Patent number: 9450322Abstract: The present invention relates to electrical contacts having tines with uneven edges to provide increased contact normal force and decreased peak stress. The socket electrical contact contains a socket body that includes a base defining a longitudinal axis and tines extending from the base at spaced-apart locations around the circumference of the base. The tines extend from the base in the direction of the axis to define a pin reception zone between the tines. Each tine contains two opposing edges that have different lengths and a blunt tip.Type: GrantFiled: January 16, 2015Date of Patent: September 20, 2016Assignee: AMPHENOL CORPORATIONInventor: Zlatan Ljubijankic
