembly technology, thereby realizing simple assembly and reliable fixation and avoiding vibration. 本发明设计了一种外径小、高可靠、端部鱼眼压接的一种小型簧爪鱼眼压接型插孔接触件，外径为φ0.77，解决了高密度的要求，同时也解决了现有大外径接触件差分阻抗不匹配的问题，采用簧爪的形式，具备了振动等级高、插拔寿命高的高可靠性的特点，采用鱼眼压接，解决了过孔处阻抗不匹配的问题，同时φ0.77鱼眼后套和绝缘体配合处采用刺破和刺入双特征装配技术，实现了装配简单、固定可靠、没有晃动的优点。
