US Patent 7530860 Contact terminal for electrical connector

A contact terminal for an electrical connector includes a mating section (21) defining a receiving cavity adapted for receiving a mating component. The mating section includes opposed side walls having thereon protrusions (210) extending into the receiving cavity.
