A composite cable includes a pair of first electric wires, a twisted pair wire formed by twisting a pair of second electric wires having a smaller outer diameter than the first electric wires, a tape member wound into a spiral around an assembly that is formed by twisting the pair of first electric wires and the twisted pair wire together, and a sheath covering an outer periphery of the tape member. The tape member and the sheath includes an inwardly projecting part formed in a spiral along a cable longitudinal direction and formed so as to enter inward at least one of a valley part between the two first electric wires and valley parts between the first electric wires and the twisted pair wire. The inwardly projecting part has a projecting length of not less than 3% of an outer diameter of the first electric wires.

Composite cable and composite harness

[Problem] Provided are a composite cable and a composite harness that allow the improvement of cable termination workability while maintaining the flex resistance. [Solution] A composite cableis provided with a pair of first electric wires, a twisted pair wireformed by twisting a pair of second electric wireshaving a smaller outer diameter than the first electric wiresand a tape memberspirally wound around an assembled articlethat is formed by twisting the pair of first electric wiresand the twisted pair wiretogether, wherein a twist direction of the twisted pair wireis different from a twist direction of the assembled article, and the twist direction of the assembled articleis different from a winding direction of the tape member

A cable includes an assembled article formed by twisting a plurality of electric wires, a tape member spirally wound around the assembled article, and a sheath covering around the tape member. The sheath includes an injection molded body including an urethane resin. The tape member includes a non-woven fabric tape including a polyester, a polypropylene, an aramid fiber, a nylon, an acryl fiber, or a glass fiber and an air permeability defined by the Frazier method of not less than 30 cm/cm&#xb7;sec. A twist direction of the assembled article is opposite to a winding direction of the non-woven fabric tape.

Cable and wire harness

A composite cable includes a first twisted-pair wire formed by twisting a pair of first electric wires, a second twisted-pair wire formed by twisting a pair of second electric wires, a pair of third electric wires arranged between the first and second twisted-pair wires in a circumferential direction, each third electric wire having a larger outer diameter than the first and second electric wires, and a tape member spirally wound around an assembled article that is formed by twisting the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires together. The two twisted-pair wires have the same twist direction, the twist direction of the two twisted-pair wires is different from a twist direction of the assembled article, and the twist direction of the assembled article is different from a winding direction of the tape member.

A composite cable includes a first twisted-pair wire formed by twisting a pair of first electric wires which each include a first center conductor and a first insulation, a second twisted-pair wire formed by twisting a pair of second electric wires which each include a second center conductor and a second insulation, a pair of third electric wires arranged between the first and second twisted-pair wires, the third electric wires each having a larger outer diameter than the first and second electric wires and including a third center conductor with a larger cross-sectional area than the first and second center conductors and a third insulation, and a tape member spirally wound around an assembled article formed by twisting the first and second twisted-pair wires and the pair of third electric wires together. The twisted-pair wires, the assembled article and the tape member are twisted or wound in a same direction.

A composite cable is provided that improves terminal machinability while maintaining bending resistance. The composite cable is provided with: a pair of first electric wires; a twisted-pair wire obtained by twisting together a pair of second electric wires having an outer diameter that is smaller than that of the first electric wires; and a tape member spirally wrapped around an aggregate obtained by twisting the pair of first electric wires together with the twisted-pair wire. The twisting direction of the twisted-pair wire, the twisting direction of the aggregate, and the wrapping direction of the tape member are all the same direction.

A cable includes a plurality of electric wires, a tape member wound around the plurality of electric wires, and a jacket that covers an outer periphery of the tape member and includes an urethane-based resin. The tape member includes a nonwoven fabric including one of a polyester, a polypropylene, an aramid fiber, a nylon, an acrylic fiber and a glass fiber. An air permeability of the nonwoven fabric is not less than 30 cc/cm/sec.

Cable and harness

A cable includes a plurality of electric wires, a paper tape wound around the plurality of electric wires, and an outer covering that covers a periphery of the paper tape and comprises a urethane-based resin. An air resistance of the paper tape as measured by Gurley tester method is not less than 5.0 sec/100 cc.

It is an objective of the invention to provide a high-power supply cable characterized in that even when mounted in a narrow space where the cable undergoes a repetitive bending motion, any undesirable deformation out of the bending plane is small. There is provided a power-supply cable including: an electric wire including an electrical conductor and a resin sheath covering the electrical conductor, the electric wire having a tendency to generate a curl under a no-load condition, the curl having a curling direction, the curling direction being a normal to the curl, the electric wire having one or more longitudinal ends; a connecting terminal disposed at one of the longitudinal ends of the electric wire; and a curling tendency direction indicator showing the curling direction, the indicator being disposed along a normal line to the curl of the electric wire.

Power-supply cable and apparatus for manufacturing electric wire used for said power-supply cable

An electric cable includes a wire section that includes an electric wire including a conductor and a braided shield layer covering an outer periphery of the conductor and including a plurality of metal wires braided, and a cylindrical outer layer section covering an outer periphery of the wire section and including a cylindrical sheath and a braided reinforcement layer that covers an inner surface of the sheath and includes a plurality of fibers braided. The wire section is arranged inside the cylindrical outer layer section. The outer layer section is constructed such that a permissible region is formed in the cylindrical outer layer section that allows a displacement of the wire section with respect to the outer layer section in a direction orthogonal to a length direction of the wire section.
