A ring member is disposed on a ring member mounting position. The ring member mounting position is a region between a pair of locking walls and is formed in a straight pipe shape. The ring member is in a substantially C shape with an opening at a part of its circumferential direction. The ring member may also be formed in a ring shape being connected at ring member joint parts. The ring member includes a reduced diameter part and first click parts protruding from the reduced diameter part substantially parallel in the pipe axial direction to form a slide guide. The ring member also includes second click parts of which outer diameters expand gradually from the reduced diameter part toward their tip ends. A male fitting part and a female fitting part are fitted with each other using the above ring member to obtain an electrical conduit. A connection structure for the electrical conduits, a bell block, a method for connecting electrical conduits, a method for connecting an electrical conduit and a bell block, a pipe coupling, and a ring member can be obtained thereby. The present invention can also provide a double-wall conduit of which an outer conduit is the electrical conduit having the same structures as the male fitting part and the female fitting part, a connection structure for the double-wall electrical conduits, and a conduit line using the connection structure.

An electric wire protection member to be provided at an end in a longitudinal direction of a tube that covers an outer circumference of an electric wire, the electric wire protection member including: a case; and a magnetic core provided to surround the outer circumference of the electric wire, wherein: the case includes: a core housing that houses the magnetic core; and a cover that covers an inner circumferential edge at the end of the tube, the core housing and the cover are formed in one piece with the case.

A wire harness includes an electric wire bundle and an exterior member for electric wire. The exterior member for electric wire includes a tubular exterior body for protecting the electric wire bundle, a slit formed in the exterior body along an exterior axis of the exterior body, and an inner portion continuous with a circumferential end portion of the exterior body. The inner portion is disposed on an outer side of the exterior body before the electric wire bundle is accommodated. Further, the inner portion is formed with an electric wire pressed portion against which the electric wire bundle is pressed. Further, the inner portion is pushed into the exterior body through the slit while being deformed so as to be inverted when the electric wire bundle is pressed against the electric wire pressed portion, and is accommodated in the exterior body together with the electric wire bundle.

A duct-bank stub-up assembly includes a first pre-formed stub-up module that comprises a first plurality of conduits and a first encasing body. For each of the first conduits, a first end of the conduit provides a mating end on a mating side of the first encasing body and a second end of the conduit provides a mating end on a top surface of the first encasing body. The assembly further includes a second pre-formed stub-up module that comprises a second plurality of conduits and a second encasing body formed to have a stub-up section and a footer section. For each of the second conduits, a first conduit end provides a mating end on a mating side of the footer section and a second conduit end provides a mating end on a top surface of the stub-up section. The first module is positioned on the footer of the second module.

A cable line includes a conduit having a tubular body, the wall of which is made of polymeric material, and an electrical cable provided with an outer sheath made of polymeric material and laid inside the conduit's body along its entire length. Herewith, the body wall is made with the provision of its electrically conductive properties, causing the possibility of current flow through the wall in the direction from its inner surface to the outer surface, furthermore the ratio of the diameter of the inner surface of the body wall to the diameter of the outer sheath of the cable is not less than 1.5.

The application relates to the technical field of wiring accessories, in particular to a protective tube. The protective tube includes a tube wall and fluffy warp yarns, wherein the tube wall forms a pipeline for a cable to be threaded therein and includes cross-woven first warp yarns and first weft yarns; the fluffy warp yarns are on an inner surface of the tube wall and are fluffier than the first warp yarns, the fluffy warp yarns are cross-woven with the first weft yarns and form a plurality of intersections with the first weft yarns, and each of the fluffy warp yarns spans a plurality of the first weft yarns between two adjacent intersections. When the protective tube is subjected to external impact, the tube wall with stronger hardness can protect the cable; moreover, the fluffy warp yarn reduce the friction between the protective tube and the cable.

A wire harness pipe includes an aluminum pipe, a heat shrink tube that coats the outer surface side of the aluminum pipe, and an adhesive layer that is disposed between the aluminum pipe and the heat shrink tube.

A wire harness includes electrical wires and an outer covering member. The outer covering member includes tube portions different in cross-sectional shape and size and a guiding shape portion between adjacent tube portions. The guiding shape portion guides the electrical wires when inserted. A cap is provided to each one end of the electrical wires, and the electrical wires are passed through the guiding shape portion with the caps facing frontward. A wire harness and a method for inserting electric conductive paths through the wire harness can enhance workability related to the electrical conductive paths and an outer covering member while suiting the wire harness to the shapes and the usage environments.

A wrappable, corrugated woven sleeve and method of construction thereof is provided. The sleeve includes a wall having opposite edges wrapped about a central axis into overlapping relation with one another. The wall has a plurality of layers overlying one another. Each layer includes warp yarns extending generally parallel to the central axis woven with fill yarns extending generally transversely to the warp yarns. Each layer includes a plurality of annular first bands and a plurality of annular second bands alternating with one another along the length of the wall. The first bands of each layer include monofilament weft yarn and multifilament weft yarn and the second bands of each layer include only one of monofilament weft yarn or multifilament weft yarn. The first bands overlie one another to form peaks and the second bands B overlie one another to form valleys, such that the wall has a corrugated contour.

A multilayer containment and protection tube for conduits, cables and the like, includes an inner layer made of polymeric material, which is electrically at least antistatic, with a smooth internal surface, which forms a duct for supporting conduits or cables. The tube further includes one or more intermediate layers of electrically at least antistatic reinforcement, an outer layer made of electrically at least antistatic polymeric material, and a covering and finishing layer, which is electrically at least antistatic.
