SHIELDED ELECTRICAL CABLE

摘要

A shielded electrical cable (50) includes conductor sets (51a, 51b) spaced apart along a width of the cable and extending along a length of the cable. Each conductor set includes first and second insulated conductors (52a, 52b), one or two drain grounding wires (54) disposed between the first and second insulated conductors, first and second conductive shielding films (56a, 56b) disposed on opposite first and second sides of the conductor set, and an adhesive layer (59) bonding the first shielding film to the second shielding film.

1. A shielded electrical cable, comprising:
a plurality of conductor sets spaced apart along a width of the cable and extending along a length of the cable, each conductor set comprising: first and second insulated conductors, each insulated conductor comprising a central conductor surrounded by an insulative material, the central conductor having a diameter D1; a drain grounding wire disposed between the first and second insulated conductors and having a wire diameter D2; first and second conductive shielding films disposed on opposite first and second sides of the conductor set and comprising primary and secondary cover portions and primary and secondary pinched portions arranged such that, in transverse cross section: the primary cover portions of the first and second shielding films in combination substantially surround each of the first and second insulated conductors; the secondary cover portions of the first and second shielding films in combination substantially surround the drain grounding wire; the primary pinched portions of the first and second shielding films in combination form primary pinched portions of the conductor set on each side of the conductor set; and the secondary pinched portions of the first and second shielding films in combination form secondary pinched portions of the conductor set on each side of the drain grounding wire; and an adhesive layer bonding the first shielding film to the second shielding film in the primary pinched portions of the conductor set, wherein: a maximum separation between the first and second shielding films in the primary cover portions is d1,max; a maximum separation between the first and second shielding films in the secondary cover portions is d2,max; a minimum separation between the first and second shielding films in the primary pinched portions is d3,min; a minimum separation between the first and second shielding films in the secondary pinched portions is d4,min; and d3,min
