It is aimed to provide a wiring harness excellent in the deep curability of a part covered with a water blocking material. In a wiring harness in which an exposed conductor part of an insulated wire is covered with a water blocking material, the water blocking material is a cured product of a photocurable composition containing a photocurable resin and a photopolymerization initiator, and a content of the photopolymerization initiator in the photocurable composition is 0.2 parts by mass or more and 2.0 parts by mass or less based on 100 parts by mass of the photocurable resin.

An electrical cable for vertical applications includes a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers including a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also includes at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube.

A cable harness that has water-sealing properties includes a sheath that accommodates an ABS sensor cable and a parking brake cable. The ABS sensor cable and the parking brake cable branch apart at an end portion of the sheath. An integrally molded member includes, in an integrated manner, a water-sealing portion that seals the end portion of the sheath from water, and a bracket attachment portion that is attached to the bracket.

An insulated wire includes a conductor, and a flame-retardant insulation layer that includes a resin composition including a flame retardant and is arranged around the conductor, and a water-blocking layer that is arranged around the flame-retardant insulation layer and has a water absorption of not more than 0.5% at saturation. The thickness of the water-blocking layer is not less than 25 μm.

A method of sealing a wiring-harness includes the steps of: a) dispensing a length of a sealing-tape onto a platform, the sealing-tape having a first-surface and a second-surface opposite the first-surface. b) separating a plurality of wire-cables from a portion of the wiring-harness. c) applying the plurality of wire-cables to a first-half of the first-surface of the sealing-tape. d) folding a second-half of the sealing-tape over the separated plurality of wire-cables such that the second-half overlays the first-half. e) pressing the second-half of the sealing-tape such that the second-half contacts the first-half between the separated plurality of wire-cables, thereby forming a cable-band. f) coiling the cable-band into a generally cylindrical-shaped seal. g) compressing the cylindrical-shaped seal isostatically such that interstitial-voids within the cylindrical-shaped seal are reduced in size. An apparatus for sealing a wiring-harness is also provided.

A smooth torque balanced cable that includes an electrically conductive cable core for transmitting electrical power. The smooth torque balanced cable also has a first polymer surrounding said cable core. An inner layer of a plurality of first armor wires surrounds the cable core. The first armor wires being in partial contact with the first polymer and partial contact with a second polymer disposed opposite the first polymer.

A cable sealing article has first and second sections, each section having a top wall, a bottom wall, and side walls. The top wall of each section has a plurality of cut-out openings shaped to partially circumscribe one of the plurality of electrical core wire conductors of the service entrance cable. The bottom wall of each section has a single cut-out opening. Each section also has an interior cavity located between the top, bottom, and side walls. In its use position, the article is configured to encapsulate the core wire connectors of the service entrance cable at their meter panel entry location. One of the two sections has a port opening in which silicone material is injected to fill the interior cavities of the first and second sections, thereby providing a waterproof seal to the service entrance cable as it enters the meter panel.

A system and method is disclosed. The method comprises a client device receiving a verification request comprising an interaction identifier. The client device can then query a full node for a random sampling of block headers from the full node. The client device can receive the random sampling of block headers from the full node, and verify the random sampling of block headers. The client device can then determine that the blockchain maintained by the full node is valid after verifying the random sampling of block headers.

The present invention provides an earth terminal which is provided with a water sealant layer on a connecting part connected to a wire, the earth terminal being provided with a structure that can suppress the occurrence of the floating of a seating surface of the earth terminal during an earth connection, the floating of the seating surface being caused by a water sealant hanging down in the earth terminal whereby the earth terminal exhibits superior effects in terms of space-saving and cost suppression. The present invention also provides a wire harness provided with the earth terminal. This earth terminal 1 is provided with a terminal fixture 10 having a crimping part 11 for crimping and fixing a wire 40, and a fastening part 15 connected to the earth surface by a fastening member, the terminal fixture 10 being provided with a step having a height D of 2.88 mm to 7.0 mm inclusive between the crimping part 11 and the fastening part 15, wherein a water sealing layer 20 covers at least the crimping part 11 of the terminal fixture 10 and comprises a water sealant for water sealing the wire 40. This wire harness 2 has the earth terminal 1 and the wire 40, wherein an end part of the wire 40 is crimped and fastened by the crimping part 11 of the earth terminal 1 and is covered with the water sealing layer 20.

A power cable has a cable core comprising at least one conductor with an insulating system and a water barrier surrounding the cable core. The water barrier comprises a helically wound strength bearing layer interconnected by a low melting point material.
