  • Publication number: 20140138154
    Abstract: Outer-conductor-exposed portions are positioned in respective second body portions of a cable holder, and solder is supplied into solder pools provided in the respective second body portions, whereby outer conductors and ground contacts are connected to each other. Hence, even if the solder is in a molten state, a heated soldering bit does not touch the outer conductors. Therefore, the occurrence of any deformation or melting of insulators is suppressed. Furthermore, since there is no need to caulk any shield connection terminals in such a manner as to conform to the shapes of the outer conductors as in the known art, there is no chance of the insulators undergoing elastic deformation. Hence, the insulators are protected from any factors for thermal deformation and elastic deformation, and electric characteristics of differential signal transmission cables for individual finished products are thus stabilized. Consequently, the reliability of the cable assembly is improved.

  • Publication number: 20140102756
    Abstract: A differential signal transmission cable includes first and second signal lines arranged parallel to each other, a conductive layer made of a conductor in which a current is induced when signals propagate through the first and second signal lines, and a dielectric disposed between the first and second signal lines and the conductive layer. The conductive layer has a signal attenuating structure including a non-continuous section in which the conductor is non-continuous, the non-continuous section being located such that, among differential signal components and common-mode signal components included in the signals propagating through the first and second signal lines, the common-mode signal components are attenuated by an attenuation factor greater than an attenuation factor of the differential signal components.
