US Patent 10027037 Terminal with reduced normal force

An embodiment is directed to a receptacle terminal for receipt of a mating terminal therein. The receptacle terminal includes a contact portion which has a bottom wall and resilient contact arms. The resilient contact arms extend from opposed sides of the bottom wall. Each of the resilient contact arms has an opening extending therethrough with a first resilient contact section and a second resilient contact section extending on either side of the opening. The first resilient contact sections and the second resilient contact sections have arcuate portions which extend from the bottom wall to mating terminal engaging members. The first resilient contact sections and the second resilient contact sections generate a contact force when a mating terminal is inserted into the terminal.
