  • Publication number: 20130146326
    Abstract: A shielded electrical ribbon cable (2) includes conductor sets (4) each including one or more insulated conductors (6), and a first and second shielding film (8) on opposite sides of the cable. In transverse cross section, cover portions (7) of the shielding films (8) substantially surround each conductor set (4), and pinched portions (9) of the films (8) form pinched portions of the cable on each side of each conductor set (4). Dense packing is achieved while maintaining high frequency electrical isolation between conductor sets (4). When the cable (2) is laid flat, a quantity s/Dmin is in a range from 1.7 to 2, where S is a center-to-center spacing between nearest insulated conductors (6) of two adjacent conductor sets (4), and Dmin is the lesser of the outer dimensions of such nearest insulated conductors (6). Alternatively, a first and second conductor set each having only one pair of insulated conductors can satisfy a condition that ?/?1 is in a range from 2.5 to 3.

  • Publication number: 20130146327
    Abstract: Various high speed shielded cables (7001) are used in combination with a connector assembly (7000). The connector assembly (7000) includes a plurality of electrical terminations (7004a) in electrical contact with the conductor sets (7005) of the cable (7001) at a first end (7007) of the cable (7001), the electrical terminations (7004a) configured to make electrical contact with corresponding mating electrical terminations of a mating connector and at least one housing (7002) configured to retain the plurality of electrical terminations (7004a) in a planar, spaced apart configuration.
