A method of manufacturing a wire harness having an electric wire and a protection tube covering, one end side of the electric wire being provided with a large-dimension portion greater than an inner dimension of the protection tube, including shaping the electric wire protection tube made of shape-memory polymer into a tube shape; expanding the protection tube by heating to a temperature equal to or higher than a glass-transition point such that the inner dimension of the protection tube becomes larger than the large-dimension portion; cooling the protection tube to a temperature below the glass-transition point and solidifying the protection tube; passing the large-dimension portion and the electric wire inside the protection tube; and reheating the electric wire protection tube to a temperature equal to or higher than the glass-transition point such that the electric wire protection tube is restored to the inner dimension obtained after the step of shaping.

It is aimed to provide a wiring harness, in which a part where a wire conductor is exposed from an insulation coating is covered by a waterproof portion and which can maintain the adhesiveness of the waterproof portion to the insulation coating containing a plasticizer even if being placed in a high-temperature and high-humidity environment. A wiring harness is provided with a wire including a conductor, an insulation coating covering an outer periphery of the conductor and a conductor exposed portion, in which the conductor is exposed from the insulation coating, and a waterproof portion for integrally covering surfaces of the conductor exposed portion and the insulation coating. The insulation coating contains a plasticizer. The waterproof portion is constituted as a cured body of a resin composition containing a urethane (meth)acrylate oligomer and a nitrogen-containing monomer, which is a radical polymerizable monomer containing a nitrogen atom.

A cable assembly includes a cable and a cable mounting clamp. The cable mounting clamp includes a base removably connectable to a surface. The base may include a tab removably insertable into an aperture defined in the surface and a lock releasably connectable to the surface. The base further includes an outer body which defines an inner channel and a support ramp disposed within the inner channel, the inner channel extending along a longitudinal axis. The cable mounting clamp further includes a cap connectable to the base to further define the inner channel therebetween. The cable mounting clamp further includes a roller tube disposed within the inner channel and rotatably mounted on the support ramp, the roller tube rotatable about the longitudinal axis.

A conductive wire has a peripheral disposition part disposed around a center member and an extension part integrally formed with the peripheral disposition part so as to extend from the peripheral disposition part. A plurality of conductive wires are disposed. A sheath is disposed so as to cover the center member and the peripheral disposition part. A tube is disposed so as to surround an end portion of the sheath and a part of the extension part, and is thermally shrinkable. An adhesive is disposed inside the tube and is melted or softened by heat.

A wire harness that comprises a connecting portion in which a first conductor exposed at a terminal portion of the first wire by stripping an insulating coating therefrom is connected to a second conductor exposed at a terminal portion of a second wire by stripping an insulating coating therefrom, the second wire having a higher flexibility than the first wire. The wire harness also comprises two layers of shrinkable tubes fitted around the outer circumference of the connecting portion. According to this structure, even if one of the shrinkable tubes is torn, the other shrinkable tube can provide protection to the connecting portion, thus improving the durability of the connecting portion.

A textile sleeve for routing and protecting a plurality of elongate members in spaced relation from one another is provided. The sleeve includes a single piece, monolithic wall of interlaced yarn extending lengthwise between opposite ends of the sleeve. The wall includes a plurality of circumferentially continuous, tubular wall sections extending lengthwise between the opposite ends, with adjacent tubular wall sections being fixed in laterally spaced relation from another by an intervening single layer section. At least some of the yarn within each tubular wall section is provided as heat-shrinkable yarn, thereby providing each tubular wall section as being heat-shrinkable from a first, diametrically enlarged assembly state to a second, diametrically constricted state about a corresponding elongate member contained therein.

A heat shrink component includes a heat shrink layer and a heating unit in thermal contact with at least a part of the heat shrink layer and heating the heat shrink layer to a heat shrink temperature. The heating unit includes an electrically conductive lead formed of copper and/or aluminum and having an electrical conductivity of more than 3.Math.10.sup.7 S/m. The heat shrink component has a first dimension in an expanded state and a second dimension in a shrunk state after heating. The first dimension is larger than the second dimension.

A method for litz wire termination includes placing a ferrule over exposed conductors on an end of litz wire. The exposed conductors include a portion of the litz wire without an external insulation layer, and a portion at the end of the litz wire protrude past the ferrule. The method includes crimping the ferrule to the litz wire and placing the end of the litz wire with the ferrule in molten solder past the end of the ferrule. The method includes maintaining the litz wire in the molten solder until insulation on conductors of the litz wire is removed from the conductors in the molten solder and solder bonds to the conductors that are within in the molten solder. The method includes removing the litz wire from the molten solder and allowing the litz wire to cool until molten solder bonded to the conductors transitions to a solid state.

The invention relates to a method for sealing a contact point region comprising at least one contact point at an electrical line connection, wherein the line connection comprises at least one electrical line and at least one conductive element electrically connected thereto. The method starts by arranging a shrink tube on the outer circumference of the contact point region, in a first region extending over the contact point region on both sides in the longitudinal direction. This is followed by heating the shrink tube to shrinking temperature. During the heating of the shrink tube, an inductive heating of the electrical conductor is additionally performed, at least in the contact point region, and so hotmelt adhesive arranged inside the shrink tube and/or on the outer circumference of the contact point region is heated to its melting temperature. The invention also relates to a device for sealing a contact point region and to a sealing at such a region.
