A wiring harness comprises a first covered electric wire, and a second covered electric wire. The first covered electric wire comprises a first electric wire conductor made of aluminum or an aluminum alloy and an insulator covering the first electric wire conductor. The first electric wire conductor comprises a wire strand of a plurality of elemental wires twisted together, and has a flat portion where a cross-section of the wire strand intersecting an axial direction of the wire strand has a flat shape. The second covered electric wire comprises a second electric wire conductor made of copper or a copper alloy and an insulator covering the second electric wire conductor. The second electric wire conductor has a lower flatness and a smaller conductor cross-sectional area than the first electric wire conductor of the first covered electric wire.

A multi-conductor bus with radially arranged conductor wires on which addressable bead devices that may incorporate light-emitting diodes (LEDs) or other surface mount devices (SMDs) can be easily mounted. The radial bus is designed to provide an improved range of flexibility and motion while allowing for easy addition of bead devices along its length that utilize self-addressing bus protocols such as cascading device protocols. The design of the flexible, interruptible radial bus facilitates the use of pass-through and interrupted paths along the bus that simplifies the installation of addressable devices along the bus such as the bus-mounted bead devices disclosed herein.

A wire harness includes an electric wire, a braided conductor covering the electric wire, a grommet having a tubular insertion portion through which the electric wire and the braided conductor are inserted, a water stop sheet sandwiched between an inner peripheral surface of the insertion portion and the braided conductor, and a fixture attached to the insertion portion so as to reduce a diameter of the insertion portion. The water stop sheet includes a base material layer having a plurality of pores communicating with each other in a thickness direction of the water stop sheet and a sealing compound layer laminated on the base material layer. The sealing compound layer is deformed so as to enter gaps between thin conductor wires constituting the braided conductor and the pores of the base material layer.

A protective member for a wire harness, having a branching point between a trunk harness and a branch harness, includes a protective sheet portion to be wound around an outer circumference of at least the trunk harness near the branching point; a pair of band-shaped fixing strip portions extending from the protective sheet portion and to be wound around on the trunk harness at a pair of spots. The branching point is between the pair of the spots. The protective member is formed from a resin. The fixing strip portions are smaller in thickness than the protective sheet portion.

A wiring member includes: at least one wire-like transmission member; and a sheet to which the wire-like transmission member is fixed, wherein a route bending portion in which the wire-like transmission member is bended and disposed is provided on the sheet, and the route bending portion includes a bending position.

A wire harness manufacturing method includes: an insertion step of inserting a binding member into an insertion hole of a protective member including a base member forming a routing space, the insertion hole provided in the base member and into which the binding member is insertable, and a temporary holding part provided on an outer surface of the base member and capable of temporarily holding an end of the binding member in a state in which the binding member is inserted into the insertion hole; a temporary holding step of temporarily holding the end of the binding member; a routing step of routing an electric wire in the routing space; and a binding step of removing the end of the binding member from the temporary holding part, and binding the electric wire to the base member by the binding member.

A wire harness includes: an electrical wire including a core wire and an insulating covering for covering the core wire; and a sheet material in which the electrical wire is disposed on a resin main surface, and a part of the main surface having contact with the electrical wire is thermally processed with the insulating covering of the electrical wire, thereby forming an electrical wire fixing part. A part of the sheet material including the electrical wire fixing part is softer than the insulating covering.

A grommet assembly includes a wire harness and a grommet including a hollow channel configured to receive the wire harness therein. At least one rib extends inwards from and substantially annularly about the interior surface of the hollow channel. At least one port configured to fluidly couple the hollow channel with an exterior environment is defined by the grommet. Material is injected into the channel through the port to secure the grommet relative to the wire harness. The material injected into the channel flows through interstices located between adjacent wires that define the wire harness so as to encapsulate the wires. The injected material also flows into other voids and openings located within the hollow channel. Upon setting, the injected material is configured to prevent movement of the grommet relative to the wire harness and to prevent the passage of contaminants through the grommet assembly.

The present disclosure provides a wire harness in which the occurrence of abnormal sound is suppressed. This wire harness (10) comprises: a cable (11); a plurality of band clips (12) which are attached to the cable (11) and are for wiring the cable (11) with respect to an external component; and a cushion sheet (13) which is more flexible than the band clips (12) and covers the individual band clips (12). The cushion sheet (13) comprises: an insertion hole (45) provided on one longitudinal end side; and an insertion section (46) provided to the other longitudinal end side. The insertion section (46) has: a base end section (47) corresponding to the width of the insertion hole (45); and an intermediate section (49) that is positioned closer to the other longitudinal end side than the base end section (47) and has a greater width than the base end section (47).

A wire harness has less differences of the amount of deflection caused by the self weight when the wire harness is constructed by arranging the plurality of the electric wire having the different cross-sectional area of the conductor. A wire harness has first and second electric wires arranged side by side in a direction intersecting an axial direction of the electric wires. Each of the first and second electric wires includes a conductor with a plurality of elemental wires, the second electric wire has a larger conductor cross-sectional area than the first electric wire has, the second electric wire has the larger outer diameter of the elemental wires composing the conductor than the first electric wire has, and the second electric wire contains a same or smaller number of elemental wires composing the conductor in comparison with the first electric wire.
