Connector arrangements for shielded electrical cables

摘要

A shielded electrical ribbon cable is disclosed. The cable includes a plurality of conductor sets including a first conductor set adjacent a second conductor set. Each conductor set includes one or more insulated conductors. The cable further includes first and second shielding films disposed on opposite sides of the cable forming cover portions and pinched portions, where the cover portions substantially surround each conductor set, and the pinched portions form pinched portions of the cable on each side of each conductor set. The insulated conductors in a conductor set are not in a same geometrical plane. A first insulated conductor of the first conductor set is nearest the second conductor set. A second insulated conductor of the second conductor set is nearest the first conductor set. The first and second insulated conductors have a center-to-center spacing S. The first insulated conductor has an outer dimension D1 and the second insulated conductor has an outer dimension D2. S/Dmin is in a range from 1.7 to 2, where Dmin is the lesser of D1 and D2.

1. A shielded electrical ribbon cable, comprising:
a plurality of conductor sets extending lengthwise along the cable and being spaced apart from each other along a width of the cable, and each conductor set including one or more insulated conductors, the conductor sets including a first conductor set adjacent a second conductor set; and a first and second shielding film disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor set; wherein, when the cable is laid flat, the insulated conductors in a conductor set having two or more insulated conductors are not in a same geometrical plane, a first insulated conductor of the first conductor set is nearest the second conductor set, and a second insulated conductor of the second conductor set is nearest the first conductor set, and the first and second insulated conductors have a center-to-center spacing S; and wherein the first insulated conductor has an outer dimension D1 and the second insulated conductor has an outer dimension D2; and wherein S/Dmin is in a range from 1.7 to 2, where Dmin is the lesser of D1 and D2.
