摘要： A connector for being arranged at an end of a cable includes a paddle card substrate for electrically connecting the cable to a connected device, plural device-side electrodes that are formed at an end portion of the paddle card substrate in plural rows in an insertion direction into the device and are to be electrically connected to the device, and a protective portion formed between the device-side electrodes adjacent in the insertion direction into the device to protect a surface of the paddle card substrate. The protective portion includes plural metal protective pads that are spaced from each other at a predetermined distance in the insertion direction.

摘要： A differential signaling cable includes a pair of signal conductors provided in parallel, longitudinally within the differential signaling cable, an insulator covering a periphery of the pair of signal conductors as a whole, wherein only the insulator is between the pair of signal conductors, and a shield conductor provided on an outer periphery of the insulator. An interval between the pair of signal conductors is set so that an even-mode impedance of the pair of signal conductors having the interval fixed by embedment within the insulator and covered by the shield conductor, is in a range from 1.5 to 1.9 times an odd-mode impedance for improved skew and differential mode insertion loss experienced during a transmission of high-speed signals of at least 10 Gbps.

摘要： A differential signal transmission cable includes two core wires arranged in parallel, each of the two core wires having an insulation layer on an outer periphery of a conductor; and an outer conductor provided so as to cover the two core wires all together. The insulation layer includes sequentially an inner skin layer of a non-foamed resin, a foam layer of a foamed resin, and an outer skin layer of a non-foamed resin on the outer periphery of the conductor. The outer skin layer has a higher relative permittivity than the inner skin layer. The multipair differential signal transmission includes a plurality of differential signal transmission cables and a protective jacket provided around the plurality of differential signal transmission cables.
