A first sealant/adhesive is configured to cooperate with the heat shrinkable tubing. The first sealant/adhesive has a first sealant/adhesive first surface and an oppositely facing first sealant/adhesive second surface. The second surface of the first sealant/adhesive is bonded to the inner wall of the heat shrinkable tubing. A second sealant/adhesive is configured to cooperate with free ends of electrical conductors which are in electrical engagement with the electrical terminal. The second sealant/adhesive has a second sealant/adhesive first surface and an oppositely facing second sealant/adhesive second surface. The second sealant/adhesive first surface is provided in engagement with the electrical conductors. The second sealant/adhesive second surface is provided in engagement and bonded with the first sealant/adhesive first surface.

A connection structure includes: a circuit breaker connected to a power cable through which high-voltage power is supplied; a high-voltage device box accommodating the circuit breaker; a main transformer configured to transform a voltage of the high-voltage power and provided under the floor of the car; a first connector device electrically connected to the circuit breaker and provided at a dividing wall of the high-voltage device box; a second connector device electrically connected to the main transformer and provided at a dividing wall of the main transformer; and a high-voltage cable covered with an insulating coating and having both end portions to which cable connector portions are respectively attached, wherein the high-voltage cable connects the first connector device and the second connector device in such a manner that the cable connector portions respectively fit and are connected to the first connector device and the second connector device.

A terminal-equipped wire is provided with an insulated wire including a core and an insulation coating covering the periphery of the core, a terminal including a wire connecting portion connected to the insulated wire, a heat shrinkable tube configured to cover the periphery of the wire connecting portion while being shrunk by receiving heat, and a sheet-like intervening member provided between the heat shrinkable tube and the terminal.

A seal structure that includes: a multicore cable in which first to fourth electrical wires are enveloped by a sheath, the electrical wires extending out from an end portion of the sheath; a rubber plug through which the electrical wires pass, the rubber plug being fitted around the end portion of the sheath; a cap that is fitted around the rubber and presses the rubber plug inward; and a crimping member that is arranged adjacent to the rubber plug and is crimped around the sheath. The crimping member has a locking piece and a mating portion, and the cap has an extending piece and a receiving recession portion. Relative positions of the crimping member and the rubber plug are held by the mating portion of the locking piece and the receiving recession portion of the extending piece locking together.

A cable system for use downhole includes a connector assembly having a body and a bore formed therethrough; a conductor disposed through the bore of the connector assembly; and a first insulation layer disposed around the conductor. An insulator tube is disposed around the conductor and has an end attached to the first insulation layer. The insulator tube may be made of a thermoplastic material. A graphite containing sealing member is disposed in the bore and disposed between the insulator tube and the body of the connector assembly.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

Some embodiments include a flexible, pressure-balanced cable assembly. The cable assembly has a tubular-shaped flexible outer sleeve that surrounds an electrical cable. A plurality of seals is positioned along the length of the flexible sleeve within the space formed between the inner surface of the flexible sleeve and the outer surface of the electrical cable. The seals partition the space into a plurality of individual chambers. Each chamber is filled with dielectric fluid. The seals are independently and bi-directionally movable in response to a pressure difference between the inside of the cable assembly and the external environment thereby balancing the pressure between the inside of the cable assembly and the external environment.

Linking cable connector includes a lead frame held in an interior cavity of a cover. The lead frame includes conductive leads arranged side by side in a row and extending between a first end and an opposite second end of the lead frame. At least some adjacent conductive leads are spaced on a first lead pitch at the first end, and are spaced on a second lead pitch at the second end. The second lead pitch is less than the first lead pitch. The conductive leads engage and electrically connect to corresponding wire conductors of a first cable harness at the first end of the lead frame, and the conductive leads engage and electrically connect to corresponding wire conductors of a second cable harness at the second end of the lead frame such that the leads provide conductive paths between the first and second cable harnesses.
