An electrical connection box including a case, a relay attached to the case in a state exposed outside the case, and a wire harness that is to be connected to a sensor that measures a state of the relay, and is provided outside of the case. The wire harness includes a lead to be electrically connected to the sensor, and a guide member that is provided along the lead so as to guide the extending direction of the lead.

A tape includes a tape base material obtained by kneading, into a PVC resin added with a plasticizer, a stabilizer and a coloring agent, a filler in a particle state such as calcium for improving tearability. A color of the tape base material is set to a receding color other than black by an action of the coloring agent. The tape end portion of the PVC tape is whitened by tearing.

An apparatus to process a plurality of electrical wires as well as a method that uses the apparatus are indicated. The apparatus includes a feed device, a stationary holding device, a holding device that is non-stationary along a linear guiding direction, a non-stationary bundling device that is separate from the non-stationary holding device and a controller connected to a drive of the non-stationary bundling device. The stationary holding device and/or the non-stationary holding device are configured to twist the respectively held end of the wires; The controller controls the drive in such a way that a distance between a bundling segment of the non-stationary bundling device and the non-stationary holding device assumes a specified or a specifiable distance.

An object of the present invention is to make it easy to bind a plurality of electric wires together. An electric wire bundle includes an electric wire group and a binding portion. The electric wire group includes a bundle portion in which at least a portion of a plurality of electric wires in an extension direction is bundled together. The binding portion formed by supplying a fluid binding portion forming material to an outer circumferential portion of the bundle portion in strip-shape in a form in which the bundle portion can be maintained in a bundled state and curing the binding portion forming material. Such a bundle can be formed by discharging the fluid binding portion forming material from a nozzle to the circumference of a bundle portion of a plurality of electric wires supported by an electric wire supporting portion, and curing the fluid binding portion forming material.

A composite harness includes a composite cable that includes a plurality of first electric wires, a multicore wire formed by covering a plurality of second electric wires having a smaller diameter than the plurality of first electric wires with one urethane-based resin inner sheath to be in contact with the first electric wires, and a jacket covering an outer periphery of the plurality of first electric wires and the multicore wire, and a molded resin provided at an end portion of the composite cable so as to cover an outer surface of the inner sheath at an end portion of the multicore wire. The outer surface of the inner sheath is irregularity-formed at least at a portion in contact with the plurality of first electric wires and a portion covered with the molded resin.

A method is disclosed for additively manufacturing a composite wiring harness. The method may include directing a plurality of conductors through a print head, directing at least one reinforcement through the print head, and coating at least one of the plurality of conductors and the at least one reinforcement with a matrix material. The method may also include discharging the at least one of the plurality of conductors and the at least one reinforcement with the matrix material from the print head, and exposing the matrix material during discharging to a cure energy to cause hardening of a sheath around the plurality of conductors.

A wiring harness assembly includes a plurality of separated conductors formed of an electrically conductive material, a substrate formed of a dielectric material encasing the plurality of separated conductors, a location feature integrally formed with the substrate and an opening defined in the substrate having a predetermined size and shape. A section of the plurality of separated conductors is exposed within the opening. The opening is precisely located relative to the location feature.
