Patent number: 11923112Abstract: A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is ?1, the center-to-center spacing of the insulated conductors of the second conductor set is ?2, and ?1/?2 is greater than 0.7.Type: GrantFiled: April 7, 2022Date of Patent: March 5, 2024Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Douglas B. Gundel, Rocky D. Edwards, Mark M. Lettang, Charles F. Staley
