Provided is a rotating connector device with which it is possible to suppress an increase in the size of the device, and to reliably suppress a decrease in electromagnetic compatibility due to electromagnetic noise and to stabilize characteristic impedance. A rotating connector deviceis provided with a fixed-side housing, a rotating-side housingwhich is free to rotate relative to the fixed-side housing, and a plurality of flat cableswhich are formed by covering conductors with an insulating material and which are accommodated in a stacked state in an annular accommodating space S formed between the fixed-side housingand the rotating-side housing, wherein a shield filmis disposed at least between a first flat cableincluding first and second communication circuit conductorsand a second flat cableadjacent to the first flat cable, among the plurality of flat cables

Rotating connector device

A joining structure, a method of producing same and a wire exterior cover using the joining structure. The joining structure comprises a joining part formed by butt-welding a plate surface part of a first resin plate made of a first resin, and an end surface part of a second resin plate made of a second resin. In the joining structure, a foam resin is used for the first resin and a foam resin or a non-foam resin is used for the second resin. The joining part has a welding recess in a surface of the plate surface part. In an internal corner of a reverse surface, there is a padding section formed by melt-flowing and solidifying of at least the first resin out of the first resin and the second resin.

Joining structure, method of producing same, and wire exterior cover

Provided are a joining structure, a joining method, an exterior body for a wire harness, and a wire harness capable of firmly joining members having different physical properties while reducing the thickness of a joint part. The joining structurejoins a first membermade of a first resin and a second membermade of a second resin, wherein: the second resin has physical properties having a higher foaming ratio than the first resin; and a recessed joint partis provided which reaches at least the inside of the first memberfrom the outer surface side of the second member in a state in which the first memberand the second memberare superimposed. Furthermore, a method for manufacturing the joining structurecomprises the steps of: superimposing a first membermade of a first resin and a second membermade of a second resin having physical properties having a higher foaming ratio than the first resin; and joining the first memberand the second memberby forming the recessed joint partby pressing and hot-melting the second memberuntil the recessed joint partreaches at least the inside of the first memberfrom the outer surface side of the second member

Joining structure, joining method, exterior body for wire harness, and wire harness

An electric wire outer cover is provided which is to be fitted around an electric wire and which has a tubular housing portion where the electric wire is to be housed, the housing portion being formed of a sheet, the housing portion being formed in a folded state. Further, walls forming the housing portion include a first wall having a projection formed therefrom and a second wall having a hole formed therein, and the housing portion is formed by engagement between the first wall and the second wall through melting of the projection that has passed through the hole and welding of the melted projection to the second wall.

Electric wire outer cover and covered wire harness

An outer cover body for electrical wires, which is formed by bending a resin sheet and to be attached to an outer periphery of an electrical wire, includes a plurality of wall parts extending along an extending direction of the electrical wire and forming an accommodating part for accommodating the electrical wire. At least one of the plurality of wall parts includes a wall surface overlapping part having an outer side wall surface having a first notch, and an inner side wall surface overlapping the outer side wall surface and having a second notch. A branch line through-hole is formed by overlapping the first notch and the second notch.

Outer cover body for electrical wires and outer-cover-body-attached wire harness

A wire exterior body and an exterior-covered wire harness, capable of reducing vibration noise generated by vibration of the exterior body attached to a vehicle or the like and the wire harness in the exterior body, caused by vibration of the vehicle or the like, are provided. A wire exterior body to be attached to an outer periphery of a wire, formed by bending a resin sheet, includes a plurality of wall parts extending along the extending direction of the wire and forming an accommodating part for accommodating the wire. At least one of the plurality of wall parts has a protruding part protruding from the at least one wall part.

Wire exterior body and exterior-covered wire harness

A wire exterior body and an exterior-covered wire harness, capable of preventing damage to thereby suppress deterioration in the protective function for electric wires, are provided. A wire exterior body () formed of a resin sheet, to be mounted on the outer periphery of the wire harness (), includes bending portions () to () at which the resin sheet is bent, and a plurality of wall parts () formed of the resin sheet bent at the bending portions () to (). The wall parts () extend along the extending direction of the electric wires and form an accommodating part () that accommodates the electric wires. Grooves () to () are formed in the bending portions () to () at positions separated by predetermined spaces (S) and (S) from end portions () and (), in the extending direction of the electric wires, of the wall parts ().

Providing an outer cover body for electrical wires that can improve the degree of freedom of design while preventing anisotropy in mechanical properties and also make it possible to form even a compact outer cover body for electrical wires. An outer cover body for electrical wires that is to be attached to the outer periphery of an electrical wire, the outer cover body for electrical wires being formed of a bent thermoplastic resin foam sheet having a density of not less than 200 Kg/mand not more than 700 Kg/m.

A wire exterior body and an exterior-covered wire harness in which damage by an attaching member is prevented are provided. A wire exterior body () to be mounted on the outer periphery of an electric wire (wire harness) (), the wire exterior body being formed of a resin sheet that is bent, includes a plurality of wall parts () extending along an extending direction of the electric wire and forming an accommodating part () that accommodates the electric wire. Among the plurality of the wall parts (), at least one wall part (upper lid wall part ()) has a through-hole (), penetrating in a thickness direction of the resin sheet, into which an attaching member () attachable to a vehicle body is inserted, and a groove (a lower surface groove () or an upper surface groove ()) in which a thickness of the resin sheet is reduced is formed on a part around the through-hole () on at least one surface of an upper surface () and a lower surface () facing the thickness direction.
