Patent number: 9118130Abstract: A low insertion force female terminal that is configured to make electrical contact with a male pin. The terminal includes a spring portion configured to be deflected by the pin as the pin is inserted into the terminal. The spring portion is also configured to urge a contact feature formed into the spring portion toward the pin to make electrical contact with the pin. The contact feature is characterized by an asymmetrical shape configured so a leading-edge ramp angle of the contact feature is less than a trailing-edge ramp angle of the contact feature. The asymmetrical shape reduces the peak insertion force for the terminal when compared to terminal designs that have symmetrically shaped contact features with similar dimensions.Type: GrantFiled: February 6, 2014Date of Patent: August 25, 2015Assignee: Delphi Technologies, Inc.Inventors: Thomas Andrew Volpone, Mark D.
