Abstract: A differential signal cable for transmitting high-speed digital differential signals of several Gbit/s or more is provided to minimize characteristic impedance mismatch and to repress increase in the skew, or increase in disturbance due to differential-mode to common-mode conversion. A differential signal cable comprises two insulated wires arranged parallelly in a contact, each of said two insulated wires comprising a conductor and an insulator jacketing the conductor; a fusion layer provided on the surface of each of said two insulated wires; a drain wire placed longitudinally in a recess created in the interstice between said two insulated wires; and a shield tape lapping around said two insulated wires and said drain wire together, wherein a surface of said insulator of each of said two insulated wires is partially deformed so as to have a flat portion and said two insulated wires are fused each other at said flat portions.

Abstract: A differential signal transmission cable has a pair of insulated wires, a first tape and a second tape. Each of the first and second tapes is made of a base material having an electrical insulating property and an electrical conductive film formed on at least one surface of the base material. The first tape is spirally wound around the insulated wires such that the electrical conductive film is provided outside. The second tape is spirally wound around the first tape such that the electrical conductive film of the second tape contacts with the electrical conductive film of the first tape. Among angles made by an upper edge of the insulated wires and an edge of the first tape in a side view in which a longitudinal direction of the pair of insulated wires is a horizontal direction, a first angle made on one end side of the insulated wires is an acute angle in the first tape.

Abstract: A differential signal transmission cable has a pair of conductors arranged to be distant from each other and parallel to each other, an insulator covering the pair of conductors, and a shield conductor wound around the insulator. The insulator has an outer periphery shape of a transversal cross section in that a plurality of curved lines with different curvature radiuses are combined. The shield conductor has an inner periphery shape of a transversal cross section in that the plurality of curved lines are combined in accordance with the outer periphery shape of the insulator.

Abstract: A connection structure for connecting a differential signal transmission cable to a circuit board. A differential signal transmission cable includes an outer conductor provided around a pair of signal line conductors via an insulator. Parts of the signal line conductors are exposed from a tip of the differential signal transmission cable. A circuit board is provided with a pair of signal pads and a ground pad. A shield-connecting terminal includes a main body which is crimp-connected to the outer conductor and a solder-connecting pin which is solder-connected to the ground pad. The exposed parts of the signal line conductors are solder-connected to the signal pads, respectively, and the outer conductor is solder-connected to the ground pad via the solder-connecting pin of the shield-connecting terminal.

Abstract: A direct attach cable includes a cable connected to a paddle card, a housing formed to store the paddle card and the end portion of the cable, a latch engaged with an engaging portion of a plate spring provided on the cage when the housing is inserted in the cage, a de-latching lever in a lever shape for releasing the engagement between the latch and the plate spring, the de-latching lever pushing up the plate spring to disengage the engaging portion of the plate spring from the latch, a link formed in a frame shape so as to be fitted to the housing on the rear end side in the insertion direction, the link pushing up the plate spring via the de-latching lever by moving toward the rear end side, and a pull-tab for moving the link on the rear end side of the housing in the insertion direction.
